Efficacy of Systemic Dapsone Treatment for Pyoderma Gangrenosum: A Retrospective Review.

Abstract

INTRODUCTION:

Pyoderma gangrenosum (PG) is a neutrophilic dermatosis commonly treated with steroid immunosuppression. The utility of dapsone as a non-immunosuppressive treatment for PG has been reported in case reports and series. We sought to evaluate the response and tolerability of concurrent systemic dapsone therapy for treating PG.

METHODS:

We reviewed PG patients treated with systemic dapsone at Massachusetts General Hospital and Brigham and Women's Hospital from 2000-2015. A treatment episode was defined as a minimum of 4 weeks of dapsone therapy with a documented response of complete, partial, or no improvement in wound healing.

RESULTS:

27 patients treated with systemic dapsone met inclusion criteria. 15.6% of treatment episodes demonstrated a response of complete healing, 81.3% of treatment episodes demonstrated a response of partial improvement, and 1 patient (3.1%) demonstrated no response. 9 patients (33.3%) had documented side effects of varying severity, with one (3.7%) requiring cessation of dapsone therapy.

DISCUSSION:

Systemic dapsone therapy may represent an effective and tolerable non-immunosuppressive adjuvant treatment for PG wound healing. J Drugs Dermatol. 2018;17(10):1058-1060.
