RESUMO

Polycystic ovary syndrome (PCOS) is the most prevalent endocrine disorder that affects women of reproductive age. Aim - to determine the association between body mass index, hirsutism, acne, and hormonal status with Polycystic ovary syndrome. This cross-sectional study included 55 women with PCOS, between the ages of 18 and 39 who attended the Obstetrics and Gynecology Clinic at the University Clinical Center of Kosovo (UCCK). Body mass index (BMI) was calculated and luteinizing hormone (LH), follicle stimulating hormone (FSH), LH/FSH ratio, testosterone and dehydroepiandrosterone sulfate (DHEA-S) values were determined. All the data were analyzed after the clinic-endocrine profile was assessed. The average age of women with PCOS was 21.36±4.29. Hirsutism and acne were quite conspicuous, as well as testosterone and DHEA-S values. Moreover, women with PCOS had higher values of LH and LH/FSH ratio (8.17±9.66 and 2.86±2.74) but not FSH values (4.16±2.97) that showed a positive correlation with polycystic ovary syndrome. Thus, PCOS is a multifaceted endocrine and metabolic disorder, which needs early recognition and treatment to prevent long-term complications.

RESUMO

Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder in women of reproductive age, which often leads to female infertility. Chronic inflammation is a significant factor in the development of PCOS. Our study aimed to explore the impact of mesencephalic astrocyte-derived neurotrophic factor (MANF), a scientifically validated anti-inflammatory factor, on 99 diagnosed PCOS patients. We also investigated its effects on PCOS mice induced with dehydroepiandrosterone (DHEA) and KGN cells induced with dihydrotestosterone (DHT). Our findings revealed a decrease in serum MANF levels in PCOS patients, which were negatively associated with serum tumor necrosis factor-α (TNF-α) and interleukin-1ß (IL-1ß) levels. The administration of recombinant human MANF (rhMANF) in PCOS mice demonstrated a decrease in pro-inflammatory cytokines and monocytes/macrophages in both peripheral blood and ovarian tissues. Furthermore, the inclusion of rhMANF notably ameliorated DHEA-induced ovarian dysfunction and fibrosis by negatively regulating the toll-like receptor 4 (TLR4)-nuclear factor kappa B (NF-κB)-NLR family, pyrin domain containing protein 3 (NLRP3) pathway. Additionally, in vitro experiments showed that the up-regulation of MANF offset DHT-induced inhibition of viability and apoptosis in KGN cells. Collectively, this study highlights the anti-inflammatory properties of MANF in PCOS and suggests its potential as a therapeutic approach for the management of PCOS.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Gui Shen Wan (GSW) stands out as a promising therapeutic approach for addressing Premature Ovarian Insufficiency (POI). With deep roots in traditional medicine, GSW highlights the ethnopharmacological significance of herbal interventions in addressing nuanced aspects of women's health, with a specific emphasis on ovarian functionality. Recognizing the importance of GSW in gynecological contexts resonates with a rich tradition of using botanical formulations to navigate the intricacies of reproductive health. Delving into GSW's potential for treating POI emphasizes the crucial role of ethnopharmacological insights in guiding modern research endeavors. AIM OF THE STUDY: GSW is extensively utilized in gynecological disorders and has recently emerged as a potential therapeutic approach for POI. The present investigation aimed to assess the efficacy of GSW in treating POI in rats and elucidate its underlying molecular mechanisms. MATERIALS AND METHODS: The study employed GSW for POI treatment in rats. GSW, prepared as pills, underwent HPLC fingerprinting for quality control. Reagents and drugs, including VCD and dehydroepiandrosterone (DHEA), were sourced from reputable providers. Eighty Sprague-Dawley rats were categorized into groups for POI induction and treatment. Ovarian tissue underwent HE staining, immunohistochemical staining, Western Blot, qRT-PCR, and vaginal secretion testing. ELISA was utilized for target molecule detection. This methodology ensures a robust and reliable experimental framework. RESULTS: The results highlight a robust collaborative improvement in POI among rats subjected to combined GSW and DHEA treatment. Particularly noteworthy is the substantial enhancement in the expression of vascular regeneration-related molecules-VDR-Klotho-VEGFR-accompanied by a significant elevation in autophagy levels. Post-GSW administration, rat ovarian morphology demonstrated increased stability, hormone levels exhibited more consistent maintenance, and there was a marked reduction in inflammatory response compared to other groups (p < 0.01). Furthermore, GSW intervention resulted in a more pronounced upregulation of ovarian autophagy (p < 0.05). CONCLUSION: By modulating VDR-Klotho signaling, GSW exerts regulatory control over ovarian autophagy and vascular regeneration, thereby mitigating the occurrence and progression of POI in rats.

