Abstract

Lung involvement in systemic sclerosis. The objective of this study was to determine clinical predictors of interstitial lung disease in patients with systemic sclerosis (SSc) and pulmonary involvement as defined by presence of a decreased diffusing capacity for carbon monoxide (DLCO). Forty subjects with SSc were retrospectively evaluated. Patients were categorized according to their level of DLCO (< o ≥ 80% of predicted). Sensitivity of dyspnea to detect a decreased DLCO was 46.6% and specificity 90%, whereas oxygen desaturation showed a sensitivity of 71.4% and a specificity of 80%. Patients with decreased DLCO (n = 18) were not different in age (51.1 ± 13.5 vs. 53.5 ± 9.3 y, p = 0.5182), sex (male 13.6%, p = 0.6088), prevalence of Raynaud (86.6% vs. 85%, p = 0.6272), sicca syndrome (6.2% vs. 10.5% p = 1.0000) diffuse cutaneous involvement (94.1% vs. 83.3%, p = 0.6026) or esophageal dilatation. The duration of symptoms since diagnosis was no different. Prevalence of pulmonary ...
