The long-term course of chronic hepatitis B

The aim of this study was to assess the long-term outcome in hepatitis B virus (HBV)-infected patients according to HBV, hepatitis C virus (HCV), and hepatitis D virus (HDV) replication, focusing on survival, liver failure, and hepatocellular carcinoma (HCC). A cohort of 302 hepatitis B surface antigen (HBsAg)-positive subjects (mean age, 34 +/- 15.3 years; male/female 214/88; 39 subjects under 14 years) with biopsy-proven chronic hepatitis (86 with cirrhosis) was prospectively assessed, with a median follow-up of 94 +/- 37.6 months. One hundred nine patients received interferon alfa (IFN). At baseline, 86 subjects (28.5%) were hepatitis B e antigen (HBeAg)-positive (wild-type HBV), 80 (26.5%) were HBeAg-negative, HBV-DNA-positive, 76 (25.2%) had HDV infection, 43 (14.2%) had dual HBV/HCV infection, and 17 (5.6%) were negative for HBV-DNA, anti-HCV, and anti-HDV. During follow-up, decompensation of disease occurred in 46 subjects: 8 developed HCC, 36 developed ascites, and 2 developed jaundice. Five patients underwent transplantation. Thirty-five subjects died: 33 of hepatic and 2 of nonhepatic causes. Overall mortality was 5.2-fold that of the general population (95% CI: 3.6-7.3; 35 deaths observed, 6.7 expected; P
