目的探讨老年人肺炎衣原体感染的临床特点。方法用微量免疫荧光法测定 44例年龄在 6 0岁以上的老年人肺炎衣原体 Ig G抗体 ,并与非肺炎衣原体感染者比较。结果肺炎衣原体 Ig G抗体阳性者 2 1例 ,占 47.7% ;下呼吸道感染占 85 .7% ,上呼吸道感染占14 .3%。临床表现多见发热、轻度咳嗽、喘息等。伴有血脂增高者明显多于非肺炎衣原体感染组 ( P>0 .0 5 ) ;主要为甘油三酯增高 ;心电图检查异常者明显多于非肺炎衣原体感染组 ( P>0 .0 5 )。肺部 X线异常占 6 7% ,其中约 42 .9%伴有胸膜受累。结论肺炎衣原体感染不仅可引起呼吸道感染 ,还与心血管疾病 (主要是冠状动脉病变 )相关 ;但临床表现轻、预后好 ;治疗以大环内酯类抗生素最有效
Objective To investigate the clinical features of Chlamydia pneumoniae infection in the elderly. Methods The quantity of IgG antibodies against Chlamydia pneumoniae in 44 elderly people aged over 60 years was measured by micro-immunofluorescence and compared with non-Chlamydia pneumoniae patients. Results 21 cases were positive for Chlamydia pneumoniae IgG antibody, accounting for 47.7%, 85.7% for lower respiratory tract infection and 14.3% for upper respiratory tract infection. More common clinical manifestations of fever, mild cough, wheezing and so on. Chlamydia pneumoniae infection group was significantly higher than that of non-Chlamydia pneumoniae infection group (P> 0.05), mainly due to the increase of triglyceride, abnormal electrocardiogram examination more than non-Chlamydia pneumoniae infection group (P> 0.05). Lung X-ray abnormalities accounted for 67%, of which about 42.9% with pleural involvement. Conclusion Chlamydia pneumoniae infection can not only cause respiratory tract infection, but also with cardiovascular disease (mainly coronary artery disease), but the clinical manifestations of light, the prognosis is good; the treatment of macrolide antibiotics is the most effective
