A study of glomerular filtration rate estimation by cockcroft-gault, mdrd and ckd-epi formula in comparison with dtpa renal scan – a comparative study among live related kidney donors in south india. a b c Original Article BACKGROUND: Renal function assessment is the most important part of donor evaluation. The Glomerular Filtration Rate (GFR) is considered to be optimal test for overall assess...

We assessed 1-year outcomes in patients with atrial fibrillation enrolled in the EurObservational Research Programme AF General Pilot Registry (EORP-AF), in relation to kidney function, as assessed by glomerular filtration rate (eGFR). In a cohort of 2398 patients (median age 69 years; 61% male), eGFR (ml/min/1.73 m(2)) calculated using the CKD-EPI formula was ≥80 in 35.1%, 50-79 in 47.2%, 30-4...

The prevalence of kidney disease, particularly diabetic and hypertensive kidney disease is increasing rapidly specially in the disadvantageous group of population throughout the world. A cross sectional survey was carried out at certain selected slum areas of Mirpur in Dhaka city of Bangladesh over the period from July 2003 to June 2005, and a total of participants ranging from 15 to 65 years w...

BACKGROUND For the estimation of renal function on the basis of serum creatinine, either the Cockcroft-Gault (CG) equation or the MDRD formula is commonly used. Compared to MDRD (using power functions), CG has the advantage of easy calculability at the bedside. MDRD, however, approaches glomerular filtration rate (GFR) more precisely than CG and gives values corrected for a body surface area (B...

Background Rapid and accurate estimation of the glomerular filtation rate (GFR) is required for many major clinical decisions in patients with chronic nephropathies [1]. Direct GFR measurement is time-consuming and expensive, frequently requires urine collection and isotope use, and is routinely available in only a few medical centers [1]. In clinical practice, GFR is usually estimated from the...

AIM To compare the performance of iohexol plasma clearance and creatinine-based renal function estimating equations in monitoring longitudinal renal function changes in chronic heart failure (CHF) patients, and to assess the effects of body composition on the equation performance. METHODS Iohexol plasma clearance was measured in 43 CHF patients at baseline and after at least 6 months. Simulta...

OBJECTIVE to analyze the effect of the modifications in the Cockcroft-Gault equation for creatinine clearance rate determination (CrCl) and its concordance with the real value determined from 24-hours urine collection in a sample of Latin American patients hospitalized in San José de Costa Rica. METHOD an observational, retrospective study, with patients submitted to a 24-hour urine collectio...

BACKGROUND Although prediction equations are recommended to determine GFR and creatinine clearance (CrCl), neither the MDRD equations nor the Cockcroft and Gault formula have been validated for the low levels of GFR present in end-stage renal disease (ESRD). The accuracy of the MDRD equations and the Cockcroft and Gault formula in predicting GFR and CrCl, respectively, was examined in patients ...

INTRODUCTION Arterial hypertension is a worldwide public health problem and one of the major risk factors for chronic kidney disease development. METHODS In order to compare the Cockcroft-Gault (CG) equation with serum creatinine and 24-hour creatinine clearance (CrCl) for the screening of reduced renal function, a cross-sectional study of 198 hypertensive patients was undertaken at a basic h...

BACKGROUND In critically ill patients with acute kidney injury, estimates of kidney function are used to modify drug dosing, adjust nutritional therapy and provide dialytic support. However, estimating glomerular filtration rate is challenging due to fluctuations in kidney function, creatinine production and fluid balance. We hypothesized that commonly used glomerular filtration rate prediction...
