Abstract Objectives: To assess variability and predictability of adiponectin, leptin, resistin and their ratios in non-obese and obese women with anovulatory polycystic ovary syndrome (aPCOS). Results: A total of 52 ovulatory controls (mean age=31.63±4.88 years, BMI=25.33±2.68 kg/m3); 54 non-obese [mean age=32.11±4.25 years, BMI=25.72±2.95 kg/m3] and 50 obese women with aPCOS [mean age= 33.64±4.14 years, BMI=39.19±2.99 kg/m3] were recruited. The aPCOS group had lower adiponectin [13.0(10.49-16.59) vs 18.42(15.72-19.92) µg/ml, p<0.0001], adiponectin: leptin ratio (A:L) [0.60(0.35-0.88) vs 1.19(0.92-1.37), p<0.0001], and adiponectin: resistin ratio (A:R) [0.30(0.21-0.43) vs 0.42(0.32-0.62), p<0.0001] but a higher leptin [20.02(14.54-26.80) vs 16.17(14.51-18.36) ng/ml, p<0.0001] and leptin: resistin ratio (L:R) [0.53(0.37-0.82) vs 0.40(0.27-0.48), p<0.0001] compared to the controls. The obese aPCOS group had lower adiponectin [11.04(5.66-13.25) vs 14.18(11.04-18.02), p<0.0001 and 18.42(15.72-19.92) µg/ml, p<0.0001], A:L [0.36(0.27-0.44) vs 0.78(0.61-1.16), p<0.0001 and 1.19(0.92-1.37), p<0.0001], and A:R [0.24(0.17-0.38) vs 0.40(0.23-0.58), p<0.0001 and 0.42(0.32-0.62), p<0.0001] but a higher leptin [26.80(14.28-32.09) vs 17.95(14.86-21.26), p<0.05 and 16.17(14.51-18.36) ng/ml, p<0.0001] and L:R [0.63(0.46-1.03) vs 0.41(0.30-0.61), p<0.0001 and 0.40(0.27-0.48), p<0.0001] compared to the non-obese aPCOS and control group, respectively. A:L showed the best discriminatory power in predicting aPCOS (AUC=0.83), followed by adiponectin alone (AUC=0.79), L:R and leptin alone (both AUC=0.69). Resistin alone had the poorest discriminatory power (AUC=0.48).

BACKGROUND: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders of women in the childbearing period. However, its pathophysiology is still unclear. Certain polymorphisms of the luteinizing hormone/choriogonadotropin receptor (LHCGR) genes may lead to changes in the bioactivity of this hormone. The important functional role of LHCGR in the metabolism of androgen and ovulation, the LHCGR gene variant, may be related to the risk of PCOS. AIM: The aim of this study was to evaluate the association between LHCGR Ins18LQ gene polymorphism and PCOS. METHODS: A case–control study was performed in women with PCOS and non-PCOS from May 2019 to October 2019 in HFC IVF Center. We included 50 women with PCOS and 50 healthy controls. Polymorphism of the LHCGR (ins18LQ) gene was genotyped using polymerase chain reaction-restriction fragment length polymorphism. RESULTS: From this study, we found that there was no significant difference in the proportion of ages between the groups (p > 0.05). There were significant differences in the characteristics of body mass index, FSH level, LH level, and LH/FSH ratio between the PCOS and control groups (p < 0.05). We also found that the proportion of heterozygote variant non-ins/ins was higher in the PCOS group compared to the control group, but there was no significant difference between the polymorphisms of the non-ins and non-nonins variants between the PCOS and control groups (p = 0.269). The frequency of ins alleles was higher in the PCOS group compared to the control group. CONCLUSION: There was no significant association between LHCGR ins18LQ gene polymorphism and PCOS.

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.

Abstract Background:Previous studies have shown that patients with polycystic ovary syndrome present with low-grade chronic inflammation. Our previous studies have confirmed that IL-18 is highly expressed in the serum and endometrium of patients with polycystic ovary syndrome. However, the mechanism of IL-18 elevation remains unclear. Therefore, this study aims to explore the signaling pathways that lead to the up-regulation of IL-18 in endometrium of PCOS patients. We predicted that C/EBP-β might be a transcription factor of IL-18 by using TF-Search tool, and deacetylase SIRT1 might be involved in its regulation. Method:SIRT1 and C/EBP-β in proliferative endometrium of PCOS patients and control group by immunohistochemical method.The expression was localized. The genes and proteins of SIRT1 and C/EBP-β in endometrium of PCOS and control group were detected by real-time quantitative PCR and Western Blot respectively. The interaction between C/EBP-β and IL-18 was verified by double luciferase assay. Result(s): The gene and protein levels of SIRT1 and C/EBP-β in proliferative endometrium of PCOS patients were significantly higher than those of the control group. Immunohistochemical experiments confirmed that SIRT1 was mainly expressed in endometrial nucleus, while C/EBP-β was mainly expressed in endometrial nucleus and cytoplasm. The interaction between C/EBP-β and IL-18 was confirmed by double luciferase assay. Conclusion: SIRT1 and C/EBP-β are highly expressed in endometrium of PCOS patients, and may play a role in the regulation of IL-18.

