Detection and Management of Autoimmune Disease-Associated Interstitial Lung Diseases

Interstitial lung disease (ILD) causes significant morbidity and mortality patients with systemic autoimmune rheumatic diseases. Patients at high risk of ILD should be screened using high-resolution CT (HRCT), but there is no consensus as to which risk factors-or combination of risk factors- should prompt referral for HRCT. The course of autoimmune disease- associated ILD is highlyvariable, and it may not mirror the activity of the underlying autoimmune disease. Patients require close monitoring with periodic pulmonary function testing and symptom assessment and with repeat HRCT considered based on clinical assessment. The relevance of clinical and radiologic signs of progression-and their implications for management-ideally should be discussed by a multidisciplinary team. Management of autoimmune disease-associated ILD may involve immunosuppressant and/or antifibrotic therapy in addition to supportive care. It is important that treatment decisions be individualized to the needs and wishes of the patient. Regular follow-up is important to monitor disease progression and manage the adverse effects related to treatment.
