Outcomes
Primary Outcome Measures
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>
Secondary Outcome Measures
Change in ALSFRS-R decline
Change in ALSFRS-R decline before (3-month) and after (6-month) intervention
Changes in ALSFRS-R score
Changes in ALSFRS-R score from day 0 to days 30, 90, and 180
Change in force vital capacity
Change in force vital capacity before intervention and on day 90
Change in compound motor action potentials
Change in compound motor action potentials before intervention and on day 90
Changes in anti-NRIP titer
Changes in anti-NRIP titer from day 0 to days 30, 90, and 180
Any adverse effect under plasmapheresis
Any adverse effect during and within 6 months after plasmapheresis
