Comparative efficacy of combined myo-inositol and D-chiro inositol versus metformin across PCOS Phenotypes: enhancing ovarian function, ovulation, and stress response in a prospective clinical trial.

This study aimed to evaluate the comparative efficacy of Myo-inositol (MI) and D-chiro-inositol (DCI) with metformin in enhancing ovarian function, promoting ovulation, and reducing perceived stress in patients with polycystic ovary syndrome (PCOS). Women with PCOS were identified using the Androgen Excess Society's criteria, and 60 participants were enrolled and divided equally into two groups. One group received a 40:1 ratio of MI plus DCI, while the other received metformin for a 12-week period. Endocrine and metabolic parameters, insulin-resistance, stress levels, and quality of life were assessed pre- and post-treatment. Both MI plus DCI and metformin significantly improved insulin sensitivity (HOMA-IR, p < 0.001), SHBG levels (p = 0.021), ovarian volume (p < 0.001), and menstrual regularity (p = 0.002), along with BMI, quality of life, and PSS scores (p < 0.001). Metformin showed slightly better outcomes in certain parameters, such as insulin sensitivity and endocrine markers, probably due to a higher representation of Phenotype A. In contrast, we hypothesize that MI plus DCI may be more effective for Phenotypes C and D. Our findings support both MI plus DCI and metformin as effective treatments for PCOS, with each treatment offering specific benefits. These results highlight the potential for a phenotype-specific tailored therapeutic approach to better manage the complex metabolic, endocrine, and stress-related challenges of PCOS.

Evaluation of Retinal Changes in Women with Different Phenotypes of Polycystic Ovary Syndrome.

Background: The aim of our study was to evaluate the retinal nerve fiber layer (RNFL) and macular and choroidal thicknesses in women with different phenotypes of polycystic ovary syndrome (PCOS), and compare these measurements with those of healthy women of reproductive age. Materials and Methods: This prospective case-control study included 120 eyes of 120 women with PCOS, with each of the four distinct phenotypes comprising 30 eyes of 30 women. Additionally, 30 eyes from 30 healthy women were included in the control group. All participants underwent comprehensive ophthalmologic examinations, and RNFL thickness, macular thickness (MT), and choroidal thickness (CT) in each eye were measured via spectral-domain optical coherence tomography. The body mass index (BMI) of the patients was recorded and compared with the retinal changes. Results: The average mean and nasal segments of the RNFL were significantly greater in the PCOS group than in the healthy control group (p < 0.001). There was a statistically significant difference in foveal retinal thickness between the groups (p < 0.001). Our study revealed significant choroidal tissue thickening subfoveally and at locations 500 μm temporal, 500 μm nasal, 1500 μm nasal, and 1500 μm temporal to the fovea in all phenotypes of the PCOS group (p < 0.001). Additionally, there was a positive correlation between BMI and all CT changes. Conclusions: Our findings indicate that the retinal layers and choroid are affected by all phenotypes of PCOS, one of the most common reproductive abnormalities, albeit to varying degrees. Furthermore, these changes were found to be correlated with BMI.

Comparing the Effect of Heat Therapy and Mitochondrial-Targeted Antioxidants in Polycystic Ovarian Syndrome Phenotype Induced by Junk Food Consumption.

Polycystic ovarian syndrome (PCOS) is a complex endocrine-metabolic disorder, and multiple factors contribute to its pathophysiology. The current study assessed a PCOS-like animal model induced by consuming a high-fat sugar (HFHS) diet and compared the treatment outcome of mitochondrial-targeted antioxidants versus heat therapy. Sixty rats were divided into the following study groups: three control groups (negative and positive for the treatments used), HFHS, hot tub therapy (HTT) treatment, and MitoQ10 treatment (500 µmol/L MitoQ10 in clean drinking water daily, from week fourteen till week twenty-two of the study). At week fourteen, PCOS was confirmed by vaginal smear examination; measurements of blood testosterone (T), anti-Mullerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), glucose, and insulin; and determination of the homeostatic model assessment of IR (HOMA-IR). At week 22, blood samples were collected for measurement of the serum LH, FSH, AMH, T, insulin, glucose, lipid profile, kisspeptin, ADAM metallopeptidase with thrombospondin type 1 motif 19 (ADAMTS19), S100 calcium-binding protein B (S100B), fibulin 1 (FBLN1), immunoglobulin free light chains (FLCs), kappa and lambda. Ovaries were examined for morphological changes; for the levels of glutathione (GSH), catalase, SOD, malondialdehyde (MDA), and nitric oxide (NO); and the expression of FK506 binding protein 52 (FKBP52) and the androgen receptor (AR). The consumption of HFHS diet-induced PCOS-like features, which have been ameliorated by both HTT and mitoQ10 as potential therapies, with MitoQ10 showing a superior effect over HTT.

