Effect of artificial liver support system on patients with severe viral hepatitis： A study of four hundred cases

AIM: To assess the effect of artificial liver support system (ALSS) on patients with severe viral hepatitis, who were divided into treatment group and control group. METHODS: Four hundred in-hospital patients enrolled during 1995-2003 who received ALSS therapy were studied as the treatment group. Four hundred in-hospital patients enrolled during 1986-1994 who received other medical therapies served as the control group. The methods of ALSS used included plasma exchange, hemoperfusion, hemofiltration, continuous hemodiafiltration (CHDF). The effect of ALSS treatment was studied in patients at different stages of the disease. RESULTS: The cure rate of acute and subacute severe hepatitis in the treatment group was 78.9% (30/38), and was 11.9% (5/42) in the control group. The improved rate of chronic severe hepatitis in the treatment group was 43.4% (157/362), and was 15.4% (55/358) in the control group. We found that patients treated with ALSS in the early or middle stage of the disease had much higher survival rates than patients in the end stage of the disease. CONCLUSION: ALSS is an effective and safe therapy for severe viral hepatitis.

Abstract：

Objective To investigate the effects of artificial liver support system(plasma exchange combined with continuous veno - venous hemodiafiltration, PE + CVVHDF) on Gc globulin in patients with liver failure. Methods 81 patients with liver failure were divided into 4 groups according to the treatment protocols and indicators such as liver function and clinical symptoms. Totally 29 effective cases and 14 ineffective cases in the ALSS group versus 15 effective cases and 23 ineffective cases in the medical group were included. Finally the changes of Gc globulin were observed in four subgroups before and after treatment.The correlation between Gc globulin and IL-10, IL-4, IL-18, TNF c, endotoxin, NO, sVCAM-land sICAM-1 were analyzed by Pearson correlation analysis. Results The effectiveness rate was 67.44% in ALSS group and 34.21% in the medical treatment (P ＜ 0.01). Gc globulin, one of liver cell protection proteins was notably increased following the artificial liver treatment as compared with the increase in the medical treatment (P ＜0.01). The time-response curve of Gc globulin level had a significant upward trend in the effective group as compared to no significant rise in the ineffective group. Moreover, the Gc globulin was negatively correlated with IL-4, IL-18, TNFα, SVCAM-1, SICAM-1 and NO. In contrat, no correlation existed between Gc globulin and IL-10. Conclusion The treatment with artificial liver can improve the outcome of the patients with liver failure. The level of Gc globulin was correlated with the curative effect and thus may be used as a potential indicator for curative effect forcast in the patients with liver failure.     

Artificial liver support system in China: a review over the last 30 years

Severe viral hepatitis with high mortality is the most common cause of liver failure in China. Treatment of severe viral hepatitis by hemoperfusion was initially adopted in the late 1970s and early 1980s. Following 10 years of development in China, a plasma exchange (PE)-centered artificial liver support system (ALSS), principally dependent on PE technology was developed. Based on the condition and symptoms of each patient, PE was given alone, or combined with hemodialysis, hemofiltration, hemodiafiltration, hemoperfusion, or plasma perfusion. In the late 1990s, training courses for ALSS were developed, and ALSS began to be carried out across China. Guidelines for artificial liver therapy were formulated and published by the Artificial Liver and Liver Failure Group of the Chinese Society of Infection. In recent years, new methods have been attempted, including small pore-size plasma separators, a molecular adsorbent-based recirculating system (MARS), and a continuous albumin purification system (CAPS). According to a retrospective analysis published in 2004, ALSS therapy significantly (P < 0.001) improved the survival rate of patients with severe hepatitis compared with patients who received only medicines (43.4%, 157/362 vs. 15.4%, 55/358 in chronic patients and 78.9%, 30/38 vs. 11.9%, 5/42 in acute and subacute patients). Furthermore, ALSS has also proved valuable as a bridge to liver transplantation in the treatment of patients with end-stage severe hepatitis in China. More recently, ALSS has been used in the treatment of drug-induced liver failure, acute fatty liver during pregnancy, and other difficult-to-treat disorders in China.     

Comparison scoring model of severe viral hepatitis and model of end stage liver disease for the prognosis of patients with liver failure in China

AIM:To estimate the prognosis of patients with liver failure using a scoring model of severe viral hepatitis (SMSVH) and a model of end stage liver disease (MELD) to provide a scientific basis for clinical decision of treatment. METHODS:One hundred and twenty patients with liver failure due to severe viral hepatitis were investigated with SMSVH established. Patients with acute,subacute,and chronic liver failure were 40,46 and 34,respectively. The follow-up time was 6 mo. The survival rates of patients with liver failure in 2 wk,4 wk,3 mo and 6 mo were estimated with Kaplan-Meier method. Comparison between SMSVH and MELD was made using ROC statistic analysis. RESULTS:The survival curves of group A (at low risk,SMSVH score ≤ 4) and group B (at high risk,SMSVH score ≥ 5) were significantly different (The 4-wk,3-mo,6-mo survival rates were 94.59%,54.05%,43.24% in group A,and 51.81%,20.48%,12.05% in group B,respectively,P < 0.001). The survival curves of group C (SMSVH scores unchanged or increased),group D (SMSVH scores decreased by 1) and group E (SMSVH scores decreased by 2 or more) were significantly different .The survival rates of groups C,D and E were 66.15%,100%,100% in 2-wk; 40.0%,91.18%,100% in 4-wk; 0%,58.82%,80.95% in 3-mo and 0%,38.24%,61.90% in 6-mo,respectively,P < 0.001). The area under the ROC curve (AUC) of SMSVH scores at baseline and after 2 wk of therapy was significantly higher than that under the ROC curve of MELD scores (0.804 and 0.934 vs 0.689,P < 0.001). CONCLUSION:SMSVH is superior to MELD in theestimation of the prognosis of patients with severe viral hepatitis within 6 mo. SMSVH may be regarded as a criterion for estimation of the efficacy of medical treatment and the decision of clinical treatment.
