目的:探讨检测肺炎支原体(MP-IgM)、C反应蛋白(CRP)同时测定在诊断小儿呼吸道感染中的价值;方法:对呼吸道感染患儿共1125例,运用间接凝集法检测血清MP-IgM。将其中肺炎支原体感染患儿(阳性组)314例,非支原体感染对照组(阴性组)314例,运用美国贝克曼IMMAGE特定蛋白仪测定C反应蛋白(CRP)值。结果:1125份小儿呼吸道感染血清,314份MP-IgM阳性,阳性率为27.91%。肺炎支原体感染者CRP阳性率明显低于非肺炎支原体感染者。结论:肺炎支原体IgM及C-反应蛋白同时测定可作为小儿MP急性期感染的主要诊断指标。
Objective: To explore the value of simultaneous detection of Mycoplasma pneumoniae (MP-IgM) and C-reactive protein (CRP) in the diagnosis of respiratory tract infection in children.Methods: A total of 1125 children with respiratory tract infection were enrolled in this study. Serum MP-IgM was detected by indirect agglutination. A total of 314 children with mycoplasma pneumoniae infection (positive group) and 314 non-mycoplasma infection (negative group) children were included in the study. The C-reactive protein (CRP) value was determined by Beckman IMMAGE specific protein analyzer. Results: The positive rate of 1125 serogroups of respiratory tract infection in children was 314 positive for MP-IgM, and the positive rate was 27.91%. Mycoplasma pneumoniae infection CRP positive rate was significantly lower than non-Mycoplasma pneumoniae infection. Conclusion: Simultaneous determination of Mycoplasma pneumoniae IgM and C-reactive protein can be used as a major diagnostic indicator of acute MP infection in children.
