Haemodiafiltration

INTRODUCTION: Haemodialysis is the most common treatment option for patients with life-sustaining end-stage kidney disease (ESKD). In recent years, haemodiafiltration or haemofiltration has been widely used in patients with ESKD, and there are still conflicting findings as to whether both are superior to traditional haemodialysis. This systematic review and meta-analysis were designed to determine whether haemodiafiltration or haemofiltration is more effective than haemodialysis in reducing all-cause mortality risk in patients with ESKD...

INTRODUCTION: The presence of acute kidney injury (AKI) was shown to increase the risk of mortality following acute myocardial infarction (AMI), however, data regarding the prognostic impact of AKI in patients with concomitant cardiogenic shock (CS) is limited. The study investigates predictors and the prognostic impact of AKI in patients with CS. METHODS: Consecutive patients with CS from 2019 to 2021 were included at one institution. Laboratory values were retrieved from day of disease onset (day 1) and days 2, 3, 4 and 8 thereafter...

Excessive albumin losses during HC (haemocatharsis) are considered a potential cause of hypoalbuminemia-a key risk factor for mortality. This review on total albumin losses considers albumin "leaking" into the dialysate and losses due to protein/membrane interactions (i.e. adsorption, "secondary membrane formation" and denaturation). The former are fairly easy to determine, usually varying at the level of ~ 2 g to ~ 7 g albumin loss per session. Such values, commonly accepted as representative of the total albumin losses, are often quoted as limits/standards of permissible albumin loss per session...

BACKGROUND: Haemodialysis (HD) requires safe and effective anticoagulation to prevent clot formation within the extracorporeal circuit during dialysis treatments to enable adequate dialysis and minimise adverse events, including major bleeding. Low molecular weight heparin (LMWH) may provide a more predictable dose, reliable anticoagulant effects and be simpler to administer than unfractionated heparin (UFH) for HD anticoagulation, but may accumulate in the kidneys and lead to bleeding...

A 19-year-old woman with known maple syrup urine disease presented to hospital with metabolic crisis in the setting of influenza type A infection and intractable vomiting, rapidly progressing to acute cerebral oedema manifesting as refractory seizures and decreased level of consciousness needing emergency intubation and mechanical ventilation, continuous veno-venous haemodiafiltration and thiopentone coma. A computed tomography scan and magnetic resonance imaging of the brain demonstrated classic signs of cerebral oedema secondary to a metabolic crisis from the metabolic disorder...

BACKGROUND: Volume assessment, dry weight titration, and blood pressure control in pregnant kidney failure patients are often challenging, with physiological fluid accumulation in the trunk and lower limbs and an increased risk of preeclampsia. We used segmental bioimpedance in the volume management of our kidney failure patient on haemodialysis. CASE PRESENTATION: We report a case of a female patient on maintenance haemodiafiltration with no residual kidney function for whom we used segmental bioimpedance to guide dry weight adjustment...

BACKGROUND: Compliance with dialysis fluid ultrapurity standards is a paramount for online modalities. More than 200 dialysis fluid samples have been analyzed monthly for years in our two dialysis units, with compliant microbiological results until mid-2020. AIM: In mid-2020, an unusual occurrence (30%) of contaminated dialysis fluids in dialysis units led us to investigate to determine the source. METHODS: Microbiological methods for aquaphilic bacteria culturing and endotoxin detection in dialysis fluids were routinely performed on a monthly basis for all dialysis machines...

The objective of this case report is to describe the use of extracorporeal therapy, specifically hemodialfiltration, for the treatment of caffeine intoxication. A 12 year old Border Terrier consumed up to 1440 mg/kg of caffeine and rapidly developed clinical signs of tachycardia and tremors. Hemodiafiltration was instituted, using an M60 PrismaFlex cartridge using blood to prime the system due to patient size. Treatment with 11.25 L of therapy fluid (83% dialysate, 17% replacement fluid), or 1.8 L/kg, was provided over 6 h...

OBJECTIVES: To assess the pharmacokinetics/pharmacodynamics (PK/PD) of cefiderocol administered by continuous infusion (CI) in a case series of critically ill patients with carbapenem-resistant Acinetobacter baumannii (CRAB) infections undergoing continuous venovenous haemodiafiltration (CVVHDF). METHODS: Critically ill patients receiving cefiderocol by CI during CVVHDF for documented bloodstream infections (BSIs), ventilator-associated pneumonia (VAP), and/or complicated intrabdominal infections (cIAIs) caused by CRAB and undergoing therapeutic drug monitoring (TDM) from February 2022 to January 2023 were retrospectively assessed...