RESUMO

Therapies utilised in breast cancer management have been found to induce or worsen the genitourinary symptoms of menopause (GSM), a group of physical symptoms associated with the systemic loss of estrogen. These symptoms are often undertreated due to concerns surrounding cancer recurrence, especially when considering treatments with possible pro-estrogenic effects. As breast cancer prognosis continues to improve, clinicians are increasingly focussing on managing these symptoms amongst survivors. This systematic review primarily aimed to determine the risk of breast cancer recurrence amongst survivors using vaginal hormones and selective estrogen receptor modulator therapies recommended for use in GSM in the United Kingdom amongst currently published randomised clinical trials (RCTs). The secondary aim was to determine whether these RCTs demonstrated a significant rise in serum estrogen levels following the use of these therapies. A literature search revealed three RCTs suitable for assessment, two evaluating vaginal estrogen and one evaluating vaginal DHEA treatment. Our review determined that amongst published RCTs, no studies have aimed to assess for breast cancer recurrence; however among the studies observing for serious adverse effects of vaginal estrogen preparations, none have reported an increased incidence. Furthermore, these studies did not report a persistent or significant increase in serum estrogen levels following the use of vaginal estrogen products and low concentration (3.25 mg/day) DHEA gel. Larger RCTs studying commonly used vaginal preparations and selective estrogen receptor modulator treatments for GSM over longer follow-up periods will be vital to better assess the risk of breast cancer recurrence in survivors receiving these treatments.

RESUMO

IMPORTANCE: Whether dehydroepiandrosterone (DHEA) supplementation improves cognitive performance in older women is uncertain. Nonetheless, DHEA supplements are readily available over the counter in several countries and are potentially being used to prevent cognitive decline and dementia. OBJECTIVE: This systematic review was conducted to evaluate the effect of exogenous DHEA on cognitive performance in postmenopausal women. EVIDENCE REVIEW: Ovid MEDLINE, EMBASE, PsycINFO, Web of Science Core Collection, and the Cochrane Central Register of Controlled Trials databases were searched for studies of postmenopausal women until November 30, 2022. Eligible studies were required to be randomized clinical trials, be at least single blind, have a placebo or comparator arm and published in English. Risk of bias of the included studies was assessed by the revised Cochrane risk-of-bias tool. FINDINGS: Of the 15 articles retrieved for full-text review, four met the inclusion criteria. In all studies DHEA was administered as a 50-mg oral daily dose and all were double blind with an identical placebo. Three were placebo-controlled, crossover studies and one was a parallel-group clinical trial. The only positive outcome was limited to a 4-wk cross-over study in which DHEA statistically significantly enhanced five of six tests of visual-spatial performance compared with placebo in 24 cognitively normal postmenopausal women. Improvement in cognitive performance with DHEA treatment over placebo group was not seen in any other study. Heterogeneity of design and use of multiple measures of cognitive performance was a barrier to meta-analysis and between study comparisons. The studies were limited by high risk of bias in multiple domains. CONCLUSION AND RELEVANCE: Overall, this systematic review does not support a beneficial effect of DHEA therapy on cognitive performance in postmenopausal women.

RESUMO

OBJECTIVE: To systematically review the literature and provide clinical practice guidelines regarding various nonestrogen therapies for treatment of genitourinary syndrome of menopause (GSM). DATA SOURCES: MEDLINE, EMBASE, ClinicalTrials.gov , and Cochrane databases were searched from inception to July 2021. We included comparative and noncomparative studies. Interventions and comparators were limited to seven products that are commercially available and currently in use (vaginal dehydroepiandrosterone [DHEA], ospemifene, laser or energy-based therapies, polycarbophil-based vaginal moisturizer, Tibolone, vaginal hyaluronic acid, testosterone). Topical estrogen, placebo, other nonestrogen products, as well as no treatment were considered as comparators. METHODS OF STUDY SELECTION: We double-screened 9,131 abstracts and identified 136 studies that met our criteria. Studies were assessed for quality and strength of evidence by the systematic review group. TABULATION, INTEGRATION, AND RESULTS: Information regarding the participants, details on the intervention and comparator and outcomes were extracted from the eligible studies. Alternative therapies were similar or superior to estrogen or placebo with minimal increase in adverse events. Dose response was noted with vaginal DHEA and testosterone. Vaginal DHEA, ospemifene, erbium and fractional carbon dioxide (CO 2 ) laser, polycarbophil-based vaginal moisturizer, tibolone, hyaluronic acid, and testosterone all improved subjective and objective signs of atrophy. Vaginal DHEA, ospemifene, tibolone, fractional CO 2 laser, polycarbophil-based vaginal moisturizer, and testosterone improved sexual function. CONCLUSION: Most nonestrogen therapies are effective treatments for the various symptoms of GSM. There are insufficient data to compare nonestrogen options to each other.

RESUMO

Given their association with aging, growth hormone (GH), dehydroepiandrosterone (DHEA), and melatonin (N-acetyl-5-methoxytryptamine) have been evaluated as potential antiaging treatments. It has been hypothesized that declining endocrine function, specifically the decreases in hormone production and secretion seen with aging, plays a role in development of frailty. This physiologic decrease in hormone levels differs from a pathologic decrease due to a condition or disease. However, the signs and symptoms can be similar. Hormone replacement therapy is a well-established treatment for many conditions, but its role in the healthy aging process remains unclear. Off-label use of these hormones has shown some short-term benefits, such as improved body composition, mood, neurocognition, and sexual function and decreased oxidative stress. However, there are no recommendations for routine measurement of these hormone levels or for hormone replacement therapy because of a lack of high-quality evidence. Long-term studies are needed to evaluate the efficacy and safety of GH, DHEA, and melatonin if they are to be used as antiaging therapies.

RESUMO

BACKGROUND: Hodgkin's lymphoma (HL) is one of the most common malignant lymphoproliferative diseases. Chemotherapy and radiotherapy used in the treatment of LH induce a number of toxic effects leading to dysfunction of endocrine system. Hormonal disorders in HL and their relationships with the therapy used remain to be clarified. AIM: To assess disorders of the endocrine function of thyroid, parathyroid glands and gonads in HL survivors. MATERIALS AND METHODS: Screening of endocrine dysfunction of the thyroid, parathyroid glands and gonads was performed in 160 adult patients with HL, 55 men and 105 women, at remission stage induced by chemotherapy or chemoradiotherapy. Forty healthy subjects, matched by age, were acted as control. The levels of TSH, T3, free T4, PTH, FSH, LH, free testosterone, dehydroepiandrosterone sulfate (DHEA-S), and sex-hormone binding globulin (SHBG) were measured in blood serum by ELISA. Bone mineral density (BMD) was assessed by DEXA. RESULTS: Hypothyroidism (25%), hyperparathyroidism (15.6%) and hypogonadism (29% of men and 25.3% of women) were the most prevalent endocrine disorders in LH survivors. Hypothyroidism was significantly more common in patients after chemoradiotherapy than in those who received only chemotherapy (χ2=9.4, р=0.002). In patients with hyperparathyroidism, there were negative correlations between PTH levels and BMD in the lumbar spine (r=-0.74, p=0.00002) and in the femoral neck (r=-0.66, p=0.0003). Men with HL demonstrated lower free testosterone concentrations when compared to control (p=0.04); LH and FSH levels were elevated (p=0.0004 and p=0.04, respectively). In men with HL the levels of DHEA-S were reduced (p=0.0009). The increased SHBG concentrations were revealed in 13 (23.6%) men. Women of reproductive age with HL had higher levels of LH in the luteal phase (p=0.05) and FSH in the follicular phase (p=0.02) than controls. CONCLUSION: The data indicate a high prevalence of the dysfunctions of thyroid, parathyroid glands, and gonads in HL survivors. Screening for endocrine disorders in these patients is highly recommended.

