Abstract
The management of hepatitis B virus (HBV) infection now involves regular and appropriate monitoring of viral activity, disease progression, and treatment response. Traditional HBV infection biomarkers are limited in their ability to predict clinical outcomes or therapeutic effectiveness. Quantitation of HBV core antibodies (qAnti-HBc) is a novel non-invasive biomarker that may help with a variety of diagnostic issues. It was shown to correlate strongly with infection stages, hepatic inflammation and fibrosis, chronic infection exacerbations, and the presence of occult infection. Furthermore, qAnti-HBc levels were shown to be predictive of spontaneous or treatment-induced HBeAg and HBsAg seroclearance, relapse after medication termination, re-infection following liver transplantation, and viral reactivation in the presence of immunosuppression. qAnti-HBc, on the other hand, cannot be relied on as a single diagnostic test to address all problems, and its diagnostic and prognostic potential may be greatly increased when paired with qHBsAg. Commercial qAnti-HBc diagnostic kits are currently not widely available. Because many methodologies are only semi-quantitative, comparing data from various studies and defining universal cut-off values remains difficult. This review focuses on the clinical utility of qAnti-HBc and qHBsAg in chronic hepatitis B management.

J Clin Med 2023; 13:23. [PMID: 38202030 PMCID: PMC10779810 DOI: 10.3390/jcm13010023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 11/06/2023] [Accepted: 12/08/2023] [Indexed: 01/12/2024] Open
Abstract
Background: Patients with lymphoma and chronic hepatitis B virus infection need to be treated with both chemotherapy and nucleotide analogue (NA) therapy. However, dynamic changes in HBV DNA loads with increasing chemotherapy cycles are lacking. It is unknown whether HBV replication markers, namely, the quantitative hepatitis B core antibody (qAnti-HBc), HBV RNA, and the hepatitis B virus core-related antigen (HBcrAg), are also markers for predicting HBV reactivation (HBVr). Methods: From 29 June 2010 to 6 December 2021, the data of patients with single-site diffuse large B-cell lymphoma and HBV infection (HBsAg+ and HBsAg-/anti-HBc+) were collected from a hospital medical record system, retrospectively. Serum HBV DNA loads (using real-time fluorescent quantitative PCR tests), qAnti-HBc levels (using a newly developed chemiluminescent particle immunoassay), HBV RNA levels (using the simultaneous amplification testing method based on real-time fluorescence detection), and HBcrAg levels (using a Lumipulse G HBcrAg assay) were tested, and factors related to HBVr were analyzed. Results: Under NAs, the HBV DNA loads of 69 HBsAg+ lymphoma patients declined from 3.15 (2.13-4.73) lg IU/mL to 1.00 (1.00-1.75) lg IU/mL, and further declined to 1.00 (1.00-1.04) lg IU/mL at the end of a 24-month follow-up. The qAnti-HBc levels decreased gradually during chemotherapy in HBsAg+ lymphoma patients (F = 7.090, p = 0.009). The HBV RNA and HBcrAg levels remained stable. A multivariate analysis revealed that higher qAnti-HBc levels (1.97 ± 1.20 vs. 1.12 ± 0.84 lg IU/mL, OR = 6.369, [95% CI: 1.523-26.641], p = 0.011) and higher HBV RNA levels (1.00 ± 1.13 vs. 0.37 ± 0.80 lg copies/mL, OR = 3.299, [95% CI: 1.229-8.854], p = 0.018) were related to HBVr in HBsAg-/anti-HBc+ lymphoma patients. Conclusions: HBV DNA loads declined under NAs during chemotherapy in lymphoma patients. In HBsAg-/anti-HBc+ lymphoma patients, a higher level of baseline serum qAnti-HBc and HBV RNA levels can predict the likelihood of HBVr during chemotherapy.

BMC Gastroenterol 2023; 23:348. [PMID: 37803352 PMCID: PMC10557289 DOI: 10.1186/s12876-023-02983-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Accepted: 09/28/2023] [Indexed: 10/08/2023] Open
Abstract
BACKGROUND AND AIM In chronic hepatitis B infection (CHB), seroclearance of hepatitis B surface antigen (HBsAg) is associated with favourable clinical outcomes compared to those with persistent HBsAg seropositivity, and thus considered as a desired treatment endpoint. This current study explores the possibility of serum antibody to hepatitis B core antigen (anti-HBc) as a potential predictive factor of HBsAg seroclearance. METHODS This is a retrospective study that analyzed the plasma samples of CHB patients using the LUMIPULSE® G1200 analyzer. The longitudinal anti-HBc level between patients who subsequently achieved HBsAg seroclearance (S-losers) and those with persistent HBsAg-positivity (controls) were compared at multiple time points before the event. RESULTS A total of 240 subjects (120 S-losers and 120 controls; age- and gender-matched) were included (mean age 56.42 ± 10.81, 65% male). Compared to controls, S-losers had significantly lower plasma anti-HBc levels prior to HBsAg seroclearance, with a significant trend of declining plasma anti-HBc 8-5 years prior to HBsAg seroclearance (p < 0.01), while such trend was not observed in controls. ROC curve analysis revealed that plasma anti-HBc at multiple time points before HBsAg seroclearance return AUC greater than 0.7. Plasma anti-HBc level at the cut-off value of 82.50 COI was 68.3% sensitive and 90% specific for HBsAg seroclearance within 1 year. Combining with quantitative HBsAg < 100 IU/mL, anti-HBc < 82.5 COI identified 88.2% patients who would develop HBsAg seroclearance within 1 year. CONCLUSION Plasma anti-HBc level began to decline 10 years prior to HBsAg seroclearance and can serve as a potential predictor for subsequent HBsAg seroclearance.

Atypical Hepatitis B Virus Serology Profile-Hepatitis B Surface Antigen-Positive/Hepatitis B Core Antibody-Negative-In Hepatitis B Virus/HIV Coinfected Individuals in Botswana. Viruses 2023; 15:1544. [PMID: 37515230 PMCID: PMC10383918 DOI: 10.3390/v15071544] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 07/10/2023] [Accepted: 07/11/2023] [Indexed: 07/30/2023] Open
Abstract
(1) Background: Hepatitis B core antibodies (anti-HBc) are a marker of hepatitis B virus (HBV) exposure; hence, a normal HBV serology profile is characterized by HBV surface antigen (HBsAg) and anti-HBc positivity. However, atypical HBV serologies occur, and we aimed to determine the prevalence of an atypical profile (HBsAg+/anti-HBc-) in a cohort of people with HIV-1 (PWH) in Botswana. (2) Methods: Plasma samples from an HIV-1 cohort in Botswana (2013-2018) were used. The samples were screened for HBsAg and anti-HBc. Next-generation sequencing was performed using the GridION platform. The Wilcoxon rank-sum test and Chi-squared tests were used for the comparison of continuous and categorical variables, respectively. (3) Results: HBsAg+/anti-HBc- prevalence was 13.7% (95% CI 10.1-18.4) (36/263). HBsAg+/anti-HBc- participants were significantly younger (p < 0.001), female (p = 0.02) and ART-naïve (p = 0.04) and had a detectable HIV viral load (p = 0.02). There was no statistically significant difference in the number of mutations observed in participants with HBsAg+/anti-HBc- vs. those with HBsAg+/anti-HBc+ serology. (4) Conclusions: We report a high HBsAg+/anti-HBc- atypical serology profile prevalence among PWH in Botswana. We caution against HBV-testing algorithms that consider only anti-HBc+ samples for HBsAg testing, as they are likely to underestimate HBV prevalence. Studies to elucidate the mechanisms and implications of this profile are warranted.

Factors associated with persistent positive in HBV DNA level in patients with chronic Hepatitis B receiving entecavir treatment. Front Cell Infect Microbiol 2023; 13:1151899.

Abstract
Introduction The clinical significance of persistent positive in Hepatitis B Virus (HBV) DNA level in patients receiving antiviral therapy is not well known. We investigated factors associated with persistent viremia (PV) in patients with chronic hepatitis B (CHB) given 78-week entecavir. Methods A total of 394 treatment-naïve CHB patients who had undergone liver biopsy at baseline and week 78 of treatment were analyzed in this prospective multicentre study. We identified patients with PV (above the lower limit of quantification, 20 IU/ml) after 78 weeks of entecavir therapy. Stepwise, forward, multivariate regression analyses of specified baseline parameters were apllied to identify factors associated with PV. Futhermore, we assessed the incidence of hepatocellular carcinoma (HCC) in all patients using models of the risk of HCC development. Results Of the 394 patients, 90 (22.8%) still with PV after 78-week antiviral treatment. Factors associated significantly with PV (vs complete virological response, CVR) were HBV DNA level ≥8 log10 IU/mL (OR, 3.727; 95% CI, 1.851-7.505; P < 0.001), Anti-HBc level < 3 log10 IU/mL (OR, 2.384; 95% CI, 1.223-4.645; P=0.011), and HBeAg seropositivity (OR, 2.871; 95% CI, 1.563-5.272; P < 0.001). Patients with PV were less likely to have fibrosis progression and HCC development than those with the CVR. Of the 11 HBeAg-positive patients with HBV DNA level ≥8 log10 IU/mL and Anti-HBc level < 3 log10 IU/mL at baseline, 9 (81.8%) had persistent positivity in HBV DNA level and 0 had fibrosis progression at week 78 of treatment. Discussion In conclusion, HBV DNA level ≥8 log10 IU/mL, Anti-HBc level < 3 log10 IU/mL and HBeAg seropositivity at baseline contribute to PV in patients with CHB receiving 78-week antiviral treatment. In addition, the rate of fibrosis progression and the risk of HCC development in patients with PV were kept low. The complete protocol for the clinical trial has been registered at clinicaltrials.gov (NCT01962155 and NCT03568578).

