Systemic vasculitis

Systemic Vasculitis is a form of vasculitis—a group of disorders that destroy blood vessels by inflammation. It can affect any type of blood vessel—arteries, arterioles, veins, venules, or capillaries. Systemic vasculitis can cause changes in the walls of blood vessels, such as inflammation, weakening, narrowing, or scarring. These changes can restrict blood flow, resulting in organ and tissue damage.

Causes

The exact cause of systemic vasculitis is unknown. However, it's believed to involve the immune system attacking the blood vessels, often triggered by an infection or medication. Autoimmune diseases, such as rheumatoid arthritis and lupus, can also cause systemic vasculitis.

Symptoms

Symptoms of systemic vasculitis can vary greatly depending on the organs affected and the severity of the disease. Common symptoms include fatigue, fever, weight loss, muscle and joint pain, and nerve problems like numbness or weakness.

Diagnosis

Diagnosis of systemic vasculitis involves a thorough medical history and physical examination, blood tests, imaging tests such as X-rays, CT scans, or MRIs, and sometimes a biopsy of affected tissue.

Treatment

Treatment for systemic vasculitis aims to reduce inflammation in the affected blood vessels and treat any underlying cause of the disease. This often involves medications such as corticosteroids and immunosuppressants. In severe cases, surgery may be needed to repair damaged blood vessels.

Prognosis

The prognosis for systemic vasculitis varies depending on the severity of the disease and the organs affected. Early diagnosis and treatment can significantly improve the prognosis.
