BACKGROUND Serum cystatin C (SCC)-based formulas and the newer creatinine formula (the Chronic Kidney Disease Epidemiology Collaboration formula (CKD-EPI)) were proposed as improved glomerular filtration rate (GFR) markers. The aim of our study was to compare serum creatinine (SCr)-based and SCC-based equations against (51)Cr-EDTA clearance in patients with mildly to moderately impaired kidney ...

BACKGROUND The most commonly used glomerular filtration rate estimating equations for drug dosing are Cockcroft-Gault (CG), Modification of Diet in Renal Disease (MDRD), Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations. However there is still a concern about whether to use MDRD and CKD-EPI interchangeably with CG for drug dosage adjustment. METHODS The study was initiated...

The effort to improve the identification and management of patients with chronic kidney disease (CKD) is based on implementing more precise means of assessing kidney function and kidney damage in the clinical setting. Over the past decade, the clinical chemistry community has adopted routine reporting of estimated GFR (eGFR) calculated from the Modification of Diet in Renal Disease (MDRD) Study...

BACKGROUND Estimation of the glomerular filtration rate (GFR) at the bedside is important because renal insufficiency is related to increased mortality and morbidity. A discrepancy between the Cockroft-Gault (CG) and the Modification of Diet in Renal Disease (MDRD) formulas has been observed in older people. OBJECTIVE To compare the GFR of inpatients aged 65 or older estimated using the CG an...

BACKGROUND/AIMS Although creatinine-based estimated glomerular filtration rate (eGFR) is associated with cardiovascular events, threshold values for optimum discrimination are unclear. We aimed to identify serum creatinine and eGFR thresholds of maximum sensitivity and specificity (Max(Sn+Sp)) for a composite outcome of coronary heart disease, stroke, and death. METHODS Classification tree me...
