Eur J Obstet Gynecol Reprod Biol 2024; 297:24-29. [PMID: 38555852 DOI: 10.1016/j.ejogrb.2024.03.034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 03/08/2024] [Accepted: 03/26/2024] [Indexed: 04/02/2024]
Abstract
OBJECTIVE To investigate the relationship between body composition and serum visfatin and apelin levels in patients with polycystic ovary syndrome (PCOS). METHODS In this prospective observational study, the differences in body composition, levels of gonadal hormone concentrations, glucose metabolism, apelin, and visfatin were compared between PCOS patients and the control group. PCOS patients were further divided into different subgroups according to different obesity criteria and the differences between serum visfatin and apelin levels in different subgroups were compared. Finally, the correlation of serum visfatin levels and apelin levels with body composition, and metabolism-related indicators in PCOS patients was explored. RESULTS A total collected 178 cases of PCOS patients and 172 cases of healthy women (control group) between 2020 July and 2021 November. In PCOS patients, their weight, Body Mass Index (BMI), Waist Hip Rate (WHR), Fat-Free Mass Index (FFMI), Percent Body Fat (PBF), Fat mass index (FMI), PBF of Arm, PBF of Leg, PBF of the Trunk, Visceral Fat Level (VFL), fasting insulin (FINS), Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) and Luteinizing hormone (LH) were significantly higher than in the control group (all P < 0.001), Percent Skeletal Muscle (PSM), PSM of Leg, and PSM of the Trunk were significantly decreased than in the control group (all P < 0.001). The PCOS patients had significantly higher serum visfatin levels and apelin levels compared with the control group (all P < 0.001). In PBF > 35 % PCOS patients, the apelin and visfatin levels were significantly higher than the PBF ≤ 35 % PCOS patients. In WHR ≥ 0.85 and BMI ≥ 24 kg/m2 PCOS patients, the visfatin levels were significantly higher than the WHR < 0.85 and BMI < 24 kg/m2 PCOS patients. Serum apelin and visfatin positively correlated with BMI level, WHR, FFMI, PBF, FMI, PBF of arms, PBF of legs, PBF of the trunk, VFL, FBG, HOMA-IR index and negatively correlated with PSM, PSM of legs, and PSM of the trunk (all P < 0.001). CONCLUSIONS Compared with healthy women, Patients with PCOS have an increased fat content in various parts of the body, reduced skeletal muscle content, and are often complicated by metabolic abnormalities. Serum visfatin and apelin correlated not only with obesity, fat mass, and fat distribution but also with muscle mass and distribution. It may be possible to reduce the long-term risk of metabolic disease in PCOS through the monitoring and management of the body composition in PCOS patients or to reflect the therapeutic effect of PCOS.

Cai J, Yue J, Lu N, Li S, Zheng J, Huang R, Jiang Y, Shan C, Liu W, Ma J, Wang L. Association of Fat Mass and Skeletal Muscle Mass with Cardiometabolic Risk Varied in Distinct PCOS Subtypes: A Propensity Score-Matched Case-Control Study. J Clin Med 2024; 13:483. [PMID: 38256617 PMCID: PMC10817046 DOI: 10.3390/jcm13020483] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 01/08/2024] [Accepted: 01/12/2024] [Indexed: 01/24/2024] Open
Abstract
(1) Background: polycystic ovarian syndrome (PCOS) is a heterogeneous syndrome with a constellation of cardiometabolic risk factors. We aimed to investigate if the association of body fat mass (BFM) and skeletal muscle mass (SMM) with cardiometabolic risk differed in PCOS subtypes. (2) Methods: 401 participants (245 PCOS and 156 controls) were assessed for anthropometric measurements, glucose-lipid profiles, reproductive hormones and body composition with propensity score-matched (PSM) analysis. The association of the cardiometabolic risk score (z score, calculated based on levels of obesity and gluco-lipid measurements) with BFM (estimated by trunk BFM/Height2) and SMM (estimated by SMM/Height2) was calculated. (3) Results: Trunk BFM/Height2 and SMM/Height2 were both positively associated with cardiometabolic risk in PCOS (trunk BFM/Height2, OR 2.33, 95% CI 1.49-3.65; SMM/Height2, OR 2.05, 95% CI 1.12-3.76). SMM/Height2 associated with increased cardiometabolic risk in obese PCOS (BMI ≥ 28 kg/m2, OR 2.27, 95% CI 1.15-4.47). For those with lower BMI (<28 kg/m2), trunk BFM/Height2 showed a higher OR in both groups (PCOS, OR 2.12, 95% CI 1.06-4.24; control 2.04, 95% CI 1.04-4.02). Moreover, distinct associations among BMI-stratified groups were validated in hierarchical clustering identifying metabolic and reproductive clusters. (4) Conclusions: BFM and SMM are synergistically associated with higher cardiometabolic risk in PCOS women. Although BFM contributes to increased cardiometabolic risk, SMM also plays a primary role in obese PCOS. Our results highlight the importance of body composition in the management of PCOS.

Abstract
OBJECTIVE Though recent studies have pointed out different manifestations between obese and nonobese patients with polycystic ovarian syndrome (PCOS), there is no clear evidence to confirm this viewpoint. Therefore, the metabolic characteristics of obese and nonobese patients with PCOS were systematically compared through meta-analysis in this study. METHODS Data were searched from PubMed, Web of Science, Embase, Cochrane Library, CNKI, and Wanfang databases. Articles on obese and nonobese patients with PCOS published from database inception to January 2022 were included. Meta-analysis was performed using Stata 16.0 statistical software. RESULTS A total of 739 articles were initially retrieved, and ultimately 14 studies were involved in the meta-analysis. Specifically, there were 801 patients in the observation group (obese patients with PCOS) and 925 patients in the control group (nonobese patients with PCOS). Compared with the control group, the observation group had significantly lower levels of sex hormone-binding globulin (SHBG), high-density lipoprotein (HDL), luteinizing hormone (LH), follicle-stimulating hormone (FSH), and higher levels of total cholesterol (TC), triglyceride (TG), and low-density lipoprotein (LDL). Nevertheless, there were no significant differences between the two groups in systolic blood pressure (SBP), diastolic blood pressure (DBP), glucose, and testosterone. CONCLUSION Compared with nonobese patients with PCOS, obese patients with PCOS have worse blood lipid parameters and lower levels of LH and FSH. Also, there are significant differences in metabolic characteristics between the two groups of patients. Most importantly, our findings provide guidance for the clinical diagnosis and treatment of PCOS.

Abstract
BACKGROUND Polycystic ovarian syndrome (PCOS) is a multifactorial condition with metabolic-related complications, such as diabetic nephropathy and chronic renal disorder, which are the leading cause of renal transplant globally. Protective effects of histone deacetylase (HDAC) inhibitors (HDACi) have been documented in metabolic-linked pathologies. Nonetheless, the current study investigated the restorative role of HDACi, butyrate in experimental PCOS-induced renal disorder. MATERIALS AND METHODS Female Wistar rats (8-week-old) were divided into groups; control, butyrate-treated, letrozole and letrozole + butyrate-treated groups. To induce PCOS, 1 mg/kg of letrozole was given (oral gavage) for 21 days. After confirmation of PCOS, 200 mg/kg of butyrate (oral gavage) was administered for 6 weeks. RESULTS Rats with PCOS revealed disruption in glucose homeostasis (hyperinsulinemia and impaired glucose tolerance and insulin resistance) and presented with the phenotypes of PCOS (hyperandrogenism, multiple ovarian cysts and elevated LH/FSH ratio). Increased plasma and renal triglycerides and inflammatory (TNF-α/SDF-1/NF-κB) markers were observed with elevated levels of TGFβ-1, renal lipid peroxidation and redox imbalance (GGT, GSH, HIF-1α). Interestingly, animals with PCOS reported increased body weight as well as renal mass. Whereas, heightened levels of plasma urea, creatinine and creatine kinase indicating renal dysfunction, characterized by renal apoptosis (Caspase-6) and increased HDAC2 levels. Notwithstanding, administration of butyrate averted the alterations. CONCLUSION The present investigation demonstrates that PCOS declines renal function, which is accompanied by renal inflammation, apoptosis and fibrosis. The study further suggests that butyrate, an HDAC2i restores renal function by suppressing renal SDF-1 with subsequent attenuation of renal inflammation, apoptosis and fibrosis.

