BACKGROUND/AIMS: Little information is available about the tubular functions and the renal adjustments that take place in obese subjects after a protein meal. How the excess fat may affect renal response to dietary proteins is currently only partially understood. This paper aims to address (i) whether severe obesity, in the absence of other comorbidities, is responsible of kidney dysfunction at either the glomerular or the tubular level and (ii) whether it compromises renal adaptations to a large protein meal...

Hypertension and chronic kidney disease (CKD) have a significant impact on global morbidity and mortality. The Low Birth Weight and Nephron Number Working Group has prepared a consensus document aimed to address the relatively neglected issue for the developmental programming of hypertension and CKD. It emerged from a workshop held on April 2, 2016, including eminent internationally recognized experts in the field of obstetrics, neonatology, and nephrology. Through multidisciplinary engagement, the goal of the workshop was to highlight the association between fetal and childhood development and an increased risk of adult diseases, focusing on hypertension and CKD, and to suggest possible practical solutions for the future...

BACKGROUND: Puumala virus (PUUV)-induced hemorrhagic fever with renal syndrome is common in many European countries. The typical renal histologic lesion is acute tubulointerstitial nephritis. We examined the type and kinetics of urine protein excretion and prognostic significance of proteinuria for the severity of acute kidney injury (AKI) in acute PUUV infection. METHODS: The amount of dipstick albuminuria at hospital admission was analyzed in 205 patients with acute PUUV infection...

BACKGROUND: Low bone mineral density (BMD) is a known independent predictor of mortality in the general elderly population. However, studies in patients with end-stage renal disease (ESRD) are limited. The present study evaluated mortality during long-term follow-up in a population of patients having dialysis for ESRD, in whom BMD was also measured. METHODS: Fifty-eight patients with ESRD were recruited consecutively from a dialysis clinic and followed prospectively for 6 years...

BACKGROUND: Depression is the most common mental health disorder among those with end-stage renal disease (ESRD), with prevalence of 15-40%. However, the association between chronic kidney disease (CKD) and depression is more variable. We examined the associations of CKD with depression, perceived health status, and quality of life in the National Health and Nutrition Examination Survey (NHANES) 2011-2012. METHODS: This study included 4,075 adults. Depression was defined as a condition when a Patient Health Questionnaire score was ≥10, or when there was reported antidepressant use...

BACKGROUND: Chronic kidney disease (CKD) patients who experience superimposed acute kidney injury (AKI) have been shown to be at higher risk of long-term sequelae of AKI when compared to those who do not experience AKI. It remains unclear whether the need for temporary dialysis intervention following superimposed AKI in patients with CKD has any effect on the long-term major adverse cardiovascular events (MACE). This study examines the relationship between temporary dialysis therapy following AKI and long-term major cardiovascular events in patients with background CKD...

Alport syndrome (AS) is a disorder of collagen IV, a component of glomerular basement membrane (GBM). The association of AS and immunocomplex nephropathies is uncommon. This is a case of a 37-year-old woman with family history of X-linked AS, including 4 affected sons. This patient developed full-blown nephrotic syndrome along a 3-month period, a presentation not consistent with AS progression. This scenario suggested an alternative diagnosis. A kidney biopsy was therefore performed, showing membranous nephropathy (MN) in addition to GBM structural alterations compatible with AS...

BACKGROUND/AIMS: Fatigue is recognised as a common and burdensome symptom among dialysis patients. A growing body of research is devoted to understanding fatigue in advanced kidney disease, yet its measurement is challenging within this context. Our aim was to evaluate the factor structure underlying the multidimensional fatigue inventory (MFI-20) and to examine its associations with clinical factors and mood. METHODS: Data was evaluated for confirmatory factor analysis (CFA) from the screening phase of a multicentre randomised placebo-controlled trial of sertraline in haemodialysis (HD) patients...

