Are There Any Side Effects
Yes, these antiviral drugs and medications are of strong dosages, and there can be side effects that can be short term to long term. Consult with your doctor about your medical conditions and take care of the symptoms that can arise as a result of using these medications. There can be some interferon shots given to young people who do not want long-term treatments, and those side effects can include depression and difficulty in breathing.
What Is Involved In A Liver Transplant
A liver transplant is considered necessary when the liver is damaged and cannot function or in some cases of liver cancer. Your liver is very important. It is responsible for many functions related to making sure that your body stays healthy and is able to digest foods.
You may be eligible for a transplant if you have chronic hepatitis B infection or some of the diseases that may result from it, including liver cancer and cirrhosis. You will have to complete testing and be evaluated before being approved for a transplant. It is likely that you will be placed on a waiting list while an appropriate organ is found.
Donated livers come from two types of donors: living and deceased. Because the liver can regenerate, it is possible to use part of a liver for transplant. The remaining sections in both the donor and the receiver will grow into livers of adequate size.
People who get liver transplants must take anti-rejection drugs for the rest of their lives. These drugs make you more susceptible to infection. However, liver transplants have become more successful over time and continue to improve.
What Is My Risk
Your risk depends of several factors: destination, length of stay, what you do when you are travelling and whether you have direct contact with blood or other body fluids. In certain destinations, your risk may be higher, as some areas have higher numbers of people with chronic hepatitis B in the general population.
The risk increases with certain activities, such as unprotected sex, sharing needles, tattooing and acupuncture.
Aid and health care workers and anyone who receives medical or dental care with unsterilized or contaminated equipment in a country where hepatitis B occurs are also at greater risk.

What Causes Hepatitis B
The hepatitis B virus causes hepatitis B. The hepatitis B virus spreads through contact with an infected persons blood, semen, or other body fluids. Contact can occur by
- being born to a mother with hepatitis B
- having unprotected sex with an infected person
- sharing drug needles or other drug materials with an infected person
- getting an accidental stick with a needle that was used on an infected person
- being tattooed or pierced with tools that were used on an infected person and werent properly sterilized, or cleaned in a way that destroys all viruses and other microbes
- having contact with the blood or open sores of an infected person
- using an infected persons razor, toothbrush, or nail clippers
You cant get hepatitis B from
- being coughed on or sneezed on by an infected person
- drinking unclean water or untreated water that has not been boiled
- eating food that is unclean or has not been properly cooked
- 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
Mothers who have hepatitis B can safely breastfeed their babies. If a baby receives hepatitis B immune globulin and starts receiving the hepatitis B vaccine to prevent hepatitis B infection shortly after birth, hepatitis B is unlikely to spread from mother to child through breastfeeding.15
What Are Clinical Trials For Hepatitis B
Clinical trialsand other types of clinical studiesare part of medical research and involve people like you. When you volunteer to take part in a clinical study, you help doctors and researchers learn more about disease and improve health care for people in the future.
Researchers are studying many aspects of hepatitis B, such as
- progression of hepatitis B and long-term outcomes
- new treatments for hepatitis B
- prevention of reactivated or worsening hepatitis B in people receiving cancer treatment

Causes Of Hepatitis B
Hepatitis B is spread through contact with blood that contains the hepatitis B virus. If infected blood or body fluids enter another persons bloodstream, that person may become infected.
The time from exposure to the hepatitis B virus to the appearance of the illness is 45 to 180 days.
Risky activities that can cause infection include:
- Sharing unsterile or unclean equipment for injecting drugs.
- Piercing the skin with equipment that is not properly cleaned, disinfected and sterilised.
- Sharing razor blades or toothbrushes.
- Coming into contact with infected blood through open cuts or the mucous membranes of another person.
- Having unprotected sex , especially if there is blood present.
Mothers who have hepatitis B can pass the virus to their babies or children at the time of birth or after birth. If the newborn baby is quickly immunised with 2 vaccines, they can be protected from getting hepatitis B.
All blood and blood products produced for medical purposes in Australia are carefully screened for hepatitis B and other blood-borne viruses. The risk of getting infected with hepatitis B from a blood transfusion is extremely low .

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
What Is The Treatment
Hepatitis B affects the liver. However, for many individuals, the virus does not show any symptoms, and many people would be unaware of the fact that they have the virus. There are two stages of the virus The acute stage and the chronic stage. In the acute stage, the virus has been diagnosed before, and the doctor focuses on avoiding its spread and the damage to the liver. In many cases, you might not need any treatment as the virus has a tendency to dissolve on its own. Often the doctor might suggest changes to your dietary pattern and intake of fluids. Also, you have to make some changes to your lifestyle. For safer results, once you have been diagnosed with the virus you might have to take the Hepatitis B immunoglobulin shot along with the hepatitis B vaccine shot. In the chronic cases, your doctors primary focus would be to curtail the spread of the virus and to prevent the further damages to your liver. Antiviral medications might be given to achieve this. However hepatitis B medicines may not be suitable for everyone, and there could be some side effects when undergoing the treatment.

