Ghanians lined up for a viral hepatitis screening at last year's World Hepatitis Day event in Tamale, Ghana (Northern Region)

HBF is pleased to share World Hepatitis Day plans of our friend Theobald Owusu-Ansah of the Theobald Hepatitis B Foundation in Ghana. The Foundation is also a voting member of the World Hepatitis Alliance. 

On July 28th, 2013, The Theobald Hepatitis B Foundation and the Hepatitis Coalition of Ghana will join the World with one voice to celebrate World Hepatitis Day in Sunyani at Victoria Park. In attendance will be the Chiefs, members of Parliament, District Chief Executives, Municipal Chief Executives, Assembly Members and all the Opinion Leaders of the Region.

The Theobald Hepatitis B Foundation is a non-profit organization whose main aim is to educate and create awareness of hepatitis B and C to the general public, ranging from the causes, and symptoms of viral hepatitis, to preventive measures.

On World Hepatitis Day, the activities will start with an early morning Float with music and dance throughout the principal streets of Sunyani, along with the members and volunteers of the Foundation and the Coalition distributing educational materials to the crowds. These leaflets, posters, banners and stickers are part of the ongoing media blast that will draw the public’s attention to problem of chronic hepatitis B among the people of Ghana.

Free screening and hepatitis B vaccinations will be ongoing throughout the day’s activities. Resource persons will be delivering their messages and educating the general public about viral hepatitis. It is important that the people learn and understand whether or not they are positive or negative for viral hepatitis, and if they are positive, what is next.

The Delegation of the Government and other health care professionals will educate the public on Viral Hepatitis Policies and the way forward. Dieticians will also take the general public through the kind of food and diet one needs to eat, and the importance of avoiding alcohol, in order to defuse the public cry of the cost of prevention and treatment of hepatitis B.

Participating organizations will then take the opportunity to appeal for funds from the government officials and the Chiefs of the region present, in order to enable us to successfully organize our last programme of the year.

At the end of the event, the public will be provided with advice, and directed to seek medical information from qualified health professionals, in order to avoid falling into wrong hands of those trying to sell false cures for those with hepatitis B.

Please join us for our World Hepatitis Day activities in Victoria Park if you are in Sunyani, Ghana.

Celebrate Mother’s Day by Breaking the Cycle of Hepatitis B Transmission From Mother to Baby

1 Comment

Great blog written by Corinna Dan, RN, MPH, Viral Hepatitis Policy Advisor, Office of HIV/AIDS and Infectious Disease Policy, HHS , discussing the strategy to eliminate perinatal transmission of hepatitis B in the U.S. In many parts of the world, transmission from an HBV infected mother to her baby is the most common mode of transmission.  If you are a pregnant woman, please ask your doctor to screen you for hepatitis B. If you learn you have hepatitis B, talk to your doctor to be sure your baby receives appropriate prophylaxis within 12 hours of birth so you can break the cycle of transmission from mother to baby. Happy Mothers Day! 

Eliminating Perinatal Transmission of Hepatitis B: More Than Just a Test 

Hepatitis B in the U.S.

Nationally, new hepatitis B infections have been reduced by 82% since 1991 because of the availability of safe and effective vaccines, as well as improved prevention in healthcare settings. The Centers for Disease Control and Prevention (CDC) estimates that 1.4 million Americans are living with chronic hepatitis B infection. Unfortunately, many of these people became infected before the widespread availability of the hepatitis B vaccine in the early 1980s. Most are unaware of their infection, which places them at greater risk for severe complications of the disease, and for transmitting the virus to others. For women of childbearing age, this lack of awareness also increases the likelihood of transmitting hepatitis B to their infants.

Perinatal hepatitis B – spread from an infected mother to her infant at the time of birth – is estimated to account for 800-1,000 new infections each year in the United States. Unfortunately, this number of annual new, preventable infections has remained unchanged in recent years, which is why the elimination of mother-to-infant transmission of hepatitis B is one of the main goals of the Action Plan for the Prevention, Care & Treatment of Viral Hepatitis. As the Plan observes, the persistent annual number of perinatal hepatitis B cases is particularly concerning because approximately 90% of HBV-infected newborns develop chronic infection; up to 25% of these children will die of cirrhosis, liver failure, or liver cancer later in life.

