What’s the Difference?: Herbal Remedies and Supplements vs. Western Medicine

What’s the Difference?: Herbal Remedies and Supplements vs. Western Medicine

Around the world, people consider the use of herbal remedies or supplements as a natural treatment for hepatitis B and/or D infection. These natural remedies have historically been advertised to boost the immune system and improve liver health. Herbal remedies or supplements are described as products made from botanicals or plants used to treat diseases and maintain health. They can be produced in a variety of forms including liquid extracts, teas, tablets/capsules, bath salts, oils, and ointments4.

Why do people choose to use herbal remedies?

The use of these products over time has social-cultural influences related to the distrust of and unfamiliarity with western medicine for management of hepatitis B or D infection. While herbal remedies have been used widely across cultures and contexts, patterns of racism, medical mistreatment, and inadequate delivery of care in western medicine have influenced the present state of treatment practices. In response to these barriers to sensitive and effective health care delivery, many groups such as Hmong and African communities often rely on herbal remedies and supplements to treat medical conditions and ease suffering.

Silymarin, milk thistle, and Kampo medicine

The distrust of western medicine has contributed to more widespread use of supplements such as silymarin (milk thistle) and Kampo medicine, as alternatives to manage hepatitis B or D infection. Many people believe that Silymarin can improve liver health through its antioxidant and free radical-fighting properties. Traditional Kampo medicine has been used for over 2,000 years to treat a variety of diseases including hepatitis B. One herbal treatment that is frequently used is bupleurum which many people believe can protect the liver or heal liver damage. Despite possible liver health benefits, neither supplement is a treatment for hepatitis B or D and may sometimes cause further harm to the liver4. It is important to note that there is presently no cure for hepatitis B.

False claims and bad interactions

Additionally, several alternative medicine companies often make false claims and testimonials to convince people to purchase expensive alternative treatments with false promises that are not based on scientific evidence. Herbal remedies and supplements may also interact with certain medications prescribed for those with hepatitis B and D, so it is important to seek the advice of a health care professional before use of any of these products3,4.

Strides in western health care

The long-standing hesitancy to participate in western health care is well-reasoned and firmly rooted in past wrongdoing on the part of often fundamentally racist institutions. While the western health care system remains far from perfect, it is important to remember that many strides continue to be made to correct the misdeeds of the past, and conversations around health equity and the social determinants of health (including racism) are becoming more and more common. Meanwhile, research has found that beliefs and misconceptions around western medicine can delay care and increase morbidity rates of hepatitis B in high-risk communities2.

It is vital for those living with hepatitis B or D to stay informed with scientific knowledge about supplements and herbal treatments to ensure these products are effective and safe in their daily life. The coordination of hepatitis B and D care by providers must do better to support those impacted by the viruses, in a way that is culturally sensitive and not dismissive of the harm that has been inflicted on communities of color and immigrant communities, who are more likely to be affected by hepatitis B and D1.  Health care professionals and other service providers must continually work to improve their cultural humility. In addition, health care institutions practicing western medicine must work harder to ensure care is equitable and safe, and to center the voices, stories, and insights of community members in their work to repair the impacts of structural racism and medical mistreatment that have caused such deep distrust in western medical treatments.

HBV, Hepatitis B Awareness, United States

CHIPO Partner Highlight: United States Coalition for African Immigrant Health

The Coalition Against Hepatitis for People of African Origin (CHIPO) is a national community coalition that is co-founded and led by the Hepatitis B Foundation and is comprised of organizations and individuals who are interested in addressing the high rates of hepatitis B infection among African communities in the U.S. Over the past year, CHIPO has grown its membership to include over 50 community-based organizations and federal agencies, all of which are working to meet the common goals of raising awareness about hepatitis B among African immigrant communities, and increasing rates of screening, vaccination, and linkage to care. This month, we are excited to highlight the work of one of our newer national partners, the United States Coalition for African Immigrant Health, Inc., (USCAIH) and their Executive Director, Janet Afoakwah. Please enjoy a recent interview with Janet, as she describes her work, including successes and challenges, and the positive impacts she and USCAIH have had through their annual conferences and upcoming plans for expanding their portfolio and mission.

Could you please introduce yourself and your organization?

My name is Janet Afoakwah, and I am now the Executive Director of the United States Coalition for African Immigrant Health (USCAIH), previously known as the United States Conference on African Immigrant Health. USCAIH began as the National African Immigrant Project in 2005, supported by the U.S. Office of Minority Health, which provided a platform for national and regional conferences focused on African immigrant (AI) health. These conferences continue to be held on a yearly basis and attract a broad range of attendees, including federal agencies, academicians, researchers, policy makers, public health officials, students, community organizations, and a variety of other stakeholders. We are very excited because this year, in addition to hosting our annual conferences, we are going to be broadening the scope and focus of our work to include other services.

Could you tell me a little bit about what some of USCAIH’s programs are that specifically address hepatitis and other health concerns in African communities?

As we move forward into 2023 and beyond, USCAIH is going to be working toward achievement of some broader goals, including coalition-building; providing technical support to organizations working with AI communities; offering trainings and support in cultural sensitivity for direct-service organizations, especially those working in the areas of HIV and hepatitis, since this is such a crucial component of engaging with AI communities; organizing and expanding our website with important and relevant resources; collaborating and forming partnerships with like-minded organizations; inviting researchers to share their work with the community via a new podcast format; and providing a database where researchers working on AI health can consolidate their findings for direct use and application within communities. Data and research about African immigrants often are not disaggregated from that about African American and Black populations, so getting a clear picture of the health and health disparities impacting AI communities can often be difficult.

