Abstract
BACKGROUND Chronic hepatitis B (CHB) is endemic to Asia and is a leading cause of liver-related morbidity. The prevalence of concomitant CHB and hepatic steatosis (HS) is increasing in Asia. Non-invasive tests (NITs) including FIB-4, NFS and APRI assess fibrosis in populations with a single aetiology, but not in subjects with concomitant CHB and HS. AIM To explore the accuracy of NITs in predicting advanced fibrosis in patients with concomitant CHB and HS. METHODOLOGY This multicentre study of CHB patients who underwent liver biopsy explored clinical characteristics of these subjects, stratified by presence of HS. Fibrosis scores from NITs were compared against histological fibrosis stage in CHB subjects with and without HS. RESULTS 2262 subjects were enrolled, 74.5% were males, and the mean age was 39.5 years ±11.8 SD. 984 (44.4%) had HS, 824 (36.4%) had advanced fibrosis. In the CHB group, the AUROC for advanced fibrosis were 0.65 (95% CI 0.62-0.69) for FIB-4 and 0.63 (95% CI 0.60-0.66) for APRI. The specificities were 0.94 for FIB-4 greater than 3.25 and 0.81 for APRI greater than 1.5. In the CHBHS group, the AUROC for advanced fibrosis were 0.67 (95% CI 0.63-0.71) for FIB-4, 0.60 (95% CI 0.56-0.64) for APRI and 0.65 (95% CI 0.61-0.69) for NFS. The specificities were 0.95 for FIB-4 greater than 3.25, 0.88 for APRI greater than 1.5 and 0.99 for NFS greater than 0.675. CONCLUSION The performance of NITs to exclude advanced fibrosis did not differ greatly regardless of HS. FIB-4 and NFS have the best negative predictive values of 0.80 and 0.78, respectively, to exclude advanced fibrosis in CHBHS subjects.

Abstract
BACKGROUND AND AIMS The uptake of antiviral treatment for patients with chronic hepatitis B (CHB) has been suboptimal. We aimed to determine the secular trend of treatment uptake in the territory-wide CHB cohort in Hong Kong from 2000 to 2017 and the factors for no treatment despite fulfilling treatment criteria. METHODS Chronic hepatitis B patients under public clinics and hospitals were identified through electronic medical records. The treatment indications were defined according to the Asian-Pacific guidelines published at the time of patients' first appearance in four periods: 2000-2004, 2005-2009, 2010-2013, and 2014-2017. RESULTS There were 135 395 CHB patients were included; 1493/12472 (12.0%), 7416/43426 (17.1%), 10 129/46559 (21.8%), 8051/32 938 (24.4%) patients fulfilled treatment criteria in the four periods, respectively. The treatment uptake rate increased with time: 35.1%, 43.4%, 60.2%, and 68.6% respectively. High fibrosis indices (APRI, FIB-4, and Forns indices) appeared to be the main factors for treatment indication in non-cirrhotic patients, with over 90% fulfilling treatment criteria due to high fibrosis indices alone. Of those fulfilling treatment criteria by high fibrosis indices, less than 60% of patients (25.2%, 36.1%, 46.0%, and 58.9%, respectively) had antiviral treatment initiated. Normal platelet count (odds ratio 0.42, P < 0.001) was the independent factor associated with not initiating antiviral treatment in patients fulfilling treatment criteria. CONCLUSIONS Treatment uptake rates have been increasing over time. Normal platelet count, which reflects less advanced liver disease, precludes patients from receiving antiviral treatment even if treatment indication is fulfilled. Hence, the importance to identify non-cirrhotic patients with significant liver fibrosis should be emphasized.

Abstract
INTRODUCTION We aimed to identify gaps in knowledge, attitudes, and behaviours towards viral hepatitis among the Hong Kong public and provide insights to optimise local efforts towards achieving the World Health Organization's viral hepatitis elimination target. METHODS A descriptive, cross-sectional, self-reported web-based questionnaire was administered to 500 individuals (aged ≥18 years) in Hong Kong. Questionnaire items explored the awareness and perceptions of viral hepatitis-related liver disease(s) and associated risk factors in English or traditional Chinese. RESULTS The majority (>80%) were aware that chronic hepatitis B and/or C could increase the risks of developing liver cirrhosis, cancer, and/or failure. Only 55.8% had attended health screenings in the past 2 years, and 67.6% were unaware of their family's history of liver diseases. Misperceptions surrounding the knowledge and transmission risks of viral hepatitis strongly hint at the presence of social stigmatisation within the community. Many misperceived viral hepatitis as airborne or hereditary, and social behaviours (casual contact or dining with an infected person) as a transmission route. Furthermore, 62.4% were aware of hepatitis B vaccination, whereas 19.0% knew that hepatitis C cannot be prevented by vaccination. About 70% of respondents who were aware of mother-to-child transmission were willing to seek medical consultation in the event of pregnancy. Gaps in knowledge as well as the likelihood of seeking screening were observed across all age-groups and education levels. CONCLUSIONS Comprehensive hepatitis education strategies should be developed to address gaps in knowledge among the Hong Kong public towards viral hepatitis, especially misperceptions relevant to social stigmatisation and the importance of preventive measures, including vaccination and screening, when exposed to risk factors.

Abstract
Background Serum hepatitis B surface antigen (HBsAg) levels correlate with the duration of chronic hepatitis B virus (HBV) infection and may predict the extent of hepatic fibrosis. Methods We analyzed data from the SONIC-B database, which contains data from 8 global randomized trials and 2 large hepatology centers. Relationship between HBsAg levels and presence of significant fibrosis (Ishak 3–4) or cirrhosis (Ishak 5–6) were explored, and clinically relevant cutoffs were identified to rule out cirrhosis. Results The dataset included 2779 patients: 1866 hepatitis B e antigen (HBeAg)-positive; 322 with cirrhosis. Among HBeAg-positive patients, lower HBsAg levels were associated with higher rates of significant fibrosis (odds ratio [OR], 0.419; P < .001) and cirrhosis (OR, 0.435; P < .001). No relationship was observed among HBeAg-negative patients. Among HBeAg-positive patients, genotype-specific HBsAg cutoffs had excellent negative predictive values (>97%) and low misclassification rates (≤7.1%) and may therefore have utility in ruling out cirrhosis. Diagnostic performance of the HBsAg cutoffs was comparable among patients in whom cirrhosis could not be ruled out with fibrosis 4 (FIB-4). Conclusions Hepatitis B virus genotype-specific HBsAg cutoffs may have utility in ruling out presence of cirrhosis in HBeAg-positive patients with genotypes B, C, and D and can be an adjunct to FIB-4 to reduce the need for further testing.

