RESUMO

Chronic hepatitis B (CHB) is one of the most widespread liver diseases in the world. It is currently incurable and can lead to liver cirrhosis and cancer. The considerable impacts on society caused by CHB through patient mortality, morbidity, and economic loss are well-recognised in the field. This is, however, a narrow view of the harms, given that people living with CHB can be asymptomatic for the majority of their life-long infection. Of less-appreciated importance are the psychosocial harms, which can continue throughout an affected person's lifetime. Here we review the broad range of these impacts, which include fear and anxiety; financial loss and instability; stigma and discrimination; and rejection by society. Importantly, these directly affect patient diagnosis, management, and treatment. Further, we highlight the roles that the research community can play in taking these factors into account and mitigating them. In particular, the development of a cure for hepatitis B virus infection would alleviate many of the psychosocial impacts of CHB. We conclude that there should be a greater recognition of the full impacts associated with CHB to bring meaningful, effective, and deliverable results to the global community living with hepatitis B.

RESUMO

Chronic hepatitis B virus (HBV) infection is a global public health challenge on the same scale as tuberculosis, HIV, and malaria. The International Coalition to Eliminate HBV (ICE-HBV) is a coalition of experts dedicated to accelerating the discovery of a cure for chronic hepatitis B. Following extensive consultation with more than 50 scientists from across the globe, as well as key stakeholders including people affected by HBV, we have identified gaps in our current knowledge and new strategies and tools that are required to achieve HBV cure. We believe that research must focus on the discovery of interventional strategies that will permanently reduce the number of productively infected cells or permanently silence the covalently closed circular DNA in those cells, and that will stimulate HBV-specific host immune responses which mimic spontaneous resolution of HBV infection. There is also a pressing need for the establishment of repositories of standardised HBV reagents and protocols that can be accessed by all HBV researchers throughout the world. The HBV cure research agenda outlined in this position paper will contribute markedly to the goal of eliminating HBV infection worldwide.

RESUMO

The "Know Hepatitis B" campaign was the first national, multilingual communications campaign to promote testing for hepatitis B virus (HBV) among Asian Americans and Pacific Islanders (AAPIs). This population comprises fewer than 5% of the total U.S. population but accounts for more than half of the up to 1.4 million Americans living with chronic HBV infection. To address this health disparity with a national campaign, CDC partnered with Hep B United, a national coalition of community-based partners working to educate AAPIs about hepatitis B and the need for testing. Guided by formative research, the "Know Hepatitis B" campaign was implemented in 2013 with a two-pronged communications strategy. CDC used available Chinese, Korean, and Vietnamese media outlets on a national level and relied on Hep B United to incorporate campaign materials into educational efforts at the local level. This partnership helped facilitate HBV testing among the priority population.

RESUMO

The global burden of hepatocellular carcinoma (HCC; primary liver cancer) is increasing. HCC is often unaccompanied by clear symptomatology, causing patients to be unaware of their disease. Moreover, effective treatment for those with advanced disease is lacking. As such, effective surveillance and early detection of HCC are essential. However, current screening and surveillance guidelines are not being fully implemented. Some at-risk populations fall outside of the guidelines, and patients who are screened are often not diagnosed at an early enough stage for treatment to be effective. From March 17 to 19, 2015, the Hepatitis B Foundation sponsored a workshop to identify gaps and limitations in current approaches to the detection and treatment of HCC and to define research priorities and opportunities for advocacy. In this Commentary, we summarize areas for further research and action that were discussed throughout the workshop to improve the recognition of liver disease generally, improve the recognition of liver cancer risk, and improve the recognition that screening for HCC makes a life-saving difference. Participants agreed that primary prevention of HCC relies on prevention and treatment of viral hepatitis and other underlying etiologies. Earlier diagnosis (secondary prevention) needs to be substantially improved. Areas for attention include increasing practitioner awareness, better definition of at-risk populations, and improved performance of screening approaches (ultrasound, biomarkers for detection, risk stratification, targeted therapies). The heterogeneous nature of HCC makes it unlikely that a single therapeutic agent will be universally effective. Medical management will benefit from the development of new, targeted treatment approaches.

