Abstract

Insulin-resistant subjects have a slow onset of insulin action, and the underlying mechanism has not been determined. To evaluate whether a delayed transcapillary transport is part of the peripheral insulin resistance, we followed the kinetics of infused insulin and inulin in plasma and muscle interstitial fluid in obese insulin-resistant patients and control subjects. A total of 10 lean and 10 obese men (BMI 24 ± 0.8 vs. 32 ± 0.8 kg/m2, P < 0.001) was evaluated during a hyperinsulinemic-euglycemic clamp (insulin infusion rate 120 mU · m−2 · min−1) combined with an inulin infusion. Measurements of insulin and inulin in plasma were taken by means of arterial-venous catheterization of the forearm and microdialysis in brachioradialis muscle combined with forearm blood flow measurements with vein occlusion pletysmography. The obese subjects had a significantly lower steady-state glucose infusion rate and, moreover, demonstrated a delayed appearance of insulin (time to achieve half-maximal concentration [T1/2] 72 ± 6 vs. 46 ± 6 min in control subjects, P < 0.05) as well as inulin (T1/2 83 ± 3 vs. 53 ± 7 min, P < 0.01) in the interstitial fluid. Also, the obese subjects had a delayed onset of insulin action (T1/2 70 ± 9 vs. 45 ± 5 min in control subjects, P < 0.05), and their forearm blood flow rate was significantly lower. These results demonstrate a delayed transcapillary transport of insulin and inulin from plasma to the muscle interstitial fluid and a delayed onset of insulin action in insulin-resistant obese subjects.

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.
