Abstract
Background & Aim Cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) attenuates cytotoxic T lymphocyte (CTL) activation. This study was performed to examine the relationships between CTLA-4 genotypes/haplotypes, hepatitis B surface antigen (HBsAg), and hepatitis B core-related antigen (HBcrAg) levels, and their potential impact on the clinical course of chronic HBV infection. Methods We recruited 145 treatment-naïve patients with genotype B or C chronic HBV infection who were initially hepatitis B e-antigen (HBeAg)-positive and had been followed from a mean age of 7.08 years for a total of 4,787 person-years in the study cohort. We also recruited another 69 treatment-naïve adults with genotype B or C chronic HBV infection as a validation cohort. We assessed the CTLA-4 gene single nucleotide polymorphisms rs4553808 (-A1661G)/rs5742909 (-C318T) in both cohorts, and the serum HBsAg and HBcrAg levels in the study cohort. Results CTLA-4 promoter haplotypes were associated with HBsAg and HBcrAg levels at 10 and 15 years of age in the study cohort. Patients with the CTLA-4 AA/CC haplotype showed earlier spontaneous HBeAg seroconversion (hazard ratio = 1.58; p = 0.02), and a more rapid annual decline in the serum HBsAg level than other patients (0.09 vs. 0.03 log10 IU/ml/year, p = 0.02). The CTLA-4 AA/CC haplotype was also predictive of HBeAg seroconversion in the validation cohort (p = 0.01). Conclusions Chronic HBV-infected patients with a CTLA-4 AA/CC haplotype had lower serum HBsAg and HBcrAg levels in childhood and earlier spontaneous HBeAg seroconversion. Impact and implications The role of cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) in chronic HBV-infected children has not been studied previously. In a very long-term cohort followed from childhood to adulthood, we showed that CTLA-4 haplotypes are associated with HBV biomarker levels in childhood and are correlated with the clinical course of chronic HBV infection. CTLA-4 pathway may serve as a future target for the development of therapeutic agents against HBV infection.

Abstract
BACKGROUND Studies have shown acute flares of chronic hepatitis B (CHB) might be related to immunologic changes that occur during pregnancy. However, the indicators for predicting acute flares of CHB among pregnant women still need further study. We aimed to distinguish the relevance between serum levels of HBcrAg and acute flares of CHB in pregnant women in the immune-tolerant phase of chronic HBV infection after short-course antiviral therapy. METHODS A total of 172 chronic HBV-infected pregnant women who were judged to be in the immune-tolerant phase were recruited in our research. All patients received short-course antiviral therapy with TDF. The biochemical, serological, and virological parameters were measured using standard laboratory procedures. The serum levels of HBcrAg were tested by ELISA. RESULTS Fifty-two (30.2%) out of 172 patients had acute flares of CHB. At postpartum week 12 (TDF cessation), serum HBcrAg (OR, 4.52; 95% CI, 2.58-7.92) and HBsAg (OR, 2.52; 95% CI, 1.13-5.65) were associated with acute flares of CHB. The serum HBcrAg levels were beneficial for confirmation of patients with acute flares of CHB, with an area under the ROC curve of 0.84 (95% CI, 0.78-0.91). CONCLUSIONS For pregnant women with chronic HBV infection in the immune-tolerant phase, serum HBcrAg and HBsAg levels at postpartum week 12 were associated with acute flares of CHB after short-course antiviral therapy with TDF. The serum HBcrAg level can correctly identify acute flares of CHB and may be a predictor of the need for continuing antiviral therapy after 12 weeks postpartum.

Abstract
Two novel assays have been developed, iTACT-hepatitis B core-related antigen (iTACT-HBcrAg) and iTACT-hepatitis B surface antigen (iTACT-HBsAg) assays. We investigated the longitudinal profiles of iTACT-HBcrAg- and -HBsAg in patients with HBsAg seroclearance (SC) (<0.05 IU/mL). This study comprises 60 HBV-infected patients with HBsAg SC, 27 in chronic hepatitis/liver cirrhosis (CH/LC) group and 33 in inactive carrier (IC) group. Longitudinal profiles of iTACT-HBcrAg and -HBsAg were examined using stored serum samples. The median period from HBsAg SC to iTACT-HBcrAg loss or to the last observation was longer in the CH/LC group than the IC group (39 vs. -3 months, p = 0.004), but this tendency was not observed in that by iTACT-HBsAg. Comparing the times of iTACT-HBcrAg and -HBsAg loss, the rate of patients who lost HBcrAg first was significantly higher in the IC group (p = 0.008). The cumulative incidence rate of iTACT-HBcrAg loss after HBsAg SC was higher in the IC group that the CH/LC group (p = 0.002). Patients in the CH/LC group had higher rates of detectable iTACT-HBcrAg than those in the IC group after HBsAg SC, suggesting that the presence of HBcrAg possibly contribute to the progression of chronic hepatitis B.

Abstract
INTRODUCTION Chronic hepatitis B (CHB) infection is a major global health threat and accounts for significant liver-related morbidity and mortality. An improved understanding of how hepatitis B virus (HBV) interacts with the host immune system allows the discovery of novel biomarkers and new treatment options. Viral biomarkers including hepatitis B surface antigen (HBsAg) and newer ones like HBV RNA and hepatitis B core-related antigen appear to be useful to select patients who are likely to benefit from cessation of long-term antiviral therapy. These markers can also help to confirm target engagement for novel compounds, and efficacy in HBsAg reduction and seroclearance is deemed essential as this is how the current treatment endpoint of functional cure is defined. AREAS COVERED In this review, the authors discuss the current standard of care and the gaps between such standard and the ideal goals for treatment in CHB. The authors highlight novel viral and immunological biomarkers that are potentially useful to evaluate treatment response. Novel treatment approaches in relation to these novel biomarkers are also evaluated. EXPERT OPINION Novel serum viral biomarkers and immunological markers are indispensable in the HBV functional cure program. These will likely become part of standard monitoring soon.

Abstract
It is estimated that approximately 260 million people worldwide are infected with the hepatitis B virus (HBV), which is one of the leading causes of liver disease and liver cancer throughout the world. Compared with developed countries, low-income and middle-income countries have limited access to resources and advanced technologies that require highly specialized staff for HBV diagnosis. In spite of the heavy burden caused by hepatitis B virus, 90% of people are still undiagnosed. The World Health Organization (WHO) goal of eliminating hepatitis B by 2030 seems very difficult to achieve due to the existing diagnostic infrastructure in low-resource regions. The majority of diagnostic laboratories still use hepatitis B surface antigen (HBsAg)-based tests. WHO's elimination plan is at risk of derailment due to phases like the window period, immune control, and occult HBV infection (OBI) not being detected by standard tests. Here, in this article, we are focusing on various diagnostic platforms for the better diagnosis of HBV. The aim of the elimination of HBV can only be achieved by detecting all phases of HBV infection, which can be executed by a combined approach of using new marker assays along with advanced pretesting and testing methods.

Abstract
HBeAg seroconversion is an important treatment endpoint. We aimed to identify predictors of seroconversion using serum HBsAg and hepatitis B core-related antigen (HBcrAg) in HBeAg-positive patients treated with nucleos(t)ide analogs (NAs). Data and samples from 70 HBeAg-positive patients treated with entecavir or tenofovir between January 2007 and December 2017 were retrospectively analysed. The mean follow-up period was 11 years. The predictive power for HBeAg seroconversion of HBcrAg levels at baseline and 2 years after antiviral therapy was determined using receiver operating curve analysis. Twenty-one patients (30%) achieved HBeAg seroconversion at a mean of 28 (range, 12-84) months after antiviral treatment. The median baseline HBcrAg and HBsAg levels were 6.9(5.7-7.0) vs. 5.8(5.5-6.5) log10 U/mL (p = .006), 4.9(4.5-5.1) vs. 4.5(4.1-5.0) log10 IU/mL (p = .044) in the no seroconversion group and seroconversion group, respectively. In the multivariate analysis, the serum HBcrAg levels at baseline and 2 years after antiviral therapy were predictive factors for HBeAg seroconversion ([HR]; 0.326; [CI], 0.111-0.958; p = .042 and HR, 0.4555; CI, 0.211-0.984; p = .045). HBcrAg levels≤6.5log10 U/mL at baseline and ≤5.3log10 U/mL at 2 years after antiviral therapy had sensitivities of 53.1% and 69.8%, specificities of 95.2% and 70.6%, positive predictive values of 82.6% and 50.0%, and negative predictive values of 82.6% and 84.5%, respectively, with AUROCs of 0.712 (95%CI, 0.596-0.830) and 0.745 (95%CI, 0.599-0.891) for predicting HBeAg seroconversion. In chronic hepatitis B patients treated with NAs, HBcrAg levels≤6.5log10 U/mL at baseline and ≤5.3log10 U/mL at 2 years after antiviral therapy were useful predictive factors of HBeAg seroconversion.

