Systemic sclerosis with associated interstitial lung disease: management considerations and future directions

Abstract

Systemic sclerosis (SSc), also referred to as scleroderma, is a rare autoimmune disease associated with vasculopathy, inflammation, and fibrosis of the skin and/or internal organs. Interstitial lung disease (ILD) is a frequent complication and is the leading cause of death in patients with SSc. Although economic data are limited, available data suggest that SSc-ILD is associated with significant cost implications. Treatment of SSc-ILD has historically been with immunosuppressive agents. In 2019, however, the treatment landscape expanded with the FDA approval of the tyrosine kinase inhibitor nintedanib. A lack of codified treatment guidelines for patients with SSc-ILD creates significant challenges in improving outcomes at the patient level and, more generally, in reducing disease burden to the health care system. As the treatment landscape continues to evolve, it is likely that to reduce lung volume loss in patients, a combination of immunosuppressive and antifibrotic approaches will need to be used. Additionally, a greater emphasis on risk-stratification strategies may allow for more efficient follow-up, monitoring, and assessment of treatment response.
