[Technological advances and micro-inflammation in dialysis patients]

Area of Science:

• Nephrology
• Biomedical Engineering
• Inflammation Research

Background:

• Uremic micro-inflammation persists despite current on-line hemodiafiltration.
• Bacterial DNA fragments in dialysis fluids contribute to inflammation but are not routinely monitored.
• Acetate-based dialysate is pro-inflammatory, unlike citrate.

Purpose of the Study:

• To explore advanced methods for reducing dialysis-related inflammation.
• To evaluate the potential of citrate dialysate in on-line hemodiafiltration.
• To propose a future gold standard for dialysis treatment.

Main Methods:

• Utilizing on-line hemodiafiltration with high convective exchange.
• Employing citrate dialysate to leverage its anti-inflammatory properties.
• Ensuring dialysate sterility and a-pyrogenicity through advanced quality controls.

Main Results:

• Citrate dialysate demonstrates reduced inflammation compared to standard bicarbonate dialysate.
• Concerns regarding citrate's calcium-lowering effect limit its widespread use.
• Technological advancements enable enhanced control over dialysate quality.

Conclusions:

• High-volume on-line hemodiafiltration with certified citrate dialysate and robust quality control shows promise.
• This approach could establish a new gold standard for dialysis, minimizing inflammation.
• Further research is needed to address citrate dialysate's safety concerns in chronic dialysis.
