RESUMEN

Since its discovery in 1965, our understanding of the hepatitis B virus (HBV) replication cycle and host immune responses has increased markedly. In contrast, our knowledge of the molecular biology of hepatitis delta virus (HDV), which is associated with more severe liver disease, is less well understood. Despite the progress made, critical gaps remain in our knowledge of HBV and HDV replication and the mechanisms underlying viral persistence and evasion of host immunity. The International HBV Meeting is the leading annual scientific meeting for presenting the latest advances in HBV and HDV molecular virology, immunology, and epidemiology. In 2023, the annual scientific meeting was held in Kobe, Japan and this review summarises some of the advances presented at the Meeting and lists gaps in our knowledge that may facilitate the development of new therapies.

RESUMEN

Foreign-born (FB) persons represent a large proportion of adults with chronic hepatitis B (CHB) in Canada due to higher prevalence rates in countries of birth for FB persons. Suboptimal awareness and low rates of hepatitis delta virus (HDV) testing contribute to underdiagnosis and gaps in accurate estimates of Canada HDV prevalence. We aim to provide an assessment of CHB and HDV prevalence in Canada using a comprehensive literature review and meta-analysis. A comprehensive literature review of articles reporting HBsAg seroprevalence and anti-HDV prevalence was conducted to calculate country-specific rates and pooled prevalence of CHB and HDV using meta-analyses. Country-specific CHB and HDV rate estimates were combined with number of FB persons in Canada in 2021 from Statistics Canada to estimate total numbers of FB with CHB and HDV, respectively. These estimates were combined with estimates of Canada-born persons with CHB and HDV to yield the total number of persons with CHB and HDV. In 2021, we estimated 0.550 million (M) (95% CI 0.488-0.615) persons with CHB; 0.344 M (95% CI 0.288-0.401) were FB and 0.206 M (95% CI: 0.200-0.214) were Canada-born. The weighted average HDV prevalence among FB persons in Canada was 5.19% (17,848 [95% CI 9611-26,052] persons), among whom 50% emigrated from Asia and 31% from Africa. When combined with estimates of Canada-born persons with HDV, we estimate 35,059 (95% CI: 18,744-52,083) persons with HDV in Canada. In conclusion, we estimate 0.550 M and 35,059 persons living with CHB and HDV, respectively, in Canada in 2021.

RESUMEN

Chronic hepatitis B infection (CHB) affects 300 million people worldwide and is being targeted by the United Nations 2030 Sustainable Development Goals (SDGs) and the World Health Organisation (WHO), working towards elimination of hepatitis B virus (HBV) as a public health threat. In this piece, we explore the evidence and potential impact of peer support to enhance and promote interventions for people living with CHB. Peer support workers (PSWs) are those with lived experience of an infection, condition or situation who work to provide support for others, aiming to improve education, prevention, treatment and other clinical interventions and to reduce the physical, psychological and social impacts of disease. Peer support has been shown to be a valuable tool for improving health outcomes for people living with human immunodeficiency virus (HIV) and hepatitis C virus (HCV), but to date has not been widely available for communities affected by HBV. HBV disproportionately affects vulnerable and marginalised populations, who could benefit from PSWs to help them navigate complicated systems and provide advocacy, tackle stigma, improve education and representation, and optimise access to treatment and continuity of care. The scale up of peer support must provide structured and supportive career pathways for PSWs, account for social and cultural needs of different communities, adapt to differing healthcare systems and provide flexibility in approaches to care. Investment in peer support for people living with CHB could increase diagnosis, improve retention in care, and support design and roll out of interventions that can contribute to global elimination goals.

