Abstract
BACKGROUND Chronic hepatitis B virus (HBV) infection is a major health problem for all Indigenous Australians. Post-2000, Hepatitis B surface antigen prevalence has decreased, although remaining four times higher among Indigenous compared with non-Indigenous people. AIMS This study aimed to characterise the HBV from Indigenous populations in Queensland and the Torres Strait Islands. METHODS Serum samples were collected, with consent, from people within Queensland Indigenous communities prior to 1990 as part of the Queensland Health vaccination programme. Ethics approval was subsequently obtained to further characterise the HBV from 93 of these stored samples. HBV DNA was extracted and genotype was obtained from 82 samples. HBV full genome sequencing was carried out for a subset of 14 samples. RESULTS Seventy-eight samples were identified as genotype C (2 × C12, 3 × C13 and 73 × C14), one sample as genotype A (A2) and three samples as genotype D (1 × D2, 1 × D3 and 1 × D4). The HBV/C sequences identified were most closely related to sequences isolated from Papua New Guinea and Indonesia (Papua Province). CONCLUSIONS The HBV isolated from the Torres Strait Islanders was notably different to the HBV/C4 strain isolated from Indigenous people of mainland northern Australia, with no evidence of recombination. This reflects the differences in culture and origin between Torres Strait Islanders and mainland Indigenous people.

Abstract
Prevention of mother-to-child transmission of hepatitis B virus (HBV) infection is a cornerstone of efforts to support progress towards elimination of viral hepatitis. Current guidelines recommend maternal screening, antiviral therapy during the third trimester of high-risk pregnancies, universal and timely HBV birth dose vaccination, and post-exposure prophylaxis with hepatitis B immunoglobulin for selected neonates. However, serological and molecular diagnostic testing, treatment and HBV vaccination are not consistently deployed, particularly in many high endemicity settings, and models predict that global targets for reduction in paediatric incidence will not be met by 2030. In this article, we briefly summarise the evidence for current practice and use this as a basis to discuss areas in which prevention of mother-to-child transmission can potentially be enhanced. By reducing health inequities, enhancing pragmatic use of resources, filling data gaps, developing advocacy and education, and seeking consistent investment from multilateral agencies, significant advances can be made to further reduce vertical transmission events, with wide health, societal and economic benefits.

Abstract
BACKGROUND AND AIM Staining for hepatitis B viral antigens is often done in liver biopsies from patients with chronic hepatitis B, but its correlates with clinical phenotypes are not well described. METHODS Biopsies were collected from a large cohort of adults and children with chronic hepatitis B viral infection through the Hepatitis B Research Network. Immunohistochemical staining of sections was done for hepatitis B surface antigen (HBsAg) and hepatitis B core antigen (HBcAg) and then centrally read by the pathology committee. The degree of liver injury and pattern of staining were then correlated with clinical characteristics, including the clinical phenotype of hepatitis B. RESULTS Biopsies from 467 subjects were studied, including 46 from children. Immunostaining for HBsAg was positive in 417 (90%) with scattered hepatocyte staining being the most common pattern. HBsAg staining correlated best with serum levels of HBsAg and hepatitis B viral DNA; the absence of HBsAg staining was often a prelude to loss of HBsAg from serum. HBcAg staining was positive in 225 (49%), and, while cytoplasmic staining was more frequent than nuclear staining, both nuclear and cytoplasmic positivity were often seen in the same specimen. Staining for HBcAg correlated with both level of viremia and liver injury. No biopsies from inactive carriers had stainable HBcAg, while 91% of the biopsies from those with hepatitis B e antigen-positive chronic hepatitis B stained positively for HBcAg. CONCLUSION Immunostaining for hepatitis B viral antigens may yield helpful insights into liver disease pathogenesis but appears to add little to commonly used serological and biochemical blood tests.

Hepatitis B e antigen and e antibody in a multi-ethnic cohort of adult chronic hepatitis B virus patients followed at a single liver unit for a period of 20 years. J Viral Hepat 2022; 29:879-889.