Is USCAIH focused in a specific geographic area or does it have more of a national reach?

Our conferences are both regional and national, and we also try to include researchers and organizations from many countries within Africa itself. The other services that we are hoping to expand will be focused on AI communities within the U.S., but all around the country.

Which countries are primarily represented in the African diaspora that USCAIH serves?

We work with folks from all countries and communities. We have been able to reach some communities a bit more effectively, due to existing relationships that our staff has with community members, but our hope is to eventually reach all AI communities within the U.S.

What are some of the biggest challenges in addressing hepatitis and other health concerns at the community level? How have you worked to overcome these? Are there any additional resources that would be helpful to have?

The biggest missed opportunities are in vaccination and screening for both hepatitis B and liver cancer. This gap is due to a variety of reasons, including general lack of health insurance and lack of funding for supportive programs, as well as inequities in healthcare access in general for many immigrant communities, which contribute to greater health disparities. Another large barrier is the lack of provider knowledge about the high risk of hepatitis B in AI communities.

The best ways to overcome some of these challenges are in the creation and sustainability of programs that are centered on AI communities and are culturally and linguistically competent – this is SO important. Another key element in breaking some of the barriers around cultural humility and especially provider awareness is in establishing partnerships and effective collaborations. Building awareness among trusted community and faith leaders, who in turn can pass this on to community members, is also critical. We have been able to launch and disseminate a podcast that covers health issues affecting AI communities, and we try to feature researchers and guests with lived experience of different health challenges, including hepatitis B, in order to raise awareness, dispel myths and misperceptions, and bring the severity of different health concerns into perspective. We are also working to consolidate resources on our website and to have all partners providing direct services around the country listed on there for easy navigation and connection.

Other more broad-sweeping, policy-level changes that need to happen include making hep B screening recommendations universal for all adults; and improving and centralizing linkage to care systems.

What do you think are some of the biggest barriers in raising awareness and addressing rates of hepatitis screening and linkage to care at the local, state, and federal levels? Do you think more could be done in these spheres to address this problem?

This is a big concern and one of the steps we have recently taken to address this is hosting a roundtable discussion intended to educate healthcare providers and professionals about hepatitis B and how to care for community members who might be living with HBV. Better provider education and linkage to care needs to be the order of the day. Community-based organizations should be supplementing the services that providers are offering. One big important change that can occur is for electronic medical records to include an automatic question about hepatitis B screening for all patients. All of this can be done with additional funding and support from the federal and state levels.

Do you see this issue as being connected to other concerns facing African immigrant communities?

Yes, there are a variety of health concerns that face AI communities in the U.S, many of which require similar approaches of cultural sensitivity and community and provider awareness to address. These include diabetes, heart disease, hypertension, and various forms of cancer.

What are your favorite parts about your job? What got you interested in this work?

I am passionate about hepatitis B and that is what actually got me into public health. I came into this work having previously led an HIV project at another organization. I love every aspect of my work! My favorite moments are in organizing conferences because they move so fast, have many moving parts, and are SO rewarding! These conferences are widely recognized as the premier gathering for discussing AI health – many organizations of all types are interested in presenting and sharing their work. The conference planning is tremendously collaborative and is an all-volunteer effort. Now, as Executive Director, I can see the whole picture of the conferences and the organization as a whole and am so excited to continue to be working on our old and new endeavors. Hosting the podcast has been a great experience as well, and a wonderful tool to interview a variety of people working in AI health, to raise awareness about important health topics like hepatitis B and to amplify the mission of USCAIH.

Any other thoughts or ideas you’d like to share for improving health and closing health disparities among African immigrant communities in the U.S.?

I just want to emphasize the importance of practicing cultural and linguistic competency, and of working in collaboration and establishing relationships with a variety of partners (including community- and faith-based organizations, health centers, and providers) and how important this is for community work. Establishing trust (which requires time and patience) and providing appropriate resources also cannot be overstated. Continuing to host conferences in order to have a space where ideas can be shared and collaborations can happen is key, and hopefully we can all work together to develop and execute a strategic plan of sorts for improving health and eliminating disparities in African immigrant communities in the U.S.

Thank you so much for taking the time to speak with me today and for sharing more about the great work USCAIH has done and will continue into the future!

 Thank you!

CHIPO Partner Highlight: Great Lakes Peace Centre

 The Coalition Against Hepatitis for People of African Origin (CHIPO) is a national community coalition that is co-founded and led by the Hepatitis B Foundation, comprised of organizations and individuals who are interested in addressing the high rates of hepatitis B infection among African communities in the US. Recently, CHIPO has started to expand its reach to communities in Africa and has welcomed new partners from the Continent. This month, in honor of Minority Health Month, we highlight a partnership between CHIPO and Great Lakes Peace Centre (GLPC) in Kasese, Uganda. CHIPO has recently provided GLPC with educational resources that are tailored for African communities, which GLPC is translating into local dialects and will use in a strategy to raise awareness and provide education about hepatitis B, primarily to rural women and youth in Kasese District. A recent interview with Bwambale Arafat, Head of Health and Policy Officer at GLPC, sheds light on some of the significant barriers that impede hepatitis B screening, prevention, and care in Uganda (and much of the African continent) and showcases some of the extraordinary work of GLPC on a host of issues, of which viral hepatitis is just one.

