Hemodiafiltration

Although pregnancy has become more frequent in patients undergoing hemodialysis, it remains a relatively rare event and carries a high risk of complications for both the mother and the fetus. In parallel, multiple pregnancies are also associated with a high risk of complications for the mother and the fetus, even in healthy women. The presence of a twin pregnancy in a woman with chronic renal failure undergoing hemodialysis is an even rarer event and is considered a very high-risk situation. We describe the case of a 31-year-old hemodialysis patient who successfully gave birth to twins at 29 weeks after a period of alternate diurnal and nocturnal hemodialysis...

Despite significant medical and technical improvements in the field of dialysis, the morbidity and mortality among patients with chronic kidney disease (CKD) stage 5 on dialysis remains extremely high. Hemodiafiltration (HDF), a dialysis method that combines the two main principles of hemodialysis (HD) and hemofiltration-diffusion and convection-has had a positive impact on survival when delivered with a high convective dose. Improved outcomes with HDF have been attributed to the following factors: HDF removes middle molecular weight uremic toxins including inflammatory cytokines, increases hemodynamic stability, and reduces inflammation and oxidative stress compared to conventional HD...

There has been a wealth of new developments in dialysis this year with the publication of several trials relating to dialysis technique, physical activity and the use of new dialysis treatments. Quality of life should be assessed and managed in all dialysis patients. Lowering the temperature of the dialysis bath in the MyTemp trial does not appear to have an effect on mortality and cardiovascular events. High volume convective hemodiafiltration currently represents the reference technique in hemodialysis; the Convince study confirms its superiority in terms of all-cause mortality...

Background: Tolvaptan sodium phosphate (Samtas® ; Otsuka Pharmaceutical, Tokyo, Japan) is a novel intravenous aquaretic diuretic aimed at individuals experiencing advanced congestion refractory to conventional diuretics and having difficulty with oral intake. Despite its potential, the true efficacy and practicality of this compound within real-world clinical settings remain obscure. Methods: A retrospective analysis of clinical data was conducted, examining trends among consecutive in-hospital patients diagnosed with congestive heart failure who underwent treatment with tolvaptan sodium phosphate at a prominent academic medical center between June 2022 and June 2023...

The purpose of blood purification therapy is to remove uremic toxins, and middle molecules (MMs) are a specific target. An MM is defined as a solute that passes through the glomerulus with a molecular weight in the range of 0.5-58 kDa, and new classifications of "small-middle 0.5-15 kDa," "medium-middle 15-25 kDa," and "large-middle 25-58 kDa" were proposed. In Japan, the removal of α1-microglobulin (αMG) in the large-middle range has been the focus, but a new theory of removal has been developed, emphasizing the antioxidant effect of αMG as a physiological function...

INTRODUCTION: To explore the effect of CRRT using CVVHDF + HP on the removal of inflammatory mediators in patients with septic shock complicated with AKI. METHODS: A total of 20 patients between January 1, 2018, and December 31, 2021, were included. The patients were randomly divided into the treatment group (CVVHDF + HP) and the control group (CVVHDF). Changes in inflammatory factors, including IL-1β, IL-6, IL-8, TNF-α, PCT, and CRP were compared...

INTRODUCTION: Recent advances in dialysis therapy have made it possible to remove middle molecules. Removal of small-middle molecules, such as β2-microglobulin (BMG), can now be achieved with conventional hemodialysis, and removal of large-middle molecules has become a target, particularly for 1-microglobulin (AMG, 33 kD). The AMG reduction rate has emerged as a target for improvement of various clinical symptoms, but the effects on prognosis have yet to be determined. The "Japanese study of the effects of AMG (α1-microglobulin) reduction rates on survival" (JAMREDS) was started in April 2020, with the goal of determining if the AMG reduction rate associates with the risk of mortality and cardiovascular disease (CVD) events...

INTRODUCTION: To analyze the clinical efficacy and long-term prognosis of high flux hemodialysis (HFHD) combined with different frequency hemodiafiltration (HDF) in uremic patients. METHODS: 86 middle-aged and elderly patients with uremia were divided into the HF group (HFHD combined with high-frequency HDF) and the LF group (HFHD combined with low-frequency HDF). The changes between the two groups in various indicators after 12 months of dialysis and the survival rate at 5 years of follow-up were compared...

