Breaking barriers and improving outcomes: Overcoming challenges in hepatitis B and delta screening, prevention and linkage to care among people who use drugs in Philadelphia

Little is known about the prevalence of hepatitis B and delta viruses (HBV/HDV) among people who use drugs (PWUD). Despite being a high-risk population, awareness of these viruses is still low among both community members and healthcare providers. Two recent studies conducted in Philadelphia, which were led by the Hepatitis B Foundation in partnership with Prevention Point Philadelphia, highlight different aspects of this ongoing public health concern. The first identified barriers to screening, prevention and linkage to care, while the other aimed to dismantle those barriers.

The first study explored the obstacles to HBV and HDV prevention, diagnosis and follow-up care. The study evaluated current knowledge levels and identified the needs and preferences of both people who use drugs and providers that serve them. Data was collected through an anonymous online provider-focused survey, and interviews were conducted with community members, and both medical and non-medical staff from different harm reduction settings in Philadelphia, Pennsylvania.

Interviews with key informants revealed that:

  • 48% of interviewed providers reported confusion about insurance coverage as a barrier to HBV screening.
  • 45% of providers mentioned the need to address and prioritize other pressing health needs, as a challenge to conducting HBV screening.
  • 52% of providers noted patient hesitancy as a barrier to HBV vaccination.
  • 39% of providers identified the need to administer multiple doses as a challenge for completing the HBV vaccination series.
  • 62% of providers reported low knowledge of HDV tests as a barrier to HDV testing.
  • 31% of providers indicated complexity of guidelines as a challenge in HDV testing.

Overall, awareness of HBV and HDV in the community, and among staff and health care workers was low, and stigma related to drug use and harm reduction was a significant barrier to care. There is an urgent need to address this issue in a non-judgemental and non-stigmatizing way that is clear, factual and empowering. Continued financial and political support for harm reduction organizations is essential for improving health care access for people who use drugs. More efforts are needed to overcome barriers to vaccination, testing and linkage to care to create better health outcomes and ultimately increase the quality of life of people who use drugs. 

The second study aimed to assess the prevalence of HBV and HDV and enhance access to care among people who use drugs, through a harm reduction organization (HRO) in Philadelphia. Participants first completed a demographic survey to help researchers gather information about their backgrounds and lifestyles, and to improve understanding of HBV and HDV risk factors within the community. Participants were then screened for HBV, and if they tested positive for certain HBV markers, they were automatically tested for hepatitis delta. 

Of the 498 participants:

  • 25.3% did not have hepatitis B immunity.
  • 52.6% had been vaccinated against HBV.
  • 17.9% had recovered from a past HBV infection.
  • 2.2% tested positive for isolated HBV core antibody.
  • 2.0% tested positive for HBV surface antigen.
  • 0.2% tested positive for HDV antibody.
  • 10% of those who were living with an active HBV infection had an HBV/HDV coinfection.

This study found that rates of current HBV infection in this community were nearly three times greater than in the general U.S. population, and the 10% coinfection rate of HDV is also significantly higher. Risk factors associated with a positive HBV status included a history of incarceration, experiences with homelessness and transactional sexual encounters. These findings highlight the prevalence of hepatitis B and D in this population. These viruses pose serious and critical public health concerns and remain under-prioritized among people who use drugs. Consistent and robust screening, vaccination, and linkage to care efforts can positively impact health outcomes for this community. Approving a hepatitis B point-of-care test (so that people who get tested can get results almost immediately), support in the form of funding and policy to allow HROs to provide full healthcare services, and adequate insurance coverage for vaccines can contribute to positive outcomes for hepatitis B and D diagnosis, prevention and treatment. These recommendations can advance elimination efforts, lower mortality, increase quality of life and center the health and needs of people who use drugs.

CHIPO Member Highlight: Africa Health Research Institute

The Coalition against Hepatitis for People of African Origin (CHIPO) is a community coalition co-founded and led by the Hepatitis B Foundation. We are composed of organizations and individuals interested in addressing the high rates of hepatitis B infection among African communities around the world. CHIPO serves as a forum for sharing information and best practices and increasing national and global capacity to improve hepatitis B awareness, testing, vaccination and treatment among highly affected African communities.

