Abstract

We report the case of a 38-year-old man who was bitten several times during his life by a tick. He didn't report any previous history of anaphylaxis after the ingestion of red meat. The serum specific IgE showed positivity to α-Gal. The proximity of the bits didn't increase the titer of IgE antibodies to alpha-gal. We could hypothesize that the frequency of the exposure to the tick Corresponding author bites and the amount of tick bites during his lifetime induced a sort of tolerance in this patient.

Keywords: basophil activation test; delayed food anaphylaxis; hunter; sIgE to α-Gal; tick bit.
