Overlap syndrome triggered by acute viral hepatitis A.

We report the case of a 24-year-old woman with an autoimmune hepatitis/primary biliary cirrhosis overlap syndrome triggered by an acute hepatitis A. A number of viruses have been proposed as potential triggers of autoimmune hepatitis in patients with genetic predisposition. To date, approximately 10 cases of type 1 autoimmune hepatitis following hepatitis A virus infection have been published in the medical literature. To our knowledge, this is the first case of overlap syndrome triggered by an acute hepatitis A.