Abstract
BACKGROUND The rates of hepatitis B surface antigen (HBsAg) seroclearance after stopping nucleos(t)ide analogues (NA) in European (19% in 2 years) and Asian (13% in 6 years) patients with chronic hepatitis B (CHB) vary dramatically. We evaluated the incidence of hepatitis flare and HBsAg seroclearance in hepatitis B e antigen (HBeAg)-negative Chinese CHB patients who had stopped NA. METHODS This was a territory-wide retrospective study in Hong Kong. We identified HBeAg-negative CHB patients from January 2000 to December 2017 who had stopped NA treatment for more than 3 months. Hepatitis flare was defined as ALT >2×ULN. RESULTS The 1076 patients were predominantly middle-aged men (mean age 52 years, male 74.8%) when starting NA; they stopped NA after 82 ± 35 months of treatment. At 44.3 ± 24.6 months after stopping NA, 147 (13.6%) patients had hepatitis flare, which led to resumption of NA; whereas 77 (7.2%) patients had flare but did not resume NA. Decompensation occurred in 7/914 (0.8%) patients. A total of 695 (64.6%) patients remained on NA treatment at the last visit. Eleven patients had achieved HBsAg seroclearance (6 of them had hepatitis flare and 1 of these 6 patients achieved HBsAg seroclearance after NA was restarted). Hepatic events developed in 75/695 (10.8%) patients who had NA resumed vs 43/381 (11.3%) patients who did not resume NA (P = .677). CONCLUSIONS Hepatitis flare and retreatment were common in HBeAg-negative CHB patients who stopped NA treatment; whereas HBsAg seroclearance rarely occurred. Stopping NA to achieve functional cure should not be recommended at this moment.

Abstract
Achieving hepatitis B e antigen (HBeAg) seroconversion is a satisfactory endpoint during antiviral treatment for chronic hepatitis B (CHB). This study aimed to develop and validate a novel scoring system to predict HBeAg seroconversion during entecavir (ETV) treatment. A total of 526 patients with HBeAg-positive CHB treated with ETV for at least 1 year were randomly assigned to the training and validation cohorts. Baseline parameters including hepatitis B virus DNA, hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), and alanine aminotransferase level were quantified. Patients who achieved HBeAg seroconversion were compared with those without HBeAg seroconversion. A prediction model was established to predict HBeAg seroconversion during ETV treatment. After a median follow up of 2.67 years, 93 (36.0%) and 87 (32.5%) patients in the training and validation cohorts developed HBeAg seroconversion. A prediction score composed of age, HBsAg and HBcAb quantification was derived. Areas under receiver operating characteristic curve at 5 years of this prediction score were 0.70 and 0.72 in the training and validation cohorts. By using the dual cutoff values of 0.28 and 0.58, the model was endowed with high sensitivity and specificity to exclude or identify patients developing HBeAg seroconversion (90.3% sensitivity and 90.2% specificity in the training cohort as well as 92.8% sensitivity and 84.4% specificity in the validation cohort, respectively). A novel prediction score that uses baseline clinical variables was developed and validated. The score accurately estimates the probabilities of developing HBeAg seroconversion at 5-years ETV therapy in patients with CHB.

Abstract
BACKGROUND Peginterferon induces off-treatment responses in approximately one-third of patients with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B. AIM To develop an easy-to-use baseline prediction score to identify hepatitis B virus (HBV) genotype B-/C-infected HBeAg-positive Asian patients likely to respond to peginterferon alfa-2a. METHODS Generalised additive models, multiple logistic regression (MLR) analysis and internal validation methods were applied to data from 647 HBeAg-positive patients from China, Hong Kong and Taiwan to develop a scoring system to predict response 24 weeks after completing a 48-week course of peginterferon alfa-2a. RESULTS Five baseline factors (age, sex, alanine aminotransferase ratio, hepatitis B surface antigen (HBsAg) level and HBV DNA level) were retained in the final MLR for HBeAg seroconversion and used to develop a scoring system from 0 to 7. Among patients with scores of 0-1, 2-3, 4 or ≥5, HBeAg seroconversion was achieved in 6.4% (6/94), 23.0% (61/265), 36.4% (67/184) and 54.8% (57/104), respectively, and a combined response (HBeAg seroconversion plus HBV DNA <2000 IU/mL) in 5.3% (5/94), 12.8% (34/265), 25.0% (46/184) and 36.5% (38/104), respectively. Among patients with scores of 0-1, 2-3, 4 or ≥5, 57.0% (53/93), 12.3% (31/253), 3.4% (6/178) and 1.0% (1/100) had HBsAg ≥20 000 IU/mL at treatment Week 12; only 3/91 (3.3%) with HBsAg ≥20 000 IU/mL experienced a combined response at 24 weeks post-treatment (negative predictive value = 97% [88/91]). CONCLUSION A pre-treatment scoring system using readily available baseline characteristics identifies HBeAg-positive Asian patients likely to experience sustained HBeAg seroconversion after treatment with peginterferon alfa-2a.

Abstract
BACKGROUND In the large randomised NEPTUNE study, peginterferon alfa-2a 180 μg/wk for 48 weeks produced higher hepatitis B e antigen (HBeAg) seroconversion rates 24 weeks post-treatment (36%) than a lower dose (90 μg/wk) and/or shorter duration (24 weeks) (range 14%-26%). AIM To determine seroconversion rates 5 years after completion of treatment in NEPTUNE. METHODS HBeAg-positive patients who completed 24 weeks' follow-up in NEPTUNE (with peginterferon alfa-2a 90 μg/wk × 24 weeks [group 1]; 180 μg/wk × 24 weeks [2]; 90 μg/wk × 48 weeks [3] or 180 μg/wk × 48 weeks [4]) were followed up. RESULTS Three hundred and eighty three of the 544 patients in the original study were enrolled in the long-term follow-up study. Many patients (196 overall; more in groups 1-3 than 4) received nucleos(t)ide analogues or immunomodulators during follow-up, and more patients had missing data at year 5 in groups 2 and 4 (48 weeks, 50/112) than in groups 1 and 3 (24 weeks, 23/103), which confounds the planned per-protocol analysis. HBeAg seroconversion rates in groups 1, 2, 3 and 4 at year 5 were 47.5%, 50.7%, 52.2% and 67.1%, respectively, (odds ratio for group 4 versus 1-3: 2.02; 95% CI 1.21, 3.38), using multiple imputation methods for missing measurements. CONCLUSION Seroconversion rates are durable for up to 5 years after completion of peginterferon alfa-2a therapy and, consistent with NEPTUNE, the results suggest that the licensed regimen (180 μg × 48 weeks) is more efficacious for HBeAg-positive patients than a lower dose and/or shorter treatment duration.

Abstract
Chronic, untreated hepatitis C virus (HCV) infection is associated with a poor clinical prognosis and a detrimental impact on patients' lives, including on work productivity. To estimate the value of productivity losses due to genotype 1 (GT1) HCV infection in Hong Kong, Singapore, South Korea and Taiwan and to estimate the potential productivity gains associated with treating patients with ledipasvir/sofosbuvir (LDV/SOF) therapy, an economic model was developed with a time horizon of 1 year. Hepatitis C virus patients entered the model at 12 weeks post-treatment, having achieved or not achieved sustained virological response (SVR). Absenteeism and presenteeism rates were taken from a pooled analysis of data from the ION 1-3 studies. These rates were converted into hours of lost productivity, multiplied by the average wage and applied to the total employed, adult GT1 population in each country. Results were compared assuming no treatment, and assuming all patients were treated with LDV/SOF. Total productivity losses due to untreated HCV were: $11.3 million, $17.1 m, $146.0 m and $349.1 m in Hong Kong, Singapore, South Korea and Taiwan. LDV/SOF treatment resulted in economic gains of $4.5 m, $6.8 m, $58.7 m and $138 m, respectively. These gains were due to reduced presenteeism. The results were sensitive to changes in the prevalence of HCV and the average wage. In conclusion, productivity losses due to untreated HCV infection represent a substantial economic burden. By instituting universal HCV treatment with LDV/SOF (or other therapies with high SVR rates), productivity gains can be achieved.

