Abstract Objectives There is a growing evidence indicating an impact of endocrine distrupting chemicals such as bisphenol A (BPA) on human reproduction. Its higher levels in serum or urine have been documented in women with polycystic ovary syndrome (PCOS), however the relationship to ovarian steroidogenesis remains unclear. Aim of the study was to compare urinary BPA (U-BPA) concentrations among PCOS women and control group. Second aim was to assess the relationship of U-BPA to ovarian steroidogenesis in the group with PCOS. Methods Eighty six Caucasian women (age 28.5 ± 5.1 years) diagnosed with PCOS and 32 controls of age 24.9 ± 4.4 years were included in the study. Fasting blood samples were analyzed for biochemical parameters and steroid hormones. U-BPA was measured in the morning urine sample using high pressure liquid chromatography. Results PCOS women had significantly higher U-BPA as compared with control group (p=0.0001). Those with high levels of U-BPA (U-BPA ≥2.14 ug/g creatinine) demonstrated higher serum insulin (p=0.029) and HOMA IR (p=0.037), lower serum estrone (p=0.05), estradiol (p=0.0126), FSH (p=0.0056), and FAI (p=0.0088), as compared with low-BPA group (U- BPA <2.14 ug/g creatinine). In PCOS women, U-BPA positively correlated with age (p=0.0026; R2=0.17), negatively with estradiol (p=0.0001, R2=0.5), testosterone (p=0.0078, R2=0.15), free-testosterone (p=0.0094, R2=0.12) and FAI (p=0.0003, R2=0.32), respectively. Conclusions PCOS women have significantly higher U-BPA concentrations than healthy controls. U-BPA positively correlates with age and negatively with ovarian steroid hormones suggesting a possible suppressive effect of bisphenol A on ovarian steroidogenesis.

The Relationship

Polycystic ovary syndrome (PCOS) is characterized by dysfunction of the ovaries, hyperandrogenism and combination of metabolic disorders that increase the risk of developing cardiovascular diseases.The objective: of the investigation was to study the serum level of adhesion molecules (ICAM-1, VCAM-1 and E-selectin) in women with PCOS with different body weights as a marker of endothelial dysfunction, and their relationship with other factors of cardiovascular pathology.Materials and methods. 45 women with PCOS were examined, among whom a group of obese people – 23 women (age: 22,82±3,03 years, BMI 35,67±4,6) and a non-obese – 22 women (age: 22,81±2,03 years, BMI 22,35±2,16). The control group included 20 women aged 20,15±2,15 years, BMI 21,32±2,19. The serum level of ICAM-1, VCAM-1 and E-selectin was determined by the enzyme immunoassay. The significance of the differences of mean values was determined by the Student’s t-test. Correlation and multivariate regression analysis was used to assess the relationship between the studied factors,.Results. We revealed a significant increase of the serum level of adhesion molecules in obese and non-obese women with PCOS in comparison with women in the control group: ICAM-1 – +54,18%, +36,72%, respectively (p<0,0001), VCAM-1 – +50,76%, +36,33% respectively (p<0,0001), E-selectin – +40,24%, +29,56% respectively (p<0,0001). The concentration of these factors was higher in obese women with PCOS compared to non-obese women with PCOS: ICAM-I – +12,76% (p=0,04), VCAM-1 – +10,58% (p=0,009), E-selectin – +8,24% (p=0,03); p<0,05. The relationship was established between insulin content, HOMA and Caro index, lipid metabolism, hyperandrogenemia and an increase of serum level of adhesion molecules (p<0,01).Conclusions. As a result of our study, an increase of serum level of adhesion molecules in PCOS was revealed, both in combination with obesity and normal body weight, which may be a manifestation of endothelial dysfunction in this pathological condition. An increase in the content of ICAM-1, VCAM-1, E-selectin may be associated with insulin resistance, dyslipidemia and hyperandrogenism.

The Relationship

The relationship between clinico-biochemical characteristics and self-reported psychological parameters in 42 women with polycystic ovary syndrome (PCOS) and 42 age-matched healthy controls was examined. The General Health Questionnaire was used (GHQ-12) to ascertain emotional distress and the Beck Depression Inventory (BDI) to determine depressive symptoms. Emotional distress, depressive symptoms, hirsutism score, body mass index (BMI), waist-to-hip ratio (WHR), luteinizing hormone/follicle-stimulating hormone ratio, serum total testosterone, dehydroepiandrosterone sulphate levels and the insulin resistance index were significantly greater in women with PCOS than in healthy women. The BDI and GHQ-12 scores of the women with PCOS were significantly higher than those of the control group (BDI, 11.69 ± 9.49 vs 5.80 ± 4.58; GHQ-12, 3.38 ± 3.38 vs 1.54 ± 1.97, respectively), and BMI and WHR were positively correlated with the BDI and GHQ-12 scores. Clinicians should be aware of the increased risk of emotional distress and depression in women with PCOS, especially those who are obese, and of the need to screen these patients for such symptoms.

