Funn av varicella-zoster virus DNA ved medullære og hjernestammeattakker hos MS pasienter

Hensikten med studien er å beskrive tre pasienter med medullære eller hjernestamme MS-lesjoner og varicella-zoster virus DNA i ryggmargsveske. Forskningen utgår fra Haukeland Universitetssykehus.

We describe three cases of patients with concomitant acute medullary or brainstem multiple sclerosis (MS) lesions and detectable spinal fluid varicella-zoster virus DNA. Herpes simplex virus PCR was also positive in two of the patients. One patient was re-punctured 2 weeks following the relapse, with negative results. The PCR findings greatly delayed correct diagnosis and treatment in all three patients. Based on our cases, we propose that inflammatory medullary and brainstem lesions could result in viral leakage, and possibly viral reactivation, from destroyed sensory neurons, yielding false-positive cerebrospinal fluid PCR results. As this can have diagnostic and therapeutic consequences, further studies are warranted to evaluate the clinical relevance of these findings.
