What Is The Definition Of Hepatitis

How Common Is Autoimmune Hepatitis

What is hepatitis?

Researchers arent sure how common autoimmune hepatitis is in the United States. Studies conducted in northern European countries have found that between 10 and 24 of every 100,000 people in that region have autoimmune hepatitis. Researchers have found that the disease is more common among Alaska Natives, affecting about 43 of every 100,000 people.1

Screening For Viral Hepatitis

The purpose of screening for viral hepatitis is to identify people infected with the disease as early as possible, even before symptoms and transaminase elevations may be present. This allows for early treatment, which can both prevent disease progression and decrease the likelihood of transmission to others.

Hepatitis A

Hepatitis A causes an acute illness that does not progress to chronic liver disease. Therefore, the role of screening is to assess immune status in people who are at high risk of contracting the virus, as well as in people with known liver disease for whom hepatitis A infection could lead to liver failure. People in these groups who are not already immune can receive the hepatitis A vaccine.

Those at high risk and in need of screening include:

  • People with poor sanitary habits such as not washing hands after using the restroom or changing diapers
  • People who do not have access to clean water
  • People in close contact with someone who has hepatitis A
  • People who use illicit drugs
  • People with liver disease
  • People traveling to an area with endemic hepatitis A

The presence of anti-hepatitis A IgG in the blood indicates past infection with the virus or prior vaccination.

Hepatitis B

The CDC, WHO, USPSTF, and ACOG recommend routine hepatitis B screening for certain high-risk populations. Specifically, these populations include people who are:

Other

Hepatitis A

Hepatitis B and C

Hepatitis D

Hepatitis E

Alcoholic hepatitis

Can Hepatitis Be Prevented

There are different ways to prevent or lower your risk for hepatitis, depending on the type of hepatitis. For example, not drinking too much alcohol can prevent alcoholic hepatitis. There are vaccines to prevent hepatitis A and B. Autoimmune hepatitis cannot be prevented.

Hepatitis C And The Hep C Virus

Hepatitis C is a liver infection that can lead to serious liver damage. Its caused by the hepatitis C virus. About 2.4 million people in the U.S. have the disease. But it causes few symptoms, so most of them don’t know. The virus spreads through an infected persons blood or body fluids.

There are many forms of the hepatitis C virus, or HCV. The most common in the U.S. is type 1. None is more serious than any other, but they respond differently to treatment.

What Are The Treatments For Hepatitis

Chronic hepatitis

Treatment for hepatitis depends on which type you have and whether it is acute or chronic. Acute viral hepatitis often goes away on its own. To feel better, you may just need to rest and get enough fluids. But in some cases, it may be more serious. You might even need treatment in a hospital.

There are different medicines to treat the different chronic types of hepatitis. Possible other treatments may include surgery and other medical procedures. People who have alcoholic hepatitis need to stop drinking. If your chronic hepatitis leads to liver failure or liver cancer, you may need a liver transplant.

What’s The Difference Between An Adenovirus And Coronavirus

Adenoviruses and coronaviruses are both considered by health experts to be “common respiratory viruses.” Each have several different strains, or types of the virus, with some types causing more severe illness than others.

“Coronavirus is a respiratory illness. Adenovirus is a respiratory illness as well,” Alonso said. “It’s transmitted in very much the same way as coronaviruses, but they’re two very distinct viruses. Adenovirus is not associated with these severe respiratory symptoms in immune competent children. The adenovirus has not been associated with a inflammatory condition after the infection, the way coronavirus has been associated with the MIS-C diagnosis. But both can be circulating in the community at the same time and both are transmitted the same way. They’re just two very distinct viruses.”

History And Physical Exam

To diagnose all forms of hepatitis, your doctor will first take your history to determine any risk factors you may have.

During a physical examination, your doctor may press down gently on your abdomen to see if there√Ęs pain or tenderness. Your doctor may also check for any swelling of the liver and any yellow discoloration in your eyes or skin.

Hepatitis B And Your Liver

The liver is such an important organ that we can survive only one or two days if it completely shuts down – if the liver fails, your body will fail, too. Fortunately, the liver can function even when up to 80% of it is diseased or removed. This is because it has the amazing ability to regenerate – or create – itself from healthy liver cells that still exist.

