Overweight and obese but not normal weight women with PCOS are at increased risk of Type 2 diabetes mellitus-a prospective, population-based cohort study

Metformin and Combined Oral Contraceptive Pills in the Management of Polycystic Ovary Syndrome: A Systematic Review and Meta-analysis

CONTEXT

Polycystic ovary syndrome (PCOS) affects more than 1 in 10 women.

OBJECTIVE

As part of the 2023 International PCOS Guidelines update, comparisons between combined oral contraceptive pills (COCP), metformin, and combination treatment were evaluated.

DATA SOURCES

Ovid Medline, Embase, PsycINFO, All EBM, and CINAHL were searched.

STUDY SELECTION

Women with PCOS included in randomized controlled trials (RCTs).

DATA EXTRACTION

We calculated mean differences and 95% CIs regarding anthropometrics, metabolic, and hyperandrogenic outcomes. Meta-analyses and quality assessment using GRADE were performed.

DATA SYNTHESIS

The search identified 1660 publications; 36 RCTs were included. For hirsutism, no differences were seen when comparing metformin vs COCP, nor when comparing COCP vs combination treatment with metformin and COCP. Metformin was inferior on free androgen index (FAI) (7.08; 95% CI 4.81, 9.36), sex hormone binding globulin (SHBG) (-118.61 nmol/L; 95% CI -174.46, -62.75) and testosterone (0.48 nmol/L; 95% CI 0.32, 0.64) compared with COCP. COCP was inferior for FAI (0.58; 95% CI 0.36, 0.80) and SHBG (-16.61 nmol/L; 95% CI -28.51, -4.71) compared with combination treatment, whereas testosterone did not differ. Metformin lowered insulin (-27.12 pmol/L; 95% CI -40.65, -13.59) and triglycerides (-0.15 mmol/L; 95% CI -0.29, -0.01) compared with COCP. COCP was inferior for insulin (17.03 pmol/L; 95% CI 7.79, 26.26) and insulin resistance (0.44; 95% CI 0.17, 0.70) compared with combination treatment.

CONCLUSIONS

The choice of metformin or COCP treatment should be based on symptoms, noting some biochemical benefits from combination treatment targeting both major endocrine disturbances seen in PCOS (hyperinsulinemia and hyperandrogenism).

International evidence-based guideline on assessment and management of PCOS-A Nordic perspective

Polycystic ovary syndrome (PCOS) affects about 12% of women of reproductive age. In 2018, the first evidence-based guideline on assessment and management of PCOS was published, and an updated extended guideline was released in August 2023. These guidelines followed best practice and are endorsed by 39 organizations worldwide, making them the most robust source of evidence to guide clinical practice. In the 2023 guideline, diagnostic criteria have been further refined as polycystic ovary morphology can now be assessed with gynecological ultrasound or elevated anti-Müllerian hormone levels. A healthy lifestyle should be at the focus of care for all women with PCOS; however, with no specific diet or physical exercise recommended. The latest evidence on medical treatments and fertility management are reviewed, including special considerations regarding long-term follow-up of metabolic and psychiatric comorbidities and pregnancy in women with PCOS. Here we summarize the recommendations from a Nordic perspective.

Copper in Gynecological Diseases

Copper (Cu) is an essential micronutrient for the correct development of eukaryotic organisms. This metal plays a key role in many cellular and physiological activities, including enzymatic activity, oxygen transport, and cell signaling. Although the redox activity of Cu is crucial for enzymatic reactions, this property also makes it potentially toxic when found at high levels. Due to this dual action of Cu, highly regulated mechanisms are necessary to prevent both the deficiency and the accumulation of this metal since its dyshomeostasis may favor the development of multiple diseases, such as Menkes' and Wilson's diseases, neurodegenerative diseases, diabetes mellitus, and cancer. As the relationship between Cu and cancer has been the most studied, we analyze how this metal can affect three fundamental processes for tumor progression: cell proliferation, angiogenesis, and metastasis. Gynecological diseases are characterized by high prevalence, morbidity, and mortality, depending on the case, and mainly include benign and malignant tumors. The cellular processes that promote their progression are affected by Cu, and the mechanisms that occur may be similar. We analyze the crosstalk between Cu deregulation and gynecological diseases, focusing on therapeutic strategies derived from this metal.

Asprosin levels in women with and without the polycystic ovary syndrome: a systematic review and meta-analysis

Objective: This systematic review and meta-analysis aimed at summarizing the evidence concerning circulating asprosin, and related endocrine and metabolites in women with and without the polycystic ovary syndrome (PCOS).Method: We performed a comprehensive literature search in Pubmed, Web of Science, Scielo, and Chinese National Knowledge Infrastructure for studies published until May 20, 2022, that evaluated circulating asprosin levels in women with and without PCOS, regardless of language. The quality of studies was assessed with the Newcastle-Ottawa Scale. Random-effects models were used to estimate mean differences (MD) or standardized MD (SMD) and their 95% confidence interval (CI).Results: We evaluated eight studies reporting 1,050 PCOS cases and 796 controls of reproductive age. Participants with PCOS were younger (MD = -2.40 years, 95% CI -2.46 to -2.33), with higher values of asprosin (SMD = 2.57, 95% CI 1.64-3.50), insulin (SMD = 2.73, 95% CI 1.18-4.28), homeostatic model assessment of insulin resistance (SMD = 2.70, 95% CI 0.85-4.55), luteinizing hormone (SMD = 2.33, 95% CI 0.60-4.06), total testosterone (SMD = 4.06, 95% CI 1.89-6.22), dehydroepiandrosterone sulfate (SMD = 2.38, 95% CI 0.37-4.40), and triglycerides (SMD = 1.20, 95% CI 0.13 to 2.27). Moreover, PCOS women had lower circulating levels of sex hormone-binding globulin (SMD = -3.36, 95% CI -4.92 to -1.80), and high-density lipoprotein-cholesterol (SMD = -0.85, 95% CI -1.69 to -0.01); with no significant differences observed for glucose, total cholesterol, and low-density lipoprotein-cholesterol levels.Conclusion: Circulating asprosin levels were significantly higher in women with PCOS as compared to those without the syndrome.

PCOS during the menopausal transition and after menopause: a systematic review and meta-analysis

BACKGROUND

Current knowledge about the consequences of PCOS during the late reproductive years and after menopause is limited.

OBJECTIVE AND RATIONALE

We performed a systematic review and meta-analysis of data on the pathophysiology, clinical manifestations, diagnosis, prognosis, and treatment of women ≥45 years of age-peri- or postmenopausal-with PCOS.

SEARCH METHODS

Studies published up to 15 April 2023, identified by Entrez-PubMed, EMBASE, and Scopus online facilities, were considered. We included cross-sectional or prospective studies that reported data from peri- or postmenopausal patients with PCOS and control women with a mean age ≥45 years. Three independent researchers performed data extraction. Meta-analyses of quantitative data used random-effects models because of the heterogeneity derived from differences in study design and criteria used to define PCOS, among other confounding factors. Sensitivity analyses restricted the meta-analyses to population-based studies, to studies including only patients diagnosed using the most widely accepted definitions of PCOS, only menopausal women or only women not submitted to ovarian surgery, and studies in which patients and controls presented with similar indexes of weight excess. Quality of evidence was assessed using the GRADE system.

OUTCOMES

The initial search identified 1400 articles, and another six were included from the reference lists of included articles; 476 duplicates were deleted. We excluded 868 articles for different reasons, leaving 37 valid studies for the qualitative synthesis, of which 28 studies-published in 41 articles-were considered for the quantitative synthesis and meta-analyses. Another nine studies were included only in the qualitative analyses. Compared with controls, peri- and postmenopausal patients with PCOS presented increased circulating total testosterone (standardized mean difference, SMD 0.78 (0.35, 1.22)), free androgen index (SMD 1.29 (0.89, 1.68)), and androstenedione (SMD 0.58 (0.23, 0.94)), whereas their sex hormone-binding globulin was reduced (SMD -0.60 (-0.76, -0.44)). Women with PCOS showed increased BMI (SMD 0.57 (0.32, 0.75)), waist circumference (SMD 0.64 (0.42, 0.86)), and waist-to-hip ratio (SMD 0.38 (0.14, 0.61)) together with increased homeostasis model assessment of insulin resistance (SMD 0.56 (0.27, 0.84)), fasting insulin (SMD 0.61 (0.38, 0.83)), fasting glucose (SMD 0.48 (0.29, 0.68)), and odds ratios (OR, 95% CI) for diabetes (OR 3.01 (1.91, 4.73)) compared to controls. Women with PCOS versus controls showed decreased HDL concentrations (SMD -0.32 (-0.46, -0.19)) and increased triglycerides (SMD 0.31 (0.16, 0.46)), even though total cholesterol and LDL concentrations, as well as the OR for dyslipidaemia, were similar to those of controls. The OR for having hypertension was increased in women with PCOS compared with controls (OR 1.79 (1.36, 2.36)). Albeit myocardial infarction (OR 2.51 (1.08, 5.81)) and stroke (OR 1.75 (1.03, 2.99)) were more prevalent in women with PCOS than controls, the ORs for cardiovascular disease as a whole, coronary artery disease as a whole, breast cancer and age at menopause, were similar in patients and controls. When restricting meta-analysis to studies in which women with PCOS and controls had a similar mean BMI, the only difference that retained statistical significance was a decrease in HDL-cholesterol concentration in the former and, in the two studies in which postmenopausal women with PCOS and controls had similar BMI, patients presented with increased serum androgen concentrations, suggesting that hyperandrogenism persists after menopause, regardless of obesity.

