Fibrosing alveolitis in systemic sclerosis: Indices of lung function in relation to extent of disease on computed tomography

Abstract

The percent predicted DLCO best reflects the extent of fibrosing alveolitis in FASSc, and therefore should be measured in routine evaluations. Exercise testing may also have a useful role in staging the severity of pulmonary fibrosis, but the CRP index offers no additional advantage over the DLCO and exercise testing.
