Abstract
PURPOSE OF REVIEW: Summarize recent evidence on the identification and management of rheumatoid arthritis-associated interstitial lung disease (RA-ILD). RECENT FINDINGS: Clinical and subclinical interstitial lung disease (ILD) are frequent extra-articular manifestations of rheumatoid arthritis (RA). Better means of identifying and treating RA-ILD are needed to improve the prognosis, with a median survival of only 3-7 years after diagnosis. Several serum biomarkers are currently being evaluated for their ability to detect RA-ILD. Thorough evaluation and multidisciplinary discussion remains the gold standard for establishing the diagnosis of RA-ILD. Management is challenging with most RA disease-modifying antirheumatic drugs (DMARDs) linked to pneumonitis. Methotrexate is typically avoided in clinically significant ILD, although alternative therapies including leflunomide and biologic DMARDs also carry risks in RA-ILD. Antifibrotics appear to slow the progression of ILD, and a large phase II trial exclusively in RA-ILD is underway. In addition, smoking cessation, pulmonary rehabilitation, oxygen therapy, managing comorbidities, and lung transplantation evaluation are vital to improving patient outcomes in RA-ILD. SUMMARY: With little high-quality evidence to guide the management of RA-ILD, multidisciplinary teams with expertise in RA-ILD are highly valuable for diagnosing and treating RA-ILD. Clinical and translational research in RA-ILD is needed to fill the many evidence gaps.
