Cytosponge and Dietary Therapy in EoE
This study is being done to see if the investigators can use only the cytosponge ( A 10 minute, in office procedure that does not require sedation) to replace the 6-10 endoscopies routinely perform during dietary restriction and food reintroduction in EoE?
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
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.
|Eligible Ages||18 Years - 70 Years|
Inclusion Criteria:- Diagnosed with Eosinophilic Esophagitis > than 15 Eos phf and failed to respond to the PPI therapy - Going through the six food elimination diet or have just completed elimination the six foods: fish, nuts, eggs, soy, wheat, and milk
Exclusion Criteria:- Clinical evidence of infectious process potentially contributing to dysphagia ( candidiasis, CMV, herpes) - Other cause of dysphagia identified at endoscopy (e.g. reflux esophagitis, stricture, web, ring, achalasia, esophageal neoplasm) - Esophageal minimal diameter < 13 mm on structured barium esophagram
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.
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.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.
The person who is responsible for the scientific and technical direction of the entire clinical study.

Dietary Therapy has been shown to be successful in the treatment of adult and pediatric patients with eosinophilic esophagitis Dietary studies were initially reported in children, but the results appear to be similar in adult patients. Elemental diets are successful in 70-95% of patients but are poorly tolerated. A six food elimination diet has been effective in about 70% of adult patients with EoE . In these adult studies skin prick testing was not helpful in predicting which foods would lead to a flare of disease when reintroduced into the diet. Therefore, the current standard of care requires multiple EGDs with esophageal biopsy during the dietary restriction and reintroduction phases of this study. Since the investigators are making lifelong dietary decisions during this process of food reintroduction, it is imperative the investigators be accurate. Unfortunately, these multiple EGDs have significant cost and are invasive procedures with some risk. Moreover, there is significant indirect costs with travel and time off work for the patients and drivers. Previous studies have found the esophageal sponge to be an accurate technique of accessing esophageal eosinophilia in EoE . The sponge is swallowed as a 12 mm capsule on a string. The capsule rapidly dissolves upon entering the stomach and the sponge then expands and can be pulled out the mouth five minutes after ingestion. In previous studies, the procedure was very well tolerated and all patients preferred the sponge to endoscopy. Therefore the sponge is a well tolerated, inexpensive, very low risk procedure that would be an ideal option to replace EGD esophageal sampling in the evaluation of dietary treatment of EoE.
