Abstract
Food allergy in atopic dermatitis is mediated by complex immune interactions between genetics, diet, environment, and the microbiome. When contact between inflamed skin and food antigens occurs, contact hypersensitivity can develop. Consequently, systemic contact dermatitis (SCD) can occur after ingestion of allergenic foods or food additives in the setting of a Th2 response with CLA-positive T cells, triggering dermatitis where skin resident memory lymphocytes reside. This phenomenon explains food-triggered dermatitis. Atopy patch tests (APTs) detect sensitization to food proteins responsible for SCD, which in turn can be confirmed by oral food challenge with delayed interpretation. We summarize the literature on using APTs to identify foods for oral challenge with dermatitis as an outcome. In dermatitis patients at risk for Th2 skewing based on a history of childhood-onset flexural dermatitis, shared decision-making should include a discussion of identifying and avoiding food and food additive triggers, as well as identifying and avoiding all contact allergens, prior to initiation of systemic therapy for dermatitis.
期刊介绍:
Clinical Reviews in Allergy & Immunology is a scholarly journal that focuses on the advancement of clinical management in allergic and immunologic diseases. The journal publishes both scholarly reviews and experimental papers that address the current state of managing these diseases, placing new data into perspective. Each issue of the journal is dedicated to a specific theme of critical importance to allergists and immunologists, aiming to provide a comprehensive understanding of the subject matter for a wide readership.
The journal is particularly helpful in explaining how novel data impacts clinical management, along with advancements such as standardized protocols for allergy skin testing and challenge procedures, as well as improved understanding of cell biology. Ultimately, the journal aims to contribute to the improvement of care and management for patients with immune-mediated diseases.
