Abstract
Despite affecting ~11-13% of women globally, polycystic ovary syndrome (PCOS) is a substantially understudied condition. PCOS, possibly extending to men's health, imposes a considerable health and economic burden worldwide. Diagnosis in adults follows the International Evidence-based Guideline for the Assessment and Management of Polycystic Ovary Syndrome, requiring two out of three criteria - clinical or biochemical hyperandrogenism, ovulatory dysfunction, and/or specific ovarian morphological characteristics or elevated anti-Müllerian hormone. However, diagnosing adolescents omits ovarian morphology and anti-Müllerian hormone considerations. PCOS, marked by insulin resistance and hyperandrogenism, strongly contributes to early-onset type 2 diabetes, with increased odds for cardiovascular diseases. Reproduction-related implications include irregular menstrual cycles, anovulatory infertility, heightened risks of pregnancy complications and endometrial cancer. Beyond physiological manifestations, PCOS is associated with anxiety, depression, eating disorders, psychosexual dysfunction and negative body image, collectively contributing to diminished health-related quality of life in patients. Despite its high prevalence persisting into menopause, diagnosing PCOS often involves extended timelines and multiple health-care visits. Treatment remains ad hoc owing to limited understanding of underlying mechanisms, highlighting the need for research delineating the aetiology and pathophysiology of the syndrome. Identifying factors contributing to PCOS will pave the way for personalized medicine approaches. Additionally, exploring novel biomarkers, refining diagnostic criteria and advancing treatment modalities will be crucial in enhancing the precision and efficacy of interventions that will positively impact the lives of patients.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is an endocrinological and metabolic disorder that can lead to female infertility. Lipid metabolomics and proteomics are the new disciplines in systems biology aimed to discover metabolic pathway changes in diseases and diagnosis of biomarkers. This study aims to reveal the features of PCOS to explore its pathogenesis at the protein and metabolic level. METHODS We collected follicular fluid samples and granulosa cells of women with PCOS and normal women who underwent in vitro fertilization(IVF) and embryo transfer were recruited. The samples were for the lipidomic study and the proteomic study based on the latest metabolomics and proteomics research platform. RESULTS Lipid metabolomic analysis revealed abnormal metabolism of glycerides, glycerophospholipids, and sphingomyelin in the FF of PCOS. Differential lipids were strongly linked with the rate of high-quality embryos. In total, 144 differentially expressed proteins were screened in ovarian granulosa cells in women with PCOS compared to controls. Go functional enrichment analysis showed that differential proteins were associated with blood coagulation and lead to follicular development disorders. CONCLUSION The results showed that the differential lipid metabolites and proteins in PCOS were closely related to follicle quality,which can be potential biomarkers for oocyte maturation and ART outcomes.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS), an incidence of 10-15% in women of reproductive age, shows sex hormone disorders, luteal insufficiency, and the tendency of placental villus space thrombus. The incidence of early pregnancy loss in women with PCOS is three to eight times higher than that in non-PCOS women. PCOS women were reported in a pre-thrombotic state, which was manifested by accelerated thrombin production, increased PAI-1 activity, and fibrinogen. Other research also found an over-activated state of women with PCOS in immune system. Therefore, changing the prethrombotic state of PCOS through anticoagulation may be a new way to improve the adverse pregnancy outcome of PCOS. Low-molecular-weight heparin (LMWH) is the most common used anticoagulant drug in pregnancy, and it also was proposed for the prevention of recurrent abortion, although the application of LMWH in PCOS population during early pregnancy has not been reported. The objective of this study is to investigate the effect of LMWH on pregnancy outcomes after invitro fertilization-frozen embryo transfer (IVF-FET) in patients with polycystic ovary syndrome. METHODS A total of 356 PCOS women aged between 20 and 38 years which prepared for IVF followed with FET will be enrolled in the study. The patients, from four different hospitals stratified by age and body mass index (BMI), will be randomly divided into the study group who will be treated with LMWH started on the day of progesterone transformation (hormone therapy) during FET cycle and the control group without additional medicine. Serum or urine hCG test will be given 14 days after embryo transfer to confirm biochemical pregnancy. If pregnancy is positive, LMWH+ hormone therapy/hormone therapy will be continued for another 2 weeks. Transvaginal ultrasonography will be performed 14 days later to confirm intrauterine pregnancy. The primary outcome is the ongoing pregnancy, which is defined as intrauterine live fetus with ultrasound after 12 weeks of gestation. DISCUSSION This is the first study protocol to investigate the efficacy of LMWH as an adjuvant drug for IVF-FET outcomes in PCOS women, by comparing differences in ongoing pregnancy rate, clinical pregnancy rate, live birth rate, and early pregnancy loss rate between LMWH group and the control group.

Abstract
Incidents of strokes are increased in young women relative to young men, suggesting that oral contraceptive (OC) use is one of the causes of stroke among young women. Long-term exposures to the varying combinations of estrogen and progestogen found in OCs affect blood clotting, lipid and lipoprotein metabolism, endothelial function, and de novo synthesis of neurosteroids, especially brain-derived 17β-estradiol. The latter is essential for neuroprotection, memory, sexual differentiation, synaptic transmission, and behavior. Deleterious effects of OCs may be exacerbated due to comorbidities like polycystic ovary syndrome, sickle cell anemia, COVID-19, exposures to endocrine disrupting chemicals, and conventional or electronic cigarette smoking. The goal of the current review is to revisit the available literature regarding the impact of OC use on stroke, to explain possible underlying mechanisms, and to identify gaps in our understanding to promote future research to reduce and cure stroke in OC users.

Abstract
Thrombocytosis can be either primary or secondary, and it can cause venous pro-thrombotic states like cerebral venous thrombosis. Untreated iron deficiency anemia is postulated to cause reactive (secondary) thrombocytosis due to the proliferation of common progenitor cells. Here we present a case of a middle-aged woman with polycystic ovary syndrome and episodes of menorrhagia. She presented with headache and focal sensory deficits, and her neuroimaging showed evidence of cerebral venous sinus thrombosis (CVST). Laboratory tests showed microcytic hypochromic anemia, low ferritin, high total iron-binding capacity (TIBC), and thrombocytosis with a platelet count of 1,523,000/mm³. A comprehensive workup for hypercoagulable states and primary causes of thrombocytosis was negative. It was concluded that the etiology of her CVST was a reactive thrombocytosis from chronic untreated iron deficiency anemia. Anticoagulation with apixaban and corrective treatment for iron deficiency anemia was initiated. A repeated neuroimaging after four months showed significantly less clot burden in the cerebral venous sinuses, and then apixaban was stopped after six months. Laboratory tests after one year of iron replacement therapy showed improvement in the hemoglobin and hematocrit as well as normalization of platelet count. This case highlights a rare yet potentially dangerous complication of a common untreated condition, i.e., iron deficiency anemia.

