摘要:

目的 分析血浆生物标志物在慢性肾脏病(CKD)伴血栓栓塞患者中的表达及其在近期预后评估中的价值。方法 选取2018年5月—2022年5月承德市中心医院93例CKD伴血栓栓塞患者(研究组),以93例单纯CKD患者作为对照组。检测所有患者血浆D-二聚体(DD)、生长停滞特异性蛋白6(GAS6)、血小板α颗粒膜糖蛋白(CD62P)、纤维蛋白原(Fib)水平。随访3个月以了解患者近期预后情况。采用Logistic回归分析评估近期预后影响因素,建立列线图预测模型。采用受试者工作特征(ROC)曲线评价血浆DD、GAS6、CD62P、Fib单独和联合检测判断CKD伴血栓栓塞患者近期预后的效能。结果 研究组血浆DD、GAS6、CD62P、Fib水平均高于对照组(P<0.05);研究组预后不良发生率为24.73%。根据预后情况分为预后不良组(23例)和预后良好组(70例),2个组血栓栓塞类型和血浆DD、GAS6、CD62P、Fib 差异有统计学意义(P<0.05)。血浆DD、GAS6、CD62P、Fib是CKD伴血栓栓塞患者近期预后不良的影响因素(P<0.001)。ROC曲线分析结果显示,血浆DD、GAS6、CD62P、Fib单项检测诊断CKD伴血栓栓塞患者近期预后不良的曲线下面积(AUC)[95%可信区间(CI)]分别为0.784(0.687~0.863)、0763(0.664~0.845)、0.824(0.731~0.895)、0.794(0.698~0.871),GAS6+CD62P+DD、GAS6+CD62P+Fib、CD62P+Fib+DD的AUC差异均无统计学意义(P>0.05)。根据4个危险因素建立CKD伴血栓栓塞患者近期预后列线图预测模型,结果显示,该列线图预测模型判断CKD伴血栓栓塞患者近期预后的AUC(95%CI)为0.866(0.812~0.945);校准度曲线显示,该列线图预测模型在GiViTI校准曲线带的80%~95%CI区域均未穿过45°角平分线。结论 血浆DD、GAS6、CD62P、Fib在CKD伴血栓栓塞患者中呈高表达,4项指标联合检测可提高近期预后评估价值,有助于指导后续的个体化治疗。

Abstract:

Objective To investigate the expression and near-term prognostic predictive value of plasma biomarkers in chronic kidney disease(CKD) patients with thromboembolism. Methods Totally,93 CKD patients with thromboembolism in Chengde Central Hospital from May 2018 to May 2022 were enrolled as study group,and another 93 patients with CKD alone were enrolled as control group. Plasma biomarkers [D-dimer(DD),growth arrest-specific protein 6(GAS6),platelet alpha-granular membrane protein(CD62P) and fibrinogen(Fib)] and near-term prognosis were determined. Logistic regression analysis was used to screen for near-term prognostic factors,and a line graph prediction model was developed. Receiver operating characteristic(ROC) curve was used to evaluate the efficacy of plasma DD,GAS6,CD62P,Fib single and combined determinations in evaluating the near-term prognosis of CKD patients with thromboembolism. Results Plasma DD,GAS6,CD62P and Fib levels were higher in study group than those in control group(P<0.05). The study group received a follow-up with a 24.73% incidence of poor prognosis and was classified into poor prognosis group(23 cases) and good prognosis group(70 cases) according to the incidence of poor prognosis. The type of thromboembolism and plasma DD,GAS6,CD62P and Fib were statistically significant between the 2 groups(P<0.05). Plasma DD,GAS6,CD62P and Fib were factors on the near-term poor prognosis in CKD patients with thromboembolism(P<0.001). ROC curve analysis showed that the areas under curves(AUC) [95% confidence interval(CI)] for plasma DD,GAS6,CD62P and Fib for the diagnosis of near-term prognosis in CKD patients with thromboembolism were 0.784(0.687-0.863],0.763(0.664-0.845),0.824(0.731-0.895) and 0.794(0.698-0.871),and there was no statistical significance for the AUC of GAS6+CD62P+DD,GAS6+CD62P+Fib and CD62P+Fib+DD(P>0.05). A predictive model for the near-term prognosis of CKD patients with thromboembolism was established based on the 4 risk factors of the line graph prediction model. The AUC of this line graph prediction model was 0.866(0.812-0.945),and the calibration curve showed that the line graph prediction model did not cross the 45° angle parity in the 80%-95%CI of the GiViTI calibration curve band. Conclusions Plasma DD,GAS6,CD62P and Fib are highly expressed in CKD patients with thromboembolism,and the combination of the 4 indicators could help improve the predictive value of near-term prognosis and guide the subsequent individualized treatment of patients.
