Prevalence of markers of hepatitis viruses in out-patient alcoholics.

The prevalence of HCV, HBV and HAV markers was investigated in unselected patients attending an outpatient alcoholic clinic. Anti-HCV were detected in 35 (24%) of 144 patients studied, and at least one marker of HBV infection was present in 72 (50%). These results are significantly higher than in a matched control population. The presence of anti-HCV was related to previous blood transfusions and familial history of alcoholism. We conclude that alcoholics should be considered a high risk group for both HCV and HBV infection.
