    ABSTRACT Objective: Pathologic changes in varicella-zoster virus (VZV)–infected arteries include inflammation, thickened intima, and paucity of smooth muscle cells. Since no criteria have been established for early vs late VZV vasculopathy, we examined inflammatory cells and their distribution in 6 normal arteries, and 2 VZV-infected arteries 3 days after onset of disease (early) and 10 months after protracted neurologic disease (late). Methods: VZV-infected temporal artery obtained 3 days after onset of ischemic optic neuropathy from an 80-year-old man, VZV-infected middle cerebral artery (MCA) obtained 10 months after protracted disease from a 73-year-old man, and 5 MCAs and 1 temporal artery from normal subjects, age 22–60 years, were examined histologically and immunohistochemically using antibodies against VZV and inflammatory cell subsets. Results: In both early and late VZV vasculopathy, T cells, activated macrophages, and rare B cells were found in adventitia and intima. In adventitia of early VZV vasculopathy, neutrophils and VZV antigen were abundant and a thickened intima was associated with inflammatory cells in vaso vasorum vessels. In media of late VZV vasculopathy, viral antigen, but not leukocytes, was found. VZV was not seen in inflammatory cells. Inflammatory cells were absent in control arteries. Conclusions: Both VZV and neutrophils exclusively in adventitia in early VZV vasculopathy indicate that disease begins there. Late VZV vasculopathy is distinguished by viral antigen without inflammation in media, revealing a human virus in an immunoprivileged arterial media. Association of thickened intima and inflammation in vaso vasorum vessels in early VZV vasculopathy support the role of virus-induced inflammation in vessel wall remodeling. PMID:23243076

    There has been considerable interest in varicella-zoster virus in the middle of the twentieth century. Virus isolation in 1958 had made it possible to find out the complete DNA sequence of the varicella-zoster virus. Molecular identify of the causative agents of varicella and shingles had been proved. ETIOPATHOGENESIS AND HISTOPATHOLOGY: Varicella-zoster virus is a member of the Herpesviridae family. After primary infection which results in varicella, the virus becomes latent in the cerebral or posterior root ganglia. Some of these individuals develop shingles after several decades because of virus reactivation. It is caused by decline of cellular immune response. Circumstances such as old age, hard work, using of steroids or malignancies contribute to the appearance of shingles. Histopathological findings include degenerative changes of epithelial cells such as ballooning, multinucleated giant cells and eosinophilic intranuclear inclusions. Shingles occur sporadically, mainly among the elderly who have had varicella. There is no seasonal appearance of shingles. Individuals suffering from shingles may be sometimes contagious for susceptible children because of enormous amount of virus particles in vesicle fluid. Clinically, shingles is characterized at first by pain or discomfort in involved dermatome, usually without constitutional symptoms. Local edema and erythema appear before developing of rash. Maculopapular and vesicular rash evolves into crusts. The most commonly involved ganglia are: lumbar, thoracic, sacral posterior root ganglia, then geniculate ganglion of the VIIth cranial nerve and the trigeminal ganglion. The most common complication, postherpetic neuralgia, may last for as long as two or three weeks, sometimes even one year or more. Other complications that may be seen in shingles, but more rarely, are ocular (keratitis, iridocyclitis, secondary glaucoma, loss of sight), neurological (various motor neuropathies, encephalitis, Guillain-Barre syndrome

    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. 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. At presentation, details of the iris, the iridocorneal angle, and the fundus were not visible due to the severe hyphema. Serum anti-VZV IgG and anti-VZV IgM were elevated, and 1.61 × 10 9 copies/mL of VZV-DNA were detected by real-time PCR using the aqueous humor. As there were no eruptions on his face or body, we diagnosed zoster sine herpete and started intravenous administration of prednisolone and acyclovir. The hyphema completely disappeared 2 weeks after presentation, while sectorial iris atrophy and mild periphlebitis of the fundus became gradually apparent. Anterior inflammation and periphlebitis gradually improved and VZV-DNA in the aqueous humor was reduced to 1.02 × 10 6 copies/mL at 4 weeks after presentation. Examination by slit lamp microscope revealed no inflammation after 5 months, and VZV-DNA could no longer be detected in the aqueous humor. Serum anti-VZV IgG and anti-VZV IgM also showed a gradual decrease along with improvement in ocular inflammation. The genetic analysis of multiple open reading frames and the R5 variable repeat region in the VZV genes, using DNA extracted from the aqueous humor at presentation, showed that the isolate was a wild-type clade 2 VZV strain (prevalent in Japan and surrounding countries) with R5A allele and one SNP unique to clade 1 (both are major types in Europe and North America). VZV-associated uveitis may develop hyphema that obscures ocular inflammation, thus PCR analysis using the

    Full Text Available Chickenpox is due to infection with the varicella zoster virus (VZV, a human alphaherpervirus found worldwide. Classically, the cinical disease is a febrile illness with a pruritic vesicular rash. Maternal chickenpox between 5 days before delivery to 2 days after delivery (perinatal varicella can cause severe and even fatal illness in the newborn. A 7-day old girl baby presented on day 4 of postnatal with the complaints of widespread vesicular rash and non-suckling. Mother of the baby also had a similar eruption four day prior to delivery, which was clinically characteristic of varicella. Considering history and clinical presentation, a diagnosis of perinatal chickenpox was considered and the baby was treated with acyclovir which she responded and recovered. Herein, the clinical feasures and treatment of chickenpox infection in the perinatal period have been emphasized with this case report. [Cukurova Med J 2013; 38(2.000: 311-314