The CONVINCE trial demonstrates that high-dose hemodiafiltration offers a survival advantage for patients in the high-flux hemodiafiltration group compared to hemodialysis. We compared the outcomes of hemodialysis and hemodiafiltration using real-world data. We conducted an analysis on a cohort of patients who underwent hemodiafiltration therapy (HDF) at a single center, NefroStar Clinics. The results obtained were then compared with data from patients receiving hemodialysis (HD) therapy within the Brazilian Public Health System (SUS)...

There are several forms of maintenance high-efficiency hemodialysis (HD), including hemodiafiltrations (HDF) in different technical modes and expanded HD, using dialyzers with medium cut-off membranes. The aim of the study was to assess the intradialytic tolerance and length of dialysis recovery time (DRT) in these modalities. This is an exploratory, crossover study in maintenance HD patients with low comorbidity and no clinical indications for the use of high-efficiency HD, who were exposed to five intermittent dialyses in random order: high-flux hemodialysis (S-HD), expanded HD (HDx), pre-dilution HDF (PRE-HDF), mix-dilution HDF (MIX-HDF) and post-dilution HDF (POST-HDF)...

Molecules such as sparsentan and budesonide look promising to treat proteinuric IGA nephropathy. SLGT2 inhibitors have a prominent place in nephroprotection and could be used in the treatment of acute kidney injury due to heart failure as well. High volume hemodiafiltration compared to hemodialysis improves survival in dialysis patients. Lessening dialysate temperature does not improve hemodynamic stability during the dialysis session. Sodium bicarbonate does not seem to protect renal function in renal transplant patients...

Dialysis therapy has remarkably evolved through the innovation in dialyzers and hemodialysis modalities, enhancing patients' quality of life. The efficacy of dialysis can be determined by measuring the reduction ratio (RR) of middle molecules such as Interleukin-6 (IL-6) and Procalcitonin. In our study, we tested a high-flux dialyzer, BIOPURE (Biorema) 260 HF, with a surface area (SA) of 2.6 m2, in terms of IL-6 and Procalcitonin removal while performing high-flux hemodialysis (HF-HD) and post-dilution online hemodiafiltration (OL-HDF)...

BACKGROUND: While troponin is an established biomarker of cardiac injury, its prognostic significance in post-cardiotomy cardiogenic shock patients supported by venoarterial extracorporeal membrane oxygenation (PCCS-VA-ECMO) remains unclear. OBJECTIVE: This study aimed to assess the correlation between early post-operative troponin T levels and both short-term and long-term mortality outcomes in this cohort. METHODS: We evaluated 1457 troponin T measurements from 102 PCCS-VA-ECMO patients treated from 2013 to 2018 at a specialized cardio-surgical and transplantation center...

BACKGROUND: Citrate dialysate (CD) has been successfully used in conventional hemodialysis and continuous renal replacement therapy; however, no study has compared pre- and post-dilution online hemodiafiltration (oL-HDF). Therefore, we aimed to investigate the efficacy of citrate anticoagulation for oL-HDF and the metabolic changes and quality of life of patients on hemodialysis treated using both modes. METHOD: Eight dialysis patients were treated with CD containing 0...

Hemodiafiltration with endogenous reinfusion of the ultrafiltrate (HFR) is a dialysis technique characterized by a resin cartridge with adsorptive properties that combines the mechanisms of diffusion, convection, and adsorption in a single therapeutic regimen. After nearly 20 years of clinical experience with HFR, this article reviews the accumulated evidence with this technique, considering whether adsorption reduction, as a third purification mechanism, should be the next step in the treatment of hemodialysis patients...

Patients with end stage kidney disease treated by dialysis (ESKDD) process dialysis sessions to remove molecules usually excreted by kidneys. However, dialysis therapy could also contribute to endocrine disruptors (ED) burden. Indeed, materials like dialyzer filters, ultrapure dialysate and replacement fluid could exposed ESKDD patients to Bisphenol A (BPA) and chlorinated derivatives of BPA (ClxBPAs). Thus, our aim was to compare BPA and ClxBPAs exposure between ESKDD patients, patients with stage 5 chronic kidney disease (CKD5) not dialyzed and healthy volunteers...

Case Report C.S.T. (♂, 71 years old) is a patient with multiple and severe comorbidities, undergoing thrice-weekly chronic hemodialysis since 2008 due to the progression of post-lithiasic uropathy. Over the past 2 months, the patient had been experiencing progressive ptosis of the eyelids, muscle weakness, and ultimately dysphagia and dysarthria that emerged in the last few days. Urgently admitted to the Neurology department, electromyography (EMG) was performed, leading to a diagnosis of predominant cranial myasthenia gravis (with borderline anti-acetylcholine receptor antibody serology)...
