Abstract

Background: HIV-TB (tuberculosis) coinfection has emerged as a major public health threat. Given the multifactorial enabling environment in a resource-constrained setting like India, the consequences are of epidemic proportions. Aims: This study was aimed at identifying the clinical and epidemiological determinants underlying HIV-TB coinfection. Settings and Design: A retrospective review of patient records was done from the antiretroviral therapy center (ART) center at a district hospital in southern India between May and August 2012. Materials and Methods: Secondary data of 684 patients on ART as well as pre-ART were collected between July 2008 and June 2012 and were analyzed. Statistical Analysis: Descriptive analysis, χ2 , and Wilcoxon signed rank tests were used with SPSS version 15.0 to draw significant statistical inferences. Results: HIV-TB coinfection was diagnosed in 18.9% with higher prevalence among males (75.3%), in the sexually active age group 31-45 years (61.3%), with less than primary education (44.15%), who were married (56.1%), laborers (42.4%), from rural backgrounds (88.2%), and having low income-earning capacity (94.4%). Transmission was predominantly through the heterosexual route. The key entry point was the integrated counseling and testing center (ICTC) (47.4%). Pulmonary tuberculosis (58.8%) was predominantly found followed by extrapulmonary tuberculosis (38.2%) and both in 3.1%. A favorable outcome was observed in 69.3% of coinfected patients with 89.2% on ART and 97.2% currently on DOTS therapy. The Wilcoxon signed-rank test found significant association between rises in CD4 counts after the 6 th -month follow up (P < 0.05). Coinfected patients had a case fatality rate of 25%. Conclusions: The prevalence of HIV-TB coinfection recorded in this sample was 18.86%. ICTC implemented by NACO emerged as an effective entry point, while Revised National Tuberculosis Control Program referred 1.6% (n = 11) of the patients to the ART center. Coinfection is associated with lower CD4 counts than those with HIV alone, which could translate into increased morbidity and progression of HIV to AIDS.
