Serum Dehydroepiandrosterone Sulfate Levels Research Articles

Androgen synthesis cell-specific CREBZF deficiency alters adrenal cortex steroid secretion and develops behavioral abnormalities in adult male mice.

The global challenge of male infertility is escalating, notably due to the decreased testosterone (T) synthesis in testicular Leydig cells under stress, underscoring the critical need for a more profound understanding of its regulatory mechanisms. CREBZF, a novel basic region-leucine zipper transcription factor, regulates testosterone synthesis in mouse Leydig cells invitro; however, further validation through invivo experiments is essential. Our study utilized Cyp17a1-Cre to knock out CREBZF in androgen-synthesis cells and explored the physiological roles of CREBZF in fertility, steroid hormone synthesis, and behaviors in adult male mice. Conditional knockout (cKO) CREBZF did not affect fertility and serum testosterone level in male mice. Primary Leydig cells isolated from CREBZF-cKO mice showed impaired testosterone secretion and decreased mRNA levels of Star, Cyp17a1, and Hsd3b1. Loss of CREBZF resulted in thickening of the adrenal cortex, especially X-zone, with elevated serum corticosterone and dehydroepiandrosterone levels and decreased serum dehydroepiandrosterone sulfate levels. Immunohistochemical staining revealed increased expression of StAR, Cyp11a1, and 17β-Hsd3 in the adrenal cortex of CREBZF-cKO mice, while the expression of AR was significantly reduced. Along with the histological changes and abnormal steroid levels in the adrenal gland, CREBZF-cKO mice showed higher anxiety-like behavior and impaired memory in the elevated plus maze and Barnes maze, respectively. In summary, CREBZF is dispensable for fertility, and CREBZF deficiency in Leydig cells promotes adrenal function in adult male mice. These results shed light on the requirement of CREBZF for fertility, adrenal steroid synthesis, and stress response in adult male mice, and contribute to understanding the crosstalk between testes and adrenal glands.

Serum Dehydroepiandrosterone sulfate (DHEA-S) level and its potential impact on immune responses and symptom severity after Oxford-AstraZeneca COVID-19 vaccination

BackgroundDehydroepiandrosterone sulfate (DHEA-S) has been associated with an immunomodulatory function. This study aims to explore the relationship between serum levels of DHEA-S and the immune responses triggered by the Oxford–AstraZeneca COVID-19 vaccine in individuals candidate for vaccination. MethodsSerum levels of DHEA-S, cytokine release, antibody production and virus neutralization potential were assessed in 50 male and 50 female subjects before and 2 weeks after vaccination with Oxford–AstraZeneca COVID-19 vaccine. ResultsLevel of DHEA-S before and 2 weeks after first and second dose of vaccination was not different significantly. Levels of Interleukin (IL)-2 and Interferon (IFN)-γ were significantly higher in the supernatant of peripheral blood mononuclear cells (PBMCs) obtained from subjects 2 weeks after both first and second dose of vaccination compared to before vaccination. Serum levels of IgM 2 weeks after first dose of vaccination was significantly higher compared to before first dose of vaccination. However, serum levels of IgG 2 weeks after first and second dose of vaccination were significantly higher compared to before first and second dose of vaccination. The 50 % focus reduction neutralization test (FRNT50) titer was significantly higher 2 weeks after both first and second dose of vaccination compared to before vaccination. Levels of DHEA-S did not have significant correlation with levels of IL-2, IFN-γ, IgM and IgG, and FRNT50 before and after first and second dose of vaccination. Vaccination did not result in intense unwanted clinical presentations. ConclusionDHEA-S is not involved in the quality of protective immune response during Oxford-AstraZeneca COVID-19 vaccination.

