Autoimmune urticaria is characterized by the presence of autoantibodies, which are antibodies that the immune system mistakenly produces against the body's own cells.In the case of autoimmune urticaria, these autoantibodies primarily target the high-affinity IgE receptor (FcεRI) on mast cells and basophils, or less commonly, IgE itself.
Type III hypersensitivity, in the Gell and Coombs classification of allergic reactions, occurs when there is accumulation of immune complexes (antigen-antibody complexes) that have not been adequately cleared by innate immune cells, giving rise to an inflammatory response and attraction of leukocytes.
In immunology, the Arthus reaction (/ ˌ ɑːr ˈ tj uː s /) is a type of local type III hypersensitivity reaction.Type III hypersensitivity reactions are immune complex-mediated, and involve the deposition of antigen/antibody complexes mainly in the vascular walls, serosa (pleura, pericardium, synovium), and glomeruli.
Urticarial vasculitis (also known as "chronic urticaria as a manifestation of venulitis", "hypocomplementemic urticarial vasculitis syndrome", "hypocomplementemic vasculitis" and "unusual lupus-like syndrome") [1] is a skin condition characterized by fixed urticarial lesions that appear histologically as a vasculitis.
Treatment of autoimmune disorders (e.g., SLE) include one or a combination of NSAIDs and hydroxychloroquine, azathioprine, methotrexate, mycophenolate, cyclophosphamide, low dose IL-2, intravenous immunoglobulins, and belimumab. Omalizumab is a monoclonal antibody that interacts with the binding site of the high-affinity IgE receptor on mast cells.
An autoimmune disease that causes pain and inflammation, lupus can affect your skin, as well as your kidneys, heart, joints and lungs. ... skin patch allergy tests and other diagnostic tools.

The hives and angioedema seen in CSU is thought to be linked to the degranulation of skin mast cells.
