PurposeThis prospective clinical study was designed to compare interleukin 1 receptor antagonist (IL-1ra) and E-selectin concentrations in patients with severe acute pancreatitis to those with severe sepsis.Materials And MethodsNine consecutive patients with severe acute pancreatitis and 11 consecutive patients with severe sepsis admitted to a medical/surgical intensive care unit were included in the study. Plasma concentrations of IL-1ra and E-selectin were serially measured daily for 7 days or throughout their stay in the intensive care unit if shorter.ResultsThe concentrations of IL-1ra were significantly higher on admission in patients with severe sepsis compared with the patients with severe pancreatitis (median levels 10,500 and 2,600 pg/mL, respectively, P = .007). When the data from the first 3 days were analyzed using analysis of variance (ANOVA), the levels of IL-1ra and E-selectin were similar in both groups. The concentrations of IL-1ra and E-selectin correlated to the development of multiorgan dysfunction as assessed by sequential organ failure assessment (SOFA) score (P = .032 and .043, respectively).ConclusionThis study shows that IL-1ra and E-selectin are released in acute severe pancreatitis, and the levels seem to be comparable to those in patients with severe sepsis. Concentrations of IL-1ra and E-selectin correlate to the development of multiorgan failure as indicated by high SOFA scores during the first week of disease.
