BACKGROUND/AIMS: recently, the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) proposed a new equation for estimating glomerular filtration rate (eGFR), which could potentially replace the Modified Diet for Renal Disease Study (MDRD) equation in routine clinical use. Our aim was to evaluate the correlation between them and to compare the prevalence of each CKD stage using these two equations. METHODS: we measured serum creatinine in 38,188 consecutive patients and calculated eGFR using the CKD-EPI and MDRD equations. We also compared the distribution of CKD stages for both equations. RESULTS: there was very good correlation between eGFR estimated by CKD-EPI and MDRD at values < 60 ml/min × 1.73 m2, but not at higher values. Estimated prevalence of CKD (eGFR < 60 ml/min × 1.73 m2) was 5.9% with CKD-EPI and 7.5% with MDRD. Furthermore, the prevalence of CKD Stage 2 was lower with CKD-EPI (33.8% vs. 49.1%. with MDRD). CONCLUSION: the use of the CKD-EPI equation results in a lower estimated prevalence of CKD, compared to the MDRD equation. This may have important implications for public health and clinical practice, as well as for future modification of guidelines for laboratories.
