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

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

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

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

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

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

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: 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

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

PURPOSE: Limited treatment options are currently available for glioblastoma (GBM), an extremely lethal type of brain cancer. For a variety of tumor types, bioenergetic deprivation through inhibition of cancer-specific metabolic pathways has proven to be an effective therapeutic strategy. Here, we evaluated the therapeutic effects and underlying mechanisms of dual inhibition of carnitine palmitoyltransferase 1A (CPT1A) and glucose-6-phosphate dehydrogenase (G6PD) critical for fatty acid oxidation (FAO) and the pentose phosphate pathway (PPP), respectively, against GBM tumorspheres (TSs). METHODS: Therapeutic efficacy against GBM TSs was determined by assessing cell viability, neurosphere formation, and 3D invasion. Liquid chromatography-mass spectrometry (LC-MS) and RNA sequencing were employed for metabolite and gene expression profiling, respectively. Anticancer efficacy in vivo was examined using an orthotopic xenograft model. RESULTS: CPT1A and G6PD were highly expressed in GBM tumor tissues. Notably, siRNA-mediated knockdown of both genes led to reduced viability, ATP levels, and expression of genes associated with stemness and invasiveness. Similar results were obtained upon combined treatment with etomoxir and dehydroepiandrosterone (DHEA). Transcriptome analyses further confirmed these results. Data from LC-MS analysis showed that this treatment regimen induced a considerable reduction in the levels of metabolites associated with the TCA cycle and PPP. Additionally, the combination of etomoxir and DHEA inhibited tumor growth and extended survival in orthotopic xenograft model mice. CONCLUSION: Our collective findings support the utility of dual suppression of CPT1A and G6PD with selective inhibitors, etomoxir and DHEA, as an efficacious therapeutic approach for GBM.

RESUMO

Intravaginal dehydroepiandrosterone (DHEA) is a locally metabolised estrogen and androgen precursor, licensed in 2018 in the EU for moderate to severe vulvovaginal atrophy in postmenopausal women. A literature search revealed four original trials suitable for appraisal, three evaluating change in dyspareunia or dryness as a primary outcome, one evaluated safety as a primary outcome. In two trials of 255 and 558 women without cancer, the benefit of placebo (nightly vaginal suppositories with a lipophilic base) was a 0.9 and 1 point reduction in dyspareunia as measured on a 3 point scale, an unvalidated outcome measure. With nightly DHEA, dyspareunia was reduced by an additional 0.4 points compared to placebo. When 464 women with gynaecological cancer were randomised, those using nightly plain moisturiser gel reported a reduction of 'most bothersome symptom' (either dyspareunia or dryness) of 1.5 points on a 3 point scale. Those using nightly DHEA reported an additional symptom reduction of 0.3 points. This is also an unvalidated outcome measure. Data evaluating the efficacy of DHEA over placebo is unconvincing and based on unvalidated primary outcome measures that also do not reflect the complex psycho-sexual and socio-cultural components of genitourinary menopausal symptoms. The efficacy and safety data excluded women taking systemic HRT, applies to postmenopausal, not perimenopausal, women and had relatively short follow up. It is important further independent trials use sophisticated and validated assessment tools to better establish the efficacy, safety and cost effectiveness of intravaginal DHEA in clinically representative groups of women before being routinely prescribed.

