BACKGROUND: Primary varicella zoster virus (VZV) infection is a common illness, predominantly affecting children. Its course is typically benign, although severe complications have been described. Splenic rupture is an extremely rare and potentially fatal complication of primary VZV infection, with only a handful of cases reported in the literature. CASE PRESENTATION: A 32-year-old Romanian man with no significant past medical history, presented with a 2 day history of sudden onset, worsening generalised abdominal pain and a 1 day history of vomiting...

Background: Varicella zoster virus (VZV) can present as a myelopathy with spinal astrocyte infection. Recent studies support a role for the neurokinin-1 receptor (NK-1R) in virus infections, as well as for cytoskeletal alterations that may promote viral spread. Thus, we examined the role of NK-1R in VZV-infected primary human spinal astrocytes (HA-sps) to shed light on the pathogenesis of VZV myelopathy. Methods: Mock- and VZV-infected HA-sps were examined for substance P (subP) production, NK-1R localization, morphological changes and viral spread in the presence or absence of NK-1R antagonists, aprepitant and rolapitant...

Some epidemiological studies have implied a pathogenetic association between varicella zoster virus (VZV) and multiple sclerosis (MS); this, however, remains controversial. The present report describes a case involving an immunocompetent 10-year-old girl who developed relapsing-remitting MS following the prolonged reactivation of VZV inside the first branch of the trigeminal nerve, exhibiting herpes zoster ophthalmicus with severe optic neuritis. Symptoms related to herpes zoster ophthalmicus and MS appeared consecutively in the 10-week period after the appearance of vesicles...

Varicella zoster virus is a common viral infection with over 50% of patients over the age of 80 years infected with the virus. Following reactivation, some patients succumb to complications of VZV reactivation with neurologic and optic pathway pathology such as VZV vasculopathy resulting in transient ischemic attacks, strokes, aneurysms, as well as optic neuritis. We show that high resolution vessel wall magnetic resonance imaging can aid in the diagnosis of this condition with circumferential wall thickening and enhancement of the infected vessels...

Herpes zoster (HZ/shingles) is the clinical manifestation of varicella zoster virus (VZV) reactivation. HZ typically develops as people age due to decreased cell-mediated immunity. However, the importance of antibodies for immunity against HZ prevention remains to be understood. The goal of this study was to examine the breadth and functionality of VZV-specific antibodies after vaccination with a live attenuated HZ vaccine (Zostavax). Direct enumeration of VZV-specific antibody secreting cells (ASC) via ELISPOT showed that Zostavax can induce both IgG and IgA ASCs seven days after vaccination, but not IgM ASCs...

BACKGROUND: Varicella zoster virus (VZV) is a common herpesvirus infection that can result in acute varicella/chickenpox as well as delayed activation in herpes zoster/shingles. Ramsay-Hunt syndrome is a rare presentation of VZV reactivation, involving 1% of cases and resulting in lesion formation along the 7th cranial nerve distribution. We report the first case of a patient who presented with acute calvarial osteomyelitis after VZV reactivation and Propionibacterium acnes suprainfection...

Recently, deficiency in the cytosolic DNA sensor RNA Polymerase III was described in children with severe primary varicella-zoster virus (VZV) infection in the CNS and lungs. In the present study we examined adult patients with VZV CNS infection caused by viral reactivation. By whole exome sequencing we identified mutations in POL III genes in two of eight patients. These mutations were located in the coding regions of the subunits POLR3A and POLR3E. In functional assays, we found impaired expression of antiviral and inflammatory cytokines in response to the POL III agonist Poly(dA:dT) as well as increased viral replication in patient cells compared to controls...

Skin disorders vary greatly in symptoms and severity, and the causes of these disorders are largely unknown. Human herpesvirus (HHV) has been shown to cause many diseases. However, the prevalence and correlate of each HHV infection with different skin disorders remains obscure. To reveal the potential link of certain type of skin disease with herpesvirus infection, a total of 272 patient tissues with inflammatory or neoplastic skin diseases including 7 subtypes in Shanghai, China, were investigated. We found that the overall prevalence of HHV-6A in inflammatory or neoplastic skin tissues is the most common (40...

