“Background and Aim:  Long-term trends of anti-hepatitis C virus (HCV) antibody titer and their associated factors in patients with sustained virological response (SVR) were investigated. Methods:  From May 1999 to July 2005, a total of 166 SVR consecutive patients (M/F: 86/80) were enrolled. Anti-HCV titer, samples to cut-off (S/CO) ratios, were measured with AxSYM HCV version 3.0. Their S/CO ratios were followed every 6 months after SVR and the patterns over time were identified by trajectory analyses. Changes of recombinant immunoblot assay (RIBA) pattern before treatment and end of follow-up were compared (n = 64). Results:  The mean duration of follow-up was 4.7 ± 1.5 years (median 4.3; range 3–9 years). The rates of S/CO

ratios decreased annually (P < 0.001). Two of them (1.2%) achieved seroreversion. Trajectory groups included lower pretreatment S/CO ratios (LAB, n = 83), rapid decrease (RD, n = 62) and slow decrease (SD, n = 21) groups. Comparing LAB to RD group, odds ratio (OR) of increased platelet count per 1 unit and interferon regimen was 1.12 (95% confidence interval [CI] 1.04–1.20) and 2.17 (95% CI 1.04–4.52) respectively. Comparing SD to LAB and RD groups, the OR of advanced fibrotic stage, using mild fibrotic stage as a reference, was 4.33 (95% CI 1.49–12.63). Reaction strength of all four RIBA bands decreased significantly at the end of follow-up. Conclusions:  Anti-HCV titers decreased annually during long-term follow-up after SVR. Higher VX-809 pretreatment platelet count, interferon regimen and mild fibrosis were associated with

decreased anti-HCV titers. However, only a few cases achieved seroreversion. All RIBA bands decreased significantly after long-term follow-up. “
“Background and Aims:  Chronic hepatitis B virus (HBV) infection is a major global health issue, and the prognosis of patients with HBV-associated acute-on-chronic hepatic failure (ACLF) is extremely poor. In this study, MCE the efficacy of lamivudine was investigated in patients with ACLF. The effects of HBV DNA load and its related factors on the prognosis were also further explored. Methods:  A matched retrospective cohort study using data on ACLF patients derived from our hospital database was conducted. One hundred and thirty patients receiving lamivudine were selected into the lamivudine treatment group with another 130 without lamivudine treatment studied as control. They were matched for sex, age and imaging finding with the lamivudine treatment group. All the patients were followed up for 3 months and the survival rates were compared. The influential factors on the mortality were studied by the Cox proportional hazards model. Results:  The cumulative survival rates of patients in the lamivudine group were higher than those of the control group (χ2 = 9.50, P = 0.0021). The mortality of patients in the high virus load group (71/95, 74.