Abstract
The hepatitis B virus core protein (HBcAg) is a highly immunogenic particulate antigen. Nearly all patients with persistent or resolved hepatitis B virus (HBV) infection show seropositivity for hepatitis B core antibody (anti-HBc), which appears in the early stage of infection and is mostly present for life. Traditionally, the anti-HBc is regarded as an evidential serological marker of HBV infections. In the last ten years, several studies revealed the predictive value of quantitative anti-HBc (qAnti-HBc) level in the treatment response and clinical outcome of chronic HBV infections, implying new insights into this classic marker. Overall, qAnti-HBc should be regarded as an indicator of the host's immune response specific to HBV, which correlates with HBV-related hepatitis activity and liver pathology. This review summarized the latest understanding of the clinical values of qAnti-HBc for differentiating the CHB phase, predicting treatment response, and providing disease prognosis. Moreover, we also discussed the possible mechanism of qAnti-HBc regulation during different courses of HBV infection.

Abstract
Despite the availability of an effective hepatitis B virus (HBV) vaccine and universal immunization schedules, HBV has remained a health problem in various stages such as occult hepatitis B infection (OBI), chronic hepatitis B (CHB), and hepatocellular carcinoma (HCC), which is considered one of the possible phases during chronic HBV infection. OBI is defined as the persistence of HBV genomes in hepatocytes of patients with a negative HBV surface antigen (HBsAg) test and detectable or undetectable HBV DNA in the blood. OBI is occasionally associated with infection caused by mutant viruses that produce a modified HBsAg that is undetected by diagnostic procedures or with replication-defective variations. Many aspects of HBV (OBI more than any other stage) including prevalence, pathobiology, and clinical implications has remained controversial. According to a growing body of research, non-coding RNAs (lncRNAs) and microRNAs (miRNAs) have been linked to the development and progression of a number of illnesses, including viral infectious disorders. Despite a shortage of knowledge regarding the expression and biological activities of lncRNAs and miRNAs in HBV infection, Hepatitis B remains a major global public health concern. This review summarizes the role of lncRNAs in the diagnosis and treatment of different stages of hepatitis B infection.

HBsAg (-)/HBsAb (-)/HBeAg (-)/HBeAb (+)/HBcAb (+) predicts a high risk of hepatitis B reactivation in patients with B-cell lymphoma receiving rituximab based immunochemotherapy. J Med Virol 2023; 95:e28549. [PMID: 36734081 DOI: 10.1002/jmv.28549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2022] [Revised: 12/30/2022] [Accepted: 01/24/2023] [Indexed: 02/04/2023]
Abstract
Patterns of hepatitis B virus reactivation (HBV-R) in HBsAg (-)/HBcAb (+) patients with B-cell non-Hodgkin lymphoma (NHL) receiving rituximab based immunochemotherapy have not been well described. The retrospective study included 222 HBsAg (-)/HBcAb (+) NHL patients as training cohort and 127 cases as validation cohort. The incidence of HBV-R in HBsAg (-)/HBcAb (+) B-cell NHL patients was 6.3% (14/222), of which that in HBsAg (-)/HBsAb (-)/HBeAg (-)/HBeAb (+)/HBcAb (+) population was 23.7% (9/38). Multivariate analysis showed that HBsAg (-)/HBsAb (-)/HBeAg (-)/HBeAb (+)/HBcAb (+) correlated with a high risk of HBV-R in B-cell lymphoma patients (training phase hazard ratio [HR], 10.123; 95% confidence interval [CI], 3.389-30.239; p < 0.001; validation phase HR, 18.619; 95% CI, 1.684-205.906; p = 0.017; combined HR, 12.264; 95% CI, 4.529-33.207; p < 0.001). In the training cohort, the mortality rate of HBsAg (-)/HBcAb (+) B-cell NHL caused by HBV-R was 14.3% (2/14) while that for HBV reactivated HBsAg (-)/HBsAb (-)/HBeAg (-)/HBeAb (+)/HBcAb (+) population was up to 44.4% (4/9). As a high incidence of HBV-R and high mortality after HBV-R was found in HBsAg (-)/HBsAb (-)/HBcAb (+)/HBeAg (-)/HBeAb (+) patients with B-cell NHL receiving rituximab based immunochemotherapy, prophylactic antiviral therapy is recommended for these patients.

Effective Analysis of Antiviral Treatment in Patients with HBeAg-Seropositive Chronic Hepatitis B with ALT < 2 Upper Limits of Normal: A Multi-center Retrospective Cohort Study. Infect Dis Ther 2023; 12:637-647. [PMID: 36633817 PMCID: PMC9925662 DOI: 10.1007/s40121-022-00757-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2022] [Accepted: 12/22/2022] [Indexed: 01/13/2023] Open
Abstract
INTRODUCTION Although the indications for antiviral therapy for patients with chronic hepatitis B have been gradually expanded in different guidelines, antiviral treatment efficacy remains unclear among HBeAg-seropositive patients with alanine aminotransferase (ALT) < 2 upper limits of normal (ULN). This study aimed to evaluate the efficacy of antiviral therapy for these patients. METHODS In total, 102 treatment-naive patients who were HBeAg seropositive with ALT < 2 ULN and had received nucleotide analogs were included, and their clinical data were retrospectively analyzed. RESULTS After 96-week treatment, 84.3% (n = 86), 26.5% (n = 27) and 20.6% (n = 21) patients achieved virological response, HBeAg seroclearance and HBeAg seroconversion, respectively. Logistic regression analysis revealed that baseline AST (odds ratio [OR] = 1.069, 95% confidence interval [CI] 1.014-1.127, p = 0.014), serum HBV DNA (OR = 0.540, 95% CI 0.309-0.946, p = 0.031) and quantitative HBsAg levels (OR = 0.147, 95% CI 0.036-0.597, p = 0.007) were independent factors for virological response. At baseline, HBsAg < 4.63 log10 IU/ml was identified as a strong predictor for the 96-week virological response, with a concordance rate of 0.902. Moreover, the levels of liver stiffness values (8.30 ± 3.86 vs. 6.17 ± 1.91, p < 0.001) at week 96 had significantly declined compared to baseline. CONCLUSION Nucleotide analog treatment effectively suppressed HBV DNA in patients with HBeAg-seropositive chronic hepatitis B with ALT < 2 × ULN and greatly improved liver fibrosis. The study also found that HBsAg < 4.63 log10 IU/ml was a strong predictor of the virological response.

Clinical Utility of Quantitative HBV Core Antibodies for Solving Diagnostic Dilemmas. Viruses 2023; 15:v15020373. [PMID: 36851587 PMCID: PMC9965363 DOI: 10.3390/v15020373] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2022] [Revised: 01/20/2023] [Accepted: 01/26/2023] [Indexed: 01/31/2023] Open
Abstract
The present-day management of hepatitis B virus (HBV) infection relies on constant and appropriate monitoring of viral activity, disease progression and treatment response. Traditional HBV infection biomarkers have many limitations in predicting clinical outcomes or therapy success. Quantitation of HBV core antibodies (qAnti-HBc) is a new non-invasive biomarker that can be used in solving multiple diagnostic problems. It was shown to correlate well with infection phases, level of hepatic inflammation and fibrosis, exacerbations during chronic infection and presence of occult infection. Further, the level of qAnti-HBc was recognised as predictive of spontaneous or therapy-induced HBeAg and HBsAg seroclearance, relapse after therapy discontinuation, re-infection after liver transplantation and viral reactivation upon immunosuppression. However, qAnti-HBc cannot be relied upon as a single diagnostic test to solve all dilemmas, and its diagnostic and prognostic power can be much improved when combined with other diagnostic biomarkers (HBV DNA, HBeAg, qHBsAg and anti-HBs antibodies). The availability of commercial qAnti-HBc diagnostic kits still needs to be improved. The comparison of results from different studies and definitions of universal cut-off values continue to be hindered because many methods are only semi-quantitative. The clinical utility of qAnti-HBc and the methods used for its measurement are the focus of this review.

Low anti-HBc levels are associated with lower risk of virological relapse after nucleos(t)ide analogue cessation in HBe antigen-negative patients. Liver Int 2022; 42:2674-2682. [PMID: 36152268 DOI: 10.1111/liv.15433] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Revised: 07/25/2022] [Accepted: 09/06/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND AND AIMS Low anti-HBc serum levels at the time of therapy cessation were linked to a higher relapse risk in predominantly HBeAg-positive cohorts. We investigated the association of anti-HBc levels with relapse in HBeAg-negative patients. METHODS Serum levels of anti-HBc, HBsAg and HBcrAg were determined in 136 HBeAg-negative patients, participating in a vaccination trial (ABX-203, NCT02249988), before treatment cessation or vaccination. Importantly, vaccination showed no impact on relapse. The correlation between the biomarkers and their predictive value for relapse (HBV DNA >2000 IU/ml ± ALT >2xULN) was investigated. RESULTS After therapy cessation 50% (N = 68) of patients relapsed. Median anti-HBc prior to treatment stop was significantly higher among relapsers compared to off-treatment responders (520 IU/ml vs. 330 IU/mL, p = .0098). The optimal anti-HBc cut-off to predict relapse was 325 IU/ml according to the Youden-Index. About 35% of patients with anti-HBc level < 325 IU/ml versus 60% of those with values ≥325 IU/mL relapsed (p = .0103; sensitivity 50%, specificity 75%). Combining the optimal cut-offs of HBsAg (>3008 IU/mL) or HBcrAg (≥1790 U/ml) with anti-HBc increased the proportion of patients with relapse to 80% (p < .0001) and 74% (p = .0006), respectively. CONCLUSION In contrast to predominantly HBeAg-positive cohorts, in our cohort of HBeAg-negative patients lower anti-HBc levels are associated with a significantly lower relapse risk after nucleos(t)ide analogue cessation. The vast majority of included patients were either genotype B or C and the applicability to other genotypes has to be further evaluated. However, anti-HBc level as an indicator of the host response might be prospectively further explored for prediction models.

