Outdoor airborne allergens: Characterization, behavior and monitoring in Europe
Grewling, Lukasz; Ribeiro, Helena; Antunes, Célia; Apangu, Godfrey; Çelenk, Sevcan; Costa, Ana; Eguiluz-Garcia, Ibon; Galveias, Ana; Roldan, NestorAeroallergens or inhalant allergens, are proteins dispersed through the air and have the potential to induce allergic conditions such as rhinitis, conjunctivitis, and asthma. Outdoor aeroallergens are found predominantly in pollen grains and fungal spores, which are allergen carriers. Aeroallergens from pollen and fungi have seasonal emission patterns that correlate with plant pollination and fungal sporulation...
Automatic detection of airborne pollen: an overview
Buters, Jeroen; Clot, Bernard; Gehrig, Regula; Gilge, Stefan; Hentges, François; O’Connor, David; Sikoparija, Branko; Skjoth, Carsten; Tummon, FionaPollen monitoring has traditionally been carried out using manual methods first developed in the early 1950s. Although this technique has been recently standardised, it suffers from several drawbacks, notably data usually only being available with a delay of 3–9 days and usually delivered at a daily resolution. Several automatic instruments have come on to the market over the past few years, with more new devic...
Variation of the group 5 grass pollen allergen content of airborne pollen in re...
Buters, Jeroen; Prank, Marje; Sofiev, Mikhail; Pusch, Gudrun; Albertini, Roberto; Annesi-Maesano, Isabella; Antunes, Celia; Behrendt, HeidrunBackground: Allergies to grass pollen are the number one cause of outdoor hay fever. The human immune system reacts with symptoms to allergen from pollen. Objective: We investigated the natural variability in release of the major group 5 allergen from grass pollen across Europe. Methods: Airborne pollen and allergens were simultaneously collected daily with a volumetric spore trap and a high-volume cascade impa...
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 acr...
