Hepatitis B Virus Symptoms And Treatment

How Do You Test For Hepatitis B

Hepatitis B: Treatment and care for a chronic condition

A simple blood test carried out by a healthcare professional will show whether you have the virus. You may also be given extra tests to see if your liver is damaged.

If youve got hepatitis B you should be tested for other STIs. Its important that you tell your recent sexual partner/s so they can also get tested and treated. Many people who have hepatitis B dont notice anything wrong, and by telling them you can help to stop the virus being passed on. This can also stop you from getting the infection again.

Symptoms Of Hbv Infection

Hepatitis B has both acute and chronic phases. Acute illness manifests after an incubation period of one to several months. In most individuals, the acute phase is subclinical, with few or no apparent symptoms of illness. A minority of persons, however, develop indications of icteric hepatitis, with a prodromal syndrome characterized by anorexia, nausea, fatigue, and skin rash. Symptoms of liver disease emerge as the condition progresses and include dark urine, pale stools, jaundice with icterus , and pain in the abdomen. Acute symptoms last anywhere from one to four months. Rarely, acute infection leads to fulminant liver failure, with widespread necrosis of the liver and encephalopathy resulting in confusion or coma.

In some instances, following acute infection, HBV remains in the body, leading to chronic infection. Whether chronic infection will develop is determined primarily by the age at which a person becomes infected with HBV. Risk for chronic infection is highest among individuals who are infected perinatally and lowest for individuals who are infected in adulthood.

How To Prevent Hepatitis B The Silent Killer Among Children

The virus causes one lakh deaths per year

Infants more susceptible to this virus

40 million Indians are chronically infected with Hepatitis B

Very frequently, infection is acquired in childhood

Around 1 million children born every year are at risk of developing chronic HBV infection during their life time.

Hepatitis B is a disease caused specifically by hepatitis B virus. The virus infects the liver and may result in inflammation of the liver cells . This results in liver dysfunction. The spectrum of the disease ranges widely from asymptomatic disease or mild jaundice to chronic infection causing liver failure, permanent liver damage or liver cancer says Dr Parijat Ram Tripathy, MBBS, MD , PDCC & DM , Consultant Pediatric Gastroenterologist at Ankura Hospital for Women & children

How common is Hepatitis B?

Hepatitis B is a disease of public health importance due to its high prevalence. In India the prevalence rate is 2-4% in nontribal area and 10-15% or more in tribal areas.

How does the disease spread?

· Perinatal transmission: From mother to her baby at the time of delivery. The infection rate among infants born to HBeAg positive mothers is as high as 90 percent.

· Blood transfusion: The risk of transfusion has significantly reduced after strict testing of donated blood. Children requiring multiple transfusions, such as those with haemophilia and Thalassemia, are at increased risk of contracting HBV infection.

Hepatitis B Causes And Risk Factors

Itâs caused by the hepatitis B virus, and it can spread from person to person in certain ways. You can spread the hepatitis B virus even if you donât feel sick.

The most common ways to get hepatitis B include:

  • Sex. You can get it if you have unprotected sex with someone who has it and your partnerâs blood, saliva, semen, or vaginal secretions enter your body.
  • Sharing needles. The virus spreads easily via needles and syringes contaminated with infected blood.
  • Accidental needle sticks.Health care workers and anyone else who comes in contact with human blood can get it this way.
  • Mother to child.Pregnant women with hepatitis B can pass it to their babies during childbirth. But thereâs a vaccine to prevent newborns from becoming infected.

Hepatitis B doesnât spread through kissing, food or water, shared utensils, coughing or sneezing, or through touch.

Who’s Most At Risk Of Hepatitis B

Hepatitis

People at highest risk of hepatitis B include:

  • people born or brought up in a country where the infection is common
  • babies born to mothers infected with hepatitis B
  • people who have ever injected drugs
  • anyone who has had unprotected sex, including anal or oral sex particularly people who’ve had multiple sexual partners, people who’ve had sex with someone in or from a high-risk area, men who have sex with men, and commercial sex workers
  • close contacts, such as family members, of someone with long-term hepatitis B infection

The risk of getting hepatitis B for travellers going to places where the infection is common is generally considered to be low if the activities mentioned above are avoided.

Your GP can arrange for you to have a blood test to check for hepatitis B and have the hepatitis B vaccination if you’re at a high risk.

Abnormalities In Heme Metabolism And Excretion

One way to understand jaundice pathophysiology is to organize it into disorders that cause increased bilirubin production or decreased bilirubin excretion .

Prehepatic pathophysiology

Prehepatic jaundice is attributed to a pathological increase in bilirubin production. The pathophysiology is quite simple an increased rate of erythrocyte hemolysis increased bilirubin production increased deposition of bilirubin in mucosal tissue appearance of yellow hue.

Hepatic pathophysiology

Hepatic jaundice is due to significant damage to liver function hepatic cell death and necrosis occur impaired bilirubin transport across hepatocytes. Bilirubin transport across may be impaired at any point between hepatocellular uptake of unconjugated bilirubin and hepatocellular transport of conjugated bilirubin into the gallbladder. In addition, subsequent cellular due to inflammation causes mechanical obstruction of intrahepatic biliary tract. Most commonly, interferences in all three major steps of bilirubin metabolism uptake, conjugation, and excretion usually occur in hepatocellular jaundice. Thus, an abnormal rise in both unconjugated and conjugated bilirubin will be present. Because excretion is usually impaired to the greatest extent, conjugated hyperbilirubinemia predominates.

Posthepatic pathophysiology

PresentPresent

Laboratory findings depend on the cause of jaundice:

What Should You Know About Pregnancy And Hepatitis B

A pregnant woman who has hepatitis B can pass the infection to her baby at delivery. This is true for both vaginal and cesarean deliveries.

You should ask your healthcare provider to test you for hepatitis B when you find out you are pregnant. However, while it is important for you and your healthcare provider to know if you do have hepatitis B, the condition should not affect the way that your pregnancy progresses.

If you do test positive, your provider may suggest that you contact another healthcare provider, a liver doctor, who is skilled in managing people with hepatitis B infections. You may have a high viral load and may need treatment during the last 3 months of your pregnancy. A viral load is the term for how much of the infection you have inside of you.

You can prevent your infant from getting hepatitis B infection by making sure that your baby gets the hepatitis B vaccine in the hours after they are born along with the hepatitis B immunoglobulin. These two shots are given in two different locations on the baby. They are the first shots needed.

Depending on the type of vaccine used, two or three more doses must be given, usually when the baby is 1 month old and then 6 months old, with the last by the time the baby is 1 year old. It is critical that all newborns get the hepatitis B vaccination, but even more important if you have hepatitis B yourself.

What Is The Treatment For Viral Hepatitis

    Treatment of acute viral hepatitis and chronic viral hepatitis are different. Treatment of acute viral hepatitis involves resting, relieving symptoms, and maintaining an adequate intake of fluids. Treatment of chronic viral hepatitis involves medications to eradicate the virus and taking measures to prevent further liver damage.

    Acute hepatitis

    In patients with acute viral hepatitis, the initial treatment consists of relieving the symptoms of nausea, vomiting, and abdominal pain . Careful attention should be given to medications or compounds, which can have adverse effects in patients with abnormal liver function . Only those medications that are considered necessary should be administered since the impaired liver is not able to eliminate drugs normally, and drugs may accumulate in the blood and reach toxic levels. Moreover, sedatives and “tranquilizers” are avoided because they may accentuate the effects of liver failure on the brain and cause lethargy and coma. The patient must abstain from drinking alcohol since alcohol is toxic to the liver. It occasionally is necessary to provide intravenous fluids to prevent dehydration caused by vomiting. Patients with severe nausea and/or vomiting may need to be hospitalized for treatment and intravenous fluids.

    Chronic hepatitis

    Medications for chronic hepatitis C infection include:

    • oral daclatasvir

    Medications for chronic hepatitis B infection include:

    Fulminant hepatitis

    Is There A Hepatitis B Vaccine

    Hepatitis B and hepatitis D virus- causes, symptoms, diagnosis, treatment, pathology

    There is a vaccine against the hepatitis B virus . It is safe and works well to prevent the disease. A total of 3 doses of the vaccine are given over several months. Hepatitis B vaccine is also produced as a combination product which includes other common childhood vaccinations. This can reduce the number of shots that a child needs at a single visit.

    The following groups should be vaccinated for hepatitis B:

    • All children younger than 19 years, including all newborns – especially those born to mothers who are infected with HBV
    • All health care and public safety workers who may be exposed to blood
    • People who have hemophilia or other blood clotting disorders and receive transfusions of human clotting factors

    What Are The Medications For Hepatitis B

    All of the following medications used to treat chronic hepatitis B are antiviral medications. They reduce the ability of the virus to reproduce in the body and give the liver a chance to heal itself. These drugs are not a cure for hepatitis B, but they do reduce the damage caused by the virus. Although these medications are similar in some ways, they differ in other important ways. Talk to your health care practitioner about the best medication for you.

    Pegylated interferon alfa-2b

    Pegylated interferon is used alone or in combination with other medications.

    Nucleoside/nucleotide analogues

    Nucleoside/nucleotide analogues are compounds that mimic normal building blocks for DNA. When the virus tries to use the analogues, it is unable to make new viral particles. Examples of these agents include adefovir , entecavir , lamivudine , Telbivudine and tenofovir .

    Approaches By Virus Life Cycle Stage

    consist of a and sometimes a few stored in a capsule made of , and sometimes covered with a layer . Viruses cannot reproduce on their own and instead propagate by subjugating a host cell to produce copies of themselves, thus producing the next generation.

