Abstract

A method of detecting platelet thrombosis or organ failure in a patient suffering from disseminated intravascular coagulation (DIC) or systemic inflammatory response syndrome (SIRS), comprising analyzing a von Willebrand factor-cleaving protease and/or a cleaving factor thereof, is disclosed. A kit for detecting platelet thrombosis or organ failure in a patient suffering from DIC or SIRS, comprising an antibody or a fragment thereof which specifically binds to a von Willebrand factor-cleaving protease, and/or an antibody or a fragment thereof which specifically binds to a cleaving factor of the von Willebrand factor-cleaving protease, is disclosed.

Claims (30)

1. A method of predicting the amount of a von Willebrand factor-cleaving protease in a patient suffering from disseminated intravascular coagulation or systemic inflammatory response syndrome, said method comprising:

collecting a sample of blood or plasma from the patient; and

analyzing the blood or plasma sample for a significant increase in the amount of elastase, wherein the significant increase in the amount of said elastase is indicative of a significant decrease in the amount of said von Willebrand factor-cleaving protease.

2. The method according to claim 1 , further comprising:

analyzing the sample for the amount of said von Willebrand factor-cleaving protease; and

confirming that the prediction is correct by determining a decreased amount of the von Willebrand factor-cleaving protease.

3. The method according to claim 1 , further comprising:

analyzing the sample for said von Willebrand factor-cleaving protease; and

diagnosing the patient with platelet thrombosis, wherein the significant increase in said elastase and the significant decrease in said von Willebrand factor-cleaving protease are indicative of platelet thrombosis.

4. The method according to claim 1 , further comprising:

analyzing the sample for said von Willebrand factor-cleaving protease; and

diagnosing the patient with organ failure, wherein the significant increase in said elastase and the significant decrease in said von Willebrand factor-cleaving protease are indicative of organ failure.

5. The method according to claim 1 , further comprising:

analyzing the sample for said von Willebrand factor-cleaving protease; and

determining an appropriate treatment option, wherein the significant increase in said elastase and the significant decrease in said von Willebrand factor-cleaving protease are indicative of using an inhibitor of elastase.

6. A method of predicting the amount of elastase in a patient suffering from disseminated intravascular coagulation or systemic inflammatory response syndrome, said method comprising:

collecting a sample of blood or plasma from the patient; and

analyzing the sample for a significant decrease in the amount of von Willebrand factor-cleaving protease, wherein the significant decrease in the amount of said von Willebrand factor-cleaving protease is indicative of a significant increase in the amount of said elastase.

7. The method according to claim 6 , further comprising:

analyzing the sample for the amount of said elastase; and

confirming that the prediction is correct by determining an increased amount of the elastase.

8. The method according to claim 6 , further comprising:

analyzing the sample for said elastase; and

diagnosing the patient with platelet thrombosis, wherein the significant increase in said elastase and the significant decrease in said von Willebrand factor-cleaving protease are indicative of platelet thrombosis.

9. The method according to claim 6 , further comprising:

analyzing the sample for said elastase; and

diagnosing the patient with organ failure, wherein the significant increase in said elastase and the significant decrease in said von Willebrand factor-cleaving protease are indicative of organ failure.

10. The method according to claim 6 , further comprising:

analyzing the sample for said von Willebrand factor-cleaving protease; and

determining an appropriate treatment option, wherein the significant increase in said elastase and the significant decrease in said von Willebrand factor-cleaving protease are indicative of using an inhibitor of elastase.
