Cytoxan for scleroderma – pro

Immunosuppressive agents such as cyclophosphamide have long been used to treat autoimmune disease, but the dose is often limited by bone marrow suppression. In a randomized placebo-controlled trial, those with scleroderma-related alveolitis and interstitial lung disease who received Cytoxan for one year had better forced vital capacity than patients on placebo, a difference still seen at two-year follow-up. In addition, patients who had taken Cytoxan had modest improvement of dyspnea, skin thickening, functional ability, and some health-related quality-of-life measures. In an accompanying NEJM editorial, Fernando J. Martinez, M.D., and W. Joseph McCune, M.D., of the University of Michigan Health System in Ann Arbor, commented that “this well-designed trial will be regarded as a sentinel study confirming a beneficial response to cyclophosphamide in highly selected patients with scleroderma-related interstitial lung disease.”
