title: [Atopic dermatitis and allergy].
abstract: Atopic dermatitis (AD) is a very common chronic inflammatory skin disease in childhood, often the first step in the atopic march. It seems justified to look for a food or a respiratory allergy, being worsening or responsible for the AD. At infant age, some clinical features are consistent with a food allergy: a severe AD, with an early onset, uncontrolled by topical corticosteroids, and a history of immediate-type reactions. As sensitization to food allergens is very common (positive skin prick-test, atopy patch-test or specific IgE), the role of food allergens in worsening AD is difficult to affirm. So, it could be necessary to ask the advice of an allergist, to avoid unnecessary elimination diets. At older age, exposure to aeroallergens cans worsen AD. Looking for an aeroallergen allergy can help to choose the specific immunotherapy, which clinical efficacy on AD seems interesting.
