THE HYMENOPTERA VENOM STUDY .2. SKIN-TEST RESULTS AND SAFETY OF VENOM SKIN TESTING

[摘要] Data are summarized in this Hymenoptera venom study (HVS) article on the safety of skin testing with venom extracts. Of the 3236 subjects studied, 89% had experienced an historical sting systemic reaction (SSR). Seventy-four percent of all subjects and 76% of subjects who had experienced an historical SSR had a positive skin test to at least one venom. More subjects tested positive to yellow jacket venom (51.8%) than to any other venom. There were no significant differences of the wheal and erythema sizes associated with different venoms or different historical sting reactions. Forty-five percent of subjects with positive venom skin tests (VST) were positive to wasp, and 89% of these subjects were also positive to at least one of the following venoms: yellow hornet, or white-faced hornet. Sixty-four of the 3236 subjects studied (2%) had a systemic reaction (SR) during VST; 13 of the SRs (0.4%) were severe. Thirteen of 64 adverse reactions (20%) were possibly vasovagal, and six other subjects (9%) demonstrated no symptoms of immediate-type hypersensitivity. Thus, 45 (1.4%) of the 3236 subjects tested had an SR that was considered to be a reaction of hypersensitivity, of which eight reactions (0.25%) were severe. Allergic SRs are associated with VST but are unusual and are rarely severe.