 CHIPO: Can you share a little bit about yourself? What is your connection to hepatitis?

Arafat: I work with the Great Lakes Peace Centre, which is a grassroots, youth-led organization, here in Kasese District, a rural area in Rwenzori region, western Uganda (near the border of the Democratic Republic of Congo, about 400 kilometers from the capital city of Kampala). Most of our work with hepatitis B is focused on raising awareness and providing education about the virus to women and youth in the area, who are the most important people to reach. We also engage in a lot of advocacy initiatives, as well as efforts to lower stigma and discrimination.

My personal connection to hepatitis B is the diagnosis of my uncle with hepatitis B and liver cancer and his death shortly thereafter. There was widespread misconception that he had been bewitched and poisoned by relatives. I have been working to try to dispel some of these myths and provide accurate information ever since. In 2021, I was honored as a World Hepatitis Alliance champion for hepatitis outreach work during COVID-19. I and GLPC are deeply committed to the cause of hepatitis B elimination by the year 2030.

CHIPO: Congratulations on the well-deserved honor! Can you share a bit about the work and goals of your organization?

Arafat: Due to its proximity to the Democratic Republic of Congo, Kasese feels the effects of war and conflict acutely, and the area is quite fragile. Peace and Conflict Resolution is the first of three priority areas for GLPC and is driven forward by the efforts and demographic dividends of young people. Health Promotion and Public Policy is the second priority area, which encompasses awareness and education about hepatitis, HIV/AIDS, malaria, and tuberculosis prevention, screening, and treatment, as well as nutrition assessments, counseling, and support, especially for mothers of children under five years of age. Water, Sanitation, and Hygiene is another topic of top concern, and initiatives in this sector included a hand-washing campaign for COVID-19. The last focus area under the Health Promotion umbrella is adolescent sexual and reproductive health, and especially promotion of education equity for menstruating young women and ending of stigma and discrimination around this, thus keeping young women in school for longer. Social empowerment happens through education, and people can donate to keep girls in school with financial support. The third organizational priority is to focus on climate change – GLPC distributes solar panels through public and private partnerships, as a great step toward sustainability and protecting the planet we share.

 CHIPO: What are some of the biggest barriers to hepatitis screening, prevention, and care in your community?

Arafat: As I mentioned above, the widespread presence of myths and misconceptions about hepatitis B, especially about transmission, is one of the biggest culprits in perpetuating the stigma and discrimination that still dominate the hepatitis B conversation and presents one of the biggest challenges to increasing screening and vaccination. Some ways that we are working to dispel some of these misconceptions are through our social media platforms, which all have huge followings by younger people. However, attitudes are very slow to change, and this is why the involvement of religious and community leaders in spreading accurate information and shifting the narrative around viral hepatitis is so important, and why personal testimonials and connections with people who are living with hepatitis B hold such power.

Other challenges to screening, prevention, management, and treatment of hepatitis B in Kasese include the enormous out-of-pocket costs of diagnosis and testing; the persistent lack of awareness among the general population – primarily lack of information, education, and communication; the lack of logistics and supplies for things like test kits and cold chain storage for vaccines; and the long distances and mountainous topography that make access to health facilities in larger cities difficult. Additionally, funding and resources from the government and other stakeholders remain inadequate, making it difficult to ensure that services will be available when they are needed. The Minister of Health and government of Uganda have created infrastructure to help with vaccination (they have provided 1 million USD for this reason), have recommended universal adult vaccination, and have also waived fees for viral load investigation. However, things like ultrasound scans, complete blood count panels, and other tests to determine when someone would need treatment for hepatitis are not subsidized. The government could also do a great deal more in terms of increasing awareness, investing money into management and care, prioritizing the birth dose of the vaccine to prevent mother-to-child transmission of hepatitis B, and addressing the stigma and discrimination so many living with hepatitis B routinely face.

Many infants also continue to be delivered by traditional birth attendants, who are not trained in preventing mother-to-child transmission of hepatitis B, and knowledge among community health workers in general is very low. There is also inadequate data and surveillance of the disease, and no records of screening, vaccination, or care are kept in the Health Management and Information System. There is a lack of clear guidelines around testing for the medical community and a lack of materials that can help to raise awareness and combat stigma.

We also really need to integrate hepatitis services into those that exist for HIV/AIDS. Machines that are used to test for HIV/AIDS can be recalibrated to also test for hepatitis. Electronic Health Records can be upgraded to include hepatitis B status. As awareness grows, patients can also hold health workers accountable for hepatitis testing, as they do now for HIV and syphilis. This conversation needs to start with the people themselves.

 CHIPO: How are you planning to use CHIPO’s materials and resources over the next year?

Arafat: We have a saying in Kasese: “When you talk in a foreign language, you talk to people’s heads. When you speak in their language, you speak to their hearts.” Our first priority is to translate CHIPO’s flip charts, takeaway cards, and guides for health educators into our local dialects of Lhukonzo and Runyakitara, in order to reach as many community members and stakeholders as possible. We will host four community educational events using the materials and in these events, will focus on hepatitis B overview, causes and prevention, common myths and misconceptions, and unmet needs in this area. These sessions will be moderated by NoHep Champions and Hepatitis Ambassadors, so that the community can hear from people with direct experiences of the disease and their voices can be amplified.

