Abstract

Abstract : The incidence of Eosinophilic Oesophagitis (EoE) is increasing worldwide in the paediatric population. Management of these children is complex, and includes elimination diet (2/4/6 food), steroids etc. It is recommended to perform endoscopies between each reintroduction to assess disease activity. In our centre dietary exclusion is the standard practice. Since 2019 we follow a step-up approach with regards to elimination diet starting with 2 food exclusion diet (FED) and building up as required. Food is reintroduced gradually with significant dietetic support and proactive monitoring including endoscopy. Objectives: We looked at the outcomes of children with EoE referred to Maidstone and Tunbridge Wells NHS Trust from Kent and East Sussex. Methods: Retrospective review of case notes of paediatric patients diagnosed with EoE between January 2015 and December 2020. Data collected included symptoms, endoscopy findings and histology at diagnosis and compared the same after dietary intervention. Results: 21 patients were diagnosed with EoE between January 2015 and December 2020 between 5–16 yrs Median age at diagnosis 11years. Frequently seen in boys (65%). Dysphagia was the predominant symptom (76%) followed by vomiting (60%), abdominal pain (50%), and choking (20%). Features of EoE were seen during endoscopy in 71% and oesophagus looked endoscopically normal in 29% of patients. Diagnosis was made on eosinophil count as per ESPGHAN guidance. The frequency and timing of repeat endoscopies following dietary intervention varied due to a multitude of factors including COVID-19 restrictions (between 4–9 months median 4 months). Histological remission (Eosinophils <15 pHPF) was achieved in 15/21 (70%) of patients. 7/10 children on 2FED, 3/3 patients on 4FED and 5/5 children on 6FED achieved histological resolution. The 6FED group took significantly longer to identify the causative food, establish long term dietary management and required more endoscopies. Food was reintroduced gradually on an individual basis with the aim of introducing back all food groups. 13/15 continue to be on milk free diet, 5/15 remain on milk and wheat free diet, 1/15 on soya and egg free diet and the other patient remains on 4FED (parental choice). 2 patients have started steroids due to on-going symptoms findings on surveillance endoscopy and histological following re-introduction. Summary and Conclusion: Dysphagia was the predominant symptom in our cohort of patients. Furrowing and oedema was the major finding during endoscopy. With dietary exclusion endoscopic resolution was seen in 62% and histological resolution seen in 70% of patients at first surveillance endoscopy. Re-introduction continues to remains a major challenge and we have not been able to introduce all the food groups in any of our patients due to either symptoms or recurrence on endoscopy/histology.
