摘要
目的 探讨颈动脉脉搏波结合尿转铁蛋白(transferrin, TRF)、β_(2)微球蛋白(β_(2)-microglobulin, β_(2)-MG)对高血压肾病患者肾损伤的评估价值。方法 选取2021年5月至2024年4月河北医科大学第三医院住院的高血压肾病患者30例(高血压肾病组),单纯高血压患者30例(高血压组),非高血压肾病患者90例(非高血压肾病组),另选取同期健康体检者30例(对照组)。高血压肾病及非高血压肾病患者120例,又根据肾功能损伤程度分为正常组28例、轻度损伤组36例、中度损伤组31例及重度损伤组25例。检测并比较各组颈动脉脉搏波指标[收缩期开始时脉搏波传导速度(pulse wave velocity at beginning of the systole, PWV-BS)、收缩期结束时脉搏波传导速度(pulse wave velocity at ending of the systole, PWV-ES)]、尿TRF及β_(2)-MG水平。采用ROC曲线分析各指标诊断高血压肾病的价值,有序多分类logistics回归分析各指标与肾功能损伤程度的关系。结果 高血压肾病组、非高血压肾病组、高血压组、对照组PWV-BS、PWV-ES、尿TRF及β_(2)-MG水平比较,差异有统计学意义(P<0.01)。ROC曲线分析显示,PWV-BS、PWV-ES、尿TRF及β_(2)-MG水平联合诊断高血压肾病的曲线下面积为0.907,高于四者单独诊断的0.774、0.743、0.728、0.749(P<0.01)。重度损伤组、中度损伤组、轻度损伤组、正常组PWV-BS、PWV-ES、尿TRF及β_(2)-MG水平比较,差异有统计学意义(P<0.01)。有序多分类logistics回归分析显示,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)、尿TRF(OR=2.442,95%CI:1.485~4.018,P=0.001)及β_(2)-MG(OR=2.807,95%CI:1.580~4.984,P=0.001)是影响肾病患者肾功能损伤程度的危险因素。结论 颈动脉脉搏波结合尿TRF、β_(2)-MG检测可辅助诊断高血压肾病,且与肾功能损伤程度相关。
Objective To explore the value of carotid pulse wave combined with urinary transferrin(TRF)andβz-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 andβ2-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 B2-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 B2-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.
