WOORD VOORAF
“One size fits all”
De uitgaven voor de gezondheidszorg stijgen ieder jaar. De overheid en ziektekostenverzekeraars maken plannen om de gezondheidszorg betaalbaar te houden.Deze plannen
worden, zo mogelijk, gebaseerd op wetenschappelijk onderzoek (evidence-based medicine).
Hierbij wordt de patiënt een “gemiddelde” patiënt. In werkelijkheid is de patiënt echter
variabel: man óf vrouw, jong óf oud, sterk óf zwak, allochtoon óf autochtoon om een aantal
karakteristieken te benoemen.
Met patiëntgebonden onderzoek laten wij in het SFG zien hoe evidence-based medicine
werkt en waar het “one size fits all” model faalt.
In 2012 publiceerden in het Sint Franciscus Gasthuis werkzame medisch specialisten en
arts-assistenten een groot aantal artikelen in gezaghebbende internationale tijdschriften.
Absolute hoogtepunten zijn de publicatie van de tREACH studie, waarbij onderzocht werd
hoe patiënten met reuma het beste behandeld kunnen worden (Annals of the Rheumatic
Diseases) en de genetische (GWAS) studie die onderzocht welke genen belangrijk zijn
bij het kleiner worden van het volume van de hippocampus (een maat voor vroege dementie)
(Nature Genetics).
Onderzoek vanuit het Sint Franciscus Gasthuis werd verder gepresenteerd door middel
van voordrachten en posters. En twee echte SFG-onderzoekers verdedigden met
succes hun proefschrift: dr. A. Alipour en mw. dr. I. Leeuwenburgh. In diverse andere
proefschriften werd het Sint Franciscus Gasthuis terug gevonden in het dankwoord,
vanwege diverse bijdragen.
De Raad van Bestuur stimuleert het wetenschappelijk klimaat op diverse manieren.
In 2012 werd in goed overleg met de Centrale Opleidingscommissie, de Medische Staf
en het Leerhuis besloten om prof. dr. Jan Willem Cohen Tervaert aan te trekken als
specialist manager wetenschap met als doel het wetenschappelijk onderzoek in de
komende jaren op een nog hoger niveau te brengen. Samen met hem wil het Sint
Franciscus Gasthuis de wetenschappelijke "size" creëren die past bij patiëntenzorg en
opleidingen op top-niveau!

Abstract
Laser-induced fluorescence (LIF) and intrinsic fluorescence spectroscopy (IFS) have been
used experimentally for diagnosing coronary atherosclerosis. In this study, we demonstrated
the diagnostic superiority of IFS at 342-nm excitation (IFS(342)) versus LIF (LIF(342)) and
described a protocol for head-to-head comparison of old (LIF) versus new (IFS) generations
of similar diagnostic methods, labeled as “generational comparison model”. IFS(342) and
LIF(342) were modeled with basis spectra of media, fibrous caps, and superficial foam cells
and of their correspondent chemicals (elastin, collagen, and lipoproteins). The average
accuracy and receiver operating characteristic area under the curve of IFS(342) in single-,
double-, and triple-parameter diagnostic algorithm iterations, geared toward identifying 84
atherosclerotic specimens from a group of 117 coronary segments, was 90% ± 1% and 0.87
± 0.025, superior to LIF(342) (84% ± 3% and 0.84 ± 0.016; P = 0.0002 and 0.02, respectively)
in a generational comparison model.

In the revised 6th edition of the AJCC-TNM staging system for breast cancer, metastasis in
ipsilateral supraclavicular lymph node(s) is considered as a locoregional disease and
classified as N3c rather than M1 distant disease. The aim of this review was to search the
recent literature in order to investigate whether the reported treatment outcome of patients
with ipsilateral supraclavicular metastases in breast cancer patients justifies this revision.
A review of the recent English-language literature (January 2001-June 2012) concerning
breast cancer with supraclavicular involvement was performed.
A total number of six studies were included in the current review. All reported comparable
data with regard to treatment outcome after multimodality treatment, despite considerable
heterogeneity in study populations. Patients with ipsilateral supraclavicular lymph node
involvement showed outcomes more similar to locally advanced breast cancer patients
rather than patients with distant tumor spread.
It seems that the 2002 revision of the AJCC-TNM staging system for breast cancer has
appropriately reclassified patients with supraclavicular disease to a new category (N3c).
Re-diplacement of stable both-bone forearm fractures in children:
A randomised controlled multicentre trial.
INTRODUCTION: Displaced metaphyseal both-bone fractures of the distal forearm are
generally reduced and stabilised by an above-elbow cast (AEC) with or without additional
pinning. The purpose of this study was to find out if re-displacement of a reduced stable
metaphyseal both-bone fracture of the distal forearm in a child could be prevented by
stabilisation with Kirschner wires. METHODS: Consecutive children aged <16 years with a
displaced metaphyseal both-bone fracture of the distal forearm (n=128) that was stable
after reduction were randomised to AEC with or without percutaneous fixation with
Kirschner wires. The primary outcome was re-displacement of the fracture. RESULTS:
A total of 67 children were allocated to fracture reduction and AEC and 61 to reduction of
the fracture, fixation with Kirschner wires and AEC. The follow-up rate was 96% with a mean
follow-up of 7.1 months. Fractures treated with additional pinning showed less re-displacement (8% vs. 45%), less limitation of pronation and supination (mean limitation 6.9 (±9.4)°
vs. 14.3 (±13.6)°) but more complications (14 vs. 1). CONCLUSIONS: Pinning of apparent
stable both-bone fractures of the distal forearm in children might reduce fracture
re-displacement. The frequently seen complications of pinning might be reduced by a
proper surgical technique.

INTRODUCTION: Minimally displaced metaphyseal both-bone fractures of the distal forearm
in children are often treated with an above-elbow cast (AEC). Treatment with a below-elbow
cast (BEC) could give more comfort, but might lead to fracture displacement reducing
pronation and supination. Because this has not been systematically investigated, we set up
a randomised multicentre study. The purpose of this study was to find out whether BEC
causes equal limitation of pronation and supination but with higher comfort level, compared
with AEC.
PATIENTS AND METHODS: In four hospitals, consecutive children aged<16 (mean 7.1) years
with a minimally displaced metaphyseal both-bone fracture of the distal forearm were
randomised to 4 weeks BEC (n=35) or 4 weeks AEC (n=31). Primary outcome was limitation
of pronation and supination 6 months after initial trauma. The secondary outcomes were
cast comfort, limitation of flexion/extension of wrist/elbow, complications, cosmetics,
complaints, and radiological assessment. RESULTS: A group of 35 children received BEC and
31 children received AEC. All children attended for the final examination at a mean follow-up
of 7.0 months (range 5.0-11.6 months). Limitation of pronation and supination 6 months
after initial trauma showed no significant difference between the two groups [4.4° (± 5.8)
for BEC and 5.8° (± 9.8) for AEC]. Children treated with BEC had significantly higher cast
comfort on a visual analogue scale [5.6 (± 2.7) vs. 8.4 (± 1.4)] and needed significantly less
help with dressing (8.2 days vs. 15.1 days). Six complications occurred in the BEC group and
14 in the AEC group. Other secondary outcomes were similar between the two groups.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is becoming increasingly popular as
a stand-alone procedure for the treatment of morbidly obese patients. A direct posterior
approach to the angle of His was developed at our department to improve visualization of
the difficult dissection of the short gastric vessels and to facilitate proper mobilization of
the stomach around the left crus enabling safe realization of a tight sleeve. The technique
and its preliminary results are described. METHODS: LSG by posterior approach was
performed in a consecutive series of 445 (110 male/335 female, age 18-63 years, mean
body mass index 46 kg/m(2) (range 35-76)) patients between 2007 and 2010.
RESULTS: Weight loss defined as mean percent excess weight loss (%EWL) was 71%
(±26%) at 1 year, 69% (±25%) at 2 years, and 55% (±27%) at 3 years. Sixteen patients (4%)
developed postoperative intra-abdominal hematoma, 8 patients (2%) anastomotic leakage,
and 6 patients intra-abdominal abscess (1%), requiring reoperation in 20 patients (4%).
Five patients (1%) had pulmonary embolism. Thirty-day mortality rate was 0.2%.
CHIRURGIE
CONCLUSIONS: LSG by the posterior approach is a safe and effective procedure, enabling a
tight sleeve formation leading to satisfactory %EWL results. Since long-term results of LSG
are unknown, further studies are needed to define the exact place of the LSG as a standalone bariatric procedure.
Cancer stem cells and their potential implications for the treatment of solid
tumors.
Grotenhuis BA, Wijnhoven BP, Van Lanschot JJ.
J Surg Oncol.2012 Aug 1; 106(2): 209-15. Review.
PMID: 22371125.
BACKGROUND AND OBJECTIVES: There is increasing evidence that a variety of human cancers
is maintained by a subset of cells, cancer stem cells (CSCs), which sustain tumor growth,
underlie its malignant behavior, and possibly initiate distant metastases. The aim of this
review is to evaluate the current evidence for the existence of CSCs and the implications on
the present management and treatment of solid tumors.
METHODS: A retrospective review of the English-language literature (1997-2010) concerning
CSCs and their therapeutic implications was performed. RESULTS: CSCs are characterized by
two main properties of normal stem cells: Self-renewal and differentiation, which are best
assayed by serial transplantation experiments in immunodeficient mice. Cell-surface
antigens that mark cell populations enriched for CSCs have been identified in various solid
tumors. As such, the very existence of CSCs has vast clinical implications with regard to
cancer treatment. The development of tailor-made CSC-targeted therapies (including
therapies directed at these CSC-specific surface markers, and reversal of the intrinsic
resistance of CSCs to chemo- and radiotherapy) entails great promises. However, normal
stem cell toxicity and treatment resistance have been recognized as serious problems.
CONCLUSION: The growing evidence indicating that CSCs drive and maintain various types of
solid human malignancies has important implications for the treatment of patients. However,
over the years the development of CSC-targeted therapies has faced a number of potential
hurdles, which must be considered carefully in order to maximize the chance that such
therapies will be successful.

PURPOSE: To evaluate all functional aspects of patients with longitudinal radial dysplasia
and to clarify the relationship between body functions on the one hand and limitations in
activity and participation on the other hand. Methods: Thirty-one arms of seventeen adult
patients with longitudinal radial dysplasia were analysed. Body function was assessed by
measuring grip and pinch strength and active range of motion (ROM) of the hand. Activities
were measured using the “Sequential Occupational Dexterity Assessment “, to measure
perceived restrictions in participation the “Impact on Participation and Autonomy questionnaire” was used. Relationships between severity of dysplasia, body function, participation
and activity were determined. Results: Patients with a severe type scored significantly lower
in body function scores than patients with a mild form. Patients with limited active finger
joint motion performed worse on activities. We found no significant differences in activity
and participation between mild or severe types and found no correlation in participation
scores. Conclusion: Although considerable restrictions in joint mobility and strength were
revealed, little or no limitations on the activity and participation level were found. Limitations in body functions hardly influenced capacity on activity level and did not influence
participation in societal roles.

PMID: 22493363.
AIM: Insulin-like growth factor-1 receptor (IGF1R) is a tyrosine kinase receptor mediating
cell growth and survival of cancer cells. We studied responses to IGF1R tyrosine kinase
inhibitor NVP-AEW541 combined with conventional systemic drugs in breast cancer cell
lines of different clinical subtype.
MATERIALS AND METHODS: Sensitivity to NVP-AEW541, single treatment and combinations
with tamoxifen, trastuzumab, doxorubicin or paclitaxel, was tested in MCF7, SKBR3 and
T47D cells. Cells were assayed for proliferation, cell death, cell cycle distribution and
phosphorylation of proteins downstream of IGF1R. RESULTS: Treatment of NVP-AEW541
resulted in reduced proliferation, G-1 cell cycle arrest and reduced phosphorylation of
protein kinase B (AKT) and extracellular-signal-regulated protein kinase (ERK). Sensitivity
to IGF1R tyrosine kinase inhibition was low in T47D cells, despite their high IGF1R expression. NVP-AEW541 combined with trastuzumab had synergistic cytotoxic effects in T47D

cells, and additive effects were shown in MCF7 and SKBR3 cells. Also, combination with
doxorubicin had antagonistic effects in T47D cells. Doxorubicin caused up-regulation of
phosphorylated ERK in T47D cells, which was not inhibited by NVP-AEW541. CONCLUSION:
Antagonistic effects should be anticipated when IGF1R inhibitors are combined with
conventional systemic drugs in a subset of breast tumors. Development of functional
biomarkers predicting tumor response to tailored IGF1R therapy is warranted.
The surgical anatomy of the small saphenous vein and adjacent nerves in
relation to endovenous thermal ablatio.
BACKGROUND: Thermal damage to peripheral nerves is a known complication of endovenous
thermal ablation (EVA) of the small saphenous vein (SSV). Therefore, the main objective of
this anatomic study was to define a safe zone in the lower leg where EVA of the SSV can be
performed safely. METHODS: The anatomy of the SSV and adjacent nerves was studied in 20
embalmed human specimens. The absolute distances between the SSV and the sural nerve
(SN) (closest/nearest branch) were measured over the complete length of the leg (>120 data
points per leg), and the presence of the interlaying deep fascia was mapped. The distance
between the SSV and the tibial nerve (TN) and the common peroneal nerve was assessed.
A new analysis method, computer-assisted surgical anatomy mapping, was used to visualize
the gathered data. RESULTS: The distance between the SSV and the SN was highly variable.
In the proximal one-third of the lower leg, the distance between the vein and the nerve was <5
mm in 70% of the legs. In 95%, the deep fascia was present between the SSV and the SN.
In the distal two-thirds of the lower leg, the distance between the vein and the nerve was <5
mm in 90% of the legs. The deep fascia was present between both structures in 15%. In 19
legs, the SN partially ran beneath the deep fascia. In the saphenopopliteal region, the average
shortest distance between the SSV and the TN was 4.4 mm. In 20%, the distance was <1 mm.
The average, shortest distance between the SSV and the common peroneal nerve was 14.2
mm. The distance was <1 mm in one leg.
CONCLUSIONS: At the saphenopopliteal region, the TN is at risk during EVA. In the distal
two-thirds of the lower leg, the SN is at risk for (thermal) damage due to the small distance
to the SSV and the absence of the deep fascia between both structures. The proximal
one-third of the lower leg is the optimal region for EVA of the SSV to avoid nerve damage; the
fascia between the SSV and the SN is a natural barrier in this region that could preclude
(thermal) damage to the nerve.

room (OR) teams that remain fixed for the day instead of OR teams that vary during the day.
METHODS: Data were collected in 2 general teaching hospitals, consisting of patientrelated
demographic and intraoperative data and of staffrelated survey data on team work and
safety climate. The procedure durations of fixed and conventional OR teams were analyzed
by comparison of means tests and by regression methods to control for the effects of
surgeon, surgical experience, and procedure type. RESULTS: For both hospitals, we obtained
the following 4 results for working on bariatric procedures with OR teams that remained
fixed for the day. First, patient outcomes did not worsen. Second, teamwork and safety
climate (both measured on a 5-point scale) improved significantly, for teamwork + 0.86
(95% confidence interval [CI], 0.54 to 1.18) and for safety climate + 0.75 (95% CI, 0.40 to
1.11). Third, the procedures were performed significantly faster, as both the mean and the
SD of procedure durations decreased. After correcting for learning effects, the average
reduction of durations was 10.8% (99% CI, 5.0% to 15.3%, or 4 to 13 minutes). This gain
was mainly realized for surgical time (12%; 99% CI, 5% to 18%, or 3 to 11 minutes). The
effect on peripheral time, defined as procedure time minus surgical time, is not significant
(3%; 99% CI, -6% to 12%, or -1 to 3 minutes). Fourth, additional gains were obtained by
performing the same type of procedure multiple times within the same day (5% per every
next procedure of the same type; 99% CI, 3% to 7%, or 3 to 6 minutes).

Although early detection of Lynch syndrome (LS) is important, a considerable proportion of
patients with LS remains unrecognized. We aimed to study the yield of LS detection by
routine molecular analyses in colorectal cancer (CRC) patients until 70 years of age. We
prospectively included consecutive CRC patients ≤70 years. Tumour specimens were
analysed for microsatellite instability (MSI), immunohistochemical mismatch-repair protein
expression and MLH1-promoter methylation. Tumours were classified as either: (a) likely
caused by LS; (b) sporadic microsatellite-unstable (MSI-H); or (c) microsatellite-stable
(MSS). Predictors of LS were determined by multivariable logistic regression. A total of 1117
CRC patients (57% males, median age 61 years) were included. Fifty patients (4.5%, 95% CI
3.4-5.9) were likely to have LS, and 71 had a sporadic MSI-H tumour (6.4%, 95% CI 5.1-8.0).
Thirty-five patients likely to have LS (70%) were aged > 50 years. A molecular profile
compatible with LS was detected in 10% (15/144) of patients aged ≤50, in 4% (15/377) of
those aged 51-60 and in 3% (20/596) of patients > 61 years. Compared to MSS cases,
patients likely to have LS were significantly younger (OR 3.9, 95% CI 1.7-8.7) and more often
had right-sided CRCs (OR 14, 95% CI 6.0-34). In conclusion, molecular screening for LS in
CRC patients ≤70 years leads to identification of a molecular profile compatible with LS in
4.5% of patients, with most of them not fulfilling the age criterion (≤50 years) routinely
used for LS assessment. Routine use of MSI testing may be considered in CRC patients up
to the age of 70 years, with a central role for the pathologist in the selection of patients.

BACKGROUND: The new 7th edition of the Union for International Cancer Control-American
Joint Committee on Cancer (UICC-AJCC) tumor, node, metastasis (TNM) staging system is
the ratification of data-driven recommendations from the Worldwide Esophageal Cancer
Collaboration database. Generalizability remains questionable for single institutions. The
present study serves as a validation of the 7th edition of the TNM system in a prospective
cohort of patients with predominantly adenocarcinomas from a single institution.METHODS:
Included were patients who underwent transhiatal esophagectomy with curative intent
between 1991 and 2008 for invasive carcinoma of the esophagus or gastroesophageal
junction. Excluded were patients who had received neoadjuvant chemo(radio)therapy,
patients after a noncurative resection and patients who died in the hospital. Tumors were
staged according to both the 6th and the 7th editions of the UICC-AJCC staging systems.
Survival was calculated by the Kaplan-Meier method, and multivariate analysis was performed with a Cox regression model. The likelihood ratio chi-square test related to the Cox
regression model and the Akaike information criterion were used for measuring goodness of fit.
RESULTS: A study population of 358 patients was identified. All patients underwent transhiatal esophagectomy for adenocarcinoma. Overall 5-year survival rate was 38%. Univariate
analysis revealed that pT stage, pN stage, and pM stage significantly predicted overall
survival. Prediction was best for the 7th edition, stratifying for all substages.CONCLUSIONS:
The application of the 7th UICC-AJCC staging system results in a better prognostic stratification of overall survival compared to the 6th edition. The fact that the 7th edition performs
better predominantly in patients with adenocarcinomas who underwent a transhiatal surgical
approach, in addition to findings from earlier research in other cohorts, supports its
generalizability for different esophageal cancer practices.

OBJECTIVE: To determine the risk factors for symptomatic anastomotic leakage (AL) after
colorectal resection. DESIGN: Review of records of patients who participated in the Analysis of
Predictive Parameters for Evident Anastomotic Leakage study. SETTING: Eight health centers.
PATIENTS: Two hundred fifty-nine patients who underwent left-sided colorectal anastomoses.
INTERVENTION: Corticosteroids taken as long-term medication for underlying disease or
perioperatively for the prevention of postoperative pulmonary complications. MAIN OUTCOME
MEASURES: Prospective evaluations for risk factors for symptomatic AL. RESULTS: In 23% of
patients, a defunctioning stoma was constructed. The incidence of AL was 7.3%. The clinical
course of patients with AL showed that in 21% of leaks, the drain indicated leakage; in the
remaining patients, computed tomography or laparotomy resulted equally often in the

detection of AL. In 50% of patients with AL, a Hartmann operation was needed. The
incidence of AL was significantly higher in patients with pulmonary comorbidity (22.6%
leakage), patients taking corticosteroids as longterm medication (50% leakage), and
patients taking corticosteroids perioperatively (19% leakage). Perioperative corticosteroids
were prescribed in 8% of patients for the prevention of postoperative pulmonary
complications.
CONCLUSIONS: We found a significantly increased incidence of AL in patients treated with
long-term corticosteroids and perioperative corticosteroids for pulmonary comorbidity.
Therefore, we recommend that in this patient category, anastomoses should be protected
by a diverting stoma or a Hartmann procedure should be considered to avoid AL.