WIDER IMPLICATIONS

Hyperandrogenism appeared to persist during the late-reproductive years and after menopause in women with PCOS. Most cardiometabolic comorbidities were driven by the frequent coexistence of weight excess and PCOS, highlighting the importance of targeting obesity in this population. However, the significant heterogeneity among included studies, and the overall low quality of the evidence gathered here, precludes reaching definite conclusions on the issue. Hence, guidelines derived from adequately powered prospective studies are definitely needed for appropriate management of these women.

Overactivation of GnRH neurons is sufficient to trigger polycystic ovary syndrome-like traits in female mice

BACKGROUND

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder leading to anovulatory infertility. Abnormalities in the central neuroendocrine system governed by gonadotropin-releasing hormone (GnRH) neurons might be related to ovarian dysfunction in PCOS, although the link in this disordered brain-to-ovary communication remains unclear. Here, we manipulated GnRH neurons using chemogenetics in adult female mice to unveil whether chronic overaction of these neurons would trigger PCOS-like hormonal and reproductive impairments.

METHODS

We used adult Gnrh1cre female mice to selectively target and express the designer receptors exclusively activated by designer drugs (DREADD)-based chemogenetic tool hM3D(Gq) in hypophysiotropic GnRH neurons. Chronic chemogenetic activation protocol was carried out with clozapine N-oxide (CNO) i.p. injections every 48 h over a month. We evaluated the reproductive and hormonal profile before, during, and two months after chemogenetic manipulations.

FINDINGS

We discovered that the overactivation of GnRH neurons was sufficient to disrupt reproductive cycles, promote hyperandrogenism, and induce ovarian dysfunction. These PCOS features were detected with a long-lasting neuroendocrine dysfunction through abnormally high luteinizing hormone (LH) pulse secretion. Additionally, the GnRH-R blockade prevented the establishment of long-term neuroendocrine dysfunction and androgen excess in these animals.

INTERPRETATION

Taken together, our results show that hyperactivity of hypothalamic GnRH neurons is a major driver of reproductive and hormonal impairments in PCOS and suggest that antagonizing the aberrant GnRH signaling could be an efficient therapeutic venue for the treatment of PCOS.

Obesity and Hyperandrogenemia in Polycystic Ovary Syndrome: Clinical Implications

Polycystic ovary syndrome (PCOS) is often accompanied with metabolic disturbances attributed to androgen excess and obesity, but the contribution of each has not been defined, and the occurrence of metabolic disturbances is usually not investigated. Ninety-nine women with PCOS and forty-one without PCOS were evaluated. The clinical biomarkers of alterations related to glucose (glucose, insulin, and clamp-derived glucose disposal - M), liver (aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyl transferase), and endothelium (arginine, asymmetric dymethylarginine, carotid intima-media thickness, and flow-mediated dilation) metabolism were measured; participants were categorized into four groups according to their obesity (OB) and hyperandrogenemia (HA) status as follows: Healthy (no-HA, lean), HA (HA, lean), OB (no-HA, OB), and HAOB (HA, OB). Metabolic disturbances were very frequent in women with PCOS (≈70%). BMI correlated with all biomarkers, whereas free testosterone (FT) correlated with only glucose- and liver-related indicators. Although insulin sensitivity and liver enzymes were associated with FT, women with obesity showed lower M (coef = 8.56 - 0.080(FT) - 3.71(Ob); p < 0.001) and higher aspartate aminotransferase (coef = 26.27 + 0.532 (FT) + 8.08 (Ob); p = 0.015) than lean women with the same level of FT. Women with obesity showed a higher risk of metabolic disorders than lean women, independent of hyperandrogenemia. Clinicians are compelled to look for metabolic alterations in women with PCOS. Obesity should be treated in all cases, but hyperandrogenemia should also be monitored in those with glucose-or liver-related disturbances.

The impact of metformin with or without lifestyle modification versus placebo on polycystic ovary syndrome: a systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

Available evidence has shown that metformin improves insulin sensitivity and weight management in polycystic ovary syndrome (PCOS). Nevertheless, key knowledge gaps remain regarding its efficacy and the specific outcomes in this population. This review evaluates the effectiveness of metformin and lifestyle modification compared with placebo in the management of PCOS and will inform the forthcoming, 2023 evidence-based PCOS guidelines.

DESIGN

Systematic review and meta-analysis of the literature.

METHODS

A search was performed in MEDLINE, EMBASE, PsycINFO, All EBM, and CINAHL. The review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and included randomized controlled trials published in English through July 2022.

RESULTS

Moderate certainty of evidence showed a larger reduction of body mass index (BMI) (mean difference [MD] -0.53, 95% confidence interval [CI] -0.95 to -0.12 kg/m2), homeostatic model assessment for insulin resistance (MD -0.50, 95% CI -0.91 to -0.09) (critical outcomes), and fasting glucose (MD -0.13, 95% CI -0.19 to -0.07 mmol/L) with metformin compared to placebo with increased mild gastrointestinal adverse effects (odds ratio [OR] 7.67, 95% CI 2.74-21.46). Low certainty of evidence showed a larger reduction of waist-hip ratio (MD -0.02, 95% CI -0.03 to -0.00), total cholesterol (MD -0.24, 95% CI -0.43 to -0.05 mmol/L), low-density lipoprotein (MD -0.16, 95% CI -0.30 to -0.01 mmol/L), and triglycerides (MD -0.11, 95% CI -0.20 to -0.02 mmol/L) with metformin than placebo.

CONCLUSIONS

Metformin should be considered an efficacious adjunct to lifestyle interventions in adults with PCOS, especially for those with a higher BMI, to improve weight loss, insulin resistance, and lipids.

Diabetes detection in women with gestational diabetes and polycystic ovarian syndrome

Gestational diabetes mellitus (GDM) and polycystic ovarian syndrome (PCOS) represent two of the highest risk factors for development of type 2 diabetes mellitus in young women. As these increasingly common conditions generally affect younger women, early detection of dysglycemia is key if preventative measures are to be effective. While international guidance recommends screening for type 2 diabetes, current screening strategies suffer from significant challenges.First, guidance lacks consensus in defining which tests to use and frequency of monitoring, thereby sending mixed messages to healthcare professionals.Second, conformity to guidance is poor, with only a minority of women having tests at the recommended frequency (where specified). Approaches to improve conformity have focused on healthcare related factors (largely technology driven reminder systems), but patient factors such as convenience and clear messaging around risk have been neglected.Third, and most critically, current screening strategies are too generic and rely on tests that become abnormal far too late in the trajectory towards dysglycemia to offer opportunities for effective preventative measures. Risk factors show wide interindividual variation, and insulin sensitivity and β cell function are often abnormal during pre-diabetes stage, well before frank diabetes.New, consistent, targeted screening strategies are required that incorporate early, prevention focused testing and personalised risk stratification.

AMH as part of the diagnostic PCOS workup in large epidemiological studies

OBJECTIVES

Previous studies have shown good correlation between polycystic ovarian morphology (PCOM) and serum anti-Müllerian hormone (AMH) levels. We evaluated the utility of AMH as a surrogate for PCOM as a part of the polycystic ovary syndrome (PCOS) diagnosis by describing how the use of different AMH cut-off values would change the prevalence of PCOS.

METHODS

A general population-based birth cohort study. Anti-Müllerian hormone concentrations were measured from serum samples taken at age 31 years (n = 2917) using the electrochemiluminescence immunoassay (Elecsys). Anti-Müllerian hormone data were combined with data on oligo/amenorrhoea and hyperandrogenism to identify women with PCOS.

RESULTS

The addition of AMH as a surrogate marker for PCOM increased the number of women fulfilling at least two PCOS features in accordance with the Rotterdam criteria. The prevalence of PCOS was 5.9% when using the AMH cut-off based on the 97.5% quartile (10.35 ng/mL) and 13.6% when using the recently proposed cut-off of 3.2 ng/mL. When using the latter cut-off value, the distribution of PCOS phenotypes A, B, C, and D was 23.9%, 4.7%, 36.6%, and 34.8%, respectively. Compared with the controls, all PCOS groups with different AMH concentration cut-offs showed significantly elevated testosterone (T), free androgen index (FAI), luteinizing hormone (LH), LH/follicle-stimulating hormone (FSH) ratio, body mass index (BMI), waist circumference, and homoeostatic model assessment of insulin resistance (HOMA-IR) values, as well as significantly decreased sex hormone-binding globulin (SHBG) values.

CONCLUSIONS

Anti-Müllerian hormone could be useful surrogate for PCOM in large data sets, where transvaginal ultrasound is not feasible, to aid the capturing of women with typical PCOS characteristics. Anti-Müllerian hormone measurement from archived samples enables retrospective PCOS diagnosis when combined with oligo/amenorrhoea or hyperandrogenism.

Transcutaneous auricular vagus nerve stimulation as a potential novel treatment for polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of childbearing age. The etiology of PCOS is multifactorial, and current treatments for PCOS are far from satisfactory. Recently, an imbalanced autonomic nervous system (ANS) with sympathetic hyperactivity and reduced parasympathetic nerve activity (vagal tone) has aroused increasing attention in the pathogenesis of PCOS. In this paper, we review an innovative therapy for the treatment of PCOS and related co-morbidities by targeting parasympathetic modulation based on non-invasive transcutaneous auricular vagal nerve stimulation (ta-VNS). In this work, we present the role of the ANS in the development of PCOS and describe a large number of experimental and clinical reports that support the favorable effects of VNS/ta-VNS in treating a variety of symptoms, including obesity, insulin resistance, type 2 diabetes mellitus, inflammation, microbiome dysregulation, cardiovascular disease, and depression, all of which are also commonly present in PCOS patients. We propose a model focusing on ta-VNS that may treat PCOS by (1) regulating energy metabolism via bidirectional vagal signaling; (2) reversing insulin resistance via its antidiabetic effect; (3) activating anti-inflammatory pathways; (4) restoring homeostasis of the microbiota-gut-brain axis; (5) restoring the sympatho-vagal balance to improve CVD outcomes; (6) and modulating mental disorders. ta-VNS is a safe clinical procedure and it might be a promising new treatment approach for PCOS, or at least a supplementary treatment for current therapeutics.

