Varicella Zoster Virus (VZV) is a human-restricted α-herpesvirus that exhibits tropism for the skin. The VZV host receptors and downstream signaling pathways responsible for the antiviral innate immune response in the skin are not completely understood. Here, we show that stimulator of interferon genes (STING) mediates an important host defense against VZV infection in dermal cells including human dermal fibroblasts (HDFs) and HaCaT keratinocytes. Inhibition of STING using small interfering RNA (siRNA) or short hairpin RNA (shRNA)-mediated gene disruption resulted in enhanced viral replication but diminished IRF3 phosphorylation and induction of IFNs and pro-inflammatory cytokines...

Varicella and zoster continue to cause significant morbidity and even mortality in children and adults. Complications include bacterial superinfection, central nervous system manifestations such as meningitis, encephalitis, and cerebellar ataxia, and pain syndromes especially post herpetic neuralgia. Many developed countries but not all, are now administering live attenuated varicella vaccine routinely, with a decrease in the incidence of disease, providing personal and herd immunity. There is some controversy, however, in some countries concerning whether a decrease in the circulation of wild type virus will result in loss of immunity to VZV in persons who have already had varicella...

Introduction Varicella, although a frequently benign childhood disease, nevertheless represents a considerable health burden. WHO recommends including varicella vaccines in universal routine vaccination programs, and maintaining coverage >80%. Many countries have successfully introduced varicella vaccination and have benefited from lower disease burden, but many others have not adopted the vaccine. Reasons include cost commitment for a 'mild childhood disease' or concerns that vaccination will shift varicella to older age groups or increase herpes zoster incidence...

BACKGROUND: Anti-TNF agents have demonstrated to greatly improve management strategies for inflammatory bowel disease (IBD). Clinical trials and registry studies in Western countries have shown that infections and malignancy are the most concerned complications of anti-TNF treatment. However, data derived from clinical practice in China are limited. The aim of this study is to explore the long-term infection risk of infliximab (IFX) in treating patients with Crohn's disease (CD) from a tertiary IBD center in China...

BACKGROUND: Natalizumab is associated with the occasional occurrence of progressive multifocal leukoencephalopathy (PML). While natalizumab-associated PML is well described in multiple sclerosis (MS) patients, herpes and other infections have rarely been reported. OBJECTIVE: To report a case of varicella-zoster (VZV) meningovasculitis in a MS patient treated with natalizumab. METHODS: Case report. RESULTS: A 48-year-old woman diagnosed with MS in treatment with natalizumab (Expanded Disability Status Scale (EDSS): 4...

OBJECTIVE: Using data from 2003-2012, we updated a previous analysis of trends in hospitalizations of HIV-infected children and adolescents in the US. METHODS: We used data from the Kids´ Inpatient Database of the Healthcare Cost and Utilization Project to derive nationally representative estimates of the number of hospitalizations and the rates per 1000 hospitalizations of select discharge diagnoses and procedures in 2003, 2006, 2009, and 2012 among HIV-infected and HIV-uninfected children and adolescents ≤18 years, excluding hospitalizations for conditions related to pregnancy/delivery and neonatal diagnoses...

Mechanisms of neuronal infection by varicella-zoster virus (VZV) have been challenging to study due to the relatively strict human tropism of the virus and the paucity of tractable experimental models. Cellular mitogen activated protein kinases (MAPKs) have been shown to play a role in VZV infection of non-neuronal cells, with distinct consequences on infectivity in differing cell types. Here, we utilize several human neuronal culture systems to investigate the role of one such MAPK, the c-Jun N-terminal kinase (JNK), in VZV lytic infection and reactivation...

Importance: The effect of vaccination on emergency department (ED) utilization for herpes zoster (HZ) has not been examined to date. Objective: To determine trends in US ED utilization and costs associated with HZ. Design, Setting, and Participants: The Nationwide Emergency Department Sample data set was examined for temporal trends in the number of visits and costs for treatment of HZ in EDs in the United States from January 1, 2006, through December 31, 2013...

BACKGROUND AND PURPOSE: Aseptic infections of the central nervous system (CNS) are frequently observed in Germany. However, no study has systematically addressed the spectrum of aseptic CNS infections in Germany. METHODS: Data on 191 adult patients diagnosed from January 2007 to December 2014 with aseptic meningitis or encephalitis/meningoencephalitis at our hospital were collected by chart review and analyzed for demographic, clinical and laboratory findings. Patients were stratified according to the causative virus and findings were compared between groups...

Early events in herpes simplex virus type 1 (HSV-1) infection reactivate latent human immunodeficiency virus, Epstein-Barr virus, and human papillomavirus in the presence of acyclovir (ACV). The common use of nucleoside analog medications, such as ACV and pencyclovir, has resulted in the emergence of drug-resistant HSV-1 strains in clinical therapy. Therefore, new antiherpetics that can inhibit early events in HSV-1 infection should be developed. An example of this treatment is Houttuynia cordata Thunb. water extract, which can inhibit HSV-1 infection through multiple mechanisms...

BACKGROUND: Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis. The Oral Rheumatoid Arthritis triaL (ORAL) Strategy aimed to assess the comparative efficacy of tofacitinib monotherapy, tofacitinib plus methotrexate, and adalimumab plus methotrexate for the treatment of rheumatoid arthritis in patients with a previous inadequate response to methotrexate. METHODS: ORAL Strategy was a 1 year, double-blind, phase 3b/4, head-to-head, non-inferiority, randomised controlled trial in patients aged 18 years or older with active rheumatoid arthritis despite methotrexate therapy...

INTRODUCTION: Chronic uveitis treated with immunosuppressive agents may have unfavorable outcomes due to delays in diagnosis. The aim of this study was to review initial data from clinical and ocular assessments and patient outcomes following specific treatments for atypical herpes virus ocular infections.

BACKGROUND: Genetic variations have been identified in the genome of varicella-zoster virus (VZV) strains using vesicle fluid, varicella scabs and throat swab samples. We report a rare case of VZV-associated uveitis with severe hyphema, which was immediately diagnosed by polymerase chain reaction (PCR) using the aqueous humor, in which we were able to analyze the VZV genotype for the first time. CASE PRESENTATION: A 16-year-old Japanese boy was referred to our hospital with a 20-day history of unilateral anterior uveitis and 11-day history of hyphema...

INTRODUCTION: Varicella zoster virus is an exclusively human neurotrophic virus. The primary infection with the virus causes varicella. The virus remains latent in nervous tissue and upon secondary activation causes a variety of syndromes involving the central nervous system (CNS) including meningoencephalitis and cerebellitis. MATERIALS AND METHODS: In this study, we looked at the epidemiology, clinical and laboratory features, and outcomes of patients who were admitted with varicella zoster of the CNS from 2005 to 2014...