RESUMO

BACKGROUND: Assisted reproductive technology (ART) has brought good news to infertile patients, but how to improve the pregnancy outcome of poor ovarian response (POR) patients is still a serious challenge and the scientific evidence of some adjuvant therapies remains controversial. AIM: Based on previous evidence, the purpose of this systematic review and network meta-analysis was to evaluate the effects of DHEA, CoQ10, GH and TEAS on pregnancy outcomes in POR patients undergoing in vitro fertilization and embryo transplantation (IVF-ET). In addition, we aimed to determine the current optimal adjuvant treatment strategies for POR. METHODS: PubMed, Embase, The Cochrane Library and four databases in China (CNKI, Wanfang, VIP, SinoMed) were systematically searched up to July 30, 2022, with no restrictions on language. We included randomized controlled trials (RCTs) of adjuvant treatment strategies (DHEA, CoQ10, GH and TEAS) before IVF-ET to improve pregnancy outcomes in POR patients, while the control group received a controlled ovarian stimulation (COS) regimen only. This study was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The surface under the cumulative ranking curve (SUCRA) was used to provide a pooled measure of cumulative ranking for each outcome. RESULTS: Sixteen RCTs (2323 women) with POR defined using the Bologna criteria were included in the network meta-analysis. Compared with the control group, CoQ10 (OR 2.22, 95% CI: 1.05 to 4.71) and DHEA (OR 1.92, 95% CI: 1.16 to 3.16) had obvious advantages in improving the clinical pregnancy rate. CoQ10 was the best in improving the live birth rate (OR 2.36, 95% CI: 1.07 to 5.38). DHEA increased the embryo implantation rate (OR 2.80, 95%CI: 1.41 to 5.57) and the high-quality embryo rate (OR 2.01, 95% CI: 1.07 to 3.78) and number of oocytes retrieved (WMD 1.63, 95% CI: 0.34 to 2.92) showed a greater advantage, with GH in second place. Several adjuvant treatment strategies had no significant effect on reducing the cycle canceling rate compared with the control group. TEAS was the least effective of the four adjuvant treatments in most pooled results, but the overall effect appeared to be better than that of the control group. CONCLUSION: Compared with COS regimen, the adjuvant use of CoQ10, DHEA and GH before IVF may have a better clinical effect on the pregnancy outcome of POR patients. TEAS needs careful consideration in improving the clinical pregnancy rate. Future large-scale RCTs with direct comparisons are needed to validate or update this conclusion.

RESUMO

INTRODUCTION: Diminished ovarian reserve remains a challenge in the reproductive medicine field. Treatment options for these patients are limited and there is no consensus to make any recommendations. Regarding adjuvant supplements, DHEA could play a role in follicular recruitment and, therefore, may increase spontaneous pregnancy rate. MATERIALS AND METHODS: This study was a monocentric historical and observational cohort study carried out in the reproductive medicine department at the University Hospital, Femme-Mère-Enfant in Lyon. All women presenting with a diminished ovarian reserve treated with 75mg/day of DHEA were consecutively included. The main objective was to evaluate the spontaneous pregnancy rate. The secondary objectives were to identify predictive factors for pregnancy and the evaluation of treatment side effects. RESULTS: Four hundred and thirty-nine women were included. In all, 277 were analyzed, 59 had a spontaneous pregnancy (21.3%). The probability of being pregnant was respectively 13.2% (IC95 9-17.2%), 21.3% (IC95 15.1-27%) and 38.8% (IC95 29.3-48.4%) at 6, 12 and 24 months. Only 20.6% of patients complained of side effects. CONCLUSION: DHEA may improve spontaneous pregnancies in women with diminished ovarian reserve without any stimulation.

RESUMO

Background: Dehydroepiandrosterone (DHEA) may improve the outcomes of patients with poor ovarian response (POR) or diminished ovarian reserve (DOR) undergoing IVF/ICSI. However, the evidence remains inconsistent. This study aimed to investigate the efficacy of DHEA supplementation in patients with POR/DOR undergoing IVF/ICSI. Methods: PubMed, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI) were searched up to October 2022. Results: A total of 32 studies were retrieved, including 14 RCTs, 11 self-controlled studies and 7 case-controlled studies. In the subgroup analysis of only RCTs, DHEA treatment significantly increased the number of antral follicle count (AFC) (weighted mean difference : WMD 1.18, 95% confidence interval(CI): 0.17 to 2.19, P=0.022), while reduced the level of bFSH (WMD -1.99, 95% CI: -2.52 to -1.46, P<0.001), the need of gonadotropin (Gn) doses (WMD -382.29, 95% CI: -644.82 to -119.76, P=0.004), the days of stimulation (WMD -0.90, 95% CI: -1.34 to -0.47, P <0.001) and miscarriage rate (relative risk : RR 0.46, 95% CI: 0.29 to 0.73, P=0.001). The higher clinical pregnancy and live birth rates were found in the analysis of non-RCTs. However, there were no significant differences in the number of retrieved oocytes, the number of transferred embryos, and the clinical pregnancy and live birth rates in the subgroup analysis of only RCTs. Moreover, meta-regression analyses showed that women with lower basal FSH had more increase in serum FSH levels (b=-0.94, 95% CI: -1.62 to -0.25, P=0.014), and women with higher baseline AMH levels had more increase in serum AMH levels (b=-0.60, 95% CI: -1.15 to -0.06, P=0.035) after DHEA supplementation. In addition, the number of retrieved oocytes was higher in the studies on relatively younger women (b=-0.21, 95% CI: -0.39 to -0.03, P=0.023) and small sample sizes (b=-0.003, 95% CI: -0.006 to -0.0003, P=0.032). Conclusions: DHEA treatment didn't significantly improve the live birth rate of women with DOR or POR undergoing IVF/ICSI in the subgroup analysis of only RCTs. The higher clinical pregnancy and live birth rates in those non-RCTs should be interpreted with caution because of potential bias. Further studies using more explicit criteria to subjects are needed.

RESUMO

The vagina is traditionally thought of as a passive organ in the female reproductive system, serving primarily as a passageway for menstrual blood, sexual intercourse and childbirth. However, recent research has shed light on the vagina's role as an endocrine organ that plays a crucial role in female hormonal balance and overall health. Particularly, growing evidence shows that the human vagina can be considered both as source and target of androgens, in view of the novel concept of 'intracrinology'. Besides the well-known role of estrogens, androgens are also crucial for the development and maintenance of healthy genitourinary tissues in women. As androgen levels decline with age, and estrogen levels fall during the menopausal transition, the tissues in the vagina, together with those in the urinary tract, become thinner, drier and less elastic, leading to a variety of uncomfortable and sometimes painful symptoms, clustered in the genitourinary syndrome of menopause (GSM). Given the lack of testosterone-based or androstenedione-based products approved by regulatory agencies to treat GSM, the possibility of using intravaginal prasterone, which works by providing a local source of dehydroepiandrosterone (DHEA) to the vaginal tissues, appears to be a targeted treatment. Further studies are needed to better assess its safety and efficacy.

RESUMO

OBJECTIVE: Pelvic organ prolapse (POP) occurs predominantly in postmenopausal women. Restoration of the proper estrogenization of vaginal mucosa is important in preoperative and postoperative treatment, increasing the effectiveness of this approach. The objective of this study was the development of intravaginal vaginal suppositories containing DHEA and comparison of the clinical effects of vaginal topical therapy with DHEA, estradiol, or antibiotic after POP surgery. METHOD: Nine types of vaginal suppositories containing 6.5 mg DHEA in different bases were prepared to find optimal formulation for the vaginal conditions. Ninety women referred for POP surgery were randomly assigned to one of three groups receiving topical treatment in the postoperative period (estradiol, DHEA, or antibiotic). On admission to hospital and during follow-up vaginal pH, vaginal maturation index and vaginal symptoms were assessed. RESULTS: Vaginal suppositories with the base made from polyethylene glycol 1,000 without surfactants characterized the highest percentage of the released DHEA. In women treated with topical estradiol or DHEA a significant decrease in the number of parabasal cells, increase in superficial and intermediate cells in the vaginal smears, decrease in vaginal pH, and reduction of vaginal symptoms were observed. CONCLUSIONS: The use of topical therapy with DHEA or the use of topical therapy with estradiol in the postoperative period were both shown to improve maturation index, vaginal pH, and vaginal symptoms. The benefits of topical therapy with DHEA after pelvic organ prolapse repair brings similar results as estradiol, without potential systemic exposure to increased concentrations of sex steroids above levels observed in postmenopausal women.

