This systematic review and meta\u2010analysis aimed to study the incidence of confirmed EoE, developing as a side effect of AIT to food or airborne allergens, following the Preferred Reporting Items for Systematic Reviews and Meta\u2010Analysis (PRISMA) 2020 guidelines. The literature search was performed in three databases (PubMed, Embase and Scopus). Databases were searched from inception to March 31st, 2023. A total of 17 studies met the criteria for inclusion in the review. Fifteen studies, comprising 3,302 patients, were on food desensitization, and the overall estimate of EoE incidence, combining the results of these individual studies, was 2.31% (95% CI 1.45, 3.36). Registered data reported\n                    <jats:italic>de novo<\/jats:italic>\n                    cases of eosinophilic esophagitis, and its diagnosis was usually made during the maintenance phase of food desensitization. With the adopted searching strategy, only two studies on sublingual immunotherapy with aeroallergens meeting the inclusion criteria were retrieved, comprising 1,436 patients and not reporting cases of EoE. The meta\u2010analysis showed that the development of EoE is a common adverse effect of oral immunotherapy with food allergens, whereas it is uncommon during sublingual immunotherapy with aeroallergens.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Trial Registration:<\/jats:bold>\n                    PROSPERO: CRD42023425917\n
