Randomized trials in adults have shown reduced all-cause and cardiovascular mortality on hemodiafiltration (HDF) compared to high-flux hemodialysis (HD), but the mechanisms leading to improved outcomes are not clear. We studied biomarkers of inflammation, oxidative stress, anti-oxidant capacity and endothelial dysfunction in 22 children (13 female, age 8-15 years). All children received HD for at least 3 months, and were then switched to HDF, keeping all dialysis related parameters and dialysis time constant...

Background: A novel in vitro test (T50 test) assesses ex vivo serum calcification propensity and predicts mortality in chronic kidney disease and haemodialysis (HD) patients. For the latter, a time-dependent decline of T50 was shown to relate to mortality. Here we assessed whether a 3-month switch to acetate-free, citrate-acidified, standard bicarbonate HD (CiaHD) sustainably improves calcification propensity. Methods: T50 values were assessed in paired midweek pre-dialysis sera collected before and 3 months after CiaHD in 78 prevalent European HD patients...

Choice of immunosuppression may modify the risk of cancer after kidney transplantation, however long-term data are lacking. Using the Australian and New Zealand Dialysis and Transplant Registry, we compared the nine-year risk of incident cancer, non-melanoma skin cancer (NMSC) and death attributed to cancer among participants, from Australia and New Zealand, in four randomised-controlled trials which compared de novo or early switch to an everolimus-containing regimen with calcineurin-inhibitor-based triple therapy...

Deoxycholate amphotericin B (d-AMB) has a higher rate of acute kidney injury (AKI) in comparison of lipid formulations. However, lipid amphotericin B has high costs in developing countries. The aim of this study is to assemble a model of cost-minimization of amphotericin B lipid complex (ABLC) in patients with cryptococcal meningitis. This is a retrospective study done in a cohort of patients with cryptococcal meningitis to study the economic impact of its use in developing countries. Cost analysis were based on direct cost of different antifungal therapies, chronic dialysis after discharge, and survival of patients based on a retrospective cohort of 102 patients infected with human immunodeficiency virus with confirmed diagnosis of cryptococcal meningitis...

Premature aging of both CD4+ regulatory T (Treg) and CD4+ responder-T (Tresp) cells in patients with end-stage renal disease (ESRD) is expected to affect the success of later kidney transplantation. Both T-cell populations are released from the thymus as inducible T-cell co-stimulator-positive (ICOS+ ) and ICOS- recent thymic emigrant (RTE) Treg/Tresp cells, which differ primarily in their proliferative capacities. In this study, we analysed the effect of ESRD and subsequent renal replacement therapies on the differentiation of ICOS+ and ICOS- RTE Treg/Tresp cells into ICOS+  CD31- or ICOS-  CD31- memory Treg/Tresp cells and examined whether diverging pathways affected the suppressive activity of ICOS+ and ICOS- Treg cells in co-culture with autologous Tresp cells...

Use of gadolinium-based contrast agents (GBCAs) in renal impairment is controversial, with physician and patient apprehension in acute kidney injury (AKI), chronic kidney disease (CKD), and dialysis because of concerns regarding nephrogenic systemic fibrosis (NSF). The position that GBCAs are absolutely contraindicated in AKI, CKD stage 4 or 5 (estimated glomerular filtration rate [eGFR] <30 mL/min/1.73 m2 ) and dialysis-dependent patients is outdated, and may limit access to clinically necessary contrast-enhanced MRI examinations...

BACKGROUND: Remote monitoring (RM) supports a healthcare model that enhances patients' self-management. We evaluated the utility of RM in patients undergoing automated peritoneal dialysis (APD). METHODS: We observed 37 -RM-APD patients, 16 incidents, and 21 prevalents switched from traditional APD (T-APD). We observed the number of changes for APD prescription, the frequency of visits, and PD adequacy parameters during 1 year of RM utilization in APD. RESULTS: The APD prescriptions were modified more frequently in RM-APD vs...

Borrelia burgdorferi ( Bb ), the agent of Lyme disease (LD), uses host-derived signals to modulate gene expression during the vector and mammalian phases of infection. Microarray analysis of mutants lacking <u>B</u>orrelia host-<u>ad</u>aptation <u>R</u>egulator (BadR) revealed down-regulation of genes encoding enzymes whose role in the patho-physiology of Bb is unknown. Immunoblot analysis of the badR mutants confirmed reduced levels of these enzymes and one of these enzymes encoded by bb0086 , shares homology to prokaryotic magnesium chelatase and Lon-type proteases...

Carnitine has high dialyzability and is often deficient in dialysis patients. This deficiency is treated by either intravenous (IV) or oral supplementation of carnitine. In this study, the mode of carnitine administration was changed from oral to IV in 17 hemodialysis (HD) patients, and the treatment was discontinued after 1 year. We found that the levels of total carnitine (TC), free-carnitine (FC), and acyl-carnitine (AC) significantly increased after 3 months of switching to IV administration (p < ...

Calciphylaxis presents with painful purpura and intractable skin ulcers on the trunk and particularly the distal extremities, and it mainly occurs in patients on chronic dialysis. A 66-year-old man with renal failure due to diabetic nephropathy was on peritoneal dialysis alone for 1 year, followed by peritoneal dialysis combined with hemodialysis for 3 years. He developed calciphylaxis of the penis, which was diagnosed from the skin biopsy findings and clinical observation. To treat this condition, PD was stopped and HD was performed three times a week...

