Introduction: Eosinophilic esophagitis (EoE) is one of the most prevalent esophageal diseases and the leading cause of dysphagia and food impaction in children and young adults. This underlines the importance of optimizing diagnosys and treatment of the condition, especially after the increasing amount of knowledge on EoE recently published. Therefore, the UEG, EAACI ESPGHAN, and EUREOS deemed it necessary to update the current guidelines regarding conceptual and epidemiological aspects, diagnosis, and treatment of EoE. Methods: General methodology according to the Appraisal of Guidelines for Research and Evaluation (AGREE) II and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was used in order to comply with current standards of evidence assessment in formulation of recommendations. An extensive literature search was conducted up to August 2015 and periodically updated. The working group consisted of gastroenterologists, allergists, pediatricians, otolaryngologists, pathologists, and epidemiologists. Systematic evidence-based reviews were performed based upon relevant clinical questions with respect to patient-important outcomes. Results: The guidelines include updated concept of EoE, evaluated information on disease epidemiology, risk factors, associated conditions, and natural history of EoE in children and adults. Diagnostic conditions and criteria, the yield of diagnostic and disease monitoring procedures, and evidence-based statements and recommendation on the utility of the several treatment options for patients EoE are provided. Recommendations on how to choose and implement treatment and long-term management are provided based on expert opinion and best clinical practice. Conclusion: Evidence-based recommendations for EoE diagnosis, treatment modalities, and patients' follow up are proposed in the guideline.
Eosinophilic esophagitis (EoE) is a chronic immune/antigen-mediated disease, with dysphagia as the main symptom. The aim of this study was to survey symptoms and health-related quality of life in adult patients with EoE at least 1 year after diagnosis and a 2-month course of topical corticosteroids. Forty-seven consecutive patients [79 % males, mean age 49 years (range 18-90 years)] were evaluated using three different questionnaires at three different occasions: the Watson Dysphagia Scale (WDS), the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Oesophageal Module 18 (EORTC QLQ-OES18) and the Short Form-36 (SF-36). The median time from diagnosis to the long-term follow-up was 23 months (range 12-34 months). The WDS scores and the EORTC QLQ-OES18 Dysphagia and Eating scale scores were improved after 2 months of treatment (p = 0.00007, p = 0.01, p = 0.004, respectively), as were the long-term follow-up scores (p = 0.01, p = 0.03, p = 0.005, respectively), relative to the scores at diagnosis. In addition, the EORTC QLQ-OES18 Choking scores were improved after the steroid course (p = 0.003) but not after the long-term follow-up. No significant differences were detected with respect to the SF-36 scores. In summary, EoE seems to be associated with a substantial burden of symptoms that improve significantly after treatment. A partial remission persists more than 1 year after diagnosis and the discontinuation of medication. The WDS and the EORTC QLQ-OES18 appear to be sensitive instruments appropriate for surveillance in these patients.
The dysphagia and impaired HRQL found in untreated patients with eosinophilic esophagitis improved significantly after 2 months of mometasone furoate treatment. A randomized placebo-controlled trial is warranted to assess causality. The scales and questionnaires used are sensitive instruments appropriate for symptom surveillance in individuals with eosinophilic esophagitis.
There was a significant seasonal variation in the incidence of acute esophageal bolus impaction. This variation was pronounced in patients with a coexisting atopic diathesis but was nonsignificant in patients without atopy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
