Atopic dermatitis is associated with food allergies. The aim of this study is to evaluate soy allergy in patients suffering from atopic dermatitis. Altogether 228 persons were included; specific IgE, skin prick tests, atopy patch tests, challenge tests with soy and history of soy allergy were evaluated. Soy allergy was confirmed in eight patients (3.5%, in four patients with worsening of atopic dermatitis, in four patients with oral allergy syndrome), sensitisation to soy was found in another 47 patients (20%) with no clinical manifestation after soy ingestion. Dependence was confirmed statistically between soy allergy and pollen allergy and soy sensitivity and pollen allergy. About 20% of patients suffering from atopic dermatitis are sensitised to soy. Clinical symptoms of soy allergy occur only in 3.5% of patients suffering from atopic dermatitis. [ABSTRACT FROM AUTHOR]

Few large studies concerning the importance of food allergy in adolescents and adult patients with atopic dermatitis exist. The evaluation of food allergy to egg white and yolk, peanuts, soy, cow milk and wheat in patients suffering from atopic dermatitis. Two hundred forty patients (70 men, 170 women) were examined. Complete dermatological and allergological examination was performed in all patients, including specific IgE, skin prick test and atopy patch test. The challenge test was performed according to the results of examinations with suspected foods. The food allergy to peanuts was confirmed in 20% of patients, to egg in 6%, to soy in 3.3%, to wheat in 2.5% and to milk in 0.8% – altogether in 65 patients (27.5%). The positive results in examinations without clinical symptoms of food allergy were recorded in another 78 patients (32.5%). The diagnostic work-up should comprise not only the laboratory methods, but also the diagnostic hypoallergenic diet and the challenge test. [ABSTRACT FROM AUTHOR]

Aim. The evaluation of the occurrence of peanut allergy in adolescent and adult patients suffering from atopic dermatitis. Methods. Altogether 175 persons suffering from atopic dermatitis were included in the study. A diagnostic work-up for food allergy to peanuts was performed (specific IgE, skin prick tests, atopy patch tests, history), and the patients were also examined for pollen allergy containing Bet v 1 and Bet v 2 allergens. Results. Allergic reactions to peanuts were recorded in 23% of patients, and another 16% of patients were sensitised to peanuts. A dependency between the occurrence of pollen allergy with Bet v 1 and Bet v 2 allergens and the results of the examination for peanut allergy is confirmed in our study. Conclusion. One-fifth of patients with atopic dermatitis suffer from peanut allergy; the most common symptom is oral allergy syndrome. [ABSTRACT FROM PUBLISHER]
