Kids With Food-Triggered Eczema Are at Risk for Developing Life-Threatening Food Allergy

27 maggio 2016 - 10:03Rassegna stampa

Elimination of the food that triggers atopic dermatitis is associated with increased risk of developing immediate reactions to that food, according to a study published in the Journal of Allergy and Clinical Immunology.

Immediate reactions to the culprit food range from hives to life-threatening anaphylaxis.

"Our findings suggest that families of children diagnosed with food-triggered atopic dermatitis should be prepared to respond to a full-blown food allergy reaction if the child is accidentally exposed to the food in question," said senior author Anne Marie Singh, MD, Ann & Robert H. Lurie Children's Hospital of Chicago, Chicago, Illinois. "These children need an emergency action plan and an injectable epinephrine to keep them safe."

The study followed 298 patients with food-triggered atopic dermatitis. A total of 19% of these patients, who had no history of immediate food reactions, developed food allergy after being placed on an elimination diet. Nearly one-third of the new immediate food reactions included anaphylaxis.

Foods are a trigger in up to 30% of patients with moderate-to-severe atopic dermatitis, mostly in infants and children aged younger than 5 years. While these children typically are instructed to avoid the triggering food completely, this recommendation might need to be modified.

"Given that in our study strict elimination diets as management for atopic dermatitis clearly increased the risk of immediate reactions, more research is needed to see if children may benefit from keeping tolerable amounts of the food allergen in their diet," said Dr. Singh. "Families should work with an allergist to determine the optimal treatment course for their child.

More research is needed to establish if letting children with atopic dermatitis eat tolerable amounts of allergenic food would prevent the development of immediate reactions to that food.
