Wegener’s granulomatosis (WG) is a rare disease that causes the walls of blood vessels to become inflamed, a condition called vasculitis. This limits blood flow to tissues and can affect any organ. The outlook is good with proper treatment, but without it, WG is fatal.
WG is a type of autoimmune disease. This means the body’s immune system attacks its own tissues. The cause is unknown.
WG does not appear to be passed from one generation to the next. It is more common in Caucasians, and in people of middle age.
Symptoms and their severity vary from one person to another. In most cases, ear, nose, and throat symptoms appear first. These symptoms do not respond to normal treatment and worsen over time.
WG can cause common cold- or flu-like symptoms such as:
Common respiratory tract symptoms associated with WG may include:
