The diagnosis of SGS occurred in the absence of other features of active GPA in 15 of 34 patients (44\%): in 11 cases after and in 4 cases {\textendash} during immunosuppressive therapy (IST), when disease in other organs was in clinical remission. All patients underwent IDIT and in all it brings immediate improvement. The mean time of response duration since the last procedure was 42,6 months and the mean interval between sessions was 6,5 months. None of the patients required tracheostomy after beginning IDIT in our hospital.CONCLUSIONS: SGS often occurs independently of other features of active GPA. IDIT is a safe and an effective technique in the treatment of GPA {\textendash} related SGS. It should be performed in all GPA patients, who develope significant SGS, also in these with multi-organ disease concomitantly with immunosuppresive therapy. In patients with isolated SGS it allows to avoid IST and tracheostomy.}, issn = {0903-1936}, URL = {https://erj.ersjournals.com/content/48/suppl_60/PA3548}, eprint = {https://erj.ersjournals.com/content}, journal = {European Respiratory Journal} }
