Improvement in Atopic Dermatitis and Recurrent Infection With Dupilumab in Children With Distinct Genetic Types of Hyper‐IgE Syndrome: A Case Series and Literature Review.

ABSTRACT Hyperimmunoglobulin E syndrome (HIES) is a group of rare genetic disorders characterized by severe atopic dermatitis and recurrent skin and pulmonary infections. The efficacy of dupilumab in pediatric patients with HIES‐associated severe atopic dermatitis is relatively understudied. Here, we present a series of three children with HIES, two with AD‐HIES caused by STAT3 mutations, and one with AR‐HIES caused by biallelic mutations in ZNF341. In all cases, dupilumab treatment led to sustained clearance of severe atopic dermatitis over multiple years, as well as improvements in systemic symptoms of HIES. [ABSTRACT FROM AUTHOR]
