Precision medicine in food allergy

Purpose of review To familiarize the reader with the concept of precision medicine in food allergy through the most recent insights in the diagnosis, prognosis, and management of the disease. Recent findings With the advent of omics sciences, a new era is commencing. Food protein allergens characterization and quantification together with the immunoglobulin E epitope mapping will contribute to the diagnosis/prognosis of food allergy and will lead to a better safety assessment of foods. The characterization of biomarkers able to identify specific phenotypes and endotypes will improve the diagnostic accuracy. This together with a better understanding of mechanisms of action of the different therapeutic options will allow the accurate selection of the appropriate patient. Summary In the near future, advances in technologies and data interpretation will allow a better understanding of the pathogenesis of food allergy and the development of a personalized treatment tailored on the specific patient' profile.
