摘要

目的

探讨血浆可溶性尿激酶型纤溶酶原激活物受体(soluble urokinase-type plasminogen activator receptor，suPAR)对严重创伤后多器官功能障碍综合征(multiple organ dysfunction syndrome，MODS)的预测价值。

方法

纳入2019年12月至2020年12月我院创伤中心收治的108例严重创伤患者，入院采集静脉血并利用ELISA法检测血浆suPAR浓度，同时收集人口学资料及临床数据，根据住院14 d内的序贯器官衰竭评分(sequential organ failure assessment

SOFA)将患者分为MODS组和非MODS组。比较两组一般资料及suPAR、白细胞计数(WBC)、损伤严重度评分(injury severity score

ISS)等指标，采用Logistic回归分析筛选创伤后MODS的独立预测因素，ROC曲线评估各指标的预测价值。

结果

MODS组患者的年龄、合并慢性疾病率、ISS、入院suPAR、合并休克率、并发感染率和接受手术率均显著高于非MODS组[(52.6±14.1)岁

0.05)，取截断值26分时对应的敏感度为73.5%，特异度为58.1%。

结论

严重创伤患者入院血浆suPAR水平能够预测创伤后MODS的发生，早期监测suPAR对识别患者机体炎症及免疫激活水平、指导临床评估和治疗具有一定价值。

Abstract

Objective

To investigate the predictive value of plasma soluble urokinase-type plasminogen activator receptor (suPAR) for post-severe traumatic multiple organ dysfunction syndrome (MODS).

Methods

A total of 108 patients suffering from severe trauma admitted to the Trauma Center of our hospital from December 2019 to December 2020 were enrolled. Venous blood samples were collected at admission and plasma suPAR concentration was measured by ELISA

and their demographic and clinical data were collected. The patients were divided into MODS group and non-MODS group according to the sequential organ failure assessment(SOFA) within 14 d after admission. The general data and variables such as suPAR

white blood cell (WBC) count

and injury severity score (ISS) were compared between the 2 groups. Logistic regression analysis was used to screen the independent predictors for post-traumatic MODS

and receiver operating characteristic (ROC) curve was adopted to evaluate the predictive value of the variables.

and rate of blood purification between the 2 groups. Multivariate Logistic regression analysis showed that comorbidity

and infection were independent predictors for post-traumatic MODS (

0.05). ROC curve analysis indicated that the area under the curve (AUC) of suPAR for predicting post-traumatic MODS was 0.704 (

0.05). When the cutoff value was 5.04 ng/mL

the sensitivity was 73.5% and the specificity was 62.2%. The AUC of ISS was 0.632 (

0.05)

and the sensitivity was 73.5% and the specificity was 58.1% when the cutoff value was 26.

Conclusion

The plasma suPAR level at admission can predict the occurrence of post-traumatic MODS in patients with severe trauma. Early monitoring of suPAR has a certain value in evaluation of inflammation and immune activation in the body and in guidance of clinical evaluation and treatment.
