Abstract
INTRODUCTION Polycystic ovarian syndrome (PCOS) is the commonest endocrine condition affecting reproductive age women. Many biomarkers may aid assessment and management, however evidence is limited on their utility in clinical practice. We conducted a review of systematic reviews to identify the most useful biomarkers in the clinical management of PCOS. METHODS We searched MEDLINE, EMBASE, CENTRAL and HTA until August 2023 for reviews evaluating biomarkers in PCOS women compared to healthy controls. Methodological quality was assessed using the AMSTAR2 tool. We reported pooled evidence for each biomarker with 95% confidence intervals from the most recent, up-to-date, and best quality review. RESULTS From 3360 citations, we included 75 systematic reviews (88 biomarkers, 191,792 women). Most reviews (50/75, 67%) were moderate quality, but reported high heterogeneity (66/75, 88%). We identified 63 abnormal biomarkers in women with PCOS versus healthy controls. Of these, 22 core biomarkers could help evaluate the multisystemic impact of PCOS and inform patient management and surveillance: dehydroepiandrosterone, prolactin, sex hormone-binding globulin, total and free testosterone, anti-Mullerian hormone, systolic and diastolic blood pressure, c-reactive protein, fibrinogen, oral glucose tolerance test, homoeostatic model assessment-insulin resistance index, fasting insulin, total cholesterol, triglycerides, lipoprotein(a), HDL, LDL, non-HDL-cholesterol, ferritin, iron, and 25-hydroxy-vitamin D. CONCLUSION We identified 22 core biomarkers assessing the multisystemic impact of PCOS and inform its clinical management. Future research is required to establish validated healthcare pathways.

Huang X, Yin Z, Xu J, Wu H, Wang Y. The Inflammatory State of Follicular Fluid Combined with Negative Emotion Indicators can Predict Pregnancy Outcomes in Patients with PCOS. Reprod Sci 2024; 31:2493-2507.

Abstract
Polycystic ovary syndrome (PCOS) is a complex endocrine disorder syndrome with an incidence of 6% to 10% in women of reproductive age. Women with PCOS not only exhibit abnormal follicular development and fertility disorders, but also have a greater tendency to develop anxiety and depression. Our aim was to evaluate the ability of inflammatory factors in follicular fluid to predict embryonic developmental potential and pregnancy outcome and to construct a machine learning model that can predict IVF pregnancy outcomes based on indicators such as basic sex hormones, embryonic morphology, the follicular microenvironment, and negative emotion. In this study, inflammatory factors (CRP, IL-6, and TNF-α) in follicular fluid samples obtained from 225 PCOS and 225 non-PCOS women were detected via ELISA. For patients with PCOS, the levels of CRP and IL-6 in the follicular fluid in the pregnant group were significantly lower than those in the nonpregnant group. For non-patients with PCOS, only the level of IL-6 in the follicular fluid was significantly lower in the pregnant group than in the nonpregnant group. In addition, for both PCOS and non-patients with PCOS, compared with those in the pregnant group, patients in the nonpregnant group showed more pronounced signs of anxiety and depression. Finally, the factors that were significantly different between the two subgroups (pregnancy and nonpregnancy) of patients with or without PCOS were identified by an independent sample t test first and further analysed by multilayer perceptron (MLP) and random forest (RF) models to distinguish the two clinical pregnancy outcomes according to the classification function. The accuracy of the RF model in predicting pregnancy outcomes in patients with or without PCOS was 95.6% and 91.1%, respectively. The RF model is more suitable than the MLP model for predicting pregnancy outcomes in IVF patients. This study not only identified inflammatory factors that can affect embryonic development and assessed the anxiety and depression tendencies of PCOS patients, but also constructed an AI model that predict pregnancy outcomes through machine learning methods, which is a beneficial clinical tool.

Abstract
Fibrinolytic enzymes modify various substrates required for tissue remodeling, playing a crucial role in mechanisms underlying resilience, reward processing, ovulation, embryo implantation, and placentation. Individuals with low resilience and reduced reward responsiveness, when exposed to chronic stress, are at increased risk of experiencing a range of negative emotions. Chronic anxiety and melancholia are examples of negative emotions associated with hypercortisolism, while fear and atypical depression are characterized by systemic inflammation. Both cortisol and inflammatory cytokines stimulate the production of plasminogen activator inhibitor-1 (PAI-1), a potent fibrinolysis inhibitor. Chronic anxiety, fear, and depression are among the many hypofibrinolytic conditions increasing the risk of oligo-anovulation, miscarriage, fetal growth restriction, and preeclampsia. Although significant, the impact of negative emotions on implantation is not as obvious as on ovulation or placentation. Other hypofibrinolytic conditions that may affect female reproduction through mechanisms dependent or independent of PAI-1 include metabolic disturbances (e.g., due to consumption of highly palatable foods, often used to alleviate negative affect), inflammation, hyperhomocysteinemia, hypothyroidism, hypercortisolism, antiphospholipid antibodies, and the 4G allele of the PAI-1 gene. Benzodiazepines and antidepressants should be used with caution in the first trimester as this combination may cause malformations. Also, selective serotonin reuptake inhibitors have fibrinolytic properties that increase the risk of bleeding after surgical procedures. Psychological interventions, especially group therapy, are effective in the prevention of reproductive disorders. Controlled trials are needed to test the hypothesis that female reproductive health depends on psychological well-being, a balanced diet and physical activity, suppression of inflammation and autoantibodies, and homocysteine and hormonal homeostasis.

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

Abstract
Polycystic ovary syndrome (PCOS) refers to a condition that often has 'poly' liquid containing sacks around ovaries. It affects reproductive-aged females giving rise to menstrual and related reproductive issues. PCOS is marked by hormonal imbalance often resulting in hyperandrogenism. Inflammation is now considered a central manifestation of this disease with several inflammatory biomarkers such as TNF-α, C-reactive protein and Interleukins-6/18 found to be particularly elevated in PCOS patients. Diagnosis is often late, and MRI-based diagnosis, along with blood-based analyses, are still the best bet for a definitive diagnosis. Radiomics also offers several advantages and should be exploited to the maximum. The mechanisms of PCOS onset and progression are not very well known but pituitary dysfunction and elevated gonadotrophin releasing hormone resulting in high levels of luteinizing hormone are indicative of an activated hypothalamic-pituitary-ovarian axis in PCOS. A number of studies have also identified signaling pathways such as PI3K/Akt, NF-κB and STAT in PCOS etiology. The links of these signaling pathways to inflammation further underline the importance of inflammation in PCOS, which needs to be resolved for improving patient outcomes.

[PMID: 38397957 PMCID: PMC10886802 DOI: 10.3390/biomedicines12020355] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Revised: 01/31/2024] [Accepted: 02/01/2024] [Indexed: 02/25/2024] Open
Abstract
Background: Oncostatin M, a novel adipokine, plays a role in oogenesis, lipogenesis, and inflammation and may contribute to polycystic ovary syndrome pathogenesis and related metabolic problems. Adipokines are believed to contribute to developing polycystic ovary syndrome and its accompanying metabolic parameters, such as dyslipidemia, insulin resistance, and cardiovascular diseases. Methods: In this case-control study, the patients were grouped in a 1:1 ratio into either the polycystic ovary syndrome (n = 32) or the control group (n = 32). Serum levels of fasting glucose, insulin, C-reactive protein, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglyceride, white blood cell count, thyroid-stimulating hormone, luteinizing hormone, follicle-stimulating hormone, total testosterone, prolactin, estradiol, homeostasis model assessment of insulin resistance, and oncostatin M were analyzed. Results: Oncostatin M levels were significantly lower, but C-reactive protein levels were substantially higher in the polycystic ovary syndrome group than in the control group (p = 0.002, p = 0.001, respectively). Oncostatin M was inversely correlated with total cholesterol, non-high-density lipoprotein cholesterol, fasting glucose, and the luteinizing hormone/follicle-stimulating hormone ratio (ρ = -0.329, p =0.017; ρ = -0.386, p = 0.005; ρ = -0.440, p = 0.001; ρ = -0.316, p = 0.023, respectively). Conversely, there was no correlation between oncostatin M and total testosterone level (ρ = 0.220; p = 0.118). In the context of inflammation and metabolic parameters, oncostatin M was inversely correlated with C-reactive protein, homeostatic model assessment for insulin resistance score, and low-density lipoprotein cholesterol (ρ = -0.353, p = 0.019; ρ = -0.275, p = 0.048; ρ = -0.470, p < 0.001, respectively). Conclusions: Plasma oncostatin M levels were considerably lower in patients with polycystic ovary syndrome than in the control group, and this was inversely correlated with the hormonal and metabolic parameters of polycystic ovary syndrome. Thus, oncostatin M may be a novel therapeutic target for polycystic ovary syndrome and its metabolic parameters.

