Rheumatoid Arthritis
Rheumatoid arthritis (RA) is a systemic disorder of immune regulation which is
characterized primarily by articular manifestations. Joint synovial linings demonstrate
progressive proliferative changes which often ultimately progress to destruction of the
joint space and underlying cartilage with loss of function of the articular unit.
Rheumatoid nodules may also form in subcutaneous tissues overlying easily
traumatized bone (such as upper extremity extensor surfaces) and may also be found
in other tissues and organs (lung, skeletal muscle, etc.) These nodules demonstrate
central paucicellular areas of eosinophilic necrosis which are flanked by rows, or
palisades of histiocytes and other inflammatory cells. The pathogenesis underlying the
formation of these nodules is not completely understood; they are noted in
approximately 25% of patients with RA.
Rheumatoid vasculitis is a well-described entity in RA patients, and can be a
serious threat to function and life, depending upon the size and location of the
involved vessels. Blindness, peripheral neuropathies, cerebrovascular accidents, and
skin ulceration with gangrene has been noted in these patients; this complication is
most often noted in patients with the highest rheumatoid titers.
In the laboratory, a diagnosis of rheumatoid arthritis is supported (in the proper
clinical context) by the identification of so-called Rh factor, an anti-self antibody
noted in over 80% of RA patients. Most of these antibodies are of the IgM subtype,
and show specificity for the Fc portion of the IgG molecule. These antibodies form
circulating complexes with their respective IgG antibodies; these complexes form
deposits in synovial membranes and are felt to contribute to the formation of the
typical synovitis and pannus of RA through the activation of complement in situ.
Similar activity in the extraarticular tissues (renal glomerulus, small systemic vessels,
etc) cause many of the disease manifestations in these regions. In the absence of
identifiable Rh factor in serum or synovial fluid, the diagnosis of "seronegative" RA
is made on a clinical basis, with the findings of symmetrical arthritis affecting three or

more areas and especially involving joints of the hand, typical radiologic findings of
RA (narrowing of the joint spaces, marginal erosions, and digit deviations or
subluxations), morning stiffness, and the identification of rheumatoid nodules (usually
not identified in absence of elevated Rh titer). The disease course of RA is variable,
with most cases of a chronic nature with periodic exacerbations. Death, if related to
RA, is usually due to complications of vasculitis and chronic vessel changes
(including amyloid depositions in vessel walls) and therapy-related complications
(infections secondary to chronic immunosuppression, or coagulopathy secondary to
NSAID overuse).
Progressive pseudorheumatoid arthritis of childhood (PPAC) is a rare
atuosomal recessive disorder, resembling rheumatoid arthritis, especially the
seronegative spondylo-arthropathies of childhood(1). However, there is no
inflammation of the joints and it has been demonstrated that the disorder is actually
due to a non inflammatory chondropathy affecting mainly the articular cartilage(1,2).
An early clinical diagnosis is difficult and it is the characteristic radiological features
which help in an early recognition of the disease. Three cases have been reported
from India earlier(3,5). We report here a case of PPAC presenting to us at the age of
11 years, who was diagnosed for the first time at our center on the basis of clinical
and radiological features. However, this patient was different from the other reported
cases in having prominent facial dysmorphism.
Goals Of RA Treatment :
The goal of management of RA are to:
1. Relieve pain and inflammation.
2. Prevent joint destruction.
3. Preserve or improve patient’s functional ability.

2.1 Patient Counsling:
Patients with Rheumatoid Arthritis (RA) must be appropriately educated and
counselled as it is really vital point. Patient Education Only Part of a Good RA
Management Program as the patient should have a knowledge of the disease process,
the likely prognosis and the treaetment strategy.
Patient counsling should reinforce the need to comply with monitoring requirements,
the time delay before a response is seen, potential toxicity and action to take in the
events of adverse effects.
NSAID’s preparations should be taken with or after food, the patients should be
warned of potential adverse effects and what to do if these occur.
Non Drug Treatment :

Rest & Nutrition :
Complete bed rest is recommended for a short period during the most active ,painful
stage of severe diseaes. In less severe cases, the clinical pharmacist should prescribe a
regular rest.
An ordinary nutritious diet is generally sufficient. Rarely, patients have foodassociated exacerbations. Fish or plant oil supplements may partially releive the
symptoms because they can decrease production of prostaglandins.

Physiotherapy :
Physiotherapy is a vital part of treating RA in a patient, both in acute flares of disease
and in the chronic state.

Section ll
Heat, Cold & electrotherapy help to reduce pain and swelling, and a programme of
exercise strengthens joints to prevent disuse atrophy, mobilize joints to minimize
deformity and increase the range of movement and functions.
Occupational therapy educates patients to protect joints, improve function by means
of exercise and use of aids and appliances, and provide splints to rest and protect
joints.
Surgical techniques ranging from carpal tunnel decompression to major joint
replacement can be effective in relieving pain and restoring functions.
With more aggressive and effective drug treatments becoming available the frequency
of surgical intervention may reduce.

