Introduction: In spite of its limited efficacy, cyclophosphamide (CYC) is frequently used to treat scleroderma-associated interstitial lung disease (SSc-ILD). The primary objective of this study was to evaluate changes in pulmonary function in SSc-ILD patients treated with CYC. Materials and Methods: 24 SSc-ILD outpatients from the Pneumonology Department of the Hospital de Clínicas in Buenos Aires, Argentina were studied retrospectively. Out of the 24 patients, 18 had extensive SSc-ILD, defined as disease extent on CT greater than 30% or FCV less than 70%; 12 of them were treated with CYC while the remaining 6 with limited disease did not receive treatment. Forced vital capacity (FVC) and carbon monoxide diffusing capacity (DLCO) data were collected both before and after treatment. Results: Among the 12 patients included, the FVC before and after the 9 month treatment was 2.25±0.51 (75.6±15.3% of the predicted value) and 2.14±0.50; (71.9±14.1%) (p: 0.17) respectively. In addition, a non-significant decrease in DLCO (ml/mmHg/min) was found after treatment (from 9.03 ±1.68 to 8.39 ± 1.31 (p: 0.29)). Conclusion: Although the 9 month treatment of extensive SSc-ILD with CYC did not show significant improvement, pulmonary function was stabilized.
