Comparison of creatinine, cystatin, CKD-EPI cystatin C, CKD-EPI creatinine and MDRD equations in estimating glomerular filtration rate in patients with nephrotic syndrome

Abstract

Objective: It’s recommended to use equations such as Modification of Diet in Renal Disease (MDRD) and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) by using creatinine level in estimating glomerular filtration rate (GFR). Here, we aimed to compare serum cystatin-C (Cys-C) and Cys-C based equations with creatinine and creatinine based equations in patients with chronic kidney disease (CKD) and nephrotic syndrome (NS).
