Low-dose rituximab and concurrent adjuvant therapy for pemphigus: Protocol and single-centre long-term review of nine patients

Abstract

Pemphigus is an autoimmune B-cell mediated blistering disease associated with significant morbidity and mortality. Rituximab has proven effective for the treatment of steroid-refractory pemphigus, although there is controversy over the optimum dosing protocol. Additionally, effective disease control often requires long-term immunosuppression, even in disease-free periods. We present a case series of a single-centre long-term follow up of nine patients with pemphigus, treated with two 500-mg doses of rituximab separated by 14 days along with concurrent adjuvant therapy. In all these patients, low-dose rituximab resulted in B-cell depletion, along with a reduction in blistering disease. Three ..
