ABSTRACT
Objective: To evaluate the applicability of modified MDRD equation in predicting Glomerular filtration rate in patients with chronic kidney disease (CKD). Methods: Totally 481 CKD patients, who were diagnosed based on K/DOQI guideline from Jan. 2005 to Jan. 2007 in our hospital, were enrolled in this study. The sex, age, body weight and height of patients were recorded; the plasma creatinine, serum albumin and 99mTc-GFR (standardized by body surface area) were measured. GFRs were estimated by abbreviated MDRD equation and the modified MDRD equation separately. The bias, accuracy and precision of both equations were compared. Results: The estimated GFRs (eGFRs) by both equations were significantly correlated with the rGFR(P<0.01). Except for the slightly decreased precision, the modified MDRD equation showed great improvements in the 5%, 30%, and 50% accuracy and bias when compared with the original abbreviated MDRD equation(P<0.05). Compared with the original equation, the modified MDRD equation showed smaller bias in all stages of CKD except for stage 5(P<0.05). The modified MDRD equation also decreased the absolute bias and improved the 30% accuracy in stage 2 CKD (P<0.01). Conclusion: Compared with original equation, the modified MDRD equation has great advantages in predicting the total GFR and GFRs at different CKD stages. Currently it can be used in predicting the GFR of Chinese CKD patients.
