Natural History of Eosinophilic Esophagitis

Study Purpose

Researchers are trying to understand the course of Eosinophilic Esophagitis (EoE), its progression and effects of treatments.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT03290482
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Eosinophilic Esophagitis
Additional Details

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.

Arms & Interventions

Arms

: 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: Evaluation by the PI physical examination Complete the modified Mayo dysphagia Questionnaire (MDQ) and the Eosinophilic Esophagitis Activity Index (EEsAI) questionnaires Barium Esophagram with maximal and minimal esophageal diameter measurement EsophaCap cytology

Interventions

Diagnostic Test: - Barium Esophagram

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.

Device: - EsophaCap

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)

Diagnostic Test: - Physical Examination and Questionnaires

Complete the modified Mayo dysphagia Questionnaire (MDQ) and the Eosinophilic Esophagitis Activity Index (EEsAI) at time of physical exam visit with PI.
