Abstract
Serum hepatitis B surface antigen (HBsAg) level < 100 IU/ml and undetectable hepatitis B virus (HBV) DNA have been recently proposed as an alternate endpoint of "partial cure" in chronic hepatitis B (CHB). We investigated clinical outcomes of hepatitis B e antigen (HBeAg)-negative CHB patients with HBsAg <100 IU/ml and undetectable HBV DNA. Treatment-naïve HBeAg-negative CHB patients with undetectable HBV DNA and normal alanine aminotransferase were retrospectively included from three institutions. Patients were classified into the low HBsAg group (<100 IU/ml) and the high HBsAg group (≥100 IU/ml). Liver fibrosis was evaluated by noninvasive tests (NITs). A total of 1218 patients were included and the median age was 41.5 years. Patients with low HBsAg were older (45.0 vs. 40.0 years, P < 0.001) than those in the high HBsAg group, while the NIT parameters were comparable between groups. During a median follow-up of 25.7 months, patients with low HBsAg achieved a higher HBsAg clearance rate (13.0% vs. 0%, P < 0.001) and a lower rate of significant fibrosis development (2.2% vs. 7.0%, P = 0.049) compared to patients with high HBsAg. No patient developed HCC in either group. HBsAg level was negatively associated with HBsAg clearance (HR 0.213, P < 0.001) and patients with HBsAg < 100 IU/ml had a low risk of significant fibrosis development (HR 0.010, P = 0.002). The optimal cutoff value of HBsAg for predicting HBsAg clearance was 1.1 Log10 IU/ml. Treatment-naïve HBeAg-negative CHB patients with HBsAg <100 IU/ml and undetectable HBV DNA had favourable outcomes with a high rate of HBsAg clearance and a low risk of fibrosis progression.

Abstract
Background Among the advantaged population with clinical cure of chronic hepatitis B, chronic inactive hepatitis B virus carriers (IHCs) and nucleoside analog-experienced patients have similar serological manifestations. This study established non-interferon-treated groups as controls to compare the efficacy of pegylated interferon α-2b (Peg-IFNα-2b) in achieving clinical cure between IHCs and nucleoside analog (NA)-experienced patients. Method A total of 270 patients were enrolled in this observational study. The IHC cohort comprised 55 patients who received Peg-IFNα-2b (Peg-IFN group), and the other 70 patients did not receive any antiviral treatment (untreated group). Patients treated with NAs were divided into two groups: one group (70 patients) receiving NA add-on Peg-IFNα-2b therapy regimen (NA add-on Peg-IFN group) and another group (75 patients) receiving continuous NA monotherapy (NA group). The primary endpoints were hepatitis B surface antigen (HBsAg) clearance and HBsAg seroconversion at 48 weeks and 72 weeks. Results At 48 weeks, 65.5% (36/55) and 52.9% (37/70) patients achieved HBsAg clearance in the Peg-IFN group and NA add-on Peg-IFN group, respectively (p = 0.156). HBsAg seroconversion was achieved in 47.3% (26/55) of the Peg-IFN group and 34.3% (24/70) of the NA add-on Peg-IFN group (p = 0.141). At the follow-up of 72 weeks, 36 patients in the Peg-IFN group achieved HBsAg loss (65.5%, 36/55), and 33 patients in the NA add-on Peg-IFN group achieved HBsAg clearance (47.1%, 33/70), which were significantly higher than in the Peg-IFN group (p = 0.041). The HBsAg seroconversion rates in the Peg-IFN group and NA add-on Peg-IFN group at 72 weeks were 45.5% (25/55) and 32.9% (23/70), respectively (p = 0.151). No patient achieved HBsAg clearance or seroconversion in the NA group and untreated group. Furthermore, the receiver operating characteristic curve showed baseline HBsAg< 72 IU/mL, and the decline of HBsAg of more than 80% and 98% from baseline to 12 and 24 weeks provided good predictions for HBsAg clearance. Meanwhile, 77% of patients with baseline HBsAg< 100 IU/mL achieved a clinical cure at 48 weeks. Conclusion Peg-IFNα-2b results in a high rate of HBsAg clearance and seroconversion in both IHCs and NA-experienced patients, especially for those patients who have HBsAg below 100 IU/mL.

