European guidelines update diagnostic criteria for eosinophilic esophagitis
A 32-expert panel developed evidence-based European guidelines on eosinophilic esophagitis (EoE) in children and adults, updating recommendations from 2017. The diagnosis requires symptoms of esophageal dysfunction and at least 15 eosinophils per high-power field; the guidance recommends at least six esophageal biopsies from two or more levels.
- Diagnosis combines symptoms with esophageal tissue eosinophilia.
- Obtain at least six biopsies from two esophageal levels.
- Endoscopic appearance alone is insufficient for diagnosis.
- Gastric and duodenal biopsies are not routinely required.
A 32-expert panel representing EUREOS, EAACI, ESPGHAN and ESP developed updated European guidelines on eosinophilic esophagitis (EoE). The panel searched the literature using a PICO framework, assessed evidence with GRADE and reached consensus through a Delphi process requiring at least 80% agreement. Part 1 addresses definition, epidemiology, natural history and diagnosis in children and adults.
The guidelines report an annual incidence exceeding 10 cases per 100,000 and pooled prevalence above 60 per 100,000, with prevalence exceeding 160 per 100,000 in some regions. EoE diagnosis requires symptoms of esophageal dysfunction and at least 15 eosinophils per high-power field in esophageal mucosa, after excluding other causes. The document distinguishes EoE from asymptomatic esophageal eosinophilia.
For diagnosis, the panel recommends obtaining at least six biopsies from at least two esophageal levels because endoscopic appearance alone is not sufficiently sensitive. Gastric or duodenal biopsies are not routinely required, but may be indicated by specific symptoms or endoscopic abnormalities. These are evidence-based consensus guidelines; the supplied abstract does not provide recommendation-specific certainty ratings or the full evidence details.
In practice
For children and adults assessed for eosinophilic esophagitis, the guideline defines diagnosis as symptoms of esophageal dysfunction plus at least 15 eosinophils per high-power field in esophageal mucosa, after excluding alternative causes. It recommends at least six esophageal biopsies from two or more levels because endoscopic appearance alone is insufficiently sensitive. Routine gastric or duodenal biopsies are not required unless symptoms or endoscopic abnormalities warrant them. These are consensus recommendations; the supplied abstract does not detail certainty ratings for each recommendation.