RESUMEN

BACKGROUND AND AIMS: Suboptimal awareness and low rates of hepatitis delta virus (HDV) testing contribute to underdiagnosis and gaps in accurate estimates of U.S. HDV prevalence. We aim to provide an updated assessment of HDV prevalence in the U.S. using a comprehensive literature review and meta-analysis approach. METHODS: A comprehensive literature review of articles reporting HBsAg seroprevalence and anti-HDV prevalence was conducted to calculate country-specific rates and pooled prevalence of CHB and HDV using meta-analyses. Country-specific CHB and HDV rate estimates were combined with number of foreign-born (FB) persons in the U.S. in 2022 from U.S. Census Bureau to estimate total numbers of FB with CHB and HDV, respectively. These estimates were further combined with updated estimates of U.S.-born persons with CHB and HDV to yield the total number of persons with CHB and HDV. RESULTS: In 2022, we estimated 1.971 million (M) (95% CI 1.547-2.508) persons with CHB; 1.547 M (95% CI 1.264-1.831) were FB and 0.424 M (95% CI: 0.282-0.678) were U.S.-born. The weighted average HDV prevalence among FB persons in the U.S. was 4.20% (64 938 [95% CI 33055-97 392] persons), among whom 45% emigrated from Asia, 25% from Africa, and 14% from Europe. When combined with updated estimates of U.S.-born persons with HDV, we estimate 75 005 (95% CI: 42187-108 393) persons with HDV in the U.S. CONCLUSIONS: Including both FB and U.S.-born persons, we estimated that 1.971 M and 75 005 persons were living with CHB and HDV, respectively, in the U.S. in 2022.

RESUMEN

Almost 300 million people are living with chronic hepatitis B infection worldwide and most remain undiagnosed and at risk for liver cancer. In 2015 the World Health Organization (WHO) developed guidelines for the prevention, care, and treatment of persons with chronic hepatitis B and in early 2023 began to work on updating these guidelines. In March 2023, a self-administered, anonymous online survey was launched, aiming to identify patient preferences related to the clinical management of hepatitis B including current management, treatment, and care experiences, preferences regarding engagement with providers, and preferences related to simplifying hepatitis B care access. A sample of 560 individuals living with hepatitis B (self-identified as HBsAg positive) from 76 countries completed the survey. Key findings demonstrated that less than half (49%, N = 268) of participants regularly visited a doctor to check the health of their liver (every 6-12 months), with 37% of participants prescribed antiviral medication by a specialist (82%, N = 167) or general practitioner (13%, N = 26). Participants reported not being actively involved in care decision making with their providers (42%, N = 217), with an overwhelming majority wanting to participate in hepatitis B management and treatment choices (85%, N = 435). Participants provided qualitative and quantitative details using open-ended responses within the survey about challenges with medication affordability and receiving care from a knowledgeable provider. Overall findings demonstrated key gaps in care, management, and treatment access related to hepatitis B: identifying these gaps can be used to identify areas for improvement along the care continuum for viral hepatitis. The survey found a need for the comprehensive simplification of clinical management and health care services related to hepatitis B. A thematic analysis of the open-ended survey responses highlighted major overarching themes including the cost and access burdens associated with hepatitis B management and treatment, and challenges in finding knowledgeable providers. Results from this mixed methods survey were used to inform the WHO hepatitis B guidelines update. Efforts should continue to explore public health approaches to address barriers and facilitators to testing, care, and treatment for people with hepatitis B to improve awareness of hepatitis B and access, care, and treatment among patients and providers.

RESUMEN

Over 250 million individuals live with chronic hepatitis B (CHB) infection worldwide. A significant proportion of these people often face discrimination defined as the unjust, unfair, or prejudicial treatment of a person on the grounds of their hepatitis B status. Hepatitis B related discrimination has not been widely documented in the literature. This study aims to describe the lived experience of discrimination, document its impact, and shed light on its consequences. A hepatitis B discrimination registry was launched to record self-reported discrimination associated with hepatitis B. The registry included brief demographic questions (age, gender, country of origin), discrimination-specific questions (where, when, and how discrimination occurred), and open-ended questions to detail specific experiences. The registry was distributed to hepatitis B patient/people-focused listservs, social media networks, and community-based organizations around the globe. Descriptive data were analyzed including comparative analysis by country and type of discrimination occurring along with qualitative data (open-ended responses) which were analyzed using thematic analysis techniques A total of 569 individuals responded to the survey between May 2021 and December 2023. Individuals identified as residing in the Philippines (34%; N = 194), Nigeria (11%; N = 60), Pakistan (8%; N = 45), India (6%, N = 34), Uganda (5%; N = 31), the United States of America (4%, N = 26), Ghana (3%; N = 15), Ethiopia (2%; N = 14), and other countries in smaller number with a total of 65 countries reported discrimination at least by one individual. Of these, 461 individuals shared details about their experiences of discrimination with most relating to restrictions on access to work visas, followed by in-country hepatitis B-related employment restrictions, educational-based discrimination, discrimination within the community and health facilities, and the emotional impact of hepatitis B discrimination. This is the largest primary collection of hepatitis B-associated discrimination events and highlights how hepatitis B discrimination clearly has a significant impact on individuals' lives and limits economic opportunities regardless of physical symptoms. Such impacts likely act as barriers to diagnosis and engagement in care, so need to be addressed to achieve the global hepatitis B elimination goals. The data highlight a need for global, national responses and more systematic responses to discrimination experienced by people with hepatitis B.