Abstract
BACKGROUND Chronic hepatitis B remains a global health problem with an estimated 296 million people affected worldwide. Individuals are at risk of serious complications such as cirrhosis and hepatocellular carcinoma and accurately predicting these clinical endpoints has proven difficult. However, several viral biomarkers have recently been developed, including quantitative HBV surface antigen (qHBsAg), hepatitis B RNA (HBV RNA) and core-related antigen (HBcrAg), and shown promise in a range of clinical settings. AIMS To critically appraise these novel biomarkers, exploring their potential uses, availability of assays and areas for future development. METHODS We performed a literature search of PubMed, identifying articles published in the field of hepatitis B biomarkers between 2010 and 2022. RESULTS Novel biomarkers such as HBcrAg, HBV RNA and qHBsAg may be useful in predicting treatment outcomes, stratifying the risk of future complications and estimating off-treatment viral reactivation. Furthermore, HBV RNA and HBcrAg titres may accurately reflect cccDNA transcriptional activity, and this is particularly informative in the context of nucleoside analogue therapy. On a cautionary note, most studies have been performed in Caucasian or Asian populations, and methods for detecting HBV RNA lack standardisation. CONCLUSION Novel viral biomarkers have the potential to provide additional insights into the natural history of infection and allow a more bespoke, cost-effective framework of care. However, access remains limited, and further efforts are needed to validate their use in ethnically diverse populations, confirm predictive cut-off values, and establish their role in the era of novel antiviral therapies.

Abstract
Background and aimsPrecise predictors are lacking for hepatitis B surface antigen (HBsAg) clearance under the combination therapy of nucleos(t)ide analogs (NA) and pegylated interferon-alpha (PEG-IFN-α) in patients with chronic hepatitis B (CHB). This study aimed to determine the quantitative anti-hepatitis B core antibody (qAnti-HBc) and quantitative hepatitis B core-related antigen (qHBcrAg) as predictors for HBsAg clearance in NA-suppressed patients with CHB receiving PEG-IFN-α add-on therapy.MethodsSeventy-four CHB patients who achieved HBV DNA suppression (HBV DNA < 20 IU/ml) and quantitative HBsAg (qHBsAg) < 1,500 IU/ml after ≥1 year of NA treatment were enrolled. Fifteen patients continued on NA monotherapy, while 59 patients received PEG-IFN-α add-on therapy. Serum qAnti-HBc and qHBcrAg levels were detected every 12 or 24 weeks for add-on and NA-alone groups, respectively.ResultsSerum qAnti-HBc but not qHBcrAg levels at baseline were negatively correlated with the duration of prior NA therapy. After 48-week treatment, both qAnti-HBc and qHBcrAg levels declined further, and 17/59 (28.81%) and 0/15 (0%) achieved HBsAg clearance in add-on and NA groups, respectively. In the add-on group, the rate of HBsAg clearance was significantly higher in patients with baseline qAnti-HBc < 0.1 IU/ml (52.63%). Logistic regression analysis identified baseline qAnti-HBc but not qHBcrAg, which was an independent predictor for HBsAg loss. Receiver operating characteristic curve analysis showed that the combination of qAnti-HBc and qHBsAg had a better predictive value for HBsAg clearance.ConclusionsA combination of qHBsAg and baseline qAnti-HBc levels may be a better prediction strategy for HBsAg clearance in NA-suppressed CHB patients receiving PEG-IFN-α add-on therapy.

Abstract
Insights into the immunopathogenesis of chronic HBV infections are fundamental in the quest for novel treatment approaches aimed at a functional cure. While much is known about the ineffective HBV-specific T-cell responses that characterise persistent HBV replication, B cells have been left largely understudied. However, an important role for humoral immunity during the natural history of HBV infections, as well as after functional cure, has been inadvertently revealed by the occurrence of HBV flares following B cell-depleting treatments. Herein, we review our current understanding of the role of the humoral immune response in chronic HBV, both at the level of HBV-specific antibody production and at the phenotypic and broader functional level of B cells. The recent development of fluorescently labelled HBV proteins has given us unprecedented insights into the phenotype and function of HBsAg- and HBcAg-specific B cells. This should fuel novel research into the mechanisms behind dysfunctional HBsAg-specific and fluctuating, possibly pathogenic, HBcAg-specific B-cell responses in chronic HBV. Finally, novel immunomodulatory treatments that partly target B cells are currently in clinical development, but a detailed assessment of their impact on HBV-specific B-cell responses is lacking. We plead for a rehabilitation of B-cell studies related to both the natural history of HBV and treatment development programmes.

Abstract
Hepatitis B virus infection results in the appearance of anti-HBc antibodies that normally persist lifelong. We analyzed the course of anti-HBc antibodies overtime, focusing on patients with a permanent loss or fluctuating anti-HBc antibodies. From 120,531 patients tested for anti-HBc antibodies (Architect, Abbott) from January 2006 to December 2020, ≥4 serial values were available in 8098 and permanent or intermittent anti-HBc loss was observed in 139 patients. It was relatively frequent in baseline anti-HBc positive, immunocompromised patients with available serial measurements of anti-HBc overtime (13% of hematologic/oncologic patients, 10% of solid organ transplant recipients, and 6% of HIV patients compared to 3% in patients with other diseases). In the same period, 12,607 samples were tested for HBsAg, anti-HBc antibodies, and HBV DNA—in nine cases we detected HBV DNA with undetectable anti-HBc and HBsAg. In four out of nine cases contamination of the PCR during processing was the likeliest cause, in another four, no further data were available, while in one the HBV DNA was later followed by a temporary anti-HBc seroconversion. In conclusion, permanent or intermittent anti-HBc loss is more common in immunocompromised hosts than in patients with other underlying diseases. Furthermore, anti-HBc and HBsAg assays can be safely used to exclude an active HBV infection, even in immunocompromised hosts.

Abstract
BACKGROUND/AIMS We investigated the efficiency of the indirect ratio of anti-HBc IgG at predicting HBsAg seroclearance in patients with nucleos(t)ide analogue (NA)-induced HBeAg seroclearance. METHODS We performed a retrospective study that included 366 chronic hepatitis B patients (March 2007 to December 2016) at a single tertiary hospital. These patients were HBsAg seropositive, and experienced NA-induced HBeAg seroclearance. The indirect ratio of light absorbance of anti-HBc IgG levels were measured with chemiluminescent microparticle immunoassay using the Architect Anti-HBc assay (Abbott Laboratories, IL, USA) as a qualitative method prior to antiviral therapy. We calculated the cumulative incidences of HBsAg seroclearance based on the anti-HBc IgG levels. RESULTS After a 10-year follow-up, 48 patients experienced HBsAg seroclearance (13.1%). Thirty-three of 179 patients who had an indirect ratio of light absorbance of anti-HBc IgG < 11 RLU (relative light unit) showed HBsAg seroclearance (18.4%); 15 of 187 patients who had an indirect ratio of light absorbance of anti-HBc IgG ≥ 11 RLU showed HBsAg seroclerance (8.0%) (p = 0.003). In multivariate analysis, age, and ALT at the time of HBeAg seroclearance were predictors of HBsAg seroclearance. Especially, the relative risk of HBsAg seroclearance in patients with baseline anti-HBc IgG levels < 11 RLU was 2.213 (95% CI, 1.220-4.014), compared to that in patients with higher levels of anti-HBc IgG at baseline (p = 0.009). CONCLUSION Using an indirect method for anti-HBc IgG levels, baseline anti-HBc IgG levels (< 11RLU), age (≥ 50 years), and ALT (≥ 40 IU/L) might be associated with HBsAg seroclearance in patients with NA-induced HBeAg seroclearance.

Abstract
Background Few models to predict antiviral response of peginterferon were used in hepatitis B e antigen (HBeAg)-positive chronic hepatitis B patients and the prediction efficacy was unsatisfied. Quantitative antibody to hepatitis B core antigen (anti-HBc) is a new predictor of treatment response. We aimed to develop a new model to identify HBeAg-positive Chinese patients who were more likely to respond to peginterferon. Methods Data from 140 peginterferon recipients with HBeAg-positive were applied with generalized additive models and multiple logistic regression analysis to develop a baseline scoring system to predict serological response (SR: HBeAg loss and HBeAg seroconversion 24 weeks post-treatment) and combined response (CR: SR plus serum HBV DNA levels <2000 IU/mL 24 weeks post-treatment). Results Anti-HBc levels, alanine aminotransferase ratio, and HBeAg were retained in the final model. The new model scored from 0 to 3. Among patients with scores of 0, 1, or ≥2, SR was achieved in 6.45% (2/31), 13.21% (7/51), and 55.36% (31/56), respectively, and CR in 3.23% (1/31), 9.43% (5/53), and 25.00% (14/56), respectively. Our model has a higher AUROC for SR comparing to Chan’s (Z = 2.77 > 1.96, p < 0.05) and Lampertico’s (Z = 2.06 > 1.96, p < 0.05) model. The negative predictive value for SR and CR were both 100% in patients with score 0 and hepatitis B surface antigen ≥20,000 IU/mL at week 12. Conclusions Patients with higher scores at baseline were more likely to respond to peginterferon. This new model may predict the treatment response.