Abstract
Due to the introduction of newer, more efficacious treatment options, there is a pressing need for policy makers and public health officials to develop or adapt national hepatitis C virus (HCV) control strategies to the changing epidemiological landscape. To do so, detailed, country-specific data are needed to characterize the burden of chronic HCV infection. In this study of 17 countries, a literature review of published and unpublished data on HCV prevalence, viraemia, genotype, age and gender distribution, liver transplants and diagnosis and treatment rates was conducted, and inputs were validated by expert consensus in each country. Viraemic prevalence in this study ranged from 0.2% in Hong Kong to 2.4% in Taiwan, while the largest viraemic populations were in Nigeria (2 597 000 cases) and Taiwan (569 000 cases). Diagnosis, treatment and liver transplant rates varied widely across the countries included in this analysis, as did the availability of reliable data. Addressing data gaps will be critical for the development of future strategies to manage and minimize the disease burden of hepatitis C.

Abstract
Factors influencing the morbidity and mortality associated with viremic hepatitis C virus (HCV) infection change over time and place, making it difficult to compare reported estimates. Models were developed for 17 countries (Bahrain, Bulgaria, Cameroon, Colombia, Croatia, Dominican Republic, Ethiopia, Ghana, Hong Kong, Jordan, Kazakhstan, Malaysia, Morocco, Nigeria, Qatar and Taiwan) to quantify and characterize the viremic population as well as forecast the changes in the infected population and the corresponding disease burden from 2015 to 2030. Model inputs were agreed upon through expert consensus, and a standardized methodology was followed to allow for comparison across countries. The viremic prevalence is expected to remain constant or decline in all but four countries (Ethiopia, Ghana, Jordan and Oman); however, HCV-related morbidity and mortality will increase in all countries except Qatar and Taiwan. In Qatar, the high-treatment rate will contribute to a reduction in total cases and HCV-related morbidity by 2030. In the remaining countries, however, the current treatment paradigm will be insufficient to achieve large reductions in HCV-related morbidity and mortality.

Abstract
The hepatitis C virus (HCV) epidemic was forecasted through 2030 for 17 countries in Africa, Asia, Europe, Latin America and the Middle East, and interventions for achieving the Global Health Sector Strategy on viral hepatitis targets-"WHO Targets" (65% reduction in HCV-related deaths, 90% reduction in new infections and 90% of infections diagnosed by 2030) were considered. Scaling up treatment and diagnosis rates over time would be required to achieve these targets in all but one country, even with the introduction of high SVR therapies. The scenarios developed to achieve the WHO Targets in all countries studied assumed the implementation of national policies to prevent new infections and to diagnose current infections through screening.

Abstract
BACKGROUND In patients with chronic hepatitis B, tenofovir disoproxil fumarate (TDF) plus pegylated interferon (PEG-IFN) for 48-weeks results in higher rates of hepatitis B surface antigen (HBsAg) loss than either monotherapy. AIM To identify baseline and on-treatment factors associated with HBsAg loss at Week 72 and provide a model for predicting HBsAg loss in patients receiving combination therapy for 48 weeks. METHODS A secondary analysis of data from an open-label study where patients were randomised to TDF (300 mg/day, oral) plus PEG-IFN (PI, 180 μg/week, subcutaneous) for 48 weeks (TDF/PI-48w); TDF plus PEG-IFN for 16 weeks, TDF for 32 weeks (TDF/PI-16w+TDF-32w); TDF for 120 weeks (TDF-120w) or PEG-IFN for 48 weeks (PI-48w). Logistic regression methods were used to identify models that best predicted HBsAg loss at Week 72. RESULTS Rates of HBsAg loss at Week 72 were significantly higher in the TDF/PI-48w group (6.5%) than in the TDF/PI-16w+TDF-32w (0.5%), TDF-120w (0%) and PI-48w (2.2%) groups (P = 0.09). The only baseline factor associated with response was genotype A. HBsAg decline at Week 12 or 24 of treatment was associated with HBsAg loss at Week 72 (P < 0.001). HBsAg decline >3.5 log10 IU/mL at Week 24 in the TDF/PI-48w group resulted in a positive predictive value of 85% and a negative predictive value of 99% for HBsAg loss at Week 72. CONCLUSIONS HBsAg decline at Week 24 of TDF plus PEG-IFN combination therapy may identify patients who, after completing 48 weeks of treatment, have a better chance of achieving HBsAg loss at Week 72.

Abstract
BACKGROUND Nucleos(t)ide analogues (NUCs) for chronic hepatitis B treatment achieve high rates of viral suppression and are generally well tolerated. Entecavir (ETV) and tenofovir disoproxil fumarate (TDF) are the currently preferred first-line agents. The safety of these agents in clinical practice is particularly relevant since long-term treatment is usually required. AIM To summarise and critically discuss recent real-world evidence on the safety of treatment with ETV or TDF in hepatitis B virus (HBV)-monoinfected patients. METHODS PubMed and conference proceedings up to 15th June 2015 were searched using the terms ((((Hepatitis_B) OR HBV) AND ((tenofovir) OR entecavir)) AND (((lactic_acidosis) OR bone) OR renal)). RESULTS In selected populations included in registration studies, both ETV and TDF were well tolerated with no clinically significant renal toxicity or lactic acidosis. Growing 'real-world' clinical experience with these agents includes some reports of ETV-associated lactic acidosis and TDF-associated renal impairment; however, evidence from cohort studies appears to be conflicting. In the case of ETV-related lactic acidosis, a small number of cases have been reported, all in patients with decompensated cirrhosis. The degree of association between TDF treatment and changes in markers of renal function varies between studies: discrepancies may result from the use of different definitions and cut-offs for reporting renal toxicities, and differences in patient populations. CONCLUSIONS Pre-treatment and on-treatment monitoring of eGFR and phosphorus, with prompt appropriate dose adjustment or treatment switch can minimise the impact of NUC renal toxicity. Standardisation of measures of renal impairment and identification of early molecular markers remain an unmet need.

Abstract
BACKGROUND In Hong Kong, most patients with hepatitis C virus (HCV) have either genotype 6a or 1b infection. AIM To evaluate the efficacy and safety of sofosbuvir with ribavirin in treatment-naïve patients in Hong Kong with HCV genotype 1 or 6. METHODS In an open-label study, patients were randomised to sofosbuvir 400 mg once daily plus ribavirin 1000-1200 divided twice daily for 12 (n = 10), 16 (n = 11) or 24 (n = 10) weeks. The primary endpoint was the percentage of patients with HCV RNA < LLOQ (lower limit of quantification, 25 IU/mL) 12 weeks after cessation of therapy (SVR12). RESULTS All 31 patients (20 HCV genotype 1 and 11 genotype 6) had HCV RNA < LLOQ by Week 4 of treatment and at their last on-treatment visit. SVR12 rates were high in all treatment groups: 100% (10/10) for 12 weeks, 100% (11/11) for 16 weeks and 90% (9/10) for 24 weeks of therapy. The only patient who did not reach SVR12 had genotype 1 HCV and relapsed at post-treatment Week 4. Sofosbuvir with ribavirin was generally well tolerated. The most common adverse events were malaise (13%) and upper respiratory tract infection (13%), followed by anaemia (10%). No patients experienced serious adverse events. One patient discontinued treatment at Week 16 because of an adverse event. The event, upper respiratory tract infection, was not considered treatment related by the investigator. This subject achieved SVR12. CONCLUSIONS The all-oral regimen sofosbuvir plus ribavirin is effective in treatment-naïve patients in Hong Kong with genotype 1 or 6 HCV. TRIAL REGISTRATION NUMBER NCT02021643.

