title: Risk of hepatitis A superinfection in patients with underlying liver disease.
abstract: During recent years the outcome of acute hepatitis A in chronic liver disease has been discussed controversially. Data from large hepatitis A epidemics and surveillance data from the United States suggest a significantly higher risk of fatal outcome in patients with chronic hepatitis B. Patients with chronic active hepatitis or liver cirrhosis seem to be at highest risk, while HBsAg carriers may exhibit a benign course of the disease. Patients with chronic hepatitis C also seem to have a significantly higher risk of fulminant hepatic failure when superinfected with hepatitis A. The recently reported unsuspected coincidence of autoimmune markers with a fulminant course of hepatitis A in those patients needs to be confirmed. Vaccination against hepatitis A in patients with chronic liver disease has been shown to be safe and effective.
