A Systematic Evaluation of Dupilumab for Bullous Pemphigoid Treatment.

This paper systematically reviews the current articles regarding the use of dupilumab in the treatment of bullous pemphigoid (BP) to evaluate its safety and efficacy. PubMed, Embase, Cochrane Library, and Web of Science databases were searched for publications on dupilumab for BP from inception to 10 March, 2023. A total of 26 studies were included for systematic review. The primary outcome was clinical remission, and the secondary outcomes were recurrence and adverse events. Among 96 patients, 71.8% (n = 69/96) received systemic or topical steroids, immunosuppressants, immunomodulators, intravenous immunoglobulins, antihistamines, plasmapheresis, rituximab, and omalizumab, but none of them were successful. After dupilumab treatment, 66.7% (n = 64/96) of patients achieved complete remission, 25.0% (n = 24/96) had partial remission, 5.2% (n = 5/96) showed no remission, and no patients experienced deterioration. In addition, 1.0% (n = 1/96) and 2.0% (n = 2/96) patients stopped using dupilumab due to adverse reactions and cost, respectively. The average remission time was 4.5 months. 46.2% (n = 25/96) of the patients were followed up with a median follow-up of 8 months and only 2 patients relapsed at 8 and 7 months, respectively. Adverse event was 16.9% (n = 12/71), of which transient eosinophilia was the most common. This study indicates that the dupilumab is a promising treatment for BP with high clinical benefit associated with low recurrence rate, adverse event rate, and mortality. However, a large-scale randomized controlled trial is needed to further confirm the safety and efficacy of dupilumab in patients with BP treatment. [ABSTRACT FROM AUTHOR]
