We encountered two cases of Herpes zoster (HZ) meningitis, a rarely occurring complication of HZ, in previously healthy children. One patient treated with i.v. acyclovir (ACV, 31 mg/kg/day) did not recover. His symptoms were relieved somewhat by increased ACV dosage, but it caused transient renal dysfunction. Another patient treated with i.v. ACV (30 mg/kg/day) recovered. Treatment for HZ meningitis in immunocompetent children has not been established. In a literature review, 80% of 20 patients were treated with the usual dose of ACV 15-30 mg/kg/day...

Before vaccination, varicella zoster virus (VZV), which is endemic worldwide, led to almost universal infection. This neurotropic virus persists lifelong by establishing latency in sensory ganglia, where its reactivation is controlled by VZV-specific T-cell immunity. Lifetime risk of VZV reactivation (zoster) is around 30%. Vaccine development was galvanised by the economic and societal burden of VZV, including debilitating zoster complications that largely affect older individuals. Areas covered: We describe the story of development, licensing and implementation of live attenuated vaccines against varicella and zoster...

Varicella zoster virus (VZV)-induced anterior uveitis (AU) may complicate the course of primary varicella infection typically seen in children. In adults, especially with advanced age, VZV AU is more commonly associated with herpes zoster ophthalmicus (HZO) with or without skin rash affecting the distribution of the ophthalmic nerve due to reactivation of the latent VZV in the trigeminal ganglion. While it is typically a mild self-limiting AU in primary infection, HZO AU is often accompanied by keratitis, may have a chronic recurrent course, and lead to sectoral iris atrophy, pupillary distortion, and ocular hypertension...

Posterior uveitis is an ocular complication that can occur with reactivation of varicella-zoster virus (VZV). It may lead to loss of vision due to retinal detachment and chronic inflammation, which often causes more severe disease than the virus infection itself. To increase our understanding of the immune response, we infected the retinal pigment epithelial (RPE) cell line, ARPE-19, with cell-associated VZV and compared its response to that of the MeWo cell line using multiplex assays. We observed (1) a difference in the magnitude and kinetics of cytokine responses between the 2 cell types and (2) differential migration of CD4+ and CD8+ T cells towards these cytokines...

PURPOSE: Acute retinal necrosis (ARN) is a panuveitis syndrome that may lead to severe complications such as cystoid macular edema (CME). There is no consensus about the best treatment. We report one case of CME secondary to ARN managed with intravitreal aflibercept. CASE REPORT: A 41-year-old woman with a history of successfully treated varicella-zoster virus-associated ARN developed an epiretinal membrane (ERM) and underwent pars plana vitrectomy, ERM removal, inner limiting membrane peel, and lensectomy...

A 56-year-old immunocompetent male developed brainstem encephalitis complicating Ramsay Hunt syndrome. The disease had a slowly progressing course of months after the triggering infection, much longer than previously reported. Furthermore, magnetic resonance imaging, physical-chemical, and cell count analyses on cerebrospinal fluid were normal, whereas polymerase chain reaction for varicella zoster virus DNA was positive. The simultaneous negativity of both imaging and basic CSF exams is very rare, although possible event which confirms the irreplaceable role of viral screening on CSF...

INTRODUCTION: Chickenpox is caused by varicella zoster virus (VZV). Although predominantly a mild disease, it can cause considerable morbidity and in rare occasions even mortality in healthy children as well as increased morbidity and mortality in immunocompromised patients. The aetiology of appendicitis is largely unknown but is thought to be multifactorial. Appendicitis is a suspected, but not well documented, complication from varicella zoster virus infection. CASE PRESENTATION: A five-year-old girl diagnosed with DiGeorge syndrome and a prolonged primary VZV infection was admitted due to abdominal pain, increasing diarrhoea, vomiting, and poor general condition...

Varicella zoster virus (VZV) infection has been implicated in multiple sclerosis (MS), but direct causal involvement has been disputed. Nevertheless, knowledge of VZV exposure is important, given the risk of serious complications of first exposure while undergoing immunosuppressive treatment, in particular with fingolimod. We distributed questionnaires to MS clinic patients, requesting information about history of chickenpox, sibling/household/occupational exposure, history of zoster (shingles), and disease-modifying treatment...

