More than half of deaths in end-stage kidney disease (ESKD) patients are due to cardiovascular disease. Elevated fibroblast growth factor 23 (FGF-23) was found to be associated with mortality in hemodialysis (HD) patients and correlates with peripheral calcification. Aortic calcification is associated with coronary artery calcification. Both aortic and peripheral vascular calcifications were associated with mortality in chronic kidney disease. We aimed to investigate the relation between intact FGF-23 and cardiovascular calcification in patients with ESKD who were maintained on regular HD...

Renal fibrosis is the common pathological hallmark of progressive chronic kidney disease (CKD) with diverse aetiologies. Recent researches have highlighted the critical role of hypoxia during the development of renal fibrosis as a final common pathway in end-stage kidney disease (ESKD), which joints the scientist's attention recently to exploit the molecular mechanism underlying hypoxia-induced renal fibrogenesis. The scaring formation is a multilayered cellular response and involves the regulation of multiple hypoxia-inducible signalling pathways and complex interactive networks...

BACKGROUND: Approximately 500,000 people in the United States are affected by end-stage kidney disease (ESKD), 53% of whom are Black or Latino. ESKD significantly impacts psychosocial health and quality of life. However, few studies address the psychosocial aspects of ESKD, especially among black and Latino adults. This study sought to understand the psychosocial context of living with ESKD among black and Latino adults who reside in a medically underserved community. STUDY DESIGN: A qualitative study...

Chronic kidney disease (CKD) affects 8-16% of adults worldwide and is associated with multiple adverse outcomes. It includes a heterogeneous group of conditions with widely varied associated risks; risk stratification is therefore vital for clinical management. Use of the CKD Epidemiology Collaboration (CKD-EPI) equation to estimate glomerular filtration rate (GFR) instead of the Modification of Diet in Renal Disease (MDRD) equation will reduce, though not eliminate, over-diagnosis of CKD. Cystatin C is recommended as an alternative measure of GFR but is not yet widely used...

Conventional diffusion-based dialysis modalities including high-flux hemodialysis are limited in their capacity to effectively remove large uremic toxins and to improve outcomes for end-stage chronic kidney disease (ESKD) patients. By increasing convective solute transport, hemodiafiltration (HDF) enhances solute removal capacity over a broad range of middle- and large-size uremic toxins implicated in the pathophysiology of chronic kidney disease. Furthermore, by offering flexible convection volume, on-line HDF permits customizing the treatment dose to the patient's needs...

BACKGROUND: Identification of patients at risk of developing adverse events would enable aggressive medical therapy and possibly targeted revascularization. The aim of this study is to characterize the determinants of long-term outcomes in atherosclerotic renovascular disease (ARVD). METHODS: Patients with a radiological diagnosis of ARVD were recruited into this single-center prospective cohort study between 1986 and 2014. Data collected included baseline co-morbid conditions, annualized prescribed medications and laboratory data (serum creatinine [υmol/L], proteinuria [g/24 h])...

Living donor kidney transplantation (LDKT) is the optimal treatment for end-stage kidney disease (ESKD). The evaluation process for a kidney transplant is complex, time consuming, and burdensome to the ESKD patient. Also, race disparities exist in rates of transplant evaluation completion, transplantation, and LDKT. In December 2012 our transplant center implemented a streamlined, one-day evaluation process, dubbed Kidney Transplant Fast Track (KTFT). This paper describes the protocol of a two-part study to evaluate the effectiveness of KTFT at increasing transplant rates (compared to historical controls) and the TALK intervention (Talking About Live Kidney Donation) at increasing LDKT during KTFT...

INTRODUCTION: Alport syndrome is an inherited renal disease characterized by hematuria, renal failure, hearing loss and a lamellated glomerular basement membrane. Patients with Alport syndrome who undergo renal transplantation have been shown to have patient and graft survival rates similar to or better than those of patients with other renal diseases. METHODS: In this national case series, based in Beaumont Hospital Dublin, we studied the cohort of patients who underwent renal transplantation over the past 33 years, recorded prospectively in the Irish Renal Transplant Registry, and categorized them according to the presence or absence of Alport syndrome...

Primary hyperoxaluria type 1 (PH1) is a rare, autosomal recessive disease, caused by the defect of AGXT gene encoding hepatic peroxisomal alanine glyoxylateaminotransferase (AGT). This enzyme is responsible for the conversion of glyoxylate to glycine. The diagnosis of PH1 should be suspected in infants and children with nephrocalcinosis or nephrolithiasis. Early diagnosis and treatment is crucial in preventing disease progression to end stage kidney disease (ESKD). In this study, AGXT gene sequence analyses were performed in 82 patients who were clinically suspected (hyperoxaluria and nephrolithiasis or nephrocalcinosis with or without renal impairment) to have PH1...

