The control group received continuous venous-venous hemofiltration(CVVH) on the basis of conventional treatments, and the therapeutic dose of CVVH was 30 m L/kg per hour. The study group received sequential plasma exchange and CVVH on the basis of conventional treatments. The anticoagulation regimen of CVVH is the regional citrate anticoagulation. Mortality rate on day 28, rates of systemic and local complications, duration of ICU, and time to target serum lipid level, as well as physiologic and laboratory indices were compared between the two groups.RESULTS: The mortality rate on day 28 was significantly lower in the study group than in the control group(13.33% vs 37.50%; P < 0.05). The duration of ICU stay was significantly shorter in the study group than in the control group(7.4 ± 1.35 d vs 9.19 ± 2.99 d, P < 0.05). The time to target serum lipid level was significantly shorter in the study group than in the control group(3.47 ± 0.52 d vs 7.90 ± 1.14 d, P < 0.01). There were no significant differences in the rates of systemic complications and local complications between the two groups(60% vs 50% and 80% vs 81%, respectively). In the comparisons of physiologic and laboratory indices, serum albumin and C-reactive protein were significantly better in the study group than in the control group after treatment(37.8 ± 4.6 g/L vs 38.9 ± 5.7 g/L, and 20.5 ± 6.4 mg/L vs 28.5 ± 7.1 mg/L, respectively, both P < 0.05).

The present study aimed to investigate the effects of various combined non-biological artif icial 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+CVVHDF,respectively. Heart rate(HR) before and after treatment,mean arterial pressure(MAP),respiratory index(PaO2/FiO2),hepatic function,platelet count,and blood coagulation were determined.RESULTS:Signifi cant improvement was observed in HR,MAP,PaO2/FiO2,total bilirubin(TBIL) and alanine aminotransferase(ALT) levels after treatment(P<0.05). TBIL and ALT decreased more signifi cantly after treatment in the PE+CVVHDF and PE+HP+CVVHDF groups(P<0.01). Prothrombin time(PT) and albumin were signifi cantly 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 signifi cantly higher in the patients with non-viral liver failure than in those with viral liver failure.展开更多

Its traditional therapy is not very effective in facilitating hepatic recovery. The safety and effect of plasma exchange (PE)in combination with continuous renal replacement therapy(CRRT) (PE+CRRT) for AFLP still needs evaluation.METHODS: Five AFLP patients with hepatic encephalopathy and renal failure were subjected to PE+CRRT in our department from 2007 to 2012. Their symptoms, physical signs and results were observed, and all relevant laboratory tests were compared before and after PE+CRRT.RESULTS: All the 5 patients were well tolerated to the therapy. Four of them responded to the treatment and showed improvement in clinical symptoms/signs and laboratory results and they were cured and discharged home after the treatment One patient succeeded in bridging to transplantation for slowing down hepatic failure and its complications process after2 treatment sessions. Intensive care unit stay and hospital stay were 9.4 (range 5-18) and 25.0 days (range 11-42), respectively.CONCLUSION: PE+CRRT is safe and effective and should be used immediately at the onset of hepatic encephalopathy and/or renal failure in patients with AFLP.展开更多

Plasma exchange (PE) has been found useful in treating patients with fulminant hepatic failure by removing hepatic toxins and replacement of clotting factors, so PE treatment has temporary supportive effects on liver failure caused by severe viral hepatitis. in this study, our aim was to predict the prognosis of patients with severe hepatitis after PE treatment using the end-stage liver disease (MELD) scoring system. METHODS: Two hundred and twenty patients were randomly divided into PE and control groups, and the MELD score was calculated for each patient according to the original formula. The efficacy of PE was assessed by mortality or improvement in biochemical parameters and MELD score. RESULTS: The levels of total bilirubin and international normalised ratio (INR) in patients whose MELD scores were between 30 and 39 were lower than those before PE treatment, as those in patients whose MELD scores were 40 or higher. The mortality of patients in the PE group with MELD scores from 30 to 39 was 50.0%, while it was 83.3% in the control group (P<0.01). The mortality of patients with MELD scores higher than 40 was 90.0% in the PE group and 98.0% in the control group (P>0.05). CONCLUSIONS: PE treatment can decrease the serum total bilirubin level and INR and MELD score of patients with severe hepatitis and improve liver function. Compared with the control group, PE can significantly decrease the mortality of patients with MELD scores from 30 to 39, but has no effect in patients with MELD scores of 40 or higher.展开更多
