Both middle and large envelope proteins can mediate neutralization of hepatitis B virus infectivity by anti-preS2 antibodies: escape by naturally occurring preS2 deletions. J Virol 2024; 98:e0192923. [PMID: 39078152 PMCID: PMC11334434 DOI: 10.1128/jvi.01929-23] [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: 12/09/2023] [Accepted: 07/02/2024] [Indexed: 07/31/2024] Open
Abstract
Hepatitis B virus (HBV) expresses co-terminal large (L), middle (M), and small (S) envelope proteins containing preS1/preS2/S, preS2/S, and S domain alone, respectively. S and preS1 domains mediate sequential virion attachment to heparan sulfate proteoglycans and sodium taurocholate cotransporting polypeptide (NTCP), respectively, which can be blocked by anti-S and anti-preS1 antibodies. How anti-preS2 antibodies neutralize HBV infectivity remains enigmatic. The late stage of chronic HBV infection often selects for mutated preS2 translation initiation codon to prevent M protein expression, or in-frame preS2 deletions to shorten both L and M proteins. When introduced to infectious clone of genotype C or D, both M-minus mutations and most 5' preS2 deletions sustained virion production. Such mutant progeny viral particles were infectious in NTCP-reconstituted HepG2 cells. Neutralization experiments were performed on the genotype D clone. Although remaining susceptible to anti-preS1 and anti-S neutralizing antibodies, M-minus mutants were only partially neutralized by two anti-preS2 antibodies tested while preS2 deletion mutants were resistant. By infection experiments using viral particles with lost versus increased M protein expression, or a neutralization escaping preS2 deletion only present on L or M protein, we found that both full-length L and M proteins contributed to virus neutralization by the two anti-preS2 antibodies. Thus, immune escape could be a driving force for the selection of M-minus mutations, and especially preS2 deletions. The fact that both L and M proteins could mediate neutralization by anti-preS2 antibodies may shed light on the underlying molecular mechanism.IMPORTANCEThe large (L), middle (M), and small (S) envelope proteins of hepatitis B virus (HBV) contain preS1/preS2/S, preS2/S, and S domain alone, respectively. The discovery of heparan sulfate proteoglycans and sodium taurocholate cotransporting polypeptide (NTCP) as the low- and high-affinity HBV receptors could explain neutralizing potential of anti-S and anti-preS1 antibodies, respectively, but how anti-preS2 neutralizing antibodies work remains enigmatic. In this study, we found two M-minus mutants in the context of genotype D partially escaped two anti-preS2 neutralizing antibodies in NTCP-reconstituted HepG2 cells, while several naturally occurring preS2 deletion mutants escaped both antibodies. By point mutations to eliminate or enhance M protein expression, and by introducing preS2 deletion selectively to L or M protein, we found binding of anti-preS2 antibodies to both L and M proteins contributed to neutralization of wild-type HBV infectivity. Our finding may shed light on the possible mechanism(s) whereby anti-preS2 antibodies neutralize HBV infectivity.

Hepatitis B Reactivation and Vaccination Effectiveness after Solid Organ Transplantation: A Matched Case-Control Study. Vaccines (Basel) 2024; 12:804. [PMID: 39066442 PMCID: PMC11281428 DOI: 10.3390/vaccines12070804] [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: 06/21/2024] [Revised: 07/13/2024] [Accepted: 07/18/2024] [Indexed: 07/28/2024] Open
Abstract
Solid organ transplant (SOT) recipients are at significant risk of hepatitis B (HB) virus (HBV) reactivation (HBVr). Despite the clinical significance of HBVr after solid organ transplantation, data on the risk factors for HBVr and vaccine effectiveness in SOT recipients with resolved HBV infection are limited. This study evaluated the risk factors for HBVr and the seroconversion rates after HBV vaccination in SOT recipients. Patients who had undergone solid organ transplantation and those with a resolved HBV infection were identified. We matched patients who experienced post-transplantation HBVr with those who did not. We also explored the characteristics and seroconversion rates of HBV-vaccinated patients following transplantation. In total, 1299 SOT recipients were identified as having a resolved HBV infection at the time of transplantation. Thirty-nine patients experienced HBVr. Pre-transplant HB surface antibodies (anti-HBs) positivity and allograft rejection within 3 months after transplantation were independently associated with HBVr. Among the 17 HBV-vaccinated patients, 14 (82.4%) received three or fewer vaccine doses, and 13 (76.5%) had seroconversion with positive anti-HBs results. Pre-transplant anti-HBs(-) status and allograft rejection were risk factors for HBVr in SOT recipients with a resolved HBV infection, and HBV vaccination after transplantation resulted in a high rate of anti-HBs seroconversion. HBV vaccination after transplantation should be considered to reduce the HBVr risk.

Abstract
We have successfully accomplished a catalytic asymmetric total synthesis of entecavir, a first-line antihepatitis B virus medication. The pivotal aspect of our strategy lies in the utilization of a Pd-catalyzed enyne borylative cyclization reaction, enabling the construction of a highly substituted cyclopentene scaffold with exceptional stereoselectivity. Additionally, we efficiently accessed the crucial 1,3-diol enyne system early in our synthetic route through a diarylprolinol organocatalyzed enantioselective cross-aldol reaction and Re-catalyzed allylic alcohol relocation. By strategically integrating these three catalytic protocols, we established a practical pathway for acquiring valuable densely heteroatom-substituted cyclopentene cores.

Abstract
AIM An association between hepatitis B core-related antigen (HBcrAg) kinetics and hepatocarcinogenesis during nucleoside (t)id analog (NA) treatment has recently been reported. HBcrAg kinetics and factors associated with HBcrAg response during tenofovir alafenamide (TAF) administration remain unclear. In this multicenter retrospective study, we aimed to clarify the efficacy and safety of TAF in treatment-naïve patients with chronic hepatitis B, focusing on the reduction in HBcrAg levels. METHODS Patients were treated with TAF monotherapy for 96 weeks, and the kinetics of HBcrAg during treatment and the factors associated with HBcrAg response (defined as a change in HBcrAg of -1 log IU/mL from baseline) were evaluated. RESULTS The study population comprised 241 patients, 36.9% of whom were HBeAg-positive. The median baseline HBcrAg level was 4.7 log IU/mL. The median change in HBcrAg from baseline was -1.1 log IU/mL at 96 weeks after treatment. The HBcrAg response rate at 96 weeks was 56.6% (43/76). Multivariate analysis revealed high alanine transaminase level as an independent baseline factor associated with HBcrAg response at 96 weeks of treatment (p = 4.53 × 10-6). No correlation was found between the HBcrAg and hepatitis B surface antigen kinetics in patients treated with TAF monotherapy. CONCLUSIONS In TAF monotherapy for patients with chronic hepatitis B, HBcrAg levels were significantly decreased and baseline alanine transaminase level is an important factor associated with HBcrAg reduction. As no correlation was found between HBcrAg and reduced hepatitis B surface antigen levels in this study, HBcrAg kinetics in addition to hepatitis B surface antigen may need to be monitored during TAF treatment.

Abstract
Background Hepatotoxicity is the foremost issue for clinicians and the primary reason for pharmaceutical product recalls. A biomarker is a measurable and quantifiable attribute used to evaluate the efficacy of a treatment or to diagnose a disease. There are various biomarkers which are used for the detection of liver disease and the intent of liver damage. Objective This review aims to investigate the current state of hepatotoxicity biomarkers and their utility in clinical settings. Using hepatic biomarkers, the presence of liver injury, its severity, prognosis, causative agent, and type of hepatotoxicity can all be determined. Methods Relevant published articles up to 2022 were systematically retrieved from MEDLINE/PubMed, SCOPUS, EMBASE, and WOS databases using keywords such as drug toxicity, hepatotoxicity biomarkers, biochemical parameters, and nonalcoholic fatty liver disease. Results In clinical trials and everyday practice, biomarkers of drug-induced liver injury are essential for spotting the most severe cases of hepatotoxicity. Hence, developing novel biomarker approaches to enhance hepatotoxicity diagnosis will increase specificity and/or identify the person at risk. Importantly, early clinical studies on patients with liver illness have proved that some biomarkers such as aminotransferase, bilirubin, albumin, and bile acids are even therapeutically beneficial. Conclusions By assessing the unique signs of liver injury, health care professionals can rapidly and accurately detect liver damage and evaluate its severity. These measures contribute to ensuring prompt and effective medical intervention, hence reducing the risk of long-term liver damage and other major health concerns.

Abstract
BACKGROUND AND AIMS This study aimed to compare the efficacy of shorter vs. longer tenofovir disoproxil fumarate (TDF) prophylaxis in preventing hepatitis B virus (HBV) relapse in cancer patients with chronic hepatitis B (CHB) undergoing chemotherapy. METHODS This phase IV, prospective randomized trial enrolled cancer patients with CHB from 2014 to 2019 in Taiwan. Included patients were randomized to receive either 24- (Arm A) or 48-week (Arm B) post-chemotherapy TDF and compared for cumulative incidence of virological and clinical relapse. Logistic regressions were conducted to determine the factors associated with HBV relapse. RESULTS One hundred patients were randomized, and 41 patients in Arm A and 46 in Arm B completed the TDF treatment. No significant difference was found in cumulative incidence of virological relapse (Arm A: 94.4%, Arm B: 93.1%, p = 0.110) or clinical relapse among patients with baseline HBV DNA > 2000 IU/mL (Arm A: 38.9%, Arm B: 26.7%, p = 0.420) between the two arms. High baseline HBV DNA ≥ 10,000 IU/mL (OR = 51.22) and HBsAg ≥ 1000 IU/mL (OR = 8.64) were independently associated with an increased virological relapse. Alanine aminotransferase (ALT), serum phosphorus, vitamin D, and estimated glomerular filtration rate (eGFR) remained stable throughout the study. CONCLUSIONS The 24-week preventative TDF has comparable efficacy to the 48-week treatment in virologic and clinical relapse. High baseline HBsAg or HBV DNA is associated with a higher risk of HBV relapse. These findings imply a 24-week duration of TDF treatment with a close monitor for patients with a high baseline viral load. Hepatitis B virus infection is a prominent cause of liver cancer and chronic liver disease and affected millions of people worldwide. When HBV-infected people are exposed to immunosuppressive medication or chemotherapy for cancer, the chance of HBV reactivation rises considerably. This trial showed 24-week tenofovir disoproxil fumarate (TDF) may be sufficient for preventing HBV relapse in cancer patients receiving chemotherapy. CLINICAL TRIAL REGISTRATION NUMBER NCT02081469.

