The DiNAM-EoE-C Study: Esophageal Distensibility and Novel Assessment of Motility in Eosinophilic Esophagitis

Condition(s) studied

Study summary

Eosinophilic esophagitis is a chronic immune-mediated disease that may progress to fibrostenotic remodeling, leading to symptoms such as dysphagia, chest pain, and food impaction. Although current therapies aim to achieve inflammatory control and prevent fibrosis, some patients remain symptomatic despite endoscopic and histologic remission. In this subgroup, symptoms may reflect reduced esophageal distensibility, motility abnormalities, or altered symptom perception related to hypervigilance. This study aims to evaluate symptomatic EoE patients in histologic remission by assessing esophageal distensibility with FLIP before and after endoscopic dilation, investigating motility abnormalities with HRM, and exploring the role of hypervigilance in clinical outcomes.

Eligibility

  Change in esophageal distensibility plateau (mm) measured by functional lumen imaging probe (FLIP) from baseline to 8-12 weeks post dilation
• Change in esophageal body compliance measured by functional lumen imaging probe (FLIP) — 8-12 weeks
  Change in esophageal body compliance (mm²/mmHg), measured by functional lumen imaging probe (FLIP) from baseline to 8-12 weeks post dilation
