【摘要】 目的 評價簡化腎臟病膳食改良試驗(MDRDa)方程以及國內兩個改良MDRD方程(中國方程1、2)預測中國慢性腎臟病患者腎小球濾過率(glomerular filtration rate,GFR)的適用性。 方法 選擇2008年1-12月住院慢性腎病患者250例,用99mTc-DTPA腎動態顯像法測定GFR(sGFR),同時測定血清肌酐、尿素氮,根據年齡和性別分別用簡化MDRD方程、中國方程1和中國方程2預測GFR,即eGFRa (簡化MDRD方程)、eGFR1 (中國方程1)和eGFR2(中國方程2),以sGFR為參考值,將估計的eGFRs進行比較。 結果 各方程eGFRs與sGFR之間呈顯著相關關系。其中中國方程2的估算eGFR2與sGFR具有良好的一致性,總體偏差最小,準確性最高。 結論 中國方程2優于簡化MDRD方程和中國方程1,可用于中國慢性腎病人群eGFR的計算。
【Abstract】 Objective To evaluate the applicability of three equations for glomerular filtration rate (GFR) in Chinese patients with chronic kidney disease (CKD). Methods A total of 250 patients with CKD which were diagnosed according to K/DAQI guidelines between January and December 2008 were selected. GFR were estimated with Chinese equation 1 (eGFR1), Chinese equation 2 (eGFR2) and abbreviated MDRD (eGFRa) separately, and the results were compared with that of 99mTc-DTPA(sGFR). Results The eGFRs of the three equations were correlated significantly with sGFR. Chinese equation 2 seemed to be the best; eGFR2 showed less bias and higher accuracy than other equations. Conclusion Chinese equation 2 for estimation of GFR may be more accurate in Chinese CKD patients.