The Influence of Study Quality, age, and Geographic Factors on Pcos Prevalence - A Systematic Review and Meta-Analysis.

Polycystic ovary syndrome (PCOS) is a highly prevalent disorder with substantial burden, yet global epidemiological data remains limited. To estimate the PCOS prevalence globally. We systematically searched PubMed and Embase for PCOS studies in unselected populations through February 2024. Our study included 88 studies (n=561,287 women) from 7,144 records. The highest PCOS prevalence was identified by Rotterdam criteria, followed by Androgen Excess and PCOS Society (AE-PCOS), and National Institutes of Health (NIH). High-quality studies indicated prevalences of 10.89%, 10.61%, and 6.63% using Rotterdam, AE-PCOS, and NIH, respectively. Considering only high-quality studies, as assessed using a newly developed PCOS Epidemiology and Phenotype (PEP) tool, revealed no significant regional disparities using either NIH (ranging from 5.72% in Eastern Mediterranean Region [EMR] to 6.90% in Western Pacific Region [WPR]) or Rotterdam (ranging from 11.15% in South-East Asia to 9.12% in EMR). For AE-PCOS, sufficient data was available only for WPR region (6.9%). No studies were available in the African Region. A higher PCOS prevalence was observed in adults than adolescents using NIH (8.52% vs. 4.44%; p= 0.01), although the difference diminished when considering only high-quality studies (7.25% vs. 4.44%; p= 0.053). Limited data restricted age-group comparisons using Rotterdam and AE-PCOS. This systematic review and meta-analysis reveals a trend towards regional variations and age differences across diagnostic criteria. The study results suggest considering study quality using instruments tailored for epidemiological studies in PCOS, such as the PEP tool, when carrying out these types of meta-analyses.

Exploring CTRP6: a biomarker and therapeutic target in metabolic diseases.

The rising prevalence of metabolic diseases is a significant global health concern. Beyond lifestyle management, targeting key molecules involved in metabolic regulation is essential. C1q/TNF-related protein 6 (CTRP6) is notably associated with glucose and lipid metabolism, with numerous studies highlighting its regulatory functions in metabolic diseases. This review summarizes the current knowledge on CTRP6, focusing on its gene expression profiles, protein structure, gene regulation, and role in metabolic diseases. CTRP6 is widely expressed across various tissues and features four distinct domains, with the C1q domain predicted to bind to its receptor. Notably, serum levels of CTRP6 are significantly elevated in patients with obesity and type 2 diabetes. In these conditions, adipose tissue serves as a key source of CTRP6, and its involvement in adipose tissue expansion, inflammation, and nutrient sensing has been observed in several studies. CTRP6 is also implicated in type 1 diabetes, gestational diabetes mellitus, and diabetic complications, particularly diabetic nephropathy. Although some studies have suggested that CTRP6 has protective roles in atherosclerotic cell models, myocardial infarction rat models, and ischemia/reperfusion injury mouse models, methodological issues such as unreliable antibodies and unstrict controls make it difficult to draw accurate conclusions from these studies. Patients with polycystic ovary syndrome (PCOS) exhibit elevated serum levels of CTRP6, though its direct impact on PCOS phenotypes remains unclear. In conclusion, CTRP6 emerges as a promising therapeutic target for metabolic diseases. A deeper understanding of CTRP6 will empower the scientific community to develop effective interventions to address the increasing prevalence of these diseases.

A Ketogenic Diet Followed by Gradual Carbohydrate Reintroduction Restores Menstrual Cycles in Women with Polycystic Ovary Syndrome with Oligomenorrhea Independent of Body Weight Loss: Results from a Single-Center, One-Arm, Pilot Study.

Background/Objectives: Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of fertile age. Some studies suggest that a ketogenic diet (KD) may have a role in treating PCOS. We aimed to demonstrate the long-term effectiveness of a KD in PCOS. Methods: Eighteen patients with PCOS phenotype A were enrolled: 28% were of normal weight, 28% were overweight, and 44% had obesity. All participants followed a KD without meal replacements for 45 days. After this period, patients underwent gradual carbohydrate reintroduction over 45 days, and thereafter healthy eating indications were given. Twelve patients completed the study. The patients were assessed at baseline and after 6 months. Anthropometric data, body composition, pelvic ultrasound, blood chemistry, hirsutism, and menstrual cycles frequency were recorded; Results: Besides improvement in anthropometric parameters, menstrual cycles (p 0.012), ovarian volume (p 0.029), FSH (p 0.05), LH (p 0.037), and progesterone (p 0.017) improved independently of weight or fat loss. However, testosterone and hirsutism improvements were influenced by weight and fat mass reduction. Conclusions: Our study showed that a KD followed by gradual carbohydrate reintroduction in PCOS has beneficial effects medium term, mostly independent of body weight loss, even in normal-weight women, suggesting that nutritional ketosis exerts beneficial effects per se.

Thyroid autoimmunity in different phenotypes of polycystic ovary syndrome: a single-center experience.

Polycystic ovary syndrome (PCOS) has been associated with Hashimoto's thyroiditis (HT) and 4 phenotypes have been described in this syndrome. The aim of this work was to investigate the frequency of anti-thyroid antibodies (TAb) and thyroid function in the 4 phenotypes of PCOS. This study included 448 patients with PCOS: 260 (58.0%) with phenotype A, 119 (26.6%) with phenotype B, 38 (8.5%) with phenotype C and 31 (6.9%) with phenotype D. TAb positivity was detected in 90/448 patients (20.1%) and was statistically significant higher (p = 0.03) in the grouped phenotypes A-B (83/379, 21.9%) than in phenotypes C-D (7/69, 10.1%). Positive anti-thyroglobulin antibodies (TgAb) were detected in 74/448 (16.5%) patients and positive anti-thyroperoxidase antibodies (TPOAb) in 66/448 (14.7%) patients. Both TgAb and TPOAb positivity was higher but not statistically significant in phenotype A-B than phenotype C-D. High titer TgAb (> 100UI/ml) frequency was significantly higher (p = 0.005) in grouped phenotypes A-B (39/379, 10.3%) than in phenotypes C-D (0/69, 0.0%), while no significant difference was observed for low titer TgAb (≤ 100UI/ml). According to a binary logistic regression analysis hypothyroidism was significantly associated with TAb positivity (OR 4.19; CI 2.25-7.79; p < 0.01) but not with PCOS phenotype. Androgen profile was not associated with TAb positivity. A higher frequency of positive TAb and of high titer TgAb and TPOAb have been detected in PCOS women with phenotypes A and B, probably in relation to the greater imbalances between estrogen and progesterone levels present in these phenotypes.

Integrated data driven analysis identifies potential candidate genes associated with PCOS

Polycystic ovary syndrome (PCOS) is one of the most common anovulatory disorder observed in women presenting with infertility. Several high and low throughput studies on PCOS have led to accumulation of vast amount of information on PCOS. Despite the availability of several resources which index the advances in PCOS, information on its etiology still remains inadequate. Analysis of the existing information using an integrated evidence based approach may aid identification of novel potential candidate genes with a role in PCOS pathophysiology. This work focuses on integrating existing information on PCOS from literature and gene expression studies and evaluating the application of gene prioritization and network analysis to predict missing novel candidates. Further, it assesses the utility of evidence-based scoring to rank genes for their association with PCOS. The results of this study led to identification of ~2000 plausible candidate genes associated with PCOS. Insilico validation of these identified candidates confirmed the role of 938 genes in PCOS. Further, experimental validation was carried out for four of the potential candidate genes, a high-scoring (PROS1), two mid-scoring (C1QA and KNG1), and a low-scoring gene (VTN) involved in the complement and coagulation pathway by comparing protein levels in follicular fluid in women with PCOS and healthy controls. While the expression of PROS1, C1QA, and KNG1 was found to be significantly downregulated in women with PCOS, the expression of VTN was found to be unchanged in PCOS. The findings of this study reiterate the utility of employing insilico approaches to identify and prioritize the most promising candidate genes in diseases with a complex pathophysiology like PCOS. Further, the study also helps in gaining clearer insights into the molecular mechanisms associated with the manifestation of the PCOS phenotype by contributing to the existing repertoire of genes associated with PCOS.