Abstract
INTRODUCTION The polycystic ovary syndrome (PCOS) may represent an important model of lipid alterations. Lipoprotein(a) [Lp(a)] has emerged as a new marker of cardiovascular risk. AIM The main objective of this meta-analysis was to analyze the available evidence on Lp(a) levels in patients with PCOS compared to a control group. METHODS This meta-analysis was performed according to PRISMA guidelines. A literature search was performed to detect studies that have quantified Lp(a) levels in women with PCOS compared to a control group. The primary outcome was Lp(a) levels expressed in mg/dL. Random effects models were used. RESULTS Twenty-three observational studies including 2,337 patients were identified and considered eligible for this meta-analysis. In the overall analysis, the quantitative analysis showed that patients with PCOS have a higher Lp(a) levels (SMD: 1.1 [95% CI: 0.7 to 1.4]; I2=93%) compared to the control group. The results were similar in the analysis of the subgroups of patients according to body mass index (normal weight group: SMD: 1.2 [95% CI: 0.5 to 1.9], I2=95%; overweight group: SMD: 1.2 [95% CI: 0.5 to 1.8], I2=89%). Sensitivity analysis showed that the results were robust. CONCLUSIONS This meta-analysis shows that women with PCOS had higher levels of Lp(a) compared to healthy women used as a control group. These findings were observed in both overweight and non-overweight women.

Abstract
Polycystic ovary syndrome (PCOS) is the most common reproductive endocrine disorder affecting women, which can lead to infertility. Infertility, obesity, hirsutism, acne, and irregular menstruation are just a few of the issues that PCOS can be linked to. PCOS has a complicated pathophysiology and a range of clinical symptoms. Chronic low-grade inflammation is one of the features of PCOS. The inflammatory environment involves immune and metabolic disturbances. Numerous organ systems across the body, in addition to the female reproductive system, have been affected by the pathogenic role of immunological dysregulation in PCOS in recent years. Insulin resistance and hyperandrogenism are associated with immune cell dysfunction and cytokine imbalance. More importantly, obesity is also involved in immune dysfunction in PCOS, leading to an inflammatory environment in women with PCOS. Hormone, obesity, and metabolic interactions contribute to the pathogenesis of PCOS. Hormone imbalance may also contribute to the development of autoimmune diseases. The aim of this review is to summarize the pathophysiological role of immune dysregulation in various organ systems of PCOS patients and provide new ideas for systemic treatment of PCOS in the future.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive-aged individuals with ovaries. It is associated with anovulation and increased risk to fertility and metabolic, cardiovascular, and psychological health. The pathophysiology of PCOS is still inadequately understood, although there is evidence of persistent low-grade inflammation, which correlates with associated visceral obesity. Elevated proinflammatory cytokine markers and altered immune cells have been reported in PCOS and raise the possibility that immune factors contribute to ovulatory dysfunction. Because normal ovulation is modulated by immune cells and cytokines in the ovarian microenvironment, the endocrine and metabolic abnormalities associated with PCOS orchestrate the accompanying adverse effects on ovulation and implantation. This review evaluates the current literature on the relationship between PCOS and immune abnormalities, with a focus on emerging research in the field.

Abstract
Rising rates of chronic conditions were cited as one of the key public health concerns in the Fiscal Year (FY) 2021 U.S. Senate and House of Representatives appropriations bills, where a review of current National Institutes of Health (NIH) portfolios relevant to research on women's health was requested. Chronic conditions were last defined by the US Department of Health and Human Services (HHS) in 2010. However, existing definitions of chronic conditions do not incorporate sex or gender considerations. Sex and gender influence health, yet significant knowledge gaps exist in the evidence-base for prevention, diagnosis, and treatment of chronic diseases amongst women. The presentation, prevalence, and long-term effects of chronic conditions and multimorbidity differs in women from men. A clinical framework was developed to adequately assess the NIH investment in research related to chronic conditions in women. The public health needs and NIH investment related to conditions included in the framework were measured. By available measures, research within the NIH has not mapped to the burden of chronic conditions among women. Clinical research questions and endpoints centered around women can be developed and implemented; clinical trials networks with expanded or extended eligibility criteria can be created; and data science could be used to extrapolate the effects of overlapping or multiple morbidities on the health of women. Aligning NIH research priorities to address the specific needs of women with chronic diseases is critical to addressing women's health needs from a life course perspective.

Abstract
Studies have shown an increased risk of coronary artery disease (CAD) in the human immunodeficiency virus (HIV) population. Epicardial fat (EF) quality may be linked to this increased risk. In our study, we evaluated the associations between EF density, a qualitative characteristic of fat, and inflammatory markers, cardiovascular risk factors, HIV-related parameters, and CAD. Our study was cross-sectional, nested in the Canadian HIV and Aging Cohort Study, a large prospective cohort that includes participants living with HIV (PLHIV) and healthy controls. Participants underwent cardiac computed tomography angiography to measure volume and density of EF, coronary artery calcium score, coronary plaque, and low attenuation plaque volume. Association between EF density, cardiovascular risk factors, HIV parameters, and CAD were evaluated using adjusted regression analysis. A total of 177 PLHIV and 83 healthy controls were included in this study. EF density was similar between the two groups (-77.4 ± 5.6 HU for PLHIV and -77.0 ± 5.6 HU for uninfected controls, P = .162). Multivariable models showed positive association between EF density and coronary calcium score (odds ratio, 1.07, P = .023). Among the soluble biomarkers measured in our study, adjusted analyses showed that IL2Rα, tumor necrosis factor alpha and luteizing hormone were significantly associated with EF density. Our study showed that an increase in EF density was associated with a higher coronary calcium score and with inflammatory markers in a population that includes PLHIV.

Abstract
PURPOSE OF REVIEW Polycystic ovary syndrome (PCOS), which is common in women of reproductive age worldwide, is a syndrome that reduces the lifelong quality of life and poses a significant risk for various diseases. PCOS is a combination of symptoms of hyperandrogenism, oligo-anovulation, and polycystic ovarian morphology (PCOM). In PCOS, which is characterized by chronic low-grade inflammation, some inflammatory cytokines are increased. This review aimed to explain possible mechanisms of inflammation in PCOS and the effects of Mediterranean diet components on reducing this inflammation. RECENT FINDINGS Although the exact mechanisms of inflammation in PCOS are not yet fully known, it is stated that it is mediated by obesity, insulin resistance, and high androgen concentration. This inflammatory state negatively impacts the risk of future health problems and the quality of life of PCOS. Therefore, strategies to reduce inflammation are thought to be important. Dietary adjustments have important effects in reducing this inflammation and preventing disease. At this point, the Mediterranean diet, which has been proven to have a protective effect against many diseases, draws attention. Among the components of the Mediterranean diet, especially omega-3, antioxidants and dietary fiber may contribute to the reduction of inflammation through different mechanisms. PCOS is characterized by chronic low-grade inflammation, which increases women's risk of health problems, both now and in the future. Reducing inflammation is therefore extremely important, and it can be achieved with adherence to the Mediterranean diet. Inflammation pathways and the effect of the components of the Mediterranean diet in PCOS. AGE, advanced glycation end products; NF-κB, nuclear factor kappa-B. Obesity, insulin resistance, and hyperandrogenism may cause inflammation in PCOS through different mechanisms. Antioxidants, omega-3, and dietary fiber, which are the main components of the Mediterranean diet, may be effective in reducing this inflammation in PCOS. (Created with BioRender.com).