2.2 Choice of drug therapy :
The cyclooxygenase (COX)-2 inhibitors are a the better choice for such patients, since
they appear to have a lower risk of gastrointestinal toxicity. The improved safety of
these drugs should not be assumed to imply improved efficacy, however. No
nonsteroidal medication can alter the course of rheumatoid arthritis; they do not
change radiographic progression or slow joint destruction. For that reason, they
should be used as adjuncts, never as monotherapy.
NSAIDs has the following specific interactions:

ACEI’s
INTERACTION
Aspirin and other NSAID’s have been reported to reduce the
hypotensive effects of ACEI’s via inhibition of PG synthesis.
Ca channel blockers
The antiplatelete effects of aspirin and Ca channel blockers
may be increased when they are used together.
Diuretics
They decrease the hypotensive effect of the diuretics as the
combination is generally contraindicated. The mechanism of
may be interference with the production of renal PG which is
required to mediate the action of the diuretics.
All other antihypertensives
Caution should be exercised when NSAID’s are given to
patient receiving antihypertensives as their effect is reduced.

NSAID’s may inhibit latelet function and enhance
the hypoprothrombinaemic effects of warfarin. The

CASE STUDY # l :
A 52-year-old female with a 21-year history of deforming polyarticular symmetrical
inflammatory arthritis predominantly involving the wrists and metacarpophalangeal
(MCP) joints, as well as the knees and ankle joints. She was referred to the arthritis
center by her primary care physician for evaluation and treatment. For the previous 6
months, the patient has had nodules around her hand joints, elbows, and over the
Achilles tendons. An ulcer that appeared over the right malleolus following minor
trauma 3 weeks previously had not healed following application of local dressings.
The patient is married and has no children. She is a social worker and lately it has been
difficult for her to work full time, drive her car, and take care of her house. She
smoked for 20 years but has recently stopped. She has been menopausal for 5 years
and has refused estrogen replacement therapy. The patient's mother fractured her hip at
age 72 years and the patient had a sister who died of breast cancer at age 55 years.
Examination showed extensive nodules over her hands, advanced ulnar deformity with
subluxed second and third MCP joints and small effusion in her knee joints that had
not been aspirated. Her leg ulcer did not show good granulation and was secondarily
infected. There was evidence of peripheral neuropathy up to the ankles bilaterally.
Small vasculitis lesions were present on her lower extremity, some of which had
necrotic areas. Her spleen was palpable and there was evidence of epigastric
tenderness on abdominal examination.
Laboratory evaluation showed that her hemoglobin level was 10.9 g/dL with
microcytosis and she had low serum iron. Her leukocyte count was 3200/micro-L with
evidence of neutropenia and a peripheral smear showed large, granular lymphocytes.
Platelet count was 450000/micro-L, erythrocyte sedimentation rate (ESR) was 72
mm/hr and rheumatoid factor was 1:1280. Her fasting blood glucose was 72 mg/dL,
blood urea nitrogen (BUN) was 38 mg/dL and serum creatinine was 2.1 mg/dL

Section lll
The patient's current medications include ibuprofen 800 mg 4 times per day,
hydroxychloroquine 200 mg twice daily, and prednisolone 5 mg per day. She had been
continuously on prednisolone at an average dose of 7.5 mg per day for the last 7 years.
Six months ago, she was tried on methotrexate but it caused severe stomatitis and
abnormal hepatic transaminases levels.
Part 1: ( See Q & A # 1 )
This patient has several features of progressive, active rheumatoid arthritis, including
active synovitis, elevated ESR, high rheumatoid factor and evidence of rheumatoid
nodules and vasculitis rash. Despite the use of a (NSAID), prednisolone, and
hydroxychloroquine, her disease has been progressive. Moreover, there are several
adverse effects that could be related to her therapy, namely microcytic anemia and
renal dysfunction. Her history of methotrexate toxicity and the strong family history of
osteoporosis with hip fracture also represent potential problems.
Part 2: Continuation of Case ( See Q & A # 2 )
The patient returned 3 weeks later and her leg ulcer looked clean. However, she had
new vasculitic lesions on her lower extremities and she complained of polydypsia and
polyuria. Her fasting blood sugar was 162 mg/dL, although her BUN and serum
creatinine had improved with values of 32 mg/dL and 1.6 mg/dL, respectively. The
patient, therefore, has not responded well to prednisolone and she has early signs of
iatrogenic diabetes mellitus.
Part 3: Continuation of Case ( See Q & A # 3 )
The patient is at risk of developing osteoporosis because of prolonged use of
corticosteroids, being menopausal without taking anti-osteoporosis measures, leading
a sedentary lifestyle and having a family history of hip fracture.