Tackling Perinatal Hepatitis B

To achieve the goal of eliminating perinatal HBV, the Action Plan calls for the provision of postexposure prophylaxis (i.e., hepatitis B immune globulin and hepatitis B vaccine) to all infants born to HBV-infected women, a strategy consistent with the recommendations of the Advisory Committee on Immunization Practices (ACIP) in its “Comprehensive Immunization Strategy to Eliminate Transmission of Hepatitis B Virus Infection in the United States.” This recommended treatment is to be provided within 12 hours of birth followed by timely completion of the rest of the three-dose hepatitis B vaccine series, to prevent the infant from contracting hepatitis B. The Action Plan and ACIP also observe that care coordination is needed to ensure that infants born to HBV-infected women receive the services needed to protect them against hepatitis B.

A vital partner in these efforts to eliminate mother-to-infant transmission of hepatitis B is CDC’s Perinatal Hepatitis B Prevention Program (PHBPP) which supports activities in all 50 states, six cities, and five territories. The PHBPP was established in collaboration with state/local health departments and healthcare providers to promote use of the available tools – prenatal testing and vaccines – to reduce perinatal HBV transmission. The program works to identify pregnant women who are infected and provides case management services to ensure that infants receive the appropriate vaccines after birth to help prevent perinatal transmission. This program has been successful, ensuring that 95% of the identified infants born to infected mothers and case managed by the program received hepatitis B immune globulin and the first dose of hepatitis B vaccine within one day of birth and 83% of these infants complete the hepatitis B series by 12 months of age. In addition, whenever possible, the mother is counseled about hepatitis B and encouraged to talk with her healthcare provider for a full HBV evaluation. The program also seeks to identify household and sexual contacts of women who test HBV-positive – CDC reports that in 2011 the programs identified 9,681 such contacts – providing prevention information and recommending screening.

Despite these successful outcomes, challenges remain; the PHBPP estimates it identifies and case manages only about half of the expected births to hepatitis B infected women annually. Although hepatitis B screening is recommended for all pregnant women as part of routine prenatal care, not all women are screened. Some women do not seek or remain in prenatal care. In other cases, even when HBV screening occurs, health departments are not informed of screening results that reveal a pregnant woman is infected with hepatitis B – in some cases this is because such reporting is not required in that jurisdiction, in other cases it is an error or oversight. Under these circumstances, the health department cannot connect the expectant mother and her family to the services available through the PHBPP.

Another key support to efforts to eliminate perinatal HBV transmission is the implementation of provisions of the Affordable Care Act that will help improve prenatal hepatitis B screening. Under the Affordable Care Act, the hepatitis B test for pregnant women is among the Preventive Services that new health insurance plans issued after September 23, 2010 are required to cover without the consumer having to pay a copayment or co-insurance or meet her deductible. By making hepatitis screening more widely accessible and eliminating cost barriers, the healthcare law will also help bring us closer to the Action Plan’s goal of eliminating perinatal transmission of HBV.

In order to further reduce the number of infants who are perinatally infected with hepatitis B, healthcare providers, practices, and hospitals that care for pregnant women need to increase awareness and efforts to accurately report hepatitis B-infected pregnant women and refer the families to the PHBPP.

What Can Healthcare Providers Do?

Healthcare providers play a key role in eliminating perinatal hepatitis B. Steps that healthcare providers can take include:

  • Ensure that your practice is collaborating with the public health department to report women who are chronically infected so that their infants can benefit from case management. The CDC viral hepatitis reporting form [PDF 46KB] is available online.
  • Educate your patients about hepatitis B and listen to their concerns; the CDC has great educational materials available for patients.
  • Work with your local hospitals and birthing centers to ensure that they are following recommended policies and procedures.
  • Reach out to your state/local Perinatal Hepatitis B Coordinator if you have any questions or need additional assistance to implement the CDC recommendations.

What Can Pregnant Women Do?

  • Ask your healthcare provider if you were tested for hepatitis B and what the result of the test was.
  • Learn more about hepatitis B to make sure your new infant receives the preventive services needed to prevent hepatitis B infection at birth and throughout your child’s life.
  • If you learn that you are living with hepatitis B, check out the CDC’s frequently asked questions and talk with your healthcare provider to find out what you should do to stay healthy and ensure that you will be there to nurture and watch your child grow.

On this Mother’s Day during Hepatitis Awareness Month, please take the opportunity to learn more about hepatitis B and what steps you can take to realize the goal of eliminating mother-to-infant transmission of this preventable disease.

The Hepatitis B Foundation Participates in Liver Capitol Hill Day, 2013 – A Personal Reflection

Yesterday the Hepatitis B Foundation participated in the American Association for the Study of Liver Diseases (AASLD) annual “Liver Capitol Hill Day” visits. This is a great opportunity to get in front of state Senators and Congressmen in order to make requests known to them. It is also an opportunity to educate. As a constituent, your state representatives are interested in what you have to say. The “Asks” for the day were to support funding for liver related research, prevention strategies, and support of liver patient access to quality medical care.  Specifically, we were asking for NIH funding growth, rather than the 20% cut over the last decade, along with support of government agencies such as the CDC Division of Viral Hepatitis, and the delivery of health care systems and payment policies for patients living with liver diseases.  Prevention is also critical with specific asks for new, one-time hepatitis C testing and screening for hepatitis B for at-risk patients. As we are all aware, budgets are tight and we will all soon feel the effects of the Sequester. Research programs may no longer be funded, or severely cut, public health agencies and programs will be cut, and patients who are currently receiving medical assistance will suffer. For treated patients with HBV, it is essential nothing interrupts the daily antiviral use, and of course HBV and liver cancer prevention through screening, vaccination and surveillance is both necessary and cost effective in the long run.

Due to the Sequester, the day started in a panic for many Hill visitors. I was fortunate to arrive early – a good thing since I waited in a long security line for 45 minutes that wrapped around the building. As Maryland residents, Dave Li and I met with staff from both Senator Ben Cardin’s (D) and Senator Barbara Mikulski’s (D) offices.  Senator Mikulski was recently appointed the Chairperson of the U.S. Senate Appropriations Committee. This means she will have a great deal of influence on budget and spending decisions. We were told that due to the Sequester, the Continuing Resolution (CR) will remain in place for the remainder of the 2013, but Senator Mikulski is optimistic that the FY14 and future funding for the NIH, specifically, will be maintained. As a Maryland Senator, this is extremely important to Sen. Mikulski on many fronts. Senator Cardin has been making visits to agencies in MD, including the NIH, and researchers are frustrated they are unable to do their work.  Both Senator Cardin and Senator Mikulski support federal agencies (such as the CDC, Division of Viral Hepatitis, Public Health Agency etc.) and initiatives that provide care and services to meet the health care needs of Marylanders.  Fortunately this supports the Health and U.S. Health and Human Services (HHS) Viral Hepatitis Action Plan initiatives, since both Senators are supportive of prevention and surveillance initiatives.  Dave and I walked out of our Senate meeting feeling pretty good.

Unfortunately, the outlook was not so optimistic on the House side. We visited staffers from Congressman Chris Van Hollen and Congressman Elijah Cummings offices. Although they are working on budgets, they are meeting with opposition and resigned to deep cuts in their supported programs.  Congressman Cumming’s staffer was pleased to hear an optimistic viewpoint from Mikulski’s office.  Although clearly mixed signals from our House and Senate meetings, we can only hope that Congress will eventually work together and move forward with continued funding of agencies and programs that support those living with liver disease.

Please remember that your state Senators and Representatives have been voted to serve YOU. It is imperative that your voice be heard. If you don’t let them know what is important to you, important programs and agencies will be drastically cut.  You do not need to be a political machine to participate. Don’t know your Representative?   Find your Rep. on-line by putting in your zip code or state to learn who you need to contact. Find your Senator, Governor and Congressmen here. Call the Capitol switchboard’s toll free number at 1-888-876-6242 , or send an email  or letter with your asks, and your personal stories. Be sure your message is clear and concise, and personalize it if you can. You can visit your Representative or Senator when you are visiting Washington, D. C., or in the local, state office. Let your voice be heard – especially during this very difficult time.

