Vasculitis is a condition in which the walls of blood vessels thicken and scar due to chronic inflammation. Vasculitis can affect different organs or parts of the body. When the blood vessel is damaged, it may close, blocking blood flow to the tissue or organ it supplies.


The cause of vasculitis is unknown, but it is often related to infections, autoimmune diseases, and certain cancers. It can also occur as a reaction to certain medications. It is common among patients who suffer from rheumatoid arthritis, lupus, hepatitis B or C, and leukemia.


Symptoms of vasculitis vary depending on which part of the body or organ is infected. Initial symptoms include fever, chills, fatigue, or weight loss. Symptoms appearing on the skin can include small lesions, discolorations, pain, tenderness, or sores that do not heal. Some patients may also experience tingling in the arms or legs, joint pain, muscle contractions, or abdominal pain.


Treatment for vasculitis may include the use of corticosteroids or other drugs that suppress the immune system. Proper diagnosis is essential to determine which organs or body areas are affected and devise a proper treatment plan.
