MDRD VERSUS CKD-EPI EQUATIONS TO ESTIMATE GLOMERULAR FILTRATION RATE IN OBESE PATIENTS

Introduction and Aims: Obesity is recognized as a risk factor both for the development and progression of chronic kidney disease (CKD). Estimating glomerular filtration rate (GFR) is thus especially important to follow these patients. We have tested the performances of two creatinine-based equations, namely the MDRD and CKD-EPI equations, in an obese population. Conclusions :Both in the global and subgroup analyses, the CKD-EPI equation did not outperform the MDRD study equation. The performances of both equations were worse in CKD patients. These two conclusions were still valid if indexed GFR was considered.