Abstract
Hepatitis B core-related antigen (HBcrAg) is a predictor of hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB) patients. Studies on anti-viral therapy have shown that the use of NUC therapy in HBV patients could reduce the incidence of HCC. However, the incidence of HCC continues to increase after long-term anti-viral therapy. The relationship between HBcrAg and HCC development in CHB-related liver cirrhosis (LC) patients undergoing long-term anti-viral therapy is still unclear. This study enrolled 1108 treatment-naïve CHB patients diagnosed with HBV-related LC receiving NUC therapy from April 1999 to February 2015. The baseline biomarkers, disease history, and following results were collected by the hospital. Among the 1108 patients, 219 developed HCC within a median follow-up period of 6.85 years. A multivariable Cox regression model was used, with adjustment for age, gender, FIB-4, DM, and HBsAg-HQ. The adjusted hazard ratios for the HBcrAg tertile levels were 1.70 (95%CI: 1.21, 2.39) and 2.14 (95%CI: 1.50, 3.05) for levels 3.4-4.9 and >4.9 logU/mL, respectively, compared with levels ≤3.4. The effect of the HBcrAg level on HCC incidence was found to be significantly modified by HBsAg-HQ, where lower HBsAg-HQ (≤ 3) values were associated with a significantly higher risk, but HBsAg-HQ levels >3 were not. Our results highlight that, after adjustment for potential confounding factors, patients with CHB-related LC and higher HBcrAg levels are at significant risk for HCC development, even while undergoing long-term effective anti-viral therapy. The HBcrAg level is therefore an independent risk factor for HCC development, especially for patients with HBsAg-HQ levels <3.

Abstract
HBV RNA is considered as a promising predictor in patients who discontinue nucleos(t)ide analogues (NAs). We determined HBV RNA levels in non-cirrhotic HBeAg-negative patients who discontinued NAs and assessed their predictability for 12-month outcomes. Fifty-seven patients of DARING-B study were included. HBV RNA levels were determined in stored monthly serum samples drawn at 0-3 months after end of therapy (EOT). Other markers previously determined in the same cohort including hepatitis B core-related antigen (HBcrAg) were also assessed. HBV RNA at EOT was detectable in 7% of patients, who developed virological/clinical relapse and required retreatment at month 2; in patients with undetectable EOT HBV RNA, 12-month cumulative rates of virological relapse, clinical relapse and retreatment were 68%, 28% and 21%, respectively (p ≤ 0.008). HBV RNA at month-1 after EOT was detectable in 19% of patients being associated with higher probability only of virological relapse (p = 0.001). HBV RNA levels correlated significantly to HBV DNA, HBcrAg, ALT and interferon-induced protein-10, but not HBsAg levels. Combined EOT HBV RNA and HBcrAg detection and/or HBsAg >1000 IU/ml was associated only with higher probability of retreatment having higher sensitivity and lower specificity than HBV RNA alone. In conclusion, serum HBV RNA is detectable in a minority of non-cirrhotic HBeAg-negative patients under effective long-term NAs therapy offering low sensitivity but 100% specificity for early retreatment due to severe clinical relapses after NA discontinuation. The combinations of EOT HBV RNA with HBcrAg and/or high HBsAg levels increase sensitivity but decrease specificity for prediction of retreatment after NAs withdrawal.

Abstract
OBJECTIVE This study aimed to examine the correlations between serum hepatitis B core-related antigen (HBcrAg) and hepatitis B surface antigen (HBsAg) titers in patients with hepatitis B cirrhosis and a hepatitis B virus (HBV)-DNA-negative status. METHODS We retrospectively analyzed the data and blood samples of patients who were diagnosed with HBV liver cirrhosis and an HBV-DNA negative status. These patients were hospitalized between October 2018 and October 2019 at one hospital. RESULTS A total of 180 patients were included. The median (interquartile range) HBsAg and HBcrAg concentrations were 2.77 log10 IU/mL (1.60-3.15) and 3.96 log10 U/mL (2.70-4.97), respectively. A non-linear significant relationship was found between HBsAg and HBcrAg concentrations. The inflection point was 0.58. The effect size and confidence interval on the left and right sides of the inflection point were 0.10 (-0.23-0.42) and 0.62 (0.46-0.78), respectively. When HBsAg concentrations were ≥0.58 log10 IU/mL, HBsAg concentrations were positively correlated with HBcrAg concentrations. When HBsAg concentrations increased by 1 log10 IU/mL, HBcrAg concentrations increased by 0.62 log10 U/mL (95% confidence interval: 0.46, 0.78). CONCLUSIONS There might be a non-linear relationship between HBcrAg and HBsAg concentrations in patients with hepatitis B cirrhosis and an HBV-DNA-negative status.

Abstract
Hepatitis B and C (HBV/HCV) coinfected patients have a potential risk of hepatitis B reactivation (HBVr) after direct-acting antivirals (DAAs) treatment. The study intends to investigate the predictive role of HBV biomarkers in HBVr. Forty-six HBV/HCV coinfected patients receiving DAAs were enrolled. All patients completed treatment and follow-up to the 12th-week post-DAA treatment (P12). Blood samples were measured for HBV biomarkers, including hepatitis B surface antigen (HBsAg), hepatitis B core-related antigen (HBcrAg), and HBV pregenomic RNA (HBV pgRNA). The predictive factors for HBVr after DAA treatment were analyzed. Among 31 patients without nucleot(s)ide analogue (NA) treatment, seven (22.5%, 7/31) developed HBVr without hepatitis flare-up. Patients with HBVr had higher HBsAg titers than those without HBVr from baseline to P12 (p = 0.008, 0.009, 0.004, and 0.006 at baseline, week 4, end of treatment, and P12, respectively). The baseline HBsAg level was the only predictive factor associated with HBVr (HR, 2.303; 95% CI, 1.086−4.882; p = 0.030). In predicting HBVr, a baseline HBsAg titer > 20 IU/mL had a sensitivity, specificity, positive predictive value, and negative predictive value of 85.7%, 75.0%, 50%, and 94.7%, respectively. No patient had HBVr if the baseline HBsAg titer was <8 IU/mL. Serum HBcrAg and HBV pgRNA levels had no role in predicting HBVr. In conclusion, HBV/HCV coinfected patients are at risk of HBVr after DAA treatment. The baseline HBsAg level was the predictive factor associated with HBVr. Patients with a baseline HBsAg titer < 8 IU/mL can be considered as not having HBVr.

Abstract
Several hepatitis B virus (HBV) serum markers have been identified as risk factors for liver fibrosis in patients with chronic HBV infection, and several noninvasive fibrosis tests based on serum indexes are now used to identify the severity of liver fibrosis. We aimed to identify the relationship between hepatitis B core-related antigen (HBcrAg) serum levels and liver fibrosis in treatment-naive chronic HBV infection patients. A total of 246 treatment-naive chronic HBV infection patients were enrolled in this study. All of the patients underwent liver biopsies at baseline. Using the METAVIR fibrosis stages, there were 15, 140, 50, 26 and 15 patients in the F0, F1, F2, F3 and F4 stages (METAVIR scoring system), respectively. The biochemical, serological and virological parameters were measured using standard laboratory procedures. The HBcrAg serum levels of the patients were examined via ELISA. HBcrAg serum levels of F2, F3 and F4 stage patients were significantly higher than those of nonsignificant liver fibrosis patients (METAVIR F0-F1), but there were no significant differences among F2, F3 and F4 stage patients. Serum HBcrAg (OR, 2.18; 95% confidence interval [CI], 1.51-3.16), albumin (ALB) (OR, 0.60; 95% CI, 0.41-0.87), prothrombin activity (PTA) (OR, 0.58; 95% CI, 0.40-0.83) and platelet (PLT) counts (OR, 0.38; 95% CI, 0.25-0.57) were associated with significant liver fibrosis (METAVIR F2-F4). The serum HBcrAg value enabled the correct identification of patients with significant fibrosis, with an area under the receiver operating characteristic curve of 0.81 (95% CI, 0.75-0.88). The APRI, FIB-4 index and ALBI score can identify significant liver fibrosis with an area under the ROC curve of 0.74 (95% CI, 0.66-0.81), 0.73 (95% CI, 0.65-0.80) and 0.63 (95% CI, 0.55-0.72), respectively. Compared with these three indexes, the accuracy rate of diagnosis of significant fibrosis based on HBcrAg was higher than that of the FIB-4 index (p = 0.0479) and ALBI score (p = 0.0030). HBcrAg, ALB, PTA serum levels and PLT counts were associated with significant liver fibrosis in treatment-naive chronic HBV infection patients. HBcrAg serum levels enabled the correct identification of patients with significant fibrosis (METAVIR F2-F4), and HBcrAg was more effective than the FIB-4 index and ALBI score.

