The need for this studyis felt due to the fact that no study has been conducted in Iran to investigate the frequency, clinical, and laboratory symptoms ofvasculitis in the considerable population of vasculitis patients. The aim of this study was to evaluate the frequency and clinicalsigns of granulomatosis with polyangiitis (GPA) patients who were admitted to the rheumatology ward in Valiasr Hospital, Tehran,Iran, over the last 10 years.In this study, all patients were evaluated with a possible diagnosis of vasculitis having been admitted to the rheumatology ward ofValiasr Hospital over the past ten years. These GPA patients were evaluated for clinical, laboratory, radiological, and pathologicalfindings, as well as for outcome, mortality, and major complications.Over the last 10 years, 223 vasculitis patients have been admitted to Valiasr Hospital and of these, 87% were primary vasculitis and13% were secondary vasculitis. The highest frequency was related to GPA (21.52%) followed by Behcet's disease. GPA patientswere women and men at 52.08% and 47.91%, respectively. Upper and lower airway involvement and total ear, nose, and throat(ENT) involvement was the most common clinical symptoms in GPA patients.According to the findings of this study, GPA vasculitis was the most common type of vasculitis and ENT involvements were themost common clinical symptoms in this patient. However, more studies are required to confirm these data in Iran. %U https://www.rheumres.org/article_118156_482c08c9ba63dc0edea36f43e66c4645.pdf
