Treatment Of Acute Hepatitis B
For fulminant hepatitis B, antiviral drugs and liver transplantation
No treatments attenuate acute viral hepatitis, including hepatitis B. Alcohol should be avoided because it can increase liver damage. Restrictions on diet or activity, including commonly prescribed bed rest, have no scientific basis.
Viral hepatitis should be reported to the local or state health department.
How Long Can You Live With Hepatitis B
Most people who contract hepatitis B during adulthood fully recover within 1 to 3 months.
People with chronic hepatitis B may have a higher risk of developing long-term liver problems, like cirrhosis or liver cancer, which require treatment and may be life threatening.
Keep in mind that the risk of developing chronic hepatitis B is higher for babies and children, especially if they have not been vaccinated against the virus.
How To Help Stop The Spread Of Hepatitis B
There are several things you can do to help stop the spread of this disease. Please follow these instructions until your doctor tells you the child with hepatitis is completely well:
- Good hand washing by all family members must be done. Hands should be washed using soap and warm water before meals, after using the bathroom and before preparing or serving food.
- Wash your hands after caring for your child. You may have come in contact with the hepatitis B virus from such things as changing diapers, cleaning up vomit, or exposure to blood.
- Wear disposable gloves when handling blood . Wash your hands after removing the gloves.
- Hepatitis B can be spread by sexual activity. Not having sex is the best way to keep Hepatitis B from being spread sexually. If an infected person has sex, a condom should be used every time. Condoms should be used until the doctor says there is no longer any risk of spreading the disease.
- All family members who are not infected should get Hepatitis B vaccines .

Complications Of Hepatitis B
A small proportion of people who become infected with the hepatitis B virus develop a long-term hepatitis B infection. They may have the virus in their bloodstream for most of their life without realising they are infected.
People with chronic hepatitis B infection may not notice any health problems until they develop liver problems such as liver disease or liver cancer later in life. Treatment for hepatitis B is essential because it is not possible to be a healthy carrier of the hepatitis B virus. Chronic hepatitis B infection occurs more commonly in some communities, including:
- Aboriginal and Torres Strait Islander communities.
- In people from parts of the world where hepatitis B is more common, such as:
- North-East Asia
- Sub-Saharan Africa.
What Causes Hepatitis D
The hepatitis D virus causes hepatitis D. The hepatitis D virus spreads through contact with an infected persons blood or other body fluids. Contact can occur by
- sharing drug needles or other drug materials with an infected person
- having unprotected sex with an infected person
- getting an accidental stick with a needle that was used on an infected person
The hepatitis D virus rarely spreads from mother to child during birth.
You cant get hepatitis D from
- being coughed on or sneezed on by an infected person
- drinking water or eating food
- hugging an infected person
- shaking hands or holding hands with an infected person
- sharing spoons, forks, and other eating utensils
- sitting next to an infected person

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.
Prevent Infection After Contact With The Virus
If you think you have been in contact with the hepatitis B virus, see your doctor right away. Doctors typically recommend a dose of the hepatitis B vaccine to prevent infection. In some cases, doctors may also recommend a medicine called hepatitis B immune globulin to help prevent infection. You must get the vaccine dose and, if needed, HBIG shortly after coming into contact with the virus, preferably within 24 hours.

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 beverages that contain alochol and tobacco products are crucial components in managing the disease.
You should also visit a doctor familiar with hepatitis B at least annually though 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.
What Are The Symptoms Of Hbv
Hepatitis B virus can cause an acute illness with symptoms that last several weeks, including yellowing of the skin and eyes , dark urine, extreme fatigue, nausea, vomiting and abdominal pain. Most of the time HBV infection is ASYMPTOMATIC.
Joint pains, muscle aches, rash, and jaundice may occur in some people. People can take several months to a year to recover from the symptoms. These people may not know that they are infected, and may therefore not go and see a doctor. People with chronic hepatitis B infection may later develop serious problems like liver cancer and liver failure. These people may not know that they are infected, and may therefore not go and see a doctor. People with chronic hepatitis B infection may later develop serious problems like liver cancer and liver failure.