    The major features that distinguish recurrent herpes simplex virus infections from zoster are illustrated in this article by two case histories. The clinical and epidemiologic features that characterize recurrent herpes simplex virus and varicella-zoster virus infections are reviewed. It is noted that herpesvirus infections are more common and severe in patients with cellular immune deficiency. Each virus evokes both humoral and cellular immune response in the course of primary infection. DNA hybridization studies with RNA probes labelled with sulfur-35 indicate that herpes simplex viruses persist within neurons, and that varicella-zoster virus is found in the satellite cells that encircle the neurons

    1.Technology Description-Researchers discovered that when the Varicella Zoster Virus (VZV) reactivates from latency in the body, the virus is consistently present in saliva before the appearance of skin lesions. A small saliva sample is mixed with a specialized reagent in a test kit. If the virus is present in the saliva sample, the mixture turns a red color. The sensitivity and specificity emanates from an antibody-antigen reaction. This technology is a rapid, non-invasive, point of-of-care testing kit for detecting the virus from a saliva sample. The device is easy to use and can be used in clinics and in remote locations to quickly detect VZV and begin treatment with antiviral drugs. 2.Market Opportunity- RST Bioscience will be the first and only company to market a rapid, same day test kit for the detection of VZV in saliva. The RST detection test kit will have several advantages over existing, competitive technology. The test kit is self contained and laboratory equipment is not required for analysis of the sample. Only a single saliva sample is required to be taken instead of blood or cerebral spinal fluid. The test kit is portable, sterile and disposable after use. RST detection test kits require no electrical power or expensive storage equipment and can be used in remote locations. 3.Market Analysis- According to the CDC, it is estimated that 1 million cases of shingles occur each year in the U.S. with more than half over the age of sixty. There is a high demand for rapid diagnostics by the public. The point-of-care testing (POCT) market is growing faster than other segments of in vitro diagnostics. According to a July 2007 InteLab Corporation industry report the overall market for POCT was forecast to increase from $10.3 billion in 2005 to $18.7 billion by 2011. The market value of this test kit has not been determined. 4.Competition- The VZV vaccine prevents 50% of cases and reduces neuralgia by 66%. The most popular test detects VZV-specific IgM antibody

    Varicella zoster virus (VZV) is the causative agent of varicella (chicken pox) and herpes zoster (shingles). After primary infection, the virus remains latent in sensory ganglia, and reactivates upon weakening of the cellular immune system due to various conditions, erupting from sensory neurons and infecting the corresponding skin tissue. The current varicella vaccine (v-Oka) is highly attenuated in the skin, yet retains its neurovirulence and may reactivate and damage sensory neurons. The reactivation is sometimes associated with postherpetic neuralgia (PHN), a severe pain along the affected sensory nerves that can linger for years, even after the herpetic rash resolves. In addition to the older population that develops a secondary infection resulting in herpes zoster, childhood breakthrough herpes zoster affects a small population of vaccinated children. There is a great need for a neuro-attenuated vaccine that would prevent not only the varicella manifestation, but, more importantly, any establishment of latency, and therefore herpes zoster. The development of a genetically-defined live-attenuated VZV vaccine that prevents neuronal and latent infection, in addition to primary varicella, is imperative for eventual eradication of VZV, and, if fully understood, has vast implications for many related herpesviruses and other viruses with similar pathogenic mechanisms.

    Herpes zoster is a viral infection caused by the reactivation of the varicella zoster virus. One of the less well-recognized maxillofacial complications is tooth root resorption. To our knowledge, this is the first case report about internal resorption associated with varicella zoster virus involving different dental quadrants. A 38-year-old woman presented with internal resorption of maxillary canine and first premolar tooth roots on the right quadrant and generalized internal resorption of second molars of both mandibular quadrants. The patient's medical history showed mild oral lichen planus and infection with varicella zoster virus (chickenpox) with severe clinical manifestations 5 years previously. The patient developed diabetes mellitus type I and hypothyroidism a short time after varicella zoster virus infection, and by the time of infection with this virus, oral lichen planus had progressed from the reticular pattern to the generalized severe erosive form. Viral etiology could also be considered in these diseases. The root canals of the affected teeth were debrided, irrigated, and dried, and calcium hydroxide paste was placed in the root canals for a week during the first treatment session. The root canals were obturated during the second session. Six-month follow-up showed improvement of oral lichen planus and resolution of widening of periodontal ligament of the affected teeth, with follow-up radiographs revealing no periapical problems. It appears some cases of internal root resorption classified as idiopathic might have viral etiology. Therefore, it is recommended that patients be questioned about a history of chickenpox and herpes zoster. Copyright © 2015 American Association of Endodontists. Published by Elsevier Inc.