Abstract
BACKGROUND The aim of this study was to apply proteomic methodology for the analysis of proteome changes in women with polycystic ovary syndrome (PCOS). MATERIAL AND METHODS All the participators including 31 PCOS patients and 31 healthy female as controls were recruited, the clinical characteristics data was recorded at the time of recruitment, the laboratory biochemical data was detected. Then, a data-independent acquisition (DIA)-based proteomics method was performed to compare the serum protein changes between PCOS patients and controls. In addition, Western blotting was used to validate the expression of identified proteomic biomarkers. RESULTS There were 80 proteins differentially expressed between PCOS patients and controls significantly, including 54 downregulated and 26 upregulated proteins. Gene ontology and Kyoto Encyclopedia of Genes and Genomes analysis showed that downregulated proteins were enriched in platelet degranulation, cell adhesion, cell activation, blood coagulation, hemostasis, defense response and inflammatory response terms; upregulated proteins were enriched in cofactor catabolic process, hydrogen peroxide catabolic process, antioxidant activity, cellular oxidant detoxification, cellular detoxification, antibiotic catabolic process and hydrogen peroxide metabolic process. Receiver operating characteristic curves analysis showed that the area under curve of Histone H4 (H4), Histone H2A (H2A), Trem-like transcript 1 protein (TLT-1) were all over than 0.9, indicated promising diagnosis values of these proteins. Western blotting results proved that the detected significant proteins, including H4, H2A, TLT-1, Peroxiredoxin-1, Band 3 anion transport protein were all differently expressed in PCOS and control groups significantly. CONCLUSION These proteomic biomarkers provided the potentiality to help us understand PCOS better, but future studies comparing systemic expression and exact role of these candidate biomarkers in PCOS are essential for confirmation of this hypothesis.

Abstract
Polycystic ovary syndrome (PCOS) is a common endocrine disorder in reproductive-aged women, characterized by hyperandrogenism, oligo/anovulation, and polycystic ovarian morphology. Combined oral contraceptives (COCs), along with lifestyle modifications, represent the first-line medical treatment for the long-term management of PCOS. Containing low doses of estrogen and different types of progestin, COCs restore menstrual cyclicity, improve hyperandrogenism, and provide additional benefits such as reducing the risk of endometrial cancer. However, potential cardiometabolic risk associated with these agents has been a concern. COCs increase the risk of venous thromboembolism (VTE), related both to the dose of estrogen and the type of progestin involved. Arterial thrombotic events related to COC use occur much less frequently, and usually not a concern for young patients. All patients diagnosed with PCOS should be carefully evaluated for cardiometabolic risk factors at baseline, before initiating a COC. Age, smoking, obesity, glucose intolerance or diabetes, hypertension, dyslipidemia, thrombophilia, and family history of VTE should be recorded. Patients should be re-assessed at consecutive visits, more closely if any baseline cardiometabolic risk factor is present. Individual risk assessment is the key in order to avoid unfavorable outcomes related to COC use in women with PCOS.

Abstract
Although the current literature associates polycystic ovarian syndrome (PCOS) with chronic inflammation, the evidence for this link remains inconclusive and its causal nature remains unclear. The purpose of this systematic review was to assess the inflammatory status in PCOS women and to determine whether it is related to PCOS or to its associated adiposity. We searched electronic databases including PUBMED, EMBASE and MEDLINE, SCOPUS, DynaMed plus, TRIP, ScienceDirect and Cochrane Library, for studies investigating C-reactive protein (CRP) and other inflammatory makers in PCOS women versus healthy controls. Quality and risk of bias for selected studies were assessed using the modified Newcastle-Ottawa scale. CRP data were extracted and pooled using RevMan for calculation of the standardized mean difference (SMD) and 95% confidence interval (CI). Eighty-five eligible studies were included in the systematic review, of which 63 were included in the meta-analysis. Pooled analysis of the 63 studies revealed significantly higher circulating CRP in PCOS women (n = 4086) versus controls (n = 3120) (SMD 1.26, 95%CI, 0.99, 1.53). Sensitivity meta-analysis of 35 high quality studies including non-obese women showed significantly higher circulating CRP in PCOS women versus controls (SMD 1.80, 95%CI, 1.36, 2.25). In conclusion, circulating CRP is moderately elevated in PCOS women independent of obesity, which is indicative of low-grade chronic inflammation.

Abstract
Background and Aim We aimed to compare the levels of clinical, biochemical, hormonal, and metabolic parameters as well as serum CRP, fibrinogen, leptin, and adiponectin in cases with PCOS and control group to investigate whether they play a role in the etiology of the syndrome. Materials and Methods The present study included a total of 90 subjects, 45 subjects were diagnosed with PCOS (n = 45) and 45 subjects served as control group (n = 45). Serum CRP, fibrinogen, leptin, and adiponectin levels were analyzed for each subject. Results Serum CRP, fibrinogen, and leptin were found to be higher (statistically significant) in the group with PCOS as compared to the control group (p < 0.05). Serum Adiponectin was higher in the control group (statistically significantly) as compared with the patients in the PCOS group (p < 0.05). Conclusion CRP and fibrinogen (cardiac risk factor markers) increase in women with PCOS. The levels of leptin which affects metabolism increase, whereas the levels of adiponectin decrease.

Abstract
Endogenous and exogenous hormones have significant effects on coagulation and may tip the hemostatic balance toward thrombosis. The endogenous hormonal changes in pregnancy and polycystic ovary syndrome, and exogenous hormonal contraception, menopause replacement, and transgender cross-hormone replacement may increase thromboembolism risk. Using the lowest effective dose is critical for prevention, but once thrombosis occurs, anticoagulation may be required, in some, long term. We review the relative risk of thrombosis in these conditions, risk factors, and anticoagulation treatment and prevention. Implementation of lowest effective hormonal therapies, thrombosis reduction strategies, and current anticoagulation management are critical for optimal patient outcomes.

The spread of a new coronavirus infection worldwide since the end of 2019 has becomes a pandemic. Thrombotic complications are the leading cause of death in this disease. After entering the human body, the virus starts a cascade of reactions leading to the development of a cytokine storm, activation of all parts of the hemostasis and complement systems and other changes that result in disturbances in the circulation system with the development of multiple organ failures. Numerous studies have shown that a predictor of a severe course of COVID-19 is a sharp increase of D-dimer concentration in the blood and rise of some other markers of hemostasis activation. Based on the pathogenesis, the developed schemes for the prevention and treatment of COVID-19 severe complications include low molecular weight heparins (LMWH) which are also recommended for an outpatient COVID-19 patient. The prescription of low molecular weight heparin, the duration of their use and doses should be decided on the basis of a risk assessment of factors for each individual patient in combination with laboratory monitoring.

Abstract
More than 1 out of 10 women worldwide are diagnosed with polycystic ovary syndrome (PCOS), the leading cause of female reproductive and metabolic dysfunction. Despite its high prevalence, PCOS and its accompanying morbidities are likely underdiagnosed, averaging > 2 years and 3 physicians before women are diagnosed. Although it has been intensively researched, the underlying cause(s) of PCOS have yet to be defined. In order to understand PCOS pathophysiology, its developmental origins, and how to predict and prevent PCOS onset, there is an urgent need for safe and effective markers and treatments. In this review, we detail which animal models are more suitable for contributing to our understanding of the etiology and pathophysiology of PCOS. We summarize and highlight advantages and limitations of hormonal or genetic manipulation of animal models, as well as of naturally occurring PCOS-like females.

