Risk factors for primary Sjögren syndrome-associated interstitial lung disease

摘要

BackgroundPrimary Sjögren syndrome (pSS) is a chronic inflammatory autoimmune disease that is characterized by lymphocytic infiltration of the exocrine glands and extraglandular organ systems. Interstitial lung disease (ILD) is common in pSS patients and is one of the independent risk factors for a poor prognosis. The previously reported characteristics and potential risks contributing to pSS-associated ILD have been controversial.
