title: Acute liver failure caused by concurrent autoimmune hepatitis and hepatitis B in a 16-year old girl.
abstract: A 16 year-old girl was admitted to hospital because of fatigue and somnolence, nausea, epistaxis and jaundice. Physical examination revealed jaundice, an enlarged liver and tenderness of upper right abdomen. Laboratory tests revealed an increased level of acute liver failure, bilirubin, bile acids, GGTP and a decreased prothrombin ratio, with elevated gamma-globulin and IgG levels, and the presence of anti-mitochondrial M2 antibodies and HBV infection markers. The patient was diagnosed with liver failure resulting from chronic hepatitis B with an autoimmune component. The treatment consisted of steroids, azathioprine, vitamin K, low-protein diet and lactulose enemas. After undergoing a molecular test (HBV DNA 3.23 × 10(5) IU/mL and mutations I 204 and I 80), the treatment was modified by adding entecavir. After one month the patient was discharged in good clinical condition, with the recommendation of continued entecavir, prednisone and azathioprine. In subsequent months, no clinical deterioration or abnormal biochemical liver function test results were found, despite the discontinuation of immunosuppressive therapy after 10 mo. The patient continues entecavir therapy.