Granulomateuze secundaire syfilis, een zeldzame uiting van een polymorf

PMID: 22894801.
BACKGROUND: Due to a great diversity of clinical presentations secondary syphilis can
mimic various skin diseases, which means that the diagnosis of this sexually transmitted
condition can be missed. Occurrence of a granulomatous inflammatory reaction in
secondary syphilis is rare and may be confused with other granulomatous dermatoses.
CASE DESCRIPTION: We present a 37-year-old homosexual male with a granulomatous
dermatitis due to secondary syphilis. The differential diagnosis based on clinical and
histopathological findings was lengthy and the initial syphilitic serology results were
negative, resulting in delayed diagnosis. After revision of the histopathology and repeated
serological testing secondary syphilis could be diagnosed.
CONCLUSION: Not only the clinical, but also the histopathological presentation of secondary
syphilis is variable. To prevent transmission, treatment delay and complications, we
recommend repeating syphilitic serology following negative results if there is clinical or
histopathological suspicion of this disease, especially in patients displaying high-risk
behaviour. Syphilis should be also excluded in granulomatous dermatoses with plasma cells.

We report a case of a 26 year old woman with rash, lymphadenopathy, liver enzyme
abnormalities and spiking fever. She was diagnosed with drug-induced hypersensitivity
syndrome (DHS) to lamotrigine. Spiking fever in relation to drug-induced hypersensitivity
syndrome has not earlier been described in adults. Spiking fever is an important symptom
of the wide spectrum of disease presentation. The syndrome is commonly referred to as
either Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) or DHS. In accord with
previous authors we see both syndromes as two ends of a spectrum, with a wide range of
symptoms and presentations. Therefore we plea for unity in nomenclature.

Int Urogynecol J 2012; 23: 481-6. PMID: 22086264.
INTRODUCTION AND HYPOTHESIS: The aim of this study was to evaluate short-term anatomic
and functional outcomes and safety of laparoscopic sacrocolpopexy with bone anchor
fixation.METHODS: A prospective cohort study of women undergoing laparoscopic sacrocolpopexy between 2004 and 2009. Anatomic outcome was assessed using the pelvic organ
prolapse quantification score (POP-Q). Functional outcomes were assessed using the
Urogenital Distress Inventory, Defecatory Distress Inventory, and the Incontinence Impact
Questionnaire preoperatively and at 6 months postoperatively. The Wilcoxon signed rank test
was used to test differences between related samples. RESULTS: Forty-nine women
underwent laparoscopic sacrocolpopexy. The objective success rate in the apical compartment was 98%, subjective success rate was 79%. One mesh exposure (2%) was found. One
conversion was necessary due to injury to the ileum. CONCLUSIONS: Laparoscopic sacrocolpopexy with bone anchor fixation is a safe and efficacious treatment for apical compartment prolapse. It provides excellent apical support and good functional outcome 6 months
postoperatively.

Consecutive EC patients = 70 years were included prospectively in eight Dutch centres.
EC specimens were analysed for MSI, IHC of four MMR proteins, MMR gene methylation
status and BRAF-mutations. tumours were classified as; 1) likely to be caused by LS, 2)
sporadic MSI-H, or 3) microsatellite stable (MSS).
Tumour specimens of 179 patients (median age 61 years, IQR 57-66) were analysed. In our
study 92% of included patients were over 50 years of age. Eleven EC patients were found
likely to have LS (6%; 95% CI 3-11%), including 1 patient suspected of an MLH1, 2 of an
MSH2, 6 of an MSH6 and 2 of a PMS2 gene defect. Germline mutation analyses revealed 7
MMR gene germline mutations. Ten patients likely to have LS (92%) were older than 50
years. In addition, 31 sporadic MSI-H tumours with MLH1 promoter hypermethylation
(17%; 95% CI 13-24%) were identified.
Molecular screening for LS in patients with EC diagnosed = 70 years, leads to identification
of a profile likely to have LS in 6% of cases. New screening guidelines for LS are needed,
including recommendations for EC patients older than 50 years of age.
Fluid shift out of the fetal circulation during intrauterine red cell

OBJECTIVES: Intrauterine transfusion presents a considerable burden on the fetal circulation by increasing volume and pressure. Already during transfusion, a fluid shift out of the
fetal circulation occurs. Aim of the study was to quantify the intraprocedural fluid shift, and
the effect of procedural and fetal characteristics on this fluid shift. METHODS: In 95
alloimmunized pregnancies, we calculated fluid shift at first intrauterine transfusions, by
determining initial and final blood volumes. We evaluated the association of the fluid shift
with speed and volume of transfusion, severity of anemia and presence of hydrops.
RESULTS: Of the included fetuses, 11 were mildly hydropic and 4 were severely hydropic. A
mean fluid shift of 36% of transfused volume was found. Fluid shift related positively to
transfused volume (p<0.00). The percentage fluid shift of transfused volume was inversely
related to speed of transfusion (ml/kg/min) (p<0.041) and not related to severity of anemia
(p=0.55) or hydrops (p=0.66). At low gestational age, fetuses had been unintentionally
burdened with relative high volume and speed of transfusion. CONCLUSION: Around one
third of transfused volume is lost from the intravascular compartment already during
intrauterine transfusion. A large variation, partly explained by volume and speed of
transfusion, was observed. Neither severity of anemia or hydrops played a clear-cut role,
thus other factors may explain the variation in fluid shift. The probability that hematocrit
will still increase after transfusion, due to a continuing fluid shift, should be considered in
transfusion policy. Advice is given on gestational age adjusted speed of transfusion.

OBJECTIVE: Controversial data are available as to whether to perform a simultaneous
abdominal or vaginal colposuspension operation in laparoscopic sacrocolpopexy procedures. We wanted to evaluate the effect of a modified laparoscopic operation technique on
urodynamic parameters and lower urinary tract symptoms. DESIGN: Prospective single
center cohort study. SETTING: Teaching hospital. POPULATION: Forty-nine consecutive
patients who underwent a modified laparoscopic sacrocolpopexy/hysteropexy operation
using bone anchor fixation and synthetic mesh, performed by the same laparoscopic
surgeons. METHODS: Pre- and postoperative multichannel urodynamic evaluation and
validated questionnaires. The same urologist, blinded to the results of the questionnaire
survey, interpreted all urodynamic evaluations. MAIN OUTCOME MEASURES: The effects of
surgery on pelvic anatomy and patient satisfaction, urodynamic observations and diagnoses and symptom scores in validated questionnaires. RESULTS: Forty-two patients
consented to pre- and postoperative urodynamic evaluation. Laparoscopic sacrocolpopexy
successfully corrected vaginal vault prolapse in all 42 patients with urodynamic evaluation
six months after surgery. The bladder volume at first desire to void was significantly
increased and the maximal detrusor pressure at voiding phase was significantly decreased.
In the questionnaires, irritative and storage voiding symptoms were significantly decreased.
CONCLUSIONS: The results of the study demonstrate that there are no adverse urodynamic
findings following this modified technique for laparoscopic sacrocolpopexy. The statistically
significant urodynamic improvements are in accordance with the scores on the Urogenital
Distress Inventory questionnaires. These results do not support a simultaneous routine
prophylactic colposuspension procedure.

OBJECTIVE: Sarcoidosis is a systemic inflammatory disorder characterized by granulomas.
Although the aetiology is unknown, sarcoidosis is thought to be mediated by Th1 lymphocytes. Recently, IL-17A has been implicated in granuloma formation in various diseases,
including tuberculosis. Therefore, we hypothesized that Th17 cells play a role in sarcoidosis,
paralleling recent findings in autoimmune diseases such as RA. The aim of our study was to
investigate the role of Th17 cells in sarcoidosis.
METHODS: T cells were investigated by intracellular flow cytometry and immunohistochemistry, in blood, bronchoalveolar lavages (BALs) and bronchial mucosal biopsies from a
cohort of newly diagnosed sarcoidosis patients and healthy controls.

CONTEXT: Amiodarone-induced thyrotoxicosis (AIT) type 2 is self-limiting in nature, but
most physicians are reluctant to continue amiodarone. When prednisone fails to restore
euthyroidism, possibly due to mixed cases of AIT type 1 and 2, perchlorate (ClO(4)) might be
useful because ClO(4) reduces the cytotoxic effect of amiodarone on thyrocytes.
OBJECTIVES: Our objectives were to demonstrate the feasibility of continuation of amiodarone in AIT type 2 and to evaluate the usefulness of ClO(4) (given alone or in combination
with prednisone) in AIT type 2.
DESIGN AND SETTING: A randomized multicenter study was conducted in 10 Dutch hospitals.
METHODS: Patients with AIT type 2 were randomized to receive prednisone 30 mg/d (group
A, n = 12), sodium perchlorate 500 mg twice daily (group B, n = 14), or prednisone plus
perchlorate (group C, n = 10); all patients continued amiodarone and were also treated with
methimazole 30 mg/d. Follow-up was 2 yr.
MAIN OUTCOME MEASURES: Treatment efficacy (defined as TSH values = 0.4 mU/liter under
continuation of amiodarone) and recurrent thyrotoxicosis were evaluated.
RESULTS: Initial therapy was efficacious in 100, 71, and 100% of groups A, B, and C,
respectively (P = 0.03). The 29% failures in group B became euthyroid after addition of
prednisone. Neither the time to reach TSH of 0.4 mU/liter or higher [8 wk (4-20), 14 wk
(4-32), and 12 wk (4-28) in groups A, B, and C respectively] nor the time to reach free T(4)
of 25 pmol/liter or below [4 wk (4-20), 12 wk (4-20), and 8 wk (4-20) in groups A, B, and C)
were significantly different between groups (values as median with range). Recurrent
thyrotoxicosis occurred in 8.3%.
CONCLUSION: Euthyroidism was reached despite continuation of amiodarone in all patients.
Prednisone remains the preferred treatment modality of AIT type 2, because perchlorate
given alone or in combination with prednisone had no better outcomes.

RESULTS: Circulating memory CD4(+) T-cell populations of sarcoidosis patients contained
significantly increased proportions of IL-17A(+) cells when compared with healthy controls.
Interestingly, proportions of IL-17A/IFN-γ and IL-17A/IL-4 double-producing cells were
significantly increased in blood of sarcoidosis patients and were present in substantial
numbers in BAL. In granuloma-containing, but not in non-granulomatous sarcoidosis
biopsies, we found significantly increased numbers of IL-17A(+) T cells, located in and around
granulomas throughout the lamina propria. IL-22(+) T cells were increased in the subepithelial layer.
CONCLUSIONS: Enhanced IL-17A expression in granulomas and the presence of IL-17A(+),
IL-17A(+)IFN-γ(+) and IL-17A(+)IL-4(+)memory Th cells in the circulation and BAL indicate
Th17 cell involvement in granuloma induction or maintenance in sarcoidosis. Therefore,

Chronic obstructive pulmonary disease (COPD) is associated with pulmonary and systemic
inflammation. Both CD4+ and CD8+ T-lymphocytes play a key role in COPD pathogenesis,
Witt cytokine profiles in circulating T-lymphocytes have not been well characterised. Here we
report the analysis of peripheral blood T-cells from 30 stable COPD patients and 10 healthy
never-smokers for interferon (IFN)-γ, interleukin (IL)-4, tumour necrosis factor (TNF)-α and
the T-helper 17 cytokines IL-17A, IL-17F and IL-22 by intracellular flow cytometry. We found
significantly increased proportions of IFN-γ+ and TNF-α+ CD8+ T-cells in COPD patients,
when compared with healthy controls. This was most evident in patients with less severe
disease. In contrast, expression profiles in circulating CD4+ T-cells were similar in COPD
patients and healthy controls for all cytokines tested, except for IL-17F. COPD patients with
more severely reduced diffusing capacity had lower proportions of IL-17A+ CD4+ T-cells.
Proportions of IL-22+ cells in the CD4+ memory T-cell population were significantly increased
in active smokers, when compared with past smokers. Collectively, this comprehensive
cytokine analysis of circulating T-cells in COPD patients revealed a correlation for CD8+
T-cells between Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage and IFN-γ
or TNF-α expression, but not for CD4+ T-cells.

A physician’s guide for the management of hypertriglyceridemia: the
etiology of hypertiglyceridemia determines treatment strategy.
Hypertriglyceridemia is a common lipid disorder associated to different, highly prevalent
metabolic derangements like diabetes mellitus, the metabolic syndrome and obesity. The
choice of treatment depends on the underlying pathogenesis and the consequences for
atherosclerosis or pancreatitis. A family history, physical examination and analysis of the
lipid profile including measurement of apolipoprotein B or non-HDL-C are necessary to
establish the underlying primary or secondary cause. Due to physiological diurnal variations
of triglycerides (TG), the time of measurement (fasting or postprandial) should be taken
into account when evaluating TG values. Increased awareness arises concerning the impact
of postprandial hypertriglyceridemia on the development of atherosclerosis. Hypertriglyceridemia is strongly associated to postprandial hyperlipidemia, remnant accumulation, increased small dense LDL concentrations, low HDL-C, increased oxidative stress, endothelial
dysfunction, leukocyte activation and insulin resistance. All these factors are strongly linked
to the development of atherosclerosis. Treatment should be aimed at reducing the
secretion of triglyceride-rich lipoproteins, increasing intravascular lipolysis and reducing
the number of circulating remnants. The main intervention is a change of lifestyle with
decreased alcohol consumption, increased physical activity, dietary changes and, if
applicable, adaptation of used medication. Fibrates, fish oil and nicotinic acid are the first
choice of treatment in sporadic and familial hypertriglyceridemia to reduce the risk of
pancreatitis, whereas high dose statins, sometimes in combination with fibrates, nicotinic
acid, or fish oil capsules, are indicated for familial combined hyperlipidemia. Statins are
necessary to reach low LDL-C concentrations in patients with type 2 diabetes mellitus and
statin dosage should be increased when hypertriglyceridemia is present to reach secondary
treatment targets for apolipoprotein B or non-HDL-C. Finally, family screening is mandatory
to detect familial lipid disorders for early intervention in other family members.

micro- and macrovascular complications in Type 2 diabetes in a primary care setting.
The present cross-sectional study aims to confirm the association between skin autofluorescence and diabetic complications in patients with Type 2 diabetes in a multi-centre secondary care setting.
METHODS: We analysed 563 subjects with Type 2 diabetes mellitus from five Dutch hospitals.
RESULTS: Median age was 64 years, median duration of diabetes 13 years and median
HbA(1c) 58 mmol/mol (7.5%). Sixty-one per cent of patients had microvascular complications (38% nephropathy, 36% retinopathy, 35% neuropathy) and 42% had macrovascular
complications. Median UK Prospective Diabetes Study 10-year risk for coronary events was
19%. Median skin autofluorescence was elevated compared with age-matched healthy
control subjects: 2.77 (interquartile range 2.39-3.28) vs. 2.46 (2.08-2.84) arbitrary units.
Skin autofluorescence was particularly increased in patients with complications: no
complications, median 2.56 (2.26-2.90); microvascular complications, 2.79 (2.38-3.29);
macrovascular complications, 2.85 (2.41-3.41); both micro- and macrovascular complications, 2.96 (2.56-3.60) arbitrary units, P < 0.001. Logistic regression analysis showed that age,
duration of diabetes, renal function, gender, atrial fibrillation and skin autofluorescence were
independently associated with macrovascular complications. Multiple regression analysis
identified age, smoking, renal function, macrovascular complications and the number of
microvascular complications as the determinants of skin autofluorescence.
CONCLUSIONS: This study confirms that skin autofluorescence is increased in patients with
Type 2 diabetes in a secondary care setting. Skin autofluorescence was associated with
macrovascular complications in patients with diabetes and this association was independent
of classical risk factors.

INTRODUCTION: Impaired free fatty acid (FFA) metabolism is closely linked to insulin
resistance. Our aim was to evaluate plasma FFA changes in insulin resistance in a physiological situation after improvement of insulin sensitivity by metformin. Methods. A double-blind,
placebo-controlled intervention with metformin was carried out in patients with insulin
resistance. Nineteen patients were randomized to receive metformin 850 mg b.i.d. during 6
weeks or placebo. Participants underwent a mental stress test and an oral glucose tolerance
test (OGTT) before and after treatment. Results. Fasting plasma glucose, FFA, and HOMA-IR
tended to decrease after metformin, suggesting improved insulin sensitivity. FFA concentrations during the mental stress test showed a similar pattern after metformin, albeit lower at all
time points, in contrast to the placebo group. The decrease in fasting plasma FFAs was
positively associated to the decrease in HbA1c (r = 0.70; P = 0.03) and in fasting glucose
(r = 0.74; P = 0.01). The suppression of plasma FFAs during OGTT did not change by
metformin or placebo. Conclusion. Metformin in insulin resistance did not lead to improved
FFA dynamics despite a trend of improved insulin sensitivity. Metformin most likely decreases
plasma FFAs mainly by suppressing fasting FFA concentrations and not by suppression of
acute stress-induced lipolysis.

Eryhropoiesis-stimulating agents have demonstrated tissue-protective effects in experimental models of ischemia-reperfusion injury. PROTECT was a 12-month, randomized,
double-blind, placebo-controlled, single center study with high-dose recombinant human
erythropoietin-β (Epoetin) in 92 donation after cardiac death (DCD) kidney transplant
recipients. Patients were randomized to receive an intravenous bolus of Epoetin (3.3 × 10(4)
international unit (IU); n = 45) or placebo (saline 0.9% solution; n = 47) on 3 consecutive
days, starting 3-4 h before the transplantation and 24 h and 48 h after reperfusion. The
immunosuppressive regimen included an anti-CD25 antibody, steroids, mycophenolate
mofetil and delayed introduction of cyclosporine. Primary end point was a composite of the
incidence of primary nonfunction and delayed graft function, either defined by spontaneous
functional recovery or need for dialysis in the first week. Secondary objectives included
duration of delayed function, renal function and proteinuria up to 1 year and thrombotic
adverse events. Results showed no differences in the incidence or duration of delayed graft
function and/or primary nonfunction (Epoetin 77.8 vs. placebo 78.7%, p = 1.00). Epoetin
treatment significantly increased the risk of thrombotic events at 1 month and 1 year
(Epoetin 24.4% vs. placebo 6.4%, p = 0.02).
Pitfalls in urinary complement measurements.
Local activation of the complement system has been associated with ischemia/reperfusion
injury following kidney transplantation and tubular injury under proteinuric conditions.
The soluble terminal complement complex sC5b-9 is a stable end-product of the complement cascade, and as such a promising urinary biomarker. In the early post-transplant
period we found high urinary levels of sC5b-9, significantly correlating with the degree of
proteinuria, suggesting activation of filtered complement components at the tubular
epithelial surface of the kidney. However, when mimicking proteinuria in vitro by exposing
serum (or blood) to urine (both negative for sC5b-9), we found extensive generation of
sC5b-9 in urine. This process was inhibited by EDTA, confirming activation of the complement system. In conclusion, although sC5b-9 is an attractive urinary biomarker, one should
be aware of the risk of extra-renal complement activation independent of a renal contribution. This may be of special interest when measuring urinary sC5b-9 following kidney
transplantation in which procedure-related (microscopic) hematuria and proteinuria are
common.

Tamoxifen undergoes biotransformation into several metabolites, including endoxifen.
Differences in metabolism contribute to the interindividual variability in endoxifen concentrations, potentially affecting treatment efficacy. We evaluated the effects of cytochrome P450
(CYP) induction by rifampicin on the exposure levels of tamoxifen and its metabolites and
found that coadministration of rifampicin resulted in markedly reduced (up to 86%, P ≤
0.040) concentrations of tamoxifen and its metabolites. Given the extensive metabolism
undergone by tamoxifen, several factors may have contributed to this effect. Similar
drug-drug interactions may exist between tamoxifen and other strong CYP inducers.

