Learn About Necrotizing Vasculitis

What is the definition of Necrotizing Vasculitis?

Necrotizing vasculitis is a group of disorders that involve inflammation of the blood vessel walls. The size of the affected blood vessels helps to determine the names of these conditions and how the disorder causes disease.

What are the causes of Necrotizing Vasculitis?

Necrotizing vasculitis may be the primary condition such as polyarteritis nodosa or granulomatosis with ANCA associated vasculitis (formerly called Wegener granulomatosis). In other cases, the vasculitis may occur as part of another disorder, such as systemic lupus erythematosus or hepatitis C.

The cause of the inflammation is unknown. It is likely related to autoimmune factors. The wall of the blood vessel may scar and thicken or die (become necrotic). The blood vessel may close, interrupting blood flow to the tissues it supplies. The lack of blood flow will cause the tissues to die. Sometimes the blood vessel may break and bleed (rupture).

Necrotizing vasculitis may affect blood vessels in any part of the body. Therefore, it can cause problems in the skin, brain, lungs, intestines, kidney, brain, joints or any other organ.

What are the symptoms of Necrotizing Vasculitis?

Fever, chills, fatigue, arthritis, or weight loss may be the only symptoms at first. However, symptoms may be in almost any part of the body.


  • Red or purple colored bumps on the legs, hands or other parts of the body
  • Bluish color to the fingers and toes

  • Leg pain
  • Muscle weakness

Brain and nervous system:

  • Pain, numbness, tingling in an arm, leg, or other body area

What are the current treatments for Necrotizing Vasculitis?

Corticosteroids are given in most cases. The dose will depend on how bad the condition is.

Other drugs that suppress the immune system may reduce inflammation of the blood vessels. These include azathioprine, methotrexate, and mycophenolate. These medicines are often used along with corticosteroids. This combination makes it possible to control the disease with a lower dose of corticosteroids.

For severe disease, cyclophosphamide (Cytoxan) has been used for many years. However, rituximab (Rituxan) is equally effective and is less toxic.

Recently, tocilizumab (Actemra) was shown to be effective for giant cell arteritis so the dose corticosteroids could be reduced.

What is the outlook (prognosis) for Necrotizing Vasculitis?

Necrotizing vasculitis can be serious and life-threatening disease. The outcome depends on the location of the vasculitis and the severity of tissue damage. Complications may occur from the disease and from the medicines. Most forms of necrotizing vasculitis require long-term follow-up and treatment.

What are the possible complications of Necrotizing Vasculitis?

Complications may include:

  • Permanent damage to the structure or function of the affected area
  • Secondary infections of necrotic tissues
  • Side effects from medicines used