Abstract
Liver-specific ten-eleven translocation (Tet) methylcytosine dioxygenases 2 and 3 (Tet2 plus Tet3)-deficient hepatitis B virus (HBV) transgenic mice fail to support viral biosynthesis. The levels of viral transcription and replication intermediates are dramatically reduced. Hepatitis B core antigen is only observed in a very limited number of pericentral hepatocytes in a pattern that is similar to glutamate-ammonia ligase (Glul), a β-catenin target gene. HBV transcript abundance in adult Tet-deficient mice resembles that observed in wild-type neonatal mice. Furthermore, the RNA levels of several β-catenin target genes including Glul, Lhpp, Notun, Oat, Slc1a2, and Tbx3 in Tet-deficient mice were also similar to that observed in wild-type neonatal mice. As HBV transcription is regulated by β-catenin, these findings support the suggestion that neonatal Tet deficiency might limit β-catenin target gene expression, limiting viral biosynthesis. Additionally, HBV transgene DNA displays increased 5-methylcytosine (5mC) frequency at CpG sequences consistent with neonatal Tet deficiency being responsible for decreased developmental viral DNA demethylation mediated by 5mC oxidation to 5-hydroxymethylcytosine, a process that might be responsible for the reduction in cellular β-catenin target gene expression and viral transcription and replication.IMPORTANCEChronic hepatitis B virus (HBV) infection causes significant worldwide morbidity and mortality. There are no curative therapies available to resolve chronic HBV infections, and the small viral genome limits molecular targets for drug development. An alternative approach to drug development is to target cellular genes essential for HBV biosynthesis. In the liver, ten-eleven translocation (Tet) genes encode cellular enzymes that are not essential for postnatal mouse development but represent essential activities for viral DNA demethylation and transcription. Consequently, Tet inhibitors may potentially be developed into therapeutic agents capable of inducing and/or maintaining HBV covalently closed circular DNA methylation, resulting in transcriptional silencing and the resolution of chronic viral infection.

Rapid hepatitis B (HB) surface antibody (anti-HBs) loss is prevalent after liver transplantation (LT). Herein, we evaluated anti-HBs persistence after HB vaccination using two regimens in LT children. We recruited 66 previously immunized LT children with anti-HBs level of < 100 mIU/mL. Participants were randomly reimmunized with standard-three-dose (SD) and double-three-dose (DD) intramuscular HB vaccination at 0, 1, and 6 months. Anti-HBs were assessed at every outpatient visit. Antibody loss defined as anti-HBs levels < 100 mIU/mL after three-dose vaccination. After three-dose vaccination, 81.8% and 78.7% of participants in the SD and DD groups, had anti-HBs levels > 100 mIU/mL, with a geometric mean titer (GMT) of 601.68 and 668.01 mIU/mL (P = 0.983). After a mean follow-up of 2.31 years, the anti-HBs GMT was 209.81 and 212.61 mIU/mL in the SD and DD groups (P = 0.969). The number of immunosuppressants used and an anti-HBs level < 1 mIU/mL at baseline were independently associated with anti-HB loss. The DD regimen strongly increased the risk of anti-HBs loss (adjusted hazard ratio, 2.97 [1.21-7.31]; P = 0.018). The SD HB reimmunization regimen effectively maintained protective anti-HBs levels in children undergoing LT, making it the preferred regimen for such children with anti-HB loss.Trial registration: TCTR20180723002.

CLINICAL PATHOLOGY (THOUSAND OAKS, VENTURA COUNTY, CALIF.) 2024; 17:2632010X241265858. [PMID: 39139860 PMCID: PMC11320404 DOI: 10.1177/2632010x241265858] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Accepted: 06/11/2024] [Indexed: 08/15/2024]
Abstract
Background Patients with acute-on-chronic liver failure (ACLF) who take entecavir (ETV) and tenofovir disoproxil fumarate (TDF) experience a reduction in hepatic events and mortality. The effectiveness of tenofovir alafenamide (TAF) was not well investigated. This study was aim to compare the antiviral efficacy and mortality between TAF and ETV in patients with ACLF caused by the hepatitis B virus (HBV). Methods One hundred and six patients with HBV-ACLF who received TAF (25 mg/day) and ETV (0.5 mg/day) for 12 weeks were analyzed. The primary endpoints were overall mortality and liver transplantation (LT) at week 12. Biochemical responses, virologic responses, mortality, drug safety, and side effects were evaluated. Results At 4 and 12 weeks of TAF treatment, patients showed significantly higher HBV-DNA reduction (P < .001), higher HBV-DNA undetectability rates (P < .001), and lower HBV DNA levels (P < .001) in serum. Lower Child-Turcotte-Pugh (CTP) scores (P = .003) were observed at 4 weeks in the TAF group, although the CTP scores showed no difference between TAF group and ETV group at 12 weeks (P = 1.143). Lower alanine aminotransferase (ALT) levels of patients in the TAF group at week 4 and 12 were observed (P = .023 and P < .0001, separately). The mortality of TAF group was lower after 4 weeks of treatment (P = .038); however, the 2 groups had similar mortality rates at week 8 and 12. Among the causes of death in HBV-ACLF patients, we found the same incidence of liver-related problems in both groups (P > .05). Conclusions This study showed that ACLF patients with chronic HBV infection treated with TAF had a rapid decline in HBV DNA, a higher rate of ALT reduction and improved CTP scores compared to the ETV group, thereby improving patient survival.

Abstract
Background The molecule known as Interleukin-8 (IL-8), a chemotactic leukocyte, has been found to have a crucial role in the perpetuation of the inflammatory environment that is associated with hepatitis B virus (HBV) infection, as well as in the development of liver cirrhosis and cancer. Objective The aim of this study was to carefully examine the role of IL-8 in the inflammatory reaction and to compare the levels based on the severity of liver cirrhosis. Methods The study was conducted from February 2018 to September 2018 at the Gastroenterohepatology Division, Internal medicine Department, Faculty of Medicine, Universitas Sumatera Utara. The study was designed as an analytic comparative, cross-sectional study. The liver cirrhosis patients who participated in this study met the inclusion criteria and provided informed consent. Results A total of 70 patients were included in the study, from which we identified 1 individual with child-pugh A, 28 individuals with child-pugh B, and 41 individuals with child-pugh C. The serum level of IL-8 was found to be 98 (11-320) (pg/ml). The IL-8 levels between child-pugh B and C patients did not exhibit any noteworthy differences during our analysis (p = 0.109, p>0.05). Conclusion There is no notable inequality in the levels of IL-8 across different stages of liver cirrhosis.

Abstract
Patients with chronic hepatitis B (CHB) are regularly monitored for HBV DNA and liver enzymes in order to assess disease progression and the need for antiviral therapy. Identifying patients with a stable course of disease can potentially prolong the intervals between visits, withhold unnecessary tests and save money. Accordingly, we aimed to find predictors for a stable disease course in patients with CHB. 579 patients with CHB, who were followed in a tertiary referral center between January 2004-December 2018, were retrospectively analyzed. Patients with low and steady viral load titer (< 2000 IU/ml) and normal ALT levels (< 40 IU/ml) in 6 consecutive clinic encounters were considered to have a stable course of CHB. A stepwise multivariate logistic regression analysis and a decision tree model were used to identify predictors of a stable disease course. Following exclusion of ineligible patients, a total of 220 patients were included in the final analysis. 64/220 patients had a stable disease course. Patients with a stable disease were older (62.99 ± 12.36 Vs. 54.07 ± 13.64, p < 0.001) with a higher percentage of women (53% vs. 38%) and had lower baseline levels of AST, ALT and viral load (VL). In a multivariate analysis, age (OR 0.94, 95% CI 0.91-0.98), baseline ALT (OR 1.06, 95% CI 1.01-1.1) and VL (OR 1.05 95% CI 1.02-1.08), were significantly associated with a stable disease. In a decision tree model, patients 46-67 years old, with baseline VL < 149 IU/mL and ALT < 40 IU/mL had the best probability (91%) for a stable disease course over 4.4 ± 2.2 years. We conclude that integrating patients' age with baseline VL and ALT can predict a stable disease course in patients with CHB off treatment.

Abstract
Introduction: The effective and persistent suppression of hepatitis B surface antigen (HBsAg) in patients with chronic HBV infection (CHB) is considered to be a promising approach to achieve a functional cure of hepatitis B. In our previous study, we found that the antibody E6F6 can clear HBsAg through FcγR-mediated phagocytosis, and its humanized form (huE6F6 antibody) is expected to be a new tool for the treatment of CHB. Previous studies have shown that the glycosylation of Fc segments affects the binding of antibodies to FcγR and thus affects the biological activity of antibodies in vivo. Methods: To further improve the therapeutic potential of huE6F6, in this study, we defucosylated huE6F6 (huE6F6-fuc-), preliminarily explored the developability of this molecule, and studied the therapeutic potential of this molecule and its underlying mechanism in vitro and in vivo models. Results: huE6F6-fuc- has desirable physicochemical properties. Compared with huE6F6-wt, huE6F6-fuc- administration resulted in a stronger viral clearance in vivo. Meanwhile, huE6F6-fuc- keep a similar neutralization activity and binding activity to huE6F6-wt in vitro. Immunological analyses suggested that huE6F6-fuc- exhibited enhanced binding to hCD32b and hCD16b, which mainly contributed to its enhanced therapeutic activity in vivo. Conclusions: In summary, the huE6F6-fuc- molecule that was developed in this study, which has desirable developability, can clear HBsAg more efficiently in vivo, providing a promising treatment for CHB patients. Our study provides new guidance for antibody engineering in other disease fields.

Abstract
Background and Aims A functional cure, or hepatitis B virus (HBV) surface antigen (HBsAg) loss, is difficult to achieve in patients with hepatitis B virus e antigen (HBeAg)-positive chronic hepatitis B. The HBV vaccine and granulocyte-macrophage colony-stimulating factor (GM-CSF) have been reported to help reduce HBsAg levels and promote HBsAg loss. In this prospective randomized trial, we evaluated HBsAg loss in patients receiving pegylated interferon-α2b (PEGIFN-α2b) and tenofovir disoproxil fumarate (TDF), with and without GM-CSF and HBV vaccination. Methods A total of 287 patients with HBeAg positive chronic hepatitis B and seroconversion after nucleot(s)ide analog treatment were assigned randomly to three treatment groups for 48 weeks, TDF alone (control), PEGIFN-α2b + TDF, and PEGIFN-α2b + TDF + GM-CSF + HBV vaccine. The primary endpoints were the proportions of patients with HBsAg loss and seroconversion at 48 and 72 weeks. Results The cumulative HBsAg loss rates in the control, PEGIFN-α2b + TDF, and PEGIFN-α2b + TDF + GM-CSF + HBV vaccine groups at week 48 were 0.0%, 28.3%, and 41.1%, respectively. The cumulative HBsAg seroconversion rates in these groups at week 48 were 0.0%, 21.7%, and 33.9%, respectively. Multivariate regression analysis showed that GM-CSF use plus HBV vaccination was significantly associated with HBsAg loss (p=0.017) and seroconversion (p=0.030). Conclusions In patients with HBeAg-positive chronic hepatitis B and seroconversion after nucleot(s)ide analog treatment, immunomodulatory/antiviral treatment regimens effectively improved HBsAg loss, and the regimen including GM-CSF and HBV vaccination was most effective.

Abstract
Introduction Chronic hepatitis B (CHB) continues to be a significant global public health problem. Conventional serological markers play a pivotal role in diagnosing and prognosticating CHB, but atypical serological profiles deviating from established norms pose challenges. Methods A cohort of 35 CHB patients who did not receive an antiviral treatment with atypical serological markers was followed for five years (2017-2022). Demographics, serological parameters, and changes were documented. Serological parameters and serum viral loads (hepatitis B virus (HBV)-deoxyribonucleic acid (DNA) levels) were assayed at the central laboratory during their routine follow-ups. Three groups of atypical serological markers are defined: hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) positivity; hepatitis B e antigen (HBeAg) and anti-hepatitis B e-antigen (anti-HBe) positivity; and isolated core (anti-hepatitis B core (anti-HBc) immunoglobulin G (IgG)) positivity. Patients with concomitant HBsAg and anti-HBs were also stratified into seroreversion groups. Changes in serological markers and HBV-DNA levels across the study period were documented and evaluated at the end of the study period. Statistical analysis was conducted using the Kruskal-Wallis test and IBM SPSS Statistics software for Windows, Version 23.0 (IBM Corp., Armonk, NY, USA). Results In a cohort of 35 patients with atypical hepatitis B serology, demographic analysis revealed that 51.4% (n=18) were female and 48.6% (n=17) were male, with a mean age of 45.7 years. Educational distribution showed that 45.7% (n=16) completed primary education, 22.8% (n=8) had a high school education, and 31.5% (n=11) held university degrees. Among these patients, 10 displayed the concurrent presence of HBsAg and anti-HBs, with 60% (n=6) being female. Serum HBV-DNA was detectable in all cases. After five years, 60% (n=6) exhibited seroconversion from HBsAg to anti-HBs, particularly notable in females (66.7%). These patients showed lower HBsAg titers and serum HBV-DNA levels (p = 0.048, p = 0.036). A subset of 15 patients demonstrated simultaneous HBeAg and anti-HBe positivity. The HBeAg seropositivity waned over time, with 40% (n=6) and 26.7% (n=4) females and males, respectively, retaining positivity by the fifth year. During this period, serum HBV-DNA levels decreased. The remaining five patients sustained HBeAg and anti-HBe positivity. Among 10 patients solely positive for anti-HBc IgG, three had concurrent HBV-DNA positivity. Strikingly, three patients with negative HBV-DNA developed anti-HBs positivity after five years. Conclusion The complexity of CHB infection demands a comprehensive understanding. Atypical serological profiles suggest distinct disease stages, immune response variations, and viral mutations. This study enhances comprehension of viral replication, immune responses, and disease progression, potentially guiding tailored therapeutic strategies.

[PMID: 36317514 PMCID: PMC10018308 DOI: 10.5009/gnl220122] [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: 03/24/2022] [Revised: 06/02/2022] [Accepted: 06/21/2022] [Indexed: 11/07/2022] Open
Abstract
Background/Aims Hepatitis B surface antigen (HBsAg) seroclearance remains uncommon in chronic hepatitis B (CHB) infection. During acute flares of CHB (AFOCHB), alanine aminotransferase elevation reflects a mounting immune response toward viral clearance. We hypothesized that severe AFOCHB is associated with a greater quantitative HBsAg (qHBsAg) decline and HBsAg seroclearance rate. Methods A total of 75 patients with severe AFOCHB with alanine aminotransferase 10× the upper limit of normal were matched to a control group by age and sex in a 1:2 ratio. qHBsAg levels were measured at the time of flare and annually (for both cases and controls) until the last follow-up. Results The median follow-up times for patients with severe AFOCHB and controls were 8.8 and 10.5 years, respectively. The cumulative rate of HBsAg seroclearance was higher in the severe AFOCHB group than in the control group (11.8% vs 5.0%, p=0.04) despite the former group having a trend of a higher baseline median qHBsAg (3,127 IU/mL vs 1,178 IU/mL, p=0.076). Compared with the control group, the severe AFOCHB group had a greater annual qHBsAg reduction (-242.4 IU/mL/yr vs -47.3 IU/mL/yr, p=0.002). Increasing age (p=0.049), lower baseline qHBsAg (p=0.002), and severe AFOCHB (p=0.014) were independently associated with HBsAg seroclearance. However, the cumulative rate of hepatocellular carcinoma was significantly higher in the severe AFOCHB group than in the control group (15.8% vs 1.9%, p<0.001). Conclusions Severe AFOCHB was associated with a greater incidence of HBsAg seroclearance and qHBsAg decline. However, it was associated with a higher incidence of hepatocellular carcinoma.

Abstract
Acute liver injury in the setting of acute fulminant hepatitis caused by the hepatitis B virus (HBV) can occur both during primary infection and after chronic HBV reactivation. Guidelines recommend considering antiviral therapy in both cases. Antiviral therapy with a nucleoside analog may be beneficial in patients with acute liver failure from acute HBV infection, though not all studies have shown a benefit. This is a case of a 53-year-old woman with a past medical history of untreated hepatitis C with undetectable viral load and right breast cancer status post lumpectomy, who presented to the emergency department with complaints of yellowish skin and sclera discoloration with right upper quadrant pain for one week. She was a known intravenous drug abuser and binge alcohol user. Her labs were positive for hepatitis B, hepatitis E, and hepatitis C viruses. She also had elevated liver enzymes with hyperbilirubinemia showing severe acute liver injury. Computed tomography of the abdomen and pelvis with contrast was normal, and the abdominal ultrasound showed homogenous echotexture of the liver without a focal lesion. The patient was diagnosed with acute fulminant hepatitis B. After initial hemodynamic stabilization, N-acetylcysteine (NAC) and tenofovir were started, and transaminases were followed. Liver function tests showed a downtrend, and, in a few weeks, they came to baseline. Hepatitis B viral load became undetectable as well. Acute hepatitis B infection is seldom treated. The presented case depicts the use of tenofovir in the setting of severe acute liver injury due to hepatitis B. Starting antiviral therapy (especially tenofovir disoproxil fumarate) early in the disease course was shown to have very assuring results with complete resolution of symptoms and normalization of liver function tests. The treatment protocol for acute HBV deserves further investigation.

Abstract
Chronic hepatitis B (CHB) is a major public health problem in the world. It is the main cause of liver cirrhosis and liver cancer. Although many important roles of RNA modification in stem cells or tumor diseases have been identified, the role of N7-methylguanosine (m7G) modification in the process of chronic HBV infection has not been clearly defined. Therefore, we conducted a systematic analysis on the process of chronic HBV infection. We found that a total of 18 m7G-related genes were altered in chronic HBV infection, and then we screened out CHB potential diagnostic biomarkers using machine learning and random forest methods. RT-qPCR was performed on the samples of healthy people and CHB, which further verified the possibility of being a diagnostic marker. Then, we typed CHB patients based on these 18 genes. We found that the immune microenvironment of different subtypes was different. Among them, patients with subtype-Ⅰ had severe immune response, that is, relatively serious immune cell infiltration, rich immune pathways, relatively many HLA genes, and immune checkpoints. Finally, we conducted an in-depth discussion on our m7G-related genes, and found that m7G gene related to immune cell infiltration may be involved in the disease progression of CHB patients, which was also confirmed in the GSE84044 dataset. In conclusion, m7G-related genes can not only serve as diagnostic markers of CHB, but also participate in the regulation of immune microenvironment and play an important role in the progression of CHB.

