“…Based on the previous meta-analysis diabetic neuropathic ulcers had a mean healing rate of 42% at 20 weeks with standard care therapy alone [ 17 ]. The outcome has improved when compared to a study in 1999 (mean healing rate = 31%) [ 16 ].…”

Background Foot ulcer is a common complication of poorly controlled diabetes and peripheral vascular disease (PVD). The current standard of treatment for diabetic foot ulcers includes the management of underlying risk factors, wound debridement, use of antibiotics for infection, off-loading with cast, and revascularisation surgery. The glyceryl trinitrate (GTN) patch is currently off-licence in treating PVD or diabetic foot ulcers. This study aims to evaluate the effectiveness of the GTN patch in preventing amputation, improving pain control, and reducing the size of tissue loss (ulcer/gangrene) or localised ischaemic area. Method This is a pilot study of 30 patients who were started on the GTN patch from February 2020 to October 2021. Inclusion criteria were patients who have critical limb-threatening ischaemia (CLTI) and with no viable options or are at high risk for revascularisation, both endovascular and open surgery. Patients who were on a GTN patch for less than six weeks at the time of data collection or had unclear outcomes were excluded. The outcomes were retrospectively collected on prevention of amputation, improvement in pain control, and reduction in tissue loss (the size of ulcer/gangrene) or localised ischaemic area with the use of a GTN patch. The binomial test was used to compare the observed outcome of the GTN patch and the expected outcome, which was assumed to be 50% in this study. Results Ninety-three per cent (93%) of the patients who had GTN patches successfully avoided amputation (p<0.0001). Eighty-four per cent (84%) of patients reported better pain control (p=0.0022) and improvement in the size of ulcer/gangrene/localised ischaemic areas (p=0.0005). Conclusion The GTN patch is effective in preventing amputation, improving pain control, and reducing the size of ulcer/gangrene/localised ischaemic areas in patients who have end-stage CLTI and no viable options or who are at high risk for revascularisation surgery.

The treatment of diabetic foot ulcers is complex and costly with an increased risk for infection, which may even lead to amputation. This prospective case series aims to assess the effectiveness of a dehydrated amniotic membrane allograft combined with a bilayer dermal matrix for healing complicated foot ulcers in patients with comorbidities. A total of six patients with complicated full-thickness ulcers and comorbidities, such as diabetes and peripheral vascular disease were treated with this technique. Each wound was measured intraoperatively just before graft application, at 14 days after application, and then at weeks 4, 8, and 12. Changes in wound volume and area were compared over time. One patient had complete wound closure by week eight, a second patient by week 12. The other four patients had wounds that decreased in size during the course of 12 weeks. The mean decrease in wound volume was 73.5% post-removal of the bilayer dermal matrix after two weeks of application. At week 12, the mean decrease in wound area and volume were 93.2% and 97.1%, respectively. This case series provides initial evidence that the combination of dehydrated amniotic membrane allograft with bilayer dermal matrix promotes complete wound closure in patients with comorbidities that may impede wound healing. Further clinical trials are needed to confirm these results.

Diabetic foot ulcers: weekly versus second-weekly conservative sharp wound debridement

2023

Diabetic foot ulcers (DFU) are a serious and costly long-term complication of diabetes, and are one of the most prevalent hard-to-heal (chronic) wound types. Conservative sharp wound debridement (CSWD) is a mainstay of care. It is performed regularly until healing is achieved (when there is adequate blood flow for healing) to support endogenous healing and improve the efficacy of advanced healing therapies. CSWD is supported by evidence-based treatment guidelines, despite a lack of prospective studies. The first prospective randomised study to compare different frequencies of CSWD—the Diabetes Debridement Study (DDS)—showed no difference in healing outcomes at 12 weeks between those ulcers debrided weekly and those debrided every second week. A DFU may require more or less frequent debridement according to individual wound characteristics; however, the new data from DDS can inform clinical decisions and service provision. The implications of weekly versus second-weekly debridement are discussed.
