摘要
目的:探讨血清尿调节素(UMOD)检测在原发性高血压病患者早期肾损伤中的诊断价值。方法:选择2017-01—2018-01期间在我科治疗的236例原发性患者纳入研究,按照肾小球滤过率(GFR)将患者分为3组,中度及以上肾功能损伤组[A组,GFR<60 ml/(min·1.73 m2)],轻度肾功能损伤组[B组,60 ml/(min·1.73m2)≤GFR<90ml/(min·1.73m2)]和肾功能正常组[C组,GFR≥90ml/(min·1.73m2)]。另选择100例同期于我院行健康体检志愿者作为对照组(D组)。采用酶联免疫吸附试验法(ELISA)检测各组标本UMOD水平。结果:A组血清UMOD水平显著低于B组及C组,B组血清UMOD水平明显低于C组(均P<0.05)。血清UMOD与GFR呈正相关关系(r=0.387,P<0.01),与尿素氮、尿酸、肌酐、胱抑素C和尿微量白蛋白均呈负相关关系(r=-0.206、-0.175、-0.318、-0.352、-0.284,均P<0.05)。根据受试者工作特征(ROC)曲线,血清UMOD诊断原发性高血压患者早期肾损伤的最佳临界点为127.3 mg/ml,对应敏感性、特异性分别为72.5%和83.8%,ROC曲线下面积为0.816。结论:血清UMOD可能成为原发性高血压患者早期肾损伤新的诊断指标之一。
Objective:To observe the diagnostic value of serum Uromodulin(UMOD)on early renal damage in patients with essential hypertension.Method:Two hundred and thirty-six essential hypertension patients in our hospital from January 2017 to January 2018 were selected into this study.According the glomerular filtration rate,they were divided into 3 groups,group of moderate and above renal damage[A group,GFR60 ml/(min·1.73 m^2)],group of mild renal damage[B group,60 ml/(min·1.73 m^2)≤GFR90 ml/(min·1.73 m^2)]and group of normal kidney function[C group,GFR≥90 ml/(min·1.73 m^2)].Meanwhile,100 healthy volunteers were also selected into this study as control(D group).ELISA was used to detect serum levels of UMOD.Result:The serum UMOD level in the A group was lower than those of in B group and C group(both P〈0.05).The serum UMOD level in the B group was also lower than that of C group(P〈0.05).The serum UMOD level was significantly positively related to GFR(r=0.387,P〈0.01).Meanwhile,serum UMOD level was significantly inversely associated with Urea nitrogen,uric acid,creatinine,cystatin C and urinary microalbumin(r=-0.206,-0.175,-0.318,-0.352,-0.284,all P〈0.05).Based on the ROC curve,the boundary value of serum UMOD was 127.3 mg/ml for diagnosing early renal damage in patients with essential hypertension.The sensitivity and specificity of serum UMOD in diagnosis of early renal damage were 72.5% and 83.8%,respectively.The area under the ROC curve was 0.816 of serum UMOD in diagnosis of early renal damage in patients with essential hypertension.Conclusion:The serum UMOD may be applied to burst diagnosis of early renal damage in patients with essential hypertension.
