| Background/aim Polycystic ovary syndrome (PCOS) is a prevalent endocrine condition affecting 5–10% of reproductive-aged women, the cause of which is unknown. Chronic anovulation, polycystic ovaries, and hyperandrogenism are symptoms of PCOS. It is linked to hirsutism, obesity, and increased probability of cardiovascular disease, metabolic syndrome, and diabetes mellitus. A risk factor for cardiovascular disease is PCOS that is undiagnosed or untreated. Our aim in this study is to investigate serum fetuin-A level and its gene as potential biomarkers for screening of insulin resistance in PCOS. Patients and methods This study involved 100 female participants from outpatient clinic, Department of Obstetrics and Gynecology, Zagazig University Hospital, Egypt. They were split into two groups (each 50). The first group included healthy fertile women without symptoms of hyperandrogenemia as a control. The second group included women with PCOS. Fasting blood sugar levels, cholesterol, high-density lipoprotein cholesterol and triglycerides have been estimated by enzymatic colorimetric technique while low-density lipoprotein cholesterol was calculated. Enzyme-linked immunosorbent assays have been used to measure serum concentrations of luteinizing hormone, follicular-stimulating hormone, testosterone, and fetuin-A, while PCR has been used to extract DNA and genotype common functional polymorphisms in fetuin-A. Results The present results revealed a considerable rise in glucose, insulin, Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), cholesterol, triglyceride, low-density lipoprotein cholesterol, luteinizing hormone, testosterone, and fetuin-A and significant decrease in follicular-stimulating hormone and high-density lipoprotein cholesterol in PCOS patients. Also, there was significant higher frequency of the fetuin-A gene variant rs1071592 AA genotype and A allele compared to controls. Conclusions Fetuin-A has a potential diagnostic value as a biomarker for insulin resistance in PCOS associated with metabolic syndrome. Additionally, ‘CG’ allele can be considered a risk factor for PCOS. | ||
