Efficacy and Safety of Concomitant Use of Nevirapine and Rifampicin With HIV-TB ("NVP")
The purpose of the study is to evaluate the efficacy and safety of Nevarapine and Rifampicin vs Efavirenz and Rifampicin in antiretroviral naive patients co-infected with HIV and TB and to investigate whether Rifampicin co-administration in clinical practice leads to a clinically relevant decrease of Nevirapine plasma concentrations in Indian patients co-infected with HIV and Tuberculosis and to characterize drug-associated toxicities (especially hepatic).

- Virological suppression at 48 weeks. [ Time Frame: 5 years ] [ Designated as safety issue: Yes ]
All patients underwent a detailed physical examination. Their body weight and height will be measured and their body mass index (BMI) was calculated. Haemoglobin, complete blood counts, erythrocyte sedimentation rate, fasting blood glucose, renal function tests, liver function tests, serum albumin, serum uric acid and routine urinalysis will be done for all patients.
Patients will be assessed at day 14 after the start of ART, then at day 28, 42 and every 4 weeks thereafter through 48 weeks. A complete haemogram, liver and kidney function tests will be obtained at all these visits. CD4 counts will be measured at 8 weeks, 24 weeks and 48 weeks after the start of ART. HIV plasma viral load will be measured at baseline, at 24 weeks and at the end of 48 weeks only in the cases. Trough nevirapine concentrations were assessed at day 14, day 28, day 42 and day 180, 12 hours after the evening dose of nevirapine.
- Number of Participants with Adverse Events especially Hepatotoxicity as a measure of Safety. [ Time Frame: 5 years ] [ Designated as safety issue: Yes ]Drug associated toxicities specially hepatitis were assessed in the subjects by performing liver function tests every 4 weeks during follow-up.
