How Do You Get Rid Of Hepatitis B

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.

What Should You Know About Hepatitis B Before You Travel

Hepatitis B is quite common in China and other Asian countries, where as many as 1 in 12 people have the virus, though many dont know it. Before traveling to those places, you should make sure youve been vaccinated against the virus.

In addition to getting the vaccine, you can take these additional precautions to reduce your risk of contracting the virus:

• Refrain from taking illegal drugs.
• Always use latex or polyurethane condoms during sex.
• Make sure new, sterile needles are used during all piercings, tattoos and acupuncture sessions.
• Avoid direct contact with blood and bodily fluids.
• Know the HBV status of all your sexual partners.
• Ask your doctor about possible vaccination before you travel to a place where hepatitis B is common.

A note from Cleveland Clinic

Hepatitis B is a liver disease that can cause serious damage to your health. One reason that is dangerous is that it can easily go undetected for years while damaging your liver. Talk with your healthcare provider about being tested for hepatitis B if you have any reason to believe that you were not vaccinated or if you have engaged in risky behavior. If you do test positive, follow the directions from your healthcare provider so that you can live a longer, healthier and happier life.

How Is Hepatitis B Spread

You can become infected with hepatitis B through exposure to blood, semen and other bodily fluids of an infected person. You can get the infection by:

• Having unprotected sex.
• Sharing or using dirty needles for drug use, tattoos or piercing.
• Sharing everyday items that may contain body fluids, including razors, toothbrushes, jewelry for piercings and nail clippers.
• Being treated medically by someone who does not use sterile instruments.
• Being bitten by someone with the infection.
• Being born to a pregnant woman with the infection.

Hepatitis B is not spread by:

• Kissing on the cheek or lips.
• Coughing or sneezing.
• Hugging, shaking hands or holding hands.
• Eating food that someone with the infection has prepared.
• Breastfeeding.

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:

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.

Are There Ways To Cure Hepatitis C Other Than With Medications

Patients sometimes ask whether there are ways to treat hepatitis C other than taking medicines. Currently, there are no vaccines to prevent hepatitis C. Once a person is infected, the only way to treat it is with prescribed antiviral medications.

Some patients worry that having hepatitis C means they will need a liver transplant. Only a very small fraction of people with hepatitis C require a liver transplant. By far, most people with hepatitis C never need a liver transplant. A transplant is performedonlywhen damage to the liver is extremely advanced and the liver is unable to perform its basic functions. A transplant provides a new working liver, but a transplant does not get rid of the hepatitis C virus in the patient. Patients with a liver transplant still need antiviral medication to cure their virus.

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

• tenofovir disoproxil fumarate

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.

Accessibility And Hbsag Clearance Rate

HBsAg clearance occurs spontaneously or via antiviral treatment in CHB patients. The most commonly used drugs are nucleoside analogue and pegylated interferon . NA drugs include entecavir , tenofovir disoproxil fumarate and tenofovir alafenamide fumarate . The 2018 AASLD guidelines recommend Peg-IFN, ETV, or TDF as the preferred initial therapy for adults with immune-active CHB. It also suggests that alanine transaminase levels be tested at least every 6 months for adults with immune-tolerant CHB to monitor for potential transition to immune-active or immune-inactive CHB . The 2017 EASL guideline recommends ETV, TDF and TAF as the preferred monotherapy regimens, and the extension of the duration of Peg-IFN therapy beyond week 48 may be beneficial in selected HBeAg-negative CHB patients . The potential side effects of NAs include lactic acidosis for ETV and nephropathy, osteomalacia, lactic acidosis for TDF. CHB patients should be clinically monitored. The most frequently reported side effects for Peg-IFN are flu-like syndrome, myalgia, fatigue, mood disturbances, weight loss, hair loss and local reactions at the site of injection, and these side effects may be partially managed with dose reduction . Currently, the clearance of HBsAg is based primarily on sequential or combined treatment with NA and Peg-IFN.

Can Hepatitis A Be Prevented Or Avoided

The best way to protect yourself against hepatitis A is to get the vaccine. The hepatitis A vaccination is recommended for all children older than age 1. It begins to protect you only 4 weeks after you are vaccinated. A 6- to 12-month booster is required for long-term protection. Ask your doctor if the vaccination is right for you.

You should also wash your hands with soap and warm water before and after cooking, after using the bathroom, and after changing diapers.

Wash fruits and vegetables thoroughly before eating and avoid raw or undercooked meat and fish.

You are at higher risk for hepatitis A if you:

• Live with or have sex with someone who has hepatitis A
• Travel to countries where hepatitis A is common
• Are a man who has sex with other men
• Use illegal drugs
• Have a clotting-factor disorder

How Is Hepatitis B Diagnosed

There are three main ways to diagnose HBV infection. They include:

• Blood tests: Tests of the blood serum shows how your bodys immune system is responding to the virus. A blood test can also tell you if you are immune to HBV.
• Abdominal ultrasound: An ultrasound uses sound waves to show the size and shape of your liver and how well the blood flows through it.
• Liver biopsy: A small sample of your liver tissue is removed though a tiny incision and sent to a lab for analysis.

The blood test that is used to diagnose hepatitis B is not a test that you get routinely during a medical visit. Often, people whove become infected first learn they have hepatitis B when they go to donate blood. Blood donations are routinely scanned for the infection.

