BACKGROUND & AIMS: Predniso(lo)ne with or without azathioprine is considered the mainstay in the treatment of autoimmune hepatitis (AIH), but many therapeutic options are available. The primary objective of this review was to explore the published literature on the optimal induction and subsequent maintenance therapy for AIH. METHODS: We performed a systematic search on electronic databases MEDLINE (1950-07.2009), Web of Science, Cochrane, and the website www.clinicaltrials.gov. Randomized controlled trials (RCTs) on apparent beneficial treatment regimens as induction or maintenance treatment in AIH were included. Pediatric studies were excluded. We calculated relative risks (RR) for comparison of treatment options on the primary outcome measure, which was defined as clinical, biochemical and histological remission. RESULTS: Eleven RCTs were included, of which 7 studies evaluated the induction therapy in AIH patients: 3 treatment naive (n=253), 2 relapse (n=53), 2 combination of naive and relapse (n=110). The remaining 4 studies (n=162) assessed maintenance therapy. All but one maintenance study (thymostimulin versus no therapy) studied predniso(lo)ne (PRED), azathioprine (AZA) or combination PRED+AZA. We found no differences in primary outcome between induction therapy with PRED and PRED+AZA in treatment naive patients (RR=0.98; 95% CI 0.65-1.47). AZA monotherapy as induction was considered as not viable because of a high mortality rate (30%). This was similar in AIH patients who relapsed: RR for PRED versus PRED+AZA for inducing remission was not different: 0.71 (95% CI 0.37-1.39). PRED+AZA maintained remission more often than PRED (RR=1.40; 95% CI 1.13-1.73). Also AZA maintained a higher remission rate than PRED (RR=1.35; 95% CI 1.07-1.70). Maintenance of remission was not different between PRED+AZA and AZA (RR=1.06; 95% CI 0.94-1.20). CONCLUSIONS: Based on available RCTs, PRED monotherapy and PRED+AZA combination therapy are both viable induction therapies for AIH treatment naives and relapsers, while for maintenance therapy PRED+AZA and AZA therapy are superior to PRED monotherapy.
