Occupational IgE-mediated asthma, rhinoconjunctivitis, and contact urticaria caused by Easter lily (Lilium longiflorum) and tulip.
We report on IgE-mediated asthma, rhinoconjunctivitis, and contact urticaria to two Liliaceae plants, tulip and Easter lily (Lilium Iongiflorum), diagnosed in a floral shop worker.
Occupational asthma was diagnosed according to patient history, PEF monitoring, and a work-simulating provocation test.
Flower-specific IgE was studied, and RAST inhibition tests were performed.
Skin prick testing showed positive reactions to tulip, Easter lily, and chrysanthemum.
Total IgE was 180 kU/l, and specific IgE to tulip was 2.6 and to Easter lily 6.5 kU/I. In the RAST-inhibition test, no cross-reactivity was found.
Occupational asthma was diagnosed by peak flow monitoring at work and at home, as well as specific inhalation challenge with Easter lily, with an immediate 18% reduction in PEF.
In addition, contact urticaria and conjunctivitis were diagnosed.
After a 9-year follow-up without exposure to lilies, the skin prick tests to L. longiflorum and tulip were still positive, but the specific IgE had disappeared.
A case of IgE-mediated occupational asthma, rhinoconjunctivitis, and contact urticaria caused by L. longiflorum and tulip is presented.
RAST inhibition tests indicated concomitant sensitization to the two Liliaceae plants.
