Hemodiafiltration (HDF) is a renal replacement therapy that utilizes both diffusive clearance and convective transport to achieve greater clearance of middle-molecular-weight solutes. Among other factors, important prerequisites for the implementation of HDF include access to high-flux dialyzers, achievement of high blood flow rates, and availability of high volumes of sterile substitution/replacement fluids. Online hemodiafiltration (OL-HDF) is an established kidney replacement therapy, frequently used in many countries.

Maintaining phosphorus balance in in-center hemodialysis (ICHD) patients is problematic despite recommended dietary restriction, dialysis, and phosphate binder use. Rarely is P content in prescribed medications considered, but this source should raise concern. Data was obtained from the Fresenius Kidney Care (FKC) electronic data warehouse Knowledge Center and MedReview-eRx accessed Surescripts, housing > 80% of US-filled prescriptions.

Background/aim: Home hemodialysis (HHD) has been associated with improved clinical outcomes vs. in-center HD (ICHD). The prevalence of HHD in the United States is still very low at 1.

Background: Inadequate removal of extracellular volume markedly increases blood pressure and contributes to high morbidity and mortality in hemodialysis patients. Advances in fluid management are needed to improve clinical outcomes. The aim of this quality improvement project was to examine the advantages of using a hematocrit-based, blood volume monitor (Crit-Line * ) for 12 months, as part of a clinic-wide, fluid management program in one dialysis facility.

Although dialytic removal of phosphate significantly contributes to the management of phosphate levels in end-stage renal disease, many patients on peritoneal dialysis (PD) still do not reach optimal phosphate control. The present review discusses the impact of PD modality--continuous ambulatory (CAPD) or automated (APD)--on phosphate removal. Relevant factors are the diffusive properties of the phosphate anion and the kinetics of phosphate distribution in various body compartments.

Background: Conventional peritoneal dialysis fluids (PDFs) consist of ready-to-use solutions with an acidic pH. Sterilization of these fluids is known to generate high levels of glucose degradation products (GDPs). Although several neutral-pH, low-GDP PD solutions have been developed, none are commercially available in the United States.

Glucose degradation products (GDPs) are highly reactive precursors of advanced glycation end-products (AGEs). High glucose concentrations, GDPs, and AGEs can activate specific pathways, including inflammatory and oxidative stress response pathways, which may adversely affect the cardiovascular system. This review discusses the impact and possible mechanisms of action of GDPs and AGEs with regard to cardiovascular toxicity in chronic kidney disease patients.
