An exploratory study of a novel peritoneal combination dialysate (1.36% glucose/7.5% icodextrin), demonstrating improved ultrafiltration compared to either component studied alone.
OBJECTIVE: Concerns regarding the impact of ultrafiltration failure on peritoneal dialysis and the effect of hypertonic glucose on the peritoneal membrane have lead to a search for alternative dialysates. Computer simulations based on the three-pore theory suggest that a combination of 1.36% glucose and 7.5% icodextrin (glucose polymer) offers an improved ultrafiltration profile. The aim of the present study was to investigate the ultrafiltration profile of this combination fluid. DESIGN: Prospective open study comparing 1.36% glucose, 3.86% glucose, 7.5% icodextrin, and the combination fluid (1.36% glucose/7.5% icodextrin). SETTING: Sheffield Kidney Institute, Northern General Hospital, Sheffield, UK. PATIENTS: 11 patients currently using peritoneal dialysis not previously exposed to icodextrin. MAIN OUTCOME MEASURE: Intraperitoneal volume was measured using a radioisotope dilution method. RESULTS: The combination fluid showed a biphasic ultrafiltration profile, with a steep initial increase in intraperitoneal volume, then a maintained plateau phase for the duration of the study dwell (7 hours). The final volume was greater than that with the 1.36% glucose dwell and the 7.5% icodextrin dwell. The fluid was well tolerated by the patients. CONCLUSIONS: These findings are in keeping with computer simulations using the three-pore model. The combination fluid offers an improved ultrafiltration profile, with a final volume similar to 3.86% glucose, while avoiding exposing the peritoneal membrane to high glucose concentrations. It may have a role as a long dwell to optimize ultrafiltration and possibly prolong peritoneal dialysis technique survival.

Enhanced ultrafiltration using 7.5% icodextrin/1.36% glucose combination dialysate: a pilot study.
OBJECTIVE: A pilot study to compare the use of a combination dialysate (7.5% icodextrin/1.36% glucose) versus icodextrin 7.5% alone for the long dwell in patients on peritoneal dialysis (PD). DESIGN: A 4-week, prospective, randomized crossover study. SETTING: A large regional renal unit providing treatment for a population of 1.7 million. PATIENTS: Five patients on continuous ambulatory PD (CAPD) and 3 patients on automated PD. MAIN OUTCOME MEASUREMENTS: Long-dwell and 24-hour ultrafiltration volumes, body weight, 24-hour ambulatory blood pressure, and antihypertensive/diuretic tablet count. RESULTS: The use of the combination dialysate resulted in an increase in the median (interquartile range) long-dwell ultrafiltration, from 750 (650-828) mL to 1000 (889-1100) mL (p < 0.001), and 24-hour ultrafiltration, from 739 (400-1623) mL to 956 (700-1750) mL (p < 0.001). Weight, blood pressure, and tablet count remained unchanged. CONCLUSIONS: The use of the novel combination dialysate resulted in a 33% increase in long-dwell ultrafiltration and a 29% increase in 24-hour ultrafiltration.
