How To Treat Hepatitis B Virus

Should I Be Screened For Hepatitis B

Hepatitis B: Treatment and care for a chronic condition

Screening is testing for a disease in people who have no symptoms. Doctors use blood tests to screen for hepatitis B. Many people who have hepatitis B dont have symptoms and dont know they are infected with hepatitis B. Screening tests can help doctors diagnose and treat hepatitis B, which can lower your chances of developing serious health problems.

Your doctor may recommend screening for hepatitis B if you9,14

  • are pregnant
  • were born in an area of the world where 2 percent or more of the population has hepatitis B infection, which includes Africa, Asia, and parts of the Middle East, Eastern Europe, and South America
  • didnt receive the hepatitis B vaccine as an infant and have parents who were born in an area where 8 percent or more of the population had hepatitis B infection, which includes sub-Saharan Africa and parts of Asia
  • are HIV-positive
  • are a man who has sex with men
  • have lived with or had sex with a person who has hepatitis B
  • have an increased chance of infection due to other factors

What Is Hepatitis B

Hepatitis B is an infection of your liver. Itâs caused by a virus. There is a vaccine that protects against it. For some people, hepatitis B is mild and lasts a short time. These âacuteâ cases donât always need treatment. But it can become chronic. If that happens, it can cause scarring of the organ, liver failure, and cancer, and it even can be life-threatening.

Itâs spread when people come in contact with the blood, open sores, or body fluids of someone who has the hepatitis B virus.

It’s serious, but if you get the disease as an adult, it shouldnât last a long time. Your body fights it off within a few months, and youâre immune for the rest of your life. That means you can’t get it again. But if you get it at birth, itâ unlikely to go away.

âHepatitisâ means inflammation of the liver. There are other types of hepatitis. Those caused by viruses also include hepatitis A and hepatitis C.

Medical Treatment For Hepatitis A B & C

Treatment for hepatitis A, B, or C is based on which type of hepatitis is present in the bloodstream and the severity of the resulting liver damage. Depending on the results of diagnostic tests, our specialists at NYU Langone may recommend antiviral medication to stop the virus from replicating and protect your liver from further damage.

Approaches By Virus Life Cycle Stage

Viruses consist of a genome and sometimes a few enzymes stored in a capsule made of protein , and sometimes covered with a lipid layer . Viruses cannot reproduce on their own and instead propagate by subjugating a host cell to produce copies of themselves, thus producing the next generation.

Researchers working on such “rational drug design” strategies for developing antivirals have tried to attack viruses at every stage of their life cycles. Some species of mushrooms have been found to contain multiple antiviral chemicals with similar synergistic effects.Compounds isolated from fruiting bodies and filtrates of various mushrooms have broad-spectrum antiviral activities, but successful production and availability of such compounds as frontline antiviral is a long way away. Viral life cycles vary in their precise details depending on the type of virus, but they all share a general pattern:

  • Attachment to a host cell.
  • Release of viral genes and possibly enzymes into the host cell.
  • Replication of viral components using host-cell machinery.
  • Assembly of viral components into complete viral particles.
  • Release of viral particles to infect new host cells.
  • Before cell entry

    This stage of viral replication can be inhibited in two ways:

  • Using agents which mimic the virus-associated protein and bind to the cellular receptors. This may include VAP anti-idiotypicantibodies, natural ligands of the receptor and anti-receptor antibodies.
  • Uncoating inhibitor

    Hepatitis E: Causes, symptoms, and treatment

    The 2016 AASLD guidelines for the treatment of chronic hepatitis B as well as select recommendations from the 2018 AASLD guidance update on the prevention, diagnosis, and treatment of chronic hepatitis B are outlined below and in the Guidelines section.

    Adults with immune-active chronic hepatitis B infection

    Administer antiviral therapy to lower the risk of morbidity and mortality associated with chronic hepatitis B infection.

    The recommended initial agent for adults is PEG-IFN, entecavir, or tenofovir.

    Adults with immune-tolerant chronic hepatitis B infection

    Antiviral therapy is not recommended.

    The AASLD suggests obtaining ALT levels at least every 6 months to monitor for potential transition to immune-active or -inactive chronic hepatitis B.

    For select patients older than 40 years, the AASLD suggests antiviral therapy in the setting of normal ALT levels, elevated HBV DNA , and significant necroinflammation or fibrosis on liver biopsy specimens.

    Adults with HBeAg-positive immune-active chronic hepatitis B who seroconvert to anti-HBe on nucleoside analog therapy

    After a period of treatment consolidation , consider discontinuing NA therapy in noncirrhotic HBeAg-positive adults who seroconvert to anti-HBe while on NA treatment. If antiviral therapy is stopped, monitor the patient every 3 months for a minimum of 1 year for recurrent viremia, ALT flares, seroreversion, and clinical decompensation.

