THE STATE OF FETOPLACENTAL SYSTEM AT EXACERBATION OF CHRONIC NONOBSTRUCTIVE AND OBSTRUCTIVE BRONCHITIS IN WOMEN IN III TRIMESTER OF PREGNANCY

Abstract

The blood supply and ultrasound picture of fetoplacental complex, the concentration of secretory immunoglobulin A, circulatory immune complexes and the level of endotoxemia in 53 women at exacerbation of chronic nonobstructive and obstructive bronchitis in III trimester of gestation were studied. The first group included 28 patients with exacerbation of chronic nonobstructive bronchitis, the second one had 25 women with exacerbation of chronic obstructive bronchitis. 25 women with physiologic course of pregnancy became the control. It was found out than in III trimester of gestation in women of the 2nd group there was the rise of the vessel resistance in the right uterine artery till 3.06±0.08 relative units, in the umbilical artery till 3.86±0.08 relative units, and in the medial cerebral artery till 5.31±0.10 relative units in comparison with the first group where these indices were 2.75±0.10 relative units (р<0.05), 3.59±0.07 relative units (р<0.05) and 5.01±0.08 relative units (р<0.05), respectively. In the second group the thickening of placenta (36.0%) and loop of cord (45.6%) were registered oftener, which changes hemodynamics and optimal conditions of delivering the energetic substrate to the intrauterine patient. In the first group these parameters were 7.1% (p<0.05) and 7.1% (р<0.05), respectively. At the same time the concentration of secretory immunoglobulin A decreased till 3.2±0.23 g/L at the rise of the concentration of circulatory immune complexes till 0.23±0.005 units of optical density and mean molecular peptides till 0.288±0.005 units of optical density. In the first group the indices were 5.2±0.44 g/l (р<0.001), 0.20±0.003 units of optical density (р<0.001), 0.274±0.004 units of optical density (р<0.05), respectively. This proved the worsening of local immune protection of airway mucosa, autoimmune restructuring of the mother’s organism and endotoxemia, all of which increase the conductance of hematoplacental barrier for germs and their toxins as well as the risk of damage of endothelial lining of blood vessels of the system «mother-placenta-fetus».