Abstract
Worldwide, some 240 million people have chronic hepatitis B virus (HBV), with the highest rates of infection in Africa and Asia. Our understanding of the natural history of HBV infection and the potential for therapy of the resultant disease is continuously improving. New data have become available since the previous APASL guidelines for management of HBV infection were published in 2012. The objective of this manuscript is to update the recommendations for the optimal management of chronic HBV infection. The 2015 guidelines were developed by a panel of Asian experts chosen by the APASL. The clinical practice guidelines are based on evidence from existing publications or, if evidence was unavailable, on the experts' personal experience and opinion after deliberations. Manuscripts and abstracts of important meetings published through January 2015 have been evaluated. This guideline covers the full spectrum of care of patients infected with hepatitis B, including new terminology, natural history, screening, vaccination, counseling, diagnosis, assessment of the stage of liver disease, the indications, timing, choice and duration of single or combination of antiviral drugs, screening for HCC, management in special situations like childhood, pregnancy, coinfections, renal impairment and pre- and post-liver transplant, and policy guidelines. However, areas of uncertainty still exist, and clinicians, patients, and public health authorities must therefore continue to make choices on the basis of the evolving evidence. The final clinical practice guidelines and recommendations are presented here, along with the relevant background information.

Abstract
BACKGROUND The effect of antiviral therapy on the post-hepatectomy long-term survival in patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) remains uncertain. AIM To evaluate the effect of antiviral therapy on post-hepatectomy survival and recurrence in patients with HBV-related HCC. METHODS This was a prospective-retrospective study of a total of 404 patients who underwent hepatectomy for HBV-related HCC in a tertiary academic hospital. Data on patient and tumour characteristics, tumour recurrence, treatment for recurrence and survival were compared between antiviral and no antiviral groups. RESULTS Patient's and tumour characteristics were comparable between the two groups, except a higher proportion of patients with cirrhosis in the antiviral group. With a mean follow-up time of 52.4 months, antiviral group had a better 5-year overall survival (66.7% vs. 56.0%, P = 0.001) while there was no significant difference in the 5-year disease-free survival (44.7% vs. 38.1%, P = 0.166). Use of antiviral therapy was associated with better liver function reserve at the time of recurrence and a greater proportion of patients could receive curative treatment for recurrence (38.5% vs. 24.3%, P = 0.041). There was no significant different in the hazard ratios of patients who started antiviral therapy before or after operation (P = 0.054). CONCLUSIONS Use of antiviral therapy improves the long-term post-hepatectomy survival in patients with HBV-related HCC. With a better liver function reserve at the time of recurrence, a greater proportion of patients in antiviral group could receive curative treatment for recurrence.

Abstract
BACKGROUND Kinetics of serum hepatitis B surface antigen (HBsAg) level in hepatitis B e antigen (HBeAg)-negative chronic hepatitis B patients presented with severe reactivation and received oral antiviral therapy is unknown. We aimed to investigate the kinetics of HBsAg level among these patients. METHODS HBeAg-negative patients on antiviral therapy with follow-up for 2 years were studied. Those presented with severe reactivation (alanine aminotransferase [ALT] ≥5 times of normal) were compared to those with mild hepatitis. Serum HBsAg level was measured by Elecsys HBsAg II Quant assay (Roche) at baseline and 6-monthly. RESULTS A total of 192 (74 severe reactivation) patients were studied. Eighty-one (42%), 74 (39%) and 37 (19%) patients were on lamivudine, entecavir and telbivudine, respectively. Forty-four (23%) patients had early HBsAg decline, that is, ≥0.5 log10 reduction, at month 6. Patients with severe reactivation had higher serum baseline ALT (1,415 ±897 versus 73 ±39 IU/l), HBV DNA (6.4 ±1.6 versus 5.2 ±1.2 log10 IU/ml) and HBsAg (3.3 ±1.0 versus 2.9 ±0.6 log10 IU/ml), as well as an earlier HBsAg decline (50% versus 6%; all P<0.001) than those without. The HBsAg change of patients with severe reactivation was higher at months 0-6 (-0.58 ±-1.26 versus -0.01 ±-0.26 log10 IU/ml; P<0.001) but then became comparable from months 6-24 (-0.19 ±-0.60 versus -0.13 ±-0.19 log10 IU/ml; P=0.85), compared to those presented with mild hepatitis. CONCLUSIONS Patients who presented with severe reactivation of HBeAg-negative hepatitis were more likely to develop early HBsAg decline during antiviral therapy. It may indicate a transient strong immune clearance with rapid initial reduction in serum HBsAg, which cannot be sustained due to a faster clearance of serum HBsAg.

Abstract
UNLABELLED On-treatment levels of hepatitis B surface antigen (HBsAg) may predict response to peginterferon (PEG-IFN) therapy in chronic hepatitis B (CHB), but previously proposed prediction rules have shown limited external validity. We analyzed 803 HBeAg-positive patients treated with PEG-IFN in three global studies with available HBsAg measurements. A stopping-rule based on absence of a decline from baseline was compared to a prediction-rule that uses HBsAg levels of <1,500 IU/mL and >20,000 IU/mL to identify patients with high and low probabilities of response. Patients with an HBsAg level <1,500 IU/mL at week 12 achieved response (HBeAg loss with HBV DNA <2,000 IU/mL at 6 months posttreatment) in 45%. At week 12, patients without a decline in HBsAg achieved a response in 14%, compared to only 6% of patients with HBsAg >20,000 IU/mL, but performance varied across HBV genotype. In patients treated with PEG-IFN monotherapy (n = 465), response rates were low in patients with genotypes A or D if there was no decline of HBsAg by week 12 (negative predictive value [NPV]: 97%-100%), and in patients with genotypes B or C if HBsAg at week 12 was >20,000 IU/mL (NPV: 92%-98%). At week 24, nearly all patients with HBsAg >20,000 IU/mL failed to achieve a response, irrespective of HBV genotype (NPV for response and HBsAg loss 99% and 100%). CONCLUSION HBsAg is a strong predictor of response to PEG-IFN in HBeAg-positive CHB. HBV genotype-specific stopping-rules may be considered at week 12, but treatment discontinuation is indicated in all patients with HBsAg >20,000 IU/mL at week 24, irrespective of HBV genotype.

