In 1914, the United States designated the second Sunday in May as “Mothers’ Day.” Its founder, Anna Jarvis, hoped the holiday would focus on her own mother’s work promoting peace and public health. Years later, Jarvis protested loudly when the holiday became better known for sentimentality and greeting card sales.
Our nation often loses sight of a holiday’s original intent, but this Mother’s Day we can bring back the goal of preserving public health, especially where it concerns mothers and infectious diseases.
Decades ago, researchers developed one of the most extraordinary life-saving vaccines–hepatitis B immunization. It saves lives in two ways: It protects children and adults from infection and it breaks the vicious cycle of mother-to-child infection. A baby born to a hepatitis B-infected almost always becomes infected. The vaccine, administered within hours of birth, breaks that cycle.
When the vaccine debuted in the late 1970s and early 1980s, most people with chronic hepatitis B had been infected at birth. When newborns and children are infected, their immune systems don’t recognize or attack the virus and the infection can continue indefinitely.
To stop this infection cycle, today all pregnant women are screened for hepatitis B. Babies born to infected women are immediately vaccinated and treated with HBIG (hepatitis B antibodies). This public health initiative has been extremely successful in dramatically reducing hepatitis B. However, the campaign’s focus has been primarily on newborns and the hepatitis B-infected mothers were often forgotten. Though hepatitis B infections had been identified, the infected mothers were often lost to follow-up, and this neglect continues today.

May is Hepatitis Awareness month. Why do we need an annual reminder about hepatitis B? Because 65 percent of the estimated 2.2 million people in the U.S. living with hepatitis B don’t know they’re infected.
Studies show when people know their hepatitis B status, they’re more likely to get monitored regularly, get treatment, and take steps to avoid passing on the disease to partners and their children.
So why are so many Americans unaware of their hepatitis B infection? Here are five roadblocks that stop us from getting tested for hepatitis B, and what how we can do to overcome them.
We feel fine, so we assume we’re not infected. Hepatitis B rarely causes symptoms. There are very few sensory nerves around the liver, so when a viral hepatitis infection strikes, we rarely feel its effects. As a result, most of us – especially if we were infected as children or newborns – never experience any symptoms for decades. So remember, “feeling OK” is no excuse to avoid testing.

“How did I get infected? Who could have infected me?” These questions are common when we are first diagnosed with hepatitis B.
Dumbfounded by the news, we struggle to understand when this infection could have occurred and who could have infected us with a virus that now threatens our health and well-being.
This diagnosis not only affects our health, it can weaken the trust we’ve placed in family members, friends and lovers. It threatens to dismantle basic beliefs we’ve held about fairness and honesty, and the assumption that if we treated people well that we would be treated fairly in return. Infections know no moral codes and ignore all the unspoken deals we have made with the universe. Continue reading "How Was I Infected with Hepatitis B? Making the Journey from Anger to Acceptance"→

The majority of people infected with hepatitis B lead healthy and normal lives. However, a small number of people may develop liver disease that will dramatically affect their quality of life and their ability to work on a short-term or long-term basis.
They may not be able to work for several weeks because of side effects from pegylated interferon treatment, or progressive liver damage could make it impossible to work and support themselves and their families even after treatment.
For decades, people living with chronic hepatitis B were told they would be “cured” only when they lost the hepatitis B surface antigen (HBsAg) and developed surface antibodies. It represented the holy grail of recovery that everyone hoped for, but very few achieved.
Today, experts are redefining what constitutes a “functional cure” from chronic hepatitis B and taking the surface antibody out of the equation.

To prevent liver damage and cirrhosis and reduce the risk of liver cancer–especially in older patients who’ve had hepatitis B for decades–doctors often prescribe long-term antiviral treatment. But some antivirals cause minor bone loss, which poses a problem for older patients with osteoporosis.
According to experts, the risk of bone loss from long-term antiviral treatment is low, and in fact some antivirals do not cause any bone loss at all. But if you are starting antivirals at an older age, or if you have been on antivirals long-term, experts recommend you monitor your potassium and vitamin D levels and regularly test for bone loss in the hip area so you know if you are experiencing bone loss and need a calcium or vitamin D supplement.

