Simultaneously, skin prick tests (SPTs) were performed on children with respiratory allergic conditions at the Children’s Hospital of Soochow University and standardised questionnaires are also administered to assess children’s symptoms.Results: Over the course of November 2020 to October 2021, the study identified more than 36 pollen species. Notably, the spring season (March to May) exhibited the highest pollen concentrations, with Broussonetia accounting for 30.04% and Pinus for 26.38%. Similarly, the autumn months (September to October) saw prominent taxa like Humulus scandens (47.55%) and Gramineae (35.93%). Among the patients, a significant 92.7% exhibited positive reactions, with 81.7% showing sensitization to house dust mites (HMD), 17.8% to pollen, and 3.7% to Cockroach. Noteworthy the five most common pollens were observed for Bermuda (6.0%), Elm pollen (6.0%), Birch pollen (4.6%), and Mugwort (4.6%). The study indicated a substantial multisensitized ratio among pollen-sensitized patients in comparison to non-pollen-sensitized ones (97.4% vs 1.6%, P < 0.001). Moreover, weekly total airborne pollen concentrations showed positive correlations with weekly admissions due to allergic rhinitis(AR)(r=0.642, P < 0.001), bronchial asthma (BA) (r= 0.472, P< 0.001), and the coexistence of AR and BA (r=0.485, P < 0.001).Conclusion: The findings found that there were two peaks of pollen count in a year during March-May and September-October. The findings emphasize the critical role of specific airborne pollens in driving sensitization and exacerbating respiratory allergic diseases in children.Keywords: pollen, respiratory allergic diseases, China |
