Early apoptotic cells for use in treating sepsis
Compositions disclosed herein, and methods of use thereof included those for treating or preventing sepsis in a subject in need, including methods of extending of the survival of a subject suffering from sepsis, and reduction of organ dysfunction or failure due to sepsis. Methods of treating or preventing sepsis in a subject in need includes administering compositions comprising early apoptotic cells or early apoptotic cell supernatants. Compositions and methods of use thereof may reduce the negative proinflammatory effect accompanying sepsis. Further, anti-inflammatory cytokine release may be reduced. In certain instances, compositions may include additional agents.
1. A method of treating, preventing, inhibiting, reducing the incidence of, ameliorating, or alleviating, sepsis-related organ dysfunction, or any combination thereof, in a subject in need, comprising the step of administering a composition comprising an early apoptotic cell population to said subject, wherein said early apoptotic cells comprise peripheral blood mononuclear cells, wherein at least two organ systems are dysfunctional in said subject, and wherein said administering treats, prevents, inhibits, reduces the incidence of, ameliorates, or alleviates sepsis-related organ dysfunction in said subject.
2. The method of claim 1 , wherein sepsis comprises mild, severe, acute, or highly aggressive sepsis.
3. The method of claim 1 , wherein the survival of said subject is increased.
4. The method of claim 1 , wherein said method reduces the incidence of organ dysfunction.
5. The method of claim 1 , wherein organ dysfunction comprises multiple organ dysfunction or acute multiple organ dysfunction syndrome (MODS).
6. The method of claim 1 , wherein said early apoptotic cell population comprises
a mononuclear apoptotic cell population comprising a decreased of non-quiescent non-apoptotic cells, a suppressed cellular activation of any living non-apoptotic cells, or a reduced proliferation of any living non-apoptotic cells, or any combination thereof.
7. The method of claim 1 , wherein said early apoptotic cell population comprises a pooled population of early apoptotic cells.
8. The method of claim 1 , wherein said administration of the early apoptotic cell population is within 24 hours of initiation of sepsis.
9. The method of claim 1 , wherein said administering comprises a single infusion of said early apoptotic cell population or multiple infusions of said early apoptotic cell population, said composition comprising 40-240×10 6 cells/kg early apoptotic cells.
10. The method of claim 1 , wherein said administering comprises intra venal administration.
11. The method of claim 1 , further comprising administering an additional therapy.
12. The method of claim 11 , wherein said additional therapy is administered prior to, concurrent with, or following administration of said early apoptotic cells.
13. The method of claim 1 , wherein said method comprises a first-line therapy or an adjuvant therapy.
14. The method of claim 1 , wherein said method comprises rebalancing the immune response of said subject.
15. The method of claim 14 , wherein said rebalancing comprises reducing the secretion of one or more proinflammatory cytokine/chemokine, or reducing the secretion of one or more anti-inflammatory cytokines/chemokines, or a combination thereof.
16. The method of claim 1 , wherein said method prevents, inhibits, reduces the incidence of, or reduces the severity of a cytokine and chemokine storm in said subject.
17. The method of claim 1 , wherein said at least two organ systems are selected from kidney, lung, cardiovascular, and liver.
18. The method of claim 9 , wherein said composition comprises 140×10 6 ±20% cells/kg early apoptotic cells.
19. The method of claim 11 , wherein said additional therapy comprises administering an antibiotic.
20. The method of claim 19 , wherein said antibiotic is ertapenem.
