Hepatitis Bs antibody in alcoholic cirrhosis.

Sera from patients with chronic liver disease were tested for antibody against hepatitis B surface antigen by radioimmunoassay. The antibody was found in 25% of patients with alcoholic cirrhosis and in 52% when alcoholic cirrhosis was associated with portal hypertension, these results being significantly higher than in a matched control population. Other forms of chronic liver disease did not differ from the control population. Hepatitis B virus infection might be a factor in determining which alcoholic patients go on to develop chronic liver disease and cirrhosis.
