Hemoglobin and plasma vitamin C levels in patients on peritoneal dialysis.

Objective: To determine the contribution of vitamin C (Vit C) status in relation to hemoglobin (Hb) levels in patients on long-term peritoneal dialysis (PD).

Methods: 56 stable PD patients were evaluated in a cross-sectional survey. Plasma samples were collected for Vit C (analyzed by HPLC with electrochemical detection) and high-sensitivity C-reactive protein (hs-CRP) determinations.

The utility of two daytime icodextrin exchanges to reduce dextrose exposure in automated peritoneal dialysis patients: a pilot study of nine patients.

Background: The use of dextrose-containing solutions in peritoneal dialysis (PD) is thought to be associated with glucose-related toxicity both to the peritoneal membrane and systemically. There has, therefore, been considerable interest in minimizing the use of dextrose exposure during PD. The present study was designed to explore the use of icodextrin in patients with high/high-average transporter characteristics for two exchanges per day to minimize glucose exposure.

Measurement of intraperitoneal volume by segmental bioimpedance analysis during peritoneal dialysis.

Background: Currently, ultrafiltration during peritoneal dialysis is determined from direct measurement of weight differences between the initial filling and final draining volumes. A new technique based on segmental bioimpedance analysis (SBIA) has been developed to accurately measure intraperitoneal volume continuously during peritoneal dialysis.

Methods: Twenty-two peritoneal dialysis patients were studied in a supine position during peritoneal dialysis consisting of 4 tidal exchanges (TPD).