Abstract
Off-treatment HBsAg reversion occurs in a considerable number of chronic hepatitis B(CHB) patients after IFN(interferon)-induced HBsAg clearance. HBV vaccination protects the general population against HBV infection. However, it remains unclear whether HBV vaccination could prevent off-treatment HBsAg reversion in CHB patients with HBsAg clearance. CHB patients (n = 199) with HBsAg clearance were included in the current study, comprising spontaneous HBsAg clearance group (n = 51), NA (nucleoside/nucleotide analogues)-induced group (n = 36) and IFN-induced group (n = 112). Log-rank test was performed to compare the cumulative incidences of HBsAg reversion between groups. Cox regression model was used to identify the factors associated with off-treatment HBsAg reversion. The 5-year cumulative incidence of HBsAg reversion in IFN-induced group was significantly higher than that in NA-induced group or spontaneous group (27.6% vs. 3.3% vs. 8.1%, both p < .05). In IFN-induced group, 66.7% of CHB patients received HBV vaccination. The cumulative incidence of HBsAg reversion in individuals with strong responses to HBV vaccination (HBsAb level >100mIU/ml) was significantly lower than that in those with weak responses to HBV vaccination (HBsAb level ≤100mIU/ml) or without HBV vaccination in IFN-induced group (7.7% vs. 58.5% vs. 31.9%, both p < .05). Multivariate Cox regression analysis confirmed strong responses to HBV vaccination were independently associated with a lower cumulative incidence of HBsAg reversion after IFN-induced HBsAg clearance (HR = 0.246, 95%CI: 0.066-0.907, p = .035). HBV vaccination has potential to prevent off-treatment HBsAg reversion in CHB patients after IFN-induced HBsAg clearance via a sufficiently high level of HBsAb, helping clinicians optimize the clinical management of such patients.

Abstract
The population of inactive HBsAg carriers (IHCs) is enormous, and it is often overlooked because of the insidious progression and mild severity of the disease. With the continuous enrichment and consolidation of research evidence, the population of IHC has obtained a high clinical cure rate through a treatment strategy based on pegylated interferon α and a stronger treatment intention. This article reviews the definition and treatment recommendations of IHCs in current domestic and international guidelines, as well as the disease progression and clinical cure research progress, so as to provide a reference and basis for scientific management and rational therapeutics.

Abstract
BACKGROUND HBsAg Next assay (HBsAgNx) claims improved detection of HBsAg. The aim was to investigate its performance in ascertaining HBsAg loss, ability to detect HBsAg in various phases of HBV infection, specificity and its amenability to in-house neutralization. METHODS Analytical sensitivity was investigated using NIBSC standard (3rd WHO-IS). For clinical performance, out of 91,962 samples tested for HBsAg (Qual-II), 512 samples consisting of 170 cases with evidence of HBsAg loss during treatment (n = 116) and without treatment (n = 54), acute-hepatitis B (n = 90) and acute exacerbation of chronic-hepatitis B (n = 41), acute-hepatitis A (n = 24) and acute-hepatitis E (n = 9) positive, HIV-1 positive (n = 20), non-HBV, HAV and HEV related acute-hepatitis (n = 81) and HBsAg prozone (n = 14) as well as in-house neutralization (n = 63) were included. RESULTS The calculated limit of detection (LOD) was 0.004 IU/mL. Of the 170 patients with apparent HBsAg loss, 18/116 (15.5%) among treated and 15/54 (27.7%) with spontaneous clearance were positive in HBsAgNx (p < 0.0001). Additionally, it detected HBsAg in 12/95 (12.6%) and 6/34 (17.6%) patients who were HBV DNA negative in treatment experienced and spontaneous clearance groups respectively (p < 0.001). The specificity of HBsAgNx was comparable to HBsAg Qual-II. The signal-intensity of HBsAgNx was significantly higher than HBsAg Qual-II across various phases of HBV infection and prozone samples. CONCLUSION HBsAgNx significantly enhanced the accuracy of HBsAg detection without compromising the specificity in ascertaining HBsAg loss. The performance was superior in various phases of HBV infection including samples that exhibited prozone effect. Furthermore, it is amenable to cost-effective in-house neutralization to confirm low HBsAg levels.

Abstract
Little is known about the treatment of patients with hepatitis B surface antigen (HBsAg) recurrence after being clinically cured by peginterferon alpha(peg-IFN-α)-based regimens. This study aimed to investigate the efficacy and safety of peg-IFNα-2b in re-treating patients with HBsAg recurrence after stopping peg-IFN α-based regimens. In this two-center, prospective observational study, 33 patients with HBsAg recurrence after stopping peg-IFN α-based regimens were enrolled and re-treated with an individualized course of peg-IFN α-2b. The hepatitis B virus (HBV) vaccine could be injected immediately after HBsAg clearance, according to patients’ willingness. All patients were monitored and followed-up for 48 weeks after peg-IFN α-2b re-treatment stop. The primary endpoint was HBsAg clearance at the end of follow-up. At baseline, all patients had HBsAg levels of <10 IU/mL and undetectable HBV DNA, with the median HBsAg level of 1.66 (0.56−2.87) IU/mL. After a median of 24 (24−30) weeks of peg-IFN α-2b re-treatment, 87.9% (29/33) of the patients achieved HBsAg clearance again and 66.7% (22/33) of the patients achieved HBsAg seroconversion. At the end of follow-up, the HBsAg clearance and HBsAg seroconversion rates decreased to 78.8% (26/33) and 51.5% (17/33), respectively. Furthermore, 88.9% (16/18) of the patients with HBsAg clearance benefited from receiving the HBV vaccine therapy. Generally, both peg-IFN α-2b and HBV vaccine therapy were well tolerated. A high functional cure rate can be achieved by a short-course of peg-IFN α-2b re-treatment in patients with HBsAg recurrence after stopping peg-IFN α-based regimens. Furthermore, injecting HBV vaccine is beneficial after HBsAg clearance.

