HIV status among presumptive tuberculosis cases attending tertiary care centre in South India: HIV status among presumptive tuberculosis cases

Abstract

Introduction: In India, to increase human immunodeficiency virus (HIV) case detection, the National Technical Working Group on TB /HIV had made it mandatory to screen for HIV infection among presumptive tuberculosis (TB) cases. Material and methods: Our study was a cross-sectional study, conducted between June 2015 and December 2016 in a tertiary care institute (JIPMER), in South India, to estimate the prevalence of HIV among presumptive TB cases. Results: Among the 964 presumptive TB cases who attended pulmonary medicine OPD, 189 patients were sputum acid-fast bacilli (AFB) positive. Among the 189 sputum positive cases, 9 were HIV positive. Of the 964 presumptive TB cases, 879 gave consent for HIV testing and 33 (3.7%) turned out to be HIV positive. If only sputum positive cases had been screened for HIV, we would have missed 24 new HIV positive cases. The number needed to screen was 27 among presumptive TB cases and 18 among TB patients. Conclusions: The uptake of HIV testing (91%) and the diagnostic yield of 3.7% of HIV positive cases among the presumptive TB patients is quite high compared to that of the Revised National Tuberculosis Control Programme (RNTCP) mechanism of Puducherry. This reinforces the need to screen all the presumptive cases for HIV infection, to increase HIV case detection so that anti-retroviral therapy (ART) can be initiated early.
