Abstract
The impact of concurrent fatty liver (FL) on response to antiviral therapy in chronic hepatitis B (CHB) patients has not been well characterized. We aimed to systematically review and analyse antiviral treatment response in CHB patients with and without FL. We searched PubMed, Embase, Web of Science and the Cochrane Library databases from inception to 31 May 2023 for relevant studies. Biochemical response (BR), complete viral suppression (CVS) and hepatitis B e antigen (HBeAg) seroconversion in CHB patients with FL (CHB-FL) and without FL (non-FL CHB) were compared. In an initial pool of 2101 citations, a total of 10 studies involving 2108 patients were included. After 12 weeks of treatment, CHB-FL patients as compared with non-FL CHB patients had lower BR rate (48.37% [108/227] vs. 72.98% [126/174], p = .04) but similar trend for CVS (36.86% [80/227] vs. 68.81% [114/174], p = .05) and similar rates of HBeAg seroconversion (6.59% [7/103] vs. 7.40% [7/110], p = .89). However, at week 48, there were no statistically significant differences between CHB-FL and non-FL CHB patients in any of the outcomes, including BR (60.03% [213/471] vs. 69.37% [314/717], p = .67), CVS (65.63% [459/746] vs. 73.81% [743/1132], p = .27) and HBeAg seroconversion (10.01% [30/275] vs. 14.06% [65/453], p = .58) with similar findings for week 96. BR rate was lower in CHB-FL patients after 12 weeks of antiviral treatment. However, after a longer follow-up of either 48 or 96 weeks, no statistically significant differences were observed in BR, CVS or HBeAg seroconversion rates between CHB patients with and without FL.

Abstract
Background & Aims The vast majority of studies evaluating differences in on-treatment risks of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B (CHB) have been conducted in Asia. Data on the course of CHB on antiviral therapy among predominantly non-Asian populations is less well described. We aimed to evaluate overall risks of cirrhosis and HCC and the influence of baseline factors on this risk among a predominantly non-Asian cohort of patients with CHB in the US. Methods Using longitudinal data from the national Veterans Affairs database, we evaluated the incidence of cirrhosis or HCC among adults with non-cirrhotic CHB on continuous antiviral therapy. Cumulative incidence functions and adjusted Cox proportional hazards models employed competing risks methods and evaluated overall risk and predictors of developing cirrhosis or HCC while on treatment. Results Among 2,496 patients with non-cirrhotic CHB (39.1% African American, 38.4% non-Hispanic White, 18.8% Asian, mean age 58.0 ± 13.4 years), the overall incidences of cirrhosis and HCC were 3.99 per 100 person-years (95% CI 3.66-4.35) and 0.43 per 100 person-years (95% CI 0.33-0.54), respectively. The highest incidences of cirrhosis and HCC were observed in non-Hispanic White patients (5.74 and 0.52 per 100 person-years, respectively), which were significantly higher than in Asian patients (1.93 and 0.17 per 100 person-years, respectively, p <0.0001). On multivariate regression, only baseline FIB-4 score was consistently associated with long-term risk of cirrhosis or HCC. Conclusions Using a longitudinal cohort of predominantly non-Asian Veterans with non-cirrhotic CHB on antiviral therapy (an understudied population), we provide important epidemiological data to describe long-term risks of cirrhosis and HCC. Impact and implications In one of the largest studies to date of a predominantly non-Asian cohort of patients with non-cirrhotic chronic hepatitis B, we provide important epidemiological data describing the long-term risks of cirrhosis and hepatocellular carcinoma among patients on antiviral therapies. Among this understudied population, the overall incidence of cirrhosis was 3.99 per 100-person-years (95% CI 3.66-4.35) and of HCC was 0.43 per 100-person-years (95% CI 0.33-0.54). These data also emphasize the importance of continued monitoring and HCC surveillance among CHB patients who are maintained on antiviral therapies.

Abstract
BACKGROUND & AIMS Serum-based noninvasive tests (NITs) have been widely used to assess liver fibrosis in patients with nonalcoholic fatty liver disease (NAFLD). However, the diagnostic efficacy of NITs across ranges of age, body mass index (BMI), and presence of type 2 diabetes (T2DM) may vary and have not been well-characterized. METHODS We analyzed 1489 patients with biopsy-proven NAFLD from 6 centers in Japan, Taiwan, and Korea. Using histology as the gold standard, we compared the areas under the receiver operating characteristic (AUROCs) of Fibrosis-4 index (FIB-4), NAFLD fibrosis score (NFS), and the new Hepamet fibrosis score (HFS), with a focus on performance in subgroups as stratified by age, BMI, and the presence of T2DM. RESULTS By histology, 44.0% of the overall cohort (655/1489) had F2-4, and 20.6% (307/1489) had F3-4 fibrosis. FIB-4 had the highest AUROCs for both F2-4 (0.701 vs NFS 0.676 and HFS 0.682, P = .001) and F3-4 (0.767 vs NFS 0.736 and HFS 0.752, P = .002). However, for F3-4 fibrosis, the AUROCs of all 3 NITs were generally higher in older (>60 years), nonobese (BMI <25 kg/m2), and non-diabetic patients, although overall the best performance was observed with FIB-4 among nonobese (BMI<25) diabetic patients (AUROC, 0.92). The worst performance was observed in younger patients with T2DM for all NITs including FIB-4 (AUROC, 0.63-0.66). CONCLUSIONS FIB-4 had higher diagnostic efficacy for F3-4 than NFS or HFS, but this varied greatly by age, BMI, and T2DM, with better performance in older, nonobese, and nondiabetic patients. However, all NITs including FIB-4 had unacceptably poor performance in young or obese diabetic patients.

Abstract
INTRODUCTION NAFLD is increasingly prevalent in Asia, where people suffer more metabolic comorbidities at a lower body mass index (BMI), suggesting potential differences in their clinical profile. Therefore, we attempted to characterize the clinical profile of Asians with NAFLD via a meta-analytic approach. METHODS We searched PubMed, EMBASE, and Cochrane databases from January 1, 2000, to January 17, 2019. Two authors independently reviewed and selected 104 articles (2,247,754 persons) that identified NAFLD in Asians and reported relevant data, especially BMI and ALT, and excluded individuals with other liver disease and excessive alcohol consumption. Individual patient-level data were obtained from seven cohorts in Asia to complement meta-analyzed data. RESULTS Overall, the mean age was 52.07 (95% CI: 51.28-52.85) years, with those from Southeast Asia (42.66, 95% CI: 32.23-53.11) being significantly younger. The mean BMI was 26.2 kg/m2, higher in moderate-severe versus mild hepatic steatosis (28.3 vs. 25.7) patients and NFS ≥ -1.455 versus <-1.455 (27.09 vs. 26.02), with 34% having nonobese NAFLD. The mean ALT was 31.74 U/L, higher in NFS < -1.455 versus ≥-1.455 (33.74 vs. 27.83), though no differences were found by obesity or steatosis severity. The majority of males (85.7%) and females (60.7%) had normal to minimally elevated ALT (1-1.5 × 95% ULN). Individual patient-level data analysis (N = 7,668) demonstrated similar results. CONCLUSION About one-third of Asians with NAFLD were nonobese, and the majority did not have markedly elevated ALT. Therefore, abnormal ALT or BMI is not recommended as a criterion for NAFLD screening in this population. Additionally, there were significant differences in the clinical profiles of NAFLD among the different regions of Asia.

Abstract
INTRODUCTION Chronic hepatitis B (CHB) patients with metabolic syndrome (MetS) may present increased risk of liver-related outcomes (LROs), but prior studies were limited by small sample size and/or conflicting results. Using a systematic review and meta-analytic approach, we aimed to determine the association between MetS and LROs in CHB. METHODS Two researchers independently screened studies from the PubMed, Embase, Web of Science, and Cochrane Library databases from inception to January 21, 2020, and extracted the data. Estimates were pooled using a random-effects model. RESULTS We screened 2,228 articles and included 10 eligible studies (18,360 CHB patients, 2,557 with MetS). MetS was significantly associated with LROs overall (odds ratio = 2.45, 95% confidence interval = 1.39-4.32) but not the individual LRO components but subgroup analyses were limited by small study numbers. DISCUSSION/CONCLUSION MetS is associated with almost 3-folds higher risk of LROs in CHB and should be considered in management decisions. However, additional studies are needed.