RESUMO

BACKGROUND: Predicting viral suppression early is crucial to improving treatment outcomes among people living with HIV/AIDS (PLWH) in clinics. Viral suppression is affected by stress, making stress indicators a potential predictive factor. Most of previous studies used the self-report questionnaire as stress indicators, but there were great drawbacks due to its subjective. In contrast, end products of neuroendocrine systems such as hypothalamic-pituitaryadrenal (HPA) and hypothalamic-pituitary-gonadal (HPG) axes and endogenous cannabinoid system (ECS) that involved in regulating stress as objective stress indicators are urgently needed to predict viral suppression. Therefore, this study aimed to investigate whether neuroendocrine indictors can strongly predict viral suppression among PLWH in China. METHODS: This cross-sectional study recruited 1198 PLWH on antiretroviral therapy (ART) in Guangxi, China. The concentrations of steroids (i.e., cortisol, cortisone, dehydroepiandrosterone, testosterone and progesterone) and endocannabinoids (i.e., N-arachidonoyl-ethanolamine and 1-arachidonyl glycerol) in hair were quantitated using the LC-APCI+-MS/MS method. To screen biomarkers that were used to predict viral suppression, association between hair biomarkers and viral suppression was examined by Mann-Whitney U test and partial correlation analyses. Receiver operating characteristic (ROC) curves and binary logistic regression based on the optimal classification threshold determined with ROC curves were used to estimate the prediction effects of the screened biomarkers on viral suppression (HIV-1 RNA < 200 copies/mL). RESULTS: Hair levels of dehydroepiandrosterone (DHEA), and N-arachidonoyl-ethanolamine (AEA), and the cortisol to DHEA ratio exhibited significant intergroup differences (ps < 0.05) and were correlated with HIV viral load (ps < 0.05). Hair DHEA concentrations strongly predicted viral suppression, showing good classification performance (area under the ROC curve = 0.651, p < 0.01) and strong predictive utility (adjusted odd ratio = 2.324, 95 % confidence interval = 1.211-4.899, p < 0.05) with an optimal threshold of 10.5 pg/mg. A hair AEA concentration of 2.4 pg/mg was the optimal threshold for predicting viral suppression based on good classification performance (area under the ROC curve = 0.598, p < 0.05) and predictive power (adjusted odd ratio = 2.124, 95 % confidence interval = 1.045-4.244, p < 0.05). In hair levels of cortisol to DHEA, viral suppression was observed to be highly predictive, with a threshold of 10.5 pg/mg being optimal for classification (area under the ROC curve = 0.624, p < 0.05) and prediction (adjusted odd ratio = 0.421, 95 % confidence interval = 0.201-0.785, p < 0.05). CONCLUSION: Hair levels of DHEA, and AEA and the cortisol to DHEA ratio were screened and verified to have significant predictive power with optimal thresholds for predicting viral suppression in a large-scale cohort. The data may provide new insights into predictors of successful virological outcomes and inform public health intervention and clinical practice to assist PLWH in achieving and sustaining viral suppression.

RESUMO

Androgen exposure may be an important factor in promoting the development of polycystic ovary syndrome (PCOS) and disease progression. Bushen Huoxue Formula (BHF), a traditional Chinese medicine, is prescribed in clinical settings as a PCOS remedy, albeit with unclear pharmacological effects on granulosa cells. The present research explores potentially advantageous BHF impacts and whereby BHF alleviates dehydroepiandrosterone (DHEA)-induced inflammation and endocrine disruption. Six chemical components in BHF were identified and fingerprint analysis showed good reproducibility. Using a human granulosa cell line (KGN), BHF effects on cell viability, secretion of steroidogenic and inflammatory factors were evaluated and TLR4/NF-κB pathway expression was examined. Our results demonstrate that BHF treatment of KGN cells in a DHEA-induced inflammatory state led to increased cell viability, decreased testosterone and estradiol production, and decreased CYP19A1 and HSD3B2 mRNA expression. Further experiments revealed that BHF inhibited the expression of pro-inflammatory cytokines and considerably hindered up-regulation in protein levels of TLR4, MyD88, and TRAF6, while inhibiting the activation of NF-κB and phosphorylation of IκBα. Collectively, BHF administration protected granulosa cells from DHEA-induced injuries through down-regulating pro-inflammatory cytokines and blocking the pathway of TLR4/NF-κB. Therefore, BHF hold promise as a therapeutic formulation for preventing androgen induced PCOS.

RESUMO

BACKGROUND: The electromagnetic fields (EMFs) emitted by the technologies affect the homeostatic systems (nervous, endocrine, and immune systems) and consequently the health. In a previous work, we observed that men and women, after 2 months of using a bed with a registered HOGO system, that prevents and drain EMFs, improved their immunity, redox and inflammatory states and rejuvenated their rate of aging or biological age. Since, EMFs can act as a chronic stressor stimulus, and affect the sleep quality. The objective of this work was to study in men and women (23-73 years old) the effect of sleeping for 2 months on that bed in the blood concentrations of several hormones related to stress response and sleep quality as well as to corroborate the rejuvenation of their biological age. METHODS: In 18 men and women, plasma concentration of cortisol, dehydroepiandrosterone (DHEA), catecholamines (epinephrine, norepinephrine and dopamine), serotonin, oxytocin and melatonin were analyzed before and after 2 months of using the HOGO beds. A group of 10 people was used as placebo control. In another cohort of 25 men (20 experimental and 5 placebo), the effects of rest on the HOGO system on the concentration of cortisol and testosterone in plasma were studied. In all these volunteers, the biological age was analyzed using the Immunity Clock model. RESULTS: There is a significant increase in plasma concentration of DHEA, norepinephrine, serotonin, oxytocin, and melatonin as well as in testosterone, after resting for 2 months in that bed with the EMFs avoiding system. In addition, decreases in Cortisol/DHEA and Testosterone/cortisol ratio and plasma dopamine concentration were observed. No differences were found in placebo groups. In all participants that slept on HOGO beds, the biological age was reduced. CONCLUSIONS: Sleeping in a bed that isolates from EMFs and drain them can be a possible strategy to improve the secretion of hormones related to a better response to stress and sleep quality, which means a better endocrine system, and consequently better homeostasis and maintenance of health. This fact was confirmed with the slowdown in the rate of aging checked with a rejuvenation of the biological age.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Dingkun Pill (DKP), a traditional Chinese medicine prescription, was modified from Bujing decoction and Xusijiangsheng pill by the imperial physician in the Qing dynasty (1700' s). It was believed to treat various gynecological diseases by nourishing qi and blood. Accumulating evidence indicates that it is effective in treating polycystic ovary syndrome (PCOS). However, the therapeutic efficacy and mechanism of action DKP against PCOS need to be further elucidated. AIM OF THE STUDY: To investigate the therapeutic effect and action mechanism of DKP against PCOS using an integrated approach of metabolomics and network pharmacology. MATERIALS AND METHODS: The rat model of PCOS was established by dehydroepiandrosterone. An integrated metabolomics and network pharmacology strategy was applied to systemically clarify the mechanism of DKP against PCOS. Theca cells were prepared to evaluate the effect of DKP and its ingredients on testosterone synthesis in vitro. RESULTS: The pharmacological experiments demonstrated that DKP could effectively convert the disordered estrous cyclicity, decrease the level of testosterone and the luteinizing hormone/follicle stimulating hormone ratio, and inhibit abnormal follicle formation in PCOS rats. By metabolomics analysis, 164 serum endogenous differential metabolites and 172 urine endogenous differential metabolites were tentatively identified. Steroid hormone biosynthesis and ovarian steroidogenesis were the most significantly impacted pathways. Based on network pharmacology and metabolomics studies, the ingredient-target-pathway network of DKP in the treatment of PCOS was constructed. Among the 10 key targets, CYP17A1, CYP19A1, STS, AR, ESR1, and MYC were closely involved in ovarian androgen synthesis. In theca cell-based assay of testosterone synthesis, DKP and its two active compounds (ligustilide and picrocrocin) showed inhibitory effects. CONCLUSION: DKP effectively improved symptoms in rats with dehydroepiandrosterone-induced PCOS. The mechanism of DKP in the treatment of PCOS is related to the CYP17A1 enzyme required for androgen synthesis.

RESUMO

Patients using nutraceuticals represent a diverse patient population with a keen potential interest and/or adherence to healthy lifestyle changes. BPH nutraceuticals, including saw palmetto were as safe, but not more effective than placebo in the STEP and CAMUS clinical trials, but another high-quality saw palmetto product could be tested in a phase 3 trial. Several other BPH supplements need more recent robust clinical data, environmental oversight, or safety data. ED supplements, including Panax ginseng, and the notable nitric oxide (NO) enhancing amino acids arginine and citrulline have positive preliminary short-term efficacy data with and without PDE-5 inhibitors, but herbal quality control (QC) or safety signals with some of these agents in specific patient populations need to be resolved. "Less is more" should be the current mantra in the prostate cancer milieu, and potentially in some men with male infertility based on the FAZST trial because it is plausible some antioxidants are exhibiting prooxidant activity in some settings. Some prescription anthelmintic medications are being studied, others are being purchased over-the-counter (OTC), but their preliminary safety and efficacy against cancer have been concerning and questionable. In fairness, ongoing additional objective clinical trial data should become available soon, especially with mebendazole. DHEA or DHEA enhancing products have multiple concerns including HDL reductions, and their questionable use in men with BPH or prostate cancer based on the limited data. Some of these concerns should also be addressed in long-term robust clinical trials of prescription testosterone agents. Regardless, more attention should be directed toward heart-healthy lifestyle changes for most urologic men's health conditions, whether they are used in a preventive or synergistic setting with other acceptable clinical treatment options.

RESUMO

CONTEXT: The majority of women with Sheehan syndrome (SS) suffer from sexual dysfunction. Severe androgen deficiency is a major contributory factor. Dehydroepiandrosterone (DHEA) supplementation has been reported to have variable efficacious in improving female sexual dysfunction (FSD) in several trials but studies using DHEA in SS are not available. OBJECTIVE: We aimed to study the use of DHEA supplementation in patients with SS. METHODS: In this crossover trial, 28 participants with SS (age 39.7 ±â€…8.6 years) were divided into 2 groups (using block randomization) who received DHEA supplements (25 mg twice daily) or matched placebo sequentially for 3 months each. Female Sexual Functioning Index (FSFI) score and serum DHEA sulfate (DHEAS) were measured at baseline and after completion of each phase. Glycemic parameters, lipid profile, and liver enzymes were also measured to assess metabolic side effects. RESULTS: There was significant improvement in FSFI score from baseline to end of the study in the DHEA group compared with the placebo group (P = 0.006). Mean FSFI score and most of the individual domains of female sexual dysfunction (FSD) improved with DHEA significantly in both groups (P = 0.001 for each group with DHEA). In those who received DHEA first followed by placebo, FSFI declined significantly after placebo (P = 0.041) but remained at an acceptable level of sexual functioning. Serum DHEAS increased significantly with DHEA treatment. No significant changes in glycemic index, lipid profile, and liver enzymes were noted with DHEA treatment. CONCLUSION: A short duration of DHEA supplementation in women with SS with FSD is efficacious and safe.

RESUMO

IMPORTANCE: Cancer and its treatment negatively affect female sexual health and function. The prevalence of female sexual dysfunction after cancer is between 33% and 43%. Numerous studies have addressed treatment options for sexual dysfunction in women with cancer, but it still remains a challenge to select the most efficacious option for patients. OBJECTIVE: To compile and appraise recent evidence of any interventions for managing sexual dysfunction in female cancer survivors. EVIDENCE REVIEW: A literature search of the electronic databases MEDLINE, EMBASE, PsycINFO, and Cochrane Central Register of Controlled Trials (January 2011 to February 2021) was conducted using general search terms of "women", "cancer", "intervention", "sexual dysfunction". We included randomized controlled trials (RCTs) and uncontrolled before-after studies that evaluated the efficacy of intervention for female sexual dysfunction in women with history of cancer. Methodological quality of studies was assessed using Risk of Bias (RoB) 2.0 for RCTs and National Institutes of Health (NIH) assessment tools for uncontrolled before-after studies. FINDINGS: Thirty-six studies were included for qualitative synthesis (14 RCTs (n = 1284), 17 uncontrolled trials (n = 589), and 5 cohort studies (n = 497). Only four studies were at low risk of bias. Topical interventions (vaginal gels or creams) were able to alleviate vaginal dryness and dyspareunia, with intravaginal dehydroepiandrosterone (DHEA) (6.5 mg) gel showing evidence of improved sexual function. Evidence for estriol-lactobacilli vaginal tablets was unreliable due to a small-scale study. Psychoeducational therapy (internet-based cognitive behavioral therapy [CBT]) studies typically were at high risk of bias, but all displayed significant improvements of sexual function. Both laser therapy (fractional CO2 and erbium) and multimodal approach studies were at concerning risk of bias, although suggesting beneficial effects on sexual function. CONCLUSIONS AND RELEVANCE: The most reliable evidence for improvement was from a study of DHEA vaginal gel, but in general, gels or creams were useful in reducing dyspareunia. Pharmacological, psychoeducational, laser therapy, and multimodal approaches demonstrated potential in managing cancer-related sexual issues, but most were small in size (10-70 participants), with moderate to high risk of bias. Therefore, large-scale, double-blind, RCTs with long-period follow-up, and at low risk of bias are needed to show efficacy for these interventions.

RESUMO

Resistance to doxorubicin (DOX) remains a big challenge to breast cancer treatment especially for triple negative breast cancer (TNBC). Our previous study revealed that the antioxidant system plays an important role in conferring metastasis derived DOX resistance. In this study, we used two-dimensional difference gel electrophoresis (2D-DIGE) proteomics to compare the expression profiles of two generations of TNBC cell lines which have increased metastatic ability in nude mice and exhibited resistance to DOX. Through careful analyses, one antioxidant protein: glucose-6-phosphate dehydrogenase (G6PD) was identified with 3.2-fold higher level in metastatic/DOX-resistant 231-M1 than its parental 231-C3 cells. Analyses of clinical data showed that TNBC patients with higher G6PD levels exhibited lower overall survival than patients with lower G6PD level. Reducing G6PD expression by siRNA or inhibiting its activity with dehydroepiandrosterone (DHEA) significantly increased DOX's cytotoxicity in both cell lines. Importantly, inhibiting G6PD's activity with DHEA dramatically increased the apoptotic rate of 1.25 µM DOX from 2% to 54%. Our results suggest that high level of G6PD can help TNBC to resist DOX-induced oxidative stress. Thus, inhibiting G6PD shall be a good strategy to treat DOX-resistant TNBC.