If your body were an automobile, your liver would be considered the engine. It does hundreds of vital things to make sure everything runs smoothly:

  • Stores vitamins, sugar and iron to help give your body energy
  • Controls the production and removal of cholesterol
  • Clears your blood of waste products, drugs and other poisonous substances
  • Makes clotting factors to stop excessive bleeding after cuts or injuries
  • Produces immune factors and removes bacteria from the bloodstream to combat infection
  • Releases a substance called “bile” to help digest food and absorb important nutrients

The word hepatitis actually means inflammation of the liver. Thus, hepatitis B refers to inflammation of the liver caused by the hepatitis B virus. With early detection and appropriate follow-up medical care, people living with a chronic hepatitis B infection can expect to enjoy a long and healthy life.

When To See A Healthcare Provider

If you develop any of the symptoms of chronic hepatitis, liver damage, or liver cancer, see your healthcare provider. It takes only a blood test to detect the presence of a hepatitis virus in your body .

A blood test also can determine which hepatitis virus you’re infected with, which will determine what your treatment should be .

Vaccines And Immune Globulin

Vaccines to prevent hepatitis A and hepatitis B are available in the United States. A vaccine for hepatitis E is currently available only in China. No vaccines against hepatitis C or D virus are available. However, vaccination against hepatitis B virus also reduces the risk of infection with hepatitis D virus. Hepatitis vaccines are given by injection into muscle.

Routine vaccination with the hepatitis A vaccine Hepatitis A Vaccine read more and hepatitis B vaccine Hepatitis B Vaccine read more is recommended in the United States for all children and for adults at high risk of getting hepatitis Hepatitis is common throughout the world. Hepatitis can be Acute read more ).

As with most vaccines, protection requires allowing a number of weeks for the vaccine to reach its full effect as the immune system gradually creates antibodies against the particular virus.

If people who have not been vaccinated are exposed to hepatitis A virus, they are given a single dose of hepatitis A vaccine or an injection of standard immune globulin, depending on their age and health. Standard immune globulin contains antibodies obtained from blood collected from a large group of people who have a normal immune system. Immune globulin prevents infection or decreases its severity. However, the amount of protection it provides varies, and the protection is only temporary.

Babies born to mothers with hepatitis B are given hepatitis B immune globulin and hepatitis B vaccine.

Treatment Of Acute Viral Hepatitis

  • Supportive care

For most people with acute viral hepatitis, special treatment is not necessary. However, people with severe acute hepatitis may require hospitalization so that symptoms can be treated. If doctors suspect that fulminant hepatitis is developing, the person is hospitalized so that mental status can be monitored, liver tests can be done, and doctors can determine whether liver transplantation is needed.

After the first several days, appetite usually returns and people do not need to stay in bed. Severe restrictions of diet or activity are unnecessary, and vitamin supplements are not required. Most people can safely return to work after the jaundice clears, even if their liver test results are not quite normal.

People with hepatitis should not drink alcohol until they have fully recovered.

The infected liver may not process drugs normally. So a doctor may need to stop a drug or reduce the dosage of a drug that could accumulate to harmful levels in the body . Thus, people with hepatitis should tell their doctor all the drugs they are taking , so that the dosage of the drug can be adjusted if necessary.

If itching occurs, cholestyramine, taken by mouth, is often effective.

Symptoms Of Acute Viral Hepatitis

Hepatitis B by David Pfeifer

Acute viral hepatitis can cause anything from a minor flu-like illness to fatal liver failure Liver Failure Liver failure is severe deterioration in liver function. Liver failure is caused by a disorder or substance that damages the liver. Most people have jaundice , feel tired… read more . Sometimes there are no symptoms. The severity of symptoms and speed of recovery vary considerably, depending on the particular virus and on the person’s response to the infection. Hepatitis A and C often cause very mild symptoms or none at all and may be unnoticed. Hepatitis B and E are more likely to produce severe symptoms. Infection with both hepatitis B and D may make the symptoms of hepatitis B even more severe.

