Vasculitis is primarily caused by autoimmune disorders or triggered by infections like COVID-19.
Here's a breakdown of the causes of vasculitis:
-
Autoimmune Disorders:
- Diseases such as lupus, rheumatoid arthritis, and scleroderma can trigger vasculitis. In these conditions, the body's immune system mistakenly attacks its own blood vessels, leading to inflammation.
-
Infections:
- Certain infections, including COVID-19, can increase the risk of developing vasculitis or cause flares in individuals with a history of the condition.
In summary, vasculitis is often the result of an overactive or misdirected immune response, either due to autoimmune diseases or triggered by infections.