    Researchers working on such “” strategies for developing antivirals have tried to attack viruses at every stage of their life cycles. Some species of mushrooms have been found to contain multiple antiviral chemicals with similar synergistic effects.Compounds isolated from fruiting bodies and filtrates of various mushrooms have broad-spectrum antiviral activities, but successful production and availability of such compounds as frontline antiviral is a long way away. Viral life cycles vary in their precise details depending on the type of virus, but they all share a general pattern:

  • Attachment to a host cell.
  • Release of viral genes and possibly enzymes into the host cell.
  • Replication of viral components using host-cell machinery.
  • Assembly of viral components into complete viral particles.
  • Release of viral particles to infect new host cells.
  • Before cell entry

    This stage of viral replication can be inhibited in two ways:

  • Using agents which mimic the virus-associated protein and bind to the cellular receptors. This may include VAP , natural of the receptor and anti-receptor antibodies.
  • Uncoating inhibitor

    Inhibitors of uncoating have also been investigated.

    Acute Hepatitis B Infection

    There is no specific treatment for acute hepatitis B, and most people recover within one to two months. Usually, you can manage symptoms at home with painkillers if necessary. Your healthcare professional should advise you to have regular blood tests and physical check-ups. Most people make a full recovery from acute hepatitis B.

    How Do Doctors Treat The Complications Of Hepatitis B

    Hepatitis B virus information

    If chronic hepatitis B leads to cirrhosis, you should see a doctor who specializes in liver diseases. Doctors can treat the health problems related to cirrhosis with medicines, minor medical procedures, and surgery. If you have cirrhosis, you have an increased chance of liver cancer. Your doctor may order blood tests and an ultrasound or another type of imaging test to check for liver cancer.

    If chronic hepatitis B leads to liver failure or liver cancer, you may need a liver transplant.

    Can Hepatitis B Be Prevented

    The hepatitis B vaccine is one of the best ways to control the disease. It is safe, effective and widely available. More than one billion doses of the vaccine have been administered globally since 1982. The World Health Organization says the vaccine is 98-100% effective in guarding against the virus. Newborns should be vaccinated.

    The disease has also been more widely prevented thanks to:

    • Widespread global adoption of safe blood-handling practices. WHO says 97% of the blood donated around the world is now screened for HBV and other diseases.
    • Safer blood injection practices, using clean needles.
    • Safe-sex practices.

    You can help prevent hepatitis B infections by:

    • Practicing safe sex .
    • Never sharing personal care items like toothbrushes or razors.
    • Getting tattoos or piercings only at shops that employ safe hygiene practices.
    • Not sharing needles to use drugs.
    • Asking your healthcare provider for blood tests to determine if you have HBV or if you are immune.

    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

    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

    Are There Home Remedies For Hepatitis B

    Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis D, Hepatitis E – Features, Symptoms, and Treatment

    The goals of self-care are to relieve symptoms and prevent worsening of the disease.

    • Drink plenty of fluids to prevent dehydration. Broth, sports drinks, gelatin, frozen ice treats , and fruit juices are preferred because they also provide calories.
    • Ask your physician before taking any medications, even those that are over-the-counter. Some medications depend on the liver, and liver damage may impair the body’s ability to metabolize these drugs. If you are on prescription medications, check with your physician to see if the doses should be adjusted or if the medication should be temporarily discontinued.
    • Avoid drinking alcohol until your healthcare practitioner allows it. Individuals with chronic HBV should avoid alcohol for the rest of their lives.
    • Try to eat a diet that provides adequate nutrition. Take it easy. It may take some time for your energy level to return to normal.
    • Avoid prolonged, vigorous exercise until symptoms start to improve.
    • Avoid any activity that may spread the infection to other people .

    Viral Hepatitis Definition And Overview

    Hepatitis means inflammation of the liver. Many illnesses and conditions can cause inflammation of the liver, for example, drugs, alcohol, chemicals, and autoimmune diseases. Many viruses, for example, the virus causing mononucleosis and the cytomegalovirus, can inflame the liver. Most viruses, however, do not attack primarily the liver the liver is just one of several organs that the viruses affect. When most doctors speak of viral hepatitis, they are using the definition that means hepatitis caused by a few specific viruses that primarily attack the liver and are responsible for about half of all human hepatitis. There are several hepatitis viruses they have been named types A, B, C, D, E, F , and G. As our knowledge of hepatitis viruses grows, it is likely that this alphabetical list will become longer. The most common hepatitis viruses are types A, B, and C. Reference to the hepatitis viruses often occurs in an abbreviated form The focus of this article is on these viruses that cause the majority of human viral hepatitis.

    Hepatitis viruses replicate primarily in the liver cells. This can cause the liver to be unable to perform its functions. The following is a list of major functions of the liver:
