Abstract
PROBLEM Polycystic ovary syndrome (PCOS), a prevalent endocrine-metabolic disorder, presents considerable therapeutic challenges due to its complex and elusive pathophysiology. METHOD OF STUDY We employed three machine learning algorithms to identify potential biomarkers within a training dataset, comprising GSE138518, GSE155489, and GSE193123. The diagnostic accuracy of these biomarkers was rigorously evaluated using a validation dataset using area under the curve (AUC) metrics. Further validation in clinical samples was conducted using PCR and immunofluorescence techniques. Additionally, we investigate the complex interplay among immune cells in PCOS using CIBERSORT to uncover the relationships between the identified biomarkers and various immune cell types. RESULTS Our analysis identified ACSS2, LPIN1, and NR4A1 as key mitochondria-related biomarkers associated with PCOS. A notable difference was observed in the immune microenvironment between PCOS patients and healthy controls. In particular, LPIN1 exhibited a positive correlation with resting mast cells, whereas NR4A1 demonstrated a negative correlation with monocytes in PCOS patients. CONCLUSION ACSS2, LPIN1, and NR4A1 emerge as PCOS-related diagnostic biomarkers and potential intervention targets, opening new avenues for the diagnosis and management of PCOS.

Abstract
BACKGROUND Accumulating evidence suggests a strong association between polycystic ovary syndrome (PCOS) and ovarian cancer (OC), but the potential molecular mechanism remains unclear. In this study, we identified previously unrecognized genes that are significantly correlated with PCOS and OC via bioinformatics. MATERIALS AND METHODS Multiple bioinformatic analyses, such as differential expression analysis, univariate Cox analysis, functional and pathway enrichment analysis, protein-protein interaction (PPI) network construction, survival analysis, and immune infiltration analysis, were utilized. We further evaluated the effect of OGN on FSHR expression via immunofluorescence. RESULTS TCGA-OC, GSE140082 (for OC) and GSE34526 (for PCOS) datasets were downloaded. Twelve genes, including RNF144B, LPAR3, CRISPLD2, JCHAIN, OR7E14P, IL27RA, PTPRD, STAT1, NR4A1, OGN, GALNT6 and CXCL11, were identified as signature genes. Drug sensitivity analysis showed that OGN might represent a hub gene in the progression of PCOS and OC. Experimental analysis found that OGN could increase FSHR expression, indicating that OGN could regulate the hormonal response in PCOS and OC. Furthermore, correlation analysis indicated that OGN function might be closely related to m6A and ferroptosis. CONCLUSIONS Our study identified a 12-gene signature that might be involved in the prognostic significance of OC. Furthermore, the hub gene OGN represent a significant gene involved in OC and PCOS progression by regulating the hormonal response.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Saffron petal has traditionally been used to treat a variety of diseases, such as gynecological disease such as primary dysmenorrhea and premenstrual tension. Polycystic Ovary Syndrome (PCOS) is a form of gynecological disease that causes amenorrhea, infertility, menopausal and urogenital disorders. This disease may be treated with saffron petals. AIM OF THE STUDY In this study, the effects of saffron petal extract (SPE) and saffron petal anthocyanins (SPA) on ovarian hormones, steroidogenic enzymes, ovarian dysfunction, regulation of anti-inflammatory genes, and antioxidant factors in female PCOS mice were studied. METHODS AND RESULTS The PCOS mouse model was induced by testosterone enanthate (TE), and an in vivo evaluation of whether the dietary consumption of SPE and SPA improved the PCOS-like symptoms was conducted. The luteinizing hormone (LH), testosterone, and estrogen levels increased in PCOS mice, but decreased following SPE and SPA treatment. In the PCOS mice, the reduced follicular-stimulating hormone (FSH) progesterone levels were restored to that of normal controls with SPE and SPA treatment in serum. The transcription level(s) of gonadotropin receptors (Fshr and Lhr), steroid receptors (Pgr, and Esr1), inflammatory markers (TNFα, IL1ß, IL6 and IL18), inflammatory-related factors (NF-κB, NF-κB p65, IκB) and antioxidant enzymes (GPx, SOD, CAT, GST, and GSH) changed under the PCOS condition. Moreover, they were regulated by SPE and SPA treatment in PCOS mice ovaries. The reproductive tissues of TE induced PCOS mice were restored into estrogenic conditions from androgen environments. The study of antioxidant activity of SPE and SPA using FRAP and DPPH tests showed high antioxidant activity. CONCLUSION These results suggest that SPE and SPA ameliorates symptoms of PCOS by improving dysregulation of ovarian steroids, steroidogenic, antioxidant enzymes and inflammatory markers in PCOS mice.

Abstract
CONTEXT Polycystic ovary syndrome (PCOS) is a common endocrine disorder associated with low-grade inflammation and increased incidence of pregnancy complications, but its influence on the maternal immune system in pregnancy is unknown. Longitudinal serum cytokine profiling is a sensitive measure of the complex immunological dynamics of pregnancy. OBJECTIVE This work aimed to determine the immunological dynamics of serum cytokines throughout pregnancy in women with PCOS and compare it to pregnancy in women without PCOS. METHODS A post hoc analysis was conducted of longitudinal serum samples from 2 randomized, placebo-controlled multicenter studies of pregnant women with PCOS and 2 studies of pregnant women without PCOS. Pregnant women with PCOS (n = 358) and without PCOS (n = 258, controls) provided 1752 serum samples from 4 time points in pregnancy (weeks 10, 19, 32, and 36). Main outcome measures included maternal serum levels of 22 cytokines and C-reactive protein (CRP) at 4 time points in pregnancy. RESULTS Women with PCOS showed marked immunological changes in serum cytokines throughout pregnancy. Compared to controls, women with PCOS showed higher levels of 17 cytokines and CRP at week 10 of pregnancy and a distinct cytokine development throughout pregnancy. The immunological dynamics in women with PCOS was significantly affected by maternal body mass index, smoking, and fetal sex. CONCLUSION Pregnancy in women with PCOS was associated with a strong early mobilization of inflammatory and other serum cytokines persisting throughout pregnancy, indicating a more activated immune status. These findings provide a novel basis for further study of PCOS and pregnancy complications.

Abstract
Hyperandrogenemia and ovulatory dysfunction are hallmarks of polycystic ovary syndrome (PCOS), pointing to a deranged hypothalamus-pituitary-ovarian (HPO) axis. An autoimmune etiology of PCOS is suspected in a subset of patients due to the relatively high concordance of PCOS with common autoimmune diseases. For this reason, we tested the hypothesis that natural autoantibodies (aAb) to the follicle-stimulating hormone receptor (FSHR) or luteinizing hormone receptor (LHR) are prevalent in PCOS. To this end, new luminometric assays for quantifying aAb to the FSHR (FSHR-aAb) or LHR (LHR-aAb) were developed using full-length recombinant human receptors as fusion proteins with luciferase as reporter. Prevalence of FSHR-aAb and LHR-aAb was determined in serum samples from healthy controls and PCOS patients. Steroid hormone profiles were compared between patients with and without FSHR-aAb or LHR-aAb. Signal linearity and detection ranges were characterized and both methods passed basic performance quality checks. The analysis revealed a relatively low prevalence, with 4 out of 430 samples positive for FSHR-aAb in the control versus 11 out of 550 samples in the PCOS group, i.e., 0.9% versus 2.0%, respectively. Similarly, there were only 5 samples positive for LHR-aAb in the control versus 2 samples in the PCOS group, i.e., 1.2% versus 0.4%, respectively. Samples positive for FSHR-aAb displayed steroid hormones in the typical range of PCOS patients, whereas the two samples positive for LHR-aAb showed relatively elevated free testosterone in relation to total testosterone concentrations with unclear significance. We conclude that the FSHR and LHR constitute potential autoantigens in human subjects. However, the prevalence of specific autoantibodies to these receptors is relatively low, both in control subjects and in women with PCOS. It is therefore unlikely that autoimmunity to the LHR or FSHR constitutes a frequent cause of hyperandrogenemia or ovulatory dysfunction in PCOS.

Abstract
BACKGROUND Immune dysfunction is one of the mechanisms to promote polycystic ovary syndrome (PCOS). Various immune cells have been reported to be involved in the development of PCOS. Meanwhile, the disturbance of metabolism is closely related to PCOS. The aim of this study is to explore the association of mucosal-associated invariant T (MAIT) cells and myeloid-derived suppressor cells (MDSCs) with the metabolic dysfunction in PCOS. METHODS 68 PCOS patients and 40 controls were recruited in this study and we collected the peripheral blood of participants' during their follicular phase. The frequencies of MAIT cells and MDSCs were determined by flow cytometry after being stained with different monoclonal antibodies. And the concentrations of cytokines were determined by ELISA. RESULTS Compared to controls with normal metabolism, the frequency of MDSCs, CD8+MAIT cells and CD38+CD8+MAIT cells were significantly decreased in PCOS patients with normal metabolism, however, proportion of CD4+MAIT cells exhibited a noticeable increase. Similar results of CD8+MAIT, CD38+CD8+MAIT cells and reduced expression of IL-17 were observed in PCOS patients with metabolic dysfunction as compared to controls with metabolic disorders. PCOS patients with excessive testosterone levels displayed significantly decreased levels of CD8+MAIT, CD38+CD8+MAIT cells, MDSCs and Mo-MDSCs as compared to PCOS patients with normal testosterone concentrations. PCOS patients with abnormal weight showed a lower level and activation of CD8+MAIT cells. On the contrary, they displayed an enrichment of CD4+MAIT cells. PCOS patients with glucose metabolic disorder displayed a remarkable dysregulation of MDSCs and Mo-MDSCs. MDSCs were positively correlated with MAIT cells. Negative correlations between the frequency of CD8+MAIT cells, CD38+CD8+MAIT cells and body mass index were revealed. CD4+MAIT cells positively correlated with BMI. Mo-MDSCs were found to be negatively related to the levels of 2hour plasma glucose and HOMA-IR index. CONCLUSION The impairment of CD8+MAIT cells and MDSCs is involved in the metabolic dysfunction of PCOS.

