Food hypersensitivity and dietary management in atopic dermatitis.
Although immune dysfunction is known to play an integral role in the development of atopic dermatitis, no clear delineation of the underlying pathogenic mechanism(s) responsible for this disorder has been proposed. Several factors are known to trigger flares of atopic dermatitis. In the extrinsic form of this disorder, food and airborne allergens may provoke flares of eczema. Research implicating food hypersensitivity in the pathogenesis of atopic dermatitis includes studies of food allergen avoidance in newborn infants at high risk for atopic disease, investigations of children with blinded food challenges, and therapeutic trials of allergen-elimination diets. Taken together, these studies demonstrate a significant pathogenic role for food hypersensitivity in about one-third of children with atopic dermatitis.
