niman Posted March 10, 2016 Author Report Share Posted March 10, 2016 To the Editor:Zika virus (ZIKV) is currently spreading widely, while its clinical spectrum remains a matter of investigation. Evidence of a relationship between ZIKV infection and cerebral birth abnormalities1,2is growing.3 An increased incidence of some peripheral nervous syndromes among adults was reported during outbreaks in French Polynesia4,5 and Brazil,1,2 but no formal link with ZIKV infection was shown. We describe a case of central nervous system infection with ZIKV that was associated with meningoencephalitis in an adult.An 81-year-old man was admitted to the intensive care unit (ICU) 10 days after he had been on a 4-week cruise in the area of New Caledonia, Vanuatu, the Solomon Islands, and New Zealand; he was reported to have been in perfect health during that time. On medical examination, he was febrile (39.1°C) and comatose (Glasgow Coma Scale score of 6 on a scale from 3 to 15, with lower scores indicating a reduced level of consciousness) with hemiplegia of the left side, paresis of the right upper limb, a normal response to tendon reflexes, and a Babinski sign on the left side. The patient’s trachea was intubated and mechanical ventilation begun; a transient rash was observed within the next 48 hours.Magnetic resonance imaging (MRI) of the brain was suggestive of meningoencephalitis. There were asymmetric subcortical white-matter hyperintensities on fluid-attenuated inversion recovery (FLAIR) imaging, multiple punctuated hyperintensities on diffusion-weighted sequences that were evocative of ischemic foci, and a slight hyperintensity of the right rolandic fissure that was evocative of meningitis (Figure 1FIGURE 1Imaging of the Brain.). Computed tomographic angiography revealed an irregular narrowing of the right callosomarginal artery.A lumbar puncture was performed on day 1, and findings on analysis of cerebrospinal fluid (CSF) were suggestive of meningitis: the leukocyte count was 41 per cubic millimeter (with 98% polymorphonuclear leukocytes), the protein level was 76 mg per deciliter, and the ratio of CSF to blood glucose was 0.75. The patient was initially treated with amoxicillin, cefotaxime, gentamicin, and acyclovir, but these antimicrobial agents were stopped on day 5. Investigations in both CSF and blood for other infections were unrevealing (see the Supplementary Appendix, available with the full text of this letter at NEJM.org), except for a positive result for ZIKV on reverse-transcriptase–polymerase-chain-reaction assay of the CSF (cycle threshold, 34). ZIKV was grown in culture from the CSF on a Vero cell line (see the Supplementary Appendix). These findings all support the diagnosis of ZIKV-associated meningoencephalitis.Several electroencephalograms showed no direct signs that were suggestive of epilepsy during levetiracetam therapy (which was administered for the first time in the ICU because seizure had been suspected as one of the mechanisms of the initial consciousness disorder). Spontaneous arousal occurred within 24 hours after intubation, and mechanical ventilation was weaned on day 2. At that time, the patient was awake but had spatial delusion with visual and kinesthetic hallucinations and a persisting weakness (2/5) of the left arm. His neurologic condition continued to improve without specific treatment. He was discharged from the ICU on day 17, and his cognitive function was fully recovered by day 38. He had a residual weakness (4/5) of the left arm. Clinicians should be aware that ZIKV may be associated with meningoencephalitis. Link to comment Share on other sites More sharing options...
