Pediatric Eosinophilic Esophagitis (pedEoE): Effect of Allergen Heat Denaturation on EoE Remission: a Pilot Trial
Universitaire Ziekenhuizen KU Leuven
36 participants
Dec 19, 2023
INTERVENTIONAL
Conditions
Summary
The objective of the study is to study whether the introduction of heated food products (more specifically heated hen's egg and/or cow's milk) in children with EoE would be possible without re-occurrence of the eosinophilic inflammation, while the intake of less heated products might cause disease recidive. Moreover, we would like to study whether the gradual re-introduction of less heated products after the most heated form is tolerated, could lead to tolerance induction in EoE.
Eligibility
Inclusion Criteria1
- All children (aged 12 months and older) presenting (since 1-1-2014: moment of diagnostic guideline standardization for pedEoE) with diagnosed pedEoE at UZ Leuven eliminating either hen's egg or cow's milk or both and in complete remission after their latest biopsy (no longer than 12 months earlier, but preferentially as short as possible after their latest biopsy) are eligible for the study. If the last biopsy has been performed more than 12 months earlier, a new gastro-duodenoscopy will be performed to verify remission and rule out e.g. active gastritis. If they are on PPI and/or local budesonide treatment, this should be stable for at least 3 months and will remain untouched during the entire study. We will include 18 pedEoE subjects suffering from cow's milk induced EoE and 18 suffering from hen's egg induced EoE.
Exclusion Criteria4
- Children younger than 12 months
- Children with active pedEoE
- Children who refuse to adhere to the protocol
- Children with associated IgE mediated hen's egg and/or cow's milk allergy with specific IgE antibody titers that predict active (baked egg and/or baked milk) food allergy with cut-off titers as used at the consultation of allergy (KLL). Those children will become eligible however if their titers decrease while the study is still open.
