RESUMO
INTRODUCTION: Cyclophosphamide (CPM) is used empirically in the treatment of progressive multiple sclerosis. The purpose of this study was to evaluate its efficacy in naive patients with progressive multiple sclerosis. PATIENTS AND METHODS: Thirty-one patients were retrospectively included (17 secondary multiple sclerosis, 14 primary progressive multiple sclerosis), and received infusions of CPM (600mg/m(2)) every eight weeks, for 18 months. Evaluation was based on time to EDSS progress. RESULTS: Among patients with secondary progressive multiple sclerosis, 94% were stable or improved at six months, 77% at 12 months, and 75% at 18 months. The same result was reported in 69.2% of primary progressive multiple sclerosis at six months, 64% at 12 months, and 55.5% at 18 months. We found no difference between the two groups. CONCLUSION: Our results suggest that the CPM is efficient in progressive multiple sclerosis; however, its place must be reconsidered before establishing an international consensus for treatment; open label studies are needed to validate the present findings.