Abstract
Purpose HBsAg clearance represents clinical cure for patients with hepatitis B, but remains difficult to obtain for most HBV-infected patients. Recent studies have shown that inactive HBsAg carriers treated with pegylated interferon can achieve higher clinical cure rates, which may imply that the lower the baseline HBsAg quantification, the higher HBsAg clearance rate. Therefore, this study further investigated the HBsAg clearance rate in inactive HBsAg carriers with low level of HBsAg (<200 IU/ml) treated with pegylated interferon. Methods This is a prospective cohort study. Inactive HBsAg carriers with HBsAg<200 IU/ml were divided into treatment and control groups. Pegylated interferon was administered to the patients in therapeutic group for 96 weeks. The patients in control group underwent 96 weeks of observation without any anti-viral treatment. All patients were tested for HBsAg, anti-HBs, HBV DNA, liver function, blood count, thyroid function, thyroid antibodies and autoantibodies at baseline, week 12, 24, 36, 48, 60, 72, 84 and 96. Controlled attenuation parameter (CAP) and liver stiffness measure (LSM) were evaluated at baseline and week 96. Patients were classified into no steatosis, mild steatosis, moderate steatosis and severe steatosis according to the value of CAP. Results A total of 174 inactive HBsAg carriers with HBsAg<200IU/ml were enrolled, including 84 in the treatment group and 90 in the control group. In the treatment group, HBsAg clearance rate was 30.77% (24/78) at week 48, and increased to 57.69% (45/78) at week 96. HBsAg clearance occurred in 2 patients with a clearance rate of 2.27% (2/88) in control group, The HBsAg clearance rate of the treatment group was significantly higher than that of the control group (P<0.001). HBsAg clearance was significantly higher in patients with moderate steatosis than in those without steatosis (74.07% vs. 48.15%, p=0.008) at week 96. Conclusion High HBsAg clearance rate could be obtained for inactive HBsAg carriers with HBsAg< 200 IU/ml treated with peginterferons. Inactive HBsAg carriers with moderate hepatic steatosis are more sensitive for the treatment.

Abstract
Purpose Our recent study showed a high rate of HBsAg clearance in inactive HBsAg carriers (IHCs) treated with pegylated IFN (PEG-IFN). To better understand the immune-mediated component of HBsAg clearance, this study investigated the role of serum immunoglobulin G (IgG) and its subclasses in predicting HBsAg clearance in IHCs with PEG-IFN therapy. Methods In this study, IHCs received PEG-IFN for 96 weeks. Subjects who achieved clearance of HBsAg were considered responders (R group), and those in whom HBsAg was not cleared were considered non-responders (NR group). The HBsAg, ALT, and serum lgG subtypes (lgG1, IgG2, IgG3, lgG4) were tested at baseline, and at 12 and 24 weeks of treatment. To evaluate the factors in predicting HBsAg clearance, univariate and multivariate logistic regression analyses were performed. The receiver operator characteristic curves and the area under the receiver operator characteristic curve (AUROC) were used to evaluate prognostic values. Results Our results showed that 39 cases obtained HBsAg clearance (group R), while 21 cases did not (group NR). There was no significant difference in age, ALT, and AST levels between the two groups. The serum levels of IgG1, lgG2, lgG3 and lgG4 at baseline, and at 12 and 24 weeks were significantly lower in IHC with HBsAg clearance than in the NR group. Univariate logistic regression analysis showed that serum IgG1, IgG2, IgG3, and IgG4 levels at baseline, and at 12, and 24 weeks were all strong predictors of HBsAg clearance. In all indicators, lgG2 had the highest AUROC at baseline and lgG3 the highest AUROC at week 12. A multifactor logistic analysis was performed with y=33.933-0.001*BaselinelgG1-0.002*BaselinelgG2. The area under the curve was 0.941 with 100% sensitivity and 76.19% specificity. Conclusion Together, our findings suggest that serum IgG has a higher predictive value compared to the convention predictors of HBsAg and ALT for HBsAg clearance and thus may be a better clinical predictor of HBsAg clearance in IHCs.

