Today, all pregnant women are routinely screened for hepatitis B, but a growing number of doctors say this single test doesn’t go far enough to protect the health of women and children.

In a commentary published in the medical journal Pediatrics,  infectious disease specialist Dr. Ravi Jhaveri calls for a mandatory second test in pregnant women infected with hepatitis B. This test would measure the amount of hepatitis B virus (HBV) in her body (called viral load).

When women have high viral loads, their newborns can become infected even if they are immunized at birth and treated with HBIG (hepatitis B antibodies) to prevent infection. Continue reading "Expert Calls for Viral Load Testing in All Pregnant Women with Hepatitis B"

Father’s Day, June 21, is a day to celebrate the contributions men make in their children’s lives. It’s also a good day for fathers to acknowledge how valuable they are to their families and how important it is to take care of their health.

Living with chronic hepatitis B can be challenging. Here are some things dads can do to take care of themselves or family members infected with hepatitis B.

1. Get outside and soak in some sunlight and some vitamin D. People with hepatitis B who have vitamin D deficiencies have higher rates of liver damage, cirrhosis and cancer. A healthy diet provides vitamin D, but 80 percent of our vitamin D comes from 15 minutes of exposure to sunlight two to three times a week. So get outside and walk, garden, exercise and soak in some healthy sunlight.

This was an incredible opportunity to work together, network, and advocate on the Hill. Continue reading "Hepatitis on the Hill – HBV Personal Perspective and Action Alert"

The Fifty Shades of “Gray” of Hepatitis B Transmission – Part 1

1716136dfa105e7f9bdf96de16e31742All pun and a little fun is intended with this title, but the “adult” version of hepatitis B transmission is a serious concern. There are “shades of gray” when it comes to hepatitis B transmission and the degree of risk with sexual activity. Continue reading "The Fifty Shades of “Gray” of Hepatitis B Transmission – Part 1"

Research at the HBF’s Baruch S. Blumberg Institute

hbvvirus

Hepatitis C is now declared curable. Hepatitis B is still not, despite having been discovered nearly 50 years ago. An interview with Dr. Timothy Block of  the Hepatitis B Foundation and the Baruch S. Blumberg Institute. The future does look bright…

Perhaps this should not be a surprise, thinks Timothy Block, PhD, president and co-founder of the Hepatitis B Foundation (HBF) and its research arm, the Baruch S. Blumberg Institute. According to Block,there are two main reasons for the “cure deficit” between hepatitis B and C — funding and physiology.

He points out that commercial and federal investment in hepatitis C have been far greater than in hepatitis B. And that has clearly paid off in terms of finding a hepatitis C cure. “You get what you pay for,” he observes.

Physiologically, hepatitis B also presents unique challenges not found with hepatitis C — most notably cccDNA (or covalently closed circular DNA), the “mini- chromosome” produced by the hepatitis B virus. The cccDNA persists in the nucleus of the liver cell, where it can hide amidst the host’s own chromosomes, apparently out of reach of the cell’s own defense systems.

Acting like “an indestructible template,” cccDNA continues to produce virus particles throughout the life of the infected liver cell, even in people being treated with antiviral agents.

Hepatitis C, on the other hand, doesn’t enter the cell’s nucleus, so it’s possible to cure a person by stopping this virus from replicating long enough for the liver cells to regenerate.

But remember that people who have been “cured” of hepatitis C can still get re-infected,” Block cautions. The hepatitis C drugs apparently do not trigger an immune response that protects against re-infection.

In contrast, some people can be cured of hepatitis B, either naturally or through drug therapy. These individuals do seem to have long-term protective immunity. “And that’s what we are aiming for,” he declares.

Why We Need a Cure for Hepatitis B 

It can be argued that the approved antiviral agents are very successful in keeping the virus under control. So do we really need a cure? Definitely yes, Block replies emphatically.

Current antiviral drugs are effective, but need to be taken lifelong and are recommended for use in only about half of the infected population. And even after 10 years of use, the antivirals reduce HBV-related diseases by only about 50 to 60 percent. The drugs can also lead to the development of resistant hepatitis B strains (drug resistance).