Abstract
OBJECTIVE To assess predictive ability of hepatitis B virus (HBV) markers and genome mutations for spontaneous hepatitis B e antigen (HBeAg) seroconversion. METHODS A total of 113 chronic hepatitis B (CHB) patients were followed up for 76 weeks without antiviral treatment. Baseline basal core promoter (BCP) and precore mutations were detected and serum hepatitis B surface antigen (HBsAg), HBeAg, hepatitis B core-related antigen (HBcrAg) and HBV DNA levels were serially quantified. RESULTS Eighteen patients experienced spontaneous HBeAg seroconversion (Group A), and the left 95 patients did not experience spontaneous HBeAg seroconversion (Group B). At week 28, HBsAg (P=0.03) and HBcrAg (P=0.01) levels were significantly different between Group A and B. Reduced HBsAg (P=0.02) and HBcrAg (P<0.01) levels from baseline to week 28 were significantly different between two groups. Multivariate logistic regression showed that lower HBcrAg (OR=1.02, P=0.03) levels at week 28, and HBcrAg levels with sharp decrease at week 28 (OR=0.19, P=0.02) were related with spontaneous HBeAg seroconversion. The areas under the receiver operating characteristic curve (AUROC) showed that reduction in HBcrAg levels from baseline to week 28 (0.93, P=0.001, 95% CI: 0.74-1.08) have excellent prediction value. The mutation frequencies of A1574T (51.11% vs 18.18%, P=0.001), G1862A (30.00% vs 13.03%, P=0.001), G1896A (27.22% vs 5.45%, P=0.001) and C1913G (32.78% vs 12.73%, P=0.001) in Group A were significantly higher than Group B. CONCLUSIONS Baseline A1574T, G1862A, G1896A and C1913G mutations and HBcrAg levels with sharp decrease at week 28 were associated with spontaneous HBeAg seroconversion.

Abstract
The hepatitis B core-related antigen (HBcrAg) is an unprecedented novel HBV biomarker that plays an essential role in reflecting covalently closed circular DNA (cccDNA) in chronic hepatitis B (CHB) because its levels correlate with intrahepatic cccDNA and serum HBV DNA. In this review, we describe the clinical application of serum HBcrAg in CHB patients, with a particular focus on new therapies targeting intrahepatic HBV replication. (1) HBcrAg can be detected in clinical cases where serum HBV DNA is undetectable during anti-HBV therapy. (2) A highly sensitive HBcrAg assay (iTACT-HBcrAg) may be useful for monitoring HBV reactivation, as an alternative to HBV DNA. (3) Decreased HBcrAg levels have been significantly associated with promising outcomes in CHB patients, reducing the risk of progression or recurrence of hepatocellular carcinoma. Additionally, we focus on and discuss several drugs in development that target HBV replication, and monitoring HBcrAg may be useful for determining the therapeutic efficacies of such novel drugs. In conclusion, HBcrAg, especially when measured by the recently developed iTACT-HBcrAg assay, may be the most appropriate surrogate marker, over other HBV biomarkers, to predict disease progression and treatment response in CHB patients.

Abstract
Objective It remains unknown how to stratify the risk of clinical relapse of chronic hepatitis B (CHB) patients after stopping nucleos(t)ide analogs (NAs) antiviral therapy. Methods The current post hoc analysis included 122 non-cirrhotic patients with chronic hepatitis B virus infection who were positive for hepatitis B envelope antigen (HBeAg) and discontinued long-term NA therapy after achieving HBeAg seroconversion for a median of 2.5 years. Post hoc analysis of end-of-treatment (EOT) hepatitis B core-related antigen (HBcrAg) levels was performed using a chemiluminescent enzyme immunoassay. Results A total of 78/122 (63.9%) patients experienced sustained response after NAs cessation, and 44/122 (36.1%) patients experienced clinical relapse. In multivariate analysis, EOT HBcrAg (hazard ratio [HR] = 2.105 95% CI: 1.440–3.077, p < 0.001), hepatitis B surface antigen (HBsAg) ≥100 IU/mL (HR = 4.406, 95% CI 1.567–12.389, p = 0.005) and age (HR = 1.051, 95% CI: 1.010–1.093, p = 0.049) were independently associated with clinical relapse. A cut-off value of 4.0 log10 U/mL of HBcrAg was defined by maximized Youden’s index. An EOT HBcrAg level of ≥4.0 log10 U/mL was associated with higher risks of clinical relapse (65.8% vs 23.2%, p<0.001) and HBeAg reversion (27.5% vs 1.6%, p < 0.001). In majority of patients (n = 91) who had a high EOT HBsAg level (≥100 IU/mL), serum HBcrAg level could further discriminate patients at low risk of clinical relapse. Patients with an HBcrAg level ≥4.0 log10 U/mL had significantly higher cumulative incidence rates of clinical relapse (78.1% vs 29.4%, p < 0.001) and HBeAg reversion (29.4% vs 0%, p < 0.001). Conclusion Serum EOT HBcrAg level can be a predictor of off-treatment relapse in patients with CHB. An HBcrAg level of 4.0 log10 U/mL may identify patients at high risk of clinical relapse after treatment cessation.

Abstract
While the preS1 region of the large hepatitis B surface protein plays an essential role in hepatitis B virus (HBV) infection, the effect of preS1 on liver fibrosis and hepatocarcinogenesis in chronic hepatitis B (CHB) patients is not well known. In this study, we measured serum preS1 levels by chemiluminescent immunoassay technology in 690 CHB patients and evaluated the correlation between serum preS1 levels and HBV, liver function markers and liver inflammation, fibrosis assessed by histological findings. Predictive factors for hepatocellular carcinoma (HCC) development in patients who had no previous history of HCC at the time of preS1 level measurement were also analysed. Median hepatitis B surface antigen (HBsAg) and preS1 levels were 3.08 log IU/mL and 98 ng/mL, respectively. PreS1 values were significantly correlated with serum HBsAg (p <0.001), hepatitis B core-related antigen (HBcrAg) (p <0.001) and HBV DNA levels (p <0.01). PreS1 values were also significantly correlated with serum alanine aminotransferase levels (p <0.001) and were significantly higher in patients who had higher grading of liver inflammatory activity (p <0.05). HBsAg level was correlated, but preS1/HBsAg ratio reflected liver fibrosis staging more directly than HBsAg alone. Multivariate analysis identified age ≥53 years (hazard ratio [HR], 18.360 for <53 years; p = 0.021) and preS1/HBsAg ratio ≥0.12 (HR, 6.205 for <0.12; p = 0.040) as significant and independent factors for HCC development in CHB patients. The preS1/HBsAg ratio directly reflects liver fibrosis, and the ratio might be a predictive marker for HCC development in CHB patients.

Abstract
This study investigated the ability of hepatitis B core-related antigen (HBcrAg) to predict hepatitis B virus (HBV) relapse in HBeAg-negative patients after cessation of entecavir therapy. A total of 301 HBeAg-negative patients without cirrhosis who had stopped entecavir therapy for at least 12 months were recruited. All patients fulfilled the stopping criteria proposed by the APASL 2012 guidelines. The five-year cumulative rates of virological relapse, clinical relapse and HBsAg loss were 71.6%, 57.3% and 18.7%, respectively. Serum HBsAg at end of treatment (EOT) was an independent predictor of virological relapse, clinical relapse and HBsAg loss; an EOT HBsAg of 150 IU/ml was the optimal cut-off value. The 5-year virological relapse rates for patients with <150 and ≥150 IU/ml HBsAg at EOT were 43.3% and 82.2% (p < 0.001), clinical relapse rates were 32.3% and 66.3% (p < 0.001), and HBsAg loss rates were 46.1% and 5.2% (p < 0.001), respectively. A baseline HBcrAg of 4 IU/ml was the optimal cut-off value for predicting HBV relapse. Among patients with an EOT HBsAg <150 IU/ml, the five-year virological relapse rates for patients with baseline HBcrAg levels ≤4 and >4 log U/ml were 27.9% and 59.1% (p = 0.006) and the clinical relapse rates were 18% and 48.1% (p = 0.014), respectively. EOT HBcrAg was not a significant predictor of virological or clinical relapse after cessation of entecavir. In conclusion, the combination of an EOT HBsAg of 150 IU/ml and baseline HBcrAg of 4 log U/ml can effectively predict the risk of HBV relapse after stopping entecavir therapy.