Investigating the self-healing potential of polycystic ovary syndrome in a mouse model: Implications for offspring health.

Polycystic ovarian syndrome (PCOS) is a prevalent metabolic endocrine disorder in reproductive-aged women. This study aims to investigate the self-healing ability of PCOS and its potential impact on offspring. Methods: Female C57 BL/6J mice aged 4-5 weeks were administered letrozole (1mg/kg/d) and a high-fat diet for 21 days to establish a PCOS model, and a control group was established. After modeling, the mice were divided into a PCOS model group and a self-healing group. After 14 days, the mice were mated, and the growth of their offspring was recorded. Subsequently, all mice were euthanized to collect serum, ovaries, and testes. The results showed that the self-healing group PCOS phenotype has shown improvement when compared to the model group. The findings from the offspring study indicate that all offspring in the model group died, while the self-healing group had offspring with a lower weight at 7 days and higher blood glucose levels. Additionally, the testicular morphology of male offspring in the self-healing group was poor. The conclusion drawn is that, after removing the pathogenic factors, the PCOS model group can self-heal. However, fertility remains impaired, which has an impact on their offspring.

LncRNA MEG3, GAS5, and HOTTIP Polymorphisms Association with Risk of Polycystic Ovary Syndrome: A Case-Control Study and Computational Analyses.

As a multifactorial and endocrine disease, polycystic ovary syndrome (PCOS) affects approximately 5-20% of women worldwide. Recently, long noncoding RNAs (lncRNAs) have emerged as potent predictors of a particular phenotype in PCOS. Our preliminary study examines the link between polymorphisms in lncRNAs MEG3, HOTTIP, and GAS5 and the risk of PCOS. The present study included 200 women with PCOS and 200 healthy women. The studied variations were genotyped by applying the PCR-RFLP and the tetra-ARMS-PCR reaction) techniques. The effect of variation in lncRNA on miRNA:lncRNA interactions, lncRNA-RNA interaction network, and the impact of the variations on the splicing site were predicted using different computational databases. The codominant heterozygous (TC vs. TT) model, the dominant (TC + CC vs. TT) model, the overdominant (TT + CC vs. TC) model, the C allele of rs2023843, and the C allele of rs55829688 had a protective role against PCOS. The A allele of rs4081134 and G allele of rs7158663 of the MEG3 conferred an increased risk of PCOS by 1.37 and 1.44 folds, respectively. The interaction analysis revealed that TC/GG/AA/TC and TC/GG/GA/TC strongly decreased the risk of PCOS by 94 and 92%, respectively. Interestingly, MEG3 and HOTTIP variants can create or disrupt binding sites for several splicing factors. In our population, MEG3 rs4081134 and rs7158663, GAS5 rs55829688, and HOTTIP rs2023843 polymorphisms were associated with PCOS risk. Replication studies on larger sample sizes must be conducted to confirm these findings and investigate other potential causative factors involved in the pathophysiology of PCOS.

Morphological and Redox/Glycative Alterations in the PCOS Oviducts: Modulating Effects of Carnitines in PCOS Mice.

Polycystic ovarian syndrome (PCOS) is a heterogeneous condition characterized by hyperandrogenism (HA), polycystic ovaries, and dysfunctional ovulation, and it is associated with metabolic problems such as insulin resistance (IR) and obesity. After having investigated the morphological and antioxidant/antiglycative alterations on mouse ovaries and uteri, we here focus on PCOS oviducts, a tract of the reproductive system essential for the nourishment and transport of gametes and embryos. The modulating effects of L-carnitine (LC) and acetyl-L-carnitine (ALC) were also assessed. CD1 mice were administered or not with dehydroepiandrosterone (DHEA, 6 mg/100 g body weight) for 20 days, alone or with 0.40 mg of L-carnitine (LC) and 0.20 mg of acetyl-L-carnitine (ALC). Oviducts were then subjected to histology and immunohistochemistry to evaluate their morphology and collagen deposition, and steroidogenesis. Oxidative, mitochondrial, and methylglyoxal (MG)-dependent damage was also investigated. Transmission electron microscopy was used to detect ultrastructural alterations. The PCOS oviducts were affected by hyperfibrosis, hyperplasia, hypertrophy, and altered steroidogenesis, with oxidative alterations associated with MethylGlyoxal-Advanced Glycation End product (MG-AGE) accumulation. A reduced ciliary coverage and numerous dilated intercellular spaces were found in the epithelium. LC-ALC administration mitigated PCOS oviductal alterations. These results provide evidence for the detrimental action of oxidative and glycative stress in PCOS oviducts, confirming a protective role of carnitines on the PCOS phenotype.

