[Technological advances and micro-inflammation in dialysis patients]
Abstract:
As currently performed, on line hemodiafiltration reduces, but does not normalize, the micro-inflammation of uremic patients. Recent technological advances make it possible to further reduce the inflammation connected to the dialysis treatment. Short bacterial DNA fragments are pro-inflammatory and can be detected in the dialysis fluids. However, their determination is not currently within normal controls of the quality of the dialysate. The scenario may change once the analysis of these fragments yields reliable, inexpensive, quick and easy to evaluate the results. At variance with standard bicarbonate dialysate, Citrate dialysate induces far less inflammation both for the well-known anti-inflammatory effect of such buffer and also because it is completely acetate free, e.g. a definitely pro-inflammatory buffer. However, the extensive use of citrate dialysate in chronic dialysis is prevented because of concerns about its potential calcium lowering effect. In our view, high convective exchange on line hemodiafiltration performed with dialysate, whose sterility and a-pirogenicity is guaranteed by increasingly sophisticated controls and with citrate buffer whose safety is certified, can serve as the gold standard of dialysis treatments in future.
Insights
On-line hemodiafiltration can reduce inflammation in uremic patients. Advanced techniques using citrate dialysate, alongside stringent quality controls, may offer a future gold standard for dialysis treatments.
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.

Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