Cardiometabolic Profile

Polycystic ovary syndrome (PCOS) is commonly associated with a higher cardiometabolic risk. The relationship between steroid hormones and cardiometabolic profile in PCOS has been evaluated, but no single hormonal predictor of this association has been identified to determine. To determine the relationship between steroid hormones and cardiometabolic risk factors in PCOS women. Study included 64 women diagnosed with PCOS. Fasting blood samples were analyzed for biochemical, metabolic parameters and sex steroid hormones. PCOS women with BMI≥27 had significantly higher serum free testosterone (FT), free androgen index (FAI), estrone (E1) (p=0.014, p=0.02, p=0.01) than those with normal weight. In all subjects E1 positively correlated with BMI (p=0.0067), serum insulin (p=0.0046), HOMA-IR (p=0.0125) and negatively with HDL-cholesterol (p=0.009). FAI positively correlated with serum cholesterol (p=0.0457), triacylglycerols (TAG) (p=0.0001), HOMA-IR (p=0.037), and glycemia (p=0.0001), negatively with HDL-cholesterol (p=0.029). In multiple linear regression model E1 most significantly predicted HOMA-IR, whereas FT/FAI predicted HDL-cholesterol and BMI. We conclude that PCOS women with marked overweight or obesity have higher FT, FAI and E1 as compared with nonobese PCOS subjects. E1 and FT may predict worse cardiometabolic profile in PCOS.

Diagnostic Features

Relevance: The clinical picture of polycystic ovary syndrome (PCOS) is extremely polymorphic, especially in adolescence. At the same time, the diagnostic criteria of PCOS in adolescence are still under discussion, and the hormonal parameters, including anti-Mullerian hormone range and hyperandrogenism, are not determined. The aim of the present study was to characterize the pivotal clinical and hormonal features of PCOS in adolescents and to establish the age-specific thresholds of the most essential hormonal parameters. Design: A case-control study. Methods: The study included 130 girls with PCOS according to the complete Rotterdam criteria, aged 15 to 17 years. The control group consisted of 30 healthy girls with a regular menstrual cycle of the same age. A complete clinical and laboratory examination, hormonal assays, and ultrasound of the pelvic organs were performed. The serums anti-Mullerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), LH/FSH, prolactin, estradiol, 17α-OH progesterone (17α-OHP), androstenedione, testosterone (T), dehydroepiandrosterone sulfate (DHEAS), sex hormone-binding globulin (SHBG), leptin, and free androgen index (FAI) were analyzed. The diagnostic accuracy of AMH, FAI, LH/FSH, T, and androstenedione levels in predicting PCOS in adolescents was established using a logistic regression model and calculating area under the receiver operator characteristic (ROC) curve (AUC). Results: The serum levels of LH (9.0 (5.4–13.8) vs. 3.7 (2.5–4.7) IU/L; p < 0.0001), LH/FSH (1.6 (1.0–2.3) vs. 0.7 (0.5–1.1); p < 0.0001), 17α–OHP (4.1 (3.2–5.1) vs. 3.4 (2.7–3.8) nmol/L; p = 0.0071), cortisol (464.0 ± 147.6 vs. 284.0 ± 129.7 nmol/L; p < 0.0001), prolactin (266.0 (175.0–405.0) vs. 189.0 (142.0–269.0) mIU/L; p = 0.0141), T (1.9 (1.2–2.5) vs. 0.8 (0.7–1.1) nmol/L; p < 0.0001), androstenedione (15.8 (11.6–23.2) vs. 8.3 (6.5–10.8) ng/mL; p < 0.0001), AMH (9.5 (7.5–14.9) vs. 5.8 (3.8–6.9) ng/mL; p < 0.0001), FAI (5.5 (2.8–7.0) vs. 1.6 (1.1–2.3); p < 0.0001), SHBG (37.0 (24.7–55.5) vs. 52.9 (39.0–67.6) nmol/L; p = 0.0136), DHEAS (6.8 ± 3.2 vs. 5.1 ± 1.5 μmol/L; p = 0.0039), and leptin (38.7 ± 27.1 vs. 23.7 ± 14.0 ng/mL; p = 0.0178) were significantly altered in the PCOS patients compared to the controls. Multivariate analysis of all studied hormonal and instrumental parameters of PCOS in adolescents revealed as the most essential: AMH level > 7.20 ng/mL, FAI > 2.75, androstenedione > 11.45 ng/mL, total T > 1.15 nmol/L, LH/FSH ratio > 1.23, and the volume of each ovary > 10.70 cm3 (for each criterion sensitivity ≥ 75.0–93.0%, specificity ≥ 83.0–93.0%). The diagnostic accuracy of PCOS determination was 90.2–91.6% with the combined use of either four detected indexes, which was significantly higher than the use of each index separately. The accuracy of PCOS diagnostics reached 92% using AMH and leptin concentrations when the value of the logistic regression function [85.73 − (1.73 × AMH) − (0.12 × Leptin)] was less than 70.72. Conclusions: The results of the study estimate the threshold for AMH, FAI, androstenedione, testosterone, LH/FSH, and ovarian volume, which could be suggested for use in the PCOS diagnostics in adolescents with a high sensitivity and specificity. Moreover, the combination of either four determined indexes improved the diagnostic accuracy for the PCOS detection in adolescents.

