[Effects of anti-diabetic therapy on overweight/obesity and dyslipidemia: traditional hypoglycemic agents (metformin, sulfonylureas, thiazolidinediones) versus glucagon-like peptide-1 analogs and dipeptidyl peptidase-4 inhibitors]

Abstract

Obesity and dyslipidemia often coexist in patients with type 2 diabetes and contribute to increase the risk of cardiovascular events. Pharmacological treatments of diabetes often result in weight gain, an undesirable event associated with a worse cardiovascular risk profile and decreased adherence to therapy. Dipeptidyl peptidase-4 (DPP-4) inhibitors and glucagon-like peptide-1 (GLP-1) analogs have been shown to improve glycemic control without promoting weight gain and to exert beneficial effects on lipid profile by reducing total and LDL cholesterol, triglycerides, and free fatty acid levels. DPP-4 inhibitors have demonstrated to be weight neutral whereas treatment with GLP-1 analogs is associated with a significant weight loss. DPP-4 and GLP-1 analogs represent a new therapeutic option for type 2 diabetes, which offers the advantage of combining glycemic control with beneficial effects on body weight and lipid profile, thus providing greater cardiovascular protection.
