What Researchers Did
Researchers investigated the modifications in wound expression of HIF-1α, NF-κB, IGFBP-3, and VEGF, and circulating inflammatory cytokines in 18 patients with Grade 3 or 4 diabetic foot ulcers treated with hyperbaric oxygen therapy.
What They Found
All 18 patients experienced complete ulcer healing after one month of hyperbaric oxygen therapy, with no relapses reported at the one-year follow-up. The treatment also resulted in significant modifications in VEGF expression and a shift in HIF-1α and NF-κB localization from the nucleus to the cytoplasm.
What This Means for Canadian Patients
For Canadian patients suffering from severe diabetic foot ulcers, hyperbaric oxygen therapy could be a valuable adjunctive treatment to promote wound healing and prevent recurrence. This may help improve patient outcomes and reduce the risk of amputation.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada or with Canadian participants.
Study Limitations
A significant limitation of this study is its very small sample size of 18 patients and the absence of a control group for comparison.