Improving the Dehydroepiandrosterone Induced PCOS Rat Model: Interplay of Age, High Fat Diet, and Treatment Regimen on Reproductive and Metabolic Phenotypes

Polycystic ovary syndrome (PCOS) is a ubiquitous reproductive condition with triggering hallmarks such as glucose intolerance, hyperandrogenism, and dyslipidemia. Despite the existence of various PCOS animal models, an ideal model which could encompass all PCOS-specific phenotype is of dire need. Dehydroepiandrosterone (DHEA) induced PCOS rats are frequently employed; though, determining the superior model among pubertal and prepubertal rats, incorporation of high fat diet (HFD), and their sustainability remains uncertain. This study aims to examine the age factor, impact of HFD, and DHEA regimen in model development. Prepubertal and pubertal Sprague–Dawley rats were subcutaneously injected with DHEA (6 mg/kg and 60 mg/kg/day, respectively) with and without HFD up to 21 days. Serum testosterone, glucose, lipid profile, ovary morphology, and estrous cycle were evaluated. Following 21 days of treatment with DHEA, pubertal PCOS rats exhibited better reproductive phenotype than prepubertal rats. However, there was no significant difference in the lipid profile. Accordingly, both the age-group rats were concomitantly treated with DHEA and HFD for additional 3 weeks on alternate day basis after model development. The persistence of reproductive and metabolic features on treatment withdrawal were also simultaneously investigated by alienating the rats into continuous and stop dosing groups. The DHEA + HFD and DHEA treated pubertal rats in continuous dosing group showed significant PCOS features (p < 0.05) compared to stop dosing, prepubertal, and control groups. To conclude, continual dosing with DHEA on alternate days for 3 weeks is necessary to sustain metabolic and reproductive phenotypes of PCOS.

Utilizing follicular fluid on endometrial stromal cells enhances decidualization by induced inflammation.

Polycystic ovary syndrome (PCOS) is a disease associated with inflammation and the follicular fluid of this patient contains proinflammatory cytokines. Abdominal obesity (AO) is also linked to increased levels of proinflammatory cytokines. This study investigated the induction of inflammation and decidualization of in vitro cultured endometrial stromal cells (ESCs) obtained from women with a normal uterus using the follicular fluid of PCOS and non-PCOS patients with or without abdominal obesity. Forty patients under 35 years old, referred to the Royan Institute, were divided into four groups: PCOS with AO, PCOS without AO, non-PCOS with AO, and non-PCOS without AO. Follicular fluid samples were added to the culture medium of ESCs for each group. The rate of decidualization was measured by examining decidual markers. The study also investigated morphological changes in uterine endometrial cells, cell migration rates, and gene expression across all groups. We found that the non-PCOS group without AO had the highest decidualization potential and the highest expression of decidualization markers (P ≤ 0.05). Groups with an inflammatory phenotype of PCOS or abdominal obesity showed the highest expression of decidual pathway markers. The expression levels of inflammatory and proliferative markers in the PCOS group with AO were significantly higher than in the other groups (P ≤ 0.05). The inflammatory profile present in the follicular fluid may trigger the decidualization process. Consequently, in the future, follicular fluid could be utilized as a natural supplement with human cells to promote decidualization and enhance endometrial receptivity in assisted reproductive technology.

