In short ...

Vasculitides (also called vasculitis) are rare and complex diseases. They can be primary (without an identifiable cause) or secondary (caused by an infection, medication, other disease).

Vasculitis causes inflammation in the walls of blood vessels (most often arteries, but sometimes also veins). There are different vasculitis which can all be systemic (affecting several organs) or localized (1 or 2 organs).

Quick treatment is necessary in order to be able to prevent damage which can then become irreversible.

Organs most commonly affected by vasculitis include  : skin, lungs, kidneys, nose and sinuses, nervous system (nerves and sometimes brain), heart, digestive system and joints.

There are over 20 types of vasculitis, however the most common include  :


Giant cell arteritis (temporal arteritis)

Takayasu arteritis

Polyarteritis nodosa

Kawasaki arteritis

Isolated cutaneous vasculitis (leukocytoclastic vasculitis)

ANCA-associated vasculitis (AAV):

-  Granulomatosis with polyangiitis (GPA, formerly Wegener)

-  Microscopic polyangiitis

-  Granulomatosis with polyangiitis and eosinophilia (formerly Churg-Strauss)

Vasculitis IgA (formerly Henoch-Shönlein)
