【摘要】 目的:探討降钙素原(PCT)、C反应蛋白(CRP)、白细胞(WBC)、中性粒细胞比率(N%)在脓毒症抗菌治疗中的早期诊断价值和对疾病严重程度的评价。方法:选择2017年1月-2019年12月本院重症医学科(ICU)收治的重症患者152例的临床资料,将患者分为脓毒症总组104例和非脓毒症组(对照组)48例,而脓毒症总组根据疾病严重程度分为脓毒症组(n=62)与脓毒性休克组(n=42),对照组48例均为ICU中未使用抗生素的危重症患者。计算各组入ICU第1天急性生理和慢性健康评分Ⅱ(APACHEⅡ),收集所有患者第1、2、5天及转出或死亡前空腹外周静脉血送检,测定PCT、CRP、WBC、N%,并对相关数据进行统计分析。结果:脓毒性休克组PCT高于脓毒症组,差异有统计学意义(P<0.01);脓毒性休克组死亡率高于脓毒症组,差异有统计学意义(P<0.05)。脓毒症总组第5天PCT、末次WBC水平与对照组比较,差异均无统计学意义(P>0.05);脓毒症总组其余各时间点各指标与对照组比较,差异均有统计学意义(P<0.05)。PCT、CRP、WBC、N%敏感度分别为97.12%、87.50%、89.93%、91.35%,特异度分别为83.33%、56.70%、68.37%、68.75%,其中PCT特异度大于80%。结论:PCT、CRP、WBC和N%对脓毒症均有一定的辅助诊断价值,其中血清PCT水平对脓毒症的早期辅助诊断价值更高,并可帮助判断疾病的严重程度,预测治疗效果。

[Abstract] Objective: To explore the value of combined detection of procalcitonin (PCT), C-reactive protein (CRP), white blood cell (WBC), and neutrophil ratio (N%) in the early diagnosis of sepsis antibacterial therapy and disease severity evaluation. Method: A total of 152 patients with severe illness in ICU of our hospital were selected from January 2017 to December 2019. The patients were divided into sepsis general group 104 cases and non-sepsis group (control group) 48 cases, and the sepsis general group was divided into sepsis group (n=62) and septic shock group (n=42), and the control group consisted of 48 critically ill patients without antibiotics in ICU. Acute physiology and chronic health score Ⅱ (APACHEⅡ) of each group on the first day of ICU admission was calculated, fasting peripheral venous blood were collected on the 1st, 2nd, 5th and before transfer out or death, serum PCT, CRP, WBC and N% were measured, the related data were statistically analyzed. Result: PCT in septic shock group was higher than that in sepsis group (P<0.01). The mortality of septic shock group was higher than that of sepsis group (P<0.05). The levels of PCT on the 5th day and WBC at last time in sepsis general group compared with the control group, there were no significant differences (P>0.05); the indicators at the other time points of sepsis general group compared with the control group, there were significant differences (P<0.05). The sensitivity of PCT, CRP, WBC and N% were 97.12%, 87.50%, 89.93% and 91.35% , and the specificity were 83.33%, 56.70%, 68.37% and 68.75% respectively, the specificity of PCT was more than 80%. Conclusion: PCT, CRP, WBC and N% have certain auxiliary diagnostic value for sepsis, serum PCT level has higher auxiliary diagnostic value for sepsis in early stage, and can help to judge the severity of the disease and predict the treatment effect.

降钙素原(PCT)、C反应蛋白(CRP)、白细胞(WBC)、中性粒细胞比率(N%)是目前临床上常用的血液检验指标,其对脓毒症的诊断及预后具有良好的提示作用[1-3]。如何早期合理选用抗菌药物,感染加重时如何及时更改抗感染治疗方案,而感染控制后如何及时降阶梯治疗,以较少的剂量取得较佳效果的同时减缓病菌耐药的速度及多重耐药细菌的出现,提高生存率,是现今临床抗生素管理急需解决的问题。因此,本研究根据PCT、CRP、WBC和N%检测进一步指导基层重症医学科(ICU)危重患者脓毒症感染的抗菌药物管理,并比较单项检测的效果,旨在为抗菌药物管理方法的改善提供一定的理论依据,这对临床脓毒症菌属的推断及临床经验性用药有一定的指导作用。……