Barriers To Eliminating Hbv
Persistence of cccDNA and its ability to self-replenish and the lack of direct effects of current therapies on cccDNA account for the difficulty in eliminating cccDNA. There are additional barriers to eliminating HBV. HBV DNA can be integrated into the host genome. Although integrated HBV DNA is often rearranged and/or partially deleted and there is no evidence that it supports the full cycle of HBV replication, recent studies suggest that integrated HBV DNA can be sufficiently intact to support translation of viral proteins, e.g., HBsAg. Elimination of integrated HBV DNA will likely require the removal of hepatocytes that harbor these DNA. Control of infections generally requires elimination of the infectious organisms coupled with activation of specific immune responses. Whereas patients who recover from acute HBV infection display rigorous immune responses to multiple HBV epitopes, patients with chronic HBV infection manifest weak immune responses to very few HBV epitopes.
What Other Problems Can Hepatitis B Cause
In rare cases, acute hepatitis B can cause liver failure.
Chronic hepatitis B can develop into a serious disease that causes long-term health problems such as cirrhosis , liver cancer, and liver failure.
If you have ever had hepatitis B, the virus may become active again, or reactivated, later in life. This could start to damage the liver and cause symptoms.

What Are The Risk Factors For Hepatitis B And C
Hepatitis B: Although most commonly acquired early in life, adults can also contract it. Hepatitis B is largely transmitted through bodily fluids. It can be passed at birth from a hepatitis B-infected mother or through exposure in early childhood to body fluids, blood or contaminated medical instruments. Hepatitis B can also be transmitted through intranasal and injection drug use as well as infected tools used during tattooing and body piercing.
Hepatitis C: The key risk factors are also intranasal and injection drug use, tattoos and body piercings, high-risk sexual contact, blood transfusions before 1992 and organ transplantation.
Another key risk factor for hepatitis C is being born from 1945 to 1965, during the baby-boom years. Eighty percent of all people who currently have hepatitis C in the United States were born in that timeframe.
Although the reasons that baby boomers are more likely to have hepatitis C than others arent entirely understood, its believed that most were infected in the 1970s and 1980s, when rates of hepatitis C were at their peak.
The Centers for Disease Control and Prevention and the U.S. Preventive Services Task Force recommend that all U.S. adults born from 1945 to 1965 undergo a one-time screening test for hepatitis C. Connecticut is one of several states that has written this recommendation into law. In Connecticut ,the law requires that primary care clinicians screen all adults born within those years.
The Hepatitis B Vaccine
The hepatitis B vaccine is one of the most effective ways to prevent hepatitis B. Its usually divided into three doses, which are given over the course of six months. In many countries, infants receive their first dose of the vaccine at birth.
The Centers for Disease Control recommends that all children under the age of 19 be vaccinated if they havent already received the vaccination. Adults can also get the hepatitis B vaccine, and its generally recommended if you have an increased risk of infection due to:
- traveling to or living in a region where hepatitis B is common
- being sexually active with more than one partner
- working in a medical setting
- using intravenous drugs
If youve been exposed to the hepatitis B virus and havent been vaccinated, try to see a doctor right away. They can administer the first dose of the vaccine, though youll need to follow up to receive the remaining doses over the next few months.
They can also prescribe a medication called

Efficacy And Safety Of Available Treatments
Currently, two types of treatment, IFNs and NAs, are approved for chronic HBV infection. The virologic responses to these therapies are summarized in Table ., , Pegylated IFNs have a more convenient dosing schedule and improved efficacy. Among the NAs, entecavir , TDF, and tenofovir alafenamide are preferred because of their potent antiviral activity and high barrier to antiviral resistance. A 1-year course of pegylated IFN results in higher rates of HBeAg seroconversion and HBsAg loss than the same duration of ETV, TDF, or TAF therapy in patients who are HBeAg-positive despite lower rates of undetectable HBV DNA . Similarly, in patients who are HBeAg-negative, a 1-year course of pegylated IFN results in a higher rate of HBsAg loss than the same duration of ETV, TDF, or TAF therapy despite a lower rate of undetectable HBV DNA . Response to IFN is more durable, and rates of HBeAg and HBsAg loss continue to increase after cessation of treatment, whereas viral relapse is universal when NA is discontinued after 1 year of therapy.

What Are The Post
The post treatment guidelines are very much mandatory when undergoing the medications. You need to make lots of changes to your lifestyle and in most cases your eating habits. Technically your care for your liver should double, and you might not want to indulge in any activity that can hamper your liver again. You have to ultimately curb your smoking and drinking activities and refrain from using drugs. Also, the medications have to be taken religiously and should never be skipped.

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.
Can Hepatitis B Be Controlled By Eating Right And Exercising
It is important that people with liver disease follow a healthy, nutritious diet as outlined by Health Canada in Eating Well with Canadas Food Guide.
Alcohol can also damage the liver so it is best that people with hepatitis B do not drink. Following a healthy lifestyle may also prevent fatty liver disease, another liver disease highly prevalent in Canada.
However, hepatitis B cannot be controlled by healthy eating and exercise alone. Hepatitis B can only be controlled by currently available treatment as prescribed by your doctor. Your doctor will need to do regular blood tests to know how much of the active virus is in your blood . The viral load test is used to monitor and manage hepatitis B patients. Viral load can tell your doctor if you need treatment for hepatitis B and how well you are responding to treatment.

How Do I Treat My Hepatitis B
Not every patient with chronic hepatitis B needs to be on medication. Although there is no cure for hepatitis B, there are effective treatments that can reduce the risk of liver disease. However, if your ALT level is elevated , antiviral medication may be appropriate. There are currently 7 FDA-approved drugs to treat chronic HBV infection . Talk to your doctor about whether you are good candidate for drug therapy and make sure you discuss treatment rationale, options, side effects, and risks associated with each treatment.
Additionally, if you are chronically infected with hepatitis B and are starting cancer chemotherapy, you should be on HBV treatment to protect against potential flare-up of the hepatitis B infection and risk of liver failure.