Abstract
Limited access to nucleic acid testing (NAT) to quantify HBV DNA levels, an essential tool to determine anti-HBV treatment eligibility, represents a significant barrier to scale up HBV diagnostic services in resource-limited countries. Hepatitis B core-related antigen (HBcrAg) has the potential to become an affordable alternative because of its low cost (US$ <15/assay) and strong correlation with HBV DNA levels in treatment-naïve patients. However, the current assay requires plasma or serum. To further facilitate its application to decentralized settings, we developed and evaluated a standardized procedure to quantify HBcrAg using dried blood spots as a tool to diagnose HBV-infected people with high viraemia. We evaluated the following elution method optimized to quantify HBcrAg: suspension of a punched blood-soaked disc (11 mm) of Whatman 903 Protein Saver Card in 450 µL of PBS 0.05% Tween 20, followed by an incubation for 4 h at room temperature and a centrifugation at 10,000 g for 10 minutes. 150 µL of DBS eluate was used to quantify HBcrAg using chemiluminescent enzyme immunoassay (LUMIPULSE® G600II, Fujirebio). The limit of detection of dried blood spot HBcrAg in relation with HBV DNA levels was 19,115 IU/mL across the five major HBV genotypes (A/B/C/D/E). A strong linear correlation was confirmed between dried blood spot HBcrAg and HBV DNA levels (r = 0.94, p < 0.0001) in samples with high viral loads (range: 3.7-7.0 log IU/mL). The coefficient of variation ranged between 4.0-11.2% for repeatability and 3.9-12.2% for reproducibility. Analytical specificity was 100% (95% CI: 83.9-100%) in HBV-negative samples. Using our elution method, it may be possible to identify HBV-infected patients with high viraemia who need antiviral therapy using dried blood spot and HBcrAg. A large-scale clinical validation is warranted in resource-limited countries.

Abstract
AIMS Hepatitis B surface antigen (HBsAg) seroclearance indicates a "functional cure" in chronic hepatitis B (CHB) virus infection. However, several cases of hepatocellular carcinoma (HCC) development have been reported after HBsAg seroclearance. We evaluated the potential of HBsAg and hepatitis B core-related antigen (HBcrAg), measured by the ultra-highly sensitive assays, in cases with HCC development after HBsAg seroclearance. METHODS We enrolled 17 patients with CHB who achieved HBsAg seroclearance, defined by the conventional assay using Architect HBsAg QT kit (five HCC patients and 12 non-HCC patients). HBsAg and HBcrAg were measured in their stored serum samples using ultra-highly sensitive assays featuring "immunoassay for total antigen including complex via pretreatment (iTACT)" technology. RESULTS All five patients who developed HCC were positive for HBsAg or HBcrAg by iTACT-HBsAg or iTACT-HBcrAg at all follow-up points. HBcrAg levels in the HCC group, using iTACT-HBcrAg, were significantly higher than those in the non-HCC group at HBsAg seroclearance (3.6 LogU/ml (2.8-4.2) versus 2.6 (<2.1-3.8), p = 0.020). The best cutoff value of iTACT-HBcrAg for predicting HCC development was 2.7 LogU/ml by receiver operating characteristic curve analysis. The prevalence of HBcrAg ≥2.7 in the HCC group was significantly higher than that in non-HCC group (100% [5/5] versus 33% [4/12], p = 0.029). CONCLUSIONS Residual low viral antigen might predict HCC development even if HBsAg seroclearance was achieved according to a conventional assay. The results suggest that iTACT assays of HBsAg and HBcrAg would be useful for monitoring CHB patients.

Abstract
BACKGROUND The aim of the current study was to describe the kinetics of quantified hepatitis B core-related antigen (qHBcrAg) and quantified anti-hepatitis B core antibody (qAnti-HBc) during tenofovir (TDF) treatment and assess their ability to predict hepatitis B e antigen (HBeAg) seroclearance in patients coinfected with human immunodeficiency virus (HIV) and hepatitis B virus. METHODS Serum qHBcrAg, qAnti-HBc, and hepatitis B virus DNA were obtained at TDF initiation and every 6-12 months. The on-treatment kinetics of qHBcrAg (ΔqHBcrAg) and qAnti-HBc (ΔqAnti-HBc) were estimated using mixed-effect linear regression. Hazard ratios (HRs) assessing the association between markers and HBeAg seroclearance were calculated using proportional hazards regression, and the sensitivity (Se) and specificity (Sp) of marker levels in predicting HBeAg seroclearance were assessed using time-dependent receiving operating characteristic curves. RESULTS During a median of 4.6 years, the cumulative incidences of hepatitis B surface antigen and HBeAg seroclearance were 3.2% (n = 5 of 158) and 27.4% (n = 26 of 95), respectively. ΔqHBcrAg was biphasic in HBeAg-positive patients (-0.051 and -0.011 log10 U/mL/mo during ≤18 and >18 months, respectively) and monophasic in HBeAg-negative patients. ΔqAnti-HBc was monophasic regardless of HBeAg status. In HBeAg-positive patients, baseline qHBcrAg and qAnti-HBc levels were associated with HBeAg seroclearance (adjusted HR, 0.48/log10 U/mL [95% confidence interval, .33-.70] and unadjusted HR, 1.49/log10 Paul Ehrlich Institute units/mL [1.08-2.07], respectively). Cutoffs with the highest accuracy in predicting HBeAg seroclearance at 36 months were qHBcrAg <6.5 log10 U/mL at month 24 (Se, 1; Sp, 0.58) and baseline qAnti-HBc ≥4.1 log10 Paul Ehrlich Institute units/mL (Se, 0.42; Sp, 0.81). CONCLUSIONS In coinfected patients undergoing TDF, qHBcrAg/qAnti-HBc could be of use in monitoring HBeAg seroclearance.

Abstract
Patients with chronic hepatitis B virus (HBV) infection are at risk of developing hepatocellular carcinoma (HCC), and serum markers reflecting viral replication are potential predictors for HCC development. Besides the levels of serum HBV DNA and hepatitis B surface antigen (HBsAg), hepatitis B core-related antigen (HBcrAg) quantification is an emerging serological marker for viral replication. Unlike HBV DNA and HBsAg, HBcrAg is a covalently closed circular DNA-derived protein marker, consisting of hepatitis B e antigen (HBeAg), p22cr, and hepatitis B core antigen. In treatment-naïve HBV patients, higher HBcrAg levels are shown to be associated with an increased risk of HCC in several studies. More importantly, HBcrAg may complement HBV DNA level to predict HCC development. For example, an Asian treatment-naïve cohort study’s data showed that HBcrAg level of 4 log U/mL was effective to stratify HCC risk in HBeAg-negative patients with intermediate viral loads, who may not need antiviral therapy because of the low to moderate risk of HCC. In patients receiving prolonged nucleos(t)ide analogue with profound viral suppression, most data indicated that HBV DNA and HBsAg levels no longer serve as HCC predictors. However, several studies suggested on-treatment HBcrAg levels may remain as an HCC predictor. In summary, HBcrAg level can be a useful biomarker for treatment-naïve patients, but its value in on-treatment patients needs validation. The next challenge is how to combine HBcrAg with the other viral markers to construct a better HCC prediction model, optimizing the management of HBV patients.

Abstract
Current therapies rarely cure chronic hepatitis B virus (HBV) infection due to the persistence of the viral episome, the covalently closed circular DNA (cccDNA), in hepatocytes. The hepatitis B virus core-related antigen (HBcrAg), a mixture of the viral precore/core gene products, has emerged as one potential marker to monitor the levels and activities of intrahepatic cccDNA. In this study, a comprehensive characterization of precore/core gene products revealed that HBcrAg components included the classical hepatitis B virus core antigen (HBc) and e antigen (HBeAg) and, additionally, the precore-related antigen, PreC, retaining the N-terminal signal peptide. Both HBeAg and PreC antigens displayed heterogeneous proteolytic processing at their C termini resulting in multiple species, which varied with viral genotypes. HBeAg was the predominant form of HBcrAg in HBeAg-positive patients. Positive correlations were found between HBcrAg and PreC, between HBcrAg and HBeAg, and between PreC and HBeAg but not between HBcrAg and HBc. Serum HBeAg and PreC shared similar buoyant density and size distributions, and both displayed density and size heterogeneity. HBc, but not HBeAg or PreC antigen, was found as the main component of capsids in DNA-containing or empty virions. Neither HBeAg nor PreC protein was able to form capsids in cells or in vitro under physiological conditions. In conclusion, our study provides important new quantitative information on levels of each component of precore/core gene products as well as their biochemical and biophysical characteristics, implying that each component may have distinct functions and applications in reflecting intrahepatic viral activities.IMPORTANCE Chronic hepatitis B virus (HBV) infection afflicts approximately 257 million people, who are at high risk of progressing to chronic liver diseases, including fibrosis, cirrhosis, and hepatocellular carcinoma. Current therapies rarely achieve cure of HBV infection due to the persistence of the HBV episome, the covalently closed circular DNA (cccDNA), in the nuclei of infected hepatocytes. Peripheral markers of cccDNA levels and transcriptional activities are urgently required to guide antiviral therapy and drug development. Serum hepatitis B core-related antigen (HBcrAg) is one such emerging peripheral marker. We have characterized the components of HBcrAg in HBV-infected patients as well as in cell cultures. Our results provide important new quantitative information on levels of each HBcrAg component, as well as their biochemical and biophysical characteristics. Our findings suggest that each HBcrAg component may have distinct functions and applications in reflecting intrahepatic viral activities.

