INTRODUCTION Sex hormones deficiency--hypotestosteronemia (20-30% of men) and dehydroepian-drosterone sulfate deficiency (60-70% of men) are often observed in elderly men. In these men also changes of body composition (visceral obesity, increasing of fat mass), and metabolic disturbances (hypercholesterolemia, hyperinsulinism and insulin resistance) are common disorders. Visceral obesity and in...

BACKGROUND Previous studies suggested that alterations in serum cortisol and DHEA-S levels may play a role in the pathophysiology of schizophrenia. Imbalance in serum cortisol and DHEA-S levels may be related to responsivity to antipsychotic treatment. AIM To compare serum cortisol and DHEA-S levels between patients with schizophrenia and healthy controls and to evaluate their association wit...

Dehydroepiandrosterone (3β-hydroxy-5-androsten-17-one, DHEA), secreted by the adrenal cortex, gastrointestinal tract, gonads, and brain, and its sulfated metabolite DHEA-S are the most abundant endogeneous circulating steroid hormones. DHEA actions are classically associated with age-related changes in cardiovascular tissues, female fertility, metabolism, and neuronal/CNS functions. Early work ...

This study focused on inspecting the relationship between impulsivity traits, salivary dehydroepiandrosterone sulfate (DHEA-S) concentrations, and moderate alcohol consumption in healthy subjects. In previous studies, has been related to androgens. Limited research sulfated form of DHEA-S or impulsivity. Moderate can increase levels. Effects alcohol, androgens levels may depend age gender. The ...

Tuberculosis (TB) remains the most frequent cause of illness and death from an infectious agent, and its interaction with HIV has devastating effects. We determined plasma levels of dehydroepiandrosterone (DHEA), its circulating form DHEA-suphate (DHEA-s) and cortisol in different stages of M. tuberculosis infection, and explored their role on the Th1 and Treg populations during different scena...

Salivary (s)-cortisol, s-amylase, s-DHEA are used extensively in stress research. Vasoactive Intestinal Peptide (VIP) is also detectable in saliva using a standard RIA kit. VIP is a 28 amino acid neuropeptide that belongs to the secretin/glucagon family of peptides and acts as a neurotransmitter/neuromodulator. VIP has also been detected in the parasympathetic nerves enervating the salivary gla...

OBJECTIVES Humans-and several other apes-exhibit a unique pattern of post-natal adrenal maturation; however, the causes and consequences of variation in adrenal development are not well understood. In this study, we examine developmental and age-related maturation of the adrenal gland (measured via dehydroepiandrosterone-sulfate [DHEA-S]) for potential life-history associations with growth and ...

OBJECTIVE Cardiovascular disease (CVD) is the leading cause of mortality and morbidity in patients with type 2 diabetes. Both elevated urinary albumin excretion and low serum concentrations of dehydroepiandrosterone (DHEA) are associated with increased CVD mortality. This raises the possibility of DHEA as a causal intermediate linking urinary albumin excretion to CVD. RESEARCH DESIGN AND METH...

Both elevated urinary albumin excretion (UAE) and low serum concentrations of dehydroepiandrosterone (DHEA) have been linked with increased cardiovascular disease (CVD) mortality in men (1–5). We have recently demonstrated that serum DHEA sulfate (DHEA-S) concentrations correlated inversely with degree of UAE in men with type 2 diabetes (6). However, findings supporting a protective role of DHE...

Neurosteroid dehydropiandrosterone (DHEA) and its sulphate (DHEAS) are reported to have modulatory effects on neuronal excitabillity and synaptic plasticity. DHEA and DHEAS are synthesized in central and peripheral nervous system from cholesterol or steroidal precursors imported from peripheral sources. There is accumulating evidence that alterations in DHEA(S) levels may be involved in the pat...