Combination of quantitative hepatitis B core antibody (qHBcAb) and aspartate aminotransferase (AST) can accurately diagnose immune tolerance of chronic hepatitis B virus infection based on liver biopsy. Clin Res Hepatol Gastroenterol 2021; 45:101563. [PMID: 33272888 DOI: 10.1016/j.clinre.2020.10.008] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2020] [Accepted: 10/14/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND AND AIMS Immune tolerance is defined as HBeAg positive, high hepatitis B virus load (HBV), persistent normal alanine aminotransferase (ALT), no or slight inflammation or fibrosis in liver histology. However, it is still unclear the threshold of high hepatitis B virus load and how to predict histology without liver biopsy. The aim of this study was to predict immune tolerance in HBeAg positive, alanine aminotransferase -normal populations with non-invasive indicators. METHODS Two multi-center prospective cohort study recruited 907 treatment-naïve chronic hepatitis B (CHB) patients who had undergone liver biopsy in mainland China from August 2013 to September 2016 and April 2018 to June2019. Quantitative hepatitis B core antibody, AST and HBV DNA were investigated using commercial diagnostic assays and histological grading and staging was assessed by the Ishak scoring system. RESULTS One hundred and thirteen untreated CHB patients with HBeAg-positive, normal alanine aminotransferase (ALT) and high level of HBV DNA (≥5log10 IU/mL) were enrolled in this study. The area under the receiver operating characteristic curves (AUROCs) of qHBcAb, AST, HBV DNA and qHBcAb-AST index were 79.6%, 80.5%, 76.4% and 87.7%. Our novel qHBcAb-AST index, which combined qHBcAb and AST showed better performance with higher sensitivity (88.6% [95% confidence interval (CI) 72.3% - 96.3%]) and negative predictive value (NPV) (93.8% [95% CI 84.2% - 98.0%]). CONCLUSIONS The combination of qHBcAb and AST can more accurately predict the immune tolerance of people with HBeAg-positive, normal alanine aminotransferase (ALT).

Abstract
BACKGROUND AND AIMS Chronic hepatitis B is the main cause of liver cancer. However, the most neglected group has been treatment-naive chronic hepatitis B patients with normal alanine aminotransferase (ALT). People have tended to subjectively assume that the liver lesions of these patients are not serious and do not need antiviral treatment. However, the truth is not as optimistic as we thought. We aimed in this study to analyze the proportion of significant inflammation or fibrosis in aforementioned patients. METHODS Medline, Embase, and Cochrane Library were searched up to January 10th 2020, to identify studies of these patients with liver biopsy. The double arcsine method was used with a random-effect model to combine the proportion of significant inflammation or fibrosis. Potential heterogeneity was explored by subgroup analysis and meta-regression. Outcome of interests included the proportion of significant inflammation or fibrosis and cirrhosis. The secondary outcome was to find the risk factors of significant histological changes. RESULTS Nineteen eligible studies, with 2,771 participants, were included. The pooled proportion of significant inflammation or fibrosis was 35% [95% confidence interval (CI): 27 to 43] and 30% (95% CI: 25 to 36), respectively. The pooled proportion of cirrhosis was 3% [95% CI: 1 to 5, (12 studies; 1,755 participants)]. In subgroup analysis, old age [vs. young (<40 years-old), 44% vs. 26%, p=0.012] was significantly associated with higher fibrosis stage as well as cirrhosis [vs. young (<40 years-old), 4.8% vs. 1.8%, p<0.001]. CONCLUSIONS About 1/3 of the treatment-naive chronic hepatitis B patients with normal ALT show significant histological changes, and some even have cirrhosis.

Expression and clinical significance of inhibitory receptor Leukocyte-associated immunoglobulin-like receptor-1 on peripheral blood T cells of chronic hepatitis B patients: A cross-sectional study. Medicine (Baltimore) 2021; 100:e26667. [PMID: 34398030 PMCID: PMC8294879 DOI: 10.1097/md.0000000000026667] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2021] [Accepted: 06/29/2021] [Indexed: 01/04/2023] Open
Abstract
Leukocyte-associated immunoglobulin-like receptor-1 (LAIR-1) is an inhibitory receptor that is expressed on the surface of multiple immune cells and plays key roles in immune modulation. In patients with chronic hepatitis B (CHB), T cell number and functions are abnormal and the expression of inhibitory receptors is elevated. However, the expression of LAIR-1 on T cells in patients with CHB is still undetermined.We recruited 320 patients with CHB in different disease phases and 17 healthy donors. Serum biochemical and virological examinations were performed for each participant, and their demographic and clinical data were collected. According to the latest American Association for the Study of Liver Disease guidelines, we categorized the patients into 4 groups: immune active, immune tolerant, inactive CHB, and gray zone. Additionally, we tested the expression of LAIR-1 on T cells and T cell subsets using flow cytometry.We observed a significant decrease in LAIR-1 expression on CD3+ T cells and its two subsets (CD4+ and CD8+ T cells) in patients with CHB. LAIR-1 expression on T cells was the lowest in the immune active group. LAIR-1 expression levels on CD4+ and CD8+ T cells showed a significant negative association with hepatitis B virus (HBV) DNA load and were lower in hepatitis B e antigen (HBeAg)-positive patients than in HBeAg-negative patients (P < .05). In addition, LAIR-1 expression levels on CD3+, CD4+, and CD8+ T cells were all negatively associated with liver inflammation and fibrosis parameters, such as alanine aminotransferase and aspartate aminotransferase levels, FibroScan value, and aspartate aminotransferase-to-platelet ratio index score.LAIR-1 expression levels on T cells were associated with HBV DNA load and liver inflammation and fibrosis parameters, indicating that LAIR-1 may play an important regulatory role in HBV-induced T cell immune pathogenesis and may be a therapeutic target for CHB.

Abstract
BACKGROUND Clinical importance of commercially available quantitative HBV markers has not been fully investigated. OBJECTIVE To choice and to evaluate clinically valuable HBV markers for predicting phases of natural history with chronic HBV infection. METHODS 472 naïve patients with chronic HBV infection were enrolled, in which 21 and 220 were confirmed as HBeAg-positive inactive and active hepatitis (EPIH and EPAH), respectively, and 106 and 125 were confirmed as HBeAg-negative inactive and active hepatitis (ENIH and ENAH), respectively. HBsAg, HBcrAg and anti- HBc were measured using chemiluminescent immunoassay, and HBV DNA was measured using PCR-fluorescence probing assay. RESULTS There were all statistical differences in medians of HBsAg, anti-HBc, HBcrAg and HBV DNA between EPIH and EPAH and between ENIH and ENAH (all P < 0.01). According to binary logistic stepwise regressions, HBsAg and anti-HBc were preferred variables for predicting EPAH, and HBcrAg and HBV DNA were preferred variables for predicting ENAH. Based on normalization for coefficients of preferred variables entering regression equations, a handy model of MEPAH for predicting EPAH and of MENAH for predicting ENAH was constructed, respectively. Area under receiver operating characteristic curves of MEPAH and MENAH for predicting EPAH and ENAH were 0.882 and 0.931, respectively. With standard of MEPAH ≤ 5.997 and MENAH > 10.535, sensitivity or specificity of which for predicting EPAH and ENAH were about 81.0 % and 87.0 %, respectively. CONCLUSION HBsAg and anti-HBc for predicting EPAH and HBcrAg and HBV DNA for predicting ENAH are dependable markers; MEPAH for predicting EPAH and MENAH for predicting ENAH have very good performance.

Abstract
BACKGROUND AND AIM It has been reported that serum quantification of anti-HBc (qAnti-HBc) could predict antiviral response in chronic hepatitis B (CHB) patients, while its role in hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) remains unclear. Its implication in HBV-ACLF was evaluated in this study. METHODS Baseline serum qAnti-HBc levels were retrospectively detected in HBV-ACLF and CHB patients using recently developed double-sandwich immunoassay. The association of qAnti-HBc level with clinical outcomes was evaluated by multiple logistic regression. Nomogram was adopted to formulate an algorithm incorporating qAnti-HBc for the prediction of survival in HBV-ACLF. The post-hospitalization of HBV-ACLF patients were followed-up for 1 year. RESULTS Eighty-eight HBV-ACLF as training set, 80 HBV-ACLF as validation set and 216 CHB cases were included. Serum qAnti-HBc level was significantly higher in HBV-ACLF (4.95 ± 0.54 log10 IU/mL) than CHB patients (4.47 ± 0.84 log10 IU/mL) (P < 0.01). Among HBV-ACLF cases, both in training and validation set, patients with poor outcomes had lower qAnti-HBc level. Area under receiver operating characteristic curve of the novel qAnti-HBc inclusive model was 0.82, superior to 0.73 from model for end-stage liver disease scores (P = 0.018), which was confirmed in validation set. During follow-up, the qAnti-HBc level declined at month 3 and month 6, then plateaued at 3.84 log10 IU/mL. CONCLUSIONS Serum qAnti-HBc level was associated with disease severity and might be served as a novel biomarker in the prediction of HBV-ACLF clinical outcomes. The underlying immunological mechanism warrants further investigation.

