Incidence of liver cancer in young adults according to the Global Burden of Disease database 2019. Hepatology 2024:01515467-990000000-00835. [PMID: 38598364 DOI: 10.1097/hep.0000000000000872] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Accepted: 02/19/2024] [Indexed: 04/12/2024]
Abstract
BACKGROUND AND AIMS The worldwide burden of cancer is increasing in younger populations. However, the epidemiology of primary liver cancer remains understudied in young adults compared to other cancer forms. APPROACH AND RESULTS This study analyzed data from the Global Burden of Disease study between 2010 and 2019 to assess the age-standardized incidence, mortality, and disability-adjusted life years associated with primary liver cancer in the young (15-49 y), stratified by region, nation, sociodemographic index, and sex. The study found a global estimate of 78,299 primary liver cancer cases, 60,602 deaths, and 2.90 million disability-adjusted life years in the young population. The Western Pacific region exhibited the highest burden in 2019, showing the most significant increase compared to other regions between 2010 and 2019. More than half of the countries worldwide have undergone an increase in primary liver cancer incidence rates in young adults. Around 12.51% of deaths due to primary liver cancer occur in young individuals. Throughout the study period, there was a significant decline in primary liver cancer mortality due to most etiologies, except for metabolic dysfunction-associated steatotic liver disease-attributable primary liver cancer (annual percentage change + 0.87%, 95% CI: 0.70%-1.05%) and alcohol-attributable primary liver cancer (annual percentage change + 0.21%, 95% CI: 0.01%-0.42%). The limitations of the Global Burden of Disease database include reliance on the quality of primary data and possible underestimation of alcohol consumption. CONCLUSIONS Over the past decade, there has been a marked increase in the burden of primary liver cancer, especially that originating from steatotic liver disease. This trend calls for the development of urgent and comprehensive strategies to mitigate this rising burden globally.

Expression and purification of Hepatitis B virus core antigen using Escherichia coli and its utilization for the diagnosis of Hepatitis B virus infections. Biologicals 2024; 85:101726. [PMID: 37979341 DOI: 10.1016/j.biologicals.2023.101726] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 10/07/2023] [Accepted: 10/31/2023] [Indexed: 11/20/2023] Open
Abstract
Hepatitis B virus (HBV) is responsible for most of the viral hepatitis worldwide. HBV is a partially double stranded DNA virus that is composed of four main open reading frames (ORFs) encoding its important antigens, namely hepatitis B surface antigen (HBsAg), hepatitis B core antigen (HBcAg), HBV polymerase and hepatitis B X antigen (HBxAg). In this study, we report a successful method for the cloning and expression of HBcAg. The ORF of HBcAg was successfully amplified using polymerase chain reaction (PCR), cloned into the expression vector pRSET-B and transformed to Escherichia coli (E. coli) BL-21 (DE3) pLysS strain for protein expression. Successful expression of HBcAg was accomplished, in which an induced protein with a molecular weight of 24 kDa was obtained and confirmed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and Western blotting. The produced HBcAg was successfully used for the diagnosis of HBV infected patient through detection of antibodies against HBcAg (anti-HBcAg) in the serum of the patient utilizing Western blotting. Overall, this study provides a simple, convenient and efficient protocol for the production of HBcAg that can be used as an important candidate to study the diagnosis and prognosis of HBV disease, as well as for understanding the epidemiological prevalence of HBV cases and production of anti-HBcAg.

Front Public Health 2023; 11:1315392. [PMID: 38186703 PMCID: PMC10766842 DOI: 10.3389/fpubh.2023.1315392] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Accepted: 12/11/2023] [Indexed: 01/09/2024] Open
Abstract
Background The global burden of cirrhosis and other chronic liver diseases due to hepatitis B (collectively referred to as hepatitis B-associated cirrhosis in this paper) in children and adolescents must be understood and investigated. Methods Data were extracted from the GBD database, and calculations were performed at global, regional, and national level. We calculate the incidence, prevalence, and disability-adjusted life years (DALYs) and annual average percentage changes (AAPCs). Findings Globally, the prevalent cases of children and adolescents with hepatitis B-associated cirrhosis decreased from 125,053.98 × 10^3 in 1990 to 46,400.33 × 10^3 in 2019. Compared with 1990, the incidence rate of cirrhosis increased in low (95.51%) and low-middle SDI areas (26.47%), whereas it decreased in other SDI areas. The AAPC of incidence has increased in low-middle SDI areas (AAPC 0.12 [95% CI: 0.04-0.20]). At the regional level, the East Asia region has experienced the largest reduction. Conversely, Western Sub-Saharan Africa was the most serious region. Notably, South Asia was the only region where the AAPC of cirrhosis incidence (AAPC 0.77 [95% CI, 0.68-0.86]) increased. Conclusion Globally, the overall burden of hepatitis B-associated cirrhosis in children and adolescents has declined significantly, but the number of cirrhosis incidence cases in low-middle and low-SDI areas has increased. The incidence in South Asia is rising, and the burden on Africa remains serious. Prevention and treatment of hepatitis B-associated cirrhosis in children and adolescents should not be ignored.

Abstract
In recent decades, microRNAs (miRNAs) have emerged as key regulators of gene expression, and the identification of viral miRNAs (v-miRNAs) within some viruses, including hepatitis B virus (HBV), has attracted significant attention. HBV infections often progress to chronic states (CHB) and may induce fibrosis/cirrhosis and hepatocellular carcinoma (HCC). The presence of HBV can dysregulate host miRNA expression, influencing several biological pathways, such as apoptosis, innate and immune response, viral replication, and pathogenesis. Consequently, miRNAs are considered a promising biomarker for diagnostic, prognostic, and treatment response. The dynamics of miRNAs during HBV infection are multifaceted, influenced by host variability and miRNA interactions. Given the ability of miRNAs to target multiple messenger RNA (mRNA), understanding the viral-host (human) interplay is complex but essential to develop novel clinical applications. Therefore, bioinformatics can help to analyze, identify, and interpret a vast amount of miRNA data. This review explores the bioinformatics tools available for viral and host miRNA research. Moreover, we introduce a brief overview focusing on the role of miRNAs during HBV infection. In this way, this review aims to help the selection of the most appropriate bioinformatics tools based on requirements and research goals.

Abstract
OBJECTIVE China concentrates a large part of the global burden of HBV infection, playing a pivotal role in achieving the WHO 2030 global hepatitis elimination target. METHODS We searched for studies reporting HBV surface antigen (HBsAg) seroprevalence in five databases until January 2023. Eligible data were pooled using a generalised linear mixed model with random effects to obtain summary HBsAg seroprevalence. Linear regression was used to estimate annual percentage change (APC) and HBsAg prevalence in 2021. RESULTS 3740 studies, including 231 million subjects, were meta-analysed. HBsAg seroprevalence for the general population decreased from 9.6% (95% CI 8.4 to 10.9%) in 1973-1984 to 3.0% (95% CI 2.1 to 3.9%) in 2021 (APC=-3.77; p<0.0001). Decreases were more pronounced in children <5 years (APC=-7.72; p<0.0001) and 5-18 years (-7.58; p<0.0001), than in people aged 19-59 years (-2.44; p<0.0001), whereas HBsAg seroprevalence increased in persons ≥60 years (2.84; p=0.0007). Significant decreases were observed in all six major Chinese regions, in both men (APC=-3.90; p<0.0001) and women (-1.82; p<0.0001) and in high-risk populations. An estimated 43.3 million (95% uncertainty interval 30.7-55.9) persons remained infected with HBV in China in 2021 (3.0%), with notable heterogeneity by region (<1.5% in North China to>6% in Taiwan and Hong Kong) and age (0.3%, 1.0%, 4.7% and 5.6% for <5 years, 5-18 years, 19-59 years and ≥60 years, respectively). CONCLUSIONS China has experienced remarkable decreases in HBV infection over the last four decades, but variations in HBsAg prevalence persist in subpopulations. Ongoing prevention of HBV transmission is needed to meet HBV elimination targets by 2030. TRIAL REGISTRATION NUMBER PROSPERO (CRD42021284217).

Front Oncol 2023; 13:1192597. [PMID: 37664074 PMCID: PMC10472833 DOI: 10.3389/fonc.2023.1192597] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Accepted: 07/11/2023] [Indexed: 09/05/2023] Open
Abstract
Background Liver cancer (LC) is one of the most common malignancies. Currently, nanotechnology has made great progress in LC research, and many studies on LC nanotechnology have been published. This study aims to discuss the current status, hot spots, and research trends in this field through bibliometric analysis. Methods The Web of Science Core Collection (WoSCC) database was searched for papers related to hepatocellular carcinoma (HCC) included from January 2000 to November 2022, and its research hotspots and trends were visualized and analyzed with the help of VOSviewer. In addition, a search was conducted to find LC papers related to nanotechnology. Then we used the visual analysis software VOSviewer and CiteSpace to evaluate the contributions of countries/regions, authors, and journals related to the topic and analyze keywords to understand the research priorities and hot spots in the field as well as the development direction. Results There are 1908 papers in the highly cited literature on LC, and its research hotspots are pathogenesis, risk factors, and survival rate. The literature on the application of nanotechnology in LC had 921 papers. Among them, China (n=560, 60.8%) and the United States (n=170, 18.5%) were the countries with the highest number of published papers. Wang Yan (n=11) and Llovet JM (n=131) were the first authors and co-cited authors, respectively. The International Journal of Nanomedicine was the most prolific academic journal (n=41). In addition to "hepatocellular carcinoma" and "nanoparticles", the most frequent keyword was "drug delivery". In recent years, "metastasis" and "diagnosis" appeared in the keyword bursts. This indicates that the application of nanoparticles in the early diagnosis and drug delivery of LC (including liver metastasis) has a good prospect. Conclusion Nanotechnology has received more and more attention in the medical field in recent years. As nanoparticles are easily localized in organelles and cells, they can increase drug permeability in tumor tissues, improve drug delivery efficiency and reduce drug toxicity. Our research results were the first scientific evaluation of the application of nanotechnology in LC, providing scholars with research hotspots and development trends.

