Objective To evaluate the efficacy of entecavir treatment on hepatitis B patients with acute-on-chronic liver failure. Methods Eighty-four hepatitis B patients with acute-on-chronic liver failure were treated with entecavir 0.5 mg daily and Other routine drugs. Another 99 hepatitis B patients with acute-on-chronic liver failure were treated with only routine drugs as control. The survival, liver functions, hepatitis B virus (HBV) DNA level, prothrombin time (PT) were observed. The survival rates of patients with early, middle or late stage of liver failure were analyzed. The comparison of rates were done using chi-square test. The numeration data were compared by t test. The survival rates were compared using Kaplan-Meier method. Results Among patients with early stage of acute-on-chronic liver failure, the survival rate in treatment group was 63.3% (31/49), which was significantly higher than that in control group (39.7%, 23/58) (χ2=5.923, P=0.015). Among patients with middle stage of acute-on-chronic liver failure, the surviral rate in treatment group was 63.0% (17/27), which was significantly higher than that in control group (35.1%, 13/37) (χ2=4.854, P=0.028). Among patients with late stage of acute-on-chronic liver failure, four out of eight cases survived in treatment group, while one out of four cases survived in control group. In patients with serum total hilirubin (TBil) level > 342 μmol/L, the survival rate was 56.0% in treatment group, which was significantly higher than that in control group (26.8%) (χ2=9.351,P=0.002). At week 4 of the treatment, the HBV DNA reduction in treatment group was 3. 95 lg copy/mL, which was higher than that in control group (1.78 lg copy/mL) (t=5.847, P=0.001). Conclusions Entecavir treatment could improve the survival rate of hepatitis B patients with early or middle stage of acute-on-chronic liver failure. And the further study with larger population is needed in patients with late stage of liver failure. In addition, entecavir therapy could also improve the survival rate of patients with TBil >342 μmol/L.

Objective To investigate the level of serum macrophage migration inhibitory factor (MIF) and its correlation with serum precollagen Ⅲ peptide (PⅢP) and tissue inhibitor of metalloproteinase (TIMP)-1 in patients with chronic hepatitis B (CHB) and hepatitis B virus (HBV)-related cirrhosis. Methods Forty-four CHB patients (hepatitis B group), 44 patients with HBV-related cirrhosis (cirrhosis group) and 30 healthy controls (control group) were enrolled in this study. The venous blood was collected and MIF level was detected by enzyme-linked immunosorbent assay (ELISA). Correlations between MIF and PⅢP, TIMP-1 were analyzed in observed groups. Comparison between groups was done using t test. The correlations between MIF level and alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), plasma thromboplastin antecedent (PTA), PⅢP and TIMP-1 were analyzed by rectilinear correlation. Results The levels of serum MIF, PⅢP and TIMP-1 in CHB group and cirrhosis group were all significantly higher than those in control group (t=12.87,5.28, 10.98,t=11.22,14.84,11.17;all P<0.05), while there were no significant differences between CHB group and cirrhosis group (t= -1.05,1.52,--2.07;all P>0.05). There was no correlation between MIF level and ALT, AST, TBil and PTA. MIF level in CHB patients with hepatitis B e antigen (HBeAg) positive and high viral load were both higher than that in patients with HBeAg negative and low viral load. MIF level was both positively correlated with PⅢP level in CHB group and cirrhosis group (r=0. 603, P<0.05 and r=0. 415, P<0. 05, respectively). MIF level was also positively correlated with TIMP-1 level in CHB group (r=0. 458, P<0.05), while not correlated in cirrhosis group (r=0. 210, P>0.05). Levels of PⅢP and T1MP-1 were both correlated in CHB group and cirrhosis group (r=0. 849, P< 0.05 and r=0. 424, P<0.05, respectively). Conclusions The levels of serum MIF are significantly increased both in patients with CHB and cirrhosis. The early production of MIF might be related with viral replication, but not with liver function. MIF participates in formations of hepatitis, liver fibrosis and cirrhosis, which could reflect the degree of liver cirrhosis.
