Background: On-treatment decline of serum hepatitis B surface antigen (HBsAg) may reflect the immunomodulatory effect of pegylated interferon (PEG-IFN) for hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB). We compared HBsAg decline across HBV genotypes between combined responders (HBeAg loss and HBV DNA < 10,000 copies/ml at week 78), HBeAg responders (HBeAg loss with HBV DNA > 10,000 copies/ml) and non-responders.
