RA-ILD: Tracking Function and CT
Conventional monitoring markers do not change before deaths in this predominantly mild cohort.
A prospective cohort study of patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) revealed that pulmonary function and imaging measures remained stable over two years, despite an 8% mortality rate. Conducted across three Brazilian centers, the study included 105 patients, focusing on pulmonary fibrosis and associated biomarkers. Although 80% of participants had pulmonary fibrosis, most exhibited mild disease, with no significant decline in forced vital capacity. The findings challenge traditional expectations of functional decline preceding mortality in ILD cases.
1. 105 RA-ILD patients were studied over 24 months. 2. 8% mortality rate recorded, largely unrelated to pulmonary decline. 3. Majority exhibited mild RA-ILD with 80% having pulmonary fibrosis. 4. FVC remained stable at 76% across the study. 5. 12% improved, 69% stable, and 19% worsened at 24 months in imaging assessments. 6. Challenges conventional views on ILD mortality patterns. 7. Study's limitations include sample size and follow-up issues due to COVID-19.
