Haemodialysate: long neglected, difficult to optimize, may modify hard outcomes

Area of Science:

• Nephrology
• Clinical Medicine
• Dialysis Therapy

Background:

• Hemodialysate composition is increasingly linked to adverse patient outcomes.
• Limited clinical trial data restricts guideline recommendations for hemodialysis fluid management.
• Expert opinion is vital due to the scarcity of evidence-based practices.

Purpose of the Study:

• To highlight the importance of hemodialysate composition in patient care.
• To discuss the challenges in balancing rapid correction of imbalances with gradual adjustment.
• To explore personalized medicine approaches for optimizing hemodialysate.

Main Methods:

• Review of recent expert opinions and observational studies on hemodialysate composition.
• Analysis of the complexities in hemodialysis fluid design considering patient variability.
• Discussion on the need for novel clinical trial designs.

Main Results:

• Observational studies suggest a link between hemodialysate composition and adverse events.
• Current guidelines offer limited positive recommendations, focusing more on restrictions.
• Individual patient factors significantly complicate optimal hemodialysate formulation.

Conclusions:

• A personalized medicine approach to hemodialysate composition holds promise for improved patient outcomes.
• Further research, including robust clinical trial designs, is essential to validate individualized hemodialysis strategies.
• Balancing acute correction needs with gradual physiological adaptation is key in hemodialysate prescription.
