Background & objectives: Pleural effusion is a common occurrence in patients with late-stage chronic kidney disease (CKD). In developing countries, many effusions remain undiagnosed after pleural fluid analysis (PFA) and patients are empirically treated with antitubercular therapy. The aim of this study was to evaluate the role of adenosine deaminase (ADA), nucleic acid amplification tests (NAAT) and medical thoracoscopy in distinguishing tubercular and non-tubercular aetiologies in exudative pleural effusions complicating CKD. Methods: Consecutive stage 4 and 5 CKD patients with pleural effusions underwent PFA including ADA and PCR [65 kDa gene; multiplex (IS6110, protein antigen b, MPB64)]. Patients with exudative pleural effusion undiagnosed after PFA underwent medical thoracoscopy. Results: All 107 patients underwent thoracocentesis with 45 and 62 patients diagnosed as transudative and exudative pleural effusions, respectively. Twenty six of the 62 patients underwent medical thoracoscopy. Tuberculous pleurisy was diagnosed in six while uraemic pleuritis was diagnosed in 20 subjects. The sensitivity and specificity of pleural fluid ADA, 65 kDa gene PCR, and multiplex PCR were 66.7 and 90 per cent, 100 and 50 per cent, and 100 and 100 per cent, respectively. Thoracoscopy was associated with five complications in three patients. Interpretation & conclusions: Uraemia remains the most common cause of pleural effusion in CKD even in high TB prevalence country. Multiplex PCR and thoracoscopy are useful investigations in the diagnostic work-up of pleural effusions complicating CKD while the sensitivity and/or specificity of ADA and 65 kDa gene PCR is poor.

Background. Limited data are available from India on treatment outcomes with oral epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in newly diagnosed non-small cell lung cancer (NSCLC). We studied the demographic profile and treatment outcomes of patients with NSCLC, receiving first-line treatment with oral EGFR-TKIs. Methods. Retrospective study of newly diagnosed NSCLC patients treated with oral EGFR-TKIs over a 4-year period at a tertiary care institute in North India. Results. Of 76 patients studied, females and non-smokers constituted 32.9% and 48.7%, respectively. Majority of patients had adenocarcinoma (59.2%), stage IV (64.5%) disease and Karnofsky performance status <70 (74.5%). Gefitinib was the most frequently used EGFR-TKI (92.1%). Most common indication for the use of EGFR-TKIs was poor performance status (65.8%). Among assessable patients, disease control and progressive disease were evident in 66% and 34%, respectively. Most common side effects were skin rash (17%) and diarrhoea (10.6%). Patients with and without skin rash differed significantly in relation to objective response to treatment (100% versus 23.1%) and overall survival (median not reached versus 178 days). On multivariate logistic regression analysis, malignant pleural effusion was associated with occurrence of rash (odds ratio=0.19; 95% confidence interval = 0.04-0.95; p=0.04). Conclusions. Oral EGFR-TKIs appear to be useful for the treatment of clinically selected patients with advanced NSCLC. Occurrence of skin rash was independently associated with treatment response and better survival in the current study.

Background & objectives: Chemical pleurodesis is an accepted therapy for patients with recurrent pleural effusions and pneumothorax. Iodopovidone has been shown to be safe and effective for chemical pleurodesis in several studies. The aim of this systematic review was to update a previously reported meta-analysis on the efficacy and safety of iodopovidone pleurodesis. Methods: Two databases MEDLINE and EMBASE were searched for a period (1952-2010), and studies that have reported success rates with iodopovidone pleurodesis were selected. The proportions with 95 per cent confidence interval (CI) were calculated to assess the outcomes in the individual studies and the results were pooled using a random effects model. Results: Thirteen eligible studies with 499 patients were included in the mata-analysis. The success rates varied from 70 to 100 per cent in different studies with the pooled success rate being 88.7 per cent (95% CI, 84.1 to 92.1). The success rate was not affected by the method (tube thoracostomy vs. thoracoscopy, 89.6 vs. 94.2%) or the indication of pleurodesis (pleural effusion vs. pneumothorax, 89.2 vs. 94.9%). The only significant complication reported was chest pain of varying degree. Systemic hypotension was reported in six patients across the studies. There were no deaths associated with iodopovidone pleurodesis. Statistical heterogeneity and publication bias were found. Interpretation & conclusions: Iodopovidone may be considered a safe and effective agent for chemical pleurodesis in patients with pleural effusions and recurrent pneumothoraces.

