Abstract

Background:

There are limited treatment options for children with steroid-refractory or dependent ulcerative colitis (UC). A few observational studies suggest efficacy of oral tacrolimus. We performed a systematic review and meta-analysis to assess the efficacy of tacrolimus in pediatric UC.

Methods:

PubMed and Scopus were searched for publications related to the use of oral tacrolimus in pediatric UC. Data regarding the clinical response and colectomy-free survival were extracted from studies that met the selection criteria.

Results:

The search strategy yielded 492 articles of which 7 studies were included in the final review. They included 166 children (111 steroid-refractory, 52 steroid-dependent, 3 no steroids). Majority of cases (150/166 [90%]) were naïve to biologics. An initial response to tacrolimus therapy was seen in 84% (95% CI: 73%–93%) (n = 7 studies). No difference was observed between children with high (>10 ng/mL) or low tacrolimus levels (127/150 [85%] vs 12/16 [75%], P = 0.3). No difference in initial response between the children who were steroid refractory or dependent (92/111 [83%] vs 46/52 [88%], P = 0.36). The response in the biologic-exposed group (n = 10) was 70%. At 1-year follow-up, 15.2% (95% CI: 7%–21%) (n = 2 studies, 85 patients) had a sustained response on only tacrolimus. The pooled frequency of 1-year colectomy-free survival in children treated with initial oral tacrolimus was 64% (95% CI: 53%–75%). Twelve (7.2%) patients required cessation of therapy because of side effects.

Conclusion:

Tacrolimus has a high initial response in biologic naïve UC children. It can be effectively used as a bridge to other therapies with a 1-year colectomy-free survival of 64%.