Abstract
BACKGROUND Low temperature plasma (LTP) exerts a protective effect in inflammation via enhancing MANF expression. Hyperactivation and dysfunction of theca cells induced by inflammatory agents is accompanied by polycystic ovary syndrome (PCOS), which is a common reproductive and endocrine disorder. However, the effect of LTP on theca cells is still unknown. METHODS AND RESULTS Theca cells were stimulated with IL-1β or TNF-α for 12 h, then treated with LTP for 100 s. After 8 h, medium supernatant and theca cells were collected. Production of androgen from theca cells were detected by ELISA. The PCNA and Annexin V levels in theca cells were detected by using immunofluorescent staining. The levels of PCNA, BCL-2 and BAX were evaluated by western blot and qPCR. MTT assay was used to detect the viability of theca cells. The proportions of apoptosis of theca cells were detected by Flow cytometry. The mRNA levels of androgenic genes were detected by qPCR. The MANF levels in medium supernatant and cell lysate were detected by using ELISA, western and qPCR. BIP and CHOP expressions were detected by using western blot and qPCR. We found that LTP irradiation decreased inflammatory agents-induced upregulation of androgen and androgenic genes in theca cells. And LTP irradiation relieves IL-1β or TNF-α-induced pathological proliferation and apoptosis in theca cells. In terms of mechanism, LTP irradiation increased MANF level in theca cells to inhibit BIP and CHOP expression. CONCLUSION These evidences suggest the protective effect of LTP on theca cells in inflammatory microenvironment, and LTP has the potential clinical application of PCOS.

Abstract
As a complex endocrine and metabolic condition, polycystic ovarian syndrome (PCOS) affects women's reproductive health. These common symptoms include hirsutism, hyperandrogenism, ovulatory dysfunction, irregular menstruation, and infertility. No one knows what causes it or how to stop it yet. Alterations in gut microbiota composition and disruptions in secondary bile acid production appear to play a causative role in developing PCOS. PCOS pathophysiology and phenotypes are tightly related to both enteric and vaginal bacteria. Patients with PCOS exhibit changed microbiome compositions and decreased microbial diversity. Intestinal microorganisms also alter PCOS patient phenotypes by upregulating or downregulating hormone release, gut-brain mediators, and metabolite synthesis. The human body's gut microbiota, also known as the "second genome," can interact with the environment to improve metabolic and immunological function. Inflammation is connected to PCOS and may be caused by dysbiosis in the gut microbiome. This review sheds light on the recently discovered connections between gut microbiota and insulin resistance (IR) and the potential mechanisms of PCOS. This study also describes metabolomic studies to obtain a clear view of PCOS and ways to tackle it.

Abstract
In brief A genetic, epigenetic, and environmental association exists between oxidative stress (OS) and polycystic ovary syndrome (PCOS), expressed in a multifaceted clinical profile. This review summarizes and discusses the role of OS in the pathogenesis of PCOS syndrome, focusing on metabolic, reproductive, and cancer complications. Abstract Oxidative stress (OS), an imbalance between oxidants and antioxidants in cells, is one of many factors playing essential roles in the pathogenesis of polycystic ovary syndrome (PCOS). PCOS is described mainly as a disproportion of reproductive hormones, leading to chronic anovulation and infertility in women. Interestingly, OS in PCOS may be associated with many disorders and diseases. This review focuses on characteristic markers of OS in PCOS and the relationship between OS and PCOS related to insulin resistance (IR), hyperandrogenemia, obesity, chronic inflammation, cardiovascular diseases, and cancer. Interestingly, in patients with PCOS, an increase in oxidative status and insufficient compensation of the increase in antioxidant status before any cardiovascular complications are observed. Moreover, free radicals promote carcinogenesis in PCOS patients. However, despite these data, it has not been established whether oxygen stress influences PCOS development or a secondary disorder resulting from hyperglycemia, IR, and cardiovascular and cancer complications in women.

Abstract
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.

Abstract
Context Hyperandrogenism is a central feature of polycystic ovary syndrome (PCOS). In vitro studies have demonstrated that inflammatory stimuli promote whereas ibuprofen inhibits androgen production by ovarian theca-interstitial cells. Objective This work aimed to determine the effects of nonselective inhibitor of cyclooxygenases COX-1 and COX-2 on testosterone levels. Methods A prospective pilot study took place in an academic hospital of women with PCOS defined according to Rotterdam criteria (N = 20). Evaluations were taken at baseline and after 3 weeks of ibuprofen administration (400 mg twice a day or 400 mg 3 times a day, respectively, in women with weight < and ≥ 70 kg). The main outcome measure was total serum testosterone. Results Ibuprofen administration was associated with a decline of total testosterone from 0.75 ± 0.06 ng/mL to 0.59 ± 0.05 ng/mL (P = .008). There was no statistically significant change in the levels of other relevant hormones including dehydroepiandrosterone sulfate, gonadotropins, and insulin. Multiple regression analysis identified the greatest decline of testosterone was independently predicted by baseline testosterone level (P = .004) and by baseline insulin sensitivity index (P = .03). Conclusion Nonselective inhibition of COX-1 and COX-2 leads to selective reduction of testosterone consistent with direct inhibitory effect on ovarian steroidogenesis.

Abstract
Men seem to have a higher intrinsic risk of venous thromboembolism (VTE) than women, regardless of age. To date, this difference has not been explained. By integrating state‐of‐the‐art research presented at the International Society on Thrombosis and Haemostasis Congress of 2021 with the available literature, we address potential explanations for this intriguing risk difference between men and women. We discuss the role of exogenous and endogenous sex hormones as the most important known sex‐specific determinants of VTE risk. In addition, we highlight clues on the role of sex hormones and VTE risk from clinical scenarios such as pregnancy and the polycystic ovary syndrome. Furthermore, we address new potential sex‐specific risk factors and unanswered research questions, which could provide more insight in the intrinsic risk difference between men and women, such as body height and differences in body fat distribution, leading to dysregulation of metabolism and inflammation.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a kind of endocrine and metabolic disorder, disturbing the females of reproductive age. Here, we aimed to investigate the metabolic characteristics of overweight women with PCOS and analyze the possible mechanisms. METHODS We conducted a cross-sectional study on 947 patients with PCOS, who were classified according to body mass index (BMI) as overweight (BMI ≥ 24 kg/m2) or non-overweight (BMI ≤ 23.9 kg/m2). The clinical symptoms, endocrine features, metabolic status, and inflammatory levels of the patients were comprehensively assessed and compared between the patients of the two groups. Additionally, a predictive study on the correlation between inflammation and metabolism was performed using STRING and Cytoscape software, and the possible mechanisms of metabolic disorders involved in the overweight PCOS were preliminarily explored. RESULTS Overweight PCOS was associated with increased average age, waist-to-hip ratio, and the incidence of acanthosis nigricans. These patients were susceptible to familial hypertension and diabetes, and exhibited evident characteristics of low levels of luteinizing hormone (LH) and the ratio of LH to follicle-stimulating hormone, and were more inclined to insulin resistance (IR). Furthermore, overweight PCOS presented with a chronic low-grade inflammation state with increased levels of inflammatory cytokines complement components C5/C5α, CXCL12/SDF-1, MIF, and Serpin E1/PAI-1 evidently compared with those in non-overweight PCOS. Pearson analysis showed that these inflammatory cytokines were directly or indirectly correlated with IR. The STRING and Cytoscape network analysis predicted that inflammatory cytokines CXCL12/SDF-1, Serpin E1/PAI-1 and MIF might be crucial for inducing IR in overweight PCOS women through various biological functions and signal transductions including the JAK-STAT cascade, ATP biosynthesis, and HIF-1 signaling. CONCLUSIONS Overweight patients with PCOS are prone to low gonadal levels, IR, and chronic low-grade inflammation. Inflammatory cytokines CXCL12/SDF-1, Serpin E1/PAI-1and MIF might lead to IR through multiple biological functions and signal transductions in overweight PCOS.

