Good long-term patency: 10-year follow-up using the mid-thigh adductor loop arteriovenous graft.

Introduction: Definitive access in patients requiring renal replacement therapy is an ever-increasing challenge. For those where autogenous venous access is no longer a viable option, arteriovenous grafts can be considered. This article describes long-term follow-up, complications and patency rates of the mid-thigh 'adductor loop' arteriovenous graft.

Home hemodialysis treatment and outcomes: retrospective analysis of the Knowledge to Improve Home Dialysis Network in Europe (KIHDNEy) cohort.

Background: Utilization of home hemodialysis (HHD) is low in Europe. The Knowledge to Improve Home Dialysis Network in Europe (KIHDNEy) is a multi-center study of HHD patients who have used a transportable hemodialysis machine that employs a low volume of lactate-buffered, ultrapure dialysate per session. In this retrospective cohort analysis, we describe patient factors, HHD prescription factors, and biochemistry and medication use during the first 6 months of HHD and rates of clinical outcomes thereafter.

Outcomes of renal transplant from donors with polycystic kidney disease.

Introduction: Kidneys from donors affected by autosomal-dominant polycystic kidney disease (ADPKD) are, in general, considered unsuitable for transplantation. However, some authors report cases of patients who received kidneys from a deceased ADPKD donor showing encouraging outcomes. Our aim is to provide our experience of a patient with end stage renal failure who received a deceased donor kidney from a 29-year-old who themselves had been diagnosed with ADPKD but well maintained renal function, and to provide a comprehensive review of all the published literature.

Aneurysms in vascular access: state of the art and future developments.

A master class was held at the Vascular Access at Charing Cross (VA@CX2017) conference in April 2017 with invited experts and active audience participation to discuss arteriovenous (AV) vascular access aneurysms, a serious and common complication of vascular access (VA). The natural history of aneurysms in VA is poorly defined, and although classifications exist they are not uniformly applied in studies or clinical practice. True and pseudo aneurysms of AV access occur.

Efflux drug transporters at the forefront of antimicrobial resistance.

Bacterial antibiotic resistance is rapidly becoming a major world health consideration. To combat antibiotics, microorganisms employ their pre-existing defence mechanisms that existed long before man's discovery of antibiotics. Bacteria utilise levels of protection that range from gene upregulation, mutations, adaptive resistance, and production of resistant phenotypes (persisters) to communal behaviour, as in swarming and the ultimate defence of a biofilm.

Using a linked database for epidemiology across the primary and secondary care divide: acute kidney injury.

Background: NHS England has mandated the use in hospital laboratories of an automated early warning algorithm to create a consistent method for the detection of acute kidney injury (AKI). It generates an 'alert' based on changes in serum creatinine level to notify attending clinicians of a possible incident case of the condition, and to provide an assessment of its severity. We aimed to explore the feasibility of secondary data analysis to reproduce the algorithm outside of the hospital laboratory, and to describe the epidemiology of AKI across primary and secondary care within a region.

Intra-dialytic hypotension: Identifying patients most at risk.

Background: Intra-dialytic hypotension (IDH) remains a frequent but serious complication of haemodialysis.

Methods: We performed a retrospective observational analysis of our prevalent dialysis population extracting data from an online database.

Results: Four hundred and thirty-two patients underwent 21 consecutive outpatient dialysis sessions during the study period: Of the 9,072 dialysis sessions studied, 438 were complicated by episodes of IDH (4.

Ischemic Conditioning in Kidney Transplantation.

Ischemia-reperfusion injury is a composite of the injury sustained during a period of reduced or absent blood flow to a tissue or organ and the additional insult sustained on reperfusion, which limits the amount of tissue that can be salvaged. Ischemia-reperfusion injury is the predominant insult during kidney transplantation, contributing to graft dysfunction, increased rates of acute rejection, and reduced rejection-free graft survival. In this review, we discuss the potential therapeutic benefits of a cost-effective and low-risk intervention, ischemic preconditioning, and its potential for improving kidney function following transplantation.

Reducing the Dietary Acid Load: How a More Alkaline Diet Benefits Patients With Chronic Kidney Disease.

It has been proposed that a low-protein diet will slow progression of chronic kidney disease although studies have not always supported this belief. The accepted practice is that 60% to 70% of protein comes from high biological value (HBV) protein, but this limits patient choice and patients struggle to follow the diet. When a diet with only 30% HBV protein was trialed, there was a significant increase in serum bicarbonate, and patients preferred the diet.

Arteriovenous access ischemic steal (AVAIS) in haemodialysis: a consensus from the Charing Cross Vascular Access Masterclass 2016.

Arteriovenous access ischaemic steal (AVAIS) is a serious and not infrequent complication of vascular access. Pathophysiology is key to diagnosis, investigation and management. Ischaemia distal to an AV access is due to multiple factors.

From juvenile hyperuricaemia to dysfunctional uromodulin: an ongoing metamorphosis.

Familial juvenile hyperuricaemic nephropathy (FJHN) is a diagnosis that is easily missed. It has taken a long time to clarify the pathophysiology and prevalence of this disease entity which has been shown to be genetically identical to medullary cystic kidney disease (MCKD) type II. The initial suspicion that uric acid was the noxious agent has been replaced by the recognition that a mutant uromodulin (UMOD) is the real culprit-although the exact mechanisms of pathogenicity remain uncertain.

Collagen (COL4A) mutations are the most frequent mutations underlying adult focal segmental glomerulosclerosis.

Background: Multiple genes underlying focal segmental glomerulosclerosis (FSGS) and/or steroid-resistant nephrotic syndrome (SRNS) have been identified, with the recent inclusion of collagen IV mutations responsible for Alport disease (AD) or thin basement membrane nephropathy (TBMN). We aimed to investigate the distribution of gene mutations in adult patients with primary FSGS/SRNS by targeted next generation sequencing (NGS).

Methods: Eighty-one adults from 76 families were recruited; 24 families had a history of renal disease.