    Spaceflight is a uniquely stressful environment with astronauts experiencing a variety of stressors including: isolation and confinement, psychosocial, noise, sleep deprivation, anxiety, variable gravitational forces, and increased radiation. These stressors are manifested through the HPA and SAM axes resulting in increased stress hormones. Diminished T-lymphocyte functions lead to reactivation of latent herpes viruses in astronauts during spaceflight. Herpes simplex virus reactivated with symptoms during spaceflight whereas Epstein-Barr virus (EBV), cytomegalovirus (CMV), and varicella zoster virus (VZV) reactivate and are shed without symptoms. EBV and VZV are shed in saliva and CMV in the urine. The levels of EBV shed in astronauts increased 10-fold during the flight; CMV and VZV are not typically shed in low stressed individuals, but both were shed in astronauts during spaceflight. All herpesviruses were detected by polymerase chain reaction (PCR) assay. Culturing revealed that VZV shed in saliva was infectious virus. The PCR technology was extended to test saliva of 54 shingles patients. All shingles patients shed VZV in their saliva, and the levels followed the course of the disease. Viremia was also found to be common during shingles. The technology may be used before zoster lesions appear allowing for prevention of disease. The technology may be used for rapid detection of VZV in doctors? offices. These studies demonstrated the value of applying technologies designed for astronauts to people on Earth.

    Varicella-zoster virus (VZV) causes chickenpox after which the virus remains latent in neural ganglia. Subsequent reactivation episodes occur, leading mainly to subclinical detection of VZV, but also to the clinical entity herpes zoster. These reactivations are known to occur most frequently amongst immunocompromised individuals, but the incidence of herpes zoster is also known to increase with age, supposedly as a consequence of immunosenescence. Our analysis aims to explore associations bet...

    Aerosol borne varicella zoster virus (VZV) enters the nasopharynx and replicates in tonsillar T-cells, resulting in viremia and varicella (chickenpox). Virus then becomes latent in cranial nerve, dorsal root and autonomic nervous system ganglia along the entire neuraxis (1). Decades later, as cell-mediated immunity to VZV declines (4), latent VZV can reactivate to produce zoster (shingles). Infectious VZV is present in patients with varicella or zoster, but shed of infectious virus in the absence of disease has not been shown. We previously detected VZV DNA in saliva of astronauts during and shortly after spaceflight, suggesting stress induced subclinical virus reactivation (3). We show here that VZV DNA as well as infectious virus in present in astronaut saliva. VZV DNA was detected in saliva during and after a 13-day spaceflight in 2 of 3 astronauts (Fig. panel A). Ten days before liftoff, there was a rise in serum anti-VZV antibody in subjects 1 and 2, consistent with virus reactivation. In subject 3, VZV DNA was not detected in saliva, and there was no rise in anti-VZV antibody titer. Subject 3 may have been protected from virus reactivation by having zoster DNA was detected in astronaut saliva months before spaceflight, or in saliva of 10 age/sex-matched healthy control subjects sampled on alternate days for 3 weeks (88 saliva samples). Saliva taken 2-6 days after landing from all 3 subjects was cultured on human fetal lung cells (Fig. panel B). Infectious VZV was recovered from saliva of subjects 1 and 2 on the second day after landing. Virus specificity was confirmed by antibody staining and DNA analysis which showed it to be VZV of European descent, common in the US (5). Further, both antibody staining and DNA PCR demonstrated that no HSV-1 was detected in any infected culture. This is the first report of infectious VZV shedding in the absence of clinical disease. Spaceflight presents a uniquely stressful environment which includes physical isolation and

Epidemiological studies from geographical areas, where incidence of MS has increased in recent decades, pointed out a high frequency of varicella and zoster in the clinical antecedents of MS patients, and also laboratory investigations have found large quantities of DNA from VZV in leucocytes and cerebrospinal fluid of MS patients restricted to the ephemeral period of MS relapse, followed by disappearance of the virus during remission.

    BackgroundHerpes zoster vaccine is currently recommended in the United States for immune competent individuals ≥60 years. The efficacy of the herpes zoster vaccine decreases with age and with time following vaccination.PurposeAn elderly man with herpes zoster following vaccination is described. The guidelines for vaccination and issues regarding re-vaccination are reviewed. PubMed was used to search the following terms: efficacy, elderly, herpes zoster, herpes zoster incidence, herpes zoster recurrence, and vaccination. The papers and relevant citations were reviewed. The clinical features of a patient with post-vaccination herpes zoster skin infection are presented; in addition, vaccine efficacy and guidelines are reviewed.ResultsA 91-year-old man, vaccinated for herpes zoster 10 years earlier, presented with crusted erosions on his face corresponding to the area innervated by the ophthalmic division of the left trigeminal nerve. Evaluation using polymerase chain reaction confirmed the diagnosis of herpes zoster.ConclusionsHerpes zoster vaccine decreases in efficacy with both age and number of years following vaccination. Therefore, booster shots or revaccination in the older population may be of benefit.

    No formal epidemiological research based on systematic analysis has focused on the relationship between herpes zoster and immunodeficiency virus (HIV) infection in Taiwan. Our aim was to explore whether herpes zoster is an early manifestation of undiagnosed human HIV infection in Taiwan. This was a retrospective cohort study using the database of the Taiwan National Health Insurance Program. A total of 35,892 individuals aged ≤ 84 years with newly diagnosed herpes zoster from 1998 to 2010 were assigned to the herpes zoster group, whereas 143,568 sex-matched and age-matched, randomly selected individuals without herpes zoster served as the non-herpes zoster group. The incidence of HIV diagnosis at the end of 2011 was estimated in both groups. The multivariable Cox proportional hazards regression model was used to estimate the hazard ratio and 95% confidence interval (CI) for risk of HIV diagnosis associated with herpes zoster and other comorbidities including drug dependence and venereal diseases. The overall incidence of HIV diagnosis was 4.19-fold greater in the herpes zoster group than that in the non-herpes zoster group (3.33 per 10,000 person-years vs. 0.80 per 10,000 person-years, 95% CI 4.04-4.35). The multivariable Cox proportional hazards regression analysis revealed that the adjusted hazard ratio of HIV diagnosis was 4.37 (95% CI 3.10-6.15) for individuals with herpes zoster and without comorbidities, as compared with individuals without herpes zoster and without comorbidities. Herpes zoster is associated with HIV diagnosis. Patients who have risk behaviors of HIV infection should receive regular surveillance for undiagnosed HIV infection when they present with herpes zoster. Copyright © 2015. Published by Elsevier B.V.

