Objective To evaluate the long-term prognosis of patients with HBV-related decompensated cirrhosis after treatment with nucleos (t) ide analogues. Methods Totally 94 patients with HBV-related decompensated cirrhosis were enrolled, 53 in nucleos(t) ide group, 41 in control group, and both received routine treatments. Patients in nucleos (t)ide analogue group also received lamivudine ( 100 mg/d), or adefovir ( 10 mg/d), or entecavir (0.5 rag/d). The follow-up was terminated for those who developed hepatocellular carcinoma, received liver transplantation, died or refused the treatment. Serum biochemical markers, Child-Pugh grades and clinical outcomes were compared between two groups at the end of following up. Results After nucleos (t) ide analogues therapy, ALT, AST, globulin ( Glb), and TBil decreased, while Alb and cholinesterase (CHE) increased in the nucleos(t)ide group, and Chiid-Pugh scores decreased in 43 (81.1%) patients. While in the control group, ALT, AST, Glb and TBil did not show significant changes, but the CHE was significantly lower than before ( t = 5. 225, P < 0. 01 ). More patients in nucleos (t)ide group showed improvements in Child-Pugh grades, and there was significant difference between the two groups (X2 = 52.16, P <0.01). The incidence of HCC is lower in nucleos(t) ide group (0%) than that in the control group ( 19.5% ) ( X2 = 23.07, P < 0.01 ). The incidence of death and liver transplantation between two groups did not show siguificant difference. Conclusions Nucleos(t) ide analogues therapy can significantly improve biochemical status of liver functions in patients with HBV-related decompensated cirrhosis. The incidence of hepatocellular carcinoma may decline and the long-term prognosis can be improved.

Objective To investigate the risk factors of hepatitis B virus(HBV) re-infection after orthotopic liver transplantation(OLT)and to evaluate the therapeutic efficacy of hepatitis B immunoglobulin(HBIG)combined with nucleos(t)ide analogues. Methods The study included 160 patients with HBVrelated liver diseases who underwent OLT in the Third Affiliated Hospital of Sun Yat-sen University from October 2003 to Augest 2007, 117 of whom were treated with nucleos(t)ide analogues before OLT;and all patients were received HBIG i. m and nucleos(t)ide analogues treatment after OLT. Preoperative data of the patients were retrospectively reviewed, and HBV re-infection was assessed prospectively. Independent t test was used to compare normally distributed data and Fisher's exact test was used for the comparison of rates among groups. Results HBV re-infection Was observed in 19 patients after OLT with a rate of 11. 88%(19/160), which was not correlated with HBV DNA loads, HBeAg and the duration of antiviral therapy before OLT(r=0.108, 0.127 and 0.033, P>0.05). Of 19 patients with HBV re-infection, 17 were treated with lamivudine after OLT, and HBV YMDD mutants were detected in 8. The YMDD positive group had a higher HBV DNA level than YMDD negative group(7.0 ± 2.0 log copies/mL vs 3.2 ± 2.5 log copies/mL, t = 3.531, P=0.003). Among above 17 patients, 12 received adefovir add-on treatment, and3 received entecavir instead of lamivadine; all achieved satisfactory responses. Conclusions Low dose of HBIG combined with long-term use of nucleos(t)ide analogues can effectively prevent HBV re-infection after OLT. HBV YMDD mutation may be the primary reason for HBV re-infection in the patients treated with lamivudine after OLT.

Objective To establish a scoring system for evaluating the severity of hepatitis B patients with acute-on-chronic liver failure and to compare the validity of this system with model for end-stage liver disease (MELD). Methods MELD score was used in hepatitis B patients with acuteon-chronic liver failure who were divided into survival group (203 cases) and death group (196 cases).Seven clinical relative indices, including prothrombin activity, serum creatinine, hepatic encephalopathy, accompanying infections, serum total bilirubin, the dimension of liver, the amount of ascites, were selected for evaluating the severity. Each index was graded with 1 to 4 points based on the severity. Then the total score was counted by adding up scores of each index. T test and area under receiver operating characteristic (ROC) were used to evaluate the difference and similarity of the two systems. Results According to the new scoring system, the total score was 8. 07±3. 14 in the survival group and 16. 91 ±3. 54 in the death group. There was a statistically significant difference between these two groups (t = 26.125. P<0.01). In 81.32% of survival patients, their scores ranged from 3.91 to 12.23, while in 81.32% of dead patients, their scores ranged from 12.23 to 21.60. The two ranges overlapped at 12.23. According to the MELD system, the total score was 26. 43 ±5. 58 in the survival group and 40. 16 ±10. 22 in the death group. The difference between the two groups was statistically different (t = 16. 566, P<0. 01). In 61.02% of survival patients, the MELD scores ranged from 21. 49 to 31. 19, while in 61. 02% of the dead patients, the MELD scores ranged from 31. 19 to 48. 94. The two ranges overlapped at 31.19. The areas under ROC of the new scoring system and MELD system were 0.960 (95% CI: 0. 944-0. 977) and 0.886 (95% C/;0. 852 - 0. 920). No overlap was found in these two 95%CJ and there was a statistically significant difference. Conclusions The new scoring system is applicable for evaluating the severity and prognosis of acute-on-chronic liver failure in hepatitis B patients. The sensitivity of this new scoring system is approximate to the MELD system.
