Intravenous methylprednisolone versus therapeutic plasma exchange for treatment of anti-N-methyl-D-aspartate receptor antibody encephalitis: A retrospective review.
J Clin Apher. 2015 Aug; 30(4):212-6.JC

Abstract

INTRODUCTION

Anti-N-methyl-d-aspartate (NMDA) receptor antibody encephalitis is an increasingly recognized form of autoimmune encephalitis. Conventional treatments include therapies such as corticosteroids, intravenous immunoglobulin (IVIg), and/or therapeutic plasma exchange (TPE). Although TPE is regularly used for treatment of anti-NMDA receptor antibody encephalitis, the American Society for Apheresis has given it a category III recommendation only. Earlier administered immunotherapies in tumor-negative patients may facilitate faster recoveries, but it remains unclear whether or not TPE is superior to steroids and/or IVIG.

METHODS

We retrospectively evaluated 10 of 14 patients that received steroids and TPE with modified Rankin scores and subjectively assessed the point of largest sustained improvement in all 14 patients.

RESULTS

In the patients that received both steroids and TPE at our institution during the same hospitalization (only 10 of 14 patients), 7/10 patients after TPE had improved with the modified Rankin score versus 3/10 patients after steroids. The average modified Rankin score improvement after steroids in this group was -0.1 as compared with 0.4 after TPE. Based on subjective chart review analysis during which all 14 patients were assessed, the largest sustained improvement occurred immediately following the third-fifth exchange in 9/14 patients, whereas only 2/14 patients appeared to have had significant benefit immediately following steroids.

CONCLUSIONS

This is compelling preliminary data that suggests that corticosteroids may not be as effective compared to steroids followed by TPE. Given the importance of time-sensitive treatment, more formal studies may illuminate the ideal first-line treatment for anti-NMDA receptor antibody encephalitis.