Questions And Comments About The Case Study
Q1: What would be the most appropriate strategy for managing the
patient's leg ulcer with vasculitis and neuropathy?
The other issues needing to be discussed are the periperal neuropathy, vasculitic skin
lesions, and neutropenia with splenomegaly. This constellation of findings in the
patient with longstanding RA should lead to a diagnosis of Felty's syndrome. Also of
interest is the reference to large granular lymphocytes. This particular variant of
Felty's syndrome may actually present earlier in the course of the disease.
Certainly it would be helpful to know the actual neutrophil count, as extremely low
counts increase the risk of systemic infection, especially in the patient on
glucocorticoids. If the absolute neutrophil count were as low as 500, consideration
should be given to using a course of granulocyte colony stimulating factor. Lithium
and testosterone have also been used, but controlled studies of these agents is very
limited.
Gold injections and penicillamine have both been reported to be beneficial in the
management of Felty's syndrome, although these agents have been used less frequently
since the addition of methotrexate to the armamentarian. To date I know of no
reference to the use of ARAVA or ENBREL in this setting, but would imagine a
benefit if the drugs were tolerated. Imuran has also been used in this setting, as well as
cytoxan, but the risk of bone marrow suppression would require extremely careful
monitoring of the patient.
Using IV Imunoglobulin is benificial
.Having diabetes
and taking Prednisolone will certainly interfere with
healing. So the doctor should use becaplermin to help start granulation tissue.
Her NSAID treatment should be stopped because of her renal dysfunction and
possible occult gastrointestinal bleed. She should be started on an anti-gastritis
regimen, such as PPI’s with an iron supplement for her anemia.
Yosra Ashraf
19
Rheumatoid Arthritis
Section lll
To treat her leg ulcer, she needs to be on an antibiotic, such as cephalexin,
with local dressings applied.
The dose of oral prednisolone should be increased to 1 mg/kg daily for at least
seven to ten days and then lowered according to her progress.
Methotrexate cannot be used because of her renal dysfunction and past history
of methotrexate toxicity. She will continue her other medications, including
hydroxychloroquine.
Baseline tests for osteoporosis should be performed, including bone
densitometry measurements to determine the risk of fractures.
Measurements of thyroid function, serum calcium, serum phosphorus, 25hydroxyvitamin D and kidney function should be made.
If her bone density was found to be in the osteopenia range and the other tests
showed normal values, the patient should be started on calcium and vitamin D
at respective daily doses of 1500 mg and 400 units. The third generation
bisphosphonate alendronate would also be recommended.
An estrogen should not be given because of the patient's family history of
breast cancer. However, a "designer estrogen", such as Evista ® (raloxifene),
would be a good alternative if she is intolerant of alendronate. Like estrogen
replacement therapy, raloxifene increases bone mineral density but it is not
associated with endometrial changes or breast malignancy.

Q2: What would be the proper course of action now, given that the
patient still has progression of vasculitis as well as early signs of
iatrogenic diabetes mellitus?
A steroid-sparing, cytotoxic, immunosuppressive drug would be strongly
recommended.
At present, the best choice would be oral cyclophosphamide or the
antipyrimidine drug Arava® (leflunomide). which should be started at a low
dosage of 1 mg/kg/day because of the patient's neutropenia. This dosage could be
increased to a maximum of 2.5 mg/kg/day if her blood cell counts become more
stable. Close monitoring of blood cell counts would be required. The white cell
count should not be allowed to drop below 3000/mL and the neutrophil count
should not fall below 1000/mL. Cyclophosphamide dose should be decreased if
her counts drop and her CBC is monitoried closely.
low dose of oral prednisolone 5 to 10 mg daily would be recommended. The
patient's blood glucose should be monitored for the need to control her iatrogenic
diabetes mellitus.
If her hyperglycemia persists, insulin would be started and insulin dose will be
adjusted depending on her blood sugar levels.

circumstances?

Questions And Comments About The Case Study
Q#1 : How should this patient managed ?
Corticosteroids are associated with many adverse effects including fluid and
electrolytes disturbances, hyperglycaemia, glycosuria, increased susceptibility to
infections, osteoporosis, cataracts, mood changes, and increased occurrence of peptic
ulcer. The increased risk of peptic ulceration associated with corticosteroids occures
for example with total doses of 1g prednisolone given over 30 days or less, with
patient receiving less than 15 mg prednisolone per day having a sinificantly decreased
rate of ulcer formation.
It would be inappropriate to routinely prescribe prophylaxis to all patients receiving
corticosteroids. However, in geriatrics taking NSAID’s it is important to prescribe a
prophylaxis therapy.
******************************
Q#2 : How should this patient be managed ?
It will be necessary to stop the NSAID’s because of the gastric bleed. The patient
should rest and receive simple analgesics regularly with intra-articular ateroids
injections in the affected joints. The patient should continue her prednisolone. In view
of the gastric bleed.
The patient must take PPI like omeprazole ( 20 mg daily ).
The patient blood result show an iron deficiency anemia ( low Hb, MCV, MCHC )
The patient should receive oral ferrous sulphate ( 200 mg 8-hourly ). After 10 days of
reticulocyte count should be taken to ensure that the iron is being absorbed and thus
the the patient’s anemia is being corrected. The patient Hb level should rise by 2 g
every 3 weeks.

