摘要：In patients with idiopathic pulmonary fibrosis (IPF), the effects of antifibrotic agents on the prognosis remain unclear. This study aimed to investigate the impact of antifibrotic treatment on the risks of mortality, hospitalisation, and acute exacerbation in real-world patients with IPF. A total of 1213 IPF patients (biopsy-proven cases: 405) were included in this retrospective study. Propensity score matching was used to adjust for differences in baseline characteristics between patients who received antifibrotic treatment and who did not. A Cox proportional hazard model was used to compare the risks of all-cause mortality, hospitalisation, acute exacerbation, and mortality following acute exacerbation between the two groups. From the 1213 patients, 474 matched pairs were generated. The mean age of the patients in the matched cohort was 65.8 years and 82.8% were men. The median follow-up duration was 27 months. Antifibrotic treatment significantly reduced the risks of mortality [hazard ratio (HR), 0.59; 95% confidence interval (CI), 0.48–0.72; p < 0.001], all-cause hospitalisation (HR 0.71), respiratory-related hospitalisation (HR 0.67), acute exacerbation (HR 0.69), and mortality after acute exacerbation (HR 0.60). Our results suggest that antifibrotic treatment may reduce the risks of all-cause mortality, hospitalisation, acute exacerbation, and mortality after acute exacerbation in patients with IPF.
