• Study Type: interventional

Brief Summary

This is a single-center, prospective, pilot clinical trial in which children ages 3-17 years with eosinophilic esophagitis (EoE) who have a known food that triggers EoE flares receive oral desensitization with that specific food antigen, followed by reintroduction of that food into the diet. The purpose of this study is to investigate the safety and feasibility of oral desensitization in children with EoE so that, if determined to be safe, can be repeated on a larger scale to determine efficacy.

Conditions

Eosinophilic Esophagitis

Keywords

oral food desensitization; food elimination; food reintroduction

Outcome Measures

Primary Outcomes (1)

• Peak eosinophil count on esophageal biopsy

  Remission of esophageal eosinophilia as defined by having \<15 eosinophils per high power field on peak esophageal biopsy

  5 months

Study Arms (1)

Oral food desensitization

EXPERIMENTAL

All of the children enrolled in the study will receive oral food desensitization with his or her specific EoE flare-inducing food antigen (e.g. cow's milk protein). The food antigen will be diluted in a 50% glycerin/water solution containing ascorbic acid (Vitamin C) to stabilize and preserve the solution. This oral spray will need to be administered twice a day, every day for a total of 4 months.

Other: Oral food desensitization

Eligibility Criteria

• Age: 3 Years - 17 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17)

You may qualify if:

• Pediatric patient, ages 3-17 years, with known diagnosis of EoE based upon esophageal biopsy demonstrating ≥15 eos/hpf and lack of symptomatic or histological response to PPI therapy and/or normal esophageal pH evaluation.
• Known or suspected flare-inducing food trigger based upon supporting histological evidence.
• Already undergoing a baseline EGD followed by food reintroduction and repeat EGD, as standard of care at the recommendation of the child's gastroenterologist.
• Signed informed consent for the subject's participation in the study provided by the parent/ legal guardian and child/adolescent assent for subjects 7-17 years.
• Assent by the patient's pediatric gastroenterologist for the patient's participation in the study.

You may not qualify if:

• Presence of other disorders associated with similar clinical, histological or endoscopic features, such as PPI-responsive esophageal eosinophilia, esophageal eosinophilia associated with gastroesophageal reflux disease (GERD), Crohn's disease, infectious esophagitis (i.e. herpes simplex virus or candida), drug-associated esophagitis, collagen vascular disease, hypereosinophilic syndrome and eosinophilic gastroenteritis.
• Previous or current diagnosis of cancer or leukemia.
• History of chemotherapy within the past 3 months.
• History of esophageal stricture or food impaction.
• History of anaphylaxis or other severe adverse reaction to the specific food trigger being tested.