Abstract
INTRODUCTION Globally, hepatitis B virus (HBV) is a leading cause of liver disease. People who inject drugs (PWID) are at greater risk than the general population of contracting HBV. This risk could depend on societal factors in different countries. We investigated the associations between country-level chronic HBV prevalence in PWID with national indicators of development and prevalence of HIV and hepatitis C virus (HCV). METHODS We used global systematic review data on chronic HBV prevalence (hepatitis B surface antigen-positive) among PWID and country-level sociodemographic characteristics from online databases. National random-effects meta-analysis estimates of HBV prevalence were the outcome in linear regression models testing for associations with country-level characteristics. RESULTS The study included 131,710 PWID from 304 estimates in 55 countries: the pooled HBV prevalence among PWID in the countries analysed was 4.5% (95% CI 3.9-5.1), the highest regional pooled prevalence was in East and Southeast Asia (17.6% [13.3-22.3]), and the lowest was in Western Europe (1.7% [1.4-2.1]). In multivariable models, no indicators of development were associated with HBV prevalence, but there was evidence of positive associations between HBV prevalence in the general population and among PWID, and evidence of HIV and HCV prevalence in PWID being associated with HBV prevalence in PWID: multivariable coefficients 0.03 (95% CI 0.01-0.04); p < 0.001, and 0.01 (95% CI 0.00-0.03); p = 0.01, respectively. DISCUSSION AND CONCLUSIONS HBV prevalence among PWID was associated with HIV and HCV prevalence among PWID and background HBV prevalence in the general population, highlighting the need for improving harm reduction in PWID and implementation of HBV vaccination, especially where HBV is endemic.

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

Abstract
BACKGROUND AND AIMS Data are needed to inform hepatitis B virus (HBV) testing and treatment policies in Ghana to make progress towards achieving the 2030 WHO elimination targets. This study investigated testing patterns for HBV and described the age, sex, and region-specific prevalence of HBV infection in Ghana using hospital data. METHODS A nationwide multi-centre cross-sectional study was performed where hospital-based registers were reviewed. These included review of 139,966 laboratory, 169,048 blood bank, and 83,920 delivery register entries from 22 healthcare institutions in Ghana. Frequencies and proportions, and crude and pooled estimates reported. Chi squared test was used for tests of independence. Logistic regression was used to identify factors associated with a positive test result. RESULTS The crude HBsAg seroprevalence was 8.48% (95%CI 8.25-8.57%) with pooled estimate of 11.40% (95%CI 10.44-12.35). HBsAg seroprevalence among children under 5 years was 1.87% (95%CI 1.07-3.27) and highest age-specific seroprevalence was in those 40-49 years. The highest region-specific seroprevalences was in the Savannah (22.7%). Predictors of a positive HBsAg RDT test included female sex (OR 0.81 95% CI 0.74-0.88), and age (OR 1.005 95%CI 1.002-1.007). The proportion of parturient women receiving HBsAg testing increased between 2017 (87.2%) and 2020 (94.3%) (p < 0.001). The crude HBsAg seroprevalence in parturient women was 6.14% (95% CI 5.97-6.31). Among blood donors the crude HBsAg seroprevalence was 5.69% (95%CI 5.58-5.80). Data from 2 teaching hospitals indicated that in 2020, although 1500 HBsAg positive tests were recorded only 746 serological profile and 804 HBV DNA tests were performed. HBV e antigen seroprevalence was 6.28% (95%CI 4.73-7.84). CONCLUSION AND RECOMMENDATIONS Ghana remains a country with high HBV burden. There is an unequal distribution, with higher HBsAg seroprevalence in the north of the country. Furthermore, PCR testing is not widely available outside of large teaching hospitals, which limits diagnostic work-up. Hepatitis reporting systems and registers should be improved to facilitate data capture of indicators and standardised across the country to allow for comparability. Furthermore, where gains have been made in testing among pregnant women, there is a need for linkage to appropriate care.

Abstract
BACKGROUND AND PURPOSE Hepatitis B virus (HBV) infection causes both acute and chronic liver disease, performing the key driver toward the global elimination of viral hepatitis by 2030. We used data from Global Burden of Disease (GBD) study to quantify the burden of liver disease due to hepatitis B at the global, regional and national levels. METHODS Annual incident cases and age-standardized incidence rates (ASIRs) of liver disease due to hepatitis B between 1990 and 2019 were collected from GBD study 2019. Percentage changes of incident cases and estimated annual percentage changes (EAPCs) of ASIRs were calculated to quantify their temporal trends. Correlations between EAPC and socio-demographic index (SDI) and universal health coverage index (UHCI) were evaluated by Pearson correlation analyses. RESULTS Globally, the incident cases of liver disease due to hepatitis B decreased by 4.51% from 84.45 million in 1990 to 80.65 million in 2019 and ASIR decreased by an average of 1.52% (95%CI - 1.66%, - 1.37%) per year in this period. For the spectrum of liver disease due to hepatitis B, ASIR of cirrhosis and other chronic liver diseases increased by an average of 0.13% (95%CI 0.04%, 0.22%) per year in low SDI region and 0.24% (95%CI 0.04%, 0.34%) per year in low-middle SDI region, and ASIR of liver cancer increased by an average of 0.91% (95%CI 0.37%, 1.46%) per year in high SDI region in 1990-2019. Positive correlations of EAPC in ASIR of liver cancer with SDI and UHCI were observed in nations with SDI ≥ 0.7 or UHCI ≥ 70. CONCLUSION HBV infection remains a global health problem, causing low and low-middle SDI regions with an increasing trend of cirrhosis and other chronic liver diseases, and high SDI region with an increasing trend of liver cancer. Efforts to eliminate hepatitis B by 2030 needs to focus on not only developing regions but also developed regions.

Abstract
Among HBV-infected persons, there is a group of people with hepatitis B surface antigen (HBsAg) showing persistently low levels of expression. The production of low-level HBsAg does not mean a good outcome of chronic HBV infection. Patients still have virus replication and sustained liver damage, and they have the potential to transmit the infection. This risk poses a challenge to clinical diagnosis and blood transfusion safety and is a major concern of experts. However, the mechanism behind persistent low-level HBsAg expression in serum is not completely clear, and complete virus clearance by the host is vital. In this review, we summarize the research progress on the mechanism behind low-level expression of HBsAg in patients with chronic HBV infection in recent years.

Abstract
Point-of-care (POC) testing for nucleic acid that combines pretreatment and molecular diagnosis is crucial in analyzing complex samples such as those encountered in clinical diagnosis. Herein, we developed a centrifugal microfluidic platform, which can achieve a series of functions including separating serum and adsorbing, washing, eluting, and detecting DNA. We combined multiple signal enhancement systems including recombinase polymerase amplification (RPA), T7 transcription technology, and clustered regularly interspaced short palindromic repeat (CRISPR) technology to yield an ultrabright signal, which can avoid false-negative results. As an application, hepatitis B virus (HBV), a virus that causes global public health problems, was successfully detected and genotyped from whole blood on the automated centrifugal microfluidic platform. Compared to the traditional diagnosis process, the POC platform largely decreased the consumption of time from 3 to 1 h and the consumption of professional labor from three persons to only one. The automated centrifugal microfluidic platform integrated pretreatment and molecular diagnosis will play an essential role in clinical detection.

Against All Odds? Addiction History Associated with Better Viral Hepatitis Care: A Dutch Nationwide Claims Data Study. J Clin Med 2022; 11:jcm11041146.

Abstract
The elimination of viral hepatitis in target populations is crucial in reaching WHO viral hepatitis elimination goals. Several barriers for the treatment of viral hepatitis in people with addictive disorders have been identified, yet nationwide data on hepatitis healthcare utilization (HCU) in these patients are limited. We investigated whether a history of addictive disorder is associated with suboptimal hepatitis HCU, indicating failure to receive diagnostic care or treatment. We identified all newly referred viral hepatitis patients in the Netherlands between 2014 and 2019 by query of the Dutch national hospital claims database. Each patient’s first year of HBV or HCV care activities was collected and clustered in two categories, ‘optimal’ or ‘suboptimal’ hepatitis HCU. Optimal HCU includes antiviral therapy. We tested the association between addiction history and HCU, adjusted for sex, age, migrant status, and comorbidity. In secondary analyses, we explored additional factors affecting hepatitis HCU. We included 10,513 incident HBV and HCV patients, with 13% having an addiction history. Only 47% of all patients achieved optimal hepatitis HCU. Addiction history was associated with less suboptimal HCU (adjusted OR = 0.73, 95% CI = 0.64–0.82). Migration background was associated with suboptimal HCU (OR = 1.62, 95% CI = 1.50–1.76). This study shows that addiction history is associated with higher viral hepatitis HCU; thus, this population performs better compared to non-addicted patients. However, less than 50% of all patients received optimal hepatitis care. This study highlights the need to improve hepatitis HCU in all patients, with a focus on migrant populations. Linkage to care in the addicted patients is not studied here and may be a remaining obstacle to be studied and improved to reach WHO viral hepatitis elimination goals.

