Much of the current data on nonalcoholic fatty liver disease (NAFLD) are derived from biopsy‐based studies that may introduce ascertainment and selection bias. Selection of patients for liver biopsy has implications for clinical practice and the reported epidemiology of NAFLD. The aim of this study was to determine patient factors predictive of histologic versus empiric clinical diagnosis of NAFLD in real‐world practice. Adults from TARGET‐NASH were included in this study. Descriptive statistics are provided for the cohort and compare the characteristics of histologic NAFLD versus patients with clinically diagnosed NAFLD, followed by logistic regression and machine‐learning models to describe predictors of liver biopsy. The records of 3,474 subjects were analyzed; median age was 59 years, 59% were female, 75% were White, and median body mass index was 32 kg/m2. Using histologic and/or clinical criteria, a diagnosis of nonalcoholic steatohepatitis was made in 37%, and cirrhosis in 33%. Comorbid conditions included cardiovascular disease (19%), mental health diagnoses (49%), and osteoarthritis (10%). Predictors of a biopsy diagnosis included White race, female sex, diabetes, and elevated alanine aminotransferase (ALT). ALT increased the odds of liver biopsy by 14% per 10‐point rise. Machine‐learning analyses showed non‐White patients with ALT, The aim of this study was to determine patient factors predictive of histologic versus empiric clinical diagnosis of NAFLD in real world practice in adults enrolled in the TARGET‐NASH study. The records of 3,474 subjects were analyzed; median age was 59 years, 59% were female, 75% were white, and median BMI was 32 kg/m2. In this real‐world cohort of patients with NAFLD, two thirds of patients did not have a liver biopsy; these patients were more likely to be non‐white, older, with a normal ALT.

INTRODUCTION Entecavir (ETV) and tenofovir alafenamide (TAF) are both first-line hepatitis B virus (HBV) therapies, but ETV-to-TAF switch outcome data are limited. We aimed to assess outcomes up to 96 weeks after ETV-to-TAF switch. METHODS ETV-treated (≥12 months) chronic hepatitis B patients switched to TAF in routine practice at 15 centers (United States, Korea, Japan, and Taiwan) were included. Primary outcome was complete viral suppression (CVS) rate (HBV DNA

INTRODUCTION:It is unclear whether entecavir (ETV) and tenofovir disoproxil fumarate (TDF) differ in their effectiveness for preventing hepatocellular carcinoma (HCC) in patients with chronic hepatitis B (CHB).METHODS:This retrospective cohort study analyzed an international consortium that encompas

Antiviral therapy is recommended for pregnant women with chronic hepatitis B (CHB) and hepatitis B virus (HBV) DNA200,000 IU/mL, but there is less consensus on management of women who discontinue therapy in anticipation of pregnancy or who become pregnant while on therapy. The goal of this study was to describe flares in alanine aminotransferase (ALT) during pregnancy and postpartum in CHB women with current and/or prior treatment.This was a multicenter, retrospective study of 67 pregnancies in 56 CHB women treated before and/or during pregnancy. Main outcomes were frequency, severity, and resolution of ALT flare (≥5× upper limit of normal or ≥3× baseline, whichever was higher).During pregnancy, ALT flares (95 to 1064 U/L) were observed in 16% (7/43) of women who stopped treatment before pregnancy and 31% (4/13) of women who discontinued treatment during first trimester, many of whom had high HBV DNA levels (4.9 to 8.0 log IU/mL). No flares (0/11) were observed in women who continued treatment. Postpartum ALT flares (104 to 1584 U/L) were observed in 0% (0/15) of women who were completely untreated during pregnancy, 29% (2/7) of women who discontinued treatment in first trimester, 33% (3/9) of women who stopped treatment at delivery, and 22% (4/18) of women who continued treatment postpartum.In previously treated women with CHB, ALT flares were common during pregnancy and postpartum, especially if antiviral therapy was discontinued shortly before pregnancy, during first trimester, or at delivery. Thus, these pregnant women should be monitored closely throughout pregnancy and the early postpartum period; larger studies are needed to further characterize the natural history of HBV infection during pregnancy and postpartum.

