Abstract
Hepatitis B virus (HBV) infection can cause arthritis, but it is rarely reported. In the current report, we present a case of chronic polyarthritis in a patient with untreated HBV infection. A 63-year-old woman suffering from polyarthritis in her fingers visited our institution. She had experienced exacerbations and remissions of polyarthritis for more than 20 years. She had been diagnosed with rheumatoid arthritis and had been treated with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and nonsteroidal anti-inflammatory drugs by her primary care doctor, but the csDMARDs were discontinued at the request of the patient 10 years before the first visit to our hospital. The blood test showed negative for rheumatoid factor and anticyclic citrullinated peptides antibody but positive for hepatitis B surface antigen. Hepatitis B surface antigen and HBV-Deoxyribo Nucleic Acid (DNA) were increased to 312.6 (IU/ml) and 4.6 (log copies/ml), respectively. Based on the results of abdominal computed tomography and echography, she was diagnosed with liver cirrhosis. Treatment for HBV infection was begun with oral tenofovir at 25 mg/day. The polyarthritis in her fingers gradually disappeared and has not relapsed for 6 months after the initiation of treatment for HBV infection. When polyarthritis is diagnosed, the possibility that chronic HBV infection can be one of the causes of polyarthritis should be considered.

Abstract
BackgroundTo investigate the effect of intermittent interferon therapy mode on the disappearance of hepatitis B surface antigen (HBsAg) in chronic hepatitis B (CHB) patients.MethodsThis is a retrospective cohort study in CHB patients who were suspended from pegylated interferon α (PEG-IFNα) therapy due to a plateau in HBsAg decline during the initial treatment period, and resumed interferon therapy after an interval of 3–6 months. Patients received entecavir or tenofovir during the interval period. Hepatitis B virus (HBV) virological and serological indexes, clinical biochemical indexes, and blood routine tests were performed at the baseline and every 3 months during follow-up of initial interferon treatment. A functional cure was analyzed as a primary outcome.ResultsA total of 304 patients treated with intermittent PEG-IFNα were included in the statistical analysis, including 215 men and 89 women, aged 37.97 ± 8.53 years, and 73 hepatitis B e antigen (HBeAg)-negative and 231 HBeAg positive patients. In total 59 patients (19.41%) achieved HBsAg disappearance through the initial, intermittent, and retreatment of PEG-IFNα treatment, of whom 43 patients (14.14%) achieved HBsAg seroconversion. Early HBsAg response to initial treatment was significantly associated with HBsAg response at 12 and 24 weeks of retreatment. After the intermission period, the incidence of HBsAg disappearance in patients with early HBsAg response in the retreatment period was 43.87%. The baseline HBsAg and 12-week HBsAg response in the retreatment period had higher predictive value than the initial treatment HBsAg response.ConclusionThe initial, intermittent, and retreatment mode of interferon can help to improve the HBsAg disappearance rate in CHB patients.Clinical trial registration[www.ClinicalTrials.gov], identifier [NCT04028856].

Abstract
Aims Induction of a durable viral response is difficult to achieve in patients with chronic hepatitis B (CHB), even from long-term use of a nucleos(t)ide analogue (NA). This study investigated whether switching to peginterferon (PegIFN) alfa-2a after long-term NA therapy induced a durable viral response. Methods Patients with hepatitis B e antigen (HBeAg)-positive CHB who received any NA for at least 72 weeks and had a low level of HBV DNA (≤100 IU/mL) were randomized (1:1) to receive PegIFN alfa-2a (180 μg/week) or NA for 48 weeks. The primary endpoint was change in the hepatitis B surface antigen (HBsAg) titer during antiviral therapy. Results We randomized 149 CHB patients to the two groups. Compared to baseline, the HBsAg levels in both groups were not lower at week 12, but were lower after 24, 36, and 48 weeks (all p<0.001). The maximal HBsAg decline in the PegIFN alfa-2a group was at week 36 (0.50±0.88 log10 IU/mL), and this decline was smaller in the NA group (0.08±0.46 log10 IU/mL). The percentage of patients with HBeAg seroconversion at week 48 was also greater in the PegIFN alfa-2a group (15/75 [20.0%] vs. 5/74 [6.8%], p = 0.018). Multivariable analysis indicated the PegIFN alfa-2a group had a greater change in HBeAg seroconversion at week 48 (p = 0.027). Patients had relatively good tolerance to PegIFN alfa-2a therapy. Conclusions CHB patients who switched to PegIFN alfa-2a for 48 weeks had a significantly lower HBsAg titer and increased HBeAg seroconversion relative to those who remained on NA therapy.

Abstract
Viral hepatitis remains a significant global health problem. All forms of viral hepatitis A through E (A-E) can lead to acute symptomatic infection, while hepatitis B and C can lead to chronic infection associated with significant morbidity and mortality related to progression to cirrhosis, end-stage-liver disease, and liver cancer. Viral hepatitis occurs worldwide, though certain regions are disproportionately affected. We now, remarkably, have highly effective curative regimens for hepatitis C, and safe and tolerable medications to suppress hepatitis B activity, and to prevent liver damage and slow disease progression. We have effective vaccines for hepatitis A and B which provide long-lasting immunity, while improved sanitation and awareness can curb outbreaks of hepatitis A and E. However, more effective and available preventive and curative strategies are needed to achieve global eradication of viral hepatitis. This review provides an overview of the epidemiology, transmission, diagnosis, and clinical features of each viral hepatitis with a primary focus on current and future therapeutic and curative options.

Abstract
The currently available antiviral treatments (Peg-Interferon-α and Nucleos(t)ide Analogues, NA) for chronic hepatitis B (CHB) achieve a functional cure (serum HBsAg and HDV-DNA clearance) of HBV infection in a limited number of patients. Nevertheless, the continuous pharmacological suppression of viral replication by NA halts liver disease progression lowering the risk of HCC development and improving the survival. In the near future, to fully exploit the potential of old and new drugs for HBV treatment a personalized approach to the patients will be required according to an accurate definition of their virologic, immunologic and clinical profile.

Abstract
We examined the association between serum miRNA (-192-5p, -122-3p, -320a and -6126-5p) levels and the efficacy of pegylated interferon (Peg-IFN) monotherapy for chronic hepatitis B (CHB) patients. We enrolled 61 CHB patients treated with Peg-IFNα-2a weekly for 48 weeks, of whom 12 had a virological response (VR) and 49 did not VR (non-VR). A VR was defined as HBV DNA < 2,000 IU/ml, hepatitis B e antigen (HBeAg)-negative, and nucleos(t)ide analogue free at 48 weeks after the end of treatment. The non-VR group showed a significantly higher HBeAg-positivity rate, ALT, HBV DNA, and serum miR-192-5p levels at baseline (P = 0.024, P = 0.020, P = 0.007, P = 0.021, respectively). Serum miR-192-5p levels at 24-weeks after the start of treatment were also significantly higher in the non-VR than the VR group (P = 0.011). Multivariate logistic regression analysis for predicting VR showed that miR-192-5p level at baseline was an independent factor (Odds 4.5, P = 0.041). Serum miR-192-5p levels were significantly correlated with the levels of HBV DNA, hepatitis B core-related antigen, and hepatitis B surface antigen (r = 0.484, 0.384 and 0.759, respectively). The serum miR-192-5p level was useful as a biomarker for the therapeutic efficacy of Peg-IFN in CHB treatment.