Symptoms of acute viral hepatitis usually begin suddenly. They include

  • A poor appetite

People with acute viral hepatitis usually recover in 4 to 8 weeks, even without treatment. However, some people infected with hepatitis B or C develop chronic infections.

What Is Viral Hepatitis

Hepatitis means inflammation of the liver. The liver is a vital organ that processes nutrients, filters the blood, and fights infections. When the liver is inflamed or damaged, its function can be affected. Heavy alcohol use, toxins, some medications, and certain medical conditions can cause hepatitis. However, hepatitis is often caused by a virus. In the United States, the most common types of viral hepatitis are hepatitis A, hepatitis B, and hepatitis C.

How Worried Should You Be

The WHO noted that although there has been an increase in adenovirus in Britain, the potential role of those viruses in triggering hepatitis is unclear. WHO said there were fewer than five possible cases in Ireland and three confirmed cases in Spain, in children aged 22 months to 13 years.

The U.N. health agency said that given the jump in cases in the past month and heightened surveillance, it was very likely more cases will be detected.

Still, experts say the risk of severe hepatitis in healthy children remains rare.

“It’s still very unusual, you know,” Welbel said. “So far we’ve seem very, you know, a very small handful of cases, some of those cases were severe and a couple did require liver transplant in the U.S., but so far it’s still what I would call rare.”

Willowbrook State School Experiments

A New York University researcher named Saul Krugman continued this research into the 1950s and 1960s, most infamously with his experiments on mentally disabled children at the Willowbrook State School in New York, a crowded urban facility where hepatitis infections were highly endemic to the student body. Krugman injected students with gamma globulin, a type of antibody. After observing the temporary protection against infection this antibody provided, he then tried injected live hepatitis virus into students. Krugman also controversially took feces from infected students, blended it into milkshakes, and fed it to newly admitted children.

What Causes Hepatitis

There are different types of hepatitis, with different causes:

  • Viral hepatitis is the most common type. It is caused by one of several viruses — hepatitis viruses A, B, C, D, and E. In the United States, A, B, and C are the most common.
  • Alcoholic hepatitis is caused by heavy alcohol use
  • Toxic hepatitis can be caused by certain poisons, chemicals, medicines, or supplements
  • Autoimmune hepatitis is a chronic type in which your body’s immune system attacks your liver. The cause is not known, but genetics and your environment may play a role.

How Is It Spread

Hepatitis A is spread when a person ingests fecal mattereven in microscopic amountsfrom contact with objects, food, or drinks contaminated by feces or stool from an infected person.

Hepatitis B is primarily spread when blood, semen, or certain other body fluids- even in microscopic amounts from a person infected with the hepatitis B virus enters the body of someone who is not infected. The hepatitis B virus can also be transmitted from:

  • Birth to an infected mother
  • Sex with an infected person
  • Sharing equipment that has been contaminated with blood from an infected person, such as needles, syringes, and even medical equipment, such as glucose monitors
  • Sharing personal items such as toothbrushes or razors
  • Poor infection control has resulted in outbreaks in health care facilities

Hepatitis C is spread when blood from a person infected with the Hepatitis C virus even in microscopic amounts enters the body of someone who is not infected. The hepatitis C virus can also be transmitted from:

  • Sharing equipment that has been contaminated with blood from an infected person, such as needles and syringes
  • Receiving a blood transfusion or organ transplant before 1992
  • Poor infection control has resulted in outbreaks in health care facilities
  • Birth to an infected mother

What Is Autoimmune Hepatitis

Autoimmune hepatitis is a chronic disease in which your bodys immune system attacks the liver and causes inflammation and liver damage. Without treatment, autoimmune hepatitis may get worse and lead to complications, such as cirrhosis and liver failure.

Autoimmune hepatitis is an autoimmune disease. Your immune system normally makes large numbers of antibodies and lymphocytes that help fight off infections. The normal immune system does not attack healthy cells in a persons body. In autoimmune diseases, your immune system makes certain types of antibodiescalled autoantibodiesand lymphocytes that attack your bodys own cells and organs.