Combined with our previous finding of BMS due to herpes simplex virus type 1 (HSV-1) infection, we recommend evaluation of patients with BMS not only for VZV or HSV-1 DNA in the saliva, but also for serum anti-VZV and anti-HSV-1 IgM antibodies.

    ABSTRACT Varicella-zoster virus (VZV) is a human herpesvirus, which during primary infection typically causes varicella (chicken pox) and establishes lifelong latency in sensory and autonomic ganglia. Later in life, the virus may reactivate to cause herpes zoster (HZ; also known as shingles). To prevent these diseases, a live-attenuated heterogeneous vaccine preparation, vOka, is used routinely in many countries worldwide. Recent studies of another alphaherpesvirus, infectious laryngotracheitis virus, demonstrate that live-attenuated vaccine strains can recombine in vivo, creating virulent progeny. These findings raised concerns about using attenuated herpesvirus vaccines under conditions that favor recombination. To investigate whether VZV may undergo recombination, which is a prerequisite for VZV vaccination to create such conditions, we here analyzed 115 complete VZV genomes. Our results demonstrate that recombination occurs frequently for VZV. It thus seems that VZV is fully capable of recombination if given the opportunity, which may have important implications for continued VZV vaccination. Although no interclade vaccine-wild-type recombinant strains were found, intraclade recombinants were frequently detected in clade 2, which harbors the vaccine strains, suggesting that the vaccine strains have already been involved in recombination events, either in vivo or in vitro during passages in cell culture. Finally, previous partial and complete genomic studies have described strains that do not cluster phylogenetically to any of the five established clades. The additional VZV strains sequenced here, in combination with those previously published, have enabled us to formally define a novel sixth VZV clade. IMPORTANCE Although genetic recombination has been demonstrated to frequently occur for other human alphaherpesviruses, herpes simplex viruses 1 and 2, only a few ancient and isolated recent recombination events have hitherto been demonstrated for VZV.

MATERIAL E MÉTODO: Estudo prospectivo com 171 pacientes com PFP, sendo 120 pacientes portadores de paralisia de Bell, com até uma semana de evolução, sem uso prévio de drogas antivirais. O grupo controle foi composto de 20 adultos sadios. Nestes indivíduos foram coletadas três amostras de saliva em semanas consecutivas, para pesquisa de DNA viral pela técnica de PCR. RESULTADOS: O vírus varicela zoster foi encontrado em amostras de saliva de dois pacientes com paralisia de Bell (1,7%. Nenhum vírus foi identificado no grupo controle. CONCLUSÃO: Foi verificada frequência de 1,7% para vírus varicela zoster em amostras de saliva de pacientes com paralisia de Bell, pela técnica de PCR.Although Bell's palsy is the major cause of acute peripheral facial palsy, its pathogenesis remains unknown. Reactivation of the varicella zoster virus has been implicated as one of the main causes of Bell's palsy, however, studies which investigate the varicella zoster virus reactivation in Bell's palsy patients are mostly Japanese and, therefore, personal and geographic characteristics are quite different from our population. AIMS: To determine varicella zoster virus frequency in saliva samples from patients with Bell's palsy, using PCR.

    Lysates of radiolabeled explants from four human trigeminal ganglia were immunoprecipitated with antibodies to varicella-zoster virus (VZV) and to herpes simplex virus. Both herpes simplex virus- and VZV-specific proteins were detected in lysates of all four ganglia. Absence of reactivity in ganglion explants with monoclonal antibodies suggested that herpes simplex virus and VZV were not reactivated during the culture period. In situ hybridization studies demonstrated the presence of RNA transcripts from the VZV immediate early gene 63. This approach to the detection of herpes simplex virus and VZV expression in human ganglia should facilitate analysis of viral RNA and proteins in human sensory ganglia

    In this case report we present an otherwise healthy 63 year-old male patient with herpes zoster corresponding to the 2nd left branch of the trigeminal nerve. Real time-polymerase chain reaction analyses were positive for both herpes simplex virus (HSV) type 1 and varicella zoster virus (VZV......). The most probable explanation is that this reflects asymptomatic, latent expression of HSV-1 in a herpes zoster patient with no clinical relevance. Another hypothesis is that reactivation of a neurotropic herpes virus can reactivate another neurotropic virus if both types are present in the same ganglion....... If co-infection with HSV/VZV is suspected the treatment regimen for herpes zoster will sufficiently treat a possible HSV infection also....