Abstract
Myeloid derived suppressor cells (MDSCs) are a heterogenous population of myeloid cells derived from monocyte and granulocyte precursors. They are pathologically expanded in conditions of ongoing inflammation where they function to suppress both innate and adaptive immunity. They are subdivided into three distinct subsets: monocytic (M-) MDSC, polymorphonuclear (or neutrophilic) (PMN-) MDSC and early-stage (e-) MDSC that may exhibit differential function in different pathological scenarios. However, in cancer they are associated with inhibition of the anti-tumour immune response and are universally associated with a poor prognosis. Seven human viruses classified as Group I carcinogenic agents are jointly responsible for nearly one fifth of all human cancers. These viruses represent a large diversity of species, including DNA, RNA and retroviridae. They include the human gammaherpesviruses (Epstein Barr virus (EBV) and Kaposi's Sarcoma-Associated Herpesvirus (KSHV), members of the high-risk human papillomaviruses (HPVs), hepatitis B and C (HBV, HCV), Human T cell leukaemia virus (HTLV-1) and Merkel cell polyomavirus (MCPyV). Each of these viruses encode an array of different oncogenes that perturb numerous cellular pathways that ultimately, over time, lead to cancer. A prerequisite for oncogenesis is therefore establishment of chronic infection whereby the virus persists in the host cells without being eradicated by the antiviral immune response. Although some of the viruses can directly modulate the immune response to enable persistence, a growing body of evidence suggests the immune microenvironment is modulated by expansions of MDSCs, driven by viral persistence and oncogenesis. It is likely these MDSCs play a role in loss of immune recognition and function and it is therefore essential to understand their phenotype and function, particularly given the increasing importance of immunotherapy in the modern arsenal of anti-cancer therapies. This review will discuss the role of MDSCs in viral oncogenesis. In particular we will focus upon the mechanisms thought to drive the MDSC expansions, the subsets expanded and their impact upon the immune microenvironment. Importantly we will explore how MDSCs may modulate current immunotherapies and their impact upon the success of future immune-based therapies.

The Impact of b/tsDMARD Dose Reduction on Chronic Hepatitis B in Rheumatoid Arthritis Patients: A Two-Center Long-Term Safety Analysis. J Clin Med 2022; 12:jcm12010086.

Abstract
BACKGROUND We aimed to investigate the change of hepatitis B virus (HBV) viral loads and HBV reactivation (HBVr) in rheumatoid arthritis (RA) patients after tapering the dose of biological/targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs). METHODS This two-center analysis retrospectively investigated the virological and biochemical evidence of HBVr in RA patients who underwent b/tsDMARD dose reduction. Serum levels of viral loads were determined using real-time PCR. Serum levels of alanine transaminase (ALT) were determined using spectrophotometry. RESULTS Among a total of 40 HBsAg+ RA patients who tapered b/tsDMARDs, 14 (35%) used tocilizumab; 12 (30%) used tumor necrosis factor (TNF)-α inhibitors; and the rest used either abatacept or tofacitinib. We found that patients who had detectable HBV DNA before tapering achieved a one-log reduction in HBV DNA levels, in contrast to the findings in the other 12 patients who did not taper b/tsDMARDs (no change in HBV DNA levels with time). The incidence of HBVr (increased viral loads with hepatitis) was 4.62 (95%CI: 2.08, 10.28) and 2.26 (95%CI: 0.56, 9.02) events per 100 person-years before and after b/tsDMARD tapering, respectively. CONCLUSIONS The HBV viral load decreased after the tapering of b/tsDMARDs in RA patients with detectable HBV DNA. Dose reduction in b/tsDMARDs might be beneficial.

Abstract
With the recent availability and upgrading of many emerging intestinal microbes sequencing technologies, our research on intestinal microbes is changing rapidly. A variety of investigations have found that intestinal microbes are essential for immune system regulation and energy metabolism homeostasis, which impacts many critical organs. The liver is the first organ to be traversed by the intestinal portal vein, and there is a strong bidirectional link between the liver and intestine. Many intestinal factors, such as intestinal microbes, bacterial composition, and intestinal bacterial metabolites, are deeply involved in liver homeostasis. Intestinal microbial dysbiosis and increased intestinal permeability are associated with the pathogenesis of many chronic liver diseases, such as alcoholic fatty liver disease (AFLD), non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), chronic hepatitis B (CHB), chronic hepatitis C (CHC), autoimmune liver disease (AIH) and the development of hepatocellular carcinoma (HCC). Intestinal permeability and dysbacteriosis often lead to Lipopolysaccharide (LPS) and metabolites entering in serum. Then, Toll-like receptors activation in the liver induces the exposure of the intestine and liver to many small molecules with pro-inflammatory properties. And all of these eventually result in various liver diseases. In this paper, we have discussed the current evidence on the role of various intestinal microbes in different chronic liver diseases. As well as potential new therapeutic approaches are proposed in this review, such as antibiotics, probiotics, and prebiotics, which may have an improvement in liver diseases.

Abstract
Nuclear located hepatitis B virus (HBV) covalently closed circular DNA (cccDNA) remains the key obstacle to cure chronic hepatitis B (CHB). In our previous investigation, it was found that FoxO4 could inhibit HBV core promoter activity through downregulating the expression of HNF4α. However, the exact mechanisms whereby FoxO4 inhibits HBV replication, especially its effect on cccDNA, remain unclear. Here, our data further revealed that FoxO4 could effectively inhibit cccDNA mediated transcription and HBV replication without affecting cccDNA level. Mechanistic study showed that FoxO4 could cause epigenetic suppression of cccDNA. Although FoxO4-mediated downregulation of HNF4α contributed to inhibiting HBV core promoter activity, it had little effect on cccDNA epigenetic regulation. Further, it was found that FoxO4 could colocalize within promyelocytic leukemia protein (PML) nuclear bodies and interact with PML. Of note, PML was revealed to be critical for FoxO4-mediated inhibition of cccDNA epigenetic modification and of the following cccDNA transcription and HBV replication. Furthermore, FoxO4 was found to be downregulated in HBV-infected hepatocytes and human liver tissues, and it was negatively correlated with cccDNA transcriptional activity in CHB patients. Together, these findings highlight the role of FoxO4 in suppressing cccDNA transcription and HBV replication via genetic downregulation of HNF4α and epigenetic suppression of cccDNA through interacting with PML. Targeting FoxO4 may present as a new therapeutic strategy against chronic HBV infection. IMPORTANCE HBV cccDNA is a determining factor for viral persistence and the main obstacle for a cure of chronic hepatitis B. Strategies that target cccDNA directly are therefore of great importance in controlling persistent HBV infection. In present investigation, we found that FoxO4 could efficiently suppress cccDNA transcription and HBV replication without affecting the level of cccDNA itself. Further, our data revealed that FoxO4 might inhibit cccDNA function via a two-part mechanism: one is to epigenetically suppress cccDNA transcription via interacting with PML, and the other is to inhibit HBV core promoter activity via the genetic downregulation of HNF4α. Of note, HBV might dampen the expression of FoxO4 for its own persistent infection. We propose that manipulation of FoxO4 may present as a potential therapeutic strategy against chronic HBV infection.

Abstract
BACKGROUND AND AIMS Hepatitis B virus (HBV) is a common viral pathogen that infects more than a third of the world's population; however, the transmission route remains to be further defined. The 18-year implementation of free HBV vaccine for children has greatly changed the prevalence of HBV infection in China, which presents a unique real-world model for assessing the pattern of HBV transmission. METHODS Cross-sectional data of HBV seromarkers between July 2019 and April 2020 were collected from 53,371 individuals aged 1-60 years in four areas of North to South in Eastern China. Longitudinal data of HBV seromarkers between 2007 and 2020 were collected from 177 adults in an area of South China. The regional- and age-specific changes in HBV seromarkers were analyzed. RESULTS Overall, positive rates of HBV surface antigen (HBsAg) (from 3.44% to 15.1%) and antibody against HBV core antigen (anti-HBc) (from 7.6% to 44.0%) significantly increased from North to South. Among persons aged ≤18 years, the positive rates of antibody against HBsAg (anti-HBs) and anti-HBc (+) remained at low levels in the North, while they were increasing among persons aged >12 years in the South, despite higher positive rates of anti-HBs (+). Among persons aged >18 years, the anti-HBs (+) rates remained relatively stable (~60%), while anti-HBc (+) rates increased significantly with age. Up to ~80% of the anti-HBs (+) adults in the South was anti-HBc (+) while it was 13.6% in the North. In the longitudinal cohort, the anti-HBc (+) rate among adults in the South increased by 14.2% during 10 years of follow-up. CONCLUSION Horizontal transmission might be a common route in highly endemic areas, and may help to explain the high HBV exposure worldwide. The risk of horizontal transmission among children without seroprotective anti-HBs should be notified in highly endemic areas. This article is protected by copyright. All rights reserved.

Abstract
Hepatic malignancies remain a global challenge. Hepatocellular carcinoma (HCC) accounts for around 90% of patients with liver cancer and is the sixth most common neoplasm worldwide and the fourth leading cause of cancer-related death. However, the long-term prognosis for HCC remains far from satisfactory, with a late diagnosis and limited treatment. DOX has served as conventional chemotherapy with the longest history of use. Although conventional chemotherapy is being challenged by molecular therapy and immune therapy, there is renewed optimism and interest in both systematic and locoregional therapy. Combined chemotherapy is widely used in clinical practice. In specific terms, FOLFOX can serve as a first-line (category 2B) option as recommended by the 2021 NCCN guidelines, while the efficacy of LTLD plus RFA has been confirmed in the phase III HEAT study. These approaches have challenged the dominant status of molecular therapy in terms of health economics and they have potential benefits in Asia, where HBV-related hepatocellular carcinoma is prevalent. Moreover, locoregional chemotherapy can be achieved with TACE and HAIC (possibly involving FOLFOX, DOX, mitomycin C, cisplatin, epirubicin, etc.). TACE was officially recommended by the 2021 NCCN guidelines for patients with Child-Pugh class B liver disease. In addition, HAIC has demonstrated a potential advantage in preliminary clinical practice, although it hasn't been included in any guidelines. Hence, this review summarizes large-scale trials and studies examining the development and innovative use of chemotherapeutic agents. Mounting clinical evidence warrants an exploration of the efficacy of chemotherapy.

