BACKGROUND: Acute liver failure (ALF) caused by viral and non-viral hepatitis is often accompanied with severe metabolic disorders, the accumulation of toxic substances and continuous release and accumulation of a large number of endogenous toxins and inflammatory mediators. The present study aimed to investigate the effects of various combined non-biological artificial liver treatments for patients with acute liver failure (ALF) complicated by multiple organ dysfunction syndrome (MODS). METHODS: Thirty-one patients with mid-or late-stage liver failure complicated by MODS (score 4) were randomly divided into three treatment groups: plasmapheresis (PE) combined with hemoperfusion (HP) and continuous venovenous hemodiafiltration (CVVHDF), PE+CVVHDF, and HP+CWHDF, respectively. Heart rate (HR) before and after treatment, mean arterial pressure (MAP), respiratory index (PaO2/FiO(2)), hepatic function, platelet count, and blood coagulation were determined. RESULTS: Significant improvement was observed in HR, MAP, PaO2/FiO(2), total bilirubin (TBIL) and alanine aminotransferase (ALT) levels after treatment (P<0.05). TBIL and ALT decreased more significantly after treatment in the PE+CVVHDF and PE+HP+CVVHDF groups (P<0.01). Prothrombin time (PT) and albumin were significantly improved only in the PE+CVVHDF and PE+HP+CVVHDF groups (P<0.05). TBIL decreased more significantly in the PE+HP+CVVHDF group than in the HP+CVVHDF and PE+CVVHDF groups (P<0.05). The survival rate of the patients was 58.1% (18/31), viral survival rate 36.4% (4/11), and non-viral survival rate 70% (14/20). CONCLUSION: Liver function was relatively improved after treatment, but PE+HP+CVVHDF was more efficient for the removal of toxic metabolites, especially bilirubin. The survival rate was significantly higher in the patients with non-viral liver failure than in those with viral liver failure.