This phase I, open-label, dose-escalation study assessed the maximum-tolerated dose,
safety, pharmacokinetics, and preliminary antitumor activity of pazopanib plus lapatinib
combination therapy in patients with solid tumors. Patients were to take pazopanib and
lapatinib orally once daily in a fasting condition. During the escalation phase, pazopanib and
lapatinib doses were escalated in serial patient cohorts, and a limited blood sampling scheme
was applied for pharmacokinetic evaluation. In the expansion phase, potential pharmacokinetic interaction between pazopanib and lapatinib was evaluated more extensively. Seventy-five
patients were treated. Multiple dosing levels were studied, combining pazopanib up to
800 mg/day with lapatinib up to 1,500 mg/day. Dose-limiting toxicities observed included
grade 3 neutropenia, fatigue, asymptomatic decline in left ventricular ejection fraction,
diarrhea, and liver enzyme elevations. The most common drug-related adverse events were
diarrhea, nausea, anorexia, fatigue, vomiting, rash, hair depigmentation, and hypertension.
The dose recommended for further evaluation was pazopanib 800 mg plus lapatinib 1,500 mg
(paz-800/lap-1500). No clinically significant drug-drug interaction was observed at the
paz-400/lap-1000 level. However, at paz-800/lap-1500, an increase in both the AUC(0-t) and
C(max) of pazopanib was observed. Four partial responses were observed in patients with
renal cancer (n=2), giant-cell tumor of the bone (n=1), and thyroid cancer (n=1). Stable
disease for ≥18 weeks was seen in 12 patients. Pazopanib and lapatinib can be administered
in combination at their respective single-agent doses with an acceptable safety profile.
Further evaluation of the combination will be pursued, exploring both paz-800/lap-1500 and
paz-400/lap-1000.

Small bowel angioedema due to acquired C1 inhibitor deficiency:
a case report and overview.
Oostergo T, Prins G, Schrama YC, Leeuwenburgh I.
Eur J Gastroenterol Hepatol. 2012 Dec 18. [Epub ahead of print]
PMID: 23255023.
Acquired angioedema is a rare disorder caused by an acquired deficiency of C1 inhibitor. It is
characterized by nonpitting, nonpruritic subcutaneous or submucosal edema of the skin, or
of the respiratory or gastrointestinal tract. When localized in the gastrointestinal tract, it
can cause severe abdominal pain, mimicking an acute surgical abdomen, or chronic
recurrent pain of moderate intensity. We report a case of a 48-year-old man presenting with
recurrent episodes of hypotension and abdominal pain. Computed tomography of the
abdomen showed edema of the small bowel. The first determinations of C1 inhibitor level
and activity, measured in a symptom-free period, were normal. Repetition of the laboratory
tests in the acute phase, however, showed a low C1 inhibitor level. Further diagnostic
work-up indicated an acquired C1 inhibitor deficiency caused by a monoclonal gammopathy. He was treated with tranexamic acid as prophylaxis for his frequent attacks and to
date, he has remained symptom free. Acquired C1 inhibitor deficiency is a rare cause of
angioedema and is, among others, related to autoantibodies and abnormal B-cell proliferation, for example monoclonal gammopathy. The diagnosis of acquired C1 inhibitor
deficiency is made on the basis of the medical history and on the level and activity of
plasma C4, C1q, and C1 inhibitor. In case of high suspicion and a normal C1 inhibitor activity,
it is recommended to repeat this test during an angioedema attack. Early diagnosis is
important for the treatment of severe, potentially life-threatening attacks and to start
prophylactic treatment in patients with frequent or severe angioedema attacks.
Local and systemic cytokine profiles in non-severe and severe
community-acquired pneumonia.
Local inflammatory responses in community-acquired pneumonia (CAP) remain insufficiently elucidated, especially in patients with non-severe CAP. In this study we determined local
and systemic cytokine responses in CAP patients and correlated these with disease severity
and other clinical parameters.Levels of interleukin (IL)-6, IL-8, IL-10, IL-1β, tumour necrosis
factor (TNF)α, interferon (IFN)γ, IL-22, IL-17A and IL-4 were determined in bronchoalveolar
lavage (BAL) fluid and serum of 20 CAP patients upon admission and 10 healthy individuals.
Systemic cytokine levels were also measured on days 7 and 30.In BAL fluid of CAP patients,
levels of IL-6, IL-8, and IFNγ were significantly increased compared with healthy individuals,
but no correlations with disease severity were found. Systemic levels of IL-6, IL-10 and IFNγ
were significantly higher in severe CAP patients than in non-severe CAP patients and
healthy individuals. Moreover, these cytokines showed a significant correlation with the
pneumonia severity index (PSI). In the total group of CAP patients systemic IL-8 and IL-22
levels were also increased compared with healthy individuals.We therefore conclude that
IL-6, IL-10 and IFNγ are important cytokines in CAP, although differences in disease severity
upon admission are only reflected by systemic levels of these cytokines.

PMID: 21876813.
The use of combination antiretroviral therapy (CART) in HIV-infected patients has resulted in
a dramatic decline in AIDS-related mortality. However, mortality due to non-AIDS conditions,
particularly cardiovascular disease (CVD) seems to increase in this population. CART has been
associated with several metabolic risk factors, including insulin resistance, low HDL-cholesterol, hypertriglyceridemia and postprandial hyperlipidemia. In addition, HIV itself, as well as
specific antiretroviral agents, may further increase cardiovascular risk by interfering with
endothelial function. As the HIV population is aging, CVD may become an increasingly growing
health problem in the future. Therefore, early diagnosis and treatment of cardiovascular risk
factors is warranted in this population. This paper reviews the contribution of both, HIV
infection and CART, to insulin resistance, postprandial hyperlipidemia and cardiovascular risk
in HIV-infected patients. Strategies to reduce cardiovascular risk are also discussed.

BACKGROUND: Postprandial accumulation of atherogenic remnants has been described in
patients with type 2 diabetes mellitus (T2DM), familial combined hyperlipidaemia (FCH),
familial hypercholesterolaemia (FH) and coronary artery disease (CAD). Scarce data are
available on fasting plasma apolipoprotein (apo) B48 levels in relation to these conditions and
atherosclerosis.
DESIGN: Treated patients with FCH (18), FH (20), T2DM (26), CAD (65), T2DM with CAD (T2DM/
CAD) (28) and 33 healthy controls were included. Intima-media thickness (IMT) measurements were carried out to investigate subclinical atherosclerosis.
RESULTS: LDL-C and total apoB were lowest in patients with T2DM/CAD owing to the more
frequent use of lipid-lowering medication. Fasting plasma apoB48 was mg/L) and T2DM/CAD
1·50 ± elevated in patients with FCH (11·38 mg/L) compared with the other groups (anova, P

P<0·20, = 0·001), whereas total apoB was not associated with IMT (r 0·12). = P
CONCLUSIONS: ApoB48 concentrations are highest in patients with FCH and in atherosclerotic subjects with T2DM. In patients not using statins, the surrogate atherosclerosis marker
IMT correlates best with apoB48, suggesting that fasting apoB48 may help to detect subjects
at risk.

Sunitinib-associated pseudothrombocytopenia induced by IgM antibody.
Albersen A, Porcelijn L, Schilders J, Zuetenhorst H, Njo TL, Hamberg P.
Platelets. 2012 Oct 15.
PMID: 23066976.
BACKGROUND: Thrombocytopenia is a well-documented adverse reaction of sunitinib.
Thrombocytopenia was observed in a patient with metastatic renal clear-cell carcinoma
undergoing sunitinib treatment. Platelet count in an ethylenediaminetetraacetic acid (EDTA)
sample was 19 × 10(9)/l. To exclude pseudothrombocytopenia (PTCP), a platelet count in
citrate-anticoagulated blood was performed, showing a platelet count of 6 × 10(9)/l. Due to
the apparent thrombocytopenia, the patient received platelet concentrates. Subsequent
analyses revealed PTCP whereby platelet clumping was most abundant in citrate - followed
by EDTA- and heparin-anticoagulated blood samples. This effect was partially reversed after
placing blood samples at 37°C. The IgM antiplatelet autoantibodies responsible for in vitro
agglutination are temperature and multianticoagulant dependent and did not react to
amikacin pre-supplementation. Remarkably, the antibody revealed specificity to platelet
antigens other than GPIIb/IIIa, GPIb/IX, GPIa/IIa, GPIV, and GPV. After 16 days of discontinuing sunitinib, no PTCP and no platelet reactive antibodies could be detected. We report a
case of PTCP with clear time-relation with sunitinib, strongly suggesting the mechanism to
be sunitinib dependent. Since this finding has not been described before, non-recognition
of PTCP during sunitinib treatment might lead to dose reduction or unwarranted therapy.

Antineutrophil cytoplasmic autoantibodies: how are they detected and

Exposure to silica dust has been examined as a possible risk factor for autoimmune
diseases, including scleroderma, rheumatoid arthritis and systemic lupus erythematosus.
Since CTLA-4 [CD152] and PD-1 [CD279] are important for the maintenance of peripheral
tolerance by regulating T cell responsiveness, we evaluated the expression of these
molecules on the surface of CD4 and CD8 T cells, as well as single nucleotide polymorphisms (SNP) in CTLA-4 and PDCD1 genes, of 70 silica-exposed workers and 30 non-exposed, age-, ethnically- and sex-matched controls. Expression of CTLA-4 was significantly
(P<0.05) reduced in CD4 T cells of exposed individuals [median=0.1% and interquartile
range, IQR 0.0-0.1% (exposed), median=0.20%, IQR 0.0-0.4% (control)]. Also the expression
of PD-1 was significantly (P<0.0001) reduced in both CD4 [median=0.9%, IQR 0.4-2.3%
(exposed), median=5.7%, IQR 1.4-13.3% (control)] and CD8 T cells [median=0.9%, IQR
0.3-1.9% (exposed), median=5.0%, IQR 3.4-8.9% (control)]. The study of polymorphisms
demonstrated a lower frequency of the A allele in the analysis of the PD1.3 SNP in the
exposed group, which might be associated with the lower expression of PD-1 on the surface
of CD4 T cells. Our findings provide evidence for the association of silica exposure and the
maintenance of self-tolerance, i.e., the susceptibility to autoimmune disorders.

Concerns About Exercise Are Related to Walk Test Results in Pulmonary Rehabilitation for Patients with COPD.
Fischer MJ, Scharloo M, Abbink J, van ‘t Hul A, van Ranst D, Rudolphus A, Weinman J,
Rabe KF, Kaptein AA.
Int J Behav Med. 2012, 19:39–47. PMID: 21080250.
WETENSCHAPPELIJK JAARVERSLAG 2012
BACKGROUND: Although international guidelines on pulmonary rehabilitation acknowledge
that psychological factors contribute to exercise intolerance in patients with chronic
obstructive pulmonary disease (COPD), the few empirical studies investigating this
association have found inconsistent results.
PURPOSE: The purpose of this study is to investigate whether negative affect and beliefs
about exercise of patients with COPD would be related to baseline 6-min walk (6-MW) test
results in a pulmonary rehabilitation setting, after correction for physical variables (sex,
age, height, weight, and lung function). A second aim was to examine whether patients’
beliefs are associated with treatment outcomes, as measured by an improvement in 6-MW
distance.
METHOD: A 12-week pulmonary rehabilitation program was completed by 166 patients.
Beliefs (perceived necessity and concerns) about exercise and negative affect were
assessed by a questionnaire. Clinical data were obtained from medical records.
RESULTS: Baseline 6-MW distance was positively related to younger age, male gender,
better pulmonary function, and having fewer concerns about exercise. After rehabilitation,
patients had increased their walk distance by 12% (32 m), on average. Baseline physiological and psychological variables were unrelated to patients’ response to treatment (increase
in walk distance). However, subgroup analysis showed that for patients with mild to
moderate airflow obstruction, concerns about exercise were negatively related to response
to treatment. CONCLUSION: We conclude that patients’ beliefs about the negative consequences of exercise are associated with baseline 6-MW test performance and response to
treatment for patients with mild to moderate COPD. We recommend that patients’ concerns
about exercise are discussed and, if necessary, corrected during the intake phase.

Obesity is associated with local T-cell abnormalities in adipose tissue. Systemic obesityrelated abnormalities in the peripheral blood T-cell compartment are not well defined.
In this study, we investigated the peripheral blood T-cell compartment of morbidly obese
and lean subjects. We determined all major T-cell subpopulations via six-color flow
cytometry, including CD8+ and CD4+ T cells, CD4+ T-helper (Th) subpopulations, and
natural CD4+CD25+FoxP3+ T-regulatory (Treg) cells. Moreover, molecular analyses to
assess thymic output, T-cell proliferation (T-cell receptor excision circle analysis), and T-cell
receptor-β (TCRB) repertoire (GeneScan analysis) were performed. In addition, we
determined plasma levels of proinflammatory cytokines and cytokines associated with
LONGZIEKTEN
Th subpopulations and T-cell proliferation. Morbidly obese subjects had a selective
increase in peripheral blood CD4+ naive, memory, natural CD4+CD25+FoxP3+ Treg, and
Th2 T cells, whereas CD8+ T cells were normal. CD4+ and CD8+ T-cell proliferation was
increased, whereas the TCRB repertoire was not significantly altered. Plasma levels of
cytokines CCL5 and IL-7 were elevated. CD4+ T-cell numbers correlated positively with
fasting insulin levels. The peripheral blood T-cell compartment of morbidly obese subjects
is characterized by increased homeostatic T-cell proliferation to which cytokines IL-7 and
CCL5, among others, might contribute. This is associated with increased CD4+ T cells,
with skewing toward a Treg- and Th2-dominated.
ABSTRACT BACKGROUND: Omalizumab, licensed for patients with uncontrolled persistent
allergic (IgE mediated) asthma, was found to be cost-effective based upon its clinical trial
data. Observational studies have been undertaken to determine the real life outcomes of
using omalizumab in the community. Objective: To determine the cost-effectiveness of
omalizumab based upon observational data from the Netherlands and compare to its
cost-effectiveness using clinical trial data. Methods: An observational study (eXpeRience)
recruited allergic asthma patients eligible for Omalizumab therapy and followed them
while on treatment. At 1 year, data from the Dutch patients enrolled in eXpeRience were
examined to estimate the number of exacerbations and resource use while on omalizumab therapy compared to the year prior to omalizumab use. Observational data were
used in a Markov model to calculate the lifetime cost-effectiveness ratios. Results: In the
1 year prior to omalizumab therapy the per-person rate of exacerbations was 3.39
compared to 1.07 in the year taking omalizumab. The discounted incremental lifetime
additional costs for omalizumab were €55,865 for 1.46 additional quality-adjusted life
years (QALY), resulting in €38,371/QALY. Using the INNOVATE clinical trial outcomes and
current resource use, the prior ratio was €34,911/QALY, similar to the observational ratio.
As in all observational studies, the main limitation is obtaining complete and accurate
data. Patients with missing exacerbation or response data were excluded from this
analysis. Conclusion: Non-clinical trial experience with omalizumab supported the finding
of fewer exacerbations in the allergic asthma population while treated with omalizumab,
and therapy was found to continue to have an attractive cost-effectiveness ratio.

The global rating scale in clinical practice.
BACKGROUND: The Global Rating Scale is an endoscopy quality assurance programme,
successfully implemented in England. It remains uncertain whether it is applicable in
another health care setting.
AIM: To assess the applicability of the Global Rating Scale as benchmark tool in an
international context.
METHODS: Eleven Dutch endoscopy departments were included for a Global Rating
Scale-census, performed as a cross-sectional evaluation, July 2010. Two Global Rating
Scale-dimensions - ‘clinical quality’ and ‘patient experience’ - were assessed across six
items using a range of levels: from level-D (basic) to level-A (excellent). Construct
validity was assessed by comparing department-specific colonoscopy audit data to
GRS-levels.
RESULTS: For ‘clinical quality’, variable scores were achieved in items ‘safety’ (9%=B,
27%=C, 64%=D) and ‘communication’ (46%=A, 18%=C, 36%=D). All departments achieved
a basic score in ‘quality’ (100%=D). For ‘patient experience’, variable scores were achieved
in ‘timeliness’ (18%=A, 9%=B, 73%=D) and ‘booking-choice’ (36%=B, 46%=C, 18%=D). All
departments achieved basic scores in ‘equality’ (100%=D). Departments obtaining level-C
or above in ‘information’, ‘comfort’, ‘communication’, ‘timeliness’ and ‘aftercare’, achieved
significantly better audit outcomes compared to those obtaining level-D (p<0.05).
CONCLUSION: The Global Rating Scale is appropriate to use outside England. There was
significant variance across departments in dimensions. Most Global Rating Scale-levels
were in line with departments’ audit outcomes, indicating construct validity.

METHODS: Consecutive outpatients undergoing colonoscopy were asked for permission to
be called 30 days after their procedure. A standard telephone interview was developed to
assess the occurrence of (i) major adverse events (hospital visit required), (ii) minor
adverse events, and (iii) days missed from work. Adverse events were further categorized in
definite-, possible-, and unrelated adverse events. Patients were contacted between
January 2010 and September 2010.
RESULTS: Out of a total of 1,528 patients who underwent colonoscopy and gave permission
for a telephone call, 1,144 patients were contacted (response: 75%), 49% were male, the
mean age was 59 years (s.d.: 14). Thirty-four patients (3%) reported major adverse events.
These were definite-related in nine (1%) patients, possible-related in 6 (1%), and unrelated
in 19 patients (2%). Minor adverse events were reported by 466 patients (41%). These were
definite-related in 336 patients (29%), possible-related in 36 (3%), and unrelated in the
remaining 94 patients (8%). Female gender (odds ratio (OR): 1.5), age <50 years (OR: 1.5),
colonoscopy for colorectal cancer screening/surveillance (OR: 1.6), and fellow-endoscopy
(OR: 1.7) were risk factors for the occurrence of any definite-related adverse event. Patients
who reported definite-related adverse events were significantly less often willing to return
for colonoscopy (81 vs. 88%, P<0.01) and were less often positive about the entire
colonoscopy experience (84 vs. 89%, P=0.04).
CONCLUSIONS: Structured assessment of post-colonoscopy adverse events shows that
these are more common than generally reported. Close to one-third of patients report
definite-related adverse events, which are major in close to 1 in 100 patients. The occurrence of adverse events does have an impact on the willingness to return for colonoscopy.

