Method for the treatment or prevention of infection-related immune conditions using a composition comprising IgM

1. A method for the treatment of sepsis in patients in need thereof, comprising:

administering a composition suitable for injection to said patient, said composition comprising immunoglobulin in a pharmaceutically acceptable carrier, wherein the immunoglobulin is at least 90% IgM.

2. The method according to claim 1 , characterized in that sepsis is produced by Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella pneumoniae, Streptococcus pneumoniae, Clostridium difficile, Clostridium botulinum , or combinations thereof.

3. The method according to claim 1 , characterized in that treatment of sepsis is performed through immunomodulation.

4. The method according to claim 3 , characterized in that immunomodulation is performed through inhibition of NF-κB induction, through the inhibition of proliferation of peripheral blood mononuclear cells or combination thereof.

5. The method according to claim 1 , characterized in that the composition has a 95% (w/v) of IgM purity.

6. The method according to claim 1 , characterized in that the administered dose of the composition is from 75 mg IgM/kg patient to 1 g IgM/kg patient.

7. The method according to claim 6 , characterized in that the composition is administered at least once a week.

8. The method according to claim 1 , characterized in that IgM is recombinant, plasma-derived, cell culture-derived, transgenic or chemically synthesized.

9. The method according to claim 8 , wherein IgM is plasma-derived IgM, isolated from a suitable fraction of plasma.

10. The method according to claim 1 , characterized in that the composition comprising IgM is administered alone.

11. The method according to claim 1 , characterized in that the composition comprising IgM is administered together with one or more other compositions or molecules selected from anti-inflammatory molecules, small molecule antibiotics, molecules that are antimicrobial in nature, natural or synthetic peptide antimicrobials, proteins with antimicrobial properties, other immunomodulators or combinations thereof.

12. The method according to claim 11 , characterized in that said other compositions or molecules are vancomycin, meropenem, lactoferrin or combinations thereof.

13. A method for the treatment of immune complications produced by an infection in patients in need thereof, comprising:

administering a composition suitable for injection to said patient, said composition comprising immunoglobulin in a pharmaceutically acceptable carrier, wherein the immunoglobulin is at least 90% IgM.

14. The method according to claim 13 , characterized in that the infection is produced by Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella pneumoniae, Streptococcus pneumoniae, Clostridium difficile, Clostridium botulinum , or combinations thereof.

15. The method according to claim 13 , characterized in that treatment of immune complications is performed through immunomodulation.

16. The method according to claim 15 , characterized in that immunomodulation is performed through the inhibition of NF-κB induction, through the inhibition of proliferation of peripheral blood mononuclear cells or combination thereof.

17. The method according to claim 13 , characterized in that the composition has a 95% (w/v) of IgM purity.

18. The method according to claim 13 , characterized in that the dose to be administered of the composition is from 75 mg IgM/kg patient to 1 g IgM/kg patient.

19. The method according to claim 18 , characterized in that the composition is administered at least once a week.

20. The method according to claim 13 , characterized in that IgM is recombinant, plasma-derived, cell culture-derived, transgenic, or chemically synthesized.

21. The method according to claim 20 , wherein the IgM is plasma-derived IgM, isolated from a suitable fraction of plasma.

22. The method according to claim 13 , characterized in that the composition comprising IgM is administered alone.

23. The method according to claim 13 , characterized in that the composition comprising IgM is administered together with one or more other compositions or molecules selected from anti-inflammatory molecules, small molecule antibiotics, molecules that are antimicrobial in nature, natural or synthetic peptide antimicrobials, proteins with antimicrobial properties, other immunomodulators or combinations thereof.

24. The method according to claim 23 , characterized in that said other compositions or molecules are vancomycin, meropenem, lactoferrin, or combinations thereof.