On Tuesday, March 8, more than 120 advocates from across the U.S. fanned out on Capitol Hill to talk to their representatives about the importance of funding the Viral Hepatitis Division of the U.S. Centers for Disease Control and Prevention (CDC). Dozens of people laid their hearts on the line and told their stories about how they, their families, and friends have been touched by hepatitis.
In meetings with Congressional staff, and in some cases their senators, they shared stories about family members who discovered they had hepatitis B only when they were diagnosed with late-stage, inoperable liver cancer. Others talked about how lucky they were to have been immunized at birth, considering their mothers were infected. Courageous advocates described losing loved ones to hepatitis B and C spread through the heroin epidemic, and recalled indifferent healthcare workers who saw only addicts instead of human beings who had lost their battle with both addiction and hepatitis.
Our goal was to get our representatives to allocate more funding for CDC’s hepatitis division, which is sorely needed. It’s CDC’s job to investigate disease outbreaks and educate the public and healthcare providers about infectious disease. For example, CDC publishes a variety of reports and promotional materials to educate people how to protect themselves against hepatitis B and C. The agency also funds a “hepatitis coordinator” in nearly every state whose job it is to help prevent hepatitis, investigate outbreaks, and collect data—a Herculean task for just one person.

If you have been diagnosed with chronic hepatitis B, your doctor has probably run several blood tests that show if the infection is harming your liver and identify what stage of infection you are in. Doctors consider all of these results when deciding if you need treatment and how often you should be monitored.
In this blog, we’ll examine how one of the tests — the HBV DNA or viral load test –can give you a snapshot into your hepatitis B infection and your health. The HBV DNA test is performed on a blood sample using a Polymerase Chain Reaction (PCR) technique that rapidly generates HBV DNA fragments so they can be measured. Today, viral load is usually measured using international units per milliliter (IU/mL). However, in the past it was measured in copies per milliliter (copies/mL), and in some regions and labs, it is still used.
If you ever need to convert copies into international units, there are about 5.6 copies in one international unit, so 5,000 copies/mL equals about 893 IU/mL. Remember to keep copies of your lab information on file so you can track your status. An Excel spreadsheet works great.
The sensitivity of HBV DNA tests may vary with each lab so it’s a good idea to use the same lab for your test. Labs usually measure down to less than 200 IU/mL. Below the threshold, the viral load is considered “undetectable” – something everyone with chronic hepatitis B wants to hear.
How HBV DNA results are presented mathematically on your lab report can be confusing. Because the amount of virus in the blood may be very high – in the millions or billions – the result may be displayed as an exponent or a log, rather than a whole number. You may need to convert these numbers to fully understand them.
What does viral load say about what stage of the virus you are in? Your viral load also varies over time depending on the “stage” of hepatitis B infection. That is why regular monitoring is so important.
Children and adults in the “immune tolerant” stage can have viral loads in the millions or even billions. It sounds scary, but it’s not unusual. Your viral load can remain very high for decades until your immune system begins attacking the virus. Most children and young adults who test positive for the hepatitis B “e” antigen (HBeAg) generally have high viral loads, though doctors typically don’t treat patients in this stage. Once their immune systems get rid of HBeAg and generate “e” antibodies (HBeAb), their viral loads begin to decline and liver enzymes (ALT/AST) normalize.
Adults with undetectable or low viral loads and no signs of liver damage are in an “inactive” stage. Adults with normal ALT (SGPT) levels, which usually indicate no current liver inflammation, and undetectable or viral loads less than 2,000 IU/mL generally do not require treatment. However, it is important to confirm with your doctor that there is no evidence of advanced liver disease. This phase may be lifelong, decades, or not long at all. That is why monitoring in this inactive phase remains important.
People in the “active” stage with elevated viral loads and signs of liver damage need treatment. These may be people that are HBeAg positive and unable to seroconvert and lose HBeAg and gain the antibody without experiencing significant liver damage. There may be a pattern of SGPT/ALT elevation that cycles up and down over time without mounting an adequate immune response to seroconvert. This can be dangerous, causing liver damage, which is why regular monitoring is key. You want to give your immune system the opportunity to try to mount an immune response and seroconvert but not at the expense of extensive liver damage. That’s why a knowledgeable doctor is so important!
Many people in their 40s, 50s or 60s, develop HBeAg-negative hepatitis B, though this may occur in younger individuals as well. Although individuals may have seroconverted and lost HBeAg (HBeAg negative/HBeAb positive), the virus is able to mutate allowing it to keep replicating, putting these patients at risk of liver damage. They may see the viral load start to creep up along with SGPT/ALT. Eventually they may require treatment with antivirals based on clinical guidelines doctors follow to manage their patients. Once again, monitoring is key!
Why is it important to measure HBV DNA during treatment? When daily antiviral pills (either tenofovir or entecavir) are prescribed, doctors measure your HBV DNA to see if the drug is working to reduce your viral load. Antivirals work by meddling with the viral DNA so the virus cannot reproduce effectively. Doctors measure your viral load to make sure the antiviral is working.
Why is measuring viral load important if you’re pregnant? Today, all pregnant women are screened for hepatitis B, and experts also want their viral loads to be measured. When pregnant women have high viral loads—exceeding 200,000 IU/mL—medical guidelines recommend antiviral therapy during their third trimester of pregnancy to reduce their risk of infecting their newborns. Babies born to HBV-infected women can become infected even if they are immunized at birth and treated with HBIG (hepatitis B antibodies) if their mothers have high viral loads.
It is important to remember that a viral load test provides you with important information, but it must be considered in relation to your other HBV and liver function tests results to determine if treatment is needed at all, or if you are responding favorably to current treatment. Although an undetectable or low viral load is good news, it does not necessarily guarantee that you have not, or will not experience liver damage. Hepatitis B is a tricky virus. Talk to your liver specialist about all of your test results.

