Abstract:
Serum specific IgE antibodies for non-primate mammalian carbohydrate galactose-α-1,3-galactose (α-Gal) are associated to
α-Gal syndrome: delayed allergy to red meat manifested as anaphylaxis, angioedema or urticaria after ingestion of beef, pig
or lamb meat, immediate-onset anaphylaxis at first parenteral exposure to drugs significantly containing α-Gal. IgE-mediated
drug allergy in the α-Gal syndrome was reported for some therapeutic monoclonal antibodies, such as cetuximab, snake
antivenom, and varicella-zoster vaccine, but there are risks also for colloid plasma volume substitutes, vaccines containing
gelatine of porcine/bovine animal origin as an excipient, and drugs with porcine pancreatin or bovine-origin magnesium stearate.
