Use of component-resolved diagnosis in the follow-up of children with plant food allergy

Food allergy poses a major problem during childhood. Component-resolved diagnosis detects allergy to proteins isolated in food. This descriptive study analyzes the use of customized and standardized recommendations in a sample made up of 22 children aged 2 to 16 years old with plant food allergy and assesses sensitivity to four plant panallergens. According to component-resolved diagnosis results, therapy was personalized, guidelines on what foods or components to avoid were provided, and co-factors that may favor food allergic reactions were explained. No new reactions were referred by 20/22 cases. Oral allergy syndrome developed in 2/22 patients with allergy to profilin because they did not follow the recommendations. Component-resolved diagnosis was useful for the diagnosis and management of these children. Standardized recommendations, based on each patient's component-resolved diagnosis, prevented severe food allergic reactions.