RESUMEN

BACKGROUND: People with chronic hepatitis B (CHB) commonly experience social and self-stigma. This study sought to understand the impacts of CHB-related stigma and a functional cure on stigma. METHODS: Adults with CHB with a wide range of age and education were recruited from 5 countries and participated in 90-minute qualitative, semi-structured interviews to explore concepts related to CHB-associated stigma and its impact. Participants answered open-ended concept-elicitation questions regarding their experience of social and self-stigma, and the potential impact of reduced CHB-related stigma. RESULTS: Sixty-three participants aged 25 to 71 years (15 from the United States and 12 each from China, Germany, Italy, and Japan) reported emotional, lifestyle, and social impacts of living with CHB, including prejudice, marginalization, and negative relationship and work experiences. Self-stigma led to low self-esteem, concealment of CHB status, and social withdrawal. Most participants stated a functional cure for hepatitis B would reduce self-stigma. CONCLUSIONS: CHB-related social and self-stigma are widely prevalent and affect many aspects of life. A functional cure for hepatitis B may reduce social and self-stigma and substantially improve the health-related quality of life of people with CHB. Incorporating stigma into guidelines along with infectivity considerations may broaden the patient groups who should receive treatment.

RESUMEN

Asian, Pacific Islander, African, and Caribbean communities in the U.S. are heavily impacted by chronic hepatitis B (HBV) and hepatocellular carcinoma (HCC). Educating these groups about the link between the two diseases is imperative to improve screening rates and health outcomes. This study aims to identify and incorporate preferred mediated communication methods into community-specific educational campaigns which emphasize the connection between the conditions, to promote uptake of prevention and management behaviors for HBV and HCC. Fifteen focus groups and two key informant interviews were conducted with Micronesian, Chinese, Hmong, Nigerian, Ghanaian, Vietnamese, Korean, Somali, Ethiopian, Filipino, Haitian, and Francophone West African communities. Data were analyzed using thematic coding and analysis. Findings demonstrate that all communities preferred materials be offered in both English and native languages and requested that materials highlight the connection between HBV and HCC. Delivery channel preferences and messaging themes varied by group. This study provides insight into community-specific preferences for learning about HBV and HCC. The findings can be used to design culturally and linguistically tailored, multi-platform, health education campaigns to facilitate improved HBV screening and vaccination rates and increase knowledge about HCC risk among highly impacted communities in the U.S.