Abstract
In the phase-III GLOBE/015 studies, telbivudine demonstrated superior efficacy vs lamivudine during 2-year treatment in HBeAg-positive and HBeAg-negative chronic hepatitis B (CHB). After completion, 847 patients had an option to continue telbivudine treatment for further 2 years. A total of 596 (70%) of telbivudine-treated patients, who were serum HBV DNA positive or negative and without genotypic resistance to telbivudine at the end of the GLOBE/015 trials, were enrolled into a further 2-year extension study. A group of 502 patients completed 4 years of continuous telbivudine treatment and were included in the telbivudine per-protocol population. Amongst 293 HBeAg-positive patients, 76.2% had undetectable serum HBV DNA and 86.0% had normal serum ALT at the end of 4 years. Notably, the cumulative rate of HBeAg seroconversion was 53.2%. Amongst 209 HBeAg-negative patients, 86.4% had undetectable HBV DNA and 89.6% had normal serum ALT. In patients who had discontinued telbivudine treatment due to HBeAg seroconversion, the HBeAg response was durable in 82% of patients (median 111 weeks of off-treatment follow-up). The cumulative 4-year resistance rate was 10.6% for HBeAg-positive and 10.0% for HBeAg-negative patients. Most adverse events were mild or moderate in severity and transient. Renal function measured by estimated glomerular filtration rate (eGFR) increased by 14.9 mL/min/1.73 m(2) (16.6%) from baseline to 4 years (P < 0.0001). In conclusion, in HBeAg-positive and HBeAg-negative CHB patients without resistance after 2 years, two additional years of telbivudine treatment continued to provide effective viral suppression with a favourable safety profile. Moreover, telbivudine achieved 53% of HBeAg seroconversion in HBeAg-positive patients.

Abstract
Patients with decompensated cirrhosis owing to chronic hepatitis B viral (HBV) infection have a high morbidity/mortality rate, and the treatment remains a challenge. We studied the safety and efficacy of telbivudine and lamivudine in such patients. This noninferiority, double-blind trial randomized 232 treatment-naive patients with decompensated HBV (1:1) in 80 academic hospitals to receive once-daily telbivudine 600 mg or lamivudine 100 mg for 104 weeks. Primary composite endpoint was proportion of patients with HBV DNA <10 000 copies/mL, normal alanine aminotransferase (ALT) and Child-Turcotte-Pugh score improvement/stabilization at week 52. Response rates using a post hoc modified endpoint (HBV DNA <300 copies/mL [57 IU/mL] and ALT normalization) in intent-to-treat analysis (missing = failure) were 56.3%vs 38.0% after 76 weeks (P = 0.018) and 45.6%vs 32.9% after 104 weeks (P = 0.093) for telbivudine vs lamivudine. Telbivudine treatment was an independent predictive factor for HBV DNA <300 copies/mL and ALT normalization (P = 0.037). Response rates with protocol-defined composite endpoint in intent-to-treat analysis (M = F) were 56.2 vs 54.0% (noninferiority not achieved) and 39.1%vs 36.4% (noninferiority achieved) in telbivudine and lamivudine groups at 52 and 104 weeks. Telbivudine treatment was associated with a significant improvement in glomerular filtration rate compared to lamivudine treatment and was also associated with a trend for improvement in survival (87%vs 79%). No cases of lactic acidosis were reported. Telbivudine compared to lamivudine was associated with a higher rate of patients with both viral suppression and ALT normalization, a trend towards a higher rate of survival and significant improvement in glomerular filtration.

Abstract
BACKGROUND The timing of antiviral therapy cessation in hepatitis B e antigen (HBeAg)-negative patients is controversial. Here, we aimed to investigate the role of HBV DNA and hepatitis B surface antigen (HBsAg) monitoring to predict off-treatment sustained response. METHODS A total of 53 HBeAg-negative chronic hepatitis B patients who received lamivudine for 34 ±23 (range 12-76) months and had lamivudine stopped for 47 ±35 months were studied. Primary outcome was sustained response, defined as HBV DNA≤200 IU/ml, at 12 months post-treatment (SR-12). RESULTS A total of 9 (17%) patients achieved SR-12. HBV DNA at baseline, month 6 and end of treatment had no association with SR-12. HBsAg levels tended to decrease more significantly during treatment among SR-12 responders. At the end of treatment, both HBsAg ≤2 log IU/ml and reduction by >1 log from baseline had sensitivity, specificity, positive and negative predictive values for SR-12 of 78%, 96%, 78% and 96%, respectively. All 5 patients with HBsAg≤2 log IU/ml and reduction >1 log at the end of treatment achieved SR-12 and all 40 patients with HBsAg>2 log IU/ml and reduction ≤1 log did not have SR-12. The cumulative probability of sustained response and HBsAg clearance at 5 years among patients with HBsAg≤2 log IU/ml were 88% and 72%, respectively, that among patients with HBsAg reduction >1 log were 74% and 61%, respectively. CONCLUSIONS Monitoring of HBsAg level can guide the timing of stopping lamivudine in HBeAg-negative chronic hepatitis B.

Abstract
UNLABELLED As there is currently a lack of consensus on the most appropriate dose and duration of peginterferon alfa-2a (PEG-IFNα-2a) therapy in hepatitis B e antigen (HBeAg)-positive patients, the efficacy and safety of either 24 or 48 weeks' duration and 90 μg/week or 180 μg/week doses were compared. HBeAg-positive patients (n = 544; 34% genotype B, 51% genotype C) were randomized to receive PEG-IFNα-2a (2 × 2 factorial design) for 24 or 48 weeks and at 90 μg/week or 180 μg/week and included in the per-protocol population. The primary efficacy endpoint of the noninferiority study was HBeAg seroconversion 6 months posttreatment. The prespecified odds ratio (OR) noninferiority margin was 1.88 with a one-sided significance level of 0.025. The highest rates of HBeAg seroconversion 6 months posttreatment were in the 180/48 arm (36.2% versus 14.1%-25.8% in the other arms). When the dose and duration arms were pooled, the OR for noninferiority of 24 weeks versus 48 weeks was 2.17 (95% confidence interval [CI] 1.43, 3.31; P = 0.749) and for 90 μg versus 180 μg was 1.79 (95% CI 1.18, 2.72; P = 0.410). As the upper limit of the 95% CI of the ORs were >1.88, 24 weeks were inferior to 48 weeks and 90 μg/week was inferior to 180 μg/week. The highest rates of response in the 180/48 arm were achieved by patients with HBsAg <1,500 IU/mL at Week 12 (58%) or Week 24 (57%), whereas patients with HBsAg >20,000 IU/mL did not respond. Adverse events were typical of those associated with PEG-IFNα-2a. CONCLUSION Compared with lower doses and shorter durations, the licensed PEG-IFNα-2a treatment regimen (180 μg/48 weeks) was the most efficacious and beneficial for HBeAg-positive patients predominantly infected with hepatitis B virus genotypes B or C.