Additionally, we will host NoHep Champion Table Talks, which are informal discussions that will consist of young people living with HBV and pregnant women, who will share stories and build community. These talks will touch upon how people are doing physically, as well as with handling stigma, and will identify needed services, insights which can help to determine future programming and practices. These talks will also emphasize that no one is alone, and that hepatitis B is not a death sentence, but that people with HBV can live long and healthy lives. We will also convene community barazas (gatherings) with local leaders, including social workers, health workers, village health teams, hepatitis ambassadors, local council, and cultural, community, and religious leaders to conduct trainings on delivery of the educational materials. These will provide an opportunity to educate and invite open discussion. We will also hold continuing education courses on hepatitis B for healthcare professionals at health facilities, including community health workers, village health teams, and para-social workers. Finally, we are planning to compose a radio jingle related to hepatitis B that will be heard around the district.

Only 1 in 10 people in Kasese know their hepatitis B status. These materials can go a long way in changing that.

CHIPO: Thank you so much for your valuable insights and for all of the work you are doing! Do you have any final thoughts or messages that you would like to share?

Arafat: I would just like to mention our No Hep Mamas campaign, which we are also implementing for the prevention of mother-to-child transmission of hepatitis B. We are working to bring this campaign to more health facilities, and share this information in prenatal care settings, as stopping the cycle of transmission is truly the best way to eliminate hepatitis B.

CHIPO: Thank you so much again for your time today, Arafat, and we look forward to more inspiring work from you in the future!

Arafat: Thank you very much!

Clinical Trials, HBV, Hepatitis B Research, Hepatitis B Treatment

GlaxoSmithKline Recruiting for B-Together Hep B Clinical Trials

The company GlaxoSmithKline (GSK) is launching a new clinical trial, called B-Together, that will investigate how two study drugs might work together to treat chronic hepatitis B (CHB). Researchers are hoping to find new potential treatments that could be more effective than those that are currently available and could lead to positive results that last long after the treatment ends. Participants in this trial could play a role in shaping science and changing the landscape of CHB treatment around the world, and will have an opportunity to learn more about the disease itself.

The two drugs that will be investigated in this trial are GSK3228836 and pegylated interferon, also known as Pegasys. In a previous Phase 2 trial, people living with CHB received GSK3228836 for 4 weeks. The Phase 2b B-Together trial will test longer treatment with GSK3228836, followed by Pegasys, to see what effects this may have on viral antigens (such as HBsAg) in the body. 

About the Study Drugs

GSK3228836 is an investigational drug being tested as a potential treatment for CHB, meaning it is not yet approved for this purpose. Current medicines available to treat CHB only stop the virus from multiplying – they do not enable the body to fully clear the infection, so people have to keep taking these medicines. GSK3228836 is designed to stop the virus from producing proteins that may prevent the immune system from fighting the virus. Thus, the study drug may potentially allow the body to gain control over the infection.

The other drug used in this study, Pegasys, is a medicine that is already used on its own by doctors to treat CHB. Pegasys works by enhancing the body’s immune response to viral infections such as hepatitis B.

What Will Happen During This Trial?

During this trial, all participants will receive GSK3228836 followed by Pegasys. After you have finished treatment with GSK3228836, your doctor will check if it is appropriate for you to start treatment with Pegasys. If it is not appropriate, you may not receive Pegasys at all. At the beginning of the trial, you will be assigned by chance to one of two groups. Each group will receive the study drugs for different lengths of time. You will know which group you are in. The B-Together trial lasts about 79 weeks for each participant. This includes a screening period, a study treatment period, and a follow-up period.

Screening Period

At a screening visit, the study doctor will give you a physical examination, ask about your medical history, and conduct medical tests. The screening period may last up to about 6.5 weeks while the study doctor reviews the results of your screening visit to determine if you meet all requirements for participation.

Trial Treatment period

While receiving GSK3228836, you will visit the clinic for either 12 or 24 weeks. For the first two weeks of your treatment with GSK3228836, you will visit twice per week and for the remaining weeks you will visit the clinic once per week.

When you have finished treatment with GSK3228836, your doctor will assess if it is appropriate for you to start treatment with Pegasys. If it is appropriate, then you will then receive treatment  with Pegasys once a week for up to 24 weeks.

In some countries, it will be possible for you to self-inject Pegasys at home after discussion and training from your study doctor. This could reduce the number of times you have to visit the clinic.

Other study activities will vary from visit to visit and may include:

  •         Discussions about your health and medications you may take outside the trial
  •         Measurement of vital signs (i.e. blood pressure, pulse, weight)
  •         Collection of blood or urine samples
  •         Physical examination
  •         Questionnaires about your health and well-being

Follow-Up Period

During the 24-week follow-up period, you will not receive injections of study treatment, but you will complete other study visit activities as scheduled. There are eight visits scheduled in the follow up period. Your study participation will end about 72 weeks after your first dose of the trial drug.

Who Can Participate?

