Comparison of resumption of ovulation after cessation of oral contraceptives and medroxyprogesterone acetate in women with polycystic ovary syndrome. Gynecol Endocrinol 2024; 40:2309349. [PMID: 38306179 DOI: 10.1080/09513590.2024.2309349] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Accepted: 01/17/2024] [Indexed: 02/04/2024] Open
Abstract
OBJECTIVE Both oral contraceptive pills (OCPs) and cyclic medroxyprogesterone acetate (MPA) are widely used to control menstrual abnormalities in women with polycystic ovary syndrome (PCOS). We aimed to evaluate the chance of ovulation resumption after cessation of OCPs and MPA in women with PCOS. METHODS A retrospective study was conducted of women with PCOS who were treated with OCPs or cyclic MPA from September 2015 to March 2019. After cessation of medication, ovulation was assessed using basal body temperature and/or measurement of serum progesterone. The odds ratio for ovulation resumption was assessed with multivariable logistic regression. Additionally, doubly robust analysis was performed with inverse-probability-weighted analysis and regression adjustment based on the covariate balancing propensity score to adjust for the effect of covariates on the treatment assignment. RESULTS Among 272 women with PCOS, 136 were prescribed OCPs and 136 were prescribed cyclic MPA. Ovulation resumed in 18.4% of women (n = 25) after cessation of MPA and in 24.3% of women (n = 33) after cessation of OCPs. The odds of ovulation resumption in MPA users were comparable with those in OCP users (adjusted odds ratio (aOR) 1.00, 95% confidence interval (CI) 0.89-1.12). After multiple imputation due to missing values, the results did not change substantially (aOR 0.99, 95% CI 0.89-1.10). CONCLUSIONS Among women with PCOS, MPA users have a similar chance of ovulation resumption as OCP users after cessation of medication. Cyclic MPA can be a good alternative to OCPs in women for whom OCPs are contraindicated or who decline to take OCPs.

The impact of androgen levels on serum metabolic profiles in patients with polycystic ovary syndrome. Gynecol Endocrinol 2024; 40:2352136. [PMID: 38733359 DOI: 10.1080/09513590.2024.2352136] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Accepted: 04/24/2024] [Indexed: 05/13/2024] Open
Abstract
OBJECTIVE This study aimed to investigate the impact of serum androgen levels on metabolic profiles in patients with polycystic ovary syndrome (PCOS). METHODS We included 216 patients with PCOS and 216 healthy individuals selected as the control group. According to the measured serum androgen levels, patients with PCOS were divided into the hyperandrogenism group and non-hyperandrogenism group. Clinical metabolic indicators were assessed and compared between the two groups. Additionally, we assessed the correlation between androgen levels and clinical metabolic indicators. RESULTS The body mass index, waist-to-hip ratio, mF-G score, and acne score, as well as T, LH, LSH/FSH, FPG, Cr, UA, TG, TC, and LDL-C levels were significantly higher in the PCOS group than in the control group. The incidence of hyperandrogenism and clinical hyperandrogenism in the PCOS group was significantly higher than that in the control group. Regarding clinical hyperandrogenism, hirsutism, acne, and acanthosis nigricans were significantly more common in the PCOS group than in the control group. Serum androgen levels were significantly correlated with the mF-G score, acne score, FSH, glucose concentration at 30 min, glucose concentration at 60 min, glucose concentration at 120 min, FINS, N120, HOMA-IR, HbA1c, AUCG, UA, TG, and hHDL-Clevels. CONCLUSION Elevated serum androgen levels are commonly observed in patients with PCOS and are associated with multiple metabolic abnormalities. Therefore, it is recommended to regularly monitor glucose and lipid metabolism-related indicators in patients with PCOS who have elevated androgen levels.

Therapeutic potential of acarbose in ameliorating the metabolic and endocrinological complications of polycystic ovarian syndrome: a review. Curr Med Res Opin 2024:1-29. [PMID: 38771729 DOI: 10.1080/03007995.2024.2358237] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Accepted: 05/17/2024] [Indexed: 05/23/2024]
Abstract
Polycystic ovarian syndrome is a perplexed condition addressing endocrinal, cardiometabolic and gynaecological issues. It affects women of adolescent age and is drastically increasing in the Indo-Asian ethnicity over the recent years. According to Rotterdam criteria, PCOS is characterized by clinical or biochemical excess androgen and polycystic ovarian morphology; however, it has been established in the recent years that PCOS exacerbates to further serious metabolic conditions on the long term. This is a narrative literature review and not systematic review and is based on PubMed searches with relevant keywords "Polycystic ovarian syndrome AND acarbose OR metformin OR myoinositol; PCOS AND metabolic syndrome OR cardiovascular disease OR menstrual irregularity OR infertility OR chronic anovulation OR clinical hyperandrogenism" used in the title and are limited to articles published in English language with no time limits. A prominent aspect of PCOS is hyperandrogenaemia and hyperinsulinemia. About 50-70% of afflicted women have compensatory hyperinsulinemia and close to one tierce suffer from anovulation and infertility. Insulin resistance leads to metabolic complications and works with luteinizing hormone in increasing the ovarian androgen production. This excess androgen leads to clinical manifestations, irregular menstrual cycles and infertility. There isn't an entire cure, only the symptomatic clinical factors are considered rather than focusing on the underlying long-term complications. Therefore, the article focuses on a potent alpha glucosidase inhibitor, acarbose which suppresses the post meal glucose and insulin by delaying the absorption of complex carbs. It exhibits cardio-metabolic and hormonal benefits and is well tolerable in the south asian population. This review highlights the safety, effectiveness of acarbose in ameliorating the long-term complications of PCOS.

Metabolic landscape and pathogenic insights: a comprehensive analysis of high ovarian response in infertile women undergoing in vitro fertilization. J Ovarian Res 2024; 17:105. [PMID: 38760835 PMCID: PMC11102248 DOI: 10.1186/s13048-024-01411-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Accepted: 04/10/2024] [Indexed: 05/19/2024] Open
Abstract
BACKGROUND In the realm of assisted reproduction, a subset of infertile patients demonstrates high ovarian response following controlled ovarian stimulation (COS), with approximately 29.7% facing the risk of Ovarian Hyperstimulation Syndrome (OHSS). Management of OHSS risk often necessitates embryo transfer cancellation, leading to delayed prospects of successful pregnancy and significant psychological distress. Regrettably, these patients have received limited research attention, particularly regarding their metabolic profile. In this study, we aim to utilize gas chromatography-mass spectrometry (GC-MS) to reveal these patients' unique serum metabolic profiles and provide insights into the disease's pathogenesis. METHODS We categorized 145 infertile women into two main groups: the CON infertility group from tubal infertility patients and the Polycystic Ovary Syndrome (PCOS) infertility group. Within these groups, we further subdivided them into four categories: patients with normal ovarian response (CON-NOR group), patients with high ovarian response and at risk for OHSS (CON-HOR group) within the CON group, as well as patients with normal ovarian response (PCOS-NOR group) and patients with high ovarian response and at risk for OHSS (PCOS-HOR group) within the PCOS group. Serum metabolic profiles were analyzed using GC-MS. The risk criteria for OHSS were: the number of developing follicles > 20, peak Estradiol (E2) > 4000pg/mL, and Anti-Müllerian Hormone (AMH) levels > 4.5ng/mL. RESULTS The serum metabolomics analysis revealed four different metabolites within the CON group and 14 within the PCOS group. Remarkably, 10-pentadecenoic acid emerged as a discernible risk metabolite for the CON-HOR, also found to be a differential metabolite between CON-NOR and PCOS groups. cysteine and 5-methoxytryptamine were also identified as risk metabolites for the PCOS-HOR. Furthermore, KEGG analysis unveiled significant enrichment of the aminoacyl-tRNA biosynthesis pathway among the metabolites differing between PCOS-NOR and PCOS-HOR. CONCLUSION Our study highlights significant metabolite differences between patients with normal ovarian response and those with high ovarian response and at risk for OHSS within both the tubal infertility control group and PCOS infertility group. Importantly, we observe metabolic similarities between patients with PCOS and those with a high ovarian response but without PCOS, suggesting potential parallels in their underlying causes.

Effect of SGLT2 Inhibitors on Improving Glucolipid Metabolism and Reproductive Hormone Status in Overweight/Obese Women with PCOS: A Systematic Review and Meta-Analysis. Reprod Sci 2024; 31:1190-1203. [PMID: 38057530 DOI: 10.1007/s43032-023-01415-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Accepted: 11/20/2023] [Indexed: 12/08/2023]
Abstract
BACKGROUND Obesity, insulin resistance, and hyperandrogenemia are commonly seen in women with polycystic ovary syndrome (PCOS), and these three conditions form a vicious cycle leading to reproductive and metabolic abnormalities. Metformin improves the symptoms of PCOS by increasing insulin sensitivity but is not therapeutically optimal. Recent studies have reported that sodium-glucose co-transporter protein receptor inhibitors improve insulin resistance and reduce the weight of patients with PCOS. We performed a meta-analysis to assess the influence of sodium-glucose co-transporter protein-2 (SGLT2) inhibitors on anthropometric, glycolipid metabolism and reproductive outcomes after therapy of overweight/obese women with PCOS. METHODS We searched the relevant literature published up to April 2023. Information on the effect of SGLT2 inhibitors on overweight/obese patients with PCOS was extracted independently by two reviewers. Review Manager 5.3 was used for meta-analysis. RESULTS Five randomized controlled trials that met our criteria were retrieved. Our meta-analysis demonstrated that in overweight/obese patients with PCOS, SGLT2 inhibitors treatment was significantly superior to metformin treatment in terms of reducing body weight (P = 0.02, I2 = 36%), decreasing dehydroepiandrosterone sulfate concentrations [SMD = -0.42, 95% CI (-0.76, -0.07), I2 = 22%, P = 0.02], and reducing the incidence of nausea [RR = 0.35, 95% CI (0.21, 0.60), I2 = 71%, P = 0.0001]. CONCLUSIONS SGLT2 inhibitors are a possible alternative therapy for treating overweight/obese women with PCOS who do not respond favorably to metformin treatment. However, further large randomized controlled trials and cost-effectiveness analyses are warranted to guide the implementation of SGLT2 inhibitors treatment in this population.