Abstract
AIMS Polycystic ovary syndrome (PCOS) is very prevalent and commonly treated with prothrombotic combined oral contraceptives (COC). Our aim was to systematically review the available evidence to evaluate the risk of venous thromboembolism (VTE) associated with PCOS, and whether observed increased risks may be explained by a higher prevalence of obesity and hormonal treatments. METHOD For this systematic review and meta-analysis, two authors independently searched MEDLINE, EMBASE and conference proceedings (ISTH, WHITH) from inception through 4.2019 for studies reporting the association of PCOS with VTE risk. Study quality was assessed and relative risk estimates were pooled through random effect models. RESULTS We identified 5 large observational studies published between 2004 and 2018, most commonly using administrative data, set in Denmark, the USA or the United Kingdom. Compared with participants without PCOS, participants with PCOS had greater risks of VTE in unadjusted analyses (pooled OR 1.70, 95%CI 1.42-2.04, I2 67%). In three studies reporting analyses adjusted for at least obesity and hormonal treatments, PCOS was still associated with greater risks of VTE (pooled OR 1.89, 95%CI 1.60-2.24, I2 27%). CONCLUSIONS PCOS appears to be a risk factor for VTE, independently of its associated excess weight and greater use of combined oral contraceptives. This should be taken into account in the pharmacological management of PCOS.

Abstract
Background & objectives: Polycystic ovary syndrome (PCOS) is an endocrinopathy warranting lifelong individualized management by lifestyle and pharmacological agents mainly oral contraceptive pills (OCPs). This study was aimed to report the impact of six-month OCP use on plasminogen activator inhibitor-1 (PAI-1) and factor VIII (FVIII) in women with PCOS. Methods: PCOS women diagnosed on the basis of Rotterdam 2003 criteria, either treated with OCPs (ethinyl estradiol-0.03 mg, levonorgestrel-0.15 mg) for a period of six months (n=40) or drug-naïve (n=42), were enrolled in this study. Blood was drawn to estimate glucose, insulin levels and lipid profile. Chemiluminescence immunoassays were used to measure hormones (LH, FSH, PRL, T4). Plasma levels of PAI-I and FVIII were measured by commercially available kits. Results: Menstrual regularity, Ferriman-Gallwey score and serum total testosterone significantly improved in the OCP group compared to drug-naïve group (P<0.01). No significant difference was observed in PAI-1 levels of the two groups; however, significant decrease in FVIII levels was observed in OCP group as compared to drug-naïve group. PAI-1 levels of OCP group correlated positively with blood glucose two hours, triglycerides and insulin two hours, while FVIII levels of OCP group correlated negatively with fasting insulin and homoeostatic model assessment-insulin resistance. Interpretation & conclusions: OCPs use has differential effect on pro-coagulant markers among women with PCOS. Well-designed, long-term, prospective, large-scale studies are prerequisite to elucidate the efficacy and safety of OCP in the treatment of PCOS.

Abstract
Introduction Pregnant women with polycystic ovarian syndrome (PCOS) have high risk of pregnancy loss. Pathophysiological mechanisms appear to be associated with obesity, hormonal factors, or blood clotting disorders. Our aim is to perform a systematic review and meta-analysis on the relationship between coagulation disorders and risk of recurrent miscarriage (RM) in patients with PCOS and to identify coagulation biomarkers for this condition. Material and Methods PubMed and MEDLINE databases were searched for publications in English language. The search terms used included "RM", "polycystic ovary syndrome", "coagulation disorders", and "thrombophilia". Odds ratios (ORs) and 95% confidence intervals (CIs) for miscarriage in different RM groups (with and without PCOS). Results A total of 575 publications including the search terms were identified. Six studies were included for qualitative analysis, and five were included for quantitative analysis (meta-analysis). We found no association between RM and inherited thrombophilias in patients with PCOS: (1) Factor V Leiden (OR, 0.74; 95% CI, 0.38 - 1.45; p = 0.38); (2) C677T methylenetetrahydrofolate reductase polymorphism (MTHFR) (OR, 1.01; 95% CI, 0.64 - 1.59; p = 0.97); and (3) A1297C MTHFR polymorphism (OR, 1.08; 95% CI, 0.62 - 1.89; p = 0.77). Other potential biomarkers were identified, with emphasis on plasminogen activator inhibitor type 1. Conclusion Data available in the current literature revealed that there was no association between RM and inherited thrombophilias in patients with PCOS. RM patients with PCOS have a high risk of thromboembolic events.

Abstract
RESEARCH QUESTION Polycystic ovary syndrome (PCOS) women have increased cardiovascular risks, although it is unclear whether the haemostatic system and coagulation contribute to that increased risk. DESIGN Women attending the Gynecology Unit of the 'Virgen de la Arrixaca' University Hospital (Murcia, Spain) for routine gynaecological examinations between September 2014 and May 2016 were assessed for PCOS using the Rotterdam criteria (hyperandrogenism [H], oligo/amenorrhoea [O] and polycystic ovarian morphology [POM]) and were classified into four phenotypic. In total, 126 cases were identified and 159 control women were selected. All women underwent physical and gynaecological examinations, and blood tests between the second and fifth day of the menstrual cycle. Differences in hormonal, basal thrombophilia and metabolic parameters, and C-reactive protein (CRP) between PCOS and controls were analysed. RESULTS After adjusting by BMI and age, PCOS women had higher LH (P < 0.001), testosterone (P < 0.001), free testosterone (P = 0.01) and anti-Müllerian hormone (P < 0.001) and lower FSH (P = 0.03) compared with controls, whereas sex hormone-binding globulin was no different. Cases showed significantly higher protein S, glucose, insulin and insulin resistance (HOMA-IR) compared with controls (P < 0.05). There were no differences in protein C levels, antithrombin III, prothrombin time, homocysteine, D-dimer, factor V Leyden, prothrombin G20210A polymorphism or CRP. The H+O phenotype showed the poorest results for insulin and HOMA-IR (P = 0.04 and 0.05). CONCLUSIONS The results suggest that there are no differences in the basal thrombophilias between women with and without PCOS. However, PCOS with H+O shows the poorest metabolic profile.