RESUMO

AIMS: Phytoestrogens can act as natural estrogens owing to their structural similarity to human estrogens. Biochanin-A (BCA) is a well-studied phytoestrogen with a wide variety of pharmacological activities, whereas not reported in the most frequently encountered endocrinopathy called polycystic ovary syndrome (PCOS) in women. PURPOSE: This study aimed to investigate the therapeutic effect of BCA on dehydroepiandrosterone (DHEA) induced PCOS in mice. MAIN METHODS: Thirty-six female C57BL6/J mice were divided into six groups: sesame oil, DHEA-induced PCOS, DHEA + BCA (10 mg/kg/day), DHEA + BCA (20 mg/kg/day), DHEA + BCA (40 mg/kg/day), and metformin (50 mg/kg/day). KEY FINDINGS: The results showed a decrease in obesity, elevated lipid parameters, restoration of hormonal imbalances (testosterone, progesterone, estradiol, adiponectin, insulin, luteinizing hormone, and follicle-stimulating hormone), estrus irregular cyclicity, and pathological changes in the ovary, fat pad, and liver. SIGNIFICANCE: In conclusion, BCA supplementation inhibited the over secretion of inflammatory cytokines (TNF-α, IL-6, and IL-1ß) and upregulated TGFß superfamily markers such as GDF9, BMP15, TGFßR1, and BMPR2 in the ovarian milieu of PCOS mice. Furthermore, BCA reversed insulin resistance by increasing circulating adiponectin levels through a negative correlation with insulin levels. Our results indicate that BCA attenuated DHEA-induced PCOS ovarian derangements, which could be mediated by the TGFß superfamily signaling pathway via GDF9 and BMP15 and associated receptors as first evidenced in this study.

RESUMO

Diminished ovarian reserve (DOR) refers to the decline in fertility caused by the loss of normal ovarian function. DOR is associated with adverse reactions to ovarian stimulation during in vitro fertilization and embryo transfer (IVF-ET), increasing cycle cancellation rates and reducing pregnancy rates. Although it is well known that dehydroepiandrosterone (DHEA) can be used as a dietary supplement for age-related diseases, its potential has gradually been shown for many diseases. In this review, we focus on the effects of DHEA on DOR, briefly analysing its clinical benefits and limitations and describing the mechanism of function and the clinical trials conducted. Therefore, we summarize the mechanisms and indications of DHEA for DOR.

RESUMO

AIMS: Although nerolidol (NRL) is a naturally occurring sesquiterpene alcohol with many pharmacological activities, its role in dehydroepiandrosterone DHEA-induced polycystic ovary syndrome PCOS is unknown. This study aims to explore the potential beneficial effects and underlying molecular mechanisms of nerolidol treatment on polycystic ovary syndrome. MAIN METHODS: Pre-pubertal female Sprague-Dawley rats were randomly assigned into four groups (n = 8/group); group I: control; group II: PCOS; group III: P + NRL; group IV: NRL. Biochemical parameters related to oxidative stress, inflammation, apoptosis, and hormones were estimated in the blood and ovarian tissues. Histopathological, ultrastructural, and immunohistochemical analyses were performed. Bax, P53, Cas-3, and Bcl-2 gene expression levels were detected with RT-PCR. The membrane array analysis detected chemokine, cytokine, and growth factor protein profiles. KEY FINDINGS: In light of the available data, it can deduce that nerolidol has a significant ameliorating effect on lipid peroxidation, oxidative stress, inflammation, histopathological damage, and apoptosis accompanying PCOS in female rats. SIGNIFICANCE: PCOS is not only a reproductive pathology but also a systemic condition and its etiopathogenesis is still not fully understood. Since changes in PCOS have important long-term effects on health, this study evaluated the efficacy of nerolidol, a phytotherapeutic for the control of biochemical, apoptotic, histopathological, and metabolic changes.

RESUMO

Dehydroepiandrosterone (DHEA) is the most abundant steroid hormone in primates, which is predominantly synthesized in the adrenal cortex. A characteristic curve of growth and decline of its synthesis during life was observed, together with the corresponding formation of its sulphate ester (DHEAS). High levels of plasma circulating DHEA are suggested as a marker of human longevity, and various pathophysiological conditions lead to a decreased DHEA level, including adrenal insufficiency, severe systemic diseases, acute stress, and anorexia. More recent studies have established the importance of DHEA in the central nervous system (CNS). A specific intranuclear receptor for DHEA has not yet been identified; however, highly specific membrane receptors have been detected in endothelial cells, the heart, kidney, liver, and the brain. Research shows that DHEA and DHEAS, as well as their metabolites, have a wide range of effects on numerous organs and organ systems, which places them in the group of potential pharmacological agents useful in various clinical entities. Their action as neurosteroids is especially interesting due to potential neuroprotective, pro-cognitive, anxiolytic, and antidepressant effects. Evidence from clinical studies supports the use of DHEA in hypoadrenal individuals and in treating depression and associated cognitive disorders. However, there is also an increasing trend of recreational DHEA misuse in healthy people, as it is classified as a dietary supplement in some countries. This article aims to provide a critical review regarding the biological and pharmacological effects of DHEA, its mechanism of action, and potential therapeutic use, especially in CNS disorders.

