Insights
Eosinophilic esophagitis (EoE) in children presents with varied symptoms, often mimicking reflux. Diagnosis requires esophageal biopsy, and treatments like swallowed fluticasone or diet restriction show symptom improvement.
Area of Science:
- Gastroenterology
- Pediatric Medicine
- Allergy Immunology
Context:
- Eosinophilic esophagitis (EoE) is an emerging esophageal inflammatory condition.
- EoE shares symptoms with gastroesophageal reflux disease, complicating diagnosis in children.
- Understanding EoE's pediatric presentation is crucial for timely diagnosis and management.
Purpose:
- To detail the clinical features, diagnostic methods, treatments, and outcomes of 29 pediatric eosinophilic esophagitis cases.
- To characterize symptom presentation across different age groups in children with EoE.
- To evaluate treatment efficacy and histological response in children with EoE.
Summary:
- Twenty-nine children (22 boys) diagnosed with eosinophilic esophagitis (EoE) were analyzed.
- Common symptoms included vomiting and abdominal pain; age-specific presentations varied.
- Endoscopic findings ranged from normal to furrowing and papules; treatment with fluticasone or diet led to symptom remission and reduced eosinophil counts.
Impact:
- Highlights the importance of considering EoE in children with refractory reflux-like symptoms.
- Emphasizes the necessity of esophageal biopsies for accurate EoE diagnosis.
- Demonstrates the effectiveness of swallowed fluticasone and dietary modifications in managing pediatric EoE.
Background:
Eosinophilic esophagitis is a recently described entity with esophageal symptoms like gastroesophageal reflux disease and significant esophageal eosinophilic infiltration.
Aim:
To present our clinical series of 29 children with eosinophilic esophagitis, describing the clinical and diagnostic features, treatment and outcome.
Methods:
We describe 29 patients (22 boys), 1-18 years-old, with 20 eosinophils per high-power field in esophageal biopsy specimens and absence of eosinophilic inflammation in the stomach and duodenum. Evaluation of the clinical, endoscopic and histologic findings, treatment and outcome was undertaken.
Results:
The most common presenting symptoms included vomiting in 15 patients (52%) and abdominal pain in 11 patients (38%). Children under the age of 4 years presented with feeding disorder and failure to thrive. Patients between 5 and 8 years of age presented commonly with abdominal pain or symptoms that may be associated with reflux (heartburn and/or vomiting). Patients over the age of 8 presented most often with abdominal pain, dysphagia and occasional food impaction. Endoscopic features included vertical furrowing in 14 patients (48%), whitish papules in 12 (41%), corrugated rings in 2 patients (7%) and esophageal erosions in 3 patients (10%). In seven patients endoscopy was normal (24%). Treatment included swallowed fluticasone propionate in 19 patients and restriction diet in 7 patients. Patients who returned for follow-up had either improvement or remission of symptoms. After treatment, endoscopic biopsies were repeated in 11 patients, and a significant decrease in esophageal eosinophil counts was observed.
Conclusions:
The diagnosis of eosinophilic esophagitis must be considered when symptoms of reflux do not respond to conventional treatment. Upper gastrointestinal endoscopy must be complemented by a detailed analysis of histologic findings and eosinophil counts.
