Differential solute clearances were used to characterize glomerular function in 12 nondiabetic subjects with severe obesity (body mass index >38). Nine healthy subjects served as the control group. In the obese group, glomerular filtration rate (GFR) and renal plasma flow (RPF) exceeded the control value by 51 and 31%, respectively. Consequently, filtration fraction increased. The augmented RPF...
The data presented in this article are related to the research article entitled "The Diagnostic Value of Rescaled Renal Biomarkers Serum Creatinine and Serum Cystatin C and their Relation with Measured Glomerular Filtration Rate" (Pottel et al. (2017) [1]). Data are presented demonstrating the rationale for the normalization or rescaling of serum cystatin C, equivalent to the rescaling of serum...
The relationships of circulating plasma volume (PV) to effective renal plasma flow and glomerular filtration rate (GFR) were investigated in reference to their interrelated changes induced by upright posture in normal subjects and patients with chronic glomerulonephritis. The following relation was obtained: (percentage change in GFR) = k(percentage change in PV). The values of k were 3.4 for t...
BACKGROUND Direct measurement of glomerular filtration rate (GFR) is the preferred method to assess renal function in cats, but it is not widely used in the diagnosis of chronic kidney disease (CKD). In cats with CKD, symmetric dimethylarginine (SDMA) has been shown to increase and to correlate with plasma creatinine concentrations. HYPOTHESIS In cats, reduced GFR corresponds with increased s...
Psammomys obesus, a desert rodent, develops diabetes when displaced from its natural environment and fed a high energy diet in the laboratory. This study was designed to examine variations in renal function in relation to the diabetic state with emphasis on changes in Na-K-ATPase activity. The following groups of Psammomys were studied: (1) Animals fed a saltbush diet; a low energy/high salt di...
Primary graft dysfunction grade correlates with acute kidney injury stage after lung transplantation
Background: Primary graft dysfunction (PGD) and acute kidney injury (AKI) are major early complications of lung transplantation associated with increased mortality. Lung after PGD can contribute to renal dysfunction; however, the association between AKI severity has not been thoroughly investigated. We analyzed grading staging, impact on subsequent changes chronic disease (CKD), including glome...
Glomerular filtration rate (GFR), renal plasma flow (RPF), and electrolyte excretion were studied in 17 patients subjected to salt depletion and loading. Salt depletion led to maximal renal salt conservation with the average GFR and RPF slightly decreased. Salt loading produced increased excretion of sodium and chloride with the average GFR and RPF slightly increased. Since the decreased electr...
As angiotensin-converting enzyme inhibition is accompanied by a marked decrease in glomerular protein loss, the hypothesis was tested that an increase of the glomerular transcapillary hydraulic pressure difference by exogenous angiotensin II would increase microalbuminuria in patients with insulin (IDDM) and non-insulin-dependent diabetes mellitus (NIDDM). Acute effects of increasing doses of a...
Previous cross-sectional transcriptomics studies have shown associations between kidney gene expression and concomitant function in patients with diabetic disease (DKD) as well other chronic (CKD) etiologies. However, of longitudinal design are lacking. We hypothesized that certain intra-renal patterns associated progressive glomerular filtration rate (GFR) decrease DKD may reveal important dri...
The size and charge-selective properties of the glomerular barrier are partly controversial. Glomerular sieving coefficients (theta) for proteins have rarely been determined noninvasively before in vivo. Therefore, theta was assessed vs. glomerular filtration rate (GFR; (51)Cr-EDTA clearance) in intact rats for radiolabeled myoglobin, kappa-dimer, neutral horseradish peroxidase (nHRP), neutral ...
