Changing magnesium and acid type in dialysis fluid to reduce clotting and immune activation
Official title: Effect of Modifying Magnesium Concentration in Citrate-enriched Dialysate on Hemodialysis-associated Thromboinflammation: a Local Pilot OMAGOD Plus Trial
Run by Universitair Ziekenhuis Brussel · NCT07206524 · Data updated 2026-11-12
This project tests whether changing the magnesium level and acid type in dialysis fluid can reduce immune-driven clotting and inflammation in people on maintenance hemodialysis.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults enrolled in the OMAGOD pilot who receive maintenance hemodialysis and can attend the Universitair Ziekenhuis Brussel for the extra sampling sessions.
✕Probably not a fit
Patients who are not enrolled in the OMAGOD pilot, those on non-hemodialysis modalities, or those unable to attend the additional sampling visits are not eligible and unlikely to benefit from this nested study.

What this trial studies
This nested monocentric sub-study enrolls participants from the multicenter OMAGOD pilot and uses a crossover design with three dialysate compositions given in two-week periods. Each participant receives standard hemodialysis while switching between citrate-acid and acetic-acid dialysates with different magnesium concentrations. During selected midweek sessions, serial blood samples are taken at baseline, hourly, and at the end of dialysis, and the used dialysis circuit is rinsed to collect adherent cells. Outcomes focus on immune cell activation, neutrophil extracellular trap formation, and other thromboinflammatory markers.
Why it matters
Potential benefit: If successful, this approach could reduce dialysis-associated clotting and inflammation and improve treatment comfort and safety.
How similar studies have gone: Previous studies have reported reductions in clotting and inflammation with citrate-based dialysate and altered magnesium, but applying these specific magnesium concentrations with NET-focused measurements is relatively novel.