This month, CHIPO interviewed member organization, the Africa Health Research Institute in South Africa about their mission, work, and goals, especially related to hepatitis B. Read on to learn more about the great work of this organization!

  1. Could you please introduce yourself and your organization?

I’m Dr. Janine Upton, currently a Project Manager within the discipline of implementation science at the Africa Health Research Institute (AHRI), Durban KwaZulu Natal, South Africa.

AHRI is an independent, transdisciplinary scientific research institute based across two campuses in the province of KwaZulu-Natal (KZN) in South Africa. AHRI’s research combines population, basic and translational, social, implementation and clinical sciences to understand and intervene in the health and well-being of South African communities. AHRI works in partnership with local communities and South African academic, governmental, and other policy stakeholders, and collaborates with over 60 institutions globally. AHRI prioritizes the training of the next generation of African scientists. The work of AHRI’s ~700 scientists, students and staff members is driven by the values of ubuntu, transformation, leadership, innovation, excellence and collaboration.

  1. Could you tell me a little bit more about your organization’s programs and campaigns?

AHRI actively drives an HIV/TB/Emerging Infections (like COVID and Mpox) program, and more recently an HBV agenda, partnering with media outlets (TV/radio), the Department of Health (DoH), schools, the Department of Agriculture (DoA), local municipalities, and South African Police Services (SAPS), amongst others, to educate and raise awareness of these diseases within the populations most affected by them. More specifically, AHRI has recently put hepatitis on its strategic map by establishing the study entitled “Evaluation of Vukuzazi LiVEr disease – Hepatitis B: A study to determine the prevalence and characteristics of chronic hepatitis B virus infection in the Vukuzazi population to inform interventions for diagnosis, treatment and prevention” (EVoLVE). See our website for more details: EVoLVE Hepatitis B Study – Africa Health Research Institute (ahri.org)

EVoLVE aims to address the pressing need to develop insights into local population HBV epidemiology (considering vaccination, exposure and infection), to quantify the need for – and potential impact of – antiviral treatment. EVoLVE also aims to enhance local pathways for the assessment and provision of clinical care to people living with HBV infection in South Africa. Data collected as part of an interdisciplinary collaboration between clinical and social scientists, in consultation with communities, will be used to inform responsive and sensitive-to-context interventions specifically targeting those at greatest risk of infection and disease, and provide clinical care, support and education, whilst developing an evidence-based foundation for future studies.

EVoLVE has already celebrated a successful collaboration between the clinical and human sciences by involving a Community Advisory Board (CAB) in the inductive development of community understanding and perceptions pertaining to the hepatitis B virus (HBV).  In January 2024, the AHRI EVoLVE Team participated in a community engagement with the AHRI CAB and conducted FibroScan training with AHRI clinical and research teams. (FibroScan is a non-invasive ultrasound that measures liver stiffness and fat content to help determine the health of your liver.)

  1. What are some challenges that you face in addressing hepatitis, how have you worked to overcome these? Are there any additional resources that would be helpful to have?

Poor community knowledge, awareness and applicability of HBV

The knowledge of HBV within communities was reported to be very limited and as a result, it is not perceived as a local concern. Poor screening and limited knowledge of prevention methods are other major barriers. Liver disease was not seen as synonymous with HBV, and there was an absence of any isiZulu (indigenous language term) for hepatitis B. Whilst participants were aware of liver disease, they lacked specific knowledge about HBV infection, often misattributing liver disease to alcohol use, traditional medicines, or poor adherence to ART (antiretroviral therapy, typically used to treat HIV infection). Liver disease was perceived to be a “white or rich person’s” disease, and subsequently not a community health concern.

