Successful management of severe cow's milk allergy with omalizumab treatment and CD-sens monitoring.

Food allergy is common in children and young adults and may be difficult to diagnose and is at present treated with avoidance of the food in question. The aim of this report is to share our clinical experiences monitoring omalizumab treatment by basophil allergen threshold sensitivity, CD-sens. Five children, 6-16 years of age, with a severe milk allergy including episodes of anaphylaxis and IgE-antibodies, between 30 and 160 kUA/L to casein and alpha-lactalbumin (milk proteins), were treated with omalizumab.
