High recovery rate of consciousness by high-volume filtrate hemodiafiltration for fulminant hepatitis.

An artificial liver support (ALS) system sustaining patients with acute liver failure (ALF) in good condition until recovery of the native liver or performance of liver transplantation (LT), is essential for the improvement of the poor prognosis of ALF despite the lack of survival benefit. We aimed to investigate the efficacy of various ALS systems for fulminant hepatitis (FH) carried out in our liver unit so far, focusing on the restoration of consciousness from hepatic encephalopathy. One hundred and ten consecutive adult Japanese patients with FH admitted to Chiba University Hospital (Chiba, Japan) between 1988 and 2016 who received ALS were analyzed. Recovery rate of consciousness improved with the increased dialysate flow rate and filtrate rate: 37.5% by plasma exchange (PE), 51.9% by PE + continuous hemodiafiltration (CHDF), 57.7% by slow PE (sPE) + high-flow CHDF (HFCHDF) (Q More effective ALS should be recognized considering the extremely high recovery rate of consciousness. In particular, OLHDF with predilution reduces the cost of substitution fluid by supplying an unlimited amount of dialysate as substitution fluid prepared using an on-line system, and simplifies the procedure for the management.