Stigma and discrimination

Stigma and discrimination are a challenge as participants associated the symptoms of liver disease as synonymous with untreated HIV infection, which remains highly stigmatized in South African society. This often resulted in the loss of connections and the withdrawal of social support from families and communities. Caregivers, family members or other members of the community also experienced discrimination when trying to support someone suffering with liver disease. Additionally, participants described negative healthcare experiences, feeling dismissed and ignored by health care workers.

Inequitable access to healthcare

For people living with hepatitis B (PLWHB) who are advised to undergo long-term treatment, adherence presents a significant challenge, particularly for those experiencing food insecurity. These individuals often face the dilemma of prioritising feeding their families over covering the costs associated with treatment. Even when medication is provided at no cost, additional expenses such as transportation to healthcare facilities and time away from other responsibilities create financial burdens that are difficult to manage. As a result, many individuals become discouraged and instead seek support from traditional healers, who are more accessible within their communities.

In terms of additional resources, we were able to secure a small project grant from University College London, called ‘Grand Challenges,’ but longer-term funding will be needed to build on these foundations.

  1. What do you think are some of the biggest barriers against raising awareness and addressing rates of hepatitis screening and linkage to care at the local and national levels, and what more do you think can be done in this sphere of awareness building?

There is an urgent need to identify social and psychological barriers to treatment adherence and develop strategies to overcome them, whilst concurrently adopting a social and medical focus on the identification of the determinants of health. In so doing, strengthening messaging and information available for the uptake of communities and empowering individuals and communities to improve health outcomes and reduce HBV transmission is critical. The hope is to at the same time address the misconceptions around the disease and reduce the stigma and taboo that occur within the silence surrounding the topic. This will assist in the scaling up of resources required to promote knowledge of the disease in communities, and encourage support systems necessary to improve mental health and treatment outcomes.

  1. What are your favorite parts about your job and what got you interested in this work?

I love the problem-solving that comes with my job – that people can come to me with novel and ever-changing requests and challenges to which I can apply my mind. Essentially – that is research! It’s identifying a real-world problem and applying your mind in finding solutions! I feel like the nature of the work we do at AHRI is meaningful and seeing this reflected in longitudinal data is truly rewarding. I love the field of health, it’s always been a passion of mine, so being able to combine a passion with a strength in enriching ways is fulfilling to me!

Highlighting the Relationship between Hepatitis B and Liver Cancer

Highlighting the Relationship between hepatitis B and Liver Cancer

October marks Liver Cancer Awareness Month, an initiative highlighting this significant, but under-prioritized public health concern. Unfortunately, people living with hepatitis B have greater risk of developing liver cancer, and this risk is even higher for people born in countries where hepatitis B is more prevalent (Department of Health and Human Services [HHS], 2014; Chayanupatkul et al., 2017). Because of this, the Hepatitis B Foundation (HBF) conducted a study among foreign-born communities in the U.S. who are heavily impacted by the hepatitis B virus (HBV) to assess awareness levels about the connection between HBV and liver cancer. HBF used the perspectives and ideas expressed during these focus groups to create culturally and linguistically tailored, community-focused awareness and educational materials, so that everyone has continuous access to user-friendly HBV and liver cancer information.

From April to September 2021, the HBF conducted focus groups with people from the Micronesian, Chinese, Hmong, Nigerian, Ghanaian, Vietnamese, Korean, Somali, Ethiopian, Filipino, Haitian, and Francophone West African communities. A total of 15 virtual focus groups took place, with 101 individuals providing their thoughts about what hepatitis B and liver cancer are, and insights into appropriate strategies to educate their greater communities on the connection between these two conditions. The resulting communications campaign aims to improve the public’s knowledge about the link between HBV and liver cancer, reduce hepatitis B- and liver cancer-related myths and misconceptions, and promote hepatitis B and liver cancer screening and early detection among Asian and Pacific Islander (API) and African and Caribbean immigrant communities. The ideas and experiences voiced by focus group participants also contributed to the development of informational liver cancer materials for community health educators to integrate into existing education programs for immigrant communities.

