التهاب الأوعية الدموية

Overview 

Vasculitis Disease refers to a group of conditions that cause inflammation of blood vessels, including arteries, veins, and capillaries. This inflammation can lead to thickening, weakening, narrowing, or scarring of the vessel walls, affecting blood flow to various organs.

Depending on the type and severity, vasculitis can involve one or multiple organs such as the skin, lungs, kidneys, brain, or joints. Early diagnosis and proper treatment are essential to prevent organ damage and complications.

Types of Vasculitis

• Large Vessel Vasculitis: Affects major arteries (e.g., giant cell arteritis)
• Medium Vessel Vasculitis: Involves medium-sized arteries (e.g., polyarteritis nodosa)
• Small Vessel Vasculitis: Affects small blood vessels (e.g., granulomatosis with polyangiitis)
• Primary Vasculitis: Occurs on its own
• Secondary Vasculitis: Triggered by infections, medications, or other diseases

Symptoms of Vasculitis

• Fever and fatigue
• Weight loss
• Muscle and joint pain

• Headaches

Causes of Vasculitis

• Autoimmune response (body attacking its own blood vessels)
• Infections (viral or bacterial)
• Certain medications
• Chronic diseases (e.g., lupus, rheumatoid arthritis)
• Genetic and environmental factors

Complications of Vasculitis

• Organ damage (kidneys, lungs, brain)
• Blood clots
• Aneurysm (weakening and bulging of vessels)
• Nerve damage
• Stroke
• Vision loss (in some types)

Risk Factors of Vasculitis

• Autoimmune disorders
• Chronic infections
• Family history
• Certain medications
• Age (varies by type)
• Smoking

Prevention of Vasculitis

• Manage underlying autoimmune conditions
• Avoid unnecessary medications
• Maintain a healthy lifestyle
• Regular medical check-ups
• Early treatment of infections
