Ignore it till it goes away! A hepatitis B vignette.

The Scenario:

Woman is sick on couch, her husband is giving her an ice pack

Aroha Kawai just started a new job as a medical interpreter for Pacific Islander patients diagnosed with COVID-19. As a critical source of communication for the providers and the patients, she is often called to work night and weekend shifts. Aroha had a difficult conversation with the family members of a critical COVID-19 patient on whether they should discontinue ventilation support for the ailing grandmother. During this time, Aroha’s family noticed changes in her behavior. She stopped eating regularly, lost weight and repeatedly cancelled plans to go out. Aroha dismissed her family’s concerns as physical manifestations of the emotional burnout from work.

People are at a free hepatitis B screening event in a park.

Recently she attended a health fair hosted by her department at work. She approached a viral hepatitis screening booth and decided to get tested for hepatitis B. The following week, she received her results in the mail. Her results indicated that she had tested positive for hepatitis B. She shared her diagnosis with her mother who informed her that her grandfather died from liver cancer.  

Inside a doctor's office. A doctor is showing information about the liver. A woman with hepatitis B sits with her husband.

Aroha then followed up with her primary care doctor.  She discovered that she had chronic hepatitis B. Even though the ultrasound did not show any evidence of cirrhosis, her doctor ordered an imaging test (U/S, CT, MRI) to screen for liver cancer. Unfortunately, Aroha was diagnosed with early-stage liver cancer.  

Inside a hospital room. A man and child visit a woman with hepatitis B in a hospital bed.

Fortunately, the cancer had not spread and did not infect nearby blood vessels. Her doctor suggested a partial hepatectomy to remove the tumor safely as the rest of the liver was still healthy. Aroha decided to adhere to her doctor’s advice and successfully underwent the surgery. She has taken some time off from work to focus on recuperating from the surgery and spending time with loved ones.  

 

 

The Challenge:
  1. Dismissal of Symptoms:
    • Aroha initially ignored the physical symptoms of liver cancer. It is true that signs and symptoms may not necessarily be present.
    • However, it is crucial to take care of one’s health and never ignore warning signs. Fatigue, unintended weight loss, and loss of appetite are a few of the symptoms of liver cancer. 
  2. Cancer without Cirrhosis: 
    • It is possible to get liver cancer without cirrhosis. Therefore, it is always important to screen for liver cancer if you have chronic hepatitis B infection. 
  3. Importance of Screening
    • Liver cancer screening is a highly effective method to detect malignant tumors and prevent cancer for those living with hepatitis B.
    • Early intervention increases the survival rate significantly and stops the cancer from spreading to other vital organs. 
What can you do?
  1. Get Help!
    • If you experience pain or discomfort of any kind, it is important to reach out for help. Set up an appointment with your doctor and discuss your concerns.
    • There is a good chance you might be misunderstanding an important health issue for side effects of stress or emotional burnout. Do not ignore your symptoms or feelings.  
  2. Get Screened!
    • Hepatitis B is a leading cause of liver cancer, most of the time it is because someone did not know they were infected with hepatitis B or were not managing their hepatitis B infection.
    • Everyone should be tested for hepatitis B to know their status. Ask your doctor for a hepatitis B screening today.  
  3. Stay on track!
    • If you have hepatitis B, it is critical to manage the progression of the virus in your liver. For this reason, it is important to go through liver cancer surveillance regularly. Discuss with your doctor if you are at high-risk and how often you should get screened.
    • It is recommended to get an ultrasound with blood work every 6 months to check how the virus is impacting the liver.  This includes the alpha-fetoprotein (AFP) blood test to measure the levels of AFP in your blood as it may indicate the presence of cancer cells in your liver. This can also help detect any scarring or tumors. 

Don't ignore it until it goes away. Get help. Get screened for hepatitis B. Stay on track.

Reactivation with Hepatitis B: Understanding Risk Factors and Prevention Strategies

Understanding the hepatitis B virus and the panel of blood tests needed to determine infection or immunity can be a stressful and challenging task. In simplest terms, “hepatitis” means liver inflammation and the hepatitis B virus can ultimately cause liver inflammation. The liver is an important organ in the human body and responsible for the removal of toxins and regulation of digestion (learn more about the function of the liver here). The hepatitis B virus can infect and disrupt critical functions of the liver in supporting your overall health. 

