Clinical Diagnosis and Prognostic Value of Serum Syndecan-1 and PTX-3 Levels in Patients with Multiple Organ Dysfunction Syndrome Complicated by Multiple Injuries

目的 探讨多发伤并发多器官功能障碍综合征(multiple organ dysfunction syndrome,MODS)患者血清多配体蛋白聚糖-1(syndecan-1)、正五聚蛋白-3(pentraxin 3,PTX-3)水平检测的临床诊断及预后价值。方法 前瞻性纳入2022年1月~2023年6月唐山中心医院收治的140例多发伤患者作为研究对象,根据有无并发MODS分为MODS组(n=49)和非MODS组(n=91),并根据患者入院28天内的生存情况,将MODS组分成存活组(n=21)和死亡组(n=28)。采用酶联免疫吸附法(ELISA)测定患者血清Syndecan-1和PTX-3表达水平;采用受试者工作特征(ROC)曲线分析血清Syndecan-1和PTX-3对MODS的诊断价值及二者对多发伤并发MODS患者预后预测效能。结果 MODS组多发伤并发MODS患者创伤严重度(injury severity score, ISS)评分(24.41±5.22分)、急性生理与慢性健康评分(acute phyusiology and chronic health evaluation, APACHE)Ⅱ评分(22.02±4.41分)以及血清Syndecan-1(77.76±8.25 ng/ml)和PTX-3表达水平(34.87±4.53 pg/ml)高于非MODS组(18.62±4.06分,16.69±3.54分,63.98±7.52 ng/ml,25.43±3.97pg/ml),差异具有统计学意义(t=7.265,7.783,9.994,12.766,均P<0.05);血清Syndecan-1和PTX-3各自单独诊断多发伤并发MODS的曲线下面积(AUC)分别为0.796,0.867,而二者联合诊断的AUC为0.941,二者联合的诊断价值优于Syndecan-1和PTX-3各自单独诊断(Z=4.029,2.681,P=0.001,0.007),且诊断敏感度显著高于常规炎性指标IL-6,PCT。死亡组患者血清Syndecan-1(85.17±9.03ng/ml)和PTX-3表达水平(40.20±5.21pg/ml)均高于生存组(67.90±7.22 ng/ml,27.77±3.64 pg/ml),差异具有统计学意义(t=7.201,9.345,均P<0.05);血清Syndecan-1和PTX-3各自单独预测多发伤并发MODS患者预后状态的AUC分别为0.845,0.792,而二者联合预测的AUC为0.932,二者联合优于Syndecan-1和PTX-3各自单独预测(Z=1.982, 2.311,P=0.047,0.020),对多发伤并发MODS患者预后状态具有一定的预测价值。结论 血清Syndecan-1和PTX-3表达水平与多发伤并发MODS的发生有关,二者联合检测对多发伤并发MODS具有较高的诊断及预后价值。

Objective To explore the clinical diagnostic and prognostic value of serum levels of Syndecan-1 and pentraxin 3(PTX-3)in patients with multiple organ dysfunction syndrome(MODS)complicated by multiple injuries.Methods A sum of 140 patients with multiple injuries admitted to Tangshan Central Hospital from January 2022 to June 2023 were collected prospectively as the research subjects,and they were divided into MODS group(n=49)and non MODS group(n=91)based on the presence or absence of concurrent MODS.According to the survival status of the patients within 28 days of admission,the MODS group was grouped into a survival group(n=21)and a death group(n=28).Enzyme linked immunosorbent assay(ELISA)was applied to measure the expression levels of Syndecan-1 and PTX-3 in serum and the diagnostic value of serum Syndecan-1 and PTX-3 in MODS and their predictive efficacy in predicting the prognosis of patients with multiple injuries combined with MODS were analyzed using the receiver operating characteristic(ROC)curve analysis.Results The ISS score,acuse physiology and chronic health evaluation(APACHE)II score,and serum Syndecan-1 and PTX-3 expression levels in the MODS group(24.41±5.22 scores,22.02±4.41 scores,77.76±8.25 ng/ml,34.87±4.53 pg/ml)were higher than those patients with no MODS group(18.62±4.06 scores,16.69±3.54 scores,63.98±7.52 ng/ml,25.43±3.97 pg/ml),and the differences were statistically significant(t=7.265,7.783,9.994,12.766,all P<0.05).The AUCs of serum Syndecan-1 and PTX-3 for predicting the prognosis of patients with multiple injuries and MODS alone were 0.845 and 0.792,respectively,while the AUC of combined diagnosis of the two was 0.941,and the diagnostic value of the combination of the two for multiple injuries with MODS was superior to that of Syndecan-1 and PTX-3 separately(Z=4.029,2.681,P=0.001,0.007),while the sensitivity of the combined diagnosis of the two was significantly higher than that of conventional inflammatory indicators IL-6 and PCT diagnosis.The expression levels of Syndecan-1(85.17±9.03ng/ml)and PTX-3(40.20±5.21 pg/ml)in the serum of patients in the death group were higher than those in the survival group(67.90±7.22 ng/ml,27.77±3.64 pg/ml),and the differences were statistically significant(t=7.201,9.345,all P<0.05).The AUCs predicted by serum Syndecan-1 and PTX-3 alone were 0.845 and 0.792,respectively,while the AUC predicted by the combination of the two was 0.932.The combined prediction of multiple injuries with MODS was superior to Syndecan-1 and PTX-3 separately(Z=1.982,2.311,P=0.047,0.020),and it has certain predictive value for the prognosis of patients with multiple injuries combined with MODS.Conclusion The expression levels of Syndecan-1 and PTX-3 in serum are related to the occurrence of multiple injuries with MODS.The combined detection of the two has high diagnostic and prognostic value for multiple injuries with MODS.
