The prevalence of IgE-dependent food allergy in asthmatic children

Results Based on a survey showed that 180/362 (49.7%) children with asthma had symptoms that were associated with the consumption of food. Sensitization to food allergens was found in 70 (19.3%) children with asthma. Oral provocation tests using DBPCFC was performed in 50 children with asthma, in whom the results of the interview and / or SPT and / or specific IgE indicated a possible involvement of food allergens on symptoms of IgEmediated reactions. The positive results of oral food tests was found in 20 (5.5%) children with asthma. After including 4 children with a well-documented history of anaphylactic reactions, IgE-mediated food allergy was diagnosed in 24 patients with asthma (6.6%). Respiratory symptoms as a result of oral food challenges occurred in 3% of children with asthma, however the asthmatic symptoms related to 9/362 (2.5%) of the children. Conclusion IgE-dependent food allergy was diagnosed in 6.6% of children with asthma. Respiratory symptoms as a result of food allergen provocation occurred in 3% of children with asthma.
