  • Dehydroepiandrosterone-sulfate (DHEAS) promotes MIN6 cells insulin secretion via inhibition of AMP-activated protein kinase - Biochem Biophys Res Commun. 2013 Oct 8 - "Although it has the property of anti-diabetes, the long-term effect of DHEAS on insulin secretion in beta-cells is still unclear. In this study, the effect of DHEAS on the insulin secretion activity in MIN6 cell lines in vitro was assessed. Insulin biosynthesis and secretion were stimulated by DHEAS for 24 h. DHEAS inhibited the AMPK activation and upregulated the expression of ACC-1. These findings indicate that DHEAS may exert prominent stimulatory effects on insulin secretion partly via AMPK inhibition and ACC-1 upregulation"

  • Low Dehydroepiandrosterone Sulfate is Associated With Increased Risk of Ischemic Stroke Among Women - Stroke. 2013 May 23 - "Between 1989 and 1990, 32 826 women without prior stroke in the Nurses' Health Study, an observational cohort, provided blood samples and were followed up for cardiovascular events ... Conditional on matching factors, the lowest DHEAS quartile exhibited a relative risk of 1.30 for ischemic stroke (95% confidence interval, 0.88-1.94), compared with the highest quartile and marginally unchanged when adjusted for confounders (relative risk=1.33; 95% confidence interval, 0.87-2.02). When modeled as a binary variable dichotomized at the lowest quartile, women with low DHEAS (≤the lowest quartile) had a significantly increased multivariable adjusted risk of ischemic stroke compared with those with higher levels (relative risk=1.41; 95% confidence interval, 1.03-1.92)"
  • A Randomized Double-Blinded Placebo-Controlled Trial on the Effect of Dehydroepiandrosterone for 16 Weeks on Ovarian Response Markers in Women with Primary Ovarian Insufficiency - J Clin Endocrinol Metab. 2012 Nov 8 - "Preliminary reports have shown encouraging effects of dehydroepiandrosterone (DHEA) in women with poor ovarian reserve undergoing assisted reproduction and primary ovarian insufficiency (POI), although data from randomized controlled trials are limited ... Eligible subjects were randomized into the DHEA group (n = 10), who received DHEA (LiveWell, 25 mg three times a day), or the placebo group (n = 12), who received placebo for 16 wk according to a computer-generated randomization list ... No significant change in serum AMH and FSH levels had been detected throughout the study. AFC and ovarian volume were significantly higher at wk 12 and 20, respectively, in the DHEA group. Significantly more women having at least one follicle of 10 mm or greater at wk 12, 16, and 20 were found in the DHEA group. Serum testosterone and DHEA sulfate levels along with higher estradiol levels were significantly higher in the DHEA group"
  • The use of dehydroepiandrosterone in the treatment of hypoactive sexual desire disorder: A report of gender differences - Eur Neuropsychopharmacol. 2012 Oct 17 - "Data regarding the efficacy of dehydroepiandrosterone (DHEA) in the treatment of hypoactive sexual desire disorder (HSDD) are scarce and inconsistent. We aimed to determine possible gender differences in the efficacy of DHEA as a treatment for HDSS. Postmenopausal women (n=27), and men (n=21) with HSDD, were randomized to receive either DHEA 100mg daily or placebo for 6 weeks in a controlled, double blind study ... In women only, significant interaction effects were observed for sexual arousal (p<0.05), satisfaction (p<0.05), and cognition (trend; p=0.06). For arousal, a significant improvement was observed for the DHEA treated group at 6 weeks (p=0.001). Significant correlations were observed between bioavailable T and sexual cognitions, arousal and orgasm, while DHEAS was correlated with satisfaction. In the men, significant correlations were observed between testosterone and arousal (r=.45), sexual drive (r=.50) and orgasm (r=.55). In women with HSDD, DHEA treatment had a significant beneficial effect on arousal, whereas no efficacy was demonstrated in men, indicating a possible gender difference. This improvement seems to be mediated via DHEA's metabolism to testosterone. Our positive results suggest that the neurosteroid DHEA may be effective as a treatment for women with HSDD if administered at a dose of at least 100mg per day"
  • Diferential Effect of Oral Dehydroepiandrosterone-Sulphate on Metabolic Syndrome Features in Pre- and Postmenopausal Obese Women - Clin Endocrinol (Oxf). 2011 Dec 2 - "To analyze the effect in obese pre- and postmenopausal women of a daily dose of 100 mg Dehydroepiandrosterone-sulphate (DHEA-S) provided over a period of 3 months as replacement therapy against Metabolic-Syndrome ... DHEA-S replacement produced weight loss in the obese women studied. Moreover, waist-circumference, glucose and systolic and diastolic blood pressure, among other Metabolic-Syndrome parameters, improved in the postmenopausal group, who showed a significant reduction in the total Metabolic-Syndrome Score (P<0.05). In contrast, in premenopausal women, the effect of DHEA-S was limited to obesity parameters and no effect was observed on Metabolic-Syndrome components. No significant changes were evident in the placebo group. Conclusions:  An oral dose of DHEA-S is useful for weight loss. In obese postmenopausal women the hormone significantly improves plasma biochemical levels and anthropometric characteristics, leading to a better metabolic profile, which highlights the usefulness of this therapy against Metabolic-Syndrome in this group of women"

