The purpose of the study was to assess the role of arterial hypertension (AH) in the development of immunization in women with Rh-negative blood to optimize perinatal outcomes.
Subject and methods. A prospective comparatively study was conducted in 3 groups of pregnant women with Rh-negative blood. The 1-st group (n=148) was with hypertensive disease (HD), the 2-nd group (n=144) - with gestational arterial hypertension (GAH); the 3-rd group (n=110) - without somatic pathology. The immune-hematological studies included a definition of the partial D antigen using gel method.
Results. It was definited that the pregnancy of these patients accompanied by the high frequency of early gestational toxicosis, threatened premature birth, preeclampsia, placental insufficiency as well as expressed changes immu-nological properties of blood, which are pathogenetic basis of fetal and neonatal rhesus hemolytic disease. Antibodies (AB) in the blood serum of patients with hypertension were detected in the first half of pregnancy (up to 20 weeks) in 1.2-1.4 times more often than in healthy women, high titer of AB rate in patients with HD was significantly higher compared to other groups. Disadvantageous combination of immunoglobulins subclasses Gl and G3 was found in the group of pregnant women with HD (11.4%) and GAH (10,8%), significantly less frequently (6,45%) in the control group.
Conclusion. To improve maternal, fetal and neonatal gestation outcomes the authors justified the necessity of prenatal work-up and delivery of these women.
The study was performed to find association between some cytokine status indicators, level of vascular endothelial growth factors and vitamin D in women with infertility and external genital endometriosis (EGE) in order to increase the effectiveness of its treatment. The low vitamin D status in the dynamics was determined in 240 patients aged 25 to 35 years with EGE planning pregnancy by determining the level of 25 (OH) D in the blood serum using the chemiluminescent method. Interleukin status (IL-1β, IL-6, IL-4), TNF-α, VEGFR-1 in blood serum was determined using enzyme-multiple immunoassay. The results of the studies revealed an increased level of IL-6, IL-1β and TNF-α in groups with low vitamin D content. In normal vitamin D significantly lower levels of vascular endothelial growth factor (VEGFR-1 ) in the blood serum were registered. Pregnancy rates were higher in groups with normal 25(OH)D levels in the blood serum. The mean serum VEGFR-1 level in pregnant women who became pregnant on their own was 1.3–1.5 times lower.
