Updates in innovation of the treatment of pyoderma gangrenosum.

Abstract

Introduction: Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis characterized by rapidly enlarging, painful ulcers with undermined borders. The management of PG is challenging due to the lack of standardized evidence-based treatments.

Areas covered: This review examines recent efforts to establish standardized outcomes for clinical trials to facilitate the drug development process for PG. It explores new therapeutics in development and evaluates advanced options for wound and pain management. Literature available on the pathogenesis, treatment, and pain management of PG from database inception to April 2024 was searched in PubMed, Embase, and Cochrane. Clinicaltrials.gov and the EU Clinical Trials Register were searched for clinical trials on PG.

Expert opinion: New therapeutics such as interleukin 36 inhibitor and complement component C5a inhibitor more specifically target key pathways in the pathogenesis of PG have shown promise and can greatly benefit patients with PG, which still lacks an FDA-approved treatment. In addition to systemic therapy, local wound care and pain management should be carried out simultaneously to achieve successful wound healing.
