What is autoimmune hepatitis?

Autoimmune hepatitis is a type of liver inflammation in which the body’s immune cells attack healthy liver cells after mistaking them for disease-causing foreign substances. It affects children and adults at any age. It is often diagnosed in individuals who have been previously diagnosed with a different autoimmune disorder.

The liver assists the digestive system and carries out many other essential functions. These functions include producing bile to help break down food into energy; creating essential substances, such as hormones; cleaning toxins from the blood, including those from medication, alcohol and drugs; and controlling fat storage and cholesterol production and release.

Autoimmune hepatitis is a disease that affects two body systems, the liver, which is part of your gastrointestinal system, and your immune system. While other forms of hepatitis are caused by bacteria or viruses, in autoimmune hepatitis, the immune system itself attacks the liver cells because it cannot distinguish between harmful invaders and healthy liver tissue.

The prognosis for autoimmune hepatitis varies. In many people, corticosteroid therapy is effective in slowing or even stopping the disease’s progress. In other cases, autoimmune hepatitis may develop into cirrhosis, in which liver cells are replaced with scar tissue. Cirrhosis causes permanent liver dysfunction and may require a liver transplant. Patients with chronic liver inflammation are at increased risk for developing liver cancer.

All symptoms of autoimmune hepatitis require prompt attention, but some are more urgent than others. Seek immediate medical care (call 911) for serious symptoms associated with complications, such as confusion, agitation, severe abdominal swelling, severe abdominal pain, sweating, and severe difficulty breathing.

Seek prompt medical care if you experience abdominal swelling, dark urine, fatigue, malaise, itchy skin, loss of appetite, nausea with or without vomiting, or pale or clay-colored stools. Also seek prompt medical care if you are being treated for autoimmune hepatitis, but your symptoms recur or are persistent.

What causes autoimmune hepatitis?

In autoimmune diseases, the immune system itself initiates inflammation because it cannot tell the difference between harmful invaders and healthy body tissue. Thus, in the case of autoimmune hepatitis, the body’s immune cells attack healthy cells in the liver after mistaking them for disease-causing foreign substances.

Autoimmune hepatitis is sometimes classified as type 1 or typ... Read more about autoimmune hepatitiscauses


How is autoimmune hepatitis treated?

The treatment of autoimmune hepatitis begins with seeking medical care from your health care provider. If you have autoimmune hepatitis, your doctor will most likely start you on a course of corticosteroid therapy and, if needed, other immunosuppressants (medications that suppress the activity of the immune system). Following your treatment plan can slow or sometimes even stop the progression o... Read more about autoimmune hepatitistreatments
