Classification and treatment of chronic nonhealing wounds. Successful treatment with autologous platelet-derived wound healing factors (PDWHF).


Previous animal data showed that platelets contain growth factors that stimulate capillary endothelial migration (angiogenesis), fibroblast proliferation and migration, and collagen synthesis. This study utilized autologous platelet-derived wound healing factors (PDWHF) to treat 49 patients with chronic nonhealing cutaneous ulcers. Patients were classified on the basis of 20 clinical and wound status parameters to generate a wound severity index. Forty-nine patients--58% diabetic (20% with renal transplants); 16% with trauma, vasculitis, etc.; 14% with decubitus ulcers; and 6% each with venous stasis or arterial insufficiency--with a total of 95 wounds had received conventional wound care for an average of 198 weeks (range: 1-1820 weeks). After informed consent was obtained, patients received autologous PDWHF. Mean 100% healing time for all patients was 10.6 weeks. There was no abnormal tissue formation, keloid, or hypertrophic scarring. A multivariant analysis showed a direct correlation to 100% healing with initial wound size and the initiation of PDWHF therapy. This is the first clinical demonstration that locally acting growth factors promote healing of chronic cutaneous ulcers.
