Hepatitis B Prevention

Hepatitis B Vaccine Schedule: Standard, Accelerated, and Combination

Getting poked with a needle is never fun, but it’s an extremely important part of protecting yourself and others from infectious diseases! The hepatitis B vaccine is known to be one of the most effective vaccines in the world – and very safe too! As a blood-borne disease that typically has no symptoms, hepatitis B can easily be spread by accident – simply because people are unaware that they have it! Modes of transmission include mother-to-child during birth, unprotected sex, injection drug use, unsafe medical procedures, and the sharing of personal items that may contain blood remnants, such as body jewelry, razors, and toothbrushes. Although certain precautions can be taken to prevent transmission, the only way to completely protect yourself is to get vaccinated. Once you have been vaccinated, you are protected for life!

There are a few options for receiving the hepatitis B vaccination. In most countries, the vaccine is available through a doctors office or a health clinic. The most common option is the standard three-dose vaccine. This consists of three separate doses of the vaccine given through intramuscular injections. In order for the vaccine to be effective, there must be a minimum amount of time between doses. If the minimum amount of time is not followed, the vaccine will not provide full, long term protection from the infection.

3 Dose Schedule:

  • 1st Shot – At any given time, but newborns should receive this dose in the delivery room within 24 hours of birth
  • 2nd Shot – At least one month (or 28 days) after the 1st shot
  • 3rd Shot – At least 4 months (16 weeks) after the 1st shot (or at least 2 months after the 2nd shot). Infants should be a minimum of 24 weeks old at the time of the 3rd shot.

In the United States, there is an FDA approved 2-dose vaccine called Heplisav-B. However, Heplisav-B is only approved for adults. Both doses must be from the Heplisav-B vaccine only.

2-Dose Schedule (U.S. Only):

  • 1st shot – At any given time
  • 2nd shot – At least 28 days after the first shot.

Accelerated Vaccine Schedule

At the moment, Heplisav-B is the only vaccine that is approved on a shortened schedule. Some doctors may offer an accelerated vaccine schedule for special circumstances. However, the accelerated schedule is generally not recommended for individuals who do not need the vaccine within a certain time period. The Centers for Disease Control and Prevention only recommends the accelerated vaccine schedule to those who are traveling on short notice and have a high risk of facing exposure, or to emergency responders in disaster areas. Multiple studies have shown that the minimum time between doses is necessary in order to receive full protection against the infection. If doses are given too close together, the body does not have enough time to create an immune response to the vaccine’ leaving you vulnerable to transmission. If you must complete an accelerated schedule, four doses of the vaccine are required in order to achieve full, long-term immunity.

4 Dose Schedule:

    • 1st Shot – At any given time
    • 2nd Shot – 7 days after the first shot
    • 3rd Shot – Between 21 and 30 days after the 1st shot

 

  • 4th Shot –  1 year after the first shot

 

 

Combined Vaccines

In some cases, the hepatitis B vaccine is administered along with other vaccines or as part of a combination vaccine. Examples of combination vaccines that offer protection against HBV include: 1) The pentavalent vaccine which is used for children and protects against a total of five infectious diseases and 2) the combination hepatitis A and B vaccine. While the pentavalent vaccine is offered as the first dose for children in many countries, it is not ideal unless the child is able to get the birth dose of the HBV vaccine. It can only be given once the child is six weeks old, leaving the infant unprotected during the gap. Therefore, it is strongly recommended that children receive a monovalent hepatitis B dose of the vaccine at birth. For women that are HBsAg positive, the birth dose is the best chance to prevent hepatitis B transmission to the next generation and must be given within 24 hours of birth.

Pentavalent Vaccine Schedule         

  • 1st Shot –      Monovalent at birth                                                                         
  • 2nd Shot-      Pentavalent at 2 months of age                     
  • 3rd Shot –      Pentavalent at 4 months of age
  • 4th Shot –      Pentavalent at 6 months of age                         

The combined hepatitis A & B vaccine – which is only for adults – can follow the 3 dose vaccine schedule or, if necessary, the 4 dose accelerated schedule. More information on combination vaccines can be found here.

