Method of treating eosinophilic esophagitis
The present invention relates to the treatment of EE. More specifically, the invention relates to a new method of treating EE through the epicutaneous route. In particular, the method of the invention comprises applying to the skin of the subject a skin patch device, comprising a composition, under conditions allowing a contact between said composition and the skin. The present invention also relates to the skin patch device and to a use of the skin patch device in the manufacture of a composition for treating eosinophilic esophagitis in a subject.
1. A method of treating a food-induced eosinophilic esophagitis in a subject, said eosinophilic esophagitis being characterized by an eosinophilic infiltration in the subject, the method comprising epicutaneously applying to the skin of the subject having eosinophilic infiltration a non-perforating skin patch device comprising a composition comprising, as the only active ingredient, a food allergen under conditions allowing contact between said composition and the skin, and in an amount sufficient to cause a decrease of eosinophilic infiltration in an esophagus or gut of the subject, said application resulting in a treatment of said eosinophilic esophagitis.
2. The method of claim 1 , wherein said subject suffers from allergy to one or more food allergens.
3. The method of claim 1 , wherein the food allergen is selected from the group consisting of milk, egg, wheat, soja, and peanuts.
4. The method of claim 1 , wherein more than one allergen is epicutaneously applied on the skin via one or more patch devices, separately, successively or simultaneously.
5. The method of claim 1 , wherein the composition is in dry form.
6. The method of claim 1 , wherein said method involves a repeated application of the skin patch device.
7. The method of claim 1 , wherein said composition further contains a pharmaceutically acceptable carrier.
8. A method of decreasing eosinophilic infiltration in an esophagus or gut of a subject having eosinophilic infiltration, said method comprising epicutaneously applying to the skin of the subject a non-perforating skin patch device comprising a composition comprising, as the only active ingredient, a food allergen under conditions allowing a contact between said composition and the skin, said application resulting in a decrease of eosinophilic infiltration in the esophagus or gut.
