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.
In autoimmune hepatitis, the body's own immune system destroys the cells of the liver. It is a chronic inflammatory liver disease with no known cause.It is associated with a disorder called hypergammaglobulinemia. Hypergammaglobulinemia is a disorder where there are too many circulating protein antibodies in the blood.utoimmune hepatitis may resolve without treatment in some people, but, for the majority, it is chronic and can lead to cirrhosis and liver failure. Autoimmune hepatitis may be classified as type 1 or type 2. Type 1 (classic) is the most common form. It may occur at any age but usually affects young women more than men.
