The aim of the study – to assess the effect of lipid metabolism disorders on the risk of abnormal uterine bleeding in women of reproductive age.
Materials and Methods. Thirty women of reproductive age with abnormal uterine bleeding were examined. The expression of α-receptors for estrogen ER1, receptors for progesterone PgR and nuclear protein Ki-67 in the glands and stroma of the endometrium was performed by immunohistochemical method. Lipidogram parameters were evaluated, body mass index was determined, and anthropometry was performed.
Results and Discussion. When assessing nutritional status, the prevalence among patients of BMI> 25 kg/m2 was found to be 96.7 %, while signs of nutritional constitutional obesity were 33.3 %. The average BMI was (29.1±1.6) kg/m2. The expression of estrogen receptors ER1 was higher in the glands (Me (25 %; 75 %) = 100 (80; 100) than in the stroma (Me (25 %; 75 %) = 80 (60; 90). On the other hand, the number of cells with a positive reaction to PgR progesterone receptors in the stroma and glands did not practically differ in Me (25 %; 75 %) = 80 (50, 90). The expression of Ki-67 protein was higher in glands – (ME (25 %; 75 %) = 90 (70; 100), in the stroma it did not exceed 50 % ((Me (25 %; 75 %) = 40 (30; 50).
Conclusions. 1. In patients with abnormal uterine bleeding, lipid disturbances in the form of type 2b dyslipidemia are often found. 2. The severity of dyslipidemia correlates with the intensity of abnormal uterine bleedings and the expression of proliferation markers.