Before you get vaccinated, it is important to get tested for hepatitis B! The vaccine will not work for those who are currently infected or have previously been infected. Those who have recovered from a past infection will produce antibodies to the virus and will not have to worry about becoming reinfected or infecting others – but the virus can become reactivated if they undergo immune suppression, so it is important for you and your doctors to know if you have recovered from a past hepatitis B infection. However, those who are currently infected will still be able to transmit the virus – even if they receive the vaccine. Therefore, it is important to know your current status. Ask your doctor or local healthcare provider for the 3-panel hepatitis B blood test (HBsAg,HBsAb,HBcAB) to find out your status today!

 

Hepatitis Delta (HDV), Uncategorized

Phase 3 Clinical Trials Opening for Hepatitis Delta Patients

Phase 3 clinical trials have been announced for two drugs, Lonafarnib and Myrcludex (Bulevirtide) for the treatment of hepatitis B and delta coinfection.

Phase 3 studies compare new possible treatments to the current standard treatment, to see if it is more effective and/or safer than the current standard of care. Phase 3 studies are randomized control trials, which means that patients will be assigned to one of several different treatment groups. These studies usually evaluate the new treatment over a long period of time but special designations by the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA), such as Fast Track, Orphan Drug, Breakthrough Therapy Designations and PRIME eligibility status will speed up this process and bring these drugs to approval more quickly. Because the only currently approved treatment for hepatitis delta is pegylated interferon, which is often less than 30% effective, there is an unmet need for faster development of more treatment options.

Phase 3 clinical trials for Lonafarnib are currently recruiting hepatitis B and delta coinfected patients in the United States. Ninety-two international trial site locations have also been announced and will take place in Belgium, Bulgaria, Canada, France, Germany, Greece, Israel, Italy, Republic of Moldova, New Zealand, Pakistan, Romania, Span, Switzerland, Taiwan, Turkey, United Kingdom and Vietnam. This clinical trial, run by Eiger Biopharmaceuticals, will test the new drug Lonafarnib in combination with other treatments. For more information about the study, visit www.D-LIVRstudy.com or clinicaltrials.gov.

Bulevirtide, made by MYR-GmbH Pharmaceuticals, has also announced that its phase 3 clinical trials will be opening in 2019. Trial site locations have not been announced yet. For more information about this study, visit clinicaltrials.gov.Click here for more information on locating additional clinical trials. If you are considering joining a clinical trial, discussing it with your liver specialist can be helpful in determining if joining a trial may be right for you.

It is very important for hepatitis B and delta patients to be managed by a doctor, preferably a liver specialist, who is familiar with managing hepatitis B and delta coinfection.

Liver Health

Hemochromatosis: Treatment, the Liver, and Hepatitis B

Genetic conditions can be an unfortunate part of life, but with information and support, some can be managed. By sharing your family health history and learning about genetic disorders that run in the family, measures can be taken to prevent damage and help your loved ones stay healthy!

Hereditary hemochromatosis is one of the most common genetic disorders. The Centers for Disease Control and Prevention (CDC) reports that approximately 80-90% of hemochromatosis cases are from the hereditary form of the condition1. Due to a mutation in the HFE gene, the body begins to produce too much iron – a process

Northern European Countries

called iron overload. Iron overload can cause complications in the liver, heart, and pancreas2. According to the National Organization for Rare Disorders (NORD), hereditary hemochromatosis has several names that all refer to the same disorder: bronze diabetes, classic hemochromatosis, hemochromatosis type I, hemosiderosis, HFE-related hemochromatosis, HH, and primary hemochromatosis. The two non-hereditary forms of hemochromatosis are secondary hemochromatosis and neonatal hemochromatosis. Both are considered to be rare. Although the hereditary form is common, the exact number of patients worldwide is unknown. Globally, it is estimated that 1 in 227 individuals of Northern European descent is living with hemochromatosis. In the U.S, an estimated 1 million individuals are impacted as well 2. 