For those who benefit from treatment, the antiviral drugs have been transformational and prove that medical intervention can be effective. However, there are millions who do not benefit and are still left vulnerable.

Clearly, new approaches to a “functional cure” are needed, which Block defines as “returning the risk of death due to hepatitis B to the level of someone who has a resolved infection.” And the person should not need to take any drugs to stay at this low-risk level.

Targeted Strategy for a Cure

The HBF/Blumberg Institute scientists, with their research partners from Drexel University College of Medicine, both located in the HBF’s Pennsylvania Biotechnology Center, are developing two types of therapies: direct-acting antivirals and innate host defense activators. The first type inhibits virus-host interactions and viral gene products; the second recruits the host’s immune system to attack and eliminate cccDNA and infected liver cells.

For each of these approaches, the researchers have identified key steps to target in the hepatitis B infection cycle, from virus entry into the liver cell, to cccDNA replication, to formation of virus particles.

For many of these steps, “Our scientists have developed assays that can be used to screen for new drugs. We are a recognized leader in designing and developing these assays and, for a time, had the only cccDNA- dependent cell lines,” notes Block. Almost 100 different cell lines for assays have been developed that can be used to screen for drugs that activate the innate host defense pathways.

For drug screening, cell lines are incubated with potential drug candidates to try and find new therapeutic drugs for future hepatitis B treatment. The strategic goal is to discover new drugs that complement existing therapies, but also enable the immune system to provide long-lasting antiviral protection, even when the person is no longer on drug therapy.

The strategic goal is to discover new drugs that complement existing therapies, but also enable the immune system to provide long-lasting antiviral protection, even when the person is no longer on drug therapy.

Several compounds in development already show some effectiveness in animal models. “We have a capsid inhibitor, a pregenomic RNA capsid inhibitor (JT Guo), an HBsAg inhibitor (A Cuconati), a cccDNA repressor (H Guo, A Cuconati, JT Guo), and an activator of innate host defense pathways (J Chang and JT Guo),” Block reports.

He is particularly excited about their stimulator of interferon genes (STING) agonist, which was very effective in mouse models. The research group is now working on a human STING agonist, although an appropriate assay for this compound still needs to be developed.

What the Future Holds 

“The Hepatitis B Foundation and its Blumberg Institute have contributed
to some of the most important work in studying the phases of the virus lifecycle that has led to the currently available drugs. Our researchers continue to be at the forefront in developing a promising pipeline for hepatitis B drug discovery,” says Block.

“I am absolutely confident that a cure is possible” he asserts. “After all, enough people with hepatitis B resolve their infections, either medically or spontaneously — even some people with chronic infections. So we know it’s possible.”

 

 

WHO’s New HBV Guidelines to Help Combat Africa’s Growing Hepatitis B Crisis

The World Health Organization (WHO) will release their first management guidelines for hepatitis B virus (HBV) by the end of 2014. For the first time, the guidelines will be geared towards resource-constrained countries, where the disease burden is high but resources are lacking. The new guidelines will be particularly welcome in African nations, where the incidence of viral hepatitis is increasing.

The overall scope of the World Health Organization’s new management guidelines for hepatitis B will include prevention, screening, and treatment of chronic hepatitis B and will be geared towards resource-constrained countries. Thus, WHO’s guidelines will be valuable for countries where the disease burden is high but resources are lacking.

The WHO Global Hepatitis Programme established a Guideline Development Group of external experts in 2013, which includes Hepatitis B Foundation (HBF) executive director Joan Block, and is co-chaired by Dr. Brian McMahon, who also serves on the HBF Scientific and Medical Advisory Board.

The new WHO guidelines will be particularly welcome news to African nations, where the incidence of viral hepatitis is increasing.

According to the WHO Global Hepatitis Survey 2013, the prevalence of chronic hepatitis B virus (HBV) infection on the African continent is up to 8% of the general population, and 75% of the population may have had prior exposure to the virus.

Yet, only two of the African member states that responded to the WHO Survey have a written national strategy to prevent and control viral hepatitis.

In Ghana, where the incidence of viral hepatitis is increasing, the sero-prevalence rate is high among blood donors (6.7%), pregnant women (6.5%) and school
aged children (15.6%), according to Mr. Theobald Owusu-Ansah, president of the Theobald Hepatitis B Foundation and the Hepatitis B Coalition in Ghana.

