ABSTRACT
BACKGROUND:
Lower extremity wounds in patients with diabetes are difficult to heal due to an overabundance of pro-inflammatory M1 macrophages, reduced phagocytosis of necrosed cells, and circulatory issues. Keratin biomaterials have been shown to address some of these concerns by encouraging the proliferation of anti-inflammatory M2 macrophages, thereby creating more favorable conditions for wound healing resembling those of patients without diabetes.OBJECTIVE:
To investigate the effect of a novel human keratin matrix (HKM) on wound healing. MATERIALS ANDMETHODS:
Ten patients with diabetes with lower extremity wounds at risk for delayed healing underwent wound debridement and application of HKM. Patients received weekly follow-up care and reapplication of HKM until healing occurred; wound size at each visit was used to calculate healing rate.RESULTS:
Increased healing rates were noted with HKM compared with standard of care (SOC), including debridement and collagen treatment in all 8 patients who had received SOC prior to HKM treatment. When HKM treatment was alternated with SOC in 2 patients due to other medical conditions, healing rates decreased with SOC and then increased after reintroduction of HKM applications.CONCLUSIONS:
These results suggest that HKM may help regulate the pathological processes that contribute to wound chronicity to "kick-start" wound healing. This case series demonstrates that HKM is a promising technology to improve healing rates in nonhealing lower extremity wounds in patients with diabetes.