BACKGROUND: The prevalence of subclinical atherosclerosis and the main predictors of progression of this condition in patients undergoing peritoneal dialysis (PD) have been insufficiently investigated. OBJECTIVES AND METHOD: Following a prospective, multicenter, observational design, we studied 237 patients who were treated with PD for ≥3 months, without any clinical background of cardiovascular (CV) disease. Our objectives were the following: (1) to investigate the prevalence of subclinical atherosclerosis, as compared to a control group of age- and sex-matched healthy individuals, and (2) to disclose PD technique-related predictors of progression of disease during a 24-month follow-up period...

BACKGROUND: Best practice in dialysis is synthesised in clear international guidelines. However, a large gap remains between the international guidelines and the actual delivery of care. In this paper, we report outcomes for the first year of a multifaceted dialysis improvement programme in our network. METHODS: One year collaborative involving 3 haemodialysis units and a peritoneal dialysis (PD) programme involving 299 dialysis patients. Each unit addressed a different indicator (unit A - catheter-related bloodstream infection [CRBSI], unit B - pre-dialysis blood pressure [BP], unit C - dialysis dose, unit D - anaemia) with a shared aim to match the top 10% in the UK...

BACKGROUND/AIMS: Few studies explore the magnitude of the disease burden and health care utilization imposed by renal disease among patients with hepatitis C virus (HCV). We aimed to describe the characteristics, outcomes, and health care utilization and costs of patients with HCV with and without renal impairment. METHODS: This retrospective analysis used 2 administrative claims databases: the US commercially insured population in Truven Health MarketScan® data (aged 20-64 years), and the US Medicare fee-for-service population in the Medicare 20% sample (aged ≥65 years)...

Drug dosing in accordance with the renal function is a long-standing challenge to clinicians. For many years it has been evident that in many clinical situations there is no easy way to correctly dose any drug that is mainly cleared by the kidneys. Despite the development of many formulas for estimating the glomerular filtration rate, they all have serious shortcomings. Much effort has been put in to develop estimation formulas to evaluate the renal function as an alternative to direct methods with the aim of safely dosing drugs that are mainly cleared by the kidneys...

Berthold Hocher, Lianghong Yin
Preclinical studies in cell culture systems as well as in whole animal chronic kidney disease (CKD) models showed that parathyroid hormone (PTH), oxidized at the 2 methionine residues (positions 8 and 18), caused a loss of function. This was so far not considered in the development of PTH assays used in current clinical practice. Patients with advanced CKD are subject to oxidative stress, and plasma proteins (including PTH) are targets for oxidants. In patients with CKD, a considerable but variable fraction (about 70 to 90%) of measured PTH appears to be oxidized...

BACKGROUND/AIMS: In our earlier studies, we reported high concentrations of intra- and extracellular calcium ions (Ca2+) in the deeper epidermis of patients with chronic kidney disease (CKD) and associated pruritus. To determine the cause of this phenomenon, we measured total calcium (TCa) concentrations in the deeper epidermis and performed immunostaining of epidermal albumin, which binds to Ca2+. METHODS: This study included 45 patients with CKD-stage 5, which was defined as severely reduced kidney function (i...

BACKGROUND: In the United Kingdom, socioeconomic disadvantage has been associated with lower use of home dialysis, mostly peritoneal dialysis. In this study, we explore the role of a patient's sociodemographic, socioeconomic differences and the centre's influence on home haemodialysis (HD) prevalence. METHODS: Data is derived from the cross-sectional arm of the UK multi-centre study investigating barriers and enablers of home HD (BASIC-HHD study). Centres were classified as low- (<3%), medium- (5-8%) and high-prevalence groups (>8%)...

BACKGROUND: N-linked glycosylation, which is a post-translational modification process, plays an important role in protein folding, intracellular trafficking and membrane targeting, as well as in regulating the protein function. Recently, we identified a missense variant (p.T141L) in the short isoform 2 of the X-linked gene asparagine-linked glycosylation 13 (ALG13-is2), which segregated with focal segmental glomerulosclerosis and PCCD in a large Australian pedigree; however, any evidence of its pathogenicity was demonstrated...