No difference in morbidity between perimenopausal women with PCOS with and without previous wedge resection

OBJECTIVE

Polycystic ovary syndrome (PCOS), affecting more than every 10th woman of reproductive age, is associated with increased risk factors for cardiovascular disease (CVD). Most knowledge regarding longtime consequences concerning morbidity is based on women where ovarian wedge resection (WR) was used as a surgical treatment, a method not used today. The aim of this study was to compare women with PCOS who had and had not undergone WR, regarding risk factors for CVD. The hypothesis was that women who had undergone WR had a more severe PCOS phenotype, and that this cohort thus had more associated CVD risk factors compared with women diagnosed through non-invasive methods.

STUDY DESIGN

A cross-sectional study was performed. A PCOS cohort who underwent WR in the 1950-60 s (n = 27) were compared with a PCOS cohort diagnosed by NIH-criterions in the 1990s without WR (n = 32). Both cohorts were examined at perimenopausal age.

RESULTS

No differences were seen in prevalence of hypertension, obesity or type 2 diabetes mellitus (T2DM) between the women with PCOS with or without WR, respectively. The results were persistent irrespective of the lower mean BMI in the WR group, 26.4 vs. 30.7 kg/m², p = 0.01. In the stratified group of overweight and obese, there was no difference in T2DM 27% vs 25% or hypertension 27% vs 25%, in WR and non-WR women with PCOS, respectively. The cohort diagnosed through WR had higher free androgen index (6.3 vs. 2.1, p < 0.01) and total testosterone (2.20 vs. 0.99 nmol/L, p < 0.01).

CONCLUSION

No differences in CVD risk factors were found in perimenopausal women with PCOS with or without a previous WR, and irrespective of body weight. The results indicate that CVD morbidity and mortality from studies in women with PCOS who have undergone WR are generalizable to women with PCOS who have not undergone WR.

Oral and Vaginal Hormonal Contraceptives Induce Similar Unfavorable Metabolic Effects in Women with PCOS: A Randomized Controlled Trial

This clinical trial aims to compare hormonal and metabolic changes after a 9-week continuous use of oral or vaginal combined hormonal contraceptives (CHCs) in women with polycystic ovary syndrome (PCOS). We recruited 24 women with PCOS and randomized them to use either combined oral (COC, n = 13) or vaginal (CVC, n = 11) contraception. At baseline and 9 weeks, blood samples were collected and a 2 h glucose tolerance test (OGTT) was performed to evaluate hormonal and metabolic outcomes. After treatment, serum sex hormone binding globulin (SHBG) levels increased (p < 0.001 for both groups) and the free androgen index (FAI) decreased in both study groups (COC p < 0.001; CVC p = 0.007). OGTT glucose levels at 60 min (p = 0.011) and AUCglucose (p = 0.018) increased in the CVC group. Fasting insulin levels (p = 0.037) increased in the COC group, and insulin levels at 120 min increased in both groups (COC p = 0.004; CVC p = 0.042). There was a significant increase in triglyceride (p < 0.001) and hs-CRP (p = 0.032) levels in the CVC group. Both oral and vaginal CHCs decreased androgenicity and tended to promote insulin resistance in PCOS women. Larger and longer studies are needed to compare the metabolic effects of different administration routes of CHCs on women with PCOS.

The role of obstetrician-gynecologists and reproductive endocrinologists in the blood glucose management of polycystic ovary syndrome

Background: This study aimed to compare the differences between reproductive endocrinologists (Repro-Endo) and obstetricians-gynecologists (Ob-Gyn; non-reproductive medicine specialty) in diagnosing, evaluating, and treating PCOS women with insulin resistance (IR).Methods: Repro-Endo and Ob-Gyn in China participated in this survey, and their responses were analyzed using χ² tests, Fisher exact tests, and multivariable logistic regression analysis.Results: The study analyzed 2412 survey responses (92.3% OB-Gyn; 98.5% women). Physician's age, hospital grade, specialty, and the number of PCOS patients who visit the physicians, revealed that Repro-Endo participants were more likely to suggest an oral glucose tolerance test (OR, 1.727; 95% CI, 1.272-2.345) as their first choice than Ob-Gyn participants. The most common treatments for patients with PCOS were lifestyle modification (>95%) and metformin use (>80%). More Repro-Endo participants prescribed metformin at a dose of 1.5 g/day compared with OB-Gyn (46.5% vs. 23.5%), and more OB-Gyn participants reported being unclear about the appropriate dosage of metformin for patients with obesity and PCOS (12.5% vs. 1.6%).Conclusion: This survey identified knowledge gaps in metabolic screening for patients with IR and PCOS. Similarly, it highlights the need to improve IR management education for physicians caring for PCOS women.

Estimation of renin and d-dimer levels in women with polycystic ovary disease with or without coronavirus infection

Background and objective: Polycystic ovarian syndrome (PCOS) is a common endocrinologic disorder among women of childbearing age. Coronavirus disease 2019 (COVID-19) is an acute respiratory disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This study aimed to determine the levels of renin, d-dimer, and some relevant biomarkers in patients with PCOS (with and without COVID-19) compared with non-PCOS patients (with and without COVID-19). Methods: This cross-sectional study included 120 women [80 PCOS women (40 with COVID-19 and 40 without COVID-19) and 40 non-PCOS women (20 with COVID-19 and 20 without)] with age range of 15–40 years old. Blood samples were collected from participants, and biochemical assays were carried out. Renin and d-dimer levels were determined using the enzyme-linked-immunosorbent-assay (ELISA), lipid-profile and fasting blood glucose concentrations were assessed by using the colorimetric methods, and hormones were evaluated by VIDAS. Results: Renin and d-dimer levels were found to be significantly higher in PCOS-women groups compared to non-PCOS group. In addition, the results showed that hormones, fasting blood glucose, and lipid-profile are significantly increased in PCOS patients compared to non-PCOS women, while high-density-lipoprotein and follicle-stimulating-hormone levels were low when comparing PCOS patients with non-PCOS ones. The results also showed that a highly significant increase in renin and d-dimer levels can be detected in PCOS patients with COVID-19. Conclusions: In the present study, we found there is a possible relationship between renin and d-dimer in PCOS patients who are also COVID-19 infected.

Polycystic ovary syndrome and leukocyte telomere length: cross-sectional and longitudinal changes

OBJECTIVE

Telomeres are DNA-protein complexes that protect chromosome ends from DNA damage and are surrogate biomarkers of cellular aging. Current evidence, almost entirely from cross-sectional observations, supports negative associations between leukocyte telomere length (LTL) and adverse lifestyle factors and cardiometabolic risk factors. Polycystic ovary syndrome (PCOS), the most common gynecological endocrine disorder, is associated with inflammation and oxidative stress, both factors associated with accelerated telomere attrition. We therefore hypothesized that LTL would be shorter and decrease more rapidly in women with PCOS in comparison to a control population.

DESIGN

This is a population-based cohort study comprising women of Northern Finland Birth Cohort 1966, with clinical examinations at ages 31 and 46. The sample included self-reported PCOS (age 31, n = 190; age 46, n = 207) and referent women (age 31, n = 1054; age 46, n = 1324) with data on LTL.

METHODS

The association between LTL and PCOS at ages 31 and 46 was analyzed by linear regression models adjusted for BMI, smoking, alcohol consumption and socioeconomic status at the corresponding age.

RESULTS

Women with PCOS had similar mean LTL at ages 31 and 46 (P > 0.4 for both). The mean LTL change between ages 31 and 46 did not differ between groups (P = 0.19). However, we observed a significant LTL attrition between ages 31 and 46 in the reference population (P < 0.001), but not in women with PCOS (P = 0.96).

CONCLUSIONS

This finding may suggest a difference in the LTL attrition rate in women with PCOS, an unexpected finding that might affect their risk of age-related disease. Further research is needed to clarify the underlying mechanisms.

The impact of ageing and menopause in women with polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a common hormonal, metabolic and reproductive disorder. Women with PCOS at reproductive age have increased risk and prevalence of prediabetes and diabetes and have multiple risk factors for cardiometabolic disease and other comorbidities such as obstructive sleep apnoea, endometrial cancer and mood disorders, which contribute to the overall health burden of the syndrome. However, little is known about the impact of PCOS on long-term health in ageing women. In this review, we aimed to give an updated overview regarding the long-term health outcomes of PCOS and their clinical implications in peri- and postmenopause. The PCOS phenotype ameliorates with ageing and limited available data suggest that there is no further deterioration in cardiometabolic profile in women with PCOS after menopause. Accordingly, the risk of cardiovascular disease in ageing women with PCOS seems to be no different from those without PCOS and lower than previously anticipated based on their risk during reproductive years. Regarding other comorbidities including sleep apnoea, mood disorders and endometrial cancer, it is difficult to determine the true risk in older women with PCOS due to the confounding factors and lack of long-term cohort studies. Large, prospective studies on community-based and well-phenotyped PCOS cohorts with extended follow-up into late menopause are needed to confirm these findings.

A genome-wide cross-trait analysis identifies shared loci and causal relationships of type 2 diabetes and glycaemic traits with polycystic ovary syndrome

AIMS/HYPOTHESIS

The link underlying abnormal glucose metabolism, type 2 diabetes and polycystic ovary syndrome (PCOS) that is independent of BMI remains unclear in observational studies. We aimed to clarify this association using a genome-wide cross-trait approach.

METHODS

Summary statistics from the hitherto largest genome-wide association studies conducted for type 2 diabetes, type 2 diabetes mellitus adjusted for BMI (T2DM_adjBMI), fasting glucose, fasting insulin, 2h glucose after an oral glucose challenge (all adjusted for BMI), HbA_1c and PCOS, all in populations of European ancestry, were used. We quantified overall and local genetic correlations, identified pleiotropic loci and expression-trait associations, and made causal inferences across traits.

