The effect of a dual combination of noninsulin antidiabetic drugs on lipids: a systematic review and network meta-analysis
Abstract
OBJECTIVE: As an ever widening array of anti-hyperglycemic agents are now available, the effect of these drugs on lipids is increasingly complex and controversial. The present meta-analysis was designed to clarify the effect of a dual combination of noninsulin anti-hyperglycemic agents on lipids in type 2 diabetes.
METHODS: Randomized controlled trials comparing different dual combinations of antidiabetic drugs were identified by searching PubMed, Cochrane Library, and Embase. Study selection, data abstraction and quality assessment were carried out by two reviewers independently. Change in low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglyceride and total cholesterol were pooled by both traditional meta-analysis and network meta-analysis.
RESULTS: Eighteen studies with a total of 10,222 patients were included. Network meta-analysis suggested that metformin + dipeptidyl peptidase-4 inhibitors (DPP-4) (LDL cholesterol: -0.19 mmol/L; HDL cholesterol: 0.06 mmol/L; triglycerides: -0.73 mmol/L; total cholesterol: -0.4 mmol/L) and metformin + glucagon-like peptide-1 (GLP-1) agonist (LDL cholesterol: -0.3 mmol/L; HDL cholesterol: 0.06 mmol/L; triglycerides: -0.64 mmol/L; total cholesterol: -0.5 mmol/L) were associated with relatively larger beneficial effects on the lipid profile among all combinations. Compared with metformin + thiazolidinedione, metformin + GLP-1 agonist (mean difference: -0.38; 95% confidence interval [CI]: -0.66 to -0.10) significantly…
