Abstract

We have previously shown that type 2 diabetic patients have decreased plasma concentrations of glucagon-like peptide 1 (GLP-1) compared with healthy subjects after ingestion of a standard mixed meal. This decrease could be caused by differences in the metabolism of GLP-1. The objective of this study was to examine the pharmacokinetics of GLP-1 in healthy subjects and type 2 diabetic patients after iv bolus doses ranging from 2.5-25 nmol/subject. Bolus injections iv of 2.5, 5, 15, and 25 nmol of GLP-1 and a meal test were performed in six type 2 diabetic patients [age, mean (range): 56 (48-67) yr; body mass index: 31.2 (27.0-37.7) kg/m(2); fasting plasma glucose: 11.9 (8.3-14.3) mmol/liter; hemoglobin A(1C): 9.6 (7.0-12.5)%]. For comparison, six matched healthy subjects were examined. Peak plasma GLP-1 concentrations increased linearly with increasing doses of GLP-1 and were similar for type 2 diabetic patients and healthy subjects. The peak concentrations of total GLP-1 (C-terminal) after 2.5, 5, 15, and 25 nmol of GLP-1 were 357 +/- 56, 647 +/- 141, 1978 +/- 276, 3435 +/- 331 pmol/liter in the type 2 diabetic patients and 315 +/- 37, 676 +/- 64, 1848 +/- 146, 3168 +/- 358 pmol/liter, respectively, in the healthy subjects (not statistically significant). Peak concentrations of the intact GLP-1 peptide (N-terminal) were: 69 +/- 17, 156 +/- 44, 703 +/- 77, and 1070 +/- 117 pmol/liter in the type 2 diabetic patients and 75 +/- 14, 160 +/- 40, 664 +/- 79, 974 +/- 87 in the healthy subjects (not statistically significant). GLP-1 was eliminated rapidly with clearances of intact GLP-1 after 2.5, 5, 15, and 25 nmol of GLP-1 amounting to: 9.0 +/- 5.0, 8.1 +/- 6.0, 4.0 +/- 1.0, 4.0 +/- 1.0 liter/min in type 2 diabetic patients and 8.4 +/- 4.2, 7.6 +/- 4.5, 5.0 +/- 2.0, 5.0 +/- 1.0 liter/min in healthy subjects. The volume of distribution ranged from 9-26 liters per subject. No significant differences were found between healthy subjects and type 2 diabetic subjects. We conclude that elimination of GLP-1 is the same in obese type 2 diabetic patients and matched healthy subjects. The impaired incretin response seen after ingestion of a standard breakfast meal must therefore be caused by a decreased secretion of GLP-1 in type 2 diabetic patients.

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.