Summary of focus group findings:

All focus groups emphasized the need for educational materials to highlight the relationship between hepatitis B and liver cancer. Interestingly, people were more aware of liver cancer and its serious health consequences than they were of hepatitis B and how it is a leading cause of liver cancer. Many people had personal experience with liver cancer, having known family members, friends or other community members who have died from the disease. With this, participants believed that people will be more likely to practice healthy behaviors, like vaccination and routine screening, when they know that HBV can lead to liver cancer and know what behaviors can reduce their risk of liver cancer and death. When people learn about the benefits of vaccination (like full protection against HBV and reducing the risk of transmitting the virus to loved ones), and screening (keeping your liver healthy), and are provided with resources and tools to manage their health, they are empowered and are more likely to make healthy choices to reduce their risk of severe health outcomes.

When educating people about the connection between the two diseases, it is also important to address the widespread misconceptions about both hepatitis B and liver cancer, which contribute to shame and stigma surrounding each condition. Many focus group participants revealed that their communities believe that HBV is related exclusively to sexual promiscuity, injection drug use and poor hygiene, all of which lead to stigma against people living with hepatitis B (PLHB), who are believed to be “immoral” or “dirty.” These stigmatizing beliefs cause PLHB to become reluctant to seek care and treatment for the virus, and can discourage screening in the greater community because people do not want to be shamed by or isolated from their social circles. Additionally, participants discussed how their communities believe that liver cancer is only associated with alcohol and are unaware of the causal relationship between HBV and liver cancer. According to focus group participants, educational materials should include some information about how hepatitis B is transmitted and how it can lead to liver cancer if left untreated and unmanaged. One way to do this is by including the personal testimonials of PLHB and liver cancer in educational materials, who show the audience how they stay healthy and maintain a good quality of life while living with these diseases. As people see how one’s quality of life does not diminish, and learn from the stories of people living with hepatitis B or liver cancer, they may become more understanding of the diseases and supportive of their own community members who are living with them.

Focus group participants were also asked to identify communication strategies that would be acceptable for their community groups. As for in-person communication, educational sessions should take place in settings where people feel safe, including community-based organizations, religious spaces, and healthcare offices. These sessions, as emphasized by participants, should be facilitated by trusted messengers, like patient navigators, doctors, and faith leaders, or other people who have a shared culture with the audience. Demonstrating cultural respect during face-to-face communication is also of utmost importance. Certain communities emphasized that it is especially important to have gender-specific messengers when discussing topics like sexual transmission of hepatitis B (Taylor et al., 2013; Cudjoe et al., 2021). 

Educational campaigns should also be strategic when discussing community-specific risk, as it is important to discuss each community’s risk without placing blame on a specific group. Despite the fact that countries in the Asian-Pacific and sub-Saharan African regions have endemic levels of HBV and the highest global incidence rates of liver cancer (Zamor et al., 2017), many focus groups explained that their communities consider HBV and liver cancer to be Western diseases, since the conditions are often not discussed in home countries, and are therefore unaware of both the severity of the diseases and their personal risk. Focus group participants agreed that informational material can group highly impacted communities together when presenting prevalence rates and risk factors, so as to reduce shame associated with HBV and liver cancer of one group while increasing audience awareness of their risk (Parvanta & Bass, 2018). 

Experiences of Community Focus Group Facilitators

Community participation and leadership was of utmost importance in this project. Two focus group facilitators recounted their experiences of recruiting and conducting focus groups with their communities. The first was the leader of the Cantonese focus group.

Despite being nervous about how it would turn out, one facilitator spent time thinking about the project. They chose to conduct the focus group in Chinese (Cantonese), the “native language of the participants,” and hoped that communicating in Cantonese would increase participant engagement, especially when discussing their “lived experience of the disease.” 

“Prior to convening the Zoom meeting, I had provided a one-on-one orientation to each participant about the theme of the focus group and expectations. As a result, everyone was ready and able to fully participate, and speak openly at the meeting. It was a fruitful discussion among the five participants. Everyone brought up their perspectives and insights about stigma and health education strategies to the community. They had expressed a sense of fear and emotional distress when they were made aware of the relationship between hepatitis B and liver cancer. They raised lots of questions on hepatitis B transmission, testing and vaccination, and liver cancer and treatment, and were very interested to learn more about necessary lifestyle changes if they contracted chronic hepatitis B. 

