Abstract

Bullous pemphigoid (BP) is an autoimmune blistering disorder that predominantly affects the elderly. Treatment regimens typically include topical and systemic immunosuppressive medications. Although effective, systemic corticosteroids are sometimes poorly tolerated in the elderly patient, contributing to the overall morbidity and mortality of BP. Dupilumab is a monoclonal antibody targeting interleukin 4 receptor alpha (IL4R?), approved for the treatment of atopic dermatitis, as well as moderate to severe asthma and chronic rhinosinusitis with nasal polyposis. In recent reports, dupilumab has been successfully used off-label to treat a variety of pruritic disorders, including chronic spontaneous urticaria [1], anal and genital itch [2], allergic contact dermatitis [3], and prurigo nodularis [4, 5]. We report here a case of an elderly patient with refractory BP whose symptoms of pruritus and blistering became well-controlled with the addition of dupilumab to the treatment regimen.
