Children with eosinophilic esophagitis in real life: 10 years' experience with a focus on allergic management

INTRODUCTION AND OBJECTIVES: Eosinophilic esophagitis (EoE) is frequently miss-diagnosed or overlooked for several years because of the invasiveness of investigations and the non-specificity of symptoms in childhood. Due to the lack of specific recommendations in children, its management remains very heterogeneous, especially concerning allergy testing. The aim of this study is to analyze our population and practices, in comparison with the literature, with a focus on allergic management, to harmonize and optimize our practice. MATERIAL AND METHODS: We included all children with a diagnosis of EoE at the Hospital Femme Mere Enfant, Bron, France. Data were collected via retrospective chart review. RESULTS: 108 patients were included with an average age of 9.5 years. Average delay before diagnosis was 6.65 years. Symptoms varied with age, with a predominance of vomiting (60% of patients), feeding difficulties (72%) and growth difficulties (24%) in children \textless5 years, whereas older children often presented with feeding blockage (64%) and dysphagia (61%). Cough was frequent in our cohort (18.5%), especially in children \textless10 years (38.5% between three and five years). The allergic background was frequent (70.3%) and 80% of our patients benefited from allergy testing. Allergy testing was particularly useful to guide therapy as elimination diet represented an effective treatment in 60% of our patients CONCLUSIONS: Allergy testing has to be harmonized to include major allergens (egg, milk, peanut, fish, wheat, and soy), including prick and patch tests. Allergy-testing based diet seemed to be the best compromise between efficiency and constraints, especially in mono-sensitized patients

Oral food challenge in children: an expert review

Oral food challenges are indicated for the diagnosis of food allergy and the double-blind, placebo-controlled oral food challenge is considered the gold standard diagnostic method in children with suspected food allergy. This practice parameter for oral food challenges in children was prepared by a workgroup at the request of the French Society for Allergology and Clinical Immunology (SFAIC) and the French Paediatric Society for Allergology and Pulmonology (SP2A). We aimed to develop practical guidelines for oral food challenges in children for the diagnosis of suspected food allergy or the evaluation of food tolerance. We also considered the safety measures to be implemented during testing and management of the potentially serious allergic reactions that may arise during the test. The strength of the recommendations was established, using the GRADE evidence-based approach. We considered four issues: (1) the selection of children for oral food challenges (indications and contraindications); (2) the procedure used (material, where the test should be carried out, technique and management of reactions); (3) interpretation of the test and (4) consequences of the test
