October is Liver Cancer Awareness Month. It may be a sleeper of a event when compared to other health campaigns, but for us who live with viral hepatitis, it’s an uncomfortable but critical reminder of the importance of monitoring our liver health to prevent cancer.

Viral hepatitis, especially B and C, are viral infections that can cause liver cancer  (also called hepatocellular carcinoma or HCC.) Researchers are still studying why some people are more prone to liver cancer, but we who live with chronic hepatitis B or C have a 25 to 40 percent lifetime risk of developing liver cancer. The infection, which hijacks our liver cells to manufacture more virus, causes inflammation, scarring and even cancer as the liver cells grow out of control.

The longer we are infected with viral hepatitis, the higher our risk of developing liver cancer. While liver cancer often occurs in people with cirrhosis (severe liver scarring), some of us develop cancer without cirrhosis. Continue reading "Get Tested for Liver Cancer, Your Life May Depend on It"

Preparing for College, Dating and Disclosing Hepatitis B

When my daughter, who has chronic hepatitis B, packed for her freshman year of college, I peppered her with warnings about the need for standard precautions and condoms. I suggested wording for a future conversation where she would disclose her infection and negotiate safe sex with a potential partner.

I hoped these verbal dress rehearsals would empower and protect her, especially if that potential boyfriend turned her down. I wanted her to know that any rejection would not be about her or her hepatitis B, it would be about his fears. Continue reading "Preparing for College, Dating and Disclosing Hepatitis B"

This summer, students living with hepatitis B face a task that can be as stressful as SATs, entrance exams or writing college essays – completing their colleges’ health forms.

Some colleges and graduate schools require no medical information while others expect you to document in detail your allergies, immunizations, medical history and even undergo TB testing.

The good news is colleges want to make sure all students are vaccinated against hepatitis B, the bad news is the requirement can force students to disclose their hepatitis B infection. Here are some important things parents and students should know when filling out college health forms.

No school can deny you admission or treat you differently because you have hepatitis B. The Americans with Disabilities Act (ADA) prohibits discrimination based on disabilities, and that includes hepatitis B.

The Public Health Popularity Contest: Why You’ve Never Heard of Hepatitis B

charlotte_lee_hep_b-1Please welcome guest blogger Charlotte Lee, a pre-med Duke University Senior who has a passion for global health. Charlotte recently learned first hand how viral hepatitis  disproportionately impacts her community and how it tragically touched her own family.  

I walked into the first day of my internship ready to take on what I thought were the major public health crises of the world – malaria, AIDS, avian flu. Instead, my supervisor gave me a hefty stack of literature on hepatitis B. Sure, as a premed student I knew that hepatitis had something to do with the liver, but I was shocked to find out that hepatitis B was the most common serious liver infection in the world—one that chronically affects over 350 million people worldwide, including 1 in 12 Asian Americans—and I had never heard of it.

As a 21-year old Asian American who is passionate about global health, I felt cheated to only now discover that there is an infectious disease disproportionately affecting my community. Somebody should have told me about this! To then find out that it was completely vaccine-preventable – somebody should have told everyone about this!

About halfway through my internship, I found out that my grandfather died from viral hepatitis that he contracted through a blood transfusion. Suddenly the disease had a face, and it was a smiling man with wide rimmed glasses who used to sit me on his lap and feed me popcorn. It now feels like my duty to spread the word.

Hepatitis B is transmitted through blood or body fluids and causes deadly liver disease, including liver cancer, in 1 out of every 4 chronically infected people. Meanwhile, the famous West Nile Virus causes serious illness in less than 1% of infected people.

So, what makes this disease so easy to ignore? Hepatitis B is unfortunately an invisible disease; it can take up to 20-30 years before symptoms appear, at which time cirrhosis or liver cancer may have already developed. Hepatitis B is a silent killer and it affects a population invisible to the media and policy.  Anyone can get hepatitis B; however, people born in countries outside the US that have not instituted a strong hepatitis B testing and vaccine program have a large population (2 out of 3 people) who are unaware they are infected. Most get the disease at birth from their mothers who are chronically infected with hepatitis B. Many are impoverished and disenfranchised. Asian Americans make up more than half of hepatitis B cases in the US, but those from many other countries around the world are also at risk for having the disease.

However, the “it won’t happen to me, so I don’t care” rule doesn’t work for all diseases. Most people in the US don’t consider themselves at risk for AIDS, malaria, or tuberculosis, yet those diseases have plenty of name recognition.

One thing that AIDS, malaria, and tuberculosis all have in common is their deadliness. AIDS killed 1.47 million people in 2010. But did you know that viral hepatitis (hepatitis B & C combined) killed 1.44 million that same year?

Its symptomless nature also makes it hard to visualize. While other diseases invoke graphic images of illness, hepatitis devastates the liver. Most people probably don’t really know where their liver is located.

What frustrates me most is that it is a preventable disease, one that we can eradicate. The hepatitis B vaccine is one of the safest and most effective immunizations available, and it protects you for life. The CDC recommends all babies receive the vaccination at birth, yet many major hospitals in NYC are not immunizing newborns, with some vaccination rates as low as 20%.

Hepatitis B needs public health champions to get it into the spotlight. Policies need to be passed to fund much-needed education, surveillance, and treatment programs. Doctors should be educated about it, tests should be automatically ordered, and the government should pay for everyone to be vaccinated. This system doesn’t yet exist, but thankfully there are people working tirelessly towards it.

Monday was World Hepatitis Day 2014. This year, the Viral Hepatitis Testing Act was introduced in the House and Senate to provide $80 million over three years for prevention, testing, and linkage to care. This is the second term this bill has been introduced, and now it’s time to pass it. Locally, the New York City Council just introduced a $750K viral hepatitis initiative for 2015. And just last week, Councilwoman Margaret Chin was on NBC talking about the first ever NYC Hepatitis B Awareness Week. My internship will soon end, but advocacy never rests. There is always more to be done.

Liver cancer is the world’s second leading cause of cancer deaths, according to the latest World Cancer Report 2014 released by the International Agency for Research on Cancer (IARC), which is the specialized cancer agency of the World Health Organization (WHO). About 800,000 deaths per year are related to liver cancer. Continue reading "The World’s Second Deadliest Cancer Is …Preventable"

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

 

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.
