Background
Plasma exchange (PLEX) is a therapeutic option in the treatment of acute attacks of Demyelinating Diseases of the Central Nervous System (DDCNS). Factors related with PLEX response are not well established.
Methods
Descriptive and retrospective study. We included patients treated with PLEX for acute attacks of DDCNS between 2008 and 2017. We recorded demographics, clinical and treatment-related data, and Expanded Disability Status Scale (EDSS) score at admission, at discharge, and at 6 months.
Results
We included 64 patients. Forty-eight (75%) were female with a mean age of 48.28 ± 11.5 years. Half of our patients were diagnosed with multiple sclerosis. Clinical improvement was achieved in 51.6% at discharge and 62.5% at 6 months. The logistic regression model showed that EDSS score > 3 at admission (p = 0.04) and early clinical improvement with PLEX (p = 0.00) were predictors of good response to PLEX at discharge and at 6 months, respectively. No serious adverse effects were identified.
Conclusions
PLEX is a safe and effective treatment for acute attacks of DDCNS. EDSS score at admission and early clinical improvement with PLEX were factors associated with good response to PLEX.