You may be eligible to participate in this trial if you are at least 18 years old, have been living with documented CHB for at least six months, and have also been receiving stable nucleos(t)ide treatment (not telbivudine) with no changes for at least six months prior to screening and no planned changes for the duration of the study. There are other eligibility requirements that the study doctor will review with you. Individuals who have a current co-infection with or past history of hepatitis C virus, HIV or hepatitis D virus are not eligible to participate in this trial. 

Where Is This Trial Taking Place?

This trial is ongoing in the UK, Spain, Russia, Poland, Italy, Korea, Japan, China, the US, Canada, and South Africa.

You can play a role in shaping your own health and the science of tomorrow! To learn more about this trial and check your eligibility to participate, visit https://clinicaltrials.gov/ct2/show/NCT04676724. 

Hepatitis B Awareness, World Hepatitis Day

292 Million People Worldwide Have Hepatitis B – So Why Do We Feel Alone?

 

Hepatitis B is the global pandemic no one talks about, yet 292 million people worldwide have been infected. In 2015, the World Health Organization estimated that hepatitis B caused 887,000 deaths annually.

Today, 292 million people have chronic hepatitis B1. Despite the availability of an effective vaccine, the number of people living with hepatitis B virus is projected to remain at the current, unacceptably high level for decades and cause 20 million deaths through 2030.

How can this happen? Viral hepatitis infection and death rates far outstrip that of ebola and zika. In fact, you have to combine the death toll from HIV and tuberculosis to find human suffering on par with what viral hepatitis causes around the world each year. How has this pandemic remained so hidden and ignored for so long? There are several factors that have kept hepatitis B off public health’s global radar. It’s a complicated, silent infection, often with few or no symptoms. Those who have it have been silenced by shame and ignorance, and more than two-thirds of those infected with hepatitis B have never been tested and are unaware of their positive status.

And then there’s avoidance by the global healthcare community. The development of a hepatitis B vaccine 40 years ago was thought to signal the death knell of this disease. While new infections have plummeted in North America and Europe, in impoverished countries, the vaccine is often not available or too expensive and infected mothers continue to unknowingly infect their children at birth.

There have been successful hepatitis B immunization campaigns around the world, even in poor, remote areas, but there’s a catch. The Global Vaccine Alliance (Gavi) provides a free hepatitis B pentavalent vaccine which is effective in children starting at 6 weeks of age. To break the mother-to-child infection cycle, a different and more costly hepatitis B vaccine must be administered as-soon-as-possible, within 12 hours of birth. However, this vaccine is often unavailable and out-of-reach financially in rural Africa and Asia, which is why chronic hepatitis B rates remain stubbornly high and are projected to remain unchanged.

To successfully combat hepatitis B, communities need to launch campaigns that combat stigma and teach how to prevent the spread of the disease through education and immunization. They need the resources to test people for hepatitis B and vaccinate those who need it. They also need to teach healthcare providers how to treat patients with liver damage.

Fortunately, we have started to see change. On May 28, 2016, at the United Nations World Health Assembly, 194 countries made a historic commitment to eliminate viral hepatitis by 2030. The Global Health Sector Strategy for Viral Hepatitis pledges to reduce deaths from hepatitis B and C by 65 percent and increase treatment by 80 percent. This action is the greatest global commitment to viral hepatitis ever taken.

On July 28, 2016, a campaign called NOhep, the first global movement to eliminate viral hepatitis, launched on World Hepatitis Day by the World Hepatitis Alliance. This day was chosen to mark the birthday of Baruch S. Blumberg, MD, D.Phil, who won the Nobel Prize in Medicine for the discovery of the hepatitis B virus.

Many of our partners and other organizations around the world are raising awareness to highlight World Hepatitis Day. Here are some of the activities you can support.

HDV, Hepatitis Delta (HDV), Liver Cancer

Does Hepatitis Delta Increase My Risk for Liver Cancer?

 

 

 

 

 

The short answer is, possibly.  Although there is extensive research to support the role of hepatitis delta in accelerating the risk for progression to cirrhosis (liver scarring) compared to hepatitis B infection (1,2) only, strong data directly linking an increase in risk for hepatocellular carcinoma (HCC) is lacking. It is known that coinfection promotes continually progressing inflammation within the liver by inducing a strong immune response within the body; where it essentially attacks itself (3), but the specific role of hepatitis delta in HCC isn’t fully understood. It gets complicated because although cirrhosis is usually present in hepatitis B patients who also have HCC, but scientists have not pinpointed a specific way that the virus may impact cancer development (4). There have been some small studies that have documented a correlation between hepatitis delta and an increase in HCC, but some analysis’s have even called the extent of its involvement in HCC as ‘controversial’ (5). However, other scientific studies may suggest the contrary.

Because hepatitis delta cannot survive without hepatitis B, and doesn’t integrate into the body the same way, it may not be directly responsible for cancer development, but it has been suggested that the interactions between the two viruses may play a role (6). It has also been suggested that hepatitis delta may play a role in genetic changes, DNA damage, immune response and the activation of certain proteins within the body – similarly to hepatitis B and may amplify the overall cancer risk (7,8). One of these theories even suggests that hepatitis delta inactivates a gene responsible for tumor suppression, meaning it may actually promotes tumor development, a process that has been well-documented in HCC cases (9,10).