How the hepatitis B virus works 

In the case of the hepatitis B virus, the host is the liver cell. As the virus makes more copies of itself, the liver may become damaged, and sometimes it is unable to carry out its essential tasks to regulate metabolism, nutrients, and digestion. It is best to prevent hepatitis B infections when we can – and since antibodies are the best defense against the virus, the hepatitis B vaccine can be used to signals the body to make antibodies to fight the virus. The hepatitis B vaccine provides lifelong protection from the virus. However, this is only possible before infection with the virus. If somebody is already infected with the virus, antiviral therapy is used to control the virus and prevent liver damage – antiviral medications disrupt the life cycle of the virus by disabling viral receptors from binding to liver cells. 

Blood test panel to diagnose hepatitis B: 

The only way to tell someone’s hepatitis B status is through a panel of blood tests – the tests are all done at one time, and only one small tube of blood is needed. These tests are not included in routine testing, so it is important to ask your doctor to test you for hepatitis B or try to find a free screening event near you (http://www.hepbunited.org/). The panel consists of the following tests to determine your hepatitis B status: 

  1. HBsAg: 
    • This tests for the hepatitis B surface antigen in someone’s blood. The surface antigen is the protein that surrounds the virus and protects it from attack by the host. A positive surface antigen test indicates that the virus is present in the body. A “positive” or “reactive” result for HBsAg indicates that someone is infected with hepatitis B and can transmit the virus to others.  
  1. HBsAb 
    • This tests for the hepatitis B surface antibody in someone’s blood. The surface antibodies are produced by the immune system and can fight off the virus by attaching to the surface antigen protein. This test can detect the presence of these antibodies. Ideally this test will be ordered quantitatively (numerically). A “positive” surface antibody test (meaning numbers reading >10 IU/mL) means that a person has protection against the hepatitis B virus (either by vaccine or from a past exposure).  
  1. HBcAb (total) 
    • This is known as the hepatitis B core antibody test. The core antibody is produced by the immune system after infection with the virus. This test indicates an existing or past infection of the hepatitis B virus.

Important things to know about Hepatitis B Core Antibody (HBcAb) 

Someone who has markers of past infection, particularly hepatitis B core antibody, can be at risk for hepatitis B reactivation. Reactivation can be triggered by immunosuppressive therapies and cause significant life-threatening challenges. If you test HBcAb+, please talk to your doctor about what that means, and make sure you notify all future health care providers. 

How is reactivation with HBV defined? 

Reactivation is defined as the sudden increase or reappearance of HBV (hepatitis B virus) DNA. When the virus invades the cell, it forms a covalently closed circular DNA (cccDNA) in the nucleus of infected cells referred to as hepatocytes. Because cccDNA is resistant to antiviral treatments, it is never removed from the cells. Therefore, even after recovery from a past infection, the cccDNA is present and may reactivate. It is not clearly understood why this may happen, but certain factors may increase the risk for reactivation.

What puts one at risk for reactivation? 

  1. Virologic factors such as high baseline HBV DNA, hepatitis B envelope antigen positivity (HBeAg), and chronic hepatitis B infection that persists for more than 6 months.
    • Detectable HBV DNA levels and detectable levels of HBsAG can increase the risk for HBRr (reactivation) 
    • Testing positive for HBeAg also increases the risk for reactivation 
  2. Co-infection with other viruses such as hepatitis C or hepatitis Delta 
  3. Older age 
  4. Male sex 
  5. Cirrhosis 
  6. An underlying condition requiring immunosuppressive therapies (rheumatoid arthritis, lymphoma, or solid tumors) 
    • Certain medications can increase the likelihood of reactivation by more than 10%.  
    • B-cell depleting agents such as rituximab, ofatumumab, doxorubicin, epirubicin, moderate or high-dose corticosteroid therapy lasting more than 4 weeks. 

How to prevent reactivation of hepatitis B 

Hepatitis B reactivation is a serious condition that can lead to health complications, Reactivation is avoidable if at-risk individuals are identified through screening. Current guidelines recommend that individuals at the highest risk (those receiving B-cell depleting therapies and cytotoxic regimens) should receive antiviral therapies as prophylaxis before beginning immunosuppressive therapy. These antiviral therapies should also be continued well beyond stopping the immunosuppressive therapies. Be sure to talk to your doctor to be sure you are not at risk for reactivation.
