Autoimmune Hepatitis Of The Liver

How Is Autoimmune Hepatitis Diagnosed

Autoimmune hepatitis – causes, symptoms, diagnosis, treatment & pathology

Your healthcare provider will look at your health history and give you a physical exam.

Some lab blood tests used to diagnose autoimmune hepatitis include:

  • Liver function tests. These check for inflammation or damage to your liver.
  • Complete blood count or CBC. Looks at the number and types of cells in your blood.
  • Coagulation panel. This test looks at how well the clotting proteins are working.
  • Electrolyte panel. Checks to see if you have an electrolyte imbalance.
  • Autoimmune antibodies. These are used to see if you have autoimmune hepatitis or another liver disease with similar symptoms.
  • Other liver tests. These are done to check for other possible types of liver disease.

You may also have imaging tests such as:

Genetics And Predisposing Factors

Autoimmune hepatitis is thought to result from an environmental trigger in a genetically predisposed individual, leading to loss of tolerance of T lymphocytes with subsequent hepatocyte attack.

It is a polygenic disease and does not follow a Mendelian distribution. Therefore there is no need to screen family members of patients with AIH. There is a strong genetic association with the alleles of the major histocompatibility complex class II. The presence of human leukocyte antigen genes HLA DRB1*03 and HLA DRB1*04 predisposes to AIH type 1 and affect the disease course and response to treatment. Individuals who are positive for HLA DRB1*03 are younger, respond less favorably to corticosteroid therapy, and progress more often to liver failure. On the other hand, the presence of HLA DRB1*04 is associated with higher rates of concomitant autoimmune disorders.

Autoimmune hepatitis can also be associated with autoimmune polyendocrinopathy candidiasis ectodermal dystrophy syndrome, an autosomal recessive disease characterized by hypoparathyroidism, adrenal insufficiency, and chronic mucocutaneous candidiasis. Autoimmune polyendocrinopathy candidiasis ectodermal dystrophy is the only AIH-associated disease that follows a Mendelian pattern of inheritance and genetic counseling should be offered for patients and family members.

Complementary And Alternative Medicines

Many complementary and alternative medicines available suggest they can ease the symptoms of liver disease. As with any other medicine, you should use them with care. Your doctor or a registered dietitian will have full access to your medical history and be able to offer advice on treatments that are specific to you and will not interact with any of your other medications.

Do Medicines Used To Treat Autoimmune Hepatitis Have Side Effects

Medicines for autoimmune hepatitis can cause side effects. Your doctor will monitor any side effects and help you manage them while you take these medicines. Your doctor also may adjust the doses or change the medicines you take. You may need to stop taking corticosteroids or azathioprine if you have severe side effects.

Side effects of corticosteroids may include

  • changes in how you look, which may include weight gain, a fuller face, acne, or more facial hair

Corticosteroids and azathioprine suppress, or decrease the activity of, your immune system, which increases your risk for infections. These medicines can also increase your risk of developing cancers, especially skin cancers.

What Is Autoimmune Hepatitis

Autoimmune Disease Hepatitis Of The Liver

The liver is a large organ that sits up under your ribs on the right side of your belly . It helps filter waste from your body, makes bile to help digest food, and stores sugar that your body uses for energy. Autoimmune hepatitis occurs when your bodys infection-fighting system attacks your liver cells. This causes swelling, inflammation and liver damage.

It is a long-term or chronic inflammatory liver disease.

Autoimmune hepatitis:

  • May occur at any age
  • Affects women more than men
  • Is often linked to other diseases where the body attacks itself

Is Autoimmune Hepatitis Serious

Autoimmune hepatitis AIH is a substantial inflammation of the liver mediated by an autoimmune response against the hepatocytes themselves, which manifests clinically as positive autoantibodies, hyper-IgGemia and gamma-globulinemia, and on liver histology as interface hepatitis. Autoimmune hepatitis is a more serious and complex liver disease, which often leads to cirrhosis and even liver failure if not treated properly. AIH can manifest clinically as a chronic process, and some patients have an acute, fulminant process. some data show that about 30% of patients are already cirrhotic by the time they are found to have AIH, and all patients with AIH About 1-2% of all AIH patients will develop into hepatocellular carcinoma, so it is a more serious and complicated liver disease.

About Autoimmune Liver Disease

Autoimmune liver diseases are typically long-lasting and recurring conditions. This means that you may experience persistent immune system attacks that destroy liver cells. As cells die, scar tissue known as fibrosis forms. Autoimmune diseases tend to progress slowly, and you may have long periods without symptoms. When scarring becomes extreme, liver function weakens and eventually may result in a condition known as cirrhosis. Cirrhosis is also known as liver failure or end-stage liver disease. The only cure for this condition is organ transplantation. While the only cure for severe cirrhosis is transplantation, we can help you manage the symptoms of the disease with medication before or instead of transplantation.

What Is A Possible Complication Of Autoimmune Hepatitis And Cirrhosis

People with autoimmune hepatitis and cirrhosis are at risk of developing liver cancer. A health care provider will monitor the person with a regular ultrasound examination of the liver. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. A specially trained technician performs the procedure in a health care provider’s office, an outpatient center, or a hospital, and a radiologista doctor who specializes in medical imaginginterprets the images anesthesia is not needed. The images can show the liver’s size and the presence of cancerous tumors.