At the end participants had requested a follow-up session to learn more about HBV and liver cancer.  They will be excited to know about the release of the newly developed Chinese-language educational materials on both diseases, which came together because of their contributions. I would suggest Hepatitis B Foundation and UC Davis to host an in-person workshop to present  the new education materials.  That would be a meaningful outreach and education to the local Chinese and Asian communities.”

Another facilitator shared their thoughts and insights regarding the focus group they conducted with their African immigrant community. They felt that being a facilitator for this study was an “enlightening experience,” especially as they uncovered their community’s healthcare awareness as it relates to hepatitis B and liver cancer. They continued to share:

“Running the focus group gave me valuable insights into the knowledge gaps and misconceptions surrounding HBV within the African immigrant population. Through open and honest discussions, we uncovered specific areas where education and awareness initiatives can have a significant impact. Many participants needed to understand the transmission, prevention, and available resources related to these diseases. Understanding these nuances is crucial in tailoring our educational materials effectively.

Regarding the study findings, it was evident that there is a pressing need for culturally sensitive educational resources. The unique challenges African immigrants face, including language barriers and cultural differences, highlight the importance of creating materials that resonate with our community members. Moreover, the findings emphasized the urgency of dispelling myths and stigmas associated with HBV and fostering a supportive environment for affected individuals and their families.

As for the materials produced for the campaign, I am genuinely impressed with the effort and attention to detail put into their creation. The content is informative and culturally relevant, making it relatable to our community. Using images, culturally familiar scenarios, and visuals ensures that these materials will significantly raise awareness about HBV in my community.

When disseminated effectively, these materials will empower African immigrants with the knowledge they need to protect themselves and their loved ones. By addressing the specific concerns and questions raised during our focus group sessions, these resources have the potential to bridge the information gap and promote proactive healthcare practices within our community.”

Conclusion

The overall goals of these materials are to facilitate improved hepatitis B and liver cancer awareness, increase testing and prevention behaviors, and reduce misconceptions about the two diseases to ultimately reduce HBV- and liver cancer-related death. Thanks to the insights and recommendations from the focus group participants, educational hepatitis B and liver cancer materials were created in a culturally sensitive and linguistically appropriate manner for a number of communities in the U.S. who are greatly impacted by the two diseases. To reach a broad audience, the materials will be available on multiple communication platforms and in multiple languages. This first part of the community-informed educational campaign can be found on the HBF’s Liver Cancer Connect website now. All materials will be fully uploaded and available to the public for further community education starting in February of 2024. Translated materials and messages tailored for audio and video formats will also be uploaded on a rolling basis.

Podcast Recap: How Clinical Trials Work in the United States

 

 

 

 

 

 

 

 

 

 

 

 

 

In a recent B Heppy episode on clinical trials, Dr. Yasmin Ibrahim, Public Health Program Director at the Hepatitis B Foundation, discussed the process of how clinical trials work and the importance of clinical research in moving forward public health programs and interventions. 

What is a Clinical Trial? 

A clinical trial (also called clinical research) is the process for approving new medications or devices for a known health condition or disease. When people hear the term clinical trial, they may hink immediately that participants of that trial are at risk. What most don’t know is that before a medication or medical device is tested on human beings, it must go through a very rigorous process with approval from regulatory authorities and agencies. This is why clinical trials go through phases of approval and safety checks in the research process. We have outlined the phases of clinical trials below to help provide an understanding of the process.  

Pre-clinical or lab studies: Before the drug can be tested on human beings, it is thoroughly researched on living cells and then animals with similar biological makeup, to assess its efficacy (benefits) and safety. 

Clinical Phase I: Researchers test a new drug or treatment on a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify any side effects. 

Clinical Phase II: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety. 

Clinical Phase III: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely. 

