Rituximab therapy in patients with bullous pemphigoid: A retrospective study of 20 patients.

Abstract

Bullous pemphigoid (BP) is the most common autoimmune blistering disease requiring treatment with immunosuppressive medications; however, finding a therapy that has a sustained durable response and an acceptable side effect profile has been challenging. Our study aimed to evaluate the clinical outcomes of patients with BP treated with rituximab therapy at a single academic center. A retrospective chart review was performed on 20 patients who received at least 1 dose of rituximab therapy, either as initial therapy for severe BP or as therapy for recalcitrant disease after having failed conventional immunotherapies. Within our cohort, 75% of patients (n = 15) achieved remission an average of 169 days following rituximab therapy. There were no rituximab-related deaths and significantly fewer adverse events following rituximab therapy. This study was limited by its retrospective nature, focus on a single academic center, and small sample size. Use of rituximab therapy demonstrated high rates of remission, steroid-sparing activity, and an acceptable safety profile in our cohort of patients with severe BP or disease refractory to conventional therapies.