Abstract
Background rs13405728 was identified as one of the most prevalent susceptibility loci for polycystic ovary syndrome (PCOS) in Han Chinese and Caucasian women. However, the target genes and potential mechanisms of the rs13405728 locus remain to be determined. Methods Three-dimensional (3D) genome interactions from the ovary tissue were characterized via high-through chromosome conformation capture (Hi-C) and Capture Hi-C technologies to identify putative targets at the rs13405728 locus. Combined analyses of eQTL, RNA-Seq, DNase-Seq, ChIP-Seq, and sing-cell sequencing were performed to explore the molecular roles of these target genes in PCOS. PCOS-like mice were applied to verify the expression patterns. Results Generally, STON1 and FSHR were identified as potential targets of the rs13405728 locus in 3D genomic interactions with epigenomic regulatory peaks, with STON1 (P=0.0423) and FSHR (P=0.0013) being highly expressed in PCOS patients. STON1 co-expressed genes were associated with metabolic processes (P=0.0008) in adipocytes (P=0.0001), which was validated in the fat tissue (P<0.0001) and ovary (P=0.0035) from fat-diet mice. The immune system process (GO:0002376) was enriched in FSHR co-expressed genes (P=0.0002) and PCOS patients (P=0.0002), with CD4 high expression in PCOS patients (P=0.0316) and PCOS-like models (P=0.0079). Meanwhile, FSHR expression was positively correlated with CD4 expression in PCOS patients (P=0.0252) and PCOS-like models (P=0.0178). Furthermore, androgen receptor (AR) was identified as the common transcription factor for STON1 and FSHR and positively correlated with the expression of STON1 (P=0.039) and FSHR (P=4e-06) in ovary tissues and PCOS-like mice. Conclusion Overall, we identified STON1 and FSHR as potential targets for the rs13405728 locus and their roles in the processes of adipocyte metabolism and CD4 immune expression in PCOS, which provides 3D genomic insight into the pathogenesis of PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is described as a low-grade chronic inflammatory state. However, there are limited studies on the specific endometrial immune status of PCOS patients. Whether this endometrial immune cell pattern is intrinsic to PCOS or the consequence of PCOS-associated obesity is a subject of debate. This study retrospectively included one hundred women diagnosed with PCOS and ninety-five normal fertile controls, which further divided into four groups (normoweight PCOS; overweight PCOS; normoweight control; overweight control) based on body mass index. The percentages of endometrial CD68+ macrophages (1.97 % vs. 1.17 %; P < 0.001), CD163+ M2 macrophages (2.30 % vs. 1.83 %; P = 0.001), CD1a+ iDCs (0.044 % vs. 0.029 %; P = 0.002), CD83+ mDCs (1.72 % vs. 1.07 %; P < 0.001) and CD8+ T cells (2.82 % vs. 1.95 %; P < 0.001) were significantly higher in normoweight PCOS women than normoweight controls. The percentage of CD68+ macrophages (2.09 % vs. 1.15 %; P < 0.001) was significantly higher in overweight PCOS women compared with overweight controls. In multivariant linear regression analysis, participants' PCOS status was the main predictors of endometrial CD68+ macrophages, CD163+ M2 macrophages, CD1a+ iDCs, CD83+ mDCs and CD8+ T cells in the whole study population. Additionally, in PCOS group, positive correlations were found between endometrial CD56+ NK, CD163+ M2 macrophages and QUICKI, indicating there was an association between endometrial immune cells and insulin resistance in PCOS women. Our study suggests that women with PCOS have altered endometrial immune cells, which may reflect a state of chronic low grade inflammation. The chronic inflammation, independent of obesity, may help understand the pathophysiologic mechanisms of intrinsic PCOS.

Abstract
The impact of diet on inflammation and oxidative stress (OS) in girls with polycystic ovary syndrome (PCOS) is unknown. Therefore, our study aimed to investigate, in PCOS girls, whether certain macronutrient intakes can be associated with these disturbances. For this purpose, 59 PCOS participants (aged 14-18 years) were recruited to this study and divided into two subgroups: overweight/obese-Ov/Ob group (n = 22) and normal weight-N group (n = 37). Nutrition was assessed using a 3-day food record. The studied markers were total antioxidant capacity (TAC), malondialdehyde (MDA), C-reactive protein (CRP), tumor necrosis factor α (TNF-α), and interleukins 1 and 6 (IL-1 and IL-6). We found plant protein intake inversely correlated with IL-6 (p = 0.007; r = -0.557), TNF-α (p = 0.006; r = -0.564), MDA (p = 0.01; r = -0.539) in the Ov/Ob group and with TAC (p = 0.021; r = -0.38) in the N group. Inverse correlations in the Ov/Ob group were observed between protein intake and IL-6 (p = 0.031; r = -0.461), TNF- α (p = 0.043; r = -0.435); carbohydrates and IL-6 (p = 0.037; r = -0.448), MDA (p = 0.045; r = -0.431); fiber and IL-6 (p = 0.025; r = -0.475). A positive relationship between cholesterol intake and CRP concentration (p = 0.038; r = 0.342) was also found in the N group. These findings revealed that inflammation and OS are increased in Ov/Ob girls with decreased plant protein intake and low carbohydrates in the diet. Moreover, inflammation may be increased by cholesterol intake in slim PCOS girls. On the other hand, decreased intake of fiber and total protein intake increased inflammation.

Abstract
BACKGROUND Women with polycystic ovary syndrome (PCOS) often have vitamin D deficiency, a known risk factor for severe COVID-19 disease. Alveolar macrophage-derived cytokines contribute to the inflammation underlying pulmonary disease in COVID-19. We sought to determine if basal macrophage activation, as a risk factor for COVID-19 infection, was present in PCOS and, if so, was further enhanced by vitamin D deficiency. METHODS A cross-sectional study in 99 PCOS and 68 control women who presented sequentially. Plasma levels of a macrophage-derived cytokine panel were determined by Slow Off-rate Modified Aptamer (SOMA)-scan plasma protein measurement. Vitamin D was measured by tandem mass spectroscopy. RESULTS Vitamin D was lower in PCOS women (p<0.0001) and correlated negatively with body mass index (BMI) in PCOS (r=0.28, p=0.0046). Basal macrophage activation markers CXCL5, CD163 and MMP9 were elevated, whilst protective CD200 was decreased (p<0.05); changes in these variables were related to, and fully accounted for, by BMI. PCOS and control women were then stratified according to vitamin D concentration. Vitamin D deficiency was associated with decreased CD80 and IFN-γ in PCOS and IL-12 in both groups (p<0.05). These factors, important in initiating and maintaining the immune response, were again accounted for by BMI. CONCLUSION Basal macrophage activation was higher in PCOS with macrophage changes related with increased infection risk associating with vitamin D; all changes were BMI dependent, suggesting that obese PCOS with vitamin D deficiency may be at greater risk of more severe COVID-19 infection, but that it is obesity-related rather than an independent PCOS factor.

Abstract
OBJECTIVES Our study aimed to explore the relationship between leptin and IFN-γ in PCOS patients, and confirmed the effect of leptin-induced IFN-γ on granulosa cells furtherly. METHODS 29 patients with PCOS and 36 healthy controls were enrolled. Leptin level and the proportion of Th1 cells were detected and association between them were analyzed. Meanwhile, peripheral blood mononuclear cells (PBMCs) isolated from PCOS patients were treated with leptin and then the proportion of Th1 was analyzed. Besides that, the apoptotic level of KGN cells was monitored after IFN-γ treatment. RESULTS In the circulation of PCOS patients, leptin level dramatically increased compared with controls. And, this was associated with upregulated Th1 cells proportion and IFN-γ level. In vitro, Th1 cells proportion increased after leptin treated PBMCs from PCOS patients. Furthermore, for KGN cells, the percentage of live cells decreased and later apoptosis cells increased after IFN-γ treatment. CONCLUSIONS Our results indicated that leptin takes part in process of PCOS via inducing expression of IFN-γ. Our findings highlight the importance of the connection between leptin and inflammation in PCOS and provide new insights therapeutic strategy for this disease.

