The Uremic Retention Solute p-Cresyl Sulfate and Markers of Endothelial Damage

p-Cresyl sulfate induces shedding of endothelial microparticles in the absence of overt endothelial damage in vitro and is independently associated with the number of endothelial microparticles in hemodialysis patients. These findings suggest that p-cresyl sulfate alters endothelial function in hemodialysis patients.
