Vasculitis is a condition characterized by inflammation of blood vessels, which can impact both capillaries and large arteries such as the aorta, the main blood vessel for blood leaving the heart. Inflammation causes the walls of the blood vessels to thicken, potentially leading to a narrowing of the vessel’s passage. When blood flow is restricted, it can result in damage to organs and tissues.
Blood vessels that are inflamed may weaken and enlarge, which can result in aneurysms. Additionally, the vessels may get so thin that they burst, causing bleeding into the tissue. Blood vessels may narrow to the point of completely closing off (an occlusion) as a result of vasculitis. When the blood flow in a vessel affected by vasculitis is diminished or stopped, the tissues that depend on that vessel for blood supply experience damage and initiate a process of tissue death.
Vasculitis manifests in various types, many of which are uncommon. It can involve multiple organs or be limited to a single organ. The duration of the condition can range from temporary to long term.
Vasculitis can affect anyone, though some forms are more prevalent in particular age groups. Depending on the type they have, they might get better on their own. The majority of vasculitis types necessitate the use of medications to manage inflammation and minimize the occurrence of flare–ups.
The following types of Vasculitis include the following.
Commonly, most types of vasculitis present with the following typical signs and symptoms:
Additional symptoms may arise depending on the specific body part affected by vasculitis. When vasculitis impacts small blood vessels in the skin, it can lead to the rupture of these vessels, resulting in small spots of bleeding in the tissue. The following signs and symptoms are associated with the involved body parts:
If individuals experience any worrisome signs or symptoms, it is advisable for them to schedule a medical checkup. Early detection is crucial for effective treatment of various types of vasculitis.
The exact cause of vasculitis remains unknown. Certain types of vasculitis can be influenced by an individual’s genetic makeup, while others occur due to the immune system mistakenly attacking cells within the blood vessels. This immune system reaction may be triggered by various factors, including infections such as hepatitis B and hepatitis C, blood cancers, immune system diseases like rheumatoid arthritis, lupus, and scleroderma, as well as certain drug reactions.
Anyone can develop vasculitis. Some factors that might increase the likelihood of developing specific diseases include:
