Abstract
Connective tissue diseases (CTD) comprise a group of autoimmune diseases that can
affect multiple organs in the body including the lungs. The most common form of pulmonary
involvement is interstitial lung disease (ILD). CTD-associated ILD (CTD-ILD) can take
one of several courses including nonprogressive, chronically progressive, or rapidly
progressive. Chronically and rapidly progressive patterns are associated with increased
mortality. Limited randomized controlled trial data are available for treatment of
CTD-ILD, with most data coming from systemic sclerosis-related ILD. The current first-line
treatment for all CTD-ILD is immunosuppression with consideration of antifibrotics,
stem cell transplant, and lung transplant in progressive disease. In this article,
we review data for ILD treatment options in systemic sclerosis, rheumatoid arthritis,
myositis, and primary Sjögren's syndrome-related ILDs.
