    Abstract

    Neuromyelitis optica is a severe demyelinating disease that selectively involves the optic nerves and the spinal cord but usually spares the brain. It is considered to have a B-cell-induced pathogenesis. Mitoxantrone hydrochloride, a synthetic anthracenedione approved for worsening relapsing-remitting multiple sclerosis and secondary progressive multiple sclerosis, has been shown to primarily suppress the humoral response.
    To evaluate the benefit of mitoxantrone treatment in patients with relapsing neuromyelitis optica.
    Prospective 2-year study.
    Academic multiple sclerosis center.
    Five patients (3 women and 2 men) with an age range of 20 to 51 years and an Expanded Disability Status Scale score of 2.5 to 6.5 (mean +/- SD, 4.40 +/- 1.88).
    Monthly intravenous infusions of mitoxantrone hydrochloride, 12 mg/m2, for 6 months followed by 3 additional treatments every 3 months.
    Expanded Disability Status Scale score measured every 3 months and during relapses; findings on orbital, brain, and spinal cord magnetic resonance images performed at baseline and at 3, 6, 12, 18, and 24 months; and visual evoked potentials and results of ophthalmologic evaluations performed at baseline and annually.
    During the 2 years of treatment, 2 patients each had a relapse once within the initial 5 months of treatment (1 severe and 1 moderate). Improvement was seen clinically and on magnetic resonance images in 4 patients. Patients generally tolerated the treatment well, although 1 patient had a reversible decrease in cardiac ejection fraction.
    Our results suggest a beneficial effect of mitoxantrone treatment for relapsing neuromyelitis optica.
