Abstract

Research in the treatment of fulminant hepatic failure is hampered by the lack of a suitable experimental animal model. We have looked into two animal models which can be conveniently used in large numbers for statistical analysis of effects of hemoperfusion on survival. One is carbon tetrachloride induced fulminant hepatic failure (1); another is the galactosamine induced fulminant hepatic failure rat model (2,3,4). These models seem to fulfill many of the requirements such as severe fulminant hepatic failure, reversibility and safety for research personnel. However, these animal models have not yet been used for the assessment of the effectiveness of treatment regimes for fulminant hepatic failure. Hemoperfusion has been used for patients with hepatic coma (5–13). The original finding (5,6) of hemoperfusion resulting in improvements of consciousness in grade 4 hepatic coma patients have now been supported by all centers. However, the effects on hemoperfusion in the improvements of long-term survival is not yet conclusive. For this, studies of a large series including rigid control studies is required. This is not too feasible in acute fulminant hepatic failure because of relatively small numbers of patients and the variations due to etiology, age, grade of coma and other factors.