Abstract
BACKGROUND NAFLD incidence, NASH prevalence, NAFLD fibrosis prevalence, incidence of metabolic comorbidities, and mortality data in the NAFLD population remain limited. AIMS We used a meta-analytic approach to "stage" NAFLD among the Korean population. METHODS We searched PubMed, Embase, Cochrane Library, and KoreaMed from inception until June 29, 2019, and calculated pooled estimates via the random-effects model. RESULTS We screened 1,485 studies and analyzed 191 eligible studies: 179 (3,556,579 participants) for NAFLD prevalence and outcome analysis and 32 (1,089,785 participants) for NAFLD incidence analysis. NAFLD prevalence was 31.46% overall and 50-60% in those with metabolic risks. The incidence (per 1,000 person-years) of NAFLD was 42.8 overall and 70-77% in those with metabolic risk. The incidence (per 1,000 person-years) of new-onset T2DM, hypertension, cardiovascular disease, and chronic kidney disease was found to be 16.9, 47.9, 100.6, and 13.9, respectively. From biopsy data, 30.21% of the NAFLD population had moderate-to-severe steatosis (9 studies, 2,461 participants) and 52.27% had NASH (7 studies, 1,168 participants) and 85.41% had fibrosis <stage 2 (8 studies, 1,995 participants). All-cause mortality was 2.6 (1.3 if without malignancy) per 1,000 person-years. CONCLUSIONS The overall prevalence of NAFLD was 31.46% with an incidence rate of 42.8 per 1,000 person-years. NASH prevalence was 52% but <15% had significant fibrosis. The prevalence and incidence of nonliver comorbidities was high especially for cardiovascular disease incidence. The burden of NAFLD is high in Korea. Health policy efforts need to be directed towards reversing the course of NAFLD disease.

Abstract
BACKGROUND As the prevalence of hepatitis steatosis (HS) increases, the prevalence of HS among those with chronic hepatitis B (CHB) may also be increasing but data on the effect of HS on CHB disease progression are lacking. AIMS To determine the prevalence of HS in CHB and associated factors, prevalence of fibrosis and its association with HS. METHODS Two researchers independently searched the literature and extracted data. We included full-length original articles of adults with CHB that evaluated. Prevalence estimates were pooled using a random-effects model. Associations between HS and fibrosis were assessed by pooled odds ratios (ORs) or mean differences (MD). RESULTS Of the 2821 records screened, 54 eligible studies (28 648 patients) were analysed. The pooled prevalence of HS in CHB was 32.8% (95% CI, 28.9-37.0) with higher prevalence in men and obese patients. Older age, male sex and metabolic factors were associated with HS while an inverse association was observed between HS and HBeAg (OR 0.82, 95% CI, 0.75-0.91) and HBV DNA levels (MD -0.38, 95% CI -1.16--0.42). The pooled prevalence of significant fibrosis (≥F2 or ≥F3) was similar between patients with CHB with or without HS (40.1% vs 42.22%, P = 0.68). HS was not significantly associated with fibrosis (pooled OR 0.87, 95% CI 0.54-1.39, 20 studies, 6232 patients). CONCLUSIONS Approximately 30% of patients with CHB had HS, which was positively associated with male sex, diabetes and metabolic factors, and was negatively associated with HBeAg and HBV DNA. HS was not significantly associated with increased fibrosis.

Abstract
BACKGROUND & AIMS Metabolic dysfunction-associated fatty liver disease (MAFLD) establishes new criteria for diagnosing fatty liver disease independent of alcohol intake and concomitant viral hepatitis infection. However, the long-term outcomes of patients with MAFLD are sparse. We aimed to describe the characteristics and long-term survival of persons meeting criteria for nonalcoholic fatty liver disease (NAFLD) only (non-MAFLD NAFLD), for both NAFLD and MAFLD (NAFLD-MAFLD), and for MAFLD only (non-NAFLD MAFLD). METHODS Using data from the Third National Health and Nutrition Examination Survey (NHANES III) 1988-1994, 2997 participants with fatty liver identified via ultrasound were categorized into 3 distinct groups: non-MAFLD NAFLD, NAFLD-MAFLD, and non-NAFLD MAFLD. RESULTS Participants in the NAFLD-MAFLD and non-NAFLD MAFLD groups were older, had more metabolic traits and higher mean liver enzymes. Nearly 8% of participants in the non-NAFLD MAFLD group had advanced fibrosis (Fibrosis-4 index >2.67), while only 1.3% and 1.9% in the NAFLD-MAFLD and non-MAFLD NAFLD groups did, respectively (P < .0001). Non-NAFLD MAFLD participants had the highest cumulative incidence of all-cause mortality (26.2%) followed by those with NAFLD-MAFLD then non-MAFLD NAFLD participants (21.1% and 10.6%, respectively; P < .0001). Similar findings were observed for cardiovascular disease-related and other-cause (noncardiovascular disease, noncancer) mortality. Non-NAFLD MAFLD was independently associated with all-cause mortality compared with non-MAFLD NAFLD (adjusted hazard ratio, 2.4; 95% confidence interval, 1.2-4.6; P = .01). CONCLUSIONS MAFLD criteria identified a significant group of people with more comorbidities and worse prognosis compared with those with NAFLD only. These criteria should be considered in the general population to identify high-risk groups for early interventions.

Abstract
BACKGROUND & AIMS The epidemiology of hepatitis B virus (HBV) infection differs between Asians and non-Asians, but little is known regarding the effect of ethnicity on outcomes of HBV-related hepatocellular carcinoma (HCC). We aim to characterize the presentation and survival outcomes in Asian and non-Asian patients with HBV-related HCC. METHODS We analyzed the baseline characteristics and long-term survival of 613 Asian and 410 non-Asian patients with HBV-related HCC from three US and one Spanish centre. RESULTS Overall, non-Asian patients were more likely to have HIV or hepatitis C co-infection, cirrhosis, decompensated liver disease and advanced BCLC stage (all P ≤ .04). Compared with Asians, non-Asians were more likely to be listed for transplantation (P < .0001) and undergo HCC treatment with curative intent (P = .003). Propensity-score matching on HCC diagnosis year, gender and age was performed to balance the two groups for survival analysis and yielded 370 pairs of patients. There was no significant difference in survival overall (P = .43) and among patients with cirrhosis (P = .57). Among patients without cirrhosis, non-Asians had poorer 5-year survival compared with Asians (37.6% vs 53.7%, P = .01), and was associated with poorer survival after adjusting for age, gender, diabetes, alcohol, co-infections, diagnosis date, antiviral therapy, BCLC stage and HCC treatment (adjusted HR 2.01 [95% CI 1.07-3.74], P = .03). CONCLUSION Among HBV-related HCC patients, non-Asians presented with more advanced BCLC stage compared to Asians. Non-Asian ethnicity was independently associated with twice the risk of mortality among patients without cirrhosis, but not among those with cirrhosis. Additional studies are needed to clarify this disparity.

Abstract
BACKGROUND Currently, weight loss remains the main management strategy for NAFLD, but the weight loss intention and methods remain poorly characterized. METHODS We analysed data about the perception of weight status, intention and methods to lose weight amongst 3,822 persons with NAFLD (United States Fatty Liver Index ≥ 30) from the National Health and Nutrition Examination Survey, 2001-2014. RESULTS Only 53.9% of people with NAFLD intended to lose weight, 91.8% with perception of overweight and 8.2% with normal weight perception. Persons with perception of overweight or overweight/obese status were four times more likely to try to lose weight (adjusted odds ratios 3.9 and 4.2, respectively, both P < 0.0001). Younger age, women, higher educational level, Hispanic and blacks (versus whites) were significant independent factors associated with weight loss intention. Notably, ≤10% attended weight loss programme. Metabolic equivalent of task hours per week was significantly higher in whites who exercised to lose weight (vs. no exercise, P = 0.003) but not in other racial/ethnic groups. Interestingly, calorie intake was similar between those who dieted versus not (2056 vs. 1970 kcal/day, P = 0.11). About 30% reported ≥ 10-lb weight loss, with 50% higher odds of success for men but there was no difference by race/ethnicity. CONCLUSION Overweight or obese perception was a key driver in weight loss activities but was inconsistent with actual weight status and varied by race/ethnicity and other sociodemographic factors. Weight loss programme is under-utilized and should take in account of weight perception training and culturally appropriate approach.