Objective: The study was conducted to determine whether there were differences in COX-2 expression in endometrial women with PCOS compared to fertile women. Methods: This study is a case-control study investigating the relationship between exposure (research factors) and disease, by comparing case group and control group based on their exposure status. The samples of this study were infertile polycystic ovary syndrome patients who were treated at the Sekar Fertility Clinic in Dr. Moewardi Hospital Surakarta, and fertile women seeking treatment at Dr. Moewardi Hospital Surakarta. The number of samples were 60 subjects consisting of 30 PCOS patients and 30 fertile women. The expression of COX-2 in endometrial biopsy LH + 5 until LH + 10 which meet the inclusion with Rotterdam criteria and exclusion criteria was checked by immunohistochemistry. The data was analyzed using the Mann-Whitney test. Results: The mean COX-2 expression in PCOS (10.83 ± 5.35) in fertile women (37.00 ± 7.76), p = 0.005. Regression test of COX-2 by adjusting external variables (occupation, age, education, menstrual disorders, familial history, menstrual cycle, menarche, obesity, contraception history) shows also higher expression in PCOS patient with OR = -7.063; CI = 0.462–108.066; p = 0.160. Conclusion: COX-2 expression in endometrium of women with PCOS is lower than it is in fertile women.

Objective: The aim of this study was to assess non-invasively endothelial function of young women with polycystic ovary syndrome (PCOS) in comparison with healthy age-matched women and a group of young women with idiopathic hirsutism (IH). The possible role of metabolic and hormonal parameters on endothelial function was also examined. Design: Descriptive clinical trial. Methods: Fifty-six women, 27 with PCOS, 16 with IH and 13 healthy age-matched women were studied. Endothelial function of resistance arteries was assessed by venous occlusion plethysmography. Metabolic and hormonal parameters were estimated in this study population. Results: The duration of reactive hyperemia (durRH) was shorter in PCOS group when compared with normal controls (63.75 ± 13.33 s vs 113.18 ± 20.92 s, P = 0.036). A similar finding was observed when PCOS were compared with IH group (63.75 ± 13.33 s vs 105 ± 17.20 s, P = 0.05). The durRH did not differ between IH and control group (105 ± 17.20 s vs 113.18 ± 20.92 s, ns). A significant positive linear correlation was found between the durRH and dehydroepiandrosterone-sulfate (DHEA-S) levels (r = +0.48, P = 0.04) in the PCOS group. The basal insulin resistance index (HOMA) differed significantly between PCOS, IH and control groups. There was no significant correlation between durRH and HOMA index or testosterone levels in the PCOS group. Conclusions: Endothelial dysfunction may be an early sign of cardiovascular system abnormalities in young PCOS women. It is possible that increased DHEA-S levels may offer a cardioprotective advantage that attenuates the effects of cardiovascular risk factors that accompany PCOS.

Introduction: Polycystic ovary syndrome (PCOS) is one of the most commonly recognized endocrinopathies in women. The literature lacks clear data that allow any meaningful conclusions to be drawn about the influence of trace elements in erythrocytes on the biochemical parameters of PCOS. Materials and methods: This study was conducted among 47 women meeting the Rotterdam criteria for the diagnosis of polycystic ovary syndrome. The research groups included women with PCOS with different BMI values (body mass index): obese women with PCOS (PCOS with BMI ≥ 30, mean BMI index 35.4 ± 4.4 kg/m2), nonobese PCOS women (PCOS with BMI < 30, mean BMI index 25.2 ± 2.8 kg/m2), and healthy control group (CG) with a mean BMI of 23.57 ± 0.9 kg/m2. The contents of trace elements in erythrocytes were determined with an inductively coupled plasma atomic emission spectrometer. Results: The only trace element showing significant differences in concentration between the studied groups was nickel (Ni). The level of nickel in the obese women with PCOS (BMI ≥ 30) was significantly higher than in nonobese women (BMI < 30). The content of other trace elements in erythrocytes did not differ significantly between the studied groups. Several significant correlations were found within each of the studied PCOS groups: in the group of obese women, the content of zinc (Zn) in erythrocytes positively correlated with prolactin, the content of magnesium (Mg) positively correlated with testosterone, and the content of manganese (Mn) negatively correlated with thyroid-stimulating hormone. In the group of nonobese women, Zn content correlated positively with testosterone, Ni with luteinizing hormone (LH) and estradiol, and Mg negatively correlated with estradiol. Conclusions: The relationship between the level of trace elements and the level of hormones suggests that, in obese women with PCOS, nickel may play a role in inhibiting the processes of folliculogenesis and ovulation. Research on trace elements and their relationship to ovulatory cycles and the development of PCOS may contribute to reducing the consequences of PCOS and, therefore, should be extended.

Objectives: Polycystic ovary syndrome (PCOS) is the most common cause of female infertility. The aim of this study was to compare the oocyte and embryo quality between the PCOS women with the control group candidate for in vitro fertilization/ intracytoplasmic sperm injection (IVF/ICSI). Materials and Methods: The present study was designed at the Infertility Research Center of Milad in the prospective cohort format and was carried out on 100 cases of infertile women with confirmed PCOS (case group) and the male factor (control group) as the first IVF cycle candidates. Both groups underwent the ovary stimulation cycle and ICSI under the standard antagonist protocol. The collected data were then processed and analyzed using the SPSS software, version 16. Results: The average age of study cases was 35±3, and oocyte necrosis was the underlying pathological factor in both groups (28% and 26% in the PCOS and control groups, respectively). In addition, most embryones belonged to either grade 1 or 2 or were 8-cell embryos. Furthermore, the highest number of transferred embryos among the patients was related to the 8-cell and grade 1. The occurrences of biochemical pregnancy in the PCOS and control groups were up to 31.91% and 22%, respectively, leading to 72.73% and 60% childbirth in cases of both groups. Finally, there were no significant differences observed with respect to the quality and the quantity of the embryones, the oocyte, the transferred embryo, the germinal vesicle oocytes, and the rate of pregnancy among the two groups (P>0.05). Conclusions: According to the results of the present study, no differences were found concerning the oocyte quality, embryo, and the pregnancy rate between PCOS cases and any other patients requiring ICSI. Therefore, such cases can similarly benefit from ICSI methods as well.
