目的分析新乡市儿童肺炎支原体(MP)、肺炎衣原体(CPn)感染情况。方法选取符合肺炎诊断标准的308例患儿,应用胶体金法行血MP-IgG、CPn-IgG、MP-IgM及CPn-IgM抗体检测,并对所有病例的临床资料进行统计学分析。结果 308例肺炎患儿中检出MP、CPn阳性病例80例(其中混合感染9例);婴儿组与儿童组、幼儿组与儿童组感染率比较差异均有统计学意义(χ2=13.40,P<0.05;χ2=8.71,P<0.05)。MP感染70例,感染率为22.73%,各年龄组间MP感染率比较差异无统计学意义(χ2=1.67,P>0.05);CPn感染19例,阳性率为6.16%,各年龄组间CPn感染率比较差异无统计学意义(χ2=0.12,P>0.05)。结论 MP、CPn是新乡市小儿肺炎感染的重要病原体,存在混合感染的现象,应重视MP、CPn的实验室依据,早期合理诊治。
Objective To analyze the prevalence of Mycoplasma pneumoniae (MP) and Chlamydia pneumoniae (CPn) in children in Xinxiang City. Methods Thirty-eight children with pneumonia were selected. The blood samples of MP-IgG, CPn-IgG, MP-IgM and CPn-IgM were detected by colloidal gold method. The clinical data of all the cases were analyzed statistically. Results Among the 308 children with pneumonia, 80 cases were detected positive for MP and CPn (9 cases were mixed infection). There was significant difference in the infection rates between infants and children, children and children (χ2 = 13.40, P <0.05; χ2 = 8.71, P <0.05). MP infection in 70 cases, the infection rate was 22.73%, there was no significant difference in MP infection rate between different age groups (χ2 = 1.67, P> 0.05); CPn infection in 19 cases, the positive rate was 6.16% The infection rate was no significant difference (χ2 = 0.12, P> 0.05). Conclusions MP and CPn are important pathogens of pneumonia in children with pneumonia in Xinxiang City. There is a mixed infection phenomenon. MP and CPn should be paid attention to on laboratory basis and should be diagnosed and treated early.