Abstract
INTRODUCTION AND OBJECTIVES Viral hepatitis is a global health problem with unequal distribution of disease burden in which low-income people are at higher risk for acquisition and underlying liver diseases. This study aimed to seek the prevalence of hepatitis B and C viruses, HIV, and liver damage among low-income patients attending a public tertiary care hospital in West Mexico. METHODS A retrospective/cross-sectional study at the Department of Genomic Medicine in Hepatology was conducted between March 1, 2016 to March 30, 2017. A total of 10,352 patients tested for anti-HCV, HBsAg, or anti-HIV (n=23,074) were included. Age, gender, and hospital service were registered. Liver fibrosis was assessed using APRI and FIB-4 scores. RESULTS Overall, 3.9% were anti-HCV+ (305/7848), 1.0% were HBsAg+ (80/7894), and 2.9% were anti-HIV+ (210/7332). A 43.8% (750/1959) of patients negative for all viruses had either abnormal AST, ALT, or GGT (≥40 UI/L). Also, significant liver fibrosis (APRI ≥ 0.7) was prevalent in 10.6% (191/1804). In patients who tested positive for viral infections, liver fibrosis was detected in 20.4% (11/54) of HBsAg+, 34.2% (53/155) in anti-HCV+ and 15.5% (16/103) in anti-HIV+. Anti-HCV+ was highest in Geriatrics (11.1%), HBsAg+ in HIV patients (3.0%) and anti-HIV+ in Emergency room attendees (33.3%). CONCLUSION High seroprevalence of HCV, HBV, and HIV infections was found among the studied population. Significant liver fibrosis was detected in negative and positive patients for viral infections. Medical services need to continuously test for viral infections, promote early detection of chronic liver damage and identify target patients for elimination strategies to decrease disease burden.

Abstract
Background: Hepatitis B surface antigen (HBsAg) is widely used in hepatitis B screening, and HBsAg seroclearance indicates hepatitis B eradication. Few studies have explored the incidence of and determinants for spontaneous seroclearance using a long-term follow-up cohort study. Our research aimed to examine the incidence of and influencing factors for hepatitis B virus infection and spontaneous clearance of HBsAg from a large-scale cohort in China. Methods: A total of 151,926 resident individuals in Tongxiang underwent HBsAg screening at least thrice in a 7-year period. Serum samples collected at baseline and follow-up examinations were tested for HBsAg. Cox proportional hazard models were used to analyze determinants of HBsAg seroclearance and persistent HBsAg presence. Results: Among the 151,926 participants, new hepatitis B infections occurred in 4,497 participants, yielding an incidence rate of 571.38 per 100,000 person-years. The incidence rate for males was higher than that for females. In the multivariate Cox regression analysis, female gender, alcohol drinking history, hepatitis family history and middle-age group were predictors for persistent positive HBsAg status. Conclusions: The incidence rate of new hepatitis B infections was 571.38 per 100,000 person-years. Male and aged people in this community cohort have a higher infection rate. Alcohol drinking and hepatitis family history were risk factor leading to chronic infection. Female and middle-aged people were prone to persistent positive HBsAg status.

Abstract
BACKGROUND Human immunodeficiency virus (HIV)/AIDS and tuberculosis (TB) continue to be a significant global burden, disproportionately affecting low- and middle-income countries (LMICs). While much progress has been made in treating these epidemics, this has led to a rise in liver complications, as patients on ARTs and anti-TBs are at an increased risk of drug-induced liver injury (DILI). Therefore, patients on these medicines require consistent screening of liver function. Due to logistical barriers, gold standard DILI screening fails to be executed at the point-of-care in LMICs. For this reason, we used cost-effectiveness analysis to gauge the efficacy of a paper-test that could be implemented in these settings. METHODS We used a Markov Model to simulate HIV and TB coinfected patient care in LMICs using both publicly available data and data from Village Health Works in Burundi. We compared the cost-effectiveness of two screening interventions for liver function monitoring: 1. paper-based point-of-care testing, and 2. gold-standard laboratory testing. These interventions were compared against baseline clinical monitoring. RESULTS The paper test showed a 56% increase in efficacy over clinical monitoring alone. The paper-test is more cost-effective than the gold-standard method, at a ceiling cost of $1.60 per test. CONCLUSIONS With this information, policy makers can be informed as to the large potential value of paper-based tests when gold standard monitoring is not achievable. Scientists and engineers should also keep these analyses in mind and while in development limit the cost of an ALT screening test to $1.60.

Abstract
Utilizing kidneys from donors with hepatitis B is one way to alleviate the current organ shortage situation. However, the risk of hepatitis B virus (HBV) transmission remains a challenge that undermines the chance of organs being used. This is particularly true with hepatitis B surface antigen (HBsAg) positive donors despite the comparable long-term outcomes when compared with standard donors. To reduce the risk of HBV transmission, a comprehensive approach is needed. This includes assessment of donor risk, optimal allocation to the proper recipient, appropriate immunosuppressive regimen, optimizing the prophylactic therapy, and post-transplant monitoring. This review provides an overview of current evidence of kidney transplants from donors with HBsAg positivity and outlines the challenge of this treatment. The topics include donor risk assessment by adopting the nucleic acid test coupled with HBV DNA as the HBV screening, optimal recipient selection, importance of hepatitis B immunity, role of nucleos(t)ide analogues, and hepatitis B immunoglobulin. A summary of reported long-term outcomes after kidney transplantation and proposed criteria to utilize kidneys from this group of donors was also defined and discussed.

Abstract
As we strive towards the WHO goal of elimination of viral hepatitis as a public health threat by 2030, implementation of reliable, accurate diagnostic assays is crucial to identify those at risk of disease progression and those at risk of transmission. Ironically those at greatest risk of chronic hepatitis B are often in resource-poor regions with limited access to testing, collection, storage, and/or transportation of peripheral blood. The Xpert® HBV Viral Load assay provides an easy to use, convenient means of measuring load on GeneXpert platforms. In this study, the Xpert assay is evaluated against four commercially available high-throughput assays for Hepatitis B virus (HBV) loads. In addition application of dried blood spots (DBS) for estimation of viral load is assessed on real-world samples collected from a remote Pacific Island, Kiribati. A total of 107 serum/plasma samples were tested in the Xpert HBV load assay and compared with the Abbott m2000, Alinity m, and Roche Cobas CAP/CTM and 6800. Fifty-three DBS were tested in the Xpert assay and compared with matching serum samples. Overall 82% serum/plasma samples demonstrated good correlation between the Xpert and Roche and Abbott assays, to within 0.5 log10 IU/ml. The greatest discrepancies were seen at the limits of quantification of all assays. About 85.4% DBS gave estimable viral loads to within 1 log10 IU/ml of the serum load. The Xpert HBV viral load assay is recommended for all settings but particularly useful for resource-poor settings. Utility of DBS with the Xpert assay provides a simple means for testing in remote settings.

Abstract
Viral hepatitis represents a major public health hazard and is associated with significant global mortality. Over the last decade, there have been significant developments in the prevention and treatment of viral hepatitis. These changes have led to a situation whereby global elimination has become a realistic goal, fully endorsed by the World Health Organization (WHO). By 2030, the WHO aims to reduce viral hepatitis mortality by 65% and reduce new infections by 90% by 2030. These are ambitious targets and will only be met through a sustained programme. This will require expertise from hepatologists and virologists and the fields of public health and primary care. In this article, we review the causes of viral hepatitis, its management through prevention and treatments, and the most pressing challenges and recent advances.

Implications of Birth-Dose Vaccination against Hepatitis B Virus in Southeast Asia. Vaccines (Basel) 2021; 9:vaccines9040374. [PMID: 33921259 PMCID: PMC8069988 DOI: 10.3390/vaccines9040374] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2021] [Revised: 04/09/2021] [Accepted: 04/10/2021] [Indexed: 02/07/2023] Open
Abstract
The World Health Organization (WHO) South-East Asia Regional Office (SEARO) covers 11 countries with a combined population of about 2 billion people, making it the most populous of the six WHO regions. In 1992, the WHO advocated including the hepatitis B vaccine in the Expanded Program of Immunization (EPI) and vaccinating all infants and children three times within 1 year of birth (HepB3). Recently, the WHO advocate birth-dose hepatitis B vaccination (HepB-BD) as soon as possible after birth, preferably within 24 hours. In 2016, the SEARO endorsed a regional hepatitis B control goal with a target of hepatitis B surface antigen (HBsAg) seroprevalence of ≤1% among children aged ≥5 years by 2020. Of the 11 SEARO countries, four achieved this target on schedule. Out of these four countries, two countries (Bangladesh and Nepal) have not adopted HepB-BD in EPI program. On the other hand, the coverage of HepB3 is not satisfactory in some SEARO countries, including India which adopted HepB-BD but could not achieve the overall target of SEARO. Thus, it is a point of debate whether emphasis should be placed on proper implementation of HepB3 or whether a new agenda of HepB-BD should be incorporated in developing countries of SEARO. The article discusses strengthening and expanding the Hepatitis B vaccination program in SEARO countries with an emphasis on HepB and HepB-BD programs.