Abstract
BACKGROUND NAFLD is increasing in Asia including Japan, despite its lower obesity rate than the West. However, NAFLD can occur in lean people, but data are limited. We aimed to investigate the epidemiology of NAFLD in Japan with a focus on lean NAFLD. METHODS We searched PubMed, Cochrane Library, EMBASE, Web of Science, and the Japan Medical Abstracts Society (inception to 5/15/2019) and included 73 eligible full-text original research studies (n = 258,531). We used random-effects model for pooled estimates, Bayesian modeling for trend and forecasting, contacted authors for individual patient data and analyzed 14,887 (7752 NAFLD; 7135 non-NAFLD-8 studies) patients. RESULTS The overall NAFLD prevalence was 25.5%, higher in males (p < 0.001), varied by regions (p < 0.001), and increased over time (p = 0.015), but not by per-person income or gross prefectural productivity, which increased by 0.64% per year (1983-2012) and is forecasted to reach 39.3% in 2030 and 44.8% in 2040. The incidence of NAFLD, HCC, and overall mortality were 23.5, 7.6 and 5.9 per 1000 person-years, respectively. Individual patient-level data showed a lean NAFLD prevalence of 20.7% among the NAFLD population, with lean NAFLD persons being older and with a higher all-cause mortality rate (8.3 vs. 5.6 per 1000 person-years for non-lean NAFLD, p = 0.02). Older age, male sex, diabetes, and FIB-4 were independent predictors of mortality, but not lean NAFLD. CONCLUSION NAFLD prevalence has increased in Japan and may affect half of the population by 2040. Lean NAFLD individuals makeup 20% of the NAFLD population, were older, and had higher mortality.

Abstract
IMPORTANCE The World Health Assembly has called for the elimination of hepatitis B and C by 2030. As hepatitis B has no cure, the US strategy to eliminate hepatitis B has focused on prevention through vaccination. However, there are limited data on the trend in vaccine-associated immunity since the US implementation of universal infant hepatitis B vaccination. OBJECTIVE To compare self-reported hepatitis B vaccination coverage among children and adolescents with serologic evidence of immunity and infection in the US from 1999 to 2016. DESIGN, SETTING, AND PARTICIPANTS This population-based cross-sectional study used data from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2016. US-born persons aged 2 to 18 years without missing hepatitis B serologic test results and with reported vaccination history were included. Data were analyzed from September 2017 to June 2018. MAIN OUTCOMES AND MEASURES The proportion of participants who reported complete vaccination for hepatitis B and who had positive serologic test results indicating immunity. RESULTS Of 21 873 children and adolescents, 51.2%% were male, and the mean (SD) age was 10.6 (4.6) years. The survey reported that hepatitis B vaccination coverage increased significantly from 1999 to 2016 (from 62.6% [95% CI, 58.6%-66.4%] to 86.3% [95% CI, 82.9%-89.2%]; P < .001). Vaccine-associated immunity also increased from 1999 to 2016 among children aged 2 to 5 years (from 60.7% [95% CI, 48.8%-71.4%] to 65.2% [95% CI, 57.4%-72.3%]; P = .001) but decreased among children aged 6 to 10 years (from 64.6% [95% CI, 57.7%-70.9%] to 46.5% [95% CI, 39.1%-54.0%]; P < .001), adolescents aged 11 to 13 years (from 68.8% [95% CI, 58.1%-77.8%] to 26.2% [95% CI, 18.6%-35.5%]; P < .001), and adolescents aged 14 to 18 years (from 68.5% [95% CI, 62.9%-73.6%] to 15.6% [95% CI, 12.2%-19.8%]; P < .001). By birth year, serologic evidence of vaccine-associated immunity significantly decreased in the 1994-2003 NHANES birth cohort but not among those born between 1988 and 1993. Non-US-born children and adolescents did not show the same decreasing trend in immunity. CONCLUSIONS AND RELEVANCE In this cross-sectional study, decreasing hepatitis B immunity was observed among US-born children and adolescents in the 1994-2003 NHANES birth cohort despite increasing rates of hepatitis B vaccination coverage. These findings suggest a possible need for surveillance and a booster vaccine dose for hepatitis B as those without serologic evidence of immunity become young adults and may engage in behaviors associated with an increased risk for infection.

Abstract
INTRODUCTION Spontaneous hepatitis B surface antigen (HBsAg) seroclearance, the functional cure of hepatitis B infection, occurs rarely. Prior original studies are limited by insufficient sample size and/or follow-up, and recent meta-analyses are limited by inclusion of only study-level data and lack of adjustment for confounders to investigate HBsAg seroclearance rates in most relevant subgroups. Using a cohort with detailed individual patient data, we estimated spontaneous HBsAg seroclearance rates through patient and virologic characteristics. METHODS We analyzed 11,264 untreated patients with chronic hepatitis B with serial HBsAg data from 4 North American and 8 Asian Pacific centers, with 1,393 patients with HBsAg seroclearance (≥2 undetectable HBsAg ≥6 months apart) during 106,192 person-years. The annual seroclearance rate with detailed categorization by infection phase, further stratified by hepatitis B e antigen (HBeAg) status, sex, age, and quantitative HBsAg (qHBsAg), was performed. RESULTS The annual seroclearance rate was 1.31% (95% confidence interval: 1.25-1.38) and over 7% in immune inactive patients aged ≥55 years and with qHBsAg <100 IU/mL. The 5-, 10-, 15-, and 20-year cumulative rates were 4.74%, 10.72%, 18.80%, and 24.79%, respectively. On multivariable analysis, male (adjusted hazard ratio [aHR] = 1.66), older age (41-55 years: aHR = 1.16; >55 years: aHR = 1.21), negative HBeAg (aHR = 6.34), and genotype C (aHR = 1.82) predicted higher seroclearance rates, as did lower hepatitis B virus DNA and lower qHBsAg (P < 0.05 for all), and inactive carrier state. DISCUSSION The spontaneous annual HBsAg seroclearance rate was 1.31%, but varied from close to zero to about 5% among most chronic hepatitis B subgroups, with older, male, HBeAg-negative, and genotype C patients with lower alanine aminotransferase and hepatitis B virus DNA, and qHBsAg independently associated with higher rates (see Visual Abstract, Supplementary Digital Content 2, http://links.lww.com/CTG/A367).

Abstract
BACKGROUND Although non-alcoholic fatty liver disease (NAFLD) is commonly associated with obesity, it is increasingly being identified in non-obese individuals. We aimed to characterise the prevalence, incidence, and long-term outcomes of non-obese or lean NAFLD at a global level. METHODS For this systematic review and meta-analysis, we searched PubMed, Embase, Scopus, and the Cochrane Library from inception to May 1, 2019, for relevant original research articles without any language restrictions. The literature search and data extraction were done independently by two investigators. Primary outcomes were the prevalence of non-obese or lean people within the NAFLD group and the prevalence of non-obese or lean NAFLD in the general, non-obese, and lean populations; the incidence of NAFLD among non-obese and lean populations; and long-term outcomes of non-obese people with NAFLD. We also aimed to characterise the demographic, clinical, and histological characteristics of individuals with non-obese NAFLD. FINDINGS We identified 93 studies (n=10 576 383) from 24 countries or areas: 84 studies (n=10 530 308) were used for the prevalence analysis, five (n=9121) were used for the incidence analysis, and eight (n=36 954) were used for the outcomes analysis. Within the NAFLD population, 19·2% (95% CI 15·9-23·0) of people were lean and 40·8% (36·6-45·1) were non-obese. The prevalence of non-obese NAFLD in the general population varied from 25% or lower in some countries (eg, Malaysia and Pakistan) to higher than 50% in others (eg, Austria, Mexico, and Sweden). In the general population (comprising individuals with and without NAFLD), 12·1% (95% CI 9·3-15·6) of people had non-obese NAFLD and 5·1% (3·7-7·0) had lean NAFLD. The incidence of NAFLD in the non-obese population (without NAFLD at baseline) was 24·6 (95% CI 13·4-39·2) per 1000 person-years. Among people with non-obese or lean NALFD, 39·0% (95% CI 24·1-56·3) had non-alcoholic steatohepatitis, 29·2% (21·9-37·9) had significant fibrosis (stage ≥2), and 3·2% (1·5-5·7) had cirrhosis. Among the non-obese or lean NAFLD population, the incidence of all-cause mortality was 12·1 (95% CI 0·5-38·8) per 1000 person-years, that for liver-related mortality was 4·1 (1·9-7·1) per 1000 person-years, cardiovascular-related mortality was 4·0 (0·1-14·9) per 1000 person-years, new-onset diabetes was 12·6 (8·0-18·3) per 1000 person-years, new-onset cardiovascular disease was 18·7 (9·2-31·2) per 1000 person-years, and new-onset hypertension was 56·1 (38·5-77·0) per 1000 person-years. Most analyses were characterised by high heterogeneity. INTERPRETATION Overall, around 40% of the global NAFLD population was classified as non-obese and almost a fifth was lean. Both non-obese and lean groups had substantial long-term liver and non-liver comorbidities. These findings suggest that obesity should not be the sole criterion for NAFLD screening. Moreover, clinical trials of treatments for NAFLD should include participants across all body-mass index ranges. FUNDING None.