Abstract
BACKGROUND Recent studies report incongruent finds regarding the addition of pegylated interferon -alpha (Peg- IFNα) to nucleos(t)ide analogues. This study was designed to compare the efficacy of Peg- IFNα and tenofovir disoproxil fumarate (TDF) combination therapy with each of the treatments separately. METHODS In this open-label, randomized clinical trial, treatment-naive hepatitis B e antigen (HBeAg)-negative patients were randomly assigned to three treatment groups: Group A: Peg- IFNα (180 mcg/week) with TDF (300 mg/day); Group B: TDF (300 mg/day); and Group C: Peg- IFNα (180 mcg/week). The intervention spanned 48 weeks and patients were followed up every 12 weeks. The primary end-point was HBV DNA load <20 IU/mL. RESULTS Groups A, B and C each comprised of 22, 23 and 22 patients, respectively. The number of patients with HBV DNA suppression in group A was significantly higher compared to groups B and C (P = 0.034). No significant difference was observed in the normalization trends of serum ALT levels between the three groups (P = 0.082). At week 48, combination therapy was significantly more effective in suppressing HBV DNA concentration to below the level of detection than TDF monotherapy (OR = 2.1, 95%CI: 1.18-4.15; P = 0.034). Furthermore, a comparison between monotherapy arms revealed that both interventions had similar effects on the overall outcome (OR = 1.24, 95%CI: 1.02-5.8; P = 0.062). CONCLUSION A Peg- IFNα and TDF combination therapy resulted in improved virologic response and was safe in HBeAg negative patients. Monotherapy with Peg-IFNα or TDF procured limited benefits in comparison. TRIAL REGISTRATION This study was registered in the Iranian Registry of Clinical Trials (IRCT20181113041635N1).

Abstract
Identification and screening of patients with hepatitis B virus (HBV) or hepatitis C virus (HCV) is important to prevent liver cancer. Comprehensive antiviral treatments should follow three sequential steps: Hepatitis screening (step 1; examination of HB surface antigen and HCV antibody), medical examination (step 2; examination of HBV-DNA and/or HCV-RNA and performance of abdominal ultrasonography) and antiviral treatment (step 3). Patients who underwent these three steps were studied to determine effective information sources (factors) for raising awareness of comprehensive treatments. A total of 182 patients from 11 medical institutions were who were undergoing antiviral treatment were investigated. The number of patients who accessed each of the 18 information sources in each of the three steps and the percentage of these information sources that directly influenced the participants to make treatment-related decisions were calculated. 'Recommendation from a primary care physician' was the most common information source (64.3, 77.5, and 75.8% at steps 1, 2, and 3, respectively). 'Recommendation from a public health nurse (PHN),' 'recommendation from friends or family,' and 'recommendation from work colleagues' were the next most common human factors (3.3-19.8%). 'Recommendation from a primary care physician' had the greatest influence (76.9, 73.0, and 77.5% at steps 1, 2, and 3, respectively). 'Recommendation from a PHN' (50.0, 26.3 and 64.3%), 'recommendations from friends and family' (58.3, 38.9 and 58.3%), and 'recommendations from work colleagues' (33.3, 33.3 and 42.9%) were highly influential factors. Media such as TV commercial messages and programs also had high recognition, but were not directly influential. The findings of the present study indicated that recommendations from primary care physicians, friends, family and work colleagues influenced patients' decision-making regarding hepatitis screening, examination and treatment.

Abstract
Hepatitis B virus (HBV) is a DNA virus, belonging to the Hepadnaviridae family. It is a partially double-stranded DNA virus with a small viral genome (3.2 kb). Chronic HBV infection remains a global public health problem. If left untreated, chronic HBV infection can progress to end-stage liver disease, such as liver cirrhosis and hepatocellular carcinoma (HCC). In recent years, tremendous advances in the field of HBV basic and clinical research have been achieved, ranging from the HBV biological characteristics, immunopathogenesis, and animal models to the development of new therapeutic strategies and new drugs against HBV. In this overview, we begin with a brief history of HBV discovery and treatment milestones. We then briefly summarize the HBV research advances, which will be detailed in the following chapters.

Abstract
Background: Until now, various types of combined therapy with nucleotide analogs and pegylated interferon (Peg-INF) in patients with hepatitis B patients have been tried. However, studies regarding the benefits of de novo combination, late-add on, and sequential treatment are very limited. The objective of the current study was to identify the efficacy of sequential treatment of Peg-INF after short-term antiviral treatment. Methods: Between June 2010 and June 2015, hepatitis B e antigen (HBeAg)-positive patients (n = 162) received Peg-IFN for 48 weeks (mono-treatment group, n = 81) and entecavir (ETV) for 12 weeks with a 48-week course of Peg-IFN starting at week 5 of ETV therapy (sequential treatment group, n = 81). The primary endpoint was HBeAg seroconversion at the end of follow-up period after the 24-week treatment. The primary endpoint was analyzed using Chi-square test, Fisher's exact test, and regression analysis. Results: HBeAg seroconversion rate (18.2% vs. 18.2%, t = 0.03, P = 1.000) and seroclearance rate (19.7% vs. 19.7%, t = 0.03, P = 1.000) were same in both mono-treatment and sequential treatment groups. The rate of alanine aminotransferase (ALT) normalization (45.5% vs. 54.5%, t = 1.12, P = 0.296) and serum hepatitis B virus (HBV)-DNA <2000 U/L (28.8% vs. 28.8%, t = 0.10, P = 1.000) was not different in sequential and mono-treatment groups at 24 weeks of Peg-INF. Viral response rate (HBeAg seroconversion and serum HBV-DNA <2000 U/L) was not different in the two groups (12.1% vs. 16.7%, t = 1.83, P = 0.457). Baseline HBV-DNA level (7 log10U/ml vs. 7.5 log10U/ml, t = 1.70, P = 0.019) and hepatitis B surface antigen titer (3.6 log10U/ml vs. 4.0 log10U/ml, t = 2.19, P = 0.020) were lower and predictors of responder in mono-treatment and sequential treatment groups, respectively. Conclusions: The current study shows no differences in HBeAg seroconversion rate, ALT normalization, and HBV-DNA levels between mono-therapy and sequential therapy regimens. Trial Registration: ClinicalTrials.gov, NCT01220596; https://clinicaltrials.gov/ct2/show/NCT01220596?term=NCT01220596&rank=1.

