OBJECTIVES This single-dose study compares three dehydroepiandrosterone delivery methods (oral crystalline steroid, micronized steroid, and vaginal administration) to ascertain whether physiologic levels of circulating dehydroepiandrosterone and dehydroepiandrosterone sulfate can be obtained while increases in testosterone are minimized. STUDY DESIGN Two randomized, double-blind, placebo-cont...

In humans, dehydroepiandrosterone and its sulfate ester metabolite DHEA-S are secreted predominantly from the adrenal cortex, and dehydroepiandrosterone is converted to steroid hormones, including androgens and estrogens, and neurosteroid. Dehydroepiandrosterone exerts protective effects against several pathological conditions. Although there are reports on the association between dehydroepiand...

A basic understanding of the distinct metabolism, mechanism of action, and clinical use of dehydroepiandrosterone and its metabolites is critical to balancing the hormone milieu in postmenopausal women. To date, studies of dehydroepiandrosterone therapy in women with adrenal insufficiency suggest that they are the most likely group to gain health benefits from dehydroepiandrosterone replacement...

OBJECTIVE It has been reported that dehydroepiandrosterone is a pulmonary vasodilator and inhibits chronic hypoxia-induced pulmonary hypertension. Additionally, dehydroepiandrosterone has been shown to improve systemic vascular endothelial function. Thus, we hypothesized that chronic treatment with dehydroepiandrosterone would attenuate hypoxic pulmonary hypertension by enhancing pulmonary arte...

7-hydroxy/oxo derivatives of dehydroepiandrosterone are potential regulators of the local cortisol activity due to their competition in the cortisolcortisone balance mediated by 11ß-hydroxysteroid dehydrogenase. 7-hydroxy-dehydroepiandrosterone is marketed as anti-obesity medication, though no clinical study aimed at the benefit of administering 7...

to evaluate the maternal serum dehydroepiandrosterone sulfate level as a factor associated with the outcome of labor induction. venous blood was collected from 45 women at the initiation of labor induction. pregnancies complicated by maternal corticosteriod use, anterpartum chorioamnionitis, or cesarean delivery for indications other than arrest disorders, were excluded from analysis. in 42 wom...

Dehydroepiandrosterone and dehydroepiandrosterone sulfate are steroids which may be associated with the development of breast cancer. To examine the association between serum levels of dehydroepiandrosterone and dehydroepiandrosterone sulfate and the risk of developing premenopausal breast cancer, we measured hormone levels in 15 women who donated blood to a community-based serum bank in 1974 a...

Dehydroepiandrosterone may influence thyroid function. Its metabolite, 7-oxo-dehydroepiandrosterone, a precursor of immunomodulatory 7-hydroxylated metabolites and thermogenic agent, belongs to candidates of steroid replacement therapy. The question was addressed whether its application does influence laboratory parameters of thyroid function. 7-Oxo-dehydroepiandrosterone in the form of emulgel...

Dehydroepiandrosterone sulphate is one of the most important neurosteroids. In the present paper, we studied the effect of dehydroepiandrosterone sulphate on persistent sodium currents and its mechanism and functional consequence with whole-cell patch clamp recording method combined with a pharmacological approach in the rat medial prefrontal cortex slices. The results showed that dehydroepiand...