Valentine’s Day may be a time to celebrate romance, but first you need a relationship. When you have chronic hepatitis B, starting a relationship and initiating sex is fraught with stress, hard disclosures, and the potential for break-up before an intimate relationship can even begin.
Recently, the Hepatitis B Foundation received this heart-breaking post from a 33 year-old man who thought his “inactive” hepatitis B could not be transmitted sexually.
“I’ve lived my entire life with this, but always thought it was just a normal thing (my mother said many Asians have it) and thought it was nothing to be concerned about as I never showed symptoms,” he wrote. “My doctor never said anything either. I lived my life thinking being a carrier was nothing out of the ordinary, and that I … could transfer it via blood, but could not sexually. Continue reading "Romance in the Air?

Medical guidelines suggest that individuals with HBeAg-negative hepatitis B with signs of liver damage face an “indefinite” or even lifetime commitment to taking daily antiviral pills.
In this week’s blog, we explore when—if ever—individuals with hard-to-treat HBeAg-negative hepatitis B can ever stop taking antivirals.
First of all, what is HBeAg-negative hepatitis B? Many people infected with hepatitis B at birth and who remain infected into their 40s, 50s or 60s, develop HBeAg-negative hepatitis B. Researchers believe that over time the virus mutates to evade the immune system. Though individuals may have lost the hepatitis B “e” antigen (HBeAg) and developed the “e” antibody, this mutated virus develops the ability to keep replicating despite the loss of HBeAg. And this mutated virus is capable of putting people at higher risk of liver damage.
Generally, doctors recommend treatment to HBeAg-negative patients when their viral load exceeds 2,000 IU/ML and their ALT liver enzyme levels, which rise when liver cells are damaged, are even moderately elevated. (Normal ALT levels are less than 30 for men and 19 for women.)
The most common antiviral treatments are either entecavir (Baraclude) or tenofovir (Viread). These two are considered the most powerful at quickly reducing viral load (HBV DNA) and have a very low risk of causing drug resistance, which is critical considering the long-term treatment required by HBeAg-negative patients.
But can individuals with HBeAg-negative hepatitis B ever stop treatment? Antivirals are expensive, without insurance tenofovir costs about $1,000 a month and generic entecavir costs about $407 in the U.S. Additionally, long-term antiviral treatment can cause bone loss.
Late last year, hepatitis B experts with the American Association for the Study of Liver Disease (AASLD) tackled this question and reviewed recent studies that followed HBeAg-negative hepatitis B patients who stopped antivirals. They found that even when these patients enjoyed two years of undetectable viral load and normal ALT levels during treatment, when they stopped only half of them were able to maintain a low viral low (below 2,000 IU/mL) and normal ALT levels.
The risk of dangerous “flares” after stopping treatment, “requires careful weighing of potential for harm and benefit,” the experts wrote. This is important because many HBeAg-negative patients are older and more vulnerable to liver damage and cancer.
In their new recommendations, AASLD experts make clear their findings are “conditional” and the quality of evidence found in the studies they reviewed is “low.” However, this is what they tentatively recommend:
Stopping treatment, “may be considered in persons who have (lost) the hepatitis B surface antigen (HBsAg). However, there is currently insufficient evidence to definitively guide treatment decisions for such persons.”
And, anyone who stops antiviral therapy should be monitored every three months for at least one year to see if their viral load rebounds or if they have signs of liver damage, including ALT flares.
Given the knowledge-gap about the long-term health consequences of HBeAg-negative hepatitis B, more research with longer durations of monitoring are needed, experts recommended. “Alternative treatment strategies for patients on long-term antiviral therapy, such as adding or switching to (pegylated interferon), warrant further study,” they concluded.