Abstract
The experts of Taiwan Association for the Study of Liver (TASL) have actively participated and led the guidelines on hepatitis B virus (HBV) management by Asian Pacific Association for the Study of Liver (APASL) which is the first international association for the study of liver to publish the statement on HBV management before. However, there are more and more new data on the natural history and treatment of HBV infection in the past decade. These include new application of an old biomarker (quantitative HBsAg), clinical significance of HBV genotype and naturally occurring mutations, the role of non-invasive examination in evaluating severity of hepatic fibrosis, clinical significance of outcome calculators, new drug or new combination strategies towards more effective therapy and organ transplantation including liver and non-liver transplantation. It is time to publish the guidelines on HBV management of Taiwan. Hence, TASL have conducted an expert meeting to review, to discuss and to debate the relevant literatures, followed by draft the manuscript of HBV management guidelines and recommendations. The guidelines include general management, indications for fibrosis assessment, time to start or stop drug therapy, choice of drug to initiate therapy, when and how to monitor the patients during and after stopping drug therapy. Recommendations on the therapy of patients in special circumstances, including women in childbearing age, patients with antiviral drug resistance, concurrent viral infection, hepatic decompensation, patient receiving immune suppression or chemotherapy and patients in the setting of liver transplantation and hepatocellular carcinoma, are also included.

Higher efficacy of pegylated interferon-α2b add-on therapy in hepatitis B envelope antigen-positive chronic hepatitis B patients on tenofovir monotherapy. Hepatol Res 2018; 48:451-458. [PMID: 29314573 DOI: 10.1111/hepr.13049] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2017] [Revised: 12/04/2017] [Accepted: 12/26/2017] [Indexed: 01/08/2023]
Abstract
AIM Monotherapy with pegylated interferon-α (Peg-IFNα) or the nucleos(t)ide analogs (NA) currently approved for treating chronic hepatitis B (CHB) has limited efficacy. Studies on the combination of Peg-IFNα/NA have shown conflicting results. We investigated whether sequentially adding on Peg-IFNα to tenofovir enhances serological response rates. METHODS Treatment-naïve, hepatitis B envelope antigen (HBeAg)-positive CHB patients with moderately elevated alanine aminotransferase (ALT; 48-200 IU/mL) were started on tenofovir (300 mg/day) and enrolled at week 12 in a 1:1 ratio to either receive Peg-IFNα2b add-on (1.5 μg/kg/week) from week 12 to 36 (n = 53) or continue tenofovir monotherapy (n = 53). Both treatment arms received tenofovir consolidation therapy until week 72. The primary end-point was HBeAg loss at week 72. RESULTS At week 72, the rate of HBeAg loss was higher in the Peg-IFNα2b add-on group (35.8%) compared to the tenofovir monotherapy group (17%) (P = 0.028; odds ratio, 2.73, 95% confidence interval, 1.09-6.79), and considerably higher in patients with a baseline hepatitis B virus (HBV)-DNA level >6 log IU/mL (32.6% vs 11.4%; P = 0.021). Rates of HBV-DNA loss (77.4% vs 71.7%; P = 0.51), ALT normalization (62.3% vs 52.8%; P = 0.32), and sustained virologic response (20.8% vs 11.3%; P = 0.18) at week 72 were comparable between the two groups. Significantly more patients in the add-on group had >3 log HBV-DNA reduction at week 36 (92.5% vs 66%; P = 0.001). Four patients treated with Peg-IFNα2b add-on achieved hepatitis B surface antigen (HBsAg) loss compared with one patient receiving tenofovir monotherapy. Decline of HBV-DNA of >2 log at week 4 led to higher HBeAg loss at week 72, independent of treatment arm. No patient had treatment-related adverse effects requiring treatment discontinuation. CONCLUSIONS Twenty-four weeks of Peg-IFNα2b as an add-on sequential regimen to tenofovir is safe and resulted in greater loss of HBeAg and HBsAg compared to tenofovir monotherapy in selected HBeAg-positive patients. Viral load reduction followed by immune modulation is a potentially useful approach.

Abstract
The treatment of chronic hepatitis B (CHB) patients is based on monotherapy with pegylated-interferon (Peg-IFN) or with one of the three most potent nucleot(s)ide analogues (NUCs) with the best resistance profiles, i.e. entecavir (ETV), tenofovir disoproxil fumarate (TDF) and tenofovir alafenamide (TAF). Long-term NUCs treatment can achieve virological suppression in almost all patients. However, this requires lifelong therapy, is costly and the rate of hepatitis B surface antigen (HBsAg) seroclearance is low. A one-year course of Peg-IFN has the advantage of providing immune-mediated control of the hepatitis B virus (HBV) infection, the possibility of achieving a sustained off-treatment response in nearly 30% of the patients and ultimately, HBsAg loss in approximately 30%-50% of the latter patients during long-term off treatment follow-up. However, the major limitations to the extensive use of this treatment are the need for parenteral therapy and clinical and laboratory monitoring, the side-effects profile and contraindications in certain patients and the limited effectiveness in a large proportion of patients. Nevertheless, the cost-effectiveness of Peg-IFN can be significantly increased by careful patient selection based upon baseline alanine aminotransferase (ALT), HBV DNA levels, viral genotype, host genetic variants and especially by applying early on-treatment stopping rules based upon HBsAg kinetics. Recently, because of the different mechanisms of action of Peg-IFN and NUCs, the strategy of "adding-on" or "switching to" Peg-IFN in patients being treated with NUCs to accelerate the decline in HBsAg and enhance HBsAg seroclearance rates, has provided interesting results.

Abstract
Chronic hepatitis B infection (CHB) causes up to 1.0 million deaths annually. Currently, more than 90% of CHB patients worldwide are receiving indefinite nucleos(t)ide analogue (NA) therapy. New strategies for optimizing hepatitis B surface antigen (HBsAg) loss are required for NA-treated patients as the majority are unable to achieve HBsAg loss and may require lifelong therapy. In hepatitis B e antigen (HBeAg)-positive patients, switching from NAs to finite peginterferon (PegIFN) therapy can double HBeAg seroconversion rates. One in five patients who switch to PegIFN can achieve HBsAg loss, whereas patients who continue NA therapy typically do not. In HBeAg-negative NA-treated patients, add-on PegIFN therapy achieves higher, albeit modest, HBsAg loss rates compared with continued NA monotherapy and offers the opportunity for NA-treated patients to achieve the inactive carrier state. In the absence of curative therapies, PegIFN represents a valuable, finite option for NA-treated patients who would otherwise require potentially lifelong therapy.

