Outcome Measures

Primary Outcomes (1)

  • Change in ALSFRS-R decline

    Change in ALSFRS-R decline before (3-month) and after (3-month) intervention. \<ALSFRS-R indicates revised ALS functional rating scale, ranged from 0 to 48 with the higher, the better motor function\>

    Before (3-month) and after (3-month) intervention

Secondary Outcomes (6)

  • Change in ALSFRS-R decline

    Before (3-month) and after (6-month) intervention

  • Changes in ALSFRS-R score

    Day 0 to days 30, 90, and 180

  • Change in force vital capacity

    Before intervention and on day 90

  • Change in compound motor action potentials

    Before intervention and on day 90

  • Changes in anti-NRIP titer

    Day 0 to days 30, 90, and 180

  • +1 more secondary outcomes

Study Arms (1)

ALS patients receiving plasmapheresis

OTHER

Plasmapheresis in ALS patients with different titers of autoantibody against NRIP

Procedure: Plasmapheresis

Interventions

Regular plasmapheresis to remove anti-NRIP autoantibody

ALS patients receiving plasmapheresis
