HTLV-1-associated Myelopathy
Conditions
Brief summary
Neuroprotective or anti-inflammatory strategies are invaluable in HTLV-1-associated myelopathy due to its rapid progression. We evaluated the efficacy of rituximab in patients with HTLV-1-associated myelopathy.
Interventions
A lower dosage of rituximab for HTLV-1-associated myelopathy
Sponsors
Study design
Intervention model description
Experimental: Rituximab group Drug: Rituximab will be administered as 100 mg IV, once per week for 3 consecutive weeks. Continued dosage was dependent on the percentage of circulating CD19 B-cell counts from patients . Whenever it reached 1% of total lymphocyte population, rituximab 100 mg was reinfused Placebo Comparator: Control group Patients will receive usual care and drug use.