RESUMO

BACKGROUND AND OBJECTIVE: Although many trials have evaluated the use of dehydroepiandrosterone to improve outcomes in poor responders undergoing assisted reproductive technology treatment, evidence supporting this approach is controversial. We aimed to conduct a systematic review and meta-analysis of existing published data to further elucidate and supplement the use of Dehydroepiandrosterone (DHEA) to improve the effectiveness of vitro fertilization in patients with diminished ovarian reserve or adverse ovarian reactions. METHODS: PubMed, Embase, Cochrane Library, and the Web of Science databases were searched through December 2020. Oocyte yield, metaphase II oocytes, fertilized oocytes, top-quality embryos, clinical pregnancy rate, ongoing pregnancy rate, and live birth rate were analyzed as relative outcomes. Meta-analysis was performed and fitted to both fixed-effects models and random-effects models. RESULTS: Eight prospective randomized controlled studies, five prospective case-control studies, and three retrospective cohort studies were conducted with a total of 1998 participants. Meta-analyses of these studies showed a significantly higher number of oocytes retrieved (WMD 1.09, 95% CI 0.38 to 1.80), metaphase II oocytes (WMD 0.78, 95% CI 0.16 to 1.40), fertilized oocytes (WMD 0.84, 95% CI 0.42 to 1.26), top-quality embryos (WMD 0.60, 95% CI 0.34 to 0.86), clinical pregnancy rate (RR 1.35, 95% CI 1.13 to 1.61), and ongoing pregnancy rate (RR 1.82, 95% CI 1.34 to 2.46), although there was no difference in live birth rate (RR 1.35, 95% CI 0.94 to 1.94) in the DHEA supplementation groups compared with that in the control groups. CONCLUSION: Oral DHEA supplementation appears to improve some IVF outcomes. On the basis of this limited evidence, we conclude that further studies are required to provide sufficient data.

RESUMO

INTRODUCTION: Genitourinary syndrome of menopause is caused by climacteric estrogens drop and leads to bothersome and progressive genital and urinary symptoms. Considering the high frequency in the population and the impact on quality of life, it is crucial to find a safe and effective treatment. Pharmacological therapies aim to modulate the hormonal system and reverse tissue changes due to hypoestrogenism and consequently the symptoms. AREAS COVERED: We analyzed the scientific evidence concerning the main pharmacological treatments, which include systemic and topical estrogens, prasterone and ospemifene. This literature review focused on recent safety and efficacy findings in an attempt to identify the best treatment choice for each individual patient. EXPERT OPINION: There are encouraging data regarding the efficacy of all currently available pharmacological options and concerning their short and long-term safety. There are still doubts regarding best treatment choice for oncological high-risk population, in particular for breast cancer survivors, and some issues relative to patients' poor compliance and treatment adherence. For these reasons further studies need to be conducted with a patient-tailored focus.

RESUMO

Pulmonary hypertension is a group of disorders characterized by elevated mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance. To test our hypothesis that combining two drugs useful in experimental pulmonary hypertension, statins and dehydroepiandrosterone sulfate (DHEA S), is more effective than either agent alone, we induced pulmonary hypertension in adult male rats by exposing them to hypoxia (10%O2) for 3 weeks. We treated them with simvastatin (60 mg/l) and DHEA S (100 mg/l) in drinking water, either alone or in combination. Both simvastatin and DHEA S reduced mPAP (froma mean±s.d. of 34.4±4.4 to 27.6±5.9 and 26.7±4.8 mmHg, respectively), yet their combination was not more effective (26.7±7.9 mmHg). Differences in the degree of oxidative stress (indicated by malondialdehydeplasma concentration),the rate of superoxide production (electron paramagnetic resonance), or blood nitric oxide levels (chemiluminescence) did not explain the lack of additivity of the effect of DHEA S and simvastatin on pulmonary hypertension. We propose that the main mechanism of both drugs on pulmonary hypertension could be their inhibitory effect on 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase, which could explain their lack of additivity.
