老年人变应性鼻炎变应原检测及相关因素分析

Analysis of Relative Factors of Elder Patients With Allergic Rhinitis Idiotoxin Detection

目的：了解老年人变应性鼻炎的主要变应原及其与气道高反应的关系。方法选取2013年2月～2014年2月在我院耳鼻喉科门诊就诊359例老年变应性鼻炎患者进行分析。结果乙酰甲胆碱气道激发试验阳性率为77%，正常对照组组为16.7%，χ2=28.56，P＜0.0001，差异具有统计学意义。结论老年变应性鼻炎患者气道反应性增加，合并支气管哮喘发病率高，应及早干预并积极治疗老年人变应性鼻炎，减缓和预防哮喘的发生。

Objective To understand the relationship between the idiotoxin and airway hyperresponsiveness in elderly patients. Methods Selected 359 cases with allergic rhinitis from February 2013 to February 2014 in our hospital were analysis. Results Methacholine air passage provocation test positive rate was 77%, the normal control group was 16.7%,χ2=28.56, P〈0.0001,had difference statistically significance. Conclusion Elderly patients with allergic rhinitis increased airway reactivity, combine with bronchial asthma of high morbidity, early intervention and actively to treat the elderly allergic rhinitis to retard and prevent the occurred of asthma.
