The small apes, gibbons and siamangs, are monogamous species with their social groups comprising of both parents and their offspring. Therefore, the loss of a member may elicit a stress response in the remaining members due to their strong bonds. Glucocorticoids (GCs) have been useful indicators of stress, but distinguishing between acute versus chronic stress may be limited when measuring these hormones alone. The adrenal hormone dehydroepiandrosterone-sulfate (DHEAS), a GC antagonist, has been implicated in the regulation of the stress response. Thus, the concomitant measurement of these hormones can help examine whether an event, such as the loss of a group member, elicited a stress response. In this brief report, we discuss the hormonal response of two zoo-housed northern white-cheeked gibbons (Nomascus leucogenys) (1 adolescent male and his mother) after the death of the adult male of the group. Baseline fecal samples were collected opportunistically from these two individuals 5 months prior, and 3 months following the death of their group member. A total of 25 samples were quantified for fecal GC metabolites (FGCMs) and DHEAS by enzyme immunoassay (EIA) to calculate the FGCMs:DHEAS ratio. Our results indicate an increase in FGCMs and FGCMs:DHEAS for the adolescent male, but not the adult female, following the death. Our findings suggest that the integration of FGCMs and DHEAS measurements can provide valuable information to interpret individual stress levels to the sudden change in the group's social structure.

Background: There are indications for sex-specific differences regarding the association between kallikrein-8 (KLK8) and cognitive impairment in early stages of Alzheimer's disease for which KLK8 may be an early blood-based biomarker. These may be due to different levels of sex hormones. To correctly interpret KLK8 blood concentrations, sex-specific analyses are needed. Objective: The aim of our exploratory study was to investigate sex-specific differences in blood-based KLK8 in participants of the population-based Heinz Nixdorf Recall study with different cognitive status and the association between KLK8 and sex hormones. Methods: In 290 participants (45% women, 69.7±7.4 years (mean±SD)) we investigated sex-specific serum KLK8 differences between cognitively unimpaired (CU, 43%) and cognitively impaired (CI) participants and the association between KLK8 and dehydroepiandrosteronsulfate (DHEAS), estradiol and testosterone, using adjusted multiple linear regression. Results: The mean±SD KLK8 was similar for CU men (808.1±729.6 pg/ml) and women (795.9±577.7 pg/ml); adjusted mean-difference [95%-CI]: –95.3 [–324.1;133.5] pg/ml. KLK8 was lower in CI women (783.5±498.7 pg/ml) than men (1048.4±829 pg/ml); –261 [–493.1; –29] pg/ml. In men but not women, there was a weak indication for a positive slope between estradiol (11.9 [–0.4;24.3] pg/ml) and DHEAS (1.4 [–0.5;3.3] pg/ml) with KLK8, while testosterone had no impact. Conclusions: The results suggested a different role for KLK8 in the development of cognitive impairment in men and women, potentially influenced by sex hormones. To use blood KLK8 as an early biomarker, further research on hormonal regulation of KLK8 expression is needed as a part of the investigation of the KLK8 involvement in cognitive impairment and Alzheimer's disease pathology.

3'-Phosphoadenosine 5'-phosphosulfate synthase 2 (PAPSS2) deficiency is a rare disorder due to biallelic pathogenic variants in the PAPSS2 gene. This disorder was first described in 1998 by Ahmad et al. and Faiyaz ul Haque et al. To date, 79 patients with PAPSS2 deficiency have been reported. The main reported features of these patients are related to bone abnormalities and clinical/biochemical androgen excess. Disproportionate short stature and symptoms associated with spondylar skeletal dysplasia are the most common clinical features that require clinical attention. Androgen excess has been described much less commonly. This review summarizes the currently published clinical, molecular, and biochemical features of patients with PAPSS2 deficiency.

To evaluate the initial impact of a combined oral contraceptive (COC) containing norgestimate (NGM) on female sexuality and on circulating androgen levels in users. Six months modification in the McCoy Female Sexuality Questionnaire (MFSQ) and testosterone (T) and dehydroepiandrosterone sulphate (DHEAS) serum levels in women starting a monophasic pill containing ethinyl-estradiol (EE) 35 µg and NGM 0.250 mg. The study was completed by 36 subjects. There was a significant increase in MFSQ during treatment (p < 0.0001) (and its domains with the exclusion of vaginal lubrication domain) with concomitant decreases in T (−4.45%, p < 0.0001) and DHEAS (−19.41%, p < 0.0001) serum levels. Contraception with EE/NGM was associated with a short term non-deteriorating effect on sexuality despite the evident decrease in androgen levels. Female sexuality during COC use is a complex topic and is not only linked with changes in serum androgen levels. EE/NGM treatment has a short term non-deteriorating effect on sexuality despite the evident decrease in androgen serum levels. [ABSTRACT FROM AUTHOR]

Dehydroepiandrosterone sulphate (DHEAS), the biochemical indicator of adrenarche and pubarche, is of paramount importance in the evaluation of puberty-related disorders. The reference range of DHEAS should be ethnicity, age, sex, pubarche and Tanner stage specific. Anthropometry, puberty assessment and hormonal parameters were estimated using electrochemiluminescence assay. Bone age was estimated using the BoneXpert software. Of 2191 healthy Indian children aged 5–18 y screened at Chandigarh, 1919 were included in the final analysis (994 boys). The median DHEAS levels at pubarche stage P2 were 82.10 (55.0–129.0) g/dl in girls and 132.50 (95.12–205.50) g/dl in boys. By ROC analysis, the level of DHEAS at pubarche was 63.7 g/dl (sensitivity 72.6%, specificity 64.4%) in girls and 82.2 g/dl (sensitivity 81.8%, specificity 68.8%) in boys. The median age at adrenarche was 9.5 y in both sexes. On multivariate regression analysis; bone age, body mass index (BMI), gonadal steroids, and insulin-like growth factor-1 (IGF-1) significantly correlated with serum DHEAS levels in either sex.

Context: Childhood overweight has been linked to earlier development of adrenarche and puberty, but it remains unknown if lifestyle interventions influence sexual maturation in general populations. Objective: To investigate if a 2-year lifestyle intervention influences circulating androgen concentrations and sexual maturation in a general population of children. Methods: We conducted a 2-year physical activity and dietary intervention study in which 421 prepubertal and mostly normal-weight 6- to 9-year-old children were allocated either to a lifestyle intervention group (119 girls, 132 boys) or a control group (84 girls, 86 boys). The main outcome measures were serum dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), androstenedione (A4), and testosterone concentrations, and clinical adrenarchal and pubertal signs. Results: The intervention and control groups had no differences in body size and composition, clinical signs of androgen action, and serum androgens at baseline. The intervention attenuated the increase of DHEA (P = .032), DHEAS (P = .001), A4 (P = .003), and testosterone (P = .007) and delayed pubarche (P = .038) in boys but it only attenuated the increase of DHEA (P = .013) and DHEAS (P = .003) in girls. These effects of lifestyle intervention on androgens and the development of pubarche were independent of changes in body size and composition, but the effects of intervention on androgens were partly explained by changes in fasting serum insulin. Conclusion: A combined physical activity and dietary intervention attenuates the increase of serum androgen concentrations and sexual maturation in a general population of prepubertal and mostly normal-weight children, independently of changes in body size and composition.

Biochemical premature adrenarche is defined by elevated serum DHEAS [≥40 μg/dL] before age 8 y in girls. This condition is receiving more attention due to its association with obesity, hyperinsulinemia, dyslipidemia, and polycystic ovary syndrome. Nevertheless, the link between early androgen excess and these risk factors remains unknown. Epigenetic modifications, and specifically DNA methylation, have been associated with the initiation and progression of numerous disorders, including obesity and insulin resistance. The aim of this study was to determine if prepubertal androgen exposure is associated with a different methylation profile in pubertal girls. Eighty-six healthy girls were studied. At age 7 y, anthropometric measurements were begun and DHEAS levels were determined. Girls were classified into Low DHEAS (LD) [

