The full form of MPA disease is Microscopic Polyangiitis.
Microscopic polyangiitis (MPA) is a rare autoimmune disease characterized by inflammation of small blood vessels (vasculitis). This inflammation can affect various organs, most commonly the kidneys, lungs, skin, nerves, and joints, leading to organ damage.
Here's a breakdown:
- Microscopic: Refers to the fact that the inflammation primarily affects small blood vessels, which can only be seen under a microscope.
- Polyangiitis: Indicates inflammation of many (poly-) blood vessels (angiitis).
Because MPA is an autoimmune disease, the body's immune system mistakenly attacks its own blood vessels, causing inflammation and damage. This can lead to a range of symptoms depending on the organs affected.
