Introduction and Objectives: Although food allergy is recognized as a growing worldwide public health problem, there continues to be limited data on prevalence rates in developing and emerging countries. Most prevalence estimates are based on self-reports, with only few studies using objective assessments. The aim was to analyze the frequency of sensitization to food allergens by serum specific IgE in a large group of unselected allergic patients in Mexico., Materials and Methods: We analyzed data registries from patients of all ages with suspected food allergy referred to a specialized laboratory in Mexico City from January 2016 to April 2018. A descriptive analysis, and an age/food-group comparison were made., Results: A total of 2633 subjects tested for food allergy were identified during the study period; 1795 subjects fulfilled the inclusion criteria. The overall positivity (sIgE≥0.35kUA/L) to at least one food was 24%. The most frequently positive foods were hazelnut, apple, shrimp, peanut, egg white, egg yolk, peach, almond, tomato, bean, milk, strawberry, kiwi, maize and wheat. Positivity for some foods was more frequent across different age groups, in young children (≤5 years) milk; in older children (6-17 years): peanut, almond, wheat, soy and maize; in adults: apple. We also found other foods with high positivity but less than 50 samples: rye 60%, mango 42.9%, carrot 37.5%, cashew 27.3%, banana 21.1% and oat 20.6%., Conclusion: Our study reported the presence of a differential regional IgE sensitization pattern as compared with the internationally reported one, highlighting the importance of local staple foods., (Copyright © 2020 SEICAP.

The vast majority of patients with allergic rhinitis (AR) do not receive the proper management which is recommended by the guidelines, but they frequently self-medicate. MASK (Mobile Airways Sentinel Network) is an integral part of a project that is supported by the European Union against chronic diseases and focused on active and healthy aging. MASK represents the third phase of ARIA (Allergic Rhinitis and its Impact on Asthma), in which, by using a mobile application in a smart device, the objective is to guide the patient in the control of his/her multi-morbidity, AR and/or allergic conjunctivitis (AC) and/or asthma. The mobile app Allergy Diary by MACVIA-ARIA is free and it is available for both Android and iOS platforms. After it is downloaded to the patient's cell phone, it first requests some information about the patient's profile, allergic pathologies and medication; afterwards, through a visual analog scale, the patient is invited to determine the degree of affectation in the nose, eyes, and bronchi, and its influence on their productivity at work / school. After analyzing the data generated by filling the Allergy Diary, it became clear there is a new clinical entity: allergic rhinitis+ allergic conjunctivitis +asthma, with greater effect; in addition to a high level of self-medication: in general, the patient takes medication on days when symptoms are present. The app has already been deployed in 23 countries, including several Spanish-speaking countries.
