Abstract
BACKGROUND: Bullous pemphigoid is an autoimmune blistering skin disease that predominantly affects the elderly. Conventional therapy using high-dose systemic corticosteroids and immunosuppressive agents can be ineffective in some patients and produce adverse events and relapses. Hence, alternate therapies are required. OBJECTIVE: The clinical outcomes of patients with extensive, recalcitrant bullous pemphigoid treated with a combination therapy of rituximab (RTX) and intravenous immunoglobulin were evaluated. METHODS: In this retrospective study, 12 patients (mean age of 68.25 years) unresponsive to previous conventional immunosuppressive therapy, intravenous immunoglobulin, and/or RTX were treated with this combination therapy. RESULTS: Complete clinical resolution occurred in a mean of 4.6 months and previous systemic therapy was discontinued in 6.2 months. Two patients had a recurrence posttherapy and responded to additional RTX infusions. The remaining 10 patients had no recurrences. Patients were followed up for a mean of 73.8 months after discontinuation of all systemic therapy. All have remained in remission without adverse events for 6 years. LIMITATIONS: This was a retrospective study with a small sample size. CONCLUSION: The combination of RTX and intravenous immunoglobulin produced a sustained clinical remission without adverse events, infections, and hospitalizations. This specific combination protocol offers a promising therapy for patients with recalcitrant bullous pemphigoid.
