特应性指“遇共同抗原产生IgE抗体的倾向”,尤其是哮喘和枯草热的一个主要危险因素。通常认为嗜酸细胞增多、血清IgE水平增高和皮肤过敏反应这三种显型标志适用于鉴定相同基础的“特应性”状态,但最近流行病学调查提示不同种类呼吸道症状可能与独特的标志显型有关。为了使这些概念更完整,对中老年人群中呼吸道症状与这三种显型标志的关系进行分析。
Atopy refers to “propensity to produce IgE antibodies against common antigens,” especially one of the major risk factors for asthma and hay fever. Three phenotypic markers, such as increased eosinophilia, elevated serum IgE levels, and anaphylactic reactions to the skin, are generally considered appropriate for the identification of the same underlying “atopic” status, but recent epidemiological studies suggest that different types of respiratory symptoms may be associated with unique markers Significantly related. In order to make these concepts more complete, the relationship between respiratory symptoms and these three phenotypic markers in the middle-aged and elderly population was analyzed.
