A Case Report of Varicella Zoster Meningitis as Co-Infection With Breakthrough COVID-19 in an Immunocompetent Patient.

There are several previous reports that infection or reactivation of varicella zoster virus (VZV) can occur after coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Herein, we report a rare case of VZV meningitis in breakthrough COVID-19. An 18-years-old male visited the emergency room, presenting with a headache and fever of up to 38.4°C for 5 days. He received the second dose of BNT162b2 mRNA SARS-CoV-2 vaccine 7 weeks prior to symptom onset. The symptoms persisted with headache, fever, and nausea. His cerebrospinal fluid (CSF) showed an elevated opening pressure of 27 cm H2O, 6/µL red blood cells, 234/µL white blood cells (polymorphonuclear leukocytes 3%, lymphocytes 83%, and other 14%), 43.9 mg/dL protein, and 59 mg/dL glucose, and CSF polymerase chain reaction (PCR) test was positive for VZV. Also, he was diagnosed with COVID-19 by reverse transcriptase-PCR examining upper and lower respiratory tract. We administered intravenous acyclovir for 12 days, and he was discharged without any neurologic complication.

COVID-19 meningitis without pulmonary involvement with positive cerebrospinal fluid PCR.

BACKGROUND: Coronavirus disease 2019 (COVID-19) typically presents with respiratory illness ranging in severity. Neurological complications of the disease remain largely unknown. Herein, we discuss the case of a woman diagnosed with COVID-19 meningitis following two positive cerebrospinal fluid (CSF) RT-PCR assays, and highlight the importance of recognizing the neurological manifestations of the disease. CASE REPORT: The patient was a 49-year-old woman with a history of hypertension who presented with non-specific symptoms (fever, headache, malaise, nausea/vomiting). Chest computed tomography (CT) revealed a lack of pulmonary involvement and oropharyngeal/nasopharyngeal RT-PCR was negative for COVID-19. A lumbar puncture was performed on the third day of admission and the CSF analysis elucidated a viral pattern, but the CSF bacterial culture and RT-PCR assay for herpes simplex virus were both negative. Surprisingly, the CSF RT-PCR for COVID-19 was positive. The diagnosis of COVID-19 meningitis was made and the patient was treated solely with Kaletra® , with a second CSF analysis confirming our unique finding 1 week later. The patient's clinical characteristics improved progressively, and she was discharged in excellent general condition after 21 days. CONCLUSION: In contrast to what was originally believed, the SARS-CoV-2 can cause meningitis in isolation, perhaps by crossing the blood-brain barrier. Hence, it seems essential that physicians maintain a high index of suspicion for neurological involvement among COVID-19 patients, with early CSF analysis and brain imaging sometimes being indicated.

COVID-19: A Global Threat to the Nervous System.

In less than 6 months, the severe acute respiratory syndrome-coronavirus type 2 (SARS-CoV-2) has spread worldwide infecting nearly 6 million people and killing over 350,000. Initially thought to be restricted to the respiratory system, we now understand that coronavirus disease 2019 (COVID-19) also involves multiple other organs, including the central and peripheral nervous system. The number of recognized neurologic manifestations of SARS-CoV-2 infection is rapidly accumulating. These may result from a variety of mechanisms, including virus-induced hyperinflammatory and hypercoagulable states, direct virus infection of the central nervous system (CNS), and postinfectious immune mediated processes. Example of COVID-19 CNS disease include encephalopathy, encephalitis, acute disseminated encephalomyelitis, meningitis, ischemic and hemorrhagic stroke, venous sinus thrombosis, and endothelialitis. In the peripheral nervous system, COVID-19 is associated with dysfunction of smell and taste, muscle injury, the Guillain-Barre syndrome, and its variants. Due to its worldwide distribution and multifactorial pathogenic mechanisms, COVID-19 poses a global threat to the entire nervous system. Although our understanding of SARS-CoV-2 neuropathogenesis is still incomplete and our knowledge is evolving rapidly, we hope that this review will provide a useful framework and help neurologists in understanding the many neurologic facets of COVID-19.