Why It Is Used
Hepatitis B virus causes a liver infection that can lead to serious complications, including liver cancer. It is common in people throughout the world, particularly in Asia and sub-Saharan Africa.
The Canadian National Advisory Committee on Immunization recommends hepatitis B immunization for all children. Pregnant women and other adults who do not have immunity and who have a high chance of exposure should be vaccinated.
Hepatitis D Coinfection With Hepatitis B
Hepatitis D virus the D is for delta is a viral enigma that doesnt act like a normal virus. It is helpless that is, it cant infect a cell without its viral accomplice, the hepatitis B virus , and makes infection with HBV worse.
Delta virus can only cause illness in those already infected with HBV, said Timothy Block, Ph.D., President and Co-Founder of the Hepatitis B Foundation, Professor and Director, Drexel University Institute for Biotechnology and Virology Research.
It can take quiescent HBV and turn it into an acute, lethal viral infection, Block said. Liver disease cirrhosis, liver failure that might take decades to develop or could only take a year or two. Delta virus converts HBV infection into an emergency situation.
Its one of the most severe forms of human viral hepatitis, said Jeffrey Glenn, MD, Ph.D., Associate Professor of Medicine at Stanford Cancer Institute.
Delta virus is a parasite of HBV because it encodes its own genome and coat-like protein but it doesnt make its own envelope protein, Glenn explained. It steals that from HBV. It needs the B envelope protein to make its own, and this provides a means to infect new cells and subsequently make a fully formed viral particle to get out of those cells to infect others.
Hepatitis D Fast facts:
Delta hepatitis is one of the most severe forms of viral hepatitis.
It is an incomplete viral particle that was discovered in 1977.

How Is Hepatitis B Prevented
Testing & Vaccination
- The hepatitis B vaccine offers excellent protection against HBV. The vaccine is safe and highly effective. Vaccination consists of 3 doses of vaccine over the course of 6 months. Protection lasts for 20 years to life.
- The American Academy of Pediatrics recommends that all children should receive hepatitis B vaccine starting at birth. .
- The CDC recommends hepatitis B vaccine for persons traveling to countries where HBV is common .
- If you have one or more risk factors for hepatitis B infection, you should get a simple HBV blood test. The blood test will determine whether you are:
- immune to hepatitis B or
- susceptible to hepatitis B and need vaccination or
- infected with hepatitis B and need further evaluation by a physician
- California law requires testing of all pregnant women for hepatitis B infection
- If the mother is HBV-infected, she will pass the infection to the baby during the birth process, unless the baby gets immunized within hours of birth
- Giving the infant HBIG and HBV vaccine right away will reliably prevent infection of the infant
- Other family members should best tested for hepatitis B too, and given vaccine if they are not already infected or immune
After Exposure to Hepatitis B
How Common Is It
In 2006, the Public Health Agency of Canada reported the incidence of HBV as 2.0 cases for every 100,000 or about 650 cases reported annually in Canada. In the year 2013, the incident rate was 0.5 per 100,000 . Incidence of the disease varies from region to region but has been declining due to increasing use of the vaccine and universal immunization programs.

