Background/Aims. Renal impairment is a common complication of cirrhosis. Serum creatinine is less sensitive in these patients. Measurement of the glomerular filtration rate (GFR) is the gold standard but time consuming. The aim is to validate plasma NGAL (pNGAL) and urinary NGAL (uNGAL) as markers of renal function in patients with HCV related cirrhosis. Patient and Methods. One hundred HCV rel...

STIFFLER, DANIEL F., AND RONALD H. ALVARADO. Rena/function in response to reduced osmotic load in larval salamanders. Am. J. Physiol. 226(5) : 1243-l 249. 1974.-Renal function was studied in larval Ambystoma gracile and Dicamptodon ensatus exposed to several osmoh&ties. Clearance methods were employed in free-swimming larvae using inulin as a GFR marker. GFR, as calculated from the rate of appe...

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...

Objective: Chronic kidney disease (CKD) and diabetes mellitus can influence coronary artery disease (CAD) independently. The aim of this study was to evaluate the association of glomerular filtration rate (GFR) and CAD in type 2 diabetic patients (T2DM). Materials and Methods: This cross sectional study evaluated 3624 T2DM patients with clinical presentation of CAD whose documents were registe...

BACKGROUND Patients with anorexia nervosa (AN) are at a high risk of renal failure. Chronic kidney disease (CKD) is often missed in these patients because the serum creatinine is a poor marker of kidney function. We studied the utility of cystatin C to detect renal failure in this population. METHOD Twenty-seven AN patients were studied. Glomerular filtration rates (GFR) were measured with th...

BACKGROUND/AIMS Adults with congenital heart disease exhibit a 3-fold higher mortality in the presence of chronic kidney disease, hence assessment of renal function is crucial in this patient population. Formulas for the estimation of glomerular filtration rate (GFR) have not been evaluated in this patient population. Therefore, this study compares different markers and equations for the estima...

Renal sonographic findings can now be implicated for prediction of changes in Glomerular filtration rate, and estimation of the degree of renal dysfunction in pets. This was successfully determined during a 20-day chronic unilateral ureteral obstruction in experimental dogs. GFR was quantitatively measured following a single intravenous bolus of inulin. The total clearance of the marker was cal...

BACKGROUND The aim of the present study was to compare the most commonly used GFR markers for clearance measurements, 51Cr-EDTA and iohexol, using two different methods for iohexol analysis, HPLC and X-ray fluorescence, referring both to the multiple-sample and single-sample calculations, using 51Cr-EDTA as the reference method. METHODS Forty-nine patients with an estimated GFR >40 ml/min wer...

To the Editor: Iohexol is regarded as an accurate filtration marker for measuring GFR. Recently, Soveri et al concluded that plasma clearance of iohexol could be considered a valid alternative to the gold standard, urinary clearance of inulin. Because inulin urinary clearance is cumbersome and costly, iohexol and iothalamate clearance have become popular in Europe and the United States, respect...

BACKGROUND Chronic kidney disease (CKD) is a worldwide public health problem. Glomerular filtration rate (GFR) is accepted as the best way to diagnose and monitor kidney function. Plasma Cystatin C (CysC) has been proposed as a better marker of GFR than serum creatinine (SCr), but it is not widely used because of some drawbacks with CysC assays. Our purpose is to determine the diagnostic accura...