Background: The reproductive system is heavily dependent on ovarian follicles, which are made up of germ cells (oocytes) and granulosa cells (GCs), including cumulus granulosa cells (CGCs) and mural granulosa cells (MGCs). Understanding their normal and steroid-induced functions is the key to understanding the pathophysiology of endocrinal diseases in women. Objective: This study investigated the differentially expressed proteins by CGCs and MGCs of patients with polycystic ovarian syndrome (PCOS) and without subsequent exposure to dehydroepiandrosterone sulfate (DHEAS) and functional differentiation. Design: The present study was observational and experimental study carried out in hospital involving 80 female patients undergoing IVF for infertility. Methods: In this study, we isolated CGCs and MGCs from the follicular fluid of both PCOS and non-PCOS patients undergoing in vitro fertilization (IVF). The cells were cultured and treated with DHEAS for 48 hours, and these cells were extracted, digested, and analyzed by tandem mass spectrometry followed by processing of the results using open-source bioinformatics tools. Results: The present investigation discovered 276 and 341 proteins in CGCs and MGCs, respectively. DHEAS reduced the number of proteins expressed by CGCs and MGCs to 34 and 57 from 91 and 94, respectively. Venn results of CGCs revealed 49, 53, 36, and 21 proteins in normal CGCs, PCOS-CGCs, post-DHEAS, and PCOS-CGCs, respectively. Venn analysis of MGCs showed 51 proteins specific to PCOS and 29 shared by normal and PCOS samples after DHEAS therapy. MGCs express the most binding and catalytic proteins, whereas CGCs express transporter-related proteins. A protein pathway study demonstrated considerable differences between normal and PCOS samples, while DHEAS-treated samples of both cell lines showed distinct pathways. String findings identified important network route components such as albumin, actin, apolipoprotein, complement component C3, and heat shock protein. Conclusion: This is the first study to show how DHEAS-induced stress affects the expression of proteins by MGCs and CGCs isolated from normal and PCOS patients. Further studies are recommended to identify PCOS biomarkers from CGCs and MGCs expressed under the influence of DHEAS. Graphical abstract [ABSTRACT FROM AUTHOR]

Context: The relationship between dehydroepiandrosterone sulfate (DHEAS) and mortality is of scientific and public health interest, yet it remains poorly understood. Objective: We examined the association between DHEAS and mortality from cancer, cardiovascular disease, and all causes in middle-aged and older men and women. Methods: DHEAS was measured in stored serum samples collected from 1994 to 1998 from a case-cohort nested within EPIC-Heidelberg, that included 7370 men (mean age=55.0) and women (mean age= 52.4 years). Median follow-up for incident mortality events was 17.7 years. All deaths due to cancer (n=1040), cardiovascular diseases (n= 598), and all causes (n=2407) that occurred in EPIC-Heidelberg until end of 2014 were included. Results: The association between DHEAS and mortality was nonlinear such that both participants in the lowest (Q1) and highest (Q5) sex- and 5- year age-group specific quintiles of DHEAS were at increased hazard ratios (HR) of mortality from cardiovascular [Q1: HR=1.83 (95% CI: 1.33- 2.51), Q5: 1.39 (1.00-1.94)], cancer [Q1: 1.27 (1.01-1.60), Q5: 1.27 (1.02-1.60)] and all causes [Q1: 1.51 (1.25-1.82), Q5: 1.31 (1.08-1.58)], compared with participants in Q3. In men and women with below-median DHEAS levels, doubling of DHEAS was associated with lower hazards of cardiovascular [0.87, (0.78-0.96)], cancer [0.90, (0.83-0.97)], and total mortality [0.89, (0.83-0.95)]. In contrast, a doubling in DHEAS among participants with above-median levels was associated with 1.20, (1.01-1.42), 1.28, (1.01-1.62), and 1.19 (1.03-1.37) higher hazards of mortality from cancer, cardiovascular, and all causes, respectively. Conclusion: In this large population-based study, DHEAS showed a J-shaped association with mortality. Both participants with lowest and highest levels experienced higher hazards of mortality from cancer, cardiovascular disease, and all causes. [ABSTRACT FROM AUTHOR]

Context: Polycystic ovary syndrome (PCOS) is a complex endocrine disease that affects women of reproductive age and is characterised by biochemical and clinical androgen excess. Aim: To evaluate the efficacy of pharmacological interventions used to decrease androgen hormones in women with PCOS. Data source: We searched PubMed, MEDLINE, Scopus, Embase, Cochrane library and the Web of Science from inception up to March 2021. Data synthesis: Two reviewers selected eligible studies and extracted data, and the review is reported according to the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Results: Of the 814 randomised clinical trials (RCTs) located in the search, 92 met the eligibility criteria. There were significant reductions in total testosterone level with metformin versus (vs) placebo (SMD: − 0.33; 95% CI − 0.49 to − 0.17, p < 0.0001, moderate grade evidence) and dexamethasone vs placebo (MD:-0.86 nmol/L; 95% CI − 1.34 to − 0.39, p = 0.0004, very low-grade evidence). Significant reductions in the free testosterone with sitagliptin vs placebo (SMD: − 0.47; 95% CI − 0.97 to 0.04, p = 0.07, very low-grade evidence), in dehydroepiandrosterone sulphate (DHEAS) with flutamide vs finasteride (MD: − 0.37 µg/dL; 95% CI − 0.05 to − 0.58, p = 0.02, very low-grade evidence), a significant reduction in androstenedione (A4) with rosiglitazone vs placebo (SMD: − 1.67; 95% CI − 2.27 to − 1.06; 59 participants, p < 0.00001, very low-grade evidence), and a significant increase in sex hormone-binding globulin (SHBG) with oral contraceptive pill (OCP) (35 µg Ethinyl Estradiol (EE)/2 mg cyproterone acetate (CPA)) vs placebo (MD: 103.30 nmol/L; 95% CI 55.54–151.05, p < 0.0001, very low-grade evidence) were observed. Conclusion: Metformin, OCP, dexamethasone, flutamide, and rosiglitazone use were associated with a significant reduction in biochemical hyperandrogenemia in women with PCOS, though their individual use may be limited due to their side effects.

Introduction: Some but not all women with polycystic ovary syndrome (PCOS) develop the metabolic syndrome (MS). The objective of this study was to determine if a subset of women with PCOS had higher androgen levels predisposing them to MS and whether routinely measured hormonal parameters impacted the metabolic syndrome score (siMS). Methods: We included data from a discovery (PCOS clinic data) and a replication cohort (Hull PCOS Biobank) and utilized eight routinely measured hormonal parameters in our clinics (free androgen index [FAI], sex hormone‐binding globulin, dehydroepiandrosterone sulphate (DHEAS), androstenedione, luteinizing hormone [LH], follicular stimulating hormone, anti‐Müllerian hormone and 17 hydroxyprogesterone [17‐OHP]) to perform a K‐means clustering (an unsupervised machine learning algorithm). We used NbClust Package in R to determine the best number of clusters. We estimated the siMS in each cluster and used regression analysis to evaluate the effect of hormonal parameters on SiMS. Results: The study consisted of 310 women with PCOS (discovery cohort: n = 199, replication cohort: n = 111). The cluster analysis identified two clusters in both the discovery and replication cohorts. The discovery cohort identified a larger cluster (n = 137) and a smaller cluster (n = 62), with 31% of the study participants. Similarly, the replication cohort identified a larger cluster (n = 74) and a smaller cluster (n = 37) with 33% of the study participants. The smaller cluster in the discovery cohort had significantly higher levels of LH (7.26 vs. 16.1 IU/L, p <.001), FAI (5.21 vs. 9.22, p <.001), androstenedione (3.93 vs. 7.56 nmol/L, p <.001) and 17‐OHP (1.59 vs. 3.12 nmol/L, p <.001). These findings were replicated in the replication cohort. The mean (±SD) siMS score was higher in the smaller cluster, 3.1 (±1.1) versus 2.8 (±0.8); however, this was not statistically significant (p =.20). In the regression analysis, higher FAI (β =.05, p =.003) and androstenedione (β =.03, p =.02) were independently associated with a higher risk of SiMS score, while higher DHEAS levels were associated with a lower siMS score (β = −.07, p =.03) Conclusion: We identified a subset of women in our PCOS cohort with significantly higher LH, FAI, and androstenedione levels. We show that higher levels of androstenedione and FAI are associated with a higher siMS, while higher DHEAS levels were associated with lower siMS. [ABSTRACT FROM AUTHOR]

Abstract Background The source of excess androgen can be obscure in postmenopausal women with new-onset hyperandrogenism. If serum dehydroepiandrosterone sulphate (DHEAS) is raised, it is presumed to be of adrenal origin because DHEAS is exclusively produced from adrenal cortical cells. This reports an elderly female presenting with new-onset hyperandrogenism due to an ovarian sex cord-stromal tumour, associated with increased serum DHEAS levels. Case description A 76-year-old female with long-standing diabetes and hypertension presented with hirsutism and male type alopecia for six months. She had menopause at 55 years of age. There was a pelvic mass on examination. Total testosterone was 6.106 ng/ml (0.124–0.357) and DHEAS was > 1000 µg/dL (35–430). Contrast-enhanced computed tomography of the abdomen and pelvis showed a heterogeneously enhancing complex mass measuring 11 × 8 cm in the left adnexal region. Adrenal glands were normal. She underwent total abdominal hysterectomy, bilateral salphingo-oophorectomy, and omentectomy. Both testosterone and DHEAS normalised following surgery. Histology revealed a sex cord-stromal tumour, likely a steroid cell tumour with malignant potential. Fluorodeoxyglucose-Positron emission tomography did not show any additional lesions. Conclusions Due to the lack of sulfotransferase in ovarian tissue, markedly elevated DHEAS originating from an ovarian neoplasm is unusual. This phenomenon has not been described except in a patient with a steroid cell tumour causing Cushing syndrome and hyperandrogenism. The mechanism of this rare occurrence remains elusive. Knowledge of this unusual presentation would enable the clinicians to be cautious in localising the androgen source in women with hyperandrogenism.