    Treatment For Chronic Hbv Infection

    For chronic HBV infection, antiviral medications are available.

    This is not a cure for chronic HBV. However, it can stop the virus from replicating and prevent its progression into advanced liver disease.

    A person with a chronic HBV infection can develop cirrhosis or liver cancer rapidly and without warning. If a person does not have access to adequate treatment or facilities, liver cancer can be fatal within months of diagnosis.

    People with a chronic HBV infection require ongoing medical evaluation and an ultrasound of the liver

    Is There A Cure For Chronic Hepatitis B

    Currently, there is no complete cure for hepatitis B. But when managed properly, those living with the virus can expect to live a normal life. Maintaining a healthy diet and avoiding alcoholic beverages and tobacco products are crucial components in managing the disease.

    You should also visit a doctor familiar with hepatitis B at least annuallythough twice a year might be best to monitor your liver through blood tests and medical imaging. As with most diseases, detecting it early leads to a better outcome. If youre exposed to the virus, you should get an antibody injection within 12 hours of exposure.

    How Is Hepatitis B Treated

    Your healthcare provider will treat you based on what type of hepatitis B you have, acute or chronic.

    Acute hepatitis B infections

    If you develop an acute form of the condition, you probably wont need medical treatment. Instead, your doctor will likely suggest that you get plenty of rest, drink lots of fluids and maintain a healthy diet to support your body as it fights off the infection.

    Chronic hepatitis B infections

    If you have chronic hepatitis B, you might be a candidate for drug therapy. Usually, drug therapy is used only if you have active liver disease. There are seven drugs that are approved by the U.S. Food and Drug Administration to treat hepatitis B. Two are injectable forms of interferon, while the five other antivirals are tablets.

    You will need to take these medications every day. They help by slowing the viruss ability to multiply in your system. This helps reduce swelling and liver damage. Youll need to be regularly monitored for early signs of liver damage and liver cancer. Your healthcare provider will want to see you once or twice a year.

    How is HBV transmitted?

    HBV is transmitted through activities that involve percutaneous or mucosal contact with infectious blood or body fluids , including

    • sex with an infected partner
    • injection-drug use that involves sharing needles, syringes, or drug-preparation equipment
    • birth to an infected mother
    • contact with blood from or open sores on an infected person
    • exposures to needle sticks or sharp instruments and
    • sharing certain items with an infected person that can break the skin or mucous membranes , potentially resulting in exposure to blood.

    How long does HBV survive outside the body?

    HBV can survive outside the body and remains infectious for at least 7 days .

    What should be used to clean environmental surfaces potentially contaminated with HBV?

    Any blood spills should be disinfected using a 1:10 dilution of one part household bleach to 10 parts of water. Gloves should be worn when cleaning up any blood spills.

    Who is at risk for HBV infection?

    The following populations are at increased risk for becoming infected with HBV:

    • Infants born to infected mothers
    • Sex partners of infected people
    • Men who have sex with men
    • People who inject drugs
    • Household contacts or sexual partners of known people with chronic HBV infection
    • Health-care and public-safety workers at risk for occupational exposure to blood or blood-contaminated body fluids
    • Hemodialysis patients

    Who should be screened for HBV?

    CDC recommends that the following people be screened for HBV :

    • fever,

    Hepatitis B In The United States

    In the United States, about 862,000 people have chronic hepatitis B.6 Asian Americans and African Americans have higher rates of chronic hepatitis B than other U.S. racial and ethnic groups.10 Researchers estimate that about half of the people living with chronic hepatitis B in the United States are Asian Americans and Pacific Islanders.11 Chronic hepatitis B is also more common among people born in other countries than among those born in the United States.7

    The hepatitis B vaccine has been available since the 1980s and, in 1991, doctors began recommending that children in the United States receive the hepatitis B vaccine. The annual rate of acute hepatitis B infections went down 88.5 percent between 1982 and 2015.12 In 2017, the annual number of hepatitis B infections rose in some states.13 Experts think the rise was related to increases in injection drug use. Injection drug use increases the risk of hepatitis B infection.

    History And Physical Exam

    To diagnose hepatitis, first your doctor will take your history to determine any risk factors you may have for infectious or noninfectious hepatitis.

    During a physical examination, your doctor may press down gently on your abdomen to see if theres pain or tenderness. Your doctor may also feel to see if your liver is enlarged. If your skin or eyes are yellow, your doctor will note this during the exam.

    Hepatitis B Vs Hepatitis C

    Hepatitis has many different types. HBV and the hepatitis C virus have both acute and chronic forms.

    The main difference between HBV and HCV is how they spread from person to person. Although HCV is transmissible via sexual activity, this is rare. HCV usually spreads when blood that carries the virus comes into contact with blood that does not.

