摘要

Patients with elevated serum tryptase/mastocytosis are at risk for severe and fatal reactions following hymenoptera stings and can be unable to undergo venom immunotherapy because of intolerable side effects. We report the first case of a patient with indolent systemic mastocytosis and recurrent severe anaphylaxis to field stings and to venom immunotherapy, in whom a single dose of 150 mg omalizumab enabled ultra-rush honey bee venom immunotherapy. Immunotherapy (IT) with hymenoptera venom reduces the risk of anaphylaxis with subsequent stings and is recommended in patients with systemic reactions and evidence of venom-specific IgE. Treatment with honey bee venom (HBV) induces anaphylactic reactions more frequently than yellow jacket venom [1]. Patients with elevated basal serum tryptase levels/mastocytosis are at risk for more-severe and even fatal reactions following stings and may be unable to undergo venom IT [2, 3].We report the first case of a patient with indolent systemic mastocytosis and recurrent severe anaphylaxis to field stings and venom IT, in whom a single dose of omalizumab enabled ultra-rush IT within two days [4] with a total dose of 351.11 mg HBV (ALK SQ, Abello, Horsholm, DK). Thereafter, ten maintenance doses of HBV (100 mg) were tolerated.