Objective/design: Testosterone might mediate sex differences in kidney function and chronic kidney disease (CKD). However, few studies analyzing the association between testosterone and kidney function showed conflicting results. Therefore, we performed a systematic review and meta-analysis. Methods: Six electronic databases were searched from inception to March 4, 2020, for studies that investigated the association of (i) testosterone status with kidney function in the general population or (ii) testosterone status with clinical outcomes (kidney function decline, kidney failure, cardiovascular (CV) events, and cardiovascular and all-cause mortality) in CKD patients. We used random and fixed-effect models to obtain pooled effect estimates with 95% confidence intervals (CIs). Results: No randomized–controlled trials that met the inclusion criteria were identified. One study was conducted in the general population and reported an increased risk of incident CKD with low vs normal testosterone (hazard ratio (HR): 1.38, 95% CI: 1.05;1.80). Seven studies were conducted in men with CKD and included testosterone as determinant, of which six could be meta-analyzed. Low testosterone was associated with an increased risk of all-cause mortality and CV events (pooled HR: 1.98, 95% CI: 1.36;2.89; pooled HR of 2.40, 95% CI: 1.22;4.71, respectively). Two studies showed an increased risk of all-cause mortality with decreased dehydroepiandrosterone sulfate (DHEAS) in men with CKD; results regarding CV events were conflicting. Conclusions: Although literature is scarce, evidence suggests that lower testosterone may increase CKD risk in the general population and risk of all-cause mortality and CV events in men with CKD. Whether testosterone supplementation could prevent these potential detrimental outcomes should be determined in future intervention studies.

Background: There is no consensus regarding markers of optimal treatment or timing between glucocorticoid intake and assessment of hormone levels in the follow-up of female 21-hydroxylase deficient patients. Objective: To examine visit-to-visit repeatability in levels of adrenal hormones in adult female patients, to identify predictors of repeatability in hormone levels and to examine concordance between levels of different adrenal hormones. Method: All patients with confirmed 21-hydroxylase deficiency treated with glucocorticoids, were included. The two most recent blood samples collected on a stable dose of glucocorticoid replacement were compared. Complete concordance was defined as all measured adrenal hormones either within, below or above normal range evaluated in a single-day measurement. Results: Sixty-two patients, median age of 35 (range 18–74) years were included. All hormone levels showed moderate to excellent repeatability with an intraclass correlation coefficient between 0.80 and 0.99. Repeatability of hormone levels was not affected by the use of long-acting glucocorticoids or time of day for blood sample collection. The median difference in time between the two sample collections was 1.5 (range 0–7.5) h. Complete concordance between 17-hydroxyprogesterone, androstenedione, and testosterone was found in 21% of cases. Conclusion: During everyday, clinical practice hormone levels in adult female patients with 21-hydroxylase deficiency showed a moderate to excellent repeatability, despite considerable variation in time of day for blood sample collection. We found no major predictors of hormone level variation. Future studies are needed to address the relationship between the timing of glucocorticoid intake vs adrenal hormone levels and clinical outcome in both adults and children.

Catatonia is an abnormal psychological and behavioral state related to stress. The treatment strategy suggests the involvement of neuroactive steroids in its pathophysiology. We report a hospitalized patient with schizophrenia in whom a catatonic state occurred 7 times in 5.5 years. Blood levels of steroid hormones and adrenocorticotropic hormone (ACTH) were measured during the catatonic state and in the intervals between catatonic states (non-catatonic states). Cortisol and dehydroepiandrosterone sulfate (DHEAS) were significantly higher during catatonia than in the non-catatonic state. Cortisol significantly correlated with the ACTH level, whereas blood DHEAS and progesterone correlated only during the non-catatonic state. In addition, the cortisol to DHEAS ratios did not differ between catatonic and non-catatonic states. Although the correlating elevations of ACTH and cortisol implied activation of the hypothalamic-pituitary-adrenal axis (HPA-axis) in the catatonic state, DHEAS levels did not seem to increase in a manner dependent on the HPA-axis or the production of progesterone. The results suggest that the catatonic state was a neuroendocrinological state of HPA-axis activation with comparable increases in DHEAS levels. [ABSTRACT FROM AUTHOR]

Biochemical premature adrenarche is defined by elevated serum DHEAS [=40 µg/dL] before age 8 y in girls. This condition is receiving more attention due to its association with obesity, hyperinsulinemia, dyslipidemia, and polycystic ovary syndrome. Nevertheless, the link between early androgen excess and these risk factors remains unknown. Epigenetic modifications, and specifically DNA methylation, have been associated with the initiation and progression of numerous disorders, including obesity and insulin resistance. The aim of this study was to determine if prepubertal androgen exposure is associated with a different methylation profile in pubertal girls. Eighty-six healthy girls were studied. At age 7 y, anthropometric measurements were begun and DHEAS levels were determined. Girls were classified into Low DHEAS (LD) [<42 µg/dL] and High DHEAS (HD) [=42 µg/dL] groups. At Tanner stages 2 and 4 a DNA methylation microarray was performed to identify differentially methylated CpG positions (DMPs) between HD and LD groups. We observed a differential methylation pattern between pubertal girls with and without biochemical PA. Moreover, a set of DNA methylation markers, selected by the LASSO method, successfully distinguished between HD and LD girls regardless of Tanner stage. Additionally, a subset of these markers were significantly associated with glucose-related measures such as insulin level, HOMA-IR, and glycaemia. This pilot study provides evidence consistent with the hypothesis that high DHEAS concentration, or its hormonally active metabolites, may induce a unique blood methylation signature in pubertal girls, and that this methylation pattern is associated with altered glucose metabolism.

Alzheimer's Disease (AD) is a neurodegenerative disorder characterized by cognitive decline and memory loss. Recent studies have suggested a potential role for steroid synthesis in AD pathology. This study investigated the co-localization of steroidogenic enzymes in neuronal cells, changes in enzyme expression in an AD mouse model, and steroid expressions in human AD samples. Additionally, we conducted a steroidomic metabolomics analysis and evaluated the effects of dehydroepiandrosterone sulfate (DHEAS) treatment in an AD mouse model. Immunofluorescence analysis revealed significant co-localization of cytochrome P450 family 17 subfamily A member 1 (CYP17A1) and steroidogenic acute regulatory protein (StAR) proteins with α-synuclein in presynaptic neurons, suggesting active steroid synthesis in these cells. Conversely, such co-localization was absent in astrocytes. In the AD mouse model, a marked decrease in the expression of steroidogenic enzymes (Cyp11a1, Cyp17a1, Star) was observed, especially in areas with amyloid beta plaque accumulation. Human AD and MS brain tissues showed similar reductions in StAR and CYP17A1 expressions. Steroidomic analysis indicated a downregulation of key steroids in the serum of AD patients. DHEAS treatment in AD mice resulted in improved cognitive function and reduced Aβ accumulation. Our findings indicate a neuron-specific pathway for steroid synthesis, potentially playing a crucial role in AD pathology. The reduction in steroidogenic enzymes and key steroids in AD models and human samples suggests that impaired steroid synthesis is a feature of neurodegenerative diseases. The therapeutic potential of targeting steroid synthesis pathways, as indicated by the positive effects of DHEAS treatment, warrants further investigation. • CYP17A1 and StAR are predominantly expressed by neuronal cells in the normal brain. • Steroid synthesis is significantly reduced in Alzheimer's disease (AD). • Administration of DHEAS improves the behavioral status of AD mice.

