We aimed to evaluate the value of immunoadsorption (IA) treatment after the failure of intravenous methylprednisolone (IVMP) therapy for neuromyelitis optica spectrum disorder (NMOSD). Sixty-one NMOSD attacks unresponsive to IVMP were included: 22 patients received rescue IA (IVMP+IA), 24 underwent rescue plasma exchange (PE) (IVMP+PE), and 21 received no further rescue therapy (IVMP alone). The improvement frequencies were higher in the IVMP+IA and IVMP+PE groups than in the IVMP-alone group (P = 0.024). The effective period for IA treatment may be longer than previously thought. IA treatment for IVMP-resistant NMOSD attacks was effective and comparable to PE treatment. [Display omitted] •IA treatment for IVMP-resistant NMOSD attacks was effective and comparable to PE treatment.•The efficacy of rescue IA seemed superior to that of rescue PE for the MY subtype of NMOSD attacks.•The effective period for IA treatment may be longer than that previously thought.
