Methods of treating fungal infections
The invention relates to methods of treating a fungal infection in a subject in need thereof comprising administering to the subject a therapeutically effective amount of a composition comprising one or more antifungal peptides selected from the group consisting of BmKn2, dBmKn2, Kn2-7, and dKn2-7. Antifungal pharmaceutical compositions and dosage forms, including field-deployable dosage forms, comprising one or more of these antifungal peptides are also contemplated herein.
1. A method of treating a polymicrobial infection in a subject in need thereof comprising administering to the subject a therapeutically effective amount of a pharmaceutical composition comprising one or more peptides selected from the group consisting of BmKn2, dBmKn2, Kn2-7, and dKn2-7; wherein said BmKn2 and said Kn2-7 peptides comprise a combination of D form and L form amino acids.
2. The method of claim 1 , wherein the polymicrobial infection is resistant to one or more conventional anti-microbial drugs.
3. The method of claim 2 , wherein said one or more conventional anti-microbial drugs is one or more conventional antifungal agents.
4. The method of claim 1 , wherein the polymicrobial infection comprises infection with one or more pathogenic fungi and one or more additional microbes.
5. The method of claim 4 , wherein said one or more pathogenic fungi are resistant to one or more conventional anti-fungal agents.
6. The method of claim 4 , wherein said one or more pathogenic fungi are selected from the group consisting of Aspergillus; Blastomyces; Candida; Fusarium; Trichosporon; Penicillium; Coccidioides; Cryptococcus neoformans; Cryptococcus gattii; Histoplasma; Mucorales; Pneumocystis; Sporothrix; Trichophyton, Microsporum, Epidermophyton, Exserohilum , and Cladosporium.
7. The method of claim 6 , wherein said one or more pathogenic fungi is Candida.
8. The method of claim 7 , wherein the pathogenic fungi is Candida albicans.
9. The method of claim 4 , wherein the one or more additional microbes comprise bacteria and/or viruses.
10. The method of claim 4 , wherein the infection with one or more pathogenic fungi is a planktonic or a biofilm fungal infection, or a combination thereof.
11. The method of claim 10 , wherein the biofilm fungal infection comprises a pre-formed biofilm.
12. The method of claim 1 , wherein the polymicrobial infection is a wound infection.
13. The method of claim 1 , wherein the peptide is dKn2-7.
14. The method of claim 1 , wherein the pharmaceutical composition is administered alone, or in combination with a therapeutically effective amount of one or more additional pharmaceutically acceptable agents.
15. The method of claim 14 , wherein the one or more additional pharmaceutically acceptable agents is selected from the group consisting of an antimicrobial agent, an analgesic, an anesthetic, an anti-inflammatory agent, a hemostatic agent, an immunomodulator, a wound healing agent, a biofilm dispersal agent, and a biofilm inhibitor agent.
16. The method of claim 15 , wherein the wound healing agent is selected from the group consisting of pharmaceutical formulations comprising chitosan, antiseptics, antioxidants, vitamins, minerals, debriding agents, irrigants, hydrocolloids, alginates, hydrofibers, sodium chloride gels, hydroactive pastes, zinc, silver, cell proliferating agents, collagen, biological dressings, skin equivalents, keratinocytes, fibroblasts, platelet-rich plasma, honey, curcumin, papain and bromelain.
17. The method of claim 15 , wherein the antimicrobial agent is selected from the group consisting of an antifungal agent, an antibacterial agent, and an antiviral agent.
