摘要: 目的 探讨脓毒症患者血清降钙素原(PCT)、T淋巴细胞亚群、中性粒细胞CD64百分比、危重症评分等指标对病情评估及预后判断价值。方法 检测入院后24小时内、第7天血清PCT、T淋巴细胞亚群、中性粒细胞CD64百分比等指标,计算急性生理学与慢性健康状况评分系统Ⅱ(APACHE Ⅱ)和序贯器官衰竭评分(SOFA)。分析上述指标与病情严重程度的关联性以及对预后判断价值。结果 ①共纳入72例脓毒症患者,总病死率为31.9%。28天病死率脓毒症组为19.57%;脓毒症休克组为53.85%,差异有统计学意义(P<0.05);②脓毒症休克组入院24小时内血清PCT、CD64(%)、APACHE Ⅱ及SOFA评分均高于脓毒症组,T淋巴细胞亚群CD4+/CD8+比值低于脓毒症组(P<0.05);③死亡组入院7天时血清PCT、CD64(%)、APACHE Ⅱ及SOFA评分均高于存活组, T淋巴细胞亚群CD4+/CD8+比值低于存活组(P<0.05)。不同时间点血清PCT与APACHE Ⅱ评分均呈正相关(r分别为0.702, 0.637,P<0.01);不同时间点的T淋巴细胞亚群CD4+/CD8+比值与APACHE Ⅱ评分均呈负相关(r分别为-0.691,-0.659, P<0.01);不同时间点的中性粒细胞CD64百分比与APACHEⅡ评分均呈正相关(r分别为0.676,0.622,P<0.01);不同时间点的SOFA评分与APACHE Ⅱ评分均呈正相关(r分别为0.663,0.762,P<0.01);④血清PCT、T淋巴细胞亚群、中性粒细胞CD64百分比、APACHE Ⅱ评分及SOFA评分均为影响脓毒症预后的独立因素(P<0.05)。以上5项指标对患者28天预后评价能力相当。通过Z检验比较3项检测指标联合和单一指标检测的AUC,差异有统计学意义(P<0.05)。结论 血清PCT、中性粒细胞CD64百分比、T淋巴细胞亚群CD4+/CD8+比值、SOFA评分及APACHE Ⅱ评分可作为判断脓毒症病情严重程度的指标。多项指标联合对预后判断具有更高的敏感性和特异性。

Abstract: Objective  To explore the diagnostic and prognostic  value of serum procalcitonin (PCT),  the level of neutrophil CD64,  the percentage of T lymphocyte subsets,  SOFA score and APACHE Ⅱ score in patients with sepsis.Methods  A  total of  72 patients with sepsis were divided into the sepsis group and the septic shock group. The level of serum PCT,  neutrophil percentage of CD64 and T lymphocyte subsets were measured,  and  APACHE Ⅱ score  and SOFA score (five  indicators) were calculated  at the first day and the seventh day after admission.Logistic regression analysis and the receiver operating characteristic curve were applied to  the  probing of the relationship between those indicators and outcomes.Results  ①Total mortality rate was 31.9%.The mortality rates  of the two group were significantly different,  with that of the sepsis group being  19.57% and septic shock group 53.85% (P=0.019). ②Compared with the  sepsis group,  the four indicators  (namely, PCT,CD65(%), APACHE Ⅱ  and  SOFA)  of the septic shock group  were all higher within the first 24 hour,  but its  ratio of T lymphocyte CD4+/CD8+ were lower than that of the  sepsis group (P<0.05). ③Compared with  the survival group,  the abovementioned  four indicators of the nonsurvival group within the first 24 hour were higher, but  its ratio of T lymphocyte CD4+/CD8+ was  relatively  lower (P<0.05). ④Serum PCT and APACHE score were positively correlated at different time(r=0.702, 0.637,P<0.01) , so were the percentge of CD64 and APACHE Ⅱ (r=0.676, 0.622,P<0.01),  as well as  SOFA  and APACHE Ⅱ(r=0.676, 0.622,P<0.01),   while  the ratio of T lymphocyte CD4+/CD8+  and APACHE score were negatively  related(P<0.01).⑤The five  indicators above  were all independent factors(P<0.05)  affecting  the prognosis of sepsis patients and the more indicators  combined,  the higher sensitivity and specificity.Conclusion  The serum PCT,  the ratio of T lymphocyte CD4+/CD8+,  neutrophil CD64(%),  APACHE Ⅱ score and SOFA score can be used to assess the condition and risk of patients with    sepsis. Combined together,  these factors can have  higher sensitivity and specificity in terms of the prognosis of patients with sepsis.