Abstract
Objective: It has been shown that women with polycystic ovary syndrome (PCOS), as well as Hashimoto's thyroiditis (HT), are characterized by increased incidence of infertility. Serum anti-Müllerian hormone (AMH), which reflects ovarian reserve, is elevated in PCOS women and is decreased in women with HT. The Rotterdam criteria recognize four clinical PCOS phenotypes, i.e., phenotypes A, B, C, and D. The aim of the present study was to investigate the relation between serum concentrations of thyroid peroxidase antibodies (TPOAbs) and ovarian reserve in different PCOS phenotypes. Patients and methods: We examined 141 women with PCOS [phenotype A was diagnosed in 67 (47.5%) women, phenotype B in 30 (21.3%), phenotype C in 28 (19.9%), and phenotype D in 16 (11.3%)] and 88 control subjects of similar age; all women were euthyroid. Serum concentrations of AMH, thyroid-stimulating hormone (TSH), thyroid hormones, and TPOAbs were assessed. Results: We observed positive serum TPOAbs in 21.9% women with PCOS and in 23.9% controls (p = 0.07). We did not find differences in the frequency of detection of positive serum TPOAbs between phenotypes A, B, and C and the control group (p > 0.05). We did not observe a difference in AMH levels between TPOAbs-positive and TPOAbs-negative women, both in the control group and the PCOS women (all p > 0.05). However, serum AMH concentration was markedly higher in the whole PCOS group (p < 0.01) and in phenotype A (p < 0.01) vs. controls when the serum concentration of TPOAbs was negative. In the groups with positive serum levels of TPOAbs, serum concentration of AMH did not differ between PCOS phenotypes and controls (p = 0.23). Additionally, we observed that serum AMH concentration was related to the level of TPOAbs in the PCOS group (r = -0.4, p = 0.02). Conclusions: The frequency of serum detection of positive TPOAbs did not differ between PCOS phenotypes with clinical/biochemical hyperandrogenism and the control group. The observation of the difference in serum AMH between the PCOS and control groups only in TPOAbs negative women together with the inverse relation of TPOAbs with serum AMH only in the PCOS group might suggest that ovarian reserve is influenced by TPOAbs in PCOS.

Abstract
CONTEXT Polycystic ovary syndrome (PCOS) is a chronic disease affecting reproductive function and whole-body metabolism. Although the etiology is unclear, emerging evidence indicates that the epigenetics may be a contributing factor. OBJECTIVE To determine the role of global and genome-wide epigenetic modifications in specific immune cells in PCOS compared with controls and whether these could be related to clinical features of PCOS. DESIGN Cross-sectional study. PARTICIPANTS Women with (n = 17) or without PCOS (n = 17). SETTING Recruited from the general community. MAIN OUTCOME MEASURES Isolated peripheral blood mononuclear cells were analyzed using multicolor flow cytometry methods to determine global DNA methylation levels in a cell-specific fashion. Transcriptomic and genome-wide DNA methylation analyses were performed on T helper cells using RNA sequencing and reduced representation bisulfite sequencing. RESULTS Women with PCOS had lower global DNA methylation in monocytes (P = 0.006) and in T helper (P = 0.004), T cytotoxic (P = 0.004), and B cells (P = 0.03). Specific genome-wide DNA methylation analysis of T helper cells from women with PCOS identified 5581 differentially methylated CpG sites. Functional gene ontology enrichment analysis showed that genes located at the proximity of differentially methylated CpG sites belong to pathways related to reproductive function and immune cell function. However, these genes were not altered at the transcriptomic level. CONCLUSIONS It was shown that PCOS is associated with global and gene-specific DNA methylation remodeling in a cell type-specific manner. Further investigation is warranted to determine whether epigenetic reprogramming of immune cells is important in determining the different phenotypes of PCOS.

Abstract
Polycystic ovary syndrome (PCOS), as systemic disease, is accompanied by different indexes of inflammation. Free light chains of immunoglobulins (FLCs), produced by plasmacells, are released in slight excess for the immune requests, with still poorly defined physiological role but surely they represent a marker of inflammation. In order to evaluate their levels and correlate them with hyperandrogenism, we have studied a group of PCOS patients, age range 18-37 yrs, mean ± SEM body mass index (BMI) 24.1 ± 0.9 kg/m2), compared with age- and BMI-matched controls, with assay of k and λ FLCs, by turbidimetric method, and their ratio in blood plasma. PCOs exhibited higher levels vs. controls: (mean ± SEM λ: 10.0 ± 0.85 mg/L vs. 8.41 ± 0.45 mg/L; k: 12.45 ± 0.72 mg/L vs. 6.41 ± 0.34 mg/L; k/λ: 1.31 ± 0.07 vs. 0.78 ± 0.04). A significant direct correlation was observed between λ-FLCs and testosterone levels, no correlation was indeed found with HOMA-IR index. These data confirm high levels of FLCs in PCOS, suggesting systemic inflammatory state and a possible role in the pathophysiology of such complex syndrome.

Abstract
The immune etiology of polycystic ovary syndrome (PCOS) is an intriguing area. However, whether there is alteration in the leukocyte populations in different tissues remain ambiguous. AIM To characterize the leukocyte populations of hyperandrogenemic female (HAF) rat tissues. METHODS Female Sprague Dawley rats at 3 weeks of age were implanted subcutaneously with dihydrotestosterone (DHT) or placebo pellets. The rats were aged to 14-15 weeks and tissues were collected. RESULTS Peripheral blood (PB) and renal CD4+ (P < 0.03, P < 0.007), Th17 (P < 0.05, P < 0.002), and CD4+CD28null (P < 0.04, P < 0.001) were significantly increased in HAF rats compared to placebo, respectively, in spite of their lower percentage in the spleen. Although, the percentage of Treg T lymphocytes were significantly higher in the PB (P < 0.001) of HAF rats, the splenic (P < 0.01) and renal Treg cells (P < 0.03) were found to be significantly lower. Remarkably, HAF rats had higher renal mast cells (P < 0.00009) despite lower splenic (P < 0.002). The number of PB, renal, and splenic CD8+ T cells and IgM+-B cells in HAF rats remained unchanged. CONCLUSION Results from this study 1) provide the first evidence of significant alteration of T lymphocyte subsets and different leukocyte populations profile in a rat model of polycystic ovary syndrome, 2) demonstrate alteration of the immunological niche of blood, spleen, and kidney tissues in Hyperandrogenemia state in female rats, 3) imply potential immune system dysregulation in HAF rats which may suggest a link between excess androgen, chronic inflammation, and immune-mediated diseases in polycystic ovary syndrome patients.

Abstract
Stress signals during fetal or early postnatal periods may disorganize reproductive axis development at different levels. This study was aimed to test the hypothesis that prenatal immunological stress induced by bacterial endotoxin, lipopolysaccharide (LPS), has impact on structure and function of the reproductive system in female offspring. Adult female Wistar rats were divided into two groups, a control group (n = 5) and a LPS group (n = 12). Rats were injected with LPS 50 μg/kg body or 0.9% saline intraperitoneally on the 12th day of pregnancy. After birth the female pups (n = 20 in each group) were divided into four groups: (group 1) 0.9% saline prenatally, sesame oil (vehicle) postnatally; (group 2) LPS prenatally, sesame oil postnatally; (group 3) LPS prenatally, fulvestrant postnatally; (group 4) LPS prenatally, flutamide postnatally. Pups were injected subcutaneously into the neck with fulvestrant (estrogen receptor antagonist), 1.5 mg/kg in sesame oil, from postnatal day (PND) 5 to PND14; or flutamide (androgen receptor antagonist), 20 mg/kg in sesame oil, from PND14 to PND30. Rats of the control group were injected with sesame oil during the same time period. Parameters were evaluated by ELISA (serum estradiol and testosterone) and ovarian histology. The main findings were: (1) prenatal stress during the critical period resulted in delayed vaginal opening, decreased body weight and serum concentrations of sex steroids, and significant disorders in ovarian development; (2) postnatal estradiol and testosterone antagonist treatments decreased follicular atresia through increasing the number of healthy follicles and restored endogenous steroid production. Lay summaryImmunological stress, caused by simulating infection through exposure to a bacterial toxin (LPS), during a critical period of fetal development in laboratory rats results in delayed reproductive maturity, decreased body weight and decreased secretion of sex steroids in female offspring, and abnormalities in the ovaries like those in polycystic ovarian syndrome. These prenatally toxin-induced sexual disorders in females could be corrected by estradiol/testosterone antagonists during the postnatal period.

Abstract
Polycystic ovary syndrome (PCOS), a major endocrinopathy is associated with barrage of metabolic aberrations. Reports in literature on association of PCOS and autoimmunity are conflicting. We aim to evaluate serum levels of anti-nuclear antibody (ANA) among Indian women with PCOS. In this hospital-based single center cross-sectional study, women qualifying a diagnosis of PCOS by Rotterdam criteria 2003 were recruited. Eighty-nine eligible women who consented were enrolled. All these women along with 87 age-matched, healthy controls underwent, clinical (menstrual history, anthropometry, hirsutism scoring), biochemical, hormonal assessment and serum ANA estimation. OGTT after overnight (8-12 h) fast with 75 g oral glucose load was done for 1 h, 2 h glucose and insulin measurements. The mean age of cases and controls was comparable (22.67 ± 5.53 vs. 22.84 ± 3.64 years). The prevalence of ANA positivity was significantly higher among women with PCOS (18.4% vs. 2.29%; p < .001). Though significant correlation was observed between ANA positivity and clinical signs of hyperandrogenism and plasma glucose, no significant correlation was noted between ANA status and other hormonal parameters. Higher prevalence of ANA positivity among women with PCOS, being a marker of autoimmunity, suggests a possible role of autoimmunity in causation of PCOS and needs further elucidation.

