Method for the diagnosis of sepsis with determination of soluble cytokeratin fragments
Method for early differential diagnosis and detection, for prognosis and assessment of the severity and for therapy-accompanying assessment of the course of sepsis and sepsis-like systemic infections, in which, preferably with additional determination of at least one further parameter suitable for sepsis diagnosis, the amount of soluble cytokeratin fragments, in particular of CYFRA 21-1, TPS, TPA and/or sCY1F, in a biological fluid of a patient in whom a sepsis is present or a sepsis is suspected is determined and conclusions with regard to the presence, the expected course, the severity and/or the success of initiated measures for the therapy of the sepsis are drawn from the determined amount of soluble cytokeratin fragments.
1. A method for diagnosis and detection of sepsis, comprising providing a biological fluid of a patient in whom sepsis is suspected based on clinical findings and elevated levels of procalcitonin in said patient; and determining the amount of cytokeratin fragment 21-1 (CYFRA 21-1) in said fluid wherein an elevated concentration of CYFRA 21-1 in said fluid as compared to healthy individuals is indicative of sepsis.
2. The method of claim 1 , wherein the amount of CYFRA 21-1 is determined by an immunodiagnostic assay method.
3. The method of claim 1 , wherein said biological fluid is patient's serum.
4. The method of claim 1 , wherein CYFRA 21-1 in an amount greater than 1 ng/ml is indicative of sepsis.