Abstract
BACKGROUND & AIMS The effect of hepatocellular carcinoma (HCC) on the response to interferon-free direct-acting antiviral (DAA) therapy in patients with chronic hepatitis C (CHC) infection remains unclear. Using a systematic review and meta-analysis approach, we aimed to investigate the effect of DAA therapy on sustained virologic response (SVR) among patients with CHC and either active, inactive or no HCC. METHODS PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials were searched from 1/1/2013 to 9/24/2018. The pooled SVR rates were computed using DerSimonian-Laird random-effects models. RESULTS We included 49 studies from 15 countries, comprised of 3,341 patients with HCC and 35,701 without HCC. Overall, the pooled SVR was lower in patients with HCC than in those without HCC (89.6%, 95% CI 86.8-92.1%, I2 = 79.1% vs. 93.3%, 95% CI 91.9-94.7%, I2 = 95.0%, p = 0.0012), translating to a 4.8% (95% CI 0.2-7.4%) SVR reduction by meta-regression analysis. The largest SVR reduction (18.8%) occurred in patients with active/residual HCC vs. inactive/ablated HCC (SVR 73.1% vs. 92.6%, p = 0.002). Meanwhile, patients with HCC who received a prior liver transplant had higher SVR rates than those who did not (p <0.001). Regarding specific DAA regimens, patients with HCC treated with ledipasvir/sofosbuvir had lower SVR rates than patients without HCC (92.6%, n = 884 vs. 97.8%, n = 13,141, p = 0.026), but heterogeneity was high (I2 = 84.7%, p <0.001). The SVR rate was similar in patients with/without HCC who were treated with ombitasvir/paritaprevir/ritonavir ± dasabuvir (n = 101) (97.2% vs. 94.8%, p = 0.79), or daclatasvir/asunaprevir (91.7% vs. 89.8%, p = 0.66). CONCLUSION Overall, SVR rates were lower in patients with HCC, especially with active HCC, compared to those without HCC, though heterogeneity was high. Continued efforts are needed to aggressively screen, diagnose, and treat HCC to ensure higher CHC cure rates. LAY SUMMARY There are now medications (direct-acting antivirals or "DAAs") that can "cure" hepatitis C virus, but patients with hepatitis C and liver cancer may be less likely to achieve cure than those without liver cancer. However, patients with liver cancer are also more likely to have advanced liver disease and risk factors that can decrease cure rates, so better controlled studies are needed to confirm these findings.

Abstract
BACKGROUND/AIMS A number of clinical trials reported varying effects of cholesterol lowering agents in nonalcoholic fatty liver disease (NAFLD) patients. We, therefore, assessed the changes in hepatic steatosis and NAFLD activity score (NAS) after treatment with cholesterol lowering agents in NAFLD patients by metaanalysis. METHODS The Cochrane Library, the MEDLINE, and the Embase databases were searched until May 2015, without any language restrictions, for randomized controlled trials (RCTs) and nonrandomized studies (NRSs). Additional references were obtained from review of bibliography of relevant articles. The quality of evidence was assessed using the grading of recommendations assessment, development and evaluation guidelines. RESULTS Three RCTs (n = 98) and two NRSs (n = 101) met our study inclusion criteria (adult, NAFLD, liver biopsy). Liver biopsy was performed in all five studies, but only the three studies reported NAS. Ezetimibe significantly decreased NAS (standardized mean difference [SMD], -0.30; 95% confidence interval [CI], -0.57 to -0.03) but not hepatic steatosis in RCT (SMD, -0.1; 95% CI, -0.53 to 0.32), while the effect was significant for both NAS and intrahepatic content in NRSs (SMD, -3.0; 95% CI, -6.9 to 0.91). CONCLUSION Ezetimibe decreased NAS without improving hepatic steatosis.

Abstract
BACKGROUND Genotype 3 (GT3) is a common chronic hepatitis C (CHC) genotype in Asia. Direct-acting antiviral (DAA) regimens have high cure rates, but real-world results are limited for Asia. AIM To determine the real-world effectiveness of DAAs for patients with CHC GT3 in Asia. METHODS A systematic search was performed in PubMed (including MEDLINE), Embase, and selected international meeting abstract repositories. Eligible studies were postmarketing observational studies from Asia with the primary outcome of sustained virological response 12 weeks after completion of treatment (SVR12). RESULTS A total of 15 studies with 4230 patients yielded a pooled SVR12 of 92.7%. High heterogeneity (I2=93.2%, P<0.0001) was noted. In subgroup analyses, patients with cirrhosis had 10.9% lower SVR12 than non-cirrhotic patients (88.6% vs 98.9%; P<0.0001) and contributed 69.5% of the heterogeneity. Prior treatment failure did not reduce the pooled SVR12 (treatment-naïve: 94.6%, 95% CI 91.3% to 96.7% vs treatment-experienced: 94.0%, 95% CI 77.5% to 98.6%; P=0.89). Twenty-four weeks of sofosbuvir+ribavirin dual therapy was the most commonly used regimen which led to similar SVR12 (OR=1.1, P=0.73) but lower adverse event rate than 12 weeks of sofosbuvir+ribavirin+pegylated interferon triple therapy. CONCLUSION Sofosbuvir+ribavirin for 24 weeks is the most widely used and generally well-tolerated DAA therapy in Asia. However, its effectiveness is not optimal in GT3 patients with cirrhosis.

Abstract
Background Sofosbuvir plus ribavirin (SOF+RBV) for 12 weeks is the standard treatment for chronic hepatitis C (CHC) genotype 2 (GT2) in most of Asia despite availability of new CHC medications. SOF-RBV real-world effectiveness has only been reported in small and/or single-centre studies. Our goal was to determine the real-world effectiveness of 12-week SOF+RBV therapy for CHC GT2 in Asia. Methods A systematic search on PubMed and Embase was conducted through 30 June 2017. We identified full articles and conference proceedings of at least 10 adult patients with CHC GT2 treated with SOF+RBV for 12 weeks under real-world setting in Asia. Results A total of 2208 patients from 13 studies were included. The pooled sustained virological response 12 weeks after the end of treatment (SVR12) was 95.8% (95% CI 94.6% to 96.9%) with non-significant heterogeneity (I2=34.4%). Anaemia (27.9%) was the most common adverse event (AE), with serious AEs in 2.0% and only 0.7% discontinued therapy prematurely. In subgroup analyses, patients with cirrhosis had 8.7% lower SVR12 than non-cirrhotic patients (P<0.0001), and treatment-experienced patients had 7.2% lower SVR12 than treatment-naïve patients (P=0.0002). Cirrhotic treatment-experienced patients had the lowest SVR12 at 84.5%. There were no significant differences in pooled SVR12 among patient subgroups: RBV dose reduction versus no dose reduction (P=0.30); hepatocellular carcinoma (HCC) versus no HCC (P=0.10); GT 2a versus 2b (P=0.86); and <65 vs ≥65 years of age (P=0.20). Conclusions SOF+RBV for 12 weeks was safe and effective for patients with CHC GT2 in Asia, although those with cirrhosis and prior treatment failure had a lower pooled SVR12 rate. Trial registration number CRD42017067928.

