Hepatitis B Is Caused By What

What Is The Treatment For Hepatitis B

Hepatitis B Can Cause Liver Damage, Cancer

Prevention is recommended by receiving a vaccine for HBV.

Receiving an injection of the hepatitis B immune globulin within 12 hours of coming in contact with the virus may help prevent the development of the disease.

At present, there is no specific treatment for patients with acute hepatitis B. Acute infection is usually short and will often resolve on its own. Your health care provider may recommend rest, and adequate nutrition and fluids to help your body fight the infection. Hospitalization may be required for patients who suffer from severe vomiting and who are unable to maintain adequate nutritional levels. It may also be required to prevent the development of complications.

While chronic infection cannot be cured, there are two standard treatments in Canada that may control the virus and prevent further damage to the liver.

  • Antiviral medications can fight the virus and slow damage to the liver.
  • Interferon which may be given for short periods and if effective, results in suppression of the virus.

What Makes Yale Medicines Approach To Treating Hepatitis B And C Unique

The Viral Hepatitis Program at Yale Medicine represents one of the leading viral hepatitis treatment programs in the country and is engaged in innovative research focused on advancing the care of patients with chronic hepatitis B, C and D infections.

A multidisciplinary team of faculty physicians and mid-level providers offer a coordinated approach to preparing patients for success. Services include structured hepatitis patient education classes, mindfulness-based stress reduction techniques , a formal physician-guided weight-loss program and access to clinical trials evaluating current and new therapies that are not available in routine clinical practice.

Our program is a core member of several national and international observational cohort studies which contributes to the advancement of science of hepatitis treatment around the world.

Our team at Yale Medicine is uniquely equipped to serve patients with viral hepatitis from Connecticut and beyond and aims to offer outstanding, individualized, patient-centered care to help educate and guide patients through their treatment, says Dr. Lim. We have specialists who have nationally recognized expertise in the management of viral hepatitis in special populations, including HCV-HIV coinfection, end-stage renal disease, cirrhosis/liver failure, post-liver transplant, and prior failure to respond to all-oral direct acting antivirals .

Key Facts About Hepatitis B

  • Hepatitis B is a liver infection capable of causing both short-term and long-term disease.
  • The virus is contracted through blood or body fluids of someone who is infected.
  • The virus is up to 100 times more infectious than HIV.
  • Two thirds of people who have caught Hepatitis B virus remain unaware of their infection.
  • Every year more than 780,000 fatalities are registered due to complications caused by hepatitis B such as cirrhosis and liver cancer.
  • Hepatitis B is a major occupational hazard for health care professionals.
  • It is possible to prevent the disease by taking a safe and effective vaccine.

What Is Chronic Hepatitis B

Doctors refer to hepatitis B infections as either acute or chronic:

  • An acute HBV infection is a short-term illness that clears within 6 months of when a person is exposed to the virus.
  • A person who still has HBV after 6 months is said to have a chronic hepatitis B infection. This is a long-term illness, meaning the virus stays in the body and causes lifelong illness. An estimated 850,000 to more than 2 million people in the U.S. have chronic HBV.

The younger someone is when infected, the greater the chances for chronic hepatitis B.

Treatment For Suspected Exposure

Anyone who has had potential exposure to HBV can undergo a postexposure prophylaxis protocol.

This consists of HBV vaccination and hepatitis B immunoglobin . Healthcare workers give the prophylaxis after the exposure and before an acute infection develops.

This protocol will not cure an infection that has already developed. However, it decreases the rate of acute infection.

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.

Take Precautions To Avoid Hbv

Other ways to reduce your risk of HBV include:

  • Know the HBV status of any sexual partner. Don’t engage in unprotected sex unless you’re absolutely certain your partner isn’t infected with HBV or any other sexually transmitted infection.
  • Use a new latex or polyurethane condom every time you have sex if you don’t know the health status of your partner. Remember that although condoms can reduce your risk of contracting HBV, they don’t eliminate the risk.
  • Don’t use illegal drugs. If you use illicit drugs, get help to stop. If you can’t stop, use a sterile needle each time you inject illicit drugs. Never share needles.
  • Be cautious about body piercing and tattooing. If you get a piercing or tattoo, look for a reputable shop. Ask about how the equipment is cleaned. Make sure the employees use sterile needles. If you can’t get answers, look for another shop.
  • Ask about the hepatitis B vaccine before you travel. If you’re traveling to a region where hepatitis B is common, ask your doctor about the hepatitis B vaccine in advance. It’s usually given in a series of three injections over a six-month period.

