Varicella-zoster virus-related neurological complications: From infection to immunomodulatory therapies. Rev Med Virol 2024; 34:e2554. [PMID: 38862398 DOI: 10.1002/rmv.2554] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Revised: 05/11/2024] [Accepted: 05/27/2024] [Indexed: 06/13/2024]
Abstract
The Varicella-zoster virus (VZV), classified as a neurotropic member of the Herpesviridae family, exhibits a characteristic pathogenicity, predominantly inducing varicella, commonly known as chickenpox, during the initial infectious phase, and triggering the reactivation of herpes zoster, more commonly recognized as shingles, following its emergence from a latent state. The pathogenesis of VZV-associated neuroinflammation involves a complex interplay between viral replication within sensory ganglia and immune-mediated responses that contribute to tissue damage and dysfunction. Upon primary infection, VZV gains access to sensory ganglia, establishing latent infection within neurons. During reactivation, the virus can spread along sensory nerves, triggering a cascade of inflammatory mediators, chemokines, and immune cell infiltration in the affected neural tissues. The role of both adaptive and innate immune reactions, including the contributions of T and B cells, macrophages, and dendritic cells, in orchestrating the immune-mediated damage in the central nervous system is elucidated. Furthermore, the aberrant activation of the natural defence mechanism, characterised by the dysregulated production of immunomodulatory proteins and chemokines, has been implicated in the pathogenesis of VZV-induced neurological disorders, such as encephalitis, myelitis, and vasculopathy. The intricate balance between protective and detrimental immune responses in the context of VZV infection emphasises the necessity for an exhaustive comprehension of the immunopathogenic mechanisms propelling neuroinflammatory processes. Despite the availability of vaccines and antiviral therapies, VZV-related neurological complications remain a significant concern, particularly in immunocompromised individuals and the elderly. Elucidating these mechanisms might facilitate the emergence of innovative immunomodulatory strategies and targeted therapies aimed at mitigating VZV-induced neuroinflammatory damage and improving clinical outcomes. This comprehensive understanding enhances our grasp of viral pathogenesis and holds promise for pioneering therapeutic strategies designed to mitigate the neurological ramifications of VZV infections.

Fan HR, Zhang EM, Fei Y, Huang B, Yao M. Early Diagnosis of Herpes Zoster Neuralgia: A Narrative Review. Pain Ther 2023; 12:893-901. [PMID: 37129752 PMCID: PMC10289968 DOI: 10.1007/s40122-023-00510-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Accepted: 03/30/2023] [Indexed: 05/03/2023] Open
Abstract
BACKGROUND Early intervention reduces the incidence of postherpetic neuralgia (PHN). Typical shingles are easy to diagnose; however, there is no clear diagnostic method for neuralgia symptoms manifested before the onset of the rash, which can easily cause misdiagnosis. This not only increases the patient's pain, medical expenses, and mental burden, but more importantly, delays the valuable time for early treatment of shingles, and increases the probability of complications and PHN. OBJECTIVE In this paper, the diagnostic methods of preherpetic neuralgia were summarized and analyzed, and the current challenges were put forward to provide directions for the early diagnosis of herpes zoster (HZ) in the future. METHODS PubMed, and China National Knowledge Infrastructure (CNKI) libraries were searched using the terms "herpes zoster," "before the blistering," "diagnosis," and "neuralgia." Clinical trials, reviews, and case reports were collected and reviewed. The period of literature search is from 1 January 1980 to 1 October 2022. RESULTS The early diagnosis of herpes zoster neuralgia can reduce misdiagnosis and mistreatment, and timely and effective intervention can significantly reduce the incidence of PHN. The body may possess a mechanism that limits the local breakthrough of the virus in the skin, causing blistering later than the onset of pain. Changes in the plasma proteins of patients with varicella-zoster virus shingles neuralgia may be used as an early diagnostic indicator in patients with HZ neuralgia before eruption. CONCLUSION Early diagnosis of HZ neuralgia before eruption can facilitate timely targeted treatment, thereby reducing the incidence of PHN. Proteomic quantitative analysis and validation results can serve as a simple, micro, rapid, and accurate diagnostic method.

