Apheresis therapies include plasma exchange (PLEX) and immunoadsorption (IA), second line therapies to treat steroid unresponsive multiple sclerosis (MS) relapses that show a comparable response rate of 40 - 90%. Early active MS lesions can be classified into three main, intraindividually stable immunopathological patterns of demyelination (IP I-III), which suggests pathogenic heterogeneity and may also predict therapy response to PLEX/IA. A prior study of 19 patients showed that patients with an IP II, characterized by immunoglobulin and complement deposition, responded to PLEX treatment in contrast to patients with IPs I and III who had no treatment effects.

We aimed to evaluate the PLEX/IA response for MS relapses in relation to histopathologically defined IPs in a larger cohort of patients.

For this we retrospectively analyzed the efficacy of PLEX/IA in patients with early active demyelinating MS lesions histologicaly classified into IPs I-III. Primary outcome was a functional improvement of the neurological deficit occurring with the relapse. MRI and expanded disability status scale (EDSS) changes were used as secondary outcome parameters.

Clinical records of 69 patients were assessed. The highest response rate to PLEX/IA was 55% (22/40 patients) observed among IP II patients compared to no improvement found in patients with IP III (0/13; p

We confirmed that the therapy response to apheresis treatment is related to histopathologically defined IPs. Importantly, patients with both patterns I and II improved clinically after apheresis treatment; however, those patients with signs of a humoral immune response profited most from therapy. No clinical improvement was observed in patients with an IP III.