Abstract
Background: Polycystic ovary syndrome (PCOS) is associated with an adverse cardiovascular risk profile including a prothrombotic state. Exenatide has been shown to be effective at improving insulin sensitivity and weight loss in PCOS; therefore this study was undertaken to assess its effects on weight, endothelial function, inflammatory markers, and fibrin structure/function in overweight/obese women with PCOS. Methods: Thirty overweight/obese anovulatory women with all 3 Rotterdam criteria received exenatide 5 mcg bd for 4 weeks then 10 mcg bd for 12 weeks. The primary outcome was change in weight; secondary outcomes were changes in endothelial function [Reactive Hyperemia-Peripheral Arterial Tonometry (RH-PAT)], serum endothelial markers (ICAM-1, VCAM-1, E-selectin, and P-selectin), change in inflammation (hsCRP), and alteration in clot structure and function [maximum absorbance (MA), and time from full clot formation to 50% lysis (LT)]. Results: Twenty patients completed the study. Exenatide reduced weight 111.8 ± 4.8 to 108.6 ± 4.6 kg p = 0.003. Serum endothelial markers changed with a reduction in ICAM-1 (247.2 ± 12.9 to 231.3 ± 11.5 ng/ml p = 0.02), p-selectin (101.1 ± 8.2 to 87.4 ± 6.6 ng/ml p = 0.01), and e-selectin (38.5 ± 3.3 to 33.6 ± 2.6 ng/ml p = 0.03), without an overt change in endothelial function. Inflammation improved (CRP; 8.5 ± 1.4 to 5.6 ± 0.8 mmol/L p = 0.001), there was a reduction in clot function (LT; 2,987 ± 494 to 1,926 ± 321 s p = 0.02) but not clot structure. Conclusion: Exenatide caused a 3% reduction in weight, improved serum markers of endothelial function, inflammation, and clot function reflecting an improvement in cardiovascular risk indices in these women with PCOS. This suggests exenatide could be an effective treatment for obese women with PCOS. Clinical Trial Registration: ISRCTN81902209.

Abstract
Background The aim of the study was to evaluate high-sensitivity C-reactive protein (hs-CRP) and fibrinogen in non-obese normoinsulinemic adolescent girls with polycystic ovary syndrome (PCOS) and their relationship with anthropometric and lipid parameters. Methods The study comprised a total of 26 adolescent girls newly diagnosed with PCOS and 12 healthy controls with regular ovulatory menstrual cycles. The concentration of hs-CRP, fibrinogen, anthropometric measurements, and biochemical and hormonal testing were assessed. Results PCOS adolescent girls had significantly higher levels of hs-CRP and fibrinogen compared to healthy controls. In univariate regression analysis, statistically significant associations of hs-CRP and fibrinogen levels of PCOS patients have been shown with body mass index (BMI), waist circumference (WC), hip circumference (HC) and low-density lipoprotein (LDL)/high-density lipoprotein (HDL) ratio, while hs-CRP levels were also associated with cholesterol and LDL. In the multivariate regression model, we found that hs-CRP levels were predicted by BMI (β=0.541, p<0.001) and LDL (β=0.507, p=0.014), while fibrinogen levels were predicted by BMI (β=0.449, p=0.004). Conclusions We have shown an association of proinflammatory indices hs-CRP and fibrinogen with anthropometric and lipid parameters of adolescent women with PCOS. The inflammatory markers might be useful in monitoring normal-weight adolescent women with PCOS in an effort to timely prevent unfavorable changes in body mass and lipid profile.

Abstract
Abstract
Polycystic Ovary Syndrome (PCOS) is characterized by hyperandrogenism, amenorrhea, and polycystic ovaries. This endocrinopathy is associated with many metabolic disorders such as dyslipidemia and insulin resistance, with increased risk of type 2 diabetes mellitus, metabolic syndrome, and cardiovascular complications. Inflammation is likely to play an important role in the promoting these metabolic imbalances, while prothrombotic and pro-oxidative mechanisms further contribute to the cardiovascular risk of these patients. The etiology of PCOS is still not fully understood, but there is evidence of genetic and environmental components. This review aims to discuss some molecular pathways associated with PCOS that could contribute to the better understanding about this syndrome. Recent evidence suggests that intrauterine exposure of female mice to an excess of anti-Müllerian hormone may induce PCOS features in their post-natal life. High cytokine levels and cytokine gene polymorphisms also appear to be associated with the pathophysiology of PCOS. Furthermore, high levels of microparticles may contribute to the altered hemostasis and enhanced inflammation in PCOS. All these mechanisms may be relevant to clarify some aspects of PCOS pathogenesis and inspire new strategies to prevent the syndrome as well as treat its symptoms and mitigate the risk of long-term complications.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women during their reproductive ages, associated with a plethora of cardiometabolic consequences, with obesity, insulin resistance and hyperandrogenemia playing a major role in the degree of such manifestations. These consequences include increased risk of glucose intolerance and diabetes mellitus (both type 2 and gestational), atherogenic dyslipidemia, systemic inflammation, non-alcoholic fatty liver disease, hypertension and coagulation disorders. Whether this cluster of metabolic abnormalities is also translated in increased cardiovascular disease (CVD) morbidity and mortality in later life, remains to be established. Data so far based on markers of subclinical atherosclerosis as well as retrospective and prospective cohort studies indicate a possible increased CVD risk, mainly for coronary heart disease. Future studies are needed to further elucidate this issue.

[PMID: 29293982 DOI: 10.1093/humupd/dmx039] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2017] [Revised: 11/30/2017] [Accepted: 12/06/2017] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND Androgen excess is a key pathogenetic mechanism in polycystic ovary syndrome (PCOS), although hyperinsulinism also contributes to androgen secretion. Therapeutic approaches for adult patients not seeking fertility include combined oral contraceptives (COC), antiandrogens (AA) and/or insulin sensitizers, although these practices are supported by limited high-quality evidence. OBJECTIVE AND RATIONALE We aimed to assess the efficacy and safety of these common treatments for PCOS by conducting a meta-analysis of RCTs with the following review questions: Which is the more appropriate therapeutic approach for hyperandrogenic symptoms, hyperandrogenemia, and ovulatory dysfunction in adult women with PCOS not seeking fertility; What is the impact on classic cardiometabolic risk factors of the more common treatments used in those women; Does the combination of the antiandrogenic therapy plus metformin have any impact on efficacy or cardiometabolic profile? SEARCH METHODS We searched PubMed and EMBASE for articles published up to 16 September 2017. After deleting duplicates, the abstracts of 1522 articles were analysed. We subsequently excluded 1446 articles leaving 76 studies for full-text assessment of eligibility. Of them, 43 articles were excluded. Hence, 33 studies and 1521 women were included in the quantitative synthesis and in the meta-analyses. Meta-analyses calculated mean differences (MD), standardized mean differences (SMD), odds ratio (OR) and 95% CIs. Heterogeneity and inconsistency across studies was assessed by χ2 test and Higgins's I2 statistics. Quality and risk of bias of individual studies were assessed according to the Cochrane Handbook for Systematic Reviews of Interventions 5.1.0. We then used the approach recommended by the Grading of Recommendations, Assessments, Development, and Evaluation (GRADE) group to indicate the global quality of evidence for a selection of primary outcomes. OUTCOMES Regarding efficacy, the MD in hirsutism score between COC and/or AA and metformin were not significant. The exclusion of one single study including most women with severe hirsutism yielded a significant effect in favour of COC and/or AA. When only those studies including an AA were compared with metformin, there were significant differences favouring antiandrogenic therapy. The combination of COC and/or AA with metformin was similar to COC and/or AA therapy alone in the whole group of patients. Post-intervention OR for the presence of regular menses favoured COC therapy. In terms of cardiometabolic impact, the MD in BMI were in favour of metformin. The negative effect of COC therapy on BMI was blunted by its combination with metformin. The MD in homoeostasis model assessment of insulin resistance (HOMA-IR) were also in favour of metformin therapy compared to COC and/or AA. The combination of COC and/or AA and metformin decreased MD in HOMA with respect to antiandrogenic therapy alone. There were no significant post-intervention SMD in circulating glucose levels between COC and/or AA and metformin. However, adding metformin to COC and/or AA yielded a beneficial effect on fasting glucose levels. Post-intervention OR for abnormal glucose tolerance showed no significant differences between COC and/or AA and metformin, although after excluding studies including an AA as a comparator (without COC) a significant effect in favour of metformin therapy was observed. There were no significant differences among therapies in lipid profile, blood pressure or prevalence of hypertension. The global quality of evidence was very low when addressing the impact of the treatments explored on prevalence of hypertension and lipid profiles, low in the case of hirsutism, BMI and blood pressure values, and high for endometrial protection and glucose tolerance. WIDER IMPLICATIONS These data provide further scientific evidence for the choice of treatment of women with PCOS. COC and AA are more effective than metformin for hyperandrogenic symptoms and endometrial protection. Their combination with metformin adds a positive effect on BMI and glucose tolerance.