Wang R, Liu C, Chen T, Wang Y, Fan C, Lu L, Lu F, Qu C. Neonatal hepatitis B vaccination protects mature adults from occult virus infection. Hepatol Int 2021; 15:328-337. [PMID: 33751394 DOI: 10.1007/s12072-021-10156-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Accepted: 02/11/2021] [Indexed: 12/18/2022]
Abstract
BACKGROUND Among elder children/young adults who received hepatitis B virus (HBV) vaccination during infancy, the serological status of HBsAg-negative and anti-HBc-positive [HBsAg(-)/anti-HBc(+)] was frequently reported, indicating potential occult HBV infection (OBI). It is required to define the long-term protection of neonatal vaccination against OBI in their mature adulthood. METHODS Building upon the 1983-1990 established Qidong Hepatitis B Intervention Study, we sampled 10% of the 28-35-year-old participants, who remained in the cohort by 2012. Each participant was tested for serological markers of HBsAg, anti-HBs, HBeAg, anti-HBe and anti-HBc. HBV-DNA and relaxed circular DNA (rcDNA) were determined in some HBsAg(-)/anti-HBc(+) individuals. RESULTS Totally, 3615 individuals from the neonatal vaccination group and 3100 individuals from the control group donated blood samples, respectively. In the vaccination group, the prevalence of HBsAg was 1.58% (57/3615), HBsAg(-)/anti-HBc(+) was 4.70% (170/3615), significantly lower than in the control group, which was 7.45% (231/3100) and 19.48% (640/3100) respectively (all p < 0.001). With aging, HBsAg(-)/anti-HBc(+) prevalence increased in the sampled participants from the control group (pfor trend < 0.001), but uncertain from the vaccination group. Of HBsAg(-)/anti-HBc(+), HBV-DNA was detected in 13.08% (17/130) from the vaccination group, and in 4.18% (12/287) from the control group. HBV rcDNA was detected in most sera that were tested positive for HBV-DNA. CONCLUSIONS OBI occurred in some vaccinated adults. However, neonatal HBV vaccination kept the effective protection against OBI in mature adults.

Abstract
Dried blood spots (DBS) have been proposed as an alternative diagnostic technique for chronic viral hepatitis. The aim of this observational study was to correlate serologic HBV, HCV, and HDV status and reflex the respective viral load testing by PSC-DBS samples from capillary blood vs conventional plasma samples in patients with chronic viral hepatitis. Besides, we apply these tests in a prospective study for chronic viral hepatitis diagnosis in a rural region of sub-Saharan Africa. In total, 124 HBsAg-positive patients, 75 anti-HCV positive, 2 with HBV-HCV coinfection, and 13 anti-HDV positive were included. PSC-DBS sensitivity/specificity was 98.4 %/96.2 % for HBsAg detection, 98.7 %/100 % for anti-HCV, and 84.6 %/100 % for anti-HDV. HCV-RNA was quantified in all viremic patients using DBS. Only 42 of 78 (53.8 %) samples with HBV-DNA viremia were quantifiable by DBS. Sensitivity increased to 95.7 % in patients with HBV-DNA levels >2000 IU/mL. There was a high correlation between DBS and venous blood. The prevalence of HBsAg among the 93 individuals tested in Angola was 11 %, and 60 % of cases had detectable HBV-DNA viremia. As a conclusion, PSC-DBS is useful for chronic viral hepatitis screening and reflex molecular diagnosis showing globally high sensitivities and correlation with conventional blood samples.

Abstract
Hepatocellular carcinoma (HCC) remains the fourth leading cause of cancer-related death worldwide. However, the clinical diagnosis and treatment modalities are still relatively limited, which urgently require the development of new effective technologies. Recently, nanotechnology has gained extensive attention in HCC surveillance, imaging and pathological diagnosis, and therapeutic strategies. Typically, nanomedicines have been focused on early HCC diagnosis and precise treatment of advanced HCC, which has developed and improved a variety of new technologies and agents for future clinical practice. Furthermore, strategies of facilitating drug release and delivery in current treatment processes such as ablation, systematic therapy, transcatheter arterial chemoembolization, molecular targeted therapy, and immune-modulating therapy have also been studied widely. This review summarizes the recent advances in this area according to current clinical HCC guidelines: 1) Nanoparticle-based HCC surveillance; 2) Nanotechnology for HCC diagnosis; 3) Therapeutic advances for HCC Management; 4) Limitations of applications in nanotechnology for HCC; 5) Conclusions and perspectives. Although there are still many limitations and difficulties to overcome, the investigations of nanomedicines are believed to show potential applications in clinical practice.

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
Hepatitis B virus (HBV) genotype E (HBV-E) accounts for the majority of chronic hepatitis B (CHB) infections in West Africa. We aimed to determine factors associated with HBV-E-induced hepatocellular carcinoma (HCC) in West Africa. Data on patients from Burkina Faso who were hepatitis B surface antigen positive (HBsAg+) and had CHB were analyzed. HBV viral load and hepatitis B e antigen (HBeAg) status were measured in 3,885 individuals with CHB without HCC (CHB HCC-) and 59 individuals with CHB with HCC (CHB HCC+). HBV genotyping was performed for 364 subjects with CHB HCC- and 41 subjects with CHB HCC+. Overall, 2.5% of the CHB HCC- group was HBeAg+ compared with 0% of the CHB HCC+ group. Of the 364 patients who were CHB HCC- with available genotyping, the frequencies of HBV genotypes E and C/E were 70.3% and 12.9%, respectively. Age (odds ratio [OR] for older age, 1.08; 95% confidence interval [CI], 1.06-1.10 per 1-year increase in age), male sex (OR, 2.03; 95% CI, 1.11-3.69), and HBV viremia (OR, 1.48; 95% CI, 1.31-1.67 per 1 log10 IU/mL) were each associated with HCC diagnosis. Patients with genotype E had a lower HBeAg prevalence (6.3% vs. 14.9%), lower HBV viral load, and higher prevalence of cirrhosis (14.5% vs. 4.8%) than patients with genotype C/E. Conclusion: HBV-E is the most common circulating strain (70.3%) in West African patients. HCC was associated with older age, male sex, and high HBV viral load. It is expected that these results will further inform guidance on clinical management of HBV infection in West Africa.

Upconverting nanoparticle reporter-based highly sensitive rapid lateral flow immunoassay for hepatitis B virus surface antigen. Anal Bioanal Chem 2020; 413:967-978. [PMID: 33230700 PMCID: PMC7813740 DOI: 10.1007/s00216-020-03055-z] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2020] [Revised: 10/22/2020] [Accepted: 11/09/2020] [Indexed: 01/22/2023]
Abstract
Detection of hepatitis B Virus surface antigen (HBsAg) is an established method for diagnosing both acute and chronic hepatitis B virus (HBV) infection. In addition to enzyme immunoassays (EIAs), rapid diagnostic tests (RDTs) are available for the detection of HBsAg in resource-poor settings. However, the available RDTs have inadequate sensitivity and therefore are not suitable for diagnosis of patients with low levels of HBsAg and for blood screening. To provide a high-sensitivity RDT, we developed a lateral flow immunoassay (LFIA) for HBsAg utilizing upconverting nanoparticle (UCNP) reporter. The UCNP-LFIA can use whole blood, serum, or plasma and the results can be read in 30 min using a reader device. When compared with a commercial conventional visually read LFIA, the developed UCNP-LFIA had a Limit of Detection (LoD) of 0.1 IU HBsAg/ml in spiked serum, whereas the LoD of the conventional LFIA was 3.2 IU HBsAg/ml. The developed UCNP-LFIA fulfills the WHO criterion for blood screening (LoD ≤ 0.13 IU HBsAg/ml) in terms of LoD. The UCNP-LFIA and conventional LFIA were evaluated with well-characterized sample panels. The UCNP-LFIA detected 20/24 HBsAg-positive samples within the HBsAg Performance Panel and 8/10 samples within the Mixed Titer Performance Panel, whereas the conventional LFIA detected 8/24 and 4/10 samples in these panels, respectively. The performance of the assays was further evaluated with HBsAg-positive (n = 108) and HBsAg-negative (n = 315) patient samples. In comparison with a central laboratory test, UCNP-LFIA showed 95.4% (95% CI: 89.5–98.5%) sensitivity whereas sensitivity of the conventional LFIA was 87.7% (95%CI: 79.9–93.3%).

