Exploring the Modulatory Effect of the Dialyzer Membrane Choice on Hemodialysisassociated Thromboinflammation: a Prospective Randomized Cross-over Trial

This clinical trial investigates whether the dialyzer membrane influences hemodialysis-associated thromboinflammation. Specifically, it evaluates the effects of 3 commercially available dialyzer membrane types on immune cell activation and thromboinflammatory responses. During this trial, participants will undergo standard hemodialysis (3 sessions/week, 4 hours each) and receive three different dialyzer membranes in a crossover design, one for each session with a total study duration of 1 week. During each session blood samples will be collected (at baseline, hourly, and at the end of dialysis) and additionally, after each session, the used dialysis circuit will be rinsed to recover adherent cells. The study aims to: * Assess whether the dialyzer membrane influences leukocyte and platelet activation . * Evaluate whether the dialyzer membrane influences neutrophil extracellular trap (NET) formation. * Evaluate whether the dialyzer membrane influences the transcriptomic profiles of immune cells.