Potential Outcomes Of Immunosuppressant Therapy

The goal of treatment is disease remission. In remission, patients experience the improvement of symptoms, the normalization of abnormal liver chemistries and gamma globulin levels, and the reduction or elimination of inflammatory activity on liver biopsy.

Most patients who embark on a course of immunosuppressant therapy respond well initially. More than 90% of adults started on corticosteroid treatment experience improvements in liver chemistries and gamma globulin levels within 2 weeks.

Remission, if it is to be achieved, typically requires 18-24 months of immunosuppressant therapy. Remission can be achieved in about 65% of patients within 18 months and 80% of patients within 3 years. Once a drug-induced remission is achieved, an attempt should be made to withdraw immunosuppression. However, a sustained remission after total drug withdrawal is seen in 13% of patients at 5 years. Patients who relapse need to restart long-term immunosuppressant therapy in an effort to normalize their biochemical abnormalities and to delay the progression of liver disease. Many such patients are maintained on chronic maintenance therapy with azathioprine.

About 13% of patients experience an incomplete response to treatment, without worsening of their condition. Most incomplete responders need long-term immunosuppression in an attempt to stabilize levels of aspartate transaminase and alanine aminotransferase andby extensionprevent disease progression.


How Is Autoimmune Hepatitis Treated In A Child

Autoimmune hepatitis is a serious, long-lasting disease. Right now, there is no cure for autoimmune hepatitis. Fortunately, most children with autoimmune hepatitis respond well to treatment.

The goal of autoimmune hepatitis treatment is remission. This means symptoms become less severe and liver damage slows or stops. Some children are able to stop taking medicine after two or three years. These children will still need to be watched for a return of autoimmune hepatitis symptoms and other health issues.

Two main types of medicine are used to help control autoimmune hepatitis in children:

  • Corticosteroids . Prednisone helps stop the immune system from attacking the liver. It also reduces liver inflammation. Budesonide is another corticosteroid that is sometimes used it has less side effects, but it is mostly given later on when the disease is under control already.
  • Immunosuppressants. Azathioprine or mercaptopurine are often added to the treatment they work together with prednisone to get the immune system under control. There are other medications to suppress the immune system that can be used if the standard treatment is not working well.

What Are The Causes

There is still no known direct cause for autoimmune hepatitis. note that people who have a family history of autoimmune conditions, or those with other autoimmune diseases, may be more likely to get autoimmune hepatitis.

According to the , some common medicines may cause autoimmune liver injury, including the antibiotics minocycline and nitrofurantoin. However, in these cases, the symptoms typically clear up once the person stops taking the medication.

No matter what triggers the disease, the cause of the symptoms is damage to the liver. The immune system in the body gets wrong signals about normal cells, mistaking them for invading cells. It attacks these cells and damages the liver tissue, leading to symptoms over time.

If a person suspects they may have liver damage, they should see a doctor.

Doctors will ask about:

The goal of treatment is to suppress symptoms and control the disease, as best as possible.

The first treatment many doctors provide is corticosteroids or immune system-suppressing drugs. These medications work to lower activity of the immune system in general, which may help slow the attack on the liver.

Treatment will also include regular blood tests to be sure the body is responding well to the treatment.

Overview and Symptoms

Although a number of autoimmune conditions may involve the liver, the three most common autoimmune liver diseases are autoimmune hepatitis, primary biliary cholangitis and primary sclerosing cholangitis. These conditions may occur individually or as part of overlap syndromes.

What Are The Current Treatment Options

Very mild cases or inactive phases of the disease may not require treatment. However, for more serious cases, treatment to fight acute episodes is important.

For many individuals, lifelong medication use may be required to keep the bodys autoimmune response under control and preserve liver health.

The two main medications used to treat autoimmune hepatitis are:

  • prednisone: a corticosteroid
  • azathioprine: an immunomodulator or steroid-sparing agent

Other medications may be added in severe cases. If medications are no longer effective and liver failure is likely, a liver transplant may be necessary.

If possible, your treatment should be supervised by a hepatologist, which is a physician who specializes in liver health.

What Are The Complications Of Autoimmune Hepatitis In A Child

Autoimmune hepatitis can cause scar tissue to start forming on the damaged liver . This makes it harder for the liver to work properly. Over time, lots of scar tissue can build up in the liver . This can block the blood flowing through the liver and may lead to problems such as bleeding in the esophagus or stomach, or water in the belly . Cirrhosis also can cause the liver to fail signs may be jaundice , bleeding/bruising, or confusion.

When The Liver Is Under Attack

In people with autoimmune hepatitis, immune cells inappropriately mistake the livers normal cells as abnormal and attack them. Over time, this can lead to inflammation, scarring , impaired liver function, and even cirrhosis , which can result in liver failure, and death if not treated. Some people may eventually need a liver transplant. The liver disease specialists at NewYork-Presbyterians Center for Liver Disease and Transplantation are experienced in diagnosing and treating autoimmune hepatitis.

What Causes Autoimmune Hepatitis In Children

It is not known exactly why the immune system begins attacking liver cells in children with autoimmune hepatitis.

Experts are looking at a number of possible causes, including:

  • Genetics. Physical traits passed down from parents
  • Environment. Causes of disease from outside the body, such as toxic substances, certain medicines, or germs
  • Problems with the immune system. For example, in patients with autoimmune hepatitis, it seems that some cells that regulate the immune system are fewer or weaker, while other cells that make the immune system attack are more frequent or more active.
