Use of thrombin-derived peptides for the therapy of chronic dermal ulcers
Disclosed is a method of promoting healing of a chronic dermal skin ulcer, such as a diabetic ulcer, on a subject. The method comprises the step of contacting the chronic dermal skin ulcer with an effective amount of an agonist of the non-proteolytically activated thrombin receptor.
1. A method of treating a chronic ulcer below the kneecap in a diabetic subject in need of treatment, said method comprising administering to the ulcer an effective amount of the polypeptide Ala-Gly-Tyr-Lys-Pro-Asp-Glu-Gly-Lys-Arg-Gly-Asp-Ala-Cys-Glu-Gly-Asp-Ser-Gly-Gly-Pro-Phe-Val-NH 2 (SEQ ID NO:6), wherein the polypeptide is administered to the ulcer alone or in combination with an antimicrobial, a disinfectant, an antibiotic, an analgesic or an anti-inflammatory agent.
2. A method of treating a decubitus ulcer in a subject in need of treatment, said method comprising administering to the ulcer an effective amount of the polypeptide Ala-Gly-Tyr-Lys-Pro-Asp-Glu-Gly-Lys-Arg-Gly-Asp-Ala-Cys-Glu-Gly-Asp-Ser-Gly-Gly-Pro-Phe-Val-NH 2 (SEQ ID NO:6), wherein the polypeptide is administered to the ulcer alone or in combination with an antimicrobial, a disinfectant, an antibiotic, an analgesic or an anti-inflammatory agent.
3. A method of treating a chronic ulcer below the kneecap in a diabetic subject in need of treatment, said method comprising administering to the ulcer an effective amount of the polypeptide Ala-Gly-Tyr-Lys-Pro-Asp-Glu-Gly-Lys-Arg-Gly-Asp-Ala-Cys-Glu-Gly-Asp-Ser-Gly-Gly-Pro-Phe-Val-NH 2 (SEQ ID NO:6), wherein the polypeptide is administered to the ulcer alone or in combination with an antimicrobial, a disinfectant, an antibiotic, an analgesic or an anti-inflammatory agent, the method further comprising debriding the ulcer, cleansing the ulcer, dressing the ulcer, and offloading pressure from the ulcer.
4. A method of treating a decubitus ulcer in a subject in need of treatment, said method comprising administering to the ulcer an effective amount of the polypeptide Ala-Gly-Tyr-Lys-Pro-Asp-Glu-Gly-Lys-Arg-Gly-Asp-Ala-Cys-Glu-Gly-Asp-Ser-Gly-Gly-Pro-Phe-Val-NH 2 (SEQ ID NO:6), wherein the polypeptide is administered to the ulcer alone or in combination with an antimicrobial, a disinfectant, an antibiotic, an analgesic or an anti-inflammatory agent, the method further comprising debriding the ulcer, cleansing the ulcer, dressing the ulcer, and offloading pressure from the ulcer.
5. A method of treating a chronic ulcer below the kneecap in a diabetic subject in need of treatment, said method comprising administering to the ulcer an effective amount of the polypeptide Ala-Gly-Tyr-Lys-Pro-Asp-Glu-Gly-Lys-Arg-Gly-Asp-Ala-Cys-Glu-Gly-Asp-Ser-Gly-Gly-Pro-Phe-Val-NH 2 (SEQ ID NO:6), wherein the polypeptide is administered to the ulcer for a period of at least 32 days, alone or in combination with an antimicrobial, a disinfectant, an antibiotic, an analgesic or an anti-inflammatory agent.
6. Method of treating a decubitus ulcer in a subject in need of treatment, said method comprising administering to the ulcer an effective amount of the polypeptide Ala-Gly-Tyr-Lys-Pro-Asp-Glu-Gly-Lys-Arg-Gly-Asp-Ala-Cys-Glu-Gly-Asp-Ser-Gly-Gly-Pro-Phe-Val-NH 2 (SEQ ID NO:6), wherein the polypeptide is administered to the ulcer for a period of at least 32 days, alone or in combination with an antimicrobial, a disinfectant, an antibiotic, an analgesic or an anti-inflammatory agent.
