Lower blood concentrations of protein-bound solutes have been directly linked to better outcomes in patients on dialysis. Studies indicate that clearance of protein-bound solutes is more efficient in patients on hemodialysis than in those on peritoneal dialysis; however, paradoxically, the circulating levels of these solutes are lower in patients on peritoneal dialysis. Vanholder and colleagues consider possible explanations for this discrepancy, such as differences in intestinal generation or metabolism of these molecules.
