Deep cholestatic jaundice as the predominant manifestation in autoimmune hepatitis.

Autoimmune hepatitis is a chronic liver disease of unknown etiology. The diagnosis is based on the exclusion of other liver diseases such as drug-induced liver disease, alcohol liver disease, viral liver diseases and so on, characterizing by elevation of transaminases, hypergammaglobulinemia, auto antibodies and the histological features of interface hepatitis and plasma cells infiltration. However, deep cholestatic jaundice as the initial presentation, with elevated serum transaminases one month later, is rare in autoimmune hepatitis. We described a case of type 1 autoimmune hepatitis with deep cholestatic jaundice and hyperbilirubinemia as the initial predominant manifestation. It demonstrated that the cholestasis can also occur as the initial predominant syndrome in autoimmune hepatitis and respond well to the treatment with the glycyrrhizin and ursodeoxycholic acid.
