Aim: To investigate the role of serum OKL38 levels in the development of polycystic ovary syndrome (PCOS) and clinical implications related to PCOS. Method: PCOS (n = 33) and ovulatory controls (n = 48) were recruited for the study. Anthropometric measurements were recorded, and blood samples for hormonal and biochemical parameters including serum OKL38 levels were obtained. The potential role of OKL38 on the development of PCOS, metabolic syndrome and cardiovascular disease (CVD) were investigated. Framingham risk score (FRS) was used for the determination of CVD risk. Results: Mean Ferriman–Gallway (FG) score, insulin, low-density lipoprotein (LDL), total cholesterol (TC) levels, and the homeostasis model assessment of insulin resistance index (HOMA-IR) were significantly increased (p <.05) in women with PCOS compared to controls. PCOS group had lower mean OKL38 level compared to controls (p <.0001) and OKL38 was negatively predictive for the diagnosis of PCOS after adjustment of variables that were significantly different between two groups. A negative association between OKL38 and metabolic syndrome in PCOS women was evident after adjustment for age, obesity, and abdominal obesity. OKL38 level was also negatively correlated with body mass index, waist-to-hip-ratio, fat composition, serum TC, LDL, free testosterone levels, FRS, and FG scores. Conclusion: OKL38 may have a partial role in the etiopathogenesis of PCOS and may protect development of metabolic syndrome and CVD in women with PCOS.
