METHODS OF PREVENTING OR TREATING ALLERGIES

摘要

The present invention relates to methods and means of suppressing food-induced hypersensitivity reactions in patients suffering from food allergy. Particularly the invention provides methods of making a protein hydrolysate formula for downregulating hypersensitivity reactions and for promoting gut immune barrier, and methods of preventing or treating allergies, especially cow's milk allergy in infants by fortifying the cow's milk elimination diet with suitable probiotic bacteria derived from gastrointestinal tract, especially Lactobacilli. In addition, administering fragments of an allergen modified by gastrointestinal bacteria immune response can be "turned around" from sensitization to systemic hyporesponsiveness. A preferable bacterium to be used in this invention is Lactobacillus GG (ATCC 53103).