Active Vaccination To Prevent Infection
Hepatitis B vaccination is available for preexposure and postexposure prophylaxis and provides long-term protection. Hepatitis B vaccines are produced recombinantly in yeast cell systems. The vaccines contain noninfectious HBsAg , a small amount of yeast protein, and aluminum hydroxide as an adjuvant. Pediatric formulations contain trace or no thimerosal. Administration is via the intramuscular route. Adverse effects are generally mild and mainly consist of local tenderness and low-grade fever. After a vaccine series, more than 95% seroconversion is achieved, which results in > 90% efficacy. Studies are ongoing to determine length of immunity, but it is at least 20 years.
Two hepatitis B single antigen vaccines are available in the United States: Recombivax from Merck & Co. and Engerix-B from GlaxoSmithKline. Both vaccines come in doses for pediatric and adult populations. High-dose vaccines are available for adult hemodialysis and immunocompromised patients. Both vaccines are given in a three-dose series and are generally interchangeable. A fourth dose may be given if a birth dose was administered. The birth dose must be a single antigen formulation.
Booster doses of hepatitis B vaccine beyond the initial series are generally not recommended. The long incubation period of hepatitis B theoretically allows for the development of a protective anamnestic immune response after exposure.

Is Hepatitis B Contagious
Hepatitis B is highly contagious. Its transmitted through contact with blood and certain other bodily fluids. Although the virus can be found in saliva, its not transmitted through sharing utensils or kissing. Its also not transmitted through sneezing, coughing, or breastfeeding.
Symptoms of hepatitis B may not appear for 3 months after exposure. Symptoms can last for several weeks.
But even without symptoms, you can still transmit the infection to others. The virus can live outside the body and remains infectious for at least
Hepatitis B is a highly contagious condition. Its associated with many serious complications, some of which can be life threatening.
But there are many treatment options available and multiple ways you can prevent infection, including getting vaccinated.
If you suspect you may have been exposed to hepatitis B, its important to talk with a doctor to prevent infection and determine the best course of treatment for you.

Pearls And Other Issues
Hepatitis D has been long associated with HBV infections and cannot exert pathological influence without the presence of HBV infection. Two forms of infection exist coinfection and superinfection . Superinfection tends to be more severe than coinfection. Due to the preexisting hepatitis B infection, anti-HBcAg IgM is undetectable in superinfection states but can be noted in coinfection.
Acute Hepatitis B Symptoms
There are three phases of acute hepatitis B infection, and symptoms may differ depending on the stage. Early in the disease, called the prodromal phase, symptoms may include:
- Dark urine and light stool color
During the icteric phase:
- Jaundice develops
- Anorexia, nausea and vomiting may worsen
- Irritated skin lesions may develop
- Other symptoms may subside

What Are The Signs And Symptoms Of Hepatitis B
Many individuals who are acutely infected with hepatitis B virus may not experience any signs or symptoms of their infection. Most others may experience very mild symptoms that can be mistaken for the flu, such as fever, fatigue, loss of appetite, and nausea and vomiting. More severe symptoms include abdominal pain, dark urine, joint pain, jaundice , and clay-colored bowel movements. These symptoms usually occur within the first six months of infection.
Individuals who become chronically infected with hepatitis B may be asymptomatic for many years or decades. However, damage may be occurring to their livers, which could ultimately lead to cirrhosis or liver cancer.
Genetics Of Infection With Hepatitis B
Several genes, many having to do with the host immune response, have been implicated in the susceptibility to chronic hepatitis B infection. The TNFSF9 gene encodes the CD137L protein, and its expression was found to be significantly higher in patients with chronic hepatitis B infection than in healthy controls. Its expression was also found to be higher in patients who had chronic hepatitis B with cirrhosis, in contrast to those without cirrhosis.
Research done in West Africa, where 90% of the population is infected with hepatitis B, shows that certain human leukocyte antigen class II haplotypes influence the likelihood of chronic infection. For reasons that are not completely clear, patients in the study who were heterozygous for the HLA-DRA and HLA-DQA1 genes were found to be less likely to develop a chronic infection.
Several additional genes are associated with susceptibility to hepatitis B infection. The IFNGR1 gene is located at 6q23.3 and encodes the interferon gamma receptor 1, which has an important role in cell-to-cell communications and can be activated in response to infection, but it is not specific to hepatitis B. Patients with significant dysfunction in this gene have a particular immune deficiency that leaves them extremely susceptible to mycobacterial infections.

What Is The Treatment For Hepatitis B
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.
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