Abstract
The integration of HBV DNA is one of the carcinogenic mechanisms of HBV. The clearance of HBV integration in hepatocyte is of great significance to cure chronic HBV infection and thereby prevent the occurrence of HBV-related hepatocellular carcinoma (HCC). However, the low throughput of traditional methods, such as Alu-PCR, results in low detecting sensitivity of HBV integration. Although the second-generation sequencing can obtain a large amount of sequencing data, but the sequencing fragments are extremely short, so it cannot fully explore the characteristics of HBV integration. In this study, we used the third-generation sequencing technology owning advantages both in sequencing length and in sequencing depth to analyze the HBV integration characteristics in PLC/PRF/5 cells comprehensively. A total of 4,142,311 cleaning reads was obtained, with an average length of 18,775.6 bp, of which 84 reads were fusion fragments of the HBV DNA and human genome. These 84 fragments located in seven chromosomes, including chr3, chr4, chr8, chr12, chr13, chr16, and chr17. We observed lots of DNA rearrangement both in the human genome and in HBV DNA fragments surrounding the HBV integration site, indicating the genome instability causing by HBV integration. By analyzing HBV integrated fragments of PLC/PRF/5 cells that can potentially express HBsAg, we selected three combinations of sgRNAs targeting the integrated fragments to knock them out with CRISPR/Cas9 system. We found that the sgRNA combinations could significantly decrease the level of HBsAg in the supernatant of PLC/PRF/5 cells, while accelerated cell proliferation. This study proved the effectiveness of third-generation sequencing to detect HBV integration, and provide a potential strategy to reach HBsAg clearance for chronic HBV infection patients, but the knock-out of HBV integration from human genome by CRISPR/Cas9 system may have a potential of carcinogenic risk.

Abstract
BACKGROUND & AIMS The effectiveness and safety of peginterferon alpha (peg-IFN-α) monotherapy in inactive hepatitis B virus (HBV) carriers (IHCs) have not been fully evaluated. METHODS This observational study prospectively enrolled 298 IHCs in China from 2015 to 2019. Participants were given the right to choose to either receive peg-IFN-α monotherapy (treatment group, n = 142) or be monitored without treatment (control group, n = 156) according to their wishes. The scheduled treatment duration was 48 weeks. All participants were followed up to 72 weeks. The main efficacy endpoint was hepatitis B surface antigen (HBsAg) clearance at 72 weeks. RESULTS Baseline characteristics were similar between both groups. At 72 weeks, intention-to-treat analysis showed that the rates of HBsAg clearance and seroconversion of the treatment group were 47.9% (68/142) and 36.6% (52/142), respectively, which were significantly higher than the HBsAg clearance rate of 1.9% (3/156) and the seroconversion rate of 0.6% (1/156) in the control group (both P < .001). Baseline HBV DNA < 20 IU/mL, lower HBsAg levels at baseline, 12 and 24 weeks, alanine aminotransferase elevation at 12 weeks, and greater HBsAg reduction from baseline to 12 and 24 weeks were independent predictors of HBsAg clearance. Generally, the therapy was well tolerated. Only five participants discontinued therapy as a result of peg-IFNα-related adverse events. CONCLUSIONS Peg-IFN-α monotherapy results in high rates of HBsAg clearance and seroconversion and the treatment is safe for IHCs.

Abstract
Objective: To explore the possibility of hepatitis B core antibody (anti-HBc) in predicting hepatitis B virus surface antigen (HBsAg) clearance. Methods: Sixty cases with chronic hepatitis B who were previously treated with peginterferon α-2a combined with nucleos(t)ide analogues (NAs) antiviral therapy were divided according to the HBsAg clearance or non-clearance; 41 cases in the clearance group and 19 cases in the non-clearance group. Double antigen sandwich method was used to detect patients anti-HBc quantitative levels during the course of treatment and at baseline, 24, 48, 72 and 96 weeks. Logistic regression analysis and receiver operating characteristic curve (ROC) were used to evaluate the predictive ability of related influencing factors for HBsAg clearance. Results: With antiviral treatment prolongation, anti-HBC quantitative levels in the overall population showed a progressive downward trend in the clearance group and the non-clearance group, but the anti-HBC level in the clearance group was significantly higher than non-clearance group at the baseline and successive detection time points during the antiviral treatment (P < 0.05). Multivariate logistic regression showed that baseline quantitative anti-HBC level, HBsAg decline at week 24 (log10 IU / ml), and alanine aminotransferase (ALT) > 1.5 times the upper limit of normal value (ULN) were all influencing factors for HBsAg clearance during the treatment (OR = 0.156, P = 0.026; OR = 0.134, P = 0.023; OR = 0.239, P = 0.028). Among them, the baseline quantitative anti-HBc level was the best independent predictor for HBsAg clearance (OR = 0.235; P = 0.004), and the sensitivity and specificity for predicting HBsAg clearance at > 3.40 log10 IU/ mL were 56.1% and 89.5%, respectively. Logistic regression model was used as a reference to construct combined predictors in order to improve the prediction accuracy. Among them, the combined factor 3 had the highest predictive value (the area under the ROC curve had reached up to 0.870; 95%CI was 0.781 ~ 0.960; P < 0.001). The cut-off value of combined factor 3 was > 0.386, and the sensitivity and specificity were 80.5% and 78.9%, respectively. In addition, the combined index had further improved the predictive value, which is the combination of any two or more indexes based on the baseline quantitative anti-HBC level, and HBsAg clearance predictive rate had reached 94.12% ~ 100%. Conclusion: The baseline quantitative anti-HBC level has the highest predictive value for HBsAg clearance. The combination of ALT > 1.5×ULN and HBsAg decline at 24 weeks during the treatment can more precisely predict HBsAg clearance. Therefore, it is a reliable non-invasive biomarker.

