VASCULAR ENDOTHELIAL GROWTH FACTOR AS A MARKER OF ENDOTHELIAL DYSFUNCTION IN THE PREGNANT WOMEN WITH OBESITY

Today, obesity is one of the most common diseases worldwide and is a risk factor for obstetric and perinatal complications. Therefore, the purpose of the study is to determine the vascular endothelial growth factor in the blood serum of pregnant women with physiological body weight and obesity of varying degrees in the first and third trimesters of gestation. Materials and methods. The subjects were divided into 6 groups. The first group (control) consisted of pregnant women with physiological body weight in the first trimester; the second group included pregnant women with physiological body weight in the third trimester; the third group involved pregnant women with obesity Class I in the first trimester (20 women in each group); the fourth group - pregnant women with obesity of Class I in the third trimester (15 women); the fifth group - pregnant women with obesity of Classes II – III in 1st trimester (20 women); the sixth group – pregnant women with obesity of Classes II – III in the third trimester (15 women). Results and discussion. The article presents the evaluation of angiogenesis in pregnant women with physiological body weight and in pregnant women with concomitant obesity. The analysis of the results obtained has demonstrated the following pattern: the blood serum angiogenic factor decreases as obesity increases over I and III trimesters. Conclusions: 1. The endothelial growth factor of blood vessels in pregnant women with physiological body weight increases as pregnancy progresses. 2. Сoncentration of vascular endothelial growth factor in the serum of pregnant women with concomitant obesity in the 1st and 3rd trimesters of pregnancy naturally decreases with increasing severity of obesity, and its indicators in pregnant women with obesity in the 1st trimester can be used to predict the occurrence of obstetric complications associated with obesity.
