Resumen

ROSA-DIEZ, Guillermo J. et al. Comparison between CKD-EPI and MDRD-equations to estimate glomerular filtration rate in chronic kidney disease patients. Medicina (B. Aires) [online]. 2011, vol.71, n.4, pp. 323-330. ISSN 0025-7680.

The MDRD equation to estimate glomerular filtration rate (GFR) is the most widely used strategy to assess chronic kidney disease. Nonetheless, for the individual patient the true GFR can be underestimated with the risk of diagnosing a more elevated CKD stage. This novel CKD-EPI equation would improve accuracy and precision of estimations, and several authors recommend this new equation replace the former. In our country there is only a limited registration of these comparisons performed on a large number of patients. Therefore, our aim was to develop a comparison in a wide cohort of patients. The concordance between both equations to assign the GFR stages was determined by using the MDRD formula as a reference. The mean difference of GFR obtained with both equations as well as the Bland-Altman analysis were calculated. A cohort of 9 319 individuals, of whom 67% were females, aged 58 ± 20 years, with serum creatinine values of 1.6 ± 1.03 mg/dl, was studied. In the whole group, CKD-EPI displayed an average GFR 0.61 ml/min/1.73 m2 larger than MDRD (p: NS). For CKD stages 2 and 3A the mean estimated GFR difference was 6.95 ± 4.76 and 3.21 ± 3.31, while the concordance was 81 and 74% respectively. The percentage of patients with GFR < 60 ml/min/1.73 m2, decreased from 76.3% with the former equation to 70.1% with the latter. The novel equation CKD-EPI reduces the number of patients with GFR values lower than 60 ml/min/1.73 m2 and consequently assigns a higher GFR stage to a considerable quantity of individuals.
