Early glomerular filtration rate changes in living kidney donors and recipients: an example of renal plasticity.

Background: In living kidney transplantation there are two different individuals, a healthy donor and a renal transplant recipient. This is an excellent human model to study factors that influence kidney function in the context of reduced renal mass and the adaptation of two comparable kidneys to different metabolic demands.

Methods: We analyzed the changes in measured glomerular filtration rate (GFR, iohexol) from pretransplantation to 12 months after transplantation in 30 donor-recipient pairs.

Management of Kidney Failure in Patients with Diabetes Mellitus: What Are the Best Options?

Diabetic kidney disease (DKD) is the most frequent cause of kidney failure (KF). There are large variations in the incidence rates of kidney replacement therapy (KRT). Late referral to nephrology services has been associated with an increased risk of adverse outcomes.

Impact of errors of creatinine and cystatin C equations in the selection of living kidney donors.

Background: Reliable determination of glomerular filtration rate (GFR) is crucial in the evaluation of living kidney donors. Although some guidelines recommend the use of measured GFR (mGFR), many centres still rely on estimated GFR (eGFR) obtained through equations or 24-h creatinine clearance. However, eGFR is neither accurate nor precise in reflecting real renal function.

Frailty in hemodialysis and prediction of poor short-term outcome: mortality, hospitalization and visits to hospital emergency services.

Frailty is an aging-associated state of increased vulnerability, which raises the risk of adverse outcomes. Chronic kidney disease is associated with higher prevalence of frailty. Our aim was to estimate frailty prevalence in a hemodialysis population and its influence on short-term outcomes.

Erratum: Impact of errors of creatinine and cystatin C equations in the selection of living kidney donors.

Renal replacement therapy in the Canary Islands: demographic and survival analysis.

Background: The continuous increase in the number of patients on renal replacement therapy (RRT) has heightened the importance of renal patient registries to respond to the demand for data on the state of health, quality and cost of care provided for these patients. Our aim was to analyze the epidemiological profile of this population in the Canary Islands.

Methods: All patients on RRT between January 1999 and December 2003 were considered in this analysis.

Prevalence, clinical correlates and therapy cost of mineral abnormalities among haemodialysis patients: a cross-sectional multicentre study.

Background: This study evaluated the proportion of patients who met National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF-K/DOQI) guidelines for mineral status, and assessed the cost of therapy for mineral management of patients under haemodialysis treatment in Spain.

Methods: Demographic and biochemical data were collected for 1312 patients undergoing standard three-times weekly maintenance haemodialysis at six Spanish centres during December 2003. Age, gender, diabetic nephropathy, haemodialysis duration, serum calcium, phosphorus, calcium-phosphorus product (Ca x P), and intact parathyroid hormone (iPTH) levels were monitored.