[PMID: 32889395 PMCID: PMC7443316 DOI: 10.1016/j.bios.2020.112513] [Citation(s) in RCA: 70] [Impact Index Per Article: 17.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 07/30/2020] [Accepted: 08/11/2020] [Indexed: 12/18/2022]
Abstract
Infectious diseases are the ever-present threats to public health and the global economy. Accurate and timely diagnosis is crucial to impede the progression of a disease and break the chain of transmission. Conventional diagnostic techniques are typically time-consuming and costly, making them inefficient for early diagnosis of infections and inconvenient for use at the point of care. Developments of sensitive, rapid, and affordable diagnostic methods are necessary to improve the clinical management of infectious diseases. Quartz crystal microbalance (QCM) systems have emerged as a robust biosensing platform due to their label-free mechanism, which allows the detection and quantification of a wide range of biomolecules. The high sensitivity and short detection time offered by QCM-based biosensors are attractive for the early detection of infections and the routine monitoring of disease progression. Herein, the strategies employed in QCM-based biosensors for the detection of infectious diseases are extensively reviewed, with a focus on prevalent diseases for which improved diagnostic techniques are in high demand. The challenges to the clinical application of QCM-based biosensors are highlighted, along with an outline of the future scope of research in QCM-based diagnostics.

Association between liver fibrosis and appendicular skeletal muscle mass during antiviral therapy in chronic hepatitis B. Dig Liver Dis 2020; 52:1338-1345. [PMID: 32771386 DOI: 10.1016/j.dld.2020.07.004] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2020] [Revised: 06/08/2020] [Accepted: 07/02/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS Sarcopenia is associated with fibrotic burden in patients with chronic hepatitis B. We investigated the dynamic association between fibrosis changes and appendicular skeletal muscle mass during antiviral therapy in patients with chronic hepatitis B. METHODS Between 2015 and 2018, chronic hepatitis B patients who received paired transient elastography to assess fibrotic burden in the liver and bioelectrical impedance analysis to assess appendicular skeletal muscle mass were recruited retrospectively. The sarcopenia index was calculated as total appendicular skeletal muscle mass/body mass index. Significant liver fibrosis was defined as a liver stiffness value≥8 kPa. RESULTS In total, 223 (53.7%) received antiviral therapy, whereas 192 (46.3%) did not. Appendicular skeletal muscle mass decreased significantly in the antiviral therapy group (mean 21.16→21.00 kg, P = 0.01), but not in the non-antiviral therapy group (mean 20.77→20.64 kg, P = 0.134). In a subgroup with significant liver fibrosis, similar findings were observed (mean 20.73→20.54 kg in antiviral therapy group, P = 0.037; mean 21.39→21.07 kg in the non-antiviral therapy group, P = 0.097). Older age, male gender, higher body mass index, and higher aspartate aminotransferase were significantly associated with the increased risk of appendicular skeletal muscle mass reduction (≥5% from the baseline). CONCLUSIONS Appendicular skeletal muscle mass significantly decreased during antiviral therapy in patients with chronic hepatitis B patients.

Abstract
Advanced hepatitis B virus (HBV)-related hepatocellular carcinoma HCC with poor prognosis is often associated with chronic inflammation, immune tolerance, and marked heterogeneity. The interleukin-6 (IL-6)/JAK/STAT3 signal pathways play multiple regulatory roles in modulating inflammation and immunity in cancers. Polarization of myeloid-derived suppressor cells (MDSCs) is involved in HBV-related immunosuppression and CD8+ T-cell activation through ERK/IL-6/STAT3. Icaritin is a small molecule that has displayed anticancer activities through IL-6/JAK/STAT3 pathways in tumor cells and immune cells including CD8+ T cells, MDSCs, neutrophils, and macrophages. This study aimed to confirm icaritin immunomodulation in advanced HBV-related HCC patients with poor prognosis. Immunomodulation of MDSCs was evaluated in BALB/c mice in vivo. Immunomodulation of serum cytokines and a panel of immune checkpoint proteins were assessed in HBV-related, histologically confirmed HCC patients. Poor prognostic characteristics included HBV infection, bulky tumors, Child-Pugh B classification, and metastasis. Clinical end-points included safety, tumor response, and overall survival (OS). Icaritin treatment-induced dynamics of serum cytokines IL-6, IL-8, IL-10, and tumor necrosis factor-α, and soluble immune checkpoint proteins TIM3, LAG3, CD28, CD80, and CTLA-4 were assessed. No grade III/IV treatment-related adverse events were observed. Time-to-progression was significantly associated with the prognostic factors. Improved survival was observed in the advanced HCC patients with dynamic changes of cytokines, immune checkpoint proteins, and immune cells. Median OS (329-565 days) was significantly correlated with baseline hepatitis B surface antigen positivity, cytokines, tumor neoantigens, and Stenotrophomonas maltophilia infection. Composite biomarker scores of high-level α-fetoprotein and T helper type I (Th1)/Th2 cytokines associated with favorable survival warrant further clinical development of icaritin as an alternative immune-modulatory regimen to treat advanced HCC patients with poor prognosis.

Abstract
BACKGROUND Occult hepatitis B virus (HBV) - characterized by the absence of detectable HBsAg in the presence of HBV DNA - represents a potential threat for blood safety. OBJECTIVES This study was conducted with the aim to investigate the serological and molecular characterization of occult HBV infection (OBI) among blood donors in Mozambique. METHODS 1,502 blood donors were tested for HBsAg. All HBsAg-negative individuals were tested for HBV DNA. Antibodies against HBV core, surface and HBe antigen (anti-HBc, anti-HBs, HBeAg) were measured in HBV DNA positive individuals. FINDINGS 1435 serum samples were HBsAg negative and 16 positive for HBV DNA, 14 confirmed to have OBI, corresponding to a frequency of 0.98%. Of the 14 OBI infections identified, 13/14 (92.8%) were positive for anti-HBc, 4/14 (28.5%) for anti-HBs, and no samples were reactive for HBeAg. Of the 14 OBI cases, nine samples (64.2%) were sequenced for the S/P region. Eight samples (88.9%) belonged to genotype A1 and one (11.1%) to genotype E. One escape mutation (T123A) associated with OBI and various amino acid substitutions for genotype A1 and E were observed. MAIN CONCLUSIONS Our results show the importance of using nucleic acid amplification test to detect occult hepatitis B infection in blood donors in Mozambique.

Lancet Gastroenterol Hepatol 2020; 4:315-323.

Abstract
People from low-to-middle income countries have been migrating to western Europe on a large scale in recent years. Data indicate that the number of first-time asylum applications by non-EU members increased from 290 000 in 2011 to more than 1·3 million in 2015. During the peak period of migration, The Global Health Sector Strategy on Viral Hepatitis was adopted by WHO. Viral hepatitis, and particularly hepatitis B virus (HBV), is an important disease because of its high prevalence and associated mortality. In some cases, HBV can be carried by refugees arriving from regions of high and intermediate prevalence. Refugees with HBV might not show clinical symptoms and not be diagnosed in destination countries with a low prevalence, where screening is not regularly done. Although transmission to the host population is low, dedicated surveillance and tailored public health policies are required. It is important to note that some of the countries that receive many migrants do not have a universal HBV vaccination programme. In this Viewpoint, we argue that the current large-scale movement from regions with high or intermediate HBV prevalence should be taken as an opportunity to achieve viral hepatitis elimination targets, by establishing a well prepared infrastructure for HBV screening, vaccination, and treatment.

Abstract
INTRODUCTION Sarcopenia refers to a progressive and generalized muscle mass and strength loss. In liver diseases, it has been related to worse outcomes and high risk of decompensations. AREAS COVERED Sarcopenia is caused by a set of cellular processes in the muscle such as denervation, mitochondrial dysfunction, endotoxemia and inflammation; which are manifested through the alteration of several proteolytic pathways such as lysosomal, proteasomal and caspase systems. In autophagy, myostatin and oxidative stress; such as hyperammonemia, contributes importantly to liver sarcopenia through loss of muscle mass already demonstrated in in vitro and in vivo models. In addition, hormones and the regulation of the intestinal microbiota, influence in a not less important magnitude. In the clinical setting, early identification of sarcopenia has been established as a mandatory item to prevent progression of muscle mass loss; however, diagnostic methods have extreme variation according to methodology, population, etiology and severity of liver disease. Reversing sarcopenia should be an integral therapeutic strategy. EXPERT OPINION Clinical and nutritional interventions should be adapted to liver injury etiology and stage of disease, each of them shares a similar sarcopenia development pathway. There are specific biomarkers that condition or exacerbate loss of skeletal muscle.

Abstract
The albumin-bilirubin (ALBI) score was originally established to stratify prognosis in patients with cirrhosis. The diagnostic accuracy of ALBI score in liver fibrosis staging in patients with chronic hepatitis B remains to be investigated. The present retrospective study, therefore, aimed to evaluate the ability of this score to stage liver fibrosis in these patients. Briefly, consecutive patients with hepatitis B virus (HBV) infection who underwent liver biopsy examinations in Kagawa University Hospital were enrolled. Liver fibrosis stage was assessed using a modified Meta-Analysis of Histological Data in Viral Hepatitis score. Albumin-bilirubin scores were calculated according to the following equation: (log10 total bilirubin [T-Bil] × 0.66) + (albumin [Alb] × -0.085). A total of 91 patients were enrolled in this study. Albumin-bilirubin score was able to differentiate stage 4 from stage 3 fibrosis (P < 0.05). When an ALBI score of -2.190 was adopted as the cutoff value for differentiating stage 4 from stages 1-3, the sensitivity, specificity, and positive likelihood ratio were 85.7%, 74.0%, and 3.300, respectively. Kaplan-Meier analysis showed that baseline ALBI scores < -2.190 correlated with better hepatocellular carcinoma (HCC)-free survival (P < 0.05). In conclusion, ALBI score can be used for liver fibrosis staging in Japanese chronic hepatitis B patients and can help distinguish cirrhotic from non-cirrhotic status. Furthermore, ALBI score was useful as a prognosis biomarker in our patients, with smaller ALBI scores predicting better HCC-free survival. Because calculating ALBI score is easy using serum T-Bil and Alb alone, ALBI score will help clinicians with decision-making in management of HBV-infected patients.

