Autoimmune hepatitis preceded by hepatitis A
Autoimmune hepatitis is characterized by unresolving inflammation and fibrosis of the liver, which untreated may lead to cirrhosis. The pathogenesis remains unclear and reflects a complex interaction between autoantigens, genetic predisposition, triggering factors and immune regulation. In rare cases, acute hepatitis A has been suspected as a triggering factor. We describe a case of a 66-year-old woman who two months after a resolving acute hepatitis A presented with fatigue, pale stools and elevated levels of transaminases. A liver biopsy showed histological changes compatible with autoimmune hepatitis.
