BACKGROUND
There is a strong and consistent association between IgE sensitization and allergy, wheeze, eczema and food hypersensitivity. These conditions are also found in non-sensitized humans, and sensitization is found among individuals without allergy-related diseases. The aim of this study was to analyse the sensitization profile in a representative sample of the population, and to relate patterns of allergens and allergen components to allergic symptoms.
METHODS
A population of 195 adolescents took part in this clinical study, which included a self-reported questionnaire and in vitro IgE testing.
RESULTS
Sensitization to airborne allergens was significantly more common than sensitization to food allergens, 43% vs. 14%, respectively. IgE response was significantly higher in airborne allergens among adolescents with rhinitis (p < 0.001) and eczema (p < 0.01). Among 53 children with allergic symptoms according to the questionnaire, 60% were sensitized. Sensitization to food allergens was found among those with rhinitis, but only to PR-10 proteins. None of the participants had IgE to seed storage proteins.
CONCLUSION
The adolescents in this study, taken from a normal Swedish population, were mainly sensitized to grass pollen and rarely to specific food allergens. The major grass pollen allergen Phl p 1 was the main sensitizer, followed by Cyn d 1 and Phl p 2. Sixty-one percent reporting any allergic symptom were sensitized, and the allergen components associated with wheeze and rhinoconjunctivitis were Fel d 4, Der f 2 and Can f 5.
背景
IgE致敏与过敏、喘息、湿疹及食物过敏之间存在强烈且一致的关联。在未致敏的人群中也发现了这些情况,且在无过敏相关疾病的个体中也存在致敏现象。本研究的目的是分析具有代表性的人群样本中的致敏情况,并将过敏原及过敏原成分模式与过敏症状相关联。
方法
195名青少年参与了这项临床研究,其中包括一份自我报告问卷和体外IgE检测。
结果
对空气传播过敏原的致敏显著比食物过敏原致敏更为常见,分别为43%和14%。在患有鼻炎(p < 0.001)和湿疹(p < 0.01)的青少年中,空气传播过敏原的IgE反应显著更高。根据问卷,在53名有过敏症状的儿童中,60%呈致敏状态。在鼻炎患者中发现了对食物过敏原的致敏,但仅针对PR - 10蛋白。没有参与者对种子储存蛋白有IgE反应。
结论
本研究中来自瑞典正常人群的青少年主要对草花粉致敏,很少对特定食物过敏原致敏。主要的草花粉过敏原Phl p 1是主要致敏原,其次是Cyn d 1和Phl p 2。报告有任何过敏症状的人群中有61%呈致敏状态,与喘息和鼻结膜炎相关的过敏原成分是Fel d 4、Der f 2和Can f 5。
