Total IgE, Specific IgE and Prick-Tests Against Foods in Common Migraine—A Prospective Study

Abstract
A prospective study of total IgE, specific IgE against 12 common foods, and prick-tests with 11 common food allergens was performed on 50 consecutive migraine sufferers. Total IgE levels were found above 100 kU/I for seven patients, but five of them were atopic. Prick-tests and PAST were positive for four and six patients (class 1), respectively. Food challenge on these six patients did not cause any migraine attacks. This study thus indicates a very low frequency of allergic dietary migraine to common foods.
