Mycophenolate mofetil (MMF) has enjoyed increasing popularity as an emerging immunosuppressant treatment for various autoimmune dermatologic conditions, including pyoderma gangrenosum (PG).
The aim of this study was to examine the efficacy and safety of MMF as used in PG.
A retrospective chart review was conducted for all patients with PG treated with MMF at our institution (Victoria, Australia) for the past 11 years (2001-2012).
We identified 26 patients, 14 female and 12 male. Nine patients (34.6%) had associated systemic conditions. All patients received prednisolone. MMF was used as a first-line steroid-sparing agent in 11 patients (42.3%), second-line in 14 (53.8%), and third-line in 1 (3.85%). The average duration of treatment was 12.1 months. Fourteen patients experienced side effects (53.8%), although most were mild (26.9%). One patient died after a sigmoid colon perforation (3.85%). Overall 22 patients demonstrated clinical improvement during MMF treatment (84.6%). Thirteen patients achieved complete ulcer healing (50%), 10 while taking MMF and 3 after ceasing it.
This is a retrospective study based on a single-center cohort.
Our experience suggests that MMF is highly efficacious in PG together with prednisolone, or as part of combination therapy with other immunosuppressants.Le texte complet de cet article est disponible en PDF.
