Aim: Drug-induced autoimmune hepatitis (DIAIH) remains poorly characterized. Our aim was to assess natural history and outcomes in DIAIH.\ud \ud Methods: This was a retrospective cohort study.\ud \ud Results: Eighty-two patients with autoimmune hepatitis (AIH) were identified, 11 (13.4%) with DIAIH, implicated drugs being nitrofurantoin (n = 4), statins (n = 4), herbal remedies (n = 2) and diclofenac (n = 1). Female sex, acute onset, elevated serum globulins/immunoglobulin G, fibrosis stage (Ishak), cirrhosis at onset, moderate–severe portal inflammation, interface and lobular hepatitis, remission, relapse and poor outcome were similar in those with DIAIH and AIH (P > 0.05). The former were however more likely to be aged 60 years or more and take longer to relapse on immunosuppression discontinuation (P = |