Abstract
Introduction The aim of the study was to identify available polycystic ovary syndrome (PCOS) models of care (MoCs) and describe their characteristics and alignment with the international PCOS guideline. Methods Ovid MEDLINE, All EBM, PsycINFO, Embase, and CINAHL were searched from inception until 11 July 2022. Any study with a description of a PCOS MoC was included. Non-evidence-based guidelines, abstracts, study protocols, and clinical trial registrations were excluded. We also excluded MoCs delivered in research settings to minimize care bias. Meta-analysis was not performed due to heterogeneity across MoCs. We describe and evaluate each MoC based on the recommendations made by the international evidence-based guideline for assessing and managing PCOS. Results Of 3,671 articles, six articles describing five MoCs were included in our systematic review. All MoCs described a multidisciplinary approach, including an endocrinologist, dietitian, gynecologist, psychologist, dermatologist, etc. Three MoCs described all aspects of PCOS care aligned with the international guideline recommendations. These include providing education on long-term risks, lifestyle interventions, screening and management of emotional well-being, cardiometabolic diseases, and the dermatological and reproductive elements of PCOS. Three MoCs evaluated patients' and healthcare professionals' satisfaction, with generally positive findings. Only one MoC explored the impact of their service on patients' health outcomes and showed improvement in BMI. Conclusion There is limited literature describing PCOS MoCs in routine practice. Future research should explore developing cost-effective co-created multidisciplinary PCOS MoCs globally. This may be facilitated by the exchange of best practices between institutions with an established MoC and those who are interested in setting one up.

[PMID: 37547087 PMCID: PMC10404011 DOI: 10.4103/jhrs.jhrs_60_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 06/16/2023] [Accepted: 06/19/2023] [Indexed: 08/08/2023] Open
Abstract
Background Polycystic ovary syndrome (PCOS) is a heterogeneous disorder with a spectrum of presentation. Studies have reported considerably different rates in terms of the incidence of polycystic ovary morphology (PCOM) in patients with PCOS with inconsistent results regarding the effects of PCOM in them. Aims The aim of this study was to determine the differences in clinical presentation, metabolic profile, hormonal parameters and inflammatory markers in PCOS women with and without PCOM on ultrasonography (USG). Settings and Design A total of 70 PCOS women were recruited. To analyse the differences between various parameters, the patients were divided into two groups based on the presence or absence of PCOM on USG of the pelvis as per the Rotterdam criteria. Materials and Methods A total of 37 patients had PCOM as per the diagnostic criteria for PCOS (Group 1), while 33 patients did not have PCOM on USG and were designated as Group 2. All participants underwent a detailed clinical evaluation and biochemical investigations, including high-sensitivity C-reactive protein, serum adiponectin, luteinising hormone, follicle-stimulating hormone, total testosterone and serum anti-Mullerian hormone. The homeostasis model assessment of IR (HOMA-IR) was calculated using standard equations. Statistical Analysis Used The mean and Standard deviation were computed for all continuous variables. Frequencies and proportions were calculated for categorical variables. Comparisons of the mean scores between the study groups were assessed using the Unpaired Student's t-test. The mean score of the subgroups was also compared using the unpaired Student's t-test. P < 0.05 was considered significant for all statistical inferences. Results The mean LDL and mean triglyceride were higher in Group 2, which was statistically significant (P = 0.004 and P ≤ 0.001, respectively). The mean hs-CRP was found to be higher in Group 2, which was statistically significant (P = 0.005). The mean AMH was higher in Group 1, which was statistically significant (P = 0.002). Group 1 had higher adiponectin levels, which was statistically significant (P = 0.04). Conclusion The above findings suggest that patients without diagnostic PCO morphology have a worse metabolic profile compared to those with PCO morphology on USG. Obese patients without PCO morphology probably have a higher cardiovascular risk compared to obese patients with PCO morphology.

Abstract
Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders, affecting 5%-10% of women of reproductive age. The importance of this syndrome lies in the magnitude of associated comorbidities: infertility, metabolic dysfunction, cardiovascular disease (CVD), plus psychological and oncological complications. Insulin resistance (IR) is a prominent feature of PCOS with a prevalence of 35%-80%. Without adequate management, IR with compensatory hyperinsulinemia contributes directly to reproductive dysfunction in women with PCOS. Furthermore, epidemiological data shows compelling evidence that PCOS is associated with an increased risk of impaired glucose tolerance, gestational diabetes mellitus and type 2 diabetes. In addition, metabolic dysfunction leads to a risk for CVD that increases with aging in women with PCOS. Indeed, the severity of IR in women with PCOS is associated with the amount of abdominal obesity, even in lean women with PCOS. Given these drastic implications, it is important to diagnose and treat insulin resistance as early as possible. Many markers have been proposed. However, quantitative assessment of IR in clinical practice remains a major challenge. The gold standard method for assessing insulin sensitivity is the hyperinsulinemic euglycemic glucose clamp. However, it is not used routinely because of the complexity of its procedure. Consequently, there has been an urgent need for surrogate markers of IR that are more applicable in large population-based epidemiological investigations. Despite this, many of them are either difficult to apply in routine clinical practice or useless for women with PCOS. Considering this difficulty, there is still a need for an accurate marker for easy, early detection and assessment of IR in women with PCOS. This review highlights markers of IR already used in women with PCOS, including new markers recently reported in literature, and it establishes a new classification for these markers.

Turmeric extract alleviates endocrine-metabolic disturbances in letrozole-induced PCOS by increasing adiponectin circulation: A comparison with Metformin. Metabol Open 2022; 13:100160. [PMID: 35005596 PMCID: PMC8717583 DOI: 10.1016/j.metop.2021.100160] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2021] [Revised: 12/16/2021] [Accepted: 12/16/2021] [Indexed: 11/25/2022] Open
Abstract
One of the most common causes of female infertility is polycystic ovarian syndrome, which affects 6–21% of the population. Regrettably, the currently available treatments are mostly symptomatic and ineffective. As a result, safer options are needed now more than ever. In a letrozole PCOS albino mouse model, the current study compares the therapeutic advantages of Turmeric extract (Curcuma longa) to metformin. Adiponectin is a circulating protein generated by adipocytes that has been linked to metabolic diseases (MDs) in an inverse relationship. The effects of Turmeric Extract (Curcuma Longa) in contrast to Metformin, as well as the involvement of adiponectin in endocrine-metabolic abnormalities in experimentally induced PCOS mice model, were studied in this study. Letrozole (6 mg/kg) was administered orally (p.o) for 21 days to induce PCOS, followed by a dose of Turmeric Extract (Curcuma longa) (175 mg/kg and p.o) and Metformin (150 mg/kg) for 30 days, both with normal saline water (0.9%) as the carrier. The findings revealed that LET-treated mice displayed PCOS-like characteristics, such as higher LH levels, increased body weight growth, and ovarian morphology with numerous cysts, increase in fasting blood glucose, lipid profile, plasma lipid peroxidation (MDA) and IL-6, as well as a decrease in serum Progesterone, Estrogen, FSH, SOD and GSH levels in the ovary. These changes were linked to lower levels of circulating adiponectin and were reversed when treated Turmeric extract. By altering circulating androgen-adiponectin balance, the data implies that Turmeric extract alleviates endocrine-metabolic abnormalities and inflammation-related comorbidities associated with LET-induced PCOS.

Abstract
OBJECTIVES To investigate the changes in body fat distribution and predicting factors of these changes in polycystic ovary syndrome (PCOS) patients with obesity, after laparoscopic sleeve gastrectomy (LSG). METHODS This study consecutively enrolled 153 patients with obesity aged 18-45 years (83 with PCOS and 70 control patients) who underwent LSG from May 2013 to September 2020 at the Department of Endocrinology, Shanghai Tenth People's Hospital, with a 12-month follow-up. Dual-energy X-ray absorptiometry (DEXA) was used to assess body fat distribution. RESULTS The percentage of fat mass loss in the visceral adipose tissue (VAT) region (55.08%) was more than that in any other body regions at 12 months post-surgery in the PCOS group yet insignificant. Homeostatic model assessment of insulin resistance (HOMA-IR) at baseline and Δ HOMA-IR were only negatively correlated with the variations in VAT mass and volume at 3 months post-surgery in the PCOS group. Logistic regression analysis showed that HOMA-IR <6.65 was an independent predictive factor for the changes in VAT mass and volume at 3 months post-surgery in the PCOS group. CONCLUSIONS In this study, the percentage loss of fat mass was greater in the VAT region than in any other body regions in all patients. The rate of VAT decrease in the PCOS group was higher than that in the control group yet insignificant. Compared with control patients, HOMA-IR at baseline was an independent risk factor for the changes in VAT mass and volume at 3 months post-surgery in patients with PCOS. KEY POINTS • The percentage loss of fat mass was greater in the VAT region than in any other body regions in all patients. • The rate of VAT decrease in the PCOS group was higher than that in the control group yet insignificant. • HOMA-IR at baseline was an independent risk factor for the changes of VAT mass in patients with PCOS.