Abstract
Classic features of polycystic ovary syndrome (PCOS) include derangement of metabolic and cardiovascular health, and vascular dysfunction is commonly reported. These comorbidities indicate impaired blood flow; however, other than limited reports of increased plasma viscosity, surprisingly little is known regarding the physical properties of blood in PCOS. We aimed to investigate whether haemorheology was impaired in women with PCOS. We thus measured a comprehensive haemorheological profile, in a case-control design, of lean women with PCOS and age-matched healthy controls. A clinical examination determined similar cardiovascular risk for the two groups. Whole blood and plasma viscosity was measured using a cone-plate viscometer. The magnitude and rate of red blood cell (RBC) aggregation was determined using a light-transmission aggregometer, and the degree of RBC deformability was measured via laser-diffraction ektacytometry. Plasma viscosity was significantly increased in women with PCOS. Blood viscosity was also increased for PCOS at lower-to-moderate shear rates in both native and standardised haematocrit samples. The magnitude of RBC aggregation–a primary determinant of low-shear blood viscosity–was significantly increased in PCOS at native and 0.4 L·L-1 haematocrit. No difference was detected between PCOS and CON groups for RBC deformability measurements. A novel measure indicating the effectiveness of oxygen transport by RBC (i.e., the haematocrit-to-viscosity ratio; HVR) was decreased at all shear rates in women with PCOS. In a group of young and lean women with PCOS with an unremarkable cardiovascular risk profile based on clinical data, significant haemorheological impairment was observed. The degree of haemorheological derangement observed in the present study reflects that of overt chronic disease, and provides an avenue for future therapeutic intervention in PCOS.

Abstract
Genetic and epigenetic factors may predispose women to polycystic ovary syndrome (PCOS), a common heritable disorder of unclear etiology. Here we investigated differences in genome-wide gene expression and DNA methylation in adipose tissue from 64 women with PCOS and 30 controls. In total, 1720 unique genes were differentially expressed (Q < 0.05). Six out of twenty selected genes with largest expression difference (CYP1B1, GPT), genes linked to PCOS (RAB5B) or type 2 diabetes (PPARG, SVEP1), and methylation (DMAP1) were replicated in a separate case-control study. In total, 63,213 sites (P < 0.05) and 440 sites (Q < 0.15) were differently methylated. Thirty differentially expressed genes had corresponding changes in 33 different DNA methylation sites. Moreover, a total number of 1913 pairs of differentially expressed “gene-CpG” probes were significantly correlated after correction for multiple testing and corresponded with 349 unique genes. In conclusion, we identified a large number of genes and pathways that are affected in adipose tissue from women with PCOS. We also identified specific DNA methylation pathways that may affect mRNA expression. Together, these novel findings show that women with PCOS have multiple transcriptional and epigenetic changes in adipose tissue that are relevant for development of the disease.

Abstract
BACKGROUND Women with type 2 diabetes mellitus (T2DM) have a higher risk of fractures despite increased bone mineral density (BMD). In experimental studies a potential role of plasminogen activator inhibitor-1 (PAI-1) in bone remodeling is suggested but studies in humans are lacking. This is a first study in humans investigating whether circulated levels of PAI-1 in postmenopausal women with T2DM are related to BMD and adiposity. METHODS Anthropometric variables, PAI-1 and insulin levels, serum lipids and bone turnover markers were measured in 127 postmenopausal women with T2DM. A total of 117 female patients were divided according to lumbar spine BMD measurements via dual-energy x-ray absorptiometry in three groups: 47 with osteopenia, 21 with osteoporosis and 49 with normal BMD. RESULTS Diabetic patients with normal BMD had significantly higher BMI, greater waist circumference and lower bone turnover markers than diabetics with osteopenia and osteoporosis. PAI-1 was lower in diabetics with osteoporosis and osteopenia compared with diabetics with normal BMD. Multiple regression analysis revealed insulin, triglycerides levels, pyrilinks and beta blocker therapy to be the strongest predictors of PAI-1 levels. PAI-1 levels correlated with both L-BMD and hip BMD, but after adjustment for age and BMI association was no longer significant. CONCLUSION Our findings suggest that elevated PAI-1 levels are associated with higher BMD in obese diabetic patients but the possible implications of this finding and underlying mechanisms still remain unclear. Obviously, metabolic parameters, may affect both BMD and PAI-levels, and association of PAI-1 and BMD could be indirect. However, as pyrilinks is also independently and significantly negatively correlated to PAI-1 its direct involvement in bone metabolism is also plausible. Further investigations are needed to elucidate the nature of interaction of this matrix modulator in relation to energy and bone metabolism in humans.

Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is associated with obesity and insulin resistance. The objective of this cross-sectional study was to investigate the impact of insulin resistance and body mass index (BMI) on inflammatory and hemostatic variables associated with long-term risk of cardiovascular disease in women with PCOS. MATERIAL AND METHODS 149 premenopausal women with PCOS were recruited consecutively from April 2010 to February 2012 at three Danish University Hospitals. The study was conducted at the Department of Gynecology and Obstetrics, Herlev University Hospital, Denmark. PCOS was diagnosed in accordance with the Rotterdam criteria and the women were classified into four phenotypes according to BMI and insulin resistance measured by the homeostasis model assessment of insulin resistance index. Body composition was determined by dual-energy X-ray absorptiometry. Main outcome measures were the biomarkers C-reactive protein (CRP), plasminogen activator inhibitor-1 (PAI-1), and von Willebrand factor antigen. RESULTS Normal weight insulin-resistant PCOS women were characterized by abdominal obesity and elevated levels of plasma PAI-1. Overweight/obese insulin-resistant PCOS women had increased levels of both PAI-1 and CRP. Of the three Rotterdam criteria, only hyperandrogenemia was significantly associated with the hemostatic risk marker of long-term cardiovascular disease risk. CONCLUSIONS Surrogate risk markers for cardiovascular disease are elevated in women with PCOS, especially insulin-resistant and overweight/obese women.

