Cow's milk allergy in an adult patient

A 22-year-old female patient is described who was repeatedly hospitalised on account of severe asthmatic attacks presumably due to the ingestion of cow's milk or milk-containing products. There were no signs of gastrointestinal disturbance, but some urticaria and angioedema occurred. Strongly positive RASTs were observed in the blood serum against the proteins in cow's milk, bovine serum, egg white, cod fish, and house dust. The symptoms were successfully controlled by rigorous dietary measures.
