The role of CYFRA 21-1, nucleosome and neurone-specific enolase as early measures of chemotherapy response in non-small cell lung cancer Mohamed A. Alm El-Din, M.D.,* Ayman Abd El-Zaher, M.D.,§ Hala Nagy, M.D.,‡ Gihan Farouk, M.D.,‡ Gehan H. Abo El-Magd, M.D. § Departments of Clinical Oncology, * Clinical Pathology, ‡ and Chest § Tanta Faculty of Medicine, Tanta, Egypt Abstract: Background: To investigate the decline in the level of cytokeratin-19 fragments (CYFRA 21-1), nucleosomes and Neurone specific enolase (NSE) as an early indication of response to chemotherapy in lung cancer. Methods: Forty-two consecutive patients with locally advanced non-small cell lung cancer were included. All patients received platinum-based chemotherapy. Staging investigations and assay of CYFRA 21-1, nucleosomes and NSE using enzyme linked immunosorbent assay (ELISA) were done before the start of treatment and after the second cycle of chemotherapy. According to response to chemotherapy, patients were classified into three groups: regressive disease (group I), stable disease (group II) and progressive disease (group III). The decline of tumour markers was correlated to the response to chemotherapy. Results: After the second dose of chemotherapy, Group I and II had significant decrease in the level of CYFRA 21-1 (P < 0.05). Also, the concentration of nucleosomes was significantly lower as compared to the baseline level in group I and II (P 0.0008 and 0.003, respectively). The decline in both CYFRA 21-1 and nucleosomes was not significant for patients with progressive disease (group III). The level of NSE showed insignificant decline in response to chemotherapy in all groups. As an indication for response to chemotherapy, CYFRA 21-1 showed the highest sensitivity and specificity compared to nucleosomes and NSE (88.9, 77.4 vs. 77.8, 58.1 and 66.7, 51.8, respectively). Conclusion: The decline in the serum level of CYFRA 21–1 and nucleosomes may be used in early identification of patients with good response to chemotherapy. The relationships between CD14 and CC16 genotypes, plasma levels, & severity in acute asthma patients Ayman H. Abd El-Zaher1, Heba Mourad 2, Amal EL-Bandary 2, Hala M. Nagy 2, and Waleed Samy 3 Departments of Chest1, Clinical Pathology 2 and Internal Medicine 3 Faculty of Medicine, Tanta University, Egypt Abstract: Background: Acute asthma is characterized by acute episodes of obstruction related to airway inflammation mostly in response to respiratory tract infection. CD14 and Clara cell protein (CC16) play a key role in inflammatory pathways. Objective: The aim of this study is to determine the influence of CD14 and CC16 gene polymorphism and plasma levels of their products on the predisposition to develop asthma and its severity. Methods: This study was conducted on 40 patients during acute attack of asthma (group I) and in convalescence (after 6 weeks of treatment of the same patients, group II). Asthma severity scoring system was preformed to all patients according to (Martin et al; 2006). Arterial blood gases, plasma levels of sCD14, CC16 and serum total IgE were measured by ELISA. CD14 and CC16 gene polymorphism were detected by restriction fragment polymorphism (RFLP). Results: During acute asthma, plasma level of sCD14 and CC16 were significantly higher than during convalescence: sCD14, 3.23±0.48 versus 2.64±0.24 µg/ml, (p= 0.001); CC16, 2.52±0.33/m versus 1.76±0.22 µg/ml, (p= 0.002). Higher plasma levels of sCD14 were present during the acute attack in those with 159TT and 159TC (p= 0.002 & p= 0.001, respectively), whereas in 159CC homozygous, sCD14 levels were insignificantly increase during the acute attacks (p= 0.119). Also higher plasma levels of CC16 were present during the acute attack in those with 38GG and 38AG (p= 0.001 & p=0.002, respectively), whereas in 38AA homozygous, CC16 levels were actually lower during the acute attacks than during convalescence, although this difference was not statistically significant (p= 0.093). A significant negative correlation was found between sCD14 and asthma score (r= 00.58, p= 0.001), while a insignificant positive correlation was found