Abstract

The main initiator of the development of PAH is the development of endothelial dysfunction of the pulmonary vessels. The cause of this dysfunction is associated with functional disorders of the serotonin system. This research is devoted to study the role of the serotonin system in the development mechanism of PAH in children with CHD. We examined 30 young children (from 1 month to 2 years) with congenital heart defects (CHD), which were divided into 3 groups: group I - 12 children with CHD complicated by pulmonary arterial hypertension (PAH); Group II - 9 children with CHD, not complicated by PAH; Group III - 9 relatively healthy children (control). The serotonin content of platelets, serum and serotonin transporter (SERT) in platelets was determined. To determine serotonin and its carrier, a quantitative enzyme-linked immunosorbent assay (Elisa kit) was used. The study was performed using the Serotonin ELISA diagnostic kit, IBL Hamburg at the automatic ELISA of the Evolis robotic station (BioRad). The results of our studies showed a pronounced (p <0.001) increase in SERT concentration in platelets in the group of children with CHD complicated by PAH compared with the group of children with CHD and the control group. The amount...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
