Use of dupilumab for recalcitrant bullous pemphigoid: A case report

Abstract

Bullous pemphigoid is an autoimmune blistering disease affecting the dermo-epidermal junction, most commonly seen in older patients. First-line treatment includes systemic, topical corticosteroids and/or steroid-sparing immunosuppressants. Treatment with these medications may be limited by their safety profile. Dupilumab is a humanized monoclonal antibody targeting interleukin-4 and interleukin-13 cytokines currently indicated for moderate-to-severe atopic dermatitis, severe asthma, chronic rhinosinusitis with nasal polyposis, and moderate-to-severe prurigo nodularis. We report a case of a patient with recalcitrant bullous pemphigoid effectively treated with dupilumab.
