Non-endoscopic Tracking of Disease Activity in Eosinophilic Esophagitis

Eosinophilic Esophagitis Clinical Trial

Official title: Non-endoscopic Tracking of Disease Activity During Dietary Interventions in Eosinophilic Esophagitis

Status Withdrawn

Clinical Trial Summary

To prospectively determine the natural history of inflammation resolution following initiation of diet treatment and to optimize the diet treatment of patients with EoE through the use of a non-endoscopic tracking device, the esophageal string test (EST).

Clinical Trial Description

This is an adult and pediatric prospective, longitudinal study in which we will measure symptoms, QOL and inflammation at baseline and again at 2, 4 and 6 weeks after starting stand of care (SOC) four food elimination diet (FFED) (Aim 1). Newly or previously diagnosed patients with EoE with active disease who will be undergoing SOC FFED will be offered entry into the study by the PI's or their local co-investigators at each of their institutions. EoE patients who are in remission on SOC FFED from Aim 1 will be recruited to participate in this food reintroduction trial in Aim 2. Eligible subjects will undergo SOC sequential food reintroductions and during the food introduction, ESTs will be performed at 2 and 4 week intervals during a clinic visit. If inflammation is detected by the EST, this food will be eliminated from the diet for six weeks and a repeat EST will be administered at this time to assess inflammation. If inflammation has resolved based on EST results, food reintroduction will resume. If no inflammation is detected by the EST at the 4 week interval, a new food will be added. EST will be performed after each food reintroduction as outlined above. Based on known allergenic properties of these foods, the order of food reintroduction will be soy, eggs, wheat and milk. ;
