Abstract:
OBJECTIVE:To evaluate the improvement effects of sitagliptin on islet B-cell function in type 2 diabetic patients systematically,and to provide evidenced-based reference. METHODS:Retrieved from PubMed,Cochrane library,EMBase, CJFD,Wanfang database,VIP and CBM,RCTs about sitagliptin alone or combined with routine plan(trial group)vs. placbo alone or combined with routine plan(control group)in the treatment of type 2 diabetes were collected. Two reviewers independent-ly screened studies according to exclusion and inclusion criteria,extracted data,and assessed the methodological quality according to Cochrane Manual 5.1.0. Meta-analysis was performed by using RevMan 5.3 software. RESULTS:A total of 5 RCTs were includ-ed,involving 1253 patients. The result of Meta-analysis showed that changes of islet B cell function index(Homa-B)[sitagliptin alone group:MD=9.21,95%CI(4.16,14.25),P<0.001;drug combination group:MD=7.24,95%CI(0.80,13.68),P=0.03] and changes of insulin resistance index(Homa-IR)[sitagliptin alone group:MD=-0.40,95%CI(-0.44,-0.36),P<0.001;drug combination group:MD=-0.35,95%CI(-0.63,-0.07),P=0.02] of trial group were significantly better than those of control group,with statistical significance. CONCLUSIONS:Sitagliptin shows certain therapeutic efficacy in improving islet B cell func-tion and insulin resistance.
