摘要
Giant cell hepatitis(GCH)with autoimmune hemolytic anemia is a rare entity,limited to young children,with an unknown pathogenesis.We report the case of 9-mo old who presented with fever,diarrhea and jaundice four days before hospitalization.Physical examination found pallor,jaundice and hepatosplenomegaly.The laboratory workup showed serum total bilirubin at 101 μmol/L,conjugated bilirubin at 84 μmol/L,hemolytic anemia,thrombocytopenia and immunoglobulin G(IgG)and anti-C3d positive direct Coombs' test.The antinuclear,anti-smooth muscle and liver kidney microsomes 1 non-organ specific autoantibodies,antiendomisium antibodies were negative.Serological assays for viral hepatitis B and C,cytomegalovirus,herpes simplex and Epstein Barr virus were negative.The association of acute liver failure,Evan's syndrome,positive direct Coomb's test of mixed type(IgG and C3)and the absence of organ and non-organ specific autoantibodies suggested the diagnosis of GCH.The diagnosis was confirmed by a needle liver biopsy.The patient was treated by corticosteroids,immunomodulatory therapy and azathioprine but died with septicemia.
