Abstract
Viral hepatitis represents a major danger to public health, and is a globally leading cause of death. The five liver-specific viruses: Hepatitis A virus, hepatitis B virus, hepatitis C virus, hepatitis D virus, and hepatitis E virus, each have their own unique epidemiology, structural biology, transmission, endemic patterns, risk of liver complications, and response to antiviral therapies. There remain few options for treatment, in spite of the increasing prevalence of viral-hepatitis-caused liver disease. Furthermore, chronic viral hepatitis is a leading worldwide cause of both liver-related morbidity and mortality, even though effective treatments are available that could reduce or prevent most patients' complications. In 2016, the World Health Organization released its plan to eliminate viral hepatitis as a public health threat by the year 2030, along with a discussion of current gaps and prospects for both regional and global eradication of viral hepatitis. Today, treatment is sufficiently able to prevent the disease from reaching advanced phases. However, future therapies must be extremely safe, and should ideally limit the period of treatment necessary. A better understanding of pathogenesis will prove beneficial in the development of potential treatment strategies targeting infections by viral hepatitis. This review aims to summarize the current state of knowledge on each type of viral hepatitis, together with major innovations.

Abstract
Hepatitis B virus (HBV) infection is a major player in chronic hepatitis B that may lead to the development of hepatocellular carcinoma (HCC). HBV genetics are diverse where it is classified into at least 9 genotypes (A to I) and 1 putative genotype (J), each with specific geographical distribution and possible different clinical outcomes in the patient. This diversity may be associated with the precision medicine for HBV-related HCC and the success of therapeutical approaches against HCC, related to different pathogenicity of the virus and host response. This Editorial discusses recent updates on whether the classification of HBV genetic diversity is still valid in terms of viral oncogenicity to the HCC and its precision medicine, in addition to the recent advances in cellular and molecular biology technologies.

High Prevalence of Hepatitis B Virus Drug Resistance Mutations to Lamivudine among People with HIV/HBV Coinfection in Rural and Peri-Urban Communities in Botswana. Viruses 2024; 16:592. [PMID: 38675933 PMCID: PMC11054684 DOI: 10.3390/v16040592] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 04/07/2024] [Accepted: 04/09/2024] [Indexed: 04/28/2024] Open
Abstract
(1) Background: We aimed to determine the prevalence of hepatitis B virus (HBV) resistance-associated mutations (RAMs) in people with HBV and human immunodeficiency virus (HBV/HIV) in Botswana. (2) Methods: We sequenced HBV deoxyribonucleic acid (DNA) from participants with HBV/HIV from the Botswana Combination Prevention Project study (2013-2018) using the Oxford Nanopore GridION platform. Consensus sequences were analyzed for genotypic and mutational profiles. (3) Results: Overall, 98 HBV sequences had evaluable reverse transcriptase region coverage. The median participant age was 43 years (IQR: 37, 49) and 66/98 (67.4%) were female. Most participants, i.e., 86/98 (87.8%) had suppressed HIV viral load (VL). HBV RAMs were identified in 61/98 (62.2%) participants. Most RAMs were in positions 204 (60.3%), 180 (50.5%), and 173 (33.3%), mostly associated with lamivudine resistance. The triple mutations rtM204V/L180M/V173L were the most predominant (17/61 [27.9%]). Most participants (96.7%) with RAMs were on antiretroviral therapy for a median duration of 7.5 years (IQR: 4.8, 10.5). Approximately 27.9% (17/61) of participants with RAMs had undetectable HBV VL, 50.8% (31/61) had VL < 2000 IU/mL, and 13/61 (21.3%) had VL ≥ 2000 IU/mL. (4) Conclusions: The high prevalence of lamivudine RAMs discourages the use of ART regimens with 3TC as the only HBV-active drug in people with HIV/HBV.

Abstract
Chronic hepatitis B virus (HBV) infection remains a significant public health concern, particularly in Africa, where there is a substantial burden. HBV is an enveloped virus, with isolates being classified into ten phylogenetically distinct genotypes (A - J) determined based on full-genome sequence data or reverse hybridization-based diagnostic tests. In practice, limitations are noted in that diagnostic sequencing, generally using Sanger sequencing, tends to focus only on the S-gene, yielding little or no information on intra-patient HBV genetic diversity with very low-frequency variants and reverse hybridization detects only known genotype-specific mutations. To resolve these limitations, we developed an Oxford Nanopore Technology (ONT)-based HBV genotyping protocol suitable for clinical virology, yielding complete HBV genome sequences and extensive data on intra-patient HBV diversity. Specifically, the protocol involves tiling-based PCR amplification of HBV sequences, library preparation using the ONT Rapid Barcoding Kit, ONT GridION sequencing, genotyping using Genome Detective software, recombination analysis using jpHMM and RDP5 software, and drug resistance profiling using Geno2pheno software. We prove the utility of our protocol by efficiently generating and characterizing high-quality near full-length HBV genomes from 148 left-over diagnostic Hepatitis B patient samples obtained in the Western Cape province of South Africa, providing valuable insights into the genetic diversity and epidemiology of HBV in this region of the world.

Abstract
Hepatocellular carcinoma (HCC), a considerable leading cause of cancer-related deaths worldwide, is the most common primary liver cancer with poor prognosis and outcome. Many advances in prevention, screening, and new technologies in diagnostics and therapy have been achieved, but its incidence and mortality remain increasing. Co-infection of another viral disease in HCC patients with pregnancy might exacerbate the condition and double the mortality rate. The aim of this case report was to describe the co-infection of coronavirus disease 2019 (COVID-19) in an HCC patient during pregnancy. A 26-year-old woman with 16-17 weeks of gestation was admitted to Dr. Zainoel Abidin Hospital, Banda Aceh, Indonesia with shortness of breath. The patient also reported that the abdomen expanded rapidly in the last three weeks, followed by severe pain and collateral vein appearance. Laboratory findings revealed anemia, leukocytosis, HBsAg reactive, hypoalbuminemia, hyperbilirubinemia, elevated liver enzymes, increased alpha-fetoprotein (AFP), and cancer antigen 125 (CA-125). Ultrasonography indicated gestation with a single fetus, an enlarged liver with a 9.9 × 9.4 cm nodule, and massive ascites. The patient was also RT-PCR-confirmed COVID-19. On day 8 of hospitalization, the patient suddenly reported severe abdominal pain. Ultrasonography revealed fetal distress immediately followed by fetal death. Adequate management of cancer pain, continuous evacuation of ascites, and other supportive care could not save the patient who died on the day 17 of hospitalization. In this case, we found no proof that the patient experienced cirrhosis prior to HCC. Pregnancy through hormonal alteration is thought to be the aggravating factor that accelerates the progression of pre-existing liver disease into carcinoma and infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) worsened the outcome in this patient.

Makan N, Song E, Kinge CW, Kramvis A. Hepatitis B virus immunity prior to and after administration of a ‘booster’ dose of vaccine among health-care students at a South African university. Vaccine X 2023; 14:100284. [PMID: 37063305 PMCID: PMC10090248 DOI: 10.1016/j.jvacx.2023.100284] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Revised: 02/02/2023] [Accepted: 03/16/2023] [Indexed: 03/30/2023] Open
Abstract
Background Health-care students (HCSs) are at risk of occupational exposure to hepatitis B virus (HBV) infection despite an effective hepatitis B vaccine (HepB) being available. The majority of current HCSs are born after HepB was introduced into the South African Expanded Programme on Immunisation in 1995. Thus, it is assumed that having received HepB in infancy, a single 'booster' dose would suffice. This study aimed to investigate HBV immunity prior to and after administration of a HepB 'booster' dose. Methods Hepatitis B surface antibody (anti-HBs) levels were determined in first year HCSs at the University of the Witwatersrand, before and after receiving the 'booster'. Participant demographics and HepB history were captured using a structured questionnaire. Results Before receiving the 'booster', 56% (101/180) had anti-HBs < 10 mIU/mL and were non-immune. A further 35% had anti-HBs levels of 10 - 99 mIU/mL, and 9% had ≥100 mIU/mL. <30% of HCSs self-reported completion of a three-dose primary series, which was significantly associated with higher baseline anti-HBs levels compared to those with a partial schedule (p = 0.045). Following vaccination, 39% (71/180) returned for follow-up with a significant median (IQR) increase of 476 (151 - 966) mIU/mL (p < 0.001). Of the 45 students who had non-immune baseline levels, 73% (33/45) responded with ≥100 mIU/mL, 16% (7/45) with 10 - 99 mIU/mL and 11% (5/45) remained non-immune. Levels of ≥100 mIU/mL were achieved by 100% of students with baseline levels ≥10 mIU/mL (n = 26). Conclusion More than half of the HCSs were not immune to HBV prior to receiving the recommended 'booster' vaccine. Following vaccination, 7% (5/71) remained unprotected. This study highlights that in the absence of vaccination records and without confirming the immune status of HCSs, it cannot be assumed that HCSs will be protected following a 'booster'. Policy reform and inclusion of serological tests for immunity prior to HCSs initiating clinical exposure are recommended.

