Obtaining a better understanding of the mechanisms associated with hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) loss in patients with hepatitis B virus (HBV) is important for treating pa-tients with chronic hepatitis B. We herein describe the case of a patient with HBV and human immunodefi-ciency virus whose chronic hepatitis was stabilized due to HBe and HBs seroconversion with the emergence of lamivudine-associated and core mutations after CD4 elevation. A full-length HBV DNA analysis indicated that HBsAg had been lost after the development of the rtS143T mutation, which corresponded to the emer-gence of the sF134L and core mutations. The details of this case shed some light on the mechanisms associ-ated with HBsAg and HBeAg clearance.