Regardless of the specific impact or increase in risk for HCC due to the hepatitis delta virus, hepatitis B is known to increase someone’s risk, with 50-60% of all HCC globally attributable to hepatitis B (11). People with hepatitis delta coinfection still need to be closely monitored by a liver specialist, as 70% of people with both viruses will develop cirrhosis within 5-10 years (12). Monitoring may be blood testing and a liver ultrasound to screen for HCC every 6 months. Closer monitoring may be required if cirrhosis is already present, or to monitor response to treatment (interferon).

Living with Hepatitis B

Hep B and COVID-19: Resources for Individuals and Healthcare Workers

Amidst the global challenges we are facing, the Hepatitis B Foundation remains a resource for our community and our partners. COVID-19 is a rapidly developing situation, and information about it’s impact on those living with liver diseases such as hepatitis B is still emerging. During this time, it is important to be prepared for all situations, including limited access to necessities. Below, we have provided several tips and tools to help you protect yourself and stay healthy. 

Preparing for Quarantine or Self-Isolation

To prevent transmission of the virus, countries around the world are instating protocols requiring individuals to stay home and to practice social distancing as much as possible. If you are currently on hepatitis B medication, it is important to make sure that you have enough medication for an extended period of time. Call your doctor and ask them to write a 90-day prescription for your treatment if they have not done so. The American Association on the Study of Liver Diseases (AASLD) reports that many insurance companies are waiving refill limits on prescriptions, so you can request additional medication at any time. As skipping a day of treatment may cause the virus to flare and increase the risk of liver damage, it is essential to speak with your healthcare provider about long-term medication access.

If you had a doctor’s appointment scheduled during this time period, see if your doctor’s office is scheduling telehealth appointments or holding virtual meetings with their clients instead. Some services for those living with hepatitis B, such as ultrasounds or even blood work, may be delayed until further notice unless there is a cause for concern. You may want to consider scheduling a virtual meeting to discuss your situation and address any questions you may have about recent test results or concerning symptoms. Most telehealth services should be accessible directly from your phone if you do not have access to a computer. 

It is also important to continue protecting the health of your liver.  Consider stocking up on canned vegetables and fruits instead of items that may be unhealthy.  Be sure to read the nutrition labels, as some canned goods can have high sodium and sugar contents. If you have the means, you can also purchase fresh fruits and vegetables, and freeze them to use over the upcoming weeks. Physical activity – both indoor and outdoor – is encouraged during this time as well! Practice social distancing for outdoor activities, and get creative for indoor workouts. 

Protecting Yourself During the Pandemic:

Many individuals are wondering how those living with hepatitis B can protect themselves from COVID-19. Current recommendations are to practice social distancing and to wash your hands frequently with soap and water. Be sure to scrub your hands for at least 20 seconds! If soap and water are not available, a hand sanitizer that contains 60% or more alcohol will also kill the virus. 

Dr. Robert Gish, Medical Director for the Hepatitis B Foundation, says, “If you’re living with chronic hepatitis B or C without cirrhosis, you should be following the standard precautions for the coronavirus infection. The coronavirus does affect liver inflammation and liver enzymes and can also cause liver dysfunction, so individuals living with cirrhosis will be at higher risk for liver disease progression and decompensation.” Dr. Gish also recommends that individuals living with cirrhosis take special precautions, such as increased monitoring of liver enzymes. If you develop COVID-19, Dr. Gish recommends close monitoring of both liver enzymes and liver function. The Centers for Disease Control and Prevention (CDC) also recommends that those with serious chronic conditions self-isolate with or without an official stay-at-home order.

Hepatitis B Research

Hepatitis B Research Review

 

 

 

 

Welcome to the Hepatitis B Research Review! This monthly blog shares recent scientific findings with members of Baruch S. Blumberg Institute (BSBI) labs and the hepatitis B (HBV) community. Technical articles concerning HBV, Hepatocellular Carcinoma, and STING protein will be highlighted as well as scientific breakthroughs in cancer, immunology, and virology. For each article, a brief synopsis reporting key points is provided as the BSBI does not enjoy the luxury of a library subscription. The hope is to disseminate relevant articles across our labs and the hep B community. 

Interferon-inducible MX2 is a host restriction factor of hepatitis B virus replication – Journal of Hepatology

  • This paper from Fudan University in Shanghai, China reports the interferon-induced GTPase MX2 as a host protein which inhibits HBV replication. Interferon alpha (IFN-α) is a type 1 interferon used in a subset of HBV-infected patients to help eradicate the virus. IFN-α treatment results in the activation of hundreds of genes known as interferon-stimulated genes (ISGs). Which ISGs are most important in eliminating HBV infection remain largely unknown. GTPases are a large family of hydrolase enzymes which convert guanosine triphosphate (GTP) to guanosine diphosphate (GDP). GTPases act as molecular switches in an array of cellular process including signal transduction, cell division and differentiation, and protein translocation. The myxovirus resistance (Mx) proteins are highly conserved, dynamin-like, large GTPases. Humans have two MX proteins: MX1 and MX2, both of which are known ISGs. While MX1 is known to have broad-spectrum antiviral activity against RNA viruses, MX2 has only recently been shown to inhibit human immunodeficiency virus 1 (HIV-1), hepatitis C virus (HCV), and hepesviruses. MX2 antiviral activity against HIV-1 and herpesviruses is mediated through MX2 binding to the capsid of invading viruses whereby it likely inhibits the uncoating of viral DNA. In HCV, MX2 was found to interact with non-structural protein 5A (NS5A) thereby inhibiting its localization to the endoplasmic reticulum (ER). MX1 has been reported to inhibit HBV replication by inhibiting nuclear export of viral RNas and/or trapping the HBV core protein indirectly. This study investigates the anti-HBV activity of MX2. First, the group compared the anti-HBV activity of MX2 to four other innate immune restriction factors: HNRNPU, SAMHD1, MOV10 and A3G. They co-transfected these genes along with the HBV genome into HUH-7 cells and then assessed HBV replication via Southern blot. MX2 was found to inhibit HBV replication the most, with 44% of viral DNA compared to the empty vector control. The group then used siRNA, Southern blot, Western blot, fractionation, and mutagenesis studies to elucidate the anti-HBV role of MX2. Overall, they found that MX2 significantly reduces HBV RNA levels and indirectly impairs cccDNA formation. MX2 was found to contribute substantially to the anti-HBV affect of  IFN-α. Both the GTPase activity and oligomerization status of MX2 were found to be important in conferring its anti-HBV affect. In the future, MX2 and its related pathways may be exploited to help prevent the formation of and even eliminate cccDNA in those infected with HBV.