Background. Transbronchial needle aspiration (TBNA) is an established procedure for sampling the mediastinal lymph nodes. Data reported from India are limited on this routine procedure. We describe our experience of the efficacy, diagnostic accuracy and safety of TBNA. Method. We retrospectively reviewed all TBNAs done at our centre between 2006 and 2009. Under local anaesthesia, accessible lymph node stations were sampled thrice without fluoroscopy and without an on-site cytopathologist. Data are presented in a descriptive manner. Results. A total of 4513 diagnostic bronchoscopies were done, of which 473 (10.5%) underwent TBNA. There were 297 men (63%) and 176 women (37%) with a mean (SD) age of 46.2 (13.98) years. The most common clinical diagnoses were sarcoidosis (50.5%), lung cancer (26.8%), tuberculosis (8.7%) and others (14%). The overall efficacy of TBNA in sampling a mediastinal/hilar lymph node was 72%. The accuracy of TBNA in achieving a pathological diagnosis was 40.4%, whereas the diagnostic yield of a successful procedure was 56.8% (lymph nodes were successfully sampled in 193 of 340 procedures). The most common diagnoses on cytology were sarcoidosis and lung cancer. In patients with a clinical diagnosis of lung cancer, the diagnostic accuracy of TBNA was 46.5% (59 of 127), whereas in patients with sarcoidosis it was 38.1% (91 of 239). TBNA provided an additional diagnostic yield in 5.6% (12 of 215) of patients with sarcoidosis who also underwent transbronchial lung biopsy. There were no periprocedural complications. Conclusion. Blind TBNA is a safe and effective procedure that can be routinely done in the bronchoscopy suite.

Background and Objective. There is little information on validated health-related quality of life (HRQoL) instruments for use in Indian patients with bronchial asthma. We attempted to validate the Hindi translation of Juniper’s mini asthma quality of life questionnaire (MiniAQLQ) in north Indian patients with bronchial asthma. Methods. Hindi translation of MiniAQLQ, and abbreviated World Health Organization quality of life questionnaire (WHOQOL-Bref), were administered to 30 patients with bronchial asthma twice at a six-week interval. Clinical and physiological data were also recorded. Psychometric properties (acceptability, validity, reliability and responsiveness) of MiniAQLQ were assessed after calculating four domain (physical, psychological, social relationships and environment), and a total score. Results. Most questionnaires were returned without missing responses. MiniAQLQ had good convergent and discriminant validity, but moderate content and construct validity. All components (except emotional function domain) met standards for internal consistency (Cronbach’s alpha coefficient >0.70), but intra-class correlation coefficients were variable. Change in MiniAQLQ scores between two assessments correlated poorly with corresponding changes in lung function. The effect sizes ranged from 0.02 to 0.34 in 11 patients whose forced expiratory volume in the first second (FEV1) changed by >200mL and >12% from baseline, and were considered small. Conclusion. The Hindi translation of MiniAQLQ is a moderately good discriminative and a relatively poor evaluative instrument to assess health related quality of life (HRQoL) in north Indian patients with bronchial asthma.

Initially described by a group of Japanese clinicians and pulmonary pathologists to distinguish it from other chronic obstructive lung diseases, diffuse panbronchiolitis (DPB) is an uncommon disorder which has been reported largely from the eastern world. It is imperative to recognise this condition because of its potentially treatable nature. Recently, long-term macrolide therapy has revolutionised its management. Herein, we describe a 65-year-old male who was being managed as a case of chronic bronchitis before this diagnosis was suspected and proved.

BACKGROUND: Limited information is available on epidemiology of spontaneous pneumothorax (SP) from India. The present study was aimed at studying aetiology and clinical profile of patients with SP. METHODS: All patients admitted at a tertiary care hospital with the diagnosis of SP between January 2001 and March 2002 were prospectively studied. Detailed demographic and clinical data were recorded. Patients were divided into two groups-primary spontaneous pneumothorax (PSP), if no underlying aetiology for pneumothorax was found, and secondary spontaneous pneumothorax (SSP), when an underlying respiratory disorder could be identified. The clinical features were compared between the two groups. RESULTS: Sixty patients (12 with PSP and 48 with SSP) were included in the study. Annual incidence of SP was calculated as 99.9 per 100,000 hospital admissions. Annual incidence figures for PSP and SSP were 20.0 and 80.0 per 100,000 hospital admissions respectively. Age distribution showed a biphasic pattern and the overall male to female ratio was 5 : 1. The most common cause of SSP was found to be pulmonary tuberculosis (41.7%). CONCLUSIONS: Pneumothorax is more common among men. In India, SSP is far more common than PSP, and the predominant underlying cause is pulmonary tuberculosis.