BACKGROUND
AIMS: The efficacy of colorectal cancer screening programs depends on the rate of
attendance at surveillance colonoscopy examinations. Increasing patients’ awareness
about the importance of surveillance might improve attendance, but it is not clear how
much they know about their follow-up recommendations. We assessed the awareness of
patients with adenomas about their surveillance recommendations.
METHODS: Ten endoscopy departments provided access to their colonoscopy database for
quality assurance; 2 datasets were obtained. We analyzed data from 4000 colonoscopies
(400 per department) performed on patients with adenomas. All the patients were mailed a
survey to determine how much information they had about their colonoscopy results and
their follow-up recommendations. Data from 549 patients were included in the analysis. We
also assessed surveillance attendance among 500 patients (50 per department) who had
adenomas removed.
RESULTS: Of the patients analyzed, 85% recalled retrieval of polyps during their colonoscopy, and 85% recalled whether they needed surveillance or not. The indication for
surveillance was recalled by 69% of patients (range between departments, 55%-83%;
P < .01). Factors that were associated with awareness of recommendations were younger
age (odds ratio [OR], 1.06; 95% confidence interval [CI], 1.06-1.09), treatment by a
MDL
gastroenterologist (OR, 5.53; 95% CI, 3.28-9.32), and presence of 3 or more adenomas
(OR, 2.97; 95% CI, 1.29-6.85). Attendance among patients with adenomas varied among
departments, from 60% to 89% (P < .01), and was not associated with awareness of
patients about their recommendations per department (P = .59).
CONCLUSIONS: Not enough patients (only 85%) who receive colonoscopies are aware of
their results or surveillance recommendations. Although awareness of findings and
recommendations did not correlate with follow-up attendance, patients should be better
informed about findings and their need for surveillance.
Quality evaluation of colonoscopy reporting and colonoscopy
perfomance in daily clinical practice.
BACKGROUND: Comprehensive monitoring of colonoscopy quality requires complete and
accurate colonoscopy reporting.
OBJECTIVE: This study aimed to assess the compliance with colonoscopy reporting and to
assess the quality of colonoscopy performance.
DESIGN: Consecutive colonoscopy reports were reviewed by hand. Four hundred reports
were included from each department.
SETTING: Daily clinical practice in 12 Dutch endoscopy departments.
PATIENTS: Consecutive patients undergoing scheduled colonoscopy procedures.
MAIN OUTCOME MEASUREMENTS: Quality of reporting was assessed by using the American
Society for Gastrointestinal Endoscopy criteria for colonoscopy reporting. Quality of
colonoscopy performance was evaluated by using the cecal intubation rate and adenoma
detection rate (ADR).
RESULTS: A total of 4800 colonoscopies were performed by 116 endoscopists: 70% by
gastroenterologists, 16% by gastroenterology fellows, 10% by internists, 3% by nurseendoscopists, and 1% by surgeons. The mean age of the patients was 59 years (standard
deviation 16), and 47% were male. Reports contained information on indication, sedation
practice, and extent of the procedure in more than 90%. Only 62% of the reports mentioned
the quality of bowel preparation (range between departments 7%-100%); photographic
documentation of the cecal landmarks was present in 71% (range 22%-97%). The adjusted
cecal intubation rate was 92% (range 84%-97%). The ADR was 24% (range 13%-32%).
LIMITATIONS: Dependent on reports, no intervention in endoscopic practice. No analysis for
performance per endoscopist.
CONCLUSION: Colonoscopy reporting varied significantly in clinical practice. Colonoscopy
performance met the suggested standards; however, considerable variability between
endoscopy departments was found. The results of this study underline the importance of
the implementation of quality indicators and guidelines. Moreover, by continuous monitoring
of quality parameters, the quality of both colonoscopy reporting and colonoscopy performance can easily be improved.

Small bowel angioedema due to acquired C1 inhibitor deficiency:
a case report and overview.
Oostergo T, Prins G, Schrama YC, Leeuwenburgh I.
Eur J Gastroenterol Hepatol, 2012 Dec 18: Epub.
PMID: 23255023.
Acquired angioedema is a rare disorder caused by an acquired deficiency of C1 inhibitor.
It is characterized by nonpitting, nonpruritic subcutaneous or submucosal edema of the
skin, or of the respiratory or gastrointestinal tract. When localized in the gastrointestinal
tract, it can cause severe abdominal pain, mimicking an acute surgical abdomen, or chronic
recurrent pain of moderate intensity. We report a case of a 48-year-old man presenting with
recurrent episodes of hypotension and abdominal pain. Computed tomography of the
abdomen showed edema of the small bowel. The first determinations of C1 inhibitor level
and activity, measured in a symptom-free period, were normal. Repetition of the laboratory
tests in the acute phase, however, showed a low C1 inhibitor level. Further diagnostic
work-up indicated an acquired C1 inhibitor deficiency caused by a monoclonal gammopathy. He was treated with tranexamic acid as prophylaxis for his frequent attacks and to
date, he has remained symptom free. Acquired C1 inhibitor deficiency is a rare cause of
angioedema and is, among others, related to autoantibodies and abnormal B-cell proliferation, for example monoclonal gammopathy. The diagnosis of acquired C1 inhibitor
deficiency is made on the basis of the medical history and on the level and activity of
plasma C4, C1q, and C1 inhibitor. In case of high suspicion and a normal C1 inhibitor activity,
it is recommended to repeat this test during an angioedema attack. Early diagnosis is
important for the treatment of severe, potentially life-threatening attacks and to start
prophylactic treatment in patients with frequent or severe angioedema attacks.

Achalasia is characterized by esophageal aperistalsis and impaired relaxation of the lower
esophageal sphincter (LES). This contrasts with an insufficient LES, predisposing to
gastro-esophageal reflux and Barrett’s esophagus. The co-incidence of achalasia and BE is
rare. Pneumatic dilatation (PD) may lead to gastro-esophageal reflux, Barrett’s esophagus
development, and esophageal adenocarcinoma.
AIMS: To determine the incidence of Barrett’s esophagus and esophageal adenocarcinoma
in achalasia patients treated with PD.
METHODS: We performed a single-center cohort follow-up study of 331 achalasia patients
treated with PD. Mean follow-up was 8.9 years, consisting of regular esophageal manometry, timed barium esophagram, and endoscopy.
RESULTS: Twenty-eight (8.4 %) patients were diagnosed with Barrett’s esophagus, one at
baseline endoscopy. This corresponds with an annual incidence of Barrett’s esophagus of
1.00 % (95 % CI 0.62-1.37). Hiatal herniation was present in 74 patients and 21 developed
Barrett’s esophagus compared to seven of 257 patients without a hiatal hernia. Statistical
analysis revealed a hazard ratio of 8.04 to develop Barrett’s esophagus if a hiatal hernia was
present. Post-treatment LES pressures were lower in patients with Barrett’s esophagus
than in those without (13.9 vs. 17.4 mmHg; p = 0.03). Two (0.6 %) patients developed
MDL
esophageal adenocarcinoma during follow-up.
CONCLUSIONS: Barrett’s esophagus is incidentally diagnosed in untreated achalasia patients
despite high LES pressures, but is more common after successful treatment, especially in the
presence of hiatal herniation. Patients treated for achalasia should be considered for GERD
treatment and surveillance of development of Barrett’s esophagus, in particular, when they
have low LES pressures and a hiatal herniation.

Bariatric surgery is in general the only effective treatment for morbid obesity. Bariatric
surgery is frequently associated with vitamin and mineral deficiencies which may lead to
neurological and other symptoms. We describe a case of severe vitamin B1 (thiamine)
deficiency.
CASE DESCRIPTION: A 49-year-old man visited the emergency department with acute
confusion, muscle weakness in arms and legs and visual impairment after a period of
dysphagia and recurrent vomiting. Four months earlier, he had had bariatric gastric sleeve
surgery for morbid obesity. Laboratory tests demonstrated that he had vitamin B1
deficiency, in view of which the diagnosis of beriberi and Wernicke encephalopathy was
made. Despite normalisation of the vitamin B1 concentration following intravenous
supplementation, the muscle strength hardly recovered and the patient developed Korsakov
syndrome.
CONCLUSION: For this deficiency there is no other treatment than vitamin B1 supplementation. Timely recognition of vitamin deficiencies and pro-active supplementation are
essential in order to prevent serious complications following bariatric surgery.
Common variants at 12q14 and 12q24 are associated with
hippocampal volume.
Aging is associated with reductions in hippocampal volume that are accelerated by
Alzheimer’s disease and vascular risk factors. Our genome-wide association study (GWAS)
of dementia-free persons (n = 9,232) identified 46 SNPs at four loci with P values of <4.0 ×
10(-7). In two additional samples (n = 2,318), associations were replicated at 12q14 within
MSRB3-WIF1 (discovery and replication; rs17178006; P = 5.3 × 10(-11)) and at 12q24 near
HRK-FBXW8 (rs7294919; P = 2.9 × 10(-11)). Remaining associations included one SNP at
2q24 within DPP4 (rs6741949; P = 2.9 × 10(-7)) and nine SNPs at 9p33 within ASTN2
(rs7852872; P = 1.0 × 10(-7)); along with the chromosome 12 associations, these loci were
also associated with hippocampal volume (P < 0.05) in a third younger, more heterogeneous
sample (n = 7,794). The SNP in ASTN2 also showed suggestive association with decline in
cognition in a largely independent sample (n = 1,563). These associations implicate genes
related to apoptosis (HRK), development (WIF1), oxidative stress (MSR3B), ubiquitination
(FBXW8) and neuronal migration (ASTN2), as well as enzymes targeted by new diabetes
medications (DPP4), indicating new genetic influences on hippocampal size and possibly
the risk of cognitive decline and dementia.

The thyroid hormone receptor alpha locus and white matter lesions:
a role for the clock gene REV-ERBα.

PMID: 23083441.
Thyroid disorders are associated with an increased risk of cognitive impairment and
Alzheimer’s disease. Both small vessel disease and neurodegeneration have a role in the
pathogenesis of cognitive impairment and Alzheimer’s disease. Thyroid hormone receptor
alpha (TRα) is the predominant TR in brain. The circadian clock gene REV-ERBα overlaps with
the TRα gene and interferes with TRα expression. Limited data are available on the role of the
TRα/REV-ERBα locus in small vessel disease and neurodegeneration. We therefore studied
genetic variation in the TRα/REV-ERBα locus in relation to brain imaging data, as early
markers for small vessel disease and neurodegeneration.
Fifteen polymorphisms, covering the TRα/REV-ERBα locus, were studied in relation to white
matter lesion (WML), total brain, and hippocampal volumes in the Rotterdam Study I (RS-I,
n=454). Associations that remained significant after multiple testing correction were
subsequently studied in an independent population for replication (RS-II, n=607).
No associations with total brain or hippocampal volumes were detected. A haplotype block in
REV-ERBα was associated with WML volumes in RS-I. Absence of this haplotype was
associated with larger WML volumes in women (0.38%±0.18% [β±SE], p=0.007), but not in
men (0.04%±0.11%, p=0.24), which was replicated in RS-II (women: 0.15%±0.05%, p=0.04;
men: 0.05%±0.07%, p=0.80). Meta-analysis of the two populations showed that women
lacking this haplotype have a 1.9 times larger WML volume (p=0.001).
Our results suggest a role for REV-ERBα in the pathogenesis of WMLs.

BACKGROUND: Stroke is the main cause of disability in high income countries and ranks
second as a cause of death worldwide. Infections occur frequently after stroke and may
adversely affect outcome. Preventive antibiotic therapy in the acute phase of stroke may
reduce infections and improve outcome.
OBJECTIVES: 1. To assess whether preventive antibiotic therapy in patients with acute stroke
reduces the risk of dependency and death at follow-up. 2. To assess whether preventive
antibiotic therapy in patients with acute stroke reduces infection rate.
SEARCH METHODS: We searched the Cochrane Stroke Group’s Trials Register (October 2010);
The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010,
Issue 3); MEDLINE (1950 to October 2010) and EMBASE (1980 to October 2010). In an effort
to identify further published, unpublished and ongoing trials we searched trials and research
registers, scanned reference lists and contacted authors, colleagues and researchers in the
field.
NEUROLOGIE
SELECTION CRITERIA: Randomised controlled trials (RCTs) of preventive antibiotic therapy
versus control (placebo or open control) in patients with acute ischaemic or haemorrhagic stroke.
DATA COLLECTION AND ANALYSIS: Two authors independently selected articles and
performed data extraction; we discussed and resolved discrepancies in a consensus
meeting with a third observer. We contacted the study authors to obtain missing data when
required. An independent observer assessed methodological quality. We calculated relative
risks (RRs) for dichotomous outcomes, assessed heterogeneity amongst included studies
and performed subgroup analyses on study quality.
MAIN RESULTS: We included five studies involving 506 patients. Study population, study
design, type of antibiotic and definition of infection differed considerably. The number of
patients who died in the preventive antibiotic group was non-significantly reduced (33/248
(13%) versus 38/258 (15%), RR 0.85, 95% confidence interval (CI) 0.47 to 1.51); the
number of dependent patients in the preventive antibiotic therapy group was also nonsignificantly reduced (97/208 (47%) versus 127/208 (61%), RR 0.67, 95% CI 0.32 to 1.43).
Preventive antibiotic therapy did reduce the incidence of infections in patients with acute
stroke from 36% to 22% (36/166 (22%) versus 61/169 (36%), RR 0.58, 95% CI 0.43 to
0.79). No major side-effects of preventive antibiotic therapy were reported.
AUTHORS’ CONCLUSIONS: In this meta-analysis, preventive antibiotic therapy seemed to
reduce the risk of infection, but did not reduce the number of dependent or deceased
patients. However, the included studies were small and heterogeneous. Large randomised
trials are urgently needed.

Genome-wide studies may lead to the discovery of genetic variants of potential clinical
importance beyond the aims of the study. We performed single nucleotide polymorphism
array analysis in a boy with oculocutaneous albinism to identify copy-neutral regions of
homozygosity harboring genes involved in melanin biosynthesis. An unanticipated
homozygous deletion of chromosome 5p13.3 was discovered, encompassing not only the
OCA gene SLC45A2, but also four additional genes. This led to an unexpected presymptomatic diagnosis of alpha-methylacyl-CoA racemase deficiency in the same patient.

WETENSCHAPPELIJK JAARVERSLAG 2012
Age is the most prominent predisposition for development of osteoarthritis (OA).
Age-related changes of articular cartilage are likely to play a role. Advanced glycation
endproducts (AGEs) accumulate in cartilage matrix with increasing age and adversely affect
the biomechanical properties of the cartilage matrix and influence chondrocyte activity.
In clinical studies AGEing of cartilage and its relation to actual cartilage damage can only
be measured by surrogate markers (e.g., serum, skin or urine AGE levels and imaging or
biochemical markers of cartilage damage). In this study actual cartilage AGE levels were
directly related to actual cartilage damage by use of cartilage obtained at joint replacement
surgery.
METHODS: Cartilage and urine samples were obtained from 69 patients undergoing total
knee replacement. Samples were analyzed for pentosidine as marker of AGE.
Cartilage damage was evaluated macroscopically, histologically, and biochemically.
RESULTS: Cartilage and urine pentosidine both increased with increasing age. The higher the
macroscopic, histological, and biochemical cartilage damage the lower the cartilage
pentosidine levels were. In multiple regression analysis age is not found to be a confounder.
CONCLUSION: There is an inverse relation between cartilage AGEs and actual cartilage
damage in end-stage OA. This is likely due to ongoing (ineffective) increased turnover of
cartilage matrix proteins even in end stage disease.

Induction therapy with a combination of DMARDs is better than
methotrexate monotherapy: first results of the TREACH trial.
de Jong PH, Hazes JMW, Barendregt PJ, Huisman AM, van Zeben D, (et al).
Ann Rheum Dis 2012; Epub 2012 june 7.
PMID: 22679301.
OBJECTIVE: To determine the most effective induction disease-modifying antirheumatic
drug (DMARD) strategy in early rheumatoid arthritis (RA), second to compare one single
dose of intramuscular glucocorticoids (GCs) with daily oral GCs during the induction phase.
METHODS: The 3-month data of a single-blinded clinical trial in patients with recent-onset
arthritis (tREACH) were used. Patients were included who had a high probability (>70%) of
progressing to persistent arthritis, based on the prediction model of Visser. Patients were
randomised into three induction therapy strategies: (A) combination therapy (methotrexate
(MTX) + sulfasalazine + hydroxychloroquine) with GCs intramuscularly; (B) combination
therapy with an oral GC tapering scheme and (C) MTX with oral GCs similar to B. A total of
281 patients were randomly assigned to strategy (A) (n=91), (B) (n=93) or (C) (n=97).
RESULTS: The Disease Activity Score (DAS) after 3 months was lower in patients receiving
initial combination therapy than in those receiving MTX monotherapy (0.39 (0.67 to 0.11,
95% CI)). DAS did not differ between the different GC bridging treatments. After 3 months
50% fewer biological agents were prescribed in the combination therapy groups. Although
the proportion of patients with medication adjustments differed significantly between the
treatment arms, no differences were seen in these adjustments due to adverse events after
stratification for drug. CONCLUSION: Triple DMARD induction therapy is better than MTX
monotherapy in early RA. Furthermore, no differences were seen in medication adjustments
due to adverse events after stratification for drug. Intramuscular and oral GCs are equally
effective as bridging treatments and both can be used.

OBJECTIVES: The Digital Ulcers Outcome (DUO) Registry was designed to describe the
clinical and antibody characteristics, disease course and outcomes of patients with digital
ulcers associated with systemic sclerosis (SSc).
METHODS: The DUO Registry is a European, prospective, multicentre, observational, registry
of SSc patients with ongoing digital ulcer disease, irrespective of treatment regimen. Data
collected included demographics, SSc duration, SSc subset, internal organ manifestations,
autoantibodies, previous and ongoing interventions and complications related to digital
ulcers.
RESULTS: Up to 19 November 2010 a total of 2439 patients had enrolled into the registry.
Most were classified as either limited cutaneous SSc (lcSSc; 52.2%) or diffuse cutaneous
SSc (dcSSc; 36.9%). Digital ulcers developed earlier in patients with dcSSc compared with
lcSSc. Almost all patients (95.7%) tested positive for antinuclear antibodies, 45.2% for
anti-scleroderma-70 and 43.6% for anticentromere antibodies (ACA). The first digital ulcer
REUMATOLOGIE
in the anti-scleroderma-70-positive patient cohort occurred approximately 5 years earlier
than the ACA-positive patient group.
CONCLUSIONS: This study provides data from a large cohort of SSc patients with a history of
digital ulcers. The early occurrence and high frequency of digital ulcer complications are
especially seen in patients with dcSSc and/or anti-scleroderma-70 antibodies.
Treatment decisions and related costs differ significantly depending on
the choice of a disease activity index, in rheumatoid arthritis according
to 1987 and 2010 classification criteria.
OBJECTIVE: To evaluate the therapeutic and economic consequences of various disease
activity indices (DAIs) in RA according to 1987 and 2010 criteria.
METHODS: Data on disease activity states from all sustained visits were assessed from all
patients who participate in the treatment in the Rotterdam Early Arthritis Cohort (tREACH)
study, a stratified randomized trial to evaluate different treatment strategies in patients
with a symptom duration of <1 year. Frequencies of treatment adaptations, based upon
exclusive thresholds of various DAIs, were visualized in reclassification tables. The
Stuart-Maxwell test was applied to analyse any significant differences between treatment
decisions according to the different DAIs. Simulated annual median medication costs were
estimated using the tREACH medication protocol with standard national costs.
RESULTS: DAIs perform similar in RA according to 1987 and 2010 criteria. A total of 1104
DASs per DAI were available from 296 patients. DAIs differ significantly, compared with
DASs, in classifying a patient’s disease state. Consequently, treatment intensifications
occur more frequently with SDAI, CDAI and DAS-28 usage, compared with DAS. Tapering
treatment occurs less frequently with SDAI and CDAI and more frequently with DAS-28
usage. Simulated annual median medication costs are significantly higher if DAS-28, SDAI
and CDAI are used compared with DAS usage.
CONCLUSION: Usage of various DAIs in a single patient leads to inconsistent disease state
categorizations. Consequently, these inconsistencies significantly influence therapeutic
decisions and accompanying costs. As DAI usage is imperative to uphold current European
League Against Rheumatology (EULAR) treatment recommendations, physicians should
consider these therapeutic and economic consequences before choosing a particular DAI.
In vitro glucocorticoïd sensitivity is associated with clinical glucocorticoïd
therapy outcome in rheumatoid arthritis.

INTRODUCTION: Genetic and disease-related factors give rise to a wide spectrum of
glucocorticoid (GC) sensitivity in rheumatoid arthritis (RA). In clinical practice, GC treatment
is not adapted to these differences in GC sensitivity. In vitro assessment of GC sensitivity
before the start of therapy could allow more individualized GC therapy. The aim of the study
was to investigate the association between in vitro and in vivo GC sensitivity in RA.

