To assess the impact of highly active antiretroviral therapy (HAART) on rates of change of antiretroviral treatment among patients co-infected with hepatitis B virus (HBV) and/or hepatitis C virus (HCV) in the Australian HIV Observational Database (AHOD).
Analysis was based on 805 of the 2218 patients recruited to the AHOD by March 2003, who had commenced HAART after 1 January 1997, who had recorded test results for HBV surface antigen and anti-HCV antibody, and who had follow-up of more than 3 months. The effect of hepatitis co-infection on the rate of antiretroviral treatment change after commencing HAART was assessed using a random-effect Poisson regression model.
Among those included in the analyses, the prevalences of HBV and HCV were 4.8% and 12.8%, respectively. The overall rate of combination antiretroviral treatment change was 0.74 combinations per year. Factors independently associated with an increased rate of change of combination antiretroviral treatment were: prior AIDS-defining illness; prior exposure to double combination antiretroviral therapy; and antiretroviral treatment class. Co-infection with HBV and/or HCV was not found to be significantly associated with the rate of combination antiretroviral treatment change.
While both HBV and HCV co-infections are relatively common in the AHOD, they do not appear to be serious impediments to the treatment of HIV-infected patients.
