Vasculitis
Urgent
Vasculitis is a group of disorders characterized by inflammation of blood vessel walls. Inflammation can cause blood vessels to become narrowed, weakened, blocked, or scarred, reducing blood flow to tissues and organs. Symptoms vary widely according to the vessels and organs affected and may include fever, fatigue, weight loss, skin changes, joint or muscle symptoms, nerve problems, kidney abnormalities, or organ-specific symptoms. Some forms affect small areas, while others can involve multiple organs.

When to Seek Medical Attention
Vasculitis requires medical assessment because inflammation of blood vessels can affect multiple organs. Seek prompt care for persistent fever, unexplained weight loss, worsening weakness, new rash, joint symptoms, blood in the urine, breathing problems, or neurological changes. Emergency assessment is needed for severe breathing difficulty, chest pain, sudden weakness or confusion, major bleeding, severe abdominal pain, or rapidly worsening organ function.

Overview
Vasculitis is a group of disorders characterized by inflammation of blood vessel walls. Inflammation can cause blood vessels to become narrowed, weakened, blocked, or scarred, reducing blood flow to tissues and organs. Symptoms vary widely according to the vessels and organs affected and may include fever, fatigue, weight loss, skin changes, joint or muscle symptoms, nerve problems, kidney abnormalities, or organ-specific symptoms. Some forms affect small areas, while others can involve multiple organs.

Causes 3
Vasculitis occurs when abnormal immune activity causes inflammation of blood vessel walls. Some forms are primary disorders in which no single underlying cause is identified. Other forms may occur in association with infections, medicines, autoimmune diseases, or other inflammatory conditions. The inflammation can damage the vessel wall and interfere with normal blood flow. Different forms of vasculitis affect different sizes and types of blood vessels and therefore produce different patterns of organ involvement.
Autoimmune Disorder
Genetics
Infection
Risk Factors
Risk factors vary substantially according to the type of vasculitis. They may include autoimmune diseases, certain infections, exposure to particular medicines, smoking, family history, and other underlying inflammatory or medical conditions. Some forms occur more frequently in particular age groups or populations. Having a risk factor does not mean that vasculitis will develop, and many people with vasculitis have no clearly identifiable preventable trigger.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis depends on the suspected type of vasculitis and the organs involved. Evaluation may include a complete blood count, inflammatory markers, kidney and liver tests, urine testing, and selected antibody or infection studies. Imaging may be used to examine affected blood vessels or organs. In some cases, biopsy of affected skin, kidney, nerve, muscle, lung, or another tissue is needed to confirm inflammation and determine the specific pattern. The diagnostic approach is individualized according to symptoms and suspected organ involvement.
Prevention
Key Prevention Tips
Many forms of vasculitis cannot be prevented because their causes are unknown or involve abnormal immune activity
When a specific trigger is identified, avoiding that trigger may reduce the risk of recurrence
Not smoking, managing associated autoimmune or other medical conditions, taking prescribed medicines as directed, and attending recommended follow-up can help reduce complications
New or worsening symptoms should be assessed promptly because inflammation affecting major organs or blood vessels may require timely treatment
Prevention Guidance
Many forms of vasculitis cannot be prevented because their causes are unknown or involve abnormal immune activity. When a specific trigger is identified, avoiding that trigger may reduce the risk of recurrence. Not smoking, managing associated autoimmune or other medical conditions, taking prescribed medicines as directed, and attending recommended follow-up can help reduce complications. New or worsening symptoms should be assessed promptly because inflammation affecting major organs or blood vessels may require timely treatment.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
