Abstract

Neurotensin is a peptide with effects on appetite and intestinal lipid absorption. Experimental data suggest a role in glucose homeostasis, while human data is missing. Here, 20 morbidly obese subjects either underwent biliopancreatic diversion with duodenal switch (BPD), or Roux-en-Y gastric bypass (RYGB) in a randomized fashion. Before and 1 year after surgery, anthropometric data, body composition, clinical biochemistry, insulin sensitivity by means of euglycemic hyperinsulinemic clamps (HEC) and fasting plasma proneurotensin 1-117 were analyzed. Plasma proneurotensin increased significantly more 1 year after BDP than RYGB (P = 0.028), while weight loss was comparable. After metabolic surgery, proneurotensin correlated positively with insulin sensitivity (M-value) (r = 0.55, P < 0.001), while an inverse relationship with fasting glucose, HOMA-IR and HbA1c was observed (P < 0.05 for all components). After adjustment for age and gender, proneurotensin and BMI remained independently related with delta of M-value (β = 0.46 and β = 0.51, P < 0.05, resp.). From these data we conclude that proneurotensin positively correlates with insulin sensitivity uniquely after weight loss induced by metabolic surgery in humans. BDP leads to a stronger increase in the anorexigenic peptide compared to RYGB.

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.
