Depressed Plasma FFA Turnover Rate in Cushing’s Syndrome
Abstract
The turnover rate of plasma FFA measured by constant infusion of albumin-complexed labeled palmitate in a group of 16 patients with Cushing's syndrome was significantly lower than in a group of 6 controls. Seven patients reexamined after correction of the hypercortisolism showed a normalization of the plasma FFA turnover rate. By contrast, 7 patients with simple obesity had a normal or increased plasma FFA turnover rate depending on the way this parameter is expressed.

Chronic GC excess does not necessarily increase whole-body lipolysis.
“The high GC phase only partially antagonized the insulin‐mediated suppression of lipolysis; thus, cortisol‐induced hyperinsulinaemia may offset this effect, which may explain why chronic GC excess does not necessarily increase whole‐body lipolysis.32, 33”
From Acute physiological effects of glucocorticoids on fuel metabolism in humans are permissive but not direct (2017) · cites this paper as [33]
In studies addressing the effects of chronic GC treatment, typically no changes were observed in whole-body lipolysis in the fasted state, and fasting insulin levels were increased.
“In studies addressing the effects of chronic GC treatment, typically no changes were observed in whole-body lipolysis in the fasted state [32], and fasting insulin levels were increased [33, 34].”

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.
