ABSTRACT
Pyoderma gangrenosum (PG) is a rare, chronic, ulcerative disease characterized by non-healing wounds that worsen with debridement, a phenomenon called pathergy. No consensus regarding pathogenesis, diagnosis, or treatment exists for PG. A previous pilot study using dehydrated human amniotic/chorionic membrane (dHACM), following excisional debridement, augmented PG wound healing and allowed for subsequent wound closure through split-thickness skin grafting (STSG). In this clinical trial (NCT05120726), four patients with an established PG diagnosis were enrolled to undergo treatment with dHACM and characterize the pre- and post-treatment transcriptome profiles. RNA sequencing was used to isolate the total RNA from specimens. Genes of particular interest were quantified through real-time quantitative reverse transcription polymerase chain reaction. We observed varied changes to the local expression of inflammatory response, positive regulators of cellular proliferation, and extracellular matrix disassembly cytokines. All PG wounds produced granulation tissue following treatment and were closed using split-thickness skin grafts.