Abstract
Polycystic ovarian syndrome (PCOS) is a complex endocrine condition which is associated with metabolic and cardiovascular complications. It is elevated to a metabolic disorder with significant long term health ramification due to the high prevalence of insulin resistance (IR), impaired glucose tolerance, type 2 diabetes (T2D), dyslipidemia and numerous cardiovascular risk factors in PCOS women. This article concentrates on the recent developments in the regulation of oxidative stress (OS) in PCOS and on the association between PCOS and CVD outcomes. The prognostic events that define the severity of PCOS and involvement of cardiovascular risk in PCOS include endothelial dysfunction (ED) and impaired cardiac structure. Fact is that, in PCOS women, the circulating biomarkers of OS are in abnormal levels that are independent of overweight, which depicts the participation of OS in the pathophysiology of this common derangement. In addition, hyperglycemia (HG) per se, promotes reactive oxygen species (ROS) generation in PCOS. When the destructive ROS outbalances the concentration of physiological antioxidants, OS occurs. The resultant OS, directly stimulates hyperandrogenism and causes extensive cellular injury, DNA damage and/or cell apoptosis. To further the burden, the total serum antioxidant level in PCOS women is compromised, which diminishes the body's defense against an oxidative milieu. Thus, it is evident that OS regulates several cellular mechanisms in PCOS. Improving our understanding about the regulation of OS, critical role of ROS and protein biomarkers in PCOS should lead to novel therapeutic strategies in addressing PCOS-induced CVD. Besides, it is possible that the beneficial effects of dietary or therapeutic antioxidants have significant clinical relevance in PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is associated with decreased fertility, insulin resistance and an increased risk of developing cardiovascular disease. Treating PCOS patients with metformin improves fertility and decreases cardiovascular complications. Given that platelet activation contributes to both infertility and cardiovascular disease development, we assessed platelet reactivity in PCOS patients and the consequences of metformin treatment. Compared to washed platelets from healthy donors, platelets from PCOS patients demonstrated enhanced reactivity and impaired activation of the AMP-activated kinase (AMPK). PCOS platelets also demonstrated enhanced expression of mitochondrial proteins such as the cytochrome c reductase, ATP synthase and the voltage-dependent anion channel-1. However, mitochondrial function was impaired as demonstrated by a decreased respiration rate. In parallel, the phosphorylation of dynamin-related protein-1 (Drp-1) on Ser616 was increased while that on Ser637 decreased. The latter changes were accompanied by decreased mitochondrial size. In insulin-resistant PCOS patients (HOMA-IR> 2) metformin treatment (1.7 g per day for 4 weeks to 6 months) improved insulin sensitivity, restored mitochondrial integrity and function and normalised platelet aggregation. Treatment was without effect in PCOS patients with HOMA-IR< 2. Moreover, treatment of megakaryocytes with metformin enhanced mitochondrial content and in the same cells metformin enhanced the phosphorylation of the Drp-1 on Ser637 via an AMPKα1-dependent mechanism. In conclusion, the improvement of mitochondrial integrity and platelet reactivity may contribute to the beneficial effects of metformin on cardiovascular disease.

Abstract
Background Given the relationship of vitamin D deficiency with insulin resistance syndrome as the component of polycystic ovary syndrome (PCOS), the main aim of this
study was to compare serum level of 25hydroxyvitamin D [25(OH)D] between PCOS
patients and normal individuals. Materials and Methods A cross sectional study was conducted to compare 25(OH)D
level between117 normal and 125 untreated PCOS cases at our clinic in Arash Hospital, Tehran, Iran, during 2011-2012. The obtained levels of 25(OH)D were classified as
follows: lower than 25 nmol/ml as severe deficiency, between 25-49.9 nmol/ml as deficiency, 50-74.9 nmol/ml as insufficiency, and above 75 nmol/ml asnormal. In addition,
endocrine and metabolic variables were evaluated. Results Among PCOS patients, our findings shows 3(2.4%) normal, 7(5.6%) with
insufficiency, 33(26.4%) with deficiency and 82(65.6%) with severe deficiency, whereas in normal participants, 5(4.3%) normal, 4(3.4%) with insufficiency,
28(23.9%) with deficiency and 80(68.4%) with severe deficiency. Comparison of
25(OH)D level between two main groups showed no significant differences (p=
0.65). Also, the calcium and 25(OH)D levels had no significant differences in patients with overweight (p=0.22) and insulin resistance (p=0.64). But we also found
a relationship between 25(OH)D level and metabolic syndrome (p=0.01). Furthermore, there was a correlation between 25(OH)D and body mass index (BMI) in
control group (p=0.01), while the C-reactive protein (CRP) level was predominantly
higher in PCOS group (p<0.001). Conclusion Although the difference of 25(OH)D level between PCOS and healthy women is not significant, the high prevalence of 25(OH)D deficiency is a real alarm for public
health care system and may influence our results.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder amongst women of reproductive age. Although PCOS is diagnosed exclusively based on reproductive criteria, it is also a metabolic disorder. Insulin resistance, impaired glucose tolerance, type 2 diabetes mellitus, obesity, and dyslipidemia are more common in women with PCOS than in age-comparable women without PCOS. Many of the metabolic abnormalities that manifest in PCOS are worsened by the concurrent incidence of obesity. However, some of these metabolic perturbations occur even in lean women with PCOS and therefore are rightfully recognized as intrinsic to PCOS. The intrinsic factors that produce these metabolic disturbances are reviewed in this paper. The consequences of obesity and the other metabolic aberrations are also discussed. The metabolic perturbations in PCOS patients lead to chronic low-grade inflammation and to cardiovascular impairments that heighten the risk of having cardiovascular disease. Even though many studies have shown an elevation in surrogate biomarkers of cardiovascular disease in PCOS women, it is still not clear to what extent and magnitude the elevation precipitates more frequent and earlier events.

Abstract
Adipose tissue dysfunction may be a central factor in the pathogenesis of insulin resistance in women with polycystic ovary syndrome (PCOS). Gene expression in subcutaneous adipose tissue in PCOS and its relation to metabolic and endocrine features of the syndrome have been fragmentarily investigated. The aim was to assess in subcutaneous adipose tissue the expression of genes potentially associated with adipose tissue dysfunction and to explore their relation to features of the syndrome. Twenty-one women with PCOS (body mass index [BMI] 18.2–33.4 kg/m2) and 21 controls (BMI 19.2–31.7 kg/m2) were matched pair-wise for age, body weight, and BMI. Tissue biopsies were obtained to measure mRNA expression of 44 genes (TaqMan Low Density Array). Differential expression levels were correlated with BMI, glucose infusion rate (GIR), sex hormone binding globulin (SHBG), and sex steroids. In PCOS, expression of adiponectin receptor 2 (ADIPOR2), LPL, and twist-related protein 1 (TWIST1) was decreased, while expression of chemokine (C-C motif) ligand 2 (CCL2) and heme oxygenase (decycling 1) (HMOX1) was increased. TWIST1 and HMOX1, both novel adipokines, correlated with BMI and GIR. After BMI adjustment, LPL and ADIPOR2 expression correlated with plasma estradiol, and CCL2 expression correlated with GIR, in all women. We conclude that adipose tissue mRNA expression differed in PCOS women and controls and that two novel adipokines, TWIST1 and HMOX1, together with adiponectin, LPL, and CCL2, and their downstream pathways merit further investigation.