What Are The Complications Of Hepatitis B

The course of hepatitis B infection depends mostly on the age at which a person is infected.

People infected as infants are likely to develop long term infection and can get complications such as scarring of the liver or liver cancer. Infants have a 9 in 10 chance and children have a 3 in 10 chance of developing a chronic, lifelong infection.

People infected as teenagers or adults are likely to become unwell with symptoms , but have a smaller chance of developing a chronic infection. Others develop a silent infection, without any symptoms.

Most people infected as adults clear the virus from the body within 6 months. They develop immunity to future hepatitis B infections and do not develop long-term liver damage.

However, approximately 1 in 20 adults cannot clear the virus and develop chronic hepatitis B. They are at risk of developing complications such as cirrhosis and liver cancer in the longer term.

Who Is Most Affected

In the United States, rates of new HBV infections are highest among adults aged 30-59 years, reflecting low hepatitis B vaccination coverage among adults at risk. The most common risk factor among people with new HBV infections is injecting drugs, related to the opioid crisis.

The highest rates of chronic hepatitis B infection in the United States occur among foreign-born individuals, especially people born in Asia, the Pacific Islands, and Africa. Approximately 70% of cases in the United States are among people who were born outside of the United States. CDC developed this map of the geographic distribution of hepatitis B around the world – PDF. Other groups who have higher rates of chronic HBV infection include people who inject drugs and men who have sex with men.

About The Hepatitis B Virus

The hepatitis B virus is a small DNA virus that belongs to the Hepadnaviridae family. Related viruses in this family are also found in woodchucks, ground squirrels, tree squirrels, Peking ducks, and herons.

Structure of the Hepatitis B Virus The hepatitis B virus contains an outer envelope and an inner core.

  • The outer envelope of the virus is composed of a surface protein called the hepatitis B surface antigen or “HBsAg”. The HBsAg can be detected by a simple blood test and a positive test result indicates a person is infected with the hepatitis B virus.
  • The inner core of the virus is a protein shell referred to as the hepatitis B core antigen or “HBcAg,” which contains the hepatitis B virus DNA and enzymes used in viral replication.

Life Cycle of the Hepatitis B Virus

The hepatitis B virus has a complex life cycle. The virus enters the host liver cell and is transported into the nucleus of the liver cell. Once inside the nucleus, the viral DNA is transformed into a covalently closed circular DNA , which serves as a template for viral replication . New HBV virus is packaged and leaves the liver cell, with the stable viral cccDNA remaining in the nucleus where it can integrate into the DNA of the host liver cell, as well as continue to create new hepatitis B virus. Although the life cycle is not completely understood, parts of this replicative process are error prone, which accounts for different genotypes or genetic codes of the hepatitis B virus.

What Is The Outlook For People With Hepatitis B

The outlook for people with HBV is better now than ever before. You are certainly able to live a full life and help yourself stay healthy. You should make sure to have regular check-ups with a healthcare provider who is qualified to treat hepatitis B, possibly a liver doctor.

Make sure you are vaccinated against hepatitis A. Check with your healthcare provider or pharmacist before taking other medications or over-the-counter products, including supplements and natural products. These could interfere with your medication or damage your liver. For instance, taking acetaminophen in large doses may harm your liver.

Follow the usual guidelines for living a healthy life:

  • Eat nutritious foods, choosing from a variety of vegetables, fruits and healthy proteins. It is said that cruciferous vegetables are especially good at protecting the liver.
  • Exercise regularly.
  • Dont smoke and dont drink. Both tobacco and alcohol are bad for your liver.
  • Do things that help you cope with stress, like journaling, talking with others, meditating and doing yoga.
  • Avoid inhaling toxic fumes.

Hepatitis B Treatment Is There A Cure

Normally acute Hepatitis B does not require special treatment and the majority of adults clear the virus spontaneously. Early treatment may be required only in less than 1% of infected people who are immunocompromised or whose infection takes an aggressive course.

Its very important to maintain comfort, avoid alcohol, keep to a balanced diet, and replace body fluids lost from diarrhea and vomiting. On the other hand, chronic hepatitis B can be treated with medicines, including antiviral agents. Treatment can help to reduce the risk of cirrhosis and liver cancer.

