Title
Standard-dose efavirenz vs. standard-dose nevirapine in antiretroviral regimens among HIV-1 and tuberculosis co-infected patients who received rifampicin
Abstract
Background: There is limited comparative data between efavirenz (EFV) 600mg/day and nevirapine (NVP) 400mg/day-based antiretroviral therapy (ART) among HIV-1 patients with tuberculosis (TB) and receiving rifampicin. Methods: A retrospective cohort study was conducted in all ART-naïve patients who were receiving rifampicin between January 2002 and December 2005. Results: Of 188 patients, 77 and 111 patients were initiated on EFV-based ART (EFV group) and NVP-based ART (NVP group), respectively. Overall, median [interquartile range (IQR)] CD4 count was 36 (15-77) cells/μL and median (IQR) viral load was 5.6 (5.2-5.9) HIV-1 RNA log copies/mL. At 48 weeks, 77.9% (60/77) in the EFV group and 67.6% (75/111) in the NVP group achieved HIV-1 RNA <50 copies/mL (P = 0.140, odds ratio = 0.590, 95% confidence interval = 0.302-1.153). At 24 and 48 weeks, respective median CD4 counts were 174 and 254 cells/μL in the EFV group and 156 and 218 cells/μL in the NVP group (P >0.05). By binary logistic regression, treatment group was not associated with HIV-1 RNA <50 copies/mL (P >0.05). No patient in the EFV group and eight (7.2%) patients in the NVP group discontinued ART because of adverse reactions (P = 0.084). Conclusions: For HIV-TB co-infected patients who receive rifampicin, efficacy of 600mg EFV-based and 400mg NVP-based ART may be similar, although adverse events tend to be higher in NVP-based ART. © 2008 British HIV Association.
