BACKGROUND The observation that dehydroepiandrosterone (DHEA) concentrations decrease markedly with age has led to the hypothesis that declining DHEA concentrations may contribute to age-related changes in cognition. In the United States, DHEA is widely available as an over-the-counter supplement that individuals are using in an effort to ameliorate age-related cognitive and physical changes. ...

Background & Objectives:Endocrine hormones, through their anabolic or catabolic function, contribute in body homeostasis. They can be used to assess the physical performance in athletes. This study was performed to determine the resistance training (RT) influences on serum cortisol and dehydroepiandrosterone in trained young females. Materials & Methods:The study population c...

Background: The nervous, endocrine, and immune systems contribute to the response and dynamic adaption to various stresses. Activation of the hypothalamic-pituitary-adrenal axis has been demonstrated in various active critical illnesses. Novel Coronavirus Disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), is a disease with age and gender disparities...

Dehydroepiandrosterone (DHEA) and DHEA sulfate (DHEAS) are adrenal precursors of steroid biosynthesis and centrally acting neurosteroids. Glucocorticoid and mineralocorticoid deficiencies in Addison's disease require life-long hormone replacement, but the associated failure of DHEA synthesis is not corrected. We conducted a randomized, double blind study in which 39 patients with Addison's dise...

Recent efforts have provided convincing evidence for the use of fish scale cortisol concentration in assessment long-term stress fishes. However, alone is not sufficient to fully describe this state stress. Dehydroepiandrosterone (DHEA) an androgen with actions that oppose those cortisol. The means by which DHEA negates effects occurs part via changes metabolism cortisone. quantitation cortisol...

Serum and plasma dehydroepiandrosterone sulfate (DHEAS) concentration has been associated with several health parameters associated with aging including cognitive function, bone mineral density, and muscular strength. However, the effectiveness of salivary DHEA for the prediction of cognitive function, bone mineral density, and muscular strength in older adults is currently unknown. Thirty elde...

OBJECTIVE Sjögren's syndrome (SS), an autoimmune disease of exocrine glands, typically starts at the time of adrenopause. We undertook this study to test the hypothesis that SS is characterized by an insufficient androgen effect at the target tissue level. METHODS We searched for androgen response elements (AREs) in the cysteine-rich secretory protein 3 (crisp-3) gene. Dehydroepiandrosterone ...

BACKGROUND It is known that long-term psychosocial stress may cause or contribute to different diseases and symptoms and accelerate aging. One of the consequences of prolonged psychosocial stress may be a negative effect on the levels of dehydroepiandrosterone (DHEA) and its sulphated metabolite dehydroepiandrosterone sulphate (DHEA-S). The aim of this study is to investigate whether levels of ...

To determine whether alterations in adrenocortical function occur early in the development of inflammatory joint disease, we examined patients with new onset synovitis (<1 yr) prior to treatment with corticosteroids or other disease-modifying antirheumatic drugs. Thirty-two patients with new onset synovitis, including 15 fitting criteria for rheumatoid arthritis (RA), taking no medications, wer...

Dehydroepiandrosterone (DHEA) and its sulfate (DHEAS) are hormones produced by the adrenal cortex that decline in concentration with age. Decreased DHEA levels are associated with age-related disease and oxidative stress but might be increased in younger adults by exercise. Studies are presented assessing the response of DHEA and DHEAS to varied-intensity exercise in older age. DHEA increased s...
