Abstract

The present disclosure provides compositions, kits, and methods to protect organs by inducing acquired cytoresistance without causing injury to the organ. The compositions, kits, and methods utilize heme proteins, iron and/or vitamin B12 and, optionally, agents that impact heme protein metabolism.

Claims

1. A method of protecting an organ of a human patient from injury based on a scheduled insult comprising administering to the organ a therapeutically effective amount of (i) iron sucrose;

and (ii) a protoporphyrin, the therapeutically effective amount being administered before the scheduled insult to the organ occurs, wherein the administering protects the organ from the injury without causing injury to the organ.

2. The method of claim 1, wherein the protoporphyrin is a metal protoporphyrin.

3. The method of claim 2, wherein the metal protoporphyrin is Sn-protoporphyrin.

4. The method of claim 1, wherein the scheduled insult is surgery.

5. The method of claim 1, wherein the organ is a heart.

6. The method of claim 1, wherein the insult is chemotherapy.

7. The method of claim 1, wherein the insult is radiocontrast toxicity.

8. The method of claim 1, wherein the organ is a kidney.

9. The method of claim 1, wherein the organ is a liver.

10. The method of claim 1, wherein the organ is a lung.

11. The method of claim 1, wherein the iron sucrose and a protoporphyrin are administered at least 2 hours before the scheduled insult to the organ occurs.

12. The method of claim 1, wherein the iron sucrose and a protoporphyrin are administered at least 4 hours before the scheduled insult to the organ occurs.

13. The method of claim 1, wherein the iron sucrose and a protoporphyrin are administered at least 12 hours before the scheduled insult to the organ occurs.

14. The method of claim 1, wherein the iron sucrose and a protoporphyrin are administered at least 18 hours before the scheduled insult to the organ occurs.
