Kallikrein-inhibitor therapies
View Patent ↗Methods are described for preventing or reducing ischemia, e.g., cerebral ischemia, and/or reperfusion injury, e.g., reperfusion injury associated with cerebral ischemia, in a patient.
1. A method for preventing or reducing reperfusion injury in the central nervous system in a patient, the method comprising:
administering to the patient a composition comprising an inhibitor of plasma kallikrein, a said inhibitor of plasma kallikrein comprising a polypeptide, said polypeptide comprising amino acids 3–60 of SEQ ID NO: 2, in an amount effective to prevent or reduce neurocognitive defects due to reperfusion injury and/or damage to the central nervous system.
2. The method of claim 1 wherein the reperfusion injury is reperfusion injury associated with cerebral ischemia.
3. The method of claim 2 wherein the cerebral ischemia is a stroke.
4. The method of claim 3 , wherein the stroke is selected from the group consisting of an embolism associated stroke, a thrombus-associated stroke, a thromboembolitic stroke and a hemorrhage-associated stroke.
5. The method of claim 3 , wherein the stroke is an embolism-associated stroke.
6. The method of claim 3 , wherein the stroke is a thrombus-associated stroke.
7. The method of claim 6 , wherein the thrombus-associated stroke is a perioperative stroke.
8. A method for preventing or reducing reperfusion injury in a patient, the method comprising administering to the patient a composition comprising an inhibitor of plasma kallikrein, said inhibitor comprising a polypeptide, said polypeptide comprising amino acids 3–60 of SEQ ID NO: 2, wherein the reperfusion injury is prevented or reduced.
9. A method for preventing or reducing perioperative blood loss due to a surgical procedure performed on a patient, the method comprising administering to the patient a composition comprising an effective amount of a kallikrein inhibitor, wherein the kallikrein inhibitor comprises a polypeptide and the polypeptide comprises amino acids 3–60 of SEQ ID NO: 2, wherein the perioperative blood loss is prevented or reduced.
10. The method of claim 9 , wherein the surgical procedure is a cardiothoracic surgery.
11. The method of claim 10 , wherein the cardiothoracic surgery is cardiopulmonary bypass or coronary artery bypass grafting.
12. The method of claim 9 , wherein the the polypeptide comprises amino acids 1–60 of SEQ ID NO:2.
13. The method of claim 9 , wherein the polypeptide consists of amino acids 1–60 of SEQ ID NO:2.
14. The method of claim 11 , wherein the kallikrein inhibitor consists of a polypeptide and the polypeptide consists of amino acids 1–60 of SEQ ID NO:2.
15. The method of claim 8 , wherein the polypeptide comprises amino acids 1–60 of SEQ ID NO:2.
16. The method of claim 8 , wherein the polypeptide consists of amino acids 1–60 of SEQ ID NO:2.
17. The method of claim 1 , wherein the polypeptide comprises amino acids 1–60 of SEQ ID NO:2.
18. The method of claim 1 , wherein the polypeptide consists of amino acids 1–60 of SEQ ID NO:2.
