Abstract
Chronic diabetic wounds are a significant issue that can be treated with topical hydrogel therapies. The aim of this study was to review the different compositions of hydrogel that have been developed and analyze their clinical relevance in the treatment of chronic diabetic wounds.
Methods
We conducted a scoping review in which twelve articles were selected for review after applying relevant inclusion and exclusion criteria using a two-reviewer strategy. Data extracted from these studies was used to answer the following research question: What is the composition of hydrogels used to treat chronic diabetic wounds and how effective are they?
Results
We analyzed five randomized controlled trials, two retrospective studies, three reviews, and two case reports. Hydrogel compositions discussed included mesenchymal stem cell sheets, carbomer, collagen, and alginate hydrogels, as well as hydrogels embedded with platelet-derived growth factor. Synthetic hydrogels, largely composed of carbomers, were found to have high levels of evidence supporting their wound healing properties, though few articles described their routine use in a clinical setting. Collagen hydrogels dominate the present-day hydrogel market in the clinical treatment of chronic diabetic wounds. The augmentation of hydrogels with therapeutic biomaterials is a new field of hydrogel research, with studies demonstrating promising early in vitro and in vivo animal studies demonstrating promising early results for in vitro and in vivo animal investigations.
Conclusions
Current research supports hydrogels as a promising topical therapy in the treatment of chronic diabetic wounds. Augmenting Food & Drug Administration-approved hydrogels with therapeutic substances remains an interesting early area of investigation.
