Background
Only a few randomized controlled trials (RCTs) and some uncontrolled trials have reported the efficacy and adverse events (AEs) of tacrolimus (Tac) in patients with refractory Crohn’s disease (CD). The aim of this study was to undertake a systematic review and meta-analysis of the therapeutic efficacy and AEs of Tac in patients with CD.
Methods
We investigated studies reporting the therapeutic efficacy of Tac in patients with CD from 1950 until December 2017. Study subjects were categorized into three groups: systemic administration of Tac for patients with luminal CD (Group 1); systemic administration of Tac for patients with perianal CD (Group 2); and topical administration of Tac for patients with localized CD (Group 3). The primary endpoint of this study was the remission rate. Secondary endpoints were partial response rate, factors related to remission, and the incidence of AEs.
Results
The remission rate of Group 1, 2, and 3 was 37.1, 32.0, and 22.7%, respectively. The partial response rate of those was 42.3, 42.9, and 44.3%, respectively. In addition, the incidence of AEs of those was 50.9, 65.5, and 40.0%, respectively. No life-threatening AEs were observed in any study.
Conclusion
This systematic review and meta-analysis demonstrated that Tac therapy was effective for subpopulation of CD patients and that the incidence of AEs was tolerable. Therefore, Tac therapy should be considered an option for patients with CD. However, there have been few well-designed RCTs on this subject and further studies are required.
