Methods for treatment or prevention of damage resulting from radiation, trauma or shock
Described herein are methods of treating a subject that has been or will be exposed to radiation, trauma or shock, the method comprising identifying a subject that has been or will be exposed to radiation, and treating the subject with a compound that treats, reduces the severity or delays the onset of sepsis or reduces the likelihood of mortality in a subject upon administration of a therapeutically effective amount the compound to the subject.
1. A method of treating oral mucositis in a subject that has been exposed to radiation, the method comprising administering to the subject an effective amount of an aqueous composition comprising:
a solubilized compound, wherein the compound is a compound of formula (I):
wherein:
n is an integer between 20 and 6000; and
each R 1 is independently selected for each occurrence from hydrogen, acetyl,
wherein at least 25% of R 1 substituents are H, at least 1% of R 1 substituents are acetyl, and at least 2% of R 1 substituents are
and wherein upon administration of the composition to the subject, the composition treats or reduces the severity of oral mucositis, thereby treating the subject.
2. The method of claim 1 , wherein the method treats or reduces the severity of oral mucositis from exposure to radiation relative to a subject not administered with the composition.
3. The method of claim 1 , wherein the radiation is from a dirty bomb, accidental nuclear incident or therapeutic radiation not related to the treatment of cancer.
4. The method of claim 1 , wherein the composition is administered orally.
5. The method of claim 1 , wherein the subject is treated within 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 8 hours, 10 hours, 12 hours, 16 hours, 20 hours, 24 hours, 2 days, 3 days, 4 days, 5 days, 6 days, 1 week, or 2 weeks after exposure to radiation.
6. The method of claim 1 , wherein the compound is functionalized at between 18% and 30%.
7. The method of claim 1 , wherein the molecular weight of the compound is from 40 to 120 kDa.
8. The method of claim 1 , wherein the polydispersity index of the compound is from 1.0 to 2.5.
9. The method of claim 1 , wherein the compound is provided in a dosage to provide up to 50 mg/kg.
10. The method of claim 1 , wherein the composition is administered from about 1 to about 3 times per day.
11. The method of claim 1 , wherein subject is treated for up to 6 weeks, 5 weeks, 4 weeks, 3 weeks, 2 weeks, 1 week, 6 days, 5 days, 4 days, 3 days, 2 days, or 1 day.
12. The method of claim 1 , wherein the composition is administered 1, 2, or 3 or more times every 1, 2, 3, 4, 5, or 6 days.
13. The method of claim 1 , wherein the composition is administered from about 1 to about 6 times per day.
14. The method of claim 1 , wherein the compound is soluble in aqueous solution from about pH 3 to about pH 9.
15. The method of claim 1 , wherein the compound is soluble in aqueous solution from about pH 6.8 to about pH 7.4.
