VZV meningitis

The varicella-zoster virus (VZV), a member of the Herpesviridae family, causes both the initial varicella infection and subsequent zoster episodes. Disorders of the eighth cranial nerve are common in people with herpes zoster oticus (HZO). We performed a review of the literature on different databases including PubMed and SCOPUS, focusing on cochlear and vestibular symptoms; 38 studies were considered in our review. A high percentage of cases of HZO provokes cochlear and vestibular symptoms, hearing loss and vertigo, whose onset is normally preceded by vesicles on the external ear...

A 36-year-old male with headaches was empirically treated for herpes simplex virus meningitis; CSF PCR testing later confirmed varicella zoster virus meningitis. Valacyclovir was increased to 2 g QID for remaining duration of therapy with full recovery. This case highlights the importance of comprehensive testing and proper treatment adjustment for rarer etiologies of aseptic meningitis.

Rapid identification of the causative pathogens of central nervous system infections is essential for providing appropriate management and improving patient outcomes. The performance of QIAstat-Dx Meningitis/Encephalitis (ME) Panel-a multiplex PCR testing platform-in detecting pathogens implicated in meningitis and/or encephalitis was evaluated using BioFire FilmArray ME Panel as a comparator method. This multicenter study analyzed 585 retrospective residual cerebrospinal fluid specimens and 367 contrived specimens...

Viral infections of the central nervous system (CNS) are common worldwide and result in considerable morbidity and mortality associated with neurologic illness. Until now, there have been no epidemiologic data regarding viruses causing aseptic meningitis, encephalitis, and CNS infections in Egypt. We investigated 1735 archived cerebrospinal fluid samples collected from Egyptian patients between 2016 and 2019 and performed molecular characterization for infection for12 different viruses: herpes simplex viruses 1 and 2 (HSV-1 and HSV-2), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), cytomegalovirus (CMV), human herpesviruses 6 and 7 (HHV-6 and HHV-7), human enteroviruses (HEVs), human parechovirus (HPeV), parvovirus B19 (B19V), adenovirus (AdV), and mumps virus (MuV)...

PURPOSE: We aimed to evaluate the performance of the FilmArray (FA) meningitis/encephalitis (ME) panel. Secondarily, we analyzed the false positive (FP) and false negative (FN) results, as well as the predictive values of the technique, regarding the cerebrospinal fluid (CSF) characteristics. METHODS: FA is a multiplex real-time PCR detecting 14 of the most common ME pathogens in CSF. All FA performed at our hospital (2018-2022) were retrospectively reviewed. FA was compared to conventional techniques and its performance was assessed based on the final diagnosis of the episode...

Clinical presentation of central nervous system (CNS) infections caused by varicella-zoster virus (VZV) is highly sophisticated, making identification challenging. We retrospectively reported 18 cases of VZV neurologic disease confirmed by metagenomic next-generation sequencing (mNGS). The detection rate of mNGS was higher than that of PCR assay (100 vs 66.7%, p < 0.05) and serum IgM antibody (100 vs 68.8%, p < 0.05) measurement. Of the 18 cases, five patients were diagnosed with acute meningitis, three with acute meningitis combined with facial neuritis, three with acute meningitis combined with polycranial neuritis, and the remaining seven with various clinical diagnoses...

Jugular foramen syndrome (JFS) is a lower cranial neuropathy syndrome characterized by dysphonia and dysphagia. The syndrome is caused by dysfunction of the glossopharyngeal, vagus, and spinal accessory nerves at the level of the pars nervosa and pars vascularis within the jugular foramen. There are numerous etiologies for JFS, including malignancy, trauma, vascular, and infection. Here, we present the case of a healthy adult man who developed JFS secondary to an atypical presentation of Varicella Zoster meningitis, and was promptly diagnosed and treated with rapid symptom resolution...

Varicella zoster virus (VZV) reactivation, also known as herpes zoster is common in older adults and immunocompromised individuals and often causes a painful, vesicular rash limited to a dermatomal distribution. On occasion, it can lead to various neurological complications as well. Here we present the case of a young, immunocompetent male in his 20's with a history of primary varicella infection who presented with complaints of a painful rash in the S3-S4 dermatomal distribution. Despite being initiated on the standard oral antiviral dose for two days, he developed a headache and neck stiffness...

AIM: We aimed to compare the clinical manifestation of HZ in immunocompetent and immunocompromised children. METHODS: Medical charts of all consecutive children hospitalized and/or consulted in the Regional Hospital for Infectious Diseases in Warsaw due to HZ were retrospectively analysed. Age, history of varicella, time interval between varicella and HZ, underlying diseases, immunosuppresive therapy, dermatome involvement and HZ complications were analyzed in both groups...

BACKGROUND Meningitis has been found to be associated with dementia. Different pathogens of meningitis lead to different cognitive impairments. However, the change of cognitive function and cellular metabolism in the hippocampus in varicella zoster virus (VZV) meningitis has received little attention. We aimed to explore the cognitive function and changes of cellular metabolism in bilateral hippocampal regions in VZV meningitis. MATERIAL AND METHODS We used magnetic resonance spectroscopy to check the cellular metabolism in the bilateral hippocampal region in 23 VZV meningitis patients and 19 controls in our hospital from June 2020 to November 2022...