The Correlation Between Interleukin -6 and Dehydroepiandrosterone Sulfate in Patients with Severe COVID-19

Background: Numerous studies have demonstrated that interleukin-6 (IL-6) and serum dehydroepiandrosterone sulfate levels are negatively correlated. Low DHEA-S levels may be associated with severe disease and clinically ailing patients in the context of infectious diseases. Individuals infected with Coronavirus disease who exhibit elevated levels of IL-6 may undergo a cytokine storm, which can result in severe manifestations and a dismal prognosis. Objectives: To examine the relationship between DHEA-S and Il-6 in patients exhibiting severe manifestations of COVID-19. Subjects and Methods: A case-control investigation with 79 patients, ranging in age from 36 to 74 years, who were admitted to the hospital due to severe COVID-19 disease. A control group of 72 ostensibly healthy individuals was also included in the study. Using the ELISA method, the concentrations of IL-6 and DHEA-S in the serum of both groups were determined. The statistical analyses involved the application of the Pearson correlation coefficient and the T-test. None of the authors present any conflicts of interest. Results: With a Pearson correlation coefficient (r) of -0.8349, the study revealed a highly significant negative correlation (P < 0.0001) between the mean IL-6 level (64.369 pg/ml ± 2.6237) and the mean DHEA-S level (1.2728 ng/ml ± 1.7005) in the study group. An exceptionally significant statistical disparity was also identified when IL-6 and DHEA-S levels were compared between the study and control groups. Conclusions: In severely infected COVID-19 patients inverse correlation between the levels of IL-6 and DHEA-S indicates that DHEA-S deficiency may play a role in cytokine storm formation for these patients.

Analysis of Endocrine and Inflammatory Markers in Preserved Ratio Impaired Spirometry.

Chronic Obstructive Pulmonary Disease (COPD) is a disease of the lungs characterized by chronic airflow obstruction. Individuals with preserved ratio impaired spirometry (PRISm) may be at risk for developing COPD. This study aimed to characterize PRISm and COPD patients in terms of their immune response and endocrine profile to identify differences extending beyond lung function. The participants performed the clinical assessment, pulmonary function test, and blood collection to determine serum hormone levels and concentrations of cytokine. Differences were observed in the nutritional status, lung function, and comorbidity. There were no differences in IL-6, IL-8, IL-10, IL-12, and TNF levels between PRISm and COPD groups. Both PRISm and COPD patients have lower dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEA-S) levels than controls. Correlation analysis of PRISm and COPD patients revealed positive correlations between serum levels of DHEA-S and DHEA, with forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC), which negatively correlated with IL-8 levels. The results indicated that despite differences in lung function parameters, the PRISm and COPD groups exhibited similarities in endocrine profile alterations. This study represents the first attempt to link endocrine with immune markers and lung function in individuals with PRISm.

Multiparametric arterial spin-labeling and diffusion-weighted imaging of phenotyping of polycystic ovaries

BackgroundPolycystic ovarian syndrome [PCO] is a worldwide endocrine disorder affecting women of reproductive age. Diagnosis and differentiation of PCO phenotypes are crucial for disease prognosis, fertility outcome, and treatment planning. This study aims to assess arterial spin labeling perfusion (ASL) and diffusion-weighted imaging (DWI) derived metrics in the diagnosis of PCO, differentiation of its phenotypes, and correlation of these metrics with laboratory measurements.ResultsASL and DWI of the pelvis were performed on 72 PCO patients and another 20 age-matched control group. Two observers measured the blood flow (BF) and ADC in the ovarian stroma. Serum levels of testosterone, dehydroepiandrosterone sulfate (DHEAS), and body mass index (BMI) were calculated. BF values were significantly higher in PCO patients than in control cases (P = 0.001), with area under the curve (AUC) of (0.94 and 0.89) and accuracy of (96% and 92%) for both observers, respectively. Also, BF values were significantly higher in classic than in non-classic PCO cases (P = 0.001), with AUC of (0.92 and 0.90) and accuracy of (91%) for both observers, respectively. ADC values were significantly lower in PCO patients than in control cases (P = 0.001), with AUC of (0.85 and 0.84) for the first observer and second observer, respectively. ADC values were significantly lower in classic PCO patients than in non-classic patients (P = 0.001), with AUC of (0.85 and 0.84) and accuracy of (77% and 81%) for both observers, respectively. Combined values of BF and ADC showed an accuracy of 91% and 86% for differentiating patient from control cases for both observers, respectively, and an accuracy of 92% for differentiating classic from non-classic PCO phenotypes. A significant correlation was found between ADC, BF metrics, and both serum testosterone and DHEAS levels (P < 0.05).ConclusionsCombination of ASL and ADC can be used in PCO diagnosis and can help in the differentiation of its phenotypes. Serum levels of testosterone and DHEAS have a significant correlation with ADC and BF metrics.

