Multicenter Study Clinical Trial
Plasma dia-filtration for severe sepsis.
The mortality rate in severe sepsis is 30-50%, and independent liver and renal dysfunction impacts significantly on hospital and intensive care mortality. If 4 or more organs fail, mortality is > 90%. Recently, we reported a novel plasmapheresis--plasma diafiltration (PDF)--the concept of which is plasma filtration with dialysis. ⋯ On average, 12.0 +/- 16.4 sessions (range 2-70) per patient were performed. The 28-day mortality rate was 36.4%, while the predicted death rate was 68.0 +/- 17.7%. These findings suggest that PDF is a simple modality and may become a useful strategy for treatment of patients with septic multiple organ failure.

Acute kidney injury (AKI) is a common complication among critical illnesses. In severe cases, renal replacement therapy (RRT) is required. It has been reported that hospital mortality of the patients who require RRT is more than 60%. ⋯ RRT practice is not aligned with the best evidence and variations in practice may be responsible for significant morbidity. The BEST Kidney Study has generated several hypotheses related to RRT practice in the intensive care unit. Such hypotheses will need to be tested in future clinical trials and hopefully help reduce practice variations for patients with AKI requiring RRT.
