Abstract

Background: Epidermolysis bullosa acquisita (EBA) is a rare subepidermal bullous disease. Long-term remission in this disease is difficult using current treatments, unlike that in patients with other autoimmune bullous diseases.Objective: We retrospectively evaluated the effectiveness and side effects of rituximab-intravenous immunoglobulin (IVIg) combination treatment in five patients with EBA resistant to conventional treatment.Patients and methods: Rituximab (375mg/m(2)) was administered for four consecutive weeks to four patients, and their treatment continued with IVIg at a dose of 2g/kg/month. One patient received two cycles of rituximab for three consecutive weeks, IVIg in the fourth week, followed by monthly IVIg administrations as in the other patients.Results: The total number of IVIg therapy cycles ranged from 10 to 26 (mean 19.4). Mean skin involvement, mucosal involvement, and disease severity scores decreased after a mean follow-up of 22.6 months (range, 10-28 months). In an analysis performed during months 24-28, the number of CD19-positive B cells was found to be below the normal reference range in four patients.Limitations: This was a retrospective study with a limited number of patients.Conclusion: Rituximab-IVIg combination treatment seems to be effective and safe for treating patients with EBA resistant to conventional treatments.
