Mycophenolate mofetil in primary central nervous system vasculitis

ObjectiveTo evaluate the efficacy and safety of mycophenolate mofetil (MMF) in adult primary central nervous system vasculitis (PCNSV).MethodsWe studied a cohort of 163 patients with PCNSV who were seen at the Mayo Clinic from 1983 to 2011. We compared patients treated with MMF and those receiving other therapies.ResultsWe identified 16 patients treated with MMF. MMF in combination with GCs achieved a favorable response in most patients. A significant proportion of patients treated with MMF had a less severe disability at last follow-up compared to those receiving other therapies (p = 0.023) and cyclophosphamide and prednisone (p = 0.017). No statistically significant differences were observed regarding relapses and ability to discontinue therapy at last follow-up. A trend to a more favorable treatment response was observed in patients treated with MMF compared to those treated with other therapies (p = 0.075). Only 1 patient suspended MMF for severe leukopenia.ConclusionMMF seems to be an effective and safe therapy for adult PCNSV.
