摘要:

摘要:目的:评价CKD-EPI方程在中国早期肾脏病患者人群中的适用性。方法:选择528例南京地区慢性肾脏病患者,对其以CKD-EPI方程与中国人修正改良简化MDRD方程分别估算GFR(cGFR和mGFR),并进行比较。结果:CKD-EPI方程与改良简化MDRD方程两方程相关性良好(r=0.755,P<0.001)。但CKD-EPI方程计算平均cGFR低于改良简化MDRD方程计算平均mGFR,两者差异有统计学意义(P<0.05);根据CKD-EPI方程计算cGFR和改良简化MDRD方程计算mGFR进行CKD分期,比较两者间各CKD分期人数百分比,两者CKD1期、CKD2期间比较有统计学意义(P<0.05),两者CKD3期间比较无统计学意义(P>0.05),比较两者间各CKD分期GFR,两者CKD1期、CKD2期间比较有统计学意义(P<0.05),两者CKD3期间比较无统计学意义(P>0.05)。结论:GFR> 60ml/(min.1.73m2)时,CKD-EPI方程较改良简化MDRD方程存在低估GFR的倾向,能否取代中国人改良简化MDRD方程尚需进一步研究。

Abstract: Objective To evaluate the applicability of the CKD-EPI equation in the Chinese patients with early chronic kidney disease . Methods 528 patients of Nanjing with chronic kidney disease were investigated. The CKD-EPI equation estimated GFR(cGFR) was compared with the simplified MDRD equation estimated GFR(mGFR).Results There were fine correlation(r=0.755,P<0.001) and significant difference(P <0.05) between cGFR and mGFR.The CKD-EPI equation and modified to simplify the two equations of the MDRD equation. The percentages and GFRs of the both CKD1 and CKD2 stage according to the cGFR and mGFR were significantly different(P <0.05).And there was no significant difference of the percentages and GFRs of the CKD3 stage (P> 0.05). Conclusions: It exists a tendency to underestimate GFR in Chinese patients with CKD of CKD-EPI equation compared with the simplified MDRD equation when GFR> 60ml / (min.1.73m2).More further studies are still needed to probe whether CKD-EPI equation could replace the simplified MDRD equation.