Q#3 : Would topical NSAID’s be of any use to this patient ?
The effeciency of topical NSAID’s remains poorly defined mainly because of the
difficulty in measuring response. The topical preparations are expensive when
compaired to rubifacients.
Topical NSAID’s are designed to present a high concentration of the locally applied
agent to the joints with minimal systemic effects. The topical NSAID’s have been
associated with fewer side effects than systemic NSAID’s

Questions And Comments About The Case Study
Q#1: What are the treatment options for this patient ?
As this patient has had response to sulphasalazine and is experiencing no particular
problems with its use, there is a good argument for the co-prescription of a second
DMARD. Methotrexate is more effective than other DMARD such as gold and
hydroxychloroquine, and has low discontinuation rate. There seems little to be gained
by stopping sulphasalazine, and the addition of a DMARD with a different site and
mode of action may give an additive or even synergistic effect. The combination of
sulphasalazine and methotrexate has been shown to be effective and well tolerated.
***************************************
Q#2: What baseline data should be collected if
methotrexate therapy were to be commenced ?
Before starting Methotrexate therapy a full blood count should be taken, serum
albumin and the renal and liver functions due to the risk of liver damage with
methotrexate therapy. Methotexate should be avoided as much as possible if the
patient is alcoholic. Also this drug should be avoided in case of having
abnormal lver function or evidence of chronic viral hepatitis.
**************************************************

Q#3: How is Methotrexate initiated and when should a
response to methotrexate be expected ?
Methotrexate should be initiated at a dose of ( 7.5mg in one day each week ).
Mr.P.B should be counseled to take this on the same day and preferably at the same
time to avoid potentially serious administration errors. Folic Acid possibly at the dose
of (5mg twice a week ) and not on the methotrexate day, should also be started to
reduce the severity of side effects. At 4-8 weekly intervals,the dose should be
increased by 2.5 mg per week depending on patient tolerance. As Mr P.B is on
sulphasalazine it maybe appropriate to aim for a maximum maintenance dose of
( 15mg weekly rather than 20 to 25 mg ). The patient could expect to see some
improvement in symptoms 4-6 weks after the addition of methotrexate. The maximal
response would be after 3 months, depending on how quickly the dose was increased.
*************************************
Q#4: What treatment options are there to correct low
WBCs count that can be associated with methotrexate?
Leucovorin rescue is useful as the first line treatment. It is used to diminish the
toxicity and counteract the folic acid antagonistic action of methotrexate. The dosage
depends on the severity of the leucopenia. In general, up to 150 mg is usually given in
individual doses over 12-24 hrs by IM injection, IV bolus or infusion. Measures to
ensure prompt excretion of methotrexate are also important, and include alkalinization
of urine to above pH 7.0 an dmaintenance of increased urine output. In cases where
leucopenia is severe, treatment with granulocyte colony-stimulating factor may be
required. It can include marked increase in peripheral blood neutrophil counts within
24 hrs of administration. A SC dose of 5 microgram/Kg/day may be given and should

be continued until the neutrophil count has reached and can be maintained at more
than 1.5 *10 9/L.

Case Study # 4
PATIENT HISTORY:
The patient is a 52 year old woman with a recent history of myocardial infarction, and
a long standing history of rheumatoid arthritis with severe joint deformities in both
hands, including a gangrenous left fifth digit. She also has a history of multiple deep
venous thromboses of the lower extremities. A vague history of possible systemic
lupus erythematosus is also reported (constituting a possible mixed connective tissue
disorder). She is on multiple medications, including Coumadin and hydrocortisone
(100 mg every 8 hours) for her joint disease. The patient has a long history The
patient has a long history of borderline adrenal gland insufficiency,, which is likely a
result of the chronic administration of systemic steroids. She presents to the hospital
with complaints of fatigue and is noted to be anemic on complete blood count, which
reveals a hemoglobin of 8.1 with a hematocrit of 23.9. A rectal exam is guaiac
positive for blood. The patient is scheduled for colonoscopy to evaluate the source of
the gastrointestinal bleeding.
COLONOSCOPIC FINDINGS:
Colonoscopy demonstrates diffuse vascular nti-inf lesions from the level of the midtransverse colon to the cecum. Multiple diffuse vascular lesions are noted in the right
hemicolon, including the cecum, ascending colon and proximal transverse colon.
Although no active bleeding is noted at the time of colonoscopy, these lesions are
thought to represent the most probable source of the heme positivity in the stool.
Etiologies which are considered for the lesions evaluated endoscopically include
vasculitis, arteriovenous malformations, angiodysplasia, or lesions of cytomegalovirus

