What is vasculitis?
Vasculitis is an inflammation of the blood vessels that can affect any blood vessel in any part of the body. The inflammation can be limited to one location within a blood vessel, or spread throughout an organ or tissue, so symptoms of vasculitis can affect every major body system. Vasculitis is not a disease, but a process that occurs in the course of many other diseases
Each of the vasculitis diseases (also, as a group, referred to as vasculitides) is defined by certain patterns of distribution of blood vessel involvement, particular organ involvement, and laboratory test abnormalities. There are a number of types of vasculitis. Some types of vasculitis are the result of an underlying disease, and these are known as secondary vasculitides. Others occur without a known cause and are called primary vasculitides.
Vasculitis can affect people of all ages. Some age groups are affected more than others, depending on the type of vasculitis. There also are geographical and ethnic differences in the incidence of vasculitis. For example, giant cell arteritis is the most common vasculitis in the United States, and Takayasu's arteritis is more common in Asian countries. However, all types of vasculitis are rare. Though some forms of vasculitis improve on their own, others require treatment - often including taking medications for an extended period of time.