Abstract
The high prevalence of hepatitis B virus (HBV) infection and intracranial atherosclerotic stenosis (ICAS) in Asia raises the question as to whether HBV infection is associated with ICAS. To answer this question, we tested the association between HBV infection and ICAS. Totally, 3072 in-hospital subjects were retrospectively enrolled. All subjects underwent computed tomography angiography (CTA) and serological testing for HBV infection. Based on the results of CTA, all subjects were categorized into 4 groups including ICAS, extracranial atherosclerotic stenosis (ECAS), ICAS/ECAS (both ICAS and ECAS), and normal. HBV infection was divided into 4 patterns including hepatitis B core antibody (anti-HBc) positive/hepatitis B surface antigen (HBsAg) positive, anti-HBc-positive/HBsAg-negative, anti-HBc-negative/HBsAg-positive, and anti-HBc-negative/HBsAg-negative. Risk factors for atherosclerosis were collected based on medical records. Multiple logistic regression models were used to determine the association between infection patterns and ICAS. We found that the anti-HBc-positive / HBsAg-negative pattern was associated with the increased risk of ICAS (OR = 1.462) and not associated with ECAS or ICAS / ECAS. The HBc-positive/HBsAg-positive pattern was not associated with ICAS, ECAS or ICAS/ECAS. In conclusions, the anti-HBc-positive/HBsAg-negative pattern was associated with the increased risk of ICAS. Anti-HBc should be employed to investigate the association between HBV infection and cerebrovascular diseases.

Abstract
BACKGROUND In Cameroon, the prevention of hepatitis B virus (HBV) transmission by blood transfusion is still only based on hepatitis B surface antigen (HBsAg) screening. However, occult HBV infection (OBI) characterised by the absence of detectable HBsAg and low level of viral DNA remains a potential threat for blood safety. The prevalence of OBI was investigated in blood donors from Yaoundé to provide evidence-based recommendations to improve HBV blood safety. MATERIAL AND METHODS Blood donations from August 1st, 2016 to March 31st, 2017 were routinely screened for HBV, human immunodeficiency virus (HIV), and hepatitis C virus (HCV) infections (Murex HBsAg Version 3, Murex HIV Ag/Ab Combination, and Murex HCV Ag/Ab Combination [DiaSorin]). Additional HBV investigations were performed, including hepatitis B core antibody ([HBc] Monolisa Anti-HBc PLUS; BIO-RAD) and HBV DNA tested in minipools of two samples using the quantitative Cobas Taqman HBV assay (Roche; LoQ: 6 IU/mL) and HBV DNA genotyping by sequencing. RESULTS Of 1,162 donations analysed, 91 (7.8%) were reactive for HBsAg. All of them were also anti-HBc positive. Among the 1,071 HBsAg negative samples, 522 (48.7%) were reactive for anti-HBc. Six (0.56% of all donations) samples fulfilled the consensus definition of OBI and showed low HBV DNA loads (all <6 IU/mL). Following nested polymerase chain reaction amplifications, HBV DNA sequences were obtained for 4 of these samples (1 nearly whole genome [3123 nt], 2 Pre-S/S regions [1,356 nt], and 1 S region [445 nt]). Phylogenetic analysis identified genotype E in all samples. DISCUSSION Around 1 in 100 Cameroonian blood donors screened who resulted HBsAg negative and anti-HBc positive carried occult HBV infection. HBsAg alone for screening prospective donors is not sufficient to eliminate the risk of HBV transfusion transmission in Cameroon, and because anti-HBc screening does not seem to be feasible without compromising blood supply, implementation of HBV nucleic acid testing could be considered when possible.

Abstract
Liver disease is a significant public health burden in both high-income and low-income countries, accounting for over 2 million annual, global deaths. Despite the significant mortality burden, liver diseases are historically a neglected problem due to a lack of accurate incidence and prevalence statistics, as well as national and international programmes targeting these diseases. A large portion of deaths due to liver diseases can be treated (eg, chronic hepatitis B), cured (eg, chronic hepatitis C) or prevented (eg, acute liver failure due to medications) if prompt diagnosis is made, but currently diagnostic methods fall short. Therefore, there is a critical need to fund the development of prompt, effective diagnostics for liver function, specifically in low-income and middle-income countries where the landscape for this testing is sparse. Here, we review and compare available and currently emerging diagnostic methods for liver injury in low-income and middle-income settings, while highlighting the opportunities and challenges that exist in the field.

Abstract
BACKGROUND Hepatitis B virus (HBV) nucleic acid amplification testing (NAAT) is important for the diagnosis and management of HBV infection. We evaluated the analytical performance of the cobas HBV NAAT (Roche Diagnostics GmbH, Mannheim, Germany) on the cobas 4800 System in comparison with COBAS AmpliPrep/COBAS TaqMan HBV Test (CAP/CTM HBV). METHODS Precision was evaluated using three levels of cobas HBV/HCV/HIV-1 Control Kit, and linearity was evaluated across the anticipated measuring range (10.0-1.0×109 IU/mL) at seven levels using clinical samples. Detection capability, including limit of blank (LOB), limit of detection (LOD) and limit of quantitation (LOQ), was verified using the 4th WHO International Standard for HBV DNA for NAT (NIBSC code: 10/266). Correlation between the two systems was compared using 205 clinical samples (102 sera and 103 EDTA plasma). RESULTS Repeatability and total imprecision (coefficient of variation) ranged from 0.5% to 3.8% and from 0.5% to 3.5%, respectively. Linearity (coefficient of determination, R2) was 0.999. LOB, LOD and LOQ were all acceptable within the observed proportion rate (85%). Correlation was very high between the two systems in both serum and plasma samples (correlation coefficient [r]=0.995). CONCLUSIONS The new cobas HBV real-time PCR assay on the cobas 4800 System showed reliable analytical performances.

Abstract
Areas with the highest burden of hepatitis B virus (HBV) infection are often low-middle-income countries with limited access to diagnosis due to isolation, affordability, and/or feasibility. Dried blood spots (DBSs) provide an alternative for remote areas where collection and transportation of serum is impractical. In this study, the application of DBS for serological and molecular detection of HBV and hepatitis D virus (HDV) was evaluated. Hepatitis B surface antigen was detected in 87 of 91 (95.6%) DBS. Seventeen of 21 (81%) had detectable HBeAg and 52 of 71 (73.2%) were anti-HBe positive. Anti-HD was detectable in 11 of 12 (91.6%) spiked control DBS after an initial failure to detect in patient DBS. HBV DNA was detected from 50 of 70 (71.4%) DBS with serum loads greater than 200 IU/mL in an in-house assay and 18 of 24 (75%) DBS with loads exceeding 389 IU/mL in a commercial assay. Using linear regression, HBV DNA loads from DBS were able to predict serum loads in 46 of 50 (92%) samples to within 1 log of actual serum load. HDV RNA was detected in 42 of 47 (89%) DBS with serum levels greater than 7200 IU/mL. DBSs are recommended for diagnosis of HBV, monitoring, and detection of high loads in pregnant women where peripheral blood testing remains unfeasible. Detection of HDV RNA from DBS may prove useful in endemic areas.

Abstract
BACKGROUND Hepatitis B virus (HBV)-specific effector CD8+ T cells are critical for viral clearance. To determine the effects of HBV-specific effector CD8+ T cells on HBV infection, we performed a meta-analysis of the available literature. METHODS Electronic database searches identified appropriately designed studies that detected specific CD8+ T cells in HBV-infected patients. Our main endpoints were the course of infection, seroconversion of HBV "e" antigen (HBeAg), the level of HBVDNA, and alanine aminotransferase (ALT) activity. We used a fixed/random model for analysis, according to the results of a heterogeneity test (P value of Q-squared, I2). RESULTS Our searches found five eligible articles. Pooled estimation of the reported results showed that levels of specific CD8+ T cells were significantly higher in patients with acute hepatitis B than in patients with chronic hepatitis B (odds ratio [OR] = 76.30, 95% confidence interval [CI]: 15.37-378.70). With respect to chronic hepatitis B, patients with <107 copies/ml HBVDNA had higher levels of specific CD8+ T cells relative to patients with >107 copies/ml HBVDNA, but the difference had no statistics significance (OR: 3.89, 95% CI: 0.71-21.33). Patients with negative HBeAg or positive anti-HBeAg antibody (anti-HBe) results had significantly higher levels of specific CD8+ T cells versus patients with positive HBeAg results (OR: 5.82, 95% CI: 1.41-24.13). There were no significant associations between the levels of specific CD8+ T cells and serum ALT activity (OR = 0.86, 95% CI: 0.01-74.15). CONCLUSION HBV-specific effector CD8+ T cells influence the disease activity in HBV-infected patients in various ways and determine prognosis by eliminating the virus. Therefore, efforts of studying HBV-specific effector CD8+ T cells focused vaccine are potentially needed.