Abstract
BACKGROUND Hepatitis B core-related antigen (HBcrAg) is a promising disease-monitoring marker for chronic hepatitis B (CHB). We investigated correlations between HBcrAg with antiviral efficacy and virological and histological variables. METHODS One hundred and forty-five CHB patients from the mainland of China between August 2013 and September 2016 who underwent liver biopsy received entecavir therapy and had paired liver biopsy at 78 weeks. We analyzed correlations between HBcrAg and virological and histological variables in hepatitis B e antigen (HBeAg)-positive and HBeAg-negative patients. We also explored the predictors of HBeAg loss after 78 weeks of antiviral therapy. Pearson correlation analysis and logistic forward stepwise regression were the main statistic methods. RESULTS HBeAg-positive patients (n = 93) had higher baseline HBcrAg (median 7.4 vs. 5.3 log10 U/mL P < 0.001) and greater HBcrAg declines (median 1.6 vs. 0.9 log10 U/mL P = 0.007) than HBeAg-negative patients after 78 weeks of therapy. At baseline, HBcrAg correlated with hepatitis B virus (HBV) DNA in both HBeAg-positive (r = 0.641, P < 0.001) and -negative patients (r = 0.616, P < 0.001), with hepatitis B surface antigen (HBsAg) in HBeAg-positive patients (r = 0.495, P < 0.001), but not with anti-hepatitis B virus core antibody (anti-HBc). Weak correlations existed between HBcrAg, histology activity index (HAI; r = 0.232, P = 0.025), and Ishak fibrosis score (r = -0.292, P = 0.005) in HBeAg-positive patients. At 78 weeks, significant correlations existed only between HBcrAg and anti-HBc in HBeAg-positive (r = -0.263, P = 0.014) and HBeAg-negative patients (r = -0.291, P = 0.045). Decreased HBcrAg significantly correlated with reduced HBV DNA (r = 0.366, P = 0.001; r = 0.626, P < 0.001) and HBsAg (r = 0.526, P = 0.001; r = 0.289, P = 0.044) in HBeAg-positive and -negative patients, respectively, and with reduced HAI in HBeAg-positive patients (r = 0.329, P = 0.001). Patients with HBeAg loss (n = 29) showed a larger reduction in HBcrAg than those without (median 2.3 vs. 1.3 log10 U/mL, P = 0.001). In multivariate analysis, decreased HBcrAg was an independent predictor of HBeAg loss (P = 0.005). CONCLUSIONS HBcrAg reflects viral replication and protein production. Decreased HBcrAg could predict HBeAg loss after antiviral therapy.

Significant histological changes and satisfying antiviral efficacy in chronic hepatitis B virus infection patients with normal alanine aminotransferase. Antiviral therapy decision in chronic HBV patients with normal ALT. Clin Res Hepatol Gastroenterol 2021; 45:101463. [PMID: 32571749 DOI: 10.1016/j.clinre.2020.05.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Accepted: 05/06/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND AIMS A proportion of chronic hepatitis B virus (HBV) infection patients with normal alanine aminotransferase (ALT) should start antiviral therapy based on liver biopsy. We aim to evaluate the proportion of such patients, find noninvasive methods for identifying and then evaluate antiviral efficacy. METHODS 253 chronic HBV infection patients with normal ALT were analyzed at baseline and 57 patients with histological indication for antiviral therapy (Histology activity index ≥5 and/or Ishak fibrosis score ≥3) and 140 patients with elevated ALT received entecavir therapy and were followed-up to 78 weeks with a second liver biopsy in this multi-center study. RESULTS 127 (50.2%) of 253 patients with normal ALT fulfilled histological indication for antiviral therapy. Aspartate aminotransferase (P=0.049), anti-hepatitis B virus core antibody (P=0.001) and liver stiffness measurement (P=0.000) were independent variables for identifying histological indication for antiviral therapy. A noninvasive model (AAF) performed best among independent variables and other noninvasive models with area under the operating characteristic curve of 0.887. Antiviral efficacy showed that 38 (66.7%) of 57 patients had undetectable HBV DNA. 12 (41.4%) of 29 patients who were hepatitis B e antigen (HBeAg)-positive at baseline achieved HBeAg loss and 3 (10.3%) achieved HBeAg seroconversion. 25 (43.9%) of 57 patients achieved histological response. Moreover, 57 patients with normal ALT had a similar antiviral therapy efficacy with 140 patients with elevated ALT (P>0.1) except proportion of inflammation improvement and histological response (P=0.005, P=0.049). CONCLUSIONS Half of chronic HBV patients with normal ALT should start antiviral therapy based on liver biopsy. A noninvasive model could be used as a reliable tool for antiviral therapy decision. Patients with normal or elevated ALT had a similar antiviral efficacy.

Abstract
Chronic hepatitis B virus (HBV) infection encompasses a wide virologic and clinical spectrum with heterogeneous outcomes. The natural history of chronic HBV infection ranges from an inactive carrier state (hepatitis B e antigen-negative chronic infection) to progressive chronic hepatitis that may evolve in end-stage liver disease and hepatocellular carcinoma. The issue becomes even more complicated when we consider the unique biology of the virus; the HBV covalently-closed-circular DNA, that acts as virus transcription template, is the key factor responsible of the persistence of the infection even after hepatitis B surface antigen loss. In the last decade, novel serological and immunological biomarkers associated to the core protein of HBV have been approached in different clinical conditions. Remarkable results have been obtained both in the setting of overt and occult HBV infection. Here, we reviewed the meaning and the potential clinical applications of the measurement of core antigen and antibodies.

Abstract
Little data exist on basal core promoter/precore (BCP/PC) mutations in chronic hepatitis B (CHB) patients at the immune-tolerance (IT) phase. We studied consecutive treatment-naïve, CHBe-antigen (HBeAg)-positive patients who had undergone liver biopsy and genotyping. Those in the IT phase or immune-clearance (IC) phase were enrolled for comparison of the frequency of BCP/PC mutations and their clinical presentations. Subgroup analyses for the IT group were also performed between patients with and without mutations, and IC patients between fibrosis stages ≤2 vs fibrosis >2. Among 301 patients enrolled, 88/301 (29.24%) and 213/301 (70.76%) were at the IT and IC phase, respectively. The frequency of BCP/PC mutations in IT phase was significantly lower than those in IC phase (15.91% vs 64.79%, P < .001). The BCP mutation only was significantly more frequent than the PC mutation in both groups and also in all IC subgroups. IT patients with BCP/PC mutations had significantly higher quantitative anti-HBc levels compared with those of patients with wild-type virus (P < .05). They also had significantly lower mean levels of alanine transaminase, aspartate transaminase, total bilirubin and qAnti-HBc compared with those of IC patients (all P < .05). Additionally, they were significantly younger in mean age, had higher platelet count, higher levels of HBV DNA and surface antigen, as well as higher frequency of genotype B than those of IC patients with fibrosis >2 (all P < .05). BCP/PC mutations were found in IT patients with CHB. They had distinct clinical characteristics when compared with patients with wild-type or at IC phase. Further studies are needed to understand their natural history and treatment outcomes.

Abstract
Chronic hepatitis B virus (HBV) infection affects 292 million people worldwide and is associated with a broad range of clinical manifestations including cirrhosis, liver failure, and hepatocellular carcinoma (HCC). Despite the availability of an effective vaccine HBV still causes nearly 900,000 deaths every year. Current treatment options keep HBV under control, but they do not offer a cure as they cannot completely clear HBV from infected hepatocytes. The recent development of reliable cell culture systems allowed for a better understanding of the host and viral mechanisms affecting HBV replication and persistence. Recent advances into the understanding of HBV biology, new potential diagnostic markers of hepatitis B infection, as well as novel antivirals targeting different steps in the HBV replication cycle are summarized in this review article.

Abstract
AIMS Interleukin-35 (IL-35) is a new member of the interleukin-12 family and is composed of the P35 and EB virus-inducible gene 3 subunits. The aims of this study were to examine the roles of IL-35 in the exhaustion of HBV-specific CTLs, as little as known on the subject. MAIN METHODS The relative levels of serum HBV markers were detected using automated biochemical techniques. The HBV DNA copies were measured by RT-qPCR. The expression of inhibitory receptors and the cell cytokines on the surface of CTLs were determined by flow cytometry. The pSTAT1-pSTAT4 protein levels expression was determined by flow cytometry, confocal microscopy and Western blot. KEY FINDINGS Our results showed that IL-35 can activate the Janus kinase 1 (JAK1)/tyrosine kinase 2 (TYK2)/signal transducer and activator of transcription 1 (STAT1)/STAT4 pathway in CTLs in vitro. Interferon-γ and tumor necrosis alpha-α expression increased in CTLs in the presence of a JAK/STAT-pathway blocker. In addition, we evaluated the expression of the exhaustion-associated molecules programmed death-1, cytotoxic T lymphocyte-associated protein-4, and lymphocyte activation gene-3 in CTLs after adding the JAK-STAT inhibitor The results showed that the expression of exhaustion-associated molecules on the CTL surface decreased after blocking the JAK-STAT pathway. IL-35 inhibited the function of HBV-specific CTLs through the JAK1/TYK2/STAT1/STAT4 pathway, and the function of CTLs was recovered after blocking the JAK/STAT pathway. SIGNIFICANCE These data provide a new experimental basis for immunotherapy for chronic hepatitis B.