between CC16 and asthma score (r= 0.0243, p= 0.13). There was a significant positive correlation between IgE and plasma level of sCD14, CC16 and asthma score. Conclusion: These results suggest that in acute asthma production of both sCD14 and CC16 is increased in an attempt to control airway inflammation, and for subjects whose genotype limits or prevents these increases, the ability to control airway inflammation is impaired resulting in more severe asthma. Therefore, this study supports the concept that sequence variations in the CD14, CC16 gene are likely to play a role in the development of asthma. Effect of a disintegrin and metalloprotease 33 (ADAM33) gene polymorphisms & smoking in COPD Ayman H. Abd El-Zaher*, Hala Nagy**, Gihan Farouk**, Ahmed Sh. Mohamed* & Naglaa F. Ghoname*** Departments of Chest*, Clinical Pathology** and Microbiology & Immunology*** Faculty of Medicine, Tanta University, Egypt Abstract: Background: COPD is characterized by air flow limitation that is not fully reversed and associated with an influx of neutrophils, macrophages and CD8 T lymphocytes in the airways. The disease is characterized by airflow limitation and is associated with an abnormal inflammatory response of the lungs in response to noxious particles or gases and associated with systemic manifestation. Methods: 60 consecutive patients with COPD and 40 normal healthy individuals were included. All cases and controls were subjected to detection of 2 polymorphic loci (S1 AND Q1) of ADAM33 by PCR-RFLP technique. Results: The percentage of S1 and Q1 AA genotype and A allele were significantly increased in control than in COPD patients while there was significant increase in S1 and Q1 GG genotype and G allele in COPD patients than in control (p<0.001). no significant difference was found between smoker and non-smoker among the two studied groups in genotype and alleles distribution of ADAM33 SNPs S1 and Q1 p>0.05, whereas there was significant increase in ADAM33 S1 G allele and Q1 G allele in smoker and non-smoker in COPD patients as compared to their corresponding fellows in control group ( p<0.05). As regard to Pulmonary function test there was significant decrease in % of FEV1 in COPD patients as compared to control group for both smokers and non-smokers (p<0.001). Within both control and COPD groups smokers had significant decrease in FEV1% as compared to nonsmokers (p<0.001). There was a significant decrease in FEV1% among all genotypes in smoker as compared to non-smoker COPD patients (p<0.001), the most prominent decrease was found in smoker GG genotype for both ADAM33 S1 and Q1 in COPD patients. Conclusion: We found that polymorphisms in the SNPs (Q1 and S1) of ADAM33 gene are associated with COPD in the general population. In addition, smoker patients with GG genotype in (S1 and Q1) ADAM33 will have more pronounced decline in the pulmonary function test (FEV1). Diagnostic utility of sonar guided biopsy in tuberculous effusion Ayman Abd El-Zaher1, Ibrahim Salah1, Mohamed Hantera1, Radwa Oreby2, Ebrahim Abaas3 Departments of Chest1, Pathology2 & Radiology, Faculty of Medicine, Tanta University, Egypt ABSTRACT Background /Aim: Tuberculous pleural effusion remains the commonest cause of exudative effusions in areas with a high prevalence of tuberculosis and histological examination of pleural tissue is the gold standard for its diagnosis. This study was to assess the dialogistic utility of sonar guided biopsy in tuberculous pleural effusion. Patients & Methods: 50 patients (34 men) of mean ± SD age 38.7±16.7 years with pleural effusions and a clinical suspicion of tuberculosis were enrolled in the study. Transthoracic ultrasound was performed on all patients, who were then randomly assigned to undergo ≥4 Abrams needle biopsies followed by ≥4 Tru-Cut needle biopsies or vice versa. Medical thoracoscopy was performed on cases with non-diagnostic closed biopsies. Results: Pleural tuberculosis was diagnosed in 31 patients, alternative diagnoses were established in 16 patients and 3 remained undiagnosed. Pleural biopsy specimens obtained with Abrams needles contained pleural tissue in 29 patients (92.0%) and were diagnostic for tuberculosis in 26 patients (sensitivity 82%), whereas Tru-Cut needle biopsy specimens only contained pleural tissue in 21 patients (78%) and were diagnostic in 21 patients (sensitivity 64%). Conclusions: Ultrasound-assisted pleural biopsies performed with an Abrams needle are more likely to contain pleura and have a significantly higher diagnostic sensitivity for pleural tuberculosis. Effect of obstructive sleep apnea syndrome on left ventricular function Mohamed G. El-Kholly*, Medhat M Ashmawy**, Ayman H Abd EL-Zaher* & Mahmoud EL-Shahat* Departments of Chest* & Cardiology**, Faculty of Medicine, Tanta University, Egypt Abstract Background: The link between OSAS, left ventricular dysfunction, and congestive heart failure is less known, although OSAS is frequent in both systolic and diastolic heart failure patients. Aim: To study left ventricular function in patients with obstructive sleep apnea syndrome & to assess the correlation between the severity of OSA and the degree of ventricular dysfunction. Subjects and Methods: This study was conducted on 45 subjects (22 males & 23 females) in Chest Department, Tanta University Hospitals, they were classified into 2 groups: Group A included 15 apparently healthy subjects, by sleep study they were normal as apnea hypopnea index (AHI) < 5/h and oxygen desaturation index (ODI) < 5/h. Group B included 30 patients with obstructive sleep apnea diagnosed by sleep study (AHI > 5/h & ODI > 5/h). Results: Eight (26.66%) out of the 30 OSAS patients (group B) were hypertensive and have left ventricular dysfunction. The mean value of AHI was (2.53±1.06) and (24.6±14.35) in group A and B respectively. The mean value of AHI was significantly higher in group B than group A (p = 0.001). Significant correlation was found between AHI, diastolic and systolic dysfunction respectively (r= 0.324; p= 0.019 and r=0.288; p=0.049) (figure 2, 3). Conclusion: Obstructive sleep apnea syndrome may predispose in left ventricular diastolic dysfunction, AHI is correlated with the degree of left ventricular diastolic dysfunction. Soluble triggering receptor expressed on myeloid cells -1 as differential biomarker of pleural effusion Ayman H. Abd El-Zaher*, Ali M. Abd-Ella*, Hala Nagy** & Raba Y. Talab* Departments of Chest* & Clinical Pathology** Faculty of Medicine, Tanta University, Egypt Abstract Background & Objective: The currently available diagnostic markers for pleural effusion have a limited role. The soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) is a molecule recently reported to play an important role in the myeloid cell mediated inflammatory response, and is up regulated in the body fluid by bacterial or fungal products. This study aimed to investigate the value and significances of sTREM-1 in the diagnosis of pleural effusion caused by different diseases entities. Methods: Samples of pleural fluid from 50 patients, (10 with empyema, 10 with para-pneumonic effusions, 10 with tuberculous effusion, 10 with malignant effusion and 10 with transudative effusion). Patients were assessed for the level of sTREM-1 by ELISA in pleural fluid. Total and differential cell count, LDH, glucose and protein were carried out to all studied patients. Results: Level of sTREM-1 was highest in empyema, followed by infectious exudates and the level of sTREM-1 were low in transudate and non-infectious exudates and there was positive correlation between sTREM-1 and (protein, total white blood cells and neutrophil % in pleural fluid) and serum LDH and negative correlation between sTREM-1 and lymphocyte % in pleural fluid. Conclusions: Our findings suggest a role for sTREM-1 in differentiation between infectious and non infectious pleural effusion. Medical thoracoscopy using fiberoptic broncoscopy Ayman Abd El-Zaher1, Mohamed Hantera1, Alaa Metwaly2 Dina Radi3 Departments of Chest, Tanta1 & Zakazeek Universities2 & Pathology Department3 Tanta University Abstract Background, Aim: Undiagnosed exudative pleural effusion remains a matter of interest in both clinical and research fields in chest practice. The evolution in methods of diagnosis started by