Generalized eczematous dermatitis and pruritus responsive to dupilumab in a patient with immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome.
Abstract
This case describes a patient with immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome with diffuse eczematous dermatitis and severe, intractable pruritus. Despite a bone marrow transplant and immunosuppressive therapy, his skin findings and pruritus persisted. Off-label dupilumab provided significant improvement and almost complete clearance of the dermatitis and pruritus. This is the first known report of dupilumab being used in a patient with IPEX syndrome.