Monitoring wildlife stress levels is essential to ensure their quality of life in captivity or in the wild. One promising method to assess the stress response is the comeasurement of glucocorticoids (GC) and dehydroepiandrosterone sulfate (DHEAS), adrenal hormones involved in the modulation of the stress response. Although noninvasive methods to measure GCs have been validated in several species, only a few studies have validated DHEAS assays. The aims of this study were (1) to describe an enzyme immunoassay (EIA) to measure DHEAS levels, (2) to validate this assay for fecal samples in gibbons and siamangs, and (3) to test hormonal stability after one freeze‐thaw cycle and over time at two freezer temperatures (−20°C and −80°C). Subjects included 32 gibbons and siamangs from U.S. zoological parks. The EIA was validated analytically by parallelism and accuracy tests, and biologically by confirming a DHEAS response 1–2 days after a stressful event (accident, vaccination, or transportation) in three individuals. In addition, fecal DHEAS levels in a pregnant female were above nonpregnant/nonlactating levels and declined progressively the following parturition. The hormonal stability experiments revealed no significant changes in fecal DHEAS levels after one freeze‐thaw cycle. Hormonal levels in fecal extracts were stable for 2 months, regardless of the storage temperature, with no significant differences between −20°C and −80°C conditions. The EIA described has high sensitivity and it is suitable for fecal DHEAS measurement in gibbons and siamangs, with a potential to be applied to other species. Research highlights: A new enzyme immunoassay was validated for gibbon and siamang feces.Dehydroepiandrosterone sulfate (DHEAS) levels in gibbons and siamang feces are stable after one freeze‐thaw cycle.DHEAS levels are stable in fecal extracts stored at −20°C for 2 months.

It is well known that a subgroup of women with PCOS present an excessive adrenal androgen production, generally associated with ovarian hyperandrogenism. In the past, it has been impossible to correlate adrenal hyperandrogenism to any clinical or hormonal pattern of PCOS. However, adrenal androgens are strictly dependent on age and their blood values reduce by 40% in patients moving from their twenties to thirties. Due to this, serum DHEAS values are strongly influenced by the age distribution of studied populations. To avoid this bias, in this study we retrospectively analyzed the clinical and hormonal data of PCOS women in their twenties (age between 20 and 29 years). Data of 648 young hyperandrogenic women with PCOS were evaluated. Serum DHEAS was increased in a third (33%) of studied patients and was associated with higher values of testosterone (T) and androstenedione (A). In each phenotype, patients with high DHEAS had higher values of T and A than patients with normal DHEAS of the same phenotype. Therefore, a DHEAS increase is generally part of a generalized higher androgen production in a subgroup of PCOS patients, independently of the finding of anovulatory or ovulatory cycles or of polycystic or normal ovaries. However, our study showed some important differences between PCOS phenotypes. A lower prevalence of increased DHEAS in A phenotype PCOS patients who generally have the highest androgen levels, versus non-classic (B or C) PCOS phenotypes, was observed. It was also found that patients with A phenotype PCOS present significantly lower BMI and serum insulin than patients with normal DHEAS of the same phenotype while, in patients with the B or C phenotype, the opposite occurs. We conclude that adrenal hyperandrogenism is more common in patients with non-classic (B and C) phenotypes of PCOS and is generally part of a generalized higher production of androgens in a subgroup of PCOS patients. However, other factors may increase the adrenal androgen production and influence the clinical expression of the syndrome. More studies in large, selected for age, populations of PCOS women with different phenotypes are needed. [ABSTRACT FROM AUTHOR]

Objective: Mental health has emerged as a worldwide concern given the increasing incidence of anxiety and depression disorders in the last years. Cortisol and sex steroid hormones have been demonstrated to be important regulators of mental health processes in older adults. However, the evidence considering these integrated variables in apparently healthy middle-aged individuals has not been thoroughly addressed. The present study aimed to investigate the association of the plasma cortisol, testosterone, free testosterone, sex hormone-binding globulin (SHBG), and dehydroepiandrosterone sulfate (DHEAS) levels with mental health in middle-aged adults., Methods: This cross-sectional study included a cohort of 73 middle-aged adults aged 45 to 65 years (women, 53%). Plasma cortisol, testosterone, SHBG, and DHEAS were assessed using a competitive chemiluminescence immunoassay. Free testosterone was calculated from the total testosterone and SHBG. Self-reported depression severity, generic health-related quality of life, hope, satisfaction with life, and optimism-pessimism were evaluated using the Beck Depression Inventory-II (BDI-II), 36-Item Short-Form Health Survey, Adult Hope Scale, Satisfaction with Life Scale, and Life Orientation Test-Revised, respectively-with higher total scores of these scales indicating greater levels of these variables., Results: The testosterone and free testosterone levels were inversely associated with the BDI-II values in men (all P ≤ .042). The cortisol levels were positively related with the Satisfaction with Life Scale scores, whereas the testosterone, free testosterone, SHBG, and DHEAS levels were negatively correlated with the BDI-II values in women (all P ≤ .045)., Conclusion: In summary, these results suggest that the increased levels of steroid hormones-within the normal values-are associated with better mental health in middle-aged adults., Competing Interests: Disclosure The authors have no conflicts of interest to disclose., (Copyright © 2024 AACE.

Objective: Anorexia nervosa (AN) is a serious condition characterized by undernutrition, complicated by endocrine dysregulation, and with few predictors of recovery. Urinary free cortisol (UFC) is a predictor of weight gain, but 24‐h urine samples are challenging to collect. We hypothesized that serum dehydroepiandrosterone sulfate (DHEAS), which like cortisol is regulated by adrenocorticotropic hormone (ACTH), would predict weight gain and increases in fat mass in women with AN. Methods: We prospectively studied 34 women with AN and atypical AN, mean age 27.4 ± 7.7 years (mean ± SD), who received placebo in a 6‐month randomized trial. Baseline DHEAS and 24‐h UFC were measured by liquid chromatography with tandem mass spectrometry. Body composition was assessed at baseline and 6 months by DXA and cross‐sectional abdominal CT at L4. Results: Mean baseline DHEAS level was 173 ± 70 μg/dl (0.7 ± 0.3 times the mean normal range for age) and mean baseline UFC (n = 15) was 20 ± 18 μg/24 h (normal: 0–50 μg/24 h). Higher DHEAS levels predicted weight gain over 6 months (r = 0.61, p <.001). DHEAS levels also predicted increases in fat mass (r = 0.40, p =.03), appendicular lean mass (r = 0.38, p =.04), and abdominal adipose tissue (r = 0.60, p <.001). All associations remained significant after controlling for age, baseline BMI, OCP use, duration of AN, and SSRI/SNRI use. DHEAS levels correlated with UFC (r = 0.61, p =.02). Discussion: In women with AN, higher serum DHEAS predicts weight gain and increases in fat and muscle mass. Additional studies are needed to confirm these findings and further elucidate the association between DHEAS and weight gain. Public Significance: Anorexia nervosa is a severe psychiatric condition, and predictors of weight recovery are needed to improve prognostication and guide therapeutic decision making. While urinary cortisol is a predictor of weight gain, 24‐h urine collections are challenging to obtain. Like cortisol, dehydroepiandrosterone sulfate (DHEAS) is a hormone produced by the adrenal glands. As a readily available blood test, DHEAS holds promise as more practical biomarker of weight gain in anorexia nervosa. [ABSTRACT FROM AUTHOR]

Background: The source of excess androgen can be obscure in postmenopausal women with new-onset hyperandrogenism. If serum dehydroepiandrosterone sulphate (DHEAS) is raised, it is presumed to be of adrenal origin because DHEAS is exclusively produced from adrenal cortical cells. This reports an elderly female presenting with new-onset hyperandrogenism due to an ovarian sex cord-stromal tumour, associated with increased serum DHEAS levels. Case description: A 76-year-old female with long-standing diabetes and hypertension presented with hirsutism and male type alopecia for six months. She had menopause at 55 years of age. There was a pelvic mass on examination. Total testosterone was 6.106 ng/ml (0.124–0.357) and DHEAS was > 1000 µg/dL (35–430). Contrast-enhanced computed tomography of the abdomen and pelvis showed a heterogeneously enhancing complex mass measuring 11 × 8 cm in the left adnexal region. Adrenal glands were normal. She underwent total abdominal hysterectomy, bilateral salphingo-oophorectomy, and omentectomy. Both testosterone and DHEAS normalised following surgery. Histology revealed a sex cord-stromal tumour, likely a steroid cell tumour with malignant potential. Fluorodeoxyglucose-Positron emission tomography did not show any additional lesions. Conclusions: Due to the lack of sulfotransferase in ovarian tissue, markedly elevated DHEAS originating from an ovarian neoplasm is unusual. This phenomenon has not been described except in a patient with a steroid cell tumour causing Cushing syndrome and hyperandrogenism. The mechanism of this rare occurrence remains elusive. Knowledge of this unusual presentation would enable the clinicians to be cautious in localising the androgen source in women with hyperandrogenism. [ABSTRACT FROM AUTHOR]

