Abstract
Sjögren's disease (SjD) is a chronic, progressive autoimmune condition of exocrine
and extraglandular tissues. It can present with isolated disease characterized by
lymphocytic infiltration of salivary or lacrimal glands, but in approximately one-third
of the patients, lymphocytic infiltration extends beyond exocrine glands to involve
extraglandular organs such as the lungs. Pulmonary complications have been reported
to occur between 9 and 27% of patients with SjD across studies. Respiratory manifestations
occur on a spectrum of severity and include airways disease, interstitial lung disease,
cystic lung disease, and lymphoma. Lung involvement can greatly affect patients' quality
of life, has a major impact on the overall prognosis, and frequently leads to alteration
in the treatment plans, highlighting the importance of maintaining a high index of
clinical suspicion and taking appropriate steps to facilitate early recognition and
intervention.
