AI Article Synopsis
- Reactivation of the latent varicella zoster virus in the trigeminal ganglion can lead to herpes zoster ophthalmicus, which is uncommon in children and usually diagnosed clinically without imaging.
- Recent studies on imaging abnormalities associated with this condition in children are limited.
- A new case report presents a healthy child with herpes zoster ophthalmicus who showed enlargement and enhancement of the trigeminal nerve and its branches on MRI, highlighting a potential imaging feature that hasn't been documented before in pediatric cases.
Article Abstract
Reactivation of latent varicella zoster virus in the trigeminal ganglion with involvement of the ophthalmic division of the trigeminal nerve causes herpes zoster ophthalmicus. This is rare in children and imaging is seldom performed since the diagnosis is primarily clinical. As a result, descriptions of the associated imaging abnormalities are sparse, particularly in the paediatric literature. We present the case of a previously healthy child with herpes zoster ophthalmicus who underwent a magnetic resonance imaging scan that demonstrated enlargement and enhancement of the ipsilateral trigeminal nerve and its branches. Our aim is to highlight this finding as a potential imaging feature of herpes zoster ophthalmicus, which, to our knowledge, has not previously been reported in children.

Low-Dose Acyclovir Reduces the Reactivation of Herpes Simplex and Varicella Zoster Viruses After Allogeneic Stem Cell Transplantation.

Introduction: Reactivation of herpes simplex virus (HSV) and varicella zoster virus (VZV) is a potential complication following allogeneic stem cell transplantation (alloSCT). Since different doses and durations of acyclovir prophylaxis may be utilized across transplant centers, this study aimed to evaluate the effectiveness of a lower dose of acyclovir in preventing HSV and VZV reactivation in alloSCT recipients within our institution.
Methods: A retrospective chart review was conducted for patients who underwent alloSCT between April 2016 and May 2023.
Metagenomic next-generation sequencing of cerebrospinal fluid: a diagnostic approach for varicella zoster virus-related encephalitis.

Purpose: Varicella zoster virus-related encephalitis (VZV-RE) is a rare and often misdiagnosed condition caused by an infection with the VZV. It leads to meningitis or encephalitis, with patients frequently experiencing poor prognosis. In this study, we used metagenomic next-generation sequencing (mNGS) to rapidly and accurately detect and identify the VZV pathogen directly from cerebrospinal fluid (CSF) samples, aiming to achieve a definitive diagnosis for encephalitis patients.

Herpes simplex virus type 1 (HSV-1) acyclovir (ACV) resistance is acquired by mutations in the viral thymidine kinase (TK) or DNA polymerase (DNApol) genes. We previously obtained an ACV-resistant clone (HSV-1_VZV_TK_clone α) by sequential passages of HSV-1_VZV-TK, a recombinant virus which lacked its endogenous TK activity and instead expressed the varicella-zoster virus (VZV) TK ectopically. HSV-1_VZV_TK_clone α had been generated using an HSV-1_BAC in the presence of increasing concentrations of ACV.

Herpes zoster (HZ) is a common disease in older adults and immunocompromised patients, and is frequently associated with long-term complications that impact quality of life. Fortunately, more than one vaccine against HZ is now available in Mexico. Two expert consensus groups discussed adult vaccination strategies in Mexico, focusing on HZ in older adults and immunocompromised individuals; their insights are reported here.

The burden of herpes zoster (HZ) is recognized worldwide; however, there is seemingly limited information on incidence and vaccination practices in Southeast Asia (SEA). A scientific workshop was held by the Zoster Experts' Network to exchange and consolidate insights on the burden of HZ and the patient pathway in SEA. The workshop included practicing clinical experts and public health specialists/epidemiologists from Indonesia, Malaysia, the Philippines, Thailand, and Vietnam.