INTRODUCTION: Bisphenol A (BPA) is an ubiquitous environmental toxin that is also found in dialyzers. Online hemodiafiltration (OL-HDF) more efficiently clears high molecular weight molecules, and this may improve BPA clearance. However, the BPA contents of dialysis membranes may be a source of BPA loading during OL-HDF. METHODS: A prospective study assessed plasma BPA levels in OL-HDF patients using BPA-free (polynephron) or BPA-containing (polysulfone) dialyzers in a crossover design with two arms, after a run-in OL-HDF period of at least 6 months with the same membrane: 31 patients on polynephron at baseline were switched to polysulfone membranes for 3 months (polynephron-to-polysulfone) and 29 patients on polysulfone were switched to polynephron for 3 months (polysulfone-to-polynephron)...

OBJECTIVES: Nocturnal haemodialysis (NHD), characterised by 8-hour sessions ≥3 times a week, is known to improve clinical parameters in the short term compared with conventional-schedule haemodialysis (HD), generally 3×3.5-4 hours a week. We studied long-term effects of NHD and used patients on conventional HD/haemodiafiltration (HDF) as controls. DESIGN: Four-year prospective follow-up of patients who switched to NHD; we compared patients with patients on HD/HDF using propensity score matching...

BACKGROUND: Recently, in the first hemodiafiltration (HDF) experience report from South East Asia (SEA), we reported a 3-year prospective study demonstrating the various short-term benefits of high-efficiency online HDF (OL-HDF) over high-flux hemodialysis (HD). Very few long-term survival reports of high-efficiency OL-HDF are available and the data are heterogeneous and incomplete. OBJECTIVES: The present historical cohort study was conducted to determine the long-term survival and outcome of high-efficiency OL-HDF-treated patients...

While an arteriovenous fistula is the best available access, many patients continue to rely on a tunneled hemodialysis catheter for dialysis therapy. Despite the highest risk of catheter-related bacteremia and associated morbidity and mortality, patients often prefer tunneled hemodialysis catheter to avoid pain associated with cannulation of an arteriovenous access. We report three tunneled hemodialysis catheter-dependent end-stage renal disease patients (age: 38, 35, 33 years), who became pregnant. Pregnancy was discovered at 10, 12 and 10 weeks of gestation...

RATIONALE: Dialysis-related amyloidosis (DRA) can present rheumatic manifestations in patients on long-term hemodialysis. Typical articular symptoms with DRA involve carpal-tunnel syndrome, effusion in large joints, spondyloarthropathy, or cystic bone lesions, which are usually with non-inflammatory processes. PATIENT CONCERNS: A 64-year-old man on hemodialysis for >30 years was admitted because of intermittent fever, polyarthritis, and elevated serum C-reactive protein (CRP) level, which was continuous for 2 years...

BACKGROUND: There is growing evidence that the accumulation of protein- bound uremic retention solutes, such as indoxyl sulfate, p-cresyl sulfate and kynurenic acid, play a role in the accelerated cardiovascular disease seen in patients undergoing chronic hemodialysis. Protein-binding, presumably to albumin, renders these solutes poor-dialyzable. We previously observed that the free fraction of indoxyl sulfate was markedly reduced at the end of hemodialysis. We hypothesized that solute binding might be pH-dependent and attributed the changes in free solute concentration to the higher serum pH observed at the end of standard hemodialysis with dialysis buffer bicarbonate concentration greater than 35 mmol/L...

EDITORIAL

Patients treated with peritoneal dialysis (PD) are often required to switch to hemodialysis (HD) temporarily when they develop abdominal wall hernias and dialysate leaks, peritonitis or undergo thoracic or abdominal surgeries. There are significant risks associated with incident hemodialysis including possible central venous catheter infections, thrombosis, and need for invasive procedures. Therefore, strategies to avoid temporary transfer to hemodialysis are desirable. The increased intra-abdominal pressure associated with PD is largely responsible for the issues requiring withholding PD...

BACKGROUND: Cardiovascular calcification (CVC) is a major concern in hemodialysis (HD) and the loss of endogenous modulators of calcification seems involved in the process. Phytate is an endogenous crystallization inhibitor and its low molecular mass and high water solubility make it potentially dialyzable. SNF472 (the hexasodium salt of phytate) is being developed for the treatment of calciphylaxis and CVC in HD patients. We aimed to verify if phytate is lost during dialysis, and evaluate SNF472's behaviour during dialysis...

BACKGROUND: Many patients in the United States have limited or no health insurance at the time they develop end-stage renal disease (ESRD). We examined whether health insurance limitations affected the likelihood of peritoneal dialysis (PD) use. STUDY DESIGN: Retrospective cohort analysis of patients from the US Renal Data System initiating dialysis therapy in 2006 through 2012. SETTING & PARTICIPANTS: We identified socioeconomically similar groups of patients to examine the association between health insurance and PD use...

BACKGROUND: The ultrasound-guided transversus abdominis plane (TAP) block has been demonstrated as a useful analgesia technique in lower-abdomen surgeries. We hypothesized that it could be the principal anesthesia technique for end-stage renal disease (ESRD) patients undergoing peritoneal dialysis (PD) catheter (PDC) implantation using the open dissection method. METHODS: This was a single-center, prospective, randomized, and double-blinded study. All eligible patients were randomized into 2 groups: the TAP block group (n = 20) and the local anesthetic infiltration (LAI) group (n = 20)...
