Results Median age: 10.6 years. Median maintenance period: 1.5 years. CM-IgE before SOTI: 101 KU/L. Median threshold dose at oral food challenge before SOTI: 2.5 ml. Median current daily CM dose: 200 ml. Allergic reactions to CM: 29 children have had reactions, as follows: A) Non anaphylactic reactions: 15 children. 8 children suffer daily from mild symptoms (4, mouth itching; 1, abdominal pain; 1, hives; 2, rhinitis) and 4 children from mild asthma 2-3/week, with no triggers associated. 6 children had 1 to 6 mild respiratory or digestive symptoms related to trigger factors.
