Background and aims: A limited number of drugs are used as standard or alternative therapies in autoimmune hepatitis (AIH). No specific-recommendations are available for patients failing to respond to these therapies. We analyzed the efficacy and safety of infliximab in patients with AIH. Approach and results: We performed a retrospective study of 42 patients with AIH who received infliximab at 21 liver centers in 12 countries. Patients were categorized according to the reason for infliximab therapy. Patients in group 1 (n=20) had failed standard, second-line (mycophenolate mofetil and 6-mercaptopurine) or third-line (tacrolimus or cyclosporine) therapy. In group 2 (n=22), infliximab was given for treatment of concomitant extrahepatic autoimmune diseases. Patients received a median of 17 (range: 3-104) infliximab infusions. Complete biochemical response (CR) was achieved or maintained in 33 (78%) patients during infliximab therapy. In group 1, infliximab induced CR in 11 of 20 (55%) patients. In group 2, 16 patients with CR prior to infliximab maintained remission, and the remaining six patients with active AIH (five on standard and one on both second and third-line therapy) showed CR following infliximab therapy. Infliximab led to CR in 75% (6/8) of non-responders to second-line and in 46% (6/13) of failing third-line therapy. Overall, 65% (17/26) of the patients with active AIH achieved CR on infliximab. Infliximab was discontinued in three patients of group 1. One patient had a severe allergic reaction and two developed anti-infliximab autoantibodies. Conclusion: Our study suggests that infliximab may be an effective and safe rescue therapy in AIH.
