The role of cholecalciferol in the pathogenesis of polycystic ovary syndrome

Abstract

Objective to evaluate and compare clinical, anamnestic and laboratory data of patients with polycystic ovary syndrome (PCOS) and without syndrome, including the level of vitamin 25(OH) D3.
 Material and methods. In this work, 81 patients were examined, who, at the 1st stage of the study, were divided into two groups depending on the presence or absence of signs of PCOS. The main group included 51 patients with signs of PCOS. The control group included 30 healthy women without signs of PCOS, matched by sex and age with the main group. The main and control groups were compared by clinical and anamnestic data, including birth weight, by the presence of complications of pregnancy and childbirth in their mothers during their gestation, by the level of vitamin D. PCOS was verified on the basis of diagnostic criteria Rotterdam (2003) and International guidelines on PCOS (2018). Vitamin 25(OH)D3 was determined by mass spectrometry (ng/ml).
 At the 2nd stage of the study, the main group with PCOS was divided into 2 subgroups depending on the waist circumference (WT). Subsequently, the subgroups were compared with each other in the same parameters as at stage 1, as well as in the level of insulin, low-density lipoprotein (LDL), triglycerides (TG), anti-Mllerian hormone (AMH), follicle-stimulating hormone (FSH) and luteinizing hormone (LH). To reflect the statistical results, the parametric parameters of the Students t-test were applied for two independent samples with equal or different variance. For nominal data Pearsons Chi-test, when the means are not calculated and a test is carried out for the presence of a relationship between nominal variables.
 Results. There was no statistically significant difference in vitamin 25(OH)D3 levels in patients with and without PCOS. Statistically significant differences in vitamin 25(OH)D3 levels were found in women with PCOS, depending on the waist circumference (WT). In these subgroups, differences were also found in the level of insulin, LDL, TG.
 Conclusion. The values of the level of vitamin 25(OH)D3 do not differ in the groups of patients with PCOS and without PCOS, but significantly correlate with the metabolic profile of patients.
