RESUMO

Human fetal cytochrome P450 3A7 (CYP3A7) is involved in both xenobiotic metabolism and the estriol biosynthetic pathway. Although much is understood about cytochrome P450 3A4 and its role in adult drug metabolism, CYP3A7 is poorly characterized in terms of its interactions with both categories of substrates. Herein, a crystallizable mutated form of CYP3A7 was saturated with its primary endogenous substrate dehydroepiandrosterone 3-sulfate (DHEA-S) to yield a 2.6 Å X-ray structure revealing the unexpected capacity to simultaneously bind four copies of DHEA-S. Two DHEA-S molecules are located in the active site proper, one in a ligand access channel, and one on the hydrophobic F'-G' surface normally embedded in the membrane. While neither DHEA-S binding nor metabolism exhibit cooperative kinetics, the current structure is consistent with cooperativity common to CYP3A enzymes. Overall, this information suggests that mechanism(s) of CYP3A7 interactions with steroidal substrates are complex.

RESUMO

BACKGROUND: Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder associated with infertility and pregnancy complications. The pathogenesis of PCOS and its impact on reproductive function may be influenced by the source of androgens, including testosterone, free androgen, dehydroepiandrosterone sulfate (DHEAS). However, the differential effects of these androgen on pregnancy and neonatal outcomes and the cut-off value of East Asian population with PCOS remain unclear. METHODS: A retrospective cohort study was conducted at the Reproductive Medicine Center of the First Affiliated Hospital of Sun Yat-sen University from January 2015 to November 2022, involving 636 cycles of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). Subgroup analyses were performed using cut-off values of 6.4 for free androgen index (FAI), 9.5 µmol/L for DHEAS. Pregnancy and neonatal outcomes were compared between groups. Restricted cubic spline (RCS) was used to identify significant cut-off values affecting pregnancy. RESULTS: Higher FAI levels (> 6.4) were associated with decrease in clinical pregnancy rate (PR) (50.61% vs. 41.66%, p = 0.024), live birth rate (LBR) (42.42% vs. 32.35%, p = 0.011). When DHEAS levels exceeded 9.5 µmol/L, there was a significant decrease in clinical PR (51.27% vs. 42.73%, P = 0.039), LBR (42.73% vs. 32.73%, P = 0.012). Negative correlations were also observed between DHEAS levels and cumulative pregnancy rate (70.57% vs 56.62% p = 0.002) and cumulative live birth rate (CLBR) (59.35% vs 43.37%, p = 0.0007). Both FAI and DHEAS elevated is associated with the lowest clinical pregnancy rate (37.84%). Conversely, when solely FAI is elevated, the pregnancy rate increases to 52.38%, while an elevation in DHEAS alone is associated with a pregnancy rate of, both of which are lower than when neither FAI nor DHEAS are elevated (60.68%). The live birth rates exhibit a similar trend (30.00% vs 40.00% vs 41.83% vs 44.48%). RCS revealed a significant decrease in CPR and CLBR when DHEA levels exceeded 7.69 umol/L, while the cut-off value of FAI was 6.36 for CPR and CLBR. CONCLUSION: In conclusion, PCOS patients with biochemical hyperandrogenism show unsatisfactory clinical PR and CLBR when undergoing assisted reproductive technology (ART). This may be attributed to the influence of both adrenal-derived DHEAS and ovarian-derived FAI on the unfavorable pregnancy outcomes.

RESUMO

Prenatal exposure to inflammation is related to the risk for cognitive impairment in offspring. However, mechanisms underlying the link between inflammatory cytokines at the maternal-fetal interface and human cognitive development are largely unknown. This study addressed this research gap by examining whether i) cytokines within the placenta are associated with different domains of neurocognitive development during infancy, and ii) if DHEA-S in cord blood mediates these associations. We also explored the role of early-life socioeconomic status (SES) in moderating the effect of fetal adrenal steroids on cognitive development in low- and middle-income country contexts. A cohort of 242 mother-infant dyads in Leyte, the Philippines participated in the study and all of them were followed from early pregnancy until 12-months. Concentrations of pro- and anti-inflammatory cytokines in the placenta, and DHEA-S in cord blood collected at delivery were evaluated. The multifactorial aspects of the infant's cognitive functioning were assessed based on the Bayley Scales of Infant Development, third edition (BSID-III). We used Structural Equation Modelling (SEM) with an orthogonal rotation to examine associated paths among latent variables of pro- and anti-inflammatory cytokines in the placenta, fetal neuroendocrine factors, and cognitive development. Pathway analyses showed that both pro- and anti-inflammatory cytokines in the placenta were indirectly related to cognitive (p < 0.05) and language developmental outcomes (p < 0.1) via DHEA-S in cord blood among the low SES group. Yet, we found no statistically significant indirect effect of pro- or anti-inflammatory cytokines on neurocognitive development among the high SES sub-sample. This study extends our understanding of how early-life socioeconomic conditions modify biological pathways underlying the relationship between prenatal factors and postpartum cognitive development.

