High frequency of IgE sensitization towards kiwi seed storage proteins among peanut allergic individuals also reporting allergy to kiwi.

Background: IgE sensitization to storage proteins from nuts and seed is often related to severe allergic symptoms. There is a risk of immunological IgE cross-reactivity between storage proteins from different species. The potential clinical implication of such cross-reactivity is that allergens other than the known sensitizer can cause allergic symptoms.

Affinity purification of egg-white allergens for improved component-resolved diagnostics.

Background: Egg is a common cause of food-allergic reactions, especially among young children. Some egg-allergic patients do, however, tolerate heated egg products and component-resolved diagnostics (CRD) may facilitate prediction of different disease manifestations. Commercially available preparations of the egg-white allergens, ovomucoid, ovalbumin, conalbumin and lysozyme, have been reported to contain impurities which interfere with accurate CRD.
