Key clinical point: Patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) were at an increased risk for mortality, with age, chronic obstructive pulmonary disease (COPD), diabetes mellitus with end-organ damage (DM-EOD), and corticosteroid dose being the major risk factors.
Major finding: Risk for mortality was higher in patients with RA-ILD vs RA without ILD (adjusted hazard ratio [aHR] 4.38; 95% CI 2.03-9.43). Age at ILD diagnosis (aHR 1.05; P < .001), comorbidities, such as COPD (aHR 2.12; P = .005) and DM-EOD (aHR 33.85; P = .002), and average daily prednisolone dose (aHR 1.09; P < .001) were associated with an increased risk for mortality in patients with RA-ILD.
Study details: Findings are from a population-based cohort study including patients with RA-ILD (n = 214) and RA without ILD (n = 30,882) who were propensity-matched (1:1) for selected comorbidities.
Disclosures: This study did not receive any funding. No conflicts of interest were declared.