Abstract
Objectives: Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in infertile women characterized by both reproductive and metabolic dysfunctions of different degrees. Furthermore, it has been associated with increased cardiovascular disease (CVD) risk and related long-term health sequela. The aim of this study is to evaluate serum homocysteine (Hcy) and C-reactive protein (CRP) levels in women with PCOS and to evaluate their relationship with clinical and laboratory parameters in women with PCOS. Materials and Methods: The prospective single-center study included 45 women with PCOS (study group) and 41 control subjects. Demographic variables and Hcy, CRP, fasting blood glucose, insulin, follicle-stimulating hormone, luteinizing hormone, estradiol, total and free testosterone, dehydroepiandrosterone sulfate, thyroid-stimulating hormone levels, and lipid profiles of the subjects were recorded. homeostatic model assessment for insulin resistance (HOMA-IR) indexes were calculated. Results: Fasting plasma glucose, insulin, HOMA-IR, free and total testosterone levels, and clinical hirsutism were significantly higher in the study group. There was no statistically significant difference in lipid profile between groups. Hcy and CRP levels were higher in the study group, which was not statistically significantly different (P > 0.05). Conclusion: Some of the parameters that are correlated with CVD risk were found to be higher in women with PCOS, although the difference for Hcy and CRP did not reach statistical significance. However, the current study reveals that the CVD risk associated with PCOS deserves more comprehensive prospective studies with long-term outcomes.

Abstract
Polycystic ovary syndrome (PCOS) is a common endocrinopathy in women of reproductive age. Although its essential clinical manifestation includes a plethora of symptoms and signs, which largely reflects the underlying hyperandrogenism, oligo/anovulation, and polycystic ovarian morphology, PCOS may also be associated with many metabolic derangements. These metabolic derangements happen to overlap with many of the core constituents of the metabolic syndrome (MBS)—increased insulin resistance, central obesity, and dyslipidemia. The two disorders also display similarly increased risks for certain metabolic and vascular diseases, such as type 2 diabetes mellitus, hypertension, and cardiovascular diseases. Due to the many similarities between metabolic syndrome and PCOS, this review aims to examine the evidence concerning the overlapping features, the risks for comorbidities, possible shared mechanisms, and treatment strategies in patients with coexisting PCOS and MBS.

Abstract
PURPOSE Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies affecting women of reproductive age and leads to metabolic disorders and infertility. The present study was conducted to investigate the therapeutic effects of curcumin (Cur) encapsulated arginine (Arg) and N-acetyl histidine (NAcHis) modified chitosan (Arg-CS-NAcHis/Cur) nanoparticles (NPs). METHODS In this study, amphiphilic chitosan (CS) conjugate was developed by modification with hydrophilic arginine (Arg) and hydrophobic N-acetyl histidine (NAcHis) group (Arg-CS-NAcHis). The synthesized conjugate was well characterized by FTIR and NMR studies. Self-assembled nanoparticles based on the synthesized conjugate were developed by simple sonication method and characterized for the physicochemical properties of zeta potential, particle size and drug encapsulation. Next, in vitro drug release, cytotoxicity, and cellular uptake studies of the NPs were evaluated. Finally, the developed nanoparticles were examined for their therapeutic potential against estradiol valerate (EV) induced PCOS rats by evaluating hormone level changes and ovarian morphology. RESULTS The results showed that zeta potential of the nanoparticles was 39.8±2.52 mV and the average size was 200 nm. The in vitro drug release profile showed sustained release pattern. Cytotoxicity and cellular uptake studies also showed preferential effectiveness than free curcumin. Both the biochemical and histopathological studies showed positive effects in reverting the symptoms of PCOS rats to normalcy. CONCLUSION Curcumin encapsulated arginine and N-acetyl histidine modified chitosan (Arg-CS-NAcHis/Cur) nanoparticles have been successfully developed. The present study suggested that treatment of the nanoparticles might reverse many of the PCOS symptoms. Therefore, these nanoparticles might be used as promising new candidate for delivery of curcumin to treat PCOS.

Abstract
To study and critically analyze the published evidence on correlation of hormonal abnormalities and endothelial dysfunction (ED) in polycystic ovary syndrome (PCOS) through a systematic review. The databases including MEDLINE, PubMed, Up-To-Date, and Science Direct were searched using Medical subject handling terms and free text term keywords such as endocrine abnormalities in PCOS, ED assessment in PCOS, ED in combination with insulin resistance (IR), hyperandrogenism (HA), increased free testosterone, free androgen index (FAI), gonadotrophin levels, luteinizing hormone (LH), prolactin, estrogen, adipocytokines to search trials, and observational studies published from January 1987 to September 2015. Authors of original studies were contacted for additional data when necessary. PCOS increases the risk of cardiovascular disease in women. ED, which is a reliable indicator of cardiovascular risk in general population, is seen in most (but not all) women with PCOS. IR, seen in 70% patients with PCOS, is associated with ED in these women, but patients can have normal endothelial function even in the presence of IR. Free testosterone and FAI are consistently associated with ED, but endothelial function can be normal despite HA. Estradiol (not estrone) appears to be protective against ED though estrone is the predominant estrogen produced in PCOS. Increased levels of adipocytokines (visfatin) are promising in predicting ED and cardiovascular risk. However, more studies are required focusing on direct correlation of levels of prolactin, LH, estrone, and visfatin with ED in PCOS.

Abstract
OBJECTIVE To study the effects of ibuprofen on androgen production, gene expression, and cell viability in rat theca-interstitial cells exposed to the proinflammatory stimuli interleukin-1β (IL-1β) and lipopolysaccharide (LPS). DESIGN Animal study. SETTING University-based research laboratory. PATIENTS/ANIMALS Theca-interstitial cells were isolated from 30 day old female Sprague Dawley rats. INTERVENTIONS Theca cells were cultured with pro-inflammatory media containing IL-1β and LPS and compared with cells cultured in control media. MAIN OUTCOME MEASURES Androstenedione quantification was performed on conditioned cell culture medium using liquid chromatography-mass spectrometry. Theca cell viability was assessed using PrestoBlue cell viability assay. The gene expression of Cyp17a1, Cyp11a1, and Hsd3b was analyzed using quantitative polymerase chain reaction. RESULTS Both proinflammatory stimuli IL-1β and LPS increased androstenedione concentration in cell culture medium, and these effects were mitigated with ibuprofen. Both inflammatory agents in addition increased the expression of key genes involved in androgen synthesis: Cyp17a1, Cyp11a1, and Hsd3b; the addition of ibuprofen to the culture medium inhibited these effects. Theca cell viability increased with IL-1β and LPS. Ibuprofen inhibited the IL-1β-mediated increase in cell viability but did not reverse the effects of LPS. CONCLUSIONS In conclusion, our findings support the hypothesis that many of the alterations induced by inflammatory stimuli in theca-interstitial cells are abrogated by the addition of ibuprofen.