Varicella zoster virus (VZV) is a ubiquitous human alphaherpesvirus, responsible for varicella upon primary infection and herpes zoster following reactivation from latency. To establish lifelong infection, VZV employs strategies to evade and manipulate the immune system to its advantage in disseminating virus. As innate lymphocytes, natural killer (NK) cells are part of the early immune response to infection, and have been implicated in controlling VZV infection in patients. Understanding of how VZV directly interacts with NK cells, however, has not been investigated in detail...

Introduction: Post-herpetic neuralgia is a crippling complication of varicella zoster virus (VZV) reactivation, also known as zoster disease. In rare cases, VZV spreads to the spinal cord and causes myelitis. There is a paucity of data on spinal cord histopathology in the subacute phase of post-herpetic neuralgia and VZV myelitis. Case description: In this report, we present a case of post-herpetic neuralgia in a patient who died 5 weeks after initiation of symptoms...

AIM: Renal transplant patients are particularly susceptible to highly contagious diseases due to their reduced immunity. We studied transplant recipients to gauge their varicella zoster virus (VZV) serology status over time and the outcome of any VZV infections. METHOD: This retrospective study comprised 85 children who underwent renal transplants in Gothenburg, Sweden, from1986-2014, at a mean age of eight (1-18) years. The children's medical records were reviewed and 47 had the VZV infection pre-transplant and 38 had been vaccinated pre-transplant...

PURPOSE: Viral infections represent a serious threat for patients after liver transplantation (LT). The identification of risk factors during the early post-transplant period might help to improve prevention of viral infections after LT. METHODS: Between 2004 and 2010, 530 adult patients underwent LT at a large university hospital serving a metropolitan region in Europe. This retrospective single-centre study analysed putative risk factors for early viral infections with herpes simplex virus-1 (HSV-1), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), hepatitis A/B/C (HAV/HBV/HCV) and cytomegalovirus (CMV) in the first 3 months after LT...

Viral infections have been considered as possible destructive factors that influence male fertility. The aim of this study was to determine the prevalence of human herpes viruses 1-5 (HHV1-5), adeno associated virus (AAV) and human papilloma virus (HPV) in semen and whether these influence semen quality. DNA extraction was performed using phenol-chloroform protocol, then three different nested-PCRs were done to detect HHV1-5, AAV and HPV DNAs in the semen samples. Of 145 samples, 66 (45.5%) were positive at least for one of the viruses...

Overt aseptic meningitis rarely complicates varicella-zoster virus (VZV) reactivation in young and immunocompetent adults. Many of the cases of VZV meningitis are associated with an exanthem. We describe an otherwise healthy 36-year-old adult who had aseptic meningitis without skin rash, caused by reactivation of varicella-zoster virus. Cerebrospinal fluid (CSF) analysis revealed lymphocytosis, increased total protein, and low glucose. Diagnosis was made by polymerase chain reaction in CSF. The present case highlights the fact that VZV should be considered as a cause of aseptic meningitis with hypoglycorrhachia in healthy and young individuals, even in the absence of an exanthem...

Systemic lupus erythematosus (SLE) patients are at high risk of herpes zoster. Previously, we found increased immunoglobulin (Ig)G levels against varicella-zoster virus (VZV) in SLE patients compared to controls, while antibody levels against diphtheria and cellular immunity to VZV were decreased. We aimed to test our hypothesis that increased VZV-IgG levels in SLE result from subclinical VZV reactivations, caused by stress because of lupus disease activity or immunosuppressive drug use. Methods Antibody levels to VZV (IgG, IgA, IgM), total IgG and VZV-DNA were longitudinally determined in the serum of 34 SLE patients, using enzyme-linked immunosorbent assay and polymerase chain reaction...

Reactivation of varicella zoster virus (VZV) remains a significant public health burden for long-term survivors of hematopoietic cell transplantation. Delayed immune reconstitution after transplantation due to immunosuppression, posttransplant therapies, poor engraftment, and graft-versus-host disease leave a large number of patients at risk for herpes zoster (shingles) and its highly morbid complications. Although prophylaxis with acyclovir or valacyclovir has reduced the incidence of VZV reactivation as long as prophylaxis is continued, the incidence of disease in the late posttransplant period or after stopping prophylaxis is greater in the HCT population than the general public...
