目的 :探讨肺炎衣原体感染率与呼吸系统疾病的关系。方法 :选择急性呼吸系统感染 ,慢性支气管炎急性发作 ,支气管哮喘病人为研究对象 ,采用聚合酶链反应 (PCR)进行检测。结果 :3组病人和健康人PCR阳性率分别为 44 %、6 8%、33%、2 8%。其中慢性支气管炎急性发作病人阳性率与健康人的差别有显著性 (P <0 0 1)。对于哮喘病人 ,PCR阳性者血IgE比阴性者显著增高 (P <0 0 1)。结论 :肺炎衣原体感染相当普遍 ,其感染可能是慢性支气管炎急性发作或慢性支气管炎发生、发展中的一个病因
Objective: To investigate the relationship between the infection rate of Chlamydia pneumoniae and respiratory diseases. Methods: Acute respiratory infections, acute exacerbation of chronic bronchitis and bronchial asthma were selected as the research objects and detected by polymerase chain reaction (PCR). Results: The positive rate of PCR was 44%, 68%, 33% and 28% respectively in 3 groups of patients and healthy people. The positive rate of chronic bronchitis in patients with acute exacerbation and healthy people was significant (P <0.01). For asthmatic patients, PCR-positive IgE was significantly higher than negative (P <0.01). Conclusions: Chlamydia pneumoniae infection is quite common and its infection may be an etiology of chronic bronchitis or chronic bronchitis