Abstract
BACKGROUND Previous studies suggested that a finite course of peginterferon alfa-2a may offer an alternative rescue therapy for patients with lamivudine resistance. However, because of the limitation of study design and small sample size, it is difficult to make definitive conclusion. AIM To explore the role of peginterferon alfa-2a, in the rescue treatment of HBeAg-positive chronic hepatitis B patients with lamivudine resistance. METHODS In this randomised study, chronic hepatitis B patients with lamivudine resistance were treated with peginterferon alfa-2a for 48 weeks (n=155) or adefovir for 72 weeks (n=80). All enrolled patients were treated with lamivudine for the first 12weeks. RESULTS At 6 months posttreatment, 14.6% (18/123) of peginterferon alfa-2a-treated patients achieved HBeAg seroconversion, in contrast to 3.8% (3/80) of adefovir-treated patients after 72 weeks continuous therapy (P=0.01). For peginterferon alfa-2a-treated patients, the rate of HBeAg seroconversion at week 72 was significantly higher in patients who had HBsAg decline >0.5 Log(10) IU/mL from baseline at week 24, compared with patients with HBsAg decline ≤0.5 Log(10) IU/mL from baseline at week 24 (25.5% vs. 7.7%, P=0.01). After 72 weeks continuous adefovir treatment, 22.5% of patients achieved HBV DNA <80 IU/mL, compared with 10.6% in peginterferon alfa-2a-treated patients at 6months off-treatment (P=0.02). CONCLUSIONS Overall, the response to peginterferon alfa-2a among patients with lamivudine resistance was suboptimal. HBeAg seroconversion rate at week 72 by 48 weeks peginterferon alfa-2a treatment was higher than continuous adefovir therapy. Monitoring HBsAg levels can help to predict response to peginterferon alfa-2a.

Abstract
BACKGROUND AND AIM Liver stiffness measurement (LSM) with transient elastography is a non-invasive and reliable test for liver fibrosis. However a small proportion of patients may have unreliable LSM or LSM failure. The aim of the present study was to investigate the factors associated with unreliable LSM or LSM failure in Chinese patients. METHODS We prospectively recruited liver patients for LSM. Unreliable LSM was defined as < 10 valid shots, an interquartile range (IQR)/LSM > 30%, or a success rate < 60%. LSM failure was defined as zero valid shots. RESULTS Among 3205 patients with LSM, 371 (11.6%) and 88 (2.7%) had unreliable LSM and LSM failure, respectively. The rates started to increase when body mass index (BMI) ≥ 28.0 kg/m(2) . Comparing patients with BMI ≥ 28.0-29.9 kg/m(2) versus those with BMI ≥ 30.0 kg/m², the rates of unreliable LSM (16.4% vs 18.9%; P = 0.62) and LSM failure (11.8% vs 17.8%; P = 0.16) were similar. BMI ≥ 28.0 kg/m² was the most important factor associated with unreliable LSM (odds ratio [OR] = 2.9, 95% confidence interval [CI] = 2.1-3.9, P < 0.0001) and LSM failure (OR = 10.1, 95% CI = 6.4-14.2, P < 0.0001). Central obesity, defined as waist circumference > 80 cm in women and > 90 cm in men, was another independent risk factor of unreliable LSM (OR = 1.3, 95% CI = 1.0-1.6, P = 0.04) and LSM failure (OR = 5.8, 95% CI = 2.9-11.5, P < 0.0001). CONCLUSION BMI ≥ 28.0 kg/m² and central obesity were the independent risk factors of unreliable LSM and LSM failure in Chinese, and these rates were significantly higher in patients with extreme BMI.

Abstract
Hepatitis B virus (HBV) covalently closed circular DNA (cccDNA) is responsible for viral persistence. This study aimed to investigate the serum surrogate markers for cccDNA and to evaluate the intrahepatic viral events associated with disease activity in HBeAg-negative chronic hepatitis B patients. Thirty-three treatment-naïve patients with a negative HBeAg who had a liver biopsy were studied. Active disease was defined as a serum alanine aminotransferase >40 IU/L and a serum HBV DNA >10,000 copies/ml. This study showed significant correlation between serum HBV DNA and both log cccDNA (r = 0.41, P = 0.018) and log total intrahepatic HBV DNA (r = 0.71, P < 0.0001). No significant correlation was observed between serum HBsAg and log cccDNA (P = 0.15) or log total intrahepatic HBV DNA (P = 0.97). Fourteen and 19 patients had inactive and active disease, respectively. The median log cccDNA and log total intrahepatic HBV DNA (copies/10(6) cells) were significantly higher in patients with active disease compared with those with inactive disease (4.11 vs. 3.53, P = 0.03 and 5.46 vs. 4.64, P < 0.001, respectively). The HBV replicative efficiency, defined as the ratio of serum HBV DNA to cccDNA, was approximately 20% higher in patients with active disease. No significant difference was observed in the HBsAg levels and the ratio of serum HBsAg to cccDNA between the two groups. In conclusion, serum HBV DNA, but not HBsAg, reflects the amount of cccDNA and the replication efficiency of HBV in patients with HBeAg-negative chronic hepatitis B.

Abstract
The combination of pegylated-interferon (PEG-IFN)/ribavirin is currently the standard of care antiviral treatment for chronic hepatitis C (CHC), but optimal results require an individual approach. Key issues are to deliver doses that confer optimal antiviral efficacy against hepatitis C virus (HCV) for a time sufficient to minimise relapse. Viral monitoring during therapy guides the subsequent treatment course, particularly HCV RNA results at 4 weeks (rapid viral response [RVR]) and 12 weeks (complete early viral response [cEVR]). There is strong evidence that for most patients with genotypes 2 or 3 HCV infection, RVR allows truncation of treatment to 16 weeks, provided ribavirin dose is weight-based. However, those patients with cirrhosis, insulin resistance/diabetes or older than 50 years need 6-12 months treatment. For "difficult-to-treat" CHC (genotypes 1 and 4), RVR is infrequent (approximately 15% in European studies), but allows treatment to be truncated from 48 to 24 weeks. Without RVR, there is some evidence that longer treatment (72 weeks) improves sustained viral response (SVR). However, "induction dosing" first 12 weeks of PEG-IFN clearly does not improve SVR. To prevent dose reductions and complete therapy, it is critical to detect and treat depression and other disabling side-effects, including judicious use of growth factors for severe anemia or neutropenia and possibly, thrombocytopenia. Another potentially important aspect may be attempts to counter central obesity and insulin resistance, which confer suboptimal antiviral response with any HCV genotype. Treatment partnerships with specialist nurses, psychological therapists and other healthcare workers are also essential for optimal individual management of patients with CHC.

Abstract
BACKGROUND Non-invasive assessments of liver fibrosis in chronic hepatitis B were well established. AIM To develop a combined algorithm of liver stiffness measurement (LSM) and serum test formula to predict advanced liver fibrosis in chronic hepatitis B. METHODS We reported an alanine aminotransferase (AST)-based LSM algorithm for liver fibrosis in 156 chronic hepatitis B patients, which formed the training cohort to evaluate the performance of APRI (AST-to-platelet-ratio-index), Forns index, FIB-4 and Fibroindex against liver histology. The best combined LSM-serum formula algorithm would be validated in another cohort of 82 chronic hepatitis B patients. RESULTS In the training cohort, LSM has the best performance of diagnosing advanced (> or =F3) fibrosis [area under the receiver operating characteristics curve (AUROC) 0.88, 95% confidence interval (CI) 0.85-0.91], while Forns index has the best performance among the various serum test formulae (AUROC 0.70, 95% CI 0.62-0.78). In the combined algorithm, low LSM or low Forns index could be used to exclude advanced fibrosis as both of them had high sensitivity (>90%). To confirm advanced fibrosis, agreement between high LSM and high Forns index could improve the specificity (from 99% to 100% and from 87% to 98% in the training and validation cohorts respectively). CONCLUSION A combined LSM-Forns algorithm can improve the accuracy to predict advanced liver fibrosis in chronic hepatitis B.

