Eosinophilic esophagitis as a side-effect of allergen immunotherapy: protocol for a systematic review and meta-analysis

OpenAlex İngilizce

Background; Sensitization to food and airborne allergens is common in the majority of patients with eosinophilic esophagitis (EoE).Although there is not a direct cause-effect relationship of IgEmediated allergy with the pathogenesis of EoE, there is a growing evidence that oral desensitization to food and sublingual immunotherapy (SLIT) may induce the development of EoE as an adverse effect.As part of the 'EoE and Allergen Immunotherapy (AIT)' Task Force funded by the European Academy of Allergy and Clinical Immunology (EAACI), a systematic approach will be followed to review the evidence from the published scientific literature on the development of EoE in children and adults under any type of AIT.Methods; This systematic review will be carried out following the PRISMA statement guidelines.Studies will be assessed for inclusion in the review according to the Population-Interventions-Comparators-Outcomes (PICO) criteria. Results; Expected outcomes will provide evidence on the AIT-EoE development connection.Conclusion; The findings from this review will be used as a reference to provide useful guidelines for physicians treating patients with EoE and/or are practicing AIT.