Bone density in patients with nonfunctional adrenal incidentaloma

Aims: Adrenal incidentalomas (AI) are adrenal masses that are detected incidentally in imaging studies performed for different reasons in people who do not have any complaints suggestive of adrenal gland disease. The overall prevalence, approximately just over 4%, increases with age. AI is detected in approximately 10% of people over the age of 70. In this context, we thought that CT imaging, which is already used in the diagnosis and follow-up of AI, can contribute to the evaluation of muscle and bone mass without creating additional costs. Methods: In this retrospective study, 39 patients who were followed up with NFAI by the endocrinology department and 30 healthy individuals with normal adrenal imaging in the abdominal CT examination as the control group were included. Patients with chronic diseases or drug use that may affect bone and muscle mass, and individuals in the postmenopausal period were excluded in this study. Endocrine tests performed to exclude autonomous cortisol secretion, pheochromocytoma and primary hyperaldosteronism; VMA and fractionated metanephrines in 24-hour urine, cortisol values after 1 mg dexamethasone suppression test, baseline serum dehydroepiandrosterone sulfate (DHEAS) levels and plasma aldosterone (ng/dl)/renin (ng/ml/hour) ratio were measured. Autonomous cortisol production was excluded in patients with serum cortisol below 1.8 mcg/dl after 1 mg dexamethasone suppression. Results: 39 patients with NFAI and 30 healthy volunteers participated in the study. In the NFAI group, 69.2% (n= 27) were female and 30.8% (n=12) were male. In the healthy control group 63.3% (n=19) of the people were female and 37.7% (n=11) were male. There was no statistically significant difference between the two groups in terms of gender (p=061). The mean age of the NFAI group is 43 and the mean age of the control group is 49, and there was no statistically significant difference in age between the two groups (p=0.06) Conclusion: No decrease was found in BMD and paravertebral muscle mass values in the measurements made at L1-3 vertebral level with CT in NAFI patients. Further studies are needed in a larger patient population where the results are evaluated together with the femur and vertebral BMD measurements by DXA method, and muscle strength and performance are evaluated in addition to muscle mass in terms of sarcopenia.

The impact of menopause and serum DHEA-S level on the severity of Covid-19

ObjectivesWe aimed to demonstrate the difference between premenopausal and postmenopausal women in respect of the clinical course and outcomes of Covid-19. We investigated the epidemiological and hormonal factors which influence the severity of the disease. Study designThis observational cross-sectional study included the female patients admitted to a Covid-19 outpatient clinic between July 2020 and June 2021 and diagnosed with a positive polymerase chain reaction test. Blood samples were obtained to determine the serum levels of follicle stimulating hormone, luteinizing hormone, estradiol, total testosterone and dehydroepiandrosterone sulfate. Main outcome measureOur primary outcome was the poor clinical course of the disease in postmenopausal women. Our secondary outcome was the contribution of hormonal status to the clinical course of the disease. ResultsOur cohort consisted of 253 female patients (85 with mild, 125 with moderate and 43 with severe disease; 101 at the premenopausal and 152 at the postmenopausal stage). There was a statistically significant difference between the patients in different severity groups regarding clinical data and serum levels of luteinizing hormone, follicle stimulating hormone, estradiol and dehydroepiandrosterone sulfate. Being one year younger decreased the odds of having severe Covid-19 0.338-fold relative to the group with mild disease. A decrease in the serum dehydroepiandrosterone sulfate level was associated with a 2.604-fold increase in the odds of having severe Covid-19 relative to the group with mild disease. Being postmenopausal increased the odds of having severe disease compared with mild disease by 2.687-fold. ConclusionsThe prognosis of Covid-19 is more favorable in premenopausal women compared with postmenopausal women. Age, postmenopausal status and serum levels of dehydroepiandrosterone sulfate are important predictors of the severity of Covid-19 for women.

