Background: Extrapulmonary tuberculosis is one of the major causes of exudative pleural effusion. The paucibacillary nature of effusion suggests the need of markers and methodologies for accurate diagnosis and prognosis of tuberculosis as well as to differentiate it from other non-tubercular causes of pleural effusion.Objectives: This study was focused to evaluate the utility of polymerase chain reaction (PCR) in detection of tuberculosis antigen and to assess the level of Adenosine Deaminase (ADA) in tubercular pleural effusion (TPE) and contrast it with other causes.Methods: This is a cross-sectional study where 100 samples of pleural effusion suspected to be tuberculosis were analyzed by PCR for the detection of IS6110 segment of DNA. The level of ADA was then determined and compared in both PCR positive and negative samples. The cut-off value of ADA was >40 U/L for TPE. Student t test was applied to compare the means with statistical significance set at p<0.05.Results: Out of 100 samples analyzed, 45% were positive for TPE and remaining 55% were non-tuberculosis pleural effusion as detected by PCR. The level of ADA was above cut-off (>40 U/L) in 43% TPE samples whereas all the non-tuberculosis effusion had ADA <40 U/L (p<0.001).Conclusion: The ADA level was significantly higher in TPE than in non-tuberculosis cases, and PCR was able to detect suspected cases of tuberculosis effusion in almost half of the cases. This finding suggests the diagnostic utility of combined use of ADA and PCR in diagnosis of TPE. J-GMC-N | Volume 11 | Issue 01 | January-June 2018, Page: 5-9

Introduction: The risk of active Tuberculosis increases after HIV seroconversion. It progressively increases with declining immunity. Tuberculosis (TB) epidemics in HIV has led to a dramatic upsurge in global TB incidence, resulting in remarkable increase in morbidity and mortality. Many clinical studies had shown that TB is one of the commonest opportunistic infection. This study is conducted to see the incidence of tuberculosis as an opportunistic infection in patients with HIV getting combined antiretroviral therapy (cART) Materials and Methods: This was a hospital based cross-sectional comparative study. Five hundred patients with HIV who are getting cART were enrolled in the study. Results: Analysis of individuals with HIV in our study amongst the 500 patients 266 (53.2%) were males and the remaining 234 (46.68%) were females. Amongst these HIV patients 48(18.04%) males and 17(7.26%) females had tuberculosis. 65(13%) of patients were TB/HIV co-infected. 2(4.1%) of these male TB/HIV patients had cervical gland TB. Conclusion: The incidence of tuberculosis in HIV infected individuals is high. TB is the commonest opportunistic infection (OIs) in people living with HIV/AIDS. Males are predominant gender to have TB/HIV co-infection.