RESUMEN

BACKGROUND AND AIMS: Although prevalence of chronic hepatitis B (CHB) in the USA includes 0.42 million (range, 0.28-0.67) U.S.-born persons, foreign-born (FB) persons contribute a substantially larger number to the burden of CHB in the USA. Over the past decade, patterns of U.S. immigration have changed and many countries have implemented HBV prevention programs. This study aims to estimate the number of FB persons with CHB in the USA by country of origin, updating our 2011 study. APPROACH AND RESULTS: We performed systematic searches for articles published in 2009-2019 reporting HBsAg seroprevalence in emigrants and in-country populations of 117 countries. Data meeting inclusion criteria were combined with data from our 2011 study to calculate pooled prevalence estimates for 99 countries using meta-analyses (total 2,800 surveys involving 112 million subjects). Combining country-specific CHB rate estimates with the number of FB in the USA in 2018, by country of origin from the U.S. Census Bureau, we estimate that the number of FB with CHB in the USA in 2018 was 1.47 million (95% CI, 1.21-1.73), substantially higher than previously reported. The weighted average CHB prevalence for all FB in the USA in 2018 was 3.07%. Approximately 59% of FB with CHB in the USA in 2018 emigrated from Asia, 19% from the Americas, and 15% from Africa. Subgroup analyses found that for many countries, CHB rates are higher in males than females and have declined over the past three decades, but no consistent pattern is observed between emigrant and in-country rates. CONCLUSIONS: Including FB and U.S.-born persons, the total prevalence of CHB in the USA may be as high as 2.4 million.

RESUMEN

BACKGROUND: An estimated 296 million individuals live with chronic hepatitis B worldwide, most have not been diagnosed and remain at risk of liver disease and cancer. People with hepatitis B often face discrimination that denies them employment or education opportunities, results in unfair treatment at work or in school, limits their ability to emigrate to certain countries, and in some cases prohibits them from serving in the military. Discrimination specific to hepatitis B has not been widely documented within the literature. This study aims to investigate and describe hepatitis B related discrimination, document discrimination occurring around the globe, and provide initial recommendations for addressing discrimination using key informant interviews. METHODS: Purposive and snowball sampling were used to identify potential key informants for qualitative interview. Key informants identified as community health leaders, public health scientists, doctors, and researchers, many of whom were also living with hepatitis B. Using a semi-structured guide, participants were asked to describe their experience and any challenges for people living with hepatitis B including marginalization and its' consequences. A codebook was used to guide the organization of data for analysis, and all transcripts N = 17 were double coded. RESULTS: The overarching themes identified from interviews demonstrate explicit experiences with discrimination of those directly affected, the psychological responses, and the negative health outcomes associated with the unvirtuous cycle of discrimination. All key informants reported on the substantial quality of life implications and often poorer health outcomes resulting from hepatitis B discrimination. Participants also identified the significant impact of hepatitis B discrimination occurring within a range of education-based services across several countries as well as military exclusion or removal if individuals are found to have hepatitis B. CONCLUSION: Our data demonstrate that hepatitis B discrimination has a significant impact. Discrimination can occur at various points in life from education, to seeking employment, to marriage, to restrictions on entry, travel and stay in other countries. This study demonstrates the impact of discrimination and the need for future research that can lead to policy change and protections for people living with and impacted by hepatitis B.

RESUMEN

Those living with chronic hepatitis B virus (HBV) require years, if not decades, of regular monitoring to prevent liver complications from occurring. An estimated 292 million people were living with chronic HBV globally in 2018 with approximately 2.4 million of those residing within the United States (US). This study is one of the first of its kind that aims to explore the treatment preferences for those living with chronic HBV through qualitative interviews. Participant data were collected by in-depth telephone interviews using a semi-structured discussion guide. A codebook guided the organization of data, and codes were developed by review of the literature (a priori) and through line-by-line reading of a subsample of queries. All data transcripts (N = 19) were independently double coded. Overarching themes identified from the data specific to the treatment modalities and implications of a functional HBV cure included the concern about side effects, treatment modality, frequency, duration, cost-effectiveness and overall impact on their lives. Qualitative data analysis revealed the significant impact that an HBV functional cure would have on quality of life. Benefits of a cure were described as not having a finite course of treatment, improving overall vitality, and reducing the fear and anxiety associated with lifelong infection and potential development of liver cancer. Many individuals expressed the desire for a cure for HBV, stating it would be life-changing, and a 'miracle'. As new therapies are in development, more research should examine in detail the treatment preferences of those living with HBV.

