Serum disaccharides and osmolality in CCPD patients using icodextrin or glucose as daytime dwell.

Abstract

The serum icodextrin metabolite levels in the present study increased markedly and were the same as those found previously in continuous ambulatory peritoneal dialysis patients treated with icodextrin, despite the longer dwell time for CCPD patients (14-16 hr versus 8-12 hr). The initial decrease in serum sodium concentration was followed by an increase to a concentration not different from baseline at 12 months. The pathophysiology of this finding is speculated. Calculated osmolal gap in icodextrin patients increased significantly (p < 0.01) at every follow-up visit, and could be explained by the serum icodextrin metabolite increase. We encountered no clinical side effects of the observed levels of icodextrin metabolites.