Abstract
Formula Le-Cao-Shi (LCS), a traditional Chinese medicine (TCM), has been used as folk remedy for treating hepatitis B for a long time. In our previous study, the anti-hepatitis B effects of LCS have been verified. In the present study, the anti-hepatitis B activities of LCS and its three single herbs were investigated in vitro by HepG2.2.15 cellular model, and the mechanisms against hepatitis B were deciphered via network pharmacology and gut microbiota analysis. By network pharmacology method, twelve key compounds that played a vital role in LCS were filtered from 213 ingredients. The targets RORA, CDK2, RELA, AKT1, IKBKG, PRKCβ and CASP3 were directly related to hepatitis B pathway, which indicated that LCS could exert anti-hepatitis B effect by co-regulating cell cycle and inflammatory pathways. The interactions between candidate compounds and target proteins that were directly involved in hepatitis B pathway were validated by molecular docking simulation and RT-PCR. By gut microbiota analysis, it was revealed that LCS could alter the disordered microbial composition in the infected ducks towards normal, especially the restoration of three key strains, namely Streptococcus alactolyticus, Enterococcus cecorum and Bacteroides fragilis. The above findings could provide a scientific basis for further development and utilization of LCS against hepatitis B.

INFECTIOUS DISEASES: RESEARCH AND TREATMENT 2022; 15:11786337211062622. [PMID: 35023926 PMCID: PMC8744165 DOI: 10.1177/11786337211062622] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/11/2021] [Accepted: 11/08/2021] [Indexed: 11/17/2022]
Abstract
Background: Healthcare providers are in high occupational risk of Hepatitis B virus
infection than that of the general population because of the high risk of
occupational exposure to patients’ body fluids and accidental sharp
injuries. There are no large facility-based studies conducted on the
prevalence of HBV infection and its associated factors among health care
providers in eastern Ethiopia. Objective: This study aimed at investigating the seroprevalence of Hepatitis B Virus and
its associated factors among the healthcare providers in public health
facilities in eastern Ethiopia. Methods: A facility-based cross-sectional study was conducted among 438 randomly
selected healthcare providers in eastern Ethiopia from March to June 2018.
Pretested structured questionnaire was used to collect data on
socio-demographic characteristics and other risk factors. In addition, a
2.5 ml blood was collected and the serum was analyzed for Hepatitis B
surface antigen using the Instant Hepatitis B surface antigen kit. Data were
entered using Epidata version 3.1 and analyzed using SPSS statistical
packages version 22. Descriptive summary measures were used. Bivariate and
multivariable logistic regression was conducted at 95% CI. An association at
P-value <.05 was considered statistically
significant. Results: A total of 438 (92.02% response rate) health care providers have participated
in this study. The prevalence of hepatitis B virus infection was 9.6%. There
were no significant differences in the HBV infection rates among healthcare
providers with respect to socio-demographic characteristics
(P-value >.05). After adjusting for some variables,
the following variables remained statistically significantly associated with
HBsAg positive result in the multivariable analysis: exposure to body fluids
(AOR = 3.0; 95% CI [1.25, 7.05]), history of needle stick injury
(AOR = 4.70; 95% CI [2.10, 10.55]), history of operation/surgery
(AOR = 4.88, 95% CI [1.43, 16.62]), history of multiple sexual partner
(AOR = 7.48; 95% CI [2.08, 26.96]), and being unvaccinated (AOR = 6.09; 95%
CI [2.75, 13.51]). Conclusion: This study showed a high prevalence of HBV infection among health care
providers in eastern Ethiopia. This is significant because health
professionals may be at increased risk of chronic complications and may also
be source of infection for their clients and general population during their
healthcare practice. Management commitment that should focus on occupational
safety and health promotions is necessary.

[PMID: 34921578 DOI: 10.1111/dth.15274] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Accepted: 12/10/2021] [Indexed: 12/22/2022]
Abstract
Biological therapies used in psoriasis treatment pose a risk of reactivation of hepatitis B virus (HBV) infection. This risk occurs not only in patients with HB surface antigen (HBsAg) (+) but also in patients with past or occult HBV infection (with negative HBsAg, positive HB core antibodies (HBcAb), and positive HBV deoxyribonucleic acid [DNA]). Ustekinumab (UST) is a biologic agent acts by blocking the IL-12/23 pathway. Thus, hindering this response may lead to HBV reactivation. UST therapy is associated with mild HBV-r risk; however, there is insufficient data to confirm that hypothesis. Herein, we present observations on the safety of UST therapy in patients with psoriasis and serologically proved past HBV infection. One-hundred and six consecutive patients with moderate to severe psoriasis treated with biological therapy between May 2013 and January 2020 were retrospectively analyzed. Out of 106 patients, there were five who reported having past HBV. Those five patients were tested for the presence of HBsAg, HBcAb, HBsAb as well as HBV DNA at baseline and at the end of the follow-up period. HBV reactivation was defined as changing of "undetectable" to "detectable" viremia. All five patients were treated with UST. Five patients in our cohort group were found to have resolved HBV infection: HBsAg (-), HBcAb (+), and HBV DNA (-); 4/5 were HBsAb (+) and 1/5 HBsAb (-). None of the patients experienced an increase in their liver function tests values and no signs of hepatitis or HBV reactivation were observed at any point during the study. All the patients were HBsAg and HBV DNA negative at the end of the follow-up period. The average treatment time was 82.4 (28, 96) weeks. The average follow-up time was 75.2 (31, 176) weeks. Based on the available literature and the results from our observations, UST therapy seems to be a safe option for patients with resolved HBV infection.

Abstract
This study aimed to investigate the impact of hepatitis B virus (HBV) infection on the outcome of patients with advanced solid malignancies treated with programmed death receptor-1 (PD-1) inhibitors.We retrospectively included patients treated with PD-1 inhibitors between August 2018 and April 2020. Propensity score matching (PSM) was performed to match the characteristics of the HBV and non-HBV groups. Objective response rate (ORR) and disease control rate (DCR) were compared between HBV and non-HBV groups using χ2 or Fisher exact tests. Kaplan-Meier and log-rank tests were used to analyze overall survival (OS) and progression-free survival (PFS).A total of 120 patients, including 43 (35.8%) with HBV and 77 (64.2%) without HBV, were enrolled. Cases of HBV reactivation were not observed. In the entire study population, ORR and DCR did not significantly differ between both groups. After PSM, the study population comprised 39 patients, 15 with and 24 without HBV. The HBV group had an ORR of 55.6%, whereas the ORR in the non-HBV group was 36.8% (P = .35). Similarly, the DCR was 77.8% in the HBV group, as compared to 68.4% in the non-HBV group (P = .61). Additionally, HBV infection did not significantly affect OS (P = .54) and PFS (P = .64) in the unmatched cohort. Moreover, statistically significant differences regarding OS (P = .15) and PFS (P = .23) were also not detected after PSM.In conclusion, the HBV infection status did not impact the therapy response or prognosis of patients treated with PD-1 inhibitors. Further prospective studies are needed to corroborate these findings.

Abstract
BACKGROUND Previous works have observed that younger infants with chronic hepatitis B virus (HBV) infection are more responsive to antiviral treatment. However, the underlying mechanism remains unclear. In this study, the dynamic changes of HBV quasispecies in infants with immunoprophylaxis failure were investigated to provide virological explanations for clinical management on infantile antiviral therapy. METHODS Thirteen 7-month-old infants with immunoprophylaxis failure and their mothers were enrolled from a prospective cohort, and 8 of them were followed up to 3 years old. The sequences of HBV quasispecies were analyzed by the full-length genome clone-based sequencing, and compared among mothers and their infants at different ages. RESULTS The results revealed that the complexity, mutation frequency and genetic distance of HBV quasispecies decreased significantly at full-length, partial open reading frames and regulatory regions of HBV genome at nucleotide level in 7-month-old infants comparing with their mothers, whereas increased significantly to near the maternal level when infants grew up to 3 years old. Furthermore, similar changes were also found in Core, PreS2, RT and P regions of HBV genome at amino acid level, especially for potential NAs-resistant mutants in RT region and immune-escape mutants in Core and PreS2 regions. CONCLUSIONS This study uncovered the evolution of HBV quasispecies in infancy after mother-to-child transmission, which may provide the virological evidence for explaning that younger children are more responsive to antiviral therapy.

Abstract
JNJ-64794964 (JNJ-4964/AL-034/TQ-A3334), an oral toll-like receptor 7 agonist, is being investigated for the treatment of chronic hepatitis B (CHB), a condition with a high unmet medical need. The anti-hepatitis B (HBV) activity of JNJ-4964 was assessed preclinically in an adeno-associated virus vector expressing HBV (AAV/HBV) mouse model. Mice were treated orally with 2, 6 or 20 mg/kg of JNJ-4964 once-per-week for 12 weeks and then followed up for 4 weeks. At 6 mg/kg, a partial decrease in plasma HBV-DNA and plasma hepatitis B surface antigen (HBsAg) was observed, and anti-HBs antibodies and HBsAg-specific T cells were observed in 1/8 animals. At 20 mg/kg, plasma HBV-DNA and HBsAg levels were undetectable for all animals 3 weeks after start of treatment, with no rebound observed 4 weeks after JNJ-4964 treatment was stopped. High anti-HBs antibody levels were observed until 4 weeks after JNJ-4964 treatment was stopped. In parallel, HBsAg-specific immunoglobulin G-producing B cells and interferon-γ-producing CD4+ T cells were detected in the spleen. In 2/4 animals, liver HBV-DNA and HBV-RNA levels and liver hepatitis B core antigen expression dropped 4 weeks after JNJ-4964 treatment-stop. In these animals, HBsAg-specific CD8+ T cells were detectable. Throughout the study, normal levels of alanine aminotransferase were observed, with no hepatocyte cell death (end of treatment and 4 weeks later) and minimal infiltrations of B and T cells into the liver, suggesting induction of cytokine-mediated, non-cytolytic mechanisms.

Distinct Bile Acid Profiles in Patients With Chronic Hepatitis B Virus Infection Reveal Metabolic Interplay Between Host, Virus and Gut Microbiome. Front Med (Lausanne) 2021; 8:708495. [PMID: 34671614 PMCID: PMC8520922 DOI: 10.3389/fmed.2021.708495] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Accepted: 09/06/2021] [Indexed: 12/15/2022] Open
Abstract
Hepatitis B virus (HBV) can hijack the host bile acids (BAs) metabolic pathway during infection in cell and animal models. Additionally, microbiome was known to play critical role in the enterohepatic cycle of BAs. However, the impact of HBV infection and associated gut microbiota on the BA metabolism in chronic hepatitis B (CHB) patients is unknown. This study aimed to unveil the distinct BA profiles in chronic HBV infection (CHB) patients with no or mild hepatic injury, and to explore the relationship between HBV, microbiome and BA metabolism with clinical implications. Methods: Serum BA profiles were compared between CHB patients with normal ALT (CHB-NALT, n = 92), with abnormal ALT (CHB-AALT, n = 34) and healthy controls (HCs, n = 28) using UPLC-MS measurement. Hepatic gene expression in CHB patients were explored using previously published transcriptomic data. Fecal microbiome was compared between 30 CHB-NALT and 30 HCs using 16S rRNA sequencing, and key microbial function was predicted by PICRUSt analysis. Results: Significant higher percentage of conjugated BAs and primary BAs was found in CHB patients even without apparent liver injury. Combinatory BA features can discriminate CHB patients and HCs with high accuracy (AUC = 0.838). Up-regulation of BA importer Na+ taurocholate co-transporting peptide (NTCP) and down-regulation of bile salt export pump (BSEP) was found in CHB-NALT patients. The microbial diversity and abundance of Lactobacillus, Clostridium, Bifidobacterium were lower in CHB-NALT patients compared to healthy controls. Suppressed microbial bile salt hydrolases (BSH), 7-alpha-hydroxysteroid dehydrogenase (hdhA) and 3-dehydro-bile acid Delta 4, 6-reductase (BaiN) activity were found in CHB-NALT patients. Conclusion: This study provides new insight into the BA metabolism influenced both by HBV infection and associated gut microbiome modulations, and may lead to novel strategy for clinical management for chronic HBV infection.

Abstract
Since the identification of the first human oncogenic virus in 1964, viruses have been studied for their potential role in aiding the development of cancer. Through the modulation of cellular pathways associated with proliferation, immortalization, and inflammation, viral proteins can mimic the effect of driver mutations and contribute to transformation. Aside from the modulation of signaling pathways, the insertion of viral DNA into the host genome and the deregulation of cellular miRNAs represent two additional mechanisms implicated in viral oncogenesis. In this review, we will discuss the role of twelve different viruses on cancer development and how these viruses utilize the abovementioned mechanisms to influence oncogenesis. The identification of specific mechanisms behind viral transformation of human cells could further elucidate the process behind cancer development.

[PMID: 34430357 PMCID: PMC8350074 DOI: 10.21037/tlcr-21-455] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2021] [Accepted: 06/24/2021] [Indexed: 11/06/2022]
Abstract
Background The aim of this study was to evaluate the safety and survival outcomes of anti-programmed cell death (PD)-1/programmed cell death-ligand 1 (PD-L1) monotherapy in patients with advanced non-small cell lung cancer (NSCLC) and different hepatitis B virus (HBV) infection status. Methods Patients with advanced NSCLC and both chronic and/or resolved HBV infection who were treated with anti-PD-(L)1 monotherapy were retrospectively enrolled. The primary endpoint was the safety of PD-1/PD-L1 monotherapy, while the secondary endpoints included the survival outcomes. Results Of the 62 eligible patients, 10 (16.1%) were hepatitis B surface antigen (HBsAg) positive [chronic hepatitis B (CHB) infection] and 52 (83.9%) were HBsAg negative and HBcAb positive [resolved hepatitis B (RHB) infection]; 42 (67.7%) patients had at least 1 treatment-related adverse event (AE), with 4 patients (6.5%) developing grade 3 AEs and 6 (9.7%) developing hepatic AEs. One CHB patient experienced HBV reactivation during anti-PD-1 immunotherapy due to the interruption of antiviral prophylaxis. The objective response rate and durable clinical benefit (DCB) rate were 17.7% and 29.0%, respectively. Median overall survival (OS) and progression-free survival (PFS) were 23.6 months [95% confidence interval (CI): 14.4-32.8] and 2.1 months (95% CI: 1.2-3.0), respectively. The DCB rate was significantly higher in the CHB group than in the RHB group (60% vs. 23.1%; P=0.048). Patients with CHB experienced a longer PFS (8.3 vs. 2.0 months; P=0.103) and OS (35.0 vs. 18.2 months, P=0.119) than did RHB patients. Conclusions Anti-PD-(L)1 monotherapy was safe and effective in patients with NSCLC and HBV infection. This population should not be excluded from receiving immunotherapy in routine clinical practice or within clinical trials if HBV biomarkers are monitored and antiviral prophylaxis is properly used.

Abstract
INTRODUCTION The current clinical guidelines do not recommend antiviral therapy for subjects with positive hepatitis B virus (HBV)-DNA and normal alanine transaminase (ALT). In this study, we will assess the safety and efficacy of tenofovir alafenamide fumarate (TAF) in the treatment of adults with positive HBV-DNA and normal ALT, including long-term prognosis. METHODS AND ANALYSIS This study is a non-double-blind randomised controlled trial. Study participants will be randomised into the treatment group and the control group. In the treatment group, subjects will receive TAF monotherapy, while those in the control group will receive no antiviral treatment. Subjects will be followed up at the beginning of the study and every 12 or 24 weeks thereafter for review of laboratory findings and to record adverse events. The primary endpoint is the proportion of patients with serum hepatitis B surface antigen loss. ETHICS AND DISSEMINATION This study protocol was approved by the Ethics Committee of the Third Affiliated Hospital of Sun Yat-Sen University for Human Study (reference number [2019]02-599-01). The results of this study will be submitted for publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER NCT04231565.

B-Catenin Signaling Regulates the In Vivo Distribution of Hepatitis B Virus Biosynthesis across the Liver Lobule. J Virol 2021; 95:e0078021.

Abstract
β-catenin (Ctnnb1) supports high levels of liver gene expression in hepatocytes in proximity to the central vein functionally defining zone 3 of the liver lobule. This region of the liver lobule supports the highest levels of viral biosynthesis in wildtype HBV transgenic mice. Liver-specific β-catenin-null HBV transgenic mice exhibit a stark loss of high levels of pericentral viral biosynthesis. Additionally, viral replication that does not depend directly on β-catenin activity appears to expand to include hepatocytes of zone 1 of the liver lobule in proximity to the portal vein, a region of the liver that typically lacks significant HBV biosynthesis in wildtype HBV transgenic mice. While the average amount of viral RNA transcripts does not change, viral DNA replication is reduced approximately three-fold. Together, these observations demonstrate that β-catenin signaling represents a major determinant of HBV biosynthesis governing the magnitude and distribution of viral replication across the liver lobule in vivo. Additionally, these findings reveal a novel mechanism for the regulation of HBV biosynthesis that is potentially relevant to the expression of additional liver-specific genes. IMPORTANCE Viral biosynthesis is highest around the central vein in the HBV transgenic mouse model of chronic infection. The associated HBV biosynthetic gradient across the liver lobule is primarily dependent upon β-catenin. In the absence of β-catenin, the gradient of viral gene expression spanning the liver lobule is absent and HBV replication is reduced. Therefore, therapeutically manipulating β-catenin activity in the liver of chronic HBV carriers may reduce circulating infectious virions without greatly modulating viral protein production. Together, these change in viral biosynthesis might limit infection of additional hepatocytes while permitting immunological clearance of previously infected cells, potentially limiting disease persistence.

Am J Cancer Res 2021; 11:8362-8378.

Abstract
Rationale: Hepatitis B x protein (HBx) is required to initiate and maintain the replication of hepatitis B virus (HBV). Protein arginine methyltransferases 5 (PRMT5) negatively regulates HBV transcription. WD repeat domain 77 protein (WDR77) greatly enhances the methyltransferase activity of PRMT5. However, the role of WDR77 in the modulation of cccDNA transcription and HBV replication is poorly understood. In this study, we investigated the mechanism by which HBx modulated HBV replication involving WDR77 in the liver. Methods: A human liver-chimeric mouse model was established. Immunohistochemistry (IHC) staining, Western blot analysis, Southern blot analysis, Northern blot analysis, immunofluorescence assays, ELISA, RT-qPCR, CoIP assays, and ChIP assays were performed in human liver-chimeric mouse model, primary human hepatocytes (PHHs), HepG2-NTCP, dHepaRG and HepG2 cell lines. Results: HBV infection and HBx expression remarkably reduced the protein levels of WDR77 in human liver-chimeric mice and HepG2-NTCP cells. WDR77 restricted cccDNA transcription and HBV replication in PHHs and HepG2-NTCP cells. Mechanically, WDR77 enhanced PRMT5-triggered symmetric dimethylation of arginine 3 on H4 (H4R3me2s) on the cccDNA minichromosome to control cccDNA transcription. HBx drove the cellular DDB1-containing E3 ubiquitin ligase to degrade WDR77 through recruiting WDR77, leading to the disability of methyltransferase activity of PRMT5. Thus, HBx promoted HBV replication by driving a positive feedback loop of HBx-DDB1/WDR77/PRMT5/H4R3me2s/cccDNA/HBV/HBx in the liver. Conclusions: HBx attenuates the WDR77-mediated HBV repression by driving DDB1-induced WDR77 degradation in the liver. Our finding provides new insights into the mechanism by which HBx enhances HBV replication in the liver.

