尿肺炎链球菌抗原检测对于儿童下呼吸道感染的诊断价值

Diagnostic Value of urinary Streptococcus pneumoniae antigen test for the children of lower respiratory trac infection

目的研究尿肺炎链球菌抗原检测对于儿童下呼吸道感染的诊断价值。方法选择2010年10月至2011年4月我院住院患儿170例,年龄为0-3岁,采用免疫层析法检测肺炎链球菌抗原C-Polysaccharide抗原,联合检测肺炎链球菌抗原、血液分析、超敏C反应蛋白,比较肺炎链球菌抗原检测对于儿童下呼吸道感染的诊断价值。结果 170例患儿中,肺炎链球菌抗原检测阳性率为35.29%,对于明确的侵袭性肺炎链球菌感染其阳性率可达83.33%,治疗前后检测结果有显著性差异。结论采用快速抗原检测技术准确检测感染患儿尿中的肺炎球菌抗原,有助于临床医生辅助诊断链球菌感染,对高危患儿的诊断有较高的价值。

Objective To study the diagnostic value of urinary Streptococcus pneumoniae antigen test for the children of lower respiratory tract infection.Methods 170 cases of children selected from October 2011 to April 2012 in our hospital aged 0-3 years old.The immunochromatography assay for detection of Streptococcus pneumoniae antigen C-Polysaccharide antigens.Joint detection of Streptococcus pneumoniae antigens,blood analysis,high sensitivity C-reactive protein and comparative the diagnostic value of urinary Streptococcus pneumoniae antigen test for the children of lower respiratory tract infection.Results Urinary Streptococcus pneumoniae antigen test positive rate was 35.29% of 170 cases of children,of clear invasive Streptococcus pneumonia infection positive rate up to 83.33%.There are significant differences in the test results before and after treatment.Conclusion Rapid antigen detection technologies to accurately detect infection in the urinary pneumococcal antigen can help clinicians in the diagnosis of streptococcal infection and in the diagnosis of high-risk children have a higher value.
