This study was designed to evaluate whether a proteinpreload could improve the efficacy of the dipeptidyl peptidase-4 (DPP-4)inhibitor vildagliptin to increase incretin concentrations, slow gastric emptying,and lower postprandial glycemia in type 2 diabetes.RESEARCH DESIGN AND METHODSTwenty-two patients with type 2 diabetes treated with metformin were studiedon four occasions, receiving either 50 mg vildagliptin (VILD) or placebo (PLBO) onboth the evening before and the morning of each study day.

Plasma glucose and hormones, and gastric emptying, wereevaluated.RESULTSCompared with PLBO/CTRL, PLBO/WHEY reduced postprandial peak glycemia,increased plasma insulin, glucagon, and incretin hormones (total and intact),and slowed gastric emptying, whereas VILD/CTRL reduced both the peak and areaunder the curve for glucose, increased plasma intact incretins, and slowed gastricemptying but suppressed plasma glucagon and total incretins (P < 0.05 each).Compared with both PLBO/WHEY and VILD/CTRL, VILD/WHEY was associatedwith higher plasma intact GLP-1 and GIP, slower gastric emptying, and lowerpostprandial glycemia (P < 0.05 each).CONCLUSIONSIn metformin-treated type 2 diabetes, a protein preload has the capacity to enhancethe efficacy of vildagliptin to slow gastric emptying, increase plasma intactincretins, and reduce postprandial glycemia.",