Dehydroepiandrosterone Sulfate, an Adrenal Androgen, Is Inversely Associated with Prevalence of Dynapenia in Male Individuals with Type 2 Diabetes.

Dehydroepiandrosterone sulfate (DHEAS) is thought to be associated with life expectancy and anti-aging. Although skeletal muscle disorders are often found in diabetic people, the clinical significance of DHEAS in skeletal muscle remains unclear. Therefore, we aimed to determine whether DHEAS is associated with the development of skeletal muscle disorders in individuals with type 2 diabetes (T2D). A cross-sectional study was conducted in 361 individuals with T2D. Serum DHEAS levels, skeletal muscle mass index (SMI), handgrip strength (HS), and gait speed (GS) were measured in the participants. Pre-sarcopenia, sarcopenia, and dynapenia were defined according to the definitions of the AWGS 2019 criteria. DHEAS level was positively associated with HS but not with SMI or GS after adjustment of confounding factors. Multiple logistic regression analyses in total subjects showed that DHEAS level had an inverse association with the prevalence of dynapenia but not with the prevalence of pre-sarcopenia or sarcopenia. Furthermore, a significant association between DHEAS level and dynapenia was found in males but not in females. ROC curve analysis indicated that cutoff values of serum DHEAS for risk of dynapenia in males was 92.0 μg/dL. Therefore, in male individuals with T2D who have low serum levels of DHEAS, adequate exercise might be needed to prevent dynapenia.

Sex steroid hormones and allergic diseases in children: a pilot birth cohort study in the Japan Environment and Children’s Study cohort

BackgroundNumerous studies suggest that sex steroids might play a role in sex disparity observed in allergic diseases in adults. However, whether sex hormones influence allergic diseases in children remains unclear. The aim of the present study was to examine the association of sex steroid hormones with allergic disease in Japanese children.MethodsThe present cross-sectional study included 145 6-year-old children participating in a pilot birth cohort study in the Japan Environment and Children’s Study. Data on allergic diseases were obtained from questionnaires, and serum levels of sex steroid hormones and allergen-specific IgE were measured. Logistic regression was performed to evaluate the association of sex hormones with allergic diseases.ResultsAfter adjusted sex, amount of body fat at 6 years, parental history of allergic disease, and exposure to tobacco smoke, serum dehydroepiandrosterone sulfate level was significantly associated with reduced odds of any allergic disease (adjusted odds ratio, 0.58; 95% confidence interval, 0.36–0.93; P = 0.024) and serum follicle-stimulating hormone level was significantly associated with increased odds of any allergic disease (adjusted odds ratio, 2.04; 95% confidence interval, 1.01–4.11, P = 0.046). Dehydroepiandrosterone sulfate level showed a significant association with number of allergic diseases.ConclusionsThe current study findings suggest that sex hormones may play an important role in the development of allergic diseases in prepubertal children.

Normative Data on Dehydroepiandrosterone Sulphate (DHEAS) and its Attributes in Healthy Indian Children and Adolescents.

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 63.7g/dl (sensitivity 72.6%, specificity 64.4%) in girls and 82.2g/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.