Abstract
Hepatitis B virus e antigen (HBeAg) loss and the appearance of antibodies to HBeAg (anti-HBe) are favourable events in the history of chronic hepatitis B virus (CHB) infection. Most CHB patients have the HBeAg/anti-HBe profiles +/- or -/+, and little is published on the derivation or fate of the +/+ and -/- profiles. We have used electronically accessible patient data to study the HBeAg and anti-HBe profiles of a multi-ethnic cohort of adult HBV patients seen at a single centre over a period of more than 20 years. 3594 HBsAg-positive patients were identified and patients with viral coinfection or acute HBV infection were excluded. Cross-sectional and longitudinal analyses of HBeAg/anti-HBe status were undertaken. Compared with White or Black patients, Chinese and Asian patients are more likely to be HBeAg positive during child-bearing years. Patients with +/+ profile are likely to undergo HBeAg loss and seroconversion during relatively short follow-up. Chinese patients have a relatively increased rate of seroconversion. For HBeAg-positive patients, the risk of seroconversion diminishes with advancing age. Despite HBeAg loss, seroconversion is seldom observed after age 60 years. The proportion of HBV patients with -/- increases with age, and most acquire this profile by HBeAg loss but without antecedent seroconversion. -/- patients can lose HBsAg and develop anti-HBs. It was not possible to demonstrate a favourable impact of antiviral treatment on the rate of HBeAg seroconversion.

Abstract
BACKGROUND AND AIMS Chronic kidney disease (CKD) usually occurs during the chronic infection of hepatitis B virus (HBV). However, the risk factors of CKD in an HBV population have not been completely demonstrated. Our present study aimed to investigate the risk factors of CKD in chronic HBV infection using a hospital based cross-sectional study in the northern area of China. METHODS During January 2013 to December 2017, a total of 94 patients with CKD complicated by chronic HBV infection were consecutively enrolled in the study, as well as 548 age- and sex-matched hepatitis B patients without CKD who were enrolled as controls. Univariate and multivariate regression analyses were used to determine the effects of each variable after adjusting for cofounding factors. RESULTS Multivariate analysis showed that HBeAg-positive status (odds ratio [OR]=2.099, 95% CI 1.128-3.907), dyslipidemia (OR: 3.025, 95% CI 1.747-5.239), and hypertension (OR: 12.523, 95% CI 6.283-24.958) were independently associated with the incidence of CKD, while duration of HBV infection (≥240 months) (OR: 0.401, 95% CI 0.179-0.894), Log10 HBsAg (OR: 0.514, 95% CI 0.336-0.786), and coronary heart disease (OR: 0.078, 95% CI 0.008-0.768) were protective factors for the incidence of CKD. Duration of HBV infection, Log10 HBsAg, HBeAg-positive status and dyslipidemia remained the risk factors for CKD after adjusting for diabetes mellitus, hypertension, and coronary heart disease. CONCLUSIONS Duration of HBV infection, Log10 HBsAg, HBeAg-positive status and dyslipidemia contributed to the incidence of CKD during chronic HBV infection in a Chinese population.

Abstract
The aim of our study was to determine the distribution of hepatitis B virus (HBV) genotypes and subgenotypes in ethnic minorities in Yunnan province to provide evidence supporting the theoretical basis for hepatitis B prevention and control. We obtained serum samples and demographic data from 765 individuals reported by Yunnan province who had either acute or chronic HBV infection and were from one of 20 ethnic minority populations: Achang, Bai, Brown, Tibetan, Dai, Deang, Dulong, Hani, Hui, Jingpo, Lahu, Yi, Lisu Miao, Naxi, Nu, Pumi, Wa, Yao, or Zhuang people. We sequenced the HBV DNA and determined the genotypes and subgenotypes of the isolated HBVs. We mapped the genotype and subgenotype distribution by ethnic minority population and conducted descriptive analyses. There were four genotypes among the 20 ethnic groups: genotype B (21.3% of samples), C (76.6%), D (1.8%) and I (0.3%). The most common subgenotype was C1. There were no genotype differences by gender (P = 0.954) or age (P = 0.274), but there were differences by region (P < 0.001). There were differences in genotype distribution (P < 0.001) and subgenotype distribution (P = 0.011) by ethnic group. Genotype D was most prominent in Tibet and most HBV isolates were C/D recombinant viruses. The only two genotype I virus isolates were in Zhuang people. Susceptibility and geographic patterns may influence HBV prevalence in different ethnic populations, but additional research is needed for such a determination.

