呼吸道感染患者肺炎衣原体感染的研究

CHLAMYDIA PNEUMONIAE INFECTION IN PATIENTS WITH RESPIRATORY TRACT INFECTION

为了解成人呼吸道感染患者肺炎衣原体感染的发病率及临床特征。对呼吸道感染住院患者１１０例，采取静脉血检测肺炎衣原体ＩｇＧ和ＩｇＭ抗体。结果：本组患者肺炎衣原体ＩｇＧ抗体阳性率为７０％；１７例（１５．５％）患者有肺炎衣原体近期感染的急性抗体，其中慢性阻塞性肺疾病所占的比例最高（４１．２％），其次为肺炎（１７．６％）。肺炎衣原体感染的临床表现无特征性。结论：肺炎衣原体是成人呼吸道感染的重要致病原。

A prospective study for Chlamydia pneumoniae (C.pneumoniae) infection was conducted in 110 patients with respiratory tract infection. Serum samples were taken and immunoglobulins G and M (IgG and IgM) fractionsofantibodies to C. pneumoniae were studied by microimmunofluorescence test.The results showed that prevalence of specific IgG was 70% in patients with respiratory tract infection. Seventeen patients (155%) were serologically diagnosed as having recent C.pneumoniae infection and 7 (412%) of these patients were chronic obstructive pulmonary diseases, 3 (176%) were pneumonia.The clinical features between C.pneumoniae infection and nonC. pneumoniae infection showed no significant difference. The data suggested that C.pneumoniae was an important pathogen causing infections of the human respiratory tract.