Investigating the Relationship between Serum Levels of Dehydroepiandrosterone Sulfate (DHEAS) and Executive Function in Patients with Schizophrenia Compared to the Control group

Introduction: Schizophrenia is a chronic and debilitating mental disorder associated with psychosocial dysfunction and reduced quality of life. Neurosteroids modulate the functions of the brain and affect the activities of neurotransmitters. The present study aimed to investigate the relationship between the serum level of dehydroepiandrosterone sulfate (DHEAS) and executive function in patients with schizophrenia compared to the control group. Method: In this case-control study, 20 schizophrenic men hospitalized in the psychiatric department of 5th Azar Hospital in Gorgan in 1401 and 20 non-diseased men eligible to enter the study were selected. After measuring the serum level of DHEAS, executive function was evaluated using the Wisconsin Card Sorting Test. Data analysis was performed in SPSS software (version 18) using independent t-test, U-Man-Whitney, logistic regression, chi-score, and Fisher's exact test at a significance level of 0.05. Results: The two groups were similar in terms of age (P=0.4), marital status (P=0.06), and education level (P=0.1). There was no statistically significant difference in the serum level of DHEAS in the two groups. There was a statistically significant difference in the executive performance of the two groups in the items of spotting (P=0.001) and correct answers (P=0.002). Conclusion: In this study, the level of DHEAS in subjects with schizophrenia was lower than that of healthy people. The serum level of this hormone was inversely associated with the duration of schizophrenia and had a direct linear relationship with executive function in the number of categories and perseverative errors. These results can guide relevant experts in the direction of timely diagnosis and treatment measures for these people.

Dehydroepiandrosterone sulfate (DHEAS) in excreta is a good indicator of serum DHEAS in Japanese macaques (Macaca fuscata)

We developed a microplate enzyme immunoassay (EIA) to measure dehydroepiandrosterone sulfate (DHEAS) in the blood, urine, and feces of Japanese macaques and evaluated the relationship between serum DHEAS and excreta DHEAS. Our DHEAS EIA using heterological DHEA derivatives conjugated with enzyme was highly sensitive, and linearities and recoveries for all matrices of Japanese macaques were reliable. For the biological evaluation of the metabolism of DHEAS in Japanese macaques, dissolved DHEAS was injected into the subjects, and consecutively collected serum, urine, and fecal samples were analyzed. The peaks of serum DHEAS were observed 6 h after the administration, while those of urine and feces were observed after 24 h. The fluctuation of those in urine and feces were significantly correlated with serum DHEAS levels. In addition, we measured pregnanediol-glucuronide (PdG), and estrone-conjugate (E1C) in urine and fecal samples to investigate the effects of administrated DHEAS on these progesterone and estrogen metabolites. The peak of PdG was observed 24 h after administration, then declined sharply. The concentration of E1C increased 1 week after administration in two out of three subjects. Our results suggest that measuring urinary and fecal DHEAS with our EIA provides a non-invasive alternative to assessing DHEAS levels in the serum of Japanese macaques.

Endometrial Heparin-Binding Epidermal Growth Factor Gene Expression and Hormone Level Changes in Implantation Window of Obese Women with Polycystic Ovarian Syndrome

