Continuous Erythropoietin Receptor Activator (C.E.R.A.) is a new agent that in development for the treatment of anemia with extended administration intervals patients who have chronic kidney disease (CKD), both those on and not dialysis. This was an open-label, randomized, multicenter, two-period, crossover study erythropoiesis-stimulating agentnaïve had CKD were receiving peritoneal After 1-wk run-in period, 16 randomly assigned to receive single intravenous C.E.R.A. 0.4 microg/kg (n = 8)...

The mechanisms of clearance circulating plasma DNA are not fully understood, and so we aimed to examine it in patients with impaired renal function compared healthy individuals. We also assessed the effect peritoneal dialysis hemodialysis on cell‐free (cfDNA) our treated patients. Overall, 20 volunteers, chronic kidney disease (CKD), 18 undergoing (PD), 17 (HD; high‐flux polysulfone membrane) were examined. Cell‐free levels determined using real‐time GADPH gene sequence amplification. cfDNA...

Abstract Asymmetric dimethylarginine (ADMA) is a mediator of endothelial dysfunction. Production and elimination ADMA may be affected by the type renal replacement therapy used oxidative stress. Plasma ADMA, advanced glycation end products (AGE), homocysteine were assessed in 59 subjects: 20 hemodialysis (HD) patients, 19 patients undergoing peritoneal dialysis (PD), controls. Results compared between groups. The effect 8 weeks HD high‐volume predilution hemodiafiltration (HDF) was...

Objective In this study, we compared the activity of interleukin-6 (IL-6), a marker ongoing peritoneal inflammation and biocompatibility, its other signaling components, soluble IL-6 receptor (sIL-6R) Gp130 (sGp130), in effluent from patients treated with icodextrin-based (E) dialysis (PD) solution glucose-based bicarbonate/lactate–buffered (P) solution. Methods Using baseline ultrafiltration capacity, 33 stable incident PD were allocated either to P only ( n = 20) or plus E for overnight...

Purpose. Cell-free plasma DNA (cfDNA) levels originating predominantly from apoptotic leukocytes were found to rise during hemodialysis (HD) session, and as such are considered a marker of HD membrane biocompatibility. The purpose our study was determine the changes cfDNA two consecutive high-flux polysulphone sessions after long (HD-L) short (HD-S) interdialytic interval. Methods. A total 17 patients examined. Prior at 30 240 min, (using real-time PCR) leukocyte count determined. Results....

Abstract: Renal anemia significantly affects the morbidity and mortality of dialysis patients. The aim present study was to establish whether severity success its treatment differs when using high‐flux (HF) or low‐flux (LF) hemodialysis. Twenty‐five patients on long‐term hemodialysis with a mean hematocrit (Hct) 33%, S alb 36 g/L, Kt/V urea 1.5 were divided into Groups X (n = 13) Y 12) in prospective randomized crossover study. Group initially treated LF be followed by HF for 8 weeks each...

&lt;i&gt;Background/Aims:&lt;/i&gt; Patients with chronic renal failure (CRF) secondary to diabetes mellitus show a high incidence of atherosclerosis its thrombotic complications. Both CRF and type 2 (DM2) results in fibrinolysis defects causally related atherogenesis thrombogenesis. It is not well known whether or and, if so, how altered patients both DM2. Our study was designed (1) identify the defect present DM2-mediated treated by long-term hemodialysis (DM2HD), (2) establish metabolic...

Background. Evaluation of acid-base disorders using the Stewart-Fencl principle is based on assessment independent factors: strong ion difference (SID) and total concentration non-volatile weak acids (Atot). This approach allows for a more detailed evaluation cause imbalance than conventional bicarbonate-centered Henderson-Hasselbalch principle, which necessary yet insufficient condition to describe state system. The aim our study was assess in peritoneal dialysis (PD) patients both these...

Anemia in chronic renal failure causes a number of serious problems to the patient. As result, it is imperative make use all rational options alleviate it. The present study addresses question, answer which not yet known, whether or degree anemia depends on efficacy continuous ambulatory peritoneal dialysis (CAPD) and, if so, what importance clearance and residual function is.

Abstract Icodextrin peritoneal dialysis (PD) solution has been shown to increase interleukin‐6 (IL‐6) levels in PD effluent as well leukocyte and mesothelial cell count. Mesothelial cells release cancer antigen 125 (CA125), which is used a marker of mass. This 1‐year prospective study was designed compare population, its inflammatory phenotype biocompatibility biomarkers IL‐6 CA125 between icodextrin (E) glucose bicarbonate/lactate (P) based solutions.
