First World Hepatitis Summit Focuses on Global Plan for Elimination by 2030

The joint North and South Americas group build relationships across borders to eradicate hepatitis B.
The North and South Americas group builds relationships to eradicate viral hepatitis.

The mood was euphoric. It was a love fest, actually. Last week, more than 600 policy makers, public health experts, and representatives from non-governmental organizations and patient advocacy groups from 80 countries were invited to participate in the first World Hepatitis Summit in Scotland hosted by the World Hepatitis Alliance in partnership with the World Health Organization (WHO). The Hepatitis B Foundation was pleased to be invited and to speak during the pre-summit meeting as well.

The message was serious. Hepatitis B and C kill more people each year than HIV/AIDS and tuberculosis, and combined are the seventh-leading cause of death worldwide, yet viral hepatitis as a global health concern remains mostly invisible and under-funded.

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"

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"

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"

The World’s Second Deadliest Cancer Is …Preventable

bandages

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"

Rallying Call

Welcome to the newly launched blog from Liver Cancer Connect, the Hepatitis B Foundation’s dedicated program on liver cancer. The blog will focus on issues that affect families facing liver cancer.

On the recent World Cancer Day 2014, we ushered in the new year with both sobering news and some optimism.

First the sobering news. The American Cancer Society recently reported1 that the number of new cases of liver cancer and the number of deaths due to this disease continue to increase.

The rate of liver/bile duct cancer has risen by 3% to 4% per year and mortality by about 2% over the past 2 decades. In sharp contrast, the death rate for all cancers combined has been steadily declining over the same period and the number of new cases has decreased for most cancers.

Liver cancer is the fifth most common cancer in the world, and the third leading cause of cancer-related deaths. In fact, every 30 seconds, one person in the world dies of liver cancer.

Yet liver cancer is largely preventable!

Eliminating the main risk factors for liver cancer — chronic hepatitis B and C infections and fatty liver disease — can stop the development of liver cancer.

Chronic hepatitis B and C infections, which cause about 85% of liver cancers worldwide, are preventable and treatable. A safe vaccine against hepatitis B (the world’s first anti-cancer vaccine) has been available since 1986. And while a cure is not yet available, hepatitis B infections can be kept under control with effective treatments. There is no vaccine yet for hepatitis C, but it can be cured. And fatty liver disease can be prevented by maintaining a healthy weight and diet.

Equally important in preventing liver cancer are screening and surveillance, which help to find the cancer early. Screening is the first test that a person undergoes to detect either an increased risk for liver cancer or the actual presence of the cancer. Surveillance refers to the regular monitoring for liver cancer on a ~6-month basis.

Early detection increases the number of treatment options available and the chances of successful treatment. A targeted oral therapy called Nexavar (sorafenib) is currently approved for liver cancer in more than 70 countries, and researchers are looking for new ways to fight liver cancer with fewer side effects. Many of these potential new treatments are being studied in clinical trials.

So there is room for optimism. With greater public awareness of the risk factors and how to prevent them, and new therapies being developed, it is possible to reverse the bleak statistics for liver cancer.

With the rallying call, “Liver cancer is preventable!” Liver Cancer Connect is putting the spotlight on the prevention of liver cancer.

Our patient-focused website (www.livercancerconnect.org) explains the main risk factors for liver cancer and the importance of screening, surveillance, and early intervention. Over the next few months we will be expanding the resources on the website and bringing you more news and information on liver cancer. We encourage you to explore the website and send us your comments.

Study Suggests Vaccine and HBIG Ineffective at Preventing “Occult” Hepatitis B in Babies Born to Infected Mothers

— Christine M. Kukka, Project Manager, HBV Advocate

A new study suggests for the first time that the combination of the hepatitis B vaccine and HBIG (hepatitis B immune globulin) may be ineffective in preventing “occult” hepatitis B in babies born to mothers infected with the hepatitis B virus (HBV). An occult infection occurs when a person tests negative for the hepatitis B surface antigen (HBsAg)—considered an essential antigen building block for HBV—while testing positive for HBV DNA. When this occult infection occurs, researchers suspect the HBsAg has somehow mutated so conventional lab tests can’t identify it.

 39.2% of U.S. Newborns Aren’t Getting Hepatitis B Vaccine at Birth

Which newborns aren’t getting immunized against hepatitis B in the U.S.? The infants who:

  • • Do not have health insurance
  • • Live in states without a universal hepatitis B vaccine supply policy
  • • And have only one provider who administered vaccines.

According to a U.S. Centers for Disease Control and Prevention study, published in the August issue of the journal Preventive Medicine, an alarming 39.2% of newborns missed the first, critical birth dose of hepatitis B vaccination that can protect newborns from hepatitis B even if their mothers are infected.

These results come from data analysis of the 2009 National Immunization Survey of 17,053 U.S. children, aged 19-35 months.

“Children who reside in states without a universal hepatitis B vaccine supply policy, and are not covered by health insurance are two important modifiable risk factors for not receiving the birth dose hepatitis B vaccination, future intervention studies could be needed to help control those modifiable risk factors,” CDC researchers wrote.

Researchers Suggest Banning or Restricting Lamivudine to Avoid Drug Resistance
A global team of researchers suggest lamivudine (Epivir-HBV) never be used to treat hepatitis B patients because it frequently leads to drug resistance and sets the stage for resistance to other antivirals, such as entecavir (Baraclude).

Lamivudine, the first antiviral approved for hepatitis B treatment, has fallen out of favor in North America and Europe because of its high rate of drug resistance. But because of its low cost, it continues to be commonly used to treat hepatitis B virus (HBV) infection in Asia and Africa, where the majority of the world’s hepatitis B patients live.

This report, published in the July 30 issue of PLoS One, examined the molecular make-up of the virus in many patients who had been treated with lamivudine as well as patients who had never been treated. They found the many untreated patients carry a mutation that allows HBV to quickly mutate and develop resistance to lamivudine.

“Our findings strongly suggest that the use of lamivudine will not benefit …patients,” they wrote because of the high risk of lamivudine resistance.

“Finally, since patients can quickly develop drug resistance to entecavir in the presence of lamivudine mutations, the lamivudine mutations can significantly compromise the efficacy of entecavir,” they concluded.

They proposed that doctor screen patients for these mutations before ever prescribing lamivudine,”… to most effectively treat chronic hepatitis B patients by selecting only sensitive drugs.” …
