摘要:

目的 探讨白细胞群落参数(CPD)对脓毒血症的诊断价值。方法 选取2022年1月—2022年5月同济大学附属上海市东方医院44例脓毒血症患者(脓毒血症组)、27例肺炎患者(肺炎组)、20名健康体检者(健康对照组)。检测所有研究对象CPD、C反应蛋白(CRP)、降钙素原(PCT),建立诊断模型。比较各组各项指标差异;采用受试者工作特征(ROC)曲线评价各项指标诊断脓毒血症的效能。另选取2022年6月—2023年1月同济大学附属上海市东方医院脓毒血症患者70例,进行交叉验证。结果 脓毒血症组中性粒细胞荧光强度(NE-SFL)、中性粒细胞荧光强度分布宽度(NE-WY)、单核细胞细胞复杂程度(MO-X)分别为50.40(46.65,55.20)、717.5(642.3,832.5)、123.4(120.9,125.7),均显著高于健康对照组[43.60(43.03,46.88)、579.0(558.5,595.8)、119.7(118.6,121.0),P<0.05]和肺炎组[46.45(44.73,49.00)、616.5(589.8,634.5)、120.8(119.3,122.7),P<0.05]。NE-SFL、NE-WY、MO-X、CRP、PCT诊断脓毒血症的曲线下面积分别为0.734、0.841、0.727、0.817、0.862;敏感性分别为61.9%、77.4%、44.0%、87.8%、88.6%;特异性分别为80.0%、84.0%、92.0%、69.4%、71.4%。交叉验证结果显示,NE-SFL、NE-WY、MO-X、CRP、PCT的真阳性率分别为71.83%、91.55%、47.89%、73.02%、82.61%;假阴性率分别为28.17%、8.45%、52.11%、26.98%、17.39%。确诊前5 d NE-WY的阳性率明显高于PCT和CRP,NE-SFL、MO-X的阳性率低于PCT、CRP。血培养报阳时间较NE-SFL、NE-WY、MO-X、CRP、PCT滞后。结论 CPD、CRP、PCT在脓毒血症的诊断中有较高的预测价值;NE-WY的诊断效能优于PCT,NE-SFL的诊断效能接近于CRP;NE-WY与PCT联合诊断脓毒血症效能更优。

Abstract:

Objective To investigate the diagnostic value of white blood cell population data (CPD)in patients with sepsis. Methods Totally,44 sepsis patients admitted to Shanghai East Hospital of Tongji University School of Medicine from January 2022 to May 2022 were enrolled,and 27 patients with pulmonary infection,and 20 healthy subjects were enrolled as well. CPD,C-reactive protein(CRP)and procalcitonin(PCT)were determined and analyzed to establish diagnostic model. Receiver operating characteristic(ROC)curve was used to evaluate the efficiency for the diagnosis of sepsis. A total of 70 sepsis patients from June 2022 to January 2023 at Shanghai East Hospital of Tongji University were enrolled for cross validation. Results In sepsis group,neutrophil fluorescence intensity(NE-SFL),width of dispersion of neutrophil fluorescence(NE-WY) and monocyte complexity(MO-X)were 50.40(46.65,55.20),717.5(642.3,832.5),123.4(120.9,125.7),respectively,which were higher than those in healthy control group [43.60(43.03,46.88),579.0(558.5,595.8),119.7(118.6,121.0)](P<0.05) and those in pulmonary infection group [46.45(44.73,49.00),616.5(589.8,634.5),120.8(119.3,122.7)](P<0.05). The areas under curves of NE-SFL,NE-WY,MO-X,CRP and PCT were 0.734,0.841,0.727,0.817 and 0.862,respectively. The sensitivities of NE-SFL,NE-WY,MO-X,CRP and PCT were 61.9%,77.4%,44.0%,87.8% and 88.6%,respectively. The specificities were 80.0%,84.0%,92.0%,69.4% and 71.4%,respectively. The cross validation results showed that the true positive rates of NE-SFL,NE-WY,MO-X,CRP and PCT were 71.83%,91.55%,47.89%,73.02% and 82.61%,respectively. The false negative rates were 28.17%,8.45%,52.11%,26.98% and 17.39%,respectively. The positive rate of NE-WY before diagnosis for 5 d was higher than those of PCT and CRP,while the positive rates of NE-SFL and MO-X were lower than those of PCT and CRP. The positive time of blood culture was delayed compared to NE-SFL,NE-WY,MO-X,CRP and PCT. Conclusions CPD have certain predictive value in the diagnosis of sepsis. The diagnostic efficacy of NE-WY is superior to that of PCT. The diagnostic efficacy of NE-SFL is similar to that of CRP. The combined diagnosis of sepsis using NE-WY and PCT has better diagnostic efficacy.
