目的 探讨小儿下呼吸道肺炎衣原体 (CP)感染的临床特点。方法 采用ELISA法测定患儿血清CP抗体 ,并观察阳性者的临床症状、体征、X线表现。结果 儿童期下呼吸道CP感染率为 9.2 % ,儿童组高于婴幼儿组 ,后者发热、肺部湿罗音及胸部X线改变者高于前者。结论 CP是儿童期下呼吸道感染常见病原之一 ,临床以呼吸道非特异性症状为主要表现 ,年龄小者则感染率较低 ,但起病相对较急 ,症状、体征、肺外并发症相对较重
Objective To investigate the clinical features of lower respiratory tract infection of Chlamydia pneumoniae (CP) in children. Methods Serum anti-CP antibody was measured by ELISA and clinical symptoms, signs and X-ray findings were observed. Results The prevalence of CP in children with lower respiratory tract was 9.2% in children and higher in infants than in infants. The latter had fever, wet rales in the lungs and chest X-ray changes were higher than the former. Conclusions CP is one of the common pathogens of lower respiratory tract infection in childhood. Non-specific respiratory symptoms are the main clinical manifestations. In younger age, the infection rate is lower but the onset is relatively acute. The symptoms, signs and extra-pulmonary complications are relatively heavy
