Chronic infection with the hepatitis C virus induces liver fibrosis, but it is unknown why some patients progress to advanced fibrosis while others remain with mild disease. Recently, an inverse association between serum levels of dehydroepiandrosterone sulphate (DHEA-S) and liver fibrosis in patients with nonalcoholic fatty liver disease was described and it was postulated that dehydroepiandrosterone (DHEA) has anti-fibrotic effects. Our aim was to compare serum DHEA-S levels with liver fibrosis in hepatitis C patients...

Aging and Alzheimer’s disease (AD) are associated with a declination of cognition and memory, whose severity increases in AD. Recent investigations point to a greater participation of neurofibrillary tangles (NFTs) than that of senile plaques, as responsible for cognitive impairment in AD and normal aging. On the other hand, aging is related with reduced levels of dehydroepiandrosterone (DHEA) and its sulfate (DHEA-S) as well as testosterone (T). Basic and clinical studies give evidence that hypoandrogenism is associated with memory impairment...

Sulfonated steroids (s-St) have been usually regarded as inactive metabolites but are progressively considered as precursors for the intra-tissue formation of bioactive steroids. Moreover, independent effects without preceding removal of the sulfate group have been observed. We use the porcine testicular-epididymal compartment as a model to investigate the still largely unknown s-St physiology as the boar exhibits an intriguingly broad s-St spectrum predominantly originating from the testis. The application of LC-MS/MS in steroidomics enables the determination of unconjugated and intact sulfonated steroids with currently highest specificity and good sensitivity, allowing the concurrent measuring of numerous analytes in larger quantities of samples...

BACKGROUND: Based on studies among primarily male veteran subjects, lipoproteins are thought to mediate the association of posttraumatic stress disorder (PTSD) with cardiovascular disease (CVD). However, recent civilian studies with female samples or samples with both sexes represented provide little evidence for this association. Gender, diet and sex-specific effects of stress hormones on lipoproteins may explain this dissociation in findings. METHOD: Cross-sectional analysis of plasma concentrations of total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL) and triglycerides (TG) in a male and female sample of 49 PTSD-patients due to civilian trauma and 45 healthy controls...

BACKGROUND: Surgical procedures are associated with activation of the hypothalamic-pituitary-adrenal axis (HPA). Studies examining HPA dynamics peri-operatively are limited and the modulating influence of peri-operatively administered glucocorticoids on that is not well established. This investigation examined alterations in HPA function and the impact of dexamethasone (DEX) administration during the peri-operative period. METHODS: We examined HPA function in 297 patients with normal function who had surgical procedures including pituitary mass resection (n = 191), craniotomy (n = 17) and other thoracic/ abdominal/ pelvic surgeries (n = 89)...

BACKGROUND: Over the past several decades, the age of pubertal onset in girls has shifted downward worldwide. As early pubertal onset is associated with increased risky behavior and psychological issues during adolescence and cardiometabolic disease and cancer in adulthood, this is an important public health concern. Exposure to endocrine disrupting chemicals during critical windows of in utero development may play a role in this trend. Our objective was to investigate trimester-specific phthalate and BPA exposure in relation to pubertal development among girls in the Early Life Exposure in Mexico to Environmental Toxicants (ELEMENT) birth cohort...

Vitamin D is essential for mineral homeostasis and contributes to bone metabolism by stimulating osteoblast differentiation of marrow stromal cells (MSCs). In this study, we used MSCs from pre-pubertal girls and boys to test the hypothesis that 1α,25(OH)2D and 17β-estradiol have synergistic effects on these MSCs, and what mechanism is involved. With IRB approval, we isolated MSCs from discarded excess iliac marrow graft from children undergoing alveolar cleft repair. Plasma was available from 8 female (9...

Health outcomes, including chronic disease and mortality, attributed to or associated with alcohol abuse are discrepant between African Americans and Whites. To date, the topic is not fully understood and few studies conducted have used biomarker indicators of health. We investigated whether the association between alcohol abuse and biomarkers of the neuroendocrine system vary between black or African American and White respondents aged 34-84 from the Midlife in the United States Study (MIDUS) II (2004-2006) (n=1129)...

Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system (CNS). Neurosteroids are reported to exert anti-inflammatory effects in several neurological disorders. We investigated the expression and actions of the neurosteroid, dehydroepiandrosterone (DHEA), and its more stable 3β-sulphated ester, DHEA-S, in MS and associated experimental models. CNS tissues from patients with MS and animals with experimental autoimmune encephalomyelitis (EAE) displayed reduced DHEA concentrations, accompanied by diminished expression of the DHEA-synthesizing enzyme CYP17A1 in oligodendrocytes (ODCs), in association with increased expression of inflammatory genes including interferon (IFN)-γ and interleukin (IL)-1β...

Past research has indicated gender differences in the clinical characteristics and course of schizophrenia. In this study, we investigated whether gender differences in the manifestation of schizophrenia are correlated with neurosteroids, including dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEA-S), and pregnenolone. We further explored the potential relationship between the aforementioned neurosteroids and psychopathology. We recruited 65 schizophrenic patients (36 males and 29 females) and 103 healthy control subjects (47 males and 56 females) and obtained blood samples from the subjects in the morning while in a fasting state to determine the serum levels of DHEA, DHEA-S, and pregnenolone...

Differences in hypothalamic-pituitary-adrenocortical (HPA) functioning between patients with posttraumatic stress disorder (PTSD) and controls are among the most consistent neurobiological findings in PTSD. HPA-axis activation results in the output of various steroid hormones including dehydroepiandrosterone (DHEA), which is then converted into dehydroepiandrosterone sulfate (DHEA-S), with anti-glucocorticoid actions among its pleiotropic effects. To investigate whether there is evidence for consistent differences in basal DHEA and DHEA-s levels between individuals with and without PTSD, we performed random-effect meta-analyses aggregating findings of previously published studies...