Polycystic ovary syndrome (PCOS) may result from hypersensitivity to insulin, which is negatively regulated by uncoupling protein (UCP)-2. Because cholesterol side-chain cleavage enzyme (CYP11A1) is closely linked to PCOS, the expression of UCP-2 and CYP11A1 in ovarian tissues from PCOS patients was examined in the present study. Twelve PCOS patients with hyperandrogenaemia who underwent laparoscopic ovarian wedge resection and 12 age-matched control patients who underwent contralateral ovarian biopsy were enrolled in the study. UCP-2 expression in early stage (primordial, primary and secondary) and late stage (sinus and mature) follicles was examined using immunohistochemistry, whereas UCP-2 and CYP11A1 mRNA and protein levels in ovarian tissue were determined using quantitative reverse transcription–polymerase chain reaction and western blot analyses, respectively. UCP-2 expression increased significantly with follicular development in both control and PCOS tissue, with expression in early stage follicles from PCOS patients significantly greater than that in controls. In addition, both UCP-2 and CYP11A1mRNA and protein levels, mean fasting blood glucose concentrations and fasting serum insulin levels were significantly higher in PCOS patients compared with the control group. Finally, a significant correlation between UCP-2 and CYP11A1 expression was found in PCOS but not control patients. In conclusion, in PCOS patients, there was a correlation between UCP-2 and CYP11A1 expression, which was significantly higher than in the control group. These changes in UCP-2 and CYP11A1 expression may mediate follicle development in PCOS.

Abstract Context Polycystic ovary syndrome (PCOS) is the most common endocrine disorder of reproductive-aged women, affecting approximately 5-20% of women of reproductive age. A previous estimate noted that the economic burden of PCOS approximates $3.7 billion annually in 2020 USD when considering only the costs of the initial diagnosis and of reproductive endocrine morbidities, not considering the costs of pregnancy-related and long-term morbidities. Objective To estimate the excess prevalence and economic burden of pregnancy-related and long-term health morbidities attributable to PCOS. Data Sources PubMed, EmBase and Cochrane Library. Study Selection Studies in which the diagnosis of PCOS was consistent with the Rotterdam, National Institutes of Health (NIH), or Androgen Excess & PCOS (AE-PCOS) Society criteria, or that used electronic medical record diagnosis codes, or diagnosis based on histopathologic sampling were eligible for inclusion. Studies that included an outcome of interest and a control group of non-PCOS patients who were matched or controlled for body mass index (BMI) were included. Data Extraction Two investigators working independently extracted data on study characteristics and outcomes. Data Synthesis Data was pooled using random-effects meta-analysis. The I 2statistic was used to assess inter-study heterogeneity. The quality of selected studies was assessed using the Newcastle-Ottawa Scale. Results The additional total healthcare-related economic burden due to pregnancy-related and long-term morbidities associated with PCOS in the United States is estimated to be $4.3 billion annually in 2020 USD. Conclusions Together with our prior analysis, the economic burden of PCOS is estimated at $8 billion annually in 2020 USD.