Polycystic ovarian syndrome (PCOS) is a common endocrine disorder amongst reproductive-age women, and 61% to 76% of women with PCOS are obese. Obese women with PCOS are usually burdened with infertility problems due to implantation failure. Thus, progesterone treatment is usually used to improve implantation rates. Although Hb-EGF expression is actively involved in endometrial receptivity and implantation, the data on heparin-binding epidermal growth factor (Hb-EGF) expression following progesterone therapy in obese women with PCOS are still lacking. To investigate the changes in serum follicle-stimulating hormone (FSH), luteinising hormone (LH), dehydroepiandrosterone sulphate (DHEA), progesterone and oestradiol levels and Hb-EGF expression in obese women with PCOS during the implantation window following progesterone therapy. A total of 40 participants aged 18-40 years old were recruited following the provision of written consent. The participants were divided into the obese PCOS, normal-weight PCOS, obese fertile and normal-weight fertile groups. First blood collection was done before ovulation. Then, daily oral micronised progesterone (Utrogestan 200 mg) was given to the PCOS group for 10 days. The treatment was followed by a second blood collection and endometrial tissue sampling by using a Pipelle de Cornier catheter. In the fertile group, ovulation was confirmed by using ultrasound, and a second blood sample was collected on days 7 to 9 postovulation. The serum levels of FSH, LH, DHEA, progesterone and oestradiol were measured in all participants. Wilcoxon signed-rank test was used to compare FSH, LH, DHEA, progesterone and oestradiol levels during pre- and postovulation. Mann-Whitney test was performed to compare FSH, LH, DHEA, progesterone and oestradiol levels between two groups: (1) the PCOS group and the fertile group, (2) the obese PCOS group and the non-obese PCOS group and (3) the obese group and the non-obese fertile group. Serum FSH levels were lower in obese women in their follicular phase than in women with normal weight regardless of their PCOS status, whereas serum LH/FSH ratios and DHEA levels were higher in women with PCOS than in women without PCOS. However, endometrial Hb-EGF expression was lower in the obese PCOS group than in the normal-weight PCOS group. Different patterns of hormonal levels and Hb-EGF expression levels were seen between the studied groups. However, further in vitro and in vivo studies are needed to investigate the mechanism underlying the changes in FSH, LH/FSH ratio, DHEA and Hb-EGF expression in PCOS after progesterone treatment.

Serum testosterone level correlates with left ventricular hypertrophy in older women.

Sex hormones may play an important role in age-related cardiac remodeling. However, their impact on cardiac structure and function in females of advanced age still remains unclear. The aim of this study is to evaluate the relationship between sex hormones level and echocardiographic parameters in older women with concomitant cardiovascular diseases. The study group included 52 community-dwelling women with mean age 79.5 ± 2.8 years, consecutive patients of an outpatient geriatric clinic. In all the subjects, a transthoracic echocardiogram was performed and serum testosterone, estradiol, follicle-stimulating hormone, luteinising hormone, dehydroepiandrosterone sulphate, and cortisol levels were determined. Testosterone level correlated positively with interventricular septum diastolic dimension (IVSd) (rS=0.293, p<0.05), left ventricular mass index (rS=0.285, p<0.05), E/E' ratio (rS=0.301, p<0.05), and negatively with E' (rS=-0.301, p<0.05). Estradiol level showed a positive correlation with the posterior wall dimension (rS=0.28, p<0.05). Besides, no significant correlations between clinical or echocardiographic parameters and other hormones were observed. Female subjects with diagnosed left ventricular hypertrophy (LVH) (n=34) were characterized by a significantly higher rate of hypertension (p=0.011), higher waist-to-height ratio (p=0.009), higher testosterone level (0.82 vs. 0.48 nmol/L, p=0.024), higher testosterone/estradiol ratio (16.4 vs. 9.9, p=0.021), and received more anti-hypertensive drugs (p=0.030). In a multiple stepwise logistic regression, the best determinants of LVH were the presence of hypertension (OR=6.51; 95% CI 1.62-26.1), and testosterone level (OR= 6.6; 95% CI 1.19-36.6). Higher serum testosterone levels may contribute to pathological cardiac remodeling, especially in hypertensive women. Estradiol, gonadotropins, DHEAS, and cortisol were not related to echocardiographic parameters.

Low serum dehydroepiandrosterone is associated with diabetic dyslipidemia risk in males with type 2 diabetes.

