| Description |
Autoimmune urticaria occurs when the immune system attacks the normal tissues of the body, resulting in hives. The condition becomes chronic when the lesions persists longer than 6 weeks. Chronic autoimmune urticaria has been found to be associated with autoimmune thyroid disease.
Urticaria can also be caused by allergic reaction to plants like poison ivy, dyes found in clothing, and cosmetics. An allergic reaction is not an autoimmune disease because there is no involvement by the adaptive immune system and auto-antibodies that attack your own cells are not involved. There are antibodies (IgE antibodies), but they target the invading molecules (e.g., poison ivy), not the cells in the skin. In autoimmune urticaria, the antibodies created are attacking the skin itself, not an invading molecule.
Evidence of autoimmunity: Antibody