Abstract
OBJECTIVES Many studies have investigated the utility of hepatitis B virus (HBV) serological markers in HBV-infected patients. However, only a few studies have examined HBV serological markers in HBV-human immunodeficiency virus (HIV) co-infected patients. Here, we conducted a cross-sectional study to evaluate correlations of HBV serological markers in treatment-naïve HBV mono-infected patients and HBV-HIV co-infected patients. METHODS HBsAg, HBV DNA, HBV RNA, and HBcrAg were quantified in 51 HBV mono-infected patients and 33 HBV-HIV co-infected patients recruited at Tianjin Second People's Hospital from 2016 to 2019. RESULTS There was no significant difference in serum levels of HBV DNA (P = 0.056), HBV RNA (P = 0.387), HBcrAg (P = 0.714) and HBsAg (P = 0.165) between the patient groups. In HBV mono-infected patients, strong positive correlations were confirmed between HBV RNA and HBV DNA (r=0.620, P < 0.01), HBcrAg and HBV DNA (r=0.802, P < 0.001), and HBcrAg and HBV RNA (r=0.727, P < 0.01). In HBV-HIV co-infected patients, serum HBsAg was very strongly correlated with HBcrAg (r=0.838, P < 0.001). In HBeAg-positive HBV mono-infected patients, all HBV serological markers correlated with each other, whereas only HBV RNA correlated with HBcrAg in HBeAg-negative HBV mono-infected patients (r=0.688, P = 0.007). In HBeAg-positive HBV-HIV co-infected patients, only HBsAg correlated with HBcrAg (r=0.725, P<0.001), whereas HBcrAg and HBV RNA correlated with each other in HBeAg-negative patients (r = 0.683, P=0.010). Moreover, CD4 T-cell counts were not significantly associated with HBsAg, HBV DNA, HBV RNA, and HBcrAg levels. CONCLUSION Compared with HBsAg and HBV DNA, which are widely used in clinical settings, our study confirmed that new HBV serological markers, such as HBV RNA and HBcrAg, have some utility in HBV mono-infected patients and HBV-HIV co-infected patients for monitoring the progression of liver disease.

Abstract
Background Quantitative hepatitis B core-related antigen (qHBcrAg) or antihepatitis B core antibody (qAnti-HBc) could be useful in monitoring liver fibrosis evolution during chronic hepatitis B virus (HBV) infection, yet it has not been assessed in human immunodeficiency virus (HIV)-HBV-coinfected patients undergoing treatment with tenofovir (TDF). Methods One hundred fifty-four HIV-HBV-infected patients initiating a TDF-containing antiretroviral regimen were prospectively followed. The qHBcrAg and qAnti-HBc and liver fibrosis assessment were collected every 6–12 months during TDF. Hazard ratios (HRs) assessing the association between qHBcrAg/qAnti-HBc and transitions from none/mild/significant fibrosis to advanced fibrosis/cirrhosis (progression) and from advanced fibrosis/cirrhosis to none/mild/significant fibrosis (regression) were estimated using a time-homogeneous Markov model. Results At baseline, advanced liver fibrosis/cirrhosis was observed in 40 (26%) patients. During a median follow-up of 48 months (interquartile range, 31–90), 38 transitions of progression (IR = 7/100 person-years) and 34 transitions of regression (IR = 6/100 person-years) were observed. Baseline levels of qHBcrAg and qAnti-HBc were not associated with liver fibrosis progression (adjusted-HR per log10 U/mL = 1.07, 95% confidence interval [CI] = 0.93–1.24; adjusted-HR per log10 Paul-Ehrlich-Institute [PEI] U/mL = 0.85, 95% CI = 0.70–1.04, respectively) or regression (adjusted-HR per log10 U/mL = 1.17, 95% CI = 0.95–1.46; adjusted-HR per log10 PEI U/mL = 0.97, 95% CI = 0.78–1.22, respectively) after adjusting for age, gender, duration of antiretroviral therapy, protease inhibitor-containing antiretroviral therapy, and CD4+/CD8+ ratio. Nevertheless, changes from the previous visit of qAnti-HBc levels were associated with liver fibrosis regression (adjusted-HR per log10 PEIU/mL change = 5.46, 95% CI = 1.56–19.16). Conclusions Baseline qHBcrAg and qAnti-HBc levels are not associated with liver fibrosis evolution in TDF-treated HIV-HBV coinfected patients. The link between changes in qAnti-HBc levels during follow-up and liver fibrosis regression merits further study.

Abstract
BACKGROUND To eliminate hepatitis B virus (HBV) infection, it is essential to scale up testing and treatment. However, conventional tools to assess treatment eligibility, particularly nucleic acid testing (NAT) to quantify HBV DNA, are hardly available and affordable in resource-limited countries. We therefore assessed the performance of a novel immunoassay, hepatitis B core-related antigen (HBcrAg), as an inexpensive (US$ <15/assay) alternative to NAT to diagnose clinically important HBV DNA thresholds (≥2000, ≥20 000, and ≥200 000 IU/mL) and to select patients for antiviral therapy in Africa. METHODS Using a well-characterized cohort of treatment-naive patients with chronic HBV infection in The Gambia, we evaluated the accuracy of serum HBcrAg to diagnose HBV DNA levels and to indicate treatment eligibility determined by the American Association for the Study of Liver Diseases, based on reference tests (HBV DNA, hepatitis B e antigen, alanine aminotransferase, liver histopathology, and/or FibroScan). RESULTS A total of 284 treatment-naive patients were included in the analysis. The area under the receiver operating characteristic curve (AUROC), sensitivity, and specificity of serum HBcrAg were 0.88 (95% confidence interval [CI], .82-.93), 83.3%, and 83.9%, respectively, to diagnose HBV DNA ≥2000 IU/mL; and 0.94 (95% CI, .88-.99), 91.4%, and 93.2% for ≥200 000 IU/mL. A simplified treatment algorithm using HBcrAg without HBV DNA showed high AUROC (0.91 [95% CI, .88-.95]) with a sensitivity of 96.6% and specificity of 85.8%. CONCLUSIONS HBcrAg might be an accurate alternative to HBV DNA quantification as a simple and inexpensive tool to identify HBV-infected patients in need of antiviral therapy in low- and middle-income countries.

Abstract
Reliable predictors of outcomes after treatment discontinuation in HBeAg-negative chronic hepatitis B (CHB) patients have not been established. We investigated the role of hepatitis B surface antigen (HBsAg), interferon-inducible protein-10 (IP10) and hepatitis B core-related antigen (HBcrAg) serum levels as predictors of HBsAg loss, relapse and retreatment in noncirrhotic HBeAg-negative CHB patients who discontinued long-term antiviral therapy. All HBsAg-positive (n = 57) patients of the prospective DARING-B study were included and followed monthly for 3 months, every 2/3 months until month-12 and every 3/6 months thereafter. HBsAg, IP10 and HBcrAg levels were measured by enzyme immunoassays, and SCALE-B score was calculated. Twelve patients achieved HBsAg loss before retreatment with 18-month cumulative incidence of 25%. Independent predictors of HBsAg loss were baseline HBsAg and month-1 IP10 levels. Of 10 patients with baseline HBsAg ≤100 IU/mL, 70% cleared HBsAg and 10% required retreatment. Of 23 patients with baseline HBsAg >1000 IU/mL, 4% cleared HBsAg and 43% required retreatment. Of 24 patients with intermediate baseline HBsAg (100-1000 IU/mL), 17% cleared HBsAg and 21% required retreatment; in this subgroup, month-1 IP10 was significantly associated with HBsAg loss, which occurred in 30% and 7% of cases with IP10 >150 and ≤150 pg/mL, respectively. Baseline HBcrAg was undetectable in all patients who cleared HBsAg and was associated with retreatment. SCALE-B was associated with HBsAg loss but not with relapse or retreatment. In conclusion, HBsAg, IP10 and HBcrAg serum levels can be useful for the decisions and management of treatment discontinuation in noncirrhotic Caucasian patients with HBeAg-negative CHB.

Abstract
Hepatitis B core-related antigen (HBcrAg) is a novel serological marker for hepatitis B virus infection. Its clinical significance after HBeAg seroconversion has not been defined. We aimed to determine the relationship between HBcrAg levels after spontaneous HBeAg seroconversion and hepatocellular carcinoma (HCC). A total of 207 chronic hepatitis B patients with documented time of HBeAg seroconversion were enrolled. HBcrAg and HBsAg were checked within 3 years (as baseline), at 5 and 10 years after HBeAg seroconversion. HBV DNA was measured at the baseline. Multivariate Cox regression model was used to investigate the predictors for HCC development. The median follow-up time was 13.1 (11.8-15.5) years. Fourteen patients developed HCC (15-year cumulative incidence: 7%). The median level of HBcrAg at baseline was significantly higher in patients who developed HCC when compared with patients without HCC (5.68 vs 4.78 log U/ml, respectively; P = .003). Cox proportional hazards model indicated that age of HBeAg seroconversion older than 40 years (hazard ratio (HR): 4.60; P = .049), presence of baseline cirrhosis (HR: 6.23; P = .003) and a higher baseline HBcrAg (HR: 1.75; P = .032) were independently associated with HCC development. A cut-off value of baseline HBcrAg level ≥5.21 log U/mL yielded an AUROC of 0.74 with a negative predictive value of 97.7%. High HBcrAg levels within 3 years after HBeAg seroconversion were independently associated with the development of HCC in chronic hepatitis B patients.