BACKGROUND: The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation that combines creatinine and cystatin C is superior to equations that include either measure alone in estimating glomerular filtration rate (GFR). However, whether cystatin C can provide any additional benefits in estimating GFR for Indigenous Australians, a population at high risk of end-stage kidney disease (ESKD) is unknown. METHODS: Using a cross-sectional analysis from the eGFR Study of 654 Indigenous Australians at high risk of ESKD, eGFR was calculated using the CKD-EPI equations for serum creatinine (eGFRcr), cystatin C (eGFRcysC) and combined creatinine and cystatin C (eGFRcysC+cr)...

The prevalence of diabetes around the world has reached epidemic proportions and is projected to increase to 642 million people by 2040. Diabetes is already the leading cause of end-stage kidney disease (ESKD) in most developed countries, and the growth in the number of people with ESKD around the world parallels the increase in diabetes. The presence of kidney disease is associated with a markedly elevated risk of cardiovascular disease and death in people with diabetes. Several new therapies and novel investigational agents targeting chronic kidney disease patients with diabetes are now under development...

The combination of dabrafenib and trametinib is a standard of care for the management of BRAF mutant metastatic melanoma. Clinical trials excluded patients with end-stage kidney disease (ESKD) and as such no data are available regarding the safety, efficacy and pharmacokinetics of these drugs in such patients. Here, we present the case of a 78 year-old male patient with ESKD managed with haemodialysis (HD), treated with dabrafenib and trametinib at reduced doses. The patient has had a partial response, and this response continues at 9 months since our last follow up without any dose escalation...

AIM: Podocyte depletion in the kidney is associated with end-stage kidney disease (ESKD). Pre-eclampsia (PE) increases the risk of ESKD in later life. This study was performed to determine whether nephrinuria (soluble nephrin in the urine) is correlated with proteinuria and/or podocyturia (podocytes in the urine) in PE women. METHODS: Eighty-three urine samples, consisting of 45 and 38 samples from 27 normotensive and nine PE women, respectively, underwent simultaneous determination of nephrin, protein, and creatinine concentrations in the urine supernatant and quantitative analysis of podocyte-specific protein mRNA expression...

BACKGROUND/OBJECTIVES: Iron and phosphate are both vital to many biological cellular processes with central roles in energy metabolism, cellular proliferation and nucleic acid synthesis. Regulatory pathways in some of these metabolic pathways may intersect at fibroblast growth factor 23 (FGF23), a major phosphate regulatory hormone. Iron is reported to induce hypophosphataemia in rare cases, and recent reports suggest that iron deficiency may upregulate FGF23 synthesis by mechanisms involving hypoxia-inducible factor 1α (HIF1α)...

The presence of chronic kidney disease (CKD) is a strong risk factor not only for end stage kidney disease (ESKD) but also cerebro-cardiovascular disease (CVD). CKD is defined as GFR < 60ml/min/1.73m and/or the evidence of renal damages for more than 3 months. Epidemiological studies have shown that albuminuria even as little as 10mg/gCr is a strong risk factor for CVD, especially stroke. The significance of albuminuria can be recognized when we think of the fact that the amount of albumin in 24 hour-GFR is as large as 6 kg (4...

BACKGROUND: Many patients with end-stage kidney disease (ESKD) have significant psychosocial needs as a consequence of their illness and treatment. Unmet needs can impact negatively on their health and well-being. Patients want improved psychosocial support particularly in relation to coping and adjustment. Little is known about the relevance and applicability to patients of intervention approaches to support their psychosocial needs. OBJECTIVES: To explore patients' attitudes to different intervention approaches that could be developed to help them cope with the psychosocial stressors of ESKD, and to assess the potential acceptability of these approaches...

OBJECTIVE: We explored the nerve ultrasound (US) characteristics of 15 patients with end-stage kidney disease (ESKD) and correlated these findings with clinical severity and electrophysiological parameters of neuropathy. METHODS: 15 ESKD patients on thrice-weekly high-flux haemodialysis and 15 healthy controls were enrolled. Sonographic and electrophysiologic studies were conducted before and after a single session of haemodialysis. Serial measurements of median nerve cross-sectional area (CSA) and hypoechoic fraction (HF) were performed at the same non-entrapment site in the mid-forearm...