High Viral Load, HBeAg Positivity Increased Risk for Mother-to-Infant HBV Transmission

6 Comments

The study published by Healio Hepatology, March 8, 2013 discusses the increased risk of mother-to-infant transmission in HBV positive moms who are HBeAg positive and have a high viral load. Current prophylaxis, where infants of HBsAg+ moms receive the first shot of the HBV vaccine and a shot of HBIG within 12 hours of birth, is successful greater than 90% of the time. However, according to the study, HBeAg+ pregnant moms with a viral load above 107  cp/mL(10,000,000 cp/mL) will transmit the virus to their infant despite prophylaxis. Since a particularly elevated viral load appears to determine the failure of current prophylaxis, the need for additional screening for these women and revised intervention strategies is necessary to prevent transmission to their babies at birth.

If you are a pregnant mom that is HBsAg+, please see a liver specialist for further evaluation to determine your HBeAg status and your HBV DNA viral load. If you are HBeAg + and have a high viral load, (a viral load near the 10,000,000 cp/ml threshold) you will want to talk to your liver specialist to determine if you and your baby would benefit from antiviral therapy in order to prevent transmission of HBV to your newborn. Although there are no official guidelines or recommendations, Registry data shows medications for hepatitis B appear safe during pregnancy. Talk to your doctor to see if this is a good option for you and your baby.

If you are a pregnant woman, please read and print HBF’s Chronic Hepatitis B in Pregnancy, and give it to the doctor who will be caring for you during your pregnancy. Sadly, IOM data shows HBV+ women in the U.S. are not always identified and educated about their HBV, and an opportunity for prophylaxis may be missed despite CDC recommendations that ALL infants receive the first dose of the HBV vaccine prior to hospital discharge.

If you live in a developing country, there may be no guidelines in place that automatically screen pregnant women for hepatitis B. Once again, read and print a copy of “Chronic Hepatitis B in Pregnancy” for your doctor. Insist you are screened for HBV, and if you are HBsAg+, please be sure prophylaxis will be available at the hospital where you will give birth to your baby. If you find you are HBeAg+, with a high viral load, please speak to a liver specialist to see if an antiviral is an option for you to prevent HBV transmission to your baby. Don’t’ forget to have your baby tested at 18 months to ensure your baby is HBV free.

*Please note you can convert copies per milliliter (cp/ml) to IU/mL for the article below using WHO’s international standard where 1 IU/mL = 5.2 copies/mL. Please ask your doctor or your lab if you have specific questions regarding the conversion.


Infants born to mothers with a high hepatitis B viral load, particularly those positive for hepatitis B e antigen, are at high risk for contracting hepatitis despite immunoprophylaxis, according to recent results.

Researchers evaluated 303 mother-infant pairs in which mothers tested positive for hepatitis B surface antigen (HBsAg). Maternal viral load and hepatitis B e antigen (HBeAg) status were determined, and children were tested for HBsAg at ages 4 to 8 months (n=250) and/or 1 to 3 years (n=53 for an initial test; n=183 for a follow-up test). All children received HBV vaccine within the first week of birth and at 1 and 6 months, with a 100% completion rate; children born to mothers who tested positive for HBeAg received hepatitis B immunoglobulin within 24 hours of birth.

HBeAg-positive mothers (81 cases) had higher viral loads than those who did not (7.4 ± 1.9 log10 copies/mL vs. 2.7 ± 1.4 log10 copies/mL; P<.0001 for difference). Chronic HBV infection was identified in 10 children, all born to HBeAg-positive mothers with high viral loads (range 6.5-9.5 log10 copies/mL), and all with the same HBV genotypes and subtypes as their mothers.

Investigators identified a significant association between maternal viral load and a child’s risk for infection via multivariate analysis, after adjusting for factors including age; birth type; infant gender, weight and gestational age, and feeding practices (adjusted OR=3.49; 95% CI, 1.63-.7.48 per log10 copy/mL increase). Predictive rates for maternally transmitted HBV infection were found to be statistically significant at 7 (6.6%; P=.033), 8 (14.6%; P=.001), and 9 (27.7%; P<.001) log10 copies/mL.