infection. Two biopsies are procured from the right colon; one is sent for
histopathologic study, and the second is sent for CMV studies. CMV is not detected in
these subsequent studies.
Section lll
GROSS DESCRIPTION:
The specimen is received in formalin and consists of an irregularly shaped fragment
of tan-pink mucosal tissue measuring 0.1 cm in greatest dimension.
Microscopic Discripyions :
The biopsy specimen consists of a portion of cecal mucosa with a portion of
underlying submucosa with several larger submucosal vessels. Examination of the
surface of the biopsy demonstrates colonic epithelium with goblet cells and
moderately distorted crypts. Some areas of the lamina propria are expanded by a
moderate number of lymphoid cells with admixed plasma cells. Other areas of the
lamina propria demonstrate focal hemorrhage, and collections of neutrophils and
probable fragments of nuclear debris. Examination of the submucosa reveals edema
and numerous small vessels which display varying amounts of neutrophilic infiltration
and destruction of the vascular wall. Some of the vessels demonstrate tortuosity and
occlusion by a combination of neutrophils, thrombosis, nuclear debris, and
eosinophilic necrosis of the vessel wall. In the deepest portion of the biopsy, a
thickened, tortuous, moderately fibrotic vessel is noted, suggesting a chronic
vasculitic/inflammatory process.

Section lll
Contributor’s Note:
Systemic lupus erythematosus (SLE) is an autoimmune disorder seen predominantly
in women of childbearing age (approximately 9:1 male:female ratio), in which there is
a primary defect in the discrimination of self versus non-self antigens by the immune
system. Various antibodies with self-directed specificity have been described and are
considered diagnostic of SLE when in combination and in the appropriate clinical
setting. Clinically, SLE commonly manifests in a myriad of systemic abnormalities,
including skin rashes, polyarticular arthritis and myalgias, renal dysfunction, weight
loss with fatigue, coagulation and other hematologic abnormalities, serositis involving
heart and lungs, and localized or systemic vasculitides (as mentioned above). At least
one group has correlated the rise in the serum of complement split products with
increased risk of small vessel vasculitis in SLE patients (Abramson et al).
As a group, the self-directed immunoglobulins in SLE are referred to as anti-nuclear
antibodies (ANA), noted in greater than 95% of SLE cases. Major subtypes include
anti-double stranded DNA antibody (directed towards ds DNA in patient cells, with
their subsequent destruction); anti-Smith (directed against core proteins in the small
nuclear ribosomal complex); anti-histone antibodies, and anti-ribonucleoprotein
antibodies (U1RNP). Although these and other antibodies can be seen in other
autoimmune disorders (such as systemic sclerosis and Sjögren’s syndrome), the
combination of the proper clinical features with the presence of anti-ds DNA and antiSmith antibody is considered virtually diagnostic of SLE. The course of the disease is
variable, with a usual chronic course that tends to respond to
nti-inflammatory
therapy in the event of periods of disease exacerbation. If patients with SLE succumb
to their disease, the most common causes of death are renal failure and infections
(often secondary to long term immunosuppressive therapy).
Secondary vasculitides in patients with primary autoimmune disorders, such as
systemic lupus erythematosus and rheumatoid arthritis, are a well-recognized

phenomenon. Although most commonly found to involve the small venules of the
skin and subcutaneous tissue, a more severe systemic vasculitis, clinically
indistinguishable from the polyarteritis nodosa group (PAN) can be seen. These
Section lll
variants are characterized by an often necrotizing leukocytoclastic vasculitis of
systemic small to medium-sized muscular arteries which can affect any system or
region. As in classic PAN, however, renal, musculoskeletal, and gastrointestinal
arteries are most commonly involved. The presentation of the case described above is
unusually florid, with diffuse vascular changes by endoscopy in the right colon,
gangrenous changes in a digit (which may represent either severe Raynaud’s
phenomenon, as noted in many SLE patients, or localized vasculitis with attendant
thrombosis of the vessels supplying the digit), a history of deep venous thromboses,
and coronary artery disease (which may or may not be related to the patient’s
autoimmune
disease).

Case Study # 5
History
The patient is a 60 year old Hispanic female with a recent diagnosis of Rheumatoid
Arthritis, brought to this tertiary care referral center by her daughters who reported a 2
month history of worsening cognitive difficulty and decreased arousal since the
patient fell from a chair.
Two and a half years ago the patient began to lose weight. She initially experienced a
rapid loss of weight from 160 to 130 pounds, but has continued to lose weight to the
point where she now weighs 116 pounds. About nine months ago, her daughters
noticed a raised bilateral rash on her feet and lower extremities with residual
hyperpigmentation of her feet and the distal portion of her legs. Six months prior to
her current presentation, she developed joint pains and subcutaneous nodules.
Diagnostic evaluation at that time revealed a Rheumatoid Factor titer of 1:1260 and
an ANA of 1:160, homogeneous pattern with an elevated ESR. She was diagnosed
with Rheumatoid Arthritis and has since been treated with regimens of non-steroidal
medications and immunosuppresive therapy. At the time of evaluation her current
regimen was Plaquenil and Prednisone.
Four months earlier she was noted by her Rheumatologist to experience gait
difficulties with "falling episodes". During this time, she is also noted to have
occasional fever and chills. A diagnosis of Diabetes Mellitus was presumed secondary
to steroid therapy. A remote reference to a diagnosis of Felty's is also mentioned in
progress notes reviewed during this time frame. Two months prior to presentation, she
fell from a chair and has had rapid progressive decline in mental status since that time.
The family denies prior significant illnesses or disease.