Angiotensin-converting-enzyme gene insertion-deletion polymorphism and renin angiotensin aldosterone system activity in different phenotypes of polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a common condition. Its pathophysiology involves an interaction between genetic and environmental factors, resulting in different reproductive and metabolic subtypes. Genetic variation in the angiotensin converting enzyme (ACE) gene has been implicated in the pathophysiology of the syndrome. Our project aims to investigate the relationship between the ACE I/D (insertion/deletion) polymorphism and circulating levels of ACE activity, renin and aldosterone in PCOS. Patients and methodsPCOS and healthy donors were enrolled over 2 years. The Rotterdam criteria were used to segregate 4 phenotypes. Enrolled controls were matched to PCOS patients for body mass index. Clinical data were recorded and blood samples were taken for analysis of ACE I/D polymorphism and biochemical parameters. Hardy-Weinberg equilibrium evaluation, mean/median comparison and Spearman correlation were performed. ResultsA total of 102 women with PCOS and 107 controls were involved in the study. The most common polymorphism was ID, both in the control and PCOS groups. Renin levels in PCOS patients were positively correlated with luteinizing hormone (LH) and anti-mullerian hormone (AMH) in the ID genotype and with testosterone, free androgen index and insulin in the DD genotype. ConclusionThe ACE I/D variation may influence the pathophysiology of PCOS subtypes, together with an indirect relationship with renin. Our findings may provide valuable therapeutic insights into the management of PCOS, particularly regarding the potential need for ACE inhibitors or renin inhibitors tailored to ACE gene I/D genotypes or specific subtypes.

Rare variation in LMNA underlies polycystic ovary syndrome (PCOS) pathogenesis in two independent cohorts.

Polycystic ovary syndrome (PCOS) is a common, heritable endocrinopathy that is a common cause of anovulatory infertility in reproductive age women. Variants in LMNA cause partial lipodystrophy, a syndrome with overlapping features to PCOS. We tested the hypothesis that rare variation in LMNA contributes to PCOS pathogenesis and selects a lipodystrophy-like subtype of PCOS. We sequenced LMNA by targeted sequencing a discovery cohort of 811 PCOS patients and 164 healthy controls. We then analyzed LMNA from whole-exome sequencing (WES) of a replication cohort of 718 PCOS patients and 281 healthy controls. Variation in the LMNA gene, hormone and lipid profiles of participants. In the discovery cohort, we identified 8 missense variants in 15/811 cases, and 1 variant in 1/172 reproductively healthy controls. There is strong evidence for association between the variants and PCOS compared to gnomAD non-Finnish European population controls (χ2=17, p=3.7x10-5, OR=2.9). In the replication cohort, we identified 11 unique variants in 15/718 cases, and 1 variant in 281 reproductively healthy controls. Again, there is strong evidence for association with population controls (χ2=30.5, p=3.4x10-8, OR= 4.0). In both the discovery and replication cohorts, variants in LMNA identify women with PCOS with high triglycerides and extreme insulin resistance. Rare missense variation in LMNA is reproducibly associated with PCOS and identifies some individuals with lipodystrophy-like features. The overlap between this PCOS phenotype and genetic partial lipodystrophy syndromes warrants further investigation into additional lipodystrophy genes and their potential in PCOS etiology.

Prevalence, Phenotypes, and Comorbidities of Polycystic Ovary Syndrome Among Indian Women

The prevalence of polycystic ovary syndrome (PCOS) varies across the globe. Indian studies on PCOS are limited by poor design, small sizes, regional representations, and varying methods. To estimate the nationwide prevalence of PCOS in India, examine the phenotypic spectrum, and assess the magnitude of comorbidities associated with PCOS. This cross-sectional study recruited 9824 women aged 18 to 40 years from November 1, 2018, to July 31, 2022, across 5 zones of the country. A prevalidated questionnaire dichotomized women into screen-positive and screen-negative groups. Relevant clinical, hormonal, and sonographic assessments categorized women as either women with criteria-based PCOS (ie, National Institutes of Health [NIH] 1990 criteria, Rotterdam 2003 criteria, or Androgen Excess and Polycystic Ovary Syndrome Society [AE-PCOS] criteria), women with partial phenotypes (hyperandrogenism, oligomenorrhea, or polycystic morphology labeled as pre-PCOS), or healthy women, in addition to quantitating various comorbidities. The prevalence and phenotypes of PCOS among women of reproductive age and the burden of comorbidities associated with PCOS. A total of 8993 women (mean [SD] age, 29.5 [6.2] years) were enrolled in this study; 196 women were already diagnosed with PCOS, 2251 were categorized as screen positive, and 6546 were categorized as screen negative. The mean (SD) age of screen-positive women (28.1 [6.4] years) was lower than that of screen-negative women (29.7 [6.1] years) (P < .001), and the mean (SD) age at menarche was higher in the former group (13.2 [1.3] vs 13.1 [1.2] years; P < .001). The national prevalence of PCOS was 7.2% (95% CI, 4.8%-10.8%) by NIH 1990 criteria, 19.6% (95% CI, 12.7%-29.2%) by Rotterdam 2003 criteria, and 13.6% (95% CI, 8.4%-21.6%) by AE-PCOS criteria. Overall, PCOS phenotypes C (501 [40.8%]) and D (301 [24.6%]) were the most common, and 492 women (pre-PCOS subgroup) had oligomenorrhea (n = 75), hyperandrogenism (n = 257), or polycystic ovarian morphology (n = 160) only. Among women with PCOS (n = 1224), obesity was present in 529 (43.2%), dyslipidemia in 1126 (91.9%), nonalcoholic fatty liver disease in 403 (32.9%), metabolic syndrome in 305 (24.9%), impaired glucose tolerance in 111 (9.1%), diabetes in 41 (3.3%), and hypertension in 101 (8.3%). The pre-PCOS subgroup (n = 492) displayed similar metabolic aberrations (dyslipidemia: 390 [79.3%]; metabolic syndrome: 78 [15.9%]; nonalcoholic fatty liver disease: 163 [33.1%]; impaired glucose tolerance: 62 [12.6%]; diabetes: 7 [1.4%]; and hypertension: 26 [5.3%]). In this cross-sectional study of reproductive-age women recruited across India, the prevalence of PCOS was high, with phenotype C being predominant. Most of these women had metabolic abnormalities. These findings are crucial for developing preventive and therapeutic strategies, potentially integrating PCOS management into national health programs.

