Background: Several years ago the International Autoimmune Hepatitis Group simplified the previous revised original scoring system for diagnosis of autoimmune hepatitis (AIH) into a scoring system based on only four instead of 13 parameters. Objective: We aimed to evaluate the suitability of the simplified AIH score for diagnosis of AIH in a German cohort with chronic liver diseases. Methods: In this retrospective single-center study, we compared the accuracy of both AIH scores in 70 patients with AIH and 211 patients with chronic liver diseases (PBC (n=52), PSC (n=27), NASH (n=67), DILI (n=15), CHB/C (n=50)). Sensitivity, specificity and predictability of each scoring system were calculated. Results: Using the simplified AIH score, the sensitivity and specificity of detecting a probable AIH (scores >= 6) were 96% and 97% with a positive and negative predictive value of 92% and 99%, respectively. For diagnosis of definite AIH (scores >= 7), the sensitivity and specificity were 43% and 100% with a positive and negative predictive value of 97% and 84%, respectively. The concordance with the revised original criteria was 63%. The specificity for excluding AIH was excellent in both scoring system. Conclusion: The simplified diagnostic criteria allow a reliable diagnosis of AIH in a German cohort.
