What are the causes for Autoimmune Hepatitis?

This form of hepatitis is an autoimmune disease. The body's immune system cannot tell the difference between healthy body tissue and harmful, outside substances. The result is an immune response that destroys normal body tissues.

Liver inflammation, or hepatitis, may occur along with other autoimmune diseases. These include:

• Graves disease
• Inflammatory bowel disease
• Rheumatoid arthritis
• Scleroderma
• Sjögren syndrome
• Systemic lupus erythematosus
• Thyroiditis
• Type 1 diabetes
• Ulcerative colitis

Autoimmune hepatitis may occur in family members of people with autoimmune diseases. There may be a genetic cause.

This disease is most common in young girls and women.

What are the symptoms for Autoimmune Hepatitis?

Symptoms may include:

• Fatigue
• General discomfort, uneasiness, or ill feeling (malaise)
• Itching
• Loss of appetite
• Nausea or vomiting
• Joint pain
• Pale or clay-colored stools
• Dark urine
• Abdominal distention

Absence of menstruation (amenorrhea) may also be a symptom.

What are the current treatments for Autoimmune Hepatitis?

You may need prednisone or other corticosteroid medicines to help reduce the inflammation. Azathioprine and 6-mercaptopurine are drugs used to treat other autoimmune disorders. They have been shown to help people with autoimmune hepatitis, as well.

Some people may need a liver transplant.

What is the outlook (prognosis) for Autoimmune Hepatitis?

The outcome varies. Corticosteroid medicines may slow the progress of the disease. However, autoimmune hepatitis may advance to cirrhosis. This would require a liver transplant.

What are the possible complications for Autoimmune Hepatitis?

Complications may include:

• Cirrhosis
• Side effects from steroids and other medicines
• Hepatocellular carcinoma
• Liver failure

When should I contact a medical professional for Autoimmune Hepatitis?
