Abstract

Objective: The development of organ dysfunction is the principal determinant of outcome in acute pancreatitis and is mediated through a systemic inflammatory response characterized by leukocyte and endothetial cell activation. Up-regulation of the endothelial cell adhesion molecules, E-selectin andP-selectin, is important for endothelial/leukocyte interactions. Levels ofserum-soluble E-selectin and P-selectin have been suggested as markers of endothelial activation. This study examines the kinetics of serum-soluble selectins in patients with acute pancreatitis complicated by organ dysfunction. Design:Prospective observational study. Setting: University teaching hospital with a specialist hepato-pancreatica-biliary service. Patients: Eighteen patients with acute pancreatitis were studied, nine of whom had organ dysfunction,Measurements and Main Results:Serial venous blood samples were collected an the first 3 days after admission for measurement of soluble E-selectin and P-selectin by enzyme-linked immunosorbent assay. In all patients, solubleP-setectin concentrations decreased significantly during the study period. Nonsurvivors had significantly higher levels of soluble P-selectin than survivors. In contrast, soluble E-selectin increased significantly during thestudy period in patients with organ dysfunction, whereas it remained constant in patients without evidence of organ dysfunction. Conclusions: These results suggest a role for endothelial-derived selectins in the development of organ dysfunction in patients with acute pancreatitis. The observed temporal differences in serum selectin concentrations is in keeping with in vitro observations of endothelial selectin expression.