Introduction: Elevated cortisol levels have been reported in Alzheimer's disease (AD) and may accelerate the development of brain pathology and cognitive decline. Dehydroepiandrosterone sulfate (DHEAS) has anti-glucocorticoid effects and it may be involved in the AD pathophysiology. Objectives: To investigate associations of cerebrospinal fluid (CSF) cortisol and DHEAS levels with (1) cognitive performance at baseline; (2) CSF biomarkers of amyloid pathology (as assessed by CSF Ab levels), neuronal injury (as assessed by CSF tau), and tau hyperphosphorylation (as assessed by CSF p-tau); (3) regional brain volumes; and (4) clinical disease progression. Materials and Methods: Individuals between 49 and 88 years (n = 145) with mild cognitive impairment or dementia or with normal cognition were included. Clinical scores, AD biomarkers, brain MRI volumetry along with CSF cortisol and DHEAS were obtained at baseline. Cognitive and functional performance was re-assessed at 18 and 36 months from baseline. We also assessed the following covariates: apolipoprotein E (APOE) genotype, BMI, and education. We used linear regression and mixed models to address associations of interest. Results: Higher CSF cortisol was associated with poorer global cognitive performance and higher disease severity at baseline. Cortisol and cortisol/DHEAS ratio were positively associated with tau and p-tau CSF levels, and negatively associated with the amygdala and insula volumes at baseline. Higher CSF cortisol predicted more pronounced cognitive decline and clinical disease progression over 36 months. Higher CSF DHEAS predicted more pronounced disease progression over 36 months. Conclusion: Increased cortisol in the CNS is associated with tau pathology and neurodegeneration, and with decreased insula and amygdala volume. Both CSF cortisol and DHEAS levels predict faster clinical disease progression. These results have implications for the identification of patients at risk of rapid decline as well as for the development of interventions targeting both neurodegeneration and clinical manifestations of AD.

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 response. Limited evidence is available regarding the incidence and the effect of HPA dysfunction in COVID-19. Although the cortisol levels have only been estimated in a few studies, the dehydroepiandrosterone sulfate (DHEAS) release from the adrenal gland has not been explored yet. In this mini review, the authors discuss the role of dehydroepiandrosterone (DHEA) and DHEAS in the acute stress response and immunological modulation. Various effects of DHEAS have been demonstrated in different diseases. The specific inhibitory effect of DHEA on interleukin 6 (IL-6) could be of paramount importance in COVID-19. Further, DHEA supplementation has already been proposed in inflammatory conditions, like rheumatoid arthritis. DHEAS levels in COVID-19 may help to understand the HPA axis dysfunction as well as the possibility of repurposing DHEA as a drug for mitigating the pro-inflammatory COVID-19.

Résumé Contexte L’insuffisance en androgènes affecte les hommes à l’âge adulte, causant plusieurs effets nocifs aux niveaux reproductif et comportemental. Puisque l’aromatase est. une enzyme qui catalyse la conversion des androgènes en œstrogènes, et qu’elle est. responsable d’un équilibre adéquat des hormones sexuelles chez les hommes et les femmes, l’administration de molécules agissant comme freinateurs peut contribuer à restaurer une activité enzymatique anormale. Une étude prospective pilote a été menée pour étudier l’effet du D-chiro-inositol, un potentiel freinateur de l’aromatase, sur les taux sériques de testostérone, estradiol, estrone, déhydroépiandrostérone et d’épiandrostérone d’un groupe d’hommes adultes volontaires. Le glucose, l’insuline, l’hormone folliculostimulante, l’hormone lutéinisante, l’inhibine B, le D-chiro-inositol et les taux sériques de myo-inositol ont également été mesurés. Résultats Les hommes volontaires ont été sélectionnés selon l’âge et l’indice de masse corporelle. Les hommes qui présentaient une glycémie et/ou un statut hormonal altérés en raison d’un âge avancé ou d’un poids anormal, ont été inclus dans l’étude. Chacun des 10 volontaires enrôlés a pris du D-chiro-inositol (1 g/jour) par voie orale pendant un mois. Des dosages sériques des marqueurs sélectionnés ont été réalisés avant (témoin) et après le traitement. L’administration de D-chiro-inositol a été associée à une réduction des taux sériques de l’estrone (− 85.0%) et de l’estradiol (− 14,4%), et a une augmentation des taux sériques de testostérone (+ 23,4%) et de déhydroépiandrostérone (+ 13,8%). En outre, les taux d’épiandrostérone étaient plus élevés (39%) après le traitement. D’autre part, les taux d’hormone folliculostimulante, d’hormone lutéinisante et d’inhibine B n’ont pas été modifiés. Une tendance à la diminution de la glycémie, de l’insulinémie et de l’indice d’évaluation du modèle homéostatique a été observée après traitement par D-chiro-inositol, bien que les différences n’aient pas atteint une signification statistique. Le traitement par D-chiro-inositol n’a causé aucun effet indésirable notable. Conclusions L’augmentation des androgènes et la diminution des œstrogènes semblent confirmer que le D-chiro-inositol agit comme un freinateur de l’aromatase, mais avec un mécanisme d’action encore inconnu. Cette étude pilote ouvre de nouvelles perspectives de recherche et d’applications thérapeutiques pour le D-chiro-inositol à différents dosages et durées de traitement.

Abstract Background Hormones of the hypothalamic–pituitary–gonadal (HPG), hypothalamic–pituitary–adrenal (HPA), and hypothalamic–pituitary–somatotropic (HPS) axes are potentially involved in major depressive disorder (MDD), but these hormones have not been simultaneously investigated in male patients with MDD. We investigated the association between male MDD symptoms and estradiol, testosterone, cortisol, dehydroepiandrosterone sulfate (DHEAS), and insulin-like growth factor 1 (IGF1). Methods Serum estradiol, testosterone, cortisol, DHEAS, and IGF1 levels were measured in 54 male patients with MDD and 37 male controls and were compared with clinical factors. We investigated the associations between hormone levels and Hamilton Depression Rating Scale (HAM-D) scores. The correlations among hormones were also investigated. Results Patients had significantly lower estradiol levels than controls (22.4 ± 8.4 pg/mL vs. 26.1 ± 8.5 pg/mL, P = 0.040). Serum estradiol levels were negatively correlated with HAM-D scores (P = 0.000094) and positively correlated with Global Assessment of Functioning scores (P = 0.000299). IGF1 levels and the cortisol:DHEAS ratio were higher in patients than in controls (IGF1: 171.5 ± 61.8 ng/mL vs. 144.1 ± 39.2 ng/mL, P = 0.011; cortisol:DHEAS ratio: 0.07 ± 0.05 vs. 0.04 ± 0.02, P = 0.001). DHEAS levels were lower in patients than in controls (227.9 ± 108.4 μg/dL vs. 307.4 ± 131.2 μg/dL, P = 0.002). IGF1, cortisol:DHEAS ratio, and DHEAS were not significantly correlated with HAM-D scores. Cortisol and testosterone levels were not significantly different between patients and controls. Serum estradiol levels were positively correlated with DHEAS levels (P = 0.00062) in patients, but were not significantly correlated with DHEAS levels in controls. Conclusion Estradiol may affect the pathogenesis and severity of patients with MDD in men, and other hormones, such as those in the HPA and HPS axes, may also be involved in male MDD. Additionally, a correlation between estradiol and DHEAS may affect the pathology of MDD in men.