Chronic Hepatitis B is usually a mild disease among children. Most of them can live full and healthy lives without visible symptoms. However, in some children the virus can cause significant liver damage. They will require medical treatment and intervention. All children suffering from chronic hepatitis B infection should be seen by a liver specialist on a regular basis. During the visits its necessary to take blood tests, physical exams and sometimes ultrasounds of the liver.

How Many People Have Hepatitis B

In the United States, an estimated 862,000 people were chronically infected with HBV in 2016. New cases of HBV infection in the United States had been decreasing until 2012. Since that time, reported cases of acute hepatitis B have been fluctuating around 3,000 cases per year. In 2018, 3,322 cases of acute hepatitis B were reported however, because of low case detection and reporting, the Centers for Disease Control and Prevention estimates that there were 21,600 acute hepatitis B infections. New HBV infections are likely linked to the ongoing opioid crisis in the United States.

Globally, HBV is the most common blood-borne infection with an estimated 257 million people infected according to the World Health Organization .

What Is The Long

Children with chronic hepatitis B can lead completely normal lives, attend school, and play sports without any special arrangements, just like any other child.

A child with chronic HBV infection could be infected for life. Over the decades, the virus can cause progressive damage to the liver and lead to such complications as cirrhosis and liver cancer.

When they become older, children with hepatitis B should avoid drinking alcohol, as it can make the disease progress more quickly. Once they become sexually active, they should practice safe sex to protect their partners from infection.

Hepatitis B: Explained

It is unclear how a liver becomes fatty. The fat may come from other parts of your body, or your liver may absorb an increased amount of fat from your intestine. Another possible explanation is that the liver loses its ability to change fat into a form that can be eliminated. However, the eating of fatty foods, by itself, doesnt produce a fatty liver.

What Are The Treatments For Hepatitis B

If you think you may have been exposed to hepatitis B, its important to talk with a healthcare professional as soon as possible.

A doctor or other healthcare professional may administer the first dose of the hepatitis B vaccine and a shot of hepatitis B immunoglobulin. This is a combination of antibodies that provide short-term protection against the virus.

Though both can be given up to a week after exposure, theyre most effective at preventing infection if administered within 48 hours.

If you receive a diagnosis of acute hepatitis B, a doctor may refer you to a specialist. They may advise you to get regular blood tests to ensure you dont develop chronic hepatitis.

Many people with acute hepatitis B dont experience serious symptoms. But if you do, it can help to:

  • get plenty of rest
  • take over-the-counter pain mediation, like naproxen, when needed

Other lifestyle changes may also be needed to manage your infection, such as:

  • eating a nutritious, balanced diet
  • avoiding substances that can harm your liver, such as:
  • certain herbal supplements or medications, including acetaminophen

If blood tests show you still have an active infection after 6 months, your doctor may recommend further treatment, including medications to help control the virus and prevent liver damage.

How Do People Get The Hbv Virus

Hepatitis B virus is found in the blood of people with HBV infection. It enters the body through blood-to-blood contact.

Reliable blood tests for HBV were developed many years ago. Since blood donors and blood products are tested for HBV, this is no longer the typical means of infection.

In many parts of the world, hepatitis B virus infects more than 8% of the population. HBV-infected women pass the infection to their babies during the birth process. People can also get hepatitis B by sharing needles for injection drug use, through sexual contact with an infected person, by an accidental needlestick with a contaminated needle, or from improperly sterilized medical, acupuncture, piercing, or tattooing equipment.

Who Is More Likely To Get Hepatitis B

People are more likely to get hepatitis B if they are born to a mother who has hepatitis B. The virus can spread from mother to child during birth. For this reason, people are more likely to have hepatitis B if they

  • were born in a part of the world where 2 percent or more of the population has hepatitis B infection
  • were born in the United States, 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

People are also more likely to have hepatitis B if they

  • are infected with HIV, because hepatitis B and HIV spread in similar ways
  • have lived with or had sex with someone who has hepatitis B
  • have had more than one sex partner in the last 6 months or have a history of sexually transmitted disease
  • are men who have sex with men
  • are injection drug users
  • work in a profession, such as health care, in which they have contact with blood, needles, or body fluids at work
  • live or work in a care facility for people with developmental disabilities
  • have been on kidney dialysis
  • live or work in a prison
  • had a blood transfusion or organ transplant before the mid-1980s

In the United States, hepatitis B spreads among adults mainly through contact with infected blood through the skin, such as during injection drug use, and through sexual contact.12