Abstract
The ultimate goal of treatment for chronic hepatitis B is to reduce liver-related complications and mortality. Sustained hepatitis B e antigen (HBeAg) seroconversion and hepatitis B surface antigen (HBsAg) clearance 6-12 months after stopping treatment are the short-term surrogate outcomes for interferon or peginterferon therapy. As most patients require long-term nucleos(t)ide analogue treatment, which also has the risk of drug resistance in the case of incomplete viral suppression, maintained hepatitis B virus (HBV) DNA suppression to an undetectable level is the appropriate surrogate outcome. Because no antiviral treatment is perfect, it is desirable for treatment response to be predicted and the treatment regimen modified accordingly. At baseline, high ALT and low HBV DNA levels can predict response to both (peg)interferon and nucleos(t)ide analogues. Genotype A HBV responds best to peginterferon but HBV genotype has no predictive value for nucleos(t)ide analogue treatment. HBV DNA is a good on-treatment predictor of response for nucleos(t)ide analogues but not for (peg)interferon. The data supporting the use of quantitative HBsAg and HBeAg to predict response to peginterferon is stronger than that for nucleos(t)ide analogues. In conclusion, predictors of response are useful to provide the most appropriate antiviral therapy to the most suitable patients, in order to achieve the best response and improve the clinical outcome of chronic hepatitis B patients.

Abstract
BACKGROUND AND AIMS The proposed cut-off values for the degree of fibrosis as assessed by liver stiffness measurement (LSM) might not be applicable in severe acute exacerbation of chronic hepatitis B (CHB). We aimed to assess the effect of necroinflammatory activity on LSM in this condition. METHODS We prospectively recruited consecutive patients with severe acute exacerbation of CHB (alanine aminotransferase or ALT > 10x upper limit of normal). The relationship of ALT levels and LSM were serially assessed and liver biopsy was carried out after ALT normalization. RESULTS Eleven patients (10 male, median age 43 years) were followed up for 25 weeks; nine patients received antiviral therapy. Overall, LSM was positively correlated with ALT levels (r = 0.67, P < 0.001). At initial presentation, the median serum ALT and LSM was 1136 (581-2210) IU/L and 26.3 (11.1-33.3) kPa. A progressive reduction in LSM was observed during subsequent visits in parallel with the reduction of ALT levels. At the last visit, the median ALT was 27 (11-52) IU/L and LSM was 7.7 (4.7-10.8) kPa. Among the five patients who had liver biopsy carried out at week 25, four patients had F2 fibrosis (LSM 5.7-8.1 kPa) and one patient had F3 fibrosis (LSM 8.6 kPa). CONCLUSIONS LSM using transient elastography with the current proposed cut-off values might misdiagnose liver cirrhosis in patients suffering from severe acute exacerbation of CHB. LSM should be assessed after normalization of ALT levels in order to accurately assess the degree of fibrosis.

Abstract
BACKGROUND Chronic hepatitis B (CHB) infection leads to development of hepatocellular carcinoma (HCC), but the effects of treatment in preventing HCC are not clear. AIM To study the effects of interferon (IFN) or nucleoside/tide analogue (NA) on the risk of developing HCC in CHB patients. METHODS Randomized trials, case-control and cohort studies were retrieved from five electronic databases and international conferences over the past 10 years. Relative risks (RRs) of HCC with or without treatment were studied. RESULTS Twelve studies (n = 2742) enrolling patients treated by IFN vs. control showed that the risk of HCC after treatment was reduced by 34% (RR: 0.66, 95% CI: 0.48-0.89). Benefit is more significant among patients with early cirrhosis than among those without cirrhosis. Five studies (n = 2289) compared patients treated by NA with control. The risk of HCC after treatment was reduced by 78% (RR: 0.22, 95% CI: 0.10-0.50). HBeAg-positive patients showed more significantly reduced HCC risk with treatment. Patients without cirrhosis benefited more from NA than those with cirrhosis. Resistance to NA has obviated the benefit of the treatment. CONCLUSIONS IFN or NA treatment significantly reduces risk of HCC. While IFN benefited patients with cirrhosis, NA benefited patients with no cirrhosis and HBeAg-positive CHB infection.

Abstract
BACKGROUND AND AIM As liver fibrosis is the result of persistent necroinflammation in the liver, pro-inflammatory cytokines secreted in response to cell injury have a central role in the pathogenesis of liver fibrosis. We aimed to investigate the association of cytokine gene polymorphism and liver fibrosis among Chinese patients with chronic hepatitis B. METHODS Polymorphisms at interleukin-10 (IL-10-627, -1117), interleukin-1-beta (IL-1beta-511, -31, -3964), interleukin-1 receptor antagonist (IL-1RN), and tumor necrosis factor-alpha (TNF-alpha-308, -238) among Chinese chronic hepatitis B patients were determined. Severe liver fibrosis was defined as Ishak fibrosis score = 4 (of 6). RESULTS Fifty-nine of 273 (22%) patients had severe fibrosis. The distribution of genotypes for IL-10-627 was CC (11%), CA (41%), and AA (48%). The CC genotype at IL-10-627 was protective against severe fibrosis (odds ratio (OR) 0.11; 95% CI 0.014-0.82; P = 0.032). After adjusted for baseline variables, the adjusted OR of CC genotypes at IL-10-627 for severe fibrosis was 0.063 (95% CI 0.06-0.64; P = 0.063). Other gene polymorphisms at IL-1beta, IL-1RN, TNF-alpha, and IL-10 had no significant association with severe fibrosis. Weak linkage disequilibrium was observed between IL-10-627 and IL-10-1117 with linkage disequilibrium coefficient of 0.12 (P < 0.001). The distribution of haplotypes of IL-10-1117 and IL-10-627 was A-A (69%), A-C (26%), and G-C (5%). High and intermediate IL-10 production (A-C and G-C) haplotypes were protective against severe fibrosis (OR 0.62; 95% CI 0.39-0.99; P = 0.046). CONCLUSIONS High production genotype and haplotypes of IL-10 were associated with less severe liver fibrosis in chronic hepatitis B in Chinese.

