Varicella Encephalitis

Miles H Beaman
Meningitis and encephalitis are medical emergencies. Patients need prompt evaluation and immediate empiric therapy to reduce the likelihood of fatal outcomes and chronic neurological sequelae. Conjugate bacterial vaccines have significantly reduced the incidence of bacterial meningitis, especially in children. As the results of changes in patterns of bacterial drug sensitivity, ceftriaxone is now part of the recommended empiric treatment for bacterial meningitis and should be administered as early as possible...

PURPOSE OF REVIEW: This article reviews the spectrum of neurologic disease associated with human herpesvirus infections. RECENT FINDINGS: As more patients are becoming therapeutically immunosuppressed, human herpesvirus infections are increasingly common. Historically, infections with human herpesviruses were described as temporal lobe encephalitis caused by herpes simplex virus type 1 or type 2. More recently, however, additional pathogens, such as varicella-zoster virus, Epstein-Barr virus, cytomegalovirus, and human herpesvirus 6 have been identified to cause serious neurologic infections...

Chickenpox (varicella) is primarily a disease of childhood which occurs due to infection with varicella-zoster virus (VZV). Primary VZV infection is rare in adults due to exposure in early childhood in our country. In adults, it is associated with some serious systemic and neurological complications which can follow both primary infection and reactivation of VZV. Neurological sequelae caused by primary VZV infection are rare and include encephalitis, aseptic meningitis, myelitis, acute cerebellar ataxia, Reye syndrome, Ramsay Hunt syndrome, and rarely stroke and cerebral venous thrombosis (CVT)...

Background: Varicella zoster virus (VZV) is distributed worldwide and is highly contagious. In adults and immunosuppressed patients of any age, the clinical course is much more severe. The most severe complications are pneumonia (the main cause of lethal outcomes in this infection), encephalitis, and very rarely Reye syndrome and hepatitis. Case Presentation: We present a 59-year-old man who came to the emergency department due to varicella and diarrhea. During initial evaluation acute kidney failure (AKF) was diagnosed, and the patient was admitted to the intensive care unit...

Ramsay Hunt syndrome (RHS) is an acute peripheral facial nerve paralysis typically accompanied by erythematous vesicular lesions of the auricular skin. The etiology is considered to be geniculate ganglionitis due to reactivation of varicella-zoster virus (VZV). Encephalitis is a rare but serious complication of VZV reactivation. Clarifying the regional and temporal evolution of the lesions on magnetic resonance imaging (MRI) would help with understanding the pathology of the lesion, but this information is lacking in encephalitis with RHS...

In most individuals, varicella zoster virus (VZV) causes varicella upon primary infection and zoster during reactivation. However, in a subset of individuals, VZV may cause severe disease, including encephalitis. Host genetics is believed to be the main determinant of exacerbated disease manifestations. Recent studies have demonstrated that defects in the DNA sensor RNA polymerase III (POL III) confer selective increased susceptibility to VZV infection, thus providing fundamental new insight into VZV immunity...

Hanalioğlu D, Özsürekci Y, Büyükçam A, Gültekingil-Keser A, Tekşam Ö, Ceyhan M. Acute peripheral facial paralysis following varicella infection: An uncommon complication. Turk J Pediatr 2018; 60: 99-101. Chickenpox is caused by varicella zoster virus (VZV/HHV-3), which is one of the eight human herpes viruses. Although chickenpox has a good prognosis, neurologic complications including encephalitis, acute cerebellar ataxia, myelitis and meningitis may seldom be associated with the disease. Peripheral facial palsy (PFP) is an extremely rare complication in patients with chickenpox...

There remains today a critical need for new antiviral agents, particularly in view of the alarming increase in drug resistance and associated issues. The marine environment has been a prolific contributor towards the identification of novel therapeutic agents in the recent few decades. Added to this, glycans (or carbohydrate- or sugar-based compounds) have in very recent decades made outstanding contributions to the development of novel therapeutics. This review brings together these significant facets of modern drug discovery by presenting the reported literature on glycans derived from marine organisms that possess antiviral activity...

Introduction: In 2019 and 2020, Japan will host two international sporting events estimated to draw a combined 22 million visitors. Mass gatherings like these ones increase the risk of spread of infectious disease outbreaks and international transmission. Pre-travel advice reduces that risk. Methods: To assist ministries of health and related organizations in developing pre-travel advice, we summarized national surveillance data in Japan (2000-2016, to the extent available) for rubella, invasive pneumococcal disease, measles, non-A and non-E viral hepatitis, hepatitis A, invasive Haemophilus influenzae disease, tetanus, typhoid fever, invasive meningococcal disease, Japanese encephalitis, influenza, varicella, mumps and pertussis by calculating descriptive statistics of reported cases and reviewing trends...

BACKGROUND: Spinal cystic arachnoiditis is a rare complication of a subarachnoid haemorrhage or infectious meningitis. The inflammatory process leads to fibrosis, adhesions, and in severe cases cyst formation. Large arachnoid cysts are an uncommon cause of compressive myelopathy. The majority are located posterior of the spinal cord at the thoracic level. Anterior cyst formation is exceptional, especially at the cervical region. CASE DESCRIPTION: We present 2 cases of progressive myelopathy secondary to anterior arachnoid cyst formation...

Background: Varicella zoster virus (VZV) may cause encephalitis, both with and without rash. Here we investigate whether viruses recovered from the central nervous system (CNS; encephalitis or meningitis) differ genetically from those recovered from non-CNS samples. Methods: Enrichment-based deep sequencing of 45 VZV genomes from cerebral spinal fluid (CSF), plasma, bronchoalveolar lavage (BAL), and vesicles was carried out with samples collected from 34 patients with and without VZV infection of the CNS...

We report a case of encephalitis associated with Zika virus infection and reactivation of varicella-zoster virus in the central nervous system of a Brazilian child. This case raises the possibility that reactivation of the latent varicella-zoster virus may be a mechanism of neurological impairment induced by acquired Zika virus infection.

The varicella zoster virus (VZV) is a neurotropic virus that becomes latent in the sensory ganglia, but later causes various neurologic complications such as meningitis, encephalitis, myelitis, meningoencephalitis, cranial neuropathy, and peripheral neuropathy [1]. While acute cerebellitis is one of the most frequent acute cerebellar diseases associated with VZV in childhood, VZV rarely causes cerebellitis in adults, with or without skin manifestations, and only a few isolated cases of adult VZV cerebellitis have been reported...

Herpes simplex virus (HSV) encephalitis is the most common cause of sporadic fatal encephalitis worldwide, and central nervous system (CNS) involvement is observed in approximately one-third of neonatal HSV infections . In recent years, single-gene inborn errors of innate immunity have been shown to be associated with susceptibility to HSV encephalitis . Temporal lobe abnormalities revealed by magnetic resonance imaging-the most sensitive imaging method for HSV encephalitis-are considered strong evidence for the disease...