Abrams closed biopsy then sonar guided closed biopsy then rigid thoracoscopy and lastly semi-rigid thoracoscopy and VATS, but what about centers without these facilities. The aim of this study is to assess the ability of fiberoptic broncoscopy through chest tube to replace rigid broncoscopy in diagnosis of undiagnosed exudative effusion. Patients and method: 20 patients with undiagnosed exudative pleural effusion were examined by fiberoptic broncoscopy through chest tube under local anaesthesia and biopsies were taken by forceps through working channels of broncoscopy. Results: Definite diagnosis established in 16 patients and 4 patients undiagnosed due to insufficient material, with no complications. Conclusions: Medical thoracoscopy using fiberoptic broncoscopy is safe manoeuvre and can replace rigid thoracoscopy in centers which cannot have. Assessment of sleep apnea in patients with liver cirrhosis Raafat A. Salah * & Ayman H Abd El Zaher ** Departments of Tropical * & Chest **, Faculty of Medicine, Tanta University, Egypt Abstract Objective: Patients with obstructive sleep apnea (OSA) are at risk for the development of fatty liver as a result being overweight. Several data suggest that OSA per se could be a risk factor of liver injury; ischemic hepatitis during OSA has been reported. Obstructive sleep apnea has been reported to be a new complication of liver cirrhosis with ascites. Therefore we investigated the episodes of sleep apnea as a complication of advanced liver cirrhosis. Methods: Sixty patients with liver cirrhosis due to chronic hepatitis C were divided according to the child-pugh score into 3 groups: Group A (20 patients grade A cirrhosis), Group B (20 patients grade B cirrhosis), and Group C (20 patients grade C cirrhosis). Portable sleep polygraph (ResMed corp., CA, USA) were attached to the subjects, and oronasal respiration, tracheal sounds, Respiratory movements of the chest, and percutenaous arterial oxygen saturation continuously were recorded. A decrease in the mean airflow to 50% or less was defined as hypopnea, and the number per hour of episodes of apnea and hypopnea per hour lasting 10 seconds or longer (AHI) was counted. Results: AHI was Results: AHI was significantly higher in Group C than in Groups A and B (p<0.05). In Group C, 6 patients with 20 times or more AHI per hour, obstructive sleep apnea, in which respiratory chest movements occur but oronasal respiration decreases or disappears, was observed. Conclusions: As the stage of liver cirrhosis advanced, sleep apnea appeared, and changes in autonomic nervous activities were observed. Role of granulocyte-colony stimulating factor in patients with idiopathic pulmonary fibrosis Waffa S. Al-Shimy*; Amgad A. Farhat*; Ayman H. Abd El-Zaher*; Hala M. Nagy**; Ghada A. Attia* & Ahmed M. Gamal Eldeen* Departments of Chest* & Clinical Pathology**, Faculty of Medicine, Tanta University, Egypt Abstract Background & objective: Idiopathic pulmonary fibrosis (IPF) is progressive lung disease with an associated mean survival 3-5 years. Granulocyte-colony stimulating factor (G-CSF) is known as a potent neutrophil chemotactic glycoprotein but its contribution to chemotactic activity in neutrophil mediated lung diseases is not yet known. The aim of this study was to determine level of G-CSF in bronchoalveolar lavage (BAL) fluid of patients with idiopathic pulmonary fibrosis and to correlate its level with neutrophil count in BAL fluid and the severity of the disease. Methods: the study was conducted on 40 subjects who classified into two groups; 10 healthy non-smokers subjects (control group) & 30 non-smokers IPF (patients group). BAL analysis was done for measurement of neutrophil count and G-CSF level using ELISA technique. Results: G-CSF in BAL of IPF patients was significantly higher compared to control group and it showed significant positive correlation with both neutrophil count in BAL & the severity of the disease. Neutrophil count in BAL of patients was significantly higher compared to control group. Conclusions: G-CSF has a high level in BAL of IPF patients & it correlates positively with severity of the disease.
