目的评价3种慢性肾脏病流行病学合作组(CKD-EPI)公式和改良MDRD公式计算估算肾小球滤过率(eGFR)的一致性。方法选取2014年12月—2015年10月在中国人民解放军成都军区总医院内分泌科住院的178例2型糖尿病患者,分别采用CKD-EPI_(2009Scr)、CKD-EPI_(2012Cys-C)、CKD-EPI_(2012Scr-Cys-C)公式和改良MDRD公式计算eGFR,评估3种CKD-EPI公式与改良MDRD公式计算eGFR的一致性。采用改良MDRD公式计算的eGFR进行慢性肾脏病(CKD)分期,比较CKD 1~5期CKD-EPI_(2009Scr)、CKD-EPI_(2012Cys-C)、CKD-EPI_(2012Scr-Cys-C)公式和改良MDRD公式的差异。以改良MDRD公式eGFR<60 ml·min^(-1)·(1.73 m^2)^(-1)诊断糖尿病肾病,利用受试者工作特征(ROC)曲线评估3种CKD-EPI公式诊断糖尿病肾病的eGFR截点。结果 4种公式计算的eGFR分别为:CKD-EPI_(2009Scr)公式为(88±29)ml·min^(-1)·(1.73 m^2)^(-1),CKD-EPI_(2012Cys-C)公式为(85±33)ml·min^(-1)·(1.73 m^2)^(-1),CKD-EPI_(2012Scr-Cys-C)公式为(88±32)ml·min^(-1)·(1.73 m^2)^(-1),改良MDRD公式为(112±49)ml·min^(-1)·(1.73 m^2)^(-1)。改良MDRD公式计算的eGFR分别与3种CKD-EPI公式计算的eGFR比较,差异均有统计学意义(t=5.564、5.945、5.267,P<0.001)。改良MDRD公式与CKD-EPI公式计算的eGFR的Bland-Altman分析图显示CKD-EPI公式与改良MDRD公式计算的eGFR一致性欠佳。改良MDRD公式分别与3种CKD-EPI公式计算的eGFR的差值随血肌酐(Scr)水平的升高逐渐缩小(R^2=0.239、0.186、0.195)。CKD 1期和CKD 2期4种公式计算的eGFR比较,差异均有统计学意义(P<0.001);其中改良MDRD公式计算的eGFR均分别高于3种CKD-EPI公式(P<0.05)。CKD 3期、CKD 4期和CKD 5期4种公式计算的eGFR比较,差异均无统计学意义(P>0.05)。CKD-EPI_(2009Scr)、CKD-EPI_(2012Cys-C)、CKD-EPI_(2012Scr-Cys-C)公式诊断糖尿病肾病的eGFR截点分别为61、65、61 ml·min^(-1)·(1.73 m^2)^(-1),ROC曲线下面积分别为0.992、0.937、0.977。结论与改良MDRD公式相比,3种CKD-EPI公式会�
Objective To evaluate the consistency between three chronic kidney disease epidemiology collaboration(CKD-EPI) equations and modified modification of diet in renal disease(MDRD) equation for estimated glomerular filtration rate(eGFR).Methods From December 2014 to October 2015,178 adult patients with type 2 diabetes mellitus admitted to Department of Endocrinology,Chengdu Military General Hospital were recruited.The eGFR was calculated using CKD-EPI(2009Scr),CKD-EPI(2012Cys-C),CKD-EPI(2012Scr-Cys-C) and modified MDRD equations,respectively.Consistency between the three CKD-EPI and modified MDRD equations was evaluated.Chronic kidney disease(CKD) was staged according to eGFR calculated using modified MDRD equation.The differences were compared among CKD-EPI(2009Scr),CKD-EPI(2012Cys-C),CKD-EPI(2012Scr-Cys-C) and modified MDRD equations.Diabetic kidney disease was defined as eGFR less than 60 ml· min^·(1.73 m),calculated using modified MDRD equation.The cut points of CKD-EPI(2009Scr),CKD-EPI(2012Cys-C)and CKD-EPI(2012Scr-Cys-C) for diagnosing diabetic kidney disease were evaluated by receiver operating characteristic(ROC) curve.Results The eGFR calculated using CKD-EPI(2009Scr),CKD-EPI(2012Cys-C),CKD-EPI(2012Scr-Cys-C) and modified MDRD equations were(88 ± 29) ml· min^-1·(1.73m^2)^-1,(85 ±33) ml· min^-1·(1.73 m^2)^-1,(88±32) ml· min^-1·(1.73 m^2)^-1 and(112 ± 49) ml·min^-1·(1.73 m^2)^-1,respectively.There were statitically significant difference between the eGFR calculated using CKD-EPI(2009Scr),CKD-EPI(2012Cys-C) and CKD-EPI(2012Scr-Cys-C) and modified MDRD equations(t = 5.564,5.945,5.267,P〈0.001).Bland-Altman plots illustrated the eGFR calculated by the three CKD-EPI equations had poor agreement with modified MDRD equation.The difference between modified MDRD and three CKD-EPI equations in calculating eGFR reduced with elevating serum creatine(Scr)(R^2 =0.239,0.186,0.195).T
