Prolactin modulation of dehydroepiandrosterone sulfate secretion

Abstract

To clarify the controversy about the effect of prolactin (PRL) on dehydroepiandrosterone sulfate (DHEA-S), this study was undertaken to investigate the effects of alterations in plasma PRL on plasma DHEA-S concentrations in hyperprolactinemic women, as well as in normal male subjects. DHEA-S was measured in a group of 21 women with hyperprolactinemia, galactorrhea, and amenorrhea (PRL:257 +/- 89 ng/ml; mean +/- SEM). In these women, mean plasma concentrations of DHEA-S (2.54 +/- 0.2 microgram/ml) were significantly higher (p < 0.005) than those in 41 normal control women (1.78 z microgram/ml) and those in a group of 11 amenorrheic patients (1.77 +/- 0.2 microgram/ml). Eight women with hyperprolactinemia were given 5 mg of bromocriptine each day for 4 consecutive weeks. Within 1 week of medication, PRL levels fell by 60% (p < 0.05). To test whether lowering normal plasma levels of PRL would affect plasma concentrations of DHEA-S, five normal male subjects received a 48-hour infusion of dopamine at an average rate of 6 microgram/kg/min. Plasma levels of PRL fell by 60% (p < 0.01) after 8 hours of infusion, and DHEA-S decreased by 27% by 16 hours (p < 0.05). These data suggest that PRL modulates the secretion of DHEA-S: an increase in plasma levels of PRL is correlated with elevated concentrations of DHEA-S, whereas a decrease in PRL is followed by a fall in DHEA-S.

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.
