Well in summary then vasculitis is a group
of disorders that causes inflammatory injury
and leads to destruction of blood vessels.
It can occur in arteries or veins. It's classified
by cause, vessel type, or vessel size. A typical
example of a medium-sized arteritis is Kawasaki’s
disease often seen in young children and often
involving the coronary arteries that can eventually
in later life lead to coronary aneurysms.
Common symptoms to the vasculitides involve
skin changes, bleeding into the skin, severe
malaise, fatigue, and fever. Many of these
diseases are thought to involve the immunological
systems and are treated often with steroids
and other immunosuppressive agents.
