AbstractThe 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. PDF employs a plasma separator that has a sieving coefficient of 0.3 for albumin and which requires flowing dialysate outside the hollow fiber. For substitute liquid, 1,200 ml of fresh frozen plasma followed by 50 ml of 25% albumin solution is used for 8 h as 1 session. In a single-center study, 24 patients with septic shock were admitted to the ICU, then 37.7 +/- 30.0 h later, 7 patients received PDF. The patients' Sequential Organ Failure Assessment (SOFA) scores had increased from 14.9 +/- 3.6 on ICU admission to 17.1 +/- 3.0 before PDF procedure. PDF was performed, with an average of 7.4 +/- 4.4 sessions (range 3-15) per patient. Five patients survived after day 28, thus the 28-day mortality rate was 29%. In our multicenter study, 33 patients with severe sepsis who simultaneously suffered from liver dysfunction were enrolled and received PDF. 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.Copyright 2010 S. Karger AG, Basel.