Section lll
Comments:
Juvenile rheumatoid arthritis, known as juvenile chronic arthritis in Europe, is the
most common rheumatic disease in children. Criteria for diagnosis include age of
onset less than 16 years, disease duration greater than six weeks, arthritis, and
exclusion of other forms of juvenile arthritis. Juvenile rheumatoid arthritis is
subdivided into pauciarticular (less than five joints involved), polyarticular (five or
greater joints involved), and systemic (arthritis, fever and rash) forms.
Skin manifestations of juvenile rheumatoid arthritis include amyloiosis which occurs
in one to ten percent of all subtypes. Ninety percent of systemic-onset juvenile
rheumatoid arthritis is characterized by an evanescent salmon-covered eruption that
occurs on the trunk and thighs and which is concurrent with fever. The eruption may
be elicited by scratching, ie, the Koebner phenomenon. A variant of juvenile
rheumatoid arthritis with onset in young adulthood is adult Still's disease, which
occurs at ages 16 to 35, is characterized by multi-system involvement and an
evanescent, salmon-pink, macular and papular eruption, and is accompanied by fever.
The eruption occurs on the trunk and proximal extremities and may be elicited by the
Koebner phenomenon.
The skin manifestations of rheumatoid arthritis include rheumatoid nodules,
rheumatoid papules, rheumatoid neutrophilic dermatitis, and vasculitis. Rheumatoid
nodules are subcutaneous nodules that occur in 20 percent of rheumatoid patients with
positive rheumatoid factors, and rarely in seronegative patients. The nodules generally
correlate with disease activity. Rheumatoid nodulosis (multiple, widespread nodules)
is a separate entity that occurs mostly in men with a low-grade fever and mild
synovitis. Nodules develop most commonly on pressure areas, such as the elbows,
joints, ischial and sacral prominences, along tendons, and the occiput. In general,
nodules regress with treatment as the rheumatoid arthritis improves. Rheumatoid

Case Study # 7
Case Report:
An 11-year-old girl, was brought with the complaints of progressively worsening
stiffness and restriction of movements of all joints, associated with increasing
difficulty in walking, and inability to close hands into a fist. She was the product of a
non-consanguineous marriage; her mother was 24 years and father 30 years old. She
was the second of three sibs, all of whom were normal. There was no history of a
similar illness in any family member.. She developed normally both physically and
mentally till the age of 3 years, when she was noted to walk with her right leg and
foot turned outwards. Within a year she developed knock knees as well. She also had
complaints of being tired easily following exertion, difficulty in getting up from the
squatting position and climbing stairs. The difficulty appeared to be related to the
developing abnormality of the joints as well as to muscular weakness. At age five
years she developed increasing stiffness of her joints which progressed to a marked
restriction of movements of many of her joints namely elbows, wrists, small joints of
hands and feet, hip, knee, ankle and neck at the time of presentation. There was no
history of fever, joint pains or fractures.
She had been worked up elsewhere, and been given provisional diagnoses of rheumatoid arthritis, rickets, mucopolysaccharidosis and metaphyseal dysplasia; treatments
received were high doses of Vitamin D, anti-inflammatory drugs and steroids at
different points of time, without any significant relief.

On examination, she was thin built, height was 120 centimetres falling below the 5th
centile for her age, upper segment was 60 centimeres (upper segment = lower
segment) and arm span-125 centimaetres (more than height). Vitals were within
normal limits. She had a dysmorphic face with a mild depression of the nasal bridge,
flattened nose, everted nostrils, hypoplastic maxilla and a prominent pouting mouth,
giving a leonine appearance (Fig. 1). There were no corneal opacities.
Facial appearance of

Examination of the musculoskeletal system examination showed widening of the
elbows, wrists, knees and interphalangeal joints of the hands and feet. Movements of
all joints were restricted, including neck and spine (with loss of lumbar lordosis),
shoulder, elbow, wrist, knee, ankle and small joints of hands and feet, the restriction
being maximum in the distal joints as compared to the proximal joints. The widening
and fixed flexion deformity of the metacarpophalangeal and interphalangeal joints of
the hands gave the hands a claw like appearance. There was also coxa-vara and genu
valgum. There were no bony deformities or pain or tenderness of any of the joints.
Gait was waddling and because of stiffness of all joints, like a puppet.
Examination of central nervous system showed normal higher functions with IQ 90.
Cranial nerves were normal. There was wasting of all muscles of hands and feet; tone
and power could not be tested properly in view of the stiffness of all the joints. The
deep tendon jerks were normal. Other neurological parameters were normal.
Abdominal examina-tion did not reveal any hepatosplenomegaly, and the
cardiovascular and respiratory systems were unreamarkable.

