Definition of Eosinophilic esophagitis
Eosinophilic Esophagitis (EoE) represents a chronic,
immune/antigen-mediated esophageal disease
characterized clinically by symptoms related to
esophageal dysfunction and histologically by
eosinophil-predominant inflammation

in patients with atopic diseases such as food allergy, asthma and allergic rhinitis

PPI-REE and EoE
– PPI-REE and EoE have similarities (phenotypic, genetic, pathogenetic mechanisms, clinical features)
– Katzka D.A., Clin Gastroenterol Hepatol 2014
– Transcriptome analysis revealed recently a similar pattern of gene upregulation and downregulation in EoE and PPI-REE patients, but not in GERD patients
– Wen T. et al., J Allergy Clin Immunol 2015
PPI-REE is NOT a separate entity but an EoE
sub phenotype
that responds clinically and histologically to PPIs

Stat 1
In patients with EoE, allergy tests such as
serum specific IgE, skin prick tests and
microarrays as well as atopy patch - alone
or in combination – are unable to reliably
identify causative foods.
Rec 1
ESPGHAN EGID WG recommends against the use of available allergy tests for identifying food triggers of EoE. Triggering foods should be identified by an elimination diet and consequent food reintroduction with histological assessment of esophagus.

ESPGHAN 2014 Recommendations on the use of esophageal dilatation
• Esophageal dilatation is only recommended in highly selected cases with severe esophageal
narrowing that persists despite other forms of treatment
• In all cases, esophageal dilatation must be accompanied by medical treatment of EoE

Rec 9c
ESPGHAN EGID WG recommends the use of either hydrostatic balloons or Savary-Guiliard
bougies for esophageal dilation as both are safe and effective. Choice of technique should be
based on the experience of treating physician.
Rec 9d
ESPGHAN EGID WG recommends to consider the use of systemic steroids in the presence
of esophageal stenosis with severe symptoms as an alternative to dilation (expert opinion).

Medical Position Paper of the ESPGHAN Gastroenterology Committee
and the EoE WG
Conclusions
• EoE is a chronic, relapsing inflammatory disease of the esophagus with largely unquantified long
term consequences
• Investigations and treatment are tailored to the individual and must not create more morbidity for
the patient and family than the disease itself
• Better maintenance treatment and novel therapies for long-lasting, treatment resistant disease,
as well as biomarkers for assessing treatment response and predicting long-term complications,
are urgently needed
