Nevirapine-based antiretroviral therapy against human immunodeficiency virus (HIV) among Tuberculosis (TB) co-infected individual is complicated as administration of rifampicin along with Nevirapine reduces the plasma concentration of Nevirapine. The objective of the present study is to compare efficacy and safety of Nevirapine 400 mg once daily (OD) based antiretroviral therapy (ART) with efavirenz based ART and twice daily dose (200 mg) of Nevirapine-based ART regimens in HIV-TB co-infected individuals. ART-naïve HIV-TB patients were randomly assigned to receive either Nevirapine 400 mg OD with zidovudine and lamivudine (Group 1; n=30), Nevirapine 200 mg BD (Group 2; n=30), efavirenz 600 mg (Group 3, n=31); Nevirapine 400 mg OD with tenofovir (Group 4; n=30) and Nevirapine 400 mg OD without concomitant antitubercular therapy (ATT) (Group 5; n=30). The end points were virological (viral load), immunological (CD4 count) and clinical responses and progression of HIV disease marked by the failure of ART. Our results suggest that Nevirapine 400 mg OD based therapy is as effective as efavirenz-based ART in terms of clinical, immunological and virological response. Our data suggests that Nevirapine 400 mg OD group had favorable treatment outcome as compared to Nevirapine 200 mg 1 BD group.

We conclude that Nevirapine 400 mg OD based ART combined with tenofovir and lamivudine could be an effective alternative to improve compliance in the resource-limited settings in patients with HIV-TB co-infection. Further large multicentric study with bigger sample size will be required to confirm these findings.