PPAC is an autosomal recessive dis-order(6); the gene has been localised recently to
chromosome 6q22(7,8). The etiopatho-genesis is not clear, but it has been shown to
be primarily a disorder of the articular cartilage. Histological studies show a peculiar
nest like clustering of the chondrocytes in the resting and growth cartilage(1). Various
treatment modalities have been tried, but none have proven effective till date. The
disease is relentlessly progressive and leads to severe difficulties in ambulation and

activities of daily living. No reports are available on the ultimate outcome of these
patients since this is a relatively new disease.
Slowly progressive restriction of move-ments of all the joints starting between 3-8
years age, associated with widening of the joints but no pain or tenderness, should
raise the suspicion of PPAC. However, it is an uncommon condition not widely
Section lll
known, and frequently misdiagnosed. Spranger et al.(1) in their five cases reported
that one patient was given various diagnoses including rheumatoid arthritis,
polymyositis, endochondral dysosto-sis and Morquio disease, while another received
the diagnosis of endochondral dysostosis. Our patient also reported to us with
diagnoses of rickets, rheumatoid arthritis and MPS having been made elsewhere.
Normal calcium, phosphorus and alkaline phospaha-tase, and absence of
characteristic changes of rickets on X-rays of wrists and ankles excluded rickets,
while a normal ESR, negative rheu-matoid factor, absence of fever, pain and
tenderness ruled out rheumatoid arthritis. In view of the coarse facial features, short
stature and skeletal abnormalities and normal IQ, Morquio disease was a likely
possibility and a skeletal survey was ordered to look for bony changes of MPS.
The X-rays however showed up the pathognomonic changes of PPAC(9,10). In view
of the difficulty in early clinical diagnosis of the disease, it is imperative that
radiologists be familiar with radiographic features of the disease in order to avoid
needless investigations and trials of medication. The characteristic radiographic
features are narrow joint space with wide metaphyses and flat epiphyses. Femoral
heads are enlarged and acetabulae are irregular. Platyspondyly with erosion of end
plates is present. This condition mimics juvenile rheumatoid arthritis but bony
changes show joint space narrowing, over-growth of epiphyses and osteopenia, which
are not seen in PPAV. This condition should also be differentiated from
spondyloepiphyseal dysplasia congenita, in which the extremities are normal; from
spondyloepiphyseal dysplasia tarda, where the patient has a characteristic dorsal
hump and spondylo-metaphyseal dysplasia in which epiphyses are not affected and
joint stiffness is not present.

Though our patient showed all the classic clinical and radiological features of PPAC,
the facial dysmorphism was misleading. Such facies have not been reported in
association with PPAC earlier. Another hitherto un-reported feature in our patient was
the arm span being greater than the height. A reduction of measured standing height
may occur due to flexion deformities at the hips; however the flexion at the hips was

Case Study # 8
HISTORY:
This is a 7 year old girl lives with her parents who has had polyarticular JRA for over
a year. Most recent management has been with prednisone, methotrexate and tolectin.
The symptoms improved with little evidence of ongoing synovitis. A mass in the left
bicipital area was first noticed at the age of 7 years and 9 months.
PHYSICAL EXAM:
The mass was firm, located in the antero-medial aspect of the left upper arm and was
difficult to separate from the biceps. It did not transilluminate. Shoulder ROM was
full.
SONOGRAM AND XRAYS:
The sonogram showed a solid soft tissue mass which was fairly homogeneous in
echo-genicity, and well defined with minimal vascularity. No connection with the
shoulder joint was observed. MRI with gadolinium showed a mixed density collection
which appeared to have a narrow connection with the shoulder joint. An arthrogram

Rheumatoid Arthritis
of the left shoulder joint demonstrated extension of dye down the bicipital groove and
into the mass in the upper arm. The mass was more palpable after the arthrogram. We
concluded that the mass was a synovial cyst due to chronic synovitis.
FOLLOW-UP:
The synovial cyst has resolved spontaneously and has not recurred over 3-months
follow-up.

Questions And Comments About The Case Study
Q#1: What is the role of Cyclophosphamide and
methylprednisolone in the management of this patient?
Cyclophosphamide and methylprednisolone have been used effectively in rheumatoid
vasculitis for their potent immunosuppressive actions. Regimens do vary, but
intravenous pulses every 4 to 6 weeks are often used in rheumatology centers.
Methylprednisolone at a dose of ( 500 mg to 1 g over an hour or more to prevent
cardiac arrhythmia or ischemia ) gives a rapid and intense anti-inflammatory action
as well as immunosuppressive activity. .Once the condition improves, oral steroids
may be considered. Such a improvement may be seen by monitoring laboratory
indices such as ESR, renal function and urine protein content. Cyclophosphamide ( a
Yosra Ashraf
53
Rheumatoid Arthritis
cytotoxic agent ) may either be given as a slow IV bouls foe a short IV infusion, at a
dosage range of 7.5 to 12.5 mg/kg depending on the patient’s condition and renal
function. Patient usually tolerate cyclophosphamide well although prophylactic
antiemetics should be given and the possibility of fertility suppression should be
discussed with patients.
*************************************
Q#2: What precautions should be taken with
cyclophosphamide?
Prior to administration of cyclophosphamide, patients should have a full blood count,
urea and electrolytes, and creatinine measured. Also, a full medical examination
should be carried out to exclude intercurrent illness or evidence of infection.
Section lll
A high fluid intake ( at least 2.5 L on the infusion day ) should be maintained to
reduce the risk of haemorrhagic cystitis, possibly with the edition of IV fluids.
Mesna ( Uromitexan ) is sometimes also given, although there is little clinical
evidence

