Association between acute exacerbation and progressive pulmonary fibrosis in interstitial lung disease: a retrospective cohort study.

ABSTRACT:

Background

Acute exacerbation (AE) refers to rapidly progressive respiratory deterioration in the clinical course of interstitial lung disease (ILD). Progressive pulmonary fibrosis (PPF) is the chronic progressive phenotype of ILD. No study has investigated the relationship between AE and PPF in ILD.

Objectives

We aimed to determine the association between AE and PPF in ILD patients.

Design

A retrospective cohort study.

Methods

A total of 414 patients hospitalised for ILD were included in our study. The clinical presentations, radiographic features and laboratory findings of the patients were reviewed.

Results

AE was present in 120 (29.0%) ILD patients and was associated with a higher risk of death than non-AE patients in the whole cohort (HR 2.893; 95%
