Anaphylaxis to cabbage: detection of allergens.
Allergy to cabbage and other foods in the Brassica family has rarely been observed in man. We report a case of facial and throat swelling in an atopic female after she ingested coleslaw on two separate occasions. She had 4+ reactions to cabbage, mustard plant, cauliflower, and broccoli by skin testing. A RAST using cabbage extract was positive for specific IgE antibody. Analysis of cabbage extract by gel filtration showed five peaks of ultraviolet-absorbing material at 280 nm. Allergenic activity was demonstrated by RAST inhibition in two fractions of the cabbage extract. This report confirms IgE sensitivity can occur to foods in the Brassica family.
