Epub ahead of print: Kwiatkowski et al. Herpes encephalitis during natalizumab treatment in multiple sclerosis. Mult Scler. 2011 Nov 2.
In this case report the authors describe a case of non-fatal herpes simplex virus encephalitis (HSE) in a subject on natalizumab for MS. A 36-year-old woman, previously treated with immunomodulatory and immunosuppressive drugs for MS, developed acute encephalitis after 6 monthly natalizumab infusions. Brain imaging demonstrated bi-temporal lesions typical of HSE. Herpes simplex virus type-1 DNA was detected in cerebrospinal fluid (diagnostic test). The patient improved gradually after a 21-day course of intravenous acyclovir, but neuropsychiatric changes remained 5 months later (poor prognosis). This non-fatal case of HSE and other reported cases of herpes infections provide evidence of an increased risk with natalizumab and point to the need for clinicians to maintain awareness.