Ramsay hunt syndrome is not just a syndrome but it's rather an infectious disease caused by reactivation of latent varicella-zoster virus in geniculate ganglion. This was first explained by J. Ramsay Hunt as a triad of complications like otalgia, mucosal and cutaneous rashes with or without trigeminal facial palsy. The facial palsy can occur with characteristic vesicles along the path of nerve. We present a case of Ramsay Hunt syndrome in a 48-year-old male. The unilateral pattern of facial involvement and presence of vesicles assisted us for early diagnosis, distinguishing the syndrome with diseases mimicking other severe neurological illnesses and prompt treatment...

BACKGROUND: Saliva samples could be used for follow-up of herpesviruses infection in the pediatric transplant recipients. OBJECTIVE: With the aim of determining the frequency of herpesviral infections in saliva samples after transplantation, and the association with viremia and complications, a pilot longitudinal follow-up of pediatric Cuban transplanted recipients (kidney and liver) was performed. METHODS: Quantitative real-time polymerase chain reaction of cytomegalovirus (CMV), Epstein-Barr virus, herpes simplex virus, human herpesevirus-6 (HHV6), varicella zoster virus, and human herpesvirus-8 were serially assayed in saliva and serum samples from 27 transplanted patients, during 32 weeks after the graft...

A 64-year-old immunocompetent man developed a widespread pruritic and vesicular rash 2 weeks after receiving the zoster vaccine (Zostavax). He had fever, bandaemia with normal total white blood cell count and mild transaminitis. PCR testing of serum and skin was positive for varicella zoster virus (VZV), while serum VZV IgG was negative. The analysis of single nucleotide polymorphism by PCR and sequencing from the skin swab was consistent with the vaccine strain. The patient received 1 week of intravenous acyclovir and was discharged after all lesions had crusted...

Varicella pneumonia is one of the most serious, potentially life-threatening complications of primary varicella-zoster virus (VZV) infection in adults and immunocompromised individuals. However, studies on the lung pathogenesis of VZV infection as well as development and testing of antivirals have long been hindered by limited access to clinical samples and a lack of suitable animal models. In this study, we report for the first time the use of human lung xenografts in SCID mice for investigating VZV infection...

There is little information on herpes zoster infection in breast cancer patients as a complication during adjuvant chemotherapy. We report a case of herpes zoster in a 65-year-old woman presented with low grade fever and vital signs together with skin symptoms such as severe edema, irritation and itching in the left breast where there was wound drainage. PCR test revealed varicella zoster virus. To the best of our knowledge, the histologic features coupled with PCR led to a diagnosis of herpes zoster.

We treated 11 cases (52.7 ± 14.9 years, all male) with varicella zoster virus (VZV) meningitis and 437 cases with adult aseptic meningitis from 2004 to 2016. The incidence rate of adult VZV meningitis in the cases with aseptic meningitis was 2.5%. Herpes zoster infections are reported to have occurred frequently in summer and autumn. VZV meningitis also occurred frequently in the similar seasons, in our patients. The diagnoses were confirmed in 9 cases with positive VZV-DNA in the cerebrospinal fluid and in 2 cases with high VZV-IgG indexes (> 2...

BACKGROUND: In clinical trials, the addition of rituximab (RTX) to the combination therapeutic regimen of mycophenolate mofetil (MMF) and corticosteroids failed to improve outcome in lupus nephritis (LN). However, recent data suggest that RTX may have steroid-sparing beneficial effects with an efficacy similar to that of conventional regimens. We report our experience with RTX in the treatment of children with LN. METHODS: Patients treated with RTX for first occurrence of LN class III to V were enrolled in the study...

Varicella Zoster Virus (VZV) is a well-known virus that belongs to the Herpesviridae family which induces a self-limited disease except in specific cases in particular among stem cell transplant patients. This virus is not known however to trigger atypical Hemolytic Uremic Syndrome (aHUS). Here we report the case of a six-year-old boy who was hospitalized with fever and abdominal pains associated to pruritic and vesicular rash, thrombocytopenia and acute renal failure. He was diagnosed with aHUS precipitated by varicella virus...

Ramsay Hunt syndrome (herpes zoster oticus) is a rare complication of latent Varicella Zoster virus infection. It can be complicated by permanent hearing loss, loss of taste and postherpetic neuralgia. Although Ramsay Hunt syndrome most prominently involves the facial nerve, a number of other cranial nerves can be involved such as the vestibulocochlear, glossopharyngeal and the vagus nerve. We report on a case of Ramsay Hunt syndrome with cranial polyneuritis complicated by atrial fibrillation. Vagal involvement as evidenced by physical examination and MRI findings was present in our patient...