The benefits of treatment with testosterone (T) in women with loss of desire suggest that low androgens may distinguish women with sexual dysfunction (SD) from others; however, evidence on this point is lacking. To answer the question: is there an association between endogenous levels of androgens and sexual function in women? An extensive search was performed in MEDLINE, Embase and PsycInfo. Four separate meta-analyses were conducted for total T, free T, Free Androgen Index (FAI), and Dehydroepiandrosterone sulphate (DHEAS). Cohort, cross-sectional, and prospective studies were included. The main outcome was the association between endogenous androgens and sexual desire. Global sexual function was considered as a secondary outcome. The effect measure was expressed as standardized mean difference (SMD). The meta-analysis on total T included 34 studies involving 3,268 women, mean age 36.5 years. In 11 studies, a significant association was found between sexual desire, measured by validated psychometric instruments, and total T (SMD = 0.59 [0.29;0.88], P < 0.0001), with a moderate effect. The association with global sexual function (n = 12 studies) was also significant (SMD = 0.44 [0.21;0.67], P <0.0001). Overall, total T was associated with a better sexual function (SMD = 0.55 [0.28;0.82)], P < 0.0001), with similar results obtained when poor quality studies were removed. Age showed a negative relationship with the overall outcome. No differences were found when stratifying the studies according to menopausal status, type of menopause, age at menopause, use of hormonal replacement therapy, relationship status, method for T measurement, phase of the menstrual cycle or use of hormonal contraception. The meta-analysis of T derivatives (free T and FAI) also showed a significant, moderate association with sexual desire. In contrast, DHEAS seems not to exert any significant influence on desire, whilst showing a positive association with global sexual function. Endogenous androgens show a moderate association with a better sexual function in women; however, the role of psychological, relational and other hormonal factors should not be overlooked. This represents the first attempt at meta-analyzing data available on the topic. A significant publication bias was found for total T. There appears to be a moderate association between total T and sexual desire/global sexual function, which is confirmed, although weak, in studies employing liquid chromatography-mass spectrometry (LC-MS). Similar results on desire were obtained for free T and FAI. DHEAS only showed a positive association with global sexual function. More research is needed. Maseroli E and Vignozzi L.

Context: Adrenarche reflects the developmental growth of the adrenal zona reticularis, which produces increasing adrenal androgen secretion (eg, dehydroepiandrosterone [DHEA]/dehydroepiandrosterone sulfate [DHEAS]) from approximately age 5 to 15 years. Objective: We hypothesized that the study of the genetic determinants associated with variations in serum DHEAS during adrenarche might detect genetic variants influencing the rate or timing of this process. Methods: Genome-wide genotyping was performed in participants of the Chilean pediatric Growth and Obesity Chilean Cohort Study (GOCS) cohort (n = 788). We evaluated the genetic determinants of DHEAS levels at the genome-wide level and in targeted genes associated with steroidogenesis. To corroborate our findings, we evaluated a polygenic risk score (PRS) for age at pubarche, based on the discovered variants, in children from the same cohort. Results: We identified one significant variant at the genome-wide level in the full cohort, close to the GALR1 gene (P = 3.81 × 10–8). In addition, variants suggestive of association (P < 1 × 10–5) were observed in PRLR, PITX1, PTPRD, NR1H4, and BCL11B. Stratifying by sex, we found variants suggestive of association in SERBP1 and CAMTA1/VAMP3 for boys and near ZNF98, TRPC6, and SULT2A1 for girls. We also found significant reductions in age at pubarche in those children with higher PRS for greater DHEAS based on these newly identified variants. Conclusion: Our results disclose one variant associated with DHEAS concentrations at the level of genome-wide association study significance, and several variants with a suggestive association that may be involved in the genetic regulation of adrenarche.

Objective: Adaptive changes in DHEA and sulfated-DHEA (DHEAS) production from adrenal zona reticularis (ZR) have been observed in normal and pathological conditions. Here we used three different cohorts to assess timing differences in DHEAS blood level changes and characterize the relationship between early blood DHEAS reduction and cell number changes in women ZR. Materials and methods: DHEAS plasma samples (n = 463) were analyzed in 166 healthy prepubertal girls before pubarche (35% of the females >40 years old and associated with significantly reduced ZR cell number (ba sed on PTEN and hematoxylin signals). ZR cell loss may in part account for lower DHEA/DHEAS expression, but most cells remain alive with lower DHEA/DHEAS biosynthesis. Conclusion: The timely relation between significant reduction of blood DHEAS levels and decreased ZR cell number at the beginning of the 40s suggests that adrenopause is an additional burden for a significant number of middle-aged women, and may become an emergent problem associated with further sex steroids reduction during the menopausal transition.

In addition to the endocrine and paracrine systems, peripheral tissues such as gonads, skin, and adipose tissue are involved in the intracrine mechanisms responsible for the formation of sex steroids via the transformation of dehydroepiandrosterone and dehydroepiandrosterone sulfate (DHEA/DHEAS) into potent androgenic and estrogenic hormones. Numerous studies have examined the relationship between overweight, central obesity, and plasma levels of DHEA and DHEAS. The sodium-dependent organic anion transporter Soat (Slc10a6) is a plasma membrane uptake transporter for sulfated steroids. Significantly increased expression of Slc10a6 mRNA has been previously described in organs and tissues of lipopolysaccharide (LPS)-treated mice, including white adipose tissue. These findings suggest that Soat plays a role in the supply of steroids in peripheral target tissues. The present study aimed to investigate the expression of Soat in adipocytes and its role in adipogenesis. Soat expression was analyzed in mouse white intra-abdominal (WAT), subcutaneous (SAT), and brown (BAT) adipose tissue samples and in murine 3T3-L1 adipocytes. In addition, adipose tissue mass and size of the adipocytes were analyzed in wild-type and Slc10a6−/− knockout mice. Soat expression was detected in mouse WAT, SAT, and BAT using immunofluorescence. The expression of Slc10a6 mRNA was significantly higher in 3T3-L1 adipocytes than that of preadipocytes and was significantly upregulated by exposure to lipopolysaccharide (LPS). Slc10a6 mRNA levels were also upregulated in the adipose tissue of LPS-treated mice. In Slc10a6−/− knockout mice, adipocytes increased in size in the WAT and SAT of female mice and in the BAT of male mice, suggesting adipocyte hypertrophy. The serum levels of adiponectin, resistin, and leptin were comparable in wild-type and Slc10a6−/− knockout mice. The treatment of 3T3-L1 adipocytes with DHEA significantly reduced lipid accumulation, while DHEAS did not have a significant effect. However, following LPS-induced Soat upregulation, DHEAS also significantly inhibited lipid accumulation in adipocytes. In conclusion, Soat-mediated import of DHEAS and other sulfated steroids could contribute to the complex pathways of sex steroid intracrinology in adipose tissues. Although in cell cultures the Soat-mediated uptake of DHEAS appears to reduce lipid accumulation, in Slc10a6−/− knockout mice, the Soat deletion induced adipocyte hyperplasia through hitherto unknown mechanisms.

Background: Iatrogenic adrenal insufficiency (AI) secondary to long‐term treatment with exogenous glucocorticoids (GC) is common in patients with systematic rheumatic diseases, including rheumatoid arthritis (RA). Moreover, a proportion of these patients is always in need of even small doses of glucocorticoids to maintain clinical remission, despite concomitant treatment with conventional and biologic disease‐modifying drugs. Methods: We conducted a literature review up to December 2020 on (a) the incidence of AI in both long‐term GC‐treated and GC‐treatment naïve RA patients; (b) the potential effects of increased levels of circulating proinflammatory cytokines, as well as of chronic stress, in adrenocortical function in RA; (c) the circadian cortisol rhythm in RA; and (d) established and evolving methods of assessment of adrenocortical function. Results: Up to 48% of RA patients develop glucocorticoid‐induced AI; however, predictors are not established, while adrenocortical dysfunction may also occur in GC‐treatment naïve RA patients. Experimental and clinical data have suggested that inadequate production of endogenous cortisol relative to enhanced clinical needs associated with the systemic inflammatory response, coined as the 'disproportion principle', may operate in RA. Although the underlying mechanisms are unknown, both proinflammatory cytokines and chronic stress may contribute the most in the adrenals hyporesponsiveness and the target tissue glucocorticoid resistance that have been described, but not systematically studied. A precise longitudinal assessment of endogenous cortisol production may be needed for optimal RA management. Conclusion: Apart from iatrogenic AI, an intrinsically compromised adrenal reserve in RA may have a pathogenetic role and interfere with effective management, thus deserving further research.