The present analyses provide confirmation of a positive association between cortisol and the cortisol:DHEAS ratio and population hypertension"
  • Dehydroepiandrosterone combined with exercise improves muscle strength and physical function in frail older women - J Am Geriatr Soc. 2010 Sep;58(9):1707-14 - "DHEA supplementation resulted in gains in lower extremity strength (from 459 +/- 121 N to 484 +/- 147 N; P=.01). There was also improvement in Short Physical Performance Battery score, a composite score that focuses on lower extremity function, in those taking DHEA (from 10.1 +/- 1.8 to 10.7 +/- 1.9; P=.02). There were significant changes in all hormone levels, including DHEAS, estradiol, estrone, and testosterone, and a decline in sex hormone-binding globulin levels in those taking DHEA ... CONCLUSION: DHEA supplementation improved lower extremity strength and function in older, frail women involved in a gentle exercise program of chair aerobics or yoga. No changes were found in BMD either due to small sample size, short duration of study or no effect. The physical function findings are promising and require further evaluation as frail women are at high risk for falls and fracture"
  • DHEA-S Levels and Cardiovascular Disease Mortality in Postmenopausal Women - J Clin Endocrinol Metab. 2010 Aug 25 - "Women in the lowest DHEA-S tertile had higher CVD mortality (17% 6-yr mortality rate vs. 8%; log-rank P = 0.011), and all-cause mortality (21 vs. 10%; P = 0.011) compared with women with higher DHEA-S levels. The increased CVD mortality risk [hazard ratio (HR) = 2.55; 95% confidence interval (CI) = 1.19-5.45] remained unchanged after adjustment for multiple CVD risk factors (HR = 2.43; 95% CI = 1.06-5.56) but became nonsignificant when further adjusting for the presence or severity of angiographic obstructive CAD (HR = 1.99; 95% CI = 0.87-4.59). Results were similar for all-cause mortality. Lower DHEA-S levels were only marginally but not independently associated with obstructive CAD"
  • Protective effects of dehydroepiandrosterone on atherosclerosis in ovariectomized rabbits via alleviating inflammatory injury in endothelial cells - Atherosclerosis. 2010 Aug 3 - "The risk for atherosclerosis is increased in postmenopausal women. Dehydroepiandrosterone (DHEA) is postulated to have anti-atherogenic properties ... DHEA administration alleviates efficiently the early pathologic damage of atherosclerosis, increases the serum NO level, and up-regulates the endothelial cell estrogen receptor (ER) expression of ovariectomized rabbits. DHEA in vitro significantly promotes NO synthesis, suppresses MDA and MCP-1 secretion of endothelial cells, and decreases ICAM-1, VCAM-1 and E-selectin expression in HUVECs; neither selective ERα antagonist (methyl-piperidino-pyrazole, MPP) nor ERβ antagonist (R,R-tetrahydrochrysene, R,RTHC) can abolish these effects. Furthermore, DHEA reduces CCR2, LFA-1 and VLA-4 expression in U937 cells, which in turn inhibits the adherence of monocytes to the injured endothelial cells. DHEA significantly decreased the LPS-induced NF-κB transcription"
  • Role of androgens in women's sexual dysfunction - Menopause. 2010 Jun 8 - "Significantly lower levels of two precursor hormones, dehydroepiandrosterone sulfate and androstene-3beta,17beta-diol, were found in women with sexual dysfunction ... Although the significance of the former awaits further study, androgen deficiency in women with HSDD was not confirmed. Given the unknown long-term effects of testosterone supplementation, women receiving testosterone therapy should be informed that a deficit of testosterone activity in women with HSDD has not been identified"
  • Elevated serum dehydroepiandrosterone sulphate level correlates with increased risk for metabolic syndrome in the elderly men - Eur J Clin Invest. 2009 Dec 30 - "The highest DHEA-S quartile group had increased risk for metabolic syndrome (odds ratio = 2.68, 95% confidence interval: 1.44-5.01, P < 0.01) compared with the lowest quartile group. The mean serum DHEA-S level increased with increasing number of metabolic syndrome components. Conclusions The prevalence of metabolic syndrome increases with elevated DHEA-S levels among elderly Taiwanese men. Thus, elevated serum DHEA-S level should be treated as an important risk factor for metabolic syndrome in elderly men"

  • Serum steroid levels during 12-week intravaginal dehydroepiandrosterone administration - Menopause. 2009 May 8 - "The present data show that local daily intravaginal DHEA administration at DHEA doses of 3.25-13 mg was able to rapidly and efficiently achieve correction of all the signs and symptoms of vaginal atrophy and improve sexual function and caused no or minimal changes in serum sex steroid levels, which all remain within the normal postmenopausal range, thus avoiding the risks of all estrogen formulations"
  • Intravaginal dehydroepiandrosterone (Prasterone), the physiological and a highly efficient treatment of vaginal atrophy - Menopause. 2009 May 8 - "All three doses (0.25%, 0.5%, and 1.0%) of DHEA ovules applied daily intravaginally induced a highly significant beneficial change in the percentage of vaginal parabasal and superficial cells and pH as well as in the most bothersome symptom at 2 weeks. At the standard 12-week time interval, 0.5% DHEA caused a 45.9 +/- 5.31 (P < 0.0001 vs placebo) decrease in the percentage of parabasal cells, a 6.8 +/- 1.29% (P < 0.0001) increase in superficial cells, a 1.3 +/- 0.13 unit (P < 0.0001) decrease in vaginal pH, and a 1.5 +/- 0.14 score unit (P < 0.0001) decrease in the severity of the most bothersome symptom. Similar changes were seen on vaginal secretions, color, epithelial surface thickness, and epithelial integrity. Comparable effects were observed at the 0.25% and 1.0% DHEA doses ... Local Prasterone, through local androgen and estrogen formation, causes a rapid and efficient reversal of all the symptoms and signs of vaginal atrophy with no or minimal changes in serum steroids, which remain well within the normal postmenopausal range. This approach avoids the fear of systemic effects common to all presently available estrogen formulations and adds a novel physiological androgenic component to therapy"
