Abstract

AIM: To evaluate the efficacy and safety of integrin antagonists, including natalizumab and vedolizumab, in Crohn’s disease (CD).

METHODS: We carried out a literature search in PubMed, MEDLINE, EMBASE and the Cochrane Library to screen for citations from January 1990 to August 2014. Data analysis was performed using Review Manager version 5.2.

RESULTS: A total of 1340 patients from five studies were involved in this meta-analysis. During 6-12 wk treatment, integrin antagonists increased the rate of clinical response and remission with OR = 1.69, 95%CI: 1.37-2.09 and 1.84, 95%CI: 1.44-2.34, respectively. No significant difference was found between integrin antagonists and placebo treatments regarding their adverse reactions (OR = 1.07, 95%CI: 0.83-1.38) and serious adverse reactions (OR = 0.81, 95%CI: 0.57-1.15).

CONCLUSION: The results prove the efficacy and safety of integrin antagonists for CD treatment, although the treatment strategies varied.

Core tip: Integrin antagonists were used to treat Crohn’s disease (CD), but their efficacy and safety are not yet certain. We performed this systematic review and meta-analysis to evaluate the efficacy and safety of integrin antagonists, including natalizumab and vedolizumab, in CD. During 6-12 wk treatment, integrin antagonists increased the rate of clinical response and remission. There was no significant difference between integrin antagonists and placebo regarding their adverse reactions and serious adverse reactions. These results prove the efficacy and safety of integrin antagonists for CD treatment.
