Abstract
OBJECTIVE: Diabetic wounds that do not heal completely usually exhibit inflammatory markers, increased protease activity, and reduced levels of growth factors and cell count. A systematic review was performed to determine whether there is enough evidence to support the use of an oxidized regenerated cellulose/collagen matrix (ORC+C) to treat diabetic foot ulcers (DFUs). METHODS: Study authors analyzed randomized controlled trials (RCTs) on ORC+C dressings for the treatment of DFUs. A literature search was conducted for all available reports of relevant studies published in journals indexed in PubMed, LILACS, and SciELO databases. There were no restrictions based on date of publication. A population-intervention-comparison-outcome framework was built on MeSH terms and keywords. Two independent researchers analyzed all articles for data collection and used the Cochrane Collaboration tool for risk-of-bias assessment. RESULTS: At first, 316 related studies were located in the databases. After evaluating these studies for methodological similarities, only 3 were considered eligible for the review. One RCT was considered at high risk of bias. Results from this meta-analysis of 2 studies showed no significant improvement in wound healing rates of DFUs when ORC+C was compared with standard wound care. CONCLUSIONS: Because of several methodology flaws in the reviewed studies, these results suggest that there is currently no research evidence to suggest that the use of ORC+C improves wound healing rates of DFUs. Additional research with high-quality RCTs focused on diabetic ulcers is necessary.
