Abstract:
Objective To explore the value of carotid pulse wave combined with urinary transferrin(TRF)and β2-microglobulin(β2-MG)in the evaluation of renal injury in patients with hyperten-sive nephropathy.Methods A total of 30 patients with hypertensive nephropathy,30 patients with simple hypertension and 90 patients with non-hypertensive nephropathy who were admitted to our hospital between May 2021 and April 2024,and 30 healthy individuals(control group)who taking physical examination during same period were enrolled and assigned into corresponding groups,respectively.According to the severity of renal injury,the 120 patients from the hyperten-sive nephropathy group and non-hypertensive nephropathy group were divided into normal group(28 cases),mildly injured group(36 cases),moderately injured group(31 cases)and severely in-jured group(25 cases).The carotid pulse wave indicators[pulse wave velocity at beginning of the systole(PWV-BS),pulse wave velocity at ending of the systole(PWV-ES)],and urinary TRF and β2-MG levels were detected and compared in above groups.ROC curves were plotted to ana-lyze the diagnostic values of these indicators in hypertensive nephropathy.The relationship be-tween the above indicators and the severity of renal injury was analyzed with sequential multivari-ate logistics regression analysis.Results There were significant differences in PWV-BS,PWV-ES,and urinary TRF and β2-MG levels among the hypertensive nephropathy group,non-hyperten-sive nephropathy group,hypertension group and control group(P＜0.01).ROC curve analysis showed that the AUC value of the four indictors combined together in the diagnosis of hyperten-sive nephropathy was 0.907,which was statistically greater than that of single indicator alone(0.774,0.743,0.728,0.749,P＜0.01).Obvious differences were also observed in PWV-BS,PWV-ES,and urinary TRF and β2-MG levels among the severely,moderately and mildly injured groups and normal group(P＜0.01).Sequential multivariate logistics regression analysis indicated that PWV-BS(OR=1.824,95％CI:1.272-2.616,P=0.001),PWV-ES(OR=1.910,95％CI:1.268-2.877,P=0.002),and urinary TRF(OR=2.442,95％CI:1.485-4.018,P=0.001)and β2-MG levels(OR=2.807,95％CI:1.580-4.984,P=0.001)were influencing factors of renal injury severity in the renal injured patients.Conclusion Carotid pulse wave combined with urinary TRF and β2-MG can be applied in auxiliary diagnosis of hypertensive nephropathy,and they are correla-ted with the severity of renal injury.