Context: The adrenal cortex produces specific steroid hormones including steroid sulfates such as dehydroepiandrosterone sulfate (DHEAS), the most abundant steroid hormone in the human circulation. Steroid sulfation involves a multistep enzyme machinery that may be impaired by inborn errors of steroid metabolism. Emerging data suggest a role of steroid sulfates in the pathophysiology of adrenal tumors and as potential biomarkers.Evidence Acquisition: Selective literature search using "steroid," "sulfat*," "adrenal," "transport," "mass spectrometry" and related terms in different combinations.Evidence Synthesis: A recent study highlighted the tissue abundance of estrogen sulfates to be of prognostic impact in adrenocortical carcinoma tissue samples using matrix-assisted laser desorption ionization mass spectrometry imaging. General mechanisms of sulfate uptake, activation, and transfer to substrate steroids are reasonably well understood. Key aspects of this pathway, however, have not been investigated in detail in the adrenal; these include the regulation of substrate specificity and the secretion of sulfated steroids. Both for the adrenal and targeted peripheral tissues, steroid sulfates may have relevant biological actions beyond their cognate nuclear receptors after desulfation. Impaired steroid sulfation such as low DHEAS in Cushing adenomas is of diagnostic utility, but more comprehensive studies are lacking. In bioanalytics, the requirement of deconjugation for gas-chromatography/mass-spectrometry has precluded the study of steroid sulfates for a long time. This limitation may be overcome by liquid chromatography/tandem mass spectrometry.Conclusions: A role of steroid sulfation in the pathophysiology of adrenal tumors has been suggested and a diagnostic utility of steroid sulfates as biomarkers is likely. Recent analytical developments may target sulfated steroids specifically. [ABSTRACT FROM AUTHOR]

Objective: Autonomous cortisol secretion (ACS) is a condition with ACTH-independent cortisol overproduction from adrenal incidentalomas (AI) or adrenal hyperplasia. The hypercortisolism is often mild, and most patients lack typical clinical features of overt Cushing’s syndrome (CS). ACS is not well defined and diagnostic tests lack validation. Methods: Retrospective study of 165 patients with AI evaluated clinically and by assay of morning plasma ACTH, late-night saliva cortisol, serum DHEA sulphate (DHEAS), 24-h urine-free cortisol, and cortisol after dexamethasone suppression. Results: Patients with AI (n = 165) were diagnosed as non-functioning incidentalomas (NFI) (n = 82) or ACS (n = 83) according to current European guidelines. Late-night saliv a cortisol discriminated poorly between NFI and ACS, showing a high rate of false-positive (23/63) and false-negative (38/69) results. The conventional lo w-dose dexamethasone suppression test (LDDST) did not improve the diagnostic specific ity, compared with the 1 mg overnight DST. Receiver operating characteristic curve analysis of DHEAS in the two cohorts demonstrated an area under the curve of 0.76 (P < 0.01) with a sensitivity for ACS of 58% and a specificity of 80% using the recommended cutoff at 1.04 μmol/L (40 μg/dL). Conclusion: We here demonstrate in a large retrospective cohort of incidentaloma patients, that neither DHEAS, late-night saliva cortisol nor 24-h urine free cortisol are useful to discriminate between non-functioning adrenal incidentalomas and ACS. The conventional LDDST do not add further information compared with the 1 mg ove rnight DST. Alternative biomarkers are needed to improve the diagnostic workup of ACS.

However, the clinical significance of DHEA and DHEAS concentrations in patients with NSCLC receiving chemotherapy (CT) has not been sufficiently documented.Objective: To evaluate the correlation between mental health and hormone concentrations on patients with advanced non-small-cell lung cancer (NSCLC).Materials and Methods: The present study was a cross-sectional analysis based on a self-reported psychological investigation. Salivary samples were collected from 22 patients with advanced NSCLC after CT and 17 healthy controls. The concentrations of DHEA, DHEAS, and cortisol were analyzed to investigate their associations with the results of self-reported questionnaires on psychological health.Results: Patients with advanced NSCLC exhibited significantly higher Patient Health Questionnaire (PHQ-9) and Startle, Physiological arousal, Anger, and Numbness-Chinese version (SPAN-C) scores, poorer health conditions, lower sleep quality, and more severe fatigue after CT than did healthy controls, and salivary concentrations of DHEA and DHEAS were significantly lower among patients after CT than among controls. DHEAS concentrations were negatively associated with depression scores (PHQ-9, r = − 0.496, P = 0.019) and fatigue scores (Brief Fatigue Inventory-Taiwan, r = − 0.562, P = 0.006).Conclusion: Patients with advanced NSCLC after CT had lower DHEA and DHEAS concentrations than did controls. Lower DHEAS concentrations were associated with higher fatigue and depression scores.Keywords: cancer-related fatigue, chemotherapy, DHEA, DHEAS, lung cancer

Androgen assessment is a key element for diagnosing polycystic ovary syndrome (PCOS), and defining a “normal” level of circulating androgens is critical for epidemiological studies. We determined the upper normal limits (UNLs) for androgens in a population-based group of premenopausal “healthy control” women, overall and by ethnicity (Caucasian and Asian), in the cross-sectional Eastern Siberia PCOS Epidemiology and Phenotype (ESPEP) Study (ClinicalTrials.gov ID: NCT05194384) conducted in 2016–2019. Overall, we identified a “healthy control” group consisting of 143 healthy premenopausal women without menstrual dysfunction, hirsutism, polycystic ovaries, or medical disorders. We analyzed serum total testosterone (TT) by using liquid chromatography with tandem mass spectrometry (LC-MS/MS), and DHEAS, sex-hormone-binding globulin (SHBG), TSH, prolactin, and 17-hydroxyprogesterone (17OHP) were assessed with an enzyme-linked immunosorbent assay (ELISA). The UNLs for the entire population for the TT, free androgen index (FAI), and DHEAS were determined as the 98th percentiles in healthy controls as follows: 67.3 (95% confidence interval (CI): 48.1, 76.5) ng/dl, 5.4 (3.5, 14.0), and 355 (289, 371) μg/dl, respectively. The study results demonstrated that the UNLs for TT and FAI varied by ethnicity, whereas the DHEAS UNLs were comparable in the ethnicities studied.

It is well known that a subgroup of women with PCOS present an excessive adrenal androgen production, generally associated with ovarian hyperandrogenism. In the past, it has been impossible to correlate adrenal hyperandrogenism to any clinical or hormonal pattern of PCOS. However, adrenal androgens are strictly dependent on age and their blood values reduce by 40% in patients moving from their twenties to thirties. Due to this, serum DHEAS values are strongly influenced by the age distribution of studied populations. To avoid this bias, in this study we retrospectively analyzed the clinical and hormonal data of PCOS women in their twenties (age between 20 and 29 years). Data of 648 young hyperandrogenic women with PCOS were evaluated. Serum DHEAS was increased in a third (33%) of studied patients and was associated with higher values of testosterone (T) and androstenedione (A). In each phenotype, patients with high DHEAS had higher values of T and A than patients with normal DHEAS of the same phenotype. Therefore, a DHEAS increase is generally part of a generalized higher androgen production in a subgroup of PCOS patients, independently of the finding of anovulatory or ovulatory cycles or of polycystic or normal ovaries. However, our study showed some important differences between PCOS phenotypes. A lower prevalence of increased DHEAS in A phenotype PCOS patients who generally have the highest androgen levels, versus non-classic (B or C) PCOS phenotypes, was observed. It was also found that patients with A phenotype PCOS present significantly lower BMI and serum insulin than patients with normal DHEAS of the same phenotype while, in patients with the B or C phenotype, the opposite occurs. We conclude that adrenal hyperandrogenism is more common in patients with non-classic (B and C) phenotypes of PCOS and is generally part of a generalized higher production of androgens in a subgroup of PCOS patients. However, other factors may increase the adrenal androgen production and influence the clinical expression of the syndrome. More studies in large, selected for age, populations of PCOS women with different phenotypes are needed.

The majority of incidentally discovered adrenal tumors are later characterized as non-producing adrenocortical adenomas (NPA). We asked whether laboratory abnormalities in parameters that reflect glucocorticoid action can be found in patients with NPA despite their nature of being clinically unapparent. Since glucocorticoids are potent immunosuppressants we studied blood counts and differential blood counts along with corticotropin and dehydroepiandrostenedione sulfate (DHEAS) blood concentrations, as well as cortisol values before and after an overnight 1 mg dexamethasone suppression test. We compared the results of normal individuals, of patients with adrenal adenomas and normal hormone profiles and with subclinical autonomous glucocorticoid hypersecretion, as well as overt cortisol excess. We found that almost all indices of the blood counts were significantly different between the patients groups. In particular, patients with adrenal non-producing adenomas already showed signs of glucocorticoid excess, including relative lymphocytopenia, lowered DHEAS, and ACTH concentrations than control individuals. We also found that the extent of lymphocytopenia correlated with the concentrations of DHEAS and ACTH, and DHEAS correlated well with ACTH. We conclude that the basal ACTH and DHEAS values along with the differential blood counts give good information on the extent of glucocorticoid excess and that silent adrenal adenomas seem to oversecrete glucocorticoids at concentrations that already alter these parameters.

