Clinical impacts of COVID-19 on severe exacerbation and mortality in interstitial lung disease: prognosis 30 days after infection

초록

Results: During a mean follow-up of 7.4 months, the COVID-19 cohort had a higher risk of severe exacerbation compared to controls (aHR 2.26, 95% CI 1.38-3.69). During a mean follow-up of 19.6 months, the COVID-19 cohort had a higher risk of death (aHR 2.79, 95% CI 1.63-4.79) compared to controls. When considering COVID-19 severity, the severe COVID-19 group had a higher risk of severe exacerbation and death compared to controls, while the non-severe COVID-19 group did not show increased risk of severe exacerbation or death. In analyses based on ILD subtype, individuals with idiopathic pulmonary fibrosis in the COVID-19 cohort had the highest risk of severe exacerbation and death. Conclusions: Previous severe COVID-19 was associated with worse clinical outcomes in individuals with ILD, especially in patients with idiopathic pulmonary fibrosis.
