성인에서 발생한 우유 알레르기 환자에서 쇠고기와 돼지고기 알레르기를 동시에 나타낸 환자 1예

초록

Cow`s milk has been recognized for many years as one of the leading causes of food allergy. The prevalence of cow`s milk allergy is reported to be 1% to 2%. It has been reported that 13∼20% of milk allergy children react to beef. We experienced a case of 47-year-old female patient presenting with severe food allergy symptoms including abdominal pain, dizziness, dyspnea, nasal stuffiness and vaginal spotting 2∼3 hours after ingestion of cow`s milk, beef, or pork which developed 8 months ago. Laboratory findings showed high total IgE levels (1,295 kU/L) and high specific IgE levels to milk, beef, and pork (3.04 kU/L, 9.26 kU/L, and 4.58 kU/L, respectively) using the immuno-CAP system, while allergy skin tests for milk, beef, and pork showed negative results. In bovine serum albumin (BSA) IgE ELISA test, the patient showed a high serum specific IgE binding activity to the BSA compared to healthy controls. She received regular inhaled corticosteroid and antihistamines and restricted ingestion of cow`s milk, beef and pork meats. We report a rare case of adult-onset milk allergy showing concurrent reactivity to beef and pork. (Korean J Asthma Allergy Clin Immunol 2007;27:200-203)