Ensuring quality in 17OHP mass spectrometry measurement: an international study assessing isomeric steroid interference. Clin Chem Lab Med 2024; 62:911-918. [PMID: 38063179 DOI: 10.1515/cclm-2023-0864] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Accepted: 11/26/2023] [Indexed: 04/05/2024]
Abstract
OBJECTIVES Interference from isomeric steroids is a potential cause of disparity between mass spectrometry-based 17-hydroxyprogesterone (17OHP) results. We aimed to assess the proficiency of mass spectrometry laboratories to report 17OHP in the presence of known isomeric steroids. METHODS A series of five samples were prepared using a previously demonstrated commutable approach. These samples included a control (spiked to 15.0 nmol/L 17OHP) and four challenge samples further enriched with equimolar concentrations of 17OHP isomers (11α-hydroxyprogesterone, 11β-hydroxyprogesterone, 16α-hydroxyprogesterone or 21-hydroxyprogesterone). These samples were distributed to 38 participating laboratories that reported serum 17OHP results using mass spectrometry in two external quality assurance programs. The result for each challenge sample was compared to the control sample submitted by each participant. RESULTS Twenty-six laboratories (68 % of distribution) across three continents returned results. Twenty-five laboratories used liquid chromatography-tandem mass spectrometry (LC-MS/MS), and one used gas chromatography-tandem mass spectrometry to measure 17OHP. The all-method median of the control sample was 14.3 nmol/L, ranging from 12.4 to 17.6 nmol/L. One laboratory had results that approached the lower limit of tolerance (minus 17.7 % of the control sample), suggesting the isomeric steroid caused an irregular result. CONCLUSIONS Most participating laboratories demonstrated their ability to reliably measure 17OHP in the presence of the four clinically relevant isomeric steroids. The performance of the 12 (32 %) laboratories that did not engage in this activity remains unclear. We recommend that all laboratories offering LC-MS/MS analysis of 17OHP in serum, plasma, or dried bloodspots determine that the isomeric steroids are appropriately separated.

Abstract
Background To observe the basic metabolic characteristics of obese patients with polycystic ovarian syndrome (PCOS), and observe and compare the effect of laparoscopic sleeve gastrectomy and metformin treatment after 3 months. Methods In January to December 2018, the Second Hospital of Hebei Medical University selected 104 women who were classified as obese with a body mass index (BMI) of 28 kg/cm2 or higher and had PCOS. They were divided into obese PCOS group (53 cases) and obese non-PCOS group (51 cases). Results 1. There was no significant difference in waist circumference and WHR between patients who are obese with PCOS and patients who are obese without PCOS (P > 0.05). Obese PCOS patients were significantly higher in anti-Müllerian hormone (AMH), LH/FSH, T, FAI, homa-ir, triglyceride (TG), low density lipoprotein (LDL), Apo-B and uric acid than the group of non-PCOS patients who were obese. (P<0.05). The SHBG levels of obese patients with PCOS were obviously lower when contrasted with the levels in obese patients without PCOS (P < 0.05). 2. Body weight, BMI, INS, homa-ir and TG of obese PCOS patients were significantly decreased 3 months after laparoscopic sleeve gastrectomy compared with that before surgery (P < 0.05). After three months of medical treatment with metformin, the patients' homeostatic model assessment of insulin resistance (HOMA-IR) was obviously reduced when contrasted with the pre-treatment HOMA-IR levels (P < 0.05), and there was no significant difference in the improvement degree of homa-ir between the two groups (P > 0.05). Conclusions 1. Obese patients with PCOS demonstrated higher expression of AMH, LH/FSH, T, SHBG, and FAI when contrasted with the control group. Additionally, they experienced more severe insulin resistance and lipid metabolism disorders. 2. The weight and BMI of obese PCOS patients were significantly decreased after weight loss, while IR and blood lipid were significantly improved, while IR was improved in metformin group, and no significant discrepancy was observed in the degree of improvement of insulin resistance between both groups.

Hyperandrogenism and Cardiometabolic Risk in Pre- and Postmenopausal Women-What Is the Evidence? J Clin Endocrinol Metab 2024; 109:1202-1213.

Abstract
Hyperandrogenism in women, such as polycystic ovary syndrome, ovarian hyperthecosis, congenital adrenal hyperplasia, and androgen-secreting tumors, are all associated with increased prevalence of cardiovascular risk factors that include type 2 diabetes, hypertension, dyslipidemia, and metabolic syndrome. However, it is not clear whether this also implies enhanced risk of cardiovascular disease and mortality. Furthermore, the involvement of obesity and menopausal status for cardiometabolic risk in these women has not been elucidated. Based on the most recent systematic reviews and meta-analyses, this review summarizes the latest scientific evidence. To conclude, hyperandrogenism in premenopausal women is associated with enhanced prevalence of cardiovascular risk factors, as well as increased risk of cardiovascular disease and mortality, independently of body mass index. In contrast, elevated cardiovascular risk factors and increased risk of myocardial infarction and stroke in hyperandrogenic postmenopausal women are dependent on obesity. Furthermore, the overall risk of cardiovascular disease and coronary artery disease in hyperandrogenic postmenopausal women is similar to controls. The reason for a reduced cardiometabolic risk after menopause in hyperandrogenic women compared to nonhyperandrogenic women is not clear. It can be speculated that the difference in endocrine balance and metabolic status between women with and without hyperandrogenism might decrease after menopause because hyperandrogenism usually improves with age, whereas menopausal transition itself is associated with androgen dominance and abdominal obesity. Although we have gained increased knowledge about cardiometabolic risks in women with hyperandrogenism, it must be acknowledged that the quality of data is overall low. More research is needed, especially longer and larger follow-up studies in women with hyperandrogenism of different etiologies and phenotypes.

Inhibition of the glucocorticoid-activating enzyme 11β-hydroxysteroid dehydrogenase type 1 drives concurrent 11-oxygenated androgen excess. FASEB J 2024; 38:e23574. [PMID: 38551804 DOI: 10.1096/fj.202302131r] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Revised: 02/19/2024] [Accepted: 03/11/2024] [Indexed: 04/02/2024]
Abstract
Aldo-keto reductase 1C3 (AKR1C3) is a key enzyme in the activation of both classic and 11-oxygenated androgens. In adipose tissue, AKR1C3 is co-expressed with 11β-hydroxysteroid dehydrogenase type 1 (HSD11B1), which catalyzes not only the local activation of glucocorticoids but also the inactivation of 11-oxygenated androgens, and thus has the potential to counteract AKR1C3. Using a combination of in vitro assays and in silico modeling we show that HSD11B1 attenuates the biosynthesis of the potent 11-oxygenated androgen, 11-ketotestosterone (11KT), by AKR1C3. Employing ex vivo incubations of human female adipose tissue samples we show that inhibition of HSD11B1 results in the increased peripheral biosynthesis of 11KT. Moreover, circulating 11KT increased 2-3 fold in individuals with type 2 diabetes after receiving the selective oral HSD11B1 inhibitor AZD4017 for 35 days, thus confirming that HSD11B1 inhibition results in systemic increases in 11KT concentrations. Our findings show that HSD11B1 protects against excess 11KT production by adipose tissue, a finding of particular significance when considering the evidence for adverse metabolic effects of androgens in women. Therefore, when targeting glucocorticoid activation by HSD11B1 inhibitor treatment in women, the consequently increased generation of 11KT may offset beneficial effects of decreased glucocorticoid activation.

Abstract
Metformin is a synthetic biguanide used as an antidiabetic drug in type 2 diabetes mellitus, achieved by studying the bioactive metabolites of Galega officinalis L. It is also used off-label for various other diseases, such as subclinical diabetes, obesity, polycystic ovary syndrome, etc. In addition, metformin is proposed as an add-on therapy for several conditions, including autoimmune diseases, neurodegenerative diseases, and cancer. Although metformin has been used for many decades, it is still the subject of many pharmacodynamic and pharmacokinetic studies in light of its extensive use. Metformin acts at the mitochondrial level by inhibiting the respiratory chain, thus increasing the AMP/ATP ratio and, subsequently, activating the AMP-activated protein kinase. However, several other mechanisms have been proposed, including binding to presenilin enhancer 2, increasing GLP1 release, and modification of microRNA expression. Regarding its pharmacokinetics, after oral administration, metformin is absorbed, distributed, and eliminated, mainly through the renal route, using transporters for cationic solutes, since it exists as an ionic molecule at physiological pH. In this review, particular consideration has been paid to literature data from the last 10 years, deepening the study of clinical trials inherent to new uses of metformin, the differences in effectiveness and safety observed between the sexes, and the unwanted side effects. For this last objective, metformin safety was also evaluated using both VigiBase and EudraVigilance, respectively, the WHO and European databases of the reported adverse drug reactions, to assess the extent of metformin side effects in real-life use.