METHODS: Thirty-eight early and 37 established RA patients were prospectively studied.
In vitro GC sensitivity was assessed with dexamethasone-induced effects on interleukin-2
(IL-2) and glucocorticoid-induced leucine zipper (GILZ) messenger RNA expression in
peripheral blood mononuclear cells (PBMCs). A whole-cell dexamethasone-binding assay
was used to measure number and affinity (1/KD) of glucocorticoid receptors (GRs).In vivo
GC sensitivity was determined by measuring the disease activity score (DAS) and health
assessment questionnaire disability index (HAQ-DI) score before and after 2 weeks of
standardized GC treatment.
RESULTS: GR number was positively correlated with improvement in DAS. IL-2-EC50 and
GILZ-EC50 values both had weak near-significant correlations with clinical improvement in
DAS in intramuscularly treated patients only. HAQ responders had lower GILZ-EC50 values
and higher GR number and KD.
CONCLUSIONS: Baseline cellular in vitro glucocorticoid sensitivity is modestly associated
with in vivo improvement in DAS and HAQ-DI score after GC bridging therapy in RA. Further
studies are needed to evaluate whether in vitro GC sensitivity may support the development
of tailor-made GC therapy in RA.
Brief Report: to squeeze or not to squeeze, that is the question! Optimizing

OBJECTIVE: To optimize use of the Disease Activity Score in 28 joints (DAS28) in early
rheumatoid arthritis (RA) by adding the “squeeze test” of forefeet.METHODS: The squeeze
test is used to examine bilateral compression pain (BCP) across the metatarsophalangeal
(MTP) joints. For this study, data for patients participating in the Treatment in the Rotterdam Early Arthritis Cohort study, an ongoing clinical trial that evaluates different induction
therapies in patients with early RA, were randomly divided into 2 subsets. In subset 1 (149
patients and 819 disease activity assessments), the mathematical function of the
DAS28-squeeze was constructed using a linear regression model with the DAS as the
dependent variable and the DAS28 and squeeze test as the independent variables. A
DAS28-BCP disease state was also constructed, in which DAS28 disease state categorizations were upgraded one state if the result of the squeeze test was positive. In subset 2 (153
patients and 754 assessments), concordance in disease states between the DAS28,
DAS28-squeeze, and DAS28-BCP disease states was compared, using both the DAS and
Boolean-defined remission criteria as reference.RESULTS: Agreement between the DAS and
the DAS28-squeeze (82%) was significantly higher than agreement between the DAS and
the DAS28 (76%). When we assessed the group of patients who had arthritis of the forefeet
only (22 patients and 46 assessments), overall agreement between the DAS and the DAS28
was 40%, while agreement between the DAS and the DAS28-squeeze was 59% and that
between the DAS and the DAS28-BCP disease state was 65%. Furthermore, the specificities
of the DAS28-squeeze and the DAS28-BCP (80% and 81%, respectively) were higher than
that of the DAS28 (76%), while the sensitivities of the DAS28, DAS28-squeeze, and
DAS28-BCP to identify true remission according to the Boolean criteria were 88%, 87%, and
81%, respectively.CONCLUSION: Adding the squeeze test of forefeet to the DAS28 has value
for dependably classifying the disease state in patients with early RA.

Serum adipokines in osteoarthritis; comparison with controls and
relationship with local parameters of synovial inflammation and cartilage
damage.
Huisman AM, de Boer TN, van Spil WE, Polak AA, Bijlsma JW, Lafeber FP, Mastbergen SC.
Osteoarthritis Cartilage 2012 Aug;20(8):846-53.
PMID:22595228.
OBJECTIVE: Adipose tissue is an endocrine tissue releasing adipokines suggested to be
involved in the pathogenesis of osteoarthritis (OA). Nevertheless, their relative contribution
and exact mechanisms are still ambiguous. The aim of this study is to compare serum
adipokine levels between end-stage knee OA patients and controls and to relate these
serum levels to local parameters of cartilage damage and synovial inflammation.
METHODS: Serum was collected from 172 severe knee OA patients, shortly before total knee
replacement (TKR) surgery and from 132 controls without radiographic knee OA [Kellgren &
Lawrence (K&L) = 0]. Serum adiponectin, leptin, and resistin levels were measured by
enzyme-linked immunosorbent assay (ELISA). Cartilage and synovial tissue were collected
at TKR surgery and assessed for cartilage degeneration and synovial inflammation by
histochemistry and biochemical analyses. RESULTS: The adipokine levels were all distinctly
higher in OA patients as compared to controls. Especially adiponectin and leptin were
associated with female gender (stand beta = 0.239 and 0.467, respectively, P < 0.001) and
body mass index (BMI) (stand beta = -0.189 and 0.396, respectively, P < 0.001). No
associations between serum levels of adipokines and cartilage damage (histochemistry,
proteoglycan content) were found whereas weak but positive associations with synovial
inflammation were found [adiponectin and interleukin-1β (IL-1β), stand beta = 0.172, P =
0.02; resistin and histology, stand beta = 0.183, P = 0.034, adjusted for demographics].
CONCLUSION: This study suggests an important involvement of adipokines in OA patients
considering their high serum levels compared to controls. Associations of systemic
adipokines with local synovial tissue inflammation were found, although not represented by
similar relations with cartilage damage, suggesting that adipokines are of relevance in the
inflammatory component of OA.

Extravasation of intravesical chemotherapy for non-muscle-invasive
bladder cancer.
Mertens LS, Meinhardt W, Rier WB, Nooter RI, Horenblas S.
Urol Int. 2012; 89:332-6. PMID: 22965138.
PURPOSE: To report our experience with symptomatic extravasation of intravesical
chemotherapy administered within 24 h after transurethral resection (TUR) over the past
10 years. METHODS: We identified all consecutive patients who presented with symptomatic
extravasation of intravesical chemotherapy following TUR between 2001 and 2011. We
assessed the severity of the postoperative complications using the modified Clavien
system.
RESULTS: We identified 9 patients (mean age 59, range 40-76 years) with symptomatic
extravasation. One patient had grade II, 2 had grade IIIa, and 5 patients had grade IIIb
complications according to the Clavien system. Surgery was needed in 6 of 9 patients.
One required ICU management (Clavien IV). No patients died in the postoperative course.
CONCLUSION: Extravasation can cause severe complications and diagnosis is often
protracted. Considering the growing practice of immediate intravesical instillations, the
number of patients with symptomatic extravasation is expected to rise. An increased
awareness of this possible complication is warranted.

BACKGROUND: Overdiagnosis and subsequent overtreatment are important side effects of
screening for, and early detection of, prostate cancer (PCa). Active surveillance (AS) is of
growing interest as an alternative to radical treatment of low-risk PCa.OBJECTIVE: To
update our experience in the largest worldwide prospective AS cohort.DESIGN, SETTING, AND
PARTICIPANTS: Eligible patients had clinical stage T1/T2 PCa, prostate-specific antigen
(PSA) ≤10 ng/ml, PSA density <0.2 ng/ml per milliliter, one or two positive biopsy cores, and
Gleason score ≤6. PSA was measured every 3-6 mo, and volume-based repeat biopsies
were scheduled after 1, 4, and 7 yr. Reclassification was defined as more than two positive
cores or Gleason >6 at repeat biopsy. Recommendation for treatment was triggered in case
of PSA doubling time <3 yr or reclassification. OUTCOME MEASUREMENTS AND STATISTICAL
ANALYSIS: Multivariate regression analysis was used to evaluate predictors for reclassification at repeat biopsy. Active therapy-free survival (ATFS) was assessed with a Kaplan-Meier
analysis, and Cox regression was used to evaluate the association of clinical characteristics
with active therapy over time.RESULTS AND LIMITATIONS: In total, 2494 patients were
included and followed for a median of 1.6 yr. One or more repeat biopsies were performed in
1480 men, of whom 415 men (28%) showed reclassification. Compliance with the first
repeat biopsy was estimated to be 81%. During follow-up, 527 patients (21.1%) underwent
active therapy. ATFS at 2 yr was 77.3%. The strongest predictors for reclassification and
UROLOGIE
switching to deferred treatment were the number of positive cores (two cores compared
with one core) and PSA density. The disease-specific survival rate was 100%. Follow-up was
too short to draw definitive conclusions about the safety of AS. CONCLUSIONS: Our
short-term data support AS as a feasible strategy to reduce overtreatment. Clinical
characteristics and PSA kinetics during follow-up can be used for risk stratification. Strict
monitoring is even more essential in men with high-risk features to enable timely recognition of potentially aggressive disease and offer curative intervention. Limitations of using
surrogate end points and markers in AS should be recognized. TRIAL REGISTRATION: The
current program is registered at the Dutch Trial Register with ID NTR1718.

Een praktisch ertapenem doseerregime bij hemodialyse patiënten.
INLEIDING: Infecties zijn de tweede doodsoorzaak bij dialysepatiënten en veroorzaken een
kwart van alle sterfgevallen in deze groep. Het behandelen van deze infecties wordt
gecompliceerd door een toenemende prevalentie van resistente gram-negatieve bacteriën,
waardoor het gebruik van reserve antibiotica als carbapenems zal gaan toenemen.
Ertapenem, is een carbapenem antibioticum dat toegediend wordt in een dosering van
1 maal daags 1000 mg intraveneus. Bij een creatinineklaring < 30 ml/min en bij hemodialyse wordt een dosisreductie van 50% geadviseerd. Onze hypothese is dat ertapenem bij
dialysepatiënten toegepast kan worden, gebruikmakend van een intervalverlenging in plaats
van een dosisreductie, waardoor een toediening drie maal per week na afloop van de
dialysesessie mogelijk is.
Vraagstelling: Het doel van dit onderzoek is om de farmacokinetiek van Ertapenem te
beschrijven wanneer dit driemaal per week wordt toegediend na afloop van een hemodialysesessie.
METHODEN: Het onderzoek is uitgevoerd bij 10 infectieuze hemodialysepatiënten in het Sint
Franciscus Gasthuis. De minimale inhibitoire concentratie (MIC) werd voor alle aanwezige
bacteriën bepaald. 1 Gram ertapenem werd toegediend na afloop van een dialysesessie.
Bloedmonsters werden afgenomen 45 minuten na inlopen van het infuus, voorafgaand aan
en na afloop van twee aaneensluitende dialysesessies. Ertapenem concentraties werden
bepaald met een gevalideerde LC-MSMS bepaling en de farmacokinetische analyse werd
uitgevoerd met MWPharm.
RESULTATEN: Bij acht van de 10 patiënten is na de behandeling een klinische verbetering
opgetreden. Bij één patiënt was het effect niet te beoordelen i.v.m. een co-infectie met
Stenotrophomonas maltophilia ontstaan tijdens de ertapenem behandeling. Bij één patiënt
is geen klinische verbetering opgetreden. Er was sprake van een volledige occlusie van de
supragenuale femoropopliteale bypass rechts, waardoor mogelijk de doorbloeding ter
plekke van de wondinfectie onvoldoende was. De farmacokinetische parameters in onze
populatie waren verschillend t.o.v. de gerapporteerde waarden bij niet-infectieuze dialysepatiënten. Het verdelingsvolume is hoger (0,16 l/kg vs 0,11 l/kg) en de halfwaardetijd is
verlengd (19,9 uur vs 14,1 uur). De ertapenem dalspiegel op 68 uur was 3,7 mg/l (range 0,5
- 9,6 mg/l) en bleef daarmee boven de individuele MIC (range 0,006 – 0,250 mg/l)
gedurende het gehele doseerinterval.
CONCLUSIE: Dialysepatiënten worden veelvuldig geconfronteerd met infecties waarvoor een
behandeling met antibiotica noodzakelijk is. Veel van deze antibiotica moeten meermaal
daags intraveneus worden toegepast, waardoor een ziekenhuisopname of het inzetten van
de thuiszorg noodzakelijk is. Ertapenem geeft, in het voorgestelde doseerregime, een
concentratie boven MIC gedurende het gehele doseerinterval. Met dit onderzoek tonen wij
aan dat ertapenem toegepast kan worden in een praktisch driemaal wekelijks doseerregime
na afloop van een hemodialysesessie, waardoor de behandeling aansluit rondom de al
bestaande logistiek en verzorging van de patiënt.

INTRODUCTION: Dramatically increasing health care costs are pushing hospitals and
insurance companies to emphasize outpatient management and to decrease length of
hospitalization. We hypothesize that the minimally injured trauma patients, instead of
admission or a period of observation, can be discharged after primary and secondary
surveys at the emergency department. Tertiary survey can take place the next day at the
emergency room or at the surgical outpatient clinic, done by either a physician or a trained
nurse practitioner.
METHODS: The institutional review board approved this study as a retrospective data
collection study; as such informed consent was not required. The registry was queried for
trauma patients undergoing 24-hour observation from January 2010 till December 2010 at
the Sint Franciscus Hospital in Rotterdam, a level II trauma-hospital. For this purpose
patients with a diagnose code (DBC code 294) were gathered and multi-trauma patients
were excluded. Hospital admittance was defined as all trauma patients observed secondary
to: mechanism of injury, lowered state of consciousness, need for further radiographic
evaluation or social reasons. The admission records of all patients were reviewed in order to
register missed injuries, which is defined as injury found during tertiary survey or during
re-examination of radiographic interpretations.
RESULTS: A total of 175 trauma patients were reviewed (table 1). Of these 116 were
admitted to the hospital after primary and secondary survey (table 2). The most common
reasons to admit a patient was for 24-hour observation, pain management and social
reasons. The majority of patients, 99 of 116, were discharged after an observational period
of 24 hours. Pain management and social reasons for elderly patients were the main
reasons for prolonged hospitalization. Two patients were admitted to the intensive care for
observational reasons. No missed injuries were found during tertiary survey in any of the
patients.
DISCUSSION: Our data suggest that in-hospital observation to detect missed injuries, after
thorough primary and secondary survey at the emergency department, does not significantly alter detection of clinically relevant missed injuries. We suggest that minimally
injured trauma patients should be discharged after primary and secondary surveys and that
tertiary survey can take place the following day as an outpatient. This should only be done if
radiologic examinations can be re-interpreted by a radiologist and a traumatologist/
traumasurgeon, as misdiagnosis of radiologic examination is till the biggest cause for
missing injury in trauma patients. Outpatients could then still be treated adequately.

ACHTERGROND: Resultaten van recente publicaties wijzen op een verband tussen vitamine D
deficiëntie en astma bij kinderen, waarbij een lage vitamine D spiegel een risicofactor is voor
ABSTRACTS VOORDRACHTEN
WETENSCHAPSDAG SFG 2012
het ontwikkelen van astma en bijkomend het aantal exacerbaties zou verhogen. Tevens is
bekend dat vitamine D deficiëntie vaak voorkomt bij obesitas. Daarnaast zijn overgewicht en
astma geassocieerd, waarbij tot nu toe de pathofysiologie van deze relatie nog onbekend is.
Vitamine D deficiëntie zou mogelijk ook een rol kunnen spelen bij de associatie tussen
obesitas en astma.
DOEL: Wat is de associatie tussen een laag serum vitamine D spiegel en astma in morbide
obese patiënten.
METHODE: Middels een cross-sectionele studieopzet werd in een cohort van 760 patiënten
met morbide obesitas (BMI>40 kg/m2 of BMI>35 kg/m2 met co- morbiditeit, leeftijd 18-60
jaar) onderzocht of er een associatie bestaat tussen een vitamine D deficiëntie (25(OH)D
concentratie serum<50 nmol/L) en astma, als door een longarts gediagnosticeerd middels
anamnese en longfunctiewaarden; o.a. FEV1, FVC, Tiffeneau<70% en Delta FEV1 > 12%.
RESULTATEN: Drieëntwintig procent (n=173) van het cohort had een door een longarts
gediagnosticeerd astma. Er waren geen significante verschillen in de baseline karakteristieken van de groepen patiënten met en zonder astma, met name ras, BMI, buikomtrek of
gewicht. Er was een trend dat patiënten met astma meer vet (in kg) hadden (70.23 ± 18.4)
dan de groep zonder astma (66.44 ±16.62 , p=0.056). Vitamine D deficiëntie kwam
significant vaker voor in de groep van de patiënten met astma (85%) dan in de groep zonder
astma (72,4%) (p<0.001). Ook de spiegel van vitamine D (nmol/L) was significant lager in
de groep met astma (35.9 ±19.6), dan in de groep zonder astma (39.5 ± 20.8, p=0.044).
CONCLUSIE: In een cohort van mensen met morbide obesitas, hadden patiënten met astma
vaker een vitamine D deficiëntie dan patiënten zonder astma, waarbij er geen verschil was
tussen de groepen in mate van obesitas.
Vitamin D3 improves arterial stiffness and decreases leukocyte activation
postprandially: a pilot study.
INTRODUCTION: The postprandial phase is considered pro-atherogenic in part due to
generalized inflammation by triglyceride-rich lipoproteins. Vitamin D modulates the immune
system and its levels correlate with arterial stiffness and cardiovascular disease, but the
exact mechanisms remains unknown. We investigated if supplementation of vitamin D3
affects arterial stiffness and leukocyte activation postprandially.
Methods: Healthy volunteers underwent two oral fat loading tests (OFLT) and served as their
own control. At 0, 2, 4, 6 and 8 hours the augmentation index (AIx), reflecting vascular
elasticity, was measured by pulse wave analysis together with flow cytometric quantification
of leukocyte activation markers CD11b, CD66b, CD35 and CD36. After completion of the first
OFLT a dose of 100.000 IE of vitamin D3 was administered and a second OFLT was carried
out seven days later.
RESULTS: A total of 12 volunteers were included. 25-Hydroxyvitamin D3 levels rose from
63.0±28.8 mmol/l to 98.5±26.8 mmol/l after vitamin D3 supplementation (P<0.001). The
postprandial triglyceride response remained unaltered. The AIx showed a horizontal
postprandial pattern, but after vitamin D3 supplementation a postprandial decrease in AIx
was found, reflecting increased arterial elasticity. Vitamin D3 significantly reduced the AIx at
T=6 (12.7±15.4% vs 6.9±13.8%, P=0.03) and also the total area under the postprandial AIx

curve (93.1±114.1 au vs 68.6±121.4 au, P=0.04). After vitamin D3, a trend was observed at
the postprandial triglyceride peak (T=4) with reduced expressions of CD11b and CD35 on
neutrophils (24.01±5.3 au vs 21.1±7.1, P=0.06 and 3.0±1.0 vs 2.7±1.0 au, P=0.08,
respectively) and CD11b on monocytes (16.5±2.2 au vs 14.9±2.6 au, P=0.09).
CONCLUSION: Vitamin D3 increases postprandial arterial elasticity in healthy volunteers,
potentially by reducing the expression of endothelial adhesion markers on monocytes and
granulocytes.

