Intravenous immunoglobulin treatment for refractory pyoderma gangrenosum.
Australasian Journal of Dermatology 2023 May
BACKGROUND: Intravenous immunoglobulins (IVIG) have been increasingly used for various inflammatory dermatoses with success. Small case series and case reports suggest a role for IVIG in the management of refractory pyoderma gangrenosum (PG).
OBJECTIVE: The objective was to study the characteristics of PG patients treated with IVIG and the efficacy and safety of IVIG for patients with refractory PG.
METHODS: An analysis was performed of all patients with PG treated with IVIG from 2012 to 2022 at an Australian tertiary hospital seeing a high volume of PG patients.
RESULTS: We identified 12 patients, 9 females and 3 males, with median age of 61 years (29-77) at IVIG commencement. All patients were taking systemic corticosteroid therapy prior to IVIG treatment, and all had been treated with a steroid-sparing agent-including ten patients who had been treated with a biologic agent. IVIG was used with corticosteroids in one patient, concurrently with a steroid-sparing agent in nine patients and with a biologic agent in eight patients. Eleven patients demonstrated treatment response to IVIG-six with excellent response and five with good response. Three patients had complete healing of their most active ulcer. One patient did not respond to IVIG. Nine patients were able to wean their prednisolone dose and one patient was able to cease prednisolone. Four adverse events were recorded, and only one patient had to cease treatment due to aseptic meningitis and headaches.
CONCLUSION: Our experience suggests that IVIG may be an efficacious treatment for patients with refractory PG due to its pleiotropic and immunomodulatory effects, particularly for patients with malignancy or other systemic conditions where high-dose immunosuppressive agents are contraindicated.