Abstract
BACKGROUND Women with polycystic ovary syndrome (PCOS) have an adverse cardiovascular risk profile and an increased prevalence of nonalcoholic fatty liver disease (NAFLD), which is also associated with an adverse cardiovascular risk profile. OBJECTIVE To compare the cardiovascular risk profile of women with PCOS alone and women with PCOS and NAFLD. DESIGN, SETTING AND PARTICIPANTS Twenty-five oligoanovulatory women with PCOS were screened for NAFLD (including liver biopsy if appropriate) and had their cardiovascular risk factors measured which included the inflammatory marker C-reactive protein (CRP), endothelial function {measured using endoPAT 2000 and serum markers [intracellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), E-selectin and P-selectin]}, clot structure and function [maximum absorbance (MA) and lysis potential (LT)]. RESULTS Twelve patients had confirmed PCOS without evidence of NAFLD, and 13 patients had confirmed PCOS with evidence of NAFLD. The PCOS and NAFLD group were heavier (BMI 43·9 ± 2·2 kg/m(2) ) compared with the PCOS alone group (BMI 37·6 ± 1·4 kg/m(2) P = 0·03). There was no difference in CRP (7·57 ± 0·95 vs 6·59 ± 1·87 mm P = 0·62) or endothelial function (RH-PAT 1·96 ± 0·1 vs 1·74 ± 0·16 P = 0·25), ICAM-1 (221 ± 48 vs 250 ± 60 ng/ml P = 0·19), VCAM-1 (2124 ± 78 vs 2314 ± 91 ng/ml P = 0·13), E-selectin (33·9 ± 3·3 vs 39·5 ± 15·5 ng/ml P = 0·31) and P-selectin (101·0 ± 6·6 vs 95·9 ± 10·2 ng/ml P = 0·69). There was no difference in clot formation or lysis. CONCLUSION The patients with PCOS and NAFLD were heavier compared with patients with PCOS alone. Despite this, we were unable to demonstrate differences in inflammatory markers, endothelial function or clot structure and function, suggesting that severity of steatosis is not the most important determinant of cardiovascular risk in PCOS.

Abstract
Polycystic Ovary Syndrome (PCOS) is the most common cause of subfertility associated to metabolic disorders. The aim of this study was to correlate metabolic and proinflammatory factors in women with PCOS. The frequency of Plasminogen Activator Inhibitor-1 (PAI-1) promoter 4 G/5 G polymorphism was also compared to healthy controls. We evaluated 79 PCOS and 79 healthy women. PAI-1 levels are positively correlated with proinflammatory factors in PCOS group. 4 G allele in PAI-1 gene was more frequent in PCOS and the 4G/4 G genotype was associated with increased PAI-1 levels. A correlation between insulin resistance and proinflammatory and overweight was also observed. C-reactive protein, serum levels of vascular cell adhesion molecule-1 (sVCAM-1), Lipid Accumulation Product (LAP) and vitamin D are good tools to evaluated factors associated to cardiovascular risk in women with PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is considered a complex multifactorial disorder resulting from the interaction of genetic, environmental, and lifestyle influences. Nontargeted proteomics and metabolomics have been used in the past years with the aim of identifying molecules potentially involved in the pathophysiology of this frequent disorder. The biomolecules identified so far participate in many metabolic pathways, including energy metabolism (glucose and lipid metabolism), protein metabolic processes and protein folding, cytoskeleton structure, immune response, inflammation and iron metabolism, fibrinolysis and thrombosis, oxidative stress and intracellular calcium metabolism. These molecules provide key information about molecular functions altered in PCOS and raise questions concerning their precise role in the pathogenesis of this syndrome. The biomolecules identified by nontargeted proteomic and metabolomic approaches should be considered as candidates in future studies aiming to define specific molecular phenotypes of PCOS.

Abstract
OBJECTIVE To evaluate the levels of coagulation and fibrinolytic markers during the first trimester of pregnancy in women with polycystic ovary syndrome (PCOS) and determine the effects of PCOS and obesity on the levels of these hemostatic markers. METHODS A cross-sectional study was conducted in Beijing, China, on women with PCOS (n = 50), healthy women (n = 50), pregnant women with PCOS (n = 50), and healthy pregnant women (n = 50) at 12 weeks of pregnancy. Coagulation and fibrinolytic parameters were measured. RESULTS The interaction between PCOS and pregnancy appears to exert effects on the activities of coagulation factors VIII and X. The interaction between PCOS and obesity also seems to affect the level of von Willebrand factor. CONCLUSIONS Pregnant women with PCOS, especially women who are obese, are observed to be in a more prohemostatic state during the first trimester.

Abstract
Women with polycystic ovary syndrome (PCOS) have chronic low-grade inflammation that can increase the risk of atherothrombosis. We performed a cross-sectional study to examine the effect of glucose ingestion on markers of atherothrombotic inflammation in mononuclear cells (MNC) of 16 women with PCOS (8 lean, 8 obese) and 16 weight-matched controls. Activator protein-1 (AP-1) activation and the protein content of early growth response-1 (EGR-1), matrix matalloproteinases-2 (MMP2), and tissue factor (TF) were quantified from MNC obtained from blood drawn fasting and 2 h after glucose ingestion. Plasma MMP9 and C-reactive protein (CRP) were measured from fasting blood samples. Truncal fat was determined by DEXA. Lean women with PCOS exhibited greater AP-1 activation and MMP2 protein content after glucose ingestion and higher plasma MMP9 and CRP levels than lean controls. Obese women with PCOS exhibited greater EGR-1 and TF protein content after glucose ingestion, and plasma CRP levels were even higher compared with lean subjects regardless of PCOS status. Truncal fat correlated with MMP9 and CRP levels and glucose-stimulated increases in AP-1 activation and EGR-1 and TF protein content. Testosterone correlated with glucose-stimulated AP-1 activation, and androstenedione correlated with MMP9 and CRP levels and glucose-stimulated AP-1 activation. Thus, both PCOS and obesity contribute to an atherothrombotic state in which excess abdominal adiposity and hyperandrogenism may be specific risk factors for developing atherothrombosis.