Abstract
OBJECTIVE To determine if visceral adipose tissue (VAT) area measured through MRI can be used opportunistically to assess the presence of cardiometabolic risk factors and compare its performance to simpler adiposity measures. METHODS A cross-sectional analysis was carried out on a subset of 1683 participants (856 women) from the Adiposity Phenotype Study (mean age=69.2y; range 59.9-77.4). The association of total VAT area (sum of four cross sections, L1-L2, L2-L3, L3-L4, L4-L5) and each location, as well as BMI and body fat % (per SD) with the metabolic syndrome (MetSx) or its components was evaluated through logistic regression analysis. RESULTS Total VAT can be accurately predicted using all sites evaluated (R2 range=0.82-0.96). In men, VAT did not show a superior association to MetSx compared to BMI in men. However, in women, VAT was consistently superior to BMI and body fat % in its association to MetSx, independent of ethnicity [odds ratio for BMI, body fat %and total VAT area=2.25 (95% CI: 1.93-2.62); 1.66 (95% CI: 1.36-2.03); 6.20 (95% CI: 4.69-8.21) respectively in all women]. Ethnic-specific odds ratios to MetSx in women ranged from 5.38 to 8.63 for total VAT area and 2.12-4.08 for BMI. CONCLUSION Total VAT area can be accurately predicted from individual VAT regions in men and women and offers superior association to BMI for MetSx in women but not in men for five ethnicities. Therefore, opportunistic screening for elevated VAT area in women may be warranted across multiple ethnic groups.

Regulation of circulating CTRP-2/CTRP-9 and GDF-8/GDF-15 by intralipids and insulin in healthy control and polycystic ovary syndrome women following chronic exercise training. Lipids Health Dis 2021; 20:34. [PMID: 33874963 PMCID: PMC8054421 DOI: 10.1186/s12944-021-01463-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2020] [Accepted: 04/06/2021] [Indexed: 11/10/2022] Open
Abstract
Background Polycystic ovary syndrome (PCOS) is associated with obesity, diabetes, and insulin resistance. The circulating C1Q/TNF-related proteins (CTRP-2, CTRP-9) and growth differentiation factors (GDF-8, GDF-15) contribute to glucose and lipid homeostasis. The effects of intralipids and insulin infusion on CTRP-2, CTRP-9, GDF-8 and GDF-15 in PCOS and control subjects before and after chronic exercise training were examined. Methods Ten PCOS and nine healthy subjects were studied at baseline status and after moderate-intensity chronic exercise training (1 h exercise, 3 times per week, 8 weeks). All participants were infused with 1.5 mL/min of saline or intralipids (20%) for 5 h, and during the last 2 h of saline or intralipids infusion hyperinsulinemic-euglycemic clamp (HIEC) was performed. CTRP-2, CTRP-9, GDF-8 and GDF-15 levels were measured at 0, 3 and 5 h. Results Intralipids dramatically increased CTRP-2 levels in PCOS (P = 0.02) and control (P = 0.004) subjects, which was not affected by insulin infusion or by exercise. Intralipids alone had no effects on CTRP-9, GDF-8, or GDF-15. Insulin increased the levels of GDF-15 in control subjects (P = 0.05) during the saline study and in PCOS subjects (P = 0.04) during the intralipid infusion. Insulin suppressed CTRP9 levels during the intralipid study in both PCOS (P = 0.04) and control (P = 0.01) subjects. Exercise significantly reduced fasting GDF-8 levels in PCOS (P = 0.03) and control (P = 0.04) subjects; however, intralipids infusion after chronic exercise training increased GDF-8 levels in both PCOS (P = 0.003) and control (P = 0.05) subjects and insulin infusion during intralipid infusion reduced the rise of GDF-8 levels. Conclusion This study showed that exogenous lipids modulate CTRP-2, which might have a physiological role in lipid metabolism. Since chronic exercise training reduced fasting GDF-8 levels; GDF-8 might have a role in humoral adaptation to exercise. GDF-15 and CTRP-9 levels are responsive to insulin, and thus they may play a role in insulin responses.

Abstract
BACKGROUND Women with polycystic ovary syndrome (PCOS) are generally considered to be central obese and at higher risks of metabolic disturbances. Imaging methods are the golden standards for detecting body fat distribution. However, evidence based on magnetic resonance imaging (MRI) and computed tomography (CT) is conflicting. This study systematically reviewed the imaging-based body fat distribution in PCOS patients and quantitatively evaluated the difference in body fat distribution between PCOS and BMI-matched controls. METHODS PUBMED, EMBASE, and Web of Science were searched up to December 2019, and studies quantitatively compared body fat distribution by MRI, CT, ultrasound, or X-ray absorptiometry (DXA) between women with PCOS and their BMI-matched controls were included. Two researchers independently reviewed the articles, extract data and evaluated the study quality based on Newcastle-Ottawa Scale (NOS). RESULTS 47 studies were included in systematic review and 39 were eligible for meta-analysis. Compared to BMI-matched controls, higher accumulations of visceral fat (SMD 0.41; 95%CI: 0.23-0.59), abdominal subcutaneous fat (SMD 0.31; 95%CI: 0.20-0.41), total body fat (SMD 0.19; 95% CI: 0.06-0.32), trunk fat (SMD 0.47; 95% CI: 0.17-0.77), and android fat (SMD 0. 36; 95% CI: 0.06-0.66) were identified in PCOS group. However, no significant difference was identified in all the above outcomes in subgroups only including studies using golden standards MRI or CT to evaluate body fat distribution (SMD 0.19; 95%CI: -0.04-0.41 for visceral fat; SMD 0.15; 95%CI: -0.01-0.31 for abdominal subcutaneous fat). Moreover, meta-regression and subgroup analyses showed that young and non-obese patients were more likely to accumulate android fat. CONCLUSIONS PCOS women seem to have abdominal fat accumulation when compared with BMI-matched controls. However, MRI- and CT- assessed fat distribution was similar between PCOS and controls, suggesting central obesity may be independent of PCOS. These findings will help us reappraise the relationship between PCOS and abnormal fat deposition and develop specialized lifestyle interventions for PCOS patients.

Abstract
Polycystic ovary syndrome (PCOS) has been traditionally perceived as a reproductive disorder due to its most common presentation with menstrual dysfunction and infertility. However, it is now clear that women with PCOS are at increased risk of metabolic dysfunction, from impaired glucose tolerance and type 2 diabetes mellitus to nonalcoholic fatty liver disease and cardiovascular disease. PCOS is characterised by androgen excess, with cross-sectional data showing that hyperandrogenism is directly complicit in the development of metabolic complications. Recent studies have also shown that C11-oxy C19 androgens are emerging to be clinically and biochemically significant in PCOS, thus emphasising the importance of understanding the impact of both classic and C11-oxy C19 androgens on women's health. Here we discuss androgen metabolism in the context of PCOS, and dissect the role played by androgens in the development of metabolic disease through their effects on metabolic target tissues in women.

The resting metabolic rate in women with polycystic ovary syndrome and its relation to the hormonal milieu, insulin metabolism, and body fat distribution: a cohort study. J Endocrinol Invest 2019; 42:1089-1097.

Abstract
PURPOSE To evaluate possible alterations of a major determinant of energy expenditure, the resting metabolic rate (RMR), in women with polycystic ovary syndrome (PCOS) compared with age-BMI similar controls. To assess whether the hormonal milieu, the body fat distribution and the insulin metabolism may affect energy consumption in these patients. METHODS This is a monocentric observational prospective cohort study, including 109 Caucasian PCOS subjects and 31 healthy control women. (Median age PCOS 26.0 ± 9.2 years, controls 25.5 ± 8.5 years; median BMI-body mass index PCOS 26.4 ± 9.4 kg/m2, controls 27.2 ± 12.8 kg/m2). RMR was evaluated by the SenseWear Armband (SWA), a reliable and validated metabolic holter, never previously used in the PCOS population to this purpose. Hormonal assessment, insulin metabolism evaluated by HOMA-IR and OGTT, anthropometric features (BMI and WHR) were also assessed. RESULTS Median RMR resulted similar in PCOS and control women: 1520.0 ± 248.00 kcal/day vs 1464.0 ± 332.70 kcal/day (p = 0.472), even after adjusting for BMI, fat distribution, insulin metabolism parameters. RMR resulted significantly correlated with BMI, WHR, estradiol levels, SHBG, total cholesterol, triglycerides, basal glycaemia, basal insulinemia, AUC insulin 240', and HOMA. In the subgroup of patients with WHR > 0.85, PCOS women showed a significantly lower RMR compared with controls. CONCLUSIONS The higher prevalence of obesity, which negatively influences the reproductive and general health of PCOS women, could be related to factors other than an intrinsic alteration of the RMR. Further studies are needed to clarify the possible role of the visceral fat in modulating the energy balance in PCOS. TRIAL REGISTRATION NUMBER clinicaltrials.gov Identifier NCT03132545.