“High maternal viral load is the most important factor causing maternally transmitted HBV infection, and is significantly correlated with maternal HBeAg status,” the researchers wrote. “Our predictive model including multiple risk factors showed that children with a maternal viral load above 10,000,000 to 100,000,000 copies/mL (or would have a significant risk of infection despite immunoprophylaxis. Our data provide important information for the rational design of future screening and intervention strategies to further reduce maternally transmitted HBV infection.”

Personal Reflection on Yesterday’s FDA Vaccine Advisory Panel Review of Dynavax’s New HBV Vaccine

3 Comments

 

I was fortunate to have the opportunity to represent the Hepatitis B Foundation at yesterday’s FDA vaccine advisory panel review of Dynavax’s new HEPLISAV vaccine for hepatitis B.  I was there for the public comment period on the second day of the meeting with my prepared statement. I was surprised to find I was the only one there for public comment. Since I’ve never been to anything like this, I don’t know if that is typical or not.  I think my personal story with HBV, and the message from the HBF was important for the FDA panel to hear, so they were sure to be reminded that there are real people affected by chronic hepatitis B.

There has been a great deal of good press about the new Dynavax vaccine. In studies it has superior immunogenicity when compared to the currently available vaccines. Immunity is generated in 2 doses given one month apart, versus the currently available vaccines where it is a three shot series over 6 months. This is particularly important to subpopulations such as those undergoing dialysis, and diabetic adults who are encouraged to be vaccinated against hepatitis B – a new recommendation by the CDC this year. It is also important to the general adult population, where it is found that 30-50% of adults may not complete the 3 shot HBV vaccine series making them vulnerable to infection. This  need for HBV prevention via a more effective vaccine, particularly in needy subpopulations was what was stressed in HBF’s public statement.

I do believe the panel was well aware of the importance of HBV prevention and one doctor made mention of the importance based on “the public comment”, so they were listening. Another doctor mentioned the burden of the disease not only globally, but also in the US. That is often understated.

The FDA panel met both Wednesday and Thursday. The public comment period was Thursday, and I remained there for the vote on two vital questions.  The first question was about whether the immunogenicity data was adequate to support the effectiveness of HEPLISAV for the prevention of hepatitis B infection in adults 18 through 70 years of age? The vote cast showed unanimous agreement in the efficacy of the vaccine.

The other question was about whether the data was adequate to support the safety of HEPLISAV when administered to adults 18 through 70 years. Five members said “yes”, 1 abstained and 8 voted “no”.

Prior to both votes there was a great deal of discussion amongst the panelists, and the representative from Dynavax who responded directly to questions.

Ultimately it came down to a few key points.  It was clear that the panel was impressed with efficacy or level of immunity generated by this new, 2 shot series. This vaccine uses a unique adjuvant. An adjuvant is a substance that is added to the vaccine in order to increase the body’s immune response to the vaccine.  In this case it was a nucleic acid versus a lipid – details of which I do not even pretend to understand. Although this new adjuvant was exciting based on the great immunogenicity data presented by Dynavax, it was also a source of concern because the panel was not sure if there was enough study data that represented all demographics. In other words, this vaccine performed really well, but they weren’t sure if it had been proven safe in different ethnic groups such as African Americans, Asian-Americans, and Hispanics. Since the US is a melting pot, this is important.

The other concern was that the vaccine had not been administered along with other vaccines. Because this vaccine is to be given to adults, they felt it was important that it could be given when an adult came in for their annual flu shot, or another immunization. Adults just don’t get to the doctor’s office that often! Although this was clearly of interest, it was not a deal breaker like the lack of safety data among all demographics. There was the suggestion to introduce the vaccine into the current sub-populations that were in particular need, but not much discussion beyond.

The votes were cast and the panel and the audience dispersed. Looks like Dynavax will need to complete further studies before the vaccine is once again reviewed by the FDA panel for approval. Personally, I believe there’s a real  need and a place for this vaccine, but of course safety always comes first.

Why Give the Hepatitis B Vaccine to Infants?

1 Comment

The CDC recommends a birth dose of the hepatitis B vaccine for all babies. Pediatrician, Dr. Allison Shuman explains why in this informative video.

