Eosinophilic esophagitis (EoE) has been reported to be more prevalent in patients with esophageal atresia/tracheoesophageal fistula (EA-TEF). To date, there is limited data on the management of EoE in this group of patients. The aim of this study is to evaluate the treatment outcomes of EoE in children with EA-TEF. A retrospective chart review was performed on all EA-TEF children who were diagnosed with and treated for EoE between January 2000 and September 2013 at the Sydney Children's Hospital. Data collected included details of the patient's treatment, post-treatment endoscopy, symptoms and nutrition. Twenty patients were included in the study. Median age at diagnosis was 26 months (8-103 months), and median time from diagnosis to last follow-up was 23 months (2-132 months). Patients were treated with budesonide slurry, swallowed fluticasone, elimination diet alone or in combination. All patients were on proton pump inhibitors at time of diagnosis of EoE which was continued. Six out of seven patients who had furrowing/exudate in endoscopy at diagnosis had complete resolution at a median follow-up period of 26 months (P = 0.031). Median peak intraepithelial eosinophil count reduced significantly from 30/high-powered field (HPF) (19-80/HPF) to 8/HPF (0-85/HPF) (median time for improvement = 24 months) (P = 0.015). There was a significant reduction in symptoms of dysphagia and reflux post-treatment (P < 0.001). Prevalence of strictures significantly decreased (P = 0.016), as did need for dilatations (P = 0.004). In four out of six patients with gastrostomies at baseline, the feeding improved on treatment of EoE and the gastrostomy could be closed. There was also a nonsignificant trend towards improvement in weight and height 'z scores' of the patients. Treatment of EoE in children with EA-TEF was found to significantly reduce intraepithelial eosinophil count, symptoms, strictures and need for dilatations.
Background: A high prevalence of eosinophilic esophagitis (EoE) has been preliminarily reported in patients after repair of esophageal atresia (EA), but the basis of this association is unknown Objectives: We aimed to (1) characterize the EoE transcriptome in patients with EA, (2) compare the EoE transcriptome in patients with EoE and EA with that in patients with EoE alone, and (3) identify transcripts that could predispose patients with EA to EoE. Methods: This single-center, population-based, retrospective study identified 4 EoE study cohorts: healthy control subjects, patients with EA and EoE (EA+EoE+), patients with EA without EoE (EA+EoE-), and patients with EoE without EA (EA-EoE+). Molecular signatures were assessed by using the EoE diagnostic panel, a 94-gene expression quantitative PCR array. Results: In a cohort of 110 pediatric patients with surgically repaired EA, 20 (18%) patients were given a diagnosis of EoE, representing a 364-fold enrichment of EoE in patients with EA compared with the general pediatric population. EoE diagnostic panel analyses revealed a major overlap between the EA+EoE+ and EA-EoE+ cohorts. A proportion (approximately 25%) of EoE signature genes were dysregulated in patients with EA+EoE-compared with healthy control subjects, including those involved in epithelial barrier function and type 2-associated inflammatory responses. Patients with EA+EoE+ exhibit a more severe EoE clinical phenotype than those with EA-EoE+ in terms of dysphagia and dilation need. Conclusions: Patients with EA have increased risk of EoE. Patients with EoE with EA have a similar molecular profile compared with that of patients with EoE without EA.
Congenital tracheal stenosis is a rare but serious condition with high mortality and morbidity. We present a 6-month-old patient with complex congenital tracheal stenosis involving the trachea, carina and right bronchus intermedius, which was corrected with a combination of slide tracheoplasty and side-to-side bronchoplasty.
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.