Abstract
Evidence of a role of vitamin D in the immune system is increasing. Low serum vitamin D is associated with increased hepatitis B virus replication. Genome-wide association study (GWAS) data has revealed a number of the single nucleotide polymorphisms (SNPs) within the vitamin D synthetic pathway that affect vitamin D functions. We aimed to determine the association between SNPs in the vitamin D gene cascade and response to pegylated interferon (PegIFN) therapy in hepatitis B e-antigen (HBeAg)-positive patients. One hundred and eleven patients treated for 48 weeks with PegIFN-alfa 2a at 13 hospitals were retrospectively evaluated. Thirteen SNPs derived from vitamin D cascade-related genes, including DHCR7 (rs12785878), CYP27B1 (rs10877012), CYP2R1 (rs2060793, rs12794714), GC (rs4588, rs7041, rs222020, rs2282679), and VDR (FokI, BsmI, Tru9I, ApaI, TaqI), were genotyped. Thirty-one patients (27.9%) seroconverted to HBeAg after 24 weeks of treatment. Multivariate analysis found pretreatment qHBsAg <10,000 IU/mL (OR = 7.73, 95% CI: 2.36-25.31, P = 0.001), CYP2R1 rs12794714 TT genotype (OR = 4.16, 95% CI: 1.07-16.25, P = 0.04), and baseline ALT >2 times the upper limit of normal (OR = 3.83, 95% CI: 1.31-11.22, P = 0.014) predicted sustained HBeAg seroconversion after completion of PegIFN treatment. HBV DNA during study period tended to be lower with the rs12794714 CYP2R1 TT than the non-TT genotype. The rs12794714 CYP2R1 polymorphism may be a useful pretreatment factor predictive of sustained HBeAg seroconversion after PegIFN therapy. This study provides evidence that not only vitamin D level but also genetic variation of CYP2R1 in the vitamin D cascade influences host immune response in chronic HBV infection.

Abstract
BACKGROUND AND AIM Clinically applicable models to predict hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) response to peginterferon (PEG-IFN) are scarce. This study aimed to develop simple scoring systems, based on multiple parameters, for predicting sustained HBeAg seroconversion to PEG-IFN. METHODS Eighty-five treatment-naïve patients with HBeAg-positive CHB underwent 52-week PEG-IFN treatment and 24-week follow-up. Logistic regression analysis assessed parameters at baseline and weeks 12, 24, and 52 to predict HBeAg seroconversion at week 24 off-treatment. The best three predictors at each time point were included in prediction models of PEG-IFN therapy efficacy. RESULTS The three most meaningful predictors were alanine aminotransferase (ALT) > 5 × ULN, HBeAg ≤ 500 S/CO, and antibody to hepatitis B core antigen (anti-HBc) > 10.7 S/CO at baseline; HBeAg ≤ 20 S/CO, anti-HBc > 11.7 S/CO, and HBeAg decline > 1 log10 S/CO at week 12; ALT > 2 × ULN, HBeAg ≤ 15 S/CO, and anti-HBc > 10.4 S/CO at week 24; HBeAg ≤ 5 S/CO, anti-HBc > 11.1 S/CO, and hepatitis B virus DNA decline > 2 log10 copies/mL at week 52. Parameters meeting optimal cutoff thresholds were scored 1 or otherwise scored 0. For total scores of 0 versus 3 at baseline and weeks 12, 24, and 52, response rates were 6.3%, 12.5%, 0%, and 0% versus 90.0%, 83.3%, 76.9%, and 86.4%, respectively. CONCLUSIONS We successfully established prediction models for PEG-IFN response in HBeAg-positive CHB.

Abstract
Chronic hepatitis B virus (HBV) infection has a significant public health impact. There are currently 7 approved therapies for chronic HBV, including standard and pegylated interferon (IFN)-α, and 5 nucleos(t)ide analogs (NUCs). IFN offers benefits over NUCs, including a finite duration of therapy and a higher rate of clearance of hepatitis Be antigen and surface antigen. These benefits need to be weighed against the potential adverse effects of IFN therapy. Some patients should not receive IFN because of advanced liver disease or comorbidities. This article reviews the mechanisms of action, efficacy, and clinical use of IFN therapy for HBV infection.

BACKGROUND AND AIMS Peginterferon has demonstrated effectiveness in clinical trials in patients with chronic hepatitis B (CHB). However, its efficacy in real-life settings remains unclear. We investigated the efficacy of peginterferon for CHB and validated the performance of previously identified response predictors in clinical practice. METHODS We analyzed prospectively collected data from a Thai nationwide cohort of CHB patients treated with peginterferon alfa-2a (180 µg/week, 48 weeks). RESULTS Among a total of 233 patients, mostly with genotype B or C, sustained response was observed in 23% of 135 hepatitis B e antigen (HBeAg)-positive patients (HBeAg seroconversion with hepatitis B virus [HBV] DNA < 2000 IU/mL) and 42% of 98 HBeAg-negative patients (HBV DNA < 2000 IU/mL with aminotransferase normalization) at 24 weeks after treatment. Age, sex, presence of cirrhosis, genotype, and pretreatment levels of aminotransferase, HBV DNA, and hepatitis B surface antigen (HBsAg) were not identified as significant predictors of sustained response. In HBeAg-positive patients, HBsAg > 20 000 IU/mL at week 12 provided a good stopping rule, with a negative predictive value of 96%. In HBeAg-negative patients, the performance of 12-week stopping rules of no decline in HBsAg with a < 2log10 decline in HBV DNA and a < 10% log10 decline in HBsAg showed modest negative predictive values of 80% and 66%, respectively, for achieving sustained response. CONCLUSION Outcomes in CHB patients treated with peginterferon in a clinical setting are similar to those demonstrated in clinical trials. Application of the early stopping rule based on HBsAg quantification may allow individualization of therapy, particularly in HBeAg-positive patients.

A Meta-Analysis of the Efficacy of Interferon Monotherapy or Combined with Different Nucleos(t)ide Analogues for Chronic Hepatitis B. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2016; 13:ijerph13070730. [PMID: 27455288 PMCID: PMC4962271 DOI: 10.3390/ijerph13070730] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/10/2016] [Revised: 06/20/2016] [Accepted: 07/12/2016] [Indexed: 12/16/2022]
Abstract
Background: The aim of the present study was to compare the efficacy of interferon (IFN) with or without different nucleos(t)ide analogues (NAs). Methods: The PubMed, Wan Fang and CNKI databases were searched to identify relevant trials up to May 2015. Meta-analysis was performed with Review Manager 5.0. The stability and reliability were evaluated by publication bias tests. Results: Fifty-six studies fulfilled the criteria for the meta-analysis. Compared with IFN monotherapy, combination therapy were superior in HBV DNA undetectable rate (Risk Ratio (RR) = 1.55, 95% confidence interval (CI): 1.44–1.66, p < 0.00001), HBeAg and HBsAg loss rate (RR = 1.38, 95% CI: 1.22–1.56, p < 0.00001; RR = 1.69, 95% CI: 1.03–2.78, p = 0.04, respectively) at the end of week 48 treatment. Sub-analysis showed the RRs of virological response for entecavir (ETV), adefovir (ADV), and lamivudine (LAM) were 1.64, 1.61 and 1.52, respectively; RRs of HBeAg loss rate were 1.34, 1.71 and 1.34, respectively. However, at the end of follow-up, IFN plus NAs therapy was better than IFN monotherapy only in terms of HBV DNA undetectable rate (p = 0.0007). Conclusions: Combination therapy was better than IFN monotherapy in virological and serological responses at the end of treatment. After follow-up, only HBV DNA undetectable rate was superior for combination therapy.

