Autoimmune hepatitis (AIH) is an idiopathic inflammatory liver disease with genetic susceptibility and unknown environmental triggers. The gold standard for diagnosis, International Autoimmune Hepatitis Group (IAIHG) scoring system, classifies AIH as definite or probable. Conventional research on probable AIH has focused on the Caucasian population and there is little data pertaining to the Asian population. ⋯ Classification of probable or definite disease did not alter overall survival with statistical significance. In conclusion, our findings suggest that probable AIH should be managed as definite AIH is managed in Japanese population. The albumin-bilirubin score helps identify liver cirrhosis and is a prognostic biomarker for overall survival.