An HBV-encoded miRNA activates innate immunity to restrict HBV replication – Journal of Molecular Cell Biology

    • This paper from the Tianjin Medical University in China explains how an HBV-encoded microRNA (miRNA) activates the innate immune system in humans infected with the virus. miRNAs are short (21-25 nucleotides) sequences of mRNA which are mainly involved in post-transcriptional silencing of genes. miRNAs are produced in plants, animals, bacteria, and viruses. Typically, miRNA acts to silence protein translation from a messenger RNA (mRNA) by binding to the 3′ untranslated region (UTR) of the mRNA. This binding may result in the destabilization or cleavage of the mRNA or inhibit the function of the ribosome during translation. This group has identified an miRNA from the HBV genome called HBV-miR-3 which they have previously reported inhibits HBV replication by targeting the HBV mRNA transcript. In this paper, the group first shows that HBV-miR-3 is produced in an amount proportional to virus infection in vitro. They also show that HBV-miR-3 is secreted from cells in exosomes. Next, using both patient serum samples and in vitro assays, the group found a positive correlation between HBV-miR-3 production and IFN-α signaling pathways. In patient serum, levels of HBV-miR-3 positively correlated with levels of the hepatitis-related parameters alanine aminotransferase (ALT), aspartate transaminase (AST) and type I IFNs (IFN-α and IFN-β). In cell culture, they observed an increased expression of  the IFN-α-induced antiviral effectors OAS-1, MX1, IFIT2 and IFIT3 in the context of HBV-miR-3 production. Further experiments indicated that HBV-miR-3 promotes IFN-α production by suppressing the expression of suppressor of cytokine signaling 5 (SOCS5), allowing for signal transducer and activator of transcription 1 (STAT1) to be activated by phosphorylation. Finally, the group shows that HBV-miR-3 released from infected cells in exosomes  promotes polarization of the M1 macrophage phenotype. M1 or “classically activated” macrophages secrete high levels of pro-inflammatory cytokines and thereby fight pathogenic infections. Taken together, these results show that aside from directly limiting HBV replication, HBV-miR-3 also indirectly limits HBV infection by activating the host innate immune system. The virus may do this in order to adopt host miRNA-mediated antiviral machinery and thereby alleviate pathogenesis so that persistent and latent infection can continue. In the future, levels of HBV-miR-3 may be used as a diagnostic marker for HBV infection and may shed light on novel antiviral approaches.

Innate and adaptive immunity associated with resolution of acute woodchuck hepatitis virus infection in adult woodchucks – PLOS Pathogens

    • This paper from Georgetown University in Washington, DC is a “woodchuck paper”. That is, it is an in vivo study of woodchucks infected with Woodchuck Hepatitis Virus (WHV). WHV infection is used as a model system for HBV infection in humans because WHV is similar to HBV. This type of study is beneficial, especially when studying the immune response to hepadnaviruses, because humans infected with HBV are typically asymptomatic in the early stage of infection and because it is not advisable to obtain liver biopsies from these patients. The woodchuck infection model offers a controlled infection with WHV at a known time-point, which can be monitored by regular blood tests and liver biopsies. When studying the immune response to hepadnaviruses, liver biopsies are necessary because the liver is the site of the infection. About 95% of adults infected with HBV “clear” the virus; that is, their immune system is able to fight off the virus completely, giving them life-long immunity. The other 5% become chronic carriers of HBV and are at a high risk for liver cirrhosis and hepatocellular carcinoma (HCC). However, 95% of infants infected with HBV become chronic carriers. Differences in the immune systems of adults vs infants have been attributed to this drastic difference in chronicity, but what specific components of the immune system are important in staving off chronic infection remain unknown. Overall, the data presented here indicate that there is an early, non-cytolytic control of WHV replication mediated by interferon gamma (IFN-γ) produced mainly by natural killer (NK) cells. This was followed by an adaptive immune response characterized by antibody production, a T-cell response, and cytolytic action of cytotoxic T lymphocytes (CTLs). This adaptive immune response led to both the decline of WHV as well as symptoms of acute hepatitis B (AHB) including sinusoidal and portal inflammation in the liver.