Abstract
Hepatitis B e antigen (HBeAg) seroconversion experienced during nucleo(s)tide analogue (NUC) therapy is often not sustained. We aimed to study whether hepatitis B core-related antigen (HBcrAg) levels predict sustained HBeAg seroconversion in patients treated with NUCs. We studied HBeAg-positive patients treated with NUCs for at least 6 months. We quantified HBcrAg at baseline and at the time of HBeAg seroconversion and studied the relationship with HBeAg seroconversion and subsequent relapse. HBcrAg was quantified at baseline in 196 patients; levels varied significantly by HBV genotype and correlated with HBsAg, HBV DNA and HBeAg. Baseline HBcrAg levels were lower in patients who achieved HBeAg seroconversion than in those who did not; the unadjusted hazard ratio (HR) was 0.802 (95% CI: 0.656-0.980, P = 0.031); and this association was not sustained in multivariate analysis. HBcrAg remained detectable in all patients at the time of HBeAg seroconversion. Higher HBcrAg at the time of seroconversion was an independent predictor of relapse (adjusted HR: 1.855 (95% CI: 1.099-3.133, P = 0.021), and none of the patients with HBcrAg < 4.90 log U/mL experienced relapse. Baseline HBcrAg is not an independent predictor of HBeAg seroconversion during NUC therapy. HBcrAg remains detectable in patients after HBeAg seroconversion. Patients with lower levels at the time of seroconversion have a higher probability of sustained HBeAg seroconversion.

Abstract
Hepatitis B core-related antigen (HBcrAg) has been proposed as a new marker of hepatitis B virus (HBV) replication. We analyzed HBcrAg dynamics in 15 heart transplant recipients with active or prior HBV infection and correlated it with quantitative (QT)-HBsAg and HBV-DNA pre- and post-transplant. Serum HBcrAg was detected in HBsAg/HBV-DNA-positive subjects but not in recipients with past HBV infection. HBcrAg levels correlated with QT-HBsAg in pre- and post-transplant samples. In prior HBV infection, HBcrAg levels were unrelated to HBV-DNA positivity. In heart transplant recipients with prior HBV infection, HBcrAg does not correlate with viral replication and cannot be applied to detect HBV reactivation during follow-up.

Abstract
The correlation between serum HBcrAg and HBV RNA is unclear, and correlations of intrahepatic cccDNA with HBcrAg, HBV RNA and HBsAg are rarely reported in the same cohort. This study aimed to assess the correlation of HBcrAg with HBV RNA and HBsAg, and investigate whether serum HBcrAg is superior to serum HBV RNA and HBsAg in reflecting intrahepatic HBV cccDNA in HBeAg-positive and HBeAg-negative CHB patients. In this study, 85 HBeAg-positive and 25 HBeAg-negative patients who have never received antiviral therapy were included. Among HBeAg-positive patients, HBcrAg was correlated positively with HBsAg (r = 0.564, P < 0.001) and HBV RNA (r = 0.445, P < 0.001), and HBV RNA was also correlated positively with HBsAg (r = 0.323, P = 0.003). Among HBeAg-negative patients, no significant correlation was observed between HBcrAg, HBsAg and HBV RNA. By multivariable linear regression, HBcrAg (β = -0.563, P < 0.001), HBsAg (β = -0.328, P < 0.001) and HBV RNA (β = 0.180, P = 0.003) were all associated with cccDNA levels among HBeAg-positive patients, but only serum HBcrAg was associated with cccDNA level (β = 0.774, P = 0.000) among HBeAg-negative patients. HBcrAg was better correlated with cccDNA as compared to HBsAg and HBV RNA, irrespective of HBeAg status. Among HBeAg-positive patients, though HBcrAg level was influenced by hepatic inflammatory activity and HBV DNA levels, the good correlations of HBcrAg with cccDNA persisted after stratification by inflammatory activity and HBV DNA levels. In conclusion, correlations of serum HBcrAg, HBV RNA and HBsAg levels differ significantly between HBeAg-positive and HBeAg-negative patients, but serum HbcrAg correlates with cccDNA levels better than HBV RNA and HBsAg, irrespective of HBeAg status.

Abstract
AIM We sought to create a prediction model for intrahepatic covalently closed circular DNA (IH-cccDNA) level in chronic hepatitis B (CHB) patients and to validate the model's predictive accuracy. METHODS Patients who did not receive previous nucleoside analogue (NA) therapy were assigned to the training cohort (n = 57), and those who received previous NA therapy were assigned to the validation cohort (n = 69). Factors linked to IH-cccDNA levels in the training cohort were analyzed and a formula to predict IH-cccDNA levels was constructed. Next, the reproducibility of that formula was assessed. RESULTS In the multivariate analysis for the prediction of IH-cccDNA level in the training cohort, fasting blood sugar (FBS) (P = 0.0227), hepatitis B e antigen (HBeAg) (P = 0.0067) and log10 (HB surface antigen [HBsAg]) (P = 0.0497) were significant, whereas HB core-related antigen (HBcrAg) tended to be significant (P = 0.0562). The formula was constructed and named the FBS-cres score based on the variables used (FBS, HBcrAg, HBeAg, and HBsAg). The FBS-cres score was calculated as: 3.1686 - (0.0148 × FBS) + (0.1982 × HBcrAg) + (0.0008168 × HBeAg) + (0.1761 × log10 (HBsAg)). In the training cohort, a significant correlation was noted between HBcrAg and IH-cccDNA levels (P < 0.0001, r = 0.67), whereas the FBS-cres score was more closely correlated to IH-cccDNA level (P < 0.0001, r = 0.81). In the validation cohort, significant correlation was found between HBcrAg and IH-cccDNA levels (P = 0.0012, r = 0.38), whereas the FBS-cres score was more closely linked to IH-cccDNA levels (P < 0.0001, r = 0.51). Similar tendencies were observed in all subgroup analyses. CONCLUSION Our proposed model for the prediction of IH-cccDNA level could be helpful in CHB patients.

Abstract
The purpose of this study was to explore the correlations of serum hepatitis B core-related antigen (HBcrAg) with intrahepatic Hepatitis B virus (HBV) covalently closed circular DNA (cccDNA) and HBV total DNA in hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) patients. Serum HBcrAg and other parameters, including HBV DNA, HBV RNA, HBeAg, hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were quantitatively measured at baseline and follow-up time points. Intrahepatic HBV cccDNA and total DNA were quantitatively detected at baseline and 96 weeks. Grading of liver necroinflammation and staging of hepatic fibrosis were assessed at baseline and 96 weeks. Correlations between serum HBcrAg and other parameters were analyzed by Pearson's correlation analysis. The results showed that pretreatment HBcrAg correlated significantly with HBV total DNA levels (r = 0.328, P = 0.003) in 82 CHB patients, and, after removing three outliers, with intrahepatic HBV cccDNA (r = 0.323, P = 0.004; n = 79). Serum HBcrAg correlated better with HBV cccDNA in patients with lower levels of serum HBV DNA (stratified by 7 log IU/ml of HBV DNA; r = 0.656, P = 0.003 versus r = -0.02, P = 0.866). Significant inverse correlations were found between HBcrAg and grade of liver necroinflammation (r = -0.245, P = 0.037), stage of hepatic fibrosis (r = -0.360, P = 0.002) at baseline. Serum HBcrAg presented significant correlation with intrahepatic HBV cccDNA in patients with HBeAg seroconversion at 96 weeks (r = 0.622, P = 0.006). The decrease in HBcrAg showed significant correlation with the decrease in HBV cccDNA after 96-week NA therapy (r = 0.282, P = 0.043). Serum HBcrAg also correlated significantly with other serum markers at baseline and 96 weeks of NA therapy. In conclusion, baseline HBcrAg and its decreased value were significantly correlated with the corresponding intrahepatic HBV cccDNA.