Abstract
RESEARCH QUESTION The study aimed to evaluate the associations of endocrine and ultrasound characteristics with metabolic syndrome in women with polycystic ovary syndrome (PCOS), and whether these associations were modified by body mass index (BMI). DESIGN The study was a secondary analysis of baseline data from a randomized controlled trial of induction of ovulation in women with PCOS. RESULTS Among 947 Chinese women with PCOS, 153 (16.2%) were diagnosed with metabolic syndrome. The prevalence of metabolic syndrome in women with normal (<24 kg/m2) and high (≥24 kg/m2) BMI was 3.6% and 30.5%, respectively. In all women, a high free androgen index (FAI ≥5%) was positively associated with metabolic syndrome (adjusted odds ratio [OR] 2.06, 95% confidence interval [CI] 1.11-3.82). High FAI was positively associated with metabolic syndrome among women with high BMI (adjusted OR 3.37, 95% CI 1.78-6.37), but the association was not significant in women with normal BMI (adjusted OR 1.27, 95% CI 0.34-4.70). The presence of polycystic ovary morphology was negatively associated with metabolic syndrome (adjusted OR 0.52, 95% CI 0.26-1.03) in all women (normal BMI adjusted OR 0.42, 95% CI 0.11-1.67; high BMI adjusted OR 0.54, 95% CI 0.23-1.28). LH, sex hormone-binding globulin (SHBG) and anti-Müllerian hormone (AMH) were negatively associated with metabolic syndrome. The associations of FAI, SHBG and AMH in relation to metabolic syndrome were significantly modified by BMI. CONCLUSION(S) The associations of endocrine characteristic with metabolic syndrome were modified by BMI in women with PCOS. Women with PCOS and normal BMI did not have an increased risk of metabolic syndrome.

Abstract
OBJECTIVE To explore metabolic disturbances in nonobese women with polycystic ovary syndrome (PCOS) compared with nonobese healthy controls. DESIGN Systematic review and meta-analysis. SETTING Not applicable. PATIENT(S) Nonobese women with PCOS and nonobese healthy controls. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Prevalence of metabolic disturbances including hyperinsulinemia, insulin resistance (IR), impaired fasting glucose (IFG), impaired glucose intolerance (IGT), prediabetes, dyslipidemia, hypercholesterolemia, hypertriglyceridemia, and low high-density lipoprotein (low-HDL), as well as other metabolic outcomes such as type 2 diabetes mellitus (T2DM), hypertension, metabolic syndrome (Mets), myocardial infarction, stroke, cerebrovascular accident, arterial occlusive disease, and coronary heart disease. RESULT(S) Compared to nonobese controls, nonobese women with PCOS showed a higher prevalence of hyperinsulinemia (odds ratio [OR], 36.27; 95% confidence interval [CI] 1.76-747.12), IR (OR, 5.70; 95% CI 1.46-22.32), IGT (OR, 3.42; 95% CI 1.56-7.52), T2DM (OR, 1.47; 95% CI 1.11-1.93), hypertriglyceridemia (OR, 10.46; 95% CI 1.39-78.56), low-HDL (OR, 4.03; 95% CI 1.26-12.95), and Mets (OR, 2.57; 95% CI 1.30-5.07). No significant difference was observed for IFG, pre-DM, dyslipidemia, hypercholesterolemia, and hypertension. In subgroup analysis, Whites exhibited increased risks of IR, IGT, IFG, T2DM, hypertension, and Mets, whereas no significant metabolic change was found in Asians. No study reported specifically an incidence of myocardial infarction, stroke, cerebrovascular accident, arterial occlusive disease, and coronary heart disease in nonobese women with PCOS. CONCLUSION(S) Nonobese women with PCOS also suffer from metabolic disturbances and the risk of long-term metabolic complications. Further efforts should be made to elucidate underlying mechanisms and possible interventions in the early phase.

Abstract
BACKGROUND One of the most frequently encountered endocrinopathy in women of reproductive age is polycystic ovary syndrome (PCOS). Recent studies have reported varied prevalence of metabolic syndrome (MetS) in women with PCOS. The aim of this study is to determine if the women with PCOS are at a higher risk of MetS. METHOD The present systematic review and meta-analysis was conducted according to the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. To collect articles, we searched online databases of PubMed/Medline, Scopus, Web of Science, Science Direct, Embase, CINAHL, Cochrane Library, EBSCO and Google scholar search engine and the reference list of the retrieved articles using MeSH keywords of "metabolic syndrome", "woman" and "polycystic ovary syndrome" without time limit until October 2018. Cochran's Q test and I2 Index were used to evaluate the heterogeneity among studies and the random effects model was used for combining the results. Data analysis was performed in STATA software version 11.1. RESULT Finally, 72 studies involving 10075 PCOS patients with an average age of 26.2 ± 5.01 years were included in the meta-analysis. The heterogeneity rate was high (I2 = 76.5%; p < 0.001) and the pooled estimate of the association between MetS and PCOS was significant (OR = 2.57, 95% CI: 2.18-3.02; P < 0.001). CONCLUSION According to the results, there is higher risk of MetS in women with PCOS. Therefore, diagnosis and treatment of MetS in women with PCOS may have a significant impact on this patients health and reduce the rate of mortality and morbidity.

Ethnicity, obesity and the prevalence of impaired glucose tolerance and type 2 diabetes in PCOS: a systematic review and meta-regression. Hum Reprod Update 2019; 24:455-467. [PMID: 29590375 DOI: 10.1093/humupd/dmy007] [Citation(s) in RCA: 204] [Impact Index Per Article: 40.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2017] [Accepted: 03/12/2018] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Our prior meta-analyses demonstrated an increased prevalence of impaired glucose tolerance (IGT) and type 2 diabetes mellitus (T2DM) with polycystic ovary syndrome (PCOS), but with substantial clinical heterogeneity. OBJECTIVE AND RATIONALE We aimed to update our previous review to quantify the prevalence of IGT and T2DM in PCOS with only quality studies (good and fair quality). We also aimed to examine the contribution of parameters including ethnicity, obesity and method of diagnosing T2DM in explaining the observed heterogeneity in IGT and T2DM prevalence in PCOS. SEARCH METHODS We conducted a literature search (MEDLINE, CINAHL, EMBASE, clinical trial registries and hand-searching) up to June 2016 to identify studies reporting the prevalence of dysglycemia (IGT and T2DM) in women with and without PCOS. We included studies where women with PCOS (defined according to original National Institute of Health) were compared to women without PCOS for the end-points of the prevalence of IGT or T2DM. We excluded case reports, case series, editorials, and narrative reviews. Studies where PCOS was diagnosed by self-report, or where IGT or T2DM were measured by fasting glucose, only were excluded. We assessed the methodological quality of the included studies using a priori criteria based on the Newcastle-Ottawa Scaling (NOS) for non-randomized studies. Data are presented as odds ratio (OR) (95% CI) with random-effects meta-analysis by Mantel-Haenszel methods. We assessed the contribution of demographic and clinical factors to heterogeneity using subgroup and meta-regression analysis. OUTCOMES We reviewed 4530 studies and included 40 eligible studies in the final analysis. On meta-analysis of quality studies, women with PCOS had an increased prevalence of IGT (OR = 3.26, 95% CI: 2.17-4.90) and T2DM (OR = 2.87, 95% CI: 1.44-5.72), which differed by ethnicity (for IGT, Asia: 5-fold, the Americas: 4-fold and Europe: 3-fold), was higher with obesity, and doubled among studies using self-report or administrative data for diagnosing diabetes. The ethnicity-related difference retained its significance for Asia and Europe in BMI-matched subgroups. Clear contributors to heterogeneity did not emerge in meta-regression. WIDER IMPLICATIONS Our findings underscore the importance of PCOS as a cause of dysglycemia with a higher prevalence of IGT and T2DM. They support the relevance of ethnicity and obesity and emphasize the need for accurate diagnostic methods for diabetes. PROSPERO REGISTRATION NUMBER CRD42017056524.

Abstract
Objectives: The objective was to compare body composition, metabolic characteristics, and insulin resistance between obese (body mass index [BMI] ≥25 kg/m2) polycystic ovary syndrome (PCOS) and nonobese PCOS (BMI <25 kg/m2) women and their age- and BMI-matched controls. Materials and Methods: A total of 81 PCOS women (Rotterdam criteria) (obese – 42; nonobese – 39) and 86 controls (obese – 42; nonobese –44) were recruited in this cross-sectional study. All women underwent a detailed assessment of clinical, anthropometric, and metabolic parameters, insulin resistance indices, and body composition measurements with visceral adipose tissue assessment (VAT) (dual-energy X-ray absorptiometry scan). Results: Of PCOS women, 27% (80% – obese PCOS; 20% – nonobese PCOS) were diagnosed with metabolic syndrome (International Diabetes Federation criteria), 35% of PCOS women (46% – obese PCOS; 54% – nonobese PCOS) had impaired glucose tolerance, and 7% of PCOS women (2/3rd – obese PCOS; 1/3rd – nonobese PCOS) had diabetes mellitus. Insulin resistance was seen in about 80% in obese PCOS women and 20% in nonobese PCOS women based on various insulin resistance indices such as fasting insulin (≥12.2 μU/ml), Homeostasis Model Assessment-Insulin Resistance (≥2.5), and Quantitative Insulin Sensitivity Check Index (<0.33). Total body fat, estimated (Est.) VAT, and corrected Est. VAT (corrected for body weight) were significantly increased (P = 0.0001) in both obese and nonobese PCOS women when compared to those of their age- and BMI-matched controls. However, corrected Est. VAT (corrected for body weight) was not significantly different between obese and nonobese PCOS women. Conclusion: Both obese and nonobese PCOS women when compared with their age- and BMI-matched controls were metabolically worse and had more visceral adiposity. Nonobese PCOS poses similar risk as that of obese PCOS in having similar amount of VAT (corrected for body weight).

