Collagen-Based Regenerative Therapy in a Critical Ischemic Diabetic Foot Ulcer: A Limb-Salvaging Case Report.
A 58-year-old man with diabetes, end-stage kidney disease, and severe peripheral artery disease had a chronic foot ulcer that would not heal despite a year of standard care. Doctors in Palestine tried an injectable collagen-based regenerative therapy, which is a substance that helps the body rebuild tissue. Within three months, the wound completely closed, and the leg was saved from amputation. Later, a burn caused the wound to reopen, but after revascularization surgery to improve blood flow, the healing held. This case suggests that collagen-based therapy may offer a new option for hard-to-heal diabetic foot ulcers, especially when blood flow is poor. However, because this is a single case, more research is needed to confirm its effectiveness and safety in larger groups.
Key takeaways
- A diabetic foot ulcer with poor blood flow healed completely in three months after injectable collagen therapy, saving the patient's leg from amputation.
- The patient had multiple complicating conditions, including kidney failure, yet the therapy still promoted wound closure.
- A burn later caused the wound to reopen, but revascularization surgery helped it heal again, showing the need for ongoing care.
- For patients, this highlights the possibility of new regenerative treatments beyond standard wound care, but they should discuss eligibility with a specialist.
- Ask your doctor: 'Is collagen-based regenerative therapy an option for my non-healing ulcer, and what does it involve?', and 'What are the risks and costs compared to standard care?'
Editor's note
In China, diabetic foot ulcer management is evolving, with specialized centers increasingly adopting advanced therapies like growth factors and skin substitutes. Injectable collagen-based regenerative therapy is not yet widely available but represents a promising frontier. Patients with critical ischemia should seek multidisciplinary care, including revascularization, and ask about emerging regenerative options.
