OBJECTIVES: To determine concentrations of circulating adhesion molecules endothelial (E)-selectin, intercellular adhesion molecule (ICAM)-1, and vascular cell adhesion molecule (VCAM)-1 in children with sepsis-induced multiple organ failure (MOF), and to determine associations among increased concentrations of these circulating adhesion molecules and important outcome measures. DESIGN: Prospective study. SETTING: University pediatric intensive care unit. PATIENTS: A total of 77 consecutive children with sepsis and 14 acutely ill children without sepsis. INTERVENTIONS: Plasma E-selectin, ICAM-1, and VCAM-1 concentrations and organ failure index (indicating number of failed organ systems) were determined in 77 children on days 1 and 3 of sepsis, and in 14 control children on pediatric intensive care unit day 1. Multivariate logistic regression analysis was used to determine associations between adhesion molecule concentrations and clinically relevant outcome measures. MEASUREMENTS AND RESULTS: Plasma concentrations of E-selectin, ICAM-1, and VCAM-1 were increased in children with sepsis vs. control on day 1 (p < .05). Plasma VCAM-1 (but not ICAM-1 or E-selectin) was increased in children with more than three organ failures vs. children with less than three organ failures (p < .05). Plasma ICAM-1 and VCAM-1 (but not E-selectin) concentrations independently predicted number of organs failed and development of more than three organ failures. Plasma ICAM-1 and VCAM-1 also predicted mortality and development of sequential (pulmonary/hepatic/renal) MOF (p < .05). CONCLUSIONS: The pronounced and persistent increase in plasma VCAM-1 and ICAM-1 that occurs in children with sepsis and persistent MOF may indicate a phenotypic change in endothelium toward a more proinflammatory state. Alternatively, the source for these adhesion molecules may be activated leukocytes and other cell types. Future studies are required to determine the role of ICAM-1 and VCAM-1 in the pathogenesis of sepsis-induced MOF.