RESUMO

BACKGROUND: This article describes hepatitis B-related knowledge, attitudes and practices after completion of the Gateway to Care campaign, a citywide public health education program that targeted city residents, health care providers and individuals chronically infected with hepatitis B virus in Haimen City, China. METHODS: Pre/post questionnaires assessed hepatitis B knowledge change among health care providers and post-campaign surveys evaluated hepatitis B knowledge, attitudes and behaviors (including stigma-related beliefs and practices) among health care providers, city residents and chronically infected individuals. Focus groups were conducted to gain a more in-depth understanding of the needs of the target communities, and to identify future intervention strategies to improve hepatitis B testing and linkage to care and treatment. RESULTS: Results indicate high levels of hepatitis B knowledge among multiple stakeholders in Haimen City, with significant knowledge improvement among health care providers. Stigma-related beliefs and myths regarding separation of infected individuals from certain aspects of family life were common among all stakeholder groups, despite high levels of accurate knowledge about hepatitis B transmission and prevention. Self-report of hepatitis B screening was low among city residents, as was awareness of hepatitis B treatment. CONCLUSIONS: More efforts are needed to improve awareness of HBV treatment, decrease HBV-related stigma, improve screening rates, and reduce cost of antiviral treatment. Future interventions in Haimen City should be driven by behavioral change theory, to not only improve knowledge, but to improve screening behaviors and address hepatitis B-related stigma and discrimination.

RESUMO

In regions where hepatitis B virus (HBV) is endemic, perinatal transmission is common. Infected newborns have a 90% chance of developing chronic HBV infection, and 1 in 4 will die prematurely from HBV-related liver disease. In 2010, the Hepatitis B Foundation and the Haimen City CDC launched the Gateway to Care campaign in Haimen City, China to improve awareness, prevention, and control of HBV infection citywide. The campaign included efforts to prevent perinatal HBV transmission by screening all pregnant women for hepatitis B surface antigen (HBsAg), following those who tested positive, and administering immunoprophylaxis to their newborns at birth. Of 5407 pregnant women screened, 185 were confirmed HBsAg-positive and followed until delivery. At age one, 175 babies were available for follow up testing. Of those, 137 tested negative for HBsAg and positive for antibodies to HBsAg, indicating protection. An additional 34 HBsAg-negative babies also tested negative for antibodies to HBsAg or had indeterminate test results, were considered to have had inadequate immune responses to the vaccine, and were given a booster dose. A higher prevalence of nonresponse to HBV vaccine was observed among babies born to hepatitis B e antigen (HBeAg)-positive mothers and mothers with high HBV DNA titers. The remaining 4 babies tested positive for HBsAg and negative for antibodies, indicative of active HBV infection. The mothers of all 4 had viral loads ≥8×10(6) copies/ml in the third trimester. Although inadequate response or nonresponse to HBV vaccine was more common among babies born to HBeAg-positive and/or high viral load mothers, these risk factors did not completely predict nonresponsiveness. All babies born to HBV-infected mothers should be tested upon completion of the vaccine series to ascertain adequate protection. Some babies of HBeAg-positive mothers with high viral load may still become HBV infected despite timely immunoprophylaxis with HBV vaccine and HBIG.

RESUMO

BACKGROUND: An estimated one million people worldwide die each year from complications of chronic hepatitis B infection (CHB), including liver cancer. A disproportionate number of infections and deaths occur in China. The incidence and mortality of liver cancer in Haimen City is among the highest in China, and in the world. A multi-year citywide campaign was aimed at eliminating hepatitis B virus (HBV) infection and significantly reducing the number of liver cancer deaths due to CHB in Haimen City, China. METHODS: Strategies included a public health information campaign targeting the 1.03 million city residents; specialized health education for leaders and providers to increase adoption of evidence-based HBV management protocols; establishment of health care infrastructure and management systems; and increased prevention and care delivery to key subpopulations (especially pregnant women). RESULTS: The project developed and deployed broad-reaching public awareness and health education tools and modules to 280,000 households and at community-based events. More than 90% of targeted healthcare providers and 80% of the community leaders/government officials attended educational seminars during the project period (1,441 health care providers; 1,883 local government officials). A centralized registration and management system for pregnant women was developed and instituted, 100% of pregnant women were enrolled (5,407 women over one year), and all infants born to HBV-infected mothers received one dose of HBIG and the first dose of HBV vaccine by 24 hours of birth. CONCLUSIONS: Lessons from the implementation phase of the project include the importance of: gaining early and ongoing support from the local government and health bureau for success in reaching the targeted populations; and having project management by a local, experienced, and trusted health expert to navigate implementation and relationships, and help develop culturally and linguistically appropriate materials.

