We selected 38 patients scheduled for cholecystectomy and studied their serum concentrations of dehydroepiandrosterone (DHEA) and growth axis hormones [growth hormone/insulin-like growth factor-1 (GH/IGF-1)]. We aimed to determine whether alterations in these concentrations resulted from surgical stress or, on the contrary, preceded surgery and were themselves a cause of chronic diseases that r...

Serum levels of cholesterol, phospholipids, beta-lipoproteins, and free fatty acids were correlated with urinary dehydroepiandrosterone (DHEA) excretion in healthy blood donors. An indirect dependence was found for cholesterol and phospholipids that was more important in persons with a low DHEA excretion. The correlation seems to be more a function of the dependence of both DHEA excretion and s...

CONTEXT The age-related decline in dehydroepiandrosterone (DHEA) levels is thought to be of importance for general and vascular aging. However, data on the association between DHEA and mortality are conflicting. OBJECTIVES We tested the hypothesis that low serum DHEA and DHEA sulfate (DHEA-S) levels predict all-cause and cardiovascular disease (CVD) death in elderly men. DESIGN, SETTING, AN...

EpidemiolÃ3gica! and experimental studies suggest that dehydroepiandrosterone (DHEA), an adrenal cortical steroid, has chemoprotective properties. Rat colonie epithelium which had been induced to a premalignant state by the colonie carcinogen azoxymethane was used as a model for patients at high risk of colorectal carcinoma, and the efficacy of dietary DHEA for Chemoprotection against tumorigen...

DHEA (dehydroepiandrosterone) is a hormone often taken as a dietary supplement to prevent the normal decline with age and in the hope of preventing heart attacks. Rats in two experiments were made deficient in copper by standard methods and criteria. Copper deficiency decreased DHEA in serum by approximately 50%. People who associate higher serum concentrations of DHEA with health probably shou...

Abstract The pathophysiology of COVID comprises an exaggerated pro-inflammatory response. Hypothalamic-pituitary-adrenal (HPA) axis has a crucial role in various inflammatory conditions and modulated immunological Limited evidence is available regarding the incidence effect HPA dysfunction COVID-19. Although cortisol levels have only been estimated few studies, dehydroepiandrosterone sulfate (D...

Women with adrenal insufficiency suffer from chronic dehydroepiandrosterone (sulfate) [DHEA(S)] deficiency. To define a suitable dose for DHEA replacement, we studied the pharmacokinetics and biotransformation of orally administered DHEA in nine healthy female volunteers (mean age 23.3 +/- 4.1 yr, mean body mass index 22.5 +/- 1.8 kg/m2) with transient suppression of adrenal androgen secretion ...

Dehydroepiandrosterone (DHEA) is a type of adrenal steroid. The concentrations of DHEA and its sulfate (DHEA-S) in serum reach a peak between the ages of 25 and 30 yr and thereafter decline steadily. It was reported that DHEA-S concentration in humans is inversely related to death from cardiovascular diseases. In this study, we examined the effects of DHEA on regulation of collagen mRNA and col...

The serum levels of an adrenal sex hormone, dehydroepiandrosterone sulfate (DHEA-S), are significantly more decreased in human myelomas compared with the reduction brought by physiologic decline with age. In order to clarify the effect of DHEA on myeloma cells, we investigated whether DHEA and DHEA-S could inhibit interleukin-6 (IL-6) production of bone marrow mononuclear cells and the prolifer...
