Pulmonary Involvement in Scleroderma: A Clinical Study of the Safety and Efficacy of Mycophenolate Mofetil in Scleroderma Patients With Lung Involvement

Inclusion Criteria: * To participate in this study, patients must first undergo a BAL and HRCT. To be eligible to undergo HRCT and BAL (under the purview of this trial), prospective patients must meet the following criteria: * Aged 21-70. * Negative pregnancy test (with a sensitivity of at least 50 mIU/mL) for females of child-bearing potential * All patients must fulfill the criteria for SSc by American College of Rheumatology (ACR) criteria (Subcommittee for Scleroderma Criteria 1980). * FVC \< 85% of predicted. * SSc for no more than 7 years with onset defined as the date of the first non-Raynaud manifestation. * Patients may have limited (cutaneous thickening distal but not proximal to elbows and knees, with or without facial involvement) or diffuse (cutaneous thickening proximal to elbows and knees, often involving the chest or abdomen) cutaneous SSc (Medsger 1995). * Abnormal DLCO and abnormalities on the plain chest radiograph are not required, although a normal DLCO would be unusual in the face of significant ventilatory restriction due to SSc lung disease. * To be eligible to take study medication, the patient must meet not only the criteria above, but also must have ≥ 3.0% neutrophils or ≥ 2.0% eosinophils in screening BAL fluid and/or ground glass opacification on HRCT. * Women of childbearing potential should have a negative serum or urine pregnancy test with a sensitivity of at least 50 mIU/mL within 1 week before beginning therapy.