Abstract
AIM To investigate the connection of alpha-1 acid glycoprotein inflammatory biomarker with clinical, hormonal, and metabolic characteristics in women with polycystic ovary syndrome (PCOS) and normal cycling controls. METHODS A cross-sectional study was conducted on 235 women with PCOS and 92 normal cycling controls attended between 2008 and 2018. Alpha-1 acid glycoprotein levels were correlated with clinical, anthropometric, anthropometric-metabolic indexes, and hormones of women with PCOS and controls. Simple and multivariate stepwise linear regression, matched for age and body mass index confounding variables, was performed. RESULTS Alpha-1 acid glycoprotein levels were higher in women with PCOS (p = 0.0016). In controls, it was positively correlated with waist circumference, fat mass, body adiposity index, and lipid accumulation product, and negatively correlated with sex hormone-binding globulin (p < 0.005 for all comparisons). In PCOS, it was positively correlated with testosterone, most biomarkers of central adiposity, homeostatic model assessment of insulin-resistant, erythrocyte sedimentation rate, and negatively correlated with sex hormone-binding globulin, high-density lipoprotein cholesterol, glucose/insulin ratio, and lymphocytes (p < 0.055 for all comparisons). After multivariate regression in women with PCOS, alpha-1 acid glycoprotein retained a significant positive correlation with erythrocyte sedimentation rate and C-reactive protein. CONCLUSIONS In PCOS, alpha-1 acid glycoprotein is correlated with biomarkers of adiposity, carbohydrate metabolism, and total testosterone. This inflammatory marker is also correlated with erythrocyte sedimentation rate, neutrophils, and lymphocytes, frequent markers of an inflammation state.

Abstract
STUDY QUESTION Is polycystic ovary syndrome (PCOS) associated with an elevation of markers of endotoxemia? SUMMARY ANSWER In women with PCOS serum levels of lipopolysaccharides (LPS), the LPS to high-density lipoprotein (HDL) ratio and LPS-binding protein (LBP) are significantly greater than those of normal control subjects. WHAT IS KNOWN ALREADY Mononuclear cells from women with PCOS respond excessively to LPS by releasing pro-inflammatory cytokines. In rat ovarian theca-interstitial cell cultures LPS stimulates androgen production. STUDY DESIGN, SIZE, DURATION Cross-sectional study comparing markers of endotoxemia in women with PCOS (n = 62), healthy ovulatory women with polycystic ovary morphology (PCOM, n = 39) and a control group of healthy ovulatory women without PCOM [normal (NL), n = 43]. PARTICIPANTS/MATERIALS, SETTING, METHODS LPS was measured using a chromogenic assay. LBP was measured by ELISA. Total cholesterol and lipids were measured using a homogeneous enzyme colorimetric method. Androgens, gonadotrophins, prolactin, insulin, high-sensitivity C-reactive protein (hs-CRP) and sex hormone-binding globulin were determined by electrochemiluminescence assays. Glucose was measured using an enzymatic reference method with hexokinase. MAIN RESULTS AND THE ROLE OF CHANCE Women with PCOS, when compared with NL subjects, had a significantly higher mean LPS (P = 0.045), LPS/HDL ratio (P = 0.007) and LBP (P = 0.01). Women with PCOM had intermediate levels of markers of endotoxemia. Comparison among all groups revealed that markers of endotoxemia correlated positively with testosterone level, ovarian volume, number of antral follicles and hirsutism score, but negatively with the number of spontaneous menses per year. In multiple regression analysis, all measures of endotoxemia correlated independently and positively with hs-CRP and with ovarian volume. LIMITATIONS, REASONS FOR CAUTION This cross-sectional study reveals that markers of endotoxemia are associated with several clinical features observed in women with PCOS. However, responsible mechanisms and causation remain unknown. Steroid quantification was carried out by electrochemiluminescence assays and not by the current gold standard: liquid chromatography-mass spectrometry. Hence, the relationship of endotoxemia with features of PCOS and the extent to which endotoxemia contributes to reproductive and metabolic dysfunction warrants further investigation. WIDER IMPLICATIONS OF THE FINDINGS This study reveals the novel observation that markers of endotoxemia are elevated in young and otherwise healthy women with PCOS without significant metabolic dysfunction. Moreover, the association of clinical and endocrine markers of PCOS with those of endotoxemia may represent a pathophysiologic link to reproductive dysfunction as well as metabolic and long-term cardiovascular risks associated with this disorder. STUDY FUNDING/COMPETING INTEREST(S) Intramural funding from Poznan University of Medical Sciences. The authors have no conflicts of interest to declare. TRIAL REGISTRATION NUMBER N/A.

Abstract
Polycystic ovary syndrome (PCOS) is a one of the most common endocrine disorders, with a prevalence rate of 5–10% in reproductive aged women. It’s characterized by (1) chronic anovulation, (2) biochemical and/or clinical hyperandrogenism, and (3) polycystic ovarian morphology. PCOS has significant clinical implications and can lead to health problems related to the accumulation of adipose tissue, such as obesity, insulin resistance, metabolic syndrome, and type 2 diabetes. There is also evidence that PCOS patients are at higher risk of cardiovascular diseases, atherosclerosis, and high blood pressure. Several studies have reported the association between polycystic ovary syndrome (PCOS) and low-grade chronic inflammation. According to known data, inflammatory markers or their gene markers are higher in PCOS patients. Correlations have been found between increased levels of C-reactive protein (CRP), interleukin 18 (IL-18), tumor necrosis factor (TNF-α), interleukin 6 (IL-6), white blood cell count (WBC), monocyte chemoattractant protein-1 (MCP-1) and macrophage inflammatory protein-1α (MIP-1α) in the PCOS women compared with age- and BMI-matched controls. Women with PCOS present also elevated levels of AGEs and increased RAGE (receptor for advanced glycation end products) expression. This chronic inflammatory state is aggravating by obesity and hyperinsulinemia. There are studies describing mutual impact of hyperinsulinemia and obesity, hyperandrogenism, and inflammatory state. Endothelial cell dysfunction may be also triggered by inflammatory cytokines. Many factors involved in oxidative stress, inflammation, and thrombosis were proposed as cardiovascular risk markers showing the endothelial cell damage in PCOS. Those markers include asymmetric dimethylarginine (ADMA), C-reactive protein (CRP), homocysteine, plasminogen activator inhibitor-I (PAI-I), PAI-I activity, vascular endothelial growth factor (VEGF) etc. It was also proposed that the uterine hyperinflammatory state in polycystic ovary syndrome may be responsible for significant pregnancy complications ranging from miscarriage to placental insufficiency. In this review, we discuss the most importance evidence concerning the role of the process of chronic inflammation in pathogenesis of PCOS.

J Obstet Gynaecol Res 2021; 47:1804-1816. [PMID: 33650273 DOI: 10.1111/jog.14725] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Revised: 01/09/2021] [Accepted: 02/11/2021] [Indexed: 12/30/2022]
Abstract
PURPOSE Metformin is widely used as an insulin sensitizer in polycystic ovary syndrome (PCOS) patients. However, previous studies have found that the effect of metformin on the level of homocysteine were not consistent in PCOS patients. The aim of this review was to analyze the effect of metformin on homocysteine levels in patients with PCOS patients. METHODS The Cochrane Library, Pubmed, and Web of Science were searched according to predefined search terms. There is no restriction for publication time and language. RESULTS Eleven studies were included and the data were extracted. The homocysteine level in PCOS patients was significantly increased after taking metformin (mean difference [MD] -1.33; 95% confidence interval [CI] -2.16 to -0.49, p = 0.002). Subgroup analysis showed that the level of homocysteine was generally increased in PCOS patients with body mass index (BMI) ≥25 after taking metformin alone (MD -1.82; 95% CI -2.56 to -1.07, p < 0.00001). There was no significant change in homocysteine level in PCOS patients with BMI <25 (MD 0.69; 95% CI -0.41 to 1.79, p = 0.22). Subgroup analysis showed that there was no significant difference when taking metformin >3 months or taking metformin ≤3 months (p = 0.84). Taking metformin ≥1700 mg/days significantly increased homocysteine levels in PCOS patients (MD -2.05; 95% CI -2.40 to -1.70, p < 0.00001). When taking metformin <1700 mg/days, there was no significant difference in homocysteine level in PCOS patients (MD 0.15; 95% CI -1.06 to 1.37, p = 0.80). The difference between the two subgroups was significant (p = 0.0006). There was no significant difference in vitamin B12 level before and after metformin treatment (MD 24.70; 95% CI -22.54 to 71.93, p = 0.31). There was a decrease in serum folic acid level after metformin administration (MD 1.03; 95% CI 0.80 to 1.26, p < 0.00001). CONCLUSION Taking metformin alone increased homocysteine levels and decreased folic acid levels in nonpregnant PCOS patients. And, it was suggested that the dosage of metformin should be less than 1700 mg/days. The supplement of folic acid and B vitamins during metformin administration may be essential in nonpregnant PCOS patients. We should pay much attention to the potential effect of metformin in PCOS patients.