    Varicella zoster virus (VZV) causes chicken pox on first exposure (usually in children), and reactivates from latency causing shingles (usually in adults). Shingles can be extremely painful, causing nerve damage, organ damage, and blindness in some cases. The virus can be life-threatening in immune-compromised individuals. The virus is very difficult to culture for diagnosis, requiring a week or longer. This invention is a rapid test for VZV from a saliva sample and can be performed in a doctor s office. The kit is small, compact, and lightweight. Detec tion is sensitive, specific, and noninvasive (no needles); only a saliva sample is required. The test provides results in minutes. The entire test is performed in a closed system, with no exposure to infectious materials. The components are made mostly of inexpensive plastic injection molded parts, many of which can be purchased off the shelf and merely assembled. All biological waste is contained for fast, efficient disposal. This innovation was made possible because of discovery of a NASA scientists flight experiment showing the presence of VZV in saliva during high stress periods and disease. This finding enables clinicians to quickly screen patients for VZV and treat the ones that show positive results with antiviral medicines. This promotes a rapid recovery, easing of pain and symptoms, and reduces chances of complications from zoster. Screening of high-risk patients could be incorporated as part of a regular physical exam. These patients include the elderly, pregnant women, and immune-compromised individuals. In these patients, VZV can be a life-threatening disease. In both high- and low-risk patients, early detection and treatment with antiviral drugs can dramatically decrease or even eliminate the clinical manifestation of disease.

    Full Text Available Antimony compounds are the cornerstone treatments for tegumentary leishmaniasis. The reactivation of herpes virus is a side effect described in few reports. We conducted an observational study to describe the incidence of herpes zoster reactivation during treatment with antimony compounds. The global incidence of herpes zoster is approximately 2.5 cases per 1,000 persons per month (or 30 cases per 1,000 persons per year. The estimated incidence of herpes zoster in patients undergoing antimony therapy is higher than previously reported.

    Varicella zoster virus (VZV) is an occupational hazard for a percentage of health care staff. Nine hundred and seventy staff members attending the Occupational Health Department at Cork University Hospital took part in the survey. A latex agglutination assay was used to determine the health care workers immune status to VZV. Of the 970 workers tested, 928 (95.7%) were immune to VZV. The sensitivity, specificity and predictive value of an enquiry regarding a history of chicken-pox was determined on a sample of 206 health care workers. The positive predictive value was 95% (119\\/125) and the negative predictive value was 11% (4\\/35). The sensitivity of the enquiry was 79% (119\\/150), the specificity was 40% (4\\/10), reducing to 61% (119\\/195) and 36% (4\\/11) respectively when individuals with uncertain histories were included in the calculations. The advantages and disadvantages of selective staff screening are discussed. In the authors\\' opinion all health care workers involved in the clinical care of patients should be screened by serology for past VZV infection before taking up duty and those who are susceptible to VZV should be made aware of the risks and health effects associated with VZV if contracted.

    The incidence and severity of herpes zoster (HZ) increases with age. The live attenuated zoster vaccine generates immune responses similar to HZ. We compared the immune responses to zoster vaccine in young and older to adults to increase our understanding of the immune characteristics that may contribute to the increased susceptibility to HZ in older adults. Young (25-40 y; n = 25) and older (60-80 y; n = 33) adults had similar magnitude memory responses to varicella-zoster virus (VZV) ex vivo restimulation measured by responder cell-frequency and flow cytometry, but the responses were delayed in older compared with young adults. Only young adults had an increase in dual-function VZV-specific CD4 + and CD8 + T cell effectors defined by coexpression of IFN-γ, IL-2, and CD107a after vaccination. In contrast, older adults showed marginal increases in VZV-specific CD8 + CD57 + senescent T cells after vaccination, which were already higher than those of young adults before vaccination. An increase in VZV-stimulated CD4 + CD69 + CD57 + PD1 + and CD8 + CD69 + CD57 + PD1 + T cells from baseline to postvaccination was associated with concurrent decreased VZV-memory and CD8 + effector responses, respectively, in older adults. Blocking the PD1 pathway during ex vivo VZV restimulation increased the CD4 + and CD8 + proliferation, but not the effector cytokine production, which modestly increased with TIM-3 blockade. We conclude that high proportions of senescent and exhausted VZV-specific T cells in the older adults contribute to their poor effector responses to a VZV challenge. This may underlie their inability to contain VZV reactivation and prevent the development of HZ. Copyright © 2017 by The American Association of Immunologists, Inc.

  11. Role for the Ventral Posterior Medial/Posterior Lateral Thalamus and Anterior Cingulate Cortex in Affective/Motivation Pain Induced by Varicella Zoster Virus

    Full Text Available Varicella zoster virus (VZV infects the face and can result in chronic, debilitating pain. The mechanism for this pain is unknown and current treatment is often not effective, thus investigations into the pain pathway become vital. Pain itself is multidimensional, consisting of sensory and affective experiences. One of the primary brain substrates for transmitting sensory signals in the face is the ventral posterior medial/posterior lateral thalamus (VPM/VPL. In addition, the anterior cingulate cortex (ACC has been shown to be vital in the affective experience of pain, so investigating both of these areas in freely behaving animals was completed to address the role of the brain in VZV-induced pain. Our lab has developed a place escape avoidance paradigm (PEAP to measure VZV-induced affective pain in the orofacial region of the rat. Using this assay as a measure of the affective pain experience a significant response was observed after VZV injection into the whisker pad and after VZV infusion into the trigeminal ganglion. Local field potentials (LFPs are the summed electrical current from a group of neurons. LFP in both the VPM/VPL and ACC was attenuated in VZV injected rats after inhibition of neuronal activity. This inhibition of VPM/VPL neurons was accomplished using a designer receptor exclusively activated by a designer drug (DREADD. Immunostaining showed that cells within the VPM/VPL expressed thalamic glutamatergic vesicle transporter-2, NeuN and DREADD suggesting inhibition occurred primarily in excitable neurons. From these results we conclude: (1 that VZV associated pain does not involve a mechanism exclusive to the peripheral nerve terminals, and (2 can be controlled, in part, by excitatory neurons within the VPM/VPL that potentially modulate the affective experience by altering activity in the ACC.

