Influence of Arterial Hypertension on the Pregnancy in Women with RH-Negative Blood
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.