Clinical Phase IV: Studies are done after the drug or treatment has been marketed to gather information on the drug’s effect in many different populations and determine any side effects associated with long-term use of the product or drug. 

All new treatments must go through clinical trials before being approved for use by the United States Food and Drug Administration (FDA), European Medicine Agency (EMA) or any other local regulatory authorities depending on the country.   

Advancing and Sustaining Public Health through Research 

Clinical trials are important because they are the safest way to develop and discover new treatments that work to cure diseases or improve the health and quality of life of patients. Because clinical trials have very strict safety regulations, they also tell us if a treatment is safe for people to use.  

Eligibility Criteria for Participation in Clinical Trials  

Eligibility criteria for clinical trials depends on the type of research being conducted. If a vaccine is being tested, then most participants are healthy to assess the response of the vaccine on the body’s immune system and the ability to produce protective antibodies. In some clinical trials that focus on certain populations or multiple conditions, the criteria may be more specific (e.g., testing the HBV treatments on people living with hepatitis B and diabetes). Study design and objectives determine participant eligibility and criteria. 

Diversity and Inclusivity in Clinical Trials 

Historically, clinical trials have neglected participation from minority populations and under-served communities. For example, sub-Saharan Africa has one of the highest burdens of hepatitis B globally, but clinical trials for hepatitis B are inadequate in those areas. The people who need access to clinical research the most are often denied access to these opportunities due to geographical barriers, lack of political will, regulatory issues, and other logistical challenges. It is important to ensure that all people who are directly impacted by hepatitis B should have access to participating in clinical trials and affording innovative therapies to improve their quality of life. There are steps that pharmaceutical and biotech companies, medical researchers, and public health organizations can take to diversify participation in clinical research. This involves including local patient-centered organizations and patient advocates in the clinical trial participation recruiting process. Partnering with a community is a helpful strategy to build trust with the community and engage people in research. Communication is integral to ensuring that participants fully understand the extent of their participation and the goals behind the research. Participants are encouraged to ask questions from the recruiters before agreeing to participate in the research.

Podcast Recap: Current Treatments in Development for Hepatitis B with Dr. John Tavis

 

 

 

 

 

 

 

 

 

 

 

 

In a recent B Heppy episode, Dr. John Tavis, a molecular microbiologist at St. Louis University School of Medicine, shared updates on curative therapies for hepatitis B along with insights on how treatments for hepatitis B are researched and approved for use. 

Hepatitis B is a virus that can cause serious liver disease such as liver cancer or liver failure if undiagnosed, unmanaged or without proper intervention and treatment. While there is no cure for hepatitis B at this time, there are treatment options available to manage the virus. Research to find an optimal and functional cure for hepatitis B is ongoing and clinical trials have been very successful in advancing research pertaining to the cure.  

In some experimental studies conducted around the globe, 30% to 40% of patients have achieved functional cure. In smaller studies, approximately 50% of patients have obtained functional cure. However, research on the cure and the progression of these clinical interventions are still ongoing. While the future looks promising for a functional cure for hepatitis B, existing treatments should not be undermined or overlooked as they provide effective protection from serious liver disease such as cirrhosis or liver cancer.  

There are key terms that are important to understand related to drug development and the hepatitis B space. Below we describe complete, functional and partial cure definitions according to researchers.  

Complete, Functional, and Partial Cure 

Complete Cure: Elimination of all traces of hepatitis B including loss of surface antigen and HBV DNA. 

Functional Cure: the loss of hepatitis B surface antigen and undetectable HBV DNA levels, although trace amounts of HBV DNA may persist in the liver.  

Partial Cure: A stable suppression of the virus with undetectable HBV DNA levels. 

The progress on the cure: 

Current progress and research indicate that a combination of drugs will provide the best outcome as it is not likely that only one drug will achieve a functional cure for hepatitis B at this time. There are different types of drugs that are being studied and each treatment focus on a different aspect of the lifecycle of the virus to prevent replication and growth.  

