    Abstract

    BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease worldwide. Asia is a large, heterogeneous area with substantial variation in socioeconomic status and prevalence of obesity. We estimated the prevalence, incidence, and outcomes of NAFLD in the Asian population to assist stakeholders in understanding NAFLD disease burden.METHODS: We searched PubMed, EMBASE, and the Cochrane Library from database inception to Jan 17, 2019, for studies reporting NAFLD prevalence, incidence, or outcome in Asia. We included only cross-sectional and longitudinal observational studies of patients with NAFLD diagnosed by imaging, serum-based indices, or liver biopsy. Studies that included patients with overlapping liver disease or that did not screen for excess alcohol consumption were excluded. Two investigators independently screened and extracted data. The main outcomes were pooled NAFLD prevalence, incidence, and hepatocellular carcinoma incidence and overall mortality in patients with NAFLD. Summary estimates were calculated using a random-effects model. This study is registered with PROSPERO, number CRD42018088468.FINDINGS: Of 4995 records identified, 237 studies (13 044 518 participants) were included for analysis. The overall prevalence of NAFLD regardless of diagnostic method was 29·62% (95% CI 28·13-31·15). NAFLD prevalence increased significantly over time (25·28% [22·42-28·37] between 1999 and 2005, 28·46% [26·70-30·29] between 2006 and 2011, and 33·90% [31·74-36·12] between 2012 and 2017; p<0·0001). The pooled annual NAFLD incidence rate was 50·9 cases per 1000 person-years (95% CI 44·8-57·4). In patients with NAFLD, the annual incidence of hepatocellular carcinoma was 1·8 cases per 1000 person-years (0·8-3·1) and overall mortality rate was 5·3 deaths per 1000 person-years (1·5-11·4).INTERPRETATION: NAFLD prevalence in Asia is increasing and is associated with poor outcomes including hepatocellular carcinoma and death. Targeted public health strategies must be developed in Asia to target the drivers of this rising epidemic and its associated complications, especially in high-risk groups, such as older obese men.FUNDING: None.

    Abstract

    One-third of the global hepatitis C virus (HCV) burden is found in Asia. Real-world data from diverse East Asian cohorts remain limited. This study addressed the real-world status of direct-acting antiviral (DAA) therapy among patients from East Asia.Chronic hepatitis C (CHC) patients from clinical sites in Japan, Taiwan, South Korea, and Hong Kong were recruited in the REAL-C registry, an observational chart review registry. The primary outcome was sustained virologic response (SVR12, HCV RNA PCR < 25 IU/mL 12 week post-therapy).A total of 6287 CHC patients were enrolled. Compared to other East Asian patients, patients from Japan were older (66.3 vs. 61.5 years, p < 0.0001), had lower body mass indices (22.9 kg/m2 vs. 24.6 kg/m2, p < 0.001), and were more likely to have non-liver malignancy history (12.2% vs. 5.0%, p < 0.001).The overall SVR12 rate was 96.4%, similar to patients both inside and outside Japan (96.6% vs. 96%, p = 0.21). The SVR12 rate ranged from 91.1 to 99.4% except treatment-experienced cirrhotic HCV genotype-1 patients who received daclatasvir/asunaprevir (85.9%) and the treatment-experienced cirrhotic HCV genotype-2 patients treated with sofosbuvir/ribavirin (87%). The overall rate of drug discontinuation was 1.9%, also similar across regions. On multivariate regression analyses, there was no significant association between geographic region and SVR outcomes.In this large multinational CHC cohort from the East Asia, oral DAAs were highly effective and well tolerated across the region. Policies should encourage treatment for all CHC patients with DAAs in Asia with its heavy burden of HCV.

  • Factors Associated with Rates of HBsAg Seroclearance in Adults with Chronic HBV Infection: A systematic review and meta-analysis. Gastroenterology Yeo, Y. H., Ho, H. J., Yang, H. I., Tseng, T.

    Abstract

    Seroclearance of hepatitis B surface antigen (HBsAg) is a marker for clearance of chronic hepatitis B virus (HBV) infection but reported annual incidence rates of HBsAg seroclearance vary. We performed a systematic review and meta-analysis to provide more precise estimates of HBsAg seroclearance rates among subgroups and populations.We searched PubMed, Embase, and Cochrane library for cohort studies that reported HBsAg seroclearance in adults with chronic HBV infection with more than 1 year of follow up and at least 1 repeat test for HBsAg. Annual and 5-, 10-, and 15-year cumulative incidence rates were pooled using a random effects model.We analyzed 34 published studies (with 42,588 patients; 303,754 person-years of follow-up; and 3194 HBsAg seroclearance events), including additional and updated aggregated data from 19 studies. The pooled annual rate of HBsAg seroclearance was 1.02% (95% CI, 0.79-1.27). Cumulative incidence rates were 4.03% at 5 years (95% CI, 2.49-5.93), 8.16% at 10 years (95% CI, 5.24-11.72), and 17.99% at 15 years (95% CI, 6.18-23.24). There were no significant differences between sexes. A higher proportion of patients negative for HBeAg at baseline had seroclearance (1.33%; 95% CI, 0.76-2.05) than patients positive for HBeAg (0.40%; 95% CI, 0.25-0.59) (P<.01). HBsAg seroclearance was also associated with a lower baseline HBV DNA (6.61 log10IU/mL; 95% CI, 5.94-7.27) than in patients without HBsAg seroclearance (7.71 log10IU/mL; 95% CI, 7.41-8.02) (P<.01) and lower level of HBsAg at baseline (2.74 log10IU/mL; 95% CI, 1.88-3.60) than in patients without HBsAg seroclearance (3.90 log10IU/mL, 95% CI, 3.73-4.06) (P<.01). HBsAg seroclearance was not associated with HBV genotype or treatment history. Heterogeneity was substantial across the studies (I2=97.49%).In a systematic review and meta-analysis, we found a low rate of HBsAg seroclearance in untreated and treated patients (pooled annual rate approximately 1%). Seroclearance occurred mainly in patients with less active disease. Patients with chronic HBV infection should therefore be counseled on the need for lifelong treatment, and curative therapies are needed.