Abstract
Hepatitis B virus (HBV) is characterized by a high genetic heterogeneity since it replicates via a reverse transcriptase that lacks proofreading ability. Up to now, ten genotypes (A-J) have been described, with genotype A and D being ubiquitous but most prevalent in Europe and Africa, genotype B and C being confined to Asia and Oceania. Infections with other genotypes such as E, F, G and H are also occasionally observed in Asia. Genotype I is rare and can be found in Laos, Vietnam, India and China, whereas genotype J has been described in Japan and Ryukyu. Novel variants generated by recombination and co-infection with other genotypes have gradually gotten worldwide attention and may be correlated with certain clinical features. There are substantial differences in HBV infection regarding prevalence, clinical manifestation, disease progression and response to antiviral therapy. Due to the complex interplay among viral, host and environmental factors, the relationship between HBV genotypes and clinical profiles remains incompletely revealed. In general, genotype A is associated with better response to interferon therapy; genotype C, and to lesser extent B, usually represent a risk factor for perinatal infection and are associated with advanced liver diseases such as cirrhosis and hepatocellular carcinoma; genotype D may be linked with poor response to interferon therapy. Future studies with better design and larger sample size are warranted to further clarify the controversial issues and guide the day-to-day clinical practice.

Abstract
BACKGROUND In the OSST study, hepatitis B e antigen (HBeAg)-positive chronic hepatitis B patients who switched from long-term entecavir (ETV) therapy to pegylated interferon-α2a (PEG-IFN-α2a; 40 kDa) achieved higher rates of HBeAg seroconversion and hepatitis B surface antigen (HBsAg) loss than those who continued ETV. Herein we report the sustainability of serological responses during 1 year of untreated follow-up in patients who switched from ETV to PEG-IFN-α2a therapy. METHODS A total of 62 patients who completed 48 weeks of PEG-IFN-α2a therapy were followed-up for 48 weeks off treatment. Primary end points were HBeAg seroconversion and maintenance of HBeAg seroconversion at 48 weeks post-treatment. Secondary end points included HBsAg loss, HBV DNA <1,000 copies/ml and alanine aminotransferase normalization (<1× upper limit of normal). RESULTS The HBeAg seroconversion rate increased from 17.7% (11/62) at the end of treatment to 38.7% (24/62) 1 year post-treatment. Sustained HBeAg seroconversion was achieved by 63.6% (7/11) patients with end-of-treatment responses, while late HBeAg seroconversion was achieved by 33.3% (17/51) of patients who did not have end-of-treatment responses. Sustained HBsAg loss was documented in 6 of 7 patients, and sustained HBV DNA suppression was achieved in 60% (27/45) of patients with an end-of-treatment response. CONCLUSIONS In patients who do not achieve HBeAg seroconversion during long-term ETV therapy, switching to finite treatment with PEG-IFN-α2a produces HBeAg seroconversion in a substantial proportion of patients at end of treatment and during 1 year of follow-up. Moreover, HBeAg seroconversion and HBsAg loss are sustained in most patients during 1 year of untreated follow-up.

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
Chronic liver disease and liver cancer associated with chronic hepatitis B (CHB) are leading causes of death among adults in China. Although newborn hepatitis B immunization has successfully reduced the prevalence of CHB in children, about 100 million Chinese adults remain chronically infected. If left unmanaged, 15–25% will die from liver cancer or liver cirrhosis. Antiviral treatment is not necessary for all patients with CHB, but when it is indicated, good response to treatment would prevent disease progression and reduce disease mortality and morbidity, and costly complications. The aim of this study is to analyze the cost-effectiveness of generic and brand antiviral drugs for CHB treatment in China, and assessing various thresholds at which a highly potent, low resistance antiviral drug would be cost-saving and/or cost-effective to introduce in a national treatment program. We developed a Markov simulation model of disease progression using effectiveness and cost data from the medical literature. We measured life-time costs, quality adjusted life years (QALYs), incremental cost-effectiveness ratios (ICERs), and clinical outcomes. The no treatment strategy incurred the highest health care costs ($12,932-$25,293) per patient, and the worst health outcomes, compared to the antiviral treatment strategies. Monotherapy with either entecavir or tenofovir yielded the most QALYs (14.10–19.02) for both HBeAg-positive and negative patients, with or without cirrhosis. Threshold analysis showed entercavir or tenofovir treatment would be cost saving if the drug price is $32–75 (195–460 RMB) per month, highly cost-effective at $62–110 (379–670 RMB) per month and cost-effective at $63–120 (384–734 RMB) per month. This study can support policy decisions regarding the implementation of a national health program for chronic hepatitis B treatment in China at the population level.

A Better Antiviral Efficacy Found in Nucleos(t)ide Analog (NA) Combinations with Interferon Therapy than NA Monotherapy for HBeAg Positive Chronic Hepatitis B: A Meta-Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2015; 12:10039-55. [PMID: 26308024 PMCID: PMC4555327 DOI: 10.3390/ijerph120810039] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/01/2015] [Revised: 08/09/2015] [Accepted: 08/13/2015] [Indexed: 01/05/2023]
Abstract
BACKGROUND The clinical efficacy of nucleos(t)ide analogues (NAs) combined with interferon (IFN) therapy vs. NAs monotherapy for chronic hepatitis B (CHB) remains inconclusive. The aim of this meta-analysis was to determine whether the NAs plus IFN regimen offers synergistic efficacy that justifies the cost and burden of such a combination therapy in CHB patients. METHODS Related publications covering the period of 1966 to July 2014 were identified through searching MEDLINE, EMBASE, Cochrane library, Chinese Biomedical Literature Database, WANFANG, and CNKI database. A total of 17 studies were enrolled, including 6 in English and 11 in Chinese. Then, we established a final list of studies for the meta-analysis by systematically grading the quality and eligibility of the identified individual studies. We used hepatitis B antigen (HBeAg) loss, HBV-DNA undetectable rate, HBeAg seroconversion, hepatitis B surface antigen (HBsAg) loss, HBsAg seroconversion, and histological score at the end of treatment for efficacy evaluation. A quantitative meta-analysis (Review Manager, Version 5.1.0) was performed to assess the differences between NAs and IFN combination therapy and NAs monotherapy. RESULTS Our analysis demonstrated that HBeAg loss (RR = 1.73, 95% CI = 1.32-2.26, p < 0.001), HBV-DNA undetectable rate (RR = 1.58, 95% CI = 1.22-2.04, p < 0.001), HBeAg seroconversion (RR = 1.68, 95% CI = 1.36-2.07, p < 0.001), and HBsAg loss (RR = 2.51, 95% CI = 1.32-4.75, p < 0.001) in the combination therapy group were significantly higher than those in the monotherapy group. However, there were no significant differences in HBsAg seroconversion (RR = 4.25, 95% CI = 0.62-29.13, p = 0.14), sustained virological response rates, and biochemical response rates observed between the two groups. The results showed that the combination therapy group had more improved HBV histology than the NAs monotherapy group (RR = 1.14, 95% CI = 0.93-1.39, p = 0.22). CONCLUSIONS NAs and IFN or Peg-IFN combination therapy had a better efficacy in terms of HBeAg loss, HBV-DNA undetectable rate, HBeAg seroconversion, and HBsAg loss, compared to the NA monotherapy group at the end of treatment; however, there was no significant difference in HBsAg seroconversion between the two regimens.

