Although alcohol abuse is the most common cause of liver cirrhosis in the United States, the enhancing effects of alcohol on the long-term prognosis of hepatitis C virus (HCV) related liver cirrhosis has not been clarified. To investigate how alcohol abuse influences the prognosis of hepatitis virus related liver cirrhosis, we studied 716 Japanese patients. Cumulative survival and hepatocellular carcinoma (HCC) development rates were analyzed in alcohol abusive, cirrhotic patients with or without hepatitis virus infection. Patients who abused alcohol were younger (p<0.0001) than HCV infected, non-abusive patients. The overall survival rate among patients with alcoholic cirrhosis (Al group), HCV related cirrhosis (HCV group), and HCV infected + alcoholic cirrhosis (HCV + Al group), showed no significant differences, although the 10-year cumulative survival rate of Al group was the highest of the three groups. The HCC development rate of Al group was the lowest. In addition, alcohol abuse decreased the survival rates of HCV group in the early stage with no HCC (p = 0.0028). In conclusion, alcohol abuse might affect the progression of liver damage in HCV infected patients with liver cirrhosis in the early stage, although the influence of alcohol abuse on the long term prognosis seems to be rather small.
