Is this trial a fit for you?

Likely a good fit

Adults 18 years or older on maintenance hemodialysis for at least 3 months, treated three times weekly, able to consent.

Probably not a fit

Patients with acute kidney injury or severe COPD or those unable to consent may not experience any potential benefit from this study.

What this trial studies

This single-centre cross-sectional observational study collects demographic data, medical and dialysis history, plus a 2-day food diary to estimate dietary renal acid load. Bicarbonate levels are measured before and after a dialysis session to explore how current dialysis practices influence metabolic acidosis in patients with CKD on thrice-weekly treatment. The goal is to understand whether individualizing dialysate bicarbonate concentration could improve bicarbonate control for patients at this center. The study does not involve an intervention and will describe associations between patient factors, treatment details, and bicarbonate outcomes.

Why it matters

Potential benefit: If successful, findings could inform more personalized dialysis practices to better control bicarbonate levels and metabolic acidosis in dialysis patients.

How similar studies have gone: Previous observational work in dialysis populations has described factors linked to bicarbonate balance, supporting the value of this approach, though this specific focus on individualizing dialysate exposure is relatively exploratory.
