SIRS that is mild soon remit naturally but some SIRS are severe and may change into multiple organ failure (MOF) associated with serious infections and tissue damage. If early differential diagnosis were possible, early measures could be taken to prevent poor outcomes. Endothelial selectin (E-selectin) is a single-chain glycoprotein that belongs to the selectin family. It is distributed in vascular endothelial cells, and is one of the cell adhesion molecules that contribute to the adhesion between endothelial cells and neutrophils and monocytes. E-selectin is induced by proinflammatory cytokines, and it appears in the blood of inflammatory disease and cancer patients. In this study, we investigated the correlations between soluble E (sE) -selectin with severity, outcome, and functional failure of individual organs, and we assessed the usefulness of sE-selectin for judging outcome in severe cases. The subjects were 50 emergency patients brought to our center, diagnosed with SIRS and had a Sequential Organ Failure Assessment (SOFA) score of 3 or more. The method consisted of measuring sE-selectin on arrival at the hospital (day 0) and on hospital days 1, 3, 5, and 7, and then testing for correlations with organ failure and survival. The results showed patients who died within 28th hospital day either had significantly higher sE-selectin levels on arrival or continued to have high levels within 7 days of admission than those who survived. This finding made it possible to predict the outcome of the patients. MOF group showed significantly higher levels than the non-MOF group. The number of failing organs increased as the sE-selectin values rose, and there was a positive correlation between the changes in SOFA scores and sE-selectin values. Testing for correlations between the sE-selectin values and each organ failure showed that the serum sE-selectin levels were most significantly correlated with the PaO_2/FiO_2 ratio (P/F ratio), which reflects the degree of failure to the respiratory system. In addition, comparison of the acute lung injury (ALI)/adult respiratory distress syndrome (ARDS) group and the non-ALI/non-ARDS group showed that the sE-selectin levels were significantly higher in the ALI group. A significant correlation was also found between the sE-selectin values and DIG score. Furthermore, the sE-selectin levels also significantly increased in the DIG than in non-DIC group. Based on the above findings, sE-selectin measurements correlated with DIG scores, SOFA scores, functional failure of the respiratory system, coagulation, and kidney. Since the sE-selectin level also correlated with patient survival, it may be a useful blood marker for predicting severity outcome and survival in critically-ill patients.}, pages = {467--476}, title = {Soluble Endothelium-selectin (sE-selectin) in Critically III Patients}, volume = {76}, year = {2006} }