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
Polycystic ovarian syndrome (PCOS) is a low-grade inflammatory disease characterized by hyperandrogenism and ovarian hyperinnervation. The aim of this work is to investigate whether in vivo bilateral superior ovarian nerve (SON) section in adult rats with estradiol valerate-induced PCOS (PCO rats) affects macrophage spleen cells (MФ) and modifies the steroidogenic ability of their secretions. Culture media of MФ from PCO rats and PCO rats with SON section (PCO-SON rats) were used to stimulate in vitro intact ovaries. Compared with macrophages PCO, macrophages from PCO-SON rats released less tumor necrosis factor-α and nitric oxide, expressed lower Bax and Nfkb mRNA and showed reduced TUNEL staining. Also, in PCO rats, the SON section decreased kisspeptin and nerve growth factor mRNA expressions, without changes in Trka receptor mRNA levels. Macrophage secretions from PCO-SON rats decreased androstenedione and stimulated progesterone release in PCO ovaries, compared to macrophage secretions from PCO rats. No changes were observed in ovarian estradiol response. These findings emphasize the importance of the SON in spleen MΦ, since its manipulation leads to secondary modifications of immunological and neural mediators, which might influence ovarian steroidogenesis. In PCO ovaries, the reduction of androstenedione and the improvement of progesterone release induced by PCO-SON MΦ secretion, might be beneficial considering the hormonal anomalies characteristic of PCOS. We present functional evidence that modulation of the immune-endocrine function by peripheral sympathetic nervous system might have implications for understanding the pathophysiology of PCOS.

Abstract
BACKGROUND To our knowledge, no reports are available indicating the effects of synbiotic supplementation on hormonal status, biomarkers of inflammation and oxidative stress in subjects with polycystic ovary syndrome (PCOS). This research was done to assess the effects of synbiotic supplementation on hormonal status, biomarkers of inflammation and oxidative stress in subjects with PCOS. METHODS This randomized double-blind, placebo-controlled trial was conducted on 60 subjects diagnosed with PCOS according to the Rotterdam criteria. Subjects were randomly assigned into two groups to take either synbiotic (n = 30) or placebo (n = 30) for 12 weeks. Endocrine, inflammation and oxidative stress biomarkers were quantified at baseline and after the 12-week intervention. RESULTS After the 12-week intervention, compared with the placebo, synbiotic supplementation significantly increased serum sex hormone-binding globulin (SHBG) (changes from baseline in synbiotic group: + 19.8 ± 47.3 vs. in placebo group: + 0.5 ± 5.4 nmol/L, p = 0.01), plasma nitric oxide (NO) (changes from baseline in synbiotic group: + 5.5 ± 4.8 vs. in placebo group: + 0.3 ± 9.1 μmol/L, p = 0.006), and decreased modified Ferriman Gallwey (mF-G) scores (changes from baseline in synbiotic group: - 1.3 ± 2.5 vs. in placebo group: - 0.1 ± 0.5, p = 0.01) and serum high-sensitivity C-reactive protein (hs-CRP) (changes from baseline in synbiotic group: - 950.0 ± 2246.6 vs. in placebo group: + 335.3 ± 2466.9 ng/mL, p = 0.02). We did not observe any significant effect of synbiotic supplementation on other hormonal status and biomarkers of oxidative stress. CONCLUSIONS Overall, synbiotic supplementation for 12 weeks in PCOS women had beneficial effects on SHBG, mFG scores, hs-CRP and NO levels, but did not affect other hormonal status and biomarkers of oxidative stress.

Abstract
Chronic low-grade inflammation has been suggested as a key contributor of the pathogenesis and development of polycystic ovary syndrome (PCOS). To investigate the association between oxidative stress status and inflammatory cytokines in follicular fluid of 21 PCOS women compared to 21 women with normal ovarian function who underwent intra-cytoplasmic sperm injection. Concentration of IL-6, IL-8, IL-10, and TNF-α was measured using sandwich ELISA. Oxidative stress was examined by measuring total oxidant status (TOS), malondialdehyde (MDA), total antioxidant capacity (TAC), and thiol groups. PCOS women had an elevated concentration of MDA and TOS compared to controls. Levels of TAC and thiol groups were lower in PCOS compared to controls. PCOS patients had a higher concentration of IL-6, IL-8, and TNF-α compared to controls. Concentration of IL-10 was lower in PCOS compared to controls. Significant correlations were found between MDA and TOS concentration with TNF-α and between IL-6 and MDA, IL-8 and TAC, IL-10 and TOS levels and also between IL-10 and TAC levels. TAC and thiol groups were negatively correlated with TNF-α. Increased oxidative stress in PCOS is associated with inflammation which is closely linked. Inflammation can induce production of inflammatory cytokines in this syndrome and directly stimulates excess ovarian androgen production.

Abstract
BACKGROUND Chronic activation of macrophage-mediated inflammatory signals in insulin-sensitive metabolic tissues is thought to be one of the causes of insulin resistance-one of the hallmarks of the metabolic syndrome. Insulin resistance is a feature of polycystic ovary syndrome (PCOS) and is related to mitochondrial and endothelial function. METHODS In the present study, we investigated the phosphorylation level of FoxO 1, which is suppressed by the action of AKT, triggers the TLR4 inflammatory signaling pathway in the macrophages, from polycystic ovary syndrome patients or normal subjects. Then we investigated the influence of phosphorylation level of FoxO 1FoxO 1 on the induction of proinflammatory cytokines in the macrophages and the influence by FoxO FoxO 1 knockdown on the insulin-induced glucose uptake in PCOS macrophages. RESULTS Our results demonstrated that the significantly high level of FoxO 1FoxO 1 phosphorylation correlated with the production of proinflammatory cytokines, such as IL-6, IL-1β, and TNF-α in the macrophages from PCOS patients. The high level of FoxO 1FoxO 1 phosphorylation enhanced the TLR-4 signaling in response to LPS, and the FoxO FoxO 1 knockdown inhibited the insulin-induced glucose uptake in PCOS macrophages. CONCLUSIONS The findings of this paper suggest an intriguing regulatory transcriptional/signaling loop in macrophages that may contribute to maintain and exacerbate inflammation and insulin resistance in PCOS macrophages.

Abstract
Obesity is a major factor in development of insulin resistance (IR) and metabolic features in polycystic ovary syndrome (PCOS) patients. Nearly two-thirds patients with PCOS (30 of 37 confirmed cases of PCOS) in our previous community based study were lean, in contrast to Caucasians. Metabolic parameters including IR and β cell function have not been characterized well in this group of lean PCOS. To study the metabolic features including IR and β cell function in lean PCOS patients, 53 patients with BMI, <23 kg/m2 were compared with 71 obese PCOS and 45 age and body mass index matched controls. Lean patients had similar β cell function and IR as compared to controls and obese patients, though the latter group had more metabolic abnormality. Fasting c-peptide and its ratio to glucose were significantly higher in lean patients compared to controls. In subset of subjects with five point OGTT, disposition index and Matsuda index (MI) showed significant negative correlation with BMI and blood pressure. MI also negatively correlated with waist, WHR, and HOMAB. High fasting C-peptide is probably a class effect as is seen in both lean and obese PCOS.

Abstract
It has been shown that serum homocysteine (Hcy) levels are higher in women with polycystic ovary syndrome (PCOS). However, the specific role of hyperhomocysteinemia (HHcy) in the development of PCOS has never been reported. Adipose tissue inflammation is featured by the infiltration of macrophages, which plays a critical role in the pathogenesis of glucose and insulin intolerance. In this study, C57BL/6 mice were treated with dehydroepiandrosterone (DHEA) and/or a high methionine diet to induce PCOS and HHcy mice models. We showed that DHEA induced a PCOS-like phenotypes, irregular estrous cycles, weight gain, abnormal sex hormone production, glucose and insulin resistance, and polycystic ovaries. HHcy further intensified the effects DHEA on the metabolic, endocrinal, hormonal, and morphological changes in PCOS-like mice. In addition, HHcy attenuated the DHEA-induced increase in serum estrogen levels in mice. Furthermore, HHcy may exacerbate the insulin resistance in PCOS-like mice, most likely through modulating the macrophage M1/M2 polarization pathways via the suppression of estrogen. Most important, our clinical data showed that there were increases in serum Hcy levels in patients with PCOS. These findings deepen our understanding of the pathological roles of HHcy in the development of PCOS and provide a promising target for PCOS therapy in clinical application.

