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.