Some of the current options being studied for hepatitis B treatment include: 

Antisense RNA and SiRNA: These drugs work by suppressing and destroying the viral messenger RNA, which is crucial to make proteins and replicate HBV DNA. Current drugs that use this mechanism to target the virus include Bepirovirsen. Clinical trials have shown effective reduction in HBV DNA and viral proteins.  

Suppressing and destroying the viral RNA (destroys proteins—RNA makes proteins,  

CAMs (capsid assembly modifiers): These drugs work by disrupting the formation of capsids. Capsids provide a protective space for the genetic material of the virus to make sure it is able to transfer to the host cell without any complications. By disrupting the formation of the capsids, the virus is unable to replicate itself as the genetic material gets destroyed during the process.  

NAPs (Nucleic Acid Polymers): These drugs work by blocking secretion of the viral surface antigen outside of the cells so the virus is unable to spread to other cells. In the process, the surface antigen drops in the bloodstream and the immune system is alerted to attack the virus.  

Nucleotide Analogues: These drugs are the first-line treatments for hepatitis B. Antiviral treatments like entecavir and tenofovir are incredibly effective in suppressing HBV viremia and preventing progression of the virus from becoming cancerous. Although they are not considered functional cure, these drugs have low toxicity and are effective in treating people living with hepatitis B.

If You Have Hepatitis B, Donating Your Blood May Change the Face of Hepatitis B Testing.

The Hepatitis B Foundation has partnered with Plasma Services Group to educate people living with Hepatitis B about the critical need for blood donation. This is not like the local blood drives you always hear about. Instead, Plasma Services Group focuses on specialty plasma collection which supports the making of diagnostic tests used in labs around the world. The demand for HBV testing grows every year, but access to those tests is not assured. As you know, only 25% of people in the U.S. and 10% of people worldwide with Hepatitis B have been diagnosed. With your help, we can reduce those real-life barriers to Hepatitis B testing and improve lives. Follow the link.

How do I donate?

Donating your blood to Plasma Services Group is easy. After you complete this form, they will reach out to you if you are a good candidate for blood donation. If chosen, they will send a phlebotomist to your home to complete the blood-draw.  PSG compensates participants financially as a thank you for the trust, time and efforts associated with donation. This program is only available to U.S. residents who are preferably in the Northeast. You must be 18 years of age or older and weight 110 pounds or more. You must be living with chronic Hepatitis B, which means you have had Hepatitis B for over 6 months.

Why this is important to the future of Hepatitis B?

As you may know, access to good healthcare isn’t always easy. By creating new blood tests, we can help diagnose Hepatitis B more reliably which helps more people get into care and manage their hepatitis B. Your blood donation could directly impact the detection, care and quality of life for millions of people living with hepatitis B who have not been diagnosed yet, as well as those who are managing their care on a daily basis.

Despite the large population of people living with hepatitis B, it is hard for companies that source biological raw materials to recruit donors. Most people are unaware of the large amount of blood plasmas that are essential to manufacture test kits. Rarer subtypes that are prevalent in Africa and Asia, where the need for detection is the highest and growing the fastest, are even harder to find in N. America. By becoming a regular donor to Plasma Services Group, you are filling a vital role for the medical diagnostic industry and helping to close the gap between patient and care.

Reactivation with Hepatitis B: Understanding Risk Factors and Prevention Strategies

Understanding the hepatitis B virus and the panel of blood tests needed to determine infection or immunity can be a stressful and challenging task. In simplest terms, “hepatitis” means liver inflammation and the hepatitis B virus can ultimately cause liver inflammation. The liver is an important organ in the human body and responsible for the removal of toxins and regulation of digestion (learn more about the function of the liver here). The hepatitis B virus can infect and disrupt critical functions of the liver in supporting your overall health. 

