We designed a chemical method for measurement of iohexol concentrations (4) and characterized its pharmacokinetics in man in relation to a number of other contrast media (5, 6). We found that is indeed a suitable marker for glomerular filtration rate (GFR): after intravenous injection, it is quantitatively recovered in the urine; the elimination occurs by glomerular filtration, with no signs of...
cystatin c is a 13 kd basic protein that is a member of the cystatin superfamily of cysteine protease inhibitors. the cystatin c gene seems to be a house keeping gene, which is compatible with a stable production rate of cystatin c by most cells. this protein is freely filtered through the glomerulus and almost completely reabsorbed and catabolized by proximal tubular cells. because of these ch...
OBJECTIVE Presepsin is highlighted as a diagnostic and prognostic marker of sepsis. Little information is available regarding the accurate association between presepsin levels and the degree of kidney function. We analyzed presepsin levels in patients with a glomerular filtration rate (GFR) in the categories G1 to G5, evaluated via inulin renal clearance test, and receiving hemodialysis (HD). ...
Glomerular filtration rate (GFR) is still a highly underutilized tool in cats because available methods are not easy to be performed in clinical practice. Iohexol (IOX) has been shown to be a useful and reliable marker of GFR both in animals and in humans. The aim of the present study was to develop a rapid and reliable method for measuring IOX in feline plasma and to evaluate the accuracy of l...
BACKGROUND The determination of kidney function plays a pivotal role in living donors renal assessment because of the long-term hazards of life with one kidney. Guidelines recommend estimation of glomerular filtration rate (GFR) by the Modification of Renal Disease (MDRD) or Cockroft-Gault equations for people with normal or near-normal renal function. Cystatin C (CysC) has been introduced as a...
Accurate measurement of GFR is critical for the evaluation of new therapies and the care of renal transplant recipients. Although not accurate in renal transplantation, GFR is often estimated using creatinine-based equations. Cystatin C is a marker of GFR that seems to be more accurate than creatinine. Equations to predict GFR based on the serum cystatin C concentration have been developed, but...
BACKGROUND Serum cystatin C (sCysC) and urinary cystatin C (uCysC) are potential biomarkers for early detection of chronic kidney disease (CKD) in cats. An in-depth clinical validation is required. OBJECTIVES To evaluate CysC as a marker for CKD in cats and to compare assay performance of the turbidimetric assay (PETIA) with the previously validated nephelometric assay (PENIA). ANIMALS Nine...
BACKGROUND Glomerular filtration rate (GFR) is widely estimated by serum creatinine based equations such as Cockcroft-Gault (CG) standardized for body surface, and an abbreviated formula derived from MDRD (modification of diet in renal disease) study. However, some studies suggested that creatinine based estimation of GFR formula can be replaced by cystatin C based formula. OBJECTIVES The aim...
BACKGROUND The aim of this study was the assessment of kidney morphology and glomerular filtration rate (GFR) in rat models of polycystic kidney disease and a healthy control group of Sprague-Dawley rats (SD rats). The performance of two non-invasive GFR estimation methods-3.0 Tesla magnetic resonance imaging (MRI) and optical imaging were investigated. Data of GFR assessment was compared to su...
Diabetic and hypertensive patients gradually gets decreased glomerular function. Creatinine starts rising exhibits kidney function when more than 50% of is lost. Cystatin C, a parameter which accesses accurately predicts GFR. GFR calculated by measuring C Creatinine. Groups were normal patients, diabetics Comparison changes pre post treatment Cystatin. Total 57 patient studied 1) lower creatini...
