BACKGROUND End-stage renal disease (ESRD) patients on long-term hemodialysis (HD) may be under increased oxidative stress, caused by either HD or renal failure. Plasma F2-isoprostanes have been established as an important indicator of in vivo oxidative stress. METHODS Plasma esterified F2-isoprostanes were measured in 25 HD patients and 23 controls with(More)
Dialysis is associated with an increased generation of oxidants, which play an important part in the development of endothelial dysfunction and atherogenesis. Markers of oxidative stress include F2-isoprostanes and ethane. Measurements in dialysis patients before dialysis showed higher levels of esterified plasma F2-isoprostanes (1.62 +/- 0.73 ng/mL) than(More)
BACKGROUND Cross-sectional studies have shown an inverse correlation between serum C-reactive protein (CRP) and serum albumin concentration in hemodialysis patients. The net effects of inflammation and dietary protein intake on nutritional markers over time are unknown. METHODS To explore the effects of CRP and normalized protein catabolic rate (nPCR) on(More)
Oxidant stress may play a role in the accelerated pathology of patients on dialysis, especially in the development of cardiovascular disease, which is a frequent condition in end-stage renal disease (ESRD) patients. Measurement of hydrocarbons can be employed to assess oxidant stress since breath hydrocarbons have been directly traced to in vivo breakdown(More)
A new polymer-based sorbent cartridge has been recently developed for enhancing middle molecule removal during hemodialysis. The cartridge (Betasorb, Renaltech, New York, USA) has been designed to be placed in series with the dialyzer in the blood circuit. It is therefore important to evaluate the distribution of flow into the blood compartment of the(More)
End-stage renal disease (ESRD) is more frequent in African Americans (blacks) compared to Caucasian Americans (whites). Identification of remediable causes of the increased prevalence has the potential to reduce the excess burden of ESRD. Because renal fibrosis is a correlate of progressive renal failure and a dominant feature of ESRD, and because(More)
Sensitivity to iron dextran is a potent obstacle to maintaining optimum iron status in patients with dialysis-associated anemia. As part of the North American clinical trials for iron sucrose injection, we examined the effect of intravenous (IV) iron sucrose in 23 hemodialysis patients with documented sensitivity to iron dextran, ongoing epoetin alfa(More)
Adoption of high rate of ultrafiltration (UF) during hemodialysis (HD) may affect the hemorhelogical blood profile, by changing Hematocrit (Hct) and the concentration of plasma proteins, which may in turn interfere with tissue perfusion. The aim of this work is to examine the effect of acute volume change during dialysis on the hemorheological variables.(More)