Abstract
BACKGROUND Direct-acting antiviral (DAA) regimens have shown high efficacy and tolerability for patients with HCV genotype 1/1b (GT1/1b) in clinical trials. However, robust real-world evidence of interferon (IFN)-free DAA treatment for HCV GT1-infected patients in Asia is still lacking. AIM To systematically review and meta-analyse the effectiveness and tolerability of IFN-free DAA therapy for HCV GT1 infection in Asia. METHODS We included studies that enrolled adult patients with HCV GT1 infection in routine clinical practice in Asia, using IFN-free DAA regimens, and reported sustained virological response (SVR) after 12/24 weeks end-of-treatment by 31 May 2017. The pooled SVR rates were computed with a random-effects model. Subgroup analysis and meta-regression as previously registered in PROSPERO were performed to determine how pre-planned variables might have affected the pooled estimates. RESULTS We included 41 studies from eight countries and regions, comprising of 8574 individuals. The pooled SVR rates for GT1 were 89.9% (95% CI 88.6-91.1, I2 = 55.1%) with daclatasvir/asunaprevir (DCV/ASV) and 98.1% (95% CI 97.0-99.0, I2 = 41.0%) with ledipasvir/sofosbuvir ± ribavirin (LDV/SOF ± RBV). Baseline cirrhosis but not prior treatment history and age, attenuated the effectiveness of both regimens. Baseline resistance associated substitutions (RASs) severely attenuated SVR of DCV/ASV (65.4% vs 94.3%, P < 0.001) and only minimally with LDV/SOF ± RBV (94.5% vs 99.2%, P = 0.003). Patients with renal dysfunction treated with DCV/ASV showed a higher SVR rate (93.9% vs 89.8%, P = 0.046). Patients with hepatocellular carcinoma (HCC) LDV/SOF ± RBV achieved a lower SVR than those without HCC (94.1% vs 98.7%, P = 0.001). CONCLUSION All oral DAA treatment of HCV GT1 resulted in high cure rates in Asian patients in routine clinical practice setting including elderly patients and those with end-stage renal disease.

Abstract
In the United States, non-alcoholic fatty liver disease (NAFLD) is the most common liver disease and associated with higher mortality according to data from earlier National Health and Nutrition Examination Survey (NHANES) 1988–1994. Our goal was to determine the NAFLD prevalence in the recent 1999–2012 NHANES, risk factors for advanced fibrosis (stage 3–4) and mortality. NAFLD was defined as having a United States Fatty Liver Index (USFLI) > 30 in the absence of heavy alcohol use and other known liver diseases. The probability of low/high risk of having advanced fibrosis was determined by the NAFLD Fibrosis Score (NFS). In total, 6000 persons were included; of which, 30.0% had NAFLD and 10.3% of these had advanced fibrosis. Five and eight-year overall mortality in NAFLD subjects with advanced fibrosis was significantly higher than subjects without NAFLD ((18% and 35% vs. 2.6% and 5.5%, respectively) but not NAFLD subjects without advanced fibrosis (1.1% and 2.8%, respectively). NAFLD with advanced fibrosis (but not those without) is an independent predictor for mortality on multivariate analysis (HR = 3.13, 95% CI 1.93–5.08, p<0.001). In conclusion, in this most recent NHANES, NAFLD prevalence remains at 30% with 10.3% of these having advanced fibrosis. NAFLD per se was not a risk factor for increased mortality, but NAFLD with advanced fibrosis was. Mexican American ethnicity was a significant risk factor for NAFLD but not for advanced fibrosis or increased mortality.

Abstract
OBJECTIVE This study adapted an existing computer-delivered brief alcohol intervention (cBAI) for use in Veterans with the hepatitis C virus (HCV) and examined its acceptability and feasibility in this patient population. METHODS A four-stage model consisting of initial pilot testing, qualitative interviews with key stakeholders, development of a beta version of the cBAI, and usability testing was used to achieve the study objectives. RESULTS In-depth interviews gathered feedback for modifying the cBAI, including adding HCV-related content such as the health effects of alcohol on liver functioning, immune system functioning, and management of HCV, a preference for concepts to be displayed through "newer looking" graphics, and limiting the use of text to convey key concepts. Results from usability testing indicated that the modified cBAI was acceptable and feasible for use in this patient population. CONCLUSIONS The development model used in this study is effective for gathering actionable feedback that can inform the development of a cBAI and can result in the development of an acceptable and feasible intervention for use in this population. Findings also have implications for developing computer-delivered interventions targeting behavior change more broadly.

Abstract
BACKGROUND & AIMS There are limited data on the early effectiveness of direct-acting antiviral (DAA) therapies for patients with hepatitis C virus (HCV) infection in routine medical practice. We aimed to evaluate real-world experience with DAA-based regimens. METHODS By using the Veterans Affairs' Clinical Case Registry, we conducted a prospective observational intent-to-treat analysis of veterans infected with HCV genotype 1 who began treatment with pegylated interferon, ribavirin, and boceprevir (BOC, n = 661) or telaprevir (TVR, n = 198) before January 2012. We determined rates of virologic response at treatment weeks 4, 8, 12, and 24; futility; early discontinuation; and adverse hematologic events. RESULTS About one third of patients discontinued treatment by week 24 (30% BOC, 34% TVR). A higher percentage of treatment-naive, noncirrhotic patients receiving BOC had undetectable levels of virus at week 24 than patients receiving TVR (74% vs 60%; P = .03). There were no significant differences in rates of early response within subgroups of cirrhotic patients, prior relapsers, prior partial responders, or prior null responders. By week 24, treatment was determined to be futile for 14% of patients receiving BOC and 17% of those receiving TVR. No differences were observed in overall rates of anemia (50% BOC, 49% TVR) or thrombocytopenia (16% BOC, 18% TVR); higher rates of neutropenia were observed in BOC-treated patients (34% BOC, 21% TVR; P = .008). CONCLUSIONS HCV-infected veterans treated in routine medical practice with DAA-based regimens (BOC or TVR) had rates of early response comparable with those reported in clinical trials. However, they had higher rates of futility and early discontinuation than clinical trial participants. Further studies are needed to determine rates of sustained viral response.

Abstract
Most individuals infected with the hepatitis C have not received antiviral treatment, with mental health and substance abuse problems being the primary barrier. Interventions have been developed to address these barriers among HCV patients considered "high-risk" for antiviral treatment. We present the design and methods of a prospective, randomized controlled multisite trial being conducted in the Veterans Affairs Healthcare System. The study employed a parallel design and the three study sites randomized a total of 364 VA patients with HCV to either Integrated Care (IC) or Usual Care (UC). The IC intervention consisted of a mental health provider (MHP) performing a) brief interventions to address risk factors; b) collaborative consultation with the HCV treatment clinicians; and c) case management prior to and during antiviral treatment. Clinical outcomes were abstracted from patient medical records and self-report questionnaires were completed at baseline, 4-months, 16-months, and 22-months after enrollment. The primary outcome of the study was sustained viral response (SVR). Secondary clinical outcomes were HCV treatment initiation and completion rates. Other secondary outcomes included substance use, depression, PTSD symptoms, quality of life, healthcare satisfaction, and healthcare utilization. The Integrated Care intervention has the potential to transform HCV antiviral treatment by increasing the number of HCV-infected individuals that can be successfully treated.

Abstract
Many orthopedic surgeons train or are employed at the Department of Veterans Affairs (VA) hospitals. We sought to determine the prevalence of hepatitis C antibody-positive and hepatitis C-viremic patients in the VA population undergoing total joint arthroplasty. In this prospective cohort study, 381 of 408 patients undergoing primary total joint arthroplasty for 22 consecutive months were tested for hepatitis C virus (HCV) infection preoperatively. Thirty-two (8.4%) of 381 patients were positive for hepatitis C virus antibody. Seventeen were actually viremic at the time of total joint arthroplasty (4.5%). The prevalence of detectable hepatitis C antibody in VA patients undergoing total joint arthroplasty is about 6 times the general population (1.3%). Surgeons practicing on populations with a high prevalence of hepatitis C such as this should do all they can to minimize the risk of sharps injury.

