Interstitial lung disease is the major cause of death in patients with systemic sclerosis (scleroderma) (1). Pathologic studies of early disease show inflammation in the pulmonary interstitium that spills into alveolar spaces (2). Bronchoalveolar lavage fluid obtained from patients with scleroderma who have lung inflammation (alveolitis) may contain increased numbers of total cells, T cells, neutrophils, eosinophils, and mast cells (37). Alveolitis has been associated with subsequent deterioration of pulmonary function in scleroderma (34).

Survival in patients with scleroderma and alveolitis.dashed linesolid lineP

Survival was better among patients with alveolitis who received cyclophosphamide ( ) than among patients with alveolitis who were not treated ( ) ( = 0.01, Cox–Mantel log-rank test). The numbers above the lines are the number of patients at risk at the indicated time point. The median survival rate was 89% (25th, 75th percentiles, 84%, 94%) in treated patients and 71% (25th, 75th percentiles, 55%, 86%) in untreated patients.

Results of pulmonary function tests done at the time of bronchoalveolar lavage or lung biopsy were compared with those of the last tests done in a patient. “Treated” indicates patients with alveolitis who received cyclophosphamide, and “untreated” indicates patients with alveolitis who did not receive cyclophosphamide. The line in the middle of each box shows the 50th percentile, the limits of the box show the 25th and 75th percentiles, and the limits of the bar show the 5th and 95th percentiles.
