What this trial studies

This is a prospective, observational registry enrolling adults (over 18) diagnosed with eosinophilic esophagitis and referred to the Motility and EoE Unit at IRCCS San Raffaele in Milan. Participants provide informed consent and their standard-of-care clinical, endoscopic, histologic, and related data are recorded longitudinally. No experimental treatments are administered as part of the registry; patients continue usual clinical care. The collected data will be used to describe disease features, support future retrospective or prospective studies, and foster national and international collaborations.

Who should consider this trial

Good fit: Adults (age >18) with a guideline-based diagnosis of eosinophilic esophagitis who are referred to the Motility and EoE Unit at San Raffaele and can give informed consent are ideal candidates.

Not a fit: People without a clear EoE diagnosis, those under 18, or those unwilling to provide informed consent will not be included and are unlikely to benefit from this registry.

Why it matters

Potential benefit: If successful, the registry could improve understanding of disease patterns and treatment outcomes and help design better-targeted research and care pathways for EoE patients.

How similar studies have performed: Prospective registries in EoE and other gastrointestinal diseases have been used successfully to define phenotypes, outcomes, and research priorities, so this approach is established rather than novel.
