BACKGROUND: High epitope diversity has been associated with increased IgE-mediated food allergy severity.
OBJECTIVE: To characterize associations between results from an automated microarray system and self-reported food allergy and food-triggered atopic dermatitis (AD).
METHODS: Families with food allergic children were identified from a Jewish community in Lakewood, New Jersey, with immediate family members without food allergy or food-triggered AD serving as controls for the identified children. Sets of microarray components analyzed were to milk (Bos d 4, Bos d 5, Bos d 8, Bos d lactoferrin), egg (Gal d 1, Gal d 2, Gal d 3, Gal d 5), and peanut (Ara h 1, Ara h 2, Ara h 3, Ara h 6).
RESULTS: Seventy-three patients from 23 families were recruited. Culprit foods included milk (n = 20), egg (n = 10), and peanut (n = 6) for food allergy and milk (n = 10) and egg (n = 7) for food-triggered AD. Odds of having had a self-reported related food allergy or food-triggered AD reaction significantly increased with a higher number of detectable microarray components to that food. Ara h 1, Ara h 2, and Ara h 6 were individually associated with reported peanut allergy, and Bos d 4 was individually associated with reported milk allergy. The number of egg components significantly increased the odds of having related food-triggered AD.
CONCLUSION: High diversity of food allergen components relates well to self-reported history of food allergy and food-associated AD.
