8 ABSTRACT The inflammatory process, associated with endothelium activation, is one of the possible mechanisms of the initiation of spontaneous delivery. The mode of delivery may affect the concentrations of inflammatory molecules and microvesicles produced by endothelial cells. These biomarkes might be used to detect neonatal pathologies. The aim of our study was to assess endothelial biomarkers in cord and neonatal blood following different modes of delivery: i.e. spontaneus vaginal delivery and elective cesarean section. The study group consisted of neonates and their mothers after uncomplicated pregnancy and spontaneous vaginal delivery (spontaneous group) and after elective caesarean section (elective group). The patient samples were taken from the cord blood and from the peripheral venous blood of the newborns between 48- 72 hours of life. Soluble biomarkers were measured using a multiplex immunoassay based on the Luminex® xMAP platform. The concentration of microvesicles and surface antigen-specific microvesicles was determined by flow cytometry. We found significantly increased concentrations of cord blood soluble endothelial markers and cell-membrane derived endothelium specific microvesicles after spontaneous vaginal delivery compared to elective cesarean section. Irrespective of the delivery mode...
