| Popis: | The contribution of GLP-1 on glucose control after gastric bypass (GBP) is not fully elucidated. Hypotheses: The improvement in β-cell glucose sensitivity (BCGS) to oral glucose after GBP is GLP-1 mediated, weight loss independent, and varies according to diabetes (T2D) remission status; The administration of exendin 9-39 (EX9), a GLP-1 receptor blocker, has minimal effect on blood glucose. Methods: Patients with T2D (n=29) underwent a 75 g OGTT prior to and at 3, 12 and 24 months (M) after GBP. Glucose, insulin secretion rates (ISR), BCGS, and glucagon were measured with and without EX9. The cohort was retrospectively divided into 3 groups based on T2D remission status determined at the latest study time point (24 or 12M): remitters (REM, n=5), persistent T2D (P-T2D, n=8), impaired (IGT, n=16). Results: Prior to GBP, patients were 42.9±8.3y old, had a BMI of 42.4±4.6 kg/m2, 7.7±7.3 y known T2D duration, an HbA1c of 7.8±1.1% (35% on insulin) and an HOMA-IR of 11.5±5.8. Both magnitude and temporal increases in BCGS varied according to remission status: greater (up to 6.5 fold, p Conclusions: Our data suggest that the effect of endogenous GLP-1 on pancreatic endocrine function and glucose varies with time and according to remission status after GBP.