[PMID: 30562636 DOI: 10.1016/j.biomaterials.2018.12.003] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2018] [Revised: 11/07/2018] [Accepted: 12/07/2018] [Indexed: 02/08/2023]
Abstract
A rational design approach is proposed for a multifunctional enzyme reagent for point-of-care diagnostics. The biomaterial reduces downstream isolation steps and eliminates immobilization coupling chemicals for integration in a diagnostic platform. Fusion constructs combined the central functional assay protein (e.g. monomeric sarcosine oxidase, mSOx, horseradish peroxidase, HRP), a visualizing protein (e.g. mCherry) and an in-built immobilization peptide (e.g. R5). Monitoring protein expression in E.coli was facilitated by following the increase in mCherry fluorescence, which could be matched to a color card, indicating when good protein expression has occurred. The R5 peptide (SSKKSGSYSGSKGSKRRIL) provided inbuilt affinity for silica and an immobilization capability for a silica based diagnostic, without requiring additional chemical coupling reagents. Silica particles extracted from beach sand were used to collect protein from crude protein extract with 85-95% selective uptake. The silica immobilized R5 proteins were stable for more than 2 months at room temperature. The Km for the silica-R52-mCh-mSOx-R5-6H was 16.5 ± 0.9 mM (compared with 16.5 ± 0.4 mM, 16.3 ± 0.3 mM, and 16.1 ± 0.4 mM for R52-mCh-mSOx-R5-6H, mSOx-R5-6H and mSOx-6H respectively in solution). The use of the "silica-enzymes" in sarcosine and peroxide assays was shown, and a design using particle sedimentation through the sample was examined. Using shadowgraphy and particle image velocimetry the particle trajectory through the sample was mapped and an hourglass design with a narrow waist shown to give good control of particle position. The hourglass biosensor was demonstrated for sarcosine assay in the clinically useful range of 2.5-10 μM in both a dynamic and end point measurement regime.

Abstract
Hepatitis B virus (HBV) infection is a major public health problem worldwide. China has the world’s largest burden of HBV infection and will be a major contributor towards the global elimination of hepatitis B disease by 2030. The country has made good progress in reducing incidence of HBV infection in the past three decades. The achievements are mainly due to high vaccination coverages among children and high coverage of timely birth-dose vaccine for prevention of mother-to-child transmission of HBV (both > 95%). However, China still faces challenges in achieving its target of 65% reduction in mortality from hepatitis B by 2030. Based on targets of the World Health Organization’s Global health sector strategy on viral hepatitis 2016–2021, we highlight further priorities for action towards HBV elimination in China. To achieve the impact target of reduced mortality we suggest that the service coverage targets of diagnosis and treatment should be prioritized. First, improvements are needed in the diagnostic and treatment abilities of medical institutions and health workers. Second, the government needs to reduce the financial burden of health care on patients. Third, better coordination is needed across existing national programmes and resources to establish an integrated prevention and control system that covers prevention, screening, diagnosis and treatment of HBV infection across the life cycle. In this way, progress can be made towards achieving the target of eliminating hepatitis B in China by 2030.

Abstract
BACKGROUND Globally, about 300 million people are infected with hepatitis B virus (HBV). Among the effective approaches to fight HBV infection is immunization. In 1989, an obligatory hepatitis B vaccine program was launched in Saudi Arabia. OBJECTIVE Assess hepatitis B surface antibody (anti-HBs) levels among the medical students before and after receiving booster doses of HBV vaccine. DESIGN Cross-sectional. SETTING Taibah University. SUBJECTS AND METHODS Students born between 1993 and 1995 were recruited in this study from the Occupational Health Clinic. Students were screened for anti-HBs levels using chemiluminescent microparticle immunoassay (CMIA) before and after booster HBV vaccine doses. MAIN OUTCOME MEASURES Anti-HBs levels before and after booster doses. SAMPLE SIZE 335. RESULTS About half of participants (n=164, 49%) had protective anti-HBs levels ( greater than or equal 10 mIU/mL) to the original primary series of HBV vaccine and received no booster doses. The reimaining 171 (51%) participants were at risk of HBV infection since their anti-HBs levels were less than 10 mIU/mL, despite having received the original primary HBV vaccine. The levels of anti-HBs were higher in female than in male students (P less than .001). In addition, female students showed a stronger humoral immune response to the booster vaccine than male students (P less than .001). When participants were given the three boosters, most participants (98.3%) showed anti-HBs levels of greater than or equal 10 mIU/mL. The results also showed a strong correlation between pre-booster and post-booster anti-HBs levels in the greater than or equal 10 mIU/mL group (r2= 0.52, P less than .001) but not in less than 10 mIU/mL group (r2= 0.003, P=.53). CONCLUSION A considerable portion of the participants (about 51%) were at risk of HBV infection since their anti-HBs levels were less than 10 mIU/mL. Booster doses significantly trigger memory immune response and this ensured their protection against the virus. Pre-booster anti-HBs level are a good predictive of post-booster anti-HBs levels in greater than or equal 10 mIU/mL group. LIMITATIONS The sample size was small. Shortage of collaborators. CONFLICT OF INTEREST None.

Abstract
Objective: A long persistent of Chronic Hepatitis B (CHB) infection may develop liver cirrhosis or hepatocellular
carcinoma (HCC) and about one million people die due to HBV -related liver cancer and end-stage liver disease annually
worldwide. The natural history of CHB phases comprises four phases: immune tolerant (HBeAg detectable and ALT
(Alanine Transaminase) normal, HBeAg-positive immune active (HBeAg detectable, anti-HBe antibodies undetectable
and ALT persistently elevated), HBeAg-negative immune active (HBeAg undetectable, anti-HBe antibodies present
and ALT persistently elevated), inactive carrier (HBeAg undetectable, anti-HBe antibodies present and ALT normal).
The evaluation of chronic hepatitis B phases is a crucial to manage the burden of disease and limit the development
of associated complications, such as cirrhosis and hepatocellular carcinoma (HCC). Thus this study conducted to
evaluate the natural history of HBV infection in patients with chronic HBV infection in Ahvaz city, Iran. Methods: In
this study, 71 non-treated CHB individuals were recruited including 44 (62%) males and 27(38%) females. The sera
were tested for HBV markers, HBsAg, HBcIgG, HBeAg, and HBeAb. ALT assay and HBV viral load were carried out
for each CHB individual. Results: Based on the analysis of serological, ALT status and viral load, the results showed:
immune tolerance 5(7%), eAg+ Immune Clearance 14(19.7%), eAg- Immune Clearance 29 (40.84%) and Inactive
Carrier 23 (32.39%). The HBeAg seroconversion was observed in a male age 18 year. Conclusion: The results of
the natural history of individuals with chronic hepatitis B phases CHB shows immune tolerance (7%), eAg+ Immune
Clearance (19.7%), eAg- Immune Clearance (40.84%) and Inactive Carrier (32.39%). To prevent the consequence of
CHB infection, an individual in immune tolerance phase should be tested periodically for ALT level, HBV markers,
HBsAg, HBcIgG, HBeAg, HBeAb and HBV viral load. Then decision-making therapy can be applied for CHB patients
at early stage of immune clearance.

Abstract
INTRODUCTION Hepatitis B is a serious public health problem across sub-Saharan Africa. Sierra Leone has no national hepatitis B strategy plan or high quality estimates of prevalence. Healthcare workers are perceived as an at-risk group for hepatitis B. We assessed the prevalence of hepatitis B among healthcare workers at two hospital sites in Freetown, Sierra Leone. METHODS In October 2017, healthcare workers were offered voluntary testing for hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs), hepatitis B core antibody (anti-HBc), hepatitis B e antigen (HBeAg) and hepatitis B e antibody (anti-HBe) using rapid lateral flow assay for all samples, followed by Enzyme Immunosorbent Assay to confirm positive results. Participants completed a questionnaire about knowledge, attitudes and practices concerning hepatitis B. HBsAg positive participants were invited to a clinic for further assessment. RESULTS Overall, 447 participants were tested for hepatitis B. Most (90.6%, 405/447) participants were nurses, 72.3% (323/447) were female and 71.6% (320/447) were 30 years or older. The prevalence of chronic hepatitis B (HBsAg positivity) was 8.7% (39 / 447, 95% CI 6.3-11.7%). There was no significant difference in prevalence by sex, age group, site of work or type of job. None of the 66.7% (26 / 39) of participants with chronic hepatitis B who attended the clinic met the 2015 WHO criteria to start treatment for hepatitis B on the basis of cirrhosis. Most participants (96.9% 432 / 446) stated that they were worried about their risk of hepatitis B at work. CONCLUSIONS Hepatitis B is highly prevalent among healthcare workers in Sierra Leone. It is unclear whether this reflects high community prevalence or is due to occupational risk. No participants with chronic hepatitis B needed to start treatment. In order to achieve the WHO target of elimination of viral hepatitis by 2030, introduction of birth dose vaccine for infants and catch-up vaccines for healthcare workers and healthcare students, together with a national hepatitis B screen and treat programme is advisable for Sierra Leone.