BACKGROUND: The introduction of high flux (HF) hemodialyzers and their application in single dialyzer hemodiafiltration (sdHDF) for patients on extracorporeal dialysis (ECD) therapy has improved the extraction of uremic toxins, including the low molecular weight protein (LMWP) beta 2 microglobulin (β2M, 11.6 kDa). Similar increases in the extraction of protein-bound uremic toxins (PBUT) and larger LMWP (15-50 kDa) remain elusive. High concomitant losses of albumin prohibit the use of medium cutoff (MCO) or protein-losing hemodialyzers for sdHDF to increase the extraction of these molecules by convective transfer...

BACKGROUND: From 2006 to 2020, 24% of children starting haemodialysis in France weighed < 20 kg. Most new-generation long-term haemodialysis machines do not propose paediatric lines anymore but Fresenius has validated two devices for use in children above 10 kg. Our aim was to compare the daily use of these two devices in children < 20 kg. METHODS: Retrospective single-center evaluation of daily practice with Fresenius 6008® machines, and low-volume paediatric sets (83 mL), as compared to 5008® machines with paediatric lines (108 mL)...

INTRODUCTION: Treatment with continuous renal replacement therapy (CRRT) is common during extracorporeal membrane oxygenation (ECMO). Such ECMO-CRRT has specific technical characteristics, which may affect circuit life. Accordingly, we studied CRRT haemodynamics and circuit life during ECMO. METHODS: ECMO and non-ECMO-CRRT treatments in two adult intensive care units were compared using data collected over a 3-year period. A potential predictor of circuit survival identified in a 60% training data subset as a time-varying covariate within a Cox proportional hazard model was subsequently assessed in the complementary remaining data (40%)...

INTRODUCTION: The antibody response to SARS-CoV-2 vaccine in haemodialysis (HD) patients is diminished compared to healthy subjects. The aim of this study was to compare the presence of reactive SARS-CoV-2 antibodies in patients with high-flux HD and on-line haemodiafiltration (HDF) three and 6 months after the second dose of SARS-CoV-2 vaccine since previous studies indicate that a sustained antibody response correlates with protection from disease. METHODS: We included 216 HD patients of which 157 had on-line HDF and 59 high-flux HD and 46 health care workers as controls and studied the presence of reactive anti-spike IgG antibodies three and 6 months after the second dose of SARS-CoV-2 vaccine...

PURPOSE: To explore pharmacokinetic/pharmacodynamic (PK/PD) profile of continuous infusion (CI) ceftazidime-avibactam for treating difficult-to-treat resistant Gram-negative (DTR-GN) infections in critical patients undergoing continuous venovenous haemodiafiltration (CVVHDF). MATERIALS AND METHODS: Patients treated with CI ceftazidime-avibactam for DTR-GN infections during CVVHDF were retrospectively assessed. Ceftazidime and avibactam concentrations were measured at steady-state and the free fraction (fCss ) was calculated...

AIM: Standard haemodialysis (sHD) is associated with a poor survival and marked adverse intradialytic patient-reported outcome measures (ID-PROMs). Whereas physical ID-PROMs (PID-PROMs) are alleviated by cool dialysate (cHD), survival is prolonged by haemodiafiltration (HDF). So far, PID-PROMs are not prospectively compared between HD and HDF. METHODS: To assess whether PID-PROMs and thermal perception differ between sHD, cHD, low volume HDF (lvHDF) and high volume HDF (hvHDF), 40 patients were cross-over randomized to each modality for 2 weeks...

BACKGROUND: This study investigated the efficacy of the integrated blood purification mode of early haemoperfusion (HP) combined with continuous venovenous haemodiafiltration (CVVHDF) in children with severe viral encephalitis, and evaluated the correlation of cerebrospinal fluid (CSF) neopterin (NPT) levels with prognosis. METHODS: The records of children with viral encephalitis who received blood purification treatment in the authors' hospital from September 2019 to February 2022 were retrospectively analysed...
