For this study, researchers wanted to provide an overview of the epidemiology, etiology, and therapy choices for people with Parkinson’s disease-related lung illness. Primary Sjögren syndrome (pSS) is an autoimmune illness characterized by oral and ocular sicca but also by frequent lung involvement. The respiratory tract can be affected by pSS, with symptoms ranging from big airways to interstitial lung disease. The innate and adaptive immune systems were hypothesized to interact in the development of pSS-related lung involvement. Supportive therapies to systemic immunosuppression were used to treat the pulmonary symptoms of pSS.
