Core tip: The mechanisms by which alcohol enhances disease progression are less well understood in chronic hepatitis B than in chronic hepatitis C. The association of light-to-moderate alcohol consumption with clinical outcomes in patients with chronic hepatitis B virus (HBV) infection appears modest. Although the threshold amount of alcohol for increasing hepatocellular carcinoma (HCC) risk remains unknown, heavy alcohol consumption significantly accelerates the progression of liver disease to cirrhosis and, ultimately, HCC. Alcohol abuse could impair the response to interferon-α therapy in chronic hepatitis B patients, although not fully confirmed, and can increase the risk of HCC even in patients with low HBV DNA levels during nucleoside/nucleotide therapy.