Abstract
Studying the mechanisms for the complex pathogenesis of polycystic ovary syndrome (PCOS) requires animal models with endocrine, reproductive, and metabolic features of the syndrome. Hyperandrogenism seems to be a central factor in PCOS, leading to anovulation and insulin resistance. In female rats, continuous administration of letrozole, a nonsteroidal inhibitor of P450 aromatase, at 400 μg/d starting before puberty induces hyperandrogenemia and reproductive abnormalities similar to those in women with PCOS. However, despite high circulating testosterone levels, these rats do not develop metabolic abnormalities, perhaps because of their supraphysiological testosterone concentrations or because estrogen synthesis is completely blocked in insulin-sensitive tissues. To test the hypothesis that continuous administration of lower doses of letrozole starting before puberty would result in both metabolic and reproductive phenotypes of PCOS, we performed a 12-wk dose-response study. At 21 d of age, 46 female Wistar rats were divided into two letrozole groups (100 or 200 μg/d) and a control group (placebo). Both letrozole doses resulted in increased body weight, inguinal fat accumulation, anovulation, larger ovaries with follicular atresia and multiples cysts, endogenous hyperandrogemia, and lower estrogen levels. Moreover, rats that received 200 μg/d had insulin resistance and enlarged adipocytes in inguinal and mesenteric fat depots, increased circulating levels of LH, decreased levels of FSH, and increased ovarian expression of Cyp17a1 mRNA. Thus, continuous administration of letrozole, 200 μg/d, to female rats for 90 d starting before puberty results in a PCOS model with reproductive and metabolic features of the syndrome.

Abstract
OBJECTIVE We sought to determine prevalence and likelihood of venous thromboembolism (VTE) among women with and without polycystic ovary syndrome (PCOS). STUDY DESIGN We performed a cross-sectional analysis using Thomson Reuters MarketScan Commercial databases for the years 2003 through 2008. The association between VTE and PCOS among women aged 18-45 years was assessed using age-stratified multivariable logistic regression models. RESULTS Prevalence of VTE per 100,000 was 374.2 for PCOS women and 193.8 for women without PCOS. Compared with women without PCOS, those with PCOS were more likely to have VTE (adjusted odds ratio [aOR] 18-24 years, 3.26; 95% confidence interval [CI], 2.61-4.08; aOR 25-34 years, 2.39; 95% CI, 2.12-2.70; aOR 35-45 years, 2.05; 95% CI, 1.84-2.38). A protective association (odds ratio, 0.8; 95% CI, 0.73-0.98) with oral contraceptive use was noted for PCOS women. CONCLUSION PCOS might be a predisposing condition for VTE, particularly among women aged 18-24 years. Oral contraceptive use might be protective.

Abstract
OBJECTIVE We aimed to assess plasma Von Willebrand factor (vWF) levels in women with polycystic ovary syndrome (PCOS) and to compare these levels among the different PCOS phenotypes. DESIGN We studied 140 women with PCOS and 40 age and body mass index (BMI)- matched healthy women (control group). RESULTS Plasma vWF antigen levels were higher in women with PCOS than in controls (p=0.017). Plasma vWF antigen levels were also higher in patients with phenotypes 1 [i.e. with anovulation (ANOV), biochemical hyperandrogenemia or clinical manifestations of hyperandrogenemia (HA) and polycystic ovaries (PCO)] and 2 (i.e. with ANOV and HA but without PCO) than in controls (p=0.017). In contrast, plasma vWF antigen levels did not differ between controls and patients with phenotypes 3 (i.e. with HA and PCO but without ANOV) and 4 (i.e. with ANOV and PCO but without HA) or between patients with phenotypes 1 and 2 and patients with phenotypes 3 and 4. When overweight/obese and normal weight subjects were analyzed separately, plasma vWF antigen levels did not differ between patients with PCOS (regardless of phenotype) and controls. CONCLUSIONS Plasma vWF levels are elevated in women with PCOS. This increase appears to be more pronounced in women with phenotypes 1 and 2 of PCOS. Given the association between vWF levels and increased incidence of cardiovascular events, the evaluation of vWF levels in women with PCOS might be helpful for cardiovascular risk stratification, but prospective studies are needed to support this hypothesis.

Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS) is a frequent reproductive and metabolic disorder associated with insulin resistance (IR). Berberine (BBR) is an isoquinoline derivative alkaloid extracted from Chinese medicinal herbs that has been used as an insulin sensitizer. BBR may have a potential therapeutic value for PCOS. The aim of this study was to evaluate the effects of BBR in comparison to metformin (MET) on the metabolic features of women with PCOS. DESIGN AND METHODS Eighty-nine subjects with PCOS and IR subjects were randomized into one of three treatment groups: BBR+compound cyproterone acetate (CPA; n=31), MET+CPA (n=30), and placebo+CPA (n=28) for 3 months. Clinical characteristics of the women and metabolic and hormonal parameters were assessed before and after the period of treatment. RESULTS Treatment with BBR in comparison to MET showed decrease in waist circumference and waist-to-hip ratio (WHR; P<0.01), total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDLC; P<0.05) as well as increase in high-density lipoprotein cholesterol (HDLC) and sex hormone-binding globulin (SHBG; P<0.05). Similarly, treatment with BBR in comparison to placebo showed decrease in WHR, fasting plasma glucose, fasting insulin, homeostasis model assessment for IR, area under the curve of insulin, TC, LDLC, and TG (P<0.05) as well as increase in HDLC and SHBG (P<0.01). CONCLUSIONS Intake of BBR improved some of the metabolic and hormonal derangements in a group of treated Chinese women with PCOS. Main effects could be related to the changes in body composition in obesity and dyslipidemia. Further controlled studies are needed for the assessment of the potential favorable metabolic effects of BBR in women with PCOS.

Abstract
OBJECTIVE To investigate the possible effects of low-frequency electroacupuncture (EA) and physical exercise on markers of coagulation and fibrinolysis, insulin sensitivity, and adipose tissue characteristics in women with polycystic ovary syndrome (PCOS). DESIGN Secondary analyses of a prospective, randomized controlled clinical trial. SETTING Department of Physiology and Department of Obstetrics and Gynecology, University of Gothenburg. PATIENT(S) Eighty-four women with PCOS were randomized. INTERVENTION(S) Women with PCOS were randomized to 16 weeks of low-frequency EA (14 treatments), physical exercise (at least 3 times/wk), or no intervention. MAIN OUTCOME MEASURE(S) Anthropometrics, circulating coagulation and fibrinolytic markers, insulin sensitivity (euglycemic hyperinsulinemic clamp), hemodynamics, and adipose tissue morphology/function recorded at baseline, after 16 weeks of intervention, and after a 16-week follow-up. RESULT(S) In the low-frequency EA group, circulating plasminogen activator inhibitor 1 activity decreased by 21.8% after 16 weeks of intervention and by 31.1% at the 16-week follow-up and differed from the physical exercise and the no intervention groups. The EA group had decreases in circulating fibrinogen and tissue plasminogen activator (t-PA), sagittal diameter, and diastolic blood pressure after treatment, and fibrinogen remained lower at the 16-week follow-up. In the physical exercise group, lipoprotein lipase activity increased and diastolic blood pressure decreased after treatment, and both diastolic and systolic blood pressure were lower at follow-up. No other variables were affected. CONCLUSION(S) Low-frequency EA counteracted a possible prothrombotic state in women with PCOS, as reflected by a decrease in plasminogen activator inhibitor 1 activity. Despite within-group improvements, there were no between-group differences in anthropometric, metabolic, or hemodynamic variables after 16 weeks of EA or physical exercise at the dose/intensity studied.