RESUMEN

BACKGROUND: An estimated between 257 and 292 million people live with chronic HBV globally. While much is known about the causes, and epidemiology of HBV, little is understood about the quality of life and impact of HBV on those living with the infection. METHODS: A random sample of HBV-related email queries sent to the Hepatitis B Foundation, a U.S.-based non-profit organization, over a 12-month period in 2018-2019 were retrieved, tabulated, and analyzed qualitatively to highlight information needs and explore the experiences of people living with HBV and their families and loved ones. Codebook development was informed by the literature and through line-by-line reading of a sub-sample of queries. Data analysis was facilitated by NVivo12 software. Data were coded independently by two members of the research team and intercoder reliability was assessed to assure coding accuracy throughout the coding phase. RESULTS: A total of 338 queries from people around the globe were identified and analyzed. The analysis revealed three thematic groups: 1) health-specific challenges associated with diagnosis and treatment, 2) emotional needs related to experiences with HBV stigma, discrimination, fear, social isolation, and distress and 3) informational needs related to HBV prevention and transmission, and interpretation of laboratory tests. CONCLUSIONS: People living with HBV are in need of information to manage their disease and prevent its spread. Analysis of queries uncovered significant misconceptions about HBV transmission and treatment. Additionally, the emotional and psychological impact of an HBV diagnosis on those living with the infection is significant. There is a clear need for patient and community education to expand knowledge and awareness of HBV globally to achieve 2030 WHO HBV elimination goals.

RESUMEN

In the United States (U.S.), up to 2.2 million individuals have been chronically infected with hepatitis B virus (HBV). Many nail salon workers are at risk for HBV as they are coming from high-risk and traditionally underserved communities. To understand barriers and knowledge associated with HBV in the Vietnamese nail salon community, the Health Belief Model (HBM) was used to qualitatively assess the health needs for the prevention of HBV among Vietnamese nail salon workers in Philadelphia through focus groups and interviews (N = 19). Results revealed several themes that highlight barriers within the Vietnamese nail community. Major themes were the lack of knowledge related to hepatitis B, including significant misconceptions related to symptoms, and how hepatitis B is transmitted and prevented. There were also several barriers to health care access within the Vietnamese nail community including the cost of health care, long work hours, lack of insurance and lack of understanding of current community resources. Additionally, discrimination and stigma related to those infected with hepatitis B emerged as a theme from this data. Those interviewed also noted that the nail training and licensing they received did not highlight hepatitis B and other infectious diseases that can be spread within the nail salon.

RESUMEN

Liver cancer is the 3rd deadliest cancer worldwide, with 5-year survival rates of only 15%. In the United States, liver cancer incidence and death rates are increasing at a faster rate than any other cancer and are projected to continue to rise through at least 2030. A significant proportion of these liver cancer cases are due to hepatitis B virus (HBV). Community-based screening is a public health practice working to identify individuals who are living with HBV in underserved communities, particularly Asian American, Pacific Islander and African immigrant populations. This data set includes a total of 3019 individuals considered high risk for HBV tested at community-based testing events between 2008 and 2019. Descriptive results revealed HBV infection rate was 7.9% (N = 229), and 59% (N = 1704) had protective antibodies against HBV. To account for missingness in the data, multiple imputation was preformed and followed by logistic regression to create a predictive model. The results support an association between insurance status and HBV infection in the predictive model. Participant region of origin was also significantly related to HBV infection, and participants who immigrated from the Western Pacific and African World Organization designated regions had higher odds of infection compared to participants from the Americas. Results emphasize the need to continue to expand testing in high-risk populations for HBV.

RESUMEN

INTRODUCTION: Hepatitis delta virus (HDV) is a serious coinfection of the hepatitis B virus (HBV) that is estimated to affect between 48 to 72 million people worldwide. Data are limited on the informational needs of people living with HDV. The Hepatitis B Foundation, a US-based nonprofit organization that provides support to people living with HBV and HDV, receives emails (queries) as part of a helpline, a service to provide information, resources, and support to people affected by HBV and HDV. METHODS: Query content was analyzed to assess the impact of HDV at the individual level. A total of 65 HDV-related queries from 17 countries were received from October 2016 to January 2019, and all were analyzed for this study. RESULTS: Thematic analysis of queries indicated 4 dominant themes. Three were related to a need for information about 1) the disease and prevention of it, 2) disease symptoms and outcomes, and 3) treatment options. The fourth theme was related to barriers and quality of life. Individuals requested information on treatment options, medication access, diagnostic test interpretation, and clinical trials. CONCLUSION: Our study highlights the needs and lived experience of patients with HDV and summarizes critical information gaps. Findings can inform health care providers, public health professionals, and the pharmaceutical and biotechnology industries about the informational needs and lived experiences of individuals living with HDV and help create future HDV-related educational resources, care, and clinical trials.

