“…Consistent with other studies [17, 18], we found no associations between plant allergies and asthma morbidity, except that those with a plant-based allergy were more likely to receive specialist care for asthma. Pet allergies were also common: however, unlike a previous study demonstrating positive associations between pet allergies and asthma severity [19], we found no relationships between pet allergies and asthma morbidity.…”

BackgroundUrban adolescents suffer a disproportionate burden of asthma morbidity, often in association with allergies. Literature is limited on comparing various types of allergies regarding prevalence and associations with asthma morbidity in urban dwelling adolescents. The purpose of this study was to examine the prevalence of common allergies reported by urban adolescents and to assess their relationships to healthcare utilization and asthma control.MethodsStudy participants included 313 urban adolescents (12–20 years of age) with persistent asthma who were recruited from three states in the United States. Self-report data were collected on nine indoor and outdoor allergies, healthcare utilization, and asthma exacerbation. Logistic regressions and zero-inflated Poisson regressions were conducted to examine the relationships between allergies and asthma morbidity.ResultsThe mean age of participants was 14.58 (± 1.97) and 52% were female, and 79% were black. Seventy-three percent (n = 229) reported one or more allergies. Dust mite and grass allergies were most common, each reported by 50%. The prevalence of pest allergies (cockroach and mouse) was 27.5% and 19%, respectively. Those with pest allergies were more likely to report ED visits (cockroach- Odds Ratio (OR) = 2.16, 95% CI 1.18–3.94, p = .01; mouse- OR = 2.13, 95% CI 1.09–4.07, p = .02), specialist visits (cockroach-OR = 2.69, 95% CI 1.60–4.54, p < .001; mouse- OR = 2.06, 95% CI 1.15–3.68, p = .01) and asthma exacerbation (cockroach-OR = 2.17, 95% CI 1.26–3.74, p < .001; mouse- OR = 2.30, 95% CI 1.26–4.18, p = .01). Cockroach allergies were associated with 2.2 times as many nights in the hospital (95% CI 1.053–3.398, p = 0.036) and 2.2 times as many specialist visits (95% CI 1.489–3.110, p < 0.001), and mouse allergy was associated with 1.6 times as many ED visits (95% CI 1.092–2.257, p = 0.015) compared to those without pest allergies.ConclusionsConcomitant occurrence of allergies is ubiquitous among urban adolescents with asthma. Only pest allergies, of those examined, appear to have implications for poorly controlled asthma, exacerbation and acute healthcare utilization. To reduce asthma burden in urban adolescents, identification and management of high-risk adolescents with pest allergen sensitization and exposure are warranted.

“…None were statistically significant. The findings of the questionnaire survey are in agreement with an analysis of children within the ISAAC study by Burr et al [14], and of adults within the GERID study by Marchetti et al [15], where the prevalence of allergic rhinitis was inversely associated with pollen exposure.…”

“…The ECAP study showed grass and birch pollen as the sources of the most commonly sensitizing outdoor allergens [5]. While the duration and severity of allergy symptoms in sensitized individuals depend on the pollination intensity of the sensitizing taxon [6][7][8][9][10][11][12][13], the available literature does not unequivocally address the question of association between the degree of exposure to pollen in different geographical regions and the rate of sensitization among the respective populations [14][15][16][17][18][19][20].…”

Introduction: Despite the known role of pollen allergens in causing allergy symptoms in sensitized individuals, there are few publications investigating the relationship between pollen exposure in different regions and the prevalence of inhalant allergy. Aim: To assess the association between the prevalence of allergic rhinitis and asthma and the degree of exposure to pollen in various regions of Poland. Material and methods: Completed questionnaires of 9,443 subjects living in four urban centres (Wroclaw, Katowice, Warsaw, Bialystok), collected within part of the ECAP project, were analyzed. Children aged 6-7 (n = 2 278), adolescents aged 13-14 (n = 2 418), and adults aged 20-44 (n = 4 747) constituted 24.2%, 25.6% and 50.3% of the respondents, respectively. The clinical part (including skin prick tests, an assay of Timothy grass-specific IgE), was attended by 24% of the respondents. Data from 6-year pollen monitoring served to characterize birch and grass pollen seasons. Results: We found insignificant negative associations between the duration of birch pollen season and the prevalence of declared allergic rhinitis and asthma during the season across all age groups. There were insignificant inverse associations between the number of days with above-threshold and high grass pollen concentrations, total grass pollen count and the prevalence of declared allergic rhinitis and asthma during the season across all age groups. Associations noted in the clinical part were also non-significant; however, these trends were not uniform across the age groups. Conclusions: Our findings do not confirm the hypothesis of a positive association between pollen exposure and the prevalence of allergic rhinitis and asthma.

“…Climate is associated with air pollution levels and may also act on the allergens by altering local and regional allergen production or by increasing the allergenicity of pollen (D'Amato et al 2016;Sénéchal et al 2015). Air pollution acts directly on pollen (D'Amato et al 2007), and particles carrying pollen allergen molecules are likely to play a role in the association between air pollution and respiratory allergic diseases (Bono et al 2016;Marchetti et al 2017). Finally, the level of pollen exposure is associated to allergic rhinitis incidence and prevalence and has also been associated to severity of rhinitis (Annesi-Maesano et al 2012).…”
