Abstract

We evaluated the insulin response to a standard oral glucose tolerance test (OGTT) and in vitro insulin binding to erythrocytes (RBC) in 26 women from 3 groups: Group NW, normal women (n = 11); Group DS, women (n = 9) with elevated serum DHEAS concentrations, greater than 400 micrograms/dl (greater than 10.84 mumol/L); and Group IR, women (n = 6) with elevated basal plasma insulin concentrations (IRI). There was a significant linear correlation between the area under the insulin response curve (IRI-AUC) and serum testosterone (T) (r = 0.78, p = 0.0001). Using stepwise multiple linear regression, IRI-AUC was characterized as a function of both serum T and DHEAS; positively with T and negatively with DHEAS. In vitro (n = 17), there was a positive correlation between RBC-insulin binding and serum DHEAS (r = 0.54, p = 0.029) and a negative correlation between RBC-binding and T (r = -0.57, p = 0.017). We conclude that DHEAS may enhance insulin binding and action and that DHEAS and T have divergent functional relationships with IRI. DHEAS and T may therefore exert opposing effects on insulin secretion and action.

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.
