Core Tip

Core tip: Autoimmune hepatitis (AIH) is a chronic liver disease of unknown etiology. In this in-depth review we summarize the substantial progress on etiopathogenesis, clinical, serological and histological phenotypes of AIH. AIH has a global distribution affecting any age, both sexes and all ethnic groups. Clinical manifestations vary from asymptomatic to severe hepatitis. Polyclononal hypergammaglobulinemia is characteristic in most cases, while histology and autoantibodies detection are still the hallmark for timely diagnosis. Laboratory personnel, hepato-pathologists and clinicians need to become more familiar with disease expressions and the interpretation of liver histology and autoimmune serology to derive maximum benefit for the patient.
