BACKGROUND Renal function is often estimated using one of several glomerular filtration rate (GFR) estimating equations. However, there is no consensus which estimating equation performs best in patients with advanced renal failure. METHODS We compared the performance of five different estimated GFR (eGFR) equations [Cockcroft-Gault, Modification of Diet in Renal Disease (MDRD), Chronic Kidne...

OBJECTIVES Cystatin C is emerging as an endogenous marker of glomerular filtration rate. This study sought to assess the usefulness of serum cystatin C as a marker of glomerular filtration rate in comparison with serum creatinine and serum creatinine-based glomerular filtration rate estimations in voluntary kidney donors. MATERIALS AND METHODS Serum cystatin C and serum creatinine were estima...

INTRODUCTION AND OBJECTIVES New oral anticoagulants require dosing adjustment according to renal function. We aimed to determine discordance in hypothetical recommended dosing of these drugs using different estimated glomerular filtration rate equations in patients with atrial fibrillation. METHODS Cross-sectional analysis of 910 patients with atrial fibrillation and an indication for oral an...

AIMS Atrial fibrillation (AF) is common among patients with impaired renal function. Apixaban, a novel oral anticoagulant with partial renal excretion, was compared with warfarin and reduced the rate stroke, death and bleeding in the ARISTOTLE trial. We evaluated these outcomes in relation to renal function. METHODS AND RESULTS Baseline glomerular filtration rate (GFR) was estimated using the...

BACKGROUND/AIMS Although the National Kidney Disease Education Program recommends use of the modification of diet in renal disease (MDRD) formula to estimate the glomerular filtration rate (GFR), most drug-dosing recommendations and clinical practices employ the Cockcroft-Gault (CG) formula. The quality score of the original MDRD study was better than that of the original CG study, although the...

introduction: we intended to assess the accuracy of re-expressed modification of diet for renal disease (mdrd) and cockcroft-gault (cg) equations to estimate glomerular filtration rate (gfr) in chronic kidney disease in two different etiologies of acute renal failure (arf): acute tubular necrosis (atn) and acute glomerulonephritis (agn). methods: patients admitted for arf or the patients compl...

Background/Aims: Although the National Kidney Disease Education Program recommends use of the modification of diet in renal disease (MDRD) formula to estimate the glomerular filtration rate (GFR), most drug-dosing recommendations and clinical practices employ the Cockcroft-Gault (CG) formula. The quality score of the original MDRD study was better than that of the original CG study, although th...
