Dual efficacy of lamivudine treatment in human immunodeficiency virus/hepatitis B virus-coinfected persons in a randomized, controlled study (CAESAR). The CAESAR Coordinating Committee.

The efficacy and safety of lamivudine in persons coinfected with human immunodeficiency virus (HIV) type 1 and hepatitis B virus (HBV) were examined in the CAESAR study, a randomized placebo-controlled trial assessing the addition of lamivudine (150 mg 2x/day) or lamivudine (150 mg 2x/day) plus loviride (100 mg 3x/day) to zidovudine-containing background antiretroviral treatment. Baseline hepatitis B surface antigen (HBsAg) results were available for 1790 study subjects, of whom 122 (6.8%) tested positive. Retrospective analyses for serial HBV DNA, HBsAg, and hepatitis B e antigen (HBeAg) were performed on stored sera from 118 HBsAg-positive subjects. HBV DNA and HBeAg were present in 83% and 63%, respectively. At weeks 12 and 52, median log10 HBV DNA change was -2.0 and -2.7, respectively, in the lamivudine arms, compared with no reduction among placebo recipients (P<.001). A trend to lower alanine transferase level, and delayed progression of HIV-1 disease (relative hazard, 0.26; 95% confidence interval, 0.08-0.80) were also seen in the lamivudine arms, compared with the placebo group.
