title: Long-term survival of patients with Wegener's granulomatosis from the American College of Rheumatology Wegener's Granulomatosis Classification Criteria Cohort.
abstract: OBJECTIVE
  To determine survivorship in Wegener's granulomatosis (WG) in a well-defined multicenter cohort.
  
  
  METHODS
  Follow-up was obtained for 77 of the 85 patients enrolled in the 1990 American College of Rheumatology vasculitis classification study.
  
  
  RESULTS
  There were 28 deaths (10 females and 18 males) among the 77 patients available for follow-up. Standardized mortality ratios (SMR) were calculated with mortality data from the general population and from this group of patients with WG (an SMR of 1 indicates that expected and observed survival are identical). Overall survivorship among patients with WG was substantially reduced in this cohort (SMR = 4.685 +/- 0.65; for females SMR = 6.814 +/- 1.571; for males SMR = 3.998 +/- 0.69).
  
  
  CONCLUSIONS
  The life expectancy of patients with WG is reduced compared with the general population.
