“…Similar trends in the course of lime pollen seasons were reported in a 10-year study conducted in Denver (Colorado, USA) [17]. The investigations also showed an accelerated onset of the pollen season of this taxon and an increase in the pollen concentration.…”

Analysis of the concentration of Tilia sp. pollen in selected Polish cities in 2020

With their numerous natural and functional values, lime trees are recommended for planting in urban greenery. However, the allergenic properties of lime pollen should be taken into account. The aim of the study was to analyze the concentration of airborne lime pollen and the course of pollen seasons in this taxon in 10 cities in Poland in 2020. The aerobiological analyses were carried out in Bialystok, Bydgoszcz, Cracow, Lublin, Olsztyn, Opole, Piotrkow Trybunalski, Sosnowiec, Szczecin, and Warsaw. The investigations were conducted with the volumetric method using Burkard or Lanzoni pollen samplers. The 98% method was employed to determine the length of the pollen season. The earliest onset of the lime pollen season was recorded in Opole and Warsaw (June 14th), and the latest date was noted in Sosnowiec (June 23rd). The maximum lime pollen concentrations were reported between July 1st and July 6th in most cities and on June 24th only in Lublin and Opole. The highest annual pollen sums were recorded in Lublin (738), similar to those reported in 2018 and 2019, whereas the lowest values were noted in Bialystok (20), Sosnowiec (145), and Olsztyn (149). The annual sums of lime pollen in the other measurement sites located in the different regions of Poland were in the range of 180–308. In the discussion, the results from 2020 for Lublin are compared with data from the previous 19 years collected in this city. The data suggest that the increase in the airborne lime pollen concentration recorded in Lublin in recent years may be associated with climate change.

“…A study by Grewling et al [ 54 ] reveals that daily concentrations of Betula pollen significantly increased on days with high mean temperatures. In many countries in Europe and the USA, a trend has been observed towards an earlier start of the pollen season in connection with climate change [ 4 , 18 , 21 , 55 , 56 ]. Moreover, Buters et al [ 57 ] found that temperature has a direct effect on Betula allergen release.…”

Analysis of changes in Betula pollen season start including the cycle of pollen concentration in atmospheric air

et al. 2021

Birch belongs to the most important allergenic taxa in Europe, therefore information on the start dates of the pollen season is very important for allergists and their patients as well as for climatologists. The study examined changes in the start of the birch pollen season as well as determined the trend of these changes. Pollen monitoring was performed in Lublin (eastern Poland) in the period 2001–2019 using the volumetric method. The Makra-test was used to detect periods with significantly higher or lower average of the onset than the average for the whole dataset. Two significant falls in the average of the pollen season start were found in 2007 and 2014. Besides, taking into account the 2-3-year rhythm of high and low concentrations of birch pollen in the atmospheric air, linear trends were fitted for the subsets of high and low abundance seasons. Significant changes in Betula pollen season start dates were only determined for the highly abundance seasons, while the results for seasons with a low concentration did not allow rejecting the hypothesis about the lack of a linear trend in the changes in the studied parameter. Moreover, a significant polynomial relationship was found between the beginning of a pollen season and the average values of monthly temperatures preceded a season. These analyses show that the start dates of the Betula pollen season are getting significantly earlier. The dynamics of changes differ between seasons with high and low concentrations of pollen.

“…The major sensitizing pollen allergen involved in PFS in Northern Europe is birch tree pollen ( Betula verrucosa ); 66% of birch‐allergic UK adults and 48% of children have PFS, with the overall UK prevalence of PFS in an unselected adult population being 2% (range 1–4% depending on geography) 1,2 . The lengthening of the pollen season, prevalence of more allergenic pollen due to rising temperatures and increased severity of SAR all contribute to the growing prevalence of PFS in all ages 13–16 . In addition to SAR, other co‐morbidities associated with PFS are asthma, eczema (commonly in children) and gastro‐intestinal conditions such as irritable bowel syndrome (IBS) and eosinophilic oesophagitis (EoE) 17–20 …”

Pollen food syndrome (PFS) is a highly prevalent food allergy affecting pollen‐sensitized children and adults. Sufferers experience allergic symptoms when consuming raw plant foods, due to the homology between the pollen allergens and unstable proteins in these foods. The triggers involved can vary depending on the pollen sensitization, which in turn is affected by geographical location. The British Society of Allergy and Clinical Immunology (BSACI) Standards of Care Committee (SOCC) identified a need to develop a guideline for the diagnosis and management of PFS in the United Kingdom (UK). Guidelines produced by the BSACI use either the GRADE or SIGN methodology; due to a lack of high‐quality evidence these recommendations were formulated using the SIGN guidelines, which is acknowledged to be less robust than the GRADE approach. The correct diagnosis of PFS ensures the avoidance of a misdiagnosis of a primary peanut or tree nut allergy or confusion with another plant food allergy to non‐specific lipid transfer proteins. The characteristic foods involved, and rapid‐onset oropharyngeal symptoms, mean PFS can often be diagnosed from the clinical history alone. However, reactions involving tree nuts, peanuts and soya milk or severe/atypical reactions to fruits and vegetables may require additional diagnostic tests. Management is through the exclusion of known trigger foods, which may appear to be simple, but is highly problematic if coupled with a pre‐existing food allergy or for individuals following a vegetarian/vegan diet. Immunotherapy to pollens is not an effective treatment for PFS, and although oral or sublingual immunotherapy to foods seems more promising, large, controlled studies are needed. The typically mild symptoms of PFS can lead to an erroneous perception that this condition is always easily managed, but severe reactions can occur, and anxiety about the onset of symptoms to new foods can have a profound effect on quality of life.
