RecruitingPrevalence and Description of FIRE (Food Induced Immediate Response of the Esophagus) in the Pediatric Population With Eosinophilic EsophagitisA new clinical entity of eosinophilic esophagitis, Food Induced Immediate Response of the Esophagus or FIRE, has been described since 2020. Diagnostic criteria are not clearly established. Specific questioning is necessary for differential diagnosis, such as the oro-pharyngeal syndrome notably described in pollinics, or a mechanical blockage strictly speaking linked to esophagitis. The aim is to obtain epidemiological data on this entity.
