چکیده

OBJECTIVE The best method to estimate glomerular filtration rate (GFR) in diabetic patients is still largely debated. We compared the performance of creatinine-based formulas in a European diabetic population. RESEARCH DESIGN AND METHODS We compared the performance of Cockcroft and Gault, simplified Modification of Diet in Renal Disease (MDRD), and Chronic Kidney Disease Epidemiology (CKD-EPI) Collaboration equations in 246 diabetic patients by calculating the mean bias and the interquartile range (IQR) of the bias, 10% (P10) and 30% (P30) accuracies, and Bland-Altman plots. GFR was measured by inulin clearance. RESULTS For the whole population, the IQR was slightly lower for CKD-EPI, but the mean bias was lower and P10 and P30 were higher for MDRD. Similar results were observed in specific subgroups, including patients with mild renal insufficiency, obese patients, or type 2 diabetic patients. CONCLUSIONS In our population, the CKD-EPI formula does not exhibit better performance than the simplified MDRD formula for estimating GFR.

Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) Equation Pronouncedly Underestimates Glomerular Filtration Rate in Type 2 Diabetes

OBJECTIVE To evaluate the performance of the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation to estimate glomerular filtration rate (GFR) in type 2 diabetic patients with GFR >60 mL/min/1.73 m(2). RESEARCH DESIGN AND METHODS This was a cross-sectional study including 105 type 2 diabetic patients. GFR was measured by (51)Cr-EDTA method and estimated by the MDRD and CKD-EPI e...

Performance of the Chronic Kidney Disease Epidemiology Collaboration equation to estimate glomerular filtration rate in a longitudinal study of Autosomal Dominant Polycystic Kidney Disease

Glomerular filtration rate (GFR) can only be measured indirectly1. The gold standard is the renal clearance of inulin. Because it is cumbersome, alternative methods such as the renal clearance of iothalamate and plasma clearance of iohexol were developed. Other methods estimate GFR using equations based on endogenous filtration markers such as creatinine and cystatin C2. The Chronic Kidney Dise...

Non-albuminuric Diabetic Kidney Disease in Diabetic Patients: A Review

Introduction: The constantly increasing incidence of type 2 diabetes, probably due to obesity and sedentary life, has led to the increased incidence of macro- and microvascular diabetic complications such as nephropathy. Despite the prompt efforts to develop effective treatments for diabetes and slow the progression of its complications, it is still reported as the most common cause of chronic ...

Evaluation of Glomerular Filtration Rate Estimating Formulas in Diabetic Patients with Chronic Kidney Disease

Objective: Measurement of glomerular filtration rate (GFR) is the best determinant in assessment of kidney function for diagnostic and therapeutic purposes. As extremely accurate methods of GFR measurement (i.e. Inulin clearance) are expensive and Time-consuming and due to limitations of the 24 hour urine collection method, some formula have been developed for the GFR measurement. Here we have ...

Validation of El-Minia equation for estimation of glomerular filtration rate in different stages of chronic kidney disease.

INTRODUCTION Assessment of glomerular filtration rate (GFR) is the best index of kidney functions. We aimed to determine the accuracy of El-Minia equation for estimation of GFR in different stages of chronic kidney disease (CKD) in the El-Minia population of CKD patients, in comparison to other proposed equations. MATERIALS AND METHODS The study included 320 isotopic GFR measurements by 99m-T...
