Vasculitis is a group of disorders that destroy blood vessels by inflammation. [2] Both arteries and veins are affected. Lymphangitis (inflammation of lymphatic vessels) is sometimes considered a type of vasculitis. [3] Vasculitis is primarily caused by leukocyte migration and resultant damage.
It is an autoimmune disease and a form of vasculitis that affects small- and medium-sized vessels in many organs, but most commonly affects the upper respiratory tract, lungs, and kidneys. [6] The signs and symptoms of GPA are highly varied and reflect which organs are supplied by the affected blood vessels.
This article provides a list of autoimmune diseases. These conditions, where the body's immune system mistakenly attacks its own cells, affect a range of organs and systems within the body. Each disorder is listed with the primary organ or body part that it affects and the associated autoantibodies that are typically found in people diagnosed ...
The autoimmune condition is characterized by inflammation of the blood vessels and can be life-threatening. What is vasculitis? Ashton Kutcher's rare disease explained
A key difference is a malfunction of the innate immune system in autoinflammatory diseases, whereas in autoimmune diseases there is a malfunction of the adaptive immune system. [ 8 ] Symptoms of autoimmune diseases can significantly vary, primarily based on the specific type of the disease and the body part that it affects.
The disease spectrum varies from failure of multiple organs to involvement of a single organ. Almost any organ could be impacted; however, polyarteritis nodosa rarely affects the lungs for unknown reasons. [10] Kawasaki disease (KD) is a type of systemic vasculitis of medium-sized vessels with an acute onset that primarily affects young children.
Autoimmune diseases can be broadly divided into systemic and organ-specific or localised autoimmune disorders, depending on the principal clinico-pathologic features of each disease. Systemic autoimmune diseases include coeliac disease , lupus erythematosus , Sjögren syndrome , scleroderma , rheumatoid arthritis , cryoglobulinemic vasculitis ...
In the setting of systemic vasculitis as described above, proliferative nephritis is associated with antineutrophil cytoplasmic antibodies (ANCA). [3] Because of this, an ANCA test should always follow a negative immunofluorescence result to have the highest accuracy for confirming pauci-immune vasculitis-driven proliferative nephritis. [1]
