Peritoneal Solute tranSPort in Peritoneal DialySiS PatientS: longituDinal ChangeS anD influenCe on Survival
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...
متن کاملPeritoneal glucose exposure and changes in membrane solute transport with time on peritoneal dialysis.
Peritoneal solute transport increases with time on treatment in a proportion of peritoneal dialysis (PD) patients, contributing to ultrafiltration failure. Continuous exposure of the peritoneum to hypertonic glucose solutions results in morphologic damage that may have a causative role in changes in peritoneal function. The purpose of this analysis was to establish whether increased exposure to...
متن کاملLongitudinal study of small solute transport and peritoneal protein clearance in peritoneal dialysis patients.
BACKGROUND AND OBJECTIVES Peritoneal protein clearance (Pcl) is determined by both effective (small pores) membrane area and relative capillary leakiness (large pores). It is not known how these two components change with duration of peritoneal dialysis (PD) in the context of progressive membrane injury and differential attrition of patients with higher Pcl, which has been associated with incre...
متن کاملPhysiological Interpretation of Solute Transport Parameters for Peritoneal Dialysis
A mathematical model for solute distribution within the tissue due to combined processes of diffusion and convective transport through the tissue, through the capillary wall, and by lymphatic absorption, during the exchange of the solute between an organ and external medium is applied for the description of the transport of small, middle and macro molecules. The analytical solutions of the tran...
متن کاملPeritoneal fluid and solute transport: influence of treatment time, peritoneal dialysis modality, and peritonitis incidence.
The integrity of the peritoneal membrane in peritoneal dialysis (PD) is of major importance for adequate dialysis and fluid balance. However, alterations in peritoneal fluid transport, such as ultrafiltration failure, often develop during long-term PD. To investigate peritoneal solute and fluid transport and to analyze the influence of treatment time, peritonitis incidence, and PD modality (con...