Abstract
OBJECTIVES This study aimed to investigate the Th1/Th2 cells in peripheral blood of PCOS patients, and assess the potential correlation between Th1/Th2 imbalance and obesity. METHODS Thirty-nine PCOS patients and 23 age-matched controls were enrolled. The PBMCs were obtained before pharmacological intervention in women with or without PCOS. The profiles of Th1 (IFN-γ) and Th2 (IL-4) cytokines of CD3+CD- T lymphocyte subsets were analyzed by flow cytometry. Plasma sex hormones including E2, T, FSH, LH, and FINS, FPG were measured, together with BMI, WC, LH/FSH, E2/T and HOMA-IR index being calculated. Association between Th1/Th2 imbalance and BMI, WC were evaluated. RESULTS The proportion of Th1 cells and Th1/Th2 ratio were significantly higher in PCOS patients than those in controls, accompanied by elevated T, LH, LH/FSH, FINS, HOMA-IR index and reduced E2/T. The Th1/Th2 ratio was increased when BMI and WC were enhanced in PCOS. Moreover, the significant difference of Th1/Th2 ratio was observed between WC subgroups of PCOS. CONCLUSIONS It is concluded that Th1 type immunity is predominant in systemic immunization of PCOS patients. Th1/Th2 immune imbalance is connected with obesity, especially abdominal obesity, and may be one of the underlying mechanism for the pathogenesis of PCOS.

Abstract
Introduction: The objectives of this study were to provide an estimate of the prevalence of metabolic syndrome (MetS ) and its components among women with PCOS; and calculate the odds ratio (OR) for MetS (using different definitions of MetS) in women with PCOS, compared to healthy controls.
Methods: All of the relevant databases were used to search for appropriate articles that were published during the period 2003-2016. We included observational studies (cross-sectional, comparative cross-sectional) among women who met the inclusion criteria. The random-effect models were used to pool the prevalence of MetS and its components among PCOS women. This model was also applied to the pooled OR assessing the association between MetS and PCOS.
Results: The pooled prevalence of MetS among PCOS women was found to be 26.30% (95% CI: 23.68–28.93), but varied from 7.10% (95% CI: 1.64-12.56) to 37.50% (95% CI: 28.84-46.16), depending upon the diagnostic criteria used. Low high-density lipoprotein cholesterol (HDL) - 61.87% (95% CI: 53.31–70.43) and high waist circumference (WC)- 52.23% (95% CI: 43.84–60.61) were the most common components of MetS in PCOS women. Compared to healthy controls, the overall pooled (OR) of MetS in PCOS patients was 2.09 (95% CI: 1.67-2.60), but this ranged from 0.31 (95% CI: 0.13-0.74) to 4.69 (95% CI: 2.09-10.52), depending upon the diagnostic criteria used.
Conclusion: Women with PCOS had a much higher prevalence of MetS than was found among the healthy controls. Furthermore, as low HDL and high WC were the most common components of MetS in PCOS women, these two components specifically need to be addressed in prevention strategies.

Abstract
BACKGROUND AND OBJECTIVE Polycystic ovary syndrome (PCOS) is a common heterogeneous endocrine disorder associated with metabolic syndrome (MetS). The aim of this systematic review and meta-analysis was to provide the most reliable estimate risk of MetS in women with PCOS, compared to healthy controls. METHODS A comprehensive literature search was performed in PubMed [including Medline], Web of Science and Scopus databases for retrieving articles in English language on the prevalence/incidence and odds of MetS in women with PCOS compared to healthy controls. Mantel-Haenszel methods of meta-analysis were used to present results in terms of the pooled odds ratio (OR) (95% confidence interval [CI]) using fixed/random-effects models with/without the publication bias correction, based on the various subgroups of age and study methods. Newcastle-Ottawa Scaling and The Cochrane Collaboration's risk of bias assessment tool were used to evaluate the quality of studies included. RESULTS The search strategy yielded 2759 potentially relevant articles of which 44 articles were included for meta-analysis. Results of the meta-analysis demonstrated that the patients with PCOS regardless of age, BMI and recruitment sources of samples had higher odds of MetS compared to healthy controls (OR 2.5, 95% CI 2.0-3.2). However, adolescents with PCOS had an increased odds of MetS compared to healthy adolescent controls in population- and nonpopulation-based studies (OR 4.7, 95% CI 1.8-11.9; OR 6.1, 95% CI 6.0- 6.1, respectively). However, the odds of MetS had no differences between adults with PCOS compared to healthy controls in population-based studies. These results were confirmed by the subgroup meta-analysis of some studies using age and BMI adjustment/matching. In addition, subgroup analysis based on diagnostic criteria of PCOS showed that the OR of MetS in PCOS using NIH criteria was higher than AES and Rotterdam criteria (Pooled Overall OR based on NIH criteria = 6.05, 95% CIL: 6.0-6.04). CONCLUSION These findings provide some information on the real features and a broader view of this syndrome that also helps clarify conflicting results documented in the literature. Accordingly, in prevention strategies, routine screening for metabolic syndrome is suggested for adolescents with PCOS.

Abstract
Background Polycystic ovary syndrome (PCOS) is a common but complex endocrine
disorder and is the major cause of anovulation and consequent subfertility. In this study
the effect of grape seed extract (GSE) on triglyceride (TG), total cholesterol (TC), highdensity lipoprotein-cholestrol (HDL-C), low-density lipoprotein-cholestrol (LDL-C) and
interleukin-6 (IL-6) in PCOS Wistar rats were assessed. Materials and Methods In this experimental study, 84 adult female Wistar rats were
divided into 7 groups (n=12) including control (intact), Sham (estradiol valerate solvent
injection), control PCOS and 4 experimental PCOS groups. To induce the syndrome, a
single subcutaneous injection of 2 mg estradiol valerate was applied. In experimental
groups, PCOS rats were treated with different doses of 50, 75, 100 and 200 mg/kg body
weight (BW) GSE by intraperitoneal injection for 10 consecutive days. After harvesting blood serum, TG was measured by Glycerol-3-phosphate Oxidase-Peoxidase (GPO-
PAP), TC by Cholesterol Oxidase-Peroxidase (CHOD-PAP), and HDL-C by sedimentation method, LDL-C by Friedwald calculation and IL-6 by ELISA method. The serum
values of each parameter were analyzed using one-way ANOVA at P≤0.05. Results In all experimental groups significant decrease of visceral fat was obvious as
compared with control PCOS group. LDL-C, TC and IL-6 levels in experimental groups,
particularly at dose of 50 mg/kg of GSE, were significantly decreased as compared with
PCOS group. However, HDL-C levels were not significantly changed. Conclusion : According to the findings of this study, it can be concluded that GSE with
its effects on serum TC, LDL-C and IL-6 could reduce the effects of dyslipidemia and
inflammation in PCOS rats and improve systemic symptoms of PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is a complex syndrome showing the clinical features of an endocrine/metabolic disorder, including hyperinsulinemia and hyperandrogenism. Two phenotypes are present, either lean or obese, with different biochemical, hormonal, and metabolic profiles. Evidence suggests many treatment modalities that can be applied. However, many of these modalities were found to be not suitable for the lean phenotype of PCOS. Much contradictory research was found regarding lean patients with PCOS. The aim of this narrative review is to shed light on the debate prevailing regarding characteristics, as well as metabolic, hematological, and potential management modalities. Literature review was performed from January 1, 2000 to March 31, 2017 with specific word search such as lean PCOS, hormonal abnormalities in lean PCOS, and the management of lean PCOS. All retrieved articles were carefully assessed, and data were obtained. We could conclude that the debate is still prevailing regarding this specific lean population with PCOS, especially with regard to their characteristics and management modalities. Further studies are still required to resolve this debate on the presence of PCOS in lean women.

