Adrenocortical steroids, bone mineral content and endometrial condition in post-menopausal women.
In 23 post-menopausal women, serum levels of cortisol, unconjugated dehydroepiandrosterone (DHA), dehydroepiandrosterone sulphate (DHAS), testosterone, unconjugated and total oestrone and prolactin were measured before and during an ACTH test. Significant positive correlations were found between basal levels of DHA and DHAS; DHA and unconjugated oestrone; DHA and total oestrone; testosterone and total oestrone and between unconjugated and total oestrone. ACTH significantly raised the levels of the steroids but not of prolactin. Significant positive correlations were found between basal levels and ACTH induced increments in DHA; between basal DHAS and increments in DHA and between increments in DHA and DHAS. A significant negative correlation was found between basal levels and increments in cortisol. No significant correlations were found between other combinations of hormone basal levels and/or increments. Significant positive correlations were found between basal levels of DHAS and the DHA response to ACTH respectively, and trabecular bone mineral content of the distal forearm. A significant correlation was also found between bone mineral content and pre-cancerous/cancerous state of the uterine epithelium. The results are a further support to the concept of a link between adrenal androgens and bone mineral density, and do also indicate a relation to endometrial pathology. The lack of correlation between cortisol and other steroids indicate different regulatory mechanisms. Prolactin does not seem to be involved in the regulation of the adrenal androgen synthesis.
