Abstract

Chronic hepatitis B virus (HBV) infection can cause chronic hepatitis, cirrhosis, liver failure, and hepatocellular carcinoma (HCC). Chronic hepatitis B is characterized by an early replicative phase with hepatitis B e antigen (HBeAg) positivity, high serum HBV-DNA levels and disease activity (HBeAgpositive chronic hepatitis), and a late inactive phase with anti-HBe seroconversion, low or undetectable serum HBV-DNA, and liver disease remission (inactive carrier state). Another form is characterized by active disease due to HBV variants not expressing HBeAg (HBeAg-negative chronic hepatitis). Both types of chronic hepatitis B can lead to cirrhosis and its complications. The incidence of cirrhosis is two to five per 100 person-years, but may be as high as eight to 10 in HBeAg-negative cases. The incidence of HCC varies geographically and increases with the duration and severity of liver disease (0.1 to 8 per 100 person-years). The prognosis is reasonably good in compensated cirrhosis, but very poor following decompensation. Viral and environmental factors influence the natural history of chronic hepatitis B and explain the heterogeneity of its clinical outcomes.