RESUMEN

Chronic hepatitis B, a condition associated with severe complications, disproportionately affects Asian Americans and Pacific Islanders in the United States. Increasing testing among this population is critical for improving health outcomes. This study compares different types of video narratives that use storytelling techniques to an informational video (control), to examine whether narratives are associated with higher hepatitis B beliefs scores and video rating outcomes. A sample of Asian American and Pacific Islander adults (N = 600) completed an online survey where they viewed one of four video conditions, three of which included storytelling techniques and one with informational content. Results indicated that parental stories received significantly higher perceived effectiveness ratings (M = 3.88, SD = 0.61) than the older adult personal stories (M = 3.62, SD = 0.74), F(3, 596) = 3.795, p = .010. Parental stories also had significantly higher perceived severity scores (M = 3.83, SD = 0.69) compared to the young adult stories (M = 3.73, SD = 0.74) and the informational videos (M = 3.83, SD = 0.69), F(3, 596) = 7.72, p < .001. The informational videos (M = 4.10, SD = 0.65) received significantly higher message credibility ratings than the older adult personal stories (M = 3.84, SD = 0.70), F(3, 596) = 4.71, p = .003. Follow-up tests using Bonferroni correction revealed that parental stories (M = 3.98, SD = 0.64) and young adult personal stories (M = 3.934, SD = 0.76) scored significantly higher on speaker ratings than the older adult personal stories (M = 3.698, SD = 0.77). Results suggest that storytelling has the potential for connecting with a specific audience in an emotional way that is perceived well overall. Future research should examine the long-term impact of hepatitis B personal story videos and whether the addition of facts or statistics to videos would improve outcomes.

RESUMEN

Screening for hepatitis B (HBV) among high-risk young adults can help prevent its transmission and lead to earlier treatment and better long-term health outcomes. Yet few interventions have focused on increasing HBV awareness among young adults. Social media (SM) may be an effective method for disseminating information and engaging young adults about HBV. In this pilot study, qualitative and quantitative methods were applied to collect information on current use and perceptions toward SM through semistructured interviews and focus groups with young Chinese and Vietnamese adults and community leaders from local organizations in Philadelphia. Additionally, survey items were collected during the interviews and focus groups to provide quantitative data. Results from the interviews provided evidence that young adults and local organizations are already using SM and are open to using it to share general health information that is specific to their community. The focus groups suggested that using group pages or chats could be most appropriate for reaching young adults and that credible sources should be used to deliver messages that are tailored to the audience. The findings from this study will support the development of an SM intervention aimed at increasing HBV awareness.

RESUMEN

In the United States, Asian Americans account for 50-60% of hepatitis B virus infections, leading to higher rates of liver cancer in this population. While some city-wide data have reported hepatitis B infection rates among young adults as high as 10-20%, little research has examined factors that impact hepatitis B beliefs, or the most effective strategies for reaching this particular population to promote hepatitis B awareness. An online survey was conducted with young Asian American adults (n = 418), aged 18-29 years old, to better understand their health information seeking, social media usage, and hepatitis B-related behaviors and beliefs. Results indicated that doctors and health organizations were the most trusted sources of health information, while the Internet was the most common source of health information. The majority of participants (99.8%) reported using social media and indicated they engaged in health-related behaviors on social media. Several factors, including non-receipt of hepatitis B vaccine, engaging in more health-related social media activities, and a higher mean score for difficulty with health information seeking, were significantly related to higher perceived susceptibility to hepatitis B. Future research should explore the effectiveness of using social media to reach young Asian American adults to promote hepatitis B awareness.