INTRODUCTION: In 2006 the bariatric surgical program in our hospital was expanded. We
defined preselection criteria for routine postoperative Intensive Care admission of selected
bariatric patients from risk factors for postoperative complications described in literature.
We retrospectively analysed the data of 546 patients undergoing bariatric surgery to 1)
analyse the value of these preselection criteria, 2) to register the problems encountered in
bariatric patients postoperatively and 3) to identify predisposing factors for postoperative
complications.
METHODS: Basic characteristics, comorbidities and postoperative complications (dehydration, haematoma-bleeding, infectious complications, pulmonary embolism, anastomotic
leakage, gastro-oesophageal reflux/obstruction, respiratory complications, cardiac
complications, other) were evaluated for all patients. In patients admitted to the ICU, the
reason for ICU admittance was recorded: 1) on the basis of preselection criteria, 2) due to
perioperative complications or 3) after re-intervention in a later stage. Furthermore, in each
of these ICU categories, the course on the ICU was identified: no, minor or major actions.
Eventually this resulted in only 6 categories filled with patients. These groups of intensive
care patients were statistically compared to all other patients for basic characteristics and
comorbidities (normal distribution was tested using the Kolmogorov and Smirnov test. A
t-test was used for normally distributed data; a Mann-Whitney test was used for data not
normally distributed. Frequency distributed
data were analysed using a contingency table with a Fisher’s exact test. Statistical
significance was accepted at p < 0.05).
RESULTS: No major actions were needed in patients admitted to our ICU directly postoperative (patients admitted on the basis of preselection criteria or due to perioperative factors).
In these patients pulmonary problems were the most significant problems encountered.
However, no specific actions were needed on the ICU that could not have been performed on
the wards. Bodyweight was significantly higher in patients suffering postoperatively from an
infection, pulmonary embolism or respiratory complications. In patients with a known
bleeding diathesis there were significantly more postoperative bleedings and pulmonary
embolisms. The bleeding diathesis was also significantly increased in the group of ICU
patients admitted to the ICU on the basis of reintervention in a later stage with major
actions on the ICU.
CONCLUSIONS: Preselected criteria formed on the basis of literature are no good predictors
ABSTRACTS VOORDRACHTEN
WETENSCHAPSDAG SFG 2012
for the need of admittance on the ICU postoperative after bariatric surgery. Bariatric surgery
is not a criterion to be admitted to an ICU poster operatively. Provided there is attention for
pulmonary problems on the wards, it is safe for these patients to bypass the ICU, as major
complications do not happen directly postoperatively. Basic pulmonary support on the
wards could be done by providing supplemental oxygen, regular control of breathing
frequency and pulse oximetry as suggested by other authors. Patients with a haemorrhagic
diathesis were more frequently admitted to the ICU on the basis of reintervention in a later
stage with major actions on the ICU.
Sunitinib Associated Thrombocytopenia: Not always what it seems.
INTRODUCTION: Sunitinib is an oral treatment for metastatic renal cell carcinoma (RCC)
which is known to cause thrombocytopenia as an adverse affect. Thrombocytopenia may
lead to dose reduction or therapy termination. Pseudothrombocytopenia (PTCP) is an in
vitro anticoagulant-induced agglutination of platelets by antiplatelet autoantibodies
resulting in a falsely low reported platelet count. This occurs commonly, but not exclusively,
in EDTA-anticoagulated blood. The target antigen is the platelet membrane glycoprotein
(GP) IIb/IIIa complex. Antiplatelet autoantibodies react with hidden antigens on platelet
GPIIb/IIIa which are exposed due to the Ca2+ chelating effect of EDTA. Furthermore,
pre-supplementation of vacutainers with aminoglycosides (amikacin) can prevent
EDTA-dependent PTCP.
CASE REPORT: A 63 year old male patient with metastatic clear-cell RCC, undergoing
sunitinib treatment, was admitted at the emergency department with nausea and fatigue.
No bleeding symptoms were observed. Platelet counts in EDTA- and citrate-anticoagulated
blood samples were 19x10e9/l and 8x10e9/l, respectively. Due to the apparent severe
thrombocytopenia the patient was transfused with three units of platelets. One hour
post-transfusion platelet counts were 43x109/l and 21x109/l in EDTA and citrate, respectively. A heparin blood sample revealed a platelet count of 88x109/l confirming PTCP.
RESULTS: Laboratory investigation revealed that vitro platelet clumping was most abundant
in citrate- (11x10e9/l) followed by EDTA- (15x10e9/l) and heparin (114x10e9/l) anticoagulated blood samples. This effect was partially reversible after placing blood samples at 37
°C. No clumping was observed in blood smears obtained directly from capillary blood
samples, substantiating an in vitro phenomenon. Pre-supplementation with amikacin in
citrate-, EDTA- and heparin vacutainers did not reduce in vitro platelet agglutination. Blood
collection at 37 °C diminished, but did not eliminate, in vitro agglutination in all three
anticoagulants. The indirect platelet immunofluorescence test (iPIFT) revealed strong
platelet reactive IgM antibodies (IgG negative) whereas the monoclonal antibody specific
immobilisation of platelet antigens (MAIPA, IgM and IgG conjugate) was negative for the
GPIIb/IIIa, -Ib/IX and -V. An iPIFT with Glanzmann (GPIIb/IIIa negative) donor platelets also
showed positive IgM antibody reactions, confirming the negative GPIIb/IIIa MAIPA. Sixteen
days after discontinuing sunitinib, no PTCP and no platelet reactive antibodies could be
detected.

ABSTRACTS VOORDRACHTEN
WETENSCHAPSDAG SFG 2012
CONCLUSION: To our knowledge this is the first report of PTCP induced by sunitinib. Platelet
counts showed falsely low levels in EDTA-, citrate- and heparin-anticoagulated blood
samples with a clear time-relation with sunitinib treatment, strongly suggesting the
mechanism to be sunitinib-dependent. The IgM antiplatelet autoantibodies responsible for
in vitro agglutination are multianticoagulant- and temperature-dependent but amikacin
independent. Remarkably, the IgM antibodies demonstrated specificity to platelet antigens
other than GPIIb/IIIa, -Ib/IX and -V. Furthermore, if thrombocytopenia is encountered during
sunitinib treatment, PTCP in EDTA- and in citrate-anticoagulated blood samples should be
excluded before sunitinib dosing is reduced or interrupted.

CASUS BESCHRIJVING: Een 29-jarige vrouw en haar 35-jarige echtgenoot bezochten ons
spreekuur vanwege primaire subfertiliteit. Behoudens een milde ovulatiestoornis op basis
van het polycysteus ovarium syndroom (PCOS) waren er geen afwijkingen en werd de
subfertiliteit als ‘onbegrepen’ geclassificeerd. Na zes intra-uteriene inseminaties was
patiënte niet zwanger en werd overgegaan tot IVF. Ovariële hyperstimulatie vond plaats met
recombinant FSH. Bij de follikelaspiratie werden uit ongeveer 12 follikels van > 15 mm
slechts vijf oöcyten verkregen. Hiervan werden er twee bevrucht. Beide embryo’s werden na
drie dagen in de uterus geplaatst. Negentien dagen na de embryotransfer had patiënte een
positieve zwangerschapstest.
Bij een gecorrigeerde amenorroeduur van 8 weken werd bij transvaginale echoscopie een
vijfling graviditeit vastgesteld (één monoamniotische, monochoriale tweeling en drie
multiamniotische, multichoriale meerlingen). Bij een zwangerschapsduur van 10 weken is
de zwangerschap middels selectieve embryoreductie gereduceerd tot een diamniotische,
dichoriale tweeling zwangerschap. De zwangerschap verliep tot een amenorroeduur van
35 weken ongecompliceerd. Bij 35 weken ontstond er pre-eclampsie en werd patiënte
opgenomen. Bij 36 weken braken de vliezen en is besloten tot een sectio caesarea. Er werd
een gezonde zoon van 2792 gram en een gezonde dochter van 2572 gram geboren.
VRAAGSTELLING: Wat is de kans op spontane conceptie tijdens een IVF behandeling? Is de
kans op een meerlingzwangerschap voldoende reden om coïtus tijdens een IVF behandeling
te ontraden?
METHODE: Systematisch literatuuronderzoek.
RESULTATEN:
- Vergelijkbare case-reports: In pubmed vonden we 4 reports vergelijkbaar met de door ons
beschreven casus. Verondersteld wordt dat de “extra” zwangerschappen ontstaan door
spontane conceptie naast de door IVF ontstane zwangerschappen. Theoretisch kunnen de
“extra” zwangerschappen ook ontstaan door splitsing van de geplaatste embryo’s. Indien
het een monochoriale zwangerschap betreft kan dit middels echoscopie worden herkend.
- Meerlingzwangerschappen na terugplaatsing van één embryo: In een systematic review
(McLernon et al. BMJ, 2011) worden drie meerling-zwangerschappen beschreven na
181 plaatsingen van 1 embryo bij IVF (1.7%). Eén van deze zwangerschappen betreft een
monoamniotische, monochoriale meerling en is vrijwel zeker van het geplaatste embryo
afkomstig. Van de andere twee zwangerschappen is de chorioniciteit niet beschreven.
- Tijdens IVF behandelingen verhoogt coïtus tijdens de dagen rondom de embryoplaatsing
de kans op zwangerschap.
ABSTRACTS VOORDRACHTEN
WETENSCHAPSDAG SFG 2012
- Kans op spontane zwangerschap na staken IVF: De kans op een spontane zwangerschap
na het staken van IVF behandelingen is ongeveer 15%.
CONCLUSIE: Sporadisch is aangetoond dat, naast zwangerschappen ontstaan door IVF, in
dezelfde cyclus “spontane” concepties optreden. Ook is aangetoond dat na het staken van
IVF behandelingen 15% van de paren alsnog zwanger wordt. Deze bevindingen maken het
waarschijnlijk dat een onbekend (beperkt) deel van de zwangerschappen toegeschreven aan
IVF spontane concepties betreft. In tegenstelling tot eerdere auteurs van case reports is het
sporadisch optreden van high–order meerlingen ons inziens geen reden tot het ontraden
van coïtus tijdens de IVF behandeling. Een uitzondering betreft paren waarvoor embryo
reductie een niet bespreekbare optie is.

AIM: The occurrence of anastomotic leakage remains a major concern in rectal surgery.
It is associated with high morbidity, often requires reoperation(s) and represents the most
important cause of treatment induced mortality. It was hypothesized that the use of
anti-traction sutures to support the circular stapled anastomosis may reduce anastomotic
leakage.
METHOD: In a prospective cohort of patients the technique of supportive suturing was
investigated. In 71 patients low anterior resection for rectal cancer was performed. After
excluding patients receiving diverting stoma or inadequate suturing 39 patients received
either laparoscopic or transanal supportive suturing.
RESULTS: Diverting stoma was performed in 17 out of 71 patients (24%). After exclusion of
diverting stoma and partial suturing, 2 of the remaining 49 patients (4%) were diagnosed
with anastomotic leakage. Presacral abscess was found in 2 patients (4%).
CONCLUSION: In this study a low occurrence rate (4%) of anastomotic leakage was noticed
when our technique was used in laparoscopic low anterior resections without diverting
stoma. Considering these promising findings it is important to further investigate the effect
of these methods in a prospective randomized study.

Abstract
Een 57-jarige man werd naar onze polikliniek verwezen in verband met jeukende, niet
genezende wondjes van de hoofdhuid die sinds enkele maanden bestonden. Zijn algemene
voorgeschiedenis vermeldt een transient ischaemic attack waarvoor patiënt aspirine gebruikt.
Zijn dermatologische voorgeschiedenis is blanco. Bij dermatologisch onderzoek zien we op
het behaarde hoofd, verspreid in het gelaat en naast de oren een tiental papels met centrale
hemorrhagische korst en ulceratie. Differentiaaldiagnostisch werd gedacht aan lymfomatoide
papulosis, pityriasis lichenoides et varioliformis acuta, prurigo nodularis en vasculitis. Bij
histopathologisch onderzoek kon de diagnose “langerhanscelhistiocytose” worden gesteld
wegens de aanwezigheid van CD1a en S100 positieve cellen in een zeer dicht dermaal gelegen
infiltraat
Aanvullend onderzoek middels bloedonderzoek, bronchoalveolaire lavage en CT-thorax liet

Small bowel angioedema due to acquired C1 inhibitor deficiency.
Abstract
Abdominal angioedema may present acutely with severe abdominal pain, or as a chronic
recurrent abdominal pain of moderate intensity. Abdominal involvement in angioedema can
be very challenging to diagnose. Angioedema is most frequently a consequence of allergic
etiologies. Non-allergic causes of angioedema are rarer and examples of this are medicationinduced angioedema and angioedema caused by C1 inhibitor deficiency. Here, we report a
case of small bowel angioedema secondary to acquired C1 inhibitor deficiency due to
monoclonal gammopathy.
Acquired C1 inhibitor deficiency is a rare cause of angioedema and is, amongst others, related
to abnormal B-cell proliferation, i.e. monoclonal gammopathy, and autoantibodies. Plasma
C3, C4, C1q and C1 inhibitor levels and activity are used for diagnosis. C1 inhibitor activity can
be normal in a symptom free period and thus can be misleading and delay diagnosis of
angioedema. In case of high suspicion and a normal C1 inhibitor activity, it is recommended
to repeat the test. When frequent or severe attacks occur prophylactic treatment with
antifibrinolytic agents or androgens is necessary.

SSSS: Loslatende huid!
S.T.J Chan, M.C.G van Praag
Afdeling dermatologie
Een 5 jarige jongen werd naar ons doorverwezen in verband met sinds vijf dagen bestaande
rode huiduitslag over het gehele lichaam. Het zou aan de handen en de voeten zijn
begonnen, waarna het zich verder heeft uitgebreid naar de oksels, romp en gelaat. Er is
sprake van een rode jeukende, maar bij aanraking een pijnlijke huiduitslag.
Desloratidine, Hydrocortison zalf FNA en Vaseline Lanette crème zouden geen effect hebben
gehad. Er zou eenmalig sprake zijn geweest van koorts (38,7), maar geen algehele malaise.
Wel was hij af en toe wat hangerig.
De algemene voorgeschiedenis is blanco.
DERMATOLOGISCH ONDERZOEK: In het gelaat, op de romp en extremiteiten diffuus
erythemateuze maculae en bullae. Perioraal tekenen van secundaire impetiginisatie. Geen
afwijkingen op de wangslijmvliezen. Met name in de hals loslating van de huid.
Overig lichamelijk onderzoek Matig zieke indruk.
Hart: S1, S2, geen souffles. Longen: vesiculair ademgeruis, geen bijgeluiden.
Ademhalingsfrequentie: 12 per minuut. Temp. 36,8 ºC.
AANVULLEND ONDERZOEK: Klinische Chemie (kchl): CRP 19 mg/l, Hemoglobine 8.1 mmol/l,
Leucocyten 12.8 10^9/l. Bacteriële kweek van de mondhoek laat zeer veel Staphylococcus
aureus zien.
DIAGNOSE: Op basis van het klinisch beeld en de positieve bacteriële kweek werd de
diagnose staphylococcal scalded skin syndrome gesteld (SSSS) Staphylococcal scalded
skin syndrome (SSSS) is een syndroom dat ontstaat als bacteriën van de stafylococcen
aureus stam toxinen produceren die blaarvorming van de huid veroorzaken en blaarvorming
plaatsvindt op huid zonder tekenen van infectie.
De exfoliatieve toxines A en B, die daarbij vrijkomen, breken desmogleine 1 af in de

Case Report: An Inappropriate AED-shock?
WETENSCHAPPELIJK JAARVERSLAG 2012

BACKGROUND: The use of automated external defibrillators (AED) improves the survival of
adults who suffer from cardiopulmonary arrest. The device can be operated in a simple way
by nonprofessional rescuers and public AED access is currently standard in many countries,
in order to reduce time to defibrillation. Automated external defibrillators detect ventricular
fibrillation (VF) with almost perfect sensitivity and specificity; it will only deliver a shock
when VF is present. We present a case in which an inappropriate shock was delivered in a
conscious patient.
CASE: A 62-year old man was working outside when he experienced sudden chest pain.
Feeling unwell, he layed himself down on the ground. A co-worker applied the AED-patches,
worried about a “heart attack”. At this time the patient was shivering, but conscious and
alert. The AED administered a shock. Readings from the device showed a regular rhythm
(120bpm) followed by progressive interference, mimicking VF, which provoked a shock.
CONCLUSION: Although the shock was technically “appropriate”, it was administered to a
patient with intact circulation, who did not suffer from cardiac arrest. Because the
device-response cannot be altered in cases like this, it is important to instruct the operator
only to apply the AED in an unresponsive patient whom is not breathing normally.

Thrombotic microangiopathy following administration of docetaxel and
zolendronic acid in a patient with castrate refractory prostate cancer
(CRPC).
BACKGROUND: Thrombotic microangiopathy (TMA) is a rare but severe condition, characterised by microangiopathic haemolytic anemia and thrombocytopenia with or without renal
and neurologic abnormalities.
CASE REPORT: In a 66-year old patient with CRPC treatment with docetaxel and zoledronic
acid was initiated. Prior to treatment there was mild anemia and no signs of hemolysis. Two
days after administration of docetaxel and zoledronic acid, he was admitted because of
severe fatigue, and a slightly altered mental state. Blood count showed normocytic anemia
(hemoglobin, 5.7 mmol/l), thrombocytopenia (platelets, 10x10^9/l) and red cell fragmentation (schistocytes) whilst leukocyte-count was normal. Further evaluation showed a
Coombs-negative hemolysis with haptoglobin 0.06 gr/l and renal failure (serum creatinine
471 umol/l).
TMA triggered by docetaxel or zoledronic acid was considered.
Dialysis and plasma infusion was initiated. No plasma exchange was done based on the
assumption that TMA was triggered by treatment and literature is inconclusive with respect
to plasma exchange for drug-induced TMA.
After a few days, the patient refused further treatment and died ten days after admission.
DISCUSSION: TMA is a rare complication in patients with advanced cancer as well chemotherapy-related. Previously a relation with Mitomycin C, Cisplatin and Gemcitabine has been
described. A few cases have been reported on docetaxel (n=2) and zoledronic acid (n=3)
with a suggestive relation to the occurrence of TMA.
In case of multiple triggers, no discriminatory tests are available, although the close timerelation with the administration of docetaxel and zoledronic acid, makes disseminated
cancer a less likely cause.
Level of ADAMTS 13 activity became available after the patient passed away but was normal
(72%). In drug related TMA, less pronounced reductions or normal levels have been noted
what makes it not a good diagnostic tool although low levels can be informative. Testing of
ADAMTS 13 should not be used to confirm the diagnosis.
This is one of the first cases reporting the occurrence of TMA after administration of
docetaxel and zoledronic acid. Oncologist and nephrologists should be aware of this
untoward side effect.

materiaal in combinatie met peristaltiek kunnen zijn. Om deze drukken op te vangen zouden
er steunhechtingen rondom de naad geplaatst kunnen worden. Naar aanleiding van goede
resultaten uit de kliniek is in een experimenteel model de effecten van de steunhechtingen
uitgezocht.
VRAAGSTELLING: Zorgen de steunhechtingen voor een verhoogde “lekdruk” (anastomotic
burst pressure, ABP)?
Methoden: Uit 25 Yorkshire varkens werd binnen 30 minuten na farmacologische anesthesie
het rectosigmoid verwijderd. Bij 12 varkens werd een circulair gestapelde end-to-end
anastomose gecreeerd (SG). Onder water werd middels een probe en een continu flow
systeem lucht ingeblazen. De maximale druk bij het ontstaan van luchtbellen ter plaatse van
de anastomose werd als ABP genoteerd. Hierna werden bij hetzelfde specimen steunhechtingen geplaatst en hetzelfde protocol werd herhaald. Ter controle is bij 10 specimen een
handgelegde enkelrijige anastomose gemaakt (HG). Deze werden volgens hetzelfde protocol
getest en ook overhecht.
RESULTATEN: Na overhechten nam in beide groepen de ABP significant toe (p<0.001 in beide
groepen).
CONCLUSIE: Het plaatsen van steunhechtingen rondom de anastomose zorgt voor een
significante toename in ABP en zou dus kunnen bijdragen aan een reductie van de
naadlekkage incidentie. Een in vivo experiment zou meer inzicht kunnen bieden in de
biomechanische en biologische effecten van de hechtingen op de anastomose.

