C-ANCA
C-ANCA or Cytoplasmic Anti-Neutrophil Cytoplasmic Antibodies are a type of autoantibody that are primarily associated with certain types of autoimmune diseases, including Granulomatosis with polyangiitis and Microscopic polyangiitis. These antibodies are detected in the blood of patients with these diseases and are used as a diagnostic marker.
Overview[edit | edit source]
C-ANCA targets a protein called proteinase 3, which is present in neutrophils, a type of white blood cell. The presence of these antibodies can lead to the destruction of neutrophils, causing inflammation and damage to blood vessels, particularly in the lungs and kidneys.
Clinical Significance[edit | edit source]
C-ANCA is primarily used as a diagnostic marker for certain types of vasculitis, particularly Granulomatosis with polyangiitis and Microscopic polyangiitis. It is also occasionally found in patients with other autoimmune diseases, such as Rheumatoid arthritis and Inflammatory bowel disease.
Testing[edit | edit source]
Testing for C-ANCA involves a blood test. The presence of these antibodies in the blood can indicate an autoimmune disease. However, not all patients with these diseases will have detectable levels of C-ANCA, and the test can sometimes give false positive results. Therefore, it is usually used in conjunction with other tests and clinical findings to diagnose these conditions.
Treatment[edit | edit source]
Treatment for conditions associated with C-ANCA typically involves medications to suppress the immune system and reduce inflammation. This may include corticosteroids, immunosuppressants, and biologic therapies.
