目的
2
探究急性肺血栓栓塞症(PTE)患者血浆血管性血友病因子(vWF)活性、血管性血友病因子裂解酶(ADAMTS-13)活性、中性粒细胞计数与淋巴细胞计数比率(NLR)健康对照组的表达差异,探究ADAMTS-13活性、NLR对于PTE患者的诊断意义。
方法
2
共纳入急性PTE患者64例及健康对照者30例,收集相关临床数据并采用酶联免疫吸附试验(ELISA)检测血浆ADAMTS-13活性、vWF活性,分析比较ADAMTS-13活性、vWF活性的组间差异及其与其他临床指标的相关性,绘制受试者工作特征曲线(ROC)评价ADAMTS-13活性及NLR对急性PTE患者的诊断价值。
结果
2
健康对照组与急性PTE组ADAMTS-13活性水平分别为83.8%(72.2%, 98.8%)、63.3%(49.6%, 74.8%),vWF活性水平分别为102.7%(89.7%, 117.2%)、122.6%(96.8%, 156.6%),组间差异均具有统计学意义(
P
<0.05),ADAMTS-13活性与vWF活性、D-二聚体水平呈负线性相关(
P
<0.05)。多因素Logistic回归结果示NLR的升高为患急性PTE的独立危险因素[OR=1.66,95% CI(1.10, 2.47),
P
=0.014],ADAMTS-13活性的升高为患急性PTE的独立保护因素[OR=0.92,95% CI(0.88, 0.96),
P
<0.001]。ADAMTS-13活性用于诊断急性PTE时,ROC曲线下面积(AUC)为0.861,95%CI(0.780, 0.942),
P
<0.001,联合NLR用于诊断急性PTE时,AUC为0.902,95%CI(0.841, 0.963),
P
<0.001。
结论
2
急性PTE患者血浆ADAMTS-13活性显著下降,vWF活性显著上升,ADAMTS-13、vWF或为沟通血栓形成与炎症反应间的桥梁,血浆ADAMTS-13活性联合NLR可提高诊断急性PTE的准确性,为探寻急性PTE的致病机制提供新的思路,为探寻急性PTE治疗靶点提供实验依据。
Objective
2
The purpose of this study was to compare the expression of plasma vWF activity, ADAMTS-13 activity and neutrophil-to-lymphocyte ratio (NLR) between patients with acute pulmonary thromboembolism (PTE) and healthy controls, and to explore the clinical value of plasma ADAMTS-13 activity and NLR in diagnosis of acute PTE.
Methods
2
Totally 64 patients with acute PTE and 30 healthy controls were included. Collected clinical data and detected the plasma vWF activity and ADAMTS-13 activity by enzyme linked immunosorbent assay (Elisa). The correlation between ADAMTS-13 activity and other clinical indexes was explored. Receiver operating characteristic curve (ROC) was mapped to evaluate the activity of ADAMTS-13 and NLR in the diagnosis of patients with acute PTE.
Results
2
The comparison between the healthy control group and the acute pulmonary thromboembolism group showed that the ADAMTS-13 activity levels were 83.8% (72.2%, 98.8%) and 63.3% (49.6%, 74.8%), respectively, the VWF activity levels were 102.7% (89.7%, 117.2%) and 122.6% (96.8%, 156.6%), respectively, and the differences between the two groups were statistically significant (
P
<0.05). Spearman correlation analysis showed that there was a negative linear correlation between ADAMTS-13 activity and vWF activity with D-dimer (
P
<0.05). The results of multivariate Logistic regression showed that the increase of NLR was an independent risk factor for acute PTE [OR=1.66, 95% CI (1.10, 2.47),
P
=0.014] and the increase of ADAMTS-13 activity was an independent protective factor for acute PTE [OR=0.92, 95% CI (0.88, 0.964),
P
<0.001]. When used in the diagnosis of acute PTE, the area under the curve (AUC) for ADAMTS-13 activity was 0.861, 95%CI (0.780, 0.942),
P
<0.001. When combined with NLR, the AUC was 0.902, 95%CI(0.841, 0.963),
P
<0.001.
Conclusions
2
Our results show plasma ADAMTS-13 activity is significantly decreased and vWF activity is significantly increased in patients with acute PTE. ADAMTS-13 and vWF may be the bridge between thrombosis and inflammation. Combined with NLR, plasma ADAMTS-13 activity can improve the accuracy of diagnosis of acute PTE. Our results provide new ideas for exploring the pathogenic mechanism of acute PTE, and provide experimental basis for exploring therapeutic target of acute PTE.
