摘要
目的探讨单核细胞人白细胞抗原-DR(human leukocyte antigen DR,HLA-DR)和S100A12在血液肿瘤脓毒血症的诊断和预后的价值及相关危险因素。方法选取ICU住院的血液肿瘤合并脓毒血症患者为脓毒血症组,感染患者为非脓毒血症组,流式细胞仪和ELISA检测HLA-DR和S100A12,将脓毒血症组依结局分为死亡和生存组,分析HLA-DR和S100A12对血液肿瘤合并脓毒血症预后的相关性。结果脓毒血症组APACHEⅡ、死亡率、S100A12、PCT和CRP均高于非脓毒血症组,而HLA-DR则相反;S100A12、PCT、CRP、APACHEⅡ、WBC和HLA-DR均和血液肿瘤脓毒血症预后有关(P <0.05);S100A12和HLADR是血液肿瘤脓毒血症死亡的危险因素;HLA-DR和S100A12联合检测诊断血液肿瘤脓毒血症敏感性高。结论血液肿瘤脓毒血症患者HLA-DR降低和S100A12升高是患者预后的危险因素,联合检测为预后提供价值。
Objective To evaluate monocyte human leukocyte antigen DR(HLA-DR)and serum S100 A12 in diagnosis and prognosis of ematological tumor with sepsis,and to analyze the related risk factors. Methods Patients with hematological tumor with sepsis and without sepsis were enrolled in Qinghai Provincial People′sHospital. The clinical and laboratory characteristics were collected. Levels of HLA-DR and S100 A12 were detectedby flow cytometry and ELISA,respectively. The clinical and laboratory data were analyzed by the independentsample t-test,chi-square test and binary Logistic regression analysis,respectively. According to the outcome ofhematological malignancy with sepsis,patients were divided into death and survival group,the correlation betweenHLA-DR,S100 A12 and prognosis of hematologic malignancies with sepsis was analyzed by Poisson correlationanalysis method. Results APACHEⅡ,mortality,S100 A12,PCT and CRP in sepsis patients were higher thanthose in non-sepsis patients,but HLA-DR was on the contrary. S100 A12,PCT,CRP,APACHEⅡ,WBC andHLA-DR were all associated with the prognosis of hematologic malignancies combined with sepsis. MultivariateLogistic regression analysis showed that S100 A12 and HLADR were risk factors of death in hematological tumorswith sepsis. The combined detection of HLA-DR and S100 A12 in hematologic malignancies of septic patients wasmore sensitive than the single test. Conclusions The low HLA-DR expression and high S100 A12 level are riskfactors for the prognosis of hematologic malignancies with sepsis. Combined detection of the HLA-DR and S100 A12 was valuable for prognosis of hematologic malignancies with sepsis.
