In Central Europe, hazel (Corylus sp.) pollen is considered to be an important aeroallergen in early spring.
This study examines hazel pollen levels in Poznań, western Poland, and the clinical relevance of this aeroallergen in the city.
Corylus pollen data (1996-2010) were obtained by volumetric spore trap located near the centre of Poznań. Clinical data (2006-2010), i.e. skin prick test (SPT) and allergen-specific IgE measurements (asIgE), were supplied by the Allergy Diseases Diagnostic Centre in Poznań.
Mean diurnal hazel pollen concentrations peaked around 14:00-16:00 when mean bi-hourly pollen concentrations were ~60 P m(-3). Onset of the hazel pollen season varied up to 87 days annually, and was significantly (r=-0.647; p<0.01) related to mean maximum temperature during late December. SPT data revealed that ~11% of allergy patients had positive skin reactions to Corylus pollen allergens, and most of these (94.4%) reacted to pollen allergens from other members of the Betulaceae family - alder or birch. Of those sensitized, 53% suffered from atopic dermatitis. Of patients examined for serum asIgE, 26.0% had asIgE measurements in classes 5 and 6.
Hazel pollen has a detrimental effect on the allergic population of Poznań, with more than half of those sensitised to hazel pollen allergens showing symptoms of atopic dermatitis. Hazel pollen concentrations reach levels recognized as being able to induce allergy symptoms, especially in the afternoon and early evening when many people are returning home from work. The cross-reactivity with other members of the Fagales order also increases the allergenic potential of hazel pollen.
在中欧，榛树（榛属）花粉被认为是早春时节一种重要的空气过敏原。
本研究调查了波兰西部波兹南的榛树花粉水平以及该空气过敏原在该市的临床相关性。
通过位于波兹南市中心附近的容积式孢子捕捉器获取1996 - 2010年的榛树花粉数据。临床数据（2006 - 2010年），即皮肤点刺试验（SPT）和过敏原特异性IgE测量值（asIgE），由波兹南过敏疾病诊断中心提供。
榛树花粉的日平均浓度在14:00 - 16:00左右达到峰值，此时每两小时的平均花粉浓度约为60个/立方米。榛树花粉季节的开始每年变化多达87天，并且与12月下旬的平均最高温度显著相关（r = -0.647；p < 0.01）。皮肤点刺试验数据显示，约11%的过敏患者对榛树花粉过敏原出现阳性皮肤反应，其中大多数（94.4%）对桦木科其他成员——桤木或桦树的花粉过敏原也有反应。在那些致敏的患者中，53%患有特应性皮炎。在检测血清asIgE的患者中，26.0%的患者asIgE测量值处于5级和6级。
榛树花粉对波兹南的过敏人群有不利影响，超过一半对榛树花粉过敏原致敏的人表现出特应性皮炎症状。榛树花粉浓度达到了被认为能够引发过敏症状的水平，尤其是在下午和傍晚时分，此时许多人正下班回家。与壳斗目其他成员的交叉反应也增加了榛树花粉的致敏潜力。