Hepatitis C genotype 6 (HCV-GT6) is one of the most prevalent genotypes in Southeast Asia. Ledipasvir and sofosbuvir fixed-dose combination (LDV/SOF FDC) for 12 weeks has been shown to be effective for multiple HCV genotypes including treatment-naïve HCV-6. Our goal was to examine treatment outcomes in a diverse HCV-6 population.We prospectively enrolled 60 HCV-GT6 patients at four US centers. Treatment -naïve without cirrhosis patients received open-labeled LDV/SOF FDC orally once a day for 8 weeks; All cirrhotic and/or treatment-experienced patients received LDV/SOF FDC for 12 weeks. The primary outcome was sustained virological response 12 weeks after therapy (SVR12). Secondary outcomes were adverse events (AEs) and/or serious adverse events (SAEs). All patients gave written consent.Overall mean age was 58±10 and 58% were male. All patients were Asian and foreign born. The 8-week group included 20 patients (33.3%) and the 12-week included 40 patients (66.7%). There were 2 (5%) patients with decompensation, 3 with liver cancer (7.5%), and 14 with prior treatment (35%) in the 12-week group. SVR12 was 95.0% for the 8-week group (19/20) and 95.0% for the 12-week group (38/40). AEs included fatigue (5%), insomnia (3.3%), headache (1.7%), and nausea (1.7%); however, all patients completed the intended treatment duration. There were two treatment-unrelated SAEs.LDV/SOF FDC for 8 or 12 weeks was safe and effective for patients without cirrhosis or prior treatment failure as well as for patients with cirrhosis and/or prior treatment failure, respectively.

Data from the United States are lacking regarding the impact of entecavir (ETV) on the risk of hepatocellular carcinoma (HCC). Our aim is to determine whether treatment with ETV is associated with a reduced HCC risk by calculating the expected HCC incidence based on the Risk Estimation for Hepatocellular Carcinoma in Chronic Hepatitis B (REACH-B) model and comparing it with the observed HCC incidence.The incidence of HCC in US patients treated with ETV between 2005 and 2013 in a retrospective cohort was obtained. The predicted HCC incidence was calculated using the REACH-B model. The standardized incidence ratios (SIRs) were calculated as a ratio of observed over predicted HCC cases.Of 841 patients, 646 (65% male, 84% Asian, median age 47 years, 36% hepatitis B e antigen positive, 9.4% with cirrhosis) met the inclusion criteria. Over a median follow-up of 4 years, 17 (2.6%) cases of HCC were diagnosed, including 8 out of 61 (13.1%) patients with cirrhosis and 9 out of 585 (1.5%) without cirrhosis. Compared with those without HCC, the 17 patients with HCC were older at 53 years vs. 47 years and more likely to have cirrhosis at 47.1% vs. 8.4%. Among patients without cirrhosis, the observed HCC incidence was significantly lower than predicted by the fourth year (SIR, 0.37; 95% confidence interval: 0.166-0.82). A sensitivity analysis that comprised all patients, including those with cirrhosis, showed that at the maximum follow-up time of 8.2 years, a significantly lower than predicted HCC incidence was noted with an SIR of 0.56 (95% confidence interval: 0.35-0.905).Based on the REACH-B model, long-term ETV therapy was associated with a lower than predicted HCC incidence. However, the risk of HCC persisted, and careful HCC surveillance remains warranted despite the anti-viral treatment.

Given their high efficacy, entecavir (ETV) and tenofovir (TDF), are the recommended first-line therapies for chronic hepatitis B, but it is not clear whether the efficacy reported from pivotal trials is similar to the outcomes seen in routine practice.Our goal was to examine the treatment outcomes of antiviral therapy in such setting.We conducted a retrospective study of 557 consecutive treatment-naive patients who started either ETV (n=443) or TDF (n=114) at 3 US liver clinics between January 2005 and 2012. Primary study endpoint was complete viral suppression (CVS) rate (hepatitis B virus DNA40 IU/mL).The majority of patients in both ETV and TDF groups were Asians, hepatitis B e antigen (HBeAg) negative, male, and with similar pretreatment alanine aminotransferase and hepatitis B virus DNA levels. Similar proportions of patients in the ETV and TDF groups achieved CVS at 24 months: 87.7% versus 87.0%, respectively. Cumulative rates of virological breakthrough in the ETV and TDF groups were 1.0% versus 4.8% (P=0.26) and 3.7% versus 9.8% (P=0.04) at month 12 and 24, respectively; and all were associated with medication nonadherence. Cumulative rate of medication nonadherence was lower in the ETV than TDF group: 4.6% versus 7.8% at month 12 and 8.9% versus 16.9% at month 24, respectively.Patients treated with either ETV or TDF achieve a similar rate of CVS at 24 months. The primary contributor to suboptimal response was medication nonadherence. Attention to medication adherence is needed in a routine clinical setting.