Abstract
CONTEXT Normal weight polycystic ovary syndrome (PCOS) women may have altered adipose structure-function underlying metabolic dysfunction. OBJECTIVE This study examines whether adipose structure-functional changes exist in normal weight PCOS women and correlate with hyperandrogenism and/or hyperinsulinemia. DESIGN This is a prospective cohort study. SETTING The setting was an academic medical center. PATIENTS Six normal weight PCOS women and 14 age- and body mass index-matched normoandrogenic ovulatory (NL) women were included. INTERVENTION(S) All women underwent circulating hormone and metabolic measurements; frequently sampled intravenous glucose tolerance testing; total body dual-energy x-ray absorptiometry; abdominal magnetic resonance imaging; and SC abdominal fat biopsy. MAIN OUTCOME MEASURE(S) Circulating hormones and metabolites, body fat and its distribution, and adipocyte size were compared between PCOS and NL women, and were correlated with each other in all women. RESULTS Circulating LH and androgen levels were significantly greater in PCOS than NL women, as were fasting insulin levels, pancreatic β-cell responsiveness to glucose, and total abdominal fat mass. Intra-abdominal fat mass also was significantly increased in PCOS women and was positively correlated with circulating androgen, fasting insulin, triglyceride, and non-high-density lipoprotein cholesterol levels in all women. SC abdominal fat mass was not significantly increased in PCOS women, but contained a greater proportion of small SC abdominal adipocytes that positively correlated with serum androgen levels in all women. CONCLUSION Hyperandrogenism in normal weight PCOS women is associated with preferential intra-abdominal fat deposition and an increased population of small SC abdominal adipocytes that could constrain SC adipose storage and promote metabolic dysfunction.

Abstract
BACKGROUND The present study was aimed to investigate lipid profile in relation to anthropometric indices and insulin resistance in overweight or obese women with polycystic ovary syndrome (PCOS). METHODS In this cross-sectional study, lipid profile and anthropometric indices including body mass index (BMI), waist and hip circumference, waist to hip ratio (WHR), and waist to height ratio (WHtR) were evaluated in 63 overweight or obese PCOS patients subdivided into insulin-resistant (IR) and non insulin-resistant (NIR) groups. IR was defined as homeostasis model of insulin resistance (HOMA-IR) ≥3.8. RESULTS Fasting insulin concentration and HOMA-IR were higher (P<0.001) and high-density lipoprotein cholesterol (P=0.012) was lower in IR group. All of the anthropometric measures other than WHR and BMI showed significant correlations with several lipid parameters. Amongst, WHtR showed the strongest correlation with total cholesterol (TC) (r=0.37; P=0.004) and low density lipoprotein cholesterol (LDL-C) (r=0.33; P=0.011) in the whole PCOS patients. CONCLUSION Anthropometric characteristics (especially BMI and hip circum-ference) are more important parameters correlated to lipid profile than IR in overweight or obesePCOS patients, confirming the importance of early treat-ment of obesity to prevent dyslipidemia in the future.

Abstract
Polycystic ovary syndrome (PCOS) is frequently characterized by abdominal obesity and insulin resistance, which also represent the hallmarks of the metabolic syndrome (MetS). It is well established that MetS is associated with increased risk for both Type 2 diabetes mellitus and cardiovascular disease (CVD) and accumulating data suggest that PCOS is also a risk factor for Type 2 diabetes mellitus and CVD. Accordingly, the association of PCOS with MetS has major health care implications given also the high prevalence of both disorders. We aimed to critically analyze the major studies that compared the prevalence of MetS between women with PCOS and controls, to discuss the anthropometric, endocrine and metabolic characteristics of PCOS, which are implicated in the pathogenesis of Mets in women with PCOS and to comment on the implications and management of MetS in this population. We thus summarize the evidence regarding the prevalence of MetS in PCOS and discuss the primary determinants driving this association. Current evidence shows that MetS is frequently observed in women with PCOS, but this appears to be mainly due to the more pronounced abdominal obesity in these women and not due to PCOS per se. Lifestyle changes are the treatment of choice for MetS in women with PCOS, whereas pharmacotherapy should be individualized.

Abstract
OBJECTIVES The present study was performed to search whether subcutaneous and whole body adipose tissue increase and they relate to measures of insulin sensitivity in women with polycystic ovary syndrome (PCOS). MATERIALS AND METHODS 52 women with PCOS and 53 healthy controls, all with similar age and body mass index participated in the study. A skinfold caliper device was used to measure biceps, triceps, subscapular and suprailiac skinfold thickness (SFT). Mid-upper arm circumference (MUAC) was measured using a tape measure. Body fat distributions were determined by bioelectrical impedance analysis. Insulin resistance score was computed with the HOMA formula. Plasma adiponectin was measured by EIA. RESULTS SFT in all defined areas, MUAC, total body and trunk fat free mass, and HOMA score were higher in women with PCOS compared with healthy women, while adiponectin level was significantly lower. SFT values correlated positively with HOMA score, and negatively with blood adiponectin level. Regression analysis indicated, SFT in triceps and supscapular areas, trunk fat mass, trunk fat ratio, fat free mass and trunk fat free mass values as the most powerful predictors of HOMA score. CONCLUSIONS The present study showed that SFT in different body regions and fat-free tissue mass are increased in women with PCOS, with a significant relation to impaired insulin sensitivity.

Abstract
While many women with polycystic ovary syndrome (PCOS) are overweight, obese or centrally obese, the effect of excess weight on the outcomes of PCOS is inconsistent. The review aimed to assess the effects of overweight, obesity and central obesity on the reproductive, metabolic and psychological features of PCOS. MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials (CENTRAL) and PSYCINFO were searched for studies reporting outcomes according to body mass index categories or body fat distribution. Data were presented as mean difference or risk ratio (95% confidence interval). This review included 30 eligible studies. Overweight or obese women with PCOS had decreased sex hormone-binding globulin (SHBG), increased total testosterone, free androgen index, hirsutism, fasting glucose, fasting insulin, homeostatic model assessment-insulin resistance index and worsened lipid profile. Obesity significantly worsened all metabolic and reproductive outcomes measured except for hirsutism when compared to normal weight women with PCOS. Overweight women had no differences in total testosterone, hirsutism, total-cholesterol and low-density lipoprotein-cholesterol compared to normal weight women and no differences in SHBG and total testosterone compared to obese women. Central obesity was associated with higher fasting insulin levels. These results suggest that prevention and treatment of obesity is important for the management of PCOS.

Abstract
Obesity and insulin resistance play an important role in initiating or maintaining ill health in polycystic ovary syndrome (PCOS). This implies that treatment that reduces body weight and insulin resistance would alleviate the symptoms of PCOS. Lifestyle modification has been found to be effective in restoring reproductive function in up to 80% of individuals who achieve at least 5% weight loss. However, long-term weight maintenance is a challenge. This article provides a review of reduced glycemic load diets, including low glycemic index, very low carbohydrate, high-protein and high monounsaturated fat diets, on metabolic and reproductive health in PCOS and non-PCOS populations. Dietary trials in non-PCOS women suggest that higher-protein, reduced glycemic load diets were probably more beneficial than the conventional low-fat, high-carbohydrate diet but further studies are required to confirm this in PCOS women. Similarly, the optimal exercise regime for PCOS women remains to be investigated.

Abstract
OBJECTIVE To investigate the prevalence of metabolic syndrome in clomiphene citrate (CC) resistant polycystic ovary syndrome (PCOS) patients. METHODS 58 CC resistant PCOS patients, 52 CC responders, 53 fertile PCOS and 53 age and body mass index-matched normoandrogenic ovulatory fertile women were evaluated for metabolic syndrome. RESULTS Metabolic syndrome prevalence was 41.4% in CC resistants, in 23.1% of CC responders, in 11.3% of PCOS fertiles and 0% of controls (p < 0.0001). Waist circumference (WC) > 88 cm was 44.8%, systolic blood pressure (BP) ≥ 130 mmHg and diastolic BP ≥85 mmHg were 27.6%, TG (triglyceride) ≥150 mg/dL was 36.2%, HDL(high density lipoprotein) < 50 mg/dL was 63.8%, fasting glucose levels ≥ 100 mg/dL was 20.7% in CC resistant PCOS women. There were positive associations between CC resistance and WC >88 cm, BP ≥ 130 ≥ 85 mmHg, TG ≥ 150 mg/dL, HDL < 50 mg/dL, fasting glucose ≥ 100 mg/dL, and presence of metabolic syndrome (p < 0.05, for all). Moreover, WC > 88 cm, and HDL < 50 mg/dL were independent variables that were associated by CC resistance by multivariate regression analysis. CONCLUSIONS CC resistant PCOS patients have high prevalence of metabolic syndrome. These women have an increased risk of future cardiovascular disease.

Abstract
Polycystic ovary syndrome (PCOS) is associated with the metabolic syndrome (MetS). The metabolic disorders are not universal and may vary with race, age and phenotype. Our purpose was to determine the clinical and biochemical characteristics of Mediterranean PCOS women with MetS, compare them with non-MetS PCOS patients, and assess the ability of clinical data and biochemical tests to predict these abnormalities within our population. A total of 218 subjects, 196 PCOS women and 22 controls, undergo a physical examination and laboratory evaluation for a diagnosis of MetS. MetS was categorized according to NCEP ATP III guidelines. PCOS patients were analyzed separately and compared in three subgroups: three or more MetS criteria, two criteria, one or no criteria. The overall prevalence of MetS was 21.4%. Women with MetS had higher glucose (G) levels than PCOS women with two criteria (5.7 ± 1.5 vs 5 ± 0.4, p < 0.05). Both groups were comparable for all the other parameters. Waist circumference (WC), body mass index (BMI), systolic (SBP) and diastolic blood pressure (DBP), bioavailable testosterone (uT), triglycerides (TG) and insulin (I) levels were significantly higher and sex hormone-binding globulin (SHBG) levels, high-density lipoprotein (HDL), HOMA and QUICKI indexes significantly lower in both groups, MetS and patients with two criteria, compared with women with one or no criteria and the control group. WC, HDL and TG were the best predictors of PCOS patients at risk for MetS. In conclusion, we recommend considering PCOS patients with two criteria of MetS as having the same risk as patients with the full syndrome. Waist circumference with HDL and triglycerides is an efficient combined test to identify PCOS women at risk for metabolic and cardiovascular diseases.

