Eosinophilic esophagitis (EoE) in children under six often presents with feeding issues and poor weight gain. Combination therapy showed higher remission rates in younger children with EoE.
Area of Science:
- Pediatric Gastroenterology
- Immunology
- Allergy
Background:
- Eosinophilic esophagitis (EoE) is a chronic immune-mediated esophageal disease.
- Diagnosis is common in school-aged children (6-9 years), but data on younger children is limited.
Purpose of the Study:
- To compare clinical presentation, comorbidities, and treatment outcomes of EoE based on age at diagnosis in children.
- To identify age-specific patterns in EoE presentation and response to therapy.
Main Methods:
- Retrospective chart review of 256 children (<18 years) diagnosed with EoE between 2005-2020.
- Patients were categorized into three age groups: <2 years, 2-<6 years, and 6-<18 years.
- Clinical data, family history, comorbidities, treatment, and endoscopic findings were analyzed.
Main Results:
- Vomiting was common in children <2 years; poor weight gain was more prevalent in the 2-<6 years group.
- Older children (6-18 years) were more likely to present with food impaction and abdominal pain.
- Combination therapy achieved higher remission rates (85%) in children <6 years compared to older children (66%).
Conclusions:
- EoE should be suspected in young children with feeding difficulties and poor weight gain.
- Combination therapy may be more effective for younger children with EoE.
- Further research with larger cohorts is needed to optimize combination therapy strategies for pediatric EoE.
