Causes of Microscopic Polyangiitis
Understanding the causes of microscopic polyangiitis can be challenging as there is currently no known definitive cause for this condition. It is not considered to be inheritable, nor is it a form of cancer or contagious. However, researchers believe that the immune system plays a significant role in its development.
Microscopic polyangiitis is classified as an ANCA-associated vasculitis, which means that the immune system is believed to become overactive in individuals with this condition. This hyperactive immune response leads to the body mistakenly attacking its own blood vessels and tissues.
While the exact trigger for this immune system dysfunction is still unclear, experts continue to explore various factors that may contribute to the development of microscopic polyangiitis. Research in this area aims to provide a better understanding of the condition and potentially discover new treatment options.
Complications
Untreated microscopic polyangiitis can lead to long-term organ damage. The kidneys are most commonly affected, resulting in kidney failure. However, any organ that comes into contact with the inflamed blood vessels can be damaged. The lungs can be affected as well, leading to breathing difficulties. Severe complications can be identified by symptoms such as dark or cloudy urine and coughing up blood.
