Özet
Objective: We aimed to assess possible genomic instability in women with polycystic ovary syndrome (PCOS). Design: The frequency of micronuclei in cultured peripheral lymphocytes was used as a biomarker of genomic instability in somatic cells. Methods: Nineteen women, diagnosed with PCOS and 19 healthy female volunteers of corresponding ages and body-mass index (BMI) were included in the study. Micronuclei frequencies were assessed in cytokinesis-blocked lymphocytes. Results: The frequency of micronucleated cells (per thousand) was 9.00 (5.00) (interquartile range in parentheses) for patient group and 3.0 (3.0) for the control group (P < 0.0001, Mann-Whitney U-test). The serum levels of follicle-stimulating hormone (FSH), estradiol, prolactin, glucose and dehydroepiandrosterone sulfate (DHEAS) and the homeostasis model of assessment of insulin resistance (HOMA-IR) were not different between the two groups (P > 0.05). Serum total testosterone, luteinizing hormone (LH) and insulin levels and hirsutism score in the PCOS group were significantly (P = 0.007, P < 0.0001, P = 0.009 and P < 0.0001 respectively) higher than those of the control group (2.3 (2.1) nmol/l vs 1.7 (0.4) nmol/l; 8.5 (5.88) mU/ml vs 4.8 (4.4) mU/ml; 6.8 (5.1.) mu U/ml vs 9.7 (4.2) mu U/ml; 19.5 (6.5) vs 4.0 (2.5) respectively). However, the mean level of sex hormone-binding globulin (SHBG) in PCOS group was significantly (P = 0.004) lower than in control group (36.4(22.6) nmol/l vs 48.6(25.2) nmol/l respectively). Conclusion: These findings suggest that women with PCOS have a high incidence of genomic instability, and this condition is positively correlated with the hirsutism score, BMI. LH and serum total testosterone and insulin levels, and is negatively correlated with SHBG.
