Abstract:
Objective To investigate the predictive value of serum homocysteine(HCY)and lipoprotein(a)[Lp(a)]in autologous arteriovenous fistula(AVF)failure in patients undergoing maintenance hemodialy-sis(MHD).Methods A total of 175 patients with MHD admitted to the hospital from January to December 2022 were selected as the observation group,among them,103 patients without AVF failure were selected as observation group 1,and 72 patients with AVF failure were selected as observation group 2.175 healthy indi-viduals who underwent physical examinations at the outpatient examination center of the hospital during the same period were selected as the control group.Enzyme-linked immunosorbent assay was used to detect the levels of HCY and Lp(a).Pearson method was used to analyze the correlation between HCY,Lp(a)with clin-ical indicators.Multivariate Logistic regression analysis was performed to analyze the influencing factors of AVF failure in MHD patients.Receiver operating characteristic(ROC)curve was plotted to analyze the pre-dictive value of serum HCY and Lp(a)for AVF failure in MHD patients.Results Compared with the control group,the serum levels of HCY and Lp(a)in observation group 1 were increased(P<0.05).Compared with the control group and observation group 1,the serum levels of HCY and Lp(a)in observation group 2 were in-creased(P<0.05).The serum levels of HCY and Lp(a)in observation group 2 were negatively correlated with ultrafiltration amount(P<0.05),and HCY and Lp(a)were positively correlated with parathyroid hor-mone(PTH),blood phosphorus(P),uric acid(UA)(P<0.05).Multivariate Logistic regression analysis showed that HCY,Lp(a),PTH,P,UA,diabetic nephropathy,duration of endovascular fistula use≥12 months,duration of puncture point compression≥30 min,and arteriovenous internal diameter<2 mm and vascular stenosis were the risk factors for AVF failure in MHD patients(P<0.05),and ultrafiltration a-mount was a protective factor for AVF failure in MHD patients(P<0.05).ROC curve results showed that the area under the curve of HCY and Lp(a)alone and in combination in the prediction of AVF failure in MHD patients were 0.822,0.820 and 0.908,respectively(Zcombination vs.HCY=3.144,Zcombination vs.Lp(a)=2.925,P<0.05).Conclusion The serum levels of HCY and Lp(a)in MHD patients with AVF failure are increased.They are the influencing factors of AVF failure in MHD patients,and the value of the combination of the two for pre-dicting AVF failure in MHD patients is relatively high.
