哮喘患者气道反应性的流行病学分析

６４１个哮喘核心家系的资料分析结果显示，利用乙酰甲胆碱（ＭＴＣＨ）激发试验测定的气道高反应性，做为哮喘诊断标准的灵敏度和特异度分别是７２％、７０％。气道反应阳性者患哮喘的危险性是气道反应阴性者的５．０１倍，其中，男女患哮喘的危险性分别是４．９７倍和５．０６倍，都具有高度显著性意义。患哮喘的危险性随着气道反应性的增强而增大。同一ＭＴＣＨ剂量激发的气道反应阳性者，患哮喘的危险性随着年龄的增加而增加，且有明显的线性趋势（Ｐ＜０．０１）。无论是临床还是预防医学，气道反应性的测定都具有重要意义

Epidemiological study of airway responsiveness on the patients with asthma]

The analysis of date on 641 nuclear families with asthma declared that the sensity and specify of the airway responsiveness with Methecholone(MTCH) Challenge Test for the clinical diagnosis of asthma is 72 percent and 70 percent. The population with airway hyperresponsiveness was 6.01 times higher risk to asthma than one of negative airway responsiveness. The OR of male and female for asthma was 4.97, 5.06, respectively, and was statistically significant (P < 0.01). Moreover, the risk of asthma was been increasing with MTCH concentration was increased (i.e. degree of airway responsiveness decreased) step by step, as well showed the lineage trend between the asthma and airway responsiveness significantly (P < 0.01). The Measurement of airway responsiveness play an important role in clinic and prevent medicine.
