ABSTRACT
Hepatitis B virus e antigen (HBeAg) loss and the appearance of antibodies to HBeAg (anti-HBe) are favourable events in the history of chronic hepatitis B virus (CHB) infection. Most CHB patients have the HBeAg/anti-HBe profiles +/- or -/+, and little is published on the derivation or fate of the +/+ and -/- profiles. We have used electronically accessible patient data to study the HBeAg and anti-HBe profiles of a multi-ethnic cohort of adult HBV patients seen at a single centre over a period of more than 20 years. 3594 HBsAg-positive patients were identified and patients with viral coinfection or acute HBV infection were excluded. Cross-sectional and longitudinal analyses of HBeAg/anti-HBe status were undertaken. Compared with White or Black patients, Chinese and Asian patients are more likely to be HBeAg positive during child-bearing years. Patients with +/+ profile are likely to undergo HBeAg loss and seroconversion during relatively short follow-up. Chinese patients have a relatively increased rate of seroconversion. For HBeAg-positive patients, the risk of seroconversion diminishes with advancing age. Despite HBeAg loss, seroconversion is seldom observed after age 60 years. The proportion of HBV patients with -/- increases with age, and most acquire this profile by HBeAg loss but without antecedent seroconversion. -/- patients can lose HBsAg and develop anti-HBs. It was not possible to demonstrate a favourable impact of antiviral treatment on the rate of HBeAg seroconversion.
