TLDR
Wound debridement is a vital adjunct in the care of patients with chronic diabetic foot ulcers and for any given center, the percentage of patients who healed was greater with rhPDGF than placebo, but in general, a lower rate of healing was observed in those centers that performed less frequent debridements.Abstract:
Background There has been a broad interest in the use of growth factors to treat patients with chronic nonischemic diabetic ulcers. Study design One hundred eighteen patients were studied in a randomized, prospective, double-blind, multicenter trial comparing treatment with topically applied recombinant human platelet-derived growth factor (rhPDGF) or placebo (vehicle) and were treated until completely healed or to 20 weeks. All patients had aggressive sharp debridement of their ulcers before randomization and repeat debridement of callus and necrotic tissue as needed. The influence of debridement was evaluated by reviewing the records of the office visits where debridement was performed. Results Forty-eight percent of patients treated with rhPDGF healed compared with 25 percent of patients who received placebo (p = 0.01). The mean percentage of office visits where debridement was performed was comparable for the two treatment groups: 46.8 percent (rhPDGF) and 48.0 percent (placebo). In general, a lower rate of healing was observed in those centers that performed less frequent debridement. The improved response rate observed with more frequent debridement was independent of the treatment group. However, for any given center, the percentage of patients who healed was greater with rhPDGF than placebo. Conclusions Wound debridement is a vital adjunct in the care of patients with chronic diabetic foot ulcers.read more

TL;DR: The greatest need is for agents that enhance insulin sensitivity, halt the progressive pancreatic β-cell failure that is characteristic of T2DM and prevent or reverse the microvascular complications.

TL;DR: In this issue of the JCI, Gallagher and colleagues demonstrate that in diabetic mice, hyperoxia enhances the mobilization of circulating endothelial progenitor cells (EPCs) from the bone marrow to the peripheral circulation, resulting in accelerated wound healing.
