Children with More Severe Eczema Less Likely to Outgrow Milk, Egg Allergy

“While our clinical impression has been that the natural course of food allergy might be related to co-existing atopic dermatitis, previous studies had not provided any clear answers to this important question,” explained study author Robert A. Wood, MD, FAAAAI.

Researchers from Duke, Johns Hopkins, Mount Sinai, National Jewish, the National Institute of Allergy and Infectious Diseases (NIAID) and the University of Arkansas enrolled over 500 children between the ages of 3 and 15 months. The participating children had either a convincing history of egg or milk allergy with a positive prick skin test to the trigger food and/or moderate-severe atopic dermatitis and a positive prick skin test to milk or egg.

Eczema severity was scored at baseline and 2 years and was analyzed categorically as none-mild or moderate-severe. Milk and egg allergy was based upon clinical history and food-specific IgE with resolution established by successful ingestion of the trigger food.

During 2 years of observation, 46% of children with none-mild eczema at enrollment outgrew their milk allergy versus only 25% of the children enrolled with moderate-severe eczema. Interestingly, improved eczema severity was not associated with food allergy resolution. Among those with moderate-severe eczema at enrollment who improved to none-mild, just 19% resolved their food allergy compared to 32% who remained moderate-severe.

When looking at egg allergy, 39% of children with none-mild eczema at enrollment outgrew their egg allergy versus 21% that were enrolled with moderate-severe eczema. Of those children who had moderate-severe eczema at enrollment who improved to none-mild over 2 years, 28% resolved their allergy compared with 22% who remained moderate-severe.

“These findings will help clinicians caring for infants with eczema and milk or egg allergy and provide more accurate advice to parents about the likely course of their child’s milk or egg allergy,” added Wood.
