目的 探究血清降钙素原(PCT)联合阴离子隙(AG)检测在脓毒症患者预后中预测价值。方法 选取2019年1月—2021年1月于我院治疗117例毒症患者作为研究对象,根据入院治疗28 d的预后情况,分为存活组(78例)和死亡组(39例),对比2组患者一般资料,采用多因素分析其高危因素,应用ROC曲线确定曲线下面积,评估血清PCT联合AG检测对该类患者预后的预测价值。结果 2组患者一般资料对比,年龄、中性粒细胞计数、血清C反应蛋白(CRP)、PCT、AG、APACHEⅡ评分差异有统计学意义(P<0.05);年龄、CRP、PCT、AG水平是该类死亡的危险因素;ROC曲线分析结果显示,血清PCT曲线下面积为0.737,最佳截断值为9.595;AG曲线下面积为0.791,最佳截断值为21.695;血清PCT联合AG检测曲线下面积为0.933,最佳截断值为1.3442。结论 血清PCT联合AG检测对脓毒症患者预后具有较高的预测价值。

Objective To investigate the predictive value of serum procalcitonin (PCT) combined with anion gap (AG) detection on the prognosis of patients with sepsis. Methods One hundred and seventeen patients with sepsis treated in our hospital from January 2019 to January 2021 were selected as study subjects and divided into survival group (78 patients) and death group (39 patients) according to their prognosis at 28 d of admission. The general data of the two groups was compared, multi-factor Logistic analysis of high-risk factors of sepsis patients was performed, area under the ROC curve was applied to assess the predictive value of serum PCT combined AG detection on the prognosis of sepsis patients. Results After comparing the general data of the two groups, the differences in age, neutrophil count, C-reactive protein (CRP), PCT, AG and APACHE II scores were statistically significant (P<0.05); multi-factor Logistic regression analysis showed that age, CRP, PCT and AG levels were risk factors for death in sepsis patients; the results of ROC curve analysis showed that the area under the curve of serum PCT was 0.737, with an optimal cut-off value of 9.595; the area under the AG curve was 0.791, with an optimal cut-off value of 21.695;the area under the curve of serum PCT combined with AG was 0.933, and the optimal cut-off value was 1.3442. Conclusions Serum PCT combined with AG assay had a high predictive value for the prognosis of patients with sepsis.

目的 研究喘憋性肺炎合并脓毒症患儿血清降钙素原(PCT)、C反应蛋白(CRP)水平的临床意义。方法 回顾性分析本院80例喘憋性肺炎患儿临床资料,根据是否合并脓毒症将80例患儿分为观察组(合并脓毒症,38例)和对照组(未合并脓毒症,42例)。比较两组患儿血清PCT、CRP水平,根据脓毒症严重程度将观察组患儿分为脓毒症组(14例)、严重脓毒症组(13例)及脓毒症休克组(11例),比较三组患儿血清PCT、CRP水平,记录患儿2周死亡率。分析血清PCT和CRP诊断喘憋性肺炎合并脓毒症患儿的准确性,探讨其判断预后的价值。结果 观察组患儿血清CRP和PCT水平高于对照组,差异均有统计学意义(P<0.05)。脓毒症休克组患儿血清CRP、PCT水平高于脓毒症组和严重脓毒症组,差异有有统计学意义(P<0.05)。严重脓毒症组患儿血清CRP和PCT均高于脓毒症组,差异有统计学意义(P<0.05)。80例患儿中死亡7例,死亡率8.75%,血清CRP与PCT早期诊断喘憋性肺炎患儿合并脓毒症的AUC分别为0.729和0.743(95%CL=0.617~0.841,0.637~0.849,P均<0.001),联合诊断的AUC分别为0.876(95%CL=0.792~0.960,P<0.001)。血清CRP和PCT判断患儿预后的AUC分别为0.794和0.813(95%CL =0.584~1.000,0.000~1.000,P =0.012,0.007),联合检测判断患儿预后的AUC为0.832(95%CL=0.638~1.000,P<0.001)。结论 喘憋性肺炎合并脓毒症患儿血清CRP和PCT均异常升高,监测血清CRP和PCT有助于脓毒症的早期诊断和患儿预后判断。

目的 探讨慢性阻塞性肺疾病急性期加重期(AECOPD)患者血清降钙素原(PCT)、白介素6(IL-6)、超敏C反应蛋白(hs-CRP)水平变化及与肺功能的相关性。方法 选择121例COPD急性加重期患者为实验组研究对象,选取同期体检的80例稳定期COPD患者为对照组,比较两组患者血清PCT、IL-6、hs-CRP的差别,并对三者与COPD患者肺功能的相关性进行探讨。结果 实验组患者IL-6、hs-CRP水平显著高于对照组(P＜0.05)。实验组FEV1值、FEV1%显著低于对照组(P＜0.05)。Pearson分析显示,实验组hs-CRP与肺功能指标FEV1%呈负相关关系(r=-1.51,P=0.048)。结论 AECOPD患者的血清炎症因子水平明显高于COPD稳定期患者,血清炎症因子与慢阻肺患者肺功能损伤密切相关。