RESULTS

A positive overall genetic correlation between type 2 diabetes and PCOS was observed, largely influenced by BMI (r_g=0.31, p=1.63×10^-8) but also independent of BMI (T2DM_adjBMI-PCOS: r_g=0.12, p=0.03). Sixteen pleiotropic loci affecting type 2 diabetes, glycaemic traits and PCOS were identified, suggesting mechanisms of association that are independent of BMI. Two shared expression-trait associations were found for type 2 diabetes/T2DM_adjBMI and PCOS targeting tissues of the cardiovascular, exocrine/endocrine and digestive systems. A putative causal effect of fasting insulin adjusted for BMI and type 2 diabetes on PCOS was demonstrated.

CONCLUSIONS/INTERPRETATION

We found a genetic link underlying type 2 diabetes, glycaemic traits and PCOS, driven by both biological pleiotropy and causal mediation, some of which is independent of BMI. Our findings highlight the importance of controlling fasting insulin levels to mitigate the risk of PCOS, as well as screening for and long-term monitoring of type 2 diabetes in all women with PCOS, irrespective of BMI.

A machine-learning approach for predicting the effect of carnitine supplementation on body weight in patients with polycystic ovary syndrome

The present study aimed to explore the effect of carnitine supplementation on body weight in patients with polycystic ovary syndrome (PCOS) and predict an appropriate dosage schedule using a machine-learning approach. Data were obtained from literature mining and the rates of body weight change from the initial values were selected as the therapeutic index. The maximal effect (E_max) model was built up as the machine-learning model. A total of 242 patients with PCOS were included for analysis. In the machine-learning model, the E_max of carnitine supplementation on body weight was -3.92%, the ET₅₀ was 3.6 weeks, and the treatment times to realize 25%, 50%, 75%, and 80% (plateau) E_max of carnitine supplementation on body weight were 1.2, 3.6, 10.8, and 14.4 weeks, respectively. In addition, no significant relationship of dose-response was found in the dosage range of carnitine supplementation used in the present study, indicating the lower limit of carnitine supplementation dosage, 250 mg/day, could be used as a suitable dosage. The present study first explored the effect of carnitine supplementation on body weight in patients with PCOS, and in order to realize the optimal therapeutic effect, carnitine supplementation needs 250 mg/day for at least 14.4 weeks.

Value of ultrasonography parameters in diagnosing polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a common endocrinopathy among women of reproductive age associated with hyperandrogenism, oligo-amenorrhea, and infertility. Symptoms and their severity vary among the individuals. If the manifestation is mild, PCOS may remain undiagnosed. In more severe cases, it results in a spectrum of symptoms of metabolic syndrome, insulin resistance, and cardiovascular diseases. The diagnosis is established after a physical examination and evaluating the patient’s hormonal profile. In addition to these required methods, ultrasonographic assessment of the patient’s ovaries is another non-invasive, cheap, and time-saving tool, making the examination more profound and leading to the correct diagnosis. Specific ultrasonographic parameters are used to tell the healthy and polycystic ovaries apart: the ovarian volume (OV), ovarian follicle count, follicle distribution pattern, ovarian stromal echogenicity, and the resistance and pulsatility indices assessed using the Doppler function. This review evaluated the selected articles and ascertained the ultrasonographic parameters that accurately predict PCOS. This systematic review showed that the most valuable ultrasonographic parameters in diagnosing PCOS are the OV and follicle number per ovary.

Prospective Risk of Type 2 Diabetes in Normal Weight Women with Polycystic Ovary Syndrome

Background: Polycystic ovary syndrome (PCOS) is associated with obesity and increased risk for type 2 diabetes (T2D). However, the prospective risk of T2D in normal weight women with PCOS is debated, together with the relevant prospective screening programs for T2D in normal weight women with PCOS. Aim: To review and discuss prospective risk of T2D in normal weight women with PCOS, and to give recommendations regarding prospective screening for T2D in normal weight women with PCOS. Methods: Systematic review. Results: A systematic literature search resulted in 15 published prospective studies (10 controlled studies and 5 uncontrolled studies) regarding risk of T2D in study cohorts of PCOS, where data from normal weight women with PCOS were presented separately. In controlled studies, higher risk of T2D in normal weight women with PCOS compared to controls was reported in 4/10 studies, which included one study where T2D diagnosis was based on glucose measurement, two register-based studies, and one study where diagnosis of T2D was self-reported. Six of the 10 controlled studies reported no increased risk of T2D in normal weight women with PCOS. Four of these studies based the diagnosis of T2D on biochemical measurements, which supported the risk of surveillance bias in PCOS. In uncontrolled studies, 2/5 reported a higher risk of T2D in lean women with PCOS compared to the general population. We discuss the evidence for insulin resistance and β-cell dysfunction in normal weight women with PCOS, and aggravation in the hyperandrogenic phenotype, ageing women, and women with Asian ethnicity. Impaired glucose tolerance could be an important metabolic and vascular risk marker in PCOS. Conclusions: The risk of T2D may be increased in some normal weight women with PCOS. Individual risk markers such as hyperandrogenism, age >40 years, Asian ethnicity, and weight gain should determine prospective screening programs in normal weight women with PCOS.

Can dysglycemia in OGTT be predicted by baseline parameters in patients with PCOS?

Background

Polycystic ovary syndrome (PCOS) is considered a risk factor for the development of type 2 diabetes mellitus (T2DM). However, which is the most appropriate way to evaluate dysglycemia in women with PCOS and who are at increased risk are as yet unclear.

Aim of the study

To determine the prevalence of T2DM, impaired glucose tolerance (IGT), and impaired fasting glucose (IFG) in PCOS women and potential factors to identify those at risk.

Subjects and methods

The oral glucose tolerance test (OGTT), biochemical/hormonal profile, and ovarian ultrasound data from 1614 Caucasian women with PCOS and 362 controls were analyzed in this cross-sectional multicenter study. The data were categorized according to age and BMI.

Results

Dysglycemia (T2DM, IGT, and IFG according to World Health Organization criteria) was more frequent in the PCOS group compared to controls: 2.2% vs 0.8%, P = 0.04; 9.5% vs 7.4%, P = 0.038; 14.2% vs 9.1%, P = 0.002, respectively. OGTT was essential for T2DM diagnosis, since in 88% of them basal glucose values were inconclusive for diagnosis. The presence of either T2DM or IFG was irrespective of age (P = 0.54) and BMI (P = 0.32), although the latter was associated with IGT (P = 0.021). There was no impact of age and BMI status on the prevalence of T2DM or IFG. Regression analysis revealed a role for age, BMI, fat deposition, androgens, and insulin resistance for dysglycemia. However, none of the factors prevailed as a useful marker employed in clinical practice.

Conclusions

One-third of our cohort of PCOS women with either T2DM or IGT displayed normal fasting glucose values but without confirming any specific predictor for dysglycemic condition. Hence, the evaluation of glycemic status using OGTT in all women with PCOS is strongly supported.

Higher Incidence of Metabolic Syndrome in Black Women With Polycystic Ovary Syndrome: A Longitudinal Study

CONTEXT

Cross-sectional studies have identified an increased risk of metabolic syndrome (MetSyn) in women with polycystic ovary syndrome (PCOS), but longitudinal data are limited and primarily include White and European cohorts.

OBJECTIVE

To compare the longitudinal risk of MetSyn in Black and White women with PCOS and to identify potential factors mediating the risk of MetSyn.

METHODS

Longitudinal cohort study with a follow-up of 5.3 years at an academic medical center.

OF

247 adult women with hyperandrogenic PCOS phenotype with 2 or more visits at least 3 years apart. The main outcome measure was incidence of MetSyn in Black and White women with PCOS.

RESULTS

Using a mixed-effects model over time, the incidence of MetSyn was higher in Black women (45.9 ± 4.74 per 100 person-years) than in White women (31.3 ± 3.03 per 100 person-years) (P < .01) after adjusting for age and medication status. This difference persisted among women under age 30. Among Black women who did not have MetSyn at their prior visit, 28.0% had MetSyn at the next visit, compared with 12.1% of White women after adjusting for age and medication status (P < .01). In both races, the model-based estimated rates of MetSyn increased significantly with increase in body mass index and free testosterone.

CONCLUSION

We describe a persistent higher incidence of MetSyn in Black than in White women with PCOS. In addition to early cardiometabolic screening at the time of diagnosis, our findings highlight the need for ongoing and frequent screening in this population.

"I felt like she didn't take me seriously": a multi-methods study examining patient satisfaction and experiences with polycystic ovary syndrome (PCOS) in Canada

Background

Polycystic ovary syndrome (PCOS) is a common and complex condition affecting metabolic, reproductive, cardiovascular, and psychological health in women. Previous studies point to widespread dissatisfaction and delays with the diagnosis of PCOS and a lack of information provision by doctors, with few studies on Canadian populations. This multi-methods study explored the perceptions and experiences of PCOS diagnosis in Canada using an online-distributed survey and follow-up, in-depth, semi-structured phone interviews.

Methods

The online questionnaire was completed by 296 women aged 18–60 with a self-reported diagnosis of PCOS. The survey measured time to diagnosis, number of doctors seen, and information provided. Descriptive statistics, Chi-square tests, Fisher’s exact tests, and Spearman’s rank correlations were used to analyze the sample characteristics and correlations between the demographic factors and the outcome measures. Twenty-five follow-up interviews were held over the phone and analyzed using thematic analysis and interpretive description methodology.

