Abstract
Background
Although corticosteroid therapy with dose tapering is the most commonly used treatment for acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF), there is no consensus on the tapering regimen. This study aimed to investigate the association between early corticosteroid dose tapering and in-hospital mortality in patients with AE-IPF.
Methods
In this retrospective cohort study, we analyzed the data of a cohort from eight Japanese tertiary care hospitals and routinely collected administrative data from a cohort from 185 Japanese hospitals. Patients with AE-IPF were classified into the early and non-early tapering groups depending on whether the maintenance dose of corticosteroids was reduced within two weeks of admission. Propensity score analysis with inverse probability weighting (IPW) was performed to estimate the effect of early corticosteroid dose tapering.
Results
The multi-center cohort included 153 eligible patients, of whom 47 (31%) died, whereas the administrative cohort included 229 patients, of whom 51 (22%) died. Patients with early tapering tended to have a better prognosis than those without it (unadjusted hazard ratio [95% confidence interval] 0.41 [0.22–0.76] and 0.65 [0.36–1.18] in the multi-center and administrative cohorts, respectively). After IPW, the early tapering group had a better prognosis than the non-early tapering group (IPW-adjusted hazard ratio [95% confidence interval] 0.37 [0.14–0.99] and 0.27 [0.094–0.83] in the multi-center and administrative cohorts, respectively).
Conclusion
Early corticosteroid dose tapering was associated with a favorable prognosis in patients with AE-IPF. Further studies are warranted to confirm the effects of early corticosteroid dose tapering in patients with AE-IPF.
