What kind of vasculitis is granulomatosis with polyangiitis?

Granulomatosis with polyangiitis ( GPA ), formerly known as Wegener’s granulomatosis ( WG ), is a long-term systemic disorder that involves the formation of granulomas and inflammation of blood vessels (vasculitis). It is a form of vasculitis that affects small- and medium-size vessels in many organs…

The revised Five-factor score is associated with 5-year mortality from GPA and is based on the following criteria: age greater than 65 years, cardiac symptoms, gastrointestinal involvement, chronic kidney disease, and the absence of ears, nose, and throat symptoms. With corticosteroids and cyclophosphamide, 5-year survival is over 80%.

How does granulomatosis cause damage to the endothelium?

In vitro studies have found that ANCAs can activate neutrophils, increase their adherence to endothelium, and induce their degranulation that can damage endothelial cells. In theory, this phenomenon could cause extensive damage to the vessel wall, in particular of arterioles.