Abstract
PURPOSE Polycystic ovary syndrome (PCOS) affects quality of life and can worsen anxiety and depression either due to the features of PCOS or due to the diagnosis of a chronic disease. Corticotrophin-releasing hormone (CRH) and nerves growth factor (NGF) are the modulator for the actions of the sympathetic nervous and immune systems. METHODS In total, 171 women divided into two groups: study and control groups. Serum CRH, NGF, and interleukins: IL-1α. IL-1β, 17A, and TNFα were determined by ELISA Kits in both groups. RESULTS The results showed that IL-1α (p < 0.001) and β (p = 0.017) significantly increased in PCO group. CRH, NGF, and IL-17α in serum of patients with PCO significantly lower than the control group (p < 0.001). The results of this study indicate: (1) destruction of three cytokines pattern, (2) Reduction of CRH, NGF, and IL-17α in serum of PCO patients can be under the direct influence of the sympathetic nervous system (SAS), and (3) reduction of CRH and NGFα can be reason of psych/emotional distress in women with PCOS. CONCLUSIONS The results of this study confirm (1) low-grade chronic inflammation in PCOS. This impaired cytokine pattern can play a major role in the immune-pathogenesis of PCOS; (2) hyponeurotrophinemia and reduction of CRH in women with PCOS could reflect deficit of neuronal stress-adaptation in these patients.

Abstract
Polycystic ovary syndrome is a disorder which affects 5-10% of women in reproductive age. PCOS is a cause of hyperandrogenism, menstrual disorders and infertility. The most common clinical symptoms are hirsutism, acne and obesity. Patients often suffer from metabolic disorders: insulin resistance, hyperinsulinemia, dislipidemia, leading to atherosclerosis and others irregularities of the metabolic syndrome. Patients are in the high risk group for cardiovascular diseases (CVD) development because of the metabolic abnormalities. Obesity is observed in 35-60% of women with PCOS. Lean women with PCOS are also exposed to a greater risk of glucose intolerance development and abnormalities in lipid profile than women without PCOS with comparable BMI. Adipocytes are the source of many compounds of the paracrine and endocrine activity. Some of them are also markers and mediators of inflammation. Increased levels of proinflammatory cytokines in blood can promote atherosclerosis and cardiovascular disease. Markers: IL-18, TNF, IL-6 and hs-CRP are often elevated in patients with polycystic ovary syndrome. An increase in inflammatory markers may be an early indicator of the risk of developing insulin resistance and atherosclerosis, and may become a useful prognostic and therapeutic tool for monitoring patients with PCOS: lean and those with overweight and obesity. Assessment of the concentrations of inflammatory markers may become a very useful test in evaluating the risk of developing atherosclerosis and cardiovascular disease, long before their clinical manifestation. It will also allow for the appropriate prophylaxis.

Abstract
CONTEXT Polycystic ovarian syndrome (PCOS), the most common endocrine disorder of reproductive-aged women, is associated with systemic low-grade inflammation. OBJECTIVE We propose that increased or altered intrafollicular inflammatory reactions also occur in periovulatory follicles of PCOS patients. DESIGN Gene profiling and quantitative PCR (qPCR) analyses in granulosa-lutein cells (GCs) collected from PCOS and non-PCOS women undergoing in vitro fertilization were compared with serum and follicular fluid (FF) levels of cytokines and chemokines. SETTING This was a university-based study. PATIENTS Twenty-one PCOS and 45 control patients were recruited: demographic, hormone, body mass index, and pregnancy outcomes were abstracted from patient data files. INTERVENTIONS GC cytokine/chemokine mRNAs were identified and analyzed by gene-chip microarrays/qPCR before and after culture with human chorionic gonadotropin, DHT, IL-6, or IL-8; serum/FF cytokine levels were also analyzed. MAIN OUTCOME MEASURES Relative serum/FF cytokine levels and GC cytokine expression before and after culture were compared and related to body mass index. RESULTS The following results were found: 1) PCOS GCs express elevated transcripts encoding cytokines, chemokines, and immune cell markers, 2) based on gene profiling and qPCR analyses, obese PCOS patients define a distinct PCOS disease subtype with the most dramatic increases in proinflammatory and immune-related factors, and 3) human chorionic gonadotropin and DHT increased cytokine production in cultured GCs, whereas cytokines augmented cytokine and vascular genes, indicating that hyperandrogenism/elevated LH and obesity in PCOS women augment intrafollicular cytokine production. CONCLUSIONS Intrafollicular androgens and cytokines likely comprise a local regulatory loop that impacts GC expression of cytokines and chemokines and the presence of immune cells; this loop is further enhanced in the obese PCOS subtype.

Abstract
Low 25(OH) vitamin D levels have been associated with several autoimmune diseases and recently with autoimmune thyroid disease (AITD). The aim of the study was to investigate the association of AITD with 25(OH) vitamin D levels in women with polycystic ovary syndrome (PCOS). Fifty women with PCOS were consecutively enrolled and underwent routine health checkups, which included measurements of 25(OH) vitamin D, anti-thyroid peroxidase (TPO-Ab), anti-thyreoglobulin (TG-Ab) antibodies, FT3, FT4, and TSH. Selecting 50 nmol/L as cut-off point, low 25(OH) vitamin D levels were detected in 23 of 50 patients (46 %). AITD was diagnosed when TPO-Ab levels exceeding 80 U/ml and/or TG-Ab levels exceeding 70 U/ml. AITD was detected in 12 of 50 patients (24 %). The levels of 25(OH) vitamin D were significantly lower in women with PCOS and AITD when compared with women with PCOS and without AITD (p = 0.02). In women with AITD no correlation was found between 25(OH) vitamin D and TG-Ab (r = 0.48; p = 0.16), TPO-Ab (r = 0.43; p = 0.21), TSH (r = 0.38; p = 0.27), FT3 (r = -0.40; p = 0.25) and FT4 levels (r = -0.54; p = 0.10). These findings suggest that low levels of 25(OH) vitamin D were significantly associated with AITD in women with PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is a leading cause of anovulatory infertility. In recent times, autoimmune processes are supposed to play a role in a number of conditions with unexplained etiology. This includes some cases of human infertility. The attempts to detect antiovarian antibodies in patients with PCOS generally produced negative results. Presence of non-organ specific autoantibodies in patients with polycytosis has been reported, but the data are till inconsistent. Meanwhile, a number of recent sludies reveal a correlation between PCOS, hypothyroidism (manifested or subclinical) and autoimmunity. In this respect, many authors recommend thyroid function to be regularly checked in patients with PCOS. There are data that certain categories of women with polycystosis show an elevated concentration of antisperm antibodies. The problem is an interesting example how a pathological process can elucidate the complex interactions between the immune system and various compartments of the endocrine system that include immunologically isolated antigens.

Abstract
UNLABELLED Polycystic ovary syndrome (PCOS) is a heterogeneous and complex endocrine disease which among the female population belongs to the most widespread endocrinopathies and it is the most frequent cause of hyperthyroidism, anticoagulation and infertility. Insulin resistance is one of the important diabetology factors impacting hyperglycaemia in a majority of women with PCOS (60-80 %). Clinical expressions of PCOS include reproduction disorders, metabolic characteristics and psychological implications. Reproduction disorders include hyperthyroidism, menstruation cycle disorders, infertility and pregnancy complications as well as early abortions, gestational diabetes and pregnancy induced hypertension. Long-term metabolic risks of PCOS include type 2 diabetes mellitus, dyslipidemia, arterial hypertension and endothelial dysfunction. The available data confirms higher incidence of cardiovascular diseases in women with PCOS. In particular among obese women PCOS is more frequently associated with non-alcoholic hepatic steatosis, sleep apnoea syndrome and endometrial cancer. The literature includes some controversial data about the relationship between PCOS and autoimmunity. Women with PCOS are more prone to suffer from insufficient confidence with higher incidence of anxiety, depression, bipolar disorder and eating disorders. KEY WORDS autoimmunity - diabetes mellitus - pregnancy - insulin resistance - metabolic syndrome - menstrual disorders - polycystic ovary syndrome.

Abstract
OBJECTIVE Immune dysregulation may play an important role in the pathogenesis of polycystic ovary syndrome (PCOS). The purpose of this study was to investigate the Th1 and Th2-related cytokine profile in local ovary of women with PCOS. STUDY DESIGN The T lymphocytes of follicular fluid (FF) were obtained at the time of oocyte retrieval before in-vitro fertilization (IVF) in woman with or without PCOS. After culturing with PMA, Ionomycin and Golgi stop agent, cells were detected for the intracellular cytokine production by flow cytometry. The profile of Th1 (IFN-γ, IL-2) and Th2 (IL-4, IL-10) cytokines of CD3(+) CD4(+)T lymphocyte subsets were analyzed through invert gating. These cytokines in FF were also evaluated by ELISA. RESULTS Flow cytometry analysis showed that the production of Th1 (IFN-γ, IL-2) cytokines in FF lymphocytes in PCOS patients were significantly higher than those in controls; ELISA result also demonstrated that the concentration of Th1 cytokines (IFN-γ, IL-2) in FF in PCOS patients is significantly increased compared with those in controls. CONCLUSION It is concluded that the immune dominance of Th1 may be the immunological feature of the ovary in PCOS patients. It might participate in the immune pathogenesis in the ovary of PCOS patients. These results suggest that chronic inflammation maybe one of the underlying mechanism for the pathogenesis of PCOS.

Abstract
OBJECTIVE The objective of this study was to determine the levels of thrombospondin-1 (TSP-1), transforming growth factor-β1 (TGF-β1) and nuclear factor kappaβ (NF-κβ) in polycystic ovarian syndrome (PCOS) patients with and without insulin resistance and after treatment with cyproterone acetate/ethinyloestradiol with or without concomitant metformin. DESIGN Prospective. PATIENTS Patients with PCOS and healthy women were recruited. Patients were subdivided into obese and nonobese based on body mass index. Patients with PCOS were also grouped according to homoeostasis model assessment-insulin resistance (HOMA-IR) ≥ 2·69 or <2·69, and by PCOS phenotype. Patients with PCOS-IR were treated with a 6-month course of cyproterone acetate/ethinyloestradiol with or without concomitant metformin. MEASUREMENTS Inflammatory markers were examined at baseline, and after 6 months of treatment. RESULTS A total of 445 women with PCOS (mean age 25·9 ± 2·7 years; 298 obese, 147 nonobese) and 213 normal controls (mean age 24·9 ± 3·0 years) were included. Regardless of obesity status, testosterone, free androgen index (FAI), luteinizing hormone/follicle-stimulating hormone (LH/FSH) ratio, HOMA-IR, TSP-1 and NF-κB in the PCOS groups were significantly higher than in the control group, whereas TSP-1 was lower in the PCOS groups (all, P < 0·05). Patients with PCOS without IR had lower TSP-1 levels than control patients (P < 0·05). Treatment with cyproterone acetate/ethinyloestradiol with addition of metformin reduced the level of NF-κB, TGF-β1 and HOMA-IR and increased the level of TSP-1. CONCLUSIONS These results support the association between PCOS and chronic inflammation.

Abstract
CONTEXT It is now clear that oxidative stress (OS) and chronic low-grade inflammation are two main pathways involved in polycystic ovary syndrome (PCOS) pathogenesis. Therefore, simultaneous targeting of these pathways by means of carvedilol and Semelil (ANGIPARS™), as established medicines with dual anti-cytokine and anti-oxidant potential may be a therapeutic alternative approach to the current treatments. OBJECTIVE The objective of this study is to study the protective effects of carvedilol and ANGIPARS™ on inflammatory and oxidative response in hyperandrogenism-induced polycystic ovary (PCO). MATERIALS AND METHODS The murine model of PCO was induced by letrozole (1 mg/kg/d; orally) and effective doses of carvedilol (10 mg/kg/d; orally) and ANGIPARS™ (2.1 mg/kg/d; orally) were administrated for 21 d in PCO and non-PCO healthy rats. Ovarian folliculogenesis, sex hormones concentrations, OS, inflammatory, and metabolic biomarkers were assessed in serum and ovaries. RESULTS PCO rats exhibited ovarian cystogenesis which was preserved by the application of carvedilol and ANGIPARS™. In comparison with controls, decreased level of the total antioxidant power (TAP) and higher levels of reactive oxygen species (ROS) and lipid peroxidation (LPO) in serum and ovaries (2.41 ± 0.67 versus 0.72 ± 0.11; and 0.17 ± 0.04 versus 0.05 ± 0.01; 5.48 ± 1.30 versus 10.56 ± 0.77; and 7.06 ± 1.94 versus 17.98 ± 0.98; p < 0.05, respectively) were detected in PCO rats. Moreover, the PCO rats exhibited hyperandrogenism due to a 3.7-fold increase in serum testosterone concentration (35.04 ± 3.17 versus 131.09 ± 13.24; p < 0.05) along with a 2.98-fold decrease in serum progesterone (6.19 ± 0.40 versus 18.50 ± 1.03; p < 0.05) and 5.2-fold decrease in serum estradiol (9.30 ± 0.61 versus 48.3 ± 2.10; p < 0.05) when compared with those of the control group. However, similar to the control group, normal levels of OS markers and sex hormones were detected in ANGIPARS™ and carvedilol co-treated PCO rats. Besides, when compared with controls, increased levels of TNF-α (770.75 ± 42.06 versus 477.14 ± 28.77; p < 0.05) and insulin (1.27 ± 0.10 versus 0.36 ± 0.05; p < 0.05) in PCO rats were significantly inhibited by carvedilol and ANGIPARS™ co-treatment. DISCUSSION AND CONCLUSION We evidenced the beneficial effects of carvedilol and ANGIPARS™ in PCO, which underpin the new alternative approach in using these kinds of medicines in female reproductive disorders.

Abstract
In polycystic ovary syndrome (PCOS), oxidative stress is implicated in the development of β-cell dysfunction. However, the role of mononuclear cell (MNC)-derived inflammation in this process is unclear. We determined the relationship between β-cell function and MNC-derived nuclear factor-κB (NF-κB) activation and tumor necrosis factor-α (TNF-α) secretion in response to a 2-h 75-g oral glucose tolerance test (OGTT) in normoglycemic women with PCOS (15 lean, 15 obese) and controls (16 lean, 14 obese). First- and second-phase β-cell function was calculated as glucose-stimulated insulin secretion (insulin/glucose area under the curve for 0-30 and 60-120 min, respectively) × insulin sensitivity (Matsuda Index derived from the OGTT). Glucose-stimulated NF-κB activation and TNF-α secretion from MNC, and fasting plasma thiobarbituric acid-reactive substances (TBARS) and high-sensitivity C-reactive protein (hs-CRP) were also assessed. In obese women with PCOS, first- and second-phase β-cell function was lower compared with lean and obese controls. Compared with lean controls, women with PCOS had greater change from baseline in NF-κB activation and TNF-α secretion, and higher plasma TBARS. β-Cell function was inversely related to NF-κB activation (1st and 2nd) and TNF-α secretion (1st), and plasma TBARS and hs-CRP (1st and 2nd). First- and second-phase β-cell function also remained independently linked to NF-κB activation after adjustment for body fat percentage and TBARS. In conclusion, β-cell dysfunction in PCOS is linked to hyperglycemia-induced NF-κB activation from MNC and systemic inflammation. These data suggest that in PCOS, inflammation may play a role in impairing insulin secretion before the development of overt hyperglycemia.

Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) has been associated with an autoimmune origin, either per se or favoring the onset of autoimmune diseases, from a stimulatory action on the inflammatory response. Thus, autoimmune thyroiditis (AIT) could be more prevalent among women with PCOS. OBJECTIVE To evaluate the prevalence of AIT in women with PCOS. STUDY DESIGN It was a cross-sectional study, in a tertiary center, including 65 women with PCOS and 65 women without this condition. Clinical and laboratory parameters were evaluated and a thyroid ultrasound scan was performed. Levels of thyroid-stimulating hormone (TSH), free thyroxine (FT4), free triiodothyronine (FT3), anti-thyroid peroxidase (anti-TPO) antibodies, anti-thyroglobulin (anti-TG) antibodies, and thyroid ultrasound findings were evaluated. RESULTS The prevalence of subclinical hypothyroidism (SCH) in women with PCOS was 16.9% and 6.2% in the non-PCOS group. AIT was more common in the PCOS group compared with the non-PCOS group (43.1% versus 26.2%). But, when it was adjusted by weight and insulin resistance, the difference in the thyroiditis risk was not observed (OR 0.78, CI 0.28-2.16). CONCLUSION AIT risk was similar in the PCOS and the non-PCOS group. SCH are more common in women with PCOS, highlighting a need for periodic monitoring of thyroid function.

Abstract
OBJECTIVES The objective of this study is to investigate plasma endogenous thrombin generation in four different phenotypes of polycystic ovary syndrome (PCOS) defined by Body Mass Index (BMI) and insulin resistance (IR). PCOS is diagnosed according to the Rotterdam criteria. DESIGN Multicenter cross-sectional study. SETTING Two major University Hospitals in the Capital region of Denmark. PATIENTS Hundred forty-eight European women with PCOS were consecutively recruited during April 2010-February 2012. Clinical examination, blood sampling, and DEXA scan were performed. MAIN OUTCOME MEASURES Endogenous thrombin potential (ETP). RESULTS PCOS women with phenotype BMI > 25 + IR have increased potential of thrombin generation. ETP is associated with total body fat mass, IR, and CRP. CONCLUSIONS Obese and insulin resistant women with PCOS have elevated level of ETP corresponding to increased risk of CVD. ETP is related to well-known CVD risk factors in PCOS but not in general to the Rotterdam criteria.

Abstract
CONTEXT The immunesupressive action of CD4(+)CD25(+) CD127(-/low) T regulatory cells (Tregs) is vital for an efficient reproductive function. However no data exists on their number or functionality in polycystic ovary syndrome (PCOS). OBJECTIVE The study aimed to analyze the frequency of circulating Tregs and key factors modulating them in women with PCOS. DESIGN, SETTING, AND PARTICIPANTS This is a retrospective, case-control cohort study conducted in women with PCOS recruited from Samad IVF hospitals and Women and Children Hospital, Thiruvananthapuram, India. Women with PCOS (N = 20) were diagnosed according to Rotterdam Consensus and normal menstruating women were taken as controls (N = 2331). MAIN OUTCOME MEASURES We analyzed the proportion of CD4(+)CD25(+) CD127(-/low) Tregs in women with PCOS by fluorescent activated cell sorting. RESULTS The study discovered that the women with PCOS have reduced numbers of Tregs (2.626 ± 0.62) compared with controls (4.253 ± 0.87) (t = 6.963, P < .0001, mean difference = -1.627; 95% confidence interval = -2.099--1.155). We documented a decrease in the follicular phase Treg expansion in women with PCOS. Our results revealed a reduced STAT5A (fold change [FC] = 7.642, P < .0004)/STAT5B (FC = 3.824, P < .0001), FOXP3 (FC = 4.1343, P = .0004)/CTLA4 (FC = 2.569, P = .0001) and elevated AKT (FC = 7.39, P = .05)/PIK3 (FC = 5.326, P = .0002) expression in women with PCOS. Recombinant interleukin 2 (rIL2) treatment failed to improve FOXP3/CTLA4 levels but caused a reduction of AKT/PIK3 arm, possibly due to an elevated PTEN in women with PCOS. CONCLUSION The study suggests that women with PCOS have reduced Tregs due to an inherent hyporesponsiveness to IL2, which is unable to activate STAT5B and reduce FOXP3 expression. IL2-based therapeutic strategies can ameliorate complications in PCOS by suppressing the AKT/PIK3 arm.

Abstract
OBJECTIVE We evaluated mononuclear cell (MNC) preactivation in women with polycystic ovary syndrome (PCOS) by examining the effect of in vitro lipopolysaccharide (LPS) exposure on cytokine release in the fasting state. STUDY DESIGN Twenty women with PCOS (10 lean, 10 obese) and 20 weight-matched controls (10 lean, 10 obese) volunteered for study participation. Tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) release was measured from mononuclear cells isolated from fasting blood samples and cultured in the presence and absence of LPS. Plasma IL-6 was measured from the same fasting blood samples. Insulin sensitivity was derived from an oral glucose tolerance test using the Matsuda index, and truncal fat was measured by dual-energy x-ray absorptiometry. RESULTS The percent change from baseline in TNF-α and IL-6 release from MNC following LPS exposure was increased (P < .04) in lean and obese women with PCOS and obese controls compared with lean controls. Plasma IL-6 was increased (P < .02) in obese women with PCOS compared with lean women with PCOS, which in turn was increased (P < .02) compared with lean controls. The MNC-derived TNF-α and IL-6 responses from MNCs were negatively correlated with insulin sensitivity (P < .03) and positively correlated with testosterone (P < .03) and androstenedione (P < .006) for the combined groups. Plasma IL-6 was positively correlated with percentage truncal fat (P < .008). CONCLUSION In PCOS, increased cytokine release from MNCs following LPS exposure in the fasting state reveals the presence of MNC preactivation. Importantly, this phenomenon is independent of obesity and may contribute to the development of insulin resistance and hyperandrogenism in PCOS. In contrast, the source of plasma IL-6 elevations in PCOS may be excess adiposity.

Abstract
CONTEXT Excess adipose tissue is a source of inflammation. Polycystic ovary syndrome (PCOS) is a proinflammatory state and is often associated with excess abdominal adiposity (AA) alone and/or frank obesity. OBJECTIVE To determine the effect of glucose ingestion on cytokine release from mononuclear cells (MNC) in women with PCOS with and without excess AA and/or obesity. DESIGN A cross-sectional study. SETTING Academic medical center. PATIENTS Twenty-three women with PCOS (seven normal weight with normal AA, eight normal weight with excess AA, eight obese) and 24 ovulatory controls (eight normal weight with normal AA, eight normal weight with excess AA, eight obese). INTERVENTION Three-hour 75-g oral glucose tolerance test (OGTT). MAIN OUTCOME MEASURES Body composition was measured by dual energy x-ray absorptiometry. Insulin sensitivity was derived from the OGTT (ISOGTT). TNFα, IL-6, and IL-1β release was measured in supernatants of cultured MNC isolated from blood samples drawn while fasting and 2 hours after glucose ingestion. RESULTS Insulin sensitivity was lower in obese subjects regardless of PCOS status and in normal-weight women with PCOS compared with normal-weight controls regardless of body composition status. In response to glucose ingestion, MNC-derived TNFα, IL-6, and IL-1β release decreased in both normal-weight control groups but failed to suppress in either normal-weight PCOS group and in obese women regardless of PCOS status. For the combined groups, the cytokine responses were negatively correlated with insulin sensitivity and positively correlated with abdominal fat and androgens. CONCLUSIONS Women with PCOS fail to suppress MNC-derived cytokine release in response to glucose ingestion, and this response is independent of excess adiposity. Nevertheless, a similar response is also a feature of obesity per se. Circulating MNC and excess adipose tissue are separate and distinct sources of inflammation in this population.

Abstract
Polycystic ovary syndrome (PCOS) is a hormonal disorder of women that not only is the leading cause of infertility but also shows a reciprocal link with oral health. This study aimed to investigate the hypothesis that the levels of putative periodontal pathogens in saliva and their antibody response in serum are elevated in PCOS, compared to systemic health. A total of 125 women were included in four groups; 45 women with PCOS and healthy periodontium, 35 women with PCOS and gingivitis, 25 systemically and periodontally healthy women, 20 systemically healthy women with gingivitis. Salivary levels of seven putative periodontal pathogens were analyzed by quantitative real-time polymerase chain reaction and serum antibody levels were analyzed by ELISA. In women with PCOS, salivary Porphyromonas gingivalis, Fusobacterium nucleatum, Streptococcus oralis and Tannerella forsythia levels were higher than matched systemically healthy women, particularly in the case of gingivitis. Aggregatibacter actinomycetemcomitans and Treponema denticola levels were similar among study groups. The presence of PCOS also enhanced P. gingivalis, Prevotella intermedia and S. oralis serum antibody levels, when gingivitis was also present. Gingival inflammation correlated positively with levels of the studied taxa in saliva, particularly in PCOS. The presence of P. gingivalis and F. nucleatum in saliva also exhibited a strong positive correlation with the corresponding serum antibody levels. In conclusion, as an underlying systemic endocrine condition, PCOS may quantitatively affect the composition of oral microbiota and the raised systemic response to selective members of this microbial community, exerting a confounding role in resultant gingival inflammation and periodontal health. The most consistent effect appeared to be exerted on P. gingivalis.

Abstract
CONTEXT It is believed that a dysfunction in adipose tissue plays an important role in the pathogenesis of polycystic ovary syndrome (PCOS). Natriuretic peptides are hormones that regulate cardiovascular and body fluid homeostasis and adipose tissue metabolism. Natriuretic peptide levels are reduced in individuals with obesity and diabetes. OBJECTIVE This study aimed to investigate whether natriuretic peptide levels are altered in women with PCOS and whether they correlate with adiponectin levels or insulin sensitivity markers. DESIGN AND SETTING This was a cross-sectional study at a referral center in a teaching hospital. PATIENTS OR OTHER PARTICIPANTS We evaluated 40 patients diagnosed with PCOS according to the Rotterdam criteria and 36 control women matched for age and body mass index. MAIN OUTCOME MEASURES We measured serum adiponectin, plasma atrial natriuretic peptide (ANP), and plasma brain natriuretic peptide using enzyme immunoassays in both groups. We evaluated metabolic markers, such as fasting glucose, insulin, total cholesterol, high-density lipoprotein, low-density lipoprotein, and triglycerides. In addition, we calculated the homeostasis model assessment for insulin resistance index (HOMA-IR) and the lipid accumulation product (LAP) index and tested the linear correlations between these metabolic indices and the plasma ANP and serum adiponectin concentrations. RESULTS ANP and adiponectin were reduced in the PCOS group compared with the control group (P = 0.010 and P = 0.014, respectively). The brain natriuretic peptide concentration did not differ between the two groups (P = 0.883). There was no correlation between ANP and any of the metabolic markers. In the control group, the serum adiponectin level was inversely correlated with BMI (P = 0.011), waist circumference (P = 0.021), insulin (P = 0.013), fasting glucose (P = 0.010), homeostasis model assessment for insulin resistance index (P = 0.007), and lipid accumulation product (P = 0.022). Remarkably, none of these correlations were observed in the women with PCOS. CONCLUSION Women with PCOS had lower ANP and adiponectin compared with controls matched for age and BMI. Thus, the mechanisms that affect ANP and adiponectin production and clearance may be altered in PCOS, regardless of adiposity. These hormones may be involved in the metabolic features of PCOS.

Abstract
CONTEXT Statins have been shown to improve hyperandrogenism in women with polycystic ovary syndrome (PCOS). However, their use has also been associated with impairment of glucose metabolism and an increased risk of type 2 diabetes mellitus. Because women with PCOS are prone to disturbances in glucose metabolism, statin therapy could also have negative effects. OBJECTIVE Our objective was to explore the effects of atorvastatin therapy on hormonal and metabolic parameters in women with PCOS. DESIGN AND SETTING We conducted a randomized, double-blind, placebo-controlled 6-month follow-up study conducted at Oulu University Hospital, Finland. PATIENTS Women with PCOS (Rotterdam criteria) were treated with atorvastatin (20 mg/d, n = 15) or placebo (n = 13) for 6 months. INTERVENTIONS Fasting serum samples were collected at baseline and at 3 and 6 months. Oral and iv glucose tolerance tests were performed at 0 and 6 months. MAIN OUTCOME MEASURES Androgen secretion and glucose metabolism were measured. RESULTS Fasting levels and area under the curve of insulin increased significantly and insulin sensitivity (insulinogenic and Matsuda indexes) decreased during 6 months of atorvastatin therapy. Serum levels of dehydroepiandrosterone sulfate decreased in the atorvastatin group, whereas no change was observed in serum testosterone levels. Levels of C-reactive protein, total and low-density lipoprotein-cholesterol, and triglycerides decreased significantly during statin therapy. CONCLUSIONS Atorvastatin therapy improves chronic inflammation and lipid profile, but it impairs insulin sensitivity in women with PCOS. Because women with PCOS have an increased risk of developing type 2 diabetes mellitus, the results suggest that statin therapy should be initiated on the basis of generally accepted criteria and individual risk assessment of cardiovascular disease, and not only because of PCOS.