cyclophosphamide unlikely to be serious if infusion is promptly discontinued, and
ward staff should be familiar with the extravasation procedure.
*********************************
Q#3: What other treatment options are available for this
patient?
Administration of Epoprostenol or Iloprost has been used in rheumatoid vasculitis to
improve vasculitic ulcers and reduce peripheral ischemia. Neither is license in this
condition, and iloprost is available only no a named patient basis at present. Both are

forms of prostacyclin wich is a potent vasodilator and inhibitor of platelete
aggregation. These are given either as IV infusions over 8 to 12 hours for 3 to 6 days
or, in severe peripheral ischemia, as a continuous 24 hou infusion for up to 5 days.
Infusion rates are titrated according to patient response and tolerance. Pulse and blood
pressure should be monitored regularly at first as hypotension occurs (withhold any
medication that might potentiate this , eg. Nifedipine ).

Clinical Problem
This is the radiograph of a 60 year old married lady with chronic rheumatoid arthritis
who presented to us with problems 4 weeks after left total elbow arthroplasty. She had
a similar procedure performed on the opposite side without problem. One week after
this surgery she felt a “clunk” in her elbow and then had difficulty moving it without
discomfort. Radiographs showed the elbow had dislocated. A closed reduction was
performed, but 2 weeks later the dislocation recurred. Open reduction and a soft tissue
reconstruction was performed at that time. Now the elbow is again dislocated, swollen
and painful on all motion – she keeps it in a splint at all times. Her lateral elbow
incision is relatively calm, but the sutures are still in place. She has had two surgeries
and one manipulation in less than one month. Her exam indicates ulnar nerve

Open reduction was attempted after ulnar nerve dissection through a new

constrained total elbow was accomplished with minor penetrations of ulna and
humerus in process of cement removal. Post operative range was 0-135 degrees.

Important additional practice points :
Yosra Ashraf
58
Rheumatoid Arthritis
Treatment of RA should begin as soon as possible, as there is evidence that most
patients will develop bone erosions within the first 2 years of their disease. Such
early treatment maybe realized by the use of early arthritis clinics in which
patients are seen within 2 weeks of referral from their general practitioner.
There is a new gene therapy for Rheumatic diseases.
Patients with RA may be highly susceptible to TB.
Starting RA treatment early saves money quickly.
People setting in smoking places and women are at risk for developing
Rheumatoid Arthritis.
Patient education only part of a good RA management program.
Multiple DMARD therapy may offer advantages over single-drug regimens.
An episode of depression can have a life-long influence on RA pain and disability

Pharmacoeconomics
Yosra Ashraf
59
Rheumatoid Arthritis
Pharmacoeconomics is the science of demonstrating the
balance between costs and consequences of drug therapy.
Outcomes research is concerned with evaluating the effects of medical intervention on
clinical, economic and humanistic measures.
Pharmacoeconomics of NSAIDs: Beyond Bleeds
OBJECTIVE:
To determine the marginal effect of including a minor, yet common, gastrointestinal
(GI) side effect in a cost effectiveness analysis of NSAID therapy.
DESIGN:
Base economic model of cost effectiveness analysis (CEA) developed using data from
a randomized controlled trial of two formulations of an NSAID therapy (conventional
versus extended release etodolac) for the treatment of osteoarthritis (OA) of the knee.
Section
INTERVENTIONS:
Patients were randomized to receive either conventional or extended release etodolac
with primary endpoints evaluated at four weeks. Cost effectiveness was calculated
from a managed care perspective as dollars spent per OA patient treated, focusing on
the marginal dollar value of reduced side effects. Costs included in the analysis were
Yosra Ashraf
60
Rheumatoid Arthritis
initial ($64 or $71) and subsequent ($64) prescriptions for NSAID therapy,
pharmacological treatment of side effects ($79), and physician office visits ($50).
MAIN OUTCOME MEASURES:
Percent reduction in dyspepsia, average cost per OA patient treated.
RESULTS:
Reduced instances of dyspepsia, a common side effect of NSAID therapy, from 20%
to 8% resulted in an estimated marginal cost savings to the insurer of $14 per patient
switched from conventional to extended release etodolac. In addition, there were cost
savings to the patient in terms of reduced out-of-pocket expenses. A more favorable
side-effect profile also may assist in improving patient compliance.
CONCLUSION:
The marginal effect of including common GI side effects in a CEA of NSAIDs may
have important economic implications for managed care providers. While ulceration
and bleeds are the most serious and costly side effects associated with NSAID
therapy, it is important to consider other positive and negative outcomes associated
with therapy when performing a pharmacoeconomic evaluation.