Neurosteroids have been identified in the 1981. Dehydroepiandrosterone sulphate (DHEAS) is one of the vital neurosteroids that de novo synthesized in the nervous system from cholesterol precursor (Baulieu & Robel, 1998). The aim of the study is to develop a method for fluorescence labelling. Alexa Fluor 488 dye with DHEAS antibody can binds the DHEAS antibody in the rat brain monitored by Cellvizio Lab System. DHEAS antibody (IgG isotype antibodies) was fluorescently conjugated by an amine-reactive compound, Alexa Fluor 5-SDP ester 488 dye. The resultant Alexa Fluor 488-conjugated antibodies were collected and analyzed by UV-Vis spectrophotometer instrument. The absorbance of the protein-dye conjugate at 280 nm and 494 nm were measured. Then, the degree of labeling (DOL) was calculated to achieve the desired results. Fluorescence labelling were carried out into the CA1 region of hippocampus Sprague-Dawley rat. We reported that the conjugation was successful. Optimal labeling depending on degree of labeling (DOL) needs some necessity to achieve and effective binding to the target neurosteroid, DHEAS. Cellvizio Lab system connected with Fiber Fluorescence Microscopy (FFM) probe is presented as a new approach in real-time imaging of DHEAS. In conclusion, we have developed a new method of DHEAS-Alexa Fluor fluorescence labelling to visualize and evaluate the changes of DHEAS fluorescence level in the rat hippocampus. This novel approach as a diagnostic tool and can be used to better understand the mechanisms and functions of DHEAS and other neurosteroids in future research.

Background: Reduced total hours of sleep and low quality of sleep have been suggested to be associated with low levels of male hormones. Few studies have examined the association between excessive sleep and male reproductive hormones. Objective: To investigate the association of total hours of sleep and quality of sleep with serum levels of total, bioavailable and free testosterone (tT, bT and fT), sex hormone-binding globulin (SHBG) and dehydroepiandrosteron-sulfate (DHEAS). Methods: Serum levels of tT, SHBG and DHEAS were measured with immunoassays in a cross-sectional population-based study of 2095 males. bT and fT were calculated in accordance with Vermeulens method. Information on total hours of sleep and sleep quality was obtained by questionnaire. Linear regression was used to calculate hormones according to total hours of sleep and the results were expressed as β-estimates and 95% confidence intervals (CI). The adjustment in the multivariable models was constructed taking age, BMI, smoking, alcohol intake and physical activity into account. Results: Excessive sleep (>9 h) compared to 7–9 h of sleep was significantly associated with lower tT, bT and fT, but not with SHBG or DHEAS, after multivariable adjustment. These significant associations were also found in our analyses with hormones as continuous variables but no associations were found in our general additive model analyses. Conclusions: In this cross-sectional study in men, excessive sleep associated with lower levels of male reproductive hormones. Longitudinal studies are needed to determine the causal direction of the observed association between excessive sleep and lower male reproductive hormones levels.

Abstract Background Data on adrenarche and pubarche in girls with Turner syndrome (TS) are inconsistent in the literature. Methods The cohort consisted of 94 girls and young women with TS born between 1971 and 2001 (age range: 3.1–23.2 yrs.), who were treated with human growth hormone and regularly presented at our outpatient clinic every 4 to 6 months.The longitudinal data of all patients were ascertained retrospectively from patient charts. The data collection ended in January 2016. Adrenarche was assessed by serum DHEAS levels and pubertal status by Tanner stages. Pubarche was defined as the appearance of pubic hair (PH2), whereas spontaneous puberty was defined as Tanner stage B2. The patients were retrospectively subdivided in two groups with regard to pubertal development: group 1 (n = 21) with spontaneous puberty and group 2 (n = 70) with induced puberty. Since blood samples were not taken at every visit, we generated seven groups according to the age of the children at which the blood samples were taken: 3–5, 5–7, 7–9, 9–11, 11–13, 13–15, and 15–17 yrs. Serum DHEAS and follicle-stimulating hormone (FSH) levels were measured by chemiluminescence immunoassay and compared with those of a control group of healthy girls. Results Adrenarche started in TS girls between 5 and 7 years. TS girls had higher DHEAS levels than the control group, with statistically significant differences in the age groups 7 to 17 years. No differences were determined between the TS girls with spontaneous puberty and those with POI. TS girls in group 2 reached the Tanner stages PH2 (p

In this study, waste fat from the Chinese soft-shelled turtle (Pelodiscus sinensis) was used as the raw material, and soft-shelled turtle oil (SSTO) was extracted by water heating. Analysis of the fatty acid composition of SSTO revealed that unsaturated fatty acids (UFAs) comprised more than 70% of the oil, of which more than 20% were omega-3 poly-UFAs. DPPH radical scavenging and cellular ROS assays confirmed the reduction of oxidative stress by SSTO. In D-galactose-induced aging rats, SSTO feeding alone or in combination with swimming training resulted in improved memory and physical strength. In addition, SSTO feeding with swimming intervention significantly increased the SOD level and maintained better blood pressure in the aged rats. The serum DHEAS and soleus muscle glycogen level were also highly correlated with SSTO feeding and swimming training. In conclusion, the results of this study demonstrated that SSTO has the potential to be developed into a health food that exerts anti-aging effects, and those effects are stronger when combined with daily swimming exercise.

Background: Hormones of the hypothalamic–pituitary–gonadal (HPG), hypothalamic–pituitary–adrenal (HPA), and hypothalamic–pituitary–somatotropic (HPS) axes are potentially involved in major depressive disorder (MDD), but these hormones have not been simultaneously investigated in male patients with MDD. We investigated the association between male MDD symptoms and estradiol, testosterone, cortisol, dehydroepiandrosterone sulfate (DHEAS), and insulin-like growth factor 1 (IGF1). Methods: Serum estradiol, testosterone, cortisol, DHEAS, and IGF1 levels were measured in 54 male patients with MDD and 37 male controls and were compared with clinical factors. We investigated the associations between hormone levels and Hamilton Depression Rating Scale (HAM-D) scores. The correlations among hormones were also investigated. Results: Patients had significantly lower estradiol levels than controls (22.4 ± 8.4 pg/mL vs. 26.1 ± 8.5 pg/mL, P = 0.040). Serum estradiol levels were negatively correlated with HAM-D scores (P = 0.000094) and positively correlated with Global Assessment of Functioning scores (P = 0.000299). IGF1 levels and the cortisol:DHEAS ratio were higher in patients than in controls (IGF1: 171.5 ± 61.8 ng/mL vs. 144.1 ± 39.2 ng/mL, P = 0.011; cortisol:DHEAS ratio: 0.07 ± 0.05 vs. 0.04 ± 0.02, P = 0.001). DHEAS levels were lower in patients than in controls (227.9 ± 108.4 μg/dL vs. 307.4 ± 131.2 μg/dL, P = 0.002). IGF1, cortisol:DHEAS ratio, and DHEAS were not significantly correlated with HAM-D scores. Cortisol and testosterone levels were not significantly different between patients and controls. Serum estradiol levels were positively correlated with DHEAS levels (P = 0.00062) in patients, but were not significantly correlated with DHEAS levels in controls. Conclusion: Estradiol may affect the pathogenesis and severity of patients with MDD in men, and other hormones, such as those in the HPA and HPS axes, may also be involved in male MDD. Additionally, a correlation between estradiol and DHEAS may affect the pathology of MDD in men. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to evaluate the effect of dutasteride treatment of benign prostatic hyperplasia on serum steroidal sex hormones and prostate volume (PV). Methods: Thirty patients with benign prostate hyperplasia treated with dutasteride for one year were assessed for changes in PV and serum sex hormones (testosterone (T), dihydotestosterone (DHT), estradiol (E2) and dehydroepiandrosterone sulphate (DHEAS)). PV was measured by ultrasonography. A paired or unpaired t -test and Pearson's correlation coefficient test were used for statistical analysis. Results: DHT and DHEAS decreased by 38.5% and 20.3%, respectively. On the contrary, T and E2 increased by 34.3% and 9.4%, respectively. PV and prostate-specific antigen decreased by 17.7% and 63.4%, respectively. The rate of decrease of DHT had a negative correlation with PV, and the rate of decrease of DHEAS had positive correlation with PV. Conclusion: DHT did not decrease as expected (previous studies showed a decrease of approximately 90%). However, DHEAS decreased more than a natural decrease. It is possible that the conversion from DHEAS to DHT, via the conversion to T, in the prostate was accelerated by the decrease of DHT, especially in larger prostates. However, this discrepancy cannot be full explained by the conversion from DHEAS to DHT, as mentioned above. Level of evidence: Level 2c [ABSTRACT FROM AUTHOR]
