Methods: We conducted a cross section study of 70 patients presented to the nephrology clinic over a period of one year. We compared the Glomerular Filtration Rate by these two formulas in five stages of Chronic Kidney Disease. Abbreviated 4 variable Modification of Diet in Renal Disease formula was used.Results: Age range was 15 - 79 years;Male 49%, Female 51%. The correlation (r) between eGFR by MDRD and eGFR by Cockcroft-Gault equation for CKD stages 1 to 5 was 0.64;0.31;0.32;0.67;and 0.45 respectively. The correlation (r) between creatinine clearance by 24 hour urine collection and MDRD formula was 0.84 (P: 0.001). The correlation (r) between creatinine clearance by 24 hour urine collection Cockcroft-Gault equation was 0.79 (P: 0.001). Conclusion: We conclude that Cockcroft-Gault equation correlates best with MDRD formula at CKD stages 4 and one. Cockcroft-Gault equation underestimated eGFR in stages 1, 2 and 3 of chronic Kidney Disease.展开更多

目的:以99mTc-DPTA血浆清除率为标准,对24h内生肌酐清除率(Ccr)、Cockcroft-Gault(CG)方程和简化MDRD(modification of diet in renal disease)方程进行比较,评价三种方程在慢性肾脏疾病(CKD)患者中的应用。方法:选择139例各种慢性肾脏...目的:以99mTc-DPTA血浆清除率为标准,对24h内生肌酐清除率(Ccr)、Cockcroft-Gault(CG)方程和简化MDRD(modification of diet in renal disease)方程进行比较,评价三种方程在慢性肾脏疾病(CKD)患者中的应用。方法:选择139例各种慢性肾脏疾病患者,将Ccr、CG方程和简化MDRM方程估算的肾小球滤过率(GFR)用体表面积(BSA)标准化,与BSA标准化的99mTc-DTPA测得的GFR(99mTc-GFR)在不同CKD分期进行比较。结果:CKD第一至第五期:Ccr与99mTc-GFR相关系数r分别为:0.79、0.71、0.64、0.59、0.52;Ccr在ROC曲线下面积平均为0.79。CG-GFR与99mTc-GFR相关系数r分别为:0.85、0.78、0.72、0.67、0.61;CG-GFR在ROC曲线下面积平均为0.83。MDRD-GFR与99mTc-GFR相关系数r分别为:0.83、0.76、0.69、0.65、0.59;MDRD-GFR在ROC曲线下面积平均为0.82。在CKD不同分期三种方程的GFR估算值与99mTc-GFR差异均有显著意义(P均<0.001)。结论:三种方程的GFR估算值与99mTc-GFR均有较好的相关性和ROC曲线下面积,以CG方程最好,其次为简化MDRD方程,Ccr最低,但三种方程估算值与99mTc-GFR测定值差异均有显著意义。上述方程直接应用于我国CKD患者时,应对其进行适当修正。展开更多
