Common allergenic structures in hazelnut, rye grain, sesame seeds, kiwi, and poppy seeds.

Allergy to kiwi, poppy seeds, and/or sesame seeds often occurs in patients with a simultaneous sensitization to nuts and flour. Previously cross reactions have been verified by RAST inhibition. In this study the nature of this cross-reactivity is further characterized by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), followed by immunoblotting to nitrocellulose. The degree of cross-reactivity among kiwi, sesame seeds, poppy seeds, hazelnuts, and rye grain was found to be very high in the patients studied. The existence of both cross-reacting and unique components was observed; however, the cross-reacting and unique components could be different for different patients.

[Immunoglobulin E-mediated contact urticaria and bronchial asthma caused by household rubber gloves containing latex. 3 case reports]. / Immunglobulin E-vermittelte Kontakturtikaria bzw. Asthma bronchiale durch Latex-enthaltende Haushaltsgummihandschuhe. Drei Fallberichte.

During a period of a few months we observed 3 female patients suffering from contact urticaria by use of rubber gloves. In one case the local urticarial reaction at the fore arms was followed by asthma. In all 3 cases we could prove type I allergy against latex by radio allergo sorbent test (RAST).