Traditional Chinese medicine formulae: A complementary method for the treatment of polycystic ovary syndrome. JOURNAL OF ETHNOPHARMACOLOGY 2024; 323:117698. [PMID: 38171464 DOI: 10.1016/j.jep.2023.117698] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 12/04/2023] [Accepted: 12/30/2023] [Indexed: 01/05/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Polycystic ovary syndrome (PCOS) is a prevalent female endocrine condition that significantly affects women of all age groups and is characterized by metabolic dysfunction. The efficacy of existing pharmaceutical interventions for the treatment of PCOS remains inadequate. With a rich history and cultural significance spanning thousands of years, Traditional Chinese Medicine (TCM) is extensively employed for treating a variety of ailments and can serve as a supplementary therapy for managing PCOS. Multiple clinical observations and laboratory tests have unequivocally demonstrated the substantial effectiveness and safety of TCM formulae in treating PCOS, and further investigations are currently in progress. AIM OF THE STUDY To summarize the TCM formulae commonly employed in the clinical management of PCOS, examine their therapeutic benefits, investigate their mechanism of action, active constituents, and establish the correlation between efficacy, mechanism of action, and active constituents. MATERIALS AND METHODS We conducted a comprehensive search on PubMed, Web of Science, and China national knowledge infrastructure (CNKI) using the following keywords: "Polycystic Ovary Syndrome", "Traditional Chinese Medicine Decoctions", "Traditional Chinese Medicine formulae", "Traditional Chinese Medicine", "Clinical Observation", "Mechanism", "Treatment", "Pharmacology", and various combinations of these terms. From January 1, 2006 until October 7, 2023, (inclusive). RESULTS This paper summarized the clinical effectiveness, mechanism of action, and active components of 8 TCM formulae for the treatment of PCOS. Our research indicates that TCM formulae can potentially treat PCOS by enhancing the levels of hyperandrogenism and other endocrine hormones, decreasing insulin resistance and hyperinsulinemia, and controlling chronic low-grade inflammation, among other modes of action. In addition, we found an association between epigenetics and TCM formulae for the treatment of PCOS. CONCLUSION TCM formulae have specific advantages in the treatment of Polycystic Ovary Syndrome (PCOS). They achieve therapeutic benefits by targeting several pathways and connections, attracting considerable interest and playing a vital role in the treatment of PCOS. TCM formulae can be used as an adjunctive therapy for the treatment of PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is the most widespread and diverse endocrine health issue affecting many adolescent-aged women globally. It is the most frequent illness in reproductive-aged women. According to the Rotterdam criteria, two out of three elements: oligo-anovulation, hyperandrogenism, and polycystic ovaries (defined as having at least one ovary with an ovarian volume > 10 mL and/or 12 or more follicles measuring 2 to 9 mm in diameter) are present in PCOS. Conducted studies show epigenetics, environmental toxins, stress, and food as external factors as well as inflammation, oxidative stress, hyperandrogenism, insulin resistance, and obesity as internal factors related to PCOS. Although a portion of the mechanism associated with the occurrence of PCOS has been identified, there is still much to learn about the exact etiology and pathophysiology. The main debate covers the best ways to diagnose and treat this disease in adolescents. Early detection is crucial because of the disease's long-term effects on metabolic and reproductive health. Before beginning treatment for this group of young women, a firm diagnosis may not be made. Various criteria are used to diagnose PCOS patients. A person with PCOS has a chance of developing several comorbidities and health effects. PCOS patients are at risk of cardiac diseases, metabolic syndromes, resistance to insulin, infertility, and many more. There are numerous medications available for PCOS therapy that need a methodical approach. However, changing one's lifestyle should come first. There is proof in the support of the usage of several medications for PCOS, including mucolytic agents, Hydroxymethylglutaryl-CoA (HMG-CoA) reductase inhibitors, gliptins (oral diabetic medication), glucose-like peptide-1 receptor analogues, glitazones, and sodium-glucose cotransporter protein-2 (SGLT2) inhibitors. A comprehensive, systematic, schematic therapy approach is crucial for the treatment of PCOS.

Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism, insulin resistance, and hepatic steatosis (HS). Because dietary essential amino acid (EAA) supplementation has been shown to decrease HS in various populations, this study's objective was to determine whether supplementation would decrease HS in PCOS. METHODS A randomized, double-blind, crossover, placebo-controlled trial was conducted in 21 adolescents with PCOS (BMI 37.3 ± 6.5 kg/m2, age 15.6 ± 1.3 years). Liver fat, very low-density lipoprotein (VLDL) lipogenesis, and triacylglycerol (TG) metabolism were measured following each 28-day phase of placebo or EAA. RESULTS Compared to placebo, EAA was associated with no difference in body weight (p = 0.673). Two markers of liver health improved: HS was lower (-0.8% absolute, -7.5% relative reduction, p = 0.013), as was plasma aspartate aminotransferase (AST) (-8%, p = 0.004). Plasma TG (-9%, p = 0.015) and VLDL-TG (-21%, p = 0.031) were reduced as well. VLDL-TG palmitate derived from lipogenesis was not different between the phases, nor was insulin sensitivity (p > 0.400 for both). Surprisingly, during the EAA phase, participants reported consuming fewer carbohydrates (p = 0.038) and total sugars (p = 0.046). CONCLUSIONS Similar to studies in older adults, short-term EAA supplementation in adolescents resulted in significantly lower liver fat, AST, and plasma lipids and thus may prove to be an effective treatment in this population. Additional research is needed to elucidate the mechanisms for these effects.

CPEB1 induces autophagy and promotes apoptosis in ovarian granulosa cells of polycystic ovary syndrome. Mol Reprod Dev 2024; 91:e23741. [PMID: 38616716 DOI: 10.1002/mrd.23741] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 03/07/2024] [Accepted: 03/18/2024] [Indexed: 04/16/2024]
Abstract
Inflammatory damage in ovarian granulosa cells (GCs) is a key mechanism in polycystic ovary syndrome (PCOS), cytoplasmic polyadenylation element binding protein-1 (CPEB1) is important in inflammatory regulation, however, its role in PCOS is unclear. We aim to research the mechanism of CPEB1 in ovarian GCs in PCOS using dehydroepiandrosterone (DHEA)-induced PCOS rat models and testosterone-incubated GC models. The pathophysiology in PCOS rats was analyzed. Quantitative-realtime-PCR, TUNEL, immunohistochemistry, and Western blot were applied for quantification. Additionally, cell counting kit-8, flow cytometry, immunofluorescence, Western blot, and Monodansylcadaverine staining were performed. We found that PCOS rat models exhibited a disrupted estrus cycle, elevated serum levels of testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH), increased LH/FSH ratio, and heightened ovarian index. Furthermore, reduced corpus luteum and increased follicular cysts were observed in ovarian tissue. In ovarian tissue, autophagy and apoptosis were activated and CPEB1 was overexpressed. In vitro, CPEB1 overexpression inhibited cell viability and sirtuin-1 (SIRT1), activated tumor necrosis factor-α, and interleukin-6 levels, as well as apoptosis and autophagy; however, CPEB1 knockdown had the opposite effect. In conclusion, overexpression of CPEB1 activated autophagy and apoptosis of ovarian GCs in PCOS.

Health benefits of combined oral contraceptives - a narrative review. EUR J CONTRACEP REPR 2024; 29:40-52. [PMID: 38426312 DOI: 10.1080/13625187.2024.2317295] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Accepted: 02/06/2024] [Indexed: 03/02/2024]
Abstract
PURPOSE This review presents an update of the non-contraceptive health benefits of the combined oral contraceptive pill. METHODS We conducted a literature search for (review) articles that discussed the health benefits of combined oral contraceptives (COCs), in the period from 1980 to 2023. RESULTS We identified 21 subjective and/or objective health benefits of COCs related to (i) the reproductive tract, (ii) non-gynaecological benign disorders and (iii) malignancies. Reproductive tract benefits are related to menstrual bleeding(including anaemia and toxic shock syndrome), dysmenorrhoea, migraine, premenstrual syndrome (PMS), ovarian cysts, Polycystic Ovary Syndrome (PCOS), androgen related symptoms, ectopic pregnancy, hypoestrogenism, endometriosis and adenomyosis, uterine fibroids and pelvic inflammatory disease (PID). Non-gynaecological benefits are related to benign breast disease, osteoporosis, rheumatoid arthritis, multiple sclerosis, asthma and porphyria. Health benefits of COCs related to cancer are lower risks of endometrial cancer, ovarian cancer and colorectal cancer. CONCLUSIONS The use of combined oral contraceptives is accompanied with a range of health benefits, to be balanced against its side-effects and risks. Several health benefits of COCs are a reason for non-contraceptive COC prescription.

Very low-calorie ketogenic diet (VLCKD): a therapeutic nutritional tool for acne? J Transl Med 2024; 22:322. [PMID: 38556870 PMCID: PMC10983624 DOI: 10.1186/s12967-024-05119-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2024] [Accepted: 03/20/2024] [Indexed: 04/02/2024] Open
Abstract
BACKGROUND Acne, a chronic inflammatory disease impacting the pilosebaceous unit, is influenced significantly by inflammation and oxidative stress, and is commonly associated with obesity. Similarly, obesity is also associated with increased inflammation and oxidation. The role of diet in acne remains inconclusive, but the very low-calorie ketogenic diet (VLCKD), known for weight loss and generating anti-inflammatory ketone bodies, presents promising potential. Despite this, the effects of VLCKD on acne remain underexplored. This study aimed to investigate the efficacy of a 45-day active phase of VLCKD in reducing the clinical severity of acne in young women with treatment-naïve moderate acne and grade I obesity. METHODS Thirty-one women with treatment-naïve moderate acne, grade I obesity (BMI 30.03-34.65 kg/m2), aged 18-30 years, meeting inclusion/exclusion criteria, and consenting to adhere to VLCKD were recruited. Baseline and post-intervention assessments included anthropometric measurements, body composition, phase angle (PhA), trimethylamine N-oxide (TMAO) levels, and reactive oxygen metabolite derivatives (dROMs) as markers of inflammation, dysbiosis, and oxidative stress, respectively. A comprehensive dermatological examination, incorporating the Global Acne Grading System (GAGS) and the Dermatology Life Quality Index (DLQI), was conducted for all women. RESULTS VLCKD resulted in general improvements in anthropometric and body composition parameters. Significantly, there were significant reductions in both the GAGS score (Δ%: - 31.46 ± 9.53, p < 0.001) and the DLQI score (Δ%: - 45.44 ± 24.02, p < 0.001) after the intervention. These improvements coincided with significant decreases in TMAO (p < 0.001) and dROMs (p < 0.001) levels and a significant increase in PhA (Δ%: + 8.60 ± 7.40, p < 0.001). Changes in the GAGS score positively correlated with changes in dROMs (p < 0.001) and negatively with PhA (p < 0.001) even after adjusting for Δ% FM. Changes in the DLQI score positively correlated with changes in dROMs (p < 0.001) and negatively with PhA (p < 0.001) even after adjustment for Δ% FM. CONCLUSION Given the side effects of drugs used for acne, there is an increasing need for safe, tolerable, and low-cost treatments that can be used for acne disease. The 45-day active phase of VLCKD demonstrated notable improvements in acne severity, and these improvements seemed to be attributable to the known antioxidant and anti-inflammatory effects of VLCKD.

