BACKGROUND Increased levels of oxidized proteins have been reported in the serum of patients with end-stage renal disease, though little is known regarding the oxidized protein content of the dialysate in patients on peritoneal dialysis (PD) and no information is available as to how this may correlate with important clinical and laboratory variables, including abnormal peritoneal membrane funct...

BACKGROUND Dialysate [Na+] is often overlooked as a contributor to hypertension in patients on haemodialysis (HD). We report observational experience with a facility level decrease in dialysate [Na+] from 141 mmol/l to 138 mmol/l, in the absence of concurrent change with respect to dietary sodium regulation. METHODS The sample comprised all patients (n=52) dialysing at a single HD facility ov...

BACKGROUND AND OBJECTIVES Previous in vitro and clinical studies showed that the urea mass transfer-area coefficient (K(o)A) increased with increasing dialysate flow rate. This observation led to increased dialysate flow rates in an attempt to maximize the delivered dose of dialysis (Kt/V(urea)). Recently, we showed that urea K(o)A was independent of dialysate flow rate in the range 500 to 800 ...

abstract background: hypertension is very common in patients with end-stage renal disease and accelerates cardiovascular morbidity and mortality. the most important factor in achieving normal blood pressure in these patients is reaching dry weight. sodium and extracellular fl uid balance play a vital role in this regard. considering the lack of consensus about the effi cacy of stepwise sodium p...

We describe a method for quantitatively estimating 24 ninhydrin-reacting substances, including the commoner amino acids, in fecal dialysate prepared from ingested dialysis bags retrieved from fresh stool. It is accurate to 2 mumol of alpha-amino nitrogen per liter of fecal dialysate, and for most substances recovery of added standards is 100%. It involves dilution, ultrafiltration, and automate...

A number of bacterial cytokine-inducing substances (CIS) such as lipopolysaccharides (LPS) and exotoxins have been detected in dialysate and may contribute to inflammation in hemodialysis patients. Short DNA fragments, oligodeoxynucleotides (ODN) of 6 to 20 nucleotides, are able to bind to Toll-like receptors and are stimulatory on immune cells. ODN induce natural killer cell activity and induc...

AIMS To investigate the dynamics between plasma and dialysate glucose during hypoglycaemia in children. STUDY DESIGN Six children in prepuberty or early puberty were investigated by multiple blood sampling and microdialysis of subcutaneous adipose tissue during a standard arginine-insulin tolerance test. Glucose and glycerol, as an index of lipolysis, were measured in samples from both compar...

OBJECTIVES Protein-energy malnutrition as a consequence of deficient protein intake frequently occurs in peritoneal dialysis (PD) patients. Previously, we showed that peritoneal dialysate containing a mixture of amino acids (AA) and glucose has anabolic effects. However AA-dialysate has been reported to increase intraperitoneal protein and AA losses and the release of proinflammatory cytokines ...

Human peritoneal mesothelial cells (HPMCs) are a critical component of the peritoneal membrane and play a pivotal role in dialysis adequacy. Loss of HPMCs can contribute to complications in peritoneal dialysis. Compelling evidence has shown that high-dialysate glucose is a key factor causing functional changes and cell death in HPMCs. We investigated the mechanism of HPMC apoptosis induced by h...

OBJECTIVE The dialysate concentration of large proteins increases, on average, linearly during the whole peritoneal dialysis dwell, and this linear pattern seems to be independent of the rate of ultrafiltration induced by dialysis fluid. However, we observed a high variability of protein kinetics in individual dwell studies. Therefore, we studied the details of the kinetic pattern of peritoneal...
