Osmotic water transport across the peritoneal membrane is applied during peritoneal dialysis to remove the excess water accumulated in patients with end-stage renal disease. The discovery of aquaporin water channels and the generation of transgenic animals have stressed the need for novel and accurate methods to unravel molecular mechanisms of water permeability in vivo. Here, we describe the u...

The aim of the present study was to assess the influence of peritoneal permeability expressed as the dialysate-to-plasma ratio of creatinine (D/P Cr) on total and cardiovascular (CV) mortality in a population of peritoneal dialysis (PD) patients during a 6-year observation period. The study recruited 55 patients (mean age: 53 years) treated with PD for a median of 24 months. Hematology paramete...

In previous work from this laboratory (1) studies on equilibrium dialysis were carried out to determine the binding constants for the interaction of human serum albumin with thyroxine and its analogs. The classical technique of equilibrium dialysis as described by Scatchard and others (2-6) was employed. At present it seems clear that thyroxine in human serum migrates to at least three differen...

Background: Peritoneal dialysis (PD) patients have a higher mortality rate than the general population. This study aimed to evaluate the longitudinal changes of peritoneal solute transport and its influence on the prediction of survival in PD patients. Methods: This is a single center retrospective study on patients commencing PD between January 1992 and September 2004, and staying in treatment...

BACKGROUND Using flame photometry technique in the 1970s, the normal value of anion gap (AG) was determined to be 12 ± 4 meq/L. However, with introduction of the autoanalyzers using an ion-selective electrode (ISE), the anion gap value has fallen to lower levels. METHODS A retrospective study of US veterans from a single medical center was performed to determine the value of the anion gap in ...

Among the 1846 patients in the HEMO Study, chronic high-flux dialysis did not significantly affect the primary outcome of the all-cause mortality (ACM) rate or the main secondary composite outcomes, including the rates of first cardiac hospitalization or ACM, first infectious hospitalization or ACM, first 15% decrease in serum albumin levels or ACM, or all non-vascular access-related hospitaliz...

BACKGROUND/AIMS Studies on the risk factors and outcomes of peritonitis within the first 6 months in peritoneal dialysis patients are sparse. This study aims to investigate the risk factors associated with early-onset peritonitis (EOP) and its influence on patients' technique survival and mortality. METHODS This is a retrospective observational cohort study. A total of 483 patients who had at...