Immune dysfunction mediated by the competitive endogenous RNA network in fetal side placental tissue of polycystic ovary syndrome. PLoS One 2024; 19:e0300461. [PMID: 38512862 PMCID: PMC10956758 DOI: 10.1371/journal.pone.0300461] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Accepted: 02/27/2024] [Indexed: 03/23/2024] Open
Abstract
Polycystic ovary syndrome (PCOS), a common endocrine and metabolic disorder affecting women in their reproductive years. Emerging evidence suggests that the maternal-fetal immune system is crucial for proper pregnancy. However, whether immune function is altered at the end of pregnancy in PCOS women and the underlying molecular mechanisms is currently unexplored. Herein, the basic maternal immune system was investigated (n = 136 in the control group; n = 103 in the PCOS group), and whole-transcriptome sequencing was carried out to quantify the mRNAs, miRNAs, and lncRNAs expression levels in fetal side placental tissue of women with PCOS. GO, KEGG, and GSEA analysis were employed for functional enrichment analysis. The process of identifying hub genes was conducted utilizing the protein-protein interaction network. CIBERSORT and Connectivity Map were deployed to determine immune cell infiltration and predict potential drugs, respectively. A network of mRNA-miRNA-lncRNA was constructed and then validated by qRT-PCR. First, red blood cell count, neutrophil count, lymphocyte count, hypersensitive C-reactive protein, and procalcitonin were significantly elevated, while placental growth factor was hindered in PCOS women. We identified 308 DEmRNAs, 77 DEmiRNAs, and 332 DElncRNAs in PCOS samples. Functional enrichment analysis revealed that there were significant changes observed in terms of the immune system, especially the chemokine pathway. Eight genes, including FOS, JUN, EGR1, CXCL10, CXCR1, CXCR2, CXCL11, and CXCL8, were considered as hub genes. Furthermore, the degree of infiltration of neutrophils was dramatically decreased in PCOS tissues. In total, 57 ceRNA events were finally obtained, and immune-related ceRNA networks were validated. Some potential drug candidates, such as enalapril and RS-100329, could have a function in PCOS therapy. This study represents the inaugural attempt to evaluate the immune system at the end of pregnancy and placental ceRNA networks in PCOS, indicating alterations in the chemokine pathway, which may impact fetal and placental growth, and provides new therapy targets.

Abstract
Hirsutism, unwanted terminal hair growth in androgen-dependent areas, is a common presentation to general paediatricians, dermatologists and endocrinologists. Polycystic ovarian syndrome is the most common cause but can be challenging to diagnose in young people due to the significant overlap of features with the healthy adolescent population. There are other rare, but important, causes to consider such as non-classic congenital adrenal hyperplasia and androgen-secreting tumours. Hirsutism carries a significant psychological burden for those living with it. This 15 min consultation piece describes the causes of hirsutism, introduces a novel assessment tool and suggests an approach to investigations and management, including signposting to psychological support.

Abstract
BACKGROUND Polycystic ovarian syndrome (PCOS) is a heterogeneous and complex reproductive endocrinological disease that could lead to infertility. There were many attempts to classify PCOS but it remains unclear whether there is a specific subgroup of PCOS that is associated with the best or worst reproductive outcomes of assisted reproductive techniques (ART). METHODS Infertile PCOS patients who underwent their first cycle of in vitro fertilization (IVF) in West China Second University Hospital, Sichuan University from January 2019 to December 2021 were included. Basic clinical and laboratory information of each individual were extracted. Unsupervised cluster analysis was performed. Controlled ovarian stimulation parameters and reproductive outcomes were collected and compared between the different clusters of PCOS. RESULTS Our analysis clustered women with PCOS into "reproductive", "metabolic", and "balanced" clusters based on nine traits. Reproductive group was characterized by high levels of testosterone (T), sex hormone-binding globulin (SHBG), follicular stimulation hormone (FSH), luteinizing hormone (LH), and anti-Müllerian hormone (AMH). Metabolic group was characterized by high levels of body mass index (BMI), fasting insulin, and fasting glucose. Balanced group was characterized by low levels of the aforementioned reproductive and metabolic parameters, except for SHBG. Compared with PCOS patients in reproductive and balanced clusters, those in metabolic cluster had lower rates of good quality day 3 embryo and blastocyst formation. Moreover, PCOS patients in the reproductive cluster had greater fresh embryo transfer (ET) cancelation rate and clinical pregnancy rate after fresh ET than metabolic cluster (odds ratio [OR] = 3.37, 95% confidence interval [CI]: 1.77-6.44, and OR = 6.19, 95% CI: 1.58-24.24, respectively). And compared with PCOS of metabolic cluster, PCOS of balanced cluster also had higher chance for fresh ET cancelation (OR = 2.83, 95% CI: 1.26-6.35). CONCLUSION Our study suggested that PCOS patients in metabolic cluster may be associated with adverse reproductive outcomes and might need individualized treatment and careful monitoring before and during ART.

Abstract
Background Polycystic Ovarian Syndrome (PCOS) is the most common genetic disorder of the endocrine gland among females during the age of reproduction with an estimated prevalence ranging from 2.2 % to 26 %. It is a typical reason for ovulatory infertility, menstrual dysfunction, and hirsutism. It is a condition in which ovarian cysts develop with a diameter of between two and nine millimeters on one or each ovaries and therefore there is an increase in the volume of one is larger than ten millimeters. Objective To analyze the effect of pilates on pain and regulation of the menstrual cycle in females with PCOS. Research methodology A single centered, quasi-experimental study, performed in Lovely Professional University, India on a total of 26 participants suffering from PCOS, based on inclusion and exclusion criteria. After a detailed assessment, the Pilates exercise protocol was given for 3 months i.e. 3 times per week. The readings for pain and regulation were taken at baseline, at the end of 1st, 2nd, and 3rd month using visual analog scale (VAS)and verbal multidimensional score sysem (VMSS). Results The result findings indicates suggested that there is significant change in the pain (Wilk's Lambda =.117, F(3,23) = 58.109, P < 0.05), variable during the menstruation in PCOS over the time of three months. The menstrual cycles were regularised and the cycle was shifted towards the normal parameters. The VMSS also shows changes that signify that Pilates is effective in PCOS complications. Conclusion This study concluded that Pilates is effective in reducing the pain in PCOS cases which improves the working ability of the females and also regulates the menstrual cycles which were irregular at the beginning of the treatment.

Abstract
OBJECTIVE Spironolactone (SPL) has been used to manage hyperandrogenic manifestations in women with polycystic ovary syndrome (PCOS), but data on the risk of hyperkalemia in this population are scarce. The aim of this study was to evaluate the incidence of hyperkalemia in women with PCOS using SPL in the long term. DESIGN Single-centre retrospective study. PATIENTS Inclusion and analysis of 98 treatment periods in 78 women with PCOS (20 of whom were duplicates, returning after treatment interruption for a mean of 38 months) who received SPL for a minimum of 12 months and had at least three measurements of potassium levels over time. MEASUREMENTS Clinical and hormonal profiles before and during SPL treatment. RESULTS Mean age was 29.1 (SD: 9.6) years, and body mass index was 32.2 (SD: 8.1) kg/m². Nine patients had diabetes, and 22 had prediabetes. SPL was used in combination with combined oral contraceptive pills in 55 participants and progestin-only pills/long-acting reversible contraception in 28; metformin was added in 35, and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers in 15. Median SPL dose was 100 (range: 50-150) mg. A total of 327 serum potassium measurements were obtained (84 pre-exposure and 243 postexposure). Four potassium measurements were above the reference range before exposure and 19 during exposure. All potassium measurements above the reference range during follow-up were classified as mild hyperkalemia (5.1-5.5 mEq/L). CONCLUSIONS The present findings suggest that women with PCOS, without kidney or heart disease, using SPL combined with hormonal contraception for managing clinical hyperandrogenism have a low incidence of hyperkalemia and well-tolerated minor adverse effects.

Abstract
Polycystic ovarian syndrome (PCOS) is a common endocrinological disorder affecting many adolescents and women of reproductive age worldwide. A diagnosis of PCOS in adolescence relies upon investigating each medical history independently and noting commonly associated symptoms, including obesity, insulin resistance, acne, menstrual abnormalities, and hirsutism. Many researchers are aiming to discover a methodology to help manage the symptoms associated with PCOS, especially in adolescents. This review will investigate management methods possible for adolescents with PCOS. Although the most preferred way to help reduce symptoms is through lifestyle modifications such as vigorous exercise and dietary regimens low in carbohydrates, pharmaceuticals are also offering promising results to adolescents with PCOS. Metformin, oral contraceptives, gonadotropin-releasing hormone (GnRH) antagonists, and other alternatives, including finasteride, eflornithine, fibroblast growth factors (FGFs), and vitamin D, are all shown to help improve insulin sensitivity and regulate menstrual cycles and reduce hirsutism. Epilatory and surgical measurements are also available; however, they are reserved for when all other methods fail and once adulthood or an appropriate age is reached. Although there are many pharmaceuticals available, it is necessary to evaluate each adolescent with PCOS uniquely and prescribe the appropriate pharmacotherapy regarding their symptoms.

Abstract
Polycystic ovary syndrome (PCOS) is one of the most common disorders among women in modern societies. A variety of factors can contribute to the development of PCOS. These women often exhibit high insulin resistance (IR), hyperandrogenism, irregular periods, and infertility. Dysbiosis of the gut microbiota (GMB) in women with PCOS has attracted the attention of many researchers. Porphyromonas spp., B. coprophilus, and F. prausnitzii are found in higher numbers in the gut of women with PCOS. Short-chain fatty acids (SCFAs), produced by the intestinal microbiota through fermentation, play an essential role in regulating metabolic activities and are helpful in reducing insulin resistance and improving PCOS symptoms. According to studies, the bacteria producing SCFAs in the gut of these women are less abundant than in healthy women. The effectiveness of using probiotic supplements has been proven to improve the condition of women with PCOS. Daily consumption of probiotics improves dysbiosis of the intestinal microbiome and increases the production of SCFAs.

