What are the causes of Vasculitis?
The cause for many types of vasculitis is not known. In some cases, the immune system recognizes the body’s own blood vessels as foreign particle and starts acting against it, leading to swelling or leak of blood from the vessel.
An allergic reaction to a medication, such as an antibiotic or diuretic, may also cause vasculitis. Hepatitis C and Hepatitis B infection can cause Cryoglobulinaemia and Polyarteritis nodosa respectively. Vasculitis can also occur as a result of certain immune disorders like rheumatoid arthritis, lupus and Sjogren's syndrome.