RESUMO

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.

RESUMO

PURPOSE: To evaluate the initial impact of a combined oral contraceptive (COC) containing norgestimate (NGM) on female sexuality and on circulating androgen levels in users. MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

RESUMO

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 (ß = .05, p = .003) and androstenedione (ß = .03, p = .02) were independently associated with a higher risk of SiMS score, while higher DHEAS levels were associated with a lower siMS score (ß = -.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.

RESUMO

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.

RESUMO

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.

RESUMO

We and other research groups have previously described that levels of the anabolic hormone dehydroepiandrosterone sulfate (DHEA-S) are lowered in individuals who report prolonged stress. We have also shown that the DHEA-S production capacity during acute stress is attenuated in individuals reporting high prolonged stress. This study aimed to further investigate the DHEA and DHEA-S production capacity in relation to prolonged stress. Eighty-one healthy participants in the age 20-50 years old were included in the study and divided into a low stress (n = 45) and a high stress group (n = 36) according their response to a single question regarding perceived stress during the preceding month. They underwent the Trier Social Stress Test while blood samples were drawn before, during and after the stress test. The concentration of DHEA, DHEA-S, cortisol and ACTH was measured. The results showed that the high stress group exhibited a significantly lower response of DHEA-S (40% lower) than the low stress group, while DHEA, cortisol and ACTH responses did not differ between the groups. Reduced DHEA-S production may constitute one of the links between stress and poor health.

RESUMO

BACKGROUND: 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. AIM: To answer the question: is there an association between endogenous levels of androgens and sexual function in women? METHODS: 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. OUTCOMES: 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). RESULTS: 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. CLINICAL IMPLICATIONS: 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. STRENGTHS & LIMITATIONS: This represents the first attempt at meta-analyzing data available on the topic. A significant publication bias was found for total T. CONCLUSION: 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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

In a parallel placebo-controlled study, we examined the effect of repetitive transcranial magnetic stimulation (rTMS) on serum concentrations of cortisol and dehydroepiandrosteron sulfate (DHEAS), and their relationships with clinical symptoms in men and women with Parkinson's disease. A 20-day course of real rTMS reduced the UPDRS and UPDRS III scores in patients with Parkinson's disease in comparison with the basal parameters (before rTMS), regardless of their sex. The level of cortisol did not change in men and women; at the same time, the content of DHEAS in men increased and before rTMS negatively correlated with the UPDRS scores. Sham rTMS had no effects on clinical parameters or hormonal levels. Possible mechanisms of sex-dependent differences in the effect of rTMS on the level of the neurosteroid hormone DHEAS are discussed.

RESUMO

The complex of climatic and geographical conditions of the Arctic determines the high intensity of the polysystem adaptive response of the organism, the duration of which is additionally influenced by individual genetic characteristics, social conditions, psychological and work loads. Taking into account the relevance of timely prevention and early diagnosis of stress-induced somatic pathology in EMERCOM employees working in unfavorable climatic and geographical zones, the authors evaluated the informative value of determining the level of steroid hormones and insulin as laboratory markers of adaptation to Arctic conditions. The expediency of developing objective criteria for the interpretation of the insulin/cortisol index and studying the informativeness of the 17ONprogesterone level as the earliest marker of adaptation to unfavorable climatic and geographical conditions of the Arctic is substantiated.

