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.

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.

Hepatitis B: What Happens
Many adults who get hepatitis B have mild symptoms for a short time and then get better on their own. But some people are not able to clear the virus from the body, which causes a long-term infection. Nearly 90% of infants who get the virus will carry it for life. Over time, hepatitis B can lead to serious problems, such as liver damage, liver failure, and liver cancer.
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 .

How Do Doctors Treat Hepatitis B
Doctors typically dont treat hepatitis B unless it becomes chronic. Doctors may treat chronic hepatitis B with antiviral medicines that attack the virus.
Not everyone with chronic hepatitis B needs treatment. If blood tests show that hepatitis B could be damaging a persons liver, a doctor may prescribe antiviral medicines to lower the chances of liver damage and complications.
Medicines that you take by mouth include
A medicine that doctors can give as a shot is peginterferon alfa-2a .
The length of treatment varies. Hepatitis B medicines may cause side effects. Talk with your doctor about the side effects of treatment. Tell your doctor before taking any other prescription or over-the-counter medicines.
For safety reasons, you also should talk with your doctor before using dietary supplements, such as vitamins, or any complementary or alternative medicines or medical practices.
Who Is At Risk For Hepatitis B
Anyone can get hepatitis B, but the risk is higher in
- Infants born to mothers who have hepatitis B
- People who inject drugs or share needles, syringes, and other types of drug equipment
- Sex partners of people with hepatitis B, especially if they are not using latex or polyurethane condoms during sex
- Men who have sex with men
- People who live with someone who has hepatitis B, especially if they use the same razor, toothbrush, or nail clippers
- Health care and public-safety workers who are exposed to blood on the job
- Yellowish eyes and skin, called jaundice
If you have chronic hepatitis B, you may not have symptoms until complications develop. This could be decades after you were infected. For this reason, hepatitis B screening is important, even if you have no symptoms. Screening means that you are tested for a disease even though you donât have symptoms. If you are at high risk, your health care provider may suggest screening.

What Is A Biopsy
A biopsy is a medical procedure. A tiny piece of liver is removed and examined to find out the extent of damage. It involves a large needle and local anesthetic, as well as some risk of bleeding. A pathologist looks at the piece of liver under microscopes to determine how much damage has occurred in the liver. This is a very useful test and used to be done very commonly. However, the procedure is done much less frequently than in the past. For most patients with hepatitis B and C, liver biopsy is not required. Today, other tests can be used to try to estimate the fibrosis in the liver.
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.

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.
Prognosis Improvement After Hbsag Clearance
These related studies provide clear recommendations that patients who achieve HBsAg clearance have favourable clinical outcomes compared to patients who achieve only HBV DNA suppression and HBeAg seroconversion. HBsAg clearance leads to biochemical, virological and liver histological improvements, and it significantly reduces the risk of HCC. However, HCC may occur after HBsAg seroclearance despite it being the ultimate treatment endpoint recommended by current guidelines. The risk factors associated with HCC include the presence of cirrhosis, male sex, and age50 years at the time of HBsAg clearance . Closer attention should be given to patients with one or more of these risk factors.
These high-risk patients should be re-examined in a timely manner even if HBsAg clearance is obtained. These results also suggest that achieving a functional cure early in the absence of cirrhosis results in a better prognosis .

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.
What Are The Symptoms Of Hepatitis B
After the virus enters the body, there is an incubation period lasting 1.5 to 6 months until illness begins. During the acute phase most persons have no symptoms or might experience a mild illness. Symptoms of acute HBV infection, when present, may include:
- Dark-colored urine, light-colored stools
During the chronic phase hepatitis B usually progresses silently, with no symptoms at all during the first 10-20 years. Signs of severe liver scarring may include:
- Star-shaped vein pattern developing on the swollen belly
- Easy bruising and bleeding
Chronic HBV infection can lead to serious liver disease, liver scarring , and hepatocellular cancer.
Because symptoms of hepatitis B are usually absent, persons with risk for HBV infection should be tested. If you think you have hepatitis B, or are at risk for hepatitis B, you should contact your doctor.
