The outlook depends on the specific type of vasculitis:

  • Polyarteritis nodosa The disease is treated successfully in up to 90 percent of patients.

  • Hypersensitivity vasculitis Most cases go away on their own, even without treatment. Rarely, the disease returns.

  • Giant cell arteritis The disease goes away in most people, but many require one or more years of prednisone therapytreatment.

  • Granulomatosis with polyangiitis (Wegener's) Wegener's granulomatosis At one time, this illness was almost always fatal. Now, with proper treatment, 90 percent of people have significant relief of symptoms and the disease goes away completely in about 75 percent of patients.

  • Takayasu's arteritis For mild cases, the long-term prognosis is good. Overall, the 5-year survival is about 80 to 90 percent.

  • Kawasaki disease The outlook is excellent. Less than 3 percent of people with this disease develop fatal complications.