Results

Survey respondents were dissatisfied with the information provided about PCOS (66%), lifestyle management (34%), and medical therapy (38%) at the time of diagnosis. Approximately 34% of respondents waited for more than 2 years and 41% saw 3 or more doctors before attaining diagnosis. Many did not receive any information about lifestyle management (42%) or medical therapy (28%). Interview participants encountered doctors who lacked sufficient knowledge on PCOS to diagnose, chronically dismissed concerns, and did not provide necessary medical information about the condition. Women described benefitting from self-advocation to receive the care they needed from doctors, and self-educating about PCOS using materials they could find online. Younger interview participants whose symptoms began in adolescence would often not understand the significance of symptoms until much later in life, contributing to delayed diagnoses.

Conclusions

Greater education on PCOS for physicians, particularly in primary care, is needed to prevent delayed diagnoses and ensure that patients are provided with reliable medical information about their condition. Greater awareness of PCOS may be necessary for the general population to help women identify symptoms, especially for adolescents and their parental figures.

Pediatric and adult obesity concerns in female health: a Mendelian randomization study

PURPOSE

Adulthood and childhood obesity are both associated with reproductive diseases and gynecological cancers in females. However, the causal factors associated with these observations have yet to be identified. Mendelian randomization is a process that is independent of inverse bias and confounding and can act as a random control trial in which genetic groups are settled during meiosis, thus representing an effective tool with which to investigate causality.

METHODS

We carried out several Mendelian randomization trials based on the combined genetic scores of 75 adult-associated and 15 childhood-associated body mass index (BMI) single nucleotide polymorphisms (SNPs), databases for several gynecological cancers and reproductive diseases from the UK Biobank (with 194,153 participants), using the traditional inverse-variance weighted (IVW) method as the main method.

RESULTS

Elevated adult-associated BMI scores (odds ratio [OR] = 1.003; 95% confidence interval [CI]: 1.001-1.004) and childhood-associated BMI scores (OR = 1.003; 95% CI: 1.001-1.004) were related to a higher risk of the polycystic ovarian syndrome (PCOS), as determined by the traditional IVW method. The random IVW method further revealed a nominal negative causal association between childhood-associated BMI and subsequent endometriosis (OR = 0.995; 95% CI: 0.991-0.999).

CONCLUSIONS

Consistent with observational consequences, our findings indicated that adulthood obesity may play role in the development of PCOS and that childhood obesity can increase the risk of PCOS but may reduce the incidence of endometriosis in later life. Further research is now needed to validate our findings and identify the precise mechanisms involved.

Polycystic ovary syndrome and type 2 diabetes mellitus: A state-of-the-art review

Polycystic ovary syndrome (PCOS) often coexists with a wide spectrum of dysglycemic conditions, ranging from impaired glucose tolerance to type 2 diabetes mellitus (T2D), which occur to a greater extent compared to healthy body mass index-matched women. This concurrence of disorders is mainly attributed to common pathogenetic pathways linking the two entities, such as insulin resistance. However, due to methodological flaws in the available studies and the multifaceted nature of the syndrome, there has been substantial controversy as to the exact association between T2D and PCOS which has not yet been elucidated. The aim of this review is to present the best available evidence regarding the epidemiology of dysglycemia in PCOS, the unique pathophysiological mechanisms underlying the progression of dysglycemia, the most appropriate methods for assessing glycemic status and the risk factors for T2D development in this population, as well as T2D risk after transition to menopause. Proposals for application of a holistic approach to enable optimal management of T2D risk in PCOS are also provided. Specifically, adoption of a healthy lifestyle with adherence to improved dietary patterns, such the Mediterranean diet, avoidance of consumption of endocrine-disrupting foods and beverages, regular exercise, and the effect of certain medications, such as metformin and glucagon-like peptide 1 receptor agonists, are discussed. Furthermore, the maintenance of a healthy weight is highlighted as a key factor in achievement of a significant reduction of T2D risk in women with PCOS.

Adverse Effects of Polycystic Ovarian Syndrome on Pregnancy Outcomes in Women With Frozen-Thawed Embryo Transfer: Propensity Score-Matched Study

PURPOSE

This work aimed to evaluate the adverse effect of polycystic ovary syndrome (PCOS) on pregnancy outcomes of singletons after vitrification in women with frozen-thawed embryo transfer (FET).

METHODS

Patients with/without PCOS who underwent FET from January 2013 and December 2018 were included. Propensity score matching (PSM) was used to reduce the influence of bias. Logistic regression was applied to identify the risk factors of adverse pregnancy outcomes of singletons in women with PCOS.

RESULT

After PSM, the PCOS group had shorter gestational age (P<0.001) and lower newborn birth weight than the non-PCOS group (P=0.045). Compared with the non-PCOS group, the PCOS group had an increased risk of gestational diabetes mellitus (GDM) and pregnancy-induced hypertension (PIH) (P<0.001), placenta and membrane abnormality (P<0.001), stillbirth (P<0.001), neonatal complication (P=0.014), and miscarriage rate (P<0.001). Neonatal complication was associated with parity (adjusted OR=1.202, 95% CI=1.002-1.443, P=0.048) and basal P level (adjusted OR=1.211, 95% CI=1.021-1.436, P=0.028). According to multivariable logistic regression analysis, the miscarriage rate was related to parity (adjusted OR=1.201, 95% CI=1.057-1.166, P=0.005) and basal E2 (adjusted OR=1.002, 95% CI=1.000-1.004, P=0.019) and P levels on the day of embryo transfer (adjusted OR=0.971, 95% CI=0.957-0.985, P<0.001).

CONCLUSIONS

Compared with non-PCOS women, women with PCOS have a higher risk of GDM and PIH, and neonatal complications and therefore require additional care during pregnancy and parturition.

An overview of polycystic ovary syndrome in aging women

The manifestations of polycystic ovary syndrome (PCOS), a ubiquitous reproductive disorder, may vary significantly depending on the severity of a number of endocrine and metabolic changes. Although no diagnostic criteria are presently available for PCOS for perimenopausal and menopausal women, the condition can still be suspected in case of a previous diagnosis of the condition, a chronic history of irregular menstrual cycles and hyperandrogenism, and/or polycystic ovarian morphology during the reproductive period. PCOS is associated with long-term health risks, including obesity, diabetes, hypertension, dyslipidemia, metabolic syndrome and cardiovascular risk factors during reproductive age, especially in patients possessing classic phenotypes. The aim of this review was to outline the available data about the impact of PCOS on long-term health risks after reproductive age in patients with PCOS. Previously, it was assumed that women with PCOS would be more prone to develop cardiometabolic diseases after reproductive age but current data suggest that in accordance with the healing in the phenotypic characteristics of PCOS, no deterioration appears to occur in cardiometabolic health in these patients. While there is substantial evidence for a greater prevalence of abnormal subclinical atherosclerotic markers among younger patients with PCOS, data for older women are insufficient. However, there is also support for an increased risk of endometrial cancer in PCOS patients. Extensive prospective cohort studies in which healthy controls as well as patients with defining PCOS phenotypes are observed and monitored from the early reproductive period into the late postmenopausal period should now be performed in order to clarify morbidities and mortality in aging women with PCOS.

Polycystic Ovary Syndrome, Combined Oral Contraceptives, and the Risk of Dysglycemia: A Population-Based Cohort Study With a Nested Pharmacoepidemiological Case-Control Study

OBJECTIVE

Irregular menstrual cycles are associated with increased cardiovascular mortality. Polycystic ovary syndrome (PCOS) is characterized by androgen excess and irregular menses; androgens are drivers of increased metabolic risk in women with PCOS. Combined oral contraceptive pills (COCPs) are used in PCOS both for cycle regulation and to reduce the biologically active androgen fraction. We examined COCP use and risk of dysglycemia (prediabetes and type 2 diabetes) in women with PCOS.

RESEARCH DESIGN AND METHODS

Using a large U.K. primary care database (The Health Improvement Network [THIN]; 3.7 million patients from 787 practices), we carried out a retrospective population-based cohort study to determine dysglycemia risk (64,051 women with PCOS and 123,545 matched control subjects), as well as a nested pharmacoepidemiological case-control study to investigate COCP use in relation to dysglycemia risk (2,407 women with PCOS with [case subjects] and without [control subjects] a diagnosis of dysglycemia during follow-up). Cox models were used to estimate the unadjusted and adjusted hazard ratio, and conditional logistic regression was used to obtain adjusted odds ratios (aORs).

RESULTS

The adjusted hazard ratio for dysglycemia in women with PCOS was 1.87 (95% CI 1.78-1.97, P < 0.001; adjustment for age, social deprivation, BMI, ethnicity, and smoking), with increased rates of dysglycemia in all BMI subgroups. Women with PCOS and COCP use had a reduced dysglycemia risk (aOR 0.72, 95% CI 0.59-0.87).

CONCLUSIONS

In this study, limited by its retrospective nature and the use of routinely collected electronic general practice record data, which does not allow for exclusion of the impact of prescription-by-indication bias, women with PCOS exposed to COCPs had a reduced risk of dysglycemia across all BMI subgroups. Future prospective studies should be considered for further understanding of these observations and potential causality.

Efficacy of Bushen Huatan Decoction combined with Baduanjin in the treatment of polycystic ovary syndrome with insulin resistance (IR-PCOS), kidney deficiency and phlegm dampness: study protocol for a randomized controlled trial

Background

Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disease in women. Insulin resistance (IR) has emerged as a central contributor to the pathogenesis of this disease. According to traditional Chinese medicine (TCM), kidney deficiency is the main syndrome of PCOS. The deficiency of the kidney cannot vaporize water-dampness, and the retention of water-dampness accumulates into phlegm dampness stagnation, resulting in visceral dysfunction and metabolic disorder. TCM involving syndrome differentiation and treatment is widely used to adjust women’s menstrual cycles. Our patented formula Bushen Huatan Decoction (BSHTD) has been proven to be effective in the clinical treatment of IR-PCOS. Baduanjin also plays an important role in improving metabolic syndrome through lifestyle intervention. This study investigates the clinical efficacy of Bushen Huatan Decoction combined with Baduanjin in IR-PCOS, to form a specific TCM-behaviour intervention plan in the treatment of IR-PCOS.

