Skin and stool microbiota in children with food allergy. Tracing the skin and stool microbiota in children with food allergy in the first 3 years of life

Food allergy (FA) affects up to 10 % of children, especially children with atopic dermatitis (AD). During infancy, skin and gut microbiome may determine both the course of FA and the tolerance to food allergy, like colonization with Staphylococcus aureus have a higher risk of persisting egg and peanut allergy. This colonialization might play a role in the dysfunction of the skin barrier and therefore play a role in allergic sensitization. We investigated the development of gut and skin microbiome in children after their first allergic reaction over time. Understanding of the impact of the microbiome on the clinical course of FA and AD may allow for the development of new models of allergy treatment and prevention.