Abstract
OBJECTIVE The aim of this study was to compare body fat distribution in PCOS with healthy controls and to investigate the factors associated with carotid artery intima media thickness (IMT) and insulin resistance. SUBJECTS AND METHODS A case control study was conducted in 46 women with PCOS and 43 age matched controls. Anthropometrical measurements, hormonal levels, lipid and glucose profile were evaluated. Body fat thickness in four regions and carotid IMT were measured. Body fat distribution was compared between groups. Correlation of these parameters with carotid artery IMT and insulin resistance was investigated. RESULT(S) Visceral and subcutaneous fat thickness and the mean carotid artery IMT were significantly higher in PCOS subjects (p < 0.01). In correlation analysis, age, body mass index (BMI) and waist hip ratio (WHR) showed correlation with carotid artery IMT (r = 0,55, p < 0,001; r = 0.41, p < 0.008 and r = 0.34 p = 0.03, respectively), whereas visceral fat thickness presented a correlation with HOMA-IR index as a sign of insulin resistance. CONCLUSION(S) Fat accumulation is more prominent in visceral and subcutaneous regions in PCOS. Increased BMI and abdominal type of obesity are closely related to the increased carotid artery IMT and insulin resistance. Weight control and regional weight loss are important part of the treatment for the future health of women with PCOS.

Abstract
OBJECTIVE To evaluate the asymmetric dimethylarginine (ADMA) and nitric oxide (NO) levels in obese and lean patients with polycystic ovarian syndrome (PCOS) and find out their relation with hormonal and metabolic parameters. METHODS Twenty-two obese, 18 lean patients with PCOS and 11 obese, 24 lean healthy control patients were enrolled prospectively. Plasma ADMA and NO levels and arginine/ADMA ratio were evaluated on 3rd day of menstrual cycle after at least 10 h overnight fasting. RESULTS Plasma ADMA, NO levels and arginine/ADMA ratio were similar in the groups. ADMA level did not correlate with the hormonal and metabolic parameters in patients with PCOS. However, NO correlated inversely with fasting insulin (r = -0.353, p = 0.041) and homeostasis model of insulin resistance (HOMA-IR) (r = -0.379, p = 0.027). Arginine/ADMA ratio also correlated inversely with fasting insulin (r = -0.339, p = 0.050). In multinomial regression analysis the risk of low NO was associated independently with high fasting insulin (OR = 1.19, 95% CI 1.001-1.42, p = 0.049) and high HOMA-IR in patients with PCOS (OR = 2.26, 95% CI 1.03-4.98, p = 0.042). CONCLUSIONS Insulin resistance may be the underlying mechanism of endothelial dysfunction through NO pathway in PCOS.

Abstract
INTRODUCTION Although polycystic ovary syndrome (PCOS) was described more than half a century ago, the underlying cause of PCOS is still unknown. The aim of our study was to evaluate whether serum resistin and adipocytokine levels alter and its changes relate with low grade inflammation in non-obese young women with PCOS. SUBJECTS AND METHODS Newly diagnosed 31 young non-obese women with PCOS (mean age 21.8 +/- 5.4 years; body mass index (BMI): 23.8 +/- 6.6 kg/m(2)) and 25 BMI- and age-matched, regular-cycling, healthy women (mean age 24.9 +/- 5.7 years; BMI: 23.1 +/- 5.8 kg/m(2)) were included the study Anthropometric measurements were evaluated. Resistin, adiponectin, glucose, insulin, hormone profiles, Lipoprotein (Lp)(a), high sensitive C reactive protein (hs-CRP), and homocysteine levels were measured in the beginning of oral glucose tolerance test. Homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. RESULTS Non-obese young women with PCOS had high adiponectin levels (28.01 +/- 6.47 ng/ml in PCOS vs. 23.89 +/- 7.70 ng/ml in control subjects, p = 0.034), whereas serum resistin levels were not significantly different compared with healthy controls (14.14 +/- 6.6 ng/ml in PCOS vs. 13.78 +/- 4.26 ng/ml in control subjects). There were no significant differences between two groups in terms of fasting insulin, Lp(a), homocysteine, and hs-CRP levels. Mean HOMA-IR value of patients with PCOS was similar with control subjects (1.93 +/- 0.73 in PCOS; 1.15 +/- 0.54 in control group). CONCLUSIONS Resistin levels did not change in non-obese young women with PCOS whereas adiponectin level in non-obese young women with PCOS was significantly higher than control subjects, perhaps, because of no insulin resistance. Circulating resistin levels may not be candidate to play a role in pathogenesis of PCOS without insulin resistance or obesity.

Abstract
PURPOSE To determine the prevalence of polycystic ovary syndrome (PCOS) in women who exercise regularly. METHODS All women under age 45 from an industrial company who had past history of exercising more than 6 months enrolled in this cross-sectional study. Prevalence of PCOS and comparison of BMI between PCOS and non-PCOS subgroups was done. The diagnosis of PCOS was based on the revised 2003 Rotterdam ESHRE/ASRM consensus criteria and exclusion of related disorders. RESULTS The prevalence of PCOS in was 8.8%; 95% CI: 8.5%-9.1%. In obese subjects, mean BMI differed significantly between PCOS and non-PCOS women (29.3 ±3.3 kg/m(2) vs. 27.8 ± 2 kg/m(2), P=0.03). In lean subjects, there was no statistically significant difference in terms of BMI between PCOS and non-PCOS women (21.4 ± 1.9 kg/m(2) vs. 21.2 ± 2 kg/m(2), P>0.05). CONCLUSION Obese PCOS patients show more difficulty in losing weight by exercise than lean PCOS patients. The role of hormonal alterations and PCOS per se in the responsiveness of weight loss to exercise remains to be determined.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a common condition in reproductive-aged women associated with impaired glucose tolerance (IGT), type 2 diabetes mellitus (DM2) and the metabolic syndrome. METHODS A literature search was conducted (MEDLINE, CINAHL, EMBASE, clinical trial registries and hand-searching) identifying studies reporting prevalence or incidence of IGT, DM2 or metabolic syndrome in women with and without PCOS. Data were presented as odds ratio (OR) [95% confidence interval (CI)] with fixed- and random-effects meta-analysis by Mantel-Haenszel methods. Quality testing was based on Newcastle-Ottawa Scaling and The Cochrane Collaboration's risk of bias assessment tool. Literature searching, data abstraction and quality appraisal were performed by two investigators. RESULTS A total of 2192 studies were reviewed and 35 were selected for final analysis. Women with PCOS had increased prevalence of IGT (OR 2.48, 95% CI 1.63, 3.77; BMI-matched studies OR 2.54, 95% CI 1.44, 4.47), DM2 (OR 4.43, 95% CI 4.06, 4.82; BMI-matched studies OR 4.00, 95% CI 1.97, 8.10) and metabolic syndrome (OR 2.88, 95% CI 2.40, 3.45; BMI-matched studies OR 2.20, 95% CI 1.36, 3.56). One study assessed IGT/DM2 incidence and reported no significant differences in DM2 incidence (OR 2.07, 95% CI 0.68, 6.30). One study assessed conversion from normal glucose tolerance to IGT/DM2 (OR 2.4, 95% CI 0.7, 8.0). No studies reported metabolic syndrome incidence. CONCLUSIONS Women with PCOS had an elevated prevalence of IGT, DM2 and metabolic syndrome in both BMI and non-BMI-matched studies. Few studies have determined IGT/DM2 or metabolic syndrome incidence in women with and without PCOS and further research is required.

Abstract
Women with polycystic ovarian syndrome (PCOS) have been shown to have a very high prevalence of obstructive sleep apnea (OSA). Screening for OSA is recommended for PCOS patients. How far this is carried out in actual practice is unknown. To study practice patterns with regard to screening for OSA in physicians-both obstetrician/gynecologists (ObGyn) and endocrinologist-who manage PCOS. A secondary aim of this study was to identify practice differences, if any. Two hundred ObGyn and 140 endocrine academic institutions were contacted and mailed with questionnaires, if willing to participate. Responses were obtained from 50 (29.4%) ObGyn physicians and 29 (26.4%) endocrine physicians. The questionnaire was closed-ended. Physicians reported a high occurrence of obesity-36.7% of the physicians reported that 75-100% of their patients had morbid obesity. However, reported prevalence of symptoms was low-86.1% of the physicians felt their patients snored infrequently (<25% of the time) and 74.7% felt that their patients had excess daytime sleepiness (EDS) infrequently. Of the physicians, 92.4% ordered a sleep study <25% of the time. No significant difference in practice between the specialties was identified. Physicians who manage PCOS patients do not believe that these patients have significant symptoms nor warrant frequent testing for OSA. This may reflect lack of knowledge about the link or may imply that PCOS patients remain largely asymptomatic. Educating specialist physicians managing PCOS about OSA and improved tools for OSA screening may improve detection.