Abstract
OBJECTIVES Determine the relative impact of chronic hepatitis C (CHC) and co-morbid illnesses on health-related quality of life (HRQoL) in 3023 randomly selected veterans with known hepatitis C virus antibody (anti-HCV) status who previously completed a veteran-specific HRQoL questionnaire (SF-36V). METHODS Multiple regression analyses were performed to measure the relative contribution of anti-HCV status, four demographic variables, and ten common medical and six psychiatric co-morbidities to HRQoL between 303 anti-HCV(+) and 2720 anti-HCV(-) patients. RESULTS Anti-HCV(+) veterans were younger, reported a lower HRQoL on seven of eight 36-Item Short Form Health Survey for Veterans (SF-36V) subscales (P < or = 0.001) and the mental component summary (MCS) scale (P < 0.001). The ten medical and six psychiatric co-morbidities had variable impact on predicting lower HRQoL in both groups. After adjusting for demographic variables and co-morbid illnesses, we found that anti-HCV(+) patients reported a significantly lower MCS score (P < 0.001) and a trend toward a lower physical component summary (PCS) score (P < 0.07) compared to anti-HCV(-) veterans. Among the anti-HCV(+) veterans, co-morbid medical illnesses contributed to impaired PCS but not to MCS. CONCLUSIONS Veterans with CHC were younger than HCV(-) veterans and hence less likely to have other co-morbid medical illnesses. Medical co-morbidities seen in those veterans with CHC contribute to impaired PCS but not MCS. Anti-HCV(+) status negatively affects HRQoL, particularly MCS, independently of medical and psychiatric co-morbidities.

Abstract
Immunization is the most effective way to prevent transmission of HBV and, hence, the development of acute or chronic hepatitis B. The national strategy to eliminate transmission of the virus in the United States includes vaccination of all newborn infants, children, adolescents, and high-risk adults. Postexposure prophylaxis is also advocated, depending on the vaccination and anti-HBs status of the exposed person. Seroprotection after vaccination, defined as anti-HBs > or = 10 mIU/mL, is achieved in over 95% of all vaccinees. The hepatitis B vaccines are very well tolerated with usually minimal adverse effects. Predictors of non-response include increasing age, male gender, obesity, tobacco smoking, and immunocompromising chronic dis-ease. For those who remain nonresponders after the second series of vaccination, adjuvants such as GM-CSF may be considered, but their results are variable.

Abstract
UNLABELLED Clinical factors such as age, gender, alcohol use, and age-at-infection influence the progression to cirrhosis but cannot accurately predict the risk of developing cirrhosis in patients with chronic hepatitis C (CHC). The aim of this study was to develop a predictive signature for cirrhosis in Caucasian patients. All patients had well-characterized liver histology and clinical factors; DNA was extracted from whole blood for genotyping. We validated all significant markers from a genome scan in the training cohort, and selected 361 markers for the signature building. Using a "machine learning" approach, a signature consisting of markers most predictive for cirrhosis risk in Caucasian patients was developed in the training set (N = 420). The Cirrhosis Risk Score (CRS) was calculated to estimate the risk of developing cirrhosis for each patient. The CRS performance was then tested in an independently enrolled validation cohort of 154 Caucasian patients. A CRS signature consisting of 7 markers was developed for Caucasian patients. The area-under-the-ROC curves (AUC) of the CRS was 0.75 in the training cohort. In the validation cohort, AUC was only 0.53 for clinical factors, increased to 0.73 for CRS, and 0.76 when CRS and clinical factors were combined. A low CRS cutoff of <0.50 to identify low-risk patients would misclassify only 10.3% of high-risk patients, while a high cutoff of >0.70 to identify high-risk patients would misclassify 22.3% of low-risk patients. CONCLUSION CRS is a better predictor than clinical factors in differentiating high-risk versus low-risk for cirrhosis in Caucasian CHC patients. Prospective studies should be conducted to further validate these findings.

Abstract
Studies have indicated a high prevalence of hepatic steatosis in patients with chronic hepatitis C (CHC). To address the impact of steatosis on the clinical course of CHC and treatment response requires large multicenter studies. The present study analyzed hepatitis C virus (HCV)-infected veterans enrolled in a U.S. Veteran Administration multicenter study of the epidemiology and response to interferon alpha-2b and ribavirin treatment. Of the 357 patients, 97.1% were males, with a mean age of 48.7+/-6.4 years, and 184 (51.5%) had hepatic steatosis. The mean body mass index (BMI) was 29.3+/-5.2 kg/m(2), including 37.1% who were obese (BMI, > or =30 kg/m(2)). Stage III-IV fibrosis was present in 111 of 334 (33.3%) of the patients. After adjusting for age, race, and history of alcohol use in the past 12 months, only stage III-IV fibrosis was independently and significantly associated with hepatic steatosis (P=0.03). There was a trend of association between obesity and steatosis independent of the other factors. Only HCV genotype was independently associated with a sustained virological response (SVR) to interferon alpha-2b and ribavirin treatment after adjusting for age, alcohol use, steatosis, BMI, stage III-IV fibrosis, serum AFP, and HCV load. In conclusion, analyses of our multicenter trial data demonstrated that the prevalence of hepatic steatosis is 51.5% in HCV-infected U.S. veterans. We found that steatosis is independently associated with stage III-IV fibrosis. However, only HCV genotype, and not steatosis, obesity, or stage III-IV fibrosis, was associated with SVR to interferon alpha-2b and ribavirin treatment.

Abstract
GOALS To determine the relative impact of chronic hepatitis C (CHC) and comorbid psychiatric illness on the health-related quality of life (HRQoL). BACKGROUND Psychiatric conditions are more common among patients with CHC but their relative influence on HRQoL is not well understood. STUDY We identified 864 veterans who had previously completed a veteran-specific HRQoL questionnaire (SF-36V) as part of the 1999 VA Large Health Survey with known HCV antibody (anti-HCV) status before the survey. For 201 anti-HCV(+) and 663 anti-HCV(-) patients, we compared the HRQoL status and the prevalence of 6 major psychiatric diagnoses. We conducted multiple regression analyses to measure the effect of anti-HCV status and psychiatric comorbidity. RESULTS Compared with the anti-HCV(-) group, anti-HCV(+) veterans were more likely to have alcohol dependence (P<0.001), depression (P=0.01), or posttraumatic stress disorder (PTSD) (P<0.004). The anti-HCV(+) group also reported lower HRQoL on 4 of the 8 SF-36V subscales (P<0.01) and the mental component summary scale (P<0.001). Even after adjusting for demographic variables and comorbid psychiatric illness, anti-HCV(+) patients reported a significantly lower mental component summary score (P<0.01) than did anti-HCV(-) patients. Multiple regression analysis found that depression and PTSD predicted lower HRQoL scores for all 8 HRQoL subscales (P<0.01) and both the physical (P<0.001) and mental component (P<0.03) summary scales independent of anti-HCV status. CONCLUSIONS The HRQoL is significantly impaired in veterans with CHC, particularly the mental health components of HRQoL. In contrast, comorbid depression and PTSD are associated with both lower physical and mental components of HRQol, independent of CHC.

Abstract
BACKGROUND AND AIMS Statins are considered contraindicated in patients with chronic liver disease. Our objective was to determine the risk of developing hepatotoxicity from statin therapy in hyperlipidemic patients with hepatitis C. METHODS Changes in liver biochemistry values within 12 months compared with baseline were determined in 3 cohorts matched for age, sex, and body mass index: (I) 166 anti-hepatitis C virus (HCV)-positive hyperlipidemic veterans who were initiated on statin therapy; (II) 332 anti-HCV-positive veterans who had not received statin therapy; and (III) 332 anti-HCV-negative hyperlipidemic veterans who were initiated on statin therapy. An increase in liver biochemistry values was defined as mild-moderate or severe as proposed in a previous study on statin hepatotoxicity in a non-hepatitis C population. RESULTS In patients with hepatitis C, statin therapy (cohort I) was associated with a higher incidence of mild-moderate liver biochemistry value increases compared with those not on statin therapy (cohort II) (22.9% vs 13.3%, respectively, P = .009), but a lower incidence of severe increases (1.2% vs 6.6%, respectively, P = .015). Among patients started on statin therapy (cohorts I and III), the incidence of mild-moderate liver biochemistry value increases (22.9% vs 16.3%, respectively, P = .094), severe increases (1.2% vs 1%, respectively, P = .874), or discontinuation of statin therapy as a result of hepatotoxicity (21.6% vs 9.2%, respectively, P = .147) were similar in hepatitis C-positive and hepatitis C-negative patients. CONCLUSIONS Statin therapy was not associated with a higher risk of severe hepatotoxicity in patients with chronic hepatitis C and appeared safe.

