Abstract

Context: The actions of both endogenous incretin hormones during a meal have not previously been characterized. Objective: Using specific receptor antagonists, we investigated the individual and combined contributions of endogenous glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide 1 (GLP-1) to postprandial glucose metabolism, energy expenditure, and gallbladder motility. Design: Randomized, double-blinded, placebo-controlled, crossover design. Setting: On four separate days, four liquid mixed meal tests (1894 kJ) over 270 minutes (min). Patients or Other Participants: Twelve healthy male volunteers. Interventions: Infusions of the GIP receptor antagonist GIP(3–30)NH2 (800 pmol/kg/min), the GLP-1 receptor antagonist exendin(9–39)NH2 (0–20 min: 1000 pmol/kg/min; 20–270 min: 450 pmol/kg/min), GIP(3–30)NH2+exendin(9–39)NH2, or placebo/saline. Main Outcome Measure: Baseline-subtracted area under the curve (bsAUC) of C-peptide. Results: Infusion of GIP(3–30)NH2+exendin(9–39)NH2 significantly increased plasma glucose excursions (bsAUC: 261 ± 142 mmol/L × min) during the liquid mixed meals compared with GIP(3–30)NH2 (180 ± 141 mmol/L × min; P = 0.048), exendin(9–39)NH2 (171 ± 114 mmol/L × min; P = 0.046), and placebo (116 ± 154 mmol/L × min; P = 0.015). Correspondingly, C-peptide:glucose ratios during GIP(3–30)NH2+exendin(9–39)NH2 infusion were significantly lower than during GIP(3–30)NH2 (P = 0.0057), exendin(9–39)NH2 (P = 0.0038), and placebo infusion (P = 0.014). GIP(3–30)NH2 resulted in significantly lower AUCs for glucagon than exendin(9–39)NH2 (P = 0.0417). Gallbladder ejection fraction was higher during GIP(3–30)NH2 compared with placebo (P = 0.004). For all interventions, energy expenditure and respiratory quotient were similar. Conclusions: Endogenous GIP and GLP-1 lower postprandial plasma glucose excursions and stimulate insulin secretion but only endogenous GIP affects gallbladder motility. The two incretin hormones potentiate each other’s effects in the control of postprandial glycemia in healthy men.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
