Optimised versus standard automated peritoneal dialysis regimens pilot study (OptiStAR): A randomised controlled...

Area of Science:

• Nephrology
• Biomedical Engineering

Background:

• End-stage kidney disease is rising globally, increasing demand for home-based therapies like peritoneal dialysis (PD).
• Glucose absorption by peritoneal tissues is a significant limitation of current PD treatments.

Purpose of the Study:

• To evaluate a novel, theoretically glucose-sparing PD regimen compared to a standard regimen.
• To assess the impact of optimized PD prescriptions on ultrafiltration and solute clearance.

Main Methods:

• A crossover study comparing a standard PD regimen with an optimized regimen featuring 'ultrafiltration' and 'clearance' cycles.
• Twenty-one prevalent PD patients received both regimens; six were excluded from analysis.

Main Results:

• No significant difference in median glucose absorption between standard (43 g) and optimized (44 g) regimens.
• Optimized PD significantly improved ultrafiltration volume and weekly Kt/V for creatinine and urea.
• Ultrafiltration efficiency was significantly higher with optimized regimens, with no difference in sodium removal.

Conclusions:

• Optimized PD regimens are feasible and well-tolerated in a pilot study.
• The optimized approach may enhance ultrafiltration efficiency and small solute clearance without increasing glucose absorption.
• Larger studies are needed to confirm the glucose-sparing potential of optimized PD prescriptions.
