ABSTRACT Objective:To systematically review the effects of Glucagon like peptide 1 receptor agonists (GLP-1 RAs) on headache and dizziness among type 2 diabetes (T2DM) patients. Methods:Medline, Embase, Clinical trials and Cochrane library were searched from inception through June 23, 2017 to identify randomized clinical trials (RCTs) assessing safety of GLP-1 RAs versus placebo or other anti diabetic drugs in T2DM. Network Meta analysis within a Bayesian framework was performed to calculate odds ratios for the incidence of headache and dizziness.Results:In the study, 100 RCTs were included, including 15 treatments: 8 GLP-1 RAs ( exenatide, exenatide long release agent, liraglutide, lixisenatide, taspoglutide, albiglutide, dulaglutide and semaglutide), placebo, 2 dipeptidyl peptidase 4 inhibitors (sitagliptin and vildagliptin) and 4 traditional anti diabetic drugs (insulin, metformin, sulfonylureas and thiazolidinediones ketones (TZD)). Compared with insulin, exenatide, liraglutide, lixisenatide and taspoglutide significantly increased the incidence of headache, with OR of 1.35 (95%CI: 1.13 1.60), 1.35(95%CI: 1.12 1.62), 1.59 (95%CI: 1.22 2.06) and 1.78(95%CI: 1.33 2.37), respectively. Significant lowering effects on dizziness were found when liraglutide and exenatide versus placebo, insulin, TZD (range of ORs: 1.56 2.56). The result from the network Meta analysis based on Bayesian theory could be used to rank all the treatments included, which showed that taspoglutide ranked third with maximum risk on headache, liraglutide ranked first with maximum risk on dizziness.Conclusion:Exenatide long release agent and taspoglutide were associated with significantly increasing effect on headache, liraglutide was associated with significantly increasing effect on dizziness. |
