Autoimmune hepatitis

Definition

Autoimmune hepatitis involves inflammation of the liver caused by rogue immune cells that mistake the liver's normal cells for a foreign tissue or pathogen (disease-causing agent).

Causes, incidence, and risk factors

Autoimmune hepatitis sometimes occurs in relatives of people with autoimmune diseases, suggesting a genetic cause.

This disease is most common in young girls and women.

Treatment

Prednisone or other corticosteroids help reduce the inflammation. Azathioprine or mercaptopurine are drugs used to treat other autoimmune disorders, and they have benefitted patients with autoimmune hepatitis as well.

Modify your activity level according to your symptoms.

Expectations (prognosis)

The outcome varies. Corticosteroid therapy may slow the disease progression. However, autoimmune hepatitis may progress to cirrhosis and require liver transplant.

Complications

Calling your health care provider

Call your health care provider if you notice symptoms of autoimmune hepatitis.
