Sera from 899 hepatitis B surface antigen (HBsAg) carriers from four separate ethnic groups (Caucasian, Australian Aboriginal, Melanesian, and Asian) were studied for their correlation for hepatitis B virus deoxyribonucleic acid (HBV DNA) and hepatitis B e antigen (HBeAg). Discordance, as signified by the absence of HBV DNA despite the presence of HBeAg, was unusual in Caucasians but frequently occurred in the other three ethnic groups (11–25%). Analysis by age showed that it occurred occasionally during childhood and, in this age group, may simply be part of the process of seroconversion with impending loss of HBeAg, whereas its greater prevalence in patients with liver disease may have a different mechanism. In sera obtained from Melanesians with hepatocellular carcinoma and Asians with chronic hepatitis, discordance was a common feature with HBV DNA being undetectable in those with HBeAg in 87% and 72%, respectively. A number of important implications flow from these observations pertinent to the use of HBeAg to detect replicating virus and the prognostic significance of HBeAg in HBsAg carriers when HBV DNA is undetectable.