Abstract
Hepatitis B virus (HBV) infection is prevalent worldwide and is associated with dramatic levels of morbidity and mortality. Isolated anti-HBc (IAHBc) is a particular serological pattern that is commonly found in immunocompromised patients. There is ongoing debate regarding the management of patients with IAHBc. Herein, we summarize the current guidelines and the newest evidence. The frequency of IAHBc is variable, with a higher prevalence in some populations, such as persons living with HIV and others immunocompromised patients. The risk of HBV reactivation depends on host factors (including immunosuppression) and viral factors. It is now well established that immunocompromised patients can be classified into three groups for risk according to the type of immunosuppression and/or treatment. In patients at high risk, HBV therapy has to be considered systematically. In patients at moderate risk, the decision is based on the level of HBV DNA (preemptive treatment or monitoring and vaccination). In patients with low risk, HBV vaccination is another possible approach, although further studies are needed to assess the type of preemptive strategy.

Abstract
Background Changes of hepatitis B core antigen antibody (anti-HBc) in liver pathological involvement in patients with chronic hepatitis B virus (HBV) infection have not been investigated in detail. This study aimed to explore evolving patterns of anti-HBc following liver pathological states and to investigate validities of anti-HBc for predicting liver pathological states. Methods 254 HBeAg-positive and 237 HBeAg-negative patients with chronic HBV infection were enrolled. Liver pathological diagnoses referred to Scheuer standard, and anti-HBc was measured using chemiluminescence microparticle immunoassay. Results Anti-HBc was significantly positively correlated with pathological grades and stages in both HBeAg-positive (rs = 0.312, P < 0.0001, and rs = 0.268, P < 0.0001) and HBeAg-negative (rs = 0.270, P < 0.0001, and rs = 0.147, P=0.0237) patients. The medians of anti-HBc in pathological grades of G1, G2, and G3 and stages of S1, S2, S3, and S4 in HBeAg-positive patients were all significantly lower than those in HBeAg-negative patients (all P < 0.005). The areas under receiver-operating characteristic curves (95% confidence interval) of anti-HBc for predicting pathological grades ≥G2 and ≥G3, and stages ≥S2 and =S4 in HBeAg-positive patients were 0.683 (0.622–0.740) and 0.662 (0.601–0.720), and 0.627 (0.564–0.687) and 0.683 (0.622–0.740), respectively, and in HBeAg-negative patients were 0.681 (0.618–0.740) and 0.702 (0.639–0.760), and 0.569 (0.503–0.633) and 0.630 (0.565–0.691), respectively. Conclusion Following hepatic aggravation of necroinflammation and progression of fibrosis, anti-HBc increases gradually in HBeAg-positive patients and continues to increase gradually in HBeAg-negative patients, which is a useful but unsatisfactory marker for monitoring pathological states.

Abstract
Purpose Angiopoietin-like protein 2 (ANGPTL2) is a secretory glycoprotein with various functions in vascular biology, inflammation and tumor development. As shown in our previous studies, ANGPTL2 expression positively correlates with liver fibrosis stages in chronic hepatitis B (CHB) patients. The aim of this study was further to assess whether ANGPTL2 represents a potential biomarker for detecting hepatocellular carcinoma (HCC). Patients and methods This study enrolled 361 participants including healthy controls (HCs) and patients with CHB, liver cirrhosis (LC) and HCC. A discovery cohort consisted of 35 HCs and 55 patients with HCC. A total of 271 participants, including 45 HCs, 125 patients with CHB, 38 patients with LC, and 63 patients with HCC were enrolled in a validation cohort. Serum ANGPTL2 levels were detected using a human ANGPTL2 assay kit, and hepatic expression of ANGPTL2 was analyzed using immunohistochemistry. Results In the discovery cohort, a significantly higher serum ANGPTL2 level was detected in HCC than in HCs (73.49±33.87 vs 30.54±9.86; p<0.001). The results of the receiver operating characteristic curve indicated a significantly higher area under the curve for the ability of the ANGPTL2 to predict HCC than alpha fetoprotein (AFP). In the validation cohort, serum ANGPTL2 level gradually increased with the progression of chronic hepatitis B virus infection and reached the highest level in HCC. Immunohistochemical staining also confirmed these findings. The serum ANGPTL2 displayed better diagnostic efficiency not only for differentiating HCC from HC but also for differentiating HCC from high-risk controls (CHB+LC). Furthermore, the combination of ANGPTL2 and AFP may increase the diagnostic accuracy for HCC compared to ANGPTL2 or AFP alone. Importantly, ANGPTL2 levels also correlated with the detection of AFP-negative HCC. Conclusions ANGPTL2 may be used as a promising biomarker for the diagnosis of CHB-related HCC.

Abstract
Liver biopsy is the reference method for antiviral therapy decision-making in chronic hepatitis B (CHB) when alanine aminotransferase (ALT) is less than two times of upper limit of normal (<2ULN). Our aim was to explore noninvasive markers for antiviral therapy decision in CHB with ALT <2ULN. A total of 452 treatment-naïve CHB patients with ALT < 2ULN who had undergone liver biopsy were analysed in this prospective multi-centre study. If liver biopsy showed moderate or severe inflammation (histology activity index ≥ 5) or significant fibrosis (Ishak fibrosis score ≥ 3), antiviral treatment was recommended. We analysed data using univariate and multivariate analyses and receiver operating characteristic curves (ROC). Two hundred and sixty-nine (59.5%) of 452 cases with ALT < 2ULN had moderate, severe or significant inflammation. Aspartate aminotransferase (AST) (P = 0.03), anti-hepatitis B virus core antibody (anti-HBc) (P = 0.003) and liver stiffness measurement (LSM) (P = 0.000) were independent variables for antiviral therapy decision-making, with area under the ROC curve (AUROC) of 0.718, 0.703 and 0.819, respectively. Our novel AAF index, which combined AST, anti-HBc and LSM, showed better performance with AUROC of 0.876, 0.877 and 0.876 in estimation, validation and total set. Finally, 247 (54.6%) of 452 patients could avoid liver biopsy based on AAF index. Furthermore, performances of 23 noninvasive models were unsatisfactory for antiviral therapy decision with AUROC < 0.800, which were inferior to AAF index. In conclusion, AST, anti-HBc and LSM were related to antiviral therapy decision-making among CHB patients with ALT < 2ULN. Thus, the novel AAF index was a more reliable noninvasive model for antiviral therapy decision-making.

Level of Hepatitis B (HB) Core Antibody Associates With Seroclearance of HBV DNA and HB Surface Antigen in HB e Antigen-Seronegative Patients. Clin Gastroenterol Hepatol 2019; 17:172-181.e1. [PMID: 29753083 DOI: 10.1016/j.cgh.2018.04.064] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2017] [Revised: 03/31/2018] [Accepted: 04/21/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Although a low level of hepatitis B surface antigen (HBsAg) is a marker of hepatitis B virus (HBV) seroclearance, additional biomarkers are needed for more accurate prediction. We investigated whether quantification of antibody against HBV core protein (anti-HBc) can identify patients with undetectable levels of HBV DNA and HBsAg seroclearance among those who were HBV e antigen (HBeAg)-seronegative. METHODS We performed a retrospective analysis of data from a community-based cohort of individuals (30-65 years old) in Taiwan who were HBsAg seropositive, anti-HCV negative, and free of cirrhosis and/or liver cancer, recruited from 1991 through 1992, and evaluated every 6-12 months until June 30, 2004. We measured levels of anti-HBc in blood samples from 2500 participants who were seronegative for HBeAg. The first date at which a sample tested negative for HBV DNA or HBsAg, and remained negative in subsequent tests, was designated as the date of spontaneous HBV DNA undetectability or HBsAg seroclearance. We calculated cumulative incidences of HBV DNA undetectability and HBsAg seroclearance; associations between level of anti-HBc and undetectability of HBV DNA or HBsAg seroclearance were estimated by Cox proportional hazard regression. The effects of time on the associations between level of anti-HBc and HBsAg seroclearance was assessed by the area under the receiver operating characteristic curve (AUROC) analysis. RESULTS After a 12-year follow-up period, higher proportions of subjects with levels of anti-HBc <3 log IU/mL had undetectable levels of HBV DNA (58%) and HBsAg seroclearance (53%) than subjects with higher levels of anti-HBc (29.6% and 19.8%, respectively) (P < .001). For subjects with levels of HBsAg <102 IU/mL and anti-HBc <3 log IU/mL, the adjusted rate ratio of HBV DNA undetectability was 16.45 (95% CI, 11.15-24.28) and of HBsAg seroclearance was 17.95 (95% CI, 12.49-25.81), compared to subjects with higher levels of HBsAg and anti-HBc. A model that included level of anti-HBc as a parameter identified subjects with HBsAg seroclearance within 10 years with an AUROC of 82%; this value was significantly higher than that from models that include only level of HBV DNA and HBsAg (P < .0001). CONCLUSIONS In a retrospective analysis of a large cohort of patients with chronic HBV infection in Taiwan, we associated levels of anti-HBc <3 log IU/mL with undetectable HBV DNA and HBsAg seroclearance occurred within 10 years; patients who also have levels of HBsAg <102 IU/mL have greater odds. Combining data on levels of HBsAg, HBV DNA, and anti-HBc is able to identify HBeAg-seronegative patients who can achieve HBsAg seroclearance with an AUROC value of 82%.