Abstract
OBJECTIVE To assess the resting metabolic rate (RMR) and exercise capacity (or maximal oxygen consumption [VO2 max]) of women with polycystic ovary syndrome (PCOS) and central adiposity. METHOD In a cross-sectional study, RMR was measured by indirect calorimetry and VO2 max by the Astrand test for 31 women with PCOS and 29 controls matched for age and body mass index, but with a different body fat distribution. Differences between the means were analyzed. RESULTS There were no significant differences in RMR or VO2 max values between the 2 groups. CONCLUSION Central adiposity was not predictive of an altered RMR or of decreased exercise capacity in women with PCOS.

Abstract
The aim of this study was to determine the prevalence of metabolic syndrome in women with polycystic ovary syndrome, as well as its characteristics and predictors. Seventh-three women, with body mass index of 30.4 ± 7.8 kg/m² and 25.0 ± 6.0 years old, subdivided according to body mass index, were studied retrospectively. There was no significant mean age difference among body mass index groups (p = 0.228). Prevalence of metabolic syndrome was 38.4%, with a null prevalence for normal (n = 18), 23.8% for overweight (n = 17), 62.9% for obese (n = 28), and 85.5% for morbidly obese women (n = 7). Women with metabolic syndrome were older than women without metabolic syndrome (27.3 ± 5.3 vs. 24.2 ± 4.6 vs. years old; p = 0.031) and presented a higher body mass index (36.3 ± 7.7 vs. 26.9 ± 5.4; p < 0.001). There was no difference for degree of hirsutism and menstrual patterns between women with and without metabolic syndrome (p = 0.593 and p = 0.119, respectively). Regarding laboratory parameters, DHEAS was lower (1,646 ± 1,007 vs. 2,594 ± 1,563; p = 0.007) and HOMA-IR were higher (9.9 ± 9.7 vs. 4.6 ± 4.7; p = 0.004) in women with metabolic syndrome (p = 0.031 and p < 0.001, respectively). The best predictors of metabolic syndrome were waist circumference > 88 cm, HDL-cholesterol < 50 mg/dL and triglycerides > 150 mg/dL.

Abstract
CONTEXT Increased abdominal fat has been linked to insulin resistance and increased cardiovascular risk. Because many patients with polycystic ovary syndrome (PCOS) present abdominal obesity, it may be the cause of insulin resistance in this disorder. SETTING Fat quantity and distribution were evaluated by dual x-ray absorptiometry at the Departments of Clinical Medicine at the University of Palermo and the University of Naples, Italy. PATIENTS A total of 110 patients with PCOS and 112 weight-matched controls were studied. Anthropometric data, blood glucose, serum insulin, and testosterone were evaluated. Total, trunk, and central abdominal fat quantity were measured by total-body dual x-ray absorptiometry. RESULTS Compared with weight-matched controls, patients with PCOS had similar quantity of total and trunk fat but higher quantity of central abdominal fat. This difference was not observed when comparing obese PCOS and obese controls but depended on differences between overweight and normoweight patients and controls. All obese subjects, independently of having PCOS or not, had increased central abdominal fat. The same parameter was increased in 71% of overweight PCOS, 50% of overweight controls, and 30% of normoweight PCOS patients. PCOS patients with increased central abdominal fat had significantly higher (P < 0.01) insulin levels and significantly reduced (P < 0.01) insulin sensitivity than controls with similar quantities of central abdominal fat. Overweight PCOS patients with normal abdominal fat had significantly higher (P < 0.05) insulin levels and significantly reduced (P < 0.05) insulin sensitivity than overweight controls with normal abdominal fat. CONCLUSIONS Most obese subjects, independent of being affected by PCOS, have an abdominal form of obesity. However, abdominal fat excess may not be the only determinant of insulin resistance in PCOS.

Abstract
BACKGROUND The primary aim of weight loss intervention in obesity is the loss of fat mass (FM). Hence, determinations of changes in FM and fat free mass (FFM) during weight loss are of clinical value. The authors compared the clinical utility of SkinFold Thickness (SKF), tetrapolar bioelectrical impedance analysis (BIA) and a body mass index (BMI) based calculation, in determining changes in percentage of fat mass (delta%FM). METHODS Using dual X-ray absorptiometry (DEXA) measurements of %FM as a standard, BIA, SKF and BMI were compared in 41 moderately obese women (BMI 30-35) before and after significant weight loss (-13.9 +/- 5.8 kg). RESULTS When measuring fat mass loss, SKF was precise and accurate with a bias of +0.86 +/- 6.16 %, while the BMI-based estimation had a systematic bias of +6.36 +/- 6.04 % (r2 = 0.791, P < 0.001). BIA using the Lukaski formula had a bias of +5.22 % and limits of agreement that approached the magnitude of the measurement (+/- 20.82 %), thus providing no information. In contrast, BIA using the Segal formula had a systematic bias of +7.81% (r2 = 0.636, P < 0.001) and gave narrower limits of agreement (+/- 8.34 %). CONCLUSION For measuring changes in %FM with weight loss, BIA has no clinical value using the Lukaski formula, and using the Segal formula BIA provided no additional information to that given by BMI. We show that BIA instrument variables confound the estimates of %FM achieved by the BMI component of the Lukaski and Segal formulas.

Abstract
OBJECTIVE To determine the prevalence of the metabolic syndrome (MetS) and its components in Brazilian women with polycystic ovary syndrome (PCOS). DESIGN Cross-sectional study. SETTING University Hospital, Federal University of Rio Grande do Norte, Natal-RN, Brazil. PATIENT(S) 102 women with PCOS by the Rotterdam consensus criteria. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Clinical and biochemical parameters for MetS as defined by the National Cholesterol Education Program Adult Treatment Panel (NCEP ATP III). RESULT(S) The prevalence for individual components of MetS were high-density lipoprotein cholesterol level <50 mg/dL in 69.6%, waist circumference >or=88 cm in 57.9%, triglyceride level >or=150 mg/dL in 31.7%, blood pressure >or=130/85 mm Hg in 18.6%, and fasting glucose concentrations >or=110 mg/dL in 2.9%. Three or more of these individual criteria were present in 29 (28.4%) of the patients. The prevalence of MetS increased with body mass index: 3.2%, 19.2% and 52.3% for normal, overweight, and obese women, respectively. CONCLUSION(S) These findings indicate that Brazilian women with PCOS have a high prevalence of MetS and its individual components, particularly a decreased high-density lipoprotein cholesterol level. Thus, these women are at increased risk of diabetes mellitus and cardiovascular disease.

Abstract
BACKGROUND An association has been proposed between polycystic ovary syndrome (PCOS) and pregnancy-induced hypertensive disorders. Ambulatory blood pressure and carotid artery elasticity were therefore prospectively investigated in matched PCOS and control pregnancies. METHODS Twenty-two PCOS-control subject pairs with singleton pregnancies, matched for age, body mass index, parity and ethnicity, were recruited in the first trimester (T1, 11-13 weeks). Ambulatory blood pressure recording for 24 h and carotid artery ultrasound for elasticity estimation were performed in T1 and in the second (T2, 22-24 weeks) and third (T3, 32-34 weeks) trimesters. RESULTS At nearly all time points during gestation, ambulatory systolic, diastolic and mean arterial pressures were elevated in PCOS versus control pregnancies. Carotid artery stiffness index was greater and compliance was less in PCOS pregnancies compared with controls. Differences in night-time systolic pressure and carotid artery elasticity were greatest in T3. PCOS also increased the incidence of pregnancy-induced hypertension (6 of 22 cases versus 0 of 22 in controls; P = 0.011). CONCLUSIONS Pregnant women with PCOS have higher baseline ambulatory blood pressure and impaired arterial elasticity, suggestive of disturbed vascular adaptation to pregnancy.

Abstract
The cardiovascular risk associated with the polycystic ovary syndrome (PCOS) has recently attracted much interest. Women with PCOS are more likely to fulfill the diagnosis of the metabolic syndrome, a cluster of related cardiometabolic factors known to predict long-term risk of cardiovascular disease and type 2 diabetes. We review the literature pertaining to the link between the metabolic syndrome, cardiovascular disease, and PCOS. We focus on the influence of obesity and hyperandrogenemia, and on strategies for identifying cardiovascular risk in PCOS.
