title: [The national survey of immediate type of food allergy].
abstract: There are not so many epidemiological data for food allergy in Japan due to lack of relevant investigation. Therefore we are to study the reality of the immediately type of food allergy by utilizing IgE and CAP-RAST data investigated in 1998 and 1999 by the Research Group of Public Welfare Ministry of Labor. The survey was conducted in cooperation with 2689 domestic hospitals which have pediatrics and more than 100 beds. We focused on patients who had the symptoms of allergy within 60 minutes after the intake of any offending food. The questionnaire was returned by 498 hospitals (collect rate 60.4%), which reported 1420 cases. We did not find clear relation between serum IgE and frequency of food allergy symptom and admission rate. On the other hand, we recognized that CAP-RAST had significant differences in the frequency of shock disease caused by the intake of milk products whereas there were no differences in any other major antigens. We concluded that both serum IgE value and CAP-RAST Class cannot indicate the severity of the immediate type of food allergy.