Abstract
Current agents for the treatment of chronic hepatitis B (CHB) can be classified into interferon-α (standard or pegylated) (IFN) and nucleos(t)ide analogues (NAs). IFN therapy has the advantage of a finite duration (48 weeks) with a chance for durable sustained off-treatment response in HBeAg positive CHB patients. However, these benefits are limited to approximately 30% of HBeAg positive patients, while parenteral administration and potential side effects are common patient concerns. Thus, patients who can benefit from IFN therapy must be carefully selected and monitored. Recently, stopping rules for IFN non-responders were developed based on 12-week HBsAg levels. NAs are currently used in most CHB patients. They are administered in one tablet daily and can be used in all patients with excellent tolerability and a good safety profile. The current first-line options, entecavir (ETV) and tenofovir (TDF), are highly potent with a minimal risk of resistance during long-term monotherapy. Prolongation of entecavir or tenofovir maintains the initially high virological remission rates in adherent HBeAg positive patients and modifies the long-term outcomes. The need for a long-term, perhaps indefinite, treatment duration is the main limitation of ETV or TDF, which may sometimes be safely discontinued in HBeAg positive patients who achieve stable HBeAg seroconversion. Since there will always be safety concerns and family planning issues with long-term therapy, NAs should be used carefully particularly in young HBeAg positive patients with minimal-mild liver disease.

Abstract
BACKGROUND Hepatic flares (HF), which reflect hepatitis B virus (HBV)-related immune reconstitution inflammatory syndrome (IRIS), frequently occur in patients with HBV and human immunodeficiency virus (HIV) coinfection after the start of antiretoroviral therapy (ART). The rate of hepatitis B envelope antigen (HBeAg) and hepatitis B surface antigen (HBsAg) loss is higher for patients with HF after the initiation of ART. METHODS We retrospectively examined the kinetics of the HBsAg and HBeAg levels of six HBV/HIV coinfected patients after the commencement of ART that included tenofovir. All were male and HBeAg positive. RESULTS Three patients developed HF after the initiation of ART. All subsequently lost HBeAg and one of them lost HBsAg after HF. None who did not experience HF lost HBeAg. The HBsAg and HBeAg levels remarkably decreased when HF occurred, but the decline of HBsAg was very slow in the periods before and after HF. The median decline of the HBsAg level at 48 weeks was 2.20 Log IU/mL for patients with HF, but only 1.00 Log IU/ml for patients without HF. Little decline was seen for either group in the median decline of the HBsAg level from 48 weeks to 96 weeks, 0.28 Log IU/mL in the HF group and 0.06 Log IU/mL in the non-HF group. CONCLUSION The immune reconstitution of a HBV/HIV coinfected patient plays an important role in the clearance of HBV. If HBsAg and HBeAg levels decrease rapidly when HF occurs, the hepatic flare would be due to HBV-related IRIS.

Abstract
AIM: To describe a population of outpatients in China infected by hepatitis B virus (HBV) and/or hepatitis C virus (HCV), and assess their current management status.
METHODS: A multicenter, cross-sectional study of HBV- and/or HCV-infected patients was conducted from August to November, 2011 in western China. Patients ≥ 18 years of age with HBV and/or HCV infections who visited outpatient departments at 10 hospitals were evaluated, whether treated or not. Data were collected on the day of visit from medical records and patient interviews.
RESULTS: A total 4010 outpatients were analyzed, including 2562 HBV-infected and 1406 HCV-infected and 42 HBV/HCV co-infected patients. The median duration of documented infection was 7.5 years in HBV-infected and 1.8 years in HCV-infected patients. Cirrhosis was the most frequent hepatic complication (12.2%), appearing in one-third of patients within 3 years prior to or at diagnosis. The HCV genotype was determined in only 10% of HCV-infected patients. Biopsy data were only available for 54 patients (1.3%). Antiviral medications had been received by 58.2% of patients with HBV infection and 66.6% with HCV infection. Nucleos(t)ide analogs were the major antiviral medications prescribed for HBV-infected patients (most commonly adefovir dipivoxil and lamivudine). Ribavirin + pegylated interferon was prescribed for two-thirds of HCV-infected patients. In the previous 12 mo, around one-fifth patients had been hospitalized due to HBV or HCV infection.
CONCLUSION: This observational, real-life study has identified some gaps between clinical practice and guideline recommendations in China. To achieve better health outcomes, several improvements, such as disease monitoring and optimizing antiviral regimens, should be made to improve disease management.

Abstract
Chronic infection with hepatitis B virus (HBV) leads to the development of hepatocellular carcinoma and/or chronic liver failure. Despite extensive research, the immunopathogenesis is not completely understood. Viral persistence and clinical outcomes following HBV infection depend on viral factors and host factors; including genetic factors that determine a host’s immune mechanisms. The primary goal of chronic hepatitis B (CHB) treatment is to eradicate HBV or to at least maintain suppression of HBV replication. Despite recent advances in anti-viral agents for chronic HBV infection, complete eradication of the virus has been difficult to achieve. Agents for the treatment of CHB are divided mainly into two groups: immunomodulating agents and antiviral nucleos(t)ide analogues (NAs). Although NAs are safe, effective and easily administered orally, their long-term use poses the risk of drug resistance. Currently, international evidence-based guidelines have been developed to support physicians in managing CHB patients. However, treatment of patients with drug resistance is still challenging, as only a few classes of anti-HBV drugs are available and cross-resistance between drugs can occur. In addition, as the currently available genotypic test for detection of drug resistance still has limitations in identifying the different substitutions present in the same viral genome, the development of a new virologic test to overcome this limitation is necessary. Among the predictive factors associated with response to pegylated interferon (PEG-IFN) therapy, hepatitis B surface antigen quantification is considered to be a surrogate marker for monitoring response to PEG-IFN. Current practice guidelines stress the importance of profound and durable HBV viral suppression in the treatment of CHB patients. To this end, it is essential to choose a potent antiviral drug with a low risk of resistance for initial treatment of CHB to achieve sustained virological response. This review highlights recent advances in the understanding of the immunopathogenesis of HBV and currently available and developing treatment strategies against HBV infection.

