Sjogren’s syndrome (SS) is a connective tissue disease targeting the exocrine glands with subsequent sicca symptoms mainly in eyes and mouth. Respiratory symptoms may be the most frequent extraglandular manifestation following fatigue and pain. Mucosal dysfunction may affect the upper and lower airways, being the small airways more frequently involved. Parenchymal disease carries most of the morbidity and mortality. Nonspecific interstitial pneumonia (NSIP) is the most common radiographic feature, whereas the fibrotic NSIP type is the most reported finding in biopsies. Pulmonary lymphoma may arise from bronchial-associated lymphoid tissue lesions, and although rare, it is prevalent in SS. Chronic hypertrophic bronchial wall changes may ascribe to the various cystic lesions. Under their presence, possible lymphocytic interstitial pneumonia, amyloidosis, and lymphoma should be explored. Pulmonary arterial hypertension may present as frequently as in lupus, especially in Asian populations. Advanced knowledge in the pathogenesis has helped in understanding the various presentations within the respiratory system, contrasting with the scarce therapeutic options to treat both the airway and parenchymal disease. Anti-fibrotic parenchymal lung therapy offers promising outcomes. The pulmonary involvement in SS may associate with a decline in quality of life and reduced life expectancy. Subsequently, clinicians should know these facts for a timely intervention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
