The therapeutic goal of anti-HBV therapy in patients who are HBeAg-positive is to achieve long-term suppression of viral replication with undetectable HBV DNA, HBe seroconversion and loss of HBeAg.

WebHepatitis B e antigen (HBeAg) is a small polypeptide that exists in a free form in the serum of individuals during the early phase of hepatitis B infection, soon after HB surface antigen (HBsAg) becomes detectable. Serum levels of both HBeAg and HBsAg rise rapidly … HBeAg is a hepatitis B viral protein, produced by the HBcAg reading frame. It is an indicator of active viral replication; this means the person infected with Hepatitis B can likely transmit the virus on to another person (i.e. the person is infectious).
