Tuberculosis co-infection in HIV infected persons of Kathmandu.
Tuberculosis is itself a major Public health problem in Nepal and the emergence HIV further complicated the issue. A cross-sectional analytical study was conducted between January 2004 and August 2005, with a general objective to determine the Tuberculosis co-infection status in HIV/AIDS cases of Nepal. Altogether 100 HIV infected persons visiting different Voluntary counseling and testing centers (VCT) and HIV/AIDS care centers located in Kathmandu valley were enrolled in the study. Investigation of tuberculosis was done by standard method prescribed by WHO using sputum specimen. Among 100 HIV infected cases, 66 (66.0%) were males and 34 (34.0%) were females. Majority of the HIV cases were in the age group 21-30 (60.0%) followed by 31-40 (31.0%). Tuberculosis was detected in 23 cases with highest prevalence in the age group 21-30 years (65.2%). No significant relationship could be established between gender and TB (c2 = 0.83, p > 0.01).Significant relationship was established between smoking/alcoholic habit and the subsequent development of tuberculosis (c2 = 7.24, p < 0.05 for smoking habit; c2 = 4.39, p < 0.05 for alcoholic habit at 1 degree of freedom). Among 22 culture positive isolates the predominant was Mycobacterium avium complex (40.9%) followed by M. tuberculosis (27.3%), M. kansasii (18.2%), M. fortuitum (9.1%) and M. chelonae (4.5%). Among the 23 cases of tuberculosis, 22 cases were diagnosed by cultural technique of which 4 cases were smear positive while the remaining one case was diagnosed by direct microscopy although it was culture negative. Smear negative Tuberculosis is found to be alarmingly higher in HIV positive individuals of productive age group. The disease significantly higher in smokers and alcoholics.
