Kaplan–Meier survival curves in patients with AE-SAID-ILD. A) Ninety-day survival rate in patients with AE-SAID-ILD. B) Ninety-day survival was unaffected by the presence of PF-ILD (log-rank p = 0.316). Ninety-day survival according to C) GAP stage (p = 0.030) and D) JRS severity stage (p = 0.039) within 12 months before AE. Ninety-day survival in relation to E) peripheral WBC count (p = 0.006) and F) neutrophil count (p = 0.002). All patients received steroid-pulse therapy followed by a tapering dose of prednisolone. Ninety-day survival in relation to addition of G) immunosuppressants, mainly intravenous cyclophosphamide (p = 0.968) and H) PMX-DHP within 3 days after admission (p = 0.022). Abbreviations: AE-SAID-ILD: acute exacerbation of systemic autoimmune disease-related interstitial lung diseases, PF-ILD: progressive fibrosing interstitial lung disease, GAP: gender, age, and physiology, JRS: Japanese Respiratory Society, PMX-DHP: direct haemoperfusion with a polymyxin B-immobilised fibre column