Methods/design

This is a randomized controlled trial involving 190 participants diagnosed with IR-PCOS. All participants will be randomly allocated into 5 groups: group A will receive metformin; group B, BSHTD; group C, Baduanjin; group D, BSHTD combined with metformin; and group E, BSHTD combined with Baduanjin. One course of treatment lasts 3 months, a total of two courses. The primary outcomes are changes in the homeostatic model assessment of insulin resistance (HOMA-IR) and improvements in the oral glucose tolerance test (OGTT) and insulin-releasing test (INS). The secondary outcomes are improvements in the menstrual cycle, ovulation rate, clinical pregnancy rate, basic serum sex hormone levels, free androgen index (FAI), Ferriman-Gallwey scores, body mass index (BMI) and TCM syndrome scores. The related observation indexes will be collected at baseline, during the process of treatment and at the 6-month follow-up. Simultaneously, close monitoring of possible adverse events will be performed throughout the trial process.

Discussion

This trial will investigate the efficacy of the comprehensive intervention program of Bushen Huatan Decoction combined with Baduanjin on the adjustment of the menstrual cycle, improvement of insulin resistance and correction of glucose metabolism disorder in IR-PCOS patients. It is expected to form an alternative treatment of TCM-behaviour intervention therapy for IR-PCOS and promote the Chinese fitness Qigong Baduanjin in the application of lifestyle diseases.

Ultrasound-guided transvaginal ovarian needle drilling for clomiphene-resistant polycystic ovarian syndrome in subfertile women

BACKGROUND

Ovulatory disturbance is a key diagnostic feature of polycystic ovarian syndrome (PCOS), leading to infertility and correspondingly heavy disease burden. Many therapeutic strategies have been used to induce ovulation for women with PCOS who are infertile. Ultrasound-guided transvaginal ovarian needle drilling (UTND) is a novel surgical method used to induce ovulation for women with clomiphene-resistant PCOS at the outpatient clinic.  OBJECTIVES: To evaluate the efficacy and safety of UTND for subfertile women with clomiphene-resistant PCOS.

SEARCH METHODS

We searched the Cochrane Gynaecology and Fertility Group Specialised Register, CENTRAL, MEDLINE, Embase, and other databases to December 2020. We checked conference abstracts, reference lists, and clinical trials registries. We also contacted experts and specialists in the field for any additional trials .

SELECTION CRITERIA

We planned to include randomised controlled trials comparing UTND to laparoscopic ovarian drilling, and UTND combined with gonadotropins to gonadotropins, in women of reproductive age with clomiphene-resistant PCOS and infertility.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened the trials identified by the search for inclusion, assessed methodological quality and risk of bias, and extracted data. The primary outcomes were live birth rate and incidence of surgical complications (bleeding and infection). Secondary outcomes included pregnancy rate, ovulation rate, and ovarian hyperstimulation syndrome. We planned to calculate odds ratios with 95% confidence intervals for dichotomous data. We would assess overall quality of the evidence by applying the GRADE criteria.

MAIN RESULTS

We did not identify any trials for inclusion in the review. We were unable to assess the benefit or harm of applying UTND for women with clomiphene-resistant PCOS, as no studies could be included in the current review. We moved the previously included trials to studies awaiting classification due to concerns regarding methodology.

AUTHORS' CONCLUSIONS

Since we did not identify any studies for inclusion, we were unable to assess the benefit or harm of applying UTND for women with clomiphene-resistant PCOS.

Risk of type 2 diabetes mellitus in polycystic ovary syndrome is associated with obesity: a meta-analysis of observational studies

PURPOSE

The exact risk of type 2 diabetes mellitus (T2DM) in women with polycystic ovary syndrome (PCOS) is unknown. It is also unclear if obesity independently increases T2DM risk in this population. The aim of this study was to systematically review and synthesize the best available evidence regarding the association between PCOS and T2DM, stratified according to obesity status.

METHODS

A comprehensive search was conducted in PubMed, CENTRAL and Scopus databases up to October 31, 2020. Data are expressed as relative risk (RR) with 95% confidence interval (CI). The I² index was employed for heterogeneity.

RESULTS

The eligibility criteria were fulfilled by 23 studies (319,780 participants; 60,336 PCOS and 8847 type 2 diabetes cases). Women with PCOS demonstrated a higher risk of T2DM than those without PCOS (RR 3.45, 95% CI, 2.95-4.05, p < 0.001; I² 81.6%). This risk remained significant both in studies matched or unmatched for participants' age. With regard to body mass index (BMI), the RR for developing T2DM in obese and non-obese PCOS women compared with their non-PCOS counterparts was 3.24 (95% CI 2.25-4.65; p < 0.001; I² 30.9%) and 1.62 (95% CI 0.14-18.50; p = 0.70; I² 89.9%), respectively. The RR for developing T2DM was 3.85 (95% CI 1.99-7.43; p < 0.001; I² 46.2%) in obese compared with non-obese women with PCOS. This was also the case for overweight compared with lean women with PCOS.

CONCLUSIONS

Women with PCOS present an increased risk of T2DM compared with non-PCOS women only if they are obese/overweight.

Serum asprosin level in different subtypes of polycystic ovary syndrome: a cross-sectional study

OBJECTIVE

Polycystic ovary syndrome can be divided into different subtypes, including insulin resistance and hyperandrogenism. The aim of this study was to investigate the relationship between serum asprosin levels and polycystic ovary syndrome subtypes.

METHODS

A total of 93 women with polycystic ovary syndrome and 77 healthy women as controls were selected for this study. The clinical and laboratory data were compared between the Polycystic ovary syndrome group and the control group. The Polycystic ovary syndrome group was further divided into subgroups: (1) women with or without hyperandrogenism (polycystic ovary syndrome hyperandrogenism and Polycystic ovary syndrome none-hyperandrogenism, respectively) and (2) women with or without insulin resistance (polycystic ovary syndrome insulin resistance and Polycystic ovary syndrome none-insulin resistance, respectively). Serum asprosin was measured by using enenzyme-linked immunosorbent assay.

RESULTS

Serum asprosin levels showed no significant difference between the polycystic ovary syndrome and control groups. However, it was significantly lower in the Polycystic ovary syndrome HA and insulin resistance groups compared with the respective Polycystic ovary syndrome none-hyperandrogenism and none-insulin resistance groups (p<0.05). In the Polycystic ovary syndrome group, serum asprosin was negatively correlated with body mass index, luteinizing hormone, testosterone, basal antral follicles, fasting insulin, homeostatic model assessment of insulin resistance, and triglycerides. After adjusting for body mass index, the correlations were not significant, and asprosin was only positively correlated with prolactin (prolactin; r=0.426, p<0.001).

CONCLUSION

Our study shows that women with polycystic ovary syndrome hyperandrogenism or insulin resistance exhibit significantly lower serum asprosin levels compared with controls, and the lower asprosin level directly correlated with prolactin level.

Weight Management in Adolescents with Polycystic Ovary Syndrome

PURPOSE OF REVIEW

Polycystic ovary syndrome (PCOS) is a common condition that clinically presents during adolescence. PCOS is associated with increased rates of overweight and obesity, as well as higher rates of metabolic disease, especially type 2 diabetes. Weight loss decreases PCOS symptoms and risk for metabolic disease. The goal of this review is to evaluate recent studies describing the hormonal, metabolic, and weight effects of different weight loss strategies: dietary, physical activity, pharmacotherapy, bariatric surgery, mood modification, and sleep.

RECENT FINDINGS

Calorie restriction continues to be supported as the primary nutrition intervention to achieve weight loss in individuals with PCOS, and a dietary macronutrient composition with lower compared to higher glycemic carbohydrates may be more effective. There is limited data that vitamins, nutraceuticals, and probiotics may improve hormonal and metabolic outcomes. Most types of physical activity are effective in improving outcomes in PCOS and lowering weight. Whereas there are promising data on anti-obesity medications such as glucagon-like peptide-1 receptor agonists in adults with PCOS and adolescents with obesity, further work is needed to know if these therapies are effective in youth with PCOS. Research is lacking on the effectiveness of other anti-obesity medications in PCOS. Bariatric surgery is especially promising for decreasing weight in adults and youth, and reversing type 2 diabetes in youth, though PCOS data are lacking. Treatment of depression in adolescents with insulin resistance and women with PCOS is associated with improved weight loss. Adolescents with PCOS and obesity may have greater sleep-related risks including circadian misalignment and obstructive sleep apnea, interventions for which have not yet been conducted. Clinical trials on weight loss strategies in adolescents with PCOS remain limited, with most information inferred from studies in women with PCOS or adolescents with obesity. However, there are multiple options to optimize weight loss in dietary, activity, pharmacotherapy, bariatric surgery, mood modification, and sleep domains.

Natural History of Polycystic Ovary Syndrome and New Advances in the Epidemiology

Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women, affecting up to 15% of the female population. The natural history of the syndrome is complex, including both androgen exposure in early life and adiposity-driven dysfunction involving also dysregulated, also involving altered hypothalamus-ovarian crosstalk. The manifestations can arise as early as childhood or puberty onward, suggesting that genetic susceptibility is an important etiological factor. In adulthood, women with PCOS present with reproductive, metabolic, and psychological health issues at a population-based level. Epidemiological studies on large datasets offer an excellent opportunity to evaluate health effects and costs related to the syndrome. Hospital or insurance-based datasets are also available; however, the results are not representative of the female population in the community. More longitudinal studies spanning from early childhood to late adulthood are needed to assess the long-term health impact and early manifestations of PCOS. Moreover, the identification of women with PCOS from large datasets can be expensive. Self-reported symptoms or PCOS diagnosis may offer a feasible approach.

