Reversing or preventing premature vascular senescence
Premature vascular senescence is reversed or prevented in tissue or cells by contacting the tissue or cells with a hydroxyguanidine. This finds application in treatment of patients with a disorder associated with elevated levels of advanced glycation end products in blood or tissue, e.g., patients with end stage renal disease or poorly controlled diabetes, and in contacting vascular tissue or cells ex vivo to prevent occurrence of premature senescence.
1. A method of treating an animal with elevated levels of advanced glycation end products in blood or tissue comprising administering to the animal a therapeutically effective amount of agent which is selected from the group consisting of premature vascular senescence ameliorating hydroxyguanidines selected from the group consisting of hydroxy-L-arginine and hydroxyguanidine and pharmaceutically acceptable salts thereof
2. The method of claim 1 where the animal is affected with end stage renal disease.
3. The method of claim 1 where the animal is affected with poorly controlled diabetes.
4. The method of claim 1 where the animal is affected with chronic renal disease.
5. The method of claim 1 where the animal is affected with peripheral vascular disease.
6. The method of claim 1 where the animal is affected with systemic lupus erythematosis.
7. The method of claim 1 where the animal is affected with Alzheimer's disease.
8. The method of claim 1 where the animal is affected with a disorder selected from the group consisting of end stage renal disease, chronic renal disease, poorly controlled diabetes, peripheral vascular disease, systemic lupus erythematosis and Alzheimer's disease.
9. The method of claim 8 wherein the agent comprises hydroxy-L-arginine.
10. The method of claim 8 wherein the disorder is selected from the group consisting of end stage renal disease, chronic renal disease, perpheral vascular disease and systemic lupus erythematosis.
11. The method of claim 10 where the agent comprises hydroxy-L-arginine.
