Clinical Significance

A subset of interstitial lung disease (ILD) patients have underlying connective tissue diseases (CTDs). This panel serves as an aid for the diagnosis of CTDs, including rheumatoid arthritis, inflammatory myositis, systemic sclerosis, and Sjogren’s syndrome, that are associated with the development of ILD. If left untreated, these CTD patients may develop lung fibrosis and inflammation. ILD is a direct consequence of these pathological changes. When severe, ILD leads to restrictive lung disease, pulmonary arterial hypertension, and cardiac disease (cor pulmonale).