Higher risk of type 2 diabetes in women with hyperandrogenic polycystic ovary syndrome

OBJECTIVE

To assess the risk of type 2 diabetes (T2D) in women with polycystic ovary syndrome (PCOS) in relation to body mass index (BMI) and the hyperandrogenic (HA) PCOS phenotype.

DESIGN

Population-based cohort study.

SETTING

Data from six Swedish national registers, with participants being followed for a maximum of 19 years.

PATIENT(S)

All women with an International Statistical Classification of Diseases and Related Health Problems, version 10, diagnosis of PCOS, androgen excess, or anovulatory infertility born between 1950 and 1999 (n = 52,535) were identified in the Patient Register. The HA PCOS phenotype was defined by two filled prescriptions for anti-androgenic drugs. For each woman with PCOS, five control women (n = 254,624) were randomly chosen from the Total Population Register, matched for age and geographic area.

INTERVENTION(S)

No interventions were performed.

MAIN OUTCOME MEASURE(S)

International Statistical Classification of Diseases and Related Health Problems, version 10, diagnosis of T2D or prescription of antidiabetic treatment other than metformin.

RESULT(S)

The cumulative incidence rates of T2D were 1.3%, 4.4%, and 14.2% in controls (non-PCOS women) and women with normoandrogenic (NA) and HA PCOS, respectively. After adjustment for BMI, women with PCOS had a twofold higher rate of T2D than non-PCOS women (adjusted hazard ratio, 2.52 [95% confidence interval, 2.15-2.96]). Women with HA PCOS had a higher rate of T2D than those with NA PCOS (adjusted hazard ratio, 3.86 [95% confidence interval, 3.16-4.72]).

CONCLUSION(S)

Polycystic ovary syndrome is an independent risk factor for T2D, even after adjustment for BMI. Women with the HA PCOS phenotype face an even higher risk of T2D than those with the NA PCOS phenotype.

Polycystic ovary syndrome in pediatric obesity and diabetes

INTRODUCTION

Polycystic ovary syndrome is characterized by anovulation (amenorrhea, oligomenorrhea, irregular menstrual cycles) combined with symptoms of androgen excess (hirsutism, acne, alopecia). The clear definition and diagnosis in adolescents could be challenging considering that most of symptoms occur as part of the expected physiological hormonal imbalance of puberty. Therefore, different diagnostic criteria have been elaborated. Polycystic ovary syndrome could be associated to obesity, diabetes mellitus, and metabolic syndrome. In adolescents with polycystic ovary syndrome, adiposity is associated with higher androgen concentrations and greater menstrual irregularity. Polycystic ovary syndrome in youth is considered a risk factor for type 2 diabetes mellitus in adulthood. On the other hand, increased prevalence of polycystic ovary syndrome has been shown in type 1 diabetes mellitus.

EVIDENCE

The treatment of polycystic ovary syndrome in adolescents is controversial considering that adequate trials are lacking. First line treatment comprises lifestyle modification (preferably multicomponent including diet, exercise and behavioural strategies) that should be recommended overall in the patients with polycystic ovary syndrome and overweight, central obesity and insulin resistance. Beyond non-pharmacological therapy, pharmacological agents include combined hormonal contraceptives, metformin and antiandrogens, used separately or in combination. The aim of therapy is to bring back ovulation, to normalize menses, to reduce hirsutism and acne, to reduce weight. Other important goal is the treatment of hyperlipidaemia and of hyperglycaemia.

CONCLUSIONS

This narrative review aims to review the most pertinent literature about polycystic ovary syndrome in adolescents with obesity or diabetes. We overviewed the diagnostic criteria, the pathophysiology and the possible treatment approaches.

Long-term cardiometabolic disease risk in women with PCOS: a systematic review and meta-analysis

BACKGROUND

Polycystic ovary syndrome (PCOS) is associated with cardiometabolic disease, but recent systematic reviews and meta-analyses of longitudinal studies that quantify these associations are lacking.

OBJECTIVE AND RATIONALE

Is PCOS a risk factor for cardiometabolic disease?

SEARCH METHODS

We searched from inception to September 2019 in MEDLINE and EMBASE using controlled terms (e.g. MESH) and text words for PCOS and cardiometabolic outcomes, including cardiovascular disease (CVD), stroke, myocardial infarction, hypertension (HT), type 2 diabetes (T2D), metabolic syndrome and dyslipidaemia. Cohort studies and case–control studies comparing the prevalence of T2D, HT, fatal or non-fatal CVD and/or lipid concentrations of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and triglycerides (TGs) between women with and without PCOS of ≥18 years of age were eligible for this systematic review and meta-analysis. Studies were eligible regardless of the degree to which they adjusted for confounders including obesity. Articles had to be written in English, German or Dutch. Intervention studies, animal studies, conference abstracts, studies with a follow-up duration less than 3 years and studies with less than 10 PCOS cases were excluded. Study selection, quality assessment (Newcastle–Ottawa Scale) and data extraction were performed by two independent researchers.

OUTCOMES

Of the 5971 identified records, 23 cohort studies were included in the current systematic review. Women with PCOS had increased risks of HT (risk ratio (RR): 1.75, 95% CI 1.42 to 2.15), T2D (RR: 3.00, 95% CI 2.56 to 3.51), a higher serum concentration of TC (mean difference (MD): 7.14 95% CI 1.58 to 12.70 mg/dl), a lower serum concentration of HDL-C (MD: −2.45 95% CI −4.51 to −0.38 mg/dl) and increased risks of non-fatal cerebrovascular disease events (RR: 1.41, 95% CI 1.02 to 1.94) compared to women without PCOS. No differences were found for LDL-C (MD: 3.32 95% CI −4.11 to 10.75 mg/dl), TG (MD 18.53 95% CI −0.58 to 37.64 mg/dl) or coronary disease events (RR: 1.78, 95% CI 0.99 to 3.23). No meta-analyses could be performed for fatal CVD events due to the paucity of mortality data.

WIDER IMPLICATIONS

Women with PCOS are at increased risk of cardiometabolic disease. This review quantifies this risk, which is important for clinicians to inform patients and to take into account in the cardiovascular risk assessment of women with PCOS. Future clinical trials are needed to assess the ability of cardiometabolic screening and management in women with PCOS to reduce future CVD morbidity.

Dietary Patterns with Healthy and Unhealthy Traits Among Overweight/Obese Hispanic Women with or at High Risk for Type 2 Diabetes

Hispanic women are at high risk for type 2 diabetes (T2D), with obesity and unhealthy eating being important contributing factors. A cross-sectional design was used in this study to identify dietary patterns and their associations with diabetes risk factors. Participants completed a culturally adapted Food Frequency Questionnaire capturing intake over the prior 3 months. Overweight/obese Hispanic women (n = 191) with or at risk for T2D were recruited from a community clinic into a weight loss intervention. Only baseline data was used for this analysis. Dietary patterns and their association with diabetes risk factors (age, body mass index, abdominal obesity, elevated fasting blood glucose [FBG], and hemoglobin A1c). An exploratory factor analysis of dietary data adjusted for energy intake was used to identify eating patterns, and Pearson correlation coefficient (r) to assess the association of the eating patterns with the diabetes risk factors. Six meaningful patterns with healthful and unhealthful traits emerged: (1) sugar and fat-laden, (2) plant foods and fish, (3) soups and starchy dishes, (4) meats and snacks, (5) beans and grains, and (6) eggs and dairy. Scores for the "sugar and fat-laden" and "meats and snacks" patterns were negatively associated with age (r = - 0.230, p = 0.001 and r = - 0.298, p < 0.001, respectively). Scores for "plant foods and fish" were positively associated with FBG (r = 0.152, p = 0.037). Being younger may be an important risk factor for a diet rich in sugar and fat; this highlights the need to assess dietary patterns among younger Hispanic women to identify traits potentially detrimental for their health.

Risk of developing major depressive disorder in polycystic ovary syndrome: a retrospective cohort study

This study aimed to investigate the risk of developing major depressive disorder (MDD) in women with polycystic ovary syndrome (PCOS). As a population-based retrospective cohort study based on the Korean National Health Insurance Claims Database and National Health Information Database, newly diagnosed 26,251 women with PCOS with age matched 131,480 women without PCOS from 2007 to 2010 were followed longitudinally and the subsequent occurrence of newly onset MDD was evaluated. The risk of developing MDD in women with PCOS after adjusting for various confounding variables was higher compared to women without PCOS (hazard ratio [HR]1.34, 95% confidence intervals [CI] 1.29-1.40, p<.0001). Stratified by the body mass index, the risk of being admitted to the hospital due to MDD was the highest in the overweight PCOS (HR 2.53, 95% CI 1.71-3.76, p<.0001). The risk of developing MDD was higher in women with PCOS compared to women without PCOS. Maintenance of the appropriate body weight should be emphasised as the hazard ratio of developing MDD was higher in overweight women with PCOS.Impact statementWhat is already known on this subject? PCOS is a multisystem disorder associated with various comorbidities including diabetes mellitus, infertility and endometrial cancer.What do the results of this study add? Women with PCOS showed a higher risk of developing MDD compared to age matched women without PCOS in this multivariate analysis after adjusting for body-mass-index, smoking habit, socio-economic status, residential area, blood glucose, and blood cholesterol. The risk of being admitted to hospital due to MDD was the highest in PCOS with BMI ≥ 25.What are the implications of these findings for clinical practice and/or further research? PCOS should not be considered as a condition confined to ovulatory dysfunction and dermatologic problems, but the higher risk of developing MDD should be recognised. The importance of maintaining an appropriate BMI should be emphasised, as the risk of being admitted to the hospital due to MDD increased in overweight and obese women with PCOS.

