Management of Interstitial Lung Disease in Patients With Myositis Specific Autoantibodies

Research output: Contribution to journalReview articlepeer-review

Abstract

Purpose of Review: To review advances in the management of idiopathic inflammatory myopathy-associated interstitial lung disease (IIM-associated ILD) in the past 5 years, with highlights in myositis-specific antibody (MSA) groups. Recent Findings: With the recent advent of widespread MSA testing, the study of specific homogeneous autoantibody-based subgroups of IIM-associated ILD is now possible. The prevalence, severity, prognosis, and response to treatment are under study for these individual MSAs. Early evidence suggests that PL-7- and PL-12-positive patients are more likely to have ILD and worse severity, compared to Jo-1 patients. Many medications have been efficacious for the treatment of IIM-associated ILD, including calcineurin inhibitors, rituximab, and cyclophosphamide. We suggest vigilant screening and monitoring of ILD in IIM patients with focus on the potential side effects associated with therapy and thus advocate appropriate vaccination, PCP prophylaxis, and bone health protection. Summary: Many different agents are used to manage patients with ILD with no comparative effectiveness studies to guide the clinician. The possibility of using MSAs to help guide treatment decisions is an appealing, although unproven, focus of research. Unfortunately, the rarity of non-Jo-1 myositis-specific antibodies has precluded robust study of response to treatment and overall management. Ongoing clinical trials and working groups are coordinating efforts to provide evidence-based management.
