    Abstract:
    OBJECTIVE: To determine the frequency of sensitization to inhalant and food allergens in children seen at Brazilian allergy services. PATIENTS AND METHODS: Total and specific IgE serum levels to inhalant and food allergens (RAST, UniCAP - Pharmacia) were measured in 457 children accompanied in pediatric allergy services and in 62 control children age matched. RAST equal or higher than class 1 was considered as positive (R+). RESULTS: Frequency of R+ was significantly higher among atopics (361/457, 79%) when compared to controls (16/62, 25.8%). There were no differences according to gender. The frequency of R+ to all allergens evaluated was higher among atopics when compared to controls. Significantly higher total IgE serum levels were observed among the atopics with R+ in comparison to those with R-. The frequency of R+ to main inhalant allergens were: D. pteronyssinus = 66.7% x 14.5% (p < 0.05), D. farinae = 64.5% x 17.8% (p < 0.05), B. tropicalis = 55.2% x 19.4% (p < 0.05), cockroach = 32.8% x 9.7% (p < 0.05), and cat = 12% x 8.1%. In relation to food allergens we observed: fish = 29.5% x 11.3% (p < 0.05), egg = 24.4% x 4.8% (p < 0.05), cow's milk = 23.1% x 3.2% (p < 0.05), wheat = 20% x 8.1% (p < 0.05), peanuts = 14% x 4.8% (p < 0.05), soy = 11.8% x 4.8% (p < 0.05), and corn = 10.6% x 4.8% (p < 0.05). With respect of age, food allergen sensitization predominates in young children whereas the inverse occurs with inhalant allergens. CONCLUSIONS: There was a predominant frequency of sensitization to inhalant allergens, mainly house dust mites in the evaluated patients. Food allergens were also responsible for a significant proportion of sensitization, mainly in infants.
