Improvement of Foodallergy Diagnostic in Gastrointestinal Tract

Improvement of Foodallergy Diagnostic in Gastrointestinal Tract With a New Kind of Sampling

Currently, diagnostic possibilities for the detection of food allergy in the gastrointestinal tract are scarce. The endoscopic segmental Lavage is the method of choice, but it´s controversial.

Additional to the endoscopic segmental lavage fluid a cytobrush is used for collecting the mucosa cells and biopsies are taken. Comparative to the Lavage specific IgE antibodies, Tumor necrosis factor- alpha, Eosinophilic cation protein and mastcell tryptase were measured.

Inclusion Criteria:

• all patients with suspicion of food intolerance and confirmed food allergy

Exclusion Criteria:

• pregnant and patients under allergy medication (antihistaminic, cortison)