THE LANCET. INFECTIOUS DISEASES 2021; 21:823-833. [PMID: 33524314 DOI: 10.1016/s1473-3099(20)30692-7] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/13/2019] [Revised: 05/28/2020] [Accepted: 07/13/2020] [Indexed: 02/05/2023]
Abstract
BACKGROUND Antiviral therapy for patients with non-cirrhotic chronic hepatitis B and minimally raised alanine aminotransferase (ALT) is controversial. We aimed to investigate the efficacy and safety of tenofovir disoproxil fumarate in reducing the risk of disease progression in this patient population. METHODS TORCH-B is a multicentre, double-blind, placebo-controlled, parallel-group, randomised trial done at six teaching hospitals in Taiwan that enrolled patients with chronic hepatitis B. Eligible patients were aged 25-70 years and had substantial viraemia (viral DNA >2000 IU/mL) and minimally raised serum ALT concentrations more than one-fold but less than two-fold the upper limit of normal (ULN). Exclusion criteria included liver cirrhosis and previous antiviral treatment. Eligible participants were randomly assigned (1:1), stratified by site with a fixed block size of ten, to receive either 300 mg of oral tenofovir disoproxil fumarate or placebo once daily for 3 years. The participants, investigators, research coordinators, pathologists, laboratory personnel, and staff involved in patient care or assessment were masked to treatment assignment. 0·5 mg/day of oral entecavir was added to rescue acute hepatitis flare. The coprimary outcomes were change in necroinflammation severity on the Knodell scale and change in fibrosis stage on the Ishak scale and were evaluated in the modified intention-to-treat population, which comprised all patients with paired liver biopsies. Safety was evaluated in all patients who were randomly assigned. This trial is registered at ClinicalTrials.gov, NCT01522625, and is completed. FINDINGS From Jan 30, 2012, to Nov 10, 2015, 875 patients were screened and 160 were randomly assigned to receive either tenofovir disoproxil fumarate (n=79) or placebo (n=81). The coprimary outcomes were assessed in 146 patients (73 in each group). Liver fibrosis progressed (an increase of ≥1 stage) in 19 (26%, 95% CI 17-38) of 73 patients in the tenofovir disoproxil fumarate group and in 34 (47%, 35-59) of 73 patients in the placebo group (relative risk [RR] 0·56, 95% CI 0·35-0·88; p=0·013), whereas necroinflammation progressed (an increase of ≥2 points) in five (7%, 95% CI 2-15) patients in the tenofovir disoproxil fumarate group and in 12 (16%, 9-27) patients in the placebo group (RR 0·42, 95% CI 0·15-1·12; p=0·084). Two (3%) of 79 patients in the tenofovir disoproxil fumarate group and 13 (16%) of 81 patients in the placebo group had acute hepatitis flare requiring add-on entecavir (RR 0·16, 95% CI 0·04-0·68; p=0·013). The two groups were otherwise similar in occurrences of adverse events. No patients died. INTERPRETATION Tenofovir disoproxil fumarate reduces the risk of progression in liver fibrosis in patients with chronic hepatitis B and minimally raised ALT, but its effect on necroinflammation is non-significant.

Abstract
This study aimed to examine changes in levels of cytokine and T cell surface molecules in chronic hepatitis B (CHB) patients receiving sequential interferon therapy following 1-year nucleos(t)ide analogs (NAs) treatment. Cytokine levels were measured in 30 patients, and T cell surface molecule expression was measured in 48 patients receiving sequential interferon therapy and 24 patients only receiving NA mono-therapy. An HBsAg titer of <0.05 IU/ml was defined as a "functional cure." In the cured group (HBsAg < 0.05 IU/ml), a decreasing probability was observed in IFN-γ (after Week 0), and IL-22 and IP-10 (after Week 12). In the non-cured group (HBsAg ≥ 0.05 IU/ml), a probability of slightly decreasing was observed for IFN-γ (after Week 12), and a probability of increasing IP-10 concentration (after Week 0) was observed. Generalized estimating equation (GEE) analyses showed significant differences in the levels of IL-10, IL-23, CCL-3, IL-1β, IL-2, and IL-12P70 between the two groups. In GEE analysis, there were significant differences in expressions of CD45RO+ between the cured group and the non-cured group. The frequencies of T cells expressing Tim-3, CD62L, and CD152 were significantly lower in the sequential interferon therapy group than in the NA mono-therapy group. Changes in cytokine levels (IFN-γ, IP-10, IL-10, IL-23, CCL-3, IL-1β, IL-2, and IL-12P70) and T cell surface molecules (CD45RO+ ) may predict HBsAg seroconversion in CHB patients receiving sequential interferon therapy. The period from Weeks 12 to 24 during sequential interferon therapy may be a critical time of immune status change.

Abstract
PURPOSE OF REVIEW Lack of availability of donor organs is a constant challenge that patients and providers face in transplantation. To address this shortage, donors that test positive for hepatitis B, in particular those with resolved infection, have been increasingly utilized in clinical practice. We review here the potential risks for the recipient and the advances in hepatitis B management that have made use of these donors a well tolerated and advisable proposition. RECENT FINDINGS As routine administration of antiviral prophylaxis in the posttransplant setting among those deemed high risk for transmission, outcomes for recipients of hepatitis B donors, including liver transplant recipients, have been comparable to uninfected donors. Universal hepatitis B nucleic acid testing of donors has also enhanced our ability to accurately inform recipients regarding transmission risk. Appropriate use of prophylaxis and careful monitoring for transmission posttransplant is key to ensuring no adverse outcomes occur. SUMMARY Treatment of hepatitis B has evolved over the past two decades. Expanding the donor pool with hepatitis B donors is now well tolerated, ethical, and advantageous to the transplant community at large. A clear discussion with recipients on the substantial benefit and low harm of using hepatitis B donors will lead to greater acceptance and utilization of these organs.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a chronic inflammatory condition related to multiple systemic diseases and infections. METHODS This retrospective cross-sectional study from 1999 to 2015 used the database of Clalit Health Services, the largest managed care organization in Israel, to explore the association between HS and hepatitis B and C. Sociodemographic and clinical information was compared using χ2 tests for sex and socioeconomic status and t-tests for age. Logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) to compare the odds of hepatitis B and C in those with and without HS. RESULTS In multivariate analysis controlling for sex, age as a continuous variable, Arab ancestry, and history of drug abuse, HS was associated with a 1.87-fold increased odds (95% CI 1.11-3.17, P = 0.019) of hepatitis B (HBV). HS was also associated with HCV in multivariate analysis controlling for sex, age per year, Arab ancestry, alcohol use, and drug use, with a 1.74-fold increased odds (95% CI 1.05-2.89, P = 0.032) of hepatitis C (HCV) among those with HS as compared to controls. CONCLUSIONS This study demonstrated an association between HS and both hepatitis B and hepatitis C.

Abstract
PURPOSE OF REVIEW The last 2 years have seen significant developments in virus-positive liver transplantation. This review provides an updated account of the transplantation of hepatitis C virus (HCV), hepatitis B virus (HBV) and HIV-positive livers, with a specific focus on studies published in the last 18 months. RECENT FINDINGS The advent of highly efficacious direct acting antiviral agents, nucleos(t)ide analogues and a continued organ shortage have led to the well tolerated utilization of HCV, HBV and HIV-positive organs. There has been a significant increase in the transplantation of HCV seropositive and NAT+ organs into HCV-negative recipients, without compromising patient or graft survival. Early reports of HBV core antibody (HBVcAb), HBV surface antigen (HBVsAg) positive and NAT+ donors are growing in the USA with promising results. Similarly, small studies have described the use of HIV-positive to HIV-positive liver transplantation without concerns for superinfection. SUMMARY HCV, HBV and HIV-positive liver transplantations can be accomplished safely and are associated with equivalent outcomes when paired with appropriate recipients. The practice of virus positive liver transplantation should be encouraged to combat the ongoing organ shortage.

Lipid Storage and Interferon Response Determine the Phenotype of Ground Glass Hepatocytes in Mice and Humans. Cell Mol Gastroenterol Hepatol 2021; 12:383-394. [PMID: 33766783 PMCID: PMC8255940 DOI: 10.1016/j.jcmgh.2021.03.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Revised: 03/17/2021] [Accepted: 03/17/2021] [Indexed: 12/10/2022]
Abstract
BACKGROUND AND AIMS A histopathological hallmark of chronic hepatitis B virus (HBV) infection is the presence of ground glass hepatocytes (GGHs). GGHs are liver cells that exhibit eosinophilic, granular, glassy cytoplasm in light microscopy and are characterized by accumulation of HBV surface (HBs) proteins in the endoplasmic reticulum (ER). More important, GGHs have been accepted as a precursor of HCC and may represent preneoplastic lesions of the liver. METHODS Here we show that the reason for ground glass phenotype of hepatocytes in patients with chronic hepatitis B (CHB) and in HBs transgenic mice is a complex formation between HBs proteins and lipid droplets (LDs) within the ER. RESULTS As fat is a main component of LDs their presence reduces the protein density of HBs aggregates. Therefore, they adsorb less amount of eosin during hematoxylin-eosin staining and appear dull in light microscopy. However, after induction of interferon response in the liver LDs were not only co-localized with HBs but also distributed throughout the cytoplasm of hepatocytes. The uniform distribution of LDs weakens the contrast between HBs aggregates and the rest of the cytoplasm and complicates the identification of GGHs. Suppression of interferon response restored the ground glass phenotype of hepatocytes. CONCLUSIONS Complex formation between HBs and LDs represents a very important feature of CHB that could affect LDs functions in hepatocytes. The strain specific activation of the interferon response in the liver of HBs/c mice prevented the development of GGHs. Thus, manipulation of LDs could provide a new treatment strategy in the prevention of liver cancer.

