Abstract

Background

The European Aeroallergen Network (EAN) is a Europe-wide, noncommercial network for the standardized collection and analysis of pollen and fungal spores. It plays a central role in the research and prevention of inhalation allergies, such as the widespread birch pollen allergy. The EAN database facilitates international research, clinical studies, and the provision of daily pollen information by virtue of its extensive, quality-assured, long-term data.

Methods

The EAN database is a Java-based, two-stage web application with TLS-secured data transmission. Authorized users are permitted to upload pollen measurement data, analyze it, and make it available to others within the framework of scientific collaborations. The functionality of the database was examined through the utilization of four distinct application examples, with measurement stations located in three Austrian cities (Graz, Innsbruck, and Vienna) serving as the experimental setting: (1) calculation of base statistics for seasonal characterization, (2) completeness report for quality control, (3) comparison graphics for showing interannual differences, and (4) European maps based on pollen data from several hundred European pollen traps for the spatial visualization of pollen loads.

Results

The EAN data show that the 2025 birch pollen season began about 2 weeks later and was less intense than that of 2024. A decline in total pollen counts and peak concentrations was observed at all measuring stations, indicating a shift between mast and nonmast years. Completeness analyses were conducted to provide information on data quality and to facilitate the identification of missing periods. Comparative graphs illustrated annual and location-dependent differences in exposure, while European maps visualized the seasonal progression and long-range transport of birch pollen.

Conclusion

The results highlight the scientific and practical importance of the EAN database for allergy research, clinical studies, and pollen information services. The system was developed to promote international comparability, quality control, and forecasting. Furthermore, the EAN database is a valuable resource for aerobiological and climate research. The long-term records of aerobiological data reveal trends in flowering times, pollen concentrations, and mast years, as it has been shown for the birch pollen season in the present study. Consequently, these records can serve as biotic indicators of climate change.

欧洲空气过敏原网络(EAN):分析欧洲桦树花粉季节的关键工具
欧洲空气过敏原网络(EAN)是一个全欧洲范围的非商业网络,用于花粉和真菌孢子的标准化收集和分析。它在研究和预防吸入性过敏中起着核心作用,例如广泛的桦树花粉过敏。EAN数据库凭借其广泛、有质量保证的长期数据,促进了国际研究、临床研究和每日花粉信息的提供。EAN数据库是基于java的两阶段web应用程序,数据传输采用tls安全协议。授权用户可以上传花粉测量数据,对其进行分析,并在科学合作框架内将其提供给其他人。通过使用四个不同的应用实例来检查数据库的功能,位于三个奥地利城市(格拉茨、因斯布鲁克和维也纳)的测量站作为实验设置:(1)季节特征的基础统计计算;(2)质量控制的完备性报告;(3)显示年际差异的比较图;(4)基于数百个欧洲花粉捕获器花粉数据的欧洲图,用于花粉负荷的空间可视化。结果2025年白桦花粉季开始时间比2024年晚约2周,花粉季强度较2024年弱。所有测点的花粉总数和峰值浓度均呈下降趋势,表明在柱状年和非柱状年之间发生了变化。进行了完整性分析,以提供有关数据质量的信息,并便于查明缺失的时期。对比图说明了暴露的年度和地点依赖差异,而欧洲地图可视化了桦树花粉的季节性进展和远距离运输。结论EAN数据库在变态反应研究、临床研究和花粉信息服务中具有重要的科学意义和实用价值。该系统的开发是为了促进国际可比性、质量控制和预测。此外,EAN数据库是一个宝贵的资源,为空气生物学和气候研究。空气生物学数据的长期记录揭示了开花时间、花粉浓度和杆年的趋势,正如本研究中所显示的桦树花粉季节。因此,这些记录可以作为气候变化的生物指标。

期刊介绍: Allergo Journal International is the official Journal of the German Society for Applied Allergology (AeDA) and the Austrian Society for Allergology and Immunology (ÖGAI). The journal is a forum for the communication and exchange of ideas concerning the various aspects of allergy (including related fields such as clinical immunology and environmental medicine) and promotes German allergy research in an international context. The aim of Allergo Journal International is to provide state of the art information for all medical and scientific disciplines that deal with allergic, immunological and environmental diseases. Allergo Journal International publishes original articles, reviews, short communications, case reports, and letters to the editor. The articles cover topics such as allergic, immunological and environmental diseases, the latest developments in diagnosis and therapy as well as current research work concerning antigens and allergens and aspects related to occupational and environmental medicine. In addition, it publishes clinical guidelines and position papers approved by expert panels of the German, Austrian and Swiss Allergy Societies. All submissions are reviewed in single-blind fashion by at least two reviewers. Originally, the journal started as a German journal called Allergo Journal back in 1992. Throughout the years, English articles amounted to a considerable portion in Allergo Journal. This was one of the reasons to extract the scientific content and publish it in a separate journal. Hence, Allergo Journal International was born and now is the international continuation of the original German journal. Nowadays, all original content is published in Allergo Journal International first. Later, selected manuscripts will be translated and published in German and included in Allergo Journal.