Performance of Hepatitis B Core-Related Antigen Versus Hepatitis B Surface Antigen and Hepatitis B Virus DNA in Predicting HBeAg-positive and HBeAg-negative Chronic Hepatitis. Ann Lab Med 2018; 39:67-75. [PMID: 30215232 PMCID: PMC6143474 DOI: 10.3343/alm.2019.39.1.67] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2017] [Revised: 04/08/2018] [Accepted: 08/20/2018] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND We examined changes in hepatitis B core-related antigen (HBcrAg) during the four sequential phases of chronic hepatitis B virus (HBV) infection: hepatitis B e antigen (HBeAg)-positive chronic infection (EPCI) and hepatitis (EPCH), followed by HBeAg-negative chronic infection (ENCI) and hepatitis (ENCH). We compared the performance of serum HBcrAg, hepatitis B surface antigen (HBsAg), and HBV DNA in predicting EPCH and ENCH. METHODS We enrolled 492 consecutive patients: 49 with EPCI, 243 with EPCH, 101 with ENCI, and 99 with ENCH. HBcrAg was detected by chemiluminescent enzyme immunoassays. HBsAg and HBeAg were detected by chemiluminescent microparticle immunoassays. HBV DNA was detected by real-time PCR. Predictive performance of HBcrAg, HBsAg, and HBV DNA was evaluated using ROC curves. RESULTS Areas under ROC curves (AUCs) of HBcrAg, HBsAg, and HBV DNA for predicting EPCH were 0.738, 0.812, and 0.717, respectively; optimal cutoffs were ≤1.43×10⁵ kU/mL, ≤1.89×10⁴ IU/mL, and ≤3.97×10⁷ IU/mL, with sensitivities and specificities of 66.3% and 77.6%, 65.0% and 93.9%, and 60.5% and 79.6%, respectively. AUCs of HBcrAg, HBsAg, and HBV DNA for predicting ENCH were 0.887, 0.581, and 0.978, respectively; optimal cutoffs were >26.8 kU/mL, >2.29×10² IU/mL, and >8.75×10³ IU/mL, with sensitivities and specificities of 72.7% and 95.1%, 86.9% and 39.6%, and 89.9% and 92.1%, respectively. CONCLUSIONS HBsAg and HBV DNA were the best predictors of EPCH and ENCH, respectively. HBcrAg is an important surrogate marker for predicting EPCH and ENCH.

Quantification of HBV core antibodies may help predict HBV reactivation in patients with lymphoma and resolved HBV infection. J Hepatol 2018; 69:286-292. [PMID: 29551710 DOI: 10.1016/j.jhep.2018.02.033] [Citation(s) in RCA: 66] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2017] [Revised: 02/13/2018] [Accepted: 02/26/2018] [Indexed: 12/17/2022]
Abstract
BACKGROUND & AIMS Absence or low anti-HBV surface antibody (anti-HBs) is associated with an increased risk of HBV reactivation in patients with lymphoma and resolved HBV infection receiving rituximab-containing chemotherapy. Quantification of anti-HBV core antibody (anti-HBc) is a new marker associated with the natural history and treatment response of chronic HBV infection. This study investigated whether baseline anti-HBc and anti-HBs levels may better predict HBV reactivation. METHODS We prospectively measured the HBV DNA levels of patients with lymphoma and resolved HBV infection receiving rituximab-cyclophosphamide, hydroxydaunorubicin, vincristine, and prednisolone-based chemotherapy and started an antiviral therapy upon HBV reactivation, defined as a greater than 10-fold increase in HBV DNA compared with previous nadir levels. Anti-HBs and anti-HBc were quantified by a double-sandwich assay. Receiver-operating-characteristic-curve analysis was used to determine the optimal baseline anti-HBc/anti-HBs levels for predicting HBV reactivation. RESULTS HBV reactivation occurred in 24 of the 197 patients enrolled, with an incidence of 11.6/100 person-years. For the 192 patients with enough serum samples for analysis, low anti-HBs (<56.48 mIU/ml) and high anti-HBc (≥6.41 IU/ml) at baseline were significantly associated with high risk of HBV reactivation (hazard ratio [HR] 8.48 and 4.52, respectively; p <0.01). The multivariate analysis indicated that (1) patients with both high anti-HBc and low anti-HBs at baseline (36 of 192 patients) had an HR of 17.29 for HBV reactivation (95% CI 3.92-76.30; p <0.001), and (2) HBV reactivation may be associated with inferior overall survival (HR 2.41; 95% CI 1.15-5.05; p = 0.02). CONCLUSIONS Baseline anti-HBc/anti-HBs levels may predict HBV reactivation in these patients with lymphoma and help optimize prophylactic antiviral therapy for high-risk patients. LAY SUMMARY In this study, we identified a subgroup of patients with lymphoma and resolved hepatitis B virus infection that had a high risk of hepatitis B virus reactivation after receiving rituximab-containing chemotherapy. These findings will help optimize a preventive strategy, especially in hepatitis B virus endemic regions with limited healthcare resources. Clinical trial number: NCT 00931229.

Abstract
Hepatitis B core antibody (anti-HBc) is considered the most sensitive serological marker for history of hepatitis B virus (HBV) infection. In a subset of anti-HBc carriers, anti-HBc is present in the absence of hepatitis B surface antigen and hepatitis B surface antibody-a serological pattern known as "isolated anti-HBc" (IAHBc). IAHBc has been of clinical interest over the past several years, with growing data to suggest its role as a serological marker for occult HBV infection (OBI). This article reviews the clinical significance and association of IAHBc with hepatitis C virus (HCV) co-infection, risk of HBV reactivation during direct-acting antiviral therapy for HCV as well as immune suppression, and development of hepatocellular carcinoma (HCC). Hepatitis B core-related antigen is also highlighted as an emerging laboratory assay that may identify OBI and predict HCC development in non-cirrhotic patients receiving nucleoside/nucleotide analog therapy.

Abstract
Chronic hepatitis B (CHB) exhibits a variety of clinical outcomes, ranging from spontaneous resolution of hepatitis B to severe adverse consequences, including the development of cirrhosis, hepatic failure, and hepatocellular carcinoma. The heterogeneous clinical courses of chronic hepatitis B virus (HBV) infection reflect the complex host-virus interactions, and point to the difficulty and necessity of identifying the patients at risk. With the advance of HBV virology, several viral factors have been found to be associated with the long-term clinical outcomes of CHB patients. Different viral factors probe different aspects of CHB. Integration of these viral factors may help to determine the disease state of patients more accurately, and identify the patients who require timely antiviral therapy to prevent the development of detrimental clinical outcomes. In this article, we will introduce the conventional and emerging viral factors that are associated with clinical outcomes and discuss their utility in a clinical setting.

Abstract
Background For hepatitis B patients who do not meet the treatment criteria recommended by guidelines, therapy decisions depend on hepatic histology. Angiopoietin-like protein 2 (Angptl2) is a mediator of chronic inflammation that contributes to extracellular matrix remodeling. The aim of this study was to explore the predictive value of Angptl2 as a novel biomarker of liver histology. Methods Hepatitis B patients with normal to minimally raised ALT were recruited. Serum Angptl2 concentrations were detected using commercial ELISA kit. The fibrosis score were assessed according to Ishak criteria. Significant fibrosis was defined as ISHAK score ≥ 3. Results Of 460 patients, 223 cases served as training cohort and 237 ones as validation cohort. Serum Angptl2 concentration was significantly associated with fibrosis scores in both training and validation group. Angptl2 combined index (ACI) for assessing significant fibrosis was developed from training cohort, based on Angptl2 and conventional variables. ACI showed areas under receiver-operating characteristic curve (AUC) of 0.835 for predicting significant fibrosis, which was superior to APRI (AUC = 0.776, P = 0.049), FIB-4 (AUC = 0.750, P = 0.010), Hui model (AUC = 0.756, P = 0.028), and had a better trend than Forn’s index (AUC = 0.796, P = 0.083) in training cohort. Finally, validation cohort revealed its robustness and reliability. Conclusion Higher Angptl2 level represents as a potential biomarker independently associated with fibrosis stages. Compared with APRI, Hui model, FIB-4, Forn’s index, ACI did better in diagnosing significant fibrosis in hepatitis B patients.

Abstract
Background Previous studies have revealed that hepatitis B core antibody (anti-HBc) levels vary throughout the different phases of treatment-naïve chronic hepatitis B (CHB) patients and can be used as a predictor of treatment response in both interferon-α and nucleoside analogue therapies. However, few data have been published regarding the relationship between quantitative anti-HBc (qAnti-HBc) levels and liver fibrosis in patients with CHB. Results A total of 489 HBeAg-positive (HBeAg (+)) and 135 HBeAg-negative (HBeAg (−)) patients were recruited. In both HBeAg (+) and HBeAg (−) groups, the S0−1/S0 subjects had significantly lower qAnti-HBc levels than the S2−4 subjects (p < 0.05). Multiple logistic regression analysis showed that the parameters for predicting significant fibrosis (S ≥ 2) included age, PLT and qAnti-HBc. In HBeAg (+) subjects, the AUROC of qAnti-HBc for predicting significant fibrosis was 0.734 (95% CI 0.689 to 0.778) and the optimal cut-off was 4.58 log10IU/mL, with a sensitivity of 63.08% and a specificity of 74.83%. In HBeAg (−) subjects, the AUROC was 0.707 (95% CI 0.612 to 0.801) and the optimal cut-off value was 4.37 log10IU/mL, with a sensitivity of 75.53% and a specificity of 56.10%. Materials and Methods From 2012 to 2015, we conducted a cross-sectional study of treatment-naïve CHB patients. Liver biochemistry, hepatitis B virus (HBV) serological markers, HBV DNA, hepatitis B surface antigen (HBsAg) titers and HBV genotype were determined using commercial assays, and serum qAnti-HBc levels were measured using double-sandwich immunoassay. Liver biopsies and serum samples were obtained on the same day. Conclusions The present study showed an association between high serum qAnti-HBc levels and significant fibrosis (S ≥ 2) in treatment-naïve CHB patients. Furthermore, we described a serum qAnti-HBc cut-off for predicting significant fibrosis in CHB patients infected with HBV genotype B or C.