Relative DNA Methylation and Demethylation Efficiencies during Postnatal Liver Development Regulate Hepatitis B Virus Biosynthesis. J Virol 2021; 95:JVI.02148-20. [PMID: 33361417 DOI: 10.1128/jvi.02148-20] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Accepted: 12/09/2020] [Indexed: 12/18/2022] Open
Abstract
Hepatitis B virus (HBV) transcription and replication increase progressively throughout postnatal liver development with maximal viral biosynthesis occurring at around 4 weeks of age in the HBV transgenic mouse model of chronic infection. Increasing viral biosynthesis is associated with a corresponding progressive loss of DNA methylation. The loss of DNA methylation is associated with increasing levels of 5-hydroxymethylcytosine (5hmC) residues which correlate with increased liver-enriched pioneer transcription factor Forkhead box protein A (FoxA) RNA levels, a rapid decline in postnatal liver DNA methyltransferase (Dnmt) transcripts, and a very modest reduction in ten-eleven translocation (Tet) methylcytosine dioxygenase expression. These observations are consistent with the suggestion that the balance between active HBV DNA methylation and demethylation is regulated by FoxA recruitment of Tet in the presence of declining Dnmt activity. These changes lead to demethylation of the viral genome during hepatocyte maturation with associated increases in viral biosynthesis. Consequently, manipulation of the relative activities of these two counterbalancing processes might permit the specific silencing of HBV gene expression with the loss of viral biosynthesis and the resolution of chronic HBV infections.IMPORTANCE HBV biosynthesis begins at birth and increases during early postnatal liver development in the HBV transgenic mouse model of chronic infection. The levels of viral RNA and DNA synthesis correlate with pioneer transcription factor FoxA transcript plus Tet methylcytosine dioxygenase-generated 5hmC abundance but inversely with Dnmt transcript levels and HBV DNA methylation. Together, these findings suggest that HBV DNA methylation during neonatal liver development is actively modulated by the relative contributions of FoxA-recruited Tet-mediated DNA demethylation and Dnmt-mediated DNA methylation activities. This mode of gene regulation, mediated by the loss of DNA methylation at hepatocyte-specific viral and cellular promoters, likely contributes to hepatocyte maturation during liver development in addition to the postnatal activation of HBV transcription and replication.

Abstract
Background and Aim Although tenofovir alafenamide (TAF), as well as entecavir (ETV), is widely used as first‐line treatment for patients with chronic hepatitis B, there are only a few studies comparing sequential therapy from ETV to TAF and continuous ETV monotherapy in patients with maintained virologic response to ETV. Methods In a retrospective multicenter study, we investigated the efficacy and safety of sequential therapy from ETV to TAF (ETV‐TAF group) and compared them with continuous ETV monotherapy (ETV group), using propensity score matching, in chronic hepatitis B patients. Results From 442 patients, we analyzed 142 patients from each group comprising 71 patients matched for several data, including age, HBV genotype, hepatitis B envelope antigen, cirrhosis, alanine aminotransferase, platelet count, prior ETV monotherapy period, and hepatitis B surface antigen (HBsAg) change during prior ETV monotherapy. In the ETV‐TAF group, HBsAg levels significantly decreased from baseline to 48 weeks after switching to TAF (−0.02 log IU/mL, P = 0.038). HBcrAg levels also significantly decreased after switching to TAF (−0.1 log IU/mL, P = 0.004). However, there were no significant differences in the reduction of HBsAg and HBcrAg levels between the ETV‐TAF and ETV groups. There was no significant difference in the change of estimated glomerular filtration rate levels from baseline to 48 weeks between the two groups. Conclusions The present study indicated that the efficacy, especially of the HBsAg‐reducing action, and safety of sequential therapy from ETV to TAF were similar to those of continuous ETV monotherapy among chronic hepatitis B patients with maintained virologic response to ETV.

Abstract
Worldwide, millions of people suffer from hepatitis B virus (HBV) infection, putting them at a high risk of death from liver cirrhosis and cancer. Although effective anti-HBV drugs have been developed, current drugs have some limitations, as most of them have a risk of significant side effects. Therefore, the discovery of safe and effective anti-HBV drugs is still needed. Natural compounds are considered sources of novel, safe and effective therapeutics. In this study, we screened a library of Kampos, traditional herbal medicines, for suppression of HBV production. Among them, we found that maoto reduced extracellular HBV DNA but not extracellular HBsAg during HBV infection, suggesting that it suppressed HBV production by interfering with HBV nucleocapsid incorporation into viral particles. Furthermore, we revealed that maoto reduced the expression of a host gene, Tropomyosin β chain (TPM2), whose downregulation also suppressed HBV production, similarly to maoto. Since the safety of maoto has been already confirmed, maoto can be considered a candidate anti-HBV agent if the effect is confirmed in vivo. In addition, our findings also suggest TPM2 as a novel molecular target for the development of anti-HBV agents.

Abstract
Objective Pegylated-interferon monotherapy is the standard treatment for patients with chronic hepatitis B; however, the factors associated with its therapeutic effects remain unclear. Methods Patients with chronic hepatitis B were treated with pegylated interferon α-2a for 48 weeks. We evaluated the kinetics of hepatitis B surface antigen (HBsAg) during treatment and follow-up periods and the factors associated with an HBsAg response (defined as a change in HBsAg of ≥-1 log IU/mL from baseline). Results The study population comprised 50 patients. The median baseline levels of hepatitis B virus DNA and HBsAg were 5.00 and 3.40 log IU/mL. The median values of HBsAg reduction from baseline were -0.44 (n=48), -0.41 (n=40), and -0.68 (n=11) log IU/mL at the end of treatment and at 48 and 144 weeks post-treatment, respectively. The rates of HBsAg response were 24.0% and 22.5% at the end of treatment and at 48 weeks post-treatment, respectively. A multivariate analysis identified HBsAg <3.00 log IU/mL as an independent baseline factor contributing to the HBsAg response at the end of treatment and 48 weeks post-treatment (p=1.07×10-2 and 4.42×10-2, respectively). There were significant differences in the reduction of the HBsAg levels at 12 weeks of treatment and in the incidence of serum ALT increase during treatment between patients with and without an HBsAg response. Conclusion These findings suggest that the baseline HBsAg level, HBsAg kinetics at 12 weeks of treatment, and ALT increase during treatment are important factors contributing to the HBsAg response in pegylated interferon α-2a monotherapy for patients with chronic hepatitis B.

Abstract
Both tenofovir disoproxil fumarate (TDF) and entecavir (ETV) are accepted as first-line treatments for chronic hepatitis B (CHB). However, there are few randomized studies comparing their efficacy. The primary aim of this study was to compare the efficacy of TDF and ETV using a network meta-analysis of randomized trials. The secondary aim was to additionally include propensity-matched cohort studies in a conventional meta-analysis. We systematically searched PubMed, EMBASE, Cochrane Library and Web of Science for published English-language randomized and propensity-matched studies between 1/1/2000 and 4/2/2020. Outcomes included undetectable HBV DNA, ALT normalization and HBeAg seroconversion at 48 weeks. We excluded patients who had co-infection or significant prior treatment with antivirals. 13 517 participants from 16 studies (11 RCTs, n = 2675; five propensity-matched cohort studies, n = 10 842) were included. Virological response at 48 weeks was higher in patients receiving TDF compared to ETV using both the network meta-analytic approach (OR 1.69, P < .001) and the conventional meta-analysis including propensity-matched cohort studies (OR 1.40, P < .001). On subgroup analysis, this difference was only significant in HBeAg-positive patients (OR 1.81, P = .037). There was limited evidence to suggest a higher rate of ALT normalization with ETV (OR 0.74, P = .07). There was no difference in rates of HBeAg seroconversion between the two antivirals. TDF is more likely than ETV to induce virological response at 48 weeks in treatment-naïve CHB patients. Future studies should focus on elucidating associations between early and sustained virological response with adverse patient outcomes including development of HCC or cirrhosis.

Abstract
Hepatitis B viral (HBV) DNAs, including covalently closed circular DNA (cccDNA) and integrated HBV DNA forms, are considered to be primary contributors to the development and progression of HBV-associated liver diseases. However, it remains largely unclear how HBV DNAs communicate with human chromatin. Here we employed a highly sensitive technology, 3C-high-throughput genome-wide translocation sequencing (3C-HTGTS), to globally identify HBV DNA-host DNA contacts in cellular models of HBV infection. HBV DNA does not randomly position in host genome but instead preferentially establishes contacts with the host DNA at active chromatin regions. HBV DNA-host DNA contacts are significantly enriched at H3K4me1-marked regions modified by KMT2C/D; this histone modification is also observed in the HBV cccDNA mini-chromosome and strongly influences HBV transcription. On the other hand, chromatin loop formed by integrated HBV DNA with host genomic DNA was found in transcriptionally active regions. Furthermore, HBV infection influences host gene expression accompanied with HBV DNA-host DNA contacts. Our study provides a 3D landscape of spatial organization of cccDNA and integrated HBV DNA within the human genome, which lays the foundation for a better understanding of the mechanisms how HBV involves in liver disease development and progression.

Abstract
Immunization programmes against hepatitis-B are being carried out since more than three decades but still HBV is a major public health problem. Hepatitis B virus (HBV) genome consists of circular and partial double stranded DNA. Due to partial double stranded DNA, it uses an RNA intermediate during replication. This replicative strategy of HBV and lack of polymerase proofreading activity give rise to error occurrences comparable to retroviruses. The low fidelity of polymerase, overlapping reading frames and high replication rate produces many non-identical variants at every cycle of replication. Therefore, HBV spreads with mutations and variations. The mutations have been reported both in non-structural as well as structural genes of HBV genome. Recent advances in molecular biology have made easier to analyse these mutations. Hepatitis B antiviral therapy and immunization are all influenced by genetic variability. The analysis and understanding of these mutations are important for therapy against hepatitis B and updating of diagnostic tools. The present review discusses about mutations occurring in whole HBV genome. The mutation occurring both in structural and non-structural genes and non-coding regions have been described in details. It is much more informative because most of literature available, covers only individual gene or DNA regions of HBV.

Abstract
PURPOSE OF REVIEW The burden of chronic hepatitis B (HBV) remains disproportionately high among people living with HIV (PLWH) despite the advent of HBV vaccination and HBV-active antiretroviral therapy (ART). This review summarizes new insights and evolving issues in HIV-HBV coinfection. RECENT FINDINGS HBV-HIV coinfection is still a leading cause of cirrhosis, hepatocellular carcinoma (HCC) and liver-related mortality more than a decade after the approval of tenofovir. While tenofovir-based ART has been shown to improve rates of HBV virologic suppression and halt fibrosis progression, the long-term benefits on the prevention of end-stage liver disease or HCC in HIV-HBV coinfection have yet to be convincingly demonstrated in PLWH. Missed opportunities for HBV vaccination persist despite evidence of ongoing risk for HBV infection in this population. SUMMARY Even as we work towards HBV elimination and functional cure, ongoing efforts should focus on optimizing risk stratification as well as uptake of HBV-active antiviral therapy and HBV immunization in this priority population.
