The Relationship between Ultrafiltrate Volume with Icodextrin and Peritoneal Transport Pattern according to the Peritoneal Equilibration Test

Abstract

Mean drained volume was similar between the two solution groups. High transporters, as defined by D4/D0, achieved higher ultrafiltration with 7.5% Ico than with 3.86% Glu solution. This is most likely due to the higher number of small pores in the peritoneal membrane. Low transporters, as classified by D/Pcr, achieved lower ultrafiltration with 7.5% Ico than with 3.86% Glu solution. The deltaV (I-G) and the PET results showed significant correlation, confirming that high transporters have a higher ultrafiltration volume with 7.5% Ico. The total B2M mass obtained with 7.5% Ico was greater than with 3.86% Glu solution and significantly higher in the high transport patients, indicating a larger number of small pores. Thus, the deltaV (I-G) could give us an idea of the peritoneal transport pattern in peritoneal dialysis patients.
