Autoimmune hepatitis (AIH) is a chronic liver disease, which is characterized by the increase of immunoglobulin G (IgG) level, the presence of auto-antibodies and a typical histology, in the absence of other liver disease. Due to the heterogeneity of AIH manifestations, different scoring systems have been validated in order to make a reliable diagnosis. The two most recent scoring systems are: the revised International Autoimmune Hepatitis Group (IAIHG) criteria and the IAIHG simplified criteria. The second one is recommended by the European Association for the Study of the Liver (EASL) clinical practice guidelines (CPGs). The EASL clinical practice guidelines suggests that the treatment of ASAIH (Acute Severe AIH) is high doses of corticosteroids (superior to 1mg/kg/day) as early as possible and a lack of improvement within seven days should lead to listing for emergency liver transplantation (LT). However, the "lack of improvement" is not objectively defined and the grading of recommendation is III (Opinions of respected authorities). The hypothesis of the study is that the previously developed decisional score on a retrospective series will prospectively allow the differentiation between patients with ASAIH (Acute Severe AIH) who respond to corticosteroid therapy and should be maintained on treatment and patients who do not respond and should be rapidly evaluated for LT. The score will be computed at day 3 since corticosteroid introduction.

Prospectively validate the previously elaborated SURFASA-score, evaluating its ability to predict non-response outcome to corticosteroid therapy in a new population of patients with acute severe autoimmune hepatitis.