INTRODUCTIE: Paraneoplastische neurologische syndromen hebben een gevarieerde
presentatie en worden geassocieerd met verschillende goed beschreven ziektebeelden en
daarbij beschreven antistoffen.
CASUS: Wij presenteren een casus van een 70-jarige vrouw met een subacute paraparese
van de benen. Deze werd veroorzaakt door een myelopathie secundair aan een coloncarcinoom met in het serum aanwezige anti-amphiphysine antistoffen. Patiënte verbeterde
significant na het verwijderen van de tumor en toediening van corticosteroïden.
BESCHOUWING: Bekende paraneoplastische syndromen geassocieerd met anti-amphiphysine antistoffen zijn stiff-person syndroom, encephalomyelitis en sensore neuropathie.
Anti-amphiphysine antistoffen worden vaak aangetoond in relatie tot niet kleincellig
longcarcinoom en mammacarcinoom.
CONCLUSIE: Anti amphiphysine antistoffen zijn eerder in de literatuur niet in relatie
gebracht met coloncarcinoom.
Case-report: A baclofen-overdosed patient with normal renal function;
treatment by hemodialysis.
S.L.M. Bontemps (SEH-geneeskunde), M. Burger (interne geneeskunde), C. Geerlings
(apotheker), P. de Feiter (intensive care)
INTRODUCTION: Baclofen is a β-(ρ-chlorophenyl) derivative of the neurotransmitter
γ-aminobutyric acid [1]. Our patient used baclofen in order to cope with her craving for
alcohol. Specifically, baclofen has shown to reduce alcohol withdrawal symptoms, as well as
to reduce alcohol craving and intake, and to promote alcohol abstinence [2]. Because
baclofen is eliminated predominantly by the kidney, baclofen-related encephalopathy is
usually found in patients with end-stage renal diseases or acute renal failure [3,4].
Therefore, hemodialysis has been suggested for those patients to alleviate symptoms and
shorten recovery time. Recently, a case was reported to reveal that hemodialysis is
beneficial to the baclofen-overdosed patient with normal renal function [5]. Here we
present a case of baclofen intoxication with normal renal function with much higher serum
concentrations of baclofen.
CASE: A 42 year old woman with a history of nicotineabuse, multiple suicide attempts and
alcoholabuse, presented at the emergency room after ingesting 120 tablets (25 mg) of
baclofen together with 10 cans of beer (500 ml). She did not receive gastric lavage and
activated charcoal administration. The patient was intubated because of deep coma
(Glasgow Coma Scale score: 3) and respiratory depression.
Her blood pressure was 119/57 mm Hg; heart rate: 62 beats per minute and body temperature: 35.8°C. Neurologic examination at admission revealed no localizing signs. Whitin an
hour we observed myoclonus and seizures. The EKG was normal at first; later she developed
a bradycardia.
The laboratory data showed normal liver function. The lactate levels were within normal
limits. The alchol-promillage was 65 mmol/l. The patient received emergent hemodialysis.
After one session of hemodialysis, the serum baclofen concentration was still high and a
second session was needed. Some side effects as hypotension, bradycardias and convulsions were present in our patient. Her consciousness returned after the completion of the
second hemodialysis treatment.
Blood samples for serum baclofen measurement were collected immediately after arrival
and at 5 (end of first hemodialysis), 6 (end of second hemodialysis), 12 and 36 hours. The
therapeutic range of baclofen is 80-400 ng/ml in normal subjects [6]. Serum baclofen
concentration at arrival was 13.3 mg/L (13.300 ng/ml).
The serum concentration of baclofen was decreased by 19.5% after the first hemodialyse
and 70.7% after the second. Symptoms like convulsions, myoclonus and bradycardias were
gone after the dialysis sessions. The patient was extubated not until day 4 and was
discharged soon after.
CONCLUSION: In conclusion: patients with baclofen overdose could show a prolonged
elimination time even with normal renal function. Thus: hemodialysis would be beneficial to
those
patients with normal renal function.

artritis (RA) hun weerslag hebben op het cardiovasculaire risico. Recente studies laten niet
alleen zien dat RA een verhoogd cardiovasculair risico met zich meebrengt maar ook dat dit
gelijk is aan het verhoogde risico bij diabetes mellitus. Recent onderzoek is vooral gericht op
het in kaart brengen van het cardiovasculair risico en de invloed van de verschillende
DMARDS (disease modifying anti-rheumatic drugs) hierop. De aandacht verschuift
inmiddels ook naar de rol van klassieke cardiovasculaire risicofactoren zoals hypertensie,
diabetes mellitus (DM) en dyslipidemie bij RA patiënten De nieuwe richtlijn cardiovasculair
management meldt ook dat patiënten met RA, net als patiënten met DM, gezien moeten
worden als een hoogrisico groep. Ook de laatste richtlijn van de EULAR (European League
Against Rheumatism) wijst op een hoog risico en de noodzaak om als reumatoloog een
actieve houding aan te nemen t.o.v. cardiovasculaire risicofactoren. De FRANCIS studie is de
eerste interventiestudie die naar behandeling van deze klassieke cardiovasculaire risicofactoren bij een RA-patientengroep gaat kijken. De studie is een nauw samenwerkingsverband
tussen de afdelingen reumatologie, interne geneeskunde en klinische chemie van het Sint
Franciscus Gasthuis.
VRAAGSTELLING: Is een strikt interventieprogramma (tight control) voor cardiovasculaire
risicofactoren effectief in het verminderen van intima media dikte (subklinische atherosclerose) t.o.v. het huidige standaard beleid (usual care) bij patiënten met reumatoïde artritis?
METHODE: Een gerandomiseerde open label klinische trial met parallel daaraan een
prospectief cohort. Patiënten met RA van 70 jaar of jonger en zonder cardiovasculair event
en/of diabetes mellitus in de voorgeschiedenis die tussen 1 januari 2011 en 27 januari 2012
de polikliniek reumatologie bezochten werden geincludeerd (inclusie loopt nog). Geincludeerde patiënten met een cardiovasculair risico volgens de score tabel >10% ontvangen
tight control en worden prospectief gevolgd. Geincludeerde patiënten met een cardiovasculair risico volgens de score tabel <10% worden 1:1 gerandomiseerd voor tight control of
usual care. Tight control is een geprotocolleerde behandeling ,met strikte streefwaarden
voor bloeddruk, cholesterol, glucose en een actieve houding t.o.v. overgewicht en roken, op
het diabetes en vasculaire centrum. Usual care betekent terugverwijzing naar de huisarts
voor behandeling, waarbij patiënten wel 2 keer per jaar gecontroleerd worden in het
diabetes en vasculair centrum. Van alle patiënten worden klinische en biometrische
gegevens, laboratoriumwaarden, RA ziekteactiviteitsscores en intima media diktes
gecontroleerd gedurende 5 jaar. In totaal zullen 316 patiënten gerandomiseerd worden.
RESULTATEN: Momenteel zijn 242 patiënten gerandomiseerd en 7 patiënten geïncludeerd in
het hoog risico cohort. In april zullen de eerste resultaten gepresenteerd worden.
CONCLUSIE: Patiënten met RA hebben een hoger cardiovasculair risico dan patiënten zonder
RA. De FRANCIS studie is de eerste interventiestudie die kijkt naar verschil in progressie van
subklinische atherosclerose bij verschillende behandelstrategieën.

INTRODUCTION: In most patients euthyroidism, thyrotoxicosis or hypothyroidism is
confirmed with the combination of free T4 (FT4) and thyroxin stimulating hormone (TSH)
measurements. Discrepancies between thyroid function tests and the patient’s clinical
status should question immunoassay validity. Merely relying on the thyroid function tests
may lead to inappropriate treatment. In this study we evaluate several interfering antibodies
on four different thyroid hormone immunoassays and the gold standard equilibrium dialysis
in order to investigate possible methods to overcome these.
MATERIAL AND METHODS: We performed FT4 measurements on four different analyzers
(Cobas Modular; Roche, Immulite 2500; Siemens, DXi; Beckman Coulter, Vitros Eci; Ortho
Clinical Diagnostics) and compared these to the gold standard equilibrium dialysis. Two
patients with aberrant free T4 (FT4) results, two patients with human anti-mouse antibodies (HAMA) and rheumatoid factor (RF), respectively and two external quality samples were
included in this study. All samples were measured before and after treatment with
heterophilic blocking tubes (Scantibodies Laboratory) or protein A/G agarose beads
(Thermo Scientific).
RESULTS: Surprisingly the HAMA (2464 ng/ml) and RF (440 IU/ml) positive samples showed
no interference on four different FT4 immunoassays and the dialysis method. Aberrant FT4
patient results were only encountered in the Immulite immunoassay whereby the results
were falsely elevated. This interference was eliminated after treatment with protein A/G
agarose beads but not after heterophilic blocking tube treatment. Furthermore, no thyroid
hormone auto-antibodies (THAA) were detected using gel electrophoresis. Remarkably both
samples were positive for anti-thyreoglobuline (anti-TG). Heterophilic blocking tube and
protein A/G treatment had no significant effect on FT4 results in the external quality
samples.
CONCLUSION: Anti-TG is a possible cause of interference in the Immulite immunoassay
giving falsely elevated results. Treatment with protein A/G, but not heterophilic blocking
tube treatment, removed the antibody interference. HAMA, RF and anti-TG exhibit no
interference on the Modular, DXi, Vitros analysers or the dialysis method. Furthermore,
treatment with protein A/G or heterophilic blocking tube gave reproducible FT4 results.

INTRODUCTION: Leukocyte differential counting is a frequently performed diagnostic test.
When the automated leukocyte differential generated by a hematology analyser does not
meet specific criteria, a microscopic differential is performed. Disadvantages of microscopy
are the limited number of counted cells and significant statistical and inter-observer
variation. Several laboratories published flow cytometric protocols to perform single-tube
leukocyte differentials. Advantages over microscopy are the increased number of counted
cells (several ten-thousands) and objective immunological definitions of an increased
number of leukocyte populations. Comparison of different flow cytometric protocols on a
single data set has not been reported yet.
GOAL: The aim of this study was to compare 2 different flow cytometric leukocyte differentiations: Leukoflow (developed by us) and CytodiffTM (Beckman Coulter) with the results from
the hematology analyzer and microscopy.

WETENSCHAPSDAG SFG 2012
METHOD: For 217 EDTA blood samples we compared leukocyte differentiation by a
hematology analyzer (LH750; Beckman Coulter) and flow cytometry using both Leukoflow
(10 antibodies) and Cytodiff™ (6 antibodies) protocols on a 5-color flow cytometer (FC500,
Beckman Coulter). For 110 samples a 2x200 cell microscopic count was performed by 2
technicians.
RESULTS: When comparing the results from both flow cytometric protocols with the
hematology analyser and microscopy we see good correlations between the four techniques
for the neutrophils (0.85-0.98), lymphocytes (0.90-0.98) and eosinophils (0.96-0.99). For
monocytes the correlations are slightly lower (0.81-0.98). The correlations for basophils
range from very poor (r=0.11, hematology analyser versus Leukoflow) to good (r=0.90,
microscopy versus CytodiffTM). For immature granulocytes (counted by microscopy), the
correlation with CytodiffTM and Leukoflow is 0.66 and 0.73 respectively. Microscopical blast
counts correlate well with CytodiffTM and Leukoflow results (r=0.99 and 0.86 respectively).
Plasma cell counts by microscopy correlated well with Leukoflow results (r=0.98). The
automated gating software provided with the CytodiffTM protocol gave correct gating
results for ~75% of the samples.
CONCLUSION: Leukocyte differentiation by flow cytometry can be an alternative to screen
samples flagged for microscopical review. In the Leukoflow protocol all non-classified cells
are counted as basophils, resulting in poor correlations for the Leukoflow basophils counts.
In routine practice this can be circumvented by comparing the basophil count by Leukoflow
with that of the hematology analyzer. Discrepancies should be investigated because
aberrant cell populations are present. This was corroborated by several abnormal samples
in our dataset. Advantages of Leukoflow are its ability to identify plasma cells and to obtain
a CD34-based blast count. For use in a routine diagnostic setting, automatic gating
software, as provided with CytodiffTM, is an advantage, however an additional system to flag
aberrant results is required.

INLEIDING: Bij chronisch obstructieve longziekten (COPD) komen frequent benauwdheidsaanvallen (exacerbaties) voor, waarvan ongeveer 30% met een bacteriële oorzaak. De
overige 70% wordt veroorzaakt door een virale infectie of andere oorzaak. Voor het correct
starten met antibiotica is het belangrijk bacteriële en niet-bacteriële exacerbaties goed te
onderscheiden. Hiervoor worden het sputum-aspect, absolute leukocytengetal, CRP en
thoraxfoto’s gebruikt. Ongeveer 60% van de exacerbaties krijgt antibiotica. Er is dus sprake
van overbehandeling, met als risico resistentieontwikkeling.
VRAAGSTELLING: Wij testen of bacteriële en niet-bacteriële COPD exacerbaties beter
onderscheiden kunnen worden met extra diagnostische bloedtesten, deels gebaseerd op
flow cytometrie. Hierdoor zou het onnodig gebruik van antibiotica voorkomen kunnen
worden.

bepalingen gedaan: automatische leukocyten differentiatie (hematologie analyzer),
immunologische flow cytometrische leukocyten differentiatie (Leukoflow en CytodiffTM),
flow cytometrische Leuko64 sepsis detectie kit (IQP/Trillium Diagnostics) en procalcitonine
(Thermo Fisher/Brahms). Inclusie criteria: COPD GOLD klasse 1-4, geen recent antibiotica of
prednison gebruik, geen systemische ziekte of maligniteit. Op basis van klinisch beloop en
de uitkomst van de sputumkweek is de patiëntengroep retrospectief ingedeeld in bacteriële
en niet-bacteriële exacerbaties. Met ROC-curves is gekeken welke test deze groepen het
beste kan onderscheiden op basis van de “area under the curve” (AUC).
RESULTATEN: De inclusie van patiënten loopt nog. Tot nu toe zijn patiënten met bacteriële
(n=7), en met niet-bacteriële COPD exacerbaties (n=10) en COPD patiënten zonder
exacerbatie (n=18) geïncludeerd. Tussentijdse analyse wijst uit dat de parameters die de
bacteriële exacerbaties het beste kunnen onderscheiden zijn:
1) eosinofiele granulocyten (hematologie analyzer en flow cytometrie), AUC: 0.792,
sensitiviteit 83%, specificiteit 75%.
2) CD4-positieve T-cellen (flow cytometrie: Leukoflow), AUC: 0.778, sensitiviteit 86%,
specificiteit 57%. Het onderscheidend vermogen van deze parameters is vergelijkbaar met
CRP (AUC 0.778, sensitiviteit 71%, specificiteit 78%) en groter dan het absolute leukocyten
getal (AUC 0.543, sensitiviteit 86%, specificiteit 30%), procalcitonine (AUC 0.543, sensitiviteit 57%, specificiteit 50%), en de Leuko64 sepsis detectie kit (AUC 0.733, sensitiviteit 83%,
specificiteit 40%).
CONCLUSIE: Voor het onderscheiden van bacteriële versus niet-bacteriële exacerbaties
COPD is de absolute leukocyten concentratie slecht bruikbaar. Veelbelovend zijn de
CD4-positieve T-cellen, bepaald met Leukoflow. Het absolute aantal eosinofielen lijkt een
goed onderscheidende parameter, die eenvoudig bepaald kan worden met bestaande
technieken (hematologie analyzer).

noodzakelijk is, uitgenodigd om deel te nemen aan het voorlichtingsproject. Patiënten en
hun sociale netwerk worden door de medisch maatschappelijk werker voorgelicht over
vormen van nierfunctievervangende therapie, levende donatie en de impact die dit heeft op
de kwaliteit van leven van de patiënt. De voorlichting vindt plaats in de thuissituatie van de
patiënt. Om het effect van de voorlichting op kennis en communicatie te toetsen, wordt er
voor- en na de bijeenkomsten een enquête afgenomen. Kennis wordt gemeten op een
schaal van 0-30.
UITKOMSTEN: Van oktober 2011 t/m februari 2012 zijn 19 patiënten benaderd, waarvan 14
patiënten hebben deelgenomen aan de voorlichting. Het kennisniveau van de patiënten die
de nefroloog hebben bezocht in het SFG ligt gemiddeld op 17.4 (SD=3.6).
Dit geeft aan dat er behoefte is aan informatie in een eerder stadium. De voorlichting wordt
door de patiënten als positief ervaren (Gemiddeld 1,25 ± 0,45 range 0-7). Zij zijn tevreden
over de inhoud van de voorlichting en de bijdrage van de medisch maatschappelijk werker
(Gemiddeld 1,25 ± 0,45 range 0-7). Ze vinden de voorlichting duidelijk (Gemiddeld 1,17 ±
0,39 range 0-7). Gemiddeld zijn er 5 genodigden bij de voorlichting aanwezig (range 2-11).
De medisch maatschappelijk werker evalueert de bijeenkomsten als positief. Er werden veel
vragen gesteld en er was veel interactie. Als nadeel werd ervaren dat de voorlichting minder
gestructureerd werd als er veel mensen aanwezig waren.

INTRODUCTION: Binding of apolipoprotein (apo) B containing lipoproteins to erythrocytes
may be an atheroprotective mechanism. The binding mechanism remains speculative since
erythrocytes do not have LDL-receptors. However, erythrocytes are known for their immune
adherence and transport of C3b-opsonised ligands by the complement receptor type 1
(CR1). We investigated erythrocyte-bound apoB (ery-apoB) in relation to carotid intima
media thickness (IMT) in a large population and carried out experiments to investigate the
role of CR1 in binding apoB-containing lipoproteins using an in vitro model.
METHODS: Ery-apoB was measured by flowcytometry using polyclonal anti-apoB antibodies.
A carotid IMT of more than 0.70 mm was considered increased, reflecting (subclinical)
atherosclerosis. Transfected Chinese hamster ovarian (CHO) cells, which expressed CR1
(CHO-CR1), and control CHO cells (CHO-R) were used for in vitro experiments to investigate
isolated LDL binding to CR1.
RESULTS: Subjects with increased carotid IMT (>0.70 mm) (N=145) had a lower ery-apoB
(0.89 ± 0.83 a.u.) compared to those with normal IMT (N=254) (1.16 ± 0.92; N=254,
P=0.007). Ery-apoB was inversely correlated with IMT (Spearman r: -0.116, P=0.021).
CHO-CR1 significantly bound more apoB containing lipoproteins from serum compared to
CHO-R (8.1±2.0 a.u. versus 5.2±1.1 a.u., P<0.001). Binding of isolated LDL was significantly
higher to CHO-CR1 compared to CHO-R, but only when LDL was opsonised. Native LDL

bound similarly to both cell types, suggesting the presence of an alternative binding site,
most likely the LDL receptor. Binding of LDL to CR1 could be diminished in a dose response
by using heat inactivated serum, which disrupts the function of the complement system,
instead of normal human serum.
CONCLUSION: This study provides further proof of a protective effect of apoB containing
lipoproteins bound to erythrocytes on atherosclerosis. The presence of apoB on erythrocytes can be explained by the capacity of CR1 to bind LDL after opsonisation by complement
factors. Immune adherence of apoB-containing lipoproteins to erythrocytes may be
operational in vivo.
Case report: a spinal epidural abscess.
BACKGROUND: A spinal epidural abscess (SEA) is an uncommon condition with an incidence
of 0.2 to 2 per 10.0000 hospital admissions per year. Classical symptoms of SEA are spinal
pain, fever and neurological deficit. In most cases this triad is not present. Most common
complaints are not specific; these include back pain, neck pain and radicular pain. Fever is
not always present. For this reason, the diagnosis SEA can be easily overlooked. If not
treated early in development, a SEA is a life threatening condition. Therapy of choice is early
neurosurgical intervention together with long term antibiotics. In the majority of cases
infection is caused by S. Aureus. Choice of antibiotic treatment should be adjusted
accordingly.
CASE DESCRIPTION: We present a 56-year-old woman who visited the emergency department because she had progressive back pain, radiating into the left leg which started six
days before presentation. She also had loss of motor function of the upper leg. Fever was
not present, nor were there any other signs of internal or neurologic deficit. Laboratory
findings showed highly elevated C-reactive protein (>500 mg/l) and leukocytosis (>20 x
109/l). Imaging studies showed multiple abscesses. There was a spinal epidural abscess
ranging from L2-L4, an abscess in the left psoas muscle and in the paravertebral muscles.
There was also severe infiltration in both lungs. Puncture of the paravertebral muscle
abscess showed infection with Staphylococcus Aureus. The patient was treated with
parental flucloxacillin and oral rifampicin together with CT-guided needle aspiration of the
psoas muscle abscess.
The patient responded very well to this therapy and after two weeks the parenteral
antibiotics were replaced by oral clindamycin. The total duration of treatment was seven
weeks.
CONCLUSION: A spinal epidural abscess is a potentially life threatening condition. Mortality
rates are still substantial, because there is a delay in early recognition. Outcome depends
mainly on the patient’s neurological status and the duration of symptoms. Therapy of choice
is neurosurgical. We presented a patient who was successfully treated with CT guided
needle aspiration combined with antimicrobial therapy, without neurosurgical intervention.

ceerde zwangerschap. Twee dagen voor de partus voelde zij minder leven en een dag voor de
partus werd zij door een gynaecoloog gezien. Vanwege een weinig acceleratief CTG werd zij
doorgeleid en beviel zij een dag later van een zoon. Er was sprake van een snelle bevalling en
een matige start waarbij hij kortdurend is bijgeblazen met 100% FiO2. Er werd bloed
afgenomen en er bleek sprake te zijn van een anemie (Hb 4.2, Ht 0.22). Hij kreeg hiervoor
een erytrocytentransfusie. Vanwege een matige circulatie werd hij gevuld met NaCl 0.9%.
Daarnaast krijg hij een bolus glucose bij een eerste glucose van 1.1 mmol/l. Er werden bij
moeder o.a. TORCHES en parvo B19 ingezet, een Kleihauer test gedaan en antistoffen
bepaald. Post transfusie steeg het Hb van het kind tot 7.5 mmol/l. Het LDH is op dag 1
(na 24 u) 5370 U/l en is 3 dagen na de geboorte nog 2483 u/l. Bilirubine steeg tot maximaal
228 µmol/l op dag 4. Het percentage reticulocyten was na 24u 5,7 % en na 48u 15,6 %.
Op dag 6 is het jongetje ontslagen met een Hb van 6,9. Het Hb op dag 10 is 6,6 mmol/l.
RESULTATEN: De Kleihauertest was positief (2% foetale cellen, wat overeenkomt met 100 ml
foetaal bloed bij de moeder). Bij de moeder werden irregulaire antistoffen aangetoond anti
Jk(a). De directe antiglobuline test bij kind en moeder waren negatief (Diamed). Omdat de
DAT van moeder en kind negatief waren (Diamed), maar zwak positief met Immucor, werd
van beiden een eluaat ingezet. In het eluaat zowel van moeder als van kind, werden Jk(a)
antistoffen geëlueerd. De herhaling van de screening van de 12e week was negatief.
De moeder was homozygoot Jk(b) positief , de vader was homozygoot Jk(a) positief. Het
kind was heterozygoot Jk(a) Jk(b).
CONCLUSIE: De Kleihauertest toont een sterk verhoogd aantal foetale erytrocyten van het
kind bij de moeder aan. Het lage Hb en het hoog aantal reticulocyten bij de geboorte passen
ook bij een langer bestaande foetomaternale transfusie. De foetomaternale transfusie heeft
bij moeder een versnelde productie van anti Jk(a) antistoffen geïnduceerd, waardoor
erytrocyten van het kind werden gehemolyseerd.

