Abstract

It was the aim of this study to determine whether FFA inhibit insulin-stimulated whole body glucose uptake and utilization in patients with non-insulin-dependent diabetes. We performed five types of isoglycemic (approximately 11mM) clamps: (a) with insulin; (b) with insulin plus fat/heparin; (c) with insulin plus glycerol; (d) with saline; (e) with saline plus fat/heparin and two types of euglycemic (approximately 5mM) clamps: (a) with insulin; (b) with insulin plus fat/heparin. During these studies, we determined rates of glucose uptake, glycolysis (both with 3[3H] glucose), glycogen synthesis (determined as glucose uptake minus glycolysis), carbohydrate oxidation (by indirect calorimetry) and nonoxidative glycolysis (determined as glycolysis minus carbohydrate oxidation). Fat/heparin infusion did not affect basal glucose uptake, but inhibited total stimulated (insulin stimulated plus basal) glucose uptake by 40-50% in isoglycemic and in euglycemic patients at plasma FFA concentration of approximately 950 and approximately 550 microM, respectively. In isoglycemic patients, the 40-50% inhibition of total stimulated glucose uptake was due to near complete inhibition of the insulin-stimulated part of glucose uptake. Proportional inhibition of glucose uptake, glycogen synthesis, and glycolysis suggested a major FFA-mediated defect involving glucose transport and/or phosphorylation. In summary, fat produced proportional inhibitions of insulin-stimulated glucose uptake and of intracellular glucose utilization. We conclude, that physiologically elevated levels of FFa could potentially be responsible for a large part of the peripheral insulin resistance in patients with non-insulin-dependent diabetes mellitus.

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.
