Eosinophilic esophagitis (EoE) is a clinicopathologic disorder of the esophagus triggered by food and/or environmental allergens and is characterized by symptoms of esophageal dysfunction and eosinophilia of the esophagus. Current therapy is centered on controlling inflammation with steroids and/or food antigen avoidance. Such treatment options have significant side effects and reduce quality of life, especially in children. The purpose of the study is to discover a way for flare-provoking foods to be reintroduced into the child's diet without the need for medical therapy.
The study would involve children ages 3-17 years with biopsy-proven EoE who have a known flare-inducing food trigger. Following baseline blood work and esophagogastroduodenoscopy (EGD), the investigators will initiate oral desensitization treatment in which the child swallows a spray solution containing his or her specific food allergen extract in increasing concentrations twice daily for 4 months. The next phase of the study would involve reintroduction of the actual food for 4 weeks followed by repeat blood work and EGD. Success would be defined by having a peak eosinophil count <15 per high power field on the final esophageal biopsy.
Oral food desensitization has been well-studied in patients with food allergies but never in patients with pre-existing EoE. In those studies, the adverse events included mild reactions, such as watery eyes, rhinitis, sneezing, throat pruritus, transient erythema and abdominal pain. These reactions usually did not require stopping desensitization and were well controlled by antihistamines and steroids. Benefits include children having a less restricted diet and eliminating the need for steroid therapy. This study should yield valuable information regarding the management of EoE, thereby improving the current understanding of its pathogenesis.

Experimental: Oral food desensitization
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
The child's specific food antigen will be diluted in a 50% glycerin/water solution containing ascorbic acid (Vitamin C). This oral spray solution will need to be administered twice a day, every day for a total of 4 months
- Peak eosinophil count on esophageal biopsy [ Time Frame: 5 months ]Remission of esophageal eosinophilia as defined by having <15 eosinophils per high power field on peak esophageal biopsy
