摘要 目的检测新生儿败血症外周血中性粒细胞表面CD64的表达水平,探讨其对新生儿败血症的诊断价值。方法将67例新生儿败血症和27例无感染症状的新生儿进行外周血中性粒细胞CD64、血清C反应蛋白(CRP)和白细胞(WBC)计数检测。结果败血症组外周血中性粒细胞CD64为62.3%±9.3%,非感染组为7.2%±2.3%,两组比较差异有统计学意义(P<0.01)。CRP在败血症组与非感染组之间差异也有统计学意义(P<0.05),而两组之间的WBC则差异无统计学意义(P>0.05)。ROC曲线分析显示,CD64曲线下面积为0.92,CRP曲线下面积为0.73,而WBC曲线下面积仅为0.56。结论新生儿败血症外周血中性粒细胞表面CD64的表达及血清CRP水平均显著增加,可作为早期诊断新生儿败血症的实验室指标,且中性粒细胞表面CD64表达较血清CRP有更高的敏感性和特异性。
