    Abstract:
    BACKGROUND AND METHODS: Icodextrin 7.5% is an iso-osmolar, glucose polymer-containing peritoneal dialysis solution with an ultrafiltration potential similar to glucose 3.86%. We compared in an open, randomized, prospective study the ultrafiltration potential of icodextrin with that of glucose during the daytime dwell of 23 patients treated with automated peritoneal dialysis (CCPD). RESULTS: Daytime ultrafiltration volume and 24-h ultrafiltration volume increased significantly in icodextrin-treated patients (n = 11) at 3 and 6 months, allowing patients a less rigid fluid restriction or an adapted treatment schedule. This improved the patients' subjective well-being. Although ultrafiltration at 9 and 12 months also increased it did not reach statistical significance. Similar to the gain in ultrafiltration volume, 24-h dialysate creatinine clearance per 1.73 m2 (DCl/1.73 m2) and DCl/1.73 m2 per litre used dialysate (DCl/1.73 m2/l) increased in icodextrin-treated patients. DCl/1.73 m2/l per litre ultrafiltrate (DCl/1.73 m2/l/UF) did not increase. No side-effects of icodextrin were encountered, although serum disaccharide levels increased. CONCLUSION: Icodextrin enhances ultrafiltration during the daytime dwell in CCPD patients. As a result of an increased 24-h ultrafiltration volume, DCl/1.73 m2 and DCl/1.73 m2/l improve. DCl/1.73 m2/l/UF does not rise, which suggests that the increase in DCl/1.73 m2 and DCl/1.73 m2/l is caused by convective transport.
