BACKGROUND Cystatin C is a new interesting marker of glomerular filtration rate (GFR). However, data regarding its biological variance are scarce and conflicting. The ability of cystatin C to longitudinally follow renal function in patients therefore remains questionable. METHODS 12 healthy subjects (6 men and 6 women) were included in the final statistical analysis. Serum creatinine, plasma ...

background: all the three nitric oxide synthase (nos) isoforms are presented in the kidney. some data provided evidences that enos activity leads to restoration of renal function after injury, but activation of inos aggravates renal failure. in the present study, we investigated that whether in gentamicin-induced renal failure selective inos blockade is beneficial. materials and methods: four g...

AIM The aim of this study was to evaluate the association between arterial stiffness and albuminuria and glomerular filtration rate (GFR) in patients with type 2 diabetes mellitus. METHODS This multicenter cohort study analyzed 2613 patients with type 2 diabetes. Brachial-ankle pulse wave velocity (baPWV) was used as a noninvasive marker of arterial stiffness. Additionally, the patients were ...

Aim. To assess the prevalence, severity and prognostic value of renal dysfunction (RD) in patients with pulmonary embolism (PE) Russian population, as well to determine RD significance a marker that improves predictive ability current risk stratification systems. Material methods. From April 2018 2019, hospitalized due PE were sequentially included multicenter observational prospective registry...

There is no simple method to measure glomerular filtration rate (GFR) in swine, an established model for studying renal disease. We developed a protocol to measure GFR in conscious swine by using the plasma clearance of iohexol. We used two groups, test and validation, with eight animals each. Ten milliliters of iohexol (6.47 g) was injected into the marginal auricular vein and blood samples (3...

The reference method to determine glomerular filtration rate (GFR) in children is the inulin clearance. Similarly, Cr51-EDTA, iohexol and iothalamate can be used as exogenous GFR markers [1,2]. Exogenous markers are expensive and rather impractical. Creatinine is by far the most commonly used biochemical marker of renal function. The commonest principle for assaying creatinine is the Jaffe reac...

Metabolomic approaches have begun to catalog the metabolic disturbances that accompany CKD, but whether metabolite alterations can predict future CKD is unknown. We performed liquid chromatography/mass spectrometry-based metabolite profiling on plasma from 1434 participants in the Framingham Heart Study (FHS) who did not have CKD at baseline. During the following 8 years, 123 individuals develo...

OBJECTIVE The aim of this study was to investigate the effect of hypo- and euthyroid status on serum cystatin C (CysC) levels in children and to explore whether CysC can be used as a marker of the thyroid status. METHODS Twenty five patients with hypothyroidism (10M, 15F; mean age:8.7±4.9 years) and 21 healhty age-matched controls (9M, 12F; mean age: 9.7±5.0 years) were included in this study...

BACKGROUND Measuring glomerular filtration rate (GFR) is an important assessment in peritoneal dialysis patients. In clinical practice, it is commonly measured by calculating the mean of the urinary clearance of urea and creatinine (GFR(UrCl)) but this process is time consuming and unreliable. We wished to compare several estimates of GFR including residual GFR estimated from cystatin C (GFR(Cy...

Renal dysfunction is a common complication for patients with heart failure, but its association with clinical outcomes has not been fully characterized. We evaluated the association of glomerular filtration rate (GFR) with heart failure survival and the effect of digoxin on heart failure outcomes across GFR strata. A secondary analysis from the Digitalis Intervention Group trial was conducted o...
