Entecavir treatment reduces hepatic events and deaths in chronic hepatitis B patients with liver cirrhosis.

UNLABELLED: Entecavir is a potent antiviral agent with high genetic barrier to resistance, hence it is currently recommended as first-line antiviral therapy for chronic hepatitis B (CHB). The aim of this study was to investigate the efficacy of entecavir on clinical outcomes and deaths. It was a retrospective-prospective cohort study based on two cohorts of patients. The entecavir cohort included consecutive CHB patients who had received entecavir 0.5 mg/day for at least 12 months. The historical control cohort included untreated patients recruited since 1997 who underwent routine clinical care. The primary outcome was the 5-year cumulative probability of hepatic events, defined as any cirrhotic complications, hepatocellular carcinoma (HCC), and/or liver-related mortality. A total of 1,446 entecavir-treated patients (72% men; age, 51 ± 12 years; follow-up, 36 ± 13 months) and 424 treatment-naïve patients (65% men; age, 41 ± 13 years; follow-up, 114 ± 31 months) were studied. Overall, there was no difference in hepatic events between the entecavir and control cohorts. Among patients with liver cirrhosis (482 entecavir-treated, 69 treatment-naïve), entecavir-treated patients had reduced risks of all clinical outcomes when compared with treatment-naïve patients with cirrhosis after adjusted for model for end-stage liver disease score: hepatic events (hazard ratio [HR], 0.51; 95% confidence interval [CI], 0.34-0.78; P = 0.002), HCC (HR, 0.55; 95% CI, 0.31-0.99; P = 0.049), liver-related mortality (HR, 0.26; 95% CI, 0.13-0.55; P < 0.001), and all-cause mortality (HR, 0.34; 95% CI, 0.18-0.62; P < 0.001). Entecavir-treated patients with cirrhosis who failed to achieve undetectable hepatitis B virus DNA (105/482 [22%]) had comparable risk of hepatic events as the untreated patients. CONCLUSION: Entecavir therapy reduces the risks of hepatic events, HCC, liver-related and all-cause mortality of CHB patients with liver cirrhosis in 5 years, particularly among those who had maintained viral suppression.

Community-based lifestyle modification programme for non-alcoholic fatty liver disease: a randomized controlled trial.

BACKGROUND & AIMS: Healthy lifestyle is the most important management of non-alcoholic fatty liver disease (NAFLD). This study aimed at assessing the efficacy of a community-based lifestyle modification programme in the remission of NAFLD. METHODS: This was a parallel group, superiority, randomized controlled trial. 154 adults with NAFLD identified during population screening were randomized to participate in a dietitian-led lifestyle modification programme at 2 community centres or receive usual care for 12 months. The primary outcome was remission of NAFLD at month 12 as evidenced by intrahepatic triglyceride content (IHTG) of less than 5% by proton-magnetic resonance spectroscopy. RESULTS: 74 patients in the intervention group and 71 patients in the control group completed all study assessments. In an intention-to-treat analysis of all 154 patients, 64% of the patients in the intervention group and 20% in the control group achieved remission of NAFLD (difference between groups 44%; 95% CI 30-58%; p<0.001). The mean (SD) changes in IHTG from baseline to month 12 were -6.7% (6.1%) in the intervention group and -2.1% (6.4%) in the control group (p<0.001). Body weight decreased by 5.6 (4.4) kg and 0.6 (2.5) kg in the two groups, respectively (p<0.001). While 97% of patients with weight loss of more than 10% had remission of NAFLD, 41% of those with weight loss of 3.0-4.9% could also achieve the primary outcome. CONCLUSIONS: The community-based lifestyle modification programme is effective in reducing and normalizing liver fat in NAFLD patients.

Prevention of hepatitis B virus reactivation in patients with hematological malignancies and resolved hepatitis B virus infection: a systematic review and meta-analysis.

OBJECTIVE: Patients with resolved hepatitis B virus (HBV) infection are at risk of HBV reactivation during treatment for hematological malignancies. We conducted a systematic review and meta-analysis of the data on the efficacy of antiviral prophylaxis for the prevention of HBV reactivation in this group of patients. METHODS: We conducted a systemic literature search of PubMed including MEDLINE and EMBASE databases to 31 January 2019 to identify studies published in English comparing antiviral prophylaxis with no prophylaxis for HBV reactivation in patients treated for hematological malignancies. The search terms used were ("occult hepatitis B" OR "resolved hepatitis B") AND ("reactivation") AND ("haematological malignancy" OR "hematological malignancy" OR "chemotherapy" OR "immunotherapy" OR "chemoimmunotherapy" OR "lymphoma" OR "leukemia" OR "transplant"). The primary outcome was the reactivation of HBV infection. Pooled estimates of relative risk (RR) were calculated. RESULTS: We identified 13 relevant studies including two randomized controlled trials (RCT), one post hoc analysis from RCT and 10 cohort studies. There was a trend towards a lower rate of HBV reactivation using antiviral prophylaxis, but the difference was not significant (RR 0.57, 95% confidence interval [CI] 0.23-1.40, P = 0.22). When limiting the analysis to the three prospective studies of patients receiving anti-CD20 monoclonal antibodies, we found antiviral prophylaxis was associated with a significantly lower risk of HBV reactivation (RR 0.17, 95% CI 0.06-0.49, P = 0.001). CONCLUSION: Antiviral prophylaxis reduced the risk of HBV reactivation in patients receiving anti-CD20 monoclonal antibodies for hematological malignancies but not in a broader group of patients receiving anticancer therapy.