Abstract
Hepatitis B e antigen (HBeAg) is a soluble viral protein in plasma of patients with hepatitis B virus infection. HBeAg loss is an important first stage of viral antigen clearance. We determined the rate and predictors of HBeAg loss in a North American cohort with chronic hepatitis B viral infection (CHB). Among children and adults with CHB and without HIV, HCV or HDV co-infection enrolled in the Hepatitis B Research Network prospective cohort studies, 819 were HBeAg positive at their first assessment (treatment naïve or >24 weeks since treatment). Of these, 577 (200 children, 377 adults) were followed every 24-48 weeks. HBeAg loss was defined as first HBeAg-negative value; sustained HBeAg loss was defined as ≥2 consecutive HBeAg-negative values ≥24 weeks apart. During a median follow-up of 1.8 years, 164 participants experienced HBeAg loss, a rate of 11.4 (95% CI, 9.8-13.3) per 100 person-years. After adjustment for confounders, HBeAg loss rate was significantly higher in males than females, in older than younger individuals, in Whites or Blacks than Asians, in those with genotype A2 or B versus C, and in those with basal core promoter/pre-core mutations versus wild type. Additionally, during follow-up, an ALT flare and a lower quantitative HBsAg, quantitative HBeAg or HBV DNA level predicted higher rates of HBeAg loss. The majority (88%) with HBeAg loss had sustained HBeAg loss. In conclusion, a number of specific demographic, clinical and viral characteristics impacted rate of HBeAg loss and may prove useful in design and interpretation of future therapeutic studies.

Abstract
BACKGROUND In chronic hepatitis B (CHB) viral infection, e antigen positivity (HBeAg+) is associated with high levels of viral replication and infectivity. Furthermore, HBeAg-positive CHB is associated with a liver disease spectrum ranging from none to severe. AIM To assess whether the level of circulating HBeAg is associated with different clinical presentations of HBeAg-positive CHB. METHODS A cross-sectional analysis was conducted among HBV mono-infected participants enrolled in Hepatitis B Research Network (HBRN) cohorts to explore clinical and virological associations with quantitative HBeAg (qHBeAg). RESULTS Among 763 HBeAg+ participants (56% female; 85% Asian; median age 26 years), multivariable median regression modelling significantly associated qHBeAg with liver injury (inverse qHBeAg association with ALT p<.001 and APRI p<.001), and with both race and age (p=0.01). Among Asians, qHBeAg was inversely related to age; a relationship less clear among Blacks and Whites. Among Asians also, median qHBeAg levels were higher among those infected with HBV genotype C versus B (p<0.001), suggesting causal virologic differences. Across all races, median qHBeAg was higher in women (p=.01). Independent of sex, age, race and HBV genotype, qHBeAg was higher in participants with predominant wild-type versus basal core promoter and/or precore 'stop' viral variants (p<0.001). CONCLUSION Lower qHBeAg was observed among HBRN participants with the greatest degree of liver injury independent of demographics and HBV genotype. These data support longitudinal studies to examine the role of qHBeAg in modulating the host immune response and predicting the outcomes of chronic HBV infection.

