摘要: 摘要: 目的 探讨外周血CD64指数、白细胞(WBC)计数在小儿败血症早期诊断、预后监测中的价值。 方法 选取小儿败血症患儿57例、一般感染肺炎患儿65例、健康对照者36名,应用流式细胞术检测CD64指数,血液分析仪检测WBC。 结果 CD64指数、WBC计数在败血症组、肺炎组和健康对照组之间差异有统计学意义(P<0.01);血培养阳性者CD64指数高于血培养阴性者(P<0.05);根据受试者工作特征(ROC)曲线,当CD64指数临界值取2.25时,敏感性为88%,特异性为85%;经治疗后CD64指数明显下降(P<0.01),但未降至正常水平,与对照组比较差异仍有统计学意义(P<0.01)。 结论 CD64指数具有最佳的临床诊断价值,可以指导临床早期诊断和鉴别诊断小儿败血症,并可作为预后判断的指标。

Abstract: Objective To investigate the significance of peripheral blood CD64 index and white blood cell (WBC )for the early diagnosis and prognosis monitoring of sepsis in children. Methods A total of 57 children with sepsis, 65 children with pneumonia and 36 healthy children were enrolled. The index of CD64 was determined by flow cytometry, and WBC was determined by haematology analyzer. Results The index of CD64 and WBC in sepsis, pneumonia and healthy control groups had statistical significance (P<0.01). The index of CD64 in the blood culture positive was significantly higher than that in the blood culture negative (P<0.05). According to the receiver operating characteristic(ROC)curve, when the cut-off value in the diagnosis of sepsis was 2.25, the sensitivity was 88%, and the specificity was 85%. After treatment, the index of CD64 decreased significantly (P<0.01), but not to be the normal level, and the difference was statistically significant compared with the healthy control group (P<0.01).  Conclusions The index of CD64 has the clinical significance for the early diagnosis and prognosis of sepsis in children.
