The small cross-sectional study on 100 school children in Grabs at a 20-year interval showed a marked increase in sensitization to the molecular PR-10 allergens, in particular the alders (rAln g 1). 2006;29:231–5. Only in this way is it possible to assess secondary phenomena, in particular the effects of climate conditions and harmful organisms, such as the epidemic caused here by an imported mutant fungus Hymenoscyphus fraxineus. Both young and old ash trees belonging to the Fraxinus excelsior species are affected. - Their immunological response is different [27]. In 2010, sensitizations to Fraxinus were also measured: seven subjects tested positive to nOle e 1: four with high titers (>1.4 ISU) in both study years, while three first showed sensitization in 2010 (3.9; 1; 0.4 ISU). Immunotherapy is a long-term treatment that can help prevent or reduce the severity of allergic reactions. Pollen allergy that is left untreated for a lengthy period of time can develop into allergic asthma, which is known as progression. In the CAP test, 5 students had positive values to Fraxinus excelsior (t25) (>0.7 kU/l) of between 0.97 and 13.9 kU/l and four had values below the cut-off of 0.35 kU/l (0.04–0.23). Tree pollen allergies are seasonal, mainly occurring between February and June. Every year, IgE antibodies to the following major allergens were determined using current methods (RAST/CAP): timothy grass (g6), birch (t3), house dust mite (d1), and cat (e1). IgE antibodies to a sum of allergens from the corresponding pollen were investigated in the CAP tests. Common allergens could be determined in the high molecular weight region. There are years with virtually no measureable pollen level, followed by 4 years with some extremely high pollen levels. It is very difficult to judge in polysensitized individuals which pollen levels cause which symptoms, since the most important trees in terms of allergy—birch and ash—bloom almost simultaneously in Switzerland: the ashes usually only for a few days, but sometimes up to 2 weeks before or after birch trees [21]. Its pollen is relevant not only to hikers, but also to inhabitants of urban areas further away at the edge of the Alps. Get 5 Day Allergy Forecast for Kerrville, TX (78028). The roots are packed in jute and transported on palettes made from international wood. Allergo J Int. Since annual fluctuations in ash pollen levels are considerable yet unpredictable, standardized pollen data over decades are needed (Fig. In order to correctly diagnose an allergy, especially with regard to specific immunotherapy, a correlation between a patient’s symptoms and exposure, as well as qualitatively optimal identification of the corresponding sensitization, is crucial. This dents confidence in recommendations for a healthy diet (fruit and vegetables). Allergen exposure in urban areas is of great importance from an epidemiological point of view, but extremely difficult to measure. However, one of 12 individuals clearly showed new sensitization to the major allergen nOle e 1. Initially, only Fraxinus americana (t15) was commercially available for serological testing using the CAP assay, with the reagent Fraxinus excelsior (t25) being available only from 2006 onwards [8]. Ash Allergy Info Most species of ash are major offenders in spring pollinosis. Note that the list includes taxa relevant for pollen allergies such as two different Betulaceae, Dactylis glomerata as a proxy for grasses, and ash. This should be taken into account not only when selecting plants (trees and shrubs) for urban areas, but also fruits, if only due to pollen sensitizations. Bozen: Biologisches Labor der Landesagentur für Umwelt und Artenschutz; 2004. Variety-specific differences have also been described in olive pollen [25]. The disease has also been evident in Eastern Switzerland since 2011 (pollen measuring stations: Buchs [St. Gallen] and Münsterlingen). The greenish yellow flowers first appear in early spring and are followed by winged seeds that drop in the fall. Ash pollen (Fraxinus) March to May, peaking in April. Allergy to ash pollen is common in some parts of Europe. Birch pollen is highly allergenic and is a significant cause of asthma and rhinoconjunctivitis. The search for a new allergen source revealed the extremely high pollen count along the regional promenade between Christmas and New Year due to Spaeth’s alders, 1–2 months before the release of pollen from indigenous alders (Alnus glutinosa, Alnus incana). 2. Environ Res. More subjects in the cohort reacted to Fraxinus excelsior (t25) in the CAP test than to Fraxinus americana (t15). This applies in particular to allergies to hazel, alder, and birch pollen. Hay fever, also known as allergic rhinitis, doesn’t have anything to do with a fever, or hay for that matter. For this reason, they are used as a surrogate for sensitizations to ash pollen. In contrast to the Fagales, the ash influorescences are virtually impossible to assess phenologically prior to flowering. Among the Oleaceae, pollen from Fraxinus ornus (manna ash) is popular [19]. 2000;16:353. Ash pollen allergies as a subtype of Hay fever Hay fever (medical condition): An allergy which causes sneezing, runny nose or blocked nose for part of the year. Pediatr Allergy Immunol. Likewise, these anthropogenically planted trees in urban areas cannot be recorded using individual, distant pollen measuring sites [3]. Green ash. The years with low levels have been occurring at all locations in Switzerland in a coordinated manner for 20 years, whereas there are significant regional fluctuations for years with high levels. Targeted selection of more resistant and better sustainable plants and livestock in agriculture is essential for food production. Green ash leaves This small comparable group (n = 12) followed for over 24 years revealed that the majority have kept the same sensitization pattern (pollen or house dust mites, animal danders) from the time prior to adolescence. Hay fever (medical condition): Hay fever is a common nasal allergy to airborne substances such as pollens or molds, and the term has also been used for other allergies such as to animal dander. Dtsch Med Wochenschr. Ash trees can grow up to 90 feet tall and resist insects and disease. The Benefits Of Local Pollen Reports. Article  Pollen - National Institute of Environmental Health Sciences Triggers of hay fever are broad-leaved trees in early summer, grasses in high sum-mer and mugwort in late summer. Knowledge of molecular cross-reactions (in this case ashes–olives) is important for migrants and travelers.