Abstract
BACKGROUND & AIMS Durable post-treatment response is uncommon in chronic hepatitis B (CHB) patients on nucleos(t)ide analogue therapy. Response, response predictors and safety were assessed in patients who switched from long-term entecavir (ETV) to peginterferon alfa-2a. METHODS Hepatitis B e antigen (HBeAg)-positive CHB patients who had received ETV for 9-36 months, with HBeAg <100 PEIU/ml and HBV DNA ⩽1000 copies/ml, were randomised 1:1 to receive peginterferon alfa-2a 180 μg/week or ETV 0.5mg/day for 48 weeks. The primary endpoint was HBeAg seroconversion at week 48 (ClinicalTrials.gov: NCT00940485). RESULTS 200 patients were randomised; 197 received ⩾1 study drug dose. Five patients who were anti-HBe-positive at baseline were excluded from the modified intention-to-treat population (peginterferon alfa-2a, n = 94; ETV, n = 98). Patients who switched to peginterferon alfa-2a achieved higher week 48 HBeAg seroconversion rates vs. those who continued ETV (14.9% vs. 6.1%; p = 0.0467). Only patients receiving peginterferon alfa-2a achieved HBsAg loss (8.5%). Among peginterferon alfa-2a-treated patients with HBeAg loss and HBsAg <1500 IU/ml at randomisation, 33.3% and 22.2% achieved HBeAg seroconversion and HBsAg loss, respectively. Early on-treatment HBsAg decline predicted response at week 48; highest rates were observed in patients with week 12 HBsAg <200 IU/ml (HBeAg seroconversion, 66.7%; HBsAg loss, 77.8%). Alanine aminotransferase elevations were not associated with viral rebound (n = 38). Peginterferon alfa-2a was well-tolerated. CONCLUSIONS For patients who achieve virological suppression with ETV, switching to a finite course of peginterferon alfa-2a significantly increases rates of HBeAg seroconversion and HBsAg loss. A response-guided approach may identify patients with the greatest chance of success.

Abstract
AIM: To analyze the curative effect of allogeneic dendritic cells-cytokine induced killer (DCs-CIK) in hepatitis B e antigen (HBeAg) positive patients with chronic hepatitis B.
METHODS: From October 2011 to April 2013, the chronic hepatitis B patients whose hepatitis B virus DNA became negative and HBeAg was positive persistently after treatment with pegylated interferon combined with entecavir at our department for 1 year were divided into two groups: A and B. Group A (n = 29) was treated with the original antiviral treatment combined with DCs-CIK for 96 wk, while group B (n = 32) was still treated with pegylated interferon combined with entecavir for 96 wk and did not receive DCs-CIK. The efficacy was compared between the two groups.
RESULTS: After 6 cycles of treatment, the negative conversion rates of hepatitis B surface antigen (HBsAg) and HBeAg in group A were 11/29 (37.9%) and 17/29 (58.6%), respectively. The disappearance rates of HBsAg and HBeAg were 5/29 (17.2%) and 15/29 (51.7%), respectively. In group B, the negative conversion rates of HBsAg and HBeAg were 3/32 (9.3%) and 10/32 (31.3%), respectively; and the disappearance rates of HBsAg and HBeAg were 2/32 (6.2%) and 9/32 (28.1%), respectively. The negative conversion rates and disappearance rates of HBsAg and HBeAg were significantly higher in group A than in group B (P < 0.05).
CONCLUSION: TCs-CIK combined with pegylated interferon and entecavir can achieve a better curative effect than pegylated interferon and entecavir in HBeAg positive chronic hepatitis B patients.

Abstract
There had been remarkable development in nucleos(t)ide analogues (NAs) and evolution in treatment strategies in last 15 years. Currently, there are five NAs available for chronic hepatitis B treatment, namely lamivudine, telbivudine and entecavir (nucleoside analogues), adefovir dipivoxil and tenofovir disoproxil fumarate (nucleotide analogues). The advantages of relatively infrequent side effects and easy administration per oral make NAs popular treatment options. The major drawback of earlier generation NAs is the risk of emergence of drug resistance. Current international guidelines recommend the use of more potent agents with high genetic barriers to resistance including entecavir and tenofovir as first line chronic hepatitis B treatment. However, there is no consensus regarding the subsequent treatment regimens in patients with suboptimal responses to NAs. De novo combination therapy of two NAs, response-guided therapy and roadmap concept in NAs with subsequent switch or add-on therapy can also potentially improve treatment efficacy and avoid resistance.

Abstract
BACKGROUND AND AIMS Previous studies examining the relationship between hepatitis B virus (HBV) genotype B and C and response to interferon therapy in Hepatitis B e antigen (HBeAg)-positive chronic hepatitis B patients have yielded conflicting results. We aim to summarize data to reach firm conclusions on the role of HBV genotype B and C in response to interferon therapy. METHODS PubMed, Embase, and Cochrane Central Register of Controlled Trials were searched for relevant articles published up to March 2013. Odds ratios (ORs) and 95% confidence intervals (CI) were calculated by fixed- or random-effects models. Heterogeneity, sensitivity analysis, and publication bias were also assessed. RESULTS Fifteen studies were identified. All studies except for those evaluating the rate of end-of-treatment HBeAg seroconversion exhibited significant heterogeneity. There were significant differences in rates of end-of-treatment alanine aminotransferase (ALT) normalization, HBV DNA negative, and HBeAg seroconversion between the genotype B and genotype C groups, but not in HBeAg clearance. The pooled results showed higher rates of sustained ALT normalization (OR = 2.24, 95%CI 1.53-3.27), HBV DNA negative (OR = 2.60, 95%CI 1.65-4.12), HBeAg clearance (OR = 2.13, 95%CI 1.29-3.52) and HBeAg seroconversion (OR = 1.95, 95%CI 1.27-2.98) in patients with genotype B than those with genotype C. The sensitivity analysis did not alter the effects observed in the primary analysis. There was no evidence of publication bias except for HBeAg clearance rate. CONCLUSIONS The results of the current meta-analysis indicate that HBV genotype B patients receiving interferon therapy respond better to treatment compared with genotype C patients, but this needs to be further examined.

Abstract
PURPOSE It remains unclear whether chronic hepatitis B patients who undergo interferon (IFN)-induced hepatitis B e antigen (HBeAg) seroconversion have a higher risk of hepatitis B virus (HBV) reactivation and HBeAg seroreversion than those with spontaneous HBeAg seroconversion. METHODS A total of 80 and 251 non-cirrhotic patients with interferon-induced and spontaneous HBeAg seroconversion, respectively, were analyzed. RESULTS Compared to spontaneous HBeAg seroconverters, more IFN-induced HBeAg seroconverters were males (p = 0.004). For all patients, the IFN-induced HBeAg seroconverters faced a higher risk of HBV reactivation and HBeAg seroreversion than spontaneous HBeAg seroconverters (p < 0.001). For spontaneous HBeAg seroconverters, age at HBeAg seroconversion, male sex, HBV genotype C, and pre-S deletions were independent predictors of HBV reactivation. For IFN-induced HBeAg seroconverters, older age at baseline and HBV genotype C were independent predictors of HBV reactivation. To determine whether the difference in the rates of HBV reactivation or HBeAg seroreversion between two groups was age-dependent, patients were grouped and analyzed according to their age at HBeAg seroconversion (20-30, 31-39, ≥40 years). IFNs treatment was an independent factor in HBV reactivation and HBeAg seroreversion only in the groups of patients 31-39 and ≥40 years of age, but not in the group of patients 20-30 years of age. CONCLUSIONS IFN-induced rather than spontaneous HBeAg seroconversion was associated with higher risk of HBV reactivation and HBeAg seroreversion, especially in patients who were older than 30 years at HBeAg seroconversion.