    2006-01-01

    Herpes zoster is caused by reactivation of latent varicella-zoster virus that resides in a dorsal root ganglion. Herpes zoster can develop any time after a primary infection. Because varicella vaccine is a live attenuated virus, herpes zoster can develop in a vaccine recipient. The incidence of herpes zoster among vaccine recipients is about 14 cases per 100,000 person-years. In young children, herpes zoster has a predilection for areas supplied by the cervical and sacral dermatomes. The most common complications are secondary bacterial infection, depigmentation, and scarring. Although the diagnosis of herpes zoster is based on a distinct clinical appearance, viral DNA analysis of the lesion by polymerase chain reaction or restriction fragment length polymorphism is necessary to differentiate wild from vaccine-type viruses. Acyclovir is the treatment of choice for herpes zoster.

    Herpes simplex virus type 1 (HSV-1; human herpesvirus 1) and varicella-zoster virus (VZV; human herpesvirus 3) are human neurotropic alphaherpesviruses that cause lifelong infections in ganglia. Following primary infection and establishment of latency, HSV-1 reactivation typically results in herpes labialis (cold sores), but can occur frequently elsewhere on the body at the site of primary infection (e.g. whitlow), particularly at the genitals. Rarely, HSV-1 reactivation can cause encephalitis; however, a third of the cases of HSV-1 encephalitis are associated with HSV-1 primary infection. Primary VZV infection causes varicella (chickenpox) following which latent virus may reactivate decades later to produce herpes zoster (shingles), as well as an increasingly recognized number of subacute, acute and chronic neurological conditions. Following primary infection, both viruses establish a latent infection in neuronal cells in human peripheral ganglia. However, the detailed mechanisms of viral latency and reactivation have yet to be unravelled. In both cases latent viral DNA exists in an 'end-less' state where the ends of the virus genome are joined to form structures consistent with unit length episomes and concatemers, from which viral gene transcription is restricted. In latently infected ganglia, the most abundantly detected HSV-1 RNAs are the spliced products originating from the primary latency associated transcript (LAT). This primary LAT is an 8.3 kb unstable transcript from which two stable (1.5 and 2.0 kb) introns are spliced. Transcripts mapping to 12 VZV genes have been detected in human ganglia removed at autopsy; however, it is difficult to ascribe these as transcripts present during latent infection as early-stage virus reactivation may have transpired in the post-mortem time period in the ganglia. Nonetheless, low-level transcription of VZV ORF63 has been repeatedly detected in multiple ganglia removed as close to death as possible. There is increasing

In general, primary infections in tropical regions are comparatively less frequent among children than in temperate regions. This peculiarity regarding varicella-zoster virus (VZV) infection among certain age groups in tropical regions results in increased susceptibility during adulthood in these regions.

    Full Text Available Abstract Background Varicella and herpes zoster are both caused by varicella zoster virus (VZV infection or reactivation and may lead to complications associated with a (severe societal burden. Because the epidemiology of VZV-related diseases in the Netherlands remains largely unknown or incomplete, the main objective of this study was to study the primary care incidence, associated complications and health care resource use. Methods We investigated the incidence of VZV complications in the Dutch general practitioner (GP practices and pharmacies in a retrospective population-based cohort study (2004–2008 based on longitudinal GP data including free text fields, hospital referral and discharge letters from approximately 165,000 patients. Results The average annual incidence of varicella GP-consultations was 51.5 per 10,000 (95% CI 44.4-58.7 overall; 465.5 per 10,000 for 0–1 year-olds; 610.8 per 10,000 for 1–4 year-olds; 153.5 per 10,000 for 5–9 year-olds; 8,3 per 10,000 for >10 year olds. When only ICPC coded diagnoses were analyzed the incidence was 27% lower. The proportion of complications among varicella patients was 34.9%. Most frequently complications were upper respiratory tract infections. Almost half of the varicella patients received medication. The referral rate based on GP consultations was 1.7%. The average annual incidence of herpes zoster GP-consultations was 47.5 per 10,000 (95% CI 40.6-54.4. The incidence increased with age; 32.8 per 10,000 for 65 year olds. When estimating herpes zoster incidence only on ICPC coded information, the incidence was 28% lower. The complication rate of herpes zoster was 32.9%. Post herpetic neuralgia was seen most often. Of patients diagnosed with herpes zoster 67.8% received medication. The referral rate based on GP consultations was 3.5%. Conclusions For varicella the highest incidence of GP-consultations was found in 1–4 year-olds, for herpes zoster in the >65 years olds