Abstract
BACKGROUND Vitamin D (Vit D) deficiency has been linked to symptoms of polycystic ovary syndrome (PCOS), yet little is known about Vit D supplementation as a treatment for sexual dysfunction (SDy) in women with PCOS. AIM To explore the implications of serum total 25-hydroxyvitamin D (25[OH]D) and bioavailable 25[OH]D (bio-25[OH]D) status and replacement on women with PCOS and SDy. METHODS Reproductive-age women with PCOS who were not desiring fertility were eligible provided that they also had SDy, as assessed by the Female Sexual Function Index (FSFI), and were without severe depression, as evaluated by the Beck Depression Inventory II (BDI-II). Participants were given the recommended dietary allowance of Vit D (600 IU daily) plus hormonal contraception (HC; cyclic ethinyl estradiol/drospirenone) or no HC for 6 months. Comparisons between groups were analyzed by chi-square test and t-test, and Pearson's correlation coefficient analyzed correlations between FSFI with demographics, BDI-II, androgen levels, and total and bio-25[OH]D. OUTCOMES The outcomes included SDy (FSFI <26.55), total and serum bio-25[OH]D levels, and total and free testosterone. RESULTS A total of 42 women without severe depression completed the FSFI, with 28 (66.7%) having SDy. All FSFI domains, including arousal, lubrication, orgasm, and pain, were significantly lower as compared with women without SDy, with no associations with respect to demographics, total and free testosterone, or total and bio-25[OH]D. Vit D replacement was initiated with HC (n = 18) or no HC (n = 10), and for those completing the study, FSFI improved (score >26.55) in 61% (11/18) regardless of the treatment group. A time-treatment effect showed a significant change for the domain of orgasm, suggesting that HC had more of an impact than Vit D replacement. Improvement in sexual function as a dichotomous variable was not associated with age, body mass index, other demographics, total and free testosterone, total and bio-25[OH]D, or HC use. CLINICAL IMPLICATIONS Due to the prevalence of SDy in women with PCOS, efficacious treatment options are necessary. STRENGTHS AND LIMITATIONS This study is the first to analyze the effect of Vit D supplementation on SDy in women with PCOS. Limitations included the small number of participants who completed the study, thus limiting meaningful conclusions and generalizability. CONCLUSION Vit D status was not associated with SDy and BDI-II. While HC may have played a role, standard Vit D supplementation could not account for the noted improvement in FSFI in women with PCOS.

Abstract
Dysregulated Alzheimer's disease (AD)-associated protein expression is reported in polycystic ovary syndrome (PCOS), paralleling the expression reported in type 2 diabetes (T2D). We hypothesized, however, that these proteins would not differ between women with non-obese and non-insulin resistant PCOS compared to matched control subjects. We measured plasma amyloid-related proteins levels (Amyloid-precursor protein (APP), alpha-synuclein (SNCA), amyloid P-component (APCS), Pappalysin (PAPPA), Microtubule-associated protein tau (MAPT), apolipoprotein E (apoE), apoE2, apoE3, apoE4, Serum amyloid A (SAA), Noggin (NOG) and apoA1) in weight and aged-matched non-obese PCOS (n = 24) and control (n = 24) women. Dementia-related proteins fibronectin (FN), FN1.3, FN1.4, Von Willebrand factor (VWF) and extracellular matrix protein 1 (ECM1) were also measured. Protein levels were determined by Slow Off-rate Modified Aptamer (SOMA)-scan plasma protein measurement. Only APCS differed between groups, being elevated in non-obese PCOS women (p = 0.03) relative to the non-obese control women. This differed markedly from the elevated APP, APCS, ApoE, FN, FN1.3, FN1.4 and VWF reported in obese women with PCOS. Non-obese, non-insulin resistant PCOS subjects have a lower AD-associated protein pattern risk profile versus obese insulin resistant PCOS women, and are not dissimilar to non-obese controls, indicating that lifestyle management to maintain optimal body weight could be beneficial to reduce the long-term AD-risk in women with PCOS.

Abstract
This study was conducted in two groups of girls with PCOS (polycystic ovary syndrome) categorized as slim (group N) and overweight-to-obese (group Ov/Ob). The study's primary outcome was to assess the impact of a 12-week anti-inflammatory diet (AIDiet) intervention, without energy deficit, on daily diet quality improvement, evaluated according to the KIDMED index. The secondary outcome was improving inflammatory, redox, hormonal, and metabolic statuses. In the study, which was completed by 13 girls from the Ov/Ob group and 19 girls from the N group, a significant improvement in the mean KIDMED score was obtained. Moreover, the intervention significantly improves concentration of total antioxidant capacity (TAC), fasting insulin, and the homeostatic model assessment for insulin resistance (HOMA-IR) index, in the Ov/Ob group, while both groups experienced a reduction in the concentration of interleukin (IL)-1 and IL-6, tumour necrosis factor (TNF-α), and androstenedione. The AIDiet intervention effectively improved the quality of the subjects' diets, which was associated with the improvement of hormonal and immuno-metabolic markers. However, these changes in normal-weight patients were observed regardless of body weight reduction. ClinicalTrials.gov Identifier NCT04738409.

Metabolic health is characterized by optimal blood glucose, lipids, cholesterol, blood pressure, and adiposity. Alterations in these characteristics may lead to the development of type 2 diabetes mellitus or dyslipidemia. Recent evidence suggests that female reproductive characteristics may be overlooked as risk factors that contribute to later metabolic dysfunction. These reproductive traits include the age at menarche, menstrual irregularity, the development of polycystic ovary syndrome, gestational weight change, gestational dysglycemia and dyslipidemia, and the severity and timing of menopausal symptoms. These risk factors may themselves be markers of future dysfunction or may be explained by shared underlying etiologies that promote long-term disease development. Disentangling underlying relationships and identifying potentially modifiable characteristics have an important bearing on therapeutic lifestyle modifications that could ease long-term metabolic burden. Further research that better characterizes associations between reproductive characteristics and metabolic health, clarifies underlying etiologies, and identifies indicators for clinical application is warranted in the prevention and management of metabolic dysfunction.

Prevalence of Polycystic Ovarian Syndrome in Young and Adolescent Transmasculine Patients Presenting for Gender-Affirming Care. J Pediatr Adolesc Gynecol 2024; 37:51-55. [PMID: 37696388 DOI: 10.1016/j.jpag.2023.09.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 08/29/2023] [Accepted: 09/04/2023] [Indexed: 09/13/2023]
Abstract
STUDY OBJECTIVE To determine the incidence of polycystic ovarian syndrome (PCOS) and hyperandrogenism among adolescent transmasculine patients presenting to a tertiary care referral center for gender-affirming care METHODS: This was a retrospective study of adolescent transmasculine patients presenting to Cleveland Clinic for gender-affirming hormone therapy. The diagnostic criteria were adolescent-specific as defined by the international evidence-based guideline for PCOS management and included oligomenorrhea and/or anovulation with clinical and/or biochemical hyperandrogenism after exclusion of other androgen excess disorders. RESULTS The described transgender population had a prevalence of PCOS of 23.8%. The transmasculine patients who met the criteria for PCOS had both higher levels of androgens and higher body mass indexes when compared with the patients without PCOS. Additionally, the patients with PCOS had higher rates of dyslipidemia. CONCLUSION The prevalence of PCOS among transmasculine patients may be higher compared with the general population. Transmasculine patients with PCOS should be counseled regarding the long-term health implications associated with PCOS and screened appropriately to minimize risks.

The role of glycated hemoglobin in the diagnosis of prediabetes and diabetes mellitus in young women with polycystic ovary syndrome. Clin Endocrinol (Oxf) 2024; 100:124-131. [PMID: 37828797 DOI: 10.1111/cen.14982] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 08/19/2023] [Accepted: 10/01/2023] [Indexed: 10/14/2023]
Abstract
OBJECTIVE To compare glycated hemoglobin (HbA1c) and the oral glucose tolerance test (OGTT) for the diagnosis of prediabetes and diabetes in young women with polycystic ovary syndrome (PCOS). PATIENTS AND DESIGN This cross-sectional study included 154 women aged 20-40 years with a diagnosis of PCOS, who were screened for prediabetes and diabetes by the OGTT and HbA1c. Women with diabetes, hyperprolactinemia, thyroid or adrenal diseases, and anemia and users of hormonal contraception or corticosteroids were excluded. MEASUREMENTS Clinical, biochemical and ultrasound data were collected from the electronic medical records. The women were classified as having normal glucose metabolism, prediabetes, or diabetes based on the diagnostic tests. Sensitivity and specificity were calculated and the Kappa method was used to assess agreement between the two methods. RESULTS According to the OGTT and HbA1c values, 79.2% and 76% of the women were within the normal range, respectively, 16.8% and 19.5% had prediabetes, and 4% and 4.5% had diabetes (p > .05). The Kappa coefficient of 0.41 (95% confidence interval: 0.24-0.58) indicated medium agreement between methods. Considering the OGTT as the gold standard, the specificity of HbA1c was 89.5% and sensitivity was 85.7% in the diagnosis of prediabetes and 100% and 66.7%, respectively, in the diagnosis of diabetes. CONCLUSION The HbA1c, when compared to the OGTT, showed high sensitivity and specificity in the diagnosis of prediabetes in young women with PCOS.