Abstract
We sought to determine the outcomes of a screening program for hepatitis C virus (HCV) infection. Of 536 veterans initially screened between July 2000 and June 2001 for risk factors and then tested positive for antibody for HCV, only 260 (48.5%) kept their initial appointments for further evaluation; 51 were not viremic and only 19 (9.1%) were treatment eligible. Of the 276 who did not keep their initial appointments, 92 were subsequently evaluated over the next 2 years and 23 (25%) were treatment eligible, along with another 15 from the first group. Thus, with appropriate intervention and long-term follow-up, there were 57 treatment candidates. In conclusion, most veterans who tested positive either failed to keep their appointment or were ineligible for treatment when first evaluated. Over the following 2 years, some were lost to follow-up, many continued to have contraindication(s) to antiviral therapy, and relatively few were treatment candidates.

Abstract
BACKGROUND & AIMS Previously identified clinical risk factors such as sex, alcohol consumption, and age at infection do not accurately predict which patients with chronic hepatitis C (CHC) will develop advanced fibrosis (bridging fibrosis and cirrhosis). The aim of this study was to identify genetic polymorphisms that can predict the risk of advanced fibrosis in patients with CHC. METHODS A total of 916 subjects with CHC was enrolled from 2 centers. A gene-centric disease association study of 24,832 putative functional, single nucleotide polymorphisms (SNPs) was performed. Of the 1609 SNPs that were significantly associated (P </= .05) with advanced fibrosis in the discovery cohort (University of California San Francisco [UCSF], N = 433), the first batch of 100 SNPs were selected for validation in the replication cohort (Virginia Commonwealth University [VCU], N = 483). RESULTS A missense SNP in the DEAD box polypeptide 5 (DDX5) gene was significantly associated with an increased risk of advanced fibrosis in both the UCSF and the VCU cohorts (OR, 1.8 and 2.2, respectively). Two diplotype groups, carrying the haplotypes composed of the DDX5 SNP and 2 neighboring POLG2 SNPs were also significantly associated with an increased risk of advanced fibrosis and had comparable or better risk estimates. In addition, a missense SNP in the carnitine palmitoyltransferase 1A (CPT1A) gene was associated with a decreased risk of advanced fibrosis in both the UCSF and the VCU cohorts (OR, 0.3 and 0.6, respectively). CONCLUSIONS Subjects with CHC carrying DDX5 minor allele or DDX5-POLG2 haplotypes are at an increased risk of developing advanced fibrosis, whereas those carrying the CPT1A minor allele are at a decreased risk.

Abstract
In previous hepatitis C virus (HCV) treatment studies, Black patients not only had a lower sustained viral response (SVR) rate to interferon and ribavirin (RBV) than non-Black patients but also a higher frequency of HCV genotype 1 (GT-1) infection. The aim of this community-based study was to determine whether Black patients have a lower SVR rate independent of genotype. We prospectively enrolled 785 patients (24.8% Black, 71.5% White, 3.7% others) who received interferon alpha-2b 3 MU three times weekly + RBV 1000-1200 mg/day for 24 weeks (GT-2/3) or 48 weeks (GT-1). Black patients were more commonly infected with GT-1 (86.8%vs 64.8%, P < 0.001) and less frequently had an SVR compared with non-Black patients (8.4%vs 21.6%, P < 0.001). Within GT-1, Black patients had a lower SVR rate than non-Black patients (6.1%vs 14.1%, P = 0.004) but not within GT-2/3 (50.0%vs 36.5%, P = 0.47). Black patients had lower baseline haemoglobin levels (14.8 vs 15.3 g/dL, P < 0.001) and neutrophil counts (2900 vs 4100/mm(3), P < 0.001) and required more frequent dose reductions of RBV (29.8%vs 18.5%, P < 0.001) and interferon (4.7%vs 1.6%, P = 0.012). However, dose reductions were not associated with lower SVR rates while early treatment discontinuations were (2.9%vs 25.7%, P < 0.001). Independent predictors of SVR were GT-1 [odds ratio (OR) 0.33; 95% confidence interval (CI) 0.20-0.55; P < 0.001], Black race (OR 0.45; 95% CI 0.22-0.93; P = 0.030), and advanced fibrosis, stages 3 + 4 (OR 0.53; 95% CI 0.31-0.92; P = 0.023). In conclusion, Black patients infected with HCV GT-1 (but not GT-2/3) have a lower SVR rate than non-Black patients. This is not explained by their lower baseline haemoglobin levels and neutrophil counts that lead to higher rates of ribavirin and interferon dose reductions.

Abstract
OBJECTIVES The natural history of chronic hepatitis C and treatment response are different between blacks and Caucasians, but little comparable data is available about Latinos. METHODS A cross-sectional secondary analysis to investigate differences between 421 anti-HCV-positive, treatment-naïve, HCV-viremic Latinos and 2,510 Caucasians in 24 VA medical centers enrolled in a prospective study. RESULTS Latinos were infected at a younger age and were less likely to have blood contact during combat, surgery, and needle stick injury, but were more frequently HIV coinfected (20.4%vs 3.9%, p < 0.0001) and prior HAV infection (39.9%vs 26.4%, p= 0.0001). Latinos were more likely to be treatment candidates, but less likely to actually initiate treatment. Liver histology (123 Latinos, 743 Caucasians) showed no difference in fibrosis or fibrosis rate, but steatosis (54.7%vs 43.2%, p= 0.038) was more common in Latinos. Eighty-eight Latinos and 481 Caucasians were subsequently treated with interferon-ribavirin: body mass index (BMI), duration of infection, baseline tests, liver histology and genotype distribution were similar. Compared with Caucasians, Latinos discontinued treatment prematurely more often (39.8%vs 28.9%, p= 0.043) and tended to have lower sustained virological response (SVR) rates (14.8%vs 22.5%, p= 0.10). Multivariate analysis found Latino race and history of recent alcohol use to be associated with early treatment discontinuation, whereas genotype and viral load but not ethnicity to be associated with SVR. CONCLUSIONS Latinos were infected younger, more frequently HIV coinfected, more likely to meet criteria for antiviral therapy yet less likely to initiate treatment and had a trend toward lower SVR rates than Caucasians, but not in severity of liver disease. Latino ethnicity was associated with early discontinuation but not as an independent predictor of SVR.

Abstract
SUMMARY Treatment of chronic hepatitis C (CHC) continues to be an important and growing challenge. As the response rate to FDA-approved treatment improved over the past decade, we are facing increasing number of difficult-to-treat patients such as those who have failed prior anti-viral therapy. The role of amantadine in the treatment of CHC remains unclear. Studies thus far have produced conflicting results, and type II error could not be excluded. This review summarized results published in the literature from 1997 to 2003, and reviewed the existing questions and controversies regarding the use of amantadine. Current literature suggests that amantadine is ineffective as monotherapy. Amantadine increased the sustained virologic response of certain treatment naïve patients when used in combination with interferon, and may be effective as an adjunct to interferon-based combination therapy in some patients who have failed or relapsed on prior therapy. Factors such as small sample size, patient characteristics, and differences in treatment protocols including amantadine preparation and duration of therapy might explain the conflicting observations of various studies. Further investigations are needed to define optimal dosing and formulation of amantadine, and its appropriate role in management of CHC infection.

Abstract
Inhibition of inosine monophosphate dehydrogenase (IMPDH) is one of several proposed mechanisms of action for ribavirin (RBV), a critical component of the current treatment for chronic hepatitis C (CHC). This study was a double-blind, placebo-controlled dose-escalation study of a novel, selective, orally active small molecule inhibitor of IMPDH, merimepodib (VX-497 or MMPD) in combination with standard interferon-alpha (IFN-α). Fifty-four treatment-naive patients with genotype-1 CHC were randomized to receive IFN-α 3 MIU subcutaneously three times a week, alone or in combination with 100 mg or 300 mg (every 8 h) of MMPD for 4 weeks. At the end of 4 weeks, all patients were offered 48 weeks of treatment with IFN-α/RBV. The objectives of the study were to evaluate the tolerability of the IFN-α/MMPD combination and to evaluate whether MMPD had an on-treatment effect on HCV-RNA, similar to RBV when added to IFN-α. The drug combination was generally well tolerated; one patient at the higher dose discontinued because of elevated alanine aminotransferase levels. No pharmacokinetic interactions were evident between the two drugs. Analysis of covariance that adjusted for a baseline imbalance in HCV-RNA in the intent-to-treat population did not show any significant differences between the treatment groups, or between MMPD plus IFN-α compared with IFN-α alone. However, the per-protocol primary efficacy analysis based on treatment-compliant patients demonstrated a greater reduction in mean HCV-RNA in the combination of 100 mg MMPD plus IFN-α compared with IFN-α alone (-1.78 log vs -0.86 log, P=0.037). In conclusion, the addition of a selective IMPDH inhibitor to IFN-α was well tolerated. In a low-dose range, the addition of MMPD may have the potential to add to the antiviral efficacy of IFN-α. Larger, longer duration trials incorporating pegylated IFN would be required to determine whether this combination, alone or with RBV, would increase either early or sustained virological response rates.

