Key clinical point: Nearly half of the patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) showed radiographic progression of fibrosis, and the presence of diabetes mellitus, high disease activity, and advanced high-resolution computed tomography (HRCT) scores significantly increased the fibrotic progression risk.
Major finding: HRCT-based radiographic progression of fibrosis was observed in 51.0% of patients with RA-ILD, with diabetes mellitus (hazard ratio [HR] 2.47; P < .01), Disease Activity Scores in 28 Joints-Erythrocyte Sedimentation Rate > 5.1 (HR 2.32; P = .04), and baseline HRCT scores > 5 (HR 3.04; P < .01) being significant risk factors for fibrotic progression.
Study details: Findings are from a retrospective cohort study including 371 patients with RA, of which 32.3% had RA-ILD.
Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.
