68 children with migraine were divided into 3 groups according the result of a skin-Prick test to food antigens. In group A (positivity to one or two antigens) (mean IgE level = 315 U/ml) 94.4% of the patients recovered from migraine in a two-months period of exclusion diet. In group B (positivity to 3 or more antigens) (mean IgE level = 226 U/ml) the same regimen lead to improvement 90% of migraineurs. In group C (skin-Prick test negative) (mean IgE level = 97 U/ml) a strictly oligoantigenic diet was proposed for 20 days. This was beneficial in only 17.2% of patients. Food allergy seems to play an important role in childhood migraine. Prick test appeared a useful and simple method to screen the patients.
