AbstractThe pulmonary endothelium synthesizes many bioactive compounds and their activation or injury may cause release these substances into the blood. We determined the influence of trauma severity for endothelium activation/injury by measurement of specific endothelial cell markers--soluble E-selectin (sES) and von Willebrand factor antigen (vWF:Ag). Thirty six severely traumatized patients were stratified according to an Injury Severity Score (ISS). Group I--patients with ISS > or = 35, Group II--patients with ISS < 35. Eleven healthy volunteers served as controls. Serum sES and plasma vWF:Ag concentrations were measured and PaO2/FiO2 ratio, Lung Injury Score (LIS) and APACHE II ratio were calculated at the admission to IC, after 24 h and on 2, 3, 5, 7, 10th day. In all investigated time periods, we observed significant increase in serum sES concentration among patients from group I, in comparison to initial value and control. On day 3, serum sES concentration was significantly increased in group I, in comparison to group II. In the first seven days, plasma vWF:Ag concentration in patients with severe multiple trauma (ISS > or = 35) was significantly elevated, in comparison to group II and control. At the admission, significant correlation between plasma vWF:Ag and ISS was found (Rs = 0.568, p < 0.001). Significant correlation between plasma vWF:Ag and serum sES concentration was also observed (Rs = 0.501, p < 0.001). In conclusion, severe trauma patients manifest endothelial cell activation/injury. Plasma vWF:Ag concentration seems to be an important, early marker of trauma severity, while serum sE-selectin level may serve as prognostic factor in immediate postinjury period course.