Abstract
Although chronic hepatitis B (CHB) is a global health threat, it is now a preventable and treatable disease. Seven agents have been approved for the treatment of CHB. Although many patients prefer potent long-term nucleos(t)ide analogues (NAs) as the first-line therapy because they are convenient to use and well-tolerated, a finite duration of pegylated interferon (PEG-IFN) is still an attractive strategy because it provides higher rates of off-therapy host immune control over hepatitis B virus (HBV) compared with NAs. In addition, the rates of HBeAg/HBsAg loss or seroconversion increase over time in patients who respond to PEG-IFN therapy. Nevertheless, these benefits are limited to 30% of all patients, and significant adverse effects are still a concern. Therefore, patients who can benefit most from PEG-IFN therapy should be more carefully selected according to baseline host and viral predictors, such as age, ALT level, viral load, HBV genotype and HBV mutants. In addition, on-treatment predictors including HBV DNA, HBeAg and HBsAg kinetics, can help decide who should continue or discontinue PEG-IFN and shift to NA. Understanding these factors can help determine personalized PEG-IFN therapy for CHB patients. In the near future, the treatment paradigm of CHB should be tailored on the basis of viral (HBV DNA level, HBV genotype and HBV mutants) and host (age, gender, ALT level and host genetic polymorphisms) factors, disease status (stage of fibrosis and comorbidities) and the selection of antiviral agents (immunomodulatory effect, antiviral potency, adverse effects and rate of drug resistance).

Abstract
Hepatic flares occurred in two patients with HBV/HIV coinfection following the commencement of antiretroviral therapy (ART). At that time, the HIV RNA and HBV DNA levels had decreased. The results of liver biopsies showed lymphocytic infiltration that was diffusely positive for CD8(+) T cells in the portal areas and lobules. These findings suggested HBV-related immune reconstitution inflammatory syndrome (IRIS). The alanine aminotransferase levels of both patients gradually decreased with the continuation of ART. Because there are few reports of the liver histology of HBV-related IRIS, these cases provide a better understanding of the pathogenesis of HBV-related IRIS.

Abstract
A number of nucleoside analogues such as lamivudine (LAM), actually used for the treatment of chronic hepatitis B, can suppress HBV DNA replication, improve transaminase level and liver histology, and enhance the rate of hepatitis B e antigen (HBeAg) clearance. The responses to LAM therapy involve HBeAg clearance and HBV DNA conversion of negative. However, the associations between HBV genotype B/C and response to LAM therapy remain ambiguous. The aim of this meta-analysis is to determine more precise estimations of the relationship. All the publications on the associations between HBV genotype B/C and response to LAM (HBeAg clearance and HBV DNA conversion of negative) through June 2013 were collected. Relative risk (RR) with 95% confidence intervals (95% CI) was calculated in fixed or random model, I2 was calculated to examine heterogeneity, and funnel plots were plotted to examine small study effects with Stata 11 software. Overall, for HBeAg clearance and genotype B/C, the RR (95% CI) was 1.27 (0.94–1.71), while for HBV DNA conversion of negative and genotype B/C, the RR (95% CI) was 1.07 (0.98–1.17). HBV genotype B/C shows no significance associations with response to lamivudine therapy (HBeAg clearance and HBV DNA conversion of negative).

Abstract
Persistent viral eradication or suppression through a defined course of Pegylated-interferon (PegIFN) or the administration of a long-term potent nucleot(s)ide analogues (NUCs) can impact positively the natural course of HBV infection by preventing disease progression. Despite the higher rates of off-therapy response achieved with PegIFN compared with NUC, its benefits are restricted to a subgroup of patients only. To increase the rates of patients who may benefit from PegIFN treatment, minimizing the adverse events, careful patient selections based on baseline features and on treatment HBsAg kinetics for individual treatment optimization are required.

Abstract
BACKGROUND/AIMS Chronic hepatitis B (CHB) infection is a serious public health problem due to its potential liver disease sequelae and highly expensive medical costs such as the need for liver transplantation. The aim of this study was to quantify the burden of active CHB in terms of mortality and morbidity, the eligibility of antiviral treatment and to assess various treatment scenarios and possible salvage combinations for cost-effectiveness. METHODS A population cohort from a large data base of chronic hepatitis B patients was constructed and stratified according to 10-year age groups, the prevalence of HBsAg, HBV DNA level, ALT level, HBeAg status and the presence of cirrhosis. An age-specific Markov model for disease progression and cost-effectiveness analysis was constructed and calibrated for the specific population setting. RESULTS Of about 3.2 million estimated HBsAg carriers, 25% are eligible for treatment. If the active cohort remains untreated, 31% will die due to liver related complications. Within a 20-year period, 11% will have developed decompensated cirrhosis, 12% liver cancer and 6% will need liver transplantation. Quality adjusted life years (QALYs) for the no treatment scenario ranged from 9.3 to 14.0. For scenarios with antiviral treatment, QALYs ranged from 9.9 to 14.5 for lamivudine, 13.0-17.5 for salvage therapy, and 16.6-19.0 for the third generation drugs entecavir and tenofovir. CONCLUSION In a country with considerable amount of active CHB patients, monotherapy with a highly potent third generation drug has the most health-gain, and is cost-effective in both HBeAg-positive and negative in all stages of liver disease.

Abstract
In the past decade, broadened therapeutic options of oral direct antiviral agents for the treatment of chronic hepatitis B infection include: Lamivudine, Adefovir Dipivoxil, Telbivudine, Entecavir and Tenofovir Disoproxil Fumarate. These direct oral antiviral agents effectively suppress the replication of the virus and reduce the risk of potential liver-related complications. However, prolonged use of these nucleos(t)ide analogues has been associated with drug resistance that compromises the initial clinical benefits. Moreover, the oncogenic risk of mutations due to prolonged nucleos(t)ide analogue therapy needs to be further investigated by in vitro and in vivo studies. In the current era of potent nucleotide analogues, new data are emerging, we are still facing the pool of patients who have developed resistance to the prior generation of nucleos(t)ide analogues. This paper aims to focus on incidence of antiviral drug resistance and virological breakthrough, prudent selection of initial therapy, on-treatment monitoring for drug resistance and revise treatment strategies for patients with resistant virus.

Abstract
Large volume of new data on the natural history and treatment of chronic hepatitis B virus (HBV) infection have become available since 2008. These include further studies in asymptomatic subjects with chronic HBV infection and community-based cohorts, the role of HBV genotype/naturally occurring HBV mutations, the application of non-invasive assessment of hepatic fibrosis and quantitation of HBV surface antigen and new drug or new strategies towards more effective therapy. To update HBV management guidelines, relevant new data were reviewed and assessed by experts from the region, and the significance of the reported findings was discussed and debated. The earlier "Asian-Pacific consensus statement on the management of chronic hepatitis B" was revised accordingly. The key terms used in the statement were also defined. The new guidelines include general management, indications for fibrosis assessment, time to start or stop drug therapy, choice of drug to initiate therapy, when and how to monitor the patients during and after stopping drug therapy. Recommendations on the therapy of patients in special circumstances, including women in childbearing age, patients with antiviral drug resistance, concurrent viral infection, hepatic decompensation, patients receiving immune suppression or chemotherapy and patients in the setting of liver transplantation and hepatocellular carcinoma, are also included.
