Difference of Cyclooxygenase-2 (COX2) Expression in Endometrium Between Patients with Polycystic Ovary Syndrome (PCOS) and Fertile Women

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.

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.

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).

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 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.

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.

Objective: We evaluated levels of procalcitonin and proinflammatory markers in patients with polycystic ovary syndrome (PCOS) and compared them with controls in the Black Sea region of Turkey. Study Design: This prospective controlled study involved patients with PCOS (n=59) and healthy age-matched controls (n=26; total, n=85). Serum procalcitonin (PCT), white blood cells (WBCs), high-sensitivity C-reactive protein (h-CRP), homocysteine (Hcy) levels, insulin resistance, and lipid profiles were compared between the PCOS and control groups. The same parameters were also compared between overweight and normal-weight PCOS patients. Results: Serum PCT, Hcy, h-CRP, and WBC levels were similar in the PCOS and control groups. High-density lipoprotein (HDL) levels were lower in the PCOS group than in the control group (p <0.05). In a subgroup analysis of the PCOS group, there were no significant differences between overweight and normal-weight PCOS patients with regard to proinflammatory markers (serum WBC, h-CRP, Hcy, PCT levels). However, total cholesterol, LDL, and triglyceride levels were significantly higher in overweight PCOS patients (p <0.005). Serum HDL levels were significantly lower in the overweight PCOS group than in the normal-weight group (p <0.005). Fasting insulin and HOMA-IR levels were significantly higher in overweight PCOS than normal-weight PCOS patients (p<0.05). Conclusions: Serum PCT, h-CRP, WBC, and Hcy levels were within normal ranges in PCOS patients. These results may be related to the relatively young age and regional differences in the study group.

Objectives: To study the two gene polymorphism (DENND1A and THADA genes) among Iraqi women with polycystic ovary syndrome (PCOS). Materials and Methods: This case-control study was done at the Gynaecological Department of Al-Yarmouk Teaching Hospital of AI-Mustansiriyah College of Medicine, Baghdad during January-December 2018. Two-hundred women were enrolled in the study, including 100 women with PCOS as the case group and 100 healthy and age-matched women as the control group. Main outcome measures were to analyze DENND1a gene polymorphism rs2479106 and THADA gene polymorphism rs12478601 at genotype and allelic levels. Results: The DENND1A gene polymorphism rs2479106 had three genotypes of AA, AG, and GG. The homozygous mutant genotype (GG) was considerably related to the incidence of PCOS (OR=5.43, 95% CI=1.13-25.97, P=0.034) with 5-time more risk compared with those carrying the wild homozygous genotype (AA). The heterozygous genotype (AG) was more but not statistically different (OR=1.73, 95% CI=0.85-3.54, P=0.131). At the allelic level, G allele was two times more frequent among cases compared to control cases with a highly significant difference. THADA gene polymorphism rs12478601 had three genotypes of CC, CT, and TT. Although TT genotype was repeated more among the case group than controls, the difference was not significant (P=0.346). Likewise, no significant differences were found in the allele distribution of this polymorphism. Conclusions: In general, the DENND1A-rs 2479106 polymorphism was considerably related to the incidence of PCOS among Iraqi women while THADA-rs12478601 polymorphism was not.

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.
