Background & objectives: Tuberculous pleuritis is used as a model to understand the protective immune response in tuberculosis. It is predominated by Th1 response at the site of infection, where a possible role for the leptin, a known enhancer of Th1 response, could be speculated. Hence, we investigated leptin levels in pleural effusions in patients with both tuberculous (TP) and non-tuberculous (NTP) pleural effusion. Methods: Leptin and cytokine levels were assessed in serum and pleural fluid of TP and NTP patients (N = 20 each) by ELISA. Multivariate regression analysis were performed to find the possible determinants of leptin taking leptin as the dependent and body mass index (BMI), gender, source of leptin [i.e., serum or pleural fluid (PF)], age and disease status as independent variables. Results: PF leptin levels were significantly higher than serum leptin levels in both the groups however the PF leptin levels were significantly lower in TP subjects compared to NTP. The results showed that the leptin was found to be dependent on BMI but not on the other parameters. However, regression analysis based on the source of leptin showed males to be a better predictor of leptin. No correlation was observed between leptin and measured immune parameters. Interpretation & conclusions: Our findings demonstrated that the decreased leptin levels were associated with reduction in BMI but not with the disease status in tuberculous pleuritis.