How the hepatitis B virus works 

In the case of the hepatitis B virus, the host is the liver cell. As the virus makes more copies of itself, the liver may become damaged, and sometimes it is unable to carry out its essential tasks to regulate metabolism, nutrients, and digestion. It is best to prevent hepatitis B infections when we can – and since antibodies are the best defense against the virus, the hepatitis B vaccine can be used to signals the body to make antibodies to fight the virus. The hepatitis B vaccine provides lifelong protection from the virus. However, this is only possible before infection with the virus. If somebody is already infected with the virus, antiviral therapy is used to control the virus and prevent liver damage – antiviral medications disrupt the life cycle of the virus by disabling viral receptors from binding to liver cells. 

Blood test panel to diagnose hepatitis B: 

The only way to tell someone’s hepatitis B status is through a panel of blood tests – the tests are all done at one time, and only one small tube of blood is needed. These tests are not included in routine testing, so it is important to ask your doctor to test you for hepatitis B or try to find a free screening event near you (http://www.hepbunited.org/). The panel consists of the following tests to determine your hepatitis B status: 

  1. HBsAg: 
    • This tests for the hepatitis B surface antigen in someone’s blood. The surface antigen is the protein that surrounds the virus and protects it from attack by the host. A positive surface antigen test indicates that the virus is present in the body. A “positive” or “reactive” result for HBsAg indicates that someone is infected with hepatitis B and can transmit the virus to others.  
  1. HBsAb 
    • This tests for the hepatitis B surface antibody in someone’s blood. The surface antibodies are produced by the immune system and can fight off the virus by attaching to the surface antigen protein. This test can detect the presence of these antibodies. Ideally this test will be ordered quantitatively (numerically). A “positive” surface antibody test (meaning numbers reading >10 IU/mL) means that a person has protection against the hepatitis B virus (either by vaccine or from a past exposure).  
  1. HBcAb (total) 
    • This is known as the hepatitis B core antibody test. The core antibody is produced by the immune system after infection with the virus. This test indicates an existing or past infection of the hepatitis B virus.

Important things to know about Hepatitis B Core Antibody (HBcAb) 

Someone who has markers of past infection, particularly hepatitis B core antibody, can be at risk for hepatitis B reactivation. Reactivation can be triggered by immunosuppressive therapies and cause significant life-threatening challenges. If you test HBcAb+, please talk to your doctor about what that means, and make sure you notify all future health care providers. 

How is reactivation with HBV defined? 

Reactivation is defined as the sudden increase or reappearance of HBV (hepatitis B virus) DNA. When the virus invades the cell, it forms a covalently closed circular DNA (cccDNA) in the nucleus of infected cells referred to as hepatocytes. Because cccDNA is resistant to antiviral treatments, it is never removed from the cells. Therefore, even after recovery from a past infection, the cccDNA is present and may reactivate. It is not clearly understood why this may happen, but certain factors may increase the risk for reactivation.

What puts one at risk for reactivation? 

  1. Virologic factors such as high baseline HBV DNA, hepatitis B envelope antigen positivity (HBeAg), and chronic hepatitis B infection that persists for more than 6 months.
    • Detectable HBV DNA levels and detectable levels of HBsAG can increase the risk for HBRr (reactivation) 
    • Testing positive for HBeAg also increases the risk for reactivation 
  2. Co-infection with other viruses such as hepatitis C or hepatitis Delta 
  3. Older age 
  4. Male sex 
  5. Cirrhosis 
  6. An underlying condition requiring immunosuppressive therapies (rheumatoid arthritis, lymphoma, or solid tumors) 
    • Certain medications can increase the likelihood of reactivation by more than 10%.  
    • B-cell depleting agents such as rituximab, ofatumumab, doxorubicin, epirubicin, moderate or high-dose corticosteroid therapy lasting more than 4 weeks. 

How to prevent reactivation of hepatitis B 

Hepatitis B reactivation is a serious condition that can lead to health complications, Reactivation is avoidable if at-risk individuals are identified through screening. Current guidelines recommend that individuals at the highest risk (those receiving B-cell depleting therapies and cytotoxic regimens) should receive antiviral therapies as prophylaxis before beginning immunosuppressive therapy. These antiviral therapies should also be continued well beyond stopping the immunosuppressive therapies. Be sure to talk to your doctor to be sure you are not at risk for reactivation.
