LEPTIN LEVEL IN WOMEN OF REPRODUCTIVE AGE WITH THE SYNDROME OF THE POLYCYSTIC OVARY IN COMPARISON WITH HEALTHY WOMEN

Material and methods. The study included 200 women of reproductive age, of whom the 1st group included 100 PCOS female patients and the 2nd group included 100 healthy women examined using clinical, instrumental, laboratory, and statistical methods. Results. Metabolic syndrome was diagnosed in 38 (38.0%) PCOS women of early reproductive age, while in healthy women only in 25 (25.0%) (p = 0.102). The serum leptin content in PCOS women amounted of 13.85 ng/ml (4.15-17.6), which was not significantly different from that of healthy women - of 8.9 ng/ml (5.5-18.4) (p = 0.732). However, in women with manifestations of metabolic syndrome (overweight and obesity), the level of leptin was higher than in women without metabolic syndrome - 16.7 ng/ml (15.6-18.8) and 19.3 ng/ml (17.4-22.8) in PCOS women - 31.7 ng/ml (21.6-38.6) and 27.3 ng/ml (20.1-32.1) in healthy women (p = 0.045 and 0.604, respectively). An increase in its level correlated with an increase in BMI (p = 0.001). We found that an increase in leptin levels in PCOS women of reproductive age correlated with its main manifestations: menstrual disorders, infertility and ultrasound parameters of the ovaries, with an increase in BMI, the relationship was stronger. Conclusion. Thus, in PCOS women of reproductive age, metabolic syndrome is more often diagnosed than in healthy women. Overweight and obesity are of major importance in the formation of metabolic disorders. Increased leptin levels exacerbate metabolic manifestations, leading to impaired ovulation and fertility. The results show the need to determine the level of leptin as an additional diagnostic criterion for metabolic syndrome in PCOS cases.