Abstract
Food and nutrition-related factors, including foods and nutrients consumed, dietary patterns, use of dietary supplements, adiposity, and exposure to food-related environmental contaminants, have the potential to impact semen quality and male and female fertility; obstetric, fetal, and birth outcomes; and the health of future generations, but gaps in evidence remain. On 9 November 2022, Tufts University's Friedman School of Nutrition Science and Policy and the school's Food and Nutrition Innovation Institute hosted a 1-d meeting to explore the evidence and evidence gaps regarding the relationships between food, nutrition, and fertility. Topics addressed included male fertility, female fertility and gestation, and intergenerational effects. This meeting report summarizes the presentations and deliberations from the meeting. Regarding male fertility, a positive association exists with a healthy dietary pattern, with high-quality evidence for semen quality and lower quality evidence for clinical outcomes. Folic acid and zinc supplementation have been found to not impact male fertility. In females, body weight status and other nutrition-related factors are linked to nearly half of all ovulation disorders, a leading cause of female infertility. Females with obesity have worse fertility treatment, pregnancy-related, and birth outcomes. Environmental contaminants found in food, water, or its packaging, including lead, perfluorinated alkyl substances, phthalates, and phenols, adversely impact female reproductive outcomes. Epigenetic research has found that maternal and paternal dietary-related factors can impact outcomes for future generations. Priority evidence gaps identified by meeting participants relate to the effects of nutrition and dietary patterns on fertility, gaps in communication regarding fertility optimization through changes in nutritional and environmental exposures, and interventions impacting germ cell mechanisms through dietary effects. Participants developed research proposals to address the priority evidence gaps. The workshop findings serve as a foundation for future prioritization of scientific research to address evidence gaps related to food, nutrition, and fertility.

Abstract
Background Polycystic ovary syndrome (PCOS) is the most common metabolic-endocrine disorder impacting the health and quality of life of women over the lifespan. Evidence-based data on the scope of adverse health outcomes in those affected by PCOS is critical to improve healthcare and quality of life in this population. The aim of this study was to determine the prevalence of adverse health outcomes in those with PCOS compared to age-matched controls. Methods We conducted a retrospective observational case-control study in those diagnosed with PCOS and age-matched controls using the Alberta Health Services Health Analytics database and the International Classification of Diseases, for the period from 2002-2018 in Alberta, Canada. Results The cohort consisted of n = 16,531 exposed PCOS cases and n = 49,335 age-matched un-exposed controls. The prevalences of hypertension, renal disease, gastrointestinal disease, eating disorders, mental illness, depression-anxiety, rheumatoid arthritis, respiratory infections, and all malignancies were 20%-40% (P < 0.0001) higher in those with PCOS, compared to controls. The prevalence of obesity, dyslipidemia, nonalcoholic fatty liver disease, and type 2 diabetes was 2-3 fold higher in those with PCOS (P < 0.001). Cardiovascular, cerebrovascular, and peripheral vascular disease were 30%-50% higher, and they occurred 3-4 years earlier in those with PCOS (P < 0.0001); a 2-fold higher prevalence of dementia occurred in those with PCOS, compared to controls. Conclusion These findings provide evidence that PCOS is associated with a higher prevalence of morbidities over the lifespan, and the potential scope of the healthcare burden in women affected by PCOS.

Abstract
BACKGROUND Misdiagnosis is still an obstacle in the workup of polycystic ovary syndrome. We compared patients' characteristics among phenotypes of the syndrome and assessed the association of the characteristics with oligo-anovulation, hyperandrogenism, and polycystic ovary. METHODS In the infertility department of a teaching hospital, we performed a cross-sectional study. Based on the Rotterdam Criteria, we included 136 patients with polycystic ovary syndrome and 46 healthy controls. RESULTS The most common phenotype was A (N.=45;33%). Overall, A and C had larger Body Mass Index (P=0.019 and 0.030, respectively) and waist circumference (P=0.005 and 0.003) than control. Also, A and D had higher serum anti-mullerian hormone than control (both P<0.001) or phenotype C (P<0.001 and 0.01). Phenotypes A and C had higher insulin than control (both P=0.004). The highest level of estradiol was for control and the lowest for B. The lowest high-density lipoprotein was for C; and A to C phenotypes had higher triglyceride than control (P=0.002, <0.001, and 0.041). Larger body mass was associated with hyperandrogenism (adjusted Odds Ratio 95% CI=1.11 [1.01, 1.23], P=0.034); higher anti-mullerian hormone and high-density lipoprotein were related to oligo-anovulation (1.2 [1.07, 1.37], P=0.004; 1.1 [1.00, 1.13], P=0.041). Higher insulin and lower high-density lipoprotein were associated with polycystic ovary (1.11 [1.03, 1.21], P=0.013; 0.9 [0.82, 0.97], P=0.014). CONCLUSIONS There are potentials in Body Mass Index, waist circumference, serum anti-mullerian hormone, insulin, estradiol, high-density lipoprotein, and triglyceride concentration for differentiating the phenotypes of polycystic ovary syndrome and for more precise diagnosis of hyperandrogenism, oligo-anovulation, and polycystic ovary morphology.

Longitudinal analysis of external quality assessment of immunoassay-based steroid hormone measurement indicates potential for improvement in standardization. Front Mol Biosci 2024; 11:1345356. [PMID: 38357630 PMCID: PMC10865096 DOI: 10.3389/fmolb.2024.1345356] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 01/02/2024] [Indexed: 02/16/2024] Open
Abstract
As hormonal disorders are linked to several diseases, the accurate quantitation of steroid hormone levels in serum is crucial in order to provide patients with a reliable diagnosis. Mass spectrometry-based methods are regarded as having the highest level of specificity and sensitivity. However, immunoassays are more commonly used in routine diagnostics to measure steroid levels as they are more cost effective and straightforward to conduct. This study analyzes the external quality assessment results for the measurement of testosterone, progesterone and 17β-estradiol in serum using immunoassays between early 2020 and May 2022. As reference measurement procedures are available for the three steroid hormones, the manufacturer-specific biases were normalized to the reference measurement values. The manufacturer-specific coefficients of variation were predominantly inconspicuous, below 20% for the three hormones when outliers are disregarded, however there were large differences between the various manufacturer collectives. For some collectives, the median bias to the respective reference measurement value was repeatedly greater than ±35%, which is the acceptance limit defined by the German Medical Association. In the case of testosterone and progesterone determination, some collectives tended to consistently over- or underestimate analyte concentrations compared to the reference measurement value, however, for 17β-estradiol determination, both positive and negative biases were observed. This insufficient level of accuracy suggests that cross-reactivity continues to be a fundamental challenge when antibody detection is used to quantify steroids with a high structural similarity. Distinct improvements in standardization are required to provide accurate analysis and thus, reliable clinical interpretations. The increased accuracy of the AX immunoassay for testosterone measurement, as observed in the INSTAND EQAs between 2020 and 2022, could be the result of a recalibration of the assay and raises hope for further improvement of standardization of immunoassay-based steroid hormone analyses in the coming years.

Abstract
Polycystic ovary syndrome (PCOS) is a set of endocrine disorder syndrome characterized by ovulation disorder. Increased insulin resistance (IR) and compensatory hyperinsulinemia play a vital role in the pathogenesis of PCOS. Therefore, insulin sensitizing agents have been studied in the treatment of PCOS. Berberine (BBR) has been proved to alleviate IR in patients with PCOS, but the mechanism remained unclear. This study was aimed to verify the regulatory mechanism of BBR on PCOS-IR rats. Firstly, we established a female rat PCOS-IR model induced by dehydroepiandrosterone (DHEA) and found that estrus cycle was disrupted in the PCOS-IR group, serum fasting insulin (FINS) level and the homeostasis model assessment of insulin resistance (HOMA-IR) index were significantly higher than normal control group. BBR treatment could recover estrous cycle, reduce abnormal serum hormone levels like luteotropic hormone (LH) and testosterone (T). Most importantly, BBR could concentration-dependently reduce serum FINS level in PCOS-IR rat model. Meanwhile, BBR may improve the abnormal lipid metabolism levels in PCOS-IR group by decreasing low density lipoprotein (LDL), total cholesterol (TC) and triglyceride (TG). Histological results showed that BBR can also protect normal histological structures of ovaries in PCOS-IR rats. Our results indicated that BBR plays a protective role in PCOS-IR, increasing insulin sensitivity, improving hyperandrogens and recovering abnormal blood lipids. Therefore, Our research provides novel insights for therapeutic treatment of BBR in patients with glucolipid metabolic disturbances.

Abstract
We analyzed the medical condition of 360 women affected by lipedema of the lower limbs in stages 1, 2, and 3. The data were assessed for the whole population and compared between different clinical stages, distinguishing between obese and non-obese patients. The most frequent clinical signs were pain when pinching the skin, subcutaneous nodules, and patellar fat pads. The most frequently painful site of the lower limbs was the medial lower third of the thigh. The pain score obtained on lower limb points increased progressively with the clinical stage. In all points evaluated, the thickness of the subcutaneous tissue increased with the clinical stage. Analyzing the data on the lower medial third of the leg and considering only patients with type 3 lipedema, the difference between stages was statistically significant after correction for age and BMI. We found higher levels of C-reactive protein at more severe clinical stages, and the difference was significant after correction for age and BMI between the stages. Overall, the prevalence of alterations of glucose metabolism was 34%, with a progressive increase in prevalence with the clinical stage. The most frequent comorbidities were vitamin D insufficiency, chronic venous disease, allergies, dyslipidemia, headache, and depression of mood. Interestingly, in comparison with the general population, we found higher prevalence of chronic autoimmune thyroiditis and polycystic ovary syndrome. Finally, the clinical stage and the involvement of the upper limbs or obesity suggest a worse clinical, anthropometric, and endocrine-metabolic profile.

Abstract
Infertility is a condition defined by the failure to establish a clinical pregnancy after 12 months of regular, unprotected sexual intercourse or due to an impairment of a person's capacity to reproduce either as an individual or with their partner. The authors have set out to succinctly investigate, explore, and assess infertility treatments, harnessing the potential of stem cells to effectively and safely treat infertility; in addition, this paper will present the legal and regulatory complexities at the heart of stem cell research, with an overview of the legislative state of affairs in six major European countries. For couples who cannot benefit from assisted reproductive technologies (ART) to treat their infertility, stem-cells-based approaches have been shown to be a highly promising approach. Nonetheless, lingering ethical and immunological uncertainties require more conclusive findings and data before such treatment avenues can become mainstream and be applied on a large scale. The isolation of human embryonic stem cells (ESCs) is ethically controversial, since their collection involves the destruction of human embryonic tissue. Overall, stem cell research has resulted in important new breakthroughs in the treatment of infertility. The effort to untangle the complex web of ethical and legal issues associated with such therapeutic approaches will have to rely on evidence-based, broadly shared standards, guidelines, and best practices to make sure that the procreative rights of patients can be effectively reconciled with the core values at the heart of medical ethics.

