Some of the morbidity associated with chronic hemodialysis is thought to result from retention of large molecular weight solutes that are poorly removed by diffusion in conventional hemodialysis. Hemodiafiltration combines convective and diffusive solute removal in a single therapy. The hypothesis that hemodiafiltration provides better solute removal than high-flux hemodialysis was tested in a ...
Conventional hemodialysis, which is based on the diffusive transport of solutes, is the most widely used renal replacement therapy. It effectively removes small solutes such as urea and corrects fluid, electrolyte and acid-base imbalance. However, solute diffusion coefficients decreased rapidly as molecular size increased. Because of this, middle and large molecules are not removed effectively ...
BACKGROUND Renal replacement therapy may have a favorable effect on diastolic left ventricular function, but it is not clear whether hemodiafiltration is superior to hemodialysis in this field. Nitric oxide (NO) and asymmetric dimethylarginine (ADMA) may play a role in the changes of intracardiac hemodynamics, but it is not clear whether the different renal replacement methods have disparate in...
INTRODUCTION Retrospective studies showed that hemodiafiltration was associated with a reduced risk of mortality compared with standard hemodialysis in the patients with end-stage renal disease. Recently, a few prospective randomized clinical trials found no advantage in survival with hemodiafiltration as compared with high-flux hemodialysis and low-flux hemodialysis. The aim of this study was ...
BACKGROUND AND AIMS Arterial stiffness seems to be influenced by the dialysis method, but studies are sparse and the results discordant. High substitution volume online hemodiafiltration appears to have beneficial cardiovascular effects in dialysis patients, but its effects on arterial stiffness are not investigated. We aimed to analyze arterial stiffness parameters in high substitution volume ...
INTRODUCTION Patients on dialysis have a high rate of death, mainly of cardiovascular cause. Nephrologists are actively looking for ways to improve patients' outcomes, and alternative dialysis strategies, such as long conventional hemodialysis and hemodiafiltration, are currently being investigated. The aim of this study was to compare anemia, nutrition, inflammation, mineral metabolism, and 3...
In patients with ESRD, the effects of online hemodiafiltration on all-cause mortality and cardiovascular events are unclear. In this prospective study, we randomly assigned 714 chronic hemodialysis patients to online postdilution hemodiafiltration (n=358) or to continue low-flux hemodialysis (n=356). The primary outcome measure was all-cause mortality. The main secondary endpoint was a composit...
Hemodiafiltration, a process in which whole blood is first diluted with a physiologic electrolyte solution and then ultrafiltered across a membrane to convectively remove solutes and excess water, has been applied clinically for the first time. Six-hour hemodiafiltration with a 1.6 m.2 hollow-fiber ultrafilter was applied intermittently to an anephric patient as an alternative to 6-hour hemodia...
Multiple myeloma (MM) is a malignancy with excessive production of monoclonal proteins. At disease presentation 30% of MM patients have significant renal impairment which may progress to renal failure requiring dialysis. Besides chemotherapy extracorporeal elimination procedures such as plasma exchange have been applied as adjuvant strategies to eliminate free light chains from circulating bloo...
Aim: The prolongation of T-wave-peak-to-end interval (Tpe) and arrhythmogenic index (AIX) could predict arrhythmias. Developing of ventricular arrhythmias is increased during hemodialysis (HD), but the effects of hemodiafiltration (HDF) on ventricular repolarization have not been elucidated yet. Methods: Thirty patients was investigated while they were receiving hemodiafiltration over a period ...