Our previous studies unexpectedly indicated that the level of serum hepatitis B core antibody (anti-HBc) was positively correlated with the serum alanine aminotransferase (ALT) level. The aim of this study was to determine whether anti-HBc could serve as a potential biomarker for the detection of liver inflammation in chronic hepatitis B (CHB) patients, especially in patients with normal ALT levels. Serum anti-HBc levels were quantified in 655 treatment-naïve CHB patients, including 45 patients who underwent two liver biopsies (baseline phase and the 78th weeks of antiviral-treatment). Serum anti-HBc levels increased significantly along with the increasing histology activity index (HAI) score. After antiviral-treatment, patients with HAI score reduction had significant decline in serum anti-HBc level. Multivariate analysis showed that anti-HBc was independently associated with moderate-to-severe hepatic inflammation in patients with normal ALT level. Furthermore, serum anti-HBc showed a high diagnostic accuracy for predicting moderate-to-severe inflammation in both hepatitis B e antigen (HBeAg)-positive and HBeAg-negative CHB patients with normal ALT levels (area under the curve, AUC = 0.87 and 0.75; respectively). Thus, anti-HBc may be a strong indicator for assessing the hepatic inflammatory degree and used for antiviral treatment decisions in CHB patients with normal ALT levels.

Abstract
With recent advances in molecular and genomic investigations, the impact of hepatitis B viral and host factors on the progression of chronic HBV infection has been explored. For viral factors, hepatitis B viral load is a strong predictor for liver disease progression. Hepatitis B viral kinetics appear to be important for successful anti-viral therapy. Serum HBsAg level serves as a complementary marker to viral load for the prediction of HBV-related adverse outcomes in patients with low viral load. In those with low viral load, high serum HBsAg level is associated with higher risks of cirrhosis and HCC. Hepatitis B core-related antigen (HBcrAg) induces host immune responses, and the reduction of the HBcrAg level as well as the increment of total anti-HBc level are significantly associated with favorable outcomes. HBV genotypes (genotype C/D) and mutants (basal core promoter and deletion mutation in pre-S genes) are well known viral genetic markers to predict disease progression. For host factors, serum inflammatory biomarkers have been developed to evaluate the HBV-associated hepatic necroinflammation and fibrosis. Host single nucleotide polymorphism on sodium taurocholate cotransporting polypeptide (NTCP, an HBV entry receptor) may be associated with a decreased risk for cirrhosis and HCC. In conclusion, patients with chronic hepatitis B should be evaluated with relevant viral and host markers to identify those who are at a higher risk of liver disease progression and then receive timely antiviral therapy.

Abstract
Previous studies have shown that hepatitis B core antibody (anti-HBc) levels vary during different phases of disease in treatment-naïve chronic hepatitis B (CHB) patients and can be used as a predictor of both interferon-α and nucleoside analogue therapy response. However, there is no information on the association between the quantitative serum anti-HBc (qAnti-HBc) level and liver inflammation in CHB patients. Therefore, we investigated these relationships in a large cohort of treatment-naïve CHB patients. A total of 624 treatment-naïve CHB patients were included in the study. The serum qAnti-HBc level was moderately correlated with ALT and AST levels (P < 0.001) in both hepatitis B e antigen-positive (HBeAg [+]) and HBeAg-negative (HBeAg [-]) CHB patients. CHB patients with no to mild inflammation (G0-1) had significantly lower serum qAnti-HBc levels than patients with moderate to severe inflammation (G2-4) (P < 0.001). Receiver operating characteristic analysis suggested that a serum qAnti-HBc cut-off value of 4.36 log10 IU/mL provided a sensitivity of 71.68%, specificity of 73.81%, positive predictive value of 78.43%, and negative predictive value of 66.24% in HBeAg (+) CHB patients with moderate to severe inflammation (G≥2). A cut-off value of 4.62 log10 IU/mL provided a sensitivity of 54.29%, specificity of 90.00%, positive predictive value of 95.00%, and negative predictive value of 36.00% in HBeAg (-) CHB patients with moderate to severe inflammation (G≥2). Serum qAnti-HBc levels were positively associated with liver inflammation grade. Furthermore, we identified optimal serum qAnti-HBc cut-off values for the prediction of inflammation activity in both HBeAg (+) and HBeAg (-) treatment-naïve CHB patients.

Abstract
There are only two currently approved classes of hepatitis B virus (HBV) antiviral agents, pegylated interferon (Peg-IFN), and nucleos(t)ide analogs (NAs) for chronic HBV infection. Although Peg-IFN is used for a finite 48-week duration and offers a greater chance of sustained off-treatment virological response, it is poorly tolerated and can only be offered to selected patients. The NAs are well tolerated but require prolonged therapy due to risk of relapse with treatment cessation. There is evolving data that novel virological assays (e.g., quantitative hepatitis B surface antigen, quantitative hepatitis B core antigen, quantitative antibody to core protein) in combination with hepatitis B genotype and more sensitive HBV DNA polymerase chain reaction (PCR) assays may be useful to predict response to IFN as well as off-treatment NA durability. Utilization of these clinical laboratory tests may be important given the development of novel anti-HBV therapies, hoping to achieve a cure for chronic hepatitis B infection.

Abstract
OBJECTIVES Few studies have investigated serum levels of platelet-derived growth factor (PDGF) in patients with chronic hepatitis B (CHB). The present study aimed to determine whether PDGF-BB could serve as a potential biomarker for the detection of liver fibrosis. METHODS From October 2013 to August 2015, 465 patients with CHB were enrolled prospectively in this study. All patients underwent liver biopsy and staging based on the Ishak system. The serum PDGF-BB level was measured quantitatively by ELISA. RESULTS The serum PDGF-BB level was negatively correlated with fibrosis stage in all patients (p = 0.003, Spearman's rho=-0.16) and was significantly different between fibrosis stages. The areas under the receiver operating characteristics curves (AUROCs) for serum PDGF-BB level and PGT score (a combination of PDGF-BB, gamma-glutamyl transpeptidase, and platelet levels) were 0.667 and 0.831, respectively, for patients with significant fibrosis and normal alanine aminotransferase (ALT) levels. The AUROCs for aspartate aminotransferase-to-platelet ratio (APRI) and fibrosis index based on four factors (FIB-4) were 0.823 and 0.821, respectively. Importantly, a cut-off value of 1.05 and 1.43, respectively, resulted in a sensitivity of 0.95 and 0.52, a specificity of 0.29 and 0.95, a positive predictive value of 0.30 and 0.79, and a negative predictive value of 0.96 and 0.86. The rate of correct diagnosis was up to 88.4% when using cut-offs of 1.05 and 1.43 for the absence or presence of significant fibrosis, respectively. CONCLUSIONS Serum PDGF-BB decreased remarkably as fibrosis progressed, and this could be used as a non-invasive biomarker for the assessment of fibrosis stage in patients with CHB.

Dynamics of Genotypic Mutations of the Hepatitis B Virus Associated With Long-Term Entecavir Treatment Determined With Ultradeep Pyrosequencing: A Retrospective Observational Study. Medicine (Baltimore) 2016; 95:e2614.

Abstract
The aim of the study is to explore the evolution of genotypic mutations within the reverse transcriptase region in partial virological responders (PVRs) receiving long-term entecavir (ETV) treatment. A total of 32 patients were classified as completely virological responders (CVRs) (n = 12) or PVRs (n = 20). Five partial responders were hepatitis B virus (HBV)-DNA positive after long-term therapy, which lasted for >3 years. A total of 71 serum samples from these 32 patients were assayed by ultra-deep pyrosequencing (UDPS): 32 samples were from all patients at baseline, and 39 were from PVRs with sequential inter-treatment. Approximately 84,708 sequences were generated per sample. At baseline, the quasispecies heterogeneity did not significantly differ between the 2 groups. The frequencies of substitutions indicating pre-existence of nucleos(t)ide analog resistant (NAr) mutants ranged from 0.10% to 6.70%, which did not statistically differ between groups either. However, the substitutions associated with the NAr mutants were significantly different from those associated with the non-NAr mutants in 13 patients; 6 of these patients were PVRs and the others were CVRs. Five patients were HBV DNA positive after regular ETV monotherapy for >3 years, and 4 of these patients underwent mild NAr substitution fluctuations (<20%). One patient developed virological breakthrough while bearing single, double, and triple (rtL180 M, rtM204 V, rtS202G) substitutions. In addition to the common substitutions, unknown amino acid substitutions, such as rtL145 M/S, rtF151Y/L, rtR153Q, rtI224 V, rtN248H, rtS223A, rtS256C, need to be further verified. NAr substitutions are observed at frequencies of 0.10% to 6.7% before therapy. Long-term ETV therapy generally results in virological responses, as long as the proportion of resistance mutations remains at a relatively low level. Genotypic resistance to ETV is detected in all PVRs receiving long-term ETV therapy.
