FEATURES OF THE FUNCTIONAL STATE OF PLATELETS AT THE PRE-CLINICAL STAGE OF PREECLAMPSIA

Abstract

The only effective method of treating pregnant women with developed preeclampsia is timely delivery, so it is an urgent task to establish predictors of preeclampsia in order to predict its development.The aim of the work is to evaluate the platelet link of the hemostasis system in the 2nd trimester of pregnancy in patients with preeclampsia that developed after 34 weeks of pregnancy, to establish informative markers for predicting the development of preeclampsia after 34 weeks of pregnancy A survey of 210 apparently healthy women of active reproductive age (18-34 years) was carried out. Patients with multiple pregnancies, autoimmune pathology, arterial hypertension, heart defects, varicose veins, diabetes mellitus, hereditary thrombophilia were excluded from the study. All patients received voluntary informed consent to use the survey data for scientific purposes. In 20 patients, the course of pregnancy was complicated by the development of moderate preeclampsia after 34 weeks of pregnancy, these patients constituted the main group. 190 women with physiological pregnancy made up the comparison group. The study of the state of the platelet link of the hemostasis system was carried out using a VS-3000 + hematological analyzer, the number of platelets, their average volume, the root-mean-square value of the spread of platelet sizes, and the percentage of megalothrombocytes were determined. At the preclinical stage of development of preeclampsia (at 20-22 weeks), a decrease in the number of platelets and an increase in functional activity in the form of an increase in the rate of platelet anisocytosis, the average volume of platelets and the number of megalothrombocytes were found in pregnant women of the main group. Determination of indicators of the state of the platelet hemostasis at 20-22 weeks of gestation can be used to predict the development of moderate preeclampsia after 34 weeks of gestation.