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 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).

Background and aims Tenofovir (TDF)-associated renal dysfunction has been described in various studies of human immunodeficiency virus-infected patients. Our goal is to examine the incidence and magnitude of decrease in renal function in chronic hepatitis B patients treated with TDF. Methods We performed a case-cohort study of 103 patients on TDF 300 mg and 103 patients unexposed to TDF (Entecavir) at 4 centers, who were matched for age±10 years, sex, and baseline estimated glomerular filtration rate (eGFR) group. Calculation and evaluation of eGFR were performed with both the Cockcroft-Gault formula and the Modification of Diet in Renal Disease formula. Results The exposed and unexposed populations were well matched with a similar mean age (44±10 y), proportion of male patients (63.1%), and baseline eGFR groups (86.4% unimpaired). There was no significant difference in the proportion of patients reclassified to a more severe renal classification (RMSRC) or in the proportion of patients with decrease in eGFR of ≥20% in those exposed to TDF versus control. The incidence density for RMSRC was 7.4 cases per 100 patient-years in the exposed group compared with 11.5 cases per 100 patient-years in the unexposed group (95% CI, 0.31-1.34). The relative risk of exposed to unexposed was 0.64 (95% CI, 0.31-1.34). On Cox proportional hazard analysis following adjustment for sex, age, baseline diagnosis hypertension, diabetes, impaired baseline renal function, and cirrhosis, TDF was not a predictor for RMSRC or decrease in eGFR≥20%. Conclusions TDF treatment was not an independent predictor for significant deterioration of renal function. Renal function of chronic hepatitis B patients on antiviral therapy should be monitored, especially in those who are older and/or with mildly impaired renal function.

Objectives It is unclear whether patients with chronic hepatitis B with partial response to entecavir (ETV) who have achieved complete viral suppression (CVS) with ETV plus tenofovir (TDF) combination therapy maintain CVS if switched to TDF or ETV. Our goal was to examine virologic outcomes in such patients. Methods This is a retrospective cohort study of 57 ETV partial responders with chronic hepatitis B who showed CVS on ETV+TDF combination therapy, who were switched back to monotherapy with either ETV (n=16) or TDF (n=18), or continued on combination therapy (n=23). The majority of patients were Asian (91%) and male (65%), with a mean age of 41±12 years. Results The patients switched back to ETV had significantly higher rates of virologic breakthrough by 6 months after the switch compared with their TDF counterparts (88 vs. 39%, P=0.004). Patients who remained on ETV+TDF also had virologic breakthrough, due to either confirmed or suspected nonadherence. On multivariate analysis inclusive of age, sex, and hepatitis B virus DNA levels at initiation of combination therapy, ETV (compared with TDF) was found to be an independent predictor for virologic breakthrough (odds ratio 112.7, P=0.03), as well as duration of CVS of less than 12 months while on ETV+TDF (odds ratio 60.2, P=0.03). Conclusion TDF monotherapy, especially in those who have had CVS for at least 12 months on combination therapy, may be considered for some ETV partial responders who have achieved CVS with combination therapy, given the financial advantage and convenience of monotherapy.