Sex steroid hormones are associated with the advancement of metabolic diseases such as dyslipidemia. This cross-sectional study aimed to investigate the relationship between dehydroepiandrosterone, dehydroepiandrosterone sulfate, androstenedione, and testosterone levels and the risk of dyslipidemia in people with type 2 diabetes mellitus. The analysis included 1,927 patients with type 2 diabetes mellitus. Serum dehydroepiandrosterone, dehydroepiandrosterone sulfate, androstenedione, and testosterone levels were determined using lipid chromatography-tandem mass spectrometry. Multivariable analyses were performed to investigate the association between the variables and dyslipidemia. The multivariable-adjusted odds ratio (OR) and 95% confidence interval (CI) of dyslipidemia across DHEA tertiles were 0.39 and 0.24-0.64, respectively (p trend = 0.001). This relationship was still maintained when analyzed as a continuous variable (odds ratio, 0.96; 95% confidence interval, 0.92-0.99; P < 0.01). However, in males with type 2 diabetes mellitus, no significant correlations were found between rising levels of dehydroepiandrosterone sulfate, androstenedione, and total testosterone and the risk of dyslipidemia (all P > 0.05). Furthermore, there was no significant association between androgen precursors and total testosterone with regard to the risk of developing dyslipidemia (all P > 0.05). Serum dehydroepiandrosterone levels were substantially and adversely correlated with dyslipidemia in adult men with T2DM. These results indicated that dehydroepiandrosterone may have an essential role in the development of dyslipidemia. More prospective research is required to validate this link.

Reference range of testosterone and dehydroepiandrosterone sulfate levels in women during reproductive age in the Iranian population.

To determine the average cutoff values of serum-free and total testosterone (FT, TT) and dehydroepiandrosterone sulfate (DHEAS) among healthy premenopausal women. Participants were women aged 18-55 years without signs and symptoms of hyperandrogenism (n = 489). Participants if Ferriman-Gallwey (FG) scores between 6 and 8 were considered a group located in the upper spectrum related to the normal hirsutism score (n = 30). DHEAS, TT, and FT levels were compared between different populations. Upper limits of 97.5 and 95 and lower limits of 5 and 2.5 percentiles were calculated to provide the reference intervals for DHEA, TT, and FT in the total sample and in the population with FG 6-8. In the total population, the mean ± standard deviation (SD) serum FT, TT, and DHEAS levels were 1.40 ± 0.63 pg/mL, 0.42 ± 0.17 ng/mL, and 1.5 ± 0.97 µg/ml, respectively. The cutoff values of FT at 1.35 and TT at 0.49 were obtained for differentiating the patients with FG 6-8 scores from the normal population, with the corresponding specificity of 0.60, the sensitivity of 0.67, and area under the ROC curve (AUC) (confidence interval 95%) of 0.63 (0.52-0.73), P = 0.01 and 0.68 (0.58-0.78) P = 0.001, respectively. In our study, the mean ± SD serum FT level was 1.40 ± 0.63 pg/mL, the TT level was 0.42 ± 0.17 ng/mL, and the DHEAS level was 1.5 ± 0.97 µg/ml, in premenopausal women between 18 and 49 years of age. Furthermore, in a population with FG 6-8 score, a cutoff value of FT at 1.35 and TT at 0.49 was obtained. Although the irregular menstrual cycle did not change the reference range when compared with the normal group.

Serum levels of dehydroepiandrosterone sulfate are associated with a lower risk of mobility-subtype frailty in older Japanese community-dwellers

