Allergic symptoms (patient history), specific and total IgE (ImmunoCAP analyses) of all patients investigated.

Allergic symptoms after contact with potato, tomato or hymenoptera venoms are listed according to patient history. Contact urticaria (CU, after direct contact with raw potato or tomato) was classified from 1 to 4 according to von Krogh and Maibach [51]. Total and specific IgE levels were measured with the UniCAP100 instrument (Phadia) using either commercial ImmunoCAPs for tomato (f25), potato (f35), HBV (i1), YJV (i3), HRP (o400), and MUXF (o214), or in-house-made ImmunoCAPs (wt and GTI). Specific IgE values ≥0.35 kU/l were considered positive.*Borderline patients due to negative MUXF-sIgE and borderline positive HRP-sIgE levels.#Recently stung by a honeybee but without allergic symptoms.‡For CCD inhibition with HRP, see Table 2. (BW: bee/wasp hymenoptera venom-allergic; CU: contact urticaria; GI: gastro-intestinal symptoms; GTI: GNTI-silenced; HBV: honeybee venom; HRP: horseradish peroxidase; HV: hymenoptera venom; MUXF: N-glycan structure according to the proglycan system (www.proglycan.com); NA: non-allergic control; OAS: oral allergy syndrome; PT: potato/tomato-allergic; RC: rhinoconjunctivitis; systemic: systemic reaction; wt: wild-type; YJV: yellow jacket venom).