RESUMO

Infection with the hepatitis B virus (HBV) is a significant public health concern in the US, disproportionately affecting Americans of Asian, Native Hawaiian and Pacific Islander descent, despite the availability of a simple blood test, approved treatments, and an effective vaccine. Hep B United, a national campaign to support and leverage the success of community-based HBV coalitions, convened a partner summit in 2012 to develop a strategic response to the HHS Action Plan for the Prevention, Care, and Treatment of Viral Hepatitis. The resulting community action plan focuses on advancing three areas of the HHS plan: educating providers and communities to reduce health disparities; improving testing and linkage to care to prevent HBV-related liver disease and cancer; and eliminating perinatal HBV transmission.

RESUMO

Chronic infection with the hepatitis B virus can lead to hepatocellular carcinoma and cirrhosis in up to 25% of infected individuals. As many as 2 million individuals in the US may have chronic hepatitis B infection, most of whom immigrated to the US from hepatitis B-endemic regions of the world. A 2010 report from the Institute of Medicine noted that two thirds of patients with hepatitis B are unaware of their infection, and most health care providers do not screen for hepatitis B or know how to manage hepatitis B-positive patients. In 2010, the Hepatitis B Foundation convened a group of primary care providers to consider the existing evidenced-based recommendations and strategies for implementation of hepatitis B screening into routine practice. The group designed an easy-to-use algorithm for screening, initial evaluation, ongoing management, and referral to a subspecialist when appropriate. Internal medicine specialists, including primary care providers and subspecialists, need to understand the steps they can take to address this often under-recognized disorder.

RESUMO

Chronic hepatitis B virus (HBV) infection in children presents a therapeutic challenge for the practitioner. Decisions regarding selection of patients who may benefit from treatment, appropriate timing of treatment, and the choice of antiviral therapy are complex and are compounded by the limited number of drugs that have been studied in children. An expert panel of nationally recognized pediatric liver specialists was convened by the Hepatitis B Foundation on August 11, 2009, to consider clinical practice relative to the therapeutic options available for children. A detailed account of these discussions is provided, and the opinions expressed are based on consensus of the experts, as well as on published evidence when available. The panel concludes that, at this time, there is no established benefit of treatment of children in the immune tolerant phase, and there is a very high risk of development of drug resistance. In addition, there is no indication for treatment of children in the inactive carrier state. For children in the immune active or reactivation phases, liver histology can help guide treatment decisions, and family history of liver disease, especially hepatocellular carcinoma, may argue for early treatment in some cases. Outside of clinical trials, interferon is the agent of choice in most cases. Nucleos(t)ide analogues are secondary therapies, and children who receive these agents require careful monitoring for development of resistance. There are a few situations when treatment is indicated regardless of HBV DNA or alanine aminotransferase levels. There is still much to be elucidated about the appropriate use of HBV therapy in children. Until more clinical data and therapeutic options are available, a conservative approach is warranted.

RESUMO

Most children with chronic hepatitis B virus infection (persistent hepatitis B surface antigen-positive for >6 months) are asymptomatic and do not generally require treatment. These children are, however, at increased risk for severe complications later in life, including advanced liver disease and liver cancer. On November 11, 2008, the Hepatitis B Foundation, a nonprofit research and disease advocacy organization, convened a panel of nationally recognized North American pediatric liver specialists to consider and recommend an approach for the screening, monitoring, initial management, and referral of children with chronic hepatitis B. The panel developed recommendations to provide guidance to practitioners on determining what additional tests to conduct, how often to monitor on the basis of test results, and when to refer to a pediatric liver specialist to build a partnership between the practitioner and liver specialist to enhance the success of management of children with this lifelong infection.