Abstract
OBJECTIVE To evaluate the relationship between plasma levels of the inflammatory markers tumor necrosis factor-alpha (TNF-α), C reactive protein (CRP), and interlukin-6 (IL-6) with insulin resistance in Saudi women with polycystic ovaries syndrome (PCOS). METHODS One hundred eighty Saudi women with and without PCOS, aged 22-38 years, were randomly recruited in this age and body mass index matched case-control study. Clinical assessment, anthropometric measurements, and biochemical parameters were determined for all study participants. RESULTS Levels of TNF-α, IL-6, hs-CRP, insulin, and insulin resistance indices were significantly higher among PCOS group than their age and BMI matched controls (p < 0.05). Results showed that only QUICK-I (β = -0.247, p < 0.0001, 95% CI: -3.009 to -0.977) independently predicted TNF-α levels after adjustment for potential confounders. CONCLUSIONS Elevated plasma levels of TNF- α and IL-6 among PCOS women reflects a state of chronic inflammation with potential implication for insulin resistance, independent of obesity.

Abstract
PURPOSE This review aims to summarize the key findings of several miRNAs and their roles in polycystic ovary syndrome with insulin resistance, characterize the disease pathogenesis, and establish a new theoretical basis for diagnosing, treating, and preventing polycystic ovary syndrome. METHODS Relevant scientific literature was covered from 1992 to 2020 by searching the PubMed database with search terms: insulin/insulin resistance, polycystic ovary syndrome, microRNAs, and metabolic diseases. References of relevant studies were cross-checked. RESULTS The related miRNAs (including differentially expressed miRNAs) and their roles in pathogenesis, and possible therapeutic targets and pathways, are discussed, highlighting controversies and offering thoughts for future directions. CONCLUSION We found abundant evidence on the role of differentially expressed miRNAs with its related phenotypes in PCOS. Considering the essential role of insulin resistance in the pathogenesis of PCOS, the alterations of associated miRNAs need more research attention. We speculate that race/ethnicity or PCOS phenotype and differences in methodological differences might lead to inconsistencies in research findings; thus, several miRNA profiles need to be investigated further to qualify for the potential therapeutic targets for PCOS-IR.

Abstract
OBJECTIVE To evaluate whether irregular or long menstrual cycles throughout the life course are associated with all cause and cause specific premature mortality (age <70 years). DESIGN Prospective cohort study. SETTING Nurses' Health Study II (1993-2017). PARTICIPANTS 79 505 premenopausal women without a history of cardiovascular disease, cancer, or diabetes and who reported the usual length and regularity of their menstrual cycles at ages 14-17 years, 18-22 years, and 29-46 years. MAIN OUTCOME MEASURES Hazard ratios and 95% confidence intervals for all cause and cause specific premature mortality (death before age 70 years) were estimated from multivariable Cox proportional hazards models. RESULTS During 24 years of follow-up, 1975 premature deaths were documented, including 894 from cancer and 172 from cardiovascular disease. Women who reported always having irregular menstrual cycles experienced higher mortality rates during follow-up than women who reported very regular cycles in the same age ranges. The crude mortality rate per 1000 person years of follow-up for women reporting very regular cycles and women reporting always irregular cycles were 1.05 and 1.23 for cycle characteristics at ages 14-17 years, 1.00 and 1.37 for cycle characteristics at ages 18-22 years, and 1.00 and 1.68 for cycle characteristics at ages 29-46 years. The corresponding multivariable adjusted hazard ratios for premature death during follow-up were 1.18 (95% confidence interval 1.02 to 1.37), 1.37 (1.09 to 1.73), and 1.39 (1.14 to 1.70), respectively. Similarly, women who reported that their usual cycle length was 40 days or more at ages 18-22 years and 29-46 years were more likely to die prematurely than women who reported a usual cycle length of 26-31 days in the same age ranges (1.34, 1.06 to 1.69; and 1.40, 1.17 to 1.68, respectively). These relations were strongest for deaths related to cardiovascular disease. The higher mortality associated with long and irregular menstrual cycles was slightly stronger among current smokers. CONCLUSIONS Irregular and long menstrual cycles in adolescence and adulthood are associated with a greater risk of premature mortality (age <70 years). This relation is slightly stronger among women who smoke.

Abstract
Dietary intake potentially modifies the prevalence or severity of asthma. The prevalence of asthma is higher in women with polycystic ovary syndrome (PCOS); it is not known if diet confounds or modifies the association between asthma and PCOS. The aims of this study were: (i) To determine if the association of PCOS and asthma is independent of dietary pattern and (ii) to determine if dietary pattern modifies the association between PCOS and asthma. Women in this study were from the Australian Longitudinal Study on Women's Health (ALSWH) cohort born between 1973 to 1978 and aged 18 to 23 years (n = 7382). Logistic regression was used to assess the association between PCOS and asthma, adjusting for the following: (i) Potential confounders identified a priori and (ii) dietary patterns (z-score) identified by principle component analysis. In the adjusted analysis, women with PCOS were more likely to have asthma than the women without PCOS (OR 1.35 and 95% CI, 1.02 and 1.78). This relationship was not altered by further adjustment for dietary patterns (non-core food, meats and takeaway, or Mediterranean-style pattern). In the interaction analysis, only the women consuming less than the median intake of non-core foods (i.e., lower intake of discretionary or unhealthy foods) and with PCOS were more likely to have asthma (OR 1.91 and 95% CI, 1.29 and 2.82). Dietary intake did not confound the relationship between PCOS and asthma. Other mechanistic pathways are likely responsible for the asthma and PCOS association, and further studies assessing factors such as oral contraceptive use and sex steroid hormones warrant investigation.

Abstract
Induction of heat shock protein expression and the heat shock (stress) response are seen in exercise. This exercise-induced response is thought protective against cellular stress through the expression of heat shock proteins. The highly inducible heat shock protein 72 (HSP72) has been shown to be expressed in a number of stress-related conditions, but not investigated in women with polycystic ovary syndrome (PCOS). Twenty-one women (10 controls, 11 with PCOS) concluded an 8-week supervised, moderate-intensity exercise programme. Monocytes and lymphocytes were analysed by flow cytometry for HSP72 expression from blood samples prior to, mid-way and at the completion of the programme. The monocyte HSP72 expression showed an increase from baseline values through mid-way (p = 0.025), and at the completion of the programme (p = 0.011) only in the control group, the PCOS group showed no significant change. This pattern was similar for lymphocyte HSP72 expression where a significant increase was found at the completion of the programme (p = 0.01) only in the control group. The magnitude of increased HSP72 expression following completion of the programme was linked to baseline values only in the control group. In conclusion, increased HSP72 expression to exercise over an 8-week period was seen in control but not in PCOS women, suggesting that there is an impairment of HSP72 expression in response to exercise in these women.

Abstract
Introduction: Polycystic ovary syndrome (PCOS) is a common endocrine disorder with heterogeneous clinical manifestations. Current evidence suggests that women with PCOS exhibit an unfavorable metabolic profile which may pose them at increased risk for cardiovascular events later in life.Areas covered: Herein, we present a review of the existing literature relating to PCOS and long-term cardiovascular (CV) health risks in women after menopause. We performed an electronic-based search with the use of PubMed from 1990 to August 2019 and systematically reviewed studies assessing CV events in women with PCOS. We aimed to outline the gaps in the current evidence and suggest areas for future research.Expert opinion: Although there is a clear association between PCOS and cardiometabolic dysfunction, data on actual cardiovascular disease (CVD) events are conflicting. Additional large, prospective cohort studies of well-phenotyped women with PCOS and long-term follow-up into the late menopause are needed to elucidate the true CVD risk in this population.