Abstract
BACKGROUND AND AIMS Hepatitis B virus (HBV) precore (PC) and dual basal core promoter (BCP) mutations halt and down-regulate hepatitis B e antigen (HBeAg) production respectively. PC mutation is rarely associated with HBV genotype A. We sought to examine the association of these variants with HBV genotypes, age, and HBeAg status in a racially diverse population in North America. Prospective study included 1,036 (808 adults, 228 children) participants in the Hepatitis B Research Network. PC and BCP variants were determined by Sanger sequencing, and dominant HBV species (>50%) were reported. APPROACH AND RESULTS Median age was 36.3 years (range, 2-80), 44.6% HBeAg(+), 74.2% Asians, 13.3% black, and 9.7% white. The dominant PC variant was present in 29.4% participants, including 20 with subgenotype A1 or A2. Seventeen of 20 participants with genotype A and PC had a compensatory C1858T mutation. In the HBeAg(+) cohort, the prevalence of PC and/or BCP variants increased from 14.4% in the first two decades to 51% after 40 years of age. Among those aged 2-18, 52% and 83% with dominant PC and BCP variants were HBeAg(+) compared to 3.8% and 29% in the >40 years age group. HBeAg clearance rates were significantly higher for those with dominant PC or BCP variants: 24.4 and 15.0 per 100 person-years compared to 6.0 in wild-type HBV (P < 0.0001). CONCLUSIONS PC variants can be present in HBV genotype A and are usually associated with C1858T, which preserves the pregenome encapsidation sequence. Selection of PC and BCP variants occurred at a young age, with increasing prevalence across age groups. HBeAg(+) participants with dominant PC and BCP variants progressed to the HBeAg(-) phase of chronic HBV infection significantly faster. This finding has potential clinical and therapeutic implications.

Abstract
Studies of human hepatitis B virus (HBV) immune pathogenesis are hampered by limited access to liver tissues and technologies for detailed analyses. Here, utilizing imaging mass cytometry (IMC) to simultaneously detect 30 immune, viral, and structural markers in liver biopsies from patients with hepatitis B e antigen+ (HBeAg+) chronic hepatitis B, we provide potentially novel comprehensive visualization, quantitation, and phenotypic characterizations of hepatic adaptive and innate immune subsets that correlated with hepatocellular injury, histological fibrosis, and age. We further show marked correlations between adaptive and innate immune cell frequencies and phenotype, highlighting complex immune interactions within the hepatic microenvironment with relevance to HBV pathogenesis.

Abstract
INTRODUCTION To eliminate viral hepatitis by 2030, the World Health Organization (WHO) launched the first global health sector strategy on viral hepatitis, with particular focus given to hepatitis B and C in 2016. To achieve the reduction of mortality in children, it is indispensable to know which children should be treated and how to treat them. AREA COVERED In this article, the authors review the antiviral treatment of children with chronic hepatitis B virus (HBV) infection including antivirals available for children with chronic HBV infection. EXPERT OPINION The approvals of nucleos(t)ide analogues (NAs) and pegylated interferon (PEG-IFN) for children have lowered a hurdle to the initiation of antiviral treatment in children. The international guidelines use nearly the same criteria of antiviral treatment for children with chronic HBV infection, but the WHO guidelines provide a cautious stance on the antiviral treatment of children. Not only PEG-IFN but also NAs with a high genetic barrier to drug resistance should be the first-line treatment for children. In settings with limited medical resources, NAs can be the first-line treatment for children. Although the concept of an 'immune-tolerant phase' is challenged, evidence is not sufficient to recommend the treatment of HBeAg-positive immune-tolerant children.

Abstract
Immunization with hepatitis B vaccine is an effective measure for prevention and control of hepatitis B Virus (HBV) infection. Although lots of efforts to improve the effect of hepatitis B vaccine have been made, the function of human beta defensin 2 (hBD2) on hepatitis B vaccine keeps unclear. In this article, we report that hBD2 not only promoted the activation and maturation of immature dendritic cells (iDCs) by increasing MHC II and CD86 expression, but it also significantly upregulated the mRNA level of IL-6 and IL-12B in mouse bone marrow-derived dendritic cells. The serum concentrations of IFN-γ in mice stimulated with 300 ng hBD2 increased from 25.21 to 42.04 pg/mL, with a time extension from 4 to 12 h post-injection. During the process of three times immunization (1, 14, 28 days) with 3 μg hepatitis B vaccine combined with or without 300 ng hBD2 with a 2 week interval in BALB/c mice, the antibody against HBsAg (HBsAb) concentration in serum at every time point of observation in the combined group was statistically higher than the hepatitis B vaccine group. The serum concentration of IgG2a subclass HBsAb on the 14th day post last injection in the combined group was significantly higher than the hepatitis B vaccine group. Further, the splenic cells from the mice treated with both hBD2 and hepatitis B vaccine possessed a greater ability to produce a surface antigen of hepatitis B virus (HBsAg) specific IFN-γ than those treated with hepatitis B vaccine alone. The percentages of CD3+/CD4+ T cells and CD3+/CD8+ T lymphocytes in spleens from the mice treated with 300 ng hBD2 were statistically higher than the phosphate buffered saline group. These data suggest that hBD2 improves iDC maturation and the immune efficiency of hepatitis B vaccine in BALB/c mice.