Abstract
STUDY OBJECTIVE To evaluate the survival of patients with advanced liver disease to determine if known exposure to general anesthesia within a 5-year period has a measurable effect on mortality. DESIGN Retrospective survival analysis of male veterans with advanced liver disease. SETTING Tertiary referral VA Medical Center and university-affiliated teaching hospital. MEASUREMENTS One hundred twenty-seven patients with a history of alcoholic cirrhosis and documented hepatitis C infection and stable platelet counts were identified and then divided into 3 groups. The 5-year survival rates in all 3 groups were compared using Kaplan-Meier survival curves. MAIN RESULTS Ninety patients had marked thrombocytopenia (<100000/mm3). Their survival rates with and without known exposure to general anesthesia were compared with those of control subjects with alcoholic cirrhosis and hepatitis C infection but with platelet counts greater than 100000/mm3. The 5-year survival rate of 57% in the group that received general anesthesia was comparable to the 58% rate observed in the group without this exposure. Both groups' rates were statistically lower than the 5-year survival rate of 77% in the group with advanced liver disease but without thrombocytopenia. CONCLUSION Comparably high mortality rates were observed in patients with advanced liver disease with or without exposure to general anesthesia. Higher survival rates were noted in patients with advanced liver disease who were not thrombocytopenic.

Several human leukocyte antigen (HLA)-peptide tetramers for the detection of hepatitis C virus (HCV)-specific CD8(+) T cells are under evaluation. METHODS Evaluation of one HLA class I-tetramer (HCVNS3-2) for the detection of HCV NS3-specific CD8(+) T cells in a series of 38 HLA-A2(+) chronically infected patients. RESULTS Almost half (42%) of the patients had detectable NS3-specific CD8(+) T cells. The frequencies of such cells ranged from 0.01% to 0.22% of total CD8(+) T cells. No significant differences in clinical features or mean viral load were detected between patients with or without tetramer + CD8(+) T cells. CONCLUSIONS The tetramer HCVNS3-2 may be very useful for the study of the HCV-specific CD8(+) immune response. Combination of this reagent with other tetramers based on other HCV peptides may help in the understanding of the immune response to the virus. However, a panel of tetramers based on several parts of the HCV polyprotein may be a mandatory requirement to explore the whole breadth of the CD8(+) T-cell response against HCV and to detect that response in the majority of patients with chronic infection.

Abstract
Immunization is the most effective way to prevent transmission of HBV and, hence, the development of acute or chronic hepatitis B. The national strategy to eliminate transmission of the virus in the United States includes vaccination of all newborn infants, children, adolescents, and high-risk adults. Postexposure prophylaxis is also advocated, depending on the vaccination and anti-HBs status of the exposed person. Seroprotection after vaccination, defined as anti-HBs > or = 10 mIU/mL, is achieved in over 95% of all vaccinees. The hepatitis B vaccines are very well tolerated with usually minimal adverse effects. Predictors of non-response include increasing age, male gender, obesity, tobacco smoking, and immunocompromising chronic disease. For those who remain nonresponders after the second series of vaccination, adjuvants such as GM-CSF may be considered, but their results are variable.

Abstract
Hepatitis C virus (HCV) variation in specific T-cell epitopes may represent a mechanism of viral persistence in chronic infection. We examined the HCV non-structural protein 3 (NS3), including the immunologically relevant epitopes HCV NS3-2 KLVALGINAV (human leukocyte antigen [HLA]-A2-restricted) and HCV NS3-1391 LIFCHSKKK (HLA-A3-restricted), in 22 HLA-A2+ patients with chronic infection. Significant amino acid variation was found in HCV NS3-2 epitope sequences when compared to the HCV-1 prototype virus. Six of the nine different HCV NS3-2 peptide variants were identified in patients with HCV NS3-2-specific CD8+ cells, detected with an HLA-A2 tetramer made with the HCV-1 prototype peptide. Phylogenetic analysis, including HCV reference sequences other than HCV-1, suggested however that most of the variations in the HCV NS3-2 epitope could be related to genetic heterogeneity between HCV reference subtypes. Variation was less common when comparing HCV NS3-2 epitope sequences from the clinical isolates to the most-closely related HCV reference subtype in each case. Some subtype-independent variations were found in epitopic residues probably important for T-cell receptor interaction. In contrast, no significant variation was found in HLA primary anchor sites, flanking regions, or in the contiguous HLA A3-restricted CD8+ T-cell epitope. Ongoing variation was not evident in two selected patients with follow-up. In conclusion, (i) the HCV NS3-2 epitope is not conserved between different HCV strains/subtypes, and (ii) an HLA-A2 tetramer loaded with the HCV-1 prototype NS3-2 peptide may still detect NS3-specific CD8+ cells in some patients with variant viruses. These data may be useful to improve T-cell assays using HCV NS3 peptides, taking into account the genetic diversity of this virus.

Abstract
UNLABELLED The impact of the hepatitis C virus (HCV) infection on the postoperative complication rate is unknown. We identified a population of surgical patients (n = 2457) for whom the HCV antibody (anti-HCV) had been measured and compared after surgical complications and mortality between those who were positive (17.9%) versus negative. The complication rates were 10% in the anti-HCV positive and 13% in the negative group (P = 0.125), whereas the mortality rates were 0.7% and 2.5%, respectively (P = 0.017). The anti-HCV positive patients were younger, had lower ASA physical status, and underwent shorter procedures. In the univariate analysis, emergent surgery and high ASA physical status but not anti-HCV positivity were associated with a more frequent complication. In the multivariate analysis, the urgency of surgery, age, ASA physical status, length of surgery, and preoperative hematocrit (but not platelet count) were associated with complications. Anti-HCV positivity was associated with an odds ratio for having a complication of 1.08 (95% confidence interval, 0.90-1.30), which was not statistically significant (P = 0.405). In conclusion, we were unable to show HCV antibody status to be an independent risk factor for postoperative complications when other co-factors were considered. IMPLICATIONS In this large study at a Veterans Administration medical center, the urgency of surgery, age, ASA physical status, length of surgery, and preoperative hematocrit were all independently associated with postoperative complications. However, hepatitis C infection was not an independent risk factor for postoperative complications.

Abstract
OBJECTIVE The aim of this study was to determine the incidence of psychiatric comorbidities among veterans with chronic hepatitis C. METHODS Depression, anxiety sensitivity, post-traumatic stress symptoms, and alcohol use were assessed using standardized questionnaires in 120 consecutive veterans with chronic hepatitis C referred to the Liver Clinic. RESULTS Using well-established scoring criteria of the questionnaires, clinically significant levels of depression (44.2%), anxiety (38.1%), post-traumatic stress disorder (20.8%), and alcohol-related problems (26.7%) were observed. The majority of patients had a clinically significant score for at least one questionnaire, whereas 37.2% had significant scores in two or more questionnaires. Positive correlations were found between post-traumatic symptoms and depressive symptoms, anxiety sensitivity, and alcohol use problems. Depressive symptoms were also correlated with anxiety. Responses to the questionnaires, in general, correlated poorly with psychiatric histories documented in the medical record. Overall, 79 (65.8%) patients had one or more possible contraindications to antiviral therapy: coexisting unstable psychiatric disorders and/or recent substance use was found in 73.4% of these patients. CONCLUSIONS Psychiatric comorbidities were very common among veterans with chronic hepatitis C and correlated poorly with diagnoses documented in the medical record. We recommend a multidisciplinary approach that includes psychological assessment using standardized questionnaires in the evaluation of these patients for antiviral therapy.