    How To Prevent Hepatitis B

    Hepatitis B is a liver infection caused by a virus . It can be serious and theres no cure, but the good news is its easy to prevent. You can protect yourself by getting the hepatitis B vaccine and having safer sex. If you have oral, anal, and vaginal sex, use condoms and dental dams to help stop the spread of hepatitis B and other STDs.

    Hepatitis B Surface Antigen Test

    A hepatitis B surface antigen test shows if youre contagious. A positive result means you have hepatitis B and can spread the virus. A negative result means you dont currently have hepatitis B. This test doesnt distinguish between chronic and acute infection. This test is used together with other hepatitis B tests to determine the .

    What Determines Whether A Patient With Chronic Hepatitis B Needs Treatment

    Hepatitis B drugs are recommended for patients with very active virus and an inflamed liver. These patients will have a very high amount of hepatitis B virus in their blood and an unusually high level of a chemical known as ALT, which is one of the “liver enzymes” that helps the liver do its work. People with cirrhosis also may be candidates for treatment.

    Over time, patients can go through different phases with their hepatitis B. A patient can have a low amount of virus and normal level of ALT for many years, prolonged periods of high viral loads and ALT levels, or short bursts of high viral activity that later subside. It is important to use hepatitis B treatments during phases of high viral activity and prolonged liver inflammation. Your provider will track the phase of hepatitis B by the results of blood tests. So, it is recommended that people with hepatitis B have blood tests on a regular basis.

    For the small percentage of patients who have chronic hepatitis B and also have chronic hepatitis C, when it comes time to be treated with medication for the hepatitis C virus, the hepatitis C medications can cause the hepatitis B virus to flare. In order to prevent this from happening, these patients will need to take hepatitis B treatment at the same time that they take the hepatitis C virus medications.

    How Do You Get Hepatitis B

    Research coalition issues plan for curing hepatitis B virus

    Hepatitis B is really contagious. Its transmitted through contact with semen , vaginal fluids, and blood. You can get it from:

    • having vaginal, anal, or oral sex

    • sharing toothbrushes and razors

    • sharing needles for shooting drugs, piercings, tattoos, etc.

    • getting stuck with a needle that has the Hep B virus on it.

    Hepatitis B can also be passed to babies during birth if their mother has it.

    Hepatitis B isnt spread through saliva , so you CANT get hepatitis B from sharing food or drinks or using the same fork or spoon. Hepatitis B is also not spread through kissing, hugging, holding hands, coughing, sneezing, or breastfeeding.

    How Can I Avoid Getting Hepatitis B

    There is a safe and effective vaccine that can protect you from getting hepatitis B. The vaccine is usually given in three doses over a six month period. The vaccine will give you long-lasting protection. A combined vaccine for hepatitis A and hepatitis B is also available.

    Other ways to protect yourself or your loved ones include:

    • Adopt safe sex practices.
    • Avoid sharing personal hygiene items
    • If you have been exposed to the hepatitis B virus , an injection of hepatitis B immune globulin may help protect you.
    • If you are pregnant, make sure you are screened for hepatitis B. If the test result shows that you have the virus, make sure your baby receives the free hepatitis B vaccine. If you have hepatitis B, breastfeeding is safe if the baby has received both protective antibody called immune globulin, and the first dose of hepatitis B vaccine within the first 12 hours of life. Talk to your doctor about having your newborn immunized .
    • If you decide to have a tattoo, piercing, manicure or pedicure, ensure that the facility uses single-use needles and inks and/or follows proper sterilization procedures.

    Hepatitis B During Pregnancy

    If a woman with HBV becomes pregnant, they may transmit the virus to their baby. Women should inform the doctor who delivers their baby that they have HBV.

    The infant should receive an HBV vaccine and HBIG with 1224 hours of birth. This significantly reduces the risk that they will develop HBV.

    The HBV vaccine is safe to receive while pregnant.

    People with a high risk of HBV include:

    • the infants of mothers with HBV
    • the sexual partners of people with HBV
    • people who engage in sexual intercourse without contraception and those who have multiple sexual partners
    • men who have sex with men
    • people who inject illicit drugs
    • those who share a household with a person who has a chronic HBV infection
    • healthcare and public safety workers who are at risk of occupational exposure to blood or contaminated bodily fluids
    • people receiving hemodialysis, which is a type of kidney treatment
    • people taking medications that suppress the immune system, such as chemotherapy for cancer
    • those who come from a region with a high incidence of HBV
    • all women during pregnancy

    People can prevent HBV infection by:

    • wearing appropriate protective equipment when working in healthcare settings or dealing with medical emergencies
    • not sharing needles
    • following safe sexual practices
    • cleaning any blood spills or dried blood with gloved hands using a 1:10 dilution of one part household bleach to 10 parts water

    A vaccine against HBV has been available since 1982.

    People who should receive this vaccine include:
