Serum neudesin levels in patients with polycystic ovary syndrome

Objectives: We aimed to investigate serum neudesin levels that has neural, metabolic functions in patients with poly-cystic ovary syndrome (PCOS).Material and methods: The study included 180 women (age range, 18-44 years) with a diagnosis of PCOS and a con-trol group that included 100 healthy females (age range, 18-46 years). Body mass index (BMI), waist circumference, Ferriman-Gallwey score, was evaluated and plasma glucose, lipid profile, estradiol, progesterone, total testosterone, prolactin, insulin, dehydroepiandrosterone sulfate (DHEA-S), FSH, LH, free T3, free T4, thyroid stymulating hormone (TSH), anti-thyroperoxidase (anti-TPO) antibody and neudesin levels were evaluated in all participants.Results: BMI and waist circumference were similar between two groups. Ferriman-Gallwey score was significantly higher in the patient group. Fasting blood glucose, HbA1C, lipid parameters except triglyceride levels, free T3, free T4, TSH, anti-TPO were similar between the two groups. Triglyceride, insulin and HOMA values were significantly higher in PCOS patients. While follicle-stimulating hormone (FSH), estradiol, progesterone, prolactin and DHEAS levels were similar, LH was significantly higher in patients with PCOS. Serum neudesin level was significantly lower in PCOS patients with respect to controls (p = 0.015). Neudesin was positively correlated with insulin (r = 0.224, p = 0.037), and progesterone (r = 0.716, p = 0.001). Multiple regression analysis revealed that neudesin correlated with only progesterone (beta = 0.308, p = 0.001).Conclusions: Due to the association of decreased levels of neudesin with PCOS and correlation of neudesin with pro-gesterone, neudesin may be related with one of patophysiologic pathways of PCOS. Still, it is not certain that decreased neudesin is involved in the pathogenesis of PCOS or is the result of the disorder.
