Removing excess sodium in hemodialysis patients using peritoneal dialysis

Initial Feasibility Pilot Study of Interdialytic Peritoneal Ultrafiltration to Manage Volume Status in Hemodialysis Patients

Phase 2 Interventional London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's · NCT04603014

This study is testing if a new method using peritoneal dialysis can help people on hemodialysis get rid of extra sodium and improve their health between treatments.

What this trial studies

This pilot study investigates the feasibility and effectiveness of interdialytic peritoneal ultrafiltration (iPUF) in chronic hemodialysis patients. Participants will undergo the surgical insertion of a Tenckhoff peritoneal dialysis catheter and receive a 10% dextrose solution for sodium removal between hemodialysis sessions. The study will monitor sodium levels using magnetic resonance imaging and assess patient safety through symptom tracking and blood pressure monitoring. The intervention aims to improve volume management and sodium removal in patients struggling with excess sodium retention.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with significant interdialytic weight gain or difficulty achieving dry weight on their current hemodialysis regimen.

Not a fit: Patients with contraindications to peritoneal dialysis or those with uncontrolled diabetes or active infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance sodium removal and improve overall health outcomes for patients on hemodialysis.

How similar studies have performed: While this approach is novel, similar studies exploring sodium removal techniques in dialysis patients have shown promising results.