If you live in a part of the world where chronic HBV is at a medium (2-7% of population) or high prevalence rate (greater than 8% of population), your child is especially susceptible and at-risk for hepatitis B, with HBV transmission often occurring vertically from mother to child at birth, and horizontally from an HBV infected adult or another child’s infected body fluids to an unvaccinated baby or child. Please be sure that pregnant women are screened for hepatitis B. If mom tests positive for HBV, be sure baby receives a birth dose of the HBV vaccine and a shot of HBIG within 12 hours of birth. If mom tests negative for HBV, be sure that baby receives a birth dose of the HBV vaccine before leaving the hospital. Both babies of HBV infected and uninfected mom’s should receives shots 2 and 3 of the series according to schedule. Babies of infected mom’s should be tested at 18 months to be sure baby is hepatitis B free.

Please make arrangements with your doctor and the hospital to receive the HBV vaccine for your baby, prior to delivery, so you are sure the vaccine and/or HBIG are available at the hospital so prophylaxis can be given within 12 hours of birth. Please feel free to print and distribute  Chronic Hepatitis B in Pregnancy: Screening, Evaluation and Management (Part I and Part II) to your doctor.

 

Hepatitis B Diagnosis & Monitoring, Hepatitis B Prevention, Hepatitis Delta (HDV)

Hepatitis D Coinfection with Hepatitis B

Hepatitis D virus (HDV) – the “D” is for delta – is a viral enigma that doesn’t act like a normal virus. It is helpless – that is, it can’t infect a cell – without its viral accomplice, the hepatitis B virus (HBV), and makes infection with HBV worse.

Delta virus can only cause illness in those already infected with HBV, said Timothy Block, Ph.D., President and Co-Founder of the Hepatitis B Foundation, Professor and Director, Drexel University Institute for Biotechnology and Virology Research.

“It can take quiescent HBV and turn it into an acute, lethal viral infection,” Block said. “Liver disease – cirrhosis, liver failure – that might take decades to develop or could only take a year or two. Delta virus converts HBV infection into an emergency situation.”

“It’s one of the most severe forms of human viral hepatitis,” said Jeffrey Glenn, MD, Ph.D., Associate Professor of Medicine at Stanford Cancer Institute.

“Delta virus is a parasite of HBV because it encodes its own genome and coat-like protein but it doesn’t make its own envelope protein,” Glenn explained. “It steals that from HBV. It needs the B envelope protein to make its own, and this provides a means to infect new cells and subsequently make a fully formed viral particle to get out of those cells to infect others.”

Individuals can acquire delta virus two ways: Either after infection with HBV, which is called a “superinfection” and more likely to stay chronic, or a “co-infection”, which entails becoming infected with both viruses at the same time. In the latter, acute infections are more severe and increase the likelihood of developing liver disease much more quickly.

Worldwide, more than 15 million are infected, though fewer than 100,000 in the U.S. have the virus. It is concentrated in particular regions worldwide. Mediterranean areas such as southern Italy and southern Greece, for example, have larger than usual numbers of affected individuals, and in Turkey it is endemic. There are eight reported genotypes of HDV, which vary by geographical distribution and pathogenicity. Some believe that HDV’s incidence is declining. This is likely due to the hepatitis B vaccined and the resulting decrease in HBV carriers.

Because HDV is not a huge problem in the U.S., it flies under the radar screen of public awareness. Screening for HDV is not routinely ordered; however, infection with delta virus should always be considered when a patient with chronic liver disease suddenly gets worse.

Researchers have been frustrated in their attempts to develop effective treatments against HDV. Newer antiviral drugs that keep down levels of HBV DNA don’t do much against delta virus because they don’t affect the HBV envelope protein. The response rate to pegylated interferon alpha is typically poor.

With research there is always hope. Currently, there is a clinical trial of lonafarnib for the treatment of those coinfected with hepatitis B and D in the United States. It was originally developed for the treatment of different types of cancers. Perhaps additional information will come out of this year’s International Meeting on Molecular Biology of Hepatitis B Viruses. We shall soon hear.

Hepatitis D Fast facts:

—   Delta hepatitis is one of the most severe forms of viral hepatitis.

—   It is an incomplete viral particle that was discovered in 1977.

—   Approximately 15 million people are infected with HDV worldwide.