Not everyone who has the mutant gene develops hemochromatosis. These individuals are known as “carriers”; they can pass the gene on without suffering from the symptoms. Symptoms include joint pain, fatigue, abdominal pain, unexplained weight loss, and a bronze or grey skin color. For most patients, symptoms do not appear until middle age (40-60) because it takes time for the iron to build up in the body. Males tend to be affected more often than women and experience symptoms at a younger age as well 3,2. Some carriers for the mutant gene may develop a more severe version of the disorder called juvenile hemochromatosis. With juvenile hemochromatosis, patients experience an excessive amount of iron overload that can lead to liver and heart damage between the ages of 15 and 30.

Hemochromatosis, the Liver, and Hepatitis B

While the body needs a certain amount of iron to function, iron overload can be dangerous.  Hemochromatosis can lead to two major liver issues: hepatomegaly and cirrhosis. Hepatomegaly is the enlargement of the liver and cirrhosis is the scarring of the liver. Both issues can impair the liver’s ability to function and filter out toxins that enter the body. They can also increase a person’s risk of developing liver cancer. Recently, two major studies by the University of Exeter and the U.K. University of Connecticut, and the U.S. National Institute on Aging have found that a person living with hemochromatosis has four times the risk of developing a liver disease than a person who is living with the disorder.

For individuals living with hepatitis B, it is extremely important to understand any behaviors or conditions that may have a negative impact on your liver. Since one liver disease can increase your risk of another liver disease, it is important to identify the disorder as early as possible, especially if you have any of the following risk factors:

Risk Factors for Hereditary Hemochromatosis:

  • Men or postmenopausal women
  • Of Northern European descent
  • Having a relative with hemochromatosis

Risk Factors for Secondary Hemochromatosis:

  • Alcoholism
  • Family history of diabetes, heart disease, or liver disease
  • Taking iron or vitamin C supplements

Hepatitis B patients do not have an increased risk of developing hemochromatosis4. However, if you have any of the above risk factors, it is important to get tested. Hemochromatosis can easily be identified by a comprehensive look at a person’s family health history, a physical exam, and a simple blood sample. Your doctor will then use the blood sample to run a series of tests that may include transferrin saturation (TS), serum ferritin, or liver function tests. In certain cases, the doctor may also perform genetic testing to see if the mutant HFE gene is present.

Treatment

Treatment for hemochromatosis is available! Based up tests results, family history, medical history, and the appearance of symptoms, the doctor may suggest a few different treatment methods. In therapeutic phlebotomy – the most common treatment method – a patient undergoes regular blood draw to lower the amount of iron in the body. This method is effective, affordable, and typically lasts for an extended period of time. Through iron chelation therapy, patients can either receive an injection or orally consume a medication that will lower the amount of iron in your blood. Finally, some doctors may suggest changes to your diet, such as eating less vitamin C, avoiding alcohol and shellfish, and not taking iron supplements. Dietary changes are mainly used to prevent liver damage.

Patient Perspective: Living with Chronic Hepatitis B & Fighting it On All Fronts

 

This post is by guest blogger Mariam. Mariam works at a charity cancer hospital and is interested in philosophy. She is currently learning french and enjoys spending time by herself and the mountains. 

When you are first told that you have a chronic disease that is treatable but has no cure, you are suddenly confronted with an enemy on multiple fronts—you have to fight it within your body, inside your mind, your heart and in the outside world. Chronic hepatitis B: nearly 15 million people are living with it in Pakistan. In the world, 292 million people are silently suffering from this , and most are unaware (which is 9 out of 10 people globally). It is a tragedy that 2 out of 3 liver-related deaths are caused by this infection which is preventable and treatable. There are many reasons why this disease is prevalent in a developing country like Pakistan that lacks a proper healthcare system; where there are no pregnancy screenings or an effective mechanism to ensure babies are vaccinated against this. It’s an infection that can be transferred through blood (most commonly from an infected mother to her baby during delivery)  and sexual intercourse and  so it is not difficult to understand how this disease travels from one generation to another, silently. Elimination of viral hepatitis by 2030 is one of the millennium goals of the World Health Organization, but we cannot achieve this without dedicated efforts by all the stakeholders that include health-care professionals, patients, media, and policy-makers. I am primarily interested in sharing the patient’s perspective, in hopes that it will encourage others to fight this epidemic.

