Abstract | BACKGROUND: CASE REPORT: We report on a 22-year-old male with severe cow's milk allergy with multiple anaphylactic reactions, known since infancy and persisting into adulthood with sometimes severe immediate-type reactions on accidental ingestion. The prick test for native whole milk was positive, the CAP-FEIA was also positive for milk protein, mare's milk, whey, sheep's milk whey as well as Bos d4, Bos d5, and Bos d8 and blue cheese; total IgE was 1,265 kU/L. The patient's history included well-controlled bronchial asthma. An off-label therapy with omalizumab (3 × 150 mg/month SC) and cetirizine 10 mg once daily was initiated. Under this therapy, we performed a double-blind oral exposure test to cow's milk in the patient after long term. Thereby 14 mL could be tolerated. After consumption of 30 mL of cow's milk, urticaria, dyspnea, and angioedema occurred. CONCLUSION: Under therapy with omalizumab, an increase of the tolerance to cow's milk was shown in our patient. As a consequence, reactions during accidental consumption could be prevented.
