Severe restrictive lung disease in systemic sclerosis

Abstract

In SSc patients, black men with early disease who have cardiac involvement are the most likely to have factors associated with the development of severe restrictive lung disease (which is increasingly becoming a major cause of death). Disease subtype (diffuse versus limited cutaneous) and serum anti-topoisomerase I antibody do not differentiate between moderate and severe restrictive disease. Careful monitoring of pulmonary function early in the disease, when the greatest loss of lung function occurs, may help identify patients likely to respond to new therapy.
