Food hypersensitivity is a syndrome of clinical disorders, which are caused by the intake of various, specific kinds of food or different chemical substances present in the food. It can either activate immunological mechanisms (food allergy) or not. The frequency of allergic disorders has been steadily increasing recently. The symptoms usually show up in early infants (allergy to cow’s milk). In the following years apart from food allergy, inhalator pathogens start playing more and more important role. The clinical picture of food allergy changes into “the allergic march”. The most common kind of allergy in infants and small children is the cow’s milk allergy. In the clinical manifestation of food hypersensitivity to cow’s milk protein the skin manifestation can be observed most frequently, the next characteristics being motoric disorders in the lower and upper part of the digestive system, ileitis and colitis, which are caused by food and eosinophilic inflammation in the mucosa of the digestive system. Food allergy to cow’s milk protein can also be manifested with respiratory symptoms or general bodily disorders. The treatment is based on eliminating the badly tolerated food product from the diet and replacing it with a well-tolerated food product with the same nutric value. The aim of thework is to present the two clinical cases of food allergy to cow’s milk in infants: the boy with the severe kind of atopic dermatitis and the girl with eosinophilic enteritis. The patients were firstly treated with hypoallergenic kinds of milk – getting no good clinical results. However, after administering the basic preparations as well as applying pharmacological treatment the condition of the patients improved.