Differential alternative splicing regulation among hepatocellular carcinoma with different risk factors – BMC Medical Genomics

    • This paper from the University of Utah School of Medicine in Salt Lake City, Utah uses bioinformatics to examine how different risk factors for hepatocellular carcinoma (HCC) correlate with differential alternative splicing (AS) of tumor mRNAs. After a primary (precursor) mRNA transcript is produced in the nucleus by RNA polymerase, the transcript must “mature” by having regions called “exons” removed in a process called splicing. Splicing results in an mRNA transcript consisting entirely of “introns”. The mRNA is then capped at its 5′ end with a 7-methylguanosine residue and polyadenylated at its 3′ end with about 200 adenylate residues (poly-A tail). This mature mRNA is able to exit the nucleus and be translated into protein by a ribosome. Alternative splicing (AS) describes how one genomic region may code for many different protein variants (isoforms) by differential spicing of the primary mRNA transcript. A common mechanism of AS is “exon skipping”, where exons are included in some mature transcripts but not others. HCC has various risk factors including alchohol consumption and infection with hepatitis B or C viruses (HBV and HCV). This study used data from The Cancer Genome Atlas (TCGA) and  the Genomic Data Commons (GDC) Data portal to analyze 218 patients with primary HCC associated with HBV (n = 95), HCV (n =47), or alcohol (n = 76). They used RNA sequencing (RNA-Seq) data to examine differences in AS between three groups: HBV vs. HCV, HBV vs. alcohol, and HCV vs. alcohol. 143 genes were identified with differential AS across these groups and these genes were found to be mainly involved in immune system, mRNA splicing-major pathway, and nonsense-mediated decay pathways.Of the 143 AS genes identified, eight and one gene were alternatively spliced specific to HBV and HCV respectively. The human leukocyte antigen genes HLA-A and HLA-C had differential AS in HBV-related HCC compared to both HCV- and alchohol-related HCC. HLA ptoteins are part of the major histocompatibility complex (MHC) class 1 surface proteins which present foreign antigens to the immune system. Also, exon 3 of  the gene encoding inositol hexakisphosphate kinase 2 (IP6K2) was skipped more often in HBV-related HCC than in other groups. IP6K2 is known to be involved in cancer metastasis. This study represents the first investigation into how different risk factors of HCC may affect the AS status of specific genes.

The Cytosolic DNA-Sensing cGAS–STING Pathway in Cancer (Review) – Cancer Discovery

    • This review from the Memorial Sloan Kettering Cancer Center in New York City covers current understanding of the cGAS-STING pathway in the context of cancer. While it is well known that the cGAS-STING pathway is an evolutionarily-conserved  antiviral signaling platform, how this pathway is involved in tumorigenesis remains unclear. In preneoplastic (early tumor) cells, cGAMP produced in response to DNA damage is exported out of the cell to activate STING in neighboring antigen-presenting cells (APC). This activation results in the release of type 1 interferon (IFN) from the APC, which cross-primes natural-killer and CD8 T-cells to kill the preneoplastic cells. In this context, the cGAS-STING pathway plays a role in tumor surveillance by activating innate immunity to create “hot spots” of inflammation. However, there is also evidence that activation of the cGAS-STING pathway can contribute to tumorigenesis.  In advanced, metastatic tumor cells, chronic activation of STING by chromosomal abnormalities leads to suppressed production of IFN and the upregulation of Nf-kB-driven pro-survival genes. This can drive chronic inflammation of the tumor as well as its metastasis to other locations in the body. Activation of the STING pathway in tumor cells may also allow for their immune evasion by inducing autophagy and upregulating expression of programmed death-ligand 1 (PD-L1). Another interesting finding mentioned in this review is a STING-independent form of cGAS activation which may drive tumorigenesis during cell division. During mitosis, cytoplasmic cGAS may bind to repeat sequences in the centromere regions of chromosomal DNA. Once bound, cGAS may interrupt the repair of sister chromatids by homologous recombination, causing aneuploidy in daughter cells, a hallmark of tumor cells. Of additional interest, mentioned in this review are several recent findings regarding the cGAS-STING pathway, including: cGAS can be activated by extracellular DNA entering the cell in exosomes; cGAS can be activated by “micronuclei” which are small nuclear compartments in the cytoplasm formed by chromosomal instability; cGAS-DNA complexes turn into a liquid phase to produce cGAMP; STING dimers oligomerize to form tetramers when activated; palmitoylation of STING has been proposed to recruit TANK binding kinase 1 (TBK1) and interferon regulatory factor 3 (IRF3).

Lay Summary: 
This month, the innate immune system was the focus of HBV research. Scientists hope to find how the innate immune system interacts with HBV during viral infection and proliferation. Doing so will shed light on host factors which lead to chronic infection and inform antiviral strategies. Notably, this month a human protein, MX2 was found to have potent anti-HBV activity by preventing cccDNA formation. Also, a microRNA encoded by HBV called HBV-miR-3 was found to activate the human innate immune system to limit HBV replication. This month, a paper studying woodchuck hepatitis virus (WHV) traked activation of the innate immune system as well as he adaptive immune system in an acute infection model. Also this month, concerning hepatocellular carcenoma (HCC), the alternative splicing of mRNA in tumors was found to vary in HCC patients based upon their risk factor (HBV, HCV, or alcohol). Finally, a review was published this month concerning STING, an innate immune protein which is not activated by HBV infection but which may prove a valuable tool for cancer treatment.
