Abstract
Background: Hypereosinophilic syndromes (HES) are defined as hypereosinophilia with eosinophil-related clinical manifestations, some of which overlap in presentation with asthma, atopic dermatitis, eosinophilic esophagitis, and/or chronic rhinosinusitis with nasal polyps. Dupilumab is approved to treat these conditions but can induce a transient rise in the absolute eosinophil count and rare eosinophil-related complications.
Objective: To determine whether eosinophil-related complications of dupilumab are increased in HES.
Methods: Retrospective chart review of patients with HES treated with dupilumab enrolled on an institutional review board-approved research protocol at the National Institutes of Health (NCT00001406) or receiving care at Walter Reed National Military Medical Center. Clinical response and treatment-emergent adverse events were recorded. Serum mediators were assessed in a subset of patients before and after dupilumab using stored samples.
Results: Among the 28 patients (15 male, 13 female; median age 41.5 y), the most common prescribing indication for dupilumab was chronic rhinosinusitis with nasal polyps (n = 11). Twenty-three patients (82%) showed significant clinical improvement on dupilumab. Hypereosinophilia (absolute eosinophil count > 1.5 × 109/L) recurred or worsened in 9 of 20 patients on dupilumab monotherapy. Moreover, 4 of 20 (20%) patients developed an eosinophil-related complication with dupilumab discontinuation and/or addition of eosinophil-lowering therapy. None of the 8 patients who received dupilumab while in hematological remission on an eosinophil-lowering biologic developed hypereosinophilia or an eosinophil-related complication. Serum immunoglobulin E and eotaxin levels decreased on dupilumab therapy.
Conclusions: These data suggest that dupilumab is effective in treating residual symptoms in HES patients but that the incidence of eosinophil-related complications is increased. Concomitant eosinophil-lowering therapy may reduce the risk of eosinophil-related complications during dupilumab therapy in patients with HES.
期刊介绍：
JACI: In Practice is an official publication of the American Academy of Allergy, Asthma & Immunology (AAAAI). It is a companion title to The Journal of Allergy and Clinical Immunology, and it aims to provide timely clinical papers, case reports, and management recommendations to clinical allergists and other physicians dealing with allergic and immunologic diseases in their practice. The mission of JACI: In Practice is to offer valid and impactful information that supports evidence-based clinical decisions in the diagnosis and management of asthma, allergies, immunologic conditions, and related diseases.
This journal publishes articles on various conditions treated by allergist-immunologists, including food allergy, respiratory disorders (such as asthma, rhinitis, nasal polyps, sinusitis, cough, ABPA, and hypersensitivity pneumonitis), drug allergy, insect sting allergy, anaphylaxis, dermatologic disorders (such as atopic dermatitis, contact dermatitis, urticaria, angioedema, and HAE), immunodeficiency, autoinflammatory syndromes, eosinophilic disorders, and mast cell disorders.
The focus of the journal is on providing cutting-edge clinical information that practitioners can use in their everyday practice or to acquire new knowledge and skills for the benefit of their patients. However, mechanistic or translational studies without immediate or near future clinical relevance, as well as animal studies, are not within the scope of the journal.