Compounding the lack of public health plans and national investment are factors common in many low-resource countries: limited awareness of hepatitis B among the public and providers, poor access to care, expensive therapies, and few liver specialists.

Global agencies are beginning to recognize the urgency of the situation. In addition to the WHO, the World Health Assembly is taking steps to combat the growing crisis. The Assembly adopted a second resolution on viral hepatitis in May 2014 that advises governments on how to prioritize and coordinate public health efforts.

But governments cannot tackle these problems alone, Mr. Owusu-Ansah believes. He urges governments to partner with commercial and nonprofit organizations to mobilize much-needed expertise and resources.

Hepatitis is Still the Silent Killer

Unknown

Great way to wrap up World Hepatitis Day events with a commentary from our viral hepatitis champions on Capitol Hill. A big thank you to Senator Mazie K. Hirono and Representatives, Michael M. Honda, Hank Johnson, and Bill Cassidy for their tireless efforts. Viral Hepatitis is a problem we cannot ignore!

Roll Call (online) By Sen. Mazie K. Hirono, and Reps. Michael M. Honda, Hank Johnson, and Bill Cassidy. July 31, 2014, 5 a.m.

Although the price of a revolutionary new hepatitis C treatment has made headlines recently, the real hepatitis crisis continues largely unreported. A more immediate problem for many Americans is not how much one hepatitis C treatment might cost; it is how many Americans are infected with viral hepatitis and do not even know it.

World Hepatitis Day, July 28, reminds us that more than 5 million Americans — or 2 percent of the population — are living with viral hepatitis. Yet the Centers for Disease Control and Prevention (CDC) estimates as many as 75 percent of these Americans are unaware they have the virus. This “silent killer” goes undetected because the virus often remains asymptomatic until it has already wreaked havoc on the liver, causing cirrhosis, end-stage liver disease, or liver cancer. According to the CDC, more than 30 percent of infected individuals will develop one of these conditions.

Meanwhile, since the majority of infected individuals don’t realize they have hepatitis, they do not take the necessary precautions and can unknowingly transmit the virus to others. More Americans die every year from hepatitis C than HIV.

Without effective intervention, it is estimated that deaths due to the hepatitis C virus will double, or even triple, in the next 20 years. Baby boomers — Americans born between 1945 and 1965 — make up 75 percent of Americans with hepatitis C, and are five times more likely to have the virus than the general population.

Hepatitis disproportionately affects communities of color. One in 12 Asian-Americans has chronic hepatitis B, and rates are increasing in African immigrant and Latino populations as well. Hepatitis C is twice as prevalent in African-Americans as in the general U.S. population. Despite the pervasiveness of viral hepatitis, and its potentially deleterious consequences for those infected, testing is not nearly as prevalent as it should be.

The Viral Hepatitis Testing Act, introduced both in the House of Representatives and the Senate, would create the first coordinated national system to address and combat viral hepatitis. It would expand hepatitis education, testing and care, with the priority of reaching those most at-risk. Most importantly, the legislation would help to halt the spread of viral hepatitis by strengthening health care coordination to ensure that patients who test positive are connected with the counseling they need to control their disease and prevent transmission. Through the Viral Hepatitis Testing Act, we can increase the number of individuals who are aware of their status from 25 percent to 75 percent in just two years.

Awareness is the antidote to this silent epidemic. Early diagnosis, determined through a simple blood test, can reduce the spread of viral hepatitis simply by making individuals aware of the infection and helping to connect them with education about the risks of transmission. Organizing our outreach and prevention to be culturally competent and available in different languages will help us reach those communities that are disproportionately affected. The CDC estimates that one-time testing of baby boomers alone would identify 800,000 undiagnosed hepatitis C cases nationwide, and prevent more than 120,000 deaths. We need action at the federal level to make viral hepatitis testing a national priority.

The true cost of viral hepatitis is not measured in the cost of one drug. It is how this epidemic will continue to grow if policymakers do nothing. We urge our fellow lawmakers to enact the Viral Hepatitis Testing Act and establish hepatitis awareness as a national priority.

We cannot ignore this problem.

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.