Abstract
Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder characterized by theca cell hyperplasia and excessive androgen production. An increasing body of evidence has pointed to a close association between PCOS and low-grade chronic systemic inflammation. However, the mechanistic basis for this linkage is unknown. Therefore, we evaluated the effects of the inflammatory agents lipopolysaccharide (LPS) and IL-1β on rat theca-interstitial cells (TICs). We found that incubation with either LPS or IL-1β elicited a dose-dependent increase in both TIC viability and androgen production. Using RNA sequencing analysis, we found that both of these inflammatory agents also triggered profound and widespread shifts in gene expression. Using a stringent statistical cutoff, LPS and IL-1β elicited differential expression of 5201 and 5953 genes, respectively. Among the genes upregulated by both LPS and IL-1β were key regulatory genes involved in the cholesterol and androgen biosynthesis pathways, including Cyp17a1, Cyp11a1, Hsd3b, and Hmgcr. This provides a molecular explanation for the mechanism of action of inflammatory agents leading to increased androgen production. Gene ontology and pathway analysis revealed that both LPS and IL-1β regulated genes highly enriched for many common functions, including the immune response and apoptosis. However, a large number of genes (n = 2222) were also uniquely regulated by LPS and IL-1β, indicating that these inflammatory mediators have substantial differences in their mechanism of action. Together, these findings highlight the potential molecular mechanisms through which chronic low-grade inflammation contributes to the pathogenesis of androgen excess in PCOS.

Abstract
PROBLEM Polycystic ovary syndrome (PCOS) is associated with endoplasmic reticulum (ER) stress and pro-inflammatory condition. The aim of the present study was to evaluate the effect of resveratrol treatment on pro-inflammatory and ER stress markers in patients with PCOS. METHOD OF STUDY Cumulus cells were obtained from 40 patients with PCOS who were divided into two groups: placebo and resveratrol treatment (receiving 800 mg/d for 40 days) groups. Blood samples were obtained from all patients before and after the procedure to evaluate interleukin (IL)-6, IL-1β, IL-18, TNF-α, NF-κB, and C-reactive protein (CRP). Total RNA was extracted from cumulus cells, and cDNA was synthesized by reverse transcription. Expressions of five genes in ER stress response pathway (ATF4, ATF6, CHOP, GRP78, and XBP1s) were assessed with quantitative real-time PCR. Statistical analysis was performed with Student's t test. RESULTS After treatment with resveratrol, it was found that serum levels of IL-6, IL-1β, TNF-α, IL-18, NF-κB, and CRP decreased in the treatment group. In addition, gene expression results showed that the expression levels of ATF4 (P < .05) and ATF6 (P < .001) significantly increased in the resveratrol treatment group, while the expression levels of CHOP, GRP78, and XBP1 (P < .001 for all) significantly decreased. CONCLUSION Results demonstrated that resveratrol has anti-inflammatory effects through the suppression of NF-κB and NF-κB-regulated gene products. On the other hand, resveratrol can modulate ER stress in granulosa cells (GCs) by altering the expression of genes involved in unfolding protein response (UPR) process. Our findings suggest that ER stress is a potential therapeutic target for patients with PCOS.

Metabolic Cytokines at Fasting and During Macronutrient Challenges: Influence of Obesity, Female Androgen Excess and Sex. Nutrients 2019; 11:nu11112566.

Abstract
Scope: Cytokines have pleiotropic functions within the organism and their levels may be influenced by obesity, visceral adiposity and sex hormones. Diet composition may also affect their systemic concentrations during fasting and in the postprandial period. Hence, we studied the influence of sex steroids and obesity on the circulating levels of a panel of metabolic cytokines in the fasting state and after single macronutrient challenges. Methods: On alternate days we submitted 17 women with polycystic ovary syndrome (PCOS) (9 non-obese, 8 obese), 17 non-hyperandrogenic control women (9 non-obese, 8 obese) and 19 control men (10 non-obese, 9 obese) to isocaloric oral glucose, lipid and protein loads. Serum levels of omentin-1, vaspin, lipocalin-2, adipsin, PAI-1, chemerin, FGF-21 and FGF-23 were determined by Luminex multiplex technology. Results: During fasting, obese patients presented higher levels of PAI-1, chemerin and adipsin but decreased FGF-23 and omentin-1 compared with non-obese subjects. Vaspin showed sexual dimorphism with lower levels in men than women with PCOS and female controls. Following macronutrient ingestion, most metabolic cytokines presented a similar physiological response consisting of a decrease in circulating concentrations, which was inversely associated with the fasting levels of these molecules. Protein intake caused the major postprandial decrease whereas glucose did not significantly reduce PAI-1, FGF-23 and vaspin, and even increased FGF-21. Regardless of the macronutrient administered, vaspin levels showed a larger reduction in non-obese individuals while the decrease in PAI-1 was particularly noticeable in the obese subgroup. The postprandial reductions of omentin-1 and FGF-23 after glucose and protein loads were influenced by obesity. No major differences were found between patients with PCOS and male and female controls. Conclusions: Obesity, but not PCOS or sex, markedly influences metabolic cytokine levels at fasting and after macronutrient ingestion. The observed postprandial decrease in their circulating concentrations might represent a physiological compensatory mechanism against food-induced inflammation and oxidative stress. This mechanism is altered by obesity and is differently modulated by macronutrients, suggesting a larger contribution of glucose to stressful postprandial responses.

Abstract
Polycystic ovary syndrome (PCOS) is a multifactorial disease, which is resulted from the three common features, hyperandrogenism (HA), ovulatory dysfunction (OD), and polycystic ovarian morphology (PCOM). The environmental inducers (like diet, lifestyle, chemicals, drugs, and ageing) and cardiometabolic risk factors (such as insulin resistance, metabolic syndrome, and obesity) are involved in pathogenesis of PCOS. The growing body of evidence has been shown that there exist endothelial cell dysfunction (ECD) in women with PCOS independent of age, weight and metabolic abnormalities. It has been shown that a broad spectrum of cardiovascular risk markers are involved in ECD- induced cardiovascular disease. It is well described that there are no worldwide treatments for PCOS and all of pharmacological treatments are off -label without any approval. MNAM is one of potential therapeutic factor, which produced by nicotinamide N-methyltransferase (NNMT) via consumption of S-adenosyl methionine (SAM) and nicotinamide. Only one study has shown higher expression of its producer enzyme, NNMT, in the cumulus cells of women with PCOS. Therefore, we reviewed beneficial effects of MNAM on modulation of cardiometabolic risk factors, which are associated to PCOS and try to describe possible mode of action of MNAM in the regulation of these markers.

Abstract
Although polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders affecting women, its etiology is not entirely understood. Clinical symptoms of PCOS include acne, amenorrhea or oligomenorrhea, hirsutism, infertility, and mood disorders, which tend to be the primary focus of clinical management. However, the impact of PCOS on future cardiovascular disease (CVD) risk should not be overlooked, and opportunities to implement CVD prevention strategies in these women should be given high priority. The pathogenesis of PCOS commonly involves insulin resistance which leads to several cardiometabolic abnormalities (e.g., dyslipidemia, hypertension, glucose intolerance, diabetes, and metabolic syndrome), thereby putting women at an increased risk for CVD. Prior studies have found that subclinical CVD markers such as coronary artery calcium scores, C-reactive protein, carotid intima-media thickness, and endothelial dysfunction are more likely to be increased in women with PCOS. While the associations between PCOS and cardiometabolic abnormalities have been well established, whether PCOS is associated with subclinical and clinical CVD, independently of these CVD risk factors, is not entirely clear. Lifestyle interventions and weight management may mitigate some of these future CVD risks and should be encouraged. This review summarizes the literature on PCOS and CVD risk factors and provides recommendations that would aid clinicians in the management of these risk factors.