Data from registration trials with highly selective patients have shown that hepatitis B envelope antigen (HBeAg)-positive patients with chronic hepatitis B respond well to entecavir (ETV) 0.5 mg daily, with an HBeAg seroconversion rate of 21% at 12 months. However, there are varying data on the treatment outcomes of ETV 0.5 mg daily in routine clinical settings, with seroconversion rates at 12 months ranging from 8 to 48% in studies limited to 44-90 patients from centers in Asia, Europe, and South America.In the present study, we examined long-term treatment efficacy and tolerability in 136 consecutive treatment-naive HBeAg-positive chronic hepatitis B patients treated between January 2005 and January 2011 with ETV 0.5 mg daily at community clinics and tertiary centers in the USA. The primary study end point was HBeAg seroconversion.Sixty-one percent of HBeAg-positive patients were men, mean age 39 ± 12 years, median hepatitis B virus DNA 7.48 (3.7-9.8) log10 IU/ml, median alanine aminotransferase 67 (14-1077) U/l, and median treatment duration 18 (6-60) months. At months 12, 24, and 36, complete viral suppression rates were 41, 66, and 85% and HBeAg seroconversion rates were 4.8, 20, and 30%, respectively. No patients experienced adverse events or developed genotypic resistance to ETV.In clinical settings, ETV is highly tolerable and potent at suppressing hepatitis B viremia; however, the rates of HBeAg seroconversion appear to be much lower than those reported, highlighting the importance of appropriate counseling and planning for long-term therapy.

Background The primary treatment endpoint for hepatitis B e antigen (HBeAg)-positive chronic hepatitis B is HBeAg seroconversion; however, data on the durability of response are inconsistent. Goals Our goal was to investigate the rate of recurrent viremia after HBeAg seroconversion and subsequent discontinuation of therapy. Methods We retrospectively studied 88 consecutive Asian American patients who achieved HBeAg seroconversion [loss of HBeAg and development of antibody to HBeAg (anti-HBe)] among 458 HBeAg-positive patients who received oral antiviral therapy at 3 US clinics between March 1998 and November 2010. Recurrent viremia was defined as reappearance of detectable serum hepatitis B virus DNA (>100 IU/mL) on 2 consecutive laboratory tests from previously undetectable levels. Results Antiviral medications used at the time of HBeAg seroconversion included: lamivudine (23%), adefovir (34%), entecavir (36%), tenofovir (4%), and combination therapy (3%). Antiviral therapy was continued after HBeAg seroconversion in 49 patients (group I) and discontinued in the other 39 patients after consolidation therapy [median=12 months (range, 1 to 55 mo)] (group II). No patients in group I experienced recurrent viremia, whereas 90% in group II did. Elevated alanine aminotransferase also occurred in 38% of group II patients [median peak alanine aminotransferase 249 IU/mL (range, 93 to 1070 IU/mL)]. Conclusions Despite consolidation therapy, almost all patients who discontinued therapy after achieving HBeAg seroconversion and complete viral suppression experienced recurrent viremia, and close to half also experienced biochemical flares. HBeAg seroconversion does not seem to be a durable treatment endpoint for many patients, and they should be monitored carefully for virologic relapse and biochemical flares if antiviral therapy is withdrawn.

BACKGROUND Combination therapy for chronic hepatitis B virus (HBV) infection is recommended for patients with antiviral resistance (AVR) or partial response (PR) to earlier antiviral therapy; however, data on outcomes are limited. GOALS To determine the rate of complete viral suppression (CVS) with combination therapy and to compare CVS among different indications and treatment regimens. METHODS A cohort of 109 consecutive patients with chronic hepatitis B from 3 liver clinics in Northern California was retrospectively studied. All patients started combination therapy between April 2004 and August 2009 for the following indications: AVR (n = 29), PR (n = 60), or others (n = 20). Combination treatments included lamivudine (LAM), adefovir (ADV), telbivudine (LdT), entecavir (ETV), tenofovir (TDF), and emtricitabine (FTC). CVS was defined as undetectable serum HBV DNA

