Analysis of allergic sieving detection results and clinical significance in children with allergic disease

Abstract

To explore the clinical use of sieving detection among the childhood with allergic disease. The sieving detection about allergen inhalant allergens, Fx5 in the CAP anaphylactogen detection system, and serum specific IgE were detected in three hundred and thirty-one cases of children (aged from 1 year to 14 years old) with allergic disease. Patients were divided into group 1, group 2 and group 3 according to the age from 0 to 3, 3 to 6, and 6 to 14 years old. All datas were statistical analysed among different age groups. Among the 331 patients, the positive rate of allergic sieving detection was 67.98%, the elevation rate of IgE was 53.78%. Inhalant allergen positive rate was 60.42%, while the food allergen positive rate was 28.10%. Inhalant allergen positive rate of the group 3 (aged from 6 to 14 years old) was significant higher than the other two age groups (68.45%). And the food allergen positive rate of the age group 1 (aged from 0 to 3 years old) was significant higher than the other two age groups (62.50%). Positive rate for simply inhalant allergen was 39.88%, while positive rate for simply food allergen was 7.55% and mixed allergen was 20.54%. Inhalant allergen was the main allergen of the children with allergic disease aged over 3 years old, while food allergen was the main allergen of the children with allergic disease aged below 3 years old. It was safe, sensible and effective to use Uni CAP anaphylactogen detection system for rapid assay of specific allergens.
