Antifibrotics improve quality of life in idiopathic pulmonary fibrosis: Study

DENMARK: In terms of enhancing survival, treatment with nintedanib and pirfenidone was preferred to no antifibrotic medication, regardless of the intensity of the treatment, and a decreased dose seems like a reasonable alternative if the full amount is not tolerated, according to a study published in the Journal, Respiratory Medicine.

Idiopathic pulmonary fibrosis (IPF) is a persistent, interstitial lung disease with a high mortality rate that has no recognized cause. Two medications, nintedanib and pirfenidone, have been reported to slow the decline of Forced Vital Capacity (FVC), reduce acute exacerbations, and reduce hospitalization for respiratory events in recent years. Nevertheless, outside of pooled meta-analyses, no study has conclusively shown an impact on mortality. The effects of reducing the amount of an antifibrotic medication are unclear, yet many patients have their dosage reduced or their treatment stopped altogether due to negative effects.

The effect of antifibrotic therapy reduction on death in a significant real-life IPF cohort was retrospectively examined by the authors. From April 2016 to November 2021, 375 patients from the Danish PFBIO-cohort were monitored, with a median follow-up time of 1.84 years. Time until death from any cause was the analysis's main outcome. Based on treatment intensity (full, decreased, or no treatment), and the antifibrotic medication type (pirfenidone or nintedanib), five patient groups were established. Utilizing Cox proportional hazards analysis with baseline adjustments for age, sex, smoking status, and lung function, between group survival was compared.
