Abstract

Aims/hypothesis Long-term trials in insulin-treated subjects with type 2 diabetes have shown that adjunctive treatment with the amylin analogue pramlintide reduces HbA(1)c levels and elicits weight loss. While amylin reduces food intake in rodents, pramlintide's effect on satiety and food intake in humans has not yet been assessed. Methods In this randomised, double-blind, placebo-controlled crossover study, 11 insulin-treated men with type 2 diabetes (age 60+/-9 years, BMI 28.9+/-4.8 kg/m(2)) and 15 non-diabetic obese men (age 41+/-21 years, BMI 34.4+/-4.5 kg/m(2)) underwent two standardised meal tests. After fasting overnight, subjects received single subcutaneous injections of either pramlintide (120 microg) or placebo, followed by a preload meal. After 1 h, subjects ate an ad libitum buffet meal. Energy intake and meal duration were measured, as were hunger ratings (using visual analogue scales), and plasma cholecystokinin, glucagon-like peptide-1 and peptide YY concentrations over time. Results Compared with placebo, pramlintide reduced energy intake in both the type 2 diabetes (Delta-202+/-64 kcal, -23+/-8%, p<0.01) and obese (Delta-170+/-68 kcal, -16+/-6%, p<0.02) groups, without affecting meal duration. Hunger and hormonal analyte profiles provided evidence that pramlintide may exert a primary satiogenic effect, independently of other anorexigenic gut peptides. Conclusions/interpretation The results indicate that enhanced satiety and reduced food intake may explain the weight loss observed in long-term pramlintide trials.

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.
