Pyoderma gangrenosum (PG) is a rare, painful neutrophilic dermatosis characterized by rapidly progressing skin ulcers. Despite the importance of local wound care in managing PG, there is no consensus or evidence-based guidelines. This systematic review aimed to investigate local wound care strategies for PG. A comprehensive search of Embase, MEDLINE, and the Cochrane Library yielded 1213 references, from which 269 studies were included, covering 351 patients. The most reported treatment methods included sharp debridement (11%), topical corticosteroids (27%) and non-adherent dressings (12%). However, no clear correlation between these treatments and healing outcomes was found likely due to confounding factors such as varied wound sizes, superinfection and inconsistent reporting. Additionally, directed wound care regimens have not been able to show statistical significance for healing outcomes. Our study describes the current local wound care landscape and underscores a critical gap in the current literature regarding standardized treatment protocols for PG., (© 2024 The Author(s).

This study assesses the impact of a processed microvascular tissue (PMVT) allograft on wound closure and healing in a prospective, single-blinded, multi-centre, randomised controlled clinical trial of 100 subjects with Wagner Grade 1 and 2 chronic neuropathic diabetic foot ulcerations. In addition to standard wound care, including standardised offloading, the treatment arm received PMVT while the control arm received a collagen alginate dressing. The primary endpoint was complete wound closure at 12 weeks. Secondary endpoints assessed on all subjects were percent wound area reduction, time to healing, and local neuropathy. Novel exploratory sub-studies were conducted for wound area perfusion and changes in regional neuropathy. Weekly application of PMVT resulted in increased complete wound closure at 12 weeks (74% vs 38%; P = .0003), greater percent wound area reduction from weeks four through 12 (76% vs 24%; P = .009), decreased time to healing (54 days vs 64 days; P = .009), and improved local neuropathy (118% vs 11%; P = .028) compared with the control arm. Enhanced perfusion and improved regional neuropathy were demonstrated in the sub-studies. In conclusion, this study demonstrated increased complete healing with PMVT and supports its use in treating non-healing DFUs. The observed benefit of PMVT on the exploratory regional neuropathy and perfusion endpoints warrants further study., (© 2021 The Authors.