Abstract
BACKGROUND The outcome of hepatitis B virus (HBV) infection is significantly affected by host immune response; herein, we aim to dissect the effect of L-carnitine (L-Cn) on germinal center (GC)-related immune cells and the influence on the prognosis of HBV infection. METHODS In vitro and in vivo experiments were performed in patients with chronic HBV infection and a hydrodynamic injection mouse model. RESULTS In vitro assays revealed that L-Cn significantly reduced GC-related immune responses and enhanced immunosuppressive profiles. Intriguingly, L-Cn released from lysed hepatocytes was associated with the degree of liver damage. Besides, the administration of L-Cn in an HBV mouse model resulted in delayed clearance of HBsAg in serum and decreased GC formation in the spleen. Notably, patients with HBsAg loss showed decreased plasma L-Cn levels, and longitudinal observations found that low baseline levels of L-Cn were associated with a favorable treatment response in chronic hepatitis B patients. CONCLUSIONS The suppressive effect of hepatocyte-derived L-Cn on GC-related immune cells may contribute to the inability of HBsAg clearance in chronic HBV infection, indicating that L-Cn might serve as a potential therapeutic target for the treatment of HBV infection.

Abstract
Hepatitis B surface antigen (HBsAg) clearance is regarded as the ideal endpoint for antiviral treatment in terms of drug withdrawal safety and improvements in prognosis. However, the overall rate of HBsAg clearance is low and differs based on treatment method and course. The recent application of combined and extended treatment strategies have improved the HBsAg clearance rate, and several patients achieved HBsAg clearance in clinical treatment. In addition, the durability of and clinical outcomes after HBsAg clearance have become the focus of both researchers and clinicians. This article reviews HBsAg clearance in terms of accessibility, durability, improvements in prognosis and relevant advances.

Abstract
BACKGROUND & AIMS Discontinuation of nucleos(t)ide analogues (NA) remains a debatable issue in HBeAg-negative chronic hepatitis B (CHB). This study aimed to address the outcome of HBeAg-negative CHB patients who discontinued NA therapy. METHODS This prospective study included 57 non-cirrhotic HBeAg-negative Caucasian CHB patients who discontinued NA therapy after median virological remission of 6 years. All patients had regular blood tests. Virological relapse was defined as HBV DNA > 2000 IU/mL or >20 000 IU/mL and biochemical relapse as ALT > ULN (40 IU/mL) or >2xULN. All patients with retreatment predefined criteria restarted entecavir or tenofovir. RESULTS Of the 57 patients, 29 remained without retreatment after median follow-up of 65 months (range: 36-87) following treatment discontinuation. At 3, 6, 12, 24, 36 and 48 months, cumulative rates of retreatment were 16%, 20%, 32%, 35%, 46% and 50%, while the proportion of patients with HBV DNA < 2000 IU/mL and ALT < ULN were 73%, 60%, 52%, 52%, 47% and 37% respectively. All patients had virological and biochemical response after retreatment. No patient developed liver failure, hepatocellular carcinoma or death. Cumulative rates of HBsAg loss were 2%, 4%, 7%, 10% and 20% at 3, 6, 12, 24 and 36 months. HBsAg levels < 100 IU/mL at the end of NA treatment could predict HBsAg loss (P = .001). CONCLUSIONS Our study supports that NA therapy can be safely stopped in non-cirrhotic patients with HBeAg-negative CHB. Over a median follow-up of more than 5 years, half of the patients remained without retreatment with a substantial proportion of them achieving functional cure.

Abstract
Hepatitis B virus (HBV) infection and its related liver diseases are important health problems worldwide, particularly in the Asia-Pacific region. For the past 4-5 decades, Taiwan's government and scientists have cooperated together to control this virus infection and its related liver diseases. These efforts and achievements have made progress toward the elimination of HBV. Taiwan's government initiated the Viral Hepatitis Control Program (VHCP) in the1970s, and then launched the national vaccination program in 1984. This universal vaccination program effectively decreased the rate of hepatitis B carriage and the development of hepatocellular carcinoma (HCC) in the younger generation. Since 2003, approved anti-HBV treatments were reimbursed nationwide. This reimbursement program resulted in a higher uptake of anti-HBV treatments, which contributed to a decrease in liver-related disease progression and subsequently reduced attributable mortality in Taiwan. This experience can be shared by countries in other parts of the world regarding the control of chronic viral hepatitis B.