The virus can be detected within 30 to 60 days of infection. About 70% of adults with hepatitis B develop symptoms, which tend to appear an average of 90 days after initial exposure to 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

Hbsag Clearance After Na Treatment

There are few large or conclusive studies on the clearance of HBsAg after NA treatment, and some of these studies are single-centre retrospective studies. Kim et al. reported a clearance rate of 1% or less in 110 CHB patients who were treated with ETV/LAM for approximately 1 year. A retrospective study by Yip et al. reported an HBsAg clearance rate of 2.1% after an average follow-up of 4.8 years in 20,263 CHB patients treated with ETV/TDF for longer than 6 months. Wong et al. retrospectively evaluated 1072 CHB patients on antiviral therapy for approximately 6 years and found an HBsAg clearance rate of 4.58%. This study found no significant difference in the clearance rate between HBeAg-positive and HBeAg-negative patients, but the rate in patients with cirrhosis was significantly lower than patients without cirrhosis . These results suggested that the clearance rate of non-cirrhosis patients was higher after NA treatment, which is not consistent with the results of patients who experienced spontaneous clearance. Compared to patients with normal baseline ALT, patients with higher ALT levels had significantly higher rates of achieving HBsAg clearance. In general, the clearance rate may increase with the extension of treatment in CHB patients, but the overall rate with currently available NA treatment is low. The HBsAg clearance rates were 1.45.1% after an average follow-up of 27 years after NA treatment .

Whats The Prognosis For Hepatitis B

Your doctor will know youâve recovered when you no longer have symptoms and blood tests show:

• Your liver is working normally.
• You have hepatitis B surface antibody.

But some people don’t get rid of the infection. If you have it for more than 6 months, youâre whatâs called a carrier, even if you donât have symptoms. This means you can give the disease to someone else through:

• Unprotected sex

How Hepatitis B Is Spread

The hepatitis B virus is found in the blood and bodily fluids, such as semen and vaginal fluids, of an infected person.

It can be spread:

• from a mother to her newborn baby, particularly in countries where the infection is common
• within families in countries where the infection is common
• by having sex with an infected person without using a condom
• by having a tattoo, body piercing, or medical or dental treatment in an unhygienic environment with unsterilised equipment

Hepatitis B is not spread by kissing, holding hands, hugging, coughing, sneezing or sharing crockery and utensils.

Durability And Related Factors After Hbsag Clearance

When patients with HBeAg-positive CHB achieve a satisfactory antiviral treatment endpoint , the clinical recurrence is 2040%, and the virological recurrence can be as high as 8090% after drug withdrawal . Because the safety of drug withdrawal is uncertain, HBsAg clearance is recommended as the ideal treatment endpoint for CHB patients. The accessibility and rate of HBsAg clearance was mentioned above, but the durability of HBsAg clearance after treatment cessation remains controversial.

HBeAg status should also receive attention in the pursuit of HBsAg clearance. The clearance of HBsAg in most patients is based on HBV DNA suppression and HBeAg seroconversion, but a few patients exhibit different HBsAg response patterns, such as HBsAg clearance without HBeAg seroconversion. Only HBsAg clearance based on HBV DNA suppression and HBeAg seroconversion is safe for drug withdrawal .

Chronic Suppression Without Sustained Cure

Current antiviral therapies are aimed towards inhibition of viral replication. Sustained viral suppression is associated with improved outcomes and it has been shown that elevated HBV DNA level is a strong predictor of increased risk of cirrhosis and HCC in CHB. None of the current therapies lead to HBsAg loss or seroconversion in the majority of patients. In addition, current antiviral therapies do not target defective immune response and persistence of covalently closed circular DNA in the infected hepatocytes. Thus, the goal of current treatment is to achieve long-term virologic control since elimination or âcureâ is not possible.

Why Should People Take Antiviral Medications For Hepatitis C

The purpose of taking antiviral medications for hepatitis C is to:

• remove all the hepatitis C virus from your body permanently
• stop or slow down the damage to your liver
• reduce the risk of developing cirrhosis
• reduce the risk of developing liver cancer
• reduce the risk of liver failure and the need for a liver transplant

Hepatitis B And Pregnancy

If youâre pregnant, you might pass the virus to your baby at birth. Itâs less likely to happen during your pregnancy.

If your baby gets the virus and isnât treated, they could have long-term liver problems. All newborns with infected mothers should get hepatitis B immune globulin and the vaccine for hepatitis at birth and during their first year of life.

Can A Transplant Cure Hepatitis C

If you develop chronic hepatitis C and it leads to liver cancer or liver failure, you may need a liver transplant. Hepatitis C is one of the most common reasons for a liver transplant.

A liver transplant removes a damaged liver and replaces it with a healthy one. However, theres a high likelihood that the hepatitis C virus will be transmitted to the new liver in time.

The virus lives in your bloodstream, not just your liver. Removing your liver wont cure the disease.

If you have active hepatitis C, continued damage to your new liver is very likely, especially if hepatitis C remains untreated.

We Can Eliminate Viral Hepatitis Around The World

The tools required to eliminate viral hepatitis are both affordable and available. A timely hepatitis B vaccination of newborns, plus vaccination during school years and the adequate diagnosis and treatment of mothers living with chronic hepatitis B during pregnancy can reduce mother-to-child transmission of the infection more than 95% of the time and break the cycle of transmission across generations. Available drugs can cure more than 90% of people with chronic hepatitis C infection, preventing liver cancer and liver failure.

COVID-19 has triggered one of the worst crises of our times. If we dont act swiftly, its impact will also include millions of new hepatitis B infections in children for years to come.

The pandemic is adding to the severity of the situation as healthcare services, vaccination, screening and treatments have in many areas been disrupted, delayed or stopped altogether. Because of COVID-19’s disruptions to hepatitis B vaccination programmes, there will be millions of new chronic hepatitis B infections among children born between 2020 and 2030. But by acting collectively we can mobilize stakeholders and change the course of history.
