Aromatic-cationic peptides and methods for using same
The present disclosure provides methods of preventing or treating renal ischemia-reperfusion injury in a mammalian subject and methods for chronic treatment of ARVD, including administering an effective amount of an aromatic-cationic peptide to a subject in need thereof. The methods include administering aromatic-cationic peptides to prevent or treat renal injury during the treatment of renal artery stenosis. The methods include administering an effective amount of an aromatic-cationic peptide to subjects in need thereof.
1. A method for therapeutic treatment of atherosclerotic renal artery stenosis in a subject in need thereof, the method comprising administering to the subject a therapeutically effective amount of a peptide D-Arg-2′,6′-Dmt-Lys-Phe-NH 2 or a pharmaceutically acceptable salt thereof, and further comprising the step of performing a revascularization procedure on the subject, wherein the revascularization procedure comprises administration of one or more thrombolytic agents, and wherein the subject is administered the peptide prior to onset of renal microvasculature rarefaction.
2. The method of claim 1 , wherein the revascularization procedure comprises percutaneous transluminal renal angioplasty.
3. The method of claim 1 , wherein the subject is administered the peptide prior to the revascularization procedure, after the revascularization procedure, during and after the revascularization procedure, or continuously before, during, and after the revascularization procedure.
4. The method of claim 3 , wherein the subject is administered the peptide for at least 3 hours after the revascularization procedure, for at least 5 hours after the revascularization procedure, for at least 8 hours after the revascularization procedure, for at least 12 hours after the revascularization procedure, or for at least 24 hours after the revascularization procedure.
5. The method of claim 3 , wherein the subject is administered the peptide starting at least 8 hours before the revascularization procedure, starting at least 4 hours before the revascularization procedure, starting at least 2 hours before the revascularization procedure, starting at least 1 hour before the revascularization procedure, or starting at least 10 minutes before the revascularization procedure.
6. The method of claim 1 , wherein the revascularization procedure comprises removal of a renal artery occlusion.
7. The method of claim 1 , wherein the one or more thrombolytic agents are selected from the group consisting of: tissue plasminogen activator, urokinase, prourokinase, streptokinase, acylated form of plasminogen, acylated form of plasmin, and acylated streptokinase-plasminogen complex.
