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.
