Myeloperoxidase serves as a marker of oxidative stress during single haemodialysis session using two different biocompatible dialysis membranes.

Background: There is increased oxidative stress in patients undergoing haemodialysis (HD); however, little is known of how different dialysis membranes contribute to the oxidative stress induced by the dialysis procedure per se. We therefore studied the influence of two different dialysis membranes on oxidative stress during HD.

Methods: Eight patients undergoing HD three times per week were enrolled in this cross-controlled study.