Abstract
BACKGROUND Identification and monitoring of HBV genotype variations is important, since that can help forecast the likelihood of developing serious liver disease and how well patients respond to antiviral medication. Given that HBV genotyping tests are not widely available in our healthcare system, this study characterized HBV genotypes in pregnant women seeking prenatal treatment in northern Ghana. METHOD By a cross-sectional approach, 2071 pregnant women seeking antenatal care in health facilities in northern Ghana were screened for HBV infection using hepatitis B surface antigen (HBsAg) rapid diagnostic test kit. The women were aged between 17 and 41 years, were of varying gravidae (primigravidae and multigravidae) and gestational age (first, second and third trimesters). A confirmatory PCR assay was used to detect HBsAg, and the distribution of HBV genotypes was determined using a nested PCR assay. RESULTS Three HBV genotypes (A, D and E) were detected among the pregnant women, of which 175 (91.6%) had genotype E, 9 (4.7%) had mixed genotypes A and E, 5 (2.6%) had mixed genotypes D and E, and 2 (1.1) had mixed genotypes A, D and E. The proportions of women with the different HBV genotypes were independent of age (p = 0.925), gravidity (p = 0.193, χ2 = 4.729) and gestational age (p = 0.227, χ2 = 8.152). CONCLUSION This study for the first-time characterized circulating HBV genotypes in pregnant women in northern Ghana, which reveals genotypes A and D are found in mixed infections with genotype E. The findings have clinical implications on the management of chronic HBV infection among pregnant women in northern Ghana.

REVISTA BRASILEIRA DE EPIDEMIOLOGIA 2023; 26:e230029. [PMID: 37403865 DOI: 10.1590/1980-549720230029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Accepted: 10/04/2023] [Indexed: 07/06/2023] Open
Abstract
OBJECTIVE To analyze the spatial distribution and the temporal trend of the hepatitis mortality rate in Brazil from 2001 to 2020. METHODS Ecological, temporal, and spatial study on mortality from hepatitis in Brazil with data from the Mortality Information System (Sistema de Informações sobre Mortalidade - SIM/DATASUS). Information was stratified by year of diagnosis, region of the country, municipalities (of residence). Standardized mortality rates (SMR) were calculated. The temporal trend was estimated by Prais-Winsten regression and the spatial distribution by the Global Moran Index (GMI). RESULTS The highest SMR means in Brazil were for Chronic viral hepatitis with 0.88 deaths per 100,000 inhabitants (SD=0.16), followed by Other viral hepatitis with 0.22/100,000 (SD=0.11). In Brazil, the temporal trend of mortality from Hepatitis A was -8.11% per year (95%CI -9.38; -6.82), while for Hepatitis B it was -4.13% (95%CI -6.03; -2.20), of Other viral hepatitis of -7.84% (95%CI -14.11; -1.11) and of Unspecified Hepatitis -5.67% per year (95%CI -6.22; -5.10). Mortality due to chronic viral hepatitis increased by 5.74% (95%CI 3.47; 8.06) in the North and 4.95% in the Northeast (95%CI 0.27; 9.85). The Moran Index (I) for Hepatitis A was 0.470 (p<0.001), for Hepatitis B 0.846 (p<0.001), Chronic viral hepatitis=0.666 (p<0.001), other viral hepatitis=0.713 (p<0.001), and Unspecified Hepatitis=0.712 (p<0.001). CONCLUSION The temporal trend of hepatitis A, B, other viral, and unspecified hepatitis was decreasing in Brazil, while mortality from chronic hepatitis was increasing in the North and Northeast.

Abstract
Vaccination against hepatitis B virus (HBV) remains the most effective strategy against HBV infection in humans. The present review summarized the optimal vaccination strategies against HBV in childhood. The following points are discussed: i) When and how the first HBV vaccines were developed; ii) the dosages, schedules and injection routes that are used for HBV vaccination; iii) the contraindications for HBV vaccination in the general paediatric population; iv) the challenges with the use of multivalent vaccines; v) the long-term immunogenicity and duration of protection against HBV; vi) the use of selective HBV vaccination and the hepatitis B immune globulin strategy in HBV-exposed infants; and vii) the effectiveness of the current HBV vaccination schemes. The present review is based on a Paediatric Virology Study Group (PVSG) webinar performed in the context of the 8th Workshop on Paediatric Virology.