PURPOSE OF REVIEW: The most common infectious etiologies of meningitis and encephalitis are viruses. In this review, we will discuss current epidemiology, prevention, diagnosis, and treatment of the most common causes of viral meningitis and encephalitis worldwide. RECENT FINDINGS: Viral meningitis and encephalitis are increasingly diagnosed as molecular diagnostic techniques and serologies have become more readily available worldwide but recent progress in novel antiviral therapies remains limited...

In this case report, we describe two unusual presentations of varicella-zoster virus (VZV) reactivation without rash, a condition known as Zoster Sine Herpete (ZSH). In Case 1, a 58-year-old woman presented with severe right-sided chest pain under her breast that radiated to the ipsilateral back. After the initial workup ruled out cardiac and musculoskeletal etiologies, the characteristic dermatomal distribution of pain made us suspect VZV reactivation. A diagnosis of ZSH was made with positive VZV IgG and IgM serologies and symptomatic relief after famciclovir treatment...

Central nervous system (CNS) infections such as meningitis and encephalitis are life-threatening conditions that demand hospital care and prompt identification of the causative agent. Since 2015, there has been only one CE-IVD-marked rapid multiplexed diagnostic assay in cassette format for bacterial and viral detection from cerebrospinal fluid (CSF): the BioFire FilmArray meningitis/encephalitis (ME) panel. In the beginning of 2022, Qiagen introduced the QIAstat-Dx meningitis/encephalitis panel. It is a CE-IVD-marked multiplex PCR cassette test intended for the identification of suspected infectious meningitis, encephalitis, or meningoencephalitis caused by bacterial, viral, or fungal pathogens...

RATIONALE: Meningoencephalomyelitis and visceral dissemination infection are rare but life-threatening complications of either the primary infection or reactivation of varicella-zoster virus (VZV) in immunocompromised patients. To date, few studies have reported the co-existence of VZV meningoencephalomyelitis and the visceral dissemination of VZV infection. PATIENT CONCERNS: A 23-year-old male was diagnosed with lupus nephritis class III and was being treated with oral prednisone and tacrolimus...

We present varicella-zoster virus (VZV) infection with concomitant lower cranial polyneuropathy in the absence of meningeal symptoms. Physical examination showed involvement of cranial nerves IX and X in Case 1 and of cranial nerves IX, X, and XI in Case 2. Cerebrospinal fluid (CSF) analysis revealed mild lymphocytic pleocytosis, normal protein levels, and absence of VZV-DNA based on polymerase chain reaction (PCR) analysis. Serum anti-VZV antibody testing showed positive results in both cases, which confirmed the diagnosis of VZV infection...

Point-of-care syndromic PCR (POC SPCR) assays are useful tools for the rapid detection of the most common causative agents of community-acquired infections responsible for meningitis and encephalitis infections. We evaluated the performance characteristics of the new QIAstat-Dx® Meningitis/Encephalitis panel (QS) compared to the laboratory reference methods and the POC SPCR Biofire® FilmArray® Meningitis Encephalitis Panel (FA). Viral (Enterovirus, Parechovirus, HSV-1, HSV-2, HHV-6, VZV) and bacterial ( E...

Clinical features applicable to the entire spectrum of viral meningitis are limited, and prognostic factors for adverse outcomes are undetermined. This nationwide population-based prospective cohort study included all adults with presumed and microbiologically confirmed viral meningitis in Denmark from 2015 until 2020. Prognostic factors for an unfavourable outcome (Glasgow Outcome Scale score of 1-4) 30 days after discharge were examined by modified Poisson regression. In total, 1066 episodes of viral meningitis were included, yielding a mean annual incidence of 4...

OBJECTIVES: This study aimed to investigate the immune changes in patients with varicella-zoster virus (VZV) encephalitis/meningitis and explored their relationships with prognosis. METHODS: A total of 129 patients with herpes zoster (HZ), 32 patients with VZV encephalitis/meningitis and 31 non-HZ and non-VZV people as healthy controls were included into the present study. The numbers of peripheral T lymphocytes and the serum levels of complements 3 (C3), complements 4 (C4) and immunoglobulin A (IgA), immunoglobulin G (IgG), and immunoglobulin M (IgM) were detected and compared among groups...

Acute neurologic complications from Varicella-Zoster-Virus reactivation occur in both immunocompromised and immunocompetent patients. In this report, we describe a case of a previously healthy immunocompetent boy who had received two doses of varicella vaccine at 1 and 4 years. At the age of 12 he developed acute aseptic meningitis caused by vaccine-type varicella-zoster-virus without concomitant skin eruptions. VZV-vaccine strain DNA was detected in the cerebrospinal fluid. The patient made a full recovery after receiving intravenous acyclovir therapy...
