A case of hepatitis A and E coinfection in an autoimmune hepatitis patient / 대한내과학회지

ABSTRACT

In Korea, the number of Hepatitis A virus (HAV) infections has suddenly increased and has become the most common cause of acute viral hepatitis during recent years. A 36-year-old female was diagnosed with acute fulminant hepatitis caused by HAV. Her clinical symptoms and AST/ALT recovered after supportive treatment; however, a re-elevation of AST/ALT was observed. Weperformed another viral marker study, autoimmune marker study and liver biopsy to rule out another hepatic insult. As a result, anti- HEV IgM, an anti-nuclear antibody and anti-smooth muscle antibody were positive and liver histology showed chronic hepatitis. In conclusion, we report a case of hepatitis A and E coinfection in an autoimmune hepatitis patient.
