Introduction: To evaluate long-term outcome of patients with granulomatous polyangitis (GPA) followed up in a tertiary university hospital. Patients and Methods: We reviewed medical records of 22 patients with GPA diagnosis confirmed by tissue biopsies between 2004 and 2014. Results: The mean time from the onset of symptoms to diagnosis was 7.8 +/- 12.3 months [interquartile range (IR)= 4.0]. The most commonly involved organs were the upper respiratory tract (URT) (72.7%), lower respiratory tract (81.8%) and kidneys (72.7%). URT involvement indicated good prognosis (p= 0.046). Survival in the patients with and without URT involvement was 124.6 +/- 6.9 months and 59.7 +/- 22.9 months, respectively. End-stage renal failure (ESRF) requiring dilaysis and cardiac involvement were associated with mortality (p= 0.022 and p= 0.026, respectively). Of the 12 dialysis-dependent patients at diagnosis, 11 survived > 3 months and seven regained renal function permanently. Dialysis dependency was significantly lower in patients who received plasmapheresis (p= 0.047). Overall mortality rate was 18% (4/22). Mean survival was 55.9 +/- 42.8 months (IR= 84.0). Conclusion: Diagnosis of GPA may be delayed by the nonspecific nature of its symptoms. URT involvement was associated with good prognosis, whereas cardiac involvement and ESRF requiring dialysis were associated with poor outcome. Plasmapheresis may increase the rate of renal recovery in the patients with ESRF requiring dialysis.