Studies of hepatitis B virus (HBV)/hepatitis C virus (HCV) dual infection are limited. Most are small, conducted outside the United States, and compare dual infection with HCV monoinfection. The goal of this study was to characterize HBV/HCV dual infection in a large multiethnic, matched, case-control study of dual-infected and HBV-monoinfected patients at two United States centers. Using an International Classification of Disease Version 9 electronic query and chart review, we identified 115 HBV/HCV dual-infected patients with serial HBV DNA, HCV RNA, and alanine aminotransferase (ALT) levels. As a control, 115 HBV-monoinfected patients were chosen randomly and matched with cases by age ±10 years, sex, Asian versus non-Asian ethnicity, and study site. Both groups had similar sex, ethnic, and age distributions (68% male, 83% Asian, age 52 ± 14 years). The median follow-up times were 33 and 38 months for the dual-infected and monoinfected groups, respectively. More monoinfected patients received HBV antiviral therapy than dual-infected patients (43% versus 24%; P = 0.002). No significant difference was detected between the proportion of monoinfected versus dual-infected patients with ALT above 40 U/L at presentation or during follow-up. Dual infection patients exhibited very little HBV/HCV codominance at baseline and throughout follow-up: patients had either HBV viremia with low or absent HCV RNA or detectable HCV RNA with low or absent HBV DNA. Asian ethnicity was predictive of HBV dominance after adjusting for sex, age, and baseline ALT elevation (odds ratio 7.35; P = 0.01). Conclusion: HBV/HCV dual-infected and HBV-monoinfected patients had similar clinical characteristics. Asian ethnicity is a major independent predictor of HBV-dominant disease, and HCV dominance with undetectable HBV DNA is more common in non-Asian individuals. Larger studies are needed to further characterize the natural history of HBV/HCV dual infection in Asian and non-Asian individuals. (HEPATOLOGY 2011;)

Hepatitis C virus (HCV) genotype is an important criteria in determining duration of therapy and predictor of sustained virologic response (SVR) to pegylated interferon (PEG IFN) and ribavirin (RBV) therapy. Optimal duration of therapy for patients with HCV genotype 6 is not known. We conducted a multicenter, open-label randomized controlled trial of patients with HCV genotype 6 at five gastroenterology clinics in the western U.S. Patients were stratified by viral load and histologic stage and assigned to receive PEG IFN-α2a 180 μg subcutaneously weekly and weight-based oral RBV 800 to 1,200 mg daily for 24 or 48 weeks. Primary outcome measurement was SVR rate by intention-to-treat analysis. From February 2005 to October 2007 a total of 60 patients (age 51 ± 10 years, 47% male, log HCVRNA 6.3 ± 1.1 IU/mL) were enrolled: 27 patients to 24 weeks and 33 patients to 48 weeks of therapy. In the 24-week and 48-week groups, 96% and 97% achieved early virologic response (P = 0.90); 89% versus 94% achieved end of therapy virologic response (P = 0.48). SVR was achieved in 70% versus 79% of patients assigned to 24 weeks versus 48 weeks (P = 0.45). Rapid virologic response (RVR) was a significant predictor of SVR in the 48-week group and trending towards significance in the 24-week group: 82% and 83% of those with RVR achieved SVR versus 33% and 29% for the 24-week and 48-week groups, respectively (P = 0.07 and P = 0.02). Conclusion: There was no significant difference in SVR rates in patients with HCV genotype 6 treated with PEG IFN-α2a and RBV for 24 versus 48 weeks. (HEPATOLOGY 2010;52:1573-1580)

Previous studies have found ethnicity to be an important predictor of outcomes of treatment with peginterferon (PEG-IFN) and ribavirin (RBV) in chronic hepatitis C. Although the expected sustained virological response (SVR) rates of Hispanics and African Americans are lower than those of Caucasians, SVR rates in Asians appear to be more favorable. However, in some of these studies, hepatitis C virus (HCV) genotype was identified by INNO-LiPA assay, which can mistype the easier-to-treat HCV genotype 6 as genotype 1. Our goal was to compare SVR rates among Caucasian and Asian-American patients with genotype 1 and 2/3 infection whose HCV genotypes were accurately classified by core sequencing testing.A cohort of 269 consecutive treatment-naive HCV-infected patients with genotype 1 or 2/3 (157 Caucasians and 112 Asians) treated with PEG-IFN+RBV from January 2001 to November 2007 at four community-based gastroenterology clinics in Northern California were studied. The analysis of data was by intention-to-treat.The SVR rates for patients with genotype 1 were 45% for Caucasians and 52% for Asians (P=0.37). The SVR rates for patients with genotype 2/3 infection was 77% for Asians and 74% for Caucasians (P=0.7). On multivariate logistic regression analyses adjusting for age, alanine aminotransferase (ALT), baseline viral load, HCV genotype, and treatment adherence, we did not find Asian ethnicity to predict SVR. On a separate analysis, we found that Asians who had HCV genotype 1 or 1b by the less accurate INNO-LiPA assay had significantly higher SVR rates than Caucasians with genotype 1 (64% vs. 45%, respectively, P=0.03).SVR rates were similar in Asian Americans and Caucasians infected with HCV genotype 1 or 2/3 when HCV genotype classification was accurately determined.