Abstract
Background Although nucleot(s)ide analogues can effectively suppress hepatitis B virus (HBV) replication, many patients experience relapse of hepatitis after cessation of treatment. We aimed to investigate the efficacy of pegylated interferon α2a (PEG-IFN-α2a) in these difficult-to-treat patients. Methods Chronic hepatitis B patients who have received antiviral drugs for ≥12 months and stopped for ≥6 months were treated by 48-week PEG-IFN-α2a. Virological response was defined as HBV DNA <10,000 copies/ml and hepatitis B e antigen (HBeAg) seroconversion (for HBeAg-positive patients). Results A total of 40 patients, 29 HBeAg-positive and 11 HBeAg-negative, with median log10 HBV DNA 7.3 copies/ml and alanine aminotransferase 110 IU/ml were studied. The last antiviral treatment was given for 92 +61 weeks and stopped for 176 +88 weeks. At the end of treatment, 22 (12 HBeAg-positive and 10 HBeAg-negative; 55%) patients had virological response and 16 (7 HBeAg-positive and 9 HBeAg-negative; 40%) patients had undetectable HBV DNA (<100 copies/ml). At 24 weeks post-treatment, 14 (8 HBeAg-positive and 6 HBeAg-negative; 35%) patients had virological response and 9 (5 HBeAg-positive and 4 HBeAg-negative; 23%) patients had undetectable HBV DNA. Two (5%) patients had lost hepatitis B surface antigen. HBV DNA levels at week 24 best predicted sustained virological response (area under curve 0.76, 95% confidence interval 0.60–0.92, P=0.007). At HBV DNA cutoffs of 3 logs and 5 logs at week 24, the sensitivity/specificity for sustained virological response were 50%/85% and 86%/62%, respectively. Conclusions PEG-IFN-α2a was effective in the treatment of chronic hepatitis B patients who have failed previous antiviral treatment.

Abstract
BACKGROUND AND AIM Symptoms and complications of primary biliary cirrhosis (PBC) have been shown to impair patients' health-related quality of life (HRQOL) in the West. We aimed to measure the HRQOL and to determine the factors associated with worse HRQOL among the Chinese PBC patients in Hong Kong. METHODS Chinese patients with biopsy-proven PBC were compared with an age- and gender-matched control group of patients suffering from uncomplicated hypertension (HT) and chronic hepatitis B (CHB). Their HRQOL was assessed by a Chinese (Hong Kong) version of the 36-item short-form health survey (SF-36). The psychological aspect of patients was assessed by the Hospital Anxiety and Depression Scale (HADS). RESULTS Forty-four PBC patients aged 60 +/- 11 years were identified. PBC patients had more profound impairment in their HRQOL, as evidenced by their significantly lower Physical Component Summary (PCS) scores (39 +/- 11 vs 45 +/- 9 and 45 +/- 11, P = 0.009 and 0.01) and slightly lower Mental Component Summary (MCS) score (47 +/- 12 vs 51 +/- 10 and 48 +/- 11, P = 0.051 and 0.80) as compared with the HT and CHB control groups, respectively. High HADS-depression score was independently associated with lower PCS scores. More severe fatigue and higher HADS-anxiety and HADS-depression scores were independently associated with lower MCS scores. CONCLUSION Chinese PBC patients have significant impairment of the HRQOL. The anxiety and depression status of patients had important contribution to the HRQOL.

Abstract
Evidence-based management guidelines for non-alcoholic fatty liver disease (NAFLD) are lacking in the Asia-Pacific region or elsewhere. This review reports the results of a systematic literature search and expert opinions. The Asia-Pacific Working Party on NAFLD (APWP-NAFLD) has generated practical recommendations on management of NAFLD in this region. NAFLD should be suspected when there are metabolic risk factors and/or characteristic changes on hepatic ultrasonography. Diagnosis by ultrasonography, assessment of liver function and complications, exclusion of other liver diseases and screening for metabolic syndrome comprise initial assessment. Liver biopsy should be considered when there is diagnostic uncertainty, for patients at risk of advanced fibrosis, for those enrolled in clinical trials and at laparoscopy for another purpose. Lifestyle measures such as dietary restrictions and increased physical activity (aerobic exercise) should be encouraged, although the best management strategy to achieve this has yet to be defined. Complications of metabolic syndrome should be screened for regularly. Use of statins to treat hypercholesterolemia is safe and recommended; frequent alanine aminotransferase (ALT) monitoring is not required. Obese patients who do not respond to lifestyle measures should be referred to centers specializing in obesity management; consideration should be given to bariatric surgery or gastric ballooning. The role of pharmacotherapy remains investigational and is not recommended for routine clinical practice. Non-alcoholic fatty liver disease should be recognized as part of the metabolic syndrome and managed in a multidisciplinary approach that addresses liver disease in the context of risk factors for diabetes and premature cardiovascular disease. Lifestyle changes are the first line and mainstay of management.

Abstract
BACKGROUND Non-alcoholic fatty liver disease is prevalent in affluent countries and is strongly associated with metabolic syndrome. AIM To study the prevalence of undiagnosed diabetes and postchallenge hyperglycaemia in Chinese patients with non-alcoholic fatty liver disease. METHODS 73 consecutive patients with biopsy-proven non-alcoholic fatty liver disease and no history of diabetes underwent comprehensive metabolic screening. Diagnosis of diabetes and impaired glucose regulation was based on the 2006 American Diabetes Association criteria. RESULTS The prevalence of undiagnosed diabetes and impaired glucose tolerance in non-alcoholic fatty liver disease patients was 33% and 29%, respectively. Among patients with 2-h plasma glucose above 7.8 mm, 47% had normal fasting glucose (below 5.6 mm). Impaired glucose tolerance was more common in patients with non-alcoholic steatohepatitis than those with simple hepatic steatosis (P = 0.036), and 2-h plasma glucose correlated with fibrosis stage (Spearman coefficient: 0.25, P = 0.046). In a binary logistic regression analysis, high fasting glucose and low high-density lipoprotein cholesterol were independent factors associated with diabetes. Nevertheless, if oral glucose tolerance test was only performed in non-alcoholic fatty liver disease patients with impaired fasting glucose, 20.8% of diabetes cases would be missed. CONCLUSIONS Isolated postchallenge hyperglycaemia is common among Chinese non-alcoholic fatty liver disease patients without history of diabetes. It is associated with histological severe disease, and cannot be accurately predicted by any fasting glucose cut-off.

Abstract
AIMS/HYPOTHESIS We examined the association between chronic hepatitis B virus (HBV) infection and clinical outcomes in a consecutive cohort of Chinese patients with type 2 diabetes. SUBJECTS, MATERIALS AND METHODS Between 1995 and 1999, 2,838 type 2 diabetes patients underwent comprehensive assessments and blood screening for hepatitis B surface antigen (HBsAg). The risk of occurrence of cardiovascular events and end-stage renal disease (defined as need for dialysis, doubling of serum creatinine or serum creatinine > or =500 micromol/l) was compared between HBsAg-positive and HBsAg-negative groups. RESULTS At baseline, HBV-infected patients (n=286, 10.1%) were younger (51.0+/-11.5 vs 53.7+/-12.7 years, p=0.004), had earlier onset of diabetes (51.0+/-11.5 vs 53.7+/-12.7 years, p=0.001) and a higher frequency of retinopathy (28 vs 22%, p=0.03) than non-HBV-infected patients. After a median follow-up of 3.5 years (interquartile range: 1.7-5.9 years) and adjustment of age, glycaemic control and other potential confounding factors, HBV-infected patients were more likely to develop end-stage renal disease than non-HBV infected patients (8.7 vs 6.4%) with a hazard ratio of 4.5 (95% CI 1.1-18.6). The difference in the frequency of cardiovascular endpoints was not statistically significant. CONCLUSIONS In Chinese type 2 diabetes patients, chronic HBV infection was associated with increased risk of end-stage renal disease, and this was independent of other potential confounding factors. Early identification of HBV status and close surveillance of renal function are important in patients with type 2 diabetes who are living in areas where HBV is endemic or who are at risk of chronic HBV infection.
