Clinical outcome and component-specific antibody levels in egg allergic children after lightened oral immunotherapy.
Objective: To evaluate the clinical outcome of lightened version of egg oral immunotherapy (OIT) and to analyze egg allergen component-specific antibody levels during short up-dosing with egg white powder and maintenance by egg in daily diet.
Patients and methods: Eighteen egg-allergic children received egg powder with short up--dosing and they maintained tolerance using egg in daily diet. Seventeen egg-allergic children served as a control group. Component-resolved analysis of serum immunoglobulin E (IgE), IgA1, IgA2, and IgG4 levels were determined at inclusion, after up-dosing and after 1 year of immunotherapy. Skin-prick tests were performed at inclusion and after 1 year of therapy.
Results: All 18 patients in the egg OIT group were successfully desensitized. Desensitization was achieved on average in 4.5 months. In the control group, only two children tolerated egg in oral food challenge after 1 year. Of the measured immune markers, smaller wheal diameters in skin-prick testing, reduction in component-specific IgE levels, and increase in component-specific IgA1, IgA2, and IgG4 levels were associated with desensitization.
Conclusion: A lightened egg OIT is effective and safe in children with egg allergy. Increase in all egg component-specific IgA1, IgA2 and IgG4 levels and decrease in all egg component--specific IgE levels were observed after 12 months of OIT.
期刊介绍：
Founded in 1972 by Professor A. Oehling, Allergologia et Immunopathologia is a forum for those working in the field of pediatric asthma, allergy and immunology. Manuscripts related to clinical, epidemiological and experimental allergy and immunopathology related to childhood will be considered for publication. Allergologia et Immunopathologia is the official journal of the Spanish Society of Pediatric Allergy and Clinical Immunology (SEICAP) and also of the Latin American Society of Immunodeficiencies (LASID). It has and independent international Editorial Committee which submits received papers for peer-reviewing by international experts. The journal accepts original and review articles from all over the world, together with consensus statements from the aforementioned societies. Occasionally, the opinion of an expert on a burning topic is published in the "Point of View" section. Letters to the Editor on previously published papers are welcomed. Allergologia et Immunopathologia publishes 6 issues per year and is included in the major databases such as Pubmed, Scopus, Web of Knowledge, etc.
