The Effect of Per Oral Immunotherapy in Severe Milk, Peanut and Egg Allergy in Adults

30 patients with milk allergy (at least 18 year olds), 30 patients with peanut allergy and 30 patients with egg allergy are treated with OIT. The diagnosis of food allergy is verified with positive history, skin prick test, egg and milk allergen specific IgE antibodies. In addition, food allergy is verified with an open label (milk allergy) or blind (peanut and egg allergy) allergen specific challenge test. Quality of life, anxiety and patient history data is collected by questionnaires. All the patients undergo a spirometry with a bronchodilatator test, exhaled nitric oxide test and a methacholine challenge before and a year after oral immunotherapy. All the patients undergoing oral immunotherapy are prescribed with emergency medication such as antihistamine tablets, prednisolon tablets (40mg for three days in adults), epinephrine autoinjector (300 µg per dose) and salbutamol or terbutaline inhalator.
