[Investigation of allergens in 3,504 children with allergic diseases].

ABSTRACT

OBJECTIVE: To investigate the allergens of various allergic diseases in children. METHODS: Serum levels of Fx5E, Phadiatop and specific IgE were measured by the UniCAP100 System in 3 504 children with allergic diseases. RESULTS: The positive rate of aeroallergens was obviously higher than that of food allergens in children with allergic rhinitis, allergic conjunctivitis, asthma and papular urticaria. In contrast, the positive rate of food allergens was obviously higher than that of aeroallergens in children with Henoch-Schonlein purpura and digestive diseases. The serum specific IgE level of aeroallergens was higher than that of food allergens. The dust and mite specific IgE levels reached to grade 6, while the food allergen specific IgE levels were lower than grade 3. CONCLUSIONS: Aaeroallergens or food allergens vary remarkably in different allergic diseases in children. The level of specific IgE of aeroallergens is higher than that of food allergens.
