description: In einer prospektiven Studie wurden bei 28 kritisch kranken Patienten einer interdisziplinären Intensivstation die Plasmaspiegel von TNF[alpha], sCD14, Interleukin-6 (IL-6), sICAM-1 und sE-Selektin gemessen. Ziel der Studie war es, die genannten Parameter in ihrer Wertigkeit als Frühparameter der Sepsis zu untersuchen. Die Plasmaspiegel der Parameter TNF[alpha], IL-6, sCD14, sICAM-1 und sE-Selektin wurden mittels ELISA-Testkits bestimmt. Insgesamt wurde in einem Zeitraum von 11 Beobachtungstagen täglich 10 ml Blut entnommen, zentrifugiert und bis zur Verarbeitung tiefgefroren. Gruppe 1:Patienten mit einer mikrobiellen Infektion, die im Beobachtungszeitraum keine Sepsis entwickelten. Alle Patienten dieser Gruppe überlebten,Gruppe 2:Patienten mit einer mikrobiellen Infektion, die im Beobachtungszeitraum eine Sepsis mit Organdysfunktion entwickelt haben und überlebten,
description: In a prospective study, we determined the plasma levels of TNF[alpha], sCD14, Interleukin-6 (IL 6), sICAM-1 and sE-Selectin of 28 critically ill patients on our interdisciplinary intensive care unit. The aim of our study was to find out if these parameters are valuable for the early diagnosis of septicaemia. Plasma levels of TNF[alpha], IL-6, sCD14, sICAM-1 and sE-Selectin were measured with ELISA-test-kits. In a period of 11 days, we took 10 ml of blood daily which was refrigerated until examination. GROUP 1:patients with bacterial infections who did not develop septicaemia. All of these patients survived.GROUP 2:patients with bacterial infections who presented with symptoms of disturbed organic function within the examination period and survived.GROUP 3: patients with bacterial infections who developped symptoms of severe septicaemia and died because of multiple organic failure. Results: In patients with septicaemia, TNF[alpha]-levels were significantly higher than in patients without septicaemia. TNF[alpha]-levels can not be used as prognostic parameters in septicaemia because of the short half-life-time.sCD14-levels were significantly higher in patients with septicaemia in the first two days of observation. sCD14-levels can not be used as a prognostic criteria in septicaemia.In patients with septicaemia, we found significant higher Interleucin-6-levels compareed to patients without septicaemia. IL6 prooved to be a good marker for septicaemia. In combination with plasma levels of Se_Selectin, it is criteria for severity of the septicaemia and propable outcome of patients.Pathologically high plasma levels of sICAM-1 were measured in patients with septicaemia. S-ICAM-1 is an early indicator for activation of withe blood cells and danger of septicaemia. The exact blood level of s-ICAM-1 did not correlate with the outcome of patients.sE-Selectin-levels were significantly higher in patients with septicaemia than in patients without septicaemia. The persistence of high sE-Selectin levels indicates possible septicaemia early and is correlated with the outcome of patients.