—   In the U.S., an estimated 6,000-13,000 people suffer acute HDV infection 
each year; 30,000 suffer from chronic HDV; and 1,000 Americans die 
from HDV-related diseases annually.

—   It is transmitted by blood from people already infected with hepatitis B.

—   Preventing hepatitis B, especially vaccination, will prevent HDV.

—   There is currently no effective treatment for HDV

An Event-Filled Hepatitis Awareness Month for the Hepatitis B Foundation and Hep B United Philadelphia

Hepatitis Awareness Month has come to a close, and it has been one exciting, busy month for those of us at HBF and Hep B United Philadelphia. In the course of 6 weeks, we have had many of our major events of the year – nearly all featured during Hepatitis Awareness Month or on Hepatitis Testing Day.  Have a look at what we’ve been up to this past month…

HBF preceded the month with its annual, signature fund-raising event. The Crystal Ball was held April 27th and was a very successful, enchanted evening for all in attendance. HBF exceeded goals for the year, and we were pleased to honor Dr. Howard Koh, Assistant Secretary of Health and Human Services (HHS), who was presented with the Baruch S. Blumberg Prize for his leadership in creating the HHS Action Plan for Viral Hepatitis.

The Hepatitis B Foundation was selected as this month’s featured partner by CDC NPIN. What a great honor, and a wonderful opportunity for HBF to showcase some of our programs, services and materials.

On May 15th, AAPCHO and HBF, with the support of the U.S. Department of Health and Human Services’ Office of Minority Health, launched the Hep B United national campaign.  This unique partnering and collaborative effort will bring attention and action to end hepatitis B – especially among high-risk Asian Americans and Pacific Islanders (AAPIs) in the U.S. You’re going to see a lot of activity out of Hep B United...

HBF’s Director of Public Policy & Affairs set off to Washington D.C. to attend the Congressional Briefing on Chronic Viral Hepatitis and Liver Cancer hosted by our champions in Congress.  Keeping Hepatitis in the hearts and minds of our elected Representatives is paramount in supporting viral hepatitis efforts in our country.

Hep B United Philadelphia wrapped up its awesome “B A Hero” PSA video contest and finalists and winners were announced. Check out these great PSAs!

Hepatitis Testing Day and the days leading up to the event were extremely busy for the Hepatitis B Foundation, Hep B United Philadelphia, and Partners. We kicked off testing day with our awareness-raising Flash Mob Event in Love Park in Philadelphia. This fantastic event included special guests Mayor Nutter, and Councilman David Oh, and plenty of other notable Hep B Heroes in attendance.  It was an honor to receive a City Proclamation by Councilman Oh, supporting efforts to eradicate hepatitis B in the city of Philadelphia. And of course the students put their spin on the event with a “B A Hero” Rap. You have to listen to this...

Saturday, Hepatitis Testing Day, Hep B United Heroes donned their hero capes for the Hepatitis Testing Day Event held at the Asian Pacific Heritage Festival in Philadelphia. It was a successful event with 112 screened. Those screened and in need of vaccination will be provided with the HBV vaccination series, free of charge, from the Philadelphia Department of Health.

That same day, Hepatitis B Foundation heroes hosted HBF’s B Informed Conference. This year’s conference was specifically directed to parents of children with hepatitis B. This was an incredible full-day conference. Expert specialists in the field addressed both the medical issues and personal challenges of parenting a child with hepatitis B.  It was a wonderful opportunities for parents to meet and discuss, face-to-face, with families facing like challenges. Lasting bonds were created that day. You’ll want to check back at a later time to read a reflection on the day, and access information presented by our expert speakers.

And finally we end this month’s awareness efforts this weekend by participating in the Philadelphia Independence Dragon Boat Regatta. Team Philadelphia Hep B Heroes will (hopefully) row their boat to victory, but even if they don’t win, they are winners at heart. The team is composed not of an expert crew, but rather Hep B United Philly community partners, student partners and staff. If you’re in Philly, stop by and cheer the team to victory. Plenty of team members will be at the event to raise HBV awareness and discuss hepatitis B testing, prevention and treatment.

There were a lot of Hep B Heroes out there this month.  Feel free to share the events of your organization this month!
