BACKGROUND How to best estimate glomerular filtration rate (GFR) in kidney transplant recipients on steroid-free immunosuppression has not been established. METHODS Within 3 months of transplantation, iothalamate GFR (iGFR) was measured in 107 recipients on steroid-free and 27 on steroid-maintenance immunosuppression. A year later, a second GFR was performed. Serum creatinine was calibrated a...

Objective: An abnormal filtration fraction due to divergence between glomerular filtration rate (GFR) and effective renal plasma flow (ERPF) may lead to different estimations of absolute renal function, depending on the radiopharmaceutical administered. The purpose of this study was to estimate GFR and ERPF by measuring the clearances of technetium-99m diethylenetriamine pentaacetic acid (99mTc...

In this post hoc, secondary analysis of the Ramipril Efficacy In Nephropathy (REIN) trial, an angiotensin-converting enzyme (ACE) inhibition risk/benefit profile was assessed in 322 patients with nondiabetic, proteinuric chronic nephropathies and different degrees of renal insufficiency. The rate of GFR decline (Delta GFR) and the incidence of end-stage renal disease (ESRD) during ramipril or n...

OBJECTIVE To evaluate long-term survival, development of renal end points, and decline in glomerular filtration rate (GFR) in patients with type 2 diabetes and diabetic nephropathy (DN) after renin-angiotensin system (RAS) inhibition and multifactorial treatment of cardiovascular risk factors have become standard of care. RESEARCH DESIGN AND METHODS All patients with type 2 diabetes and DN (n...

BACKGROUND Although a reduced glomerular filtration rate (GFR) in old people has been attributed to physiologic aging, it may be associated with kidney disease or superimposed comorbidities. This study aims to assess the prevalence of decreased GFR in a geriatric population in a developing country and its prevalence in the absence of simultaneous diseases. STUDY DESIGN AND METHODS This is a c...

The aim of this study was to predict urinary creatinine excretion (UCr), creatinine clearance (CCr) and the glomerular filtration rate (GFR) from body composition analysis. Body cell mass (BCM) is the compartment which contains muscle mass, which is where creatinine is generated. BCM was measured with body impedance analysis in 165 chronic kidney disease (CKD) adult patients (72 women) with ser...

BACKGROUND/AIMS Rosiglitazone (RGL) has been used to ameliorate lipids homeostasis and also to treat inflammatory diseases. However, RGL may reduce renal blood flow and glomerular filtration rate (GFR) predisposing to acute kidney injury (AKI). We investigated whether the treatment with RGL induces AKI in normocholesterolemic (NC) and hypercholesterolemic (HC) rats. METHODS We measured GFR by...

GFR is the best indicator of renal function in children and adolescents and is critical for diagnosing acute and chronic kidney impairment, intervening early to prevent end-stage renal failure, prescribing nephrotoxic drugs and drugs cleared by a failing kidney, and monitoring for side effects of medications. Renal inulin clearance was the gold standard for GFR but is compromised by lack of ava...

BACKGROUND/AIMS We aim to investigate the extent to which depression and quality of life might be associated with decreased glomerular filtration rate (GFR) in a large hypertensive population in rural Northeast China. METHODS A total of 5566 hypertensive participants aged 35 years and older were screened with a stratified cluster multistage sampling scheme in rural areas of Liaoning Province ...

BACKGROUND AND OBJECTIVES Subclinical primary hypothyroidism is highly prevalent in the general population, especially in the elderly. However, the prevalence of subclinical primary hypothyroidism in persons with chronic kidney disease (CKD) not requiring chronic dialysis is not well defined. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS Cross-sectional data from 3089 adult outpatients, who...