Abstract
BACKGROUND The risk of venous thromboembolism (VTE) in young women can predominantly be attributed to exogenous hormone use. The influence of (abnormalities in) endogenous sex hormones, as in polycystic ovary syndrome (PCOS) or primary ovarian insufficiency (POI), on VTE risk is uncertain. OBJECTIVES Th assess the association between endogenous sex hormone levels and VTE risk. METHODS Women aged ≤45 years from the MEGA case-control study who provided a blood sample in the absence of exogenous hormone exposure or pregnancy were included. Sex hormone-binding globulin (SHBG), estradiol, follicle-stimulating hormone (FSH) and testosterone were measured. The free androgen index (FAI) and estradiol to testosterone ratio (E:T) were calculated. VTE risk was assessed according to quartiles (Qs) of levels and clinical cut-offs as proxies for PCOS (FAI > 4.5) and POI (FSH > 40 U/L). Logistic regression models were used to estimate adjusted odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS Six hundred and sixty-five women (369 cases; 296 controls) were eligible for the analyses. Testosterone and FSH levels, E:T and POI (FSH > 40 U/L vs FSH ≤ 40 U/L) were not associated with VTE risk. For estradiol, VTE risk was increased with levels in Q4 vs Q1 (OR 1.6; 95% CI 1.0-2.5). There was a dose-response relationship between SHBG levels and VTE risk, with the highest OR at Q4 vs Q1: 2.0 (95% CI 1.2-3.3). FAI > 4.5 (PCOS proxy) vs FAI ≤ 4.5 was associated with increased VTE risk (OR 3.3; 95% CI 0.9-11.8). CONCLUSIONS Estradiol, SHBG and FAI were associated with VTE risk, suggesting a role for endogenous sex hormones in the pathophysiology of VTE in young women.

[PMID: 31200968 DOI: 10.1016/j.fertnstert.2019.04.024] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2018] [Revised: 03/27/2019] [Accepted: 04/15/2019] [Indexed: 10/26/2022]
Abstract
OBJECTIVE To determine the association between serum androgens measured by high-resolution liquid chromatography-mass spectrometry and coronary artery calcium (CAC) scores. DESIGN Cross-sectional study. SETTING Academic institution. PATIENT(S) A total of 239 women, aged 40-75 years, with CAC testing and complete cardiovascular disease risk evaluation. Total T, DHEA, and androstenedione were measured using high-resolution liquid chromatography-mass spectrometry, whereas E2 and sex hormone-binding globulin were measured using commercial assays. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Independent associations between CAC scores and sex steroids. RESULT(S) Overall, 164 subjects had a CAC score < 10, 48 had a CAC score between 10 and 100, and 27 had a score > 100. There were no differences in sex hormone levels between women with CAC scores > 10 vs. CAC scores ≤ 10. In multivariable models adjusting for age, body mass index, and low-density lipoprotein cholesterol, a higher T/E2 ratio was associated with an elevated CAC score, with an unadjusted odds ratio associated with 1-SD change in log-transformed T/E2 of 1.38 (95% confidence interval 1.01-1.89) and adjusted OR 1.02 (95% confidence interval 1.002-1.04). Total T, DHEA, androstenedione, sex hormone-binding globulin, and E2 levels were not associated with increased CAC. CONCLUSION(S) In the general population, there are mixed reports regarding the relationship between serum androgens and risk factors for cardiovascular disease, and limited information on the relationship between androgens and subclinical atherosclerosis. Our study shows that increased androgens relative to estrogens may have a weak but independent association with subclinical atherosclerosis, as measured by CAC scores.

Abstract
RESEARCH QUESTION What is the association between hyperhomocysteinaemia (HHCY), metabolic syndrome, and reproductive outcomes among women with polycystic ovary syndrome (PCOS). DESIGN A secondary analysis of PCOSAct with 21 sites in China. A total of 1000 women with PCOS were enrolled; 936 women with baseline homocysteine (HCY) were analysed. RESULTS Higher HCY was associated with higher body mass index, free testosterone and lower FSH, fasting glucose (P < 0.001; P < 0.001; P = 0.005; P < 0.001) and ovulation rate among all participants (OR 0.59, 95% CI 0.41 to 0.86; OR 0.57, 95% CI 0.39 to 0.83 tertiles 2 and 3 versus tertile 1, respectively). The HHCY group had lower oestradiol and higher free testosterone (P = 0.04; P < 0.001) than the controls. In the metabolic syndrome group, LH, LH-FSH ratio and sex hormone-binding globulin were lowest in the metabolic syndrome group (all P < 0.001). In the HHCY group, ovulation rate decreased and the second or third trimester pregnancy loss rate increased compared with controls (OR 1.678, 95% CI 1.04 to 2.70; OR 0.03, 95% CI 0.00 to 0.42) with treatment adjustment. Compared with the controls, ovulation, conception, pregnancy, second or third trimester pregnancy loss and live birth rates were statistically lower in the metabolic syndrome group after adjusting treatment (OR 1.76, 95% CI 1.15 to 2.70; OR 1.75, 95% CI 1.15 to 2.65; OR 2.09, 95% CI 1.27 to 3.44; OR 0.02, 95% CI 0.00 to 0.33; OR 2.42 95% CI 1.42 to 4.10), and pregnancy, pregnancy loss and live birth rates remained significantly different after adjusting for treatment and sex-hormone factors (OR 1.77, 95% CI 1.05 to 2.99; OR 0.14, 95% CI 0.02 to 0.82; OR 2.02, 95% CI 1.16 to 3.50). CONCLUSIONS In women with PCOS, HHCY contributes to increased pregnancy loss and reduced ovulation, and metabolic syndrome was related to defects in ovulation, conception, pregnancy, pregnancy loss and live birth, indicating that the two conditions lead to defects at various reproductive stages.

Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is a common endocrine disorder affecting up to 18% women of reproductive age. It is associated with a range of metabolic, reproductive, and psychological features. Current evidence indicates a role of PCOS in the development of metabolic and increased cardiovascular risk factors (CVRF) with implications for compromised cardiovascular endpoint disease, which may have a considerable impact on health and health care costs. AREAS COVERED Existing studies examining long-term cardiometabolic health in PCOS are heterogeneous with inconsistent findings. In the current review, we aim to explore and critically review retrospective, prospective, meta-analysis and review articles relating to PCOS on cardiometabolic risk factors and clinical consequences to summarize the evidence, note evidence gaps, and suggest implications for future research. EXPERT COMMENTARY Although there is an established association between PCOS and metabolic health, implications on cardiac health are more uncertain with associations observed for CVRF and subclinical disease, yet limited and conflicting data on actual cardiovascular endpoints. There is a lack of population-based long-term studies examining cardiometabolic morbidity and mortality in PCOS with a need for further research to progress toward a better understanding of the long-term cardiometabolic impacts in women with PCOS.

Front Endocrinol (Lausanne) 2019; 10:659. [PMID: 31608014 PMCID: PMC6773810 DOI: 10.3389/fendo.2019.00659] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2019] [Accepted: 09/11/2019] [Indexed: 12/19/2022] Open
Abstract
Objective: To correlate features of metabolic syndrome with creatine kinase (CK) in women with and without polycystic ovary syndrome (PCOS). Design: Comparative cross-sectional analysis. Methods: Demographic and metabolic data from Qatari women aged 18-40 years from the Qatar Biobank (97 diagnosed with PCOS, 563 controls). The primary outcome was the association between plasma CK and features of metabolic syndrome. Results: CK increased when the waist circumference was >80 cm (p < 0.015) and when associated with 2 or more features of the metabolic syndrome (p < 0.01). CK correlated with BMI (p < 0.003) but not with waist/hip ratio. Overall, CK did not differ between PCOS and controls, rising equally in both as body mass index (BMI) increased. C reactive protein (CRP) was higher in obese PCOS (P < 0.05) compared to controls, but did not correlate with CK (p > 0.05). Conclusion: CK was associated with an increase in BMI, waist circumference >80 cm and 2 or more features of the metabolic syndrome, in accord with the central role of type II skeletal muscle fibers in energy metabolism and obesity. CK was, however, independent of the PCOS phenotype.
