Airborne olive pollen counts are not representative of exposure to the major ol...

CecchiPollen is routinely monitored, but it is unknown whether pollen counts represent allergen exposure. We therefore simultaneously determined olive pollen and Ole e 1 in ambient air in C ordoba, Spain, and Evora, Portugal, using Hirst-type traps for pollen and high-volume cascade impactors for allergen. Pollen from different days released 12-fold different amounts of Ole e 1 per pollen (both locations P < 0.001)....
Grass Pollen Count and Grass group 5-allergen Release across Eight European Cou...
Buters, Jeroen M.; Albertini, Roberto; Annesi-Maesano, Isabella; Antunes, Celia M.; Berger, Uwe; Brandao, Rui M.; Cecchi, Lorenzo; Celenk, SevcanBackground: Grass pollen is considered to be the most important outdoor aeroallergen in Europe. The grass ‘pollen count’ is usually used as a proxy for exposure. However, HIALINE has shown that the birch and olive pollen count is not always congruent with allergen concentrations. We therefore simultaneously measured daily exposure to grass pollen and the concentration of group 5 major allergens across eight cou...
Release of Bet v 1 from birch pollen from 5 European countries. Results from th...
Buters, Jeroen T.M.; Thibaudon, Michel; Smith, Matt; Kennedy, Roy; Rantio-Lehtimäki, Auli; Albertini, Roberto; Reese, Gerald; Weber, BernhardExposure to allergens is pivotal in determining sensitization and allergic symptoms in individuals. Pollen grain counts in ambient air have traditionally been assessed to estimate airborne allergen exposure. However, the exact allergen content of ambient air is unknown. We therefore monitored atmospheric concentrations of birch pollen grains and the matched major birch pollen allergen Bet v 1 simultaneously ac...