Abstract
PURPOSE Polycystic ovarian syndrome (PCOS) is an endocrine-metabolic condition affecting 5-10% of reproductive-aged women and characterized by hyperandrogenism, insulin resistance (IR), and hyperinsulinemia. CFTR is known to be regulated by steroid hormones, and our previous study has demonstrated an essential role of CFTR in β-cell function. This study aims to investigate the contribution of androgen and CFTR to hypersecretion of insulin in PCOS and the underlying mechanism. METHODS We established a rat PCOS model by subcutaneously implanting silicon tubing containing Dihydrotestosterone (DHT). Glucose tolerance test with insulin levels was performed at 9 weeks after implantation. A rat β-cell line RINm5F, a mouse β-cell line β-TC-6, and mouse islets were treated with DHT, and with or without the androgen antagonist flutamide for CFTR and insulin secretion-related functional assays or mRNA/protein expression measurement. The effect of CFTR inhibitors on DHT-promoted membrane depolarization, glucose-stimulated intracellular Ca2+ oscillation and insulin secretion were examined by membrane potential imaging, calcium imaging and ELISA, respectively. RESULTS The DHT-induced PCOS model showed increased body weight, impaired glucose tolerance, and higher blood glucose and insulin levels after glucose stimulation. CFTR was upregulated in islets of PCOS model and DHT-treated cells, which was reversed by flutamide. The androgen receptor (AR) could bind to the CFTR promoter region, which was enhanced by DHT. Furthermore, DHT-induced membrane depolarization, enhanced glucose-stimulated Ca2+ oscillations and insulin secretion, which could be abolished by CFTR inhibitors. CONCLUSIONS Excessive androgen enhances glucose-stimulating insulin secretion through upregulation of CFTR, which may contribute to hyperinsulinemia in PCOS.

Abstract
STUDY OBJECTIVES Polycystic ovary syndrome (PCOS) confers a high risk of obstructive sleep apnea (OSA). Here we investigated the effect of OSA on first in vitro fertilization (IVF) cycle metrics and outcomes in patients with PCOS. METHODS This was a prospective cohort study of patients with PCOS undergoing their first IVF at a single tertiary center between October 1, 2021, and September 30, 2022. Patients were screened for OSA before IVF and grouped accordingly. Clinical and IVF cycle data were compared between groups. RESULTS OSA was found in 37.2% of 156 patients with PCOS, with longer infertility duration (4.3 ± 2.5 vs. 3.4 ± 2.0 years) and lower levels of anti-Müllerian and luteinizing hormones than patients without OSA (6.44 ± 2.96 vs 8.69 ± 4.03 µg/L and 6.30 ± 5.02 vs 8.46 ± 6.09 U/L). Antral follicle count was lower in patients with OSA (28.9 ± 12.4 vs 33.2 ± 12.9). During ovarian stimulation, patients with OSA required significantly higher doses of gonadotropin (2080.8 ± 1008.7 vs 1682.8 ± 619.9 U) and had lower peak estradiol level (4473.5 ± 2693.0 vs 5455.7 ± 2955.1 pmol/L) and fewer retrieved oocytes, high-quality, and available embryos (17.8 ± 7.2 vs 21.9 ± 10.5, 4.5 ± 4.4 vs 6.2 ± 4.6, 5.2 ± 4.3 vs 7.4 ± 5.0). Eleven patients were excluded for having no embryos or missing transfer. Therefore, we analyzed the outcome of the first embryo transfer in 145 patients. The biochemical and clinical pregnancy rates were lower in patients with OSA than patients without OSA (51.9% vs 66.7% and 42.3% vs 60.2%). OSA was independently associated with clinical pregnancy rate after controlling for several confounders (P = .043). CONCLUSIONS OSA impairs female fertility in patients with polycystic ovary syndrome, suggesting an adverse effect on in vitro fertilization cycle stimulation characteristics and clinical outcomes.

Abstract
Polycystic ovary syndrome (PCOS) is a major reproductive endocrine disorder affecting different facets of a woman's life, comprising reproduction, metabolism, and mental health. Recently, several research groups have brought attention to the therapeutic capacity of mesenchymal stem cells (MSCs) for the treatment of female reproductive disorders. It is highlighted that the treatment with bone marrow mesenchymal stem cells (BMMSCs) considerably diminishes the levels of some inflammatory markers as well as essential genes for ovarian production of androgens, which are considerably higher in theca cells of PCOS women than in those of healthy cases. In addition, studies show that BMMSCs improve in vitro maturation (IVM) of germinal vesicles (GVs) and the number of antral follicles while lessening the number of primary and preantral follicles in mice with PCOS compared to healthy controls. Regarding adipose- derived mesenchymal stem cells (AdMSCs), these cells restore the ovarian structure, enhance the number of oocytes and corpora luteum, and diminish the number of aberrant cystic follicles in PCOS rats. Some research also indicates that umbilical cord mesenchymal stem cells (UC-MSCs) alleviate the inflammation of granulosa cells in women with PCOS. Therefore, due to the limited research on MSC therapy in PCOS, in this review, we summarize the current knowledge on the therapeutic potential of three types of MSCs: BMMSCs, AdMSCs, UC-MSCs and their secretome in the treatment of PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is a highly prevalent endocrine disorder characterized by multifactorial and intricate pathogenesis. The discovery of novel markers has been a significant step toward understanding the mechanisms of PCOS. Galectin-3 has emerged as a novel factor in metabolic disorders. This meta-analysis examines the association between circulating Galectin-3 and PCOS. A systematic review and meta-analysis were performed to identify relevant articles in the electronic databases PubMed, Web of Science, Scopus, Cochrane, EMBASE, and Google Scholar. The search covered the period from January 2000 to March 2023 and followed a predefined search strategy. Eight articles were included in the analysis with a total of 594 participants (322 patients with PCOS and 272 controls). Pooled standardized mean difference (SMD) and 95 % confidence interval [CI] were used to evaluate the association between Galectin-3 levels and PCOS. The results indicated a significant association between PCOS and galectin-3 levels (SMD = 0.58; 95 % CI: 0.15-1.01; p = 0.007). In addition, subgroup analysis showed a significant difference in serum Galectin-3 levels in women with PCOS and a higher homeostatic model assessment for insulin resistance ratio (SMD = 0.89; 95 % CI: 0.45-1.33; p < 0.001). The researchers also performed meta-regression and subgroup analyses to specify sources of heterogeneity. The results of our meta-analysis suggest an association between increased levels of galectin-3 and PCOS. Galectin-3 plays a significant role in the progression of PCOS and could be used as a novel diagnostic biomarker. Nevertheless, it is essential to perform further studies to confirm and support our conclusions.

PCOS health-related quality-of-life and depressive symptoms across the lifespan: Comparative study. J Women Aging 2024; 36:45-60. [PMID: 37405955 DOI: 10.1080/08952841.2023.2230112] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 05/30/2023] [Accepted: 06/17/2023] [Indexed: 07/07/2023]
Abstract
The purpose of this cross-sectional study was to compare health-related quality of life (HRQoL) and depressive symptoms among peri-postmenopausal women with polycystic ovary syndrome (PCOS) aged ≥43 years relative to premenopausal women with PCOS aged 18-42 years. An online survey link comprising questionnaires about demographics, HRQoL, and depressive symptoms was posted onto two PCOS-specific Facebook groups. Respondents (n = 1,042) were separated into two age cohorts: women with PCOS aged 18-42 years (n = 935) and women with PCOS aged ≥43 years (n = 107). Data from the online survey were analyzed using descriptive statistics, Pearson correlations, and multiple regression via SAS. Results were interpreted through the lens of life course theory. All demographic variables, except for the number of comorbidities, significantly differed between groups. HRQoL among older women with PCOS was significantly better as compared to those aged 18-42 years. Results indicated significant positive linear associations between the HRQoL psychosocial/emotional subscale and other HRQoL subscales and a significant negative association with age. The fertility and sexual function HRQoL subscales were not significantly associated with the psychosocial/emotional subscale among women aged ≥43 years. Women in both groups had moderate depressive symptoms. Study findings demonstrate the need to tailor PCOS management to women's life stage. This knowledge can inform future research about peri-postmenopausal women with PCOS and age-appropriate and patient-centered healthcare, including requisite clinical screenings (e.g., depressive symptoms) and lifestyle counseling across the lifespan.

Polycystic ovary syndrome and its management: In view of oxidative stress. Biomol Concepts 2024; 15:bmc-2022-0038. [PMID: 38242137 DOI: 10.1515/bmc-2022-0038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Accepted: 12/11/2023] [Indexed: 01/21/2024] Open
Abstract
In the past two decades, oxidative stress (OS) has drawn a lot of interest due to the revelation that individuals with many persistent disorders including diabetes, polycystic ovarian syndrome (PCOS), cardiovascular, and other disorders often have aberrant oxidation statuses. OS has a close interplay with PCOS features such as insulin resistance, hyperandrogenism, and chronic inflammation; there is a belief that OS might contribute to the development of PCOS. PCOS is currently recognized as not only one of the most prevalent endocrine disorders but also a significant contributor to female infertility, affecting a considerable proportion of women globally. Therefore, the understanding of the relationship between OS and PCOS is crucial to the development of therapeutic and preventive strategies for PCOS. Moreover, the mechanistic study of intracellular reactive oxygen species/ reactive nitrogen species formation and its possible interaction with women's reproductive health is required, which includes complex enzymatic and non-enzymatic antioxidant systems. Apart from that, our current review includes possible regulation of the pathogenesis of OS. A change in lifestyle, including physical activity, various supplements that boost antioxidant levels, particularly vitamins, and the usage of medicinal herbs, is thought to be the best way to combat this occurrence of OS and improve the pathophysiologic conditions associated with PCOS.