PurposePrevious studies suggest that lower serum levels of dehydroepiandrosterone sulfate (DHEA-S) are associated with physical frailty. Associations with subtypes of physical frailty have not been studied. This study aimed to investigate associations between serum DHEA-S levels and physical frailty and its subtypes in older Japanese community-dwellers using panel data. MethodsThis study was conducted within the National Institute for Longevity Sciences-Longitudinal Study of Aging (NILS-LSA). Repeated measurement data were collected from 1,886 older community-dwellers (60–91 years). Frailty was identified according to modified Cardiovascular Health Study criteria (weight loss, weakness, slowness, exhaustion, low physical activity) and was classified into following subtypes: mobility (weakness/slowness), non-mobility (weight loss/exhaustion), and low physical activity. Associations with serum DHEA-S (sex-specific tertiles [T1−T3]) were estimated by random-effects logistic regression models adjusting for age, sex, education, disease history (stroke, hypertension, heart disease, diabetes), smoking status, depressive symptoms, and survey wave. ResultsWe found an average prevalence of 6.0% for frailty (mobility subtype, 7.0%; non-mobility subtype, 34.8%; low physical activity subtype, 9.4%) across survey waves. Mean (SD) sex-specific DHEA-S levels (μg/dL) at T1, T2, and T3 were 46.8 (20.8), 88.7 (28.4), and 158.0 (58.9), respectively. Compared with T1, the adjusted ORs (95% CIs) for frailty were 0.69 (0.44, 1.08) for T2 and 0.50 (0.30, 0.83) for T3 (P trend = 0.007). The corresponding values for mobility subtype were 0.80 (0.51, 1.24) for T2 and 0.55 (0.33, 0.90) for T3. ConclusionHigher serum DHEA-S levels were associated with lower risk of frailty, especially mobility-subtype frailty, in older community-dwellers.

Low serum allopregnanolone levels in children with attention deficit hyperactivity disorder

Attention deficit hyperactivity disorder (ADHD) has increasing evidence for the role of neurohormones in its etiopathogenesis. It has been suggested that the effects of neurosteroids on the brain in the early developmental period may predispose to neurodevelopmental pathologies. In our study, we examined serum dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEA-S), and allopregnanolone levels in children with ADHD and whether these neurosteroids differ in the presence of specific learning disorder (SLD) and oppositional defiant disorder (ODD) comorbidities (ADHD+SLD and ADHD+ODD). We also investigated the relationship between neurosteroid levels and the severity of ADHD symptoms. Thirty-five prepubertal children with ADHD and 33 prepubertal healthy children, all aged 6–10 years, were included in this study. The severity of ADHD symptoms was assessed with the parent-rated and teacher-rated Turgay DSM-IV Disruptive Behavior Disorders Rating Scale (T-DSM-IV-S). Serum allopregnanolone levels were significantly lower in the ADHD group compared to healthy controls. When analyzed according to comorbidity status, serum allopregnanolone levels were lower in ADHD+SLD and ADHD+ODD groups compared to healthy controls. However, when compared to healthy children, serum DHEA and DHEA-S levels in children with ADHD were not significantly different. Serum allopregnanolone levels were negatively associated with teacher-rated T-DSM-IV-S hyperactivity/impulsivity scores for all participants only. These findings suggest that allopregnanolone may play a role in the pathophysiology of ADHD, especially in the presence of ODD and SLD comorbidities.

COVID-19 patients with altered steroid hormone levels are more likely to have higher disease severity.

PurposeThis study aims to evaluate the correlations between the severity of the disease and serum steroid levels by analyzing the serum steroid levels in COVID-19 patients with different levels of disease progression and the control group.MethodsMorning serum Aldosterone, 11-deoxycortisol, Androstenedione, 17-hydroxyprogesterone, Dihydrotestosterone (DHT), Dehydroepiandrosterone (DHEA), Corticosterone, Dehydroepiandrosterone sulfate (DHEAS), Estrone, Estradiol, Progesterone, 11-deoxycorticosterone, Cortisol, Corticosterone, Androsterone, Pregnenolone, 17-hydroxypregnenolone and 21-deoxycortisol levels were measured in 153 consecutive patients were grouped as mild, moderate, and severe based on the WHO COVID-19 disease severity classification and the control group. Steroid hormone levels were analyzed at once with a liquid chromatography-tandem mass spectrometric method (LC-MS/MS).ResultsIn our study, nearly all steroids were statistically significantly higher in the patients’ group than in the control group (p < 0.001). Also, DHEA was an independent indicator of the disease severity with COVID-19ConclusionsOur study reveals that the alteration in steroid hormone levels was correlated with disease severity. Also, steroid hormone levels should be followed up during COVID-19 disease management.