At present there is no clear consensus on how patients with chronic hepatitis B (CHB), high serum hepatitis B virus (HBV) DNA, and normal alanine aminotransferase (NLALT) levels should be managed. This study hypothesizes that a significant proportion of such patients may have histological disease.We carried out a retrospective study of 101 consecutive treatment-naive patients with CHB who underwent liver biopsies at a community gastroenterology clinic and had high HBV DNA and NLALT (or = 40 U/l) levels at the time of biopsy. All patients were Asians. ALT levels were observed for a period of time before liver biopsy and were used to classify patients into two groups, namely those with only NLALT levels and those with fluctuating ALT (FLALT) levels. All patients had at least two ALT measurements during this period of time. Significant histology was defined as stageor = 2 fibrosis or stage 1 fibrosis plus gradeor = 2 inflammation using the Batts-Ludwig scoring system.In patients with NLALT levels, the proportions of those with significant histology were 0, 22, and 45% for ageor = 35, 36-50, and50 years, respectively (n=11, n=27, n=19; P=0.033). In patients who had FLALT levels, the corresponding proportions were 22, 42, and 69% (n=9, n=22, n=13; P=0.091). After adjustments for gender, hepatitis B e antigen (HBeAg) status, and mean pre-biopsy HBV DNA levels, significant predictors of histological disease were older age (odds ratio (OR)=6.2 for age 36-50 years and OR=17.6 for age50 years compared with ageor = 35 years, P=0.041 and P=0.003, respectively) and FLALT levels (OR=3.6, P=0.008). Sub-analysis of patients with NLALT levels using lower cutoffs (30 U/l for men and 19 U/l for women) showed similar trends.Patients with CHB, high HBV DNA, and NLALT levels and aged more than 35 years or those with FLALT levels may have significant histological disease (22-70%).

OBJECTIVES: To determine the proportion of Barrett's esophagus (BE) in Asians versus non-Asians and the predictors of BE in patients with upper gastrointestinal (GI) symptoms. METHODS: We performed a cross-sectional study to determine the proportion of BE from all consecutive patients who underwent esophagogastroduodenoscopy (EGD) for various indications at an outpatient, community-based gastroenterology practice in northern California from February 2000 to September 2006. BE was defined as endoscopically recognized presence of salmon-pink mucosa in the distal esophagus and intestinal metaplasia on biopsy. We also performed a nested case-control study to determine potential predictors of BE. RESULTS: In total, 5,293 patients were reviewed. BE was more common in non-Asians (31/1464, 2.1%) than Asians (29/3829, 0.76%) (P < 0.001). In multivariate analysis controlling for increasing age, male gender, ethnicity, smoking, and alcohol, the strongest predictor of the presence of BE was non-Asian ethnicity (odds ratio [OR] 3.55, 95% confidence interval [Cl] 1.85-6.85), followed by male gender (OR 2.68, 95% Cl 1.32-5.45). CONCLUSION: BE is uncommon in Asian Americans; non-Asian ethnicity and male gender are significant independent predictors of BE.

For chronic hepatitis B (CHB), alanine aminotransferase (ALT) ≥2 × upper limit of normal (ULN) is often used as a major criteria to initiate treatment in absence of cirrhosis, though patients with lower ALT may not be free from future risk of hepatocellular carcinoma (HCC). We aimed to examine the effect of antiviral therapy on HCC incidence based on ALT levels. We performed a retrospective study on 3665 patients consisting of United States and Taiwanese REVEAL-HBV cohort who were consecutive, treatment-naïve, noncirrhotic CHB patients aged ≥40 years. Patients were categorized by ALT cutoffs (≥2 × ULN vs
