DIAGNOSTIC PREDICTORS OF TOLERANCE DEVELOPMENT IN THE ELIMINATION DIET IN CHILDREN WITH COW'S MILK PROTEIN ALLERGY

Abstract

Background. Cow's milk protein allergy is a topical issue in pediatrics. This disease affects 2-3% of young children. Methods. The study included 30 children with a confirmed cow’s milk protein allergy and a prescribed milk elimination diet. The children were observed for 36 months. The molecular profile was evaluated by detecting the major components of milk (Bos d 8, Bos d 5, Bos d 4), minor (Bos d 6), and cross-reactive with serum albumin (Fel d 2, Can f 3). Results. The study group included 46.7% of boys. The mean age of the subjects was 14.5±3.18 months. Nine of the 25 analyzed factors were identified in the course of our work by the method of logistic regression with progressive selection, which in combined action affect the formation of tolerance to cow's milk proteins in allergic children. There are three clinical examples of calculating the prediction of the complete tolerance development in the elimination diet in children with cow's milk protein allergy. Conclusions. Independent predictors that reduce the likelihood of the tolerance development in the elimination diet, have identified: skin test to milk, Bos d 8, Bos d 5, Bos d 4, Bos d 6. Independent predictors of the tolerance development in the elimination diet are: milk-specific IgE, total IgE, Fel d 2, Can f 3. Low probability of tolerance development by elimination therapy is a recommendation for prescribing treatment to a patient by specific oral tolerance induction.
