The current treatment is the exclusion diet, which frequently affects the quality of life for these patients. The objective of the study was to describe the effect of omalizumab treatment in children diagnosed with MFAs who experienced frequent anaphylactic reactions and the impact on their quality of life. A descriptive observational study. Patients with severe food restrictions and high-risk due to multiple episodes of anaphylaxis were included. The allergy was confirmed by compatible clinical, skin tests, positive specific IgE and oral food challenges (OFCs). Omalizumab treatment was initiated and the impact on the life quality of patients and their families was assessed using the validated Food Allergy Quality of Life Questionnaire-Parent Form. Five patients with an average age at diagnosis of 3.58 years (range between 1.5-7.9 years), were diagnosed with MFAs. All patients presented with anaphylaxis. All patients wetly, these patients were able to significantly expand the variety of their diet, improving the life quality and avoid anaphylaxis following the inadvertent intake of these foods. It was urgent to explain the role of egg yolk allergen sensitization to the egg allergic population and we would evaluate the diagnostic value of allergen components in whole eggs, including egg white and egg yolk. Firstly, we collected 99 positive and 21 negative sera against egg allergy. Then we used modified enzyme linked immunosorbent assay (ELISA) to survey specific IgE (sIgE) to all-proven and single component in eggs, Ovomucoid (Gal d 1), Ovalbumin (Gal d 2), Ovotransferrin (Gal d 3), Lysozyme C (Gal d 4), Serum Albumin (Gal d 5), and YGP42(Gal d 6) in allergic and non-allergic populations. Last but not least, we studied the sIgE reactivities to egg allergen components by receiver operating characteristic (ROC) analysis. Among egg-aller