Higher blood pressure in normal weight women with PCOS compared to controls

OBJECTIVE

Obesity is considered to be the strongest predictive factor for cardio-metabolic risk in women with polycystic ovary syndrome (PCOS). The aim of the study was to compare blood pressure (BP) in normal weight women with PCOS and controls matched for age and BMI.

METHODS

From a Nordic cross-sectional base of 2615 individuals of Nordic ethnicity, we studied a sub cohort of 793 normal weight women with BMI < 25 kg/m2 (512 women with PCOS according to Rotterdam criteria and 281 age and BMI-matched controls). Participants underwent measurement of BP and body composition (BMI, waist-hip ratio), lipid status, and fasting BG. Data were presented as median (quartiles).

RESULTS

The median age for women with PCOS were 28 (25, 32) years and median BMI was 22.2 (20.7, 23.4) kg/m2. Systolic BP was 118 (109, 128) mmHg in women with PCOS compared to 110 (105, 120) mmHg in controls and diastolic BP was 74 (67, 81) vs 70 (64, 75) mmHg, both P < 0.001. The prevalence of women with BP ≥ 140/90 mmHg was 11.1% (57/512) in women with PCOS vs 1.8% (5/281) in controls, P < 0.001. In women ≥ 35 years the prevalence of BP ≥ 140/90 mmHg was comparable in women with PCOS and controls (12.7% vs 9.8%, P = 0.6). Using multiple regression analyses, the strongest association with BP was found for age, waist circumference, and total cholesterol in women with PCOS.

CONCLUSIONS

Normal weight women with PCOS have higher BP than controls. BP and metabolic screening are relevant also in young normal weight women with PCOS.

Risk of type 2 diabetes is increased in nonobese women with polycystic ovary syndrome: the National Health Insurance Service-National Sample Cohort Study

OBJECTIVE

To investigate the relationship between polycystic ovary syndrome (PCOS) and type 2 diabetes mellitus (T2DM) in Korean women.

DESIGN

Longitudinal case-control study.

SETTING

Not applicable.

PATIENT(S)

PCOS patients aged 15 to 44 years (n = 1,136) and control individuals (n = 5,675), matched 1:5 by age group, income, and region of residence.

INTERVENTION(S)

Not applicable.

MAIN OUTCOME MEASURE(S)

The occurrence of T2DM.

RESULT(S)

In the PCOS and control groups, 15.7% and 14.4%, respectively, were obese (body mass index ≥25 kg/m²). The incidence rate of T2DM was 15.84/1,000 and 5.80/1,000 person-years in the PCOS and control groups, respectively. The unadjusted hazard ratio (HR) of T2DM in women with PCOS was 2.6-fold higher than that in control individuals. Women with PCOS still had a higher HR of T2DM than did control individuals after adjustment for body mass index, family history of T2DM, physical exercise level, and total cholesterol. PCOS was significantly associated with T2DM in women both with and without obesity.

CONCLUSION(S)

PCOS is independently associated with an increased incidence of T2DM in both obese and nonobese women. Screening for T2DM should be considered for both obese and nonobese women with PCOS in Korea.

White, brown, and bone marrow adipose tissue behavior in DHEA-induced PCOS mice

METHODS

Thirty-one female C57BL/6J mice were divided into four groups: two were treated with subcutaneous dehydroepiandrosterone (DHEA) implants and divided into normal and hypercaloric diet (HFD). Two were control and divided into normal and HFD. Presence of insulin resistance, growth, and adipocyte markers expression of white and brown adipose tissues and growth and inflammatory cytokines expression of bone marrow adipose tissue were evaluated.

RESULTS

Hypercaloric diet groups presented higher total weight gain and huge growth in all fat sites, except bone marrow. They also demonstrated greater expression of adipocyte markers in sites of white adipose tissue. DHEA + HFD group showed more insulin intolerance than all other groups. DHEA shows to abrogate AdipoQ expression in all fatty tissues.

CONCLUSIONS

DHEA alone does not influence adipose tissue growth, but contributes to increased insulin resistance and influences the expression of adipokines. Proximal MAT showed different behavior from the other fat depot.

Metformin decreases miR-122, miR-223 and miR-29a in women with polycystic ovary syndrome

Metformin is associated with increased insulin sensitivity, whereas oral contraceptive pills (OCP) could increase the risk for type 2 diabetes (T2D) in women with polycystic ovary syndrome (PCOS). Certain miRNAs might serve as biomarkers for the risk of T2D. The aim of this study was to investigate changes in circulating miRNA levels during treatment with metformin and OCP in women with PCOS. Sixty-five women with PCOS according to Rotterdam criteria were randomized to metformin (2 g/day), metformin + OCP (150 mg desogestrel + 30 µg ethinylestradiol) or OCP alone for 12 months. Serum miRNA analysis was performed with individual RT-qPCR or Taqman low density array cards of 22 selected miRNAs previously related to PCOS, glucose and/or lipid metabolism. miR-122 and miR-29a levels were decreased after treatment with metformin compared with metformin + OCP and OCP group: miR-122: log2 difference -0.7 (P = 0.01) and -0.7 (P = 0.02), miR-29a: log2 difference -0.5 (P = 0.01) and -0.4 (P = 0.04), while miR-223 levels were decreased in the metformin + OCP group after treatment: log2 difference -0.5 (P = 0.02). During the treatment period, a significant weight loss was observed in the metformin group compared with the OCP group. In the OCP group, miRNA levels were unchanged during the treatment period. Levels of circulating miRNAs associated with lipid and glucose metabolism decreased during metformin treatment. Changes in miRNA levels in the metformin group could be explained by the simultaneous weight loss in the same group. These results support the notion that metformin treatment alone may be superior for metabolic health compared with OCP.

Changes in Metabolic Profile in the Women with a History of PCOS-A Long-Term Follow-Up Study

Data concerning metabolic consequences in women with polycystic ovary syndrome (PCOS) are delivered mainly by cross-sectional studies. In this research, we re-examined 31 Caucasian PCOS women after a median period of 120.9 months to evaluate the changes in metabolic syndrome components. Clinical examination, oral glucose tolerance test with estimations of glucose and insulin, lipids, sex hormone-binding globulin (SHBG) and sex hormones assessments were performed on two occasions. Additionally, the euglycaemic hyperinsulinaemic clamp technique was used at the baseline to assess insulin sensitivity (M-clamp value). In the end, the median age of participants was 35. We observed an increase in glucose concentrations, a decrease in insulin concentrations and no changes in insulin resistance markers. Final mean glucose, mean insulin, Matsuda index and body mass index (BMI) were correlated with baseline M-clamp value and SHBG (p < 0.01). During the follow-up, no one in the sample developed diabetes. The annualised incidence rate for conversion from normoglycaemia to prediabetes totalled 4.5%. Baseline BMI, free androgen index, fasting glucose and M-clamp value were identified as prediabetes predictors in young PCOS women (respectively, OR = 1.17, OR = 1.42, OR = 1.2, OR = 0.73, p < 0.05). Prediabetes appeared in 76.47% of the women with a final BMI of ≥ 25 kg/m² and in 7.14% of the normal-weight women (p = 0.0001). In conclusion, we report a high rate of adverse change in glucose metabolism in overweight and obese participants, a deterioration in β-cell function and strong correlations between metabolic parameters assessed in the third and the fourth decade in PCOS women, emphasising the role of early intervention to prevent cardiometabolic diseases.

Genetic construction between polycystic ovarian syndrome and type 2 diabetes

Polycystic ovarian syndrome (PCOS) in reproductive-aged women is identified to be one of the endocrine disorders. This heterogeneous disorder is categorized through oligo-anovulation and hyperandrogenemia. National institutes of health and Rotterdam criterions were used to diagnose PCOS women. Type 2 Diabetes (T2D) is one of the complications in PCOS which is connected through insulin resistance (IR), which is a condition in which liver, muscles and fat infrequently respond to the hormones, and this leads to extreme IR and consequently leads to T2D disease. PCOS is inherited by the autosomal dominant mode of inheritance and may also with the different intricate patterns. Till now, many studies have been performed in PCOS with the genes identified by T2D and till now no studies have shown the similar genetic association and pathophysiology between both the diseases. So, the current review aims to investigate the genetic relation between PCOS and T2D and why both the diseases cannot be reverted. In this review, published data were screened with the T2D related genes and single nucleotide polymorphisms in PCOS women. The case-control, hospital-based and meta-analysis molecular studies disclosed both positive and negative connotations. Genetically, no relationship has been established between PCOS and T2D. Maximum studies have shown as PCOS women had developed T2D later in life because as a risk-factor, but none of the studies documented T2D women having developed PCOS as a risk factor. Apart from this, the disease PCOS is developed in women with reproductive age and T2D develops in both the men and women during adulthood. This review concludes as there is a genetic relation only in between PCOS and T2D, but not with T2D to PCOS and further it cannot be explicitly reverted from T2D to PCOS.

Cardiovascular Risk in Postmenopausal Women with Polycystic Ovary Syndrome

Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies affecting women of reproductive age. The hormonal alterations of PCOS have been linked with a higher risk of metabolic disturbances in young, reproductively active women. However, it remains to be clarified whether the presence of PCOS increases the risk of cardiovascular disease (CVD) later in life. Aging ameliorates the clinical manifestations of PCOS; hyperandrogenaemia and metabolic abnormalities, however, persist beyond the menopause. On the other hand, aging and menopause increase CVD risk in the general female population. The results of the limited available studies in aging women with a previous diagnosis of PCOS demonstrate early atherosclerosis. However, studies addressing clinical CVD outcomes in women with PCOS report inconsistent findings. A possible explanation for this heterogeneity is the difficulty in diagnosing PCOS after the menopausal transition, due to the absence of validated diagnostic criteria for this population. Larger prospective studies of women diagnosed during their reproductive years will shed more light on the longer-term CVD implications of PCOS.