Oleaceae (olive family) pollen allergy is common. This trend is difficult to interpret and, as a result, prognostic calculations are becoming ever more speculative. Symptoms of pollen allergies can last all day or can be worse at certain times of the day. Ashes were problematic in the forest 20 years ago due to their rapid propagation and also due to storm damage; they were considered the “weed of the forest.” Back then, an “ashification” of the forest was feared [22]. The wall of the pollen grain (the exine) is described as reticulate (net-like) and the grains are 18-28 microns in size. She herself had exhibited sensitization only to plane pollen (Pla a 2) in the ISAC test in 1996. 2013;368:393–4. Emissions of molecular allergens from these plants represent the essential criterion of quality for the health of allergy sufferers. "Allergy friendly" trees include: ash (female only), red maple, yellow poplar, dogwood, magnolia, double-flowered cherry, fir, … Trend in the annual pollen integral (APIn) measured in a standardized manner at all measuring sites in the Swiss network of pollen measuring sites. Allergologie. The pollen forecast levels are determined from sample collections taken at 32 local ... Answering the Internet’s Top 5 Allergy Questions. D’Amato G, Cecchi L, Bonini S, Nunes C, Annesi-Maesano I, Behrendt H, et al. Oleaceae (olive family) pollen allergy is common. In all, 12 former students who had reacted positively to one of the four major allergens in the 1986 CAP test were invited to repeat serology testing in 2010 using the ISAC test (cohort study). In line with this, genetic investigations (associative transcriptomics) revealed identical characteristics in species known to be resistant (Fraxinus americana, Fraxinus ornus), and now also to a certain extent in surviving resistant types of ash tree in Denmark (Fraxinus excelsior) [15]. Local environmental conditions significantly limit the survival time of urban trees. Allergy to ash pollen, for example, is well known in Switzerland [7,8,9,10,11]. The role of the “major and minor allergens,” e.g., IgE to profilins, polcalcins, and in particular nonspecific lipid transfer proteins (nsLTPs) in most tree pollen (Fagales, Oleaceae, Platanaceae, Ailanthus, Castanea, etc.) Aerobiologia. To stem the flood, Phoenix passed the Airborne Pollen Ordinance which restricted the planting of male Mulberry and Olive trees. Background: Sensitization to ash pollen is underestimated in various regions. Only the subject with the highest titer still had a titer of 1.6 ISU in 2010 (not shown in detail here). In urban areas where people live and work, nonindigenous varieties and species of trees that also release pollen with a high risk for causing allergies are most commonly planted. Horticultural companies recommend planting these green alders in northern Germany—even to stabilize slopes. No further increase in asthma, hay fever and atopic sensitisation in adolescents living in Switzerland. However, allergy to ash pollen is widely overlooked by allergists, since the pollination period of ash and birch in central Europe closely overlap and rhinoconjunctival symptoms during April/May are often assigned to birch pollen. Of these, 102 (16.3%) showed specific IgE (>0.7 kU/l). Ash (Fraxinus) Family: Olive Family (Oleaceae) ... on the location one may distinguish slow growing “lime – ashes” and faster growing “water – ashes”. Ash, ON . Pollen seasons can last for several months and exposure is difficult to avoid. The prevalence in Germany is about 10%. Article  Fagales pollen contains rBet v 1 as its “major molecular allergen,” with its various cross-reactions to other PR-10 proteins (pathogenesis related protein family 10). The determination of IgE to common ash (Fraxinus excelsior) is more sensitive than to American ash (Fraxinus americana). The Allergy Outlook is unavailable for your location.Set your default location. IgE levels to pollen from indigenous ash (Fraxinus excelsior t25) were higher than to pollen from American ash (Fraxinus americana t15). Plan you week with the help of our 10-day weather forecasts and weekend weather predictions for Romoos, Lucerne, CH Patients sensitized to birch and ash pollen often respond less well to hyposensitization with birch pollen alone [8].