  2. Estimation of age-specific rates of reactivation and immune boosting of the varicella zoster virus

    Full Text Available Studies into the impact of vaccination against the varicella zoster virus (VZV have increasingly focused on herpes zoster (HZ, which is believed to be increasing in vaccinated populations with decreasing infection pressure. This idea can be traced back to Hope-Simpson's hypothesis, in which a person's immune status determines the likelihood that he/she will develop HZ. Immunity decreases over time, and can be boosted by contact with a person experiencing varicella (exogenous boosting or by a reactivation attempt of the virus (endogenous boosting. Here we use transmission models to estimate age-specific rates of reactivation and immune boosting, exogenous as well as endogenous, using zoster incidence data from the Netherlands (2002–2011, n = 7026. The boosting and reactivation rates are estimated with splines, enabling these quantities to be optimally informed by the data. The analyses show that models with high levels of exogenous boosting and estimated or zero endogenous boosting, constant rate of loss of immunity, and reactivation rate increasing with age (to more than 5% per year in the elderly give the best fit to the data. Estimates of the rates of immune boosting and reactivation are strongly correlated. This has important implications as these parameters determine the fraction of the population with waned immunity. We conclude that independent evidence on rates of immune boosting and reactivation in persons with waned immunity are needed to robustly predict the impact of varicella vaccination on the incidence of HZ.

  3. Dendritic cells as Achilles' heel and Trojan horse during varicella zoster virus infection

    Directory of Open Access Journals (Sweden)

    Günther eSchönrich

    2015-05-01

    Full Text Available Varicella zoster virus (VZV, a human alphaherpesvirus, causes varicella and subsequently estab-lishes latency within sensory nerve ganglia. Later in life VZV can reactivate to cause herpes zoster. A reduced frequency of VZV-specific T cells is strongly associated with herpes zoster illustrating that these immune cells are central to control latency. Dendritic cells (DCs are required for the generation of VZV-specific T cells. However, DCs can also be infected in vitro and in vivo allowing VZV to evade the antiviral immune response. Thus, DCs represent the immune systems’ Achilles heel. Uniquely among the human herpesviruses, VZV infects both DCs and T cells, and exploits both as Trojan horses. During primary infection VZV-infected DCs traffic to the draining lymph nodes and tonsils, where the virus is transferred to T cells. VZV-infected T cells subsequently spread infection throughout the body to give the typical varicella skin rash. The delicate interplay between VZV and DCs and its consequences for viral immune evasion and viral dissemination will be discussed in this article.

    Progressive outer retinal necrosis (PORN) associated with varicella zoster virus (VZV) is usually diagnosed in HIV positive or immunosuppressed patients. We report two cases of immunocompetent patients with necrotizing viral retinitis found to have idiopathic CD4 lymphocytopenia. Clinical presentation, examination, imaging, and laboratory testing of two patients with VZV retinitis are presented. An HIV negative patient with history of herpes zoster presented with rapid loss of vision and examination consistent with PORN. PCR testing confirmed VZV. Lymphocytopenia was noted with a CD4 count of 25/mm(3). A second HIV negative patient presented with blurred vision and lid swelling and was found to have peripheral VZV retinitis confirmed by PCR. Laboratory workup revealed lymphocytopenia with a CD4 count of 133/mm(3). VZV necrotizing retinitis classic for PORN can occur in HIV negative patients. Idiopathic CD4 lymphocytopenia should be considered healthy patients who develop ocular infections seen in the immunocompromised.

    Ronald Albert Benton Carey

    2017-01-01

    Full Text Available 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. Results: There were 17 patients. Fever was present in 13 patients, seizures in 9 patients and headache and vomiting in 4 patients each. A generalized varicella rash was present in 8 out of 17 patients. A single dermatomal herpes zoster was present in seven patients. Two patients had no rash. Varicella zoster polymerase chain reaction (PCR in cerebrospinal fluid (CSF was done in 5 patients of which 4 were positive and 1 was negative. Nine patients had diabetes with an average glycated hemoglobin of 8.6%. Total number of deaths was five. Conclusions: Patients with diabetes who develop varicella or herpes zoster may be at risk for CNS complications. The diagnosis of varicella encephalitis has to rest on a combination of clinical findings and CSF PCR, as neither the rash nor the PCR is sensitive enough to diagnose all the cases with varicella encephalitis.

    Autophagy is a process by which misfolded and damaged proteins are sequestered into autophagosomes, before degradation in and recycling from lysosomes. We have extensively studied the role of autophagy in varicella-zoster virus (VZV) infection, and have observed that vesicular cells are filled with >100 autophagosomes that are easily detectable after immunolabeling for the LC3 protein. To confirm our hypothesis that increased autophagosome formation was not secondary to a block, we examined all conditions of VZV infection as well as carrying out two assessments of autophagic flux. We first investigated autophagy in human skin xenografts in the severe combined immunodeficiency (SCID) mouse model of VZV pathogenesis, and observed that autophagosomes were abundant in infected human skin tissues. We next investigated autophagy following infection with sonically prepared cell-free virus in cultured cells. Under these conditions, autophagy was detected in a majority of infected cells, but was much less than that seen after an infected-cell inoculum. In other words, inoculation with lower-titered cell-free virus did not reflect the level of stress to the VZV-infected cell that was seen after inoculation of human skin in the SCID mouse model or monolayers with higher-titered infected cells. Finally, we investigated VZV-induced autophagic flux by two different methods (radiolabeling proteins and a dual-colored LC3 plasmid); both showed no evidence of a block in autophagy. Overall, therefore, autophagy within a VZV-infected cell was remarkably different from autophagy within an HSV-infected cell, whose genome contains two modifiers of autophagy, ICP34.5 and US11, not present in VZV.

