Study Arms (2)

Dialysate magnesium 1.0 mmol/L

EXPERIMENTAL

Increase dialysate magnesium from 0.5 mmol/L to 1.0 mmol/L.

Other: Dialysate magnesium (1.0 mmol/L)

Dialysate magnesium 0.5 mmol/L

ACTIVE COMPARATOR

Maintain dialysate magnesium at 0.5 mmol/L.

Other: Dialysate magnesium (0.5 mmol/L)

Interventions

Dialysate magnesium will be increased from 0.5 mmol/L to 1.0 mmol/L for 4 weeks after which subjects will return to dialysate magnesium 0.5 mmol/L for 2 weeks observation.

Dialysate magnesium 1.0 mmol/L

Dialysate magnesium will be maintained at 0.5 mmol/L for the duration of the trial.

Dialysate magnesium 0.5 mmol/L

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥ 18 years.
  • Treatment with maintenance haemodialysis for more than 3 months.
  • Dialysate magnesium of 0.5 mmol/L (standard concentration).
  • Serum magnesium \< 1.2 mmol/L on average of previous measurements within the last 3 months.
  • Women of childbearing age must be actively using contraceptive therapy (p-pills, estrogen depots or intrauterine device) as well as have a negative pregnancy test.
  • Written informed consent.

You may not qualify if:

  • Treatment with peritoneal dialysis.
  • Parathyroid hormone \> 66 ρmol/L.
  • Previous parathyroidectomy.
  • Current treatment with magnesium containing medication or supplements.
  • Other diseases or conditions, which, in the opinion of the site investigator, would prevent participation in or completion of the trial.
  • Pregnancy or breastfeeding.