BACKGROUND AND AIMS: The search is on to find an easily measurable marker of disease activity in sarcoidosis. The present study was carried out to evaluate the utility of plasma D-dimer as a marker of disease activity in sarcoidosis. METHODS: Thirty newly diagnosed cases of sarcoidosis with clinical indications for treatment and an equal number of matched healthy controls were studied for the presence of D-dimers (DD) in the plasma before starting treatment with oral prednisolone and after clinical remission. Semi-quantitative estimations of DD were done using the latex agglutination slide test method (Commercial Kit - Diagnostica Stago, France) as per the manufacturer's recommendations. RESULTS: The mean age of cases and controls were 45.43 +/- 8.5 (range 34-60) and 46.16 +/- 8.07 (range 32-61) years, respectively. Of the 30 patients, nine (30%) were DD positive at baseline. The DD positive patients presented more often with dyspnoea, had radiological stage III (7 out of 9) disease and abnormal spirometry compared to patients with no detectable DD in their plasma. Of the 16 patients re-evaluated after clinical remission, eight (50%) were D-dimer positive. Two of the five patients initially DD positive had become negative and five additional patients who were negative at baseline had become positive. CONCLUSIONS: Plasma D-dimers, which were positive in 30% of untreated patients of sarcoidosis, indicate patients with significant pulmonary parenchymal involvement; but have no correlation with clinical disease remission.

OBJECTIVES: To determine the role of simple needle aspiration in the management of pneumothorax. DESIGN: All patients presenting with a pneumothorax requiring intervention were included in this prospective study. Patients who were very sick or had tension pneumothorax were treated with direct intercostal chest tube drainage (ICTD) and others were subjected to simple aspiration. The procedure was deemed successful, if after aspiration the lung expanded completely or symptoms were relieved with residual pneumothorax of less than 15% of hemithorax. In case of failed aspiration ICTD was carried out. RESULTS: Fifty-seven patients with 59 pneumothoraces were included in the study. Of these, 24 were treated with direct ICTD; 35 (12 spontaneous, 11 secondary and 12 iatrogenic pneumothoraces) were subjected to simple aspiration. Ten (83.3%) of the primary, 1 (9.6%) of the secondary and 11 (91.7%) of the iatrogenic pneumothoraces responded to simple aspiration. There were no significant complications. The pain perceived and the duration of hospital stay was significantly lesser in the simple aspiration group. CONCLUSIONS: Simple aspiration should be the initial modality of treatment for primary spontaneous and iatrogenic pneumothoraces. For secondary spontaneous pneumothorax and in conditions where pleurodesis is indicated, ICTD remains the treatment of choice.

Background: There is a need to re-assess the role of generally identifiable risk factors for development of tuberculosis (e.g. old age, poverty and poor socio-economic status). The present study was designed to look into the socio-economic and demographic characteristics of patients of tuberculosis (TB) vis-à-vis those with other respiratory diseases in the area in and around Chandigarh. Setting: Chest Clinic of a tertiary care hospital. Design: Case-control study Material and Methods: Two hundred and fifty consecutive cases of TB and an equal number of patients with pulmonary diseases other than tuberculosis as controls were interviewed as per a pre-designed, structured questionnaire that inquired into several socio-economic and demographic variables besides the clinical details. Univariate and multiple logistic regression analyses were carried out to obtain odds ratios separately for each variable. Results: The mean age of patients suffering from tuberculosis was 35.56 years (SD 13.69). There were 168 men (67.2%) and 82 (32.8%) women among the cases. Persons suffering from tuberculosis were more frequently found to have the worst of the socio-economic conditions for all the variables. Odds ratio (OR) increased by 3.14 (95% CI 2.48-3.98, p<0.001) for every decrease of Rs.500/- in the income level per person per month below Rs.2000/-. Similarly, the OR increased by 3.66 (CI 2.9-4.61,p<0.001) with increasing number of persons per room. The ORs for poorer housing, toilet facilities, water supply and consumer articles were also significant. In multivariate logistic regression analysis, the age, level of education, crowding, type of housing, water supply and number of consumer articles in the household was found to be independently and significantly associated with a higher risk of TB. Conclusion: There is a significant SES-health gradient in TB prevalence; tuberculosis risk increases with lowering of socio-economic status.
