Diagnosis and management of eosinophilic esophagitis in children: An update from the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN).

INTRODUCTION: Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus characterized by symptoms of esophageal dysfunction and histologically by predominantly eosinophilic infiltration of the squamous epithelium. European Society for Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) published a guideline in 2014; however, the rapid evolution of knowledge about pathophysiology, diagnostic criteria, and therapeutic options have made an update necessary. METHODS: A consensus group of pediatric gastroenterologists from the ESPGHAN Working Group on Eosinophilic Gastrointestinal Diseases (ESPGHAN EGID WG) reviewed the recent literature and proposed statements and recommendations on 28 relevant questions about EoE. A comprehensive electronic literature search was performed in MEDLINE, EMBASE, and Cochrane databases from 2014 to 2022. The Grading of Recommendations Assessment, Development and Evaluation system was used to assess the quality of evidence and formulate recommendations. RESULTS: A total of 52 statements based on the available evidence and 44 consensus-based recommendations are available. A revision of the diagnostic protocol, options for initial drug treatment, and the new concept of simplified empiric elimination diets are now available. Biologics are becoming a part of the potential armamentarium for refractory EoE, and systemic steroids may be considered as the initial treatment for esophageal strictures before esophageal dilation. The importance and assessment of quality of life and a planned transition to adult medical care are new areas addressed in this guideline. CONCLUSION: Research in recent years has led to a better understanding of childhood EoE. This guideline incorporates the new findings and provides a practical guide for clinicians treating children diagnosed with EoE.

Differences in Management of Eosinophilic Esophagitis in Europe: An Assessment of Current Practice.

OBJECTIVES: The aim of the study was to assess differences in the diagnosis and management of eosinophilic esophagitis (EoE) by European pediatric (PG) and adult gastroenterologists (AG), and their self-reported adherence to guidelines. METHODS: A multiple-choice questionnaire gauged the diagnostic and management strategies of gastroenterologists treating children or adults in 14 European countries and the United Arab Emirates (UAE). RESULTS: Questionnaires were completed by 465 PG and 743 AG. PG were significantly more likely to take biopsies in patients with symptoms of esophageal dysfunction (86.2% PG vs 75.4% AG, P < 0.001) and to perform endoscopic follow-up (86.3% PG vs 80.6% AG, P < 0.001). After failure of proton-pump inhibitors (PPIs), topical steroids were the preferred second-line therapy; however, PG opted more frequently for elimination diets (47.5% PG vs 13.7% AG, P < 0.001). More PG than AG indicated having read recent guidelines (89.4% PG vs 58.2% AG, P < 0.001). Geographic differences in practice were reported, with respondents from the United Kingdom, Portugal, and Spain more often adhering to recommended biopsy protocols. Physicians in the UAE, France, Lithuania, and Poland tended to opt for steroid therapy or elimination diets as first-line therapy, in contrast to most other countries. CONCLUSIONS: Significant differences in general practice between PG and AG were demonstrated with notable divergence from consensus guidelines. International practice variations are also apparent. Among other strategies, educational activities to highlight current recommendations may help harmonize and optimize clinical practice.
