Overview
Prognosis
25 to 40% of patients suffer from flare-ups, but a majority responds well to treatment. Anatomical problems (sinusitis, tracheal stenosis) may require surgery in a small proportion. Relapses can be long and troublesome. With the appropriate treatment, the outlook is good for people with Wegener's granulomatosis. In a study of 158 patients who were treated with prednisone and cyclophosphamide at the National Institutes of Health (NIH), 91 percent of them markedly improved. After 6 months to 24 years of follow-up, 80 percent of the patients survived.
Approximately half of people with Wegener's granulomatosis may experience a return of their disease. This occurs most frequently within 2 years of stopping medicine but can occur at any point both during treatment or after stopping treatment. Thus, it is extremely important that people continue to see their doctors regularly, both while they are on these medicines, as well as after the medicines have been stopped.
Complications
Long-term complications are very common (86%): mainly chronic renal failure, hearing loss and deafness.