Abstract
BACKGROUND Hepatitis B virus (HBV) is a hepatotropic virus that can cause acute and chronic liver damage. According to the world health organization 257 million people are infected with chronic HBV infection worldwide. Super-infection with other hepadnaviruses, including hepatitis A virus (HAV), hepatitis C virus, hepatitis D virus, and hepatitis E virus is associated with increased risk of acute liver failure in patients with chronic HBV.
CASE SUMMARY Here, we report a case of a 47-year old male patient with HBV-related compensated Child A cirrhosis, who presented with general fatigue, malaise and laboratory signs of acute hepatitis. Although the patient was regularly seen at a specialized university liver unit, the HAV vaccination status was unclear. Acute HAV super-infection was diagnosed by positive serological and polymerase chain reaction analysis. Following acute HAV super-infection, spontaneous HBsAg elimination and development of an anti-HBs titer were observed.
CONCLUSION This case illustrates the importance of carefully checking the vaccination status. In our patient, unspecific immunological responses to HAV led to functional cure of HBV.

Abstract
BACKGROUND Recurrence is common for patients with chronic hepatitis B (CHB) who achieved hepatitis B virus (HBV) surface antigen (HBsAg) clearance after antiviral treatment. The aim of the study is to explore the possibility of quantitative hepatitis B core antibody (Anti-HBc) level as a biomarker to predict recurrence. METHODS A total of 73 patients with HBsAg clearance were enrolled in this study, 16 cases with recurrence and 57 cases of non-recurrence. A newly developed double-sandwich Anti-HBc immunoassay was used to detect the quantitative Anti-HBc level before therapy (baseline) and at the end of therapy. Logistic regression analysis was used to evaluate the predictive ability of quantitative Anti-HBc levels for recurrence. RESULTS Quantitative Anti-HBc levels at the end of therapy in both recurrence and non-recurrence groups were significantly lower than those of before therapy (P < 0.001). In addition, the declining trend of the recurrence group was significantly greater than that of the non-recurrence group (0.71 log10 vs. 0.45 log10 IU/mL, P = 0.026). Quantitative Anti-HBc levels in non-recurrence group were higher than those in recurrence group at baseline and drug withdrawal (P = 0.023, P < 0.001). Multivariable analysis showed that Anti-HBc level at drug withdrawal alone was associated with recurrence (OR = 0.116, P = 0.037). At Anti-HBc level >2.3386 log10 IU/mL, the predictive sensitivity and specificity for recurrence were 80.0% and 71.9%. CONCLUSIONS Quantitative Anti-HBc level can be used as a potential predictor of recurrence after HBsAg clearance. Anti-HBc level at the drug withdrawal has better predictive value than the baseline.

Abstract
AIM To assess the efficacy and safety of long-term treatment with nucleos(t)ide analogues in patients with chronic hepatitis B. MATERIALS AND METHODS We conducted an observational study in 101 chronic hepatitis B (HBeAg-negative and HBeAg-positive) patients treated (≥3 years) with entecavir, tenofovir or telbivudine. RESULTS Treatment with entecavir and tenofovir was associated with high rate of virologic and biochemical response (>95%) and HBeAg seroconversion (93% and 67%, respectively). Cumulative rate of virologic resistance was 0; 3.1% and 43.5% for tenofovir, entecavir and telbivudine, respectively. Long-term nucleos(t)ide analogues treatment resulted in a regress of liver fibrosis (from 8.92 to 7.18 kPa, р<0.0001) and reduction in the number of patients with advanced fibrosis (from 48.1% to 13.8%, р<0.0001). Entecavir and tenofovir were safe and well tolerated, while treatment with telbivudine was associated with development of myopathy in 13% of cases. CONCLUSION Entecavir and tenofovir might be recommended for the treatment of chronic hepatitis B because of having potent antiviral effect, high genetic barriers against resistance and good safety.

Abstract
Background To investigate the predictive capability of microRNAs (miRNAs) prior treatment for HBsAg clearance in chronic hepatitis B (CHB) treated with pegylated interferon α-2a (PEG-IFNα-2a). Methods The treatment effect was determined by HBsAg clearance and subjects were classified into HBsAg clearance group and non HBsAg clearance group. Differential miRNAs expression in peripheral blood mononuclear cells (PBMC) was screened using microarrays in an identification cohort (n = 20) and validated by quantitative reverse-transcription polymerase chain reaction (qRT-PCR) in a confirmation cohort (n = 47). Receiver operating characteristic curve (ROC), logistic regression and gene ontology (GO)/Pathway analyses were used to evaluate the predictive capability of selected miRNAs for HBsAg clearance and determine their mechanistic roles. Results Twenty-seven subjects (40.3%) acquired HBsAg clearance, ten in the identification cohort and seventeen in the confirmation cohort. Four miRNAs out of twelve (miR-3960, miR-126-3p, miR-335-5p, miR-23a-3p) were verified to be differential expressed by qRT-PCR in the confirmation cohort. Their expression patterns were consistent with the microarray results. Their levels were lower in the response group compared with the nonresponse group (p < 0.05). The areas under curve (AUC) were 0.8333 (p = 0.001), 0.751 (p = 0.01), 0.7294 (p = 0.013), 0.6275 (p = 0.094) and positive predict values (PPV) were 84.62, 60.00, 70.00, 28.57% for miR-3960, miR-126-3p, miR-335-5p, and miR-23a-3p respectively. The AUC and PPV of the combination of miR-3960 and miR-126-3p were 0.8529 and 92.31%, which were better than using miR-3960 alone, but the differences were not statistically significance (p > 0.05). Conclusions We identified differential expressed miRNAs between response and nonresponse groups of PEG-IFNα-2a treatment and demonstrated that miR-3960 was the optimal predictor for HBsAg clearance compared with other miRNAs, but it requires to be further comfired in larger cohort studies. Trial registration ChiCTR ChiCTR-ROC-16008735, registered retrospectively on 28 June, 2016.

Abstract
BACKGROUND & AIMS The difference between the long-term outcome of low-viraemic (HBV-DNA≤20 000-IU/mL, LV-AC) and inactive HBsAg carriers (HBV-DNA≤2000-IU/mL, IC) remains to be defined. We studied prospectively 153 HBeAg-negative HBsAg-carriers with baseline HBV-DNA≤20 000-IU/mL and normal transaminases. METHODS IC, LV-AC or chronic hepatitis B (CHB) (HBV-DNA persistently ≤2000-IU/mL, ≤20 000-IU/mL or >20 000-IU/mL respectively) were diagnosed after 1-year, 3-monthly monitoring. Thereafter IC and LV-AC were followed-up for additional 57.2 (8.5-158.3) months. HBV-DNA, HBsAg, HBV"core-related"Antigen (HBcrAg) and total-anti-HBc were quantified at baseline. RESULTS After the 1st year diagnostic follow-up CHB [higher HBV-DNA (P=.005), total-anti-HBc (P=.012), ALT (P=.007) and liver-stiffness (P=.021)] was identified in 20 (13.1%) carriers; baseline HBsAg≤1000IU/HBV-DNA≤2000IU/mL excluded the presence of CHB (NPV-100%). Thereafter, during the long-term follow-up none of 87 IC reactivated, 19 (21.8%) cleared HBsAg [older-age (P=.004), lower HBsAg (P<.001), higher yearly HBsAg decline (P<.001)]. Twenty-five of 46 (54.3%) LV-AC remained stable, 20 (43.5%) became IC and 1 (2.2%) developed CHB. The best single-point CHB and IC diagnostic-accuracies were total-anti-HBc (84.2%, NPV-98.2%) and HBV-DNA/total-anti-HBc/HBcrAg combination (89.5%, 93%-sensitivity, 84.8%-specificity) respectively. CONCLUSIONS Viraemia persistently ≤20 000-IU/mL predicts a benign clinical outcome: it was associated with transition to IC in 43% of LV-AC and to Occult HBV Infection in 20% of IC within 5-years. Nevertheless, 13.1% of individuals with low viraemia at presentation develops CHB within 1 year: 1-year HBV-DNA monitoring resulted the most accurate diagnostic approach that can be limited to at least a half of cases by the single point HBV-DNA/HBsAg quantification. The IC-diagnostic-accuracy combining HBV-DNA/total-anti-HBc/HBcrAg needs to be confirmed in further studies.

Abstract
BACKGROUND & AIMS Esophageal varices (EV) are a marker of disease severity in compensated cirrhosis due to hepatitis B virus (HBV) which predicts also the risk of hepatocellular carcinoma (HCC), clinical decompensation and anticipated liver related death. The dynamics and prognostic significance of EV in patients under long-term HBV suppression by nucleos(t)ide analogs (NUC), are poorly known. METHODS A standardized protocol (Baveno) including 414 upper gastrointestinal (GI) endoscopies was applied to 107 HBeAg-negative compensated cirrhotic patients (93% Child-Pugh A) during a median of 12 (range 2 to 17) years of NUC therapy. Patients who initially started on lamivudine (LMV) and then developed resistance (LMV-R), were rescued by early administration of adefovir, or were switched to tenofovir. Surveillance included serum HBV DNA every three months and abdominal ultrasound every six months. RESULTS Twenty-seven patients had baseline F1 EV which regressed in 18, remained unchanged in eight and progressed in one patient; the 12-year cumulative incidence of EV regression was 83% (95% CI: 52-92%). De novo F1/F2 EV developed in 6/80 patients with a 12-year cumulative incidence of 10% (95% CI: 5-20%). Six of seven patients with de novo varices or progression of pre-existing varices had either a clinical breakthrough due to LMV-R and/or developed a HCC. No bleedings from ruptured EV occurred, 12 patients died (9 HCC) and 15 were transplanted (13 HCC): the 12-year cumulative incidence of HCC and overall survival was 33% (95% CI: 24-42%) and 76% (95% CI: 67-83%), respectively. CONCLUSIONS Long-term pharmacological suppression of HBV in HBeAg-seronegative patients with compensated cirrhosis leads to a significant regression of pre-existing EV accompanied by a negligible risk of developing de novo EV.