Trefwoorden: Staphyloccocal scalded skin syndroom, Impetigo bullosa, exfoliatief toxine.

INLEIDING: Staphylococcal scalded skin syndrome (SSSS) is een gegeneraliseerde ernstige
huidinfectie. Het wordt veroorzaakt door een Staphylococcus Aureus stam die exfoliatieve
toxines (ET) produceert (incidentie 5%). Ongeveer 30% van de neonaten is binnen een week
na geboorte gekoloniseerd met S.Aureus en in ziekenhuizen verloopt kolonisatie meest
waarschijnlijk via de verpleegkundige. Het begint vaak met symptomen als koorts, lethargie,
prikkelbaarheid en voedingsproblemen. Daarna ontwikkelt zich een erythemateus huidbeeld
meestal beginnend in het gelaat en de nek welke zich in enkele dagen over de rest van het
lichaam uit kan breiden. Er worden dunne blaren gevormd die snel kapot gaan waardoor de
epidermis van de onderhuid kan loslaten (positief Nikolsky sign). Vanwege het gegeneraliseerde huiddefect is er een verhoogd risico op dehydratie, een verhoogde vochtbehoefte,
temperatuurschommelingen en bestaat er een risico op secundaire infectie.
CASUS: Een meisje geboren bij een amenorrhoeduur van 31 3/7 week, eerste van een
dichoriale-diamniotische gemelli graviditeit, lag op de afdeling neonatologie. Zij kreeg respiratoire ondersteuning door middel van CPAP. Op dag 23 werd voor het eerst een huidbeschadiging op de wang geconstateerd, nadat de CPAP was gestaakt. In eerste instantie werd
gedacht aan huidbeschadiging door de CPAP kap die met pleisters op de wang was vast
geplakt. Echter binnen een dag breidde de huidafwijking zich uit over het lichaam.

Bij lichamelijk onderzoek werd een pijnlijke, echter niet zieke neonaat gezien. De huid was
grotendeels erythemateus, vertoonde uitgebreide nattende leasies met een gelige rand en
in het gelaat daarbij enkele gele crustae. Er was sprake van een positief Nikolsky sign.
Er werd gedacht aan een secundaire huidinfectie via de open plekken op de wangen of aan
een SSSS. Er werd materiaal afgenomen voor kweken en gestart met Floxapen iv. Om de
wonden te behandelen werd in eerste instantie Fucidine zalf en zinkolie gebruikt en later
Omiderm®. In de kweken werd een S. Aureus geisoleerd welke exofoliatief toxine A en B
produceerde. De diagnose SSSS werd bevestigd. Zij werd twee weken behandeld met
antibiotica, kreeg extra vocht toediening en pijnbestrijding. Na start van de behandeling
knapte het huidbeeld snel op.
Twee dagen nadat bij dit meisje huidafwijkingen waren geconstateerd kreeg de moeder
zelfde soort huidafwijkingen op haar armen en vervolgens een dag later werd bij haar
tweelingbroer huidafwijking op zijn rechterwang gezien. Zij werden eveneens behandeld met
antibiotica nadat kweken waren afgenomen. De kweken lieten tevens een S.Aureus zien die
exofoliatief toxine A en B produceerde.
CONCLUSIE: De prognose van SSSS is goed indien tijdig wordt behandeld met antibiotica.
Daarbij een goede ondersteuning van de vitale functies en voorkomen van secundaire
infecties is van belang. Snelle herkenning is essentieel. Tevens altijd de ouders en siblings
vervolgen in verband met mogelijk dragerschap of kolonisatie.
Longfunctie is gerelateerd aan complicaties van bariatrische chirurgie.
ACHTERGROND: Morbide obese patiënten hebben een grotere kans op complicaties, met
name bij buikchirurgie.
DOELSTELLING: De relatie tussen longfunctie en complicaties van bariatrische chirurgie
onderzoeken.
METHODEN: Een retrospectieve studie van patiënten die bariatrische chirurgie ondergingen,
waarbij complicaties tot 30 dagen na de operatie werden gescoord. Spirometrie werd
pre-operatief verricht. Patiënten met en zonder complicaties werden met elkaar vergeleken.
RESULTATEN: 485 patiënten werden geïncludeerd (304 gastric sleeve resecties, 181 gastric
bypass operaties). Er vonden 52 complicaties (8 pulmonaal, 26 chirurgisch, 14 infectieus, 4
overig) plaats bij 50 patiënten (=10%). Er waren 35 heropnames (=7.2%), en 17 relaparoscopieen (=3.5%). Er was geen verschil in demografische parameters tussen patiënten met
en zonder complicaties, in het bijzonder in gewicht, BMI, buikomtrek of vetpercentage, of in
type ingreep (sleeve resectie/ gastric bypass). Patiënten met complicaties hadden een
significant lagere FEV1 (gemiddeld 86.9 % voorspeld ± 13.5) en FVC (95.6 % voorspeld ±
13.0) dan patiënten zonder complicaties (respectievelijk 95.9 % voorspeld ± 14.3, p=0.005;
100.1 % voorspeld ± 14.9, p=0.045). Patiënten met complicaties hadden significant vaker

ACHTERGROND: Astma in obese patiënten wordt slecht begrepen, en het effect van
gewichtsverlies op astma controle is niet goed beschreven.
DOEL: De effecten van bariatrische chirurgie op astma controle, kwaliteit van leven en
longfunctie onderzoeken.
METHODEN: Een prospectieve studie van patiënten met bewezen diagnose astma
(FEV1≥12% en/of PD20<1.76mg) en patiënten zonder astma die bariatrische chirurgie
ondergingen (BMI >35kg/m2, leeftijd 18-50 jaar). Longfunctie, medicatie gebruik en
kwaliteit van leven werden bekeken op baseline en 3 maanden na bariatrische chirurgie.
Obese astma patiënten die geen bariatrische chirurgie ondergingen vormden een additionele controle groep.
RESULTATEN: 35 patiënten met astma (O+A) en 50 patiënten zonder astma (O-A) ondergingen bariatrische chirurgie, 17 astma patiënten vormden de controle groep (NO+A). Er waren
geen verschillen in astma controle vragenlijst (ACQ), astma kwaliteit van leven vragenlijst
(AQLQ), FEV1 of FeNO tussen O+A en NO+A op baseline. BMI van NO+A (40 kg/m2) was
significant lager vergeleken met O+A (47 kg/m2) en O-A (45 kg/m2) (p=0.005). Na
bariatrische chirurgie daalde de BMI naar 38 kg/m2 in de O+A groep (p<0.001) en 36 kg/m2
in de O-A groep (p<0.001), waar de BMI stabiel bleef in de NO+A groep. Na bariatrische
chirurgie daalde het percentage patiënten met bronchiale hyperreactiviteit (PD20<1.76mg)
significant van 80% naar 34% in de O+A groep (p=0.003). Daarnaast daalde ook het gebruik
van inhalatie corticosteroïden met 50%. FEV1 verbeterde alleen in de O+A groep (gemiddelde 85.6 naar 94.6 %voorspeld, p=0.011). Na bariatrische chirurgie verbeterde zowel de
ACQ als AQLQ significant in de O+A groep (1.1 naar 0.5, p=0.022, respectievelijk 5.7 naar 6.3,
p=0.004), terwijl er geen verschil zichtbaar was na 3 maanden in de NO+A groep. ACQ en
AQLQ waren significant beter in de O+A groep vergeleken met NO+A na 3 maanden (ACQ
p=0.027, AQLQ p=0.002). Er was geen verbetering in FeNO in een groep.
CONCLUSIE: Bariatrische chirurgie verbetert longfunctie, astma controle en kwaliteit van
leven in patiënten met astma en morbide obesitas al na 3 maanden. Wellicht dus dat
gewichtsverlies een belangrijk onderdeel is van de behandeling van obese astma patiënten.

Intensive care
Hemodialysis is a widespread form of therapy and it is used by patients with renal insufficiency caused by various conditions (e.g. nephrosclerosis, glomerulonephritis, and
intoxications). Hemolysis during hemodialysis and its source must be quickly identified in
order to avoid or treat life-threatening complications. Only a few cases have reported this
relatively rare event. One critically ill patient is described to illustrate the effect of acute
hemolysis during hemodialysis. Our patient was admitted to the intensive care unit due to
an astma cardiale and received hemodialysis as part of the treatment course. However
during hemodialysis the patient acutely developed a severe hemolysis.

After pregnancy was obtained in a patient with microprolactinoma, bromocriptine therapy
was ceased. At 10 weeks’ gestation the patient presented with visual complaints and a
prolactin concentration of 5660 µmol/l. Visual field examination and MRI suggested
compression of the optic chiasm caused by a macroprolactinoma with pituitary tumor
apoplexy. Management with bromocriptine, levothyroxine and hydrocortisone resulted in a
decline in tumour size and a further uneventful pregnancy. This report indicates that even in
pregnant patients with a major pituitary apoplexy and visual field defects, conservative
medical treatment should be considered as the first choice of treatment
Beriberi na bariatrische chirugie
INLEIDING: Bariatrische chirugie is de enige effectieve oplossing voor morbide obesitas,
helaas zijn deze operaties niet zonder complicaties. Patienten hebben een sterk verhoogd
risico op vitaminetekorten welke vaak neurologische symptomen veroorzaken.
Beschouwing: Bij een aanzienlijk deel van de patiënten wordt na gastric bypass en gastric
sleeve operaties één of meerdere vitaminetekorten gevonden. [2,3] Risicofactoren voor
deficiënties zijn langdurige ziekenhuis opname en postoperatief braken. De meest
voorkomende deficiënties zijn ijzer, vitamine B12, vitamine D en calcium. Er wordt een breed
spectrum aan neurologische verschijnselen gezien na bariatrische chirurgie. De presentatie
varieert van binnen enkele weken na operatie encephalopathie en neuropathie terwijl jaren
na de operatie myelopathie voorkomt. [4]
Een tekort aan vitamine B1 kan leiden tot Wernicke encephalopathie, Korsakov syndroom en
Beriberi. Wernicke encephalopathie wordt gekenmerkt door de trias van oogbolmotoriekstoornissen, ataxie en verwardheid en is een medisch noodgeval. Droge beriberi, zoals
gezien bij de patiënt uit de casus, kenmerkt zich door onder andere een acute, vaak pijnlijke,
polyneuropathie. Vitamine B1 depletie kan al na 18 dagen zonder inname ontstaan. Indien
een patiënt veel braakt, zoals bij onze casus, is het dus van belang snel over te gaan op

intramusculaire toediening van vitamine B1.
BEHANDELING: Vanwege de hoge incidentie van tekorten wordt standaard laboratoriumonderzoek geadviseerd. Preventie speelt een belangrijke rol waarbij een multidisciplinaire
aanpak voor deze patiënten zeer belangrijk is. Wanneer een patiënt na bariatrische chirurgie
zich presenteert met neurologische verschijnselen danwel andere gevolgen van vitamine
deficiënties is het belangrijk om adequaat te suppleren, oraal, intramusculair of intraveneus.
CONCLUSIE: Patiënten met in de voorgeschiedenis een bariatrische operatie hebben een
ernstig verhoogd risico op deficiënties van vitamine (alle vitamines B, C, A, D, en K),
mineralen (calcium) en spoorelementen (ijzer, selenium, zink en koper). Het is van belang
om vitamine suppletie tijdig te starten om ernstige complicaties te voorkomen.
In de volgende casus presenteren wij een patient met een vitamine B1 deficientie na
bariatrische chirurgie.
Patiënt beschrijving: Een 49 jarige man met in met in de voorgeschiedenis morbide obesitas
(gewicht 129 kg, BMI 42 kg/m2) waarvoor gastric sleeve resectie 4 maanden voor presentatie, bezocht de spoedeisende hulp met aanhoudend braken, dubbelzien en verminderde
kracht aan armen en benen.
Bij neurologisch onderzoek was er sprake van desoriëntatie, een gestoorde oogbolmotoriek
en een verminderde kracht voornamelijk van de bovenbenen. Er werd een sterk verlaagde
vitamine B1 spiegel gevonden en op het EMG werd een polyneuropathie gezien. Er werd
gestart met vitamine B1 suppletie. Hierop verbeterde de patient maar matig, ondanks een
goede vitamine B 1 spiegel. Hij confabuleert, heeft geheugenproblemen (passend bij het
syndroom van Korsakov) en de kracht verbetert langzaam, hij verblijft in het revalidatie

Uterine artery pseudoaneurysm is a rare but well described cause of massive and often
delayed postpartum hemorrhage. Uterine artery pseudoaneurysm during pregnancy is
extremely rare. In this case a pregnant woman presented with vaginal blood loss at a
gestational age of 27 weeks. Transvaginal ultrasound disclosed a para-cervical mass with a
diameter of 3 x 4 x 4 centimetres, suspicious for endometriosis. Using colour Doppler a
classic Yin-Yang sign typical for a pseudoaneurysm was observed. Embolisation of the
aneurysm and the proximal uterine artery was performed successfully. However, the patient
returned with vaginal blood loss after 3 days. A second attempt for embolisation was
performed, resulting in occlusion of the aneurysm and both the proximal (afferent) and
distal (efferent) course of the uterine artery. Thereafter vaginal bleeding did not recur. At a
gestational age of 37 weeks an elective caesarean section was performed, with a good
maternal and fetal outcome. This is the first case reporting prolongation of a pregnancy
following embolisation of a uterine artery pseudoaneurysm.

INTRODUCTION: Cryoglobulinemia is defined as one or more immunoglobulins in the serum
which precipitate at temperatures below 37C and dissolve again on rewarming. Criteria for
the classification of cryoglobulinemia patients are based on serologic, pathologic and
clinical findings. We present a patient with hepatitis C negative mixed type cryoglobulinemia.
CASE REPORT: A 58-year old Caucasian man was admitted to the Intensive Care because of
an arterial occlusion and was treated with urokinase and stenting. During admission he was
successfully treated with clarythromycin because of pneumonia. One month after discharge
the patient returned with hypoxemia with massive hemoptysis. He was readmitted to the
Intensive Care for intubation and mechanical ventilation. Physical examination showed
erythematous lesions on his lower extremities, biopsy showed a leukocytoclastic vasculitis.
We found an increased level of creatinine with dysmorphic erythrocytes in the urinanalysis,
suggesting glomerulonephritis. Decreased levels of C3, C4 and an elevated C1q-bindingtest
suggested activation of the immune system. Over time the patient developed progressive
renal failure, all tests for auto-immune diseases (ANA, ENA, ANCA, anti-CCP) were negative
except for a positive IgM rheumatoid factor. Also viral tests including hepatitis C RNA were
negative. Because of a possible seronegative Wegener granulomatosis he started with
prednisone, cyclophosphamide and plasmapheresis, with poor result. Additionally a
monoclonal IgM-kappa paraprotein and cryoglobulins were present in the serum. Bone
marrow biopsy (performed after initial treatment) showed 1% plasmacells and 15%
B-lymphocytes with an increased kappa/lambda ratio of 47, the ratio of kappa/lambda free
light chains in the serum was also increased (ratio 23). We concluded that the patient had a
hepatitis C virus negative mixed cryoglobulinemia (type 2) with diffuse alveolar haemorrhage, leukocytoclastic vasculitis of the skin and glomerulonephritis. He was treated with
prednisone 1mg/kg daily and rituximab 375 mg/m2 weekly for 4 weeks. Currently he is
doing well and is treated with prednisone (tapering scheme) and rituximab every three
months (for 2 years according to non Hodgkin lymphoma protocols). Kappa/lambda ratios,
IgM, complement levels etc. are normalised and cryoglobulins can not be detected anymore.
CONCLUSION: Cryoglobulinemia mixed type 2 is an immune complex-mediated systemic
vasculitis. In a majority of cases it is induced by B-cell activation by the hepatitis C virus,
therefore HCV-negative cryoglobulinemia is very rare. It is unknown what the causative
factors are involving HCV-negative cryoglobulinemia mixed type 2, but this diagnosis should
always be considered in HCV-negative patients.

Anamnestisch bleek patiënte bij drukverhogende momenten vocht aan onderzijde te
verliezen: vaginaal of urethraal.
Aanvullend onderzoek toonde een blaasretentie van 320cc en een CT-abdomen liet een
gedeeltelijk gevulde blaas zien met een kleine verkalking passend bij een blaassteen. In
verband met deze opmerkelijke bevinding werd de uroloog in consult gevraagd. Cystoscopie
toonde een blaasempyeem op basis van een rubberen corpus alienum. Deze werd verwijderd
en na het spoelen van de blaas werd gentamicine achtergelaten.
Bij nadere bestudering bleek het te gaan om een stukje van een oude blaascatheter.
Patiënte bleek twintig jaar geleden voor de laatste keer gecatheteriseerd was.
DIAGNOSE: Blaasempyeem op basis van oud stukje blaascatheter bij een anefrische- hemodialyse patiënte.

INTRODUCTION: Bariatric surgery (BS) is a popular and effective method in the treatment of
morbid obesity. In the majority of patients BS results in significant weight loss. Symptoms
and signs of orthostatic hypotension following rapid weight loss have been described
especially in starvation, but may also occur after BS. We describe three patients with severe
orthostatic intolerance after BS.
Case report: Three patients (two males and one female; mean age 44.3 ±2.9 years) who had
undergone BS and developed clear symptoms of orthostatic intolerance and were admitted
to the hospital. On average they lost 54.0 ± 20,2 kg body weight (representing 37.4 ±9.9 %
of their original body weight). Their initial BMI was 42.2 ±3.2 kg/m2 which decreased after
laparoscopic sleeve resection to 26.1 ±2.9 kg/m2. All three subjects developed new-onset
syncope, near-syncope and dizziness within a mean term of 13.3 ±8.1 months after surgery.
Their mean systolic blood pressure decreased from 132.5 ±10.6 mmHg to 117.5 ±24.7 and
their heart rate decreased from 81.0 ± to 55.5 ±14.8 bpm. ECG, electrocardiography and
24 hrs holter registration were normal. None of the patients had deficiencies of vitamins or
minerals and there were no other biochemical abnormalities responsible for their
symptoms. Based upon these results all three patients were diagnosed with (postural)
orthostatic hypotension following excessive weight loss.
DISCUSSION: BS is an effective method to treat (morbid) obesity. Orthostatic hypotension
can be a severe side-effect of BS and has been described previously. Its exact incidence and
etiology is unknown. The likely mechanism of orthostatic failure is autonomic insufficiency
combined with reverse course of obesity-related hypertension. In general, the orthostatic
hypotension disappears if the patient regains weight. As BS is getting more popular in the
Netherlands, more people presenting with orthostatic intolerance following rapid weight
loss are expected. Further investigations will be necessary to determine the exact incidence
of orthostatic intolerance and to identify those patients at greater risk for developing
orthostatic intolerance following BS.
