小儿肺炎支原体感染的临床检验特点

目的：总结小儿发生肺炎支原体感染的临床表现以及临床检验特点，提高临床诊断水平。方法对2013年1月～2014年1月收治的156例小儿肺炎支原体感染患者进行临床检验分析，所有患者均接受酶联免疫吸附剂测定（ELISA）肺炎支原体IgM抗体检验（MP-IgM），被动凝集法检验，以及血常规、尿常规、血生化、血气分析、细菌培养等各项常规检查。结果分析和总结临床检验结果，发现MP-IgM检测法和被动凝集法具有较高的特异性，阳性率分别为39.1%和37.2%，二者差异无统计学意义（P＞0.05）。其他各项常规检查缺乏特异性。结论对可疑肺炎支原体感染患儿应进行早期实验室检查并结合影像学及其临床表现进行综合分析，及早确诊，MP-IgM检测法和被动凝集法具有较高的特异性。

The clinical features of the Mycoplasma pneumonia among children

Objective To summery the clinical features of the Mycoplasma pneumoniae（MP）among children, in order to improve diagnosis of the MP. Methods 156 cases diagnosed with MP from Jan 2013 to Jan 2014 were tested for antibody Ig-M, passive agglutination test and other regular clinical tests, including blood routine examination, routine urinalysis, biochemical indexes, blood gas analysis and bacterial culture. Results Antibody IgM and passive agglutination test are both effective way to detect MP. And the positive rates are separately 39.1%and 37.2%, which have no significant difference. Other regular examinations lack enough specificity. Conclusion It has been a problem waiting to be solved urgently that the specific method to diagnose MP is lacked. It has always been difficult to make a definite diagnosis. Therefore, the comprehensive diagnosis should be made earlier for the suspected children based on the analysis combined with imaging and its clinical manifestations to avoid the delay in treatment.
