To confirm a diagnosis of celiac disease, a biopsy of the small intestine is examined to detect damage to the intestinal villi. However, given the invasive nature and cost of a biopsy, antibody tests are often used to identify those individuals with high probability of having celiac disease.
Autoimmune hepatitis is a disease in which the body's immune system attacks liver cells. This immune response causes inflammation of the liver, also called hepatitis. Researchers think a genetic factor may make some people more susceptible to autoimmune diseases.
Viruses cause most types of hepatitis. Autoimmune hepatitis (AIH) is one exception. This type of liver disease occurs when your immune system attacks your liver cells. AIH is a chronic condition and can result in cirrhosis (scarring) of the liver and (ultimately) liver failure.utoimmune hepatitis (AIH) is one exception.