Abstract
All girls presenting with virilization (which signifies severe hyperandrogenism) warrant thorough investigation. Ovarian hyperthecosis (OHT) is a rare cause of virilization in premenopausal women. Here, we report the case of a previously healthy 12-year-old Chinese girl with signs of virilization at puberty. Her serum total testosterone was elevated at 5.1 nmol/L (146.97 ng/dL) (normal: <1.4 nmol/L, <40.35 ng/dL). Workup for Cushing syndrome, sex development disorders, congenital adrenal hyperplasia, and adrenal and ovarian androgen-secreting tumors was unrevealing. Ovarian and adrenal venous sampling demonstrated ovarian hyperandrogenism without lateralization. Ovarian biopsy revealed nests of theca cells in the stroma of the right ovary, substantiating the diagnosis of OHT. A single dose of a GnRH analog resulted in the complete suppression of serum testosterone, supporting the diagnosis of OHT. Medical treatment with hormonal replacement therapy normalized serum testosterone levels. Our case report illustrates the diagnostic approach to virilization among girls at puberty and the diagnosis of OHT as the underlying pathology.

Integrated bioinformatics and network pharmacology to explore the therapeutic target and molecular mechanisms of Bailing capsule on polycystic ovary syndrome. BMC Complement Med Ther 2023; 23:458. [PMID: 38102584 PMCID: PMC10722827 DOI: 10.1186/s12906-023-04280-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 11/28/2023] [Indexed: 12/17/2023] Open
Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a complex endocrine and metabolic disorder that is common in women of reproductive age. The clinical features of PCOS include hyperandrogenemia and polycystic ovarian changes. Bailing capsule (BL), a proprietary Chinese medicine that contains fermented Cordyceps sinensis powder, has been applied to treat PCOS. However, the specific active ingredients of BL and its mechanisms of action are yet to be elucidated. METHODS Initially, the effectiveness of BL on PCOS model mice was evaluated. Subsequently, the active ingredients of BL were searched in the TCMSP and TCM Systems Pharmacology databases, and their targets were predicted using Swiss Target Prediction and SEA databases. Furthermore, the GEO gene database was used to screen for differentially expressed genes (DEGs) related to PCOS. Data from Gene Card, OMIM, DDT, and Drugbank databases were then combined to establish a PCOS disease gene library. Cross targets were imported into the STRING database to construct a protein-protein interaction network. In addition, GO and KEGG pathway enrichment analyses were performed using Metascape and DAVID databases and visualized using Cytoscape software and R 4.2.3. The core targets were docked with SYBYL-X software, and their expressions in PCOS mice were further verified using qPCR. RESULTS The core active ingredients of BL were identified to be linoleyl acetate, cholesteryl palmitate, arachidonic acid, among others. Microarray data sets from four groups containing disease and normal samples were obtained from the GEO database. A total of 491 DEGs and 106 drug-disease cross genes were selected. Estrous cycle and ovarian lesions were found to be improved in PCOS model mice following BL treatment. While the levels of testosterone, progesterone, and prolactin decreased, that of estradiol increased. qPCR findings indicated that the expressions of JAK2, PPARG, PI3K, and AKT1 were upregulated, whereas those of ESR1 and IRS1 were downregulated in PCOS model mice. After the administration of BL, the expressions of associated genes were regulated. This study demonstrated that BL exerted anti-PCOS effects via PIK3CA, ESR1, AKT, PPARG, and IRS1 targets affecting PI3K-Akt signaling pathways. DISCUSSION This research clarified the multicomponent, multitarget, and multichannel action of BL and provided a theoretical reference for further investigations on its pharmacological basis and molecular mechanisms against PCOS.

Influence of Phenotypes on the Metabolic Syndrome of Women with Polycystic Ovary Syndrome over a Six-Year Follow-Up in Brazil. Biomedicines 2023; 11:3262. [PMID: 38137483 PMCID: PMC10741024 DOI: 10.3390/biomedicines11123262] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 11/24/2023] [Accepted: 12/04/2023] [Indexed: 12/24/2023] Open
Abstract
BACKGROUND We followed polycystic ovary syndrome (PCOS) women with metabolic syndrome (MS) over a six-year treatment period and evaluated the influence of PCOS phenotypes on MS and on the risk for type 2 diabetes mellitus (T2DM). METHODS This was an observational study of 457 PCOS women, whose demographic, clinical, hormonal, and metabolic data underwent analysis. The PCOS women were divided into four groups per NIH recommendations. RESULTS After a follow-up of a mean of six years (1-20 years), 310 patients were selected to assess the development of T2DM and MS. The clinical and biochemical parameters, along with the Rotterdam phenotypes, were evaluated. Data were analyzed using Student's t- and the Pearson chi-square tests for data variation and group proportions, respectively. Additionally, multivariate analysis was applied to evaluate the effect of PCOS phenotypes on the risk for MS and T2DM. Patients of the four PCOS phenotypes did not differ in age, body mass index, total testosterone, insulin resistance, and dyslipidemia, but phenotype A patients showed the highest risk for T2DM. A decrease in androgen levels was not followed by an improved metabolic profile; instead, there was a significant increase in the number of T2DM cases. CONCLUSION Phenotype A women are at the highest risk for type 2 diabetes mellitus.

Beyond the Metabolic Syndrome: Non-Obvious Complications of Obesity in Children. CHILDREN (BASEL, SWITZERLAND) 2023; 10:1905. [PMID: 38136107 PMCID: PMC10742254 DOI: 10.3390/children10121905] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Revised: 11/24/2023] [Accepted: 12/06/2023] [Indexed: 12/24/2023]
Abstract
Obesity is currently one of the most significant public health challenges worldwide due to the continuous increase in obesity rates among children, especially younger children. Complications related to obesity, including serious ones, are increasingly being diagnosed in younger children. A search was performed from January 2023 to September 2023 using the PubMed, Cochrane Library, Science Direct, MEDLINE, and EBSCO databases. The focus was on English-language meta-analyses, systematic reviews, randomized clinical trials, and observational studies worldwide. Four main topics were defined as follows: disorders of glucose metabolism; liver disease associated with childhood obesity; the relationship between respiratory disorders and obesity in children; and the effects of obesity on the hypothalamic-pituitary-gonadal axis and puberty. Understanding potential complications and their underlying mechanisms can expedite the diagnostic process and enhance the effectiveness of treatment. We aspire that this study will bring insight into the often-overlooked complications associated with obesity.

Pharmacological investigation of vitamin E with combined oral contraceptives on INHBA gene against PCOS that intricate through melatonin PKC pathway. Syst Biol Reprod Med 2023; 69:450-464. [PMID: 37962399 DOI: 10.1080/19396368.2023.2276082] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Accepted: 10/22/2023] [Indexed: 11/15/2023]
Abstract
The most prevalent endocrine and metabolic condition in women of reproductive age are polycystic ovary syndrome (PCOS) with significant risk factors such as circadian rhythm and melatonin disruption. The aim of this study is to assess the effect of vitamin E in combination with a combined oral contraceptive (COC) on continuous light-induced PCOS using hormonal measures, oxidative stress (OS) indicators, and the inhibin beta-A (INHBA) gene, which targets the melatonin protein kinase C (PKC) pathway. An in silico technique anticipated INHBA's binding affinity for vitamin E and COC. For the in vivo investigation (IAEC/240/2021), female SD rats were divided into six groups and subjected to a 16-week induction period, followed by a 2-month test drug treatment with drospirenone (DRSP) as a standard. Serum testosterone, FSH, melatonin, and OS were calculated as hormonal markers. The expression of the INHBA gene was studied to see if it could be linked to the circadian rhythm and OS via the melatonin PKC pathway. According to the in silico study, vitamin E and DRSP had higher binding energy for the INHBA (-8.6 kcal/mol and -8.4 kcal/mol, respectively). When compared to the control group, in vivo results showed a substantial decrease in testosterone levels (p = .05), as well as changes in FSH (p = .78) and melatonin (p = .13). IHNBA gene expression has also dramatically increased, stimulating FSH production in the pituitary gland. Vitamin E and COC concomitantly are beneficial against PCOS because it modulates OS, which in turn influences circadian rhythm and the melatonin PKC pathway.

Abstract
Purpose of review a)The modifiable and non-modifiable determinants and the currently available methods of assessment of menstrual blood flow will be discussed, with the goal of helping healthcare providers, researchers, and those interested in public health. Recent findings b)Several factors can impact menstruation. The determinants include modifiable factors such as smoking, nutrition, exercise, stress, weight fluctuation, and benign gynecologic diseases, and non-modifiable factors such as age, race, and the individual's genes. The intertwined dynamic among these determinants needs more critical attention. Currently, the methods for the assessment of menstruation all have advantages and disadvantages, often with a tradeoff between practicality and accuracy. Summary c)Considered by many as the fifth vital, menstruation provides a window to an individual's general health. The discussion of its determinants and assessment can be more appropriate for individual contexts, especially from a public health perspective as it can improve the reproductive health of the population.

Progress of the application clinical prediction model in polycystic ovary syndrome. J Ovarian Res 2023; 16:230. [PMID: 38007488 PMCID: PMC10675861 DOI: 10.1186/s13048-023-01310-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Accepted: 11/05/2023] [Indexed: 11/27/2023] Open
Abstract
Clinical prediction models play an important role in the field of medicine. These can help predict the probability of an individual suffering from disease, complications, and treatment outcomes by applying specific methodologies. Polycystic ovary syndrome (PCOS) is a common disease with a high incidence rate, huge heterogeneity, short- and long-term complications, and complex treatments. In this systematic review study, we reviewed the progress of clinical prediction models in PCOS patients, including diagnosis and prediction models for PCOS complications and treatment outcomes. We aimed to provide ideas for medical researchers and clues for the management of PCOS. In the future, models with poor accuracy can be greatly improved by adding well-known parameters and validations, which will further expand our understanding of PCOS in terms of precision medicine. By developing a series of predictive models, we can make the definition of PCOS more accurate, which can improve the diagnosis of PCOS and reduce the likelihood of false positives and false negatives. It will also help discover complications earlier and treatment outcomes being known earlier, which can result in better outcomes for women with PCOS.
