摘要

A 58-year-old atopic man was referred to our outpatients' clinic because of four episodes in 3 years of severe anaphylaxis with urticaria, angio-oedema and finally loss of consciousness within a few minutes after consumption of a sandwich or toast with Gouda cheese. Detailed history, quantification of specific IgE (slgE) and skin tests confirmed allergy for house dust mite and cat epithelium. There was neither evidence of a classical IgE-mediated food allergy (in particular, wheat and diary products) nor of pollen or latex allergy that could have explained a secondary food allergy. Serum tryptase level was normal at the clinical visit. Careful revision of labels from different brands of Gouda cheese revealed that the reaction could potentially be elicited by the natural dye annatto (E160b).
