About this study
Official title: Natural History of Eosinophilic Esophagitis: A Longitudinal Follow-up Over 10 Years
Researchers are trying to understand the course of Eosinophilic Esophagitis (EoE), its progression and effects of treatments.
Read the detailed description
Investigators will identify patients from their database who have been diagnosed with Eosinophilic Esophagitis (EE) from the study period 2000 to 2008, based on clinical features and biopsy findings. Participants will be offered a follow up evaluation that includes: evaluation by the Principal Investigator, completion of questionnaires, Esophagram and Esophageal sponge (EsophaCap) cytology.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Barium EsophagramDiagnostic test
Fast for 4 hours prior to the Esophagram (upper GI x-ray). You will drink a liquid that has barium or another contrast agent in it. The radiologist will use the X-ray machine to look at your upper GI tract while you drink the contrast liquid. The x-ray exam should take between 10-15 minutes.
EsophaCapDevice
Also called Sponge
Subjects will swallow the EsophaCap, which has a string attached, 10 minutes later it has devolved in the stomach. The PI will pull the string to remove the EsophaCap. We will send the sponge for cytology assessing the histologic results of eosinophils per high power field (phf)
Physical Examination and QuestionnairesDiagnostic test
Complete the modified Mayo dysphagia Questionnaire (MDQ) and the Eosinophilic Esophagitis Activity Index (EEsAI) at time of physical exam visit with PI.
| Study group | Role | What they receive |
|---|---|---|
| EE Study Patients 2000-2008 | All patients with the diagnosis of EE from the study period 2000 to 2008. Sixty patients participated in the 10 year follow up phone interview and questionnaire. These are the subjects we will contact to see if they are interested in participating in this study.
If interested in participating, subjects will complete:
1. Evaluation by the PI physical examination
2. Complete the modified Mayo dysphagia Questionnaire (MDQ) and the Eosinophilic Esophagitis Activity Index (EEsAI) questionnaires
3. Barium Esophagram with maximal and minimal esophageal diameter measurement
4. EsophaCap cytology Receives: Diagnostic Test: Barium Esophagram; Device: EsophaCap; Diagnostic Test: Physical Examination and Questionnaires |
What is being measured
The primary outcome is the main question the study is designed to answer.
Natural history of treated Eosinophilic Esophagitis (EE)
The number of recurrent symptoms using the modified Mayo Dysphagia Questionnaire (MDQ). The MDQ is a 32 - item instrument in which symptoms are divided into three symptom domains.
Measured: approximately 1 year
Natural history of untreated Eosinophilic Esophagitis (EE)
The number of recurrent symptoms using the modified Mayo Dysphagia Questionnaire (MDQ). The MDQ is a 32 - item instrument in which symptoms are divided into three symptom domains.
Measured: approximately 1 year
Natural history of treated Eosinophilic Esophagitis (EoE)
The number of recurrent symptoms using the Eosinophilic Esophagitis Activity Index (EEsAI). The EEsAI provides a visual analogue of foods for subjects to examine and rate for difficulty in swallowing ranging from severe difficulties to No difficulties.
Measured: approximately 1 year
Natural history of untreated Eosinophilic Esophagitis (EoE)
The number of recurrent symptoms using the Eosinophilic Esophagitis Activity Index (EEsAI). The EEsAI provides a visual analogue of foods for subjects to examine and rate for difficulty in swallowing ranging from severe difficulties to No difficulties.
Measured: approximately 1 year

Questions about this trial
What is this clinical trial studying?
An observational study of Eosinophilic Esophagitis, run by Mayo Clinic at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Natural history of treated Eosinophilic Esophagitis (EE) (time frame: approximately 1 year). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03290482, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Aug 2021; AzTrials last refreshed its copy on 7 Nov 2026.