Abstract
BACKGROUND Sarcopenia is significantly associated with the degree of liver fibrosis. This study investigated the influence of sarcopenia on liver fibrosis in individuals with chronic hepatitis B. METHODS Data from the Korean National Health and Nutrition Examination Surveys 2008-2011 were analysed. The sarcopenia index (total appendicular skeletal muscle mass [kg]/body mass index [kg/m2 ]) was calculated using dual-energy X-ray absorptiometry. Sarcopenia was defined as the lowest quintile sarcopenia index value (cut-offs: 0.89 for men and 0.58 for women). The fibrotic burden was assessed using the nonalcoholic fatty liver disease fibrosis score and fibrosis-4 index. Significant fibrosis was defined as the highest nonalcoholic fatty liver disease fibrosis score quartile and a fibrosis-4 index ≥2.67. RESULTS Among the 506 respondents with chronic hepatitis B (258 men and 248 women), the nonalcoholic fatty liver disease fibrosis score and fibrosis-4 index identified sarcopenia and significant fibrosis in 126 (24.9%) and 217 (42.9%), respectively. Sarcopenia was significantly associated with significant fibrosis, regardless of the fibrosis prediction model used (all P < 0.05). When the study population was stratified according to metabolic factors, sarcopenia was specifically associated with an increased risk of significant fibrosis among subgroups with obesity, insulin resistance, metabolic syndrome and liver steatosis (odds ratio 2.37-3.57; all P < 0.05). An independent association between sarcopenia and significant fibrosis was identified after adjusting for other confounders (odds ratio 2.67-3.62 by the nonalcoholic fatty liver disease fibrosis score and 2.04-2.62 by the fibrosis-4 index; all P < 0.05). CONCLUSIONS Sarcopenia is associated with significant fibrosis in subjects with chronic hepatitis B, specifically those with obesity, insulin resistance, metabolic syndrome and liver steatosis.

Wright CM, Boudarène L, Ha NT, Wu O, Hawkins N. A systematic review of hepatitis B screening economic evaluations in low- and middle-income countries. BMC Public Health 2018; 18:373. [PMID: 29558894 PMCID: PMC5859762 DOI: 10.1186/s12889-018-5261-8] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2017] [Accepted: 03/06/2018] [Indexed: 12/30/2022] Open
Abstract
Background Chronic hepatitis B infection is a significant cause of morbidity and mortality worldwide; low- and middle-income countries (LMICs) are disproportionately affected. Economic evaluations are a useful decision tool to assess costs versus benefits of hepatitis B virus (HBV) screening. No published study reviewing economic evaluations of HBV screening in LMICs has been undertaken to date. Methods The following databases were searched from inception to 21 April 2017: MEDLINE, PubMed, EMBASE, CINAHL Plus, the Cochrane Library, Global Health and the Cost-effectiveness Analysis Registry. English-language studies were included if they assessed the costs against the benefits of HBV screening in LMICs. PROSPERO registration: CRD42015024391, 20 July 2015. Results Nine studies fulfilled the eligibility criteria. One study from Thailand indicated that adding hepatitis B immunoglobulin (HBIG) to HBV vaccination for newborns following screening of pregnant women might be cost-effective for some LMICs, though inadequate total funding and health infrastructure were likely to limit feasibility. A similar study from China indicated a benefit to cost ratio of 2.7 from selective HBIG administration to newborns, if benefits were considered from a societal perspective. Of the two studies assessing screening amongst the general adult population, a single cost-benefit analysis from China found a benefit to cost ratio (BCR) of 1.73 with vaccination guided by HBV screening of adults aged 21–39, compared to 1.42 with vaccination with no screening, both from a societal perspective. Community-based screening of adults in The Gambia with linkage to treatment yielded an incremental cost per disability-adjusted life year averted of $566 (in 2017 USD), less than two-times gross domestic product per capita for that country. Conclusions Screening with ‘catch-up’ vaccination for younger adults yielded benefits above costs, and screening linked with treatment has shown cost-effectiveness that may be affordable for some LMICs. However, interpretation needs to account for total cost implications and further research in LMICs is warranted as there were only nine included studies and evidence from high-income countries is not always directly applicable.

Abstract
Hepatitis B virus infection is still a major public health problem worldwide, since more than 350 million people have chronic, lifelong infection and nearly 1 million deaths occur each year owing to complications. Most infections are acquired at birth or during early childhood. Nowadays, low- and middle-income countries bear the majority of the burden of hepatitis B-related liver cancer deaths despite the availability of an effective vaccine and antiviral treatments. In this review the epidemiology, strategies of prevention and the recent advances in therapy, genotype diversity and resistance are discussed.

Abstract
Chronic infection with hepatitis B virus (HBV) progresses through multiple phases, including immune tolerant, immune active, immune control, and, in a subset of patients who achieve immune control, reactivation. The first, the immune tolerant phase, is considered to be prolonged in duration but essentially benign in nature, lacking long-term consequences, and thus not recommended for antiviral therapy. This review challenges the notion that the immune tolerant phase is truly benign and considers the possibility that events during this phase may contribute significantly to cirrhosis, hepatocellular carcinoma (HCC), and the premature death of 25% of HBV carriers worldwide. Thus, earlier treatment than recommended by current guidelines should be considered. Low therapeutic coverage exacerbated by restrictive treatment guidelines may facilitate disease progression in many patients but also increase the risk of neonatal and horizontal transmission from untreated mothers to their children. While a prophylactic vaccine exists, there are many areas worldwide where the treatment of adults and the delivery of an effective vaccination course to newborns present difficult challenges.

Complete and Incomplete Hepatitis B Virus Particles: Formation, Function, and Application. Viruses 2017; 9:v9030056.

Abstract
Hepatitis B virus (HBV) is a para-retrovirus or retroid virus that contains a double-stranded DNA genome and replicates this DNA via reverse transcription of a RNA pregenome. Viral reverse transcription takes place within a capsid upon packaging of the RNA and the viral reverse transcriptase. A major characteristic of HBV replication is the selection of capsids containing the double-stranded DNA, but not those containing the RNA or the single-stranded DNA replication intermediate, for envelopment during virion secretion. The complete HBV virion particles thus contain an outer envelope, studded with viral envelope proteins, that encloses the capsid, which, in turn, encapsidates the double-stranded DNA genome. Furthermore, HBV morphogenesis is characterized by the release of subviral particles that are several orders of magnitude more abundant than the complete virions. One class of subviral particles are the classical surface antigen particles (Australian antigen) that contain only the viral envelope proteins, whereas the more recently discovered genome-free (empty) virions contain both the envelope and capsid but no genome. In addition, recent evidence suggests that low levels of RNA-containing particles may be released, after all. We will summarize what is currently known about how the complete and incomplete HBV particles are assembled. We will discuss briefly the functions of the subviral particles, which remain largely unknown. Finally, we will explore the utility of the subviral particles, particularly, the potential of empty virions and putative RNA virions as diagnostic markers and the potential of empty virons as a vaccine candidate.

[PMID: 28069363 DOI: 10.1016/j.vaccine.2016.12.062] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2016] [Revised: 12/24/2016] [Accepted: 12/28/2016] [Indexed: 02/08/2023]
Abstract
BACKGROUND Neutralizing antibodies (anti-HBs) after immunization with hepatitis B virus (HBV) vaccines against HBV surface antigen (HBsAg) wane after 10-15years. We analyzed the effect of an adolescent booster given to vaccination-protected children born to mothers with different HBsAg-carrying status against HBV infection in their mature adulthood. METHODS A total of 9793 individuals, who were HBsAg-negative at childhood (baseline) and donated blood samples, both during childhood and adulthood, from the vaccination group in "Qidong Hepatitis B Intervention Study", were enrolled. Among them 7414 received a one-dose, 10μg-recombinant HBV vaccine booster at 10-14years of age. At endpoint (23-28years of age), we determined the HBV serological markers and quantified their serum HBV-DNA in each of the chronic HBV-infected adults. RESULTS Fifty-seven adults were identified as chronic HBV infection, indicated by HBsAg(+)&anti-HBc(+) for more than 6months. The individuals who were born to HBsAg-positive mothers (high-risk adults) had significantly increased risk of developing chronic HBV infections in adulthood compared with those who were born to HBsAg-negative mothers; the adjusted odds ratio (OR) was 12.56, 95%CI:7.14-22.08. The seronegative status of anti-HBs at 10-11years of age significantly increased the risk of HBV infections among the high-risk adults. When HBsAg(-)&anti-HBc(+) children who were born to HBsAg-positive mothers 70% of them remained as the status and 10% of them developed HBsAg(+)&anti-HBc(+). While when they were born to HBsAg-negative mothers 1.05% HBsAg(-)&anti-HBc(+) children developed HBsAg(+)&anti-HBc(+) and 24.74% of them remained as the status in 12-18years. One dose of adolescent booster showed significant protection on high-risk adults from chronic HBV infection; P for trend was 0.015. CONCLUSIONS Maternal HBsAg-positive status was an independent risk factor for vaccination-protected children to develop HBV breakthrough infection in adulthood. Adolescent boosters might be appropriate for high-risk individuals who were born to HBsAg-positive mothers when their serum anti-HBs<10mIU/ml.
