摘要 目的研究重度脓毒症患者CD14+单核细胞HLA-DR水平及其与预后的相关性。方法选择ICU确诊为重度脓毒症的患者91例,监测患者第1,4,7天外周血CD14+单核细胞HLA-DR表达,记录患者APACHEⅡ评分、Marshall评分和28d预后。结果28d内死亡34例,28d病死率为37.4%。死亡组HLA-DR均明显低于存活组(P<0.001)且持续处于低水平的状态,APACHEⅡ评分和Marshall评分均明显高于存活组(P<0.05,P<0.001);存活组HLA-DR逐渐升高(P<0.01),APACHEⅡ评分和Marshall评分逐渐降低(P<0.001),第7天与第1天比较3项差异均有显著性(P<0.001),且第4天APACHEⅡ评分及Marshall评分与第1天比较差异有显著性(P<0.001)。Spearman相关分析显示,全程HLA-DR与APACHEⅡ评分和Marshall评分均呈负相关(r=-0.237,P=0.000;r=-0.368,P=0.000);在存活组内,全程HLA-DR与呼吸机通气时间和住ICU时间均呈负相关(r=-0.161,P=0.043;r=-0.190,P=0.017)。结论重度脓毒症患者单核细胞HLA-DR水平对患者的预后具有预见性,水平低者病死率高,呼吸机通气时间和住ICU时间长。