J Viral Hepat 2020; 27:1344-1351. [PMID: 32853482 DOI: 10.1111/jvh.13382] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2020] [Revised: 07/09/2020] [Accepted: 08/11/2020] [Indexed: 02/06/2023]
Abstract
The aims of this prospective study were as follows: (1) to describe the natural history of chronic hepatitis B virus (HBV) infection in a large cohort of untreated children followed at a single centre and (2) to evaluate whether or not the new European Association for the Study of Liver (EASL) classification for the phases of HBV infection in adults can be used for children. All children who presented at the Liver Unit of our hospital from 1 January 1987 to 31 December 2019 and were diagnosed with chronic HBV infection were enrolled. The final sample consisted of 152 children. The median duration of the follow-up was 83 months (range 7-232). At baseline, 125 patients (82.2%) were HBeAg positive (85.3% abnormal alanine aminotransferase (ALT) levels), and 24 (15.8%) were HBeAg-negative (93.3% abnormal ALT). At the end of the observation period, 62 of the HBeAg-positive patients (40.7%) achieved HBeAg seroconversion (median age 9.45 years, range 0.8-19) and 2 (1.4%) achieved HBsAg seroconversion. Elevated ALT serum levels at baseline (P = .011), lower baseline HBV DNA levels (P < .001) and Asian ethnicity (P = .0001) were identified as predisposing factors towards HBeAg seroconversion. EASL criteria could not be applied to 43.3% and 43.5% of the children at baseline and at end of observation, respectively, that were grouped into an undetermined phenotype category. According to the results of the present study, the new EASL guidelines for adults with HBV infection cannot be applied in a satisfactory manner in children.

Abstract
There is a need for an interpretable, accurate and interactions-considered model for predicting hepatitis B surface antigen (HBsAg) seroclearance. We aimed to construct a Bayesian network (BN) model using available medical records to predict HBsAg seroclearance in chronic hepatitis B (CHB) patients, and to evaluate the model's performance. This was a case-control study. A total of 1966 consecutive CHB patients (mean age 39.04 ± 11.23 years) between January 2006 and June 2015 were included. The demographic and clinical characteristics, laboratory data and imaging parameters were obtained and used to build a BN model to estimate the probability of HBsAg seroclearance. Baseline serum HBsAg and hepatitis Be antigen (HBeAg) levels, virological response and HBeAg seroclearance were the most significant predictors of HBsAg seroclearance. The post-test probability table showed that patients with baseline HBsAg concentrations ≤2000 IU/mL, negative baseline HBeAg, an initial virological response and without HBeAg seroclearance (i.e. no recurrence of HBeAg positivity during follow-up) were most likely to have HBsAg seroclearance. The constructed BN model had an area under the receiver operating characteristic curves of 0.896 (95% confidence interval [CI]: 0.892, 0.899), a sensitivity of 0.840 (95% CI: 0.833, 0.846), a specificity of 0.880 (95% CI: 0.876, 0.884) and an accuracy of 0.878 (95% CI: 0.874, 0.882) for predicting HBsAg seroclearance. The established BN model accurately estimated the probability of HBsAg seroclearance and is a promising tool to assist clinical decision-making.
