OBJECTIVES: The benefits of plasmapheresis (PA) for neurologic autoimmune diseases have been widely demonstrated. Little is known about the long-term neurologic prognosis and course after PA and immunosuppressive (IS) and/or intravenous immunoglobulin (IVIG) treatment. We aimed to analyse features associated with short-term response and long-term outcome and prognosis (neurologic status and mortality) of peripheral polyneuropathy (PP) and central nervous system acute inflammatory disease (CNSAID) treated with PA.
PATIENTS AND METHODS: A descriptive, retrospective single-centre study from January 2005 to December 2012.
RESULTS: There were 26 episodes, which included 16 CNSAID and 10 PP cases. First line therapy included PA (n=4), IS drugs (n=15), and IVIG (n=7). Responses were achieved in 80% and 50% of PP and CNSAID cases, respectively. For PP, first line treatment with IVIG and no IS treatment prior to or during PA were variables associated with short-term response (P=0.067), good or stable neurologic status at the end of follow-up (P=0.008), and lower mortality rate (P=0.008). For CNSAID, initial EDSS score≥7 (P=0.019) was related to long-term good or stable neurologic status. During the study period, 177 sessions were conducted; 3.4% had technical complications and 8.5% clinical complications. However, these incidents were all minor and no PA session had to be discontinued.
CONCLUSION: The response rates achieved in our patients were similar to those of other research. PA has a safe profile but double-blind, controlled studies are needed to evaluate the synergy of sequential treatment with IGIV followed by PA and the possible benefit for long-term outcome.