Abstract
The ideal endpoint of hepatitis B virus (HBV) antiviral therapy is HBsAg loss, a difficult goal to obtain, especially in HBeAg negative patients. Herein, we report the results obtained by the addition of peg-interferon α-2a to a long-lasting nucleos(t)ide analogue therapy in a HBeAg negative, genotype D patient with steadily HBV-DNA negative/HBsAg positive values. In 2002, our Caucasian 44-year-old male patient received lamivudine and, 4 years later, added adefovir because of a virological breakthrough. In 2011, considering his young age, liver stiffness (4.3 kPa) and HBsAg levels (3533 IU/mL), we added Peg-interferon α-2a for six months (3 in combination with nucleos(t)ide analogues followed by 3 mo of Peg-interferon α-2a monotherapy). A decrease of HBsAg levels was observed after 1 mo (1.21 log) of Peg-interferon and 3 mo (1.88 log) after the discontinuation of all drugs. Later, a complete clearance of HBsAg was obtained with steadily undetectable HBV-DNA serum levels (< 9 IU/mL). HBsAg clearance by the addition of a short course of Peg-interferon α-2a represents an important result with clinical and pharmaco-economic implications, considering that nucleos(t)ide analogues therapy in HBeAg negative chronic hepatitis B patients is considered a long-lasting/life-long treatment.

Abstract
Dual hepatitis C virus (HCV)/hepatitis B virus (HBV) infection is not uncommon in HCV or HBV endemic areas and among subjects at risk of parenteral transmission. In patients dually infected with hepatitis C and B, the disease manifestations are usually more severe than those with either virus infection. In the past decade, the following issues have been resolved. In dually infected patients with active hepatitis C, combined pegylated interferon alfa plus ribavirin was effective, the treatment outcomes being similar to patients with HCV monoinfection. During long-term follow-up, the HCV response was sustained in around 97% of patients; and the long-term outcomes including the development of hepatocellular carcinoma and liver-related mortality were improved. However, several clinical issues remain to be resolved. First, host and viral factors influencing the long-term outcomes and treatment options in patients with dual HCV/HBV infection await further studies. Second, about 60% of dually infected patients with baseline undetectable serum HBV DNA levels develop HBV reactivation after the start of treatment. How to prevent and treat HBV reactivation should be clarified. Third, about 30% of dually infected patients lose hepatitis B surface antigen at 5 years after the end of combination therapy; the mechanisms need further investigations. Fourth, the optimal treatment strategies for dually infected patients with active hepatitis B or established cirrhosis should be explored in future clinical trials. Finally, the role of new direct-acting antiviral-based therapy for the treatment of patients with dual HCV/HBV infection also remains to be evaluated.

Abstract
Purpose To investigate the durability of response to peginterferon alfa-2a up to 5 years post-treatment and factors associated with response in hepatitis B e-antigen (HBeAg)-negative patients. Methods HBeAg-negative patients received peginterferon alfa-2a (180 μg/week) ± lamivudine (100 mg/day) for 48 weeks as part of a multicenter, randomized study. The planned 5-year efficacy analysis included patients (n = 230) enrolled in the long-term follow-up study. On-treatment hepatitis B surface antigen (HBsAg) decline kinetics were analyzed retrospectively in a subgroup of patients with HBsAg data available at baseline, weeks 12, 24, and 48 on-treatment, and 6 months post-treatment (n = 120). Receiver operating characteristic analyses identified the on-treatment HBsAg levels associated with response at 1 and 5 years post-treatment. Results HBV DNA ≤2,000 IU/mL and HBsAg clearance at 5 years post-treatment were achieved by 23 and 12% of patients, respectively. High rates of HBsAg clearance at 5 years post-treatment were achieved by patients with HBV DNA ≤2,000 IU/mL at 1 year post-treatment (28%). Rates of HBV DNA ≤2,000 IU/mL at 1 year post-treatment were 47.2 and 43.4% in patients with ≥10% decline from baseline at weeks 12 and 24, respectively, compared with 16.4% (p = 0.0003) and 13.2% (p < 0.0004) in patients with a <10% decline. Rates of HBsAg clearance at 5 years post-treatment were 22.6 and 22.4% in patients with ≥10% decline at weeks 12 and 24, respectively, compared with 7.5% (p = 0.0161) and 3.8% (p < 0.0001) in patients with <10% decline. Conclusions Peginterferon alfa-2a results in increasing rates of HBsAg clearance during post-treatment follow-up in HBeAg-negative patients. On-treatment decline in HBsAg is significantly associated with long-term post-treatment response.