A Patient’s Point of View

The fact it’s a chronic illness means you are in for the long haul and you have to be prepared to take care of yourself by regular monitoring/medications (depending on what stage you are at) for the rest of your life. One can argue that’s bad but it’s not a big deal as we have people who suffer from high blood pressure, bad eyesight, or diabetes and they also have to regularly take care of themselves. The problem is that hepatitis B is an infectious disease, a fact that contributes towards stigma surrounding its diagnosis. Suffering from flu makes me feel like a hazard to others. Having an infection that I cannot get rid-off certainly makes me feel bad and, in a way, dirty. I have to be cautious and aware that my blood is hazardous for others and I have to be constantly aware of all the possibilities I can be harmful and ways to prevent it. It’s a progressive disease which can be treated at a certain point, so when you go to follow-up appointments, you feel like a ticking bomb is inside you and you need to be able to identify the period when the bomb goes off so you can treat the damage. Because current hepatitis B medications are most effective when there are signs of liver damage, the treatment is often only given during this phase. The inherent uncertainty makes you hate hepatitis B.

Fighting Discrimination and Stigma

Living in a conservative society, if you are one of the few fortunate ones aware of your diagnosis, how do you deal with it? I kept it to myself because I did not want people to define me through my illness. I did not tell my parents or friends because I did not want them to see me as ill or worse, to pity me. I needed time to process it without having to deal with other’s opinions and judgments. Three years ago, I was diagnosed with hepatitis B during regular pre-employment screening. I did not even know anything about this disease. I had a biopsy to determine the stage of the disease. Then I went to a few follow-ups. Unfortunately, after a while, I stopped because I did not want to think about this illness. I wanted to forget about it so I tucked it away, in the farthest corner of my mind. I did not know many people with whom I felt safe talking about this. Until one day, I was at a fundraising event for a charity cancer hospital where I got the chance to sit with a doctor. He was a stranger and a doctor, so in a way I felt safe telling him why I’m so interested in trying to understand where my country stands in the fight against hepatitis B—I told him I was diagnosed with it. At one point he asked me if I’m on treatment,  and I honestly told him I am supposed to be on follow-up. He said, “What do you mean, supposed to be?” That slight hint of disappointment made me feel I failed in taking care of myself. It’s easier to sound irrational inside your head but when you share it out loud, it does not feel nice. He told me that first, I need to sort out myself before trying to make a difference in the world of hepatitis B. I am grateful for the brief discussion with him which gave me the courage to think about re-scheduling my long overdue follow-up appointment. It gave me the clarity that I wanted to share my story with others in hopes that those who are fighting hepatitis know they are not alone. Sharing my story also helps me feel that I am not alone either.

I feel it is very important to fight the stigma surrounding hepatitis. Only then we will be able to talk about it and bust the myths. Only then we will be able to discuss ways to fight it on the ground. It is common in a conservative society to put a label on you as defective and exclude you from everything. For instance, marriage is still, by large, the union in this culture after which people have sexual intercourse and have kids; both occasions that can be possible causes of transmission of this virus. If, before marriage, a person is aware of their diagnosis, they can ensure that their partner is vaccinated and safe. However, in this society, there is also a prevalent culture of arranged marriage which makes this whole discussion almost impossible because so-called “perfection” is demanded. I wonder if submitting your hepatitis status with a marriage certificate was compulsory, would it help in data collection and early detection of this disease or would it encourage stereotyping. What if it was possible to vaccinate every child who starts school to be vaccinated against hepatitis B? After all, mandatory vaccinations are common in other countries. But what about children who can’t afford to go to a school? Can we link hepatitis B vaccination confirmation mandatory with every birth certification? This works in many other countries that vaccinate every baby born – we need to able to fight hepatitis B with a strong response such as this.

I also have an obsession with trying to understand this virus that is sharing my body. So my brain imagined a story to help understand how the chronic hepatitis B works. There are the good guys (liver cells) and bad guys (virus) who grew up together quite happily. Until one day, the good guys realized that these other guys are not from amongst us, let’s kill them. There is a battle and then there is collateral damage. What I want to understand is, if the bad guys aren’t harming the good guys, then why does the body start fighting them? And what is the purpose of their existence if they are not bad guys by default? Perhaps one day someone will help answer my questions. Until then, I’ll try to focus on the inevitable fight.
