Full Press Release Details
ANCA-Associated Vasculitis (AAV) is a group of autoimmune diseases causing inflammation of small to medium blood vessels, leading to organ damage in the kidneys, lungs, skin, eyes, and nervous system. The three main types are:
GPA
Involves granulomas and commonly affects the kidneys, lungs, and upper airways.
MPA
Similar to GPA but without granulomas, often with more severe kidney involvement.
EGPA
Features granulomas and high eosinophil levels, typically impacting the lungs and sinuses.
