Direct infusion of ascites into the blood circuit during hemodiafiltration in uremic patients with cirrhosis.

Two chronic dialysis patients with massive ascites caused by cirrhosis were treated by infusion of their ascites directly into the blood circuit. This stabilized their hemodynamics during dialysis, facilitating the control of weight gain and ascites, and thus markedly improving their general condition. Long-term use of this therapy was able to prevent the accumulation of ascitic fluid. Interestingly, fever occurred when this therapy was performed with hemodialysis, but not with hemofiltration or hemodiafiltration, suggesting that a pyrogen in the ascites was removed by filtration.
