Necrotizing vasculitis

Definition

Necrotizing vasculitis is a rare condition that involves inflammation of the blood vessel walls.

Alternative Names

Vasculitis - necrotizing

Causes, incidence, and risk factors

Necrotizing vasculitis is common with:

It is very rare in children.

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.

Necrotizing vasculitis may affect any blood vessel in the body. Therefore, it can cause problems with the skin or any of the body's organs.

Symptoms

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.

Treatment

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.

For severe disease, cyclophosphamide (Cytoxan) is usually given. A new medicine, rituximab, (Rituxan) may be used instead of Cytoxan.

Related conditions include:

Expectations (prognosis)

The outcome depends on the location of the vasculitis and the severity of tissue damage.

Complications

  • Permanent damage to the structure or function of the affected area
  • of necrotic tissuesSecondary infections