Abstract
HBeAg seroconversion marks an important spontaneous change and treatment end-point for HBeAg-positive patients and is a pre-requisite for HBsAg loss or functional cure. In this retrospective analysis, we aimed to identify predictors of seroconversion using serum quantitative HBsAg and HBcrAg, in HBeAg-positive patients treated with nucleos(t)ide analogues (NA). Data and samples from 118 HBeAg-positive adults (genotypes A-G) started on NA between Jan 2005 and Sept 2016 were retrospectively analysed at several time-points. The predictive power of on-treatment levels of HBsAg and HBcrAg was determined using receiver operating curve (ROC) analysis and cut-off values determined by maximized Youden's index. About 36.4% of patients achieved HBeAg seroconversion after a median of 39 months' treatment. On treatment kinetics of HBV DNA, HBsAg and HBcrAg differed between HBeAg seroconverters and nonseroconverters. A combination of HBsAg and HBcrAg had the greatest predictive value for HBeAg seroconversion: at 6 months, HBsAg of 3.9 log10 IU/mL and HBcrAg of 5.7 log10 U/mL had a sensitivity of 71.4%, specificity of 79.5%, positive predictive value (PPV) of 65.2% and negative predictive value (NPV) of 83.8%, with AUROC of 0.769 (0.668, 0.869; 95%CI), and at 12 months, HBsAg 3.8 log10 IU/mL and HBcrAg 5.5 log10 U/mL had a sensitivity of 73.7%, specificity of 79.5%, PPV of 63.6% and NPV of 86.1%, with AUROC 0.807 (0.713, 0.901; 95% CI). In conclusion, our results may be used to identify patients who are unlikely to achieve treatment end-points, which will be important as the future management of chronic hepatitis B looks to therapies that offer functional cure.

Abstract
We examined the relationship between hepatitis B surface and core-related antigens (HBsAg, HBcrAg) and hepatocellular carcinoma (HCC) development in patients with undetectable serum HBV DNA receiving nucleos(t)ide analogue (NA). Seventy-six HBV carriers with undetectable HBV DNA (<20 IU/mL) who subsequently developed HCC were compared with 152 matched controls. Clinical and laboratory parameters (including novel assays to measure linearized HBsAg [HQ-HBsAg] and HBcrAg) were analysed. There were no significant differences in HBsAg/HQ-HBsAg levels between the two groups. There was a significant difference in the median values of both pre- and post-NA HBcrAg levels between the HCC and control groups (pre-treatment: 279.0 vs 35.4 kU/mL, P=.005; post-treatment: 10.2 vs 1.7 kU/mL, P=.005, respectively). For the whole HCC group, a cut-off value of post-treatment HBcrAg level ≥7.8 kU/mL yielded an area under receiver operating curve (AUROC) of 0.61 with a negative predictive value (NPV) of 77.0%. The OR of HCC development was 3.27. For noncirrhotic patients, the median values of post-treatment HBcrAg level of HCC group and controls were 10.2 and 1.0 kU/mL, respectively (P=.001). A cut-off value of HBcrAg level ≥7.9 kU/mL yielded an AUROC of 0.70 with a NPV of 80.6%. The OR of HCC development was 5.95. A higher pre- and post-NA treatment HBcrAg level (but not HBsAg) was associated with an increased risk of HCC development in patients achieving undetectable serum HBV DNA while on NA therapy. HBcrAg may serve as a novel risk marker for HCC in this group of patients.

Abstract
AIM The aim of this study was to evaluate the correlation between hepatitis B core-related antigen (HBcrAg) and hepatitis B virus (HBV) DNA and hepatitis B surface antigen (HBsAg) levels, and to investigate HBcrAg kinetics during nucleos(t)ide analogue (NA) or pegylated-interferon (PEG-IFN)-α treatment in a cohort of chronic hepatitis B (CHB) genotype D patients. METHODS One hundred thirty eight sequential serum samples were collected from 28 hepatitis B e antigen-negative CHB genotype D patients (20 men and 8 women; median age, 54 years [range, 47-58 years]) who underwent NA (n = 20) or PEG-IFN-α (n = 8) treatment. Serum HBcrAg levels were determined by chemiluminescent enzyme immunoassay. Longitudinal analysis was carried out at 6, 12, 24, and 36 months after NA treatment initiation and at 6, 12, and 18 months and at follow-up month 6 after PEG-IFN-α treatment. RESULTS Basal HBcrAg levels were 4.7 ± 1.8 Log U/mL and 3.3 ± 1.6 Log U/mL in NA- and PEG-IFN-α-treated patients, respectively. Hepatitis B core-related antigen showed a moderate correlation with HBV DNA (r = 0.498, P < 0.0001) and no correlation with HBsAg (r = 0.192, P = 0.0669). In serial serum samples, a significant HBcrAg reduction was observed only in patients receiving NA (P = 0.019). In these patients, we observed a group (n = 12) with an early HBcrAg decline to undetectable levels between months 6-12, whereas the other group (n = 8) still had detectable HBcrAg at month 36 (4.4 ± 0.6 Log U/mL), independently from HBV DNA and HBsAg kinetics. CONCLUSIONS Serum HBcrAg correlates with HBV DNA levels, most likely through expression of viral replication activity. We observed two different HBcrAg kinetics in NA-treated patients, suggesting different relapse risk related to NA cessation. Further studies on larger patient cohorts will elucidate the role of HBcrAg in the safe discontinuation of NA in CHB genotype D patients.

Abstract
BACKGROUND & AIMS Hepatitis B virus (HBV) covalently closed circular DNA (cccDNA) is a key to viral persistence in chronic hepatitis B infection. Serum hepatitis B core-related antigen (HBcrAg) is a novel marker for HBV disease. We aimed to determine whether HBcrAg could be a surrogate marker for intrahepatic cccDNA. METHODS Three hundred and five liver biopsies and the corresponding sera collected from 138 nucleos(t)ide analogues-treated patients were analysed. 124 patients had paired liver biopsies at baseline and 1-year post-treatment, and 43 patients had a third biopsy after 6-12 years of treatment. Serum HBcrAg, HBV DNA and hepatitis B surface antigen (HBsAg), and intrahepatic HBV DNA and cccDNA were measured. RESULTS HBcrAg strongly correlated with cccDNA (r=.70), intrahepatic total HBV DNA (r=.67) and serum HBV DNA (r=.69; all P<.0001). In the 130 samples with undetectable serum HBV DNA, HBcrAg was detectable in 101 (78%) samples, and HBcrAg levels still correlated positively with cccDNA (r=.42, P<.0001). At ≥6 years of therapy, the median logarithmic reduction in HBcrAg was 2.7 log kU/mL, which was comparable to the magnitude of reduction in cccDNA. Twenty-one patients had undetectable cccDNA after ≥6 years of treatment, in whom 15 (71%) had detectable HBcrAg (range: 1.2-537 kU/mL). CONCLUSIONS Serum HBcrAg is a reliable surrogate marker for intrahepatic cccDNA. HBcrAg could be a very sensitive marker to reflect the cccDNA content and persistence of disease even with the cccDNA levels below the detection limit of assays.

Abstract
Early prediction of spontaneous hepatitis B virus e antigen (HBeAg) seroconversion is pivotal in the prevention of unnecessary drug prescription, corresponding financial burden, and adverse reactions. One hundred and thirteen chronic hepatitis B patients with HBeAg-positive in the immune active phase were followed up for about 1.5 years. Patients were classified into two groups: spontaneous HBeAg seroconversion group (group A, n = 18) and non-spontaneous HBeAg seroconversion group. Among the non-spontaneous HBeAg seroconversion group, 35 patients were selected as controls (group B, n = 35). At week 12, there was a significant difference in hepatitis B core-related antigen (HBcrAg) levels between the two groups (group A 4.32 ± 1.05 log10 kU/ml, and group B 5.16 ± 0.53 log10 kU/ml, P = 0.004), and this significance magnified at week 28. Only two variables, HBcrAg level and the reduction in the HBcrAg levels (ΔHBcrAg) at week 28 were enrolled, with the odds ratio of 4.19 and 0.21, respectively. The optimal cutoffs of HBcrAg levels and the ΔHBcrAg at week 28 were 4.90 and 2.00 log10 kU/ml, respectively. The positive predictive value and negative predictive value of HBcrAg levels at week 28 were 73.9% and 96.7%, respectively. The positive predictive value and negative predictive value of the ΔHBcrAg at week 28 were 76.2% and 93.8%, respectively. The measurement of HBcrAg is useful for monitoring the natural course of chronic hepatitis B virus infection. The dynamics of HBcrAg levels could accurately predict the spontaneous HBeAg seroconversion. J. Med. Virol. 89:463-468, 2017. © 2016 Wiley Periodicals, Inc.

Abstract
BACKGROUND & AIMS The role of quantitative serum hepatitis B core-related antigen (HBcrAg) in patients with chronic hepatitis B (CHB) receiving pegylated interferon (PEG-IFN) is unclear. This study was aimed at comparing its usefulness with quantitative HBsAg in patients with HBeAg-positive CHB receiving PEG-IFN therapy. METHODS A total 46 patients treated with PEG-IFN for 48 weeks were retrospectively analysed. Intrahepatic covalently closed circular DNA (cccDNA) from paired liver biopsies and serial serum HBsAg and HBcrAg during therapy were assessed. RESULTS Virological response (VR), defined as HBeAg clearance and HBV DNA <2000 IU/ml at 24 weeks post treatment, was achieved in 15 (32.6%) patients. Responders had significantly higher cccDNA decline from baseline compared with non-responders. Baseline HBsAg and HBcrAg were correlated with cccDNA (r = 0.424, P = 0.020 and r = 0.564, P = 0.001, respectively), and changes in the corresponding markers during therapy were correlated with cccDNA reduction (r = 0.579, P = 0.001 and r = 0.503, P = 0.005, respectively). Responders showed more rapid decline of both markers during therapy compared with non-responders. In multivariate analysis, serum HBcrAg at week 12 was identified as a predictor of VR. The optimal cut-off value for HBcrAg (log10 8.0 U/ml) provided negative predictive value (NPV) of achieving VR at weeks 12 and 24 of 94.4 and 100%, respectively, while using HBsAg > 20 000 IU/ml provided NPV of 80 and 100% respectively. CONCLUSIONS The convenient quantitative HBcrAg represented a reliable marker of intrahepatic cccDNA. Monitoring HBcrAg levels during PEG-IFN therapy may help identify patients with a very low probability of response comparable to, if not better than, quantitative HBsAg.

Abstract
Hepatitis B core-related antigen (HBcrAg), a new serum marker, may be useful in monitoring chronic hepatitis B infection. HBcrAg was measured in 175 hepatitis B e antigen-positive patients treated with entecavir (ETV) with or without peginterferon (PEG-IFN) add-on therapy. Decline in HBcrAg was stronger in patients with vs. without combined response (ETV: -3.22 vs. -1.71 log U/mL, p <0.001; PEG-IFN add-on: -3.16 vs. -1.83 IU/mL, p <0.001) and in patients with vs. without hepatitis B surface antigen (HBsAg) response (ETV: -2.60 vs. -1.74 log U/mL, p <0.001; PEG-IFN add-on: -2.38 vs. -2.15 log U/mL, p = 0.31). HBcrAg was associated with combined response (adjusted odds ratio 0.3, 95% confidence interval 0.2-0.5, p <0.001), but was not superior to quantitative HBsAg (qHBsAg).

Abstract
AIM The factors associated with the outcome of sequential therapy with interferon-α (IFN-α) in order to halt nucleoside/nucleotide analog (NUC) maintenance treatment for chronic hepatitis B were analyzed. METHODS A total of 50 patients with chronic hepatitis B who underwent IFN-α sequential therapy for cessation of NUC were enrolled retrospectively. The subjects received NUC plus IFN-α for 4 weeks followed by IFN-α alone for 20 weeks. Natural IFN-α of 6-MU doses was administrated three times a week. A successful response to NUC/IFN-α sequential therapy was defined as serum hepatitis B virus (HBV) DNA below 4.0 log copies/mL, serum alanine aminotransferase (ALT) below 30 IU/L, and hepatitis B e-antigen negativity at 24 months after completing the treatment. RESULTS Multivariate analysis revealed that hepatitis B surface antigen (HBsAg) of 3.0 log U/mL or more (P < 0.002) and hepatitis B core-related antigen (hepatitis B core-related antigen [HBcrAg]) of 4.5 log U/mL or more (P < 0.003) at the start of IFN-α administration were significant factors associated with a 24-month non-response. Maximal levels of ALT and HBV DNA during the follow-up period after completing IFN-α therapy were significantly related (P < 0.001), and receiver operating characteristic analysis showed that both maximal ALT (P < 0.001) and HBV DNA (P < 0.001) were significantly related to the final 24-month response. CONCLUSION The combinational use of HBsAg and HBcrAg levels may be useful to predict the 24-month outcome of NUC/IFN-α sequential therapy. Maximal levels of ALT and HBV DNA during post-treatment follow-up may also help monitor responses to IFN-α sequential therapy.

Hepatitis B core-related antigen (HBcrAg) levels in the natural history of hepatitis B virus infection in a large European cohort predominantly infected with genotypes A and D. Clin Microbiol Infect 2015; 21:606.e1-10.

Abstract
Hepatitis B core-related antigen (HBcrAg) has been suggested as an additional marker of hepatitis B virus (HBV) infection. HBcrAg combines the antigenic reactivity resulting from denatured hepatitis B e antigen (HBeAg), HBV core antigen and an artificial core-related protein (p22cr). In Asian patients, high levels of HBcrAg have been suggested to be an independent risk factor for hepatocellular carcinoma, while low levels could guide safe cessation of treatment with nucleos(t)ide analogues. We here studied HBcrAg levels in different phases of HBV infection in a large European cohort predominantly infected with genotypes A and D: HBeAg-positive immune tolerance (n = 30), HBeAg-positive immune clearance (IC) (n = 60), HBeAg-negative hepatitis (ENH) (n = 50), HBeAg-negative inactive/quiescent carrier phase (c) (n = 109) and acute hepatitis B (n = 8). Median HBcrAg levels were high in the immune tolerance and immune clearance phases (8.41 and 8.11 log U/mL, respectively), lower in ENH subjects (4.82 log U/mL) but only 2.00 log U/mL in ENQ subjects. Correlation between HBcrAg and HBV DNA varied among the different phases of HBV infection, while HBcrAg moderately correlated with hepatitis B surface antigen in all phases. ENQ patients had HBcrAg levels <3 log U/mL in 79%, in contrast to only 12% in the ENH group. HBcrAg levels vary significantly during the different phases of HBV infection. HBcrAg may serve as valuable marker for virus replication and reflect the transcriptional activity of intrahepatic cccDNA. In HBeAg-negative patients, HBcrAg may help to distinguish between inactive carriers (ENQ) and those with active disease (ENH).

Abstract
AIM We sought to clarify the associations between serum cytokines and chemokines, hepatitis B surface antigen (HBsAg), hepatitis B core-related antigen (HBcrAg), and hepatitis B virus (HBV) DNA and response to entecavir therapy in chronic hepatitis B. METHODS We analyzed six cytokines (interleukin [IL]-2, IL-6, IL-10, IL-12p70, IL-21 and IL-22) and five chemokines (CCL2, CCL3, CXCL9, CXCL10 and CXCL11) before and at 6, 12 and 24 months during entecavir therapy in 48 chronic hepatitis B patients. Quantitative measurement of HBsAg, HBcrAg and HBV DNA was performed. A virological response (VR) was defined as serum HBV DNA of less than 2.1 log copies/mL by treatment month 24. RESULTS Thirty-nine patients (81%) achieved a VR. Serum IL-6 (P = 0.031), CXCL-9 (P = 0.002), and CXCL-10 (P = 0.001) were high in chronic HBV and correlated positively with transaminases and bilirubin. Before treatment, elevated IL-22 (P = 0.031) and lower HBsAg (P = 0.001) and HBcrAg (P < 0.001), but not HBV DNA, were associated with a favorable treatment outcome. In multivariate analysis, high IL-22 (hazard ratio = 13.67, P = 0.046) and low HBcrAg (hazard ratio = 10.88, P = 0.048) were independently associated with a VR. The levels of IL-22 (P < 0.001), HBsAg (P < 0.001), and HBcrAg (P < 0.001) all decreased from baseline to 24 months of treatment in virological responders. CONCLUSION Serum IL-22 and HBcrAg are predictive markers of a VR to entecavir therapy in patients with chronic hepatitis B.

Abstract
AIM We analyzed the characteristics of alanine aminotransferase (ALT) abnormality after achieving hepatitis B e-antigen (HBeAg) seroconversion (SC) and other factors associated with the occurrence of HBeAg negative hepatitis. METHODS We followed 36 patients with chronic hepatitis B from 3 years prior to at least 3 years after SC (mean, 11.6 years) and examined ALT, hepatitis B virus (HBV) DNA, HB surface antigen, HB core-related antigen (HBcrAg) levels and mutations related to HBeAg SC. RESULTS ALT normalization (<31 IU/L for at least 1 year) was primarily observed until 2 years following SC, after which it became more infrequent. We next divided patients into abnormal (≥31 IU/L, n = 20) and normal (<31 IU/L, n = 16) groups based on integrated ALT level after the time point of 2 years from SC, and considered the former group as having HBeAg negative hepatitis in the present study. Although changes in median levels of ALT and HBcrAg differed significantly between the groups, multivariate analysis showed ALT normalization within 2 years after SC to be the only significant determining factor for this disease (P = 0.001). We then assessed the 19 patients whose ALT was normal at 2 years following SC, four of whom developed HBeAg negative hepatitis. Increased levels of HBV DNA (P = 0.037) and HBcrAg (P = 0.033) were significant factors of potential relevance. CONCLUSION ALT abnormality after 2 years of SC may be evaluated as HBeAg-negative hepatitis. ALT, HBV DNA and HBcrAg levels may be useful in predicting the outcome of patients who achieve HBeAg SC.
