Identification of allergens by IgE-specific testing improves outcomes in atopic dermatitis.

ABSTRACT

INTRODUCTION: IgE quantitative assaying of allergens (IgEQAA) has long been implemented by allergists in determining patients' reactivities for allergic rhinitis and asthma, two of the three diagnoses in atopic syndrome. This test operates by measuring the patient's IgE response to different allergens and can identify potential triggers for a patient's symptoms. Despite this, IgEQAA has yet to see the same widespread use in the field of dermatology, specifically in the treatment of patients with atopic dermatitis (AD). MATERIALS AND METHODS: The affected body surface area (BSA) at first presentation, IgEQAA classes, and total immunoglobulin E (IgE) concentration were taken retrospectively for 54 patients with AD. RESULTS: Of the 54 patients observed, 41 had an abnormally high total IgE concentration (76%). Additionally, it was observed that nine (17%) of our patients significantly improved after making lifestyle changes. CONCLUSION: Knowledge of the identified specific antigens can guide patients to make lifestyle modifications that may improve disease outcomes. IgEQAA and avoidance of allergens may help some patients with AD.
