Method for determining sepsis using pro-ADM
Uses of recombinant procalcitonin 3-116 in the diagnosis and therapy of septic diseases and the measurement of prohormones other than procalcitonin, and of dipeptidyl peptidase IV, as biomarkers in the diagnosis of sepsis.
1. A method for the detection of sepsis in an individual suspected of having sepsis, comprising;
contacting a blood, plasma or serum sample from the individual with an antibody which binds to human pro-adrenomedullin (pro-ADM) and/or a partial peptide thereof, and
determining the level of human pro-ADM and/or said partial peptide, wherein an increase in said level compared to healthy individuals is indicative of sepsis
wherein said partial peptide differs from the known complete peptide sequence of human pro-ADM by the absence of the first two amino acids at the amino terminus thereof or consists of amino acids 45-92 of pro-ADM.
2. The method of claim 1 for differential-diagnostic early detection of sepsis.
3. The method of claim 1 for assessment of the severity of sepsis or a sepsis-like systemic infection.
4. The method of claim 1 for assessment of the success of a therapeutic treatment of sepsis or a severe sepsis-like infection.
5. The method of claim 1 further comprising determination of at least one other indicator of sepsis.
6. The method of claim 5 wherein said at least one other indicator of sepsis is procalcitonin.
7. The method according to claim 1 , wherein a partial peptide of human pro-ADM is detected which differs from the known complete peptide sequence of human pro-ADM by the absence of the first two amino acids at the amino terminus thereof.
8. The method of claim 7 wherein said dipeptide is cleavable by dipeptidyl-aminopeptidase IV (DP IV; DAP IV or CD26).
9. The method according to claim 1 , wherein said determination of human pro-ADM and/or said partial peptide is carried out as an immunoassay or a precipitation assay, and a diagnosis of the presence of sepsis or severe sepsis-like infections is made if the concentration of pro-ADM and/or said partial peptide determined is significantly higher than the concentration observed in healthy persons.
10. A method for the detection of sepsis in an individual suspected of having sepsis, comprising;
contacting a blood, plasma or serum sample from the individual with an antibody which binds to human pro-adrenomedullin (pro-ADM) and/or a partial peptide thereof, and
determining the level of binding of said antibody, wherein an increase in said level compared to healthy individuals is indicative of sepsis
wherein said partial peptide differs from the known complete peptide sequence of human pro-ADM by the absence of the first two amino acids at the amino terminus thereof or consists of amino acids 45-92 of pro-ADM.
