Microscopic Polyangiits (MPA) is a very rare and serious disease that causes inflammation of the small blood vessels. This can impact tissues and organs throughout the body and cause a wide variety of symptoms.
MPA belongs to a family of arthritic diseases called vasculitis. The word vasculitis means inflammation of blood vessels. The most common affected by MPA include the skin, joints, nerves, and kidneys.
Early diagnosis and medical therapy are essential for managing MPA.
It is not known what causes MPA but it is thought to be an autoimmune disease which occurs when the body’s immune system attacks its own healthy cells and tissues. The reasons why the body might start attacking its small blood vessels is not well understood.
MPA can affect anyone but it is more common in younger and middle-aged people.