Non-pharmacological interventions of traditional Chinese medicine in treating polycystic ovary syndrome: a group consensus

BackgroundTo make a group consensus about non-pharmacological interventions of traditional Chinese medicine in treating polycystic ovary syndrome based on the previous guidelines, literature, and expert viewpoints. MethodsOrganized by Chinese Integrative Medicine & Traditional Chinese Medicine Academy, Chinese Maternal and Child Health Association, China, 29 experts from 18 Chinese provinces and 2 international experts, who specialize in gynecology, obstetrics, pediatrics, endocrinology, cardiovascular, psychology, reproductive genetics, nursing, acupuncture and tuina, traditional Chinese medicine, integrative medicine, and other disciplines, discussed and revised the recommendations one by one through in-person or online communication. Each recommendation was approved by ≥90% of the experts before it could be established. The main outcome measure is an optimal clinical regimen for addressing the requirements of women with PCOS and improving their quality of life. Result(s)The writing panel drafted the initial report, following a consensus process via adequate communication, which was then reviewed and revised by the consensus panel. This consensus provides 12 non-pharmacological interventions (including acupuncture, thumbtack needle, thread-embedding therapy, TEAS, AA, acupoint hot compress, cupping, acupressure, moxibustion, five elements music, aromatherapy, traditional Chinese exercises) for 8 phenotypes of PCOS, resulting in 34 items of clinical practice recommendations. Conclusion(s)The consensus provides 12 non-pharmacological interventions of traditional Chinese medicine for 8 phenotypes of PCOS, resulting in 34 items of clinical practice recommendations, which may be improved by more high-quality multicenter clinical trials.

Serum pentraxin-3 expression varies according to polycystic ovary syndrome phenotypes.

Pentraxin-3 (PTX-3) is a multibiological protein involved in cumulus cell expansion, fertilization, and implantation. This study was designed to analyze how circulating PTX-3 levels change in women with polycystic ovary syndrome (PCOS). A total of 50 Turkish participants, 35 of whom had PCOS and 15 of whom were fertile, were included in the study. Patients in the PCOS group were divided into 4 different phenotypes according to the NIH criteria (phenotypes A-D). The number of patients in phenotype A was the highest 13 (37.1%). In the calculations made without phenotyping, the serum ptx3 levels of the PCOS group were found to be significantly lower compared to the fertile control group (3.32 ± 0.73 ng/mL vs 4.97 ± 1.29 ng/mL; P < .001). The ptx3 value of phenotypes A and B was significantly lower than phenotype D (P = .008 and P = .009, respectively). When the phenotypes were compared with the fertile control group, the PTX-3 levels of phenotypes A and B were significantly lower than the fertile group. Although the ptx3 levels of phenotypes C and D were lower than the fertile group, the difference did not reach statistical significance. This is the first study to investigate serum ptx3 levels by phenotype in PCOS. While serum PTX-3 levels decreased in phenotypes A and B, ptx3 levels in phenotypes C and D were similar in fertile patients.
