RESUMO

OBJECTIVE: The objective of this study was to investigate the allele frequencies of polymorphisms in genes CYP11A1 rs4886595 and CYP11A1 rs4887139 that are responsible for the steroidogenesis mechanism in polycystic ovary syndrome patients and control females. METHODS: Samples were obtained from the Department of Obstetrics and Gynecology in the Near East University Hospital from September 2019 to December 2019. Only the nonobese patients between the ages of 18-40 years were included in this study following informed consent. Obese patients and patients more than 40 years of age were excluded from the study. Nonobese women and normal ovulation were included in the control group. DNA was isolated from blood samples. Real-time polymerase chain reaction (PCR) was used to analyze single nucleotide polymorphisms (SNPs) in various genes linked to polycystic ovary syndrome. The studies were carried out using the samples obtained from 120 women, of whom 55 were nonobese and had normal ovulation, and 65 were polycystic ovary syndrome patients. The allelic frequencies of SNPs in genes linked to polycystic ovary syndrome were calculated using real-time PCR outcomes. RESULTS: The variation of the CYP11A1 rs4887139 G>A did not show any significance, while the variation of CYP11A1 rs4886595 C>A showed significant differences between the patient and the control groups (p=0.01), respectively. CONCLUSION: Future research ought to focus on elucidating the susceptible causes of polycystic ovary syndrome with a wide range of SNPs and more sample size. The genome-wide association studies in polycystic ovary syndrome patients of different origin will be important to identify candidate genes as well as proteins that are implied in polycystic ovary syndrome risk.

RESUMO

OBJECTIVE: Polycystic ovary syndrome is a hormonal disorder that normally affects women of reproductive age in the range of 18-44 years. This study aimed to investigate the allelic frequencies of two polymorphisms, IRS rs18012781 and INSR rs1799817, which are suspected to be involved in polycystic ovary syndrome. METHODS: The samples were obtained from the patients admitted to the Near East University Hospital, Department of Gynecology and Obstetrics. The samples were divided into two groups: control and polycystic ovary syndrome groups. Blood samples were collected from 55 women in the control group and 65 samples from the patient group. DNA from whole blood was obtained. The allelic frequencies of single-nucleotide polymorphisms were determined using real-time PCR. Results were presented as the heterozygous and homozygous state of the single-nucleotide polymorphisms. RESULTS: There were no significant differences in the allelic frequencies of the single-nucleotide polymorphisms between the patient and control groups. Further statistical analysis investigating the INSR Tm using the Mann-Whitney U test value revealed that there was no difference in the homozygous and heterozygous state of INSR rs1799817. The result of this study showed that there was no statistically significant difference between the allelic frequencies of IRS1 rs1801278 and INSR rs1799817 between the patient and control groups. CONCLUSION: These single-nucleotide polymorphisms do not seem to modify the risk of polycystic ovary syndrome, and they cannot be used as a marker in clinical circumstances to evaluate the possible occurrence of polycystic ovary syndrome.

RESUMO

OBJECTIVE: Asporin is secreted by theca cells in the mouse ovaries and is an effective marker at the gonadotropin-independent stage in secondary follicle development. It has an inhibitory effect on transforming growth factor beta and bone morphogenic proteins, which are involved in androgenesis process. Our aim was to compare serum asporin levels of polycystic ovary syndrome and control groups and examine the relationship between asporin and hyperandrogenism. METHODS: A total of 60 patients, i.e., 30 polycystic ovary syndrome group and 30 controls, were included in the study. The demographic characteristics, hormonal status, and serum asporin levels of patients were evaluated and compared for each group. In addition, polycystic ovary syndrome patients were analyzed according to the presence of hyperandrogenism. Receiver operating characteristic curve analysis was performed for asporin levels in order to distinguish polycystic ovary syndrome patients from controls. RESULTS: Body mass index, serum asporin and androgen levels, free androgen index, and insulin resistance values were statistically significantly higher in polycystic ovary syndrome group. Serum asporin levels were statistically significantly higher in hyperandrogenic polycystic ovary syndrome patients compared to non-hyperandrogenic polycystic ovary syndrome women (p=0.010). Receiver operating characteristic curve analysis was done for serum asporin levels to distinguish between polycystic ovary syndrome patients and healthy controls (area under the curve=0.676, standard error: 0.070, 95%CI: 0.539-0.812, p=0.019, 63.3% sensitivity, and 70% specificity). CONCLUSION: The elevation of serum asporin levels in patients with polycystic ovary syndrome may be associated with the pathogenesis of this syndrome, or it may be the consequence of the disease. This relationship may be explained through the androgen mechanism.

RESUMO

OBJECTIVE: This study aimed to examine inflammation markers in patients with polycystic ovary syndrome (PCOS) and to compare them with healthy women. METHODS: This prospective study was conducted by examining patients who applied to the Near East University Gynecology and Obstetrics Outpatient Clinic between January 2019 and January 2020. A total of 110 PCOS patients with 135 control groups were compared in terms of metabolism, hormonal factors, and inflammation markers. RESULTS: The neutrophil count, neutrophil-lymphocyte ratio (NLR), platelet, platelet-lymphocyte ratio (PLR), platelecrit (PCT), erythrocyte cell distribution width, platelet distribution width, mean platelet volume, and C-reactive protein (CRP) values were found to be statistically significantly higher in patients with PCOS. There was a positive correlation between inflammation markers and serum androgens. Also, a positive correlation was observed between inflammation markers and cardiovascular risk parameters. In receiver operating characteristic curve analysis, the most valuable parameter in distinguishing PCOS patients from healthy controls was serum CRP levels [areas under the curve (AUC)=0.928, 95%CI 0.894-0.963, p<0.001, 92.6% sensitivity, and 82.7% specificity]. CONCLUSIONS: Serum CRP, neutrophil count, and PCT and NLR levels are valuable markers that show the inflammatory process in PCOS patients.
