OBJECTIVE: Live kidney donation is generally viewed as a welcome treatment option for severe kidney disease. However, there is a disparity in the body of research on donor experiences and postdonation outcome, and lack of knowledge on long-term consequences described by the donors. This study was conducted to provide insight into donors' subjective meanings and interpretation of their experiences ∼10 years after donation. DESIGN: Qualitative explorative in-depth interviews...

BACKGROUND: We examined if African or Asian ethnicity was associated with lower access to kidney transplantation (KT) in a Canadian setting. METHODS: Patients referred for KT to the Toronto General Hospital from January 1, 2003 to December 31, 2012, who completed social work assessment, were included (n=1769). The association between ethnicity and the time from referral to completion of KT evaluation or receipt of a KT were examined using Cox proportional hazards models...

Autosomal dominant polycystic kidney disease (ADPKD) is the most frequent genetic cause of renal failure. Here we identify miR-17 as a target for the treatment of ADPKD. We report that miR-17 is induced in kidney cysts of mouse and human ADPKD. Genetic deletion of the miR-17∼92 cluster inhibits cyst proliferation and PKD progression in four orthologous, including two long-lived, mouse models of ADPKD. Anti-miR-17 treatment attenuates cyst growth in short-term and long-term PKD mouse models. miR-17 inhibition also suppresses proliferation and cyst growth of primary ADPKD cysts cultures derived from multiple human donors...

Increasingly, obese and overweight but healthy individuals are being considered for living donation, but the consequences of obesity on long-term health outcomes, including the risk of progression to end-stage kidney disease after donor nephrectomy, are relatively unknown. In this issue, Locke et al. analyzed a large cohort of living kidney donors in the United States, including 26% who were obese, and estimated the attributable and relative risk of end-stage kidney disease over time. Findings from this study challenge the current recommended thresholds for obesity that usually preclude donation, and inform communication regarding risk between clinicians and prospective donors during the donor evaluation process...

INTRODUCTION: The computed tomographic angiography (CTA) renal donor protocol is an established method of preoperative renal vascular pedicle evaluation in prospective renal donors. However, CTA is associated with significant radiation exposure and intravenous contrast administration. The newer noncontrast-enhanced magnetic resonance angiography (NCE-MRA) techniques, especially arterial spin labeling (ASL) with steady-state free precession (SSFP) hold promise as an effective alternative...

Patients with chronic kidney disease (CKD) display a progeric vascular phenotype linked to apoptosis, cellular senescence and osteogenic transformation. This has proven intractable to modelling appropriately in model organisms. We have therefore investigated this directly in man, using for the first time validated cellular biomarkers of ageing (CDKN2A/p16(INK4a), SA-β-Gal) in arterial biopsies from 61 CKD patients undergoing living donor renal transplantation. We demonstrate that in the uremic milieu, increased arterial expression of CDKN2A/p16(INK4a) associated with vascular progeria in CKD, independently of chronological age...

OBJECTIVES: As the demand for kidney transplant allografts has increased, many centers are expanding the upper limit of acceptable body mass index for kidney donors. However, obesity is a risk factor for developing renal disease. Our goal was to quantify body mass index trends in donor nephrectomy patients and to institute nutrition counseling to promote sustainable weight loss to reduce the risk of metabolic syndrome-derived renal dysfunction. MATERIALS AND METHODS: Ninety patients who underwent donor nephrectomy between 2007 and 2012 consented to having height and weight data collected at multiple time points...

OBJECTIVE: The aim of this study was to develop a novel chronic kidney disease (CKD) risk prediction tool for young potential living kidney donors. SUMMARY OF BACKGROUND DATA: Living kidney donor selection practices have evolved from examining individual risk factors to a risk calculator incorporating multiple characteristics. Owing to limited long-term data and lack of genetic information, current risk tools lack precision among young potential living kidney donors, particularly African Americans (AAs)...

BACKGROUND AND OBJECTIVES: Waitlist inactivity is a barrier to transplantation, because inactive candidates cannot receive deceased donor organ offers. We hypothesized that temporarily inactive kidney transplant candidates living in linguistically isolated communities would be less likely to achieve active waitlist status. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We merged Organ Procurement and Transplantation Network/United Network for Organ Sharing data with five-digit zip code socioeconomic data from the 2000 US Census...

A 54-year-old man was diagnosed with atypical haemolytic uraemic syndrome (aHUS) with confirmed complement H mutation in 2012, requiring ongoing dialysis. He was commenced on eculizumab in 2014 once the pharmaceutical board approved this drug. After 4 months, he received a live unrelated donor renal transplant from his wife and continued eculizumab post-transplant. Three months later, there was a rise in his creatinine with no laboratory features of haemolysis and a kidney biopsy confirmed rejection, which was treated with increased immunosuppression...

BACKGROUND: Two end stage renal disease (ESRD) risk calculators were recently developed by Grams et al, and Ibrahim et al to calculate ESRD risk before donation among living kidney donors. However those calculators have never been studied among potential donors for whom donation was refused due to medical contraindications and compared to a group of donors. METHODS: We compared 15-year and lifetime ESRD risk of donors and non-donors due to medical cause as estimated by those two calculators...

Donor nephrectomy in living-donor kidney transplantation may result in hyperfiltration injury in remnant kidney; however, its clinical implication in partial recovery of kidney function (PRKF) in remnant kidney and chronic kidney disease (CKD) progression remains unclear. Thus, we investigated the effect of PRKF on CKD development in the residual kidney and the utility of cystatin-C (Cys-C) in evaluating renal function in living-donor kidney transplantation donors.The electronic medical records and laboratory results of 1648 kidney transplant (KT) donors and 13,834 healthy nondonors between January 2006 and November 2014 were reviewed...

We aimed to establish a new formula for estimating renal depth, based on anthropometric variables, and to compare the estimates with actual data from a group of living kidney donors undergoing computed tomography angiography (CTA).Renal depths in 167 living kidney donors were measured by CTA. Regression analysis was used to derive the formulae for estimation of renal depth of both kidneys based on patient age, sex, body height, body weight, and body mass index (BMI). The results of the renal depth estimation from the derived formulae were compared with those using existing formulae...
