Association between dipeptidyl peptidase-4 inhibitors use and leptin in type 2 diabetes mellitus

Background Dipeptidyl peptidase-4 inhibitors (DPP-4i) provide a unique antihyperglycemic effect by regulating incretin peptides in type 2 diabetes mellitus (T2DM) patients who are inadequately controlled with insulin therapy.