Abstract
Clinical reactivations of herpes simplex virus or varicella zoster virus occur frequently among patients with malignancies and manifest particularly as herpes simplex stomatitis in patients with acute leukaemia treated with intensive chemotherapy and as herpes zoster in patients with lymphoma or multiple myeloma. In recent years, knowledge on reactivation rates and clinical manifestations has increased for conventional chemotherapeutics as well as for many new antineoplastic agents. This guideline summarizes current evidence on herpesvirus reactivation in patients with solid tumours and hematological malignancies not undergoing allogeneic or autologous hematopoietic stem cell transplantation or other cellular therapy including diagnostic, prophylactic, and therapeutic aspects. Particularly, strategies of risk adapted pharmacological prophylaxis and vaccination are outlined for different patient groups. This guideline updates the guidelines of the Infectious Diseases Working Party (AGIHO) of the German Society for Hematology and Medical Oncology (DGHO) from 2015 "Antiviral prophylaxis in patients with solid tumours and haematological malignancies" focusing on herpes simplex virus and varicella zoster virus.

Abstract
The incidence of syphilis has increasing recently, largely attributable to improved screening that may result in the diagnosis of chronic untreated infections. These patients can develop severe or subtle neurologic symptoms that can be missed and, therefore, detected accidentally while a patient is evaluated for other mimicking neurological infections. A 58-year-old man with diabetes presented with 2 days of aphasia, headache, chills and confusion. He had an MRI brain with evidence of a prior cerebrovascular accident. Subsequently, he developed a fever and thoracic dermatomal rash consistent with herpes zoster. A lumbar puncture was performed, and cerebrospinal fluid analysis revealed a lymphocytic pleocytosis, a reactive Venereal Disease Research Laboratory test and positive varicella-zoster virus (VZV) PCR. He was suspected to have both late neurosyphilis and acute meningoencephalitis from VZV. This paper will discuss how to approach the diagnosis of late neurosyphilis and possible associations with herpesvirus central nervous system infections.

Abstract
A prospective study was conducted to compare metagenomic next-generation sequencing (mNGS) and conventional testing in investigating the pathogens of central nervous system (CNS) infections in allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients. A total of 53 patients with CNS disorders after allo-HSCT were enrolled in this study. A total of 35 patients were diagnosed as CNS infections, including 28 viral, 2 bacterial, 1 fungal, 3 mixed infections, and 1 infection with unknown pathogen. Among these 35 patients with CNS infections, mNGS identified 5 patients who were not identified by conventional testing. For the remaining 30 infections, mNGS made concurrent diagnoses with conventional testing in 29, while 1 was diagnosed according to the good response to the antimicrobial treatment without etiological evidence. The presence of Aspergillus detected by mNGS only in one patient was considered false positive due to lack of validation. The sensitivity of mNGS and conventional testing for diagnosing CNS infections post transplant were 97.1% and 82.9%, respectively (P = 0.106), while the specificity of mNGS and conventional testing were 94.4% and 100%, respectively (P = 1.000). These results suggest that mNGS might be a promising technology for diagnosis of CNS infections post transplant. Viruses were the most common pathogens of CNS infections in allo-HSCT recipients.

[PMID: 32571239 PMCID: PMC7309994 DOI: 10.1186/s12879-020-05155-8] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2020] [Accepted: 06/12/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The aseptic meningitis caused by varicella zoster virus (VZV) reactivation was less described in the literature, most of which were detected by means of polymerase chain reaction. The authors presented 4 adult immunocompetent patients with acute aseptic meningitis with VZV infection diagnosed by next-generation sequencing (NGS). CASE PRESENTATION Four patients were admitted to the hospital with headache and fever between March 2018 and August 2019. The median ages were 37 years (range 22-52 years). The median symptoms onset to clinic time was 3.5 days (range 3-6 days). Two patients had signs of meningeal irritation. Rash occurred after the meningitis symptoms in 1 patient (time from meningitis symptoms to rash, 2 days). No other sign or symptom was reported. The brain Magnetic resonance imaging and electroencephalography were normal in all patients. Cerebrospinal fluid (CSF) samples were obtained at a median of 4 days (range 3-7 days) from the meningitis symptoms onset. Opening pressure of lumbar puncture after admission were high in these cases (median 256 mm H2O; range 165-400 mm H2O). White blood cell counts and protein levels were significantly elevated in CSF samples (median 317 × 10^6/L, range 147-478 × 10^6/L; median 1.41 g/L, range 0.57-1.79 g/L). The cytology of CSF demonstrated a lymphocytic pleocytosis, and most multinuclear cells. The culture of CSF was negative for all 4 cases, while T-cell spot test was positive for 2 cases, who were administrated with anti-tuberculosis treatment for suspicious tuberculous meningitis. NGS of CSF (the Vision Medical Research Institute) detected specific sequences of VZV in the 4 cases within 72 h after admission. The inappropriate treatment were stopped while acyclovir were continued intravenously for 10-14 days. All patients recovered completely. CONCLUSIONS VZV is an infectious agent that causes aseptic meningitis in immunocompetent adults and could not be accompanied by skin manifestations. The NGS of CSF is a rapid detection for the identification and differentiation of meningitis in patients, which is of great importance for providing the rapid and accurate diagnosis and the targeted antimicrobial therapy for central nervous system infection.