RESUMO

CONTEXT: Cortisol and dehydroepiandrosterone-sulfate (DHEA-S) are indispensable hormones for normal pregnancy. It is unclear if these hormones, specifically DHEA-S can offer value for predicting poor birth outcome. OBJECTIVE: To compare prenatal cortisol and DHEA-S levels among pregnant women with normal or poor birth outcome. METHODS: Plasma and saliva were collected prospectively from women in second-third trimester of pregnancy. Women with normal birth outcome (NBO) (n = 501) included live birth, no pregnancy complications and ≥2.5 kg infant birth weight. Women with poor birth outcome included adverse birth outcome (ABO) (n = 50) or low birth weight outcome (LBW) (n = 147). Enzyme-linked immunosorbent assay was performed to measure hormone concentrations in plasma and saliva. RESULTS: Circulatory-DHEA-S levels in pregnant women with ABO were higher than women with NBO (p = .043). Among ABO, only stillbirth cases demonstrated significant increase in circulatory-DHEA-S levels (p = .006). Circulatory and salivary cortisol/DHEA-S ratio was lower among women with stillbirth (p = .004) and ABO outcome (p = .043) respectively compared with women with NBO. Consistently, increased odds of ABO were observed in pregnant women with highest circulatory-DHEA-S levels (odds ratio quartile score 1 vs. 4, 2.79, p = .027) and lowest salivary cortisol/DHEA-S ratio (score 4 vs. 2, 2.83, p = .025). Increased odds of stillbirth outcome were observed in pregnant women with highest circulatory-DHEA-S levels (odds ratio quartile score 1 vs. 4, 8.47, p = .046) and lowest circulatory cortisol/DHEA-S ratio (score 4 vs. 1, 4.803, p = .048). Associations remained significant after adjusting for confounders. Women with LBW did not demonstrate significant changes in cortisol or DHEA-S levels. CONCLUSION: Prenatal measurement of DHEA-S or cortisol/DHEA-S ratio may offer significant value for predicting adverse birth, specifically stillbirth outcome.

RESUMO

OBJECTIVE: Identifying biomarkers is a priority in translational chronic pain research. Dehydroepiandrosterone (DHEA) and its sulfated form, DHEA-S, are adrenocortical steroids in the blood with neuroprotective properties that also produce sex hormones. They may capture key sex-specific neuroendocrine mechanisms of chronic pain. DESIGN: Cross-sectional study. METHODS: Using data from 1,216 community-dwelling adults aged 34-84 from the Midlife in the United States (MIDUS) cohort, we examined blood DHEA and DHEA-S levels in association with chronic pain in men and women, adjusting for demographics, chronic diseases, medications including opioids, and psychosocial factors. If an association was found, we further explored dose-response relationships by the number of pain locations and the degree of pain interference. RESULTS: In women, chronic pain was associated with 0.072 lower (95% confidence interval [CI], -0.127 to -0.017) log10 DHEA-S µg/dL, with pain in one to two locations associated with 0.068 lower (95% CI, -0.131 to -0.006) and in three or more locations 0.071 lower (95% CI, -0.148 to 0.007) log10 DHEA-S (P for trend = 0.074). Furthermore for women, low-interference pain was associated with 0.062 lower (95% CI, -0.125 to -0.000), whereas high-interference pain was associated with 0.138 lower (95% CI, -0.233 to -0.043) log10 DHEA-S (P for trend = 0.004). Chronic pain was not associated with DHEA or DHEA-S levels in men or DHEA levels in women. CONCLUSIONS: Chronic pain and its functional interference correspond to lower blood DHEA-S levels in women.

RESUMO

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.

RESUMO

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.

RESUMO

Serum dehydroepiandrosterone sulfate (DHEA-S) levels reflect the state of adrenocorticotropic hormone (ACTH) secretion. However, it is difficult to use serum DHEA-S to diagnose hypothalamic-pituitary-adrenal (HPA) axis insufficiency due to its non-normal and highly skewed distribution. In this study, we focused on HPA insufficiency caused by hypothalamic and/or pituitary dysfunction and evaluated the usefulness of the standard deviation score of log-transformed DHEA-S (ln DHEA-S SD score), which was calculated from the established age- and sex-specific reference values. We retrospectively reviewed the medical records of 94 patients suspected of having HPA insufficiency, in whom serum DHEA-S measurement and the rapid ACTH stimulation test were performed, and included 65 patients who met our criteria in this study. The ln DHEA-S SD scores were distributed more normally than measured DHEA-S levels and were significantly higher in patients with a peak cortisol level ≥18 µg/dL than in those below this value, suggesting that this score is a legitimate and strong indicator of adrenocortical function. The optimal cut-off value for impaired HPA function was -0.853, with a sensitivity of 70.3% and a specificity of 100%. Among the 37 patients whose peak cortisol levels were below 18 µg/dL, 11 patients with ln DHEA-S scores ≥-0.853 exhibited significantly higher basal ACTH and basal and peak cortisol levels than the 26 patients with scores <-0.853. Thus, this score plays a supportive role in evaluating HPA axis function, particularly in patients with borderline cortisol responses to ACTH.
