High discontinuation rate of azathioprine in autoimmune hepatitis, independent of time of treatment initiation.

Background: Guidelines regarding treatment for autoimmune hepatitis (AIH) favour two strategies for azathioprine (AZA) introduction: concurrent with steroids at induction or delayed by 2-4 weeks. The safety and efficacy of both strategies have been unexplored.

Methods: We established a cohort of 900 AIH patients from 12 centres in 7 European countries.

Rapid Response to Treatment of Autoimmune Hepatitis Associated With Remission at 6 and 12 Months.

Background & Aims: Changes in serum levels of transaminases immediately after initiation of treatment for autoimmune hepatitis (AIH) might be associated with biochemical markers of remission and liver-related events. We assessed the outcomes of patients with vs without rapid response to treatment of AIH in a large international cohort.

Methods: We performed a retrospective cohort study, collecting data from 2 independent cohorts of adults with AIH from 12 centers in 7 countries in Europe.