Abstract
Previous research indicates that infection, especially from viruses in the family Herpesviridae, may play a role in the etiology of some cases of autism spectrum disorder (ASD). Using a case-control design and the polymerase chain reaction with site-specific primers, we screened newborn and childhood blood samples for the presence of eight human herpesviruses. Herpesvirus DNA was detected in 4 of 225 ASD individuals and 2 of 235 controls, with the most frequently detected virus being HHV-6B. Although this study does not detect a significant ASD-Herpesviridae association, it is limited by the use of site-specific primers. We suggest that new techniques using bioinformatics to search next-generation sequencing databases will be more revealing of possible ASD-virus associations.

Abstract
Varicella zoster virus reactivation is a rare cause of pharyngeal dysphagia with long-term sequelae persisting in most cases. A 76-year-old immunocompetent woman presented with a 4-week history of dysphagia and dysphonia. Brain magnetic resonance imaging displayed a negative finding. Fiberoptic endoscopic evaluation of swallowing showed a severe dysphagia leading to a percutaneous gastrostomy eventually. Cerebrospinal fluid analysis revealed a lymphocytic pleocytosis and polymerase chain reaction amplified Varicella zoster virus DNA. Eight months after Acyclovir treatment and despite a persisting impairment of the recurrent laryngeal nerve, regular swallowing function was regained and percutaneous gastrostomy could be removed.

Abstract
BACKGROUND Norway does not currently implement universal varicella vaccination in childhood. We aimed to characterize health care burden of varicella in Norway in the prevaccine era. METHODS We linked individual patient data from different national registries to examine varicella vaccinations and varicella-coded primary care consultations, hospitalizations, outpatient hospital visits, deaths and viral infections of central nervous system in the whole population of Norway during 2008-2014. We estimated health care contact rates and described the epidemiology of medically attended varicella infection. RESULTS Each year approximately 14,600 varicella-related contacts occurred within primary health care and hospital sector in Norway. The annual contact rate was 221 cases per 100,000 population in primary health care and 7.3 cases per 100,000 in hospital care. Both in primary and hospital care, the highest incidences were observed among children 1 year of age: 2,654 and 78.1 cases per 100,000, respectively. The annual varicella mortality was estimated at 0.06 deaths per 100,000 and in-hospital case-fatality rate at 0.3%. Very few (0.2-0.5%) patients were vaccinated against varicella. Among hospitalized varicella patients, 22% had predisposing conditions, 9% had severe-to-very severe comorbidities and 5.5% were immunocompromised. Varicella-related complications were reported in 29.3% of hospitalized patients. Varicella zoster virus was the third most frequent virus found among 16% of patients with confirmed viral infections of central nervous system. CONCLUSIONS Varicella causes a considerable health care burden in Norway, especially among children. To inform the policy decision on the use of varicella vaccination, a health economic assessment of vaccination and mathematical modeling of vaccination impact are needed.

Abstract
This study compared the Altona RealStar™ VZV Kit 1.0 real time quantitative VZV PCR with in-house qualitative conventional VZV PCR on cerebrospinal fluid, mucocutaneous, and other uncommon clinical specimens. Overall, positive and negative agreement percentages were respectively 97.9% (95%CI: 93.8-99.6), 100.0% (95%CI: 93.1-100.0), and 96.3% (95%CI: 89.4-99.2) while Cohen's kappa statistic value was 0.96 (95%CI: 0.91-1.00). RealStar™ VZV quantitative PCR assay reported average quantitative viral loads of 4.4 × 105 and 1.1 × 107 copies/mL in cerebrospinal fluid and cutaneous specimens, respectively (P < 0.01). RealStar™ VZV PCR assay showed excellent agreement with in house conventional assay for various clinical specimens.

Abstract
Herpes zoster (HZ) is a neurocutaneous disorder due to endogenous reactivation of the varicella-zoster virus (VZV). The typical clinical manifestation is an acute segmental eruption of herpetiform umbilicated vesicles associated with malaise, pain, dysaesthesia, allodynia and probably fever. This review focuses on other possible clinical manifestations of the disease to sensitize physicians not to overlook HZ since only an early antiviral treatment can reduce the risk of post-zosteric neuralgia.
