Abstract
BACKGROUND: Patients with chronic hepatitis B virus (HBV) infection are at risk of developing liver disease. Serum hepatitis B core-related antigen (HBcrAg) is a new biomarker for intrahepatic templates for HBV replication. AIM: To explore whether a high HBcrAg level is associated with increased risk of cirrhosis, especially in patients with intermediate viral load (HBV DNA 2000-19 999 IU/mL) due to their moderate risk of disease progression. METHODS: A total of 1673 treatment-naïve, non-cirrhotic patients with negative hepatitis B e antigen (HBeAg) and alanine aminotransferase (ALT) level 20 000 IU/mL after 3 years of follow-up. CONCLUSIONS: In HBeAg-negative patients with normal ALT levels, higher HBcrAg levels are associated with increased risk of cirrhosis. Among those with intermediate viral load, HBcrAg <10 KU/mL defines a low-risk group for disease progression.
