Inclusion Criteria:

  • Age 18-80 years
  • Patients HTLV-1-associated myelopathy (tropical spastic paraparesis)

Exclusion Criteria:

  • Anticipated survival of at least 3 years
  • Inability to undergo neuroimaging with Magnetic Resonance

Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

No Intervention

Arm Label

Rituximab group

Control group

Arm Description

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

Patients will receive usual care and drug use.

Outcomes

Primary Outcome Measures

The improvement of pyramidal or bowel-bladder function score in EDSS during 12 month treatment
EDSS include the evaluated on visual, brainstem, pyramidal, cerebellar, sensory, bowel-bladder and cerebral functions

Secondary Outcome Measures

Change in immunology function
Use the flow cytometry to measure the change at baseline, 90,180, 360 days after drug use
