Background: Some children with chronic hepatitis B develop advanced liver disease. Lamivudine, an oral nucleoside, is a therapeutic option. A recent large, multicenter study demonstrated that lamivudine was superior to placebo in eliciting loss of hepatitis B e antigen (HBeAg) and hepatitis B virus (HBV) DNA from serum in children (2 to 17 years) treated for 52 weeks. Objective: To identify pretreatment factors that predict the likelihood of response to lamivudine in children with chronic hepatitis B infection. Study design: Data from the multicenter trial in 297 children (191 lamivudine, 96 placebo) were analyzed for the effects of baseline factors on the likelihood of responses. These responses included virologic response, defined as loss of HBeAg and HBV DNA, and HBeAg seroconversion, defined as loss of HBeAg and development of antibody to HBeAg. Univariate and multivariate analyses examined the effects of lamivudine treatment, age, gender, race, body weight, body mass index, previous interferon treatment and baseline alanine aminotransferase (ALT), histologic activity index (HAT) score and HBV DNA on the virologic responses. Results: In the univariate analysis higher baseline ALT, higher HAI score and lower HBV DNA level predicted a greater likelihood of virologic responses to lamivudine. In the multivariate model only baseline ALT and HAI score were predictive of responses. There was no effect of age or ethnicity on response. Conclusions: Children with higher pretreatment ALT and HAI scores are most likely to respond to lamivudine. Age, ethnicity and other factors do not significantly influence the frequency of virologic responses in children with chronic hepatitis B infection.