Abstract
UrotensinII (UII), one of the most potent vasoconstrictor proteins, may be associated with insulin resistance. The objective of our research was to determine the level of UII in sera of patients with PCOS and to investigate the relationship between UII and insulin resistance in patients with PCOS. Fourty seven PCOS patients and 42 healthy women were included in the study. Serum fasting glucose, insulin, UII, free testosterone and hs-CRP levels of the patients were examined. The HOMA-IR formula was used to calculate insulin resistance. Insulin sensitivity was calculated by using the QUICKI-IS formula. The two groups did not show any a significant difference in terms of age and BMI (p > 0.05). Serum UII, hs-CRP, insulin levels and the HOMA-IR were significantly higher in the patients with PCOS (p < 0.05). In the analysis of the correlation, UII and HOMA-IR showed statistically significant, moderately strong and positive correlation(r = 044, p < 0.001). UII and QUICKI-IS showed statistically significant, moderately strong and negative correlation(r = -0.44, p < 0.001). Also, a significant and positive correlation was found between with UII and hs-CRP(r = 0.51, p < 0.001). Our study data suggested that UII may have a role in the pathophysiology of insulin resistance and increased cardiovascular risk, which are commonly found in patients with PCOS.

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

Abstract
AIMS To investigate the relationship between the levels of C-reactive protein (CRP), interleukin-6 (IL-6) and IL-1β and the hormonal and metabolic alterations in women with polycystic ovary syndrome (PCO). MATERIALS AND METHODS Case-control study. CRP, IL-6 and IL-1β were evaluated in combination with obesity, insulin resistance (IR) and hyperandrogenism parameters in 20 patients with PCO. Twenty healthy women were used as the control. RESULTS The average CRP values was 5.1 in the cases vs. 0.8 mg/L in the control group (p < 0.0001). The IL-6 average values were 2.77 in the cases vs. 2.70 pg/ml in the control group (p = 0.254). IL-1β levels were found to be within the normal range in all individuals. A positive correlation was found between the CRP values and the IR (p < 0.0001) as well as with the presence of obesity (p < 0.02). No correlation was found between PCR and hyperandrogenemia (p = 0.4) nor between IL-6 values and IR (p = 0.3), or between the levels of this cytokine and the presence of hyperandrogenemia (p = 0.2). A significant correlation was found between IL-6 levels and obesity (p < 0.0001). CONCLUSIONS The present study demonstrates the presence of a chronic inflammation status in young women with PCO. These parameters are mainly related to obesity and, to a lesser extent, to IR.

Abstract
INTRODUCTION We aimed to determine the insulin resistance in women with PCOS patients who have normal oral glucose tolerance test (OGTT) and to evaluate cardiovascular risk by measuring C-reactive protein (CRP) and carotid intimae-media thickness (CIMT). METHODS A total of 34 patients and age and body mass matched 20 healthy control subjects were included to this prospective study. Both of patients and control groups were consisted of normal oral glucose tolerance test. Insulin resistance (IR) was estimated using HOMA-IR method. CRP, lipid and hormone levels were measured. CIMT was measured by Carotid Artery B-Mode ultrasonography. RESULTS There was no significant difference between patients and controls in BMI, and waist circumference, lipid, TSH, LH, FSH, estradiol, and prolactin levels. Serum insulin, testosterone, DHEAS, ferritin levels and HOMA values were significantly higher in patient group. We found that 64.7% (n = 22/34) patients with PCOS had insulin resistance. Both of CIMT and CRP levels were significantly higher in the PCOS patients had BMI over 25 kg/m². CRP levels was significantly higher in the PCOS patients had waist circumference greater than 80 cm. CONCLUSION We found insulin resistance in the women with PCOS even if OGTT was normal. Our data were similar to literature, the women with PCOS have increased risk of premature atherosclerosis and metabolic syndrome.

Abstract
Polycystic ovarian syndrome (PCOS) is an endocrine disorder affecting 5-10% of reproductive-age women. Hyperandrogenemia, which characterizes the syndrome, stimulates the maturation of adipocytes and favors central obesity. The linking hub between obesity and other metabolic manifestations of the syndrome seems to be chronic low-grade inflammation. We discuss the most reliable current data regarding the role of inflammatory mediators in PCOS, with particular focus on the genetic mechanisms implicated. C-reactive protein levels are 96% higher in PCOS patients than in healthy controls. Patients with the -308A polymorphism of the tumor necrosis factor-α gene have elevated androgens in comparison with carriers of the -308G. Interleukin 18 (IL-18) is elevated in lean patients, with a further rise in the presence of obesity and insulin resistance. Polymorphisms of the IL-1a, IL-1b and IL-6 genes have also been associated with PCOS. Plasminogen activator inhibitor-1 levels are positively associated with the syndrome, and carriers of the 4G allele of the 4G/5G polymorphism are at risk of developing PCOS. Other mediators discussed include adhesion molecules, osteoprotegerin, asymmetric dimethylarginine, homocysteine and advanced glycation end-products. The elucidation of the pathogenetic mechanisms implicated in PCOS and their connection with low-grade inflammation may in the future offer the opportunity for the formulation of novel therapeutic strategies and individualized therapy for these patients.

Abstract
BACKGROUND Several markers of low-grade chronic inflammation are altered in women with polycystic ovary syndrome (PCOS). Neopterin (NEO) is a marker of celullar immunity, and oxidative stress, mainly produced by activated macrophages. We aimed to evaluate the NEO levels in PCOS patients and correlate them with antropometric and biochemical parameters. METHODS The study groups consisted of 69 women with PCOS and 46 healthy controls. Both groups were divided into two subgroups according to their body mass index (BMI): <25 = normoweight, >25 = overweight. The clinical and biochemical parameters and serum NEO levels were analyzed. RESULTS Circulating levels of NEO were significantly (p < 0.001) higher in women with PCOS (normoweight: 15.9 ± 4.7 nmol/l; overweight 13.3 ± 8.1 nmol/l) compared to controls (normoweight: 8.6 ± 2.0 nmol/l; overweight 9.2 ± 1.8 nmol/l) regardless of their weight classes. Waist-to-hip ratio (WHR) (p < 0.05), free and total testosterone (p < 0.001) were significantly elevated in women with PCOS compared to controls after controlling for the effect of obesity. CONCLUSION Circulating NEO level s are elevated in PCOS independent of body mass index supporting the suggestion of PCOS is a low-grade chronic inflammatory state.

Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies in women of fertile age and lately there is a discussion about its possible association with autoimmune diseases. The aim of the study was to examine incidence of autoimmune thyreoiditis (AIT) in PCOS women. PATIENTS AND METHODS 64 PCOS patients were enrolled and 68 healthy menstruating women served as controls. All subjects were examined for thyrotropin (TSH), free thyroxin (fT4) and the presence as well as titers of antithyroid antibodies aTG (anti-thyreoglobulin) and aTPO (anti-thyreoperoxidase). RESULTS There was no difference between PCOS and controls in average TSH levels (2.37 ± 1.46 mIU/l vs 2.37 ± 1.46 mIU/l) (p = 0.953), and fT4 levels (16.36 ± 5.34 pmol/l vs 16.49 ± 2.32 pmol/l) (p = 0.852). Autoantibodies titers were also non-significant aTG (53.09 ± 157.07 IU/ml vs 29.8 ± 100.77 IU/ml, p = 0.386) and aTPO (59.74 ± 149.03 IU/ml vs 45 ± 204.77 IU/ml, p = 0.805). However, PCOS women had significantly higher prevalence of aTPO (18.75 vs 7.35%, p = 0.045). On the other hand, the overall prevalence of AIT was similar in both groups. CONCLUSION Our results show PCOS patients have slightly but significantly higher positivity of aTPO antibodies but the prevalence of AIT was insignificant.

Abstract
The aim of this study was to examine the effect of adrenal versus ovarian androgen (dehydroepiandrosterone sulfate/total testosterone [DHEAS/TT]) on clinical presentation and related metabolic disturbances in Turkish women with polycystic ovarian syndrome (PCOS). Two hundred eighty PCOS cases were taken into the study. For all cases, the DHEAS/TT ratio was calculated. The median value of this ratio was 4.40. Patients with an androgen ratio lower than 4.40 were included in Group 1 and cases with a ratio higher than 4.40 were Group 2. The two groups were compared in terms of hormonal, biochemical and clinical parameters. Body mass index and waist circumference were lower, the Ferriman-Gallwey score was higher and the cycle length was shorter in Group 2. High DHEAS level was associated with better lipid profiles and lower levels of inflammatory markers, meaning good metabolic control in these women, in spite of increased hirsutism rates. In patients with PCOS, both androgens are usually high in proportion to each other. Therefore, it would be more meaningful to use the DHEAS/TT ratio for an assessment of the metabolic and phenotypic effects of PCOS.
