Main idea: Compared with standard of care, acellular dermal matrix may accelerate the healing velocity of uninfected, non-ischemic, full-thickness diabetic foot ulcer. Acellular dermal matrix showed superiority compared with standard of care alone, while generating no more complications.
Background: Diabetic foot ulcer(DFU) is a chronic, refractory disease in need of multidisciplinary endeavour, miscellaneous strategies have been adopted to address this annoying issue, including acellular dermal matrix/negative pressure wound therapy/standard of care (SOC) etc. However, consensus has not been reached. As a promising procedure, the efficacy and safety of ADM remains controversial. We therefore performed a meta-analysis of randomized controlled trials (RCTs) to compare the efficacy and safety of acellular dermal matrix to standard of care in DFU.
Results: A total of 632 DFU patients from 6 RCTs were subjected to meta-analysis. The results showed that compared with the merely SOC, the complete healing rate in acellular dermal matrix group was higher both at 12 weeks and 16 weeks . The mean time to complete wound healing was shorter in acellular dermal matrix group. The occurrence of adverse event in both groups showed no significant difference.