    Varicella-zoster virus (VZV) causes chickenpox after which the virus remains latent in neural ganglia. Subsequent reactivation episodes occur, leading mainly to subclinical detection of VZV, but also to the clinical entity herpes zoster. These reactivations are known to occur most frequently amongst immunocompromised individuals, but the incidence of herpes zoster is also known to increase with age, supposedly as a consequence of immunosenescence. Our analysis aims to explore associations between cytomegalovirus (CMV) infection and VZV reactivation by analyzing VZV-specific antibody titers as a function of age, gender, and CMV serostatus. The analysis was repeated on measles and parvovirus B19 antibody titers. At the time of the observations, measles virus circulation was virtually eliminated, whereas parvovirus B19 circulated at lower levels than VZV. Multiple linear regression analyses, using the log-transformed antibody titers, identified a positive association between ageing and VZV antibody titers suggesting that ageing increasingly stimulates VZV reactivation. CMV infection further amplified the positive association between ageing and the reactivation rate. A negative association between CMV infection and VZV antibody titers was found in young individuals, thereby supporting the hypothesis that CMV infection may have a negative effect on the number of B-cells. However, no associations between CMV infection and measles or parvovirus B19 antibody titers occurred, but ageing tended to be associated with a decrease in the antibody titer against parvovirus B19. The combined results thus suggest that both CMV-dependent and CMV-independent immunosenescence occurs. This is supported by an in-depth analysis of VZV, measles and parvovirus B19 antibody titers. © 2013 Wiley Periodicals, Inc.

    Varicella-zoster virus (VZV) is renowned for its low titers. Yet investigations to explore the low infectivity are hampered by the fact that the VZV particle-to-PFU ratio has never been determined with precision. Herein, we accomplish that task by applying newer imaging technology. More than 300 images were taken of VZV-infected cells on 4 different samples at high magnification. We enumerated the total number of viral particles within 25 cm(2) of the infected monolayer at 415 million. Based on these numbers, the VZV particle:PFU ratio was approximately 40,000:1 for a cell-free inoculum.

    Herpesviruses are among the most complex and widespread viruses, infection and propagation of which depend on envelope proteins. These proteins serve as mediators of cell entry as well as modulators of the immune response and are attractive vaccine targets. Although envelope proteins are known to carry glycans, little is known about the distribution, nature, and functions of these modifications. This is particularly true for O-glycans; thus we have recently developed a “bottom up” mass spectrometry-based technique for mapping O-glycosylation sites on herpes simplex virus type 1. We found wide distribution of O-glycans on herpes simplex virus type 1 glycoproteins and demonstrated that elongated O-glycans were essential for the propagation of the virus. Here, we applied our proteome-wide discovery platform for mapping O-glycosites on representative and clinically significant members of the herpesvirus family: varicella zoster virus, human cytomegalovirus, and Epstein-Barr virus. We identified a large number of O-glycosites distributed on most envelope proteins in all viruses and further demonstrated conserved patterns of O-glycans on distinct homologous proteins. Because glycosylation is highly dependent on the host cell, we tested varicella zoster virus-infected cell lysates and clinically isolated virus and found evidence of consistent O-glycosites. These results present a comprehensive view of herpesvirus O-glycosylation and point to the widespread occurrence of O-glycans in regions of envelope proteins important for virus entry, formation, and recognition by the host immune system. This knowledge enables dissection of specific functional roles of individual glycosites and, moreover, provides a framework for design of glycoprotein vaccines with representative glycosylation.

    Bell's palsy is considered the most common cause of facial nerve paralysis in children. Although different theories have been postulated for its diagnosis, reactivation of the Varicella zoster virus (VZV) has been implicated as one of the causes of Bell's palsy. The aim of the study was to evaluate the association of Varicella-zoster virus infection with Bell's palsy and its outcome in children. A total of 30 children with Bell's palsy were recruited and were assayed for evidence of VZV infection. The severity of facial nerve dysfunction and the recovery rate were evaluated according to House-Brackmann Facial Nerve Grading Scale (HB FGS). Paired whole blood samples from all patients were obtained at their initial visit and 3 weeks later, and serum samples were analyzed for VZV IgG and IgM antibodies using ELISA. A significantly higher percentage of Bell's palsy patients were seropositive for VZV IgM antibodies than controls (36.6% of patients vs 10% of controls) while for VZV IgG antibodies the difference was statistically nonsignificant. HB FGS in Bell's palsy patients with serologic evidence of VZV recent infection or reactivation showed a statistiacally significant less cure rate than other patients. VZV reactivation may be an important cause of acute peripheral facial paralysis in children. The appropriate diagnosis of VZV reactivation should be done to improve the outcome and the cure rate by the early use of antiviral treatment. Copyright © 2014 Elsevier Ireland Ltd.

    It has been shown that varicella zoster virus (VZV) and herpes simplex virus (HSV) can co-localize to the same sensory ganglion. However, only a few case reports on VZV/HSV co-infections exist. Objective To identify and characterize patients with concurrent VZV and HSV infection at the same body site. In 1718 patients, the presence of VZV and HSV in suspicious skin lesions was investigated by polymerase chain reaction analysis. Clinical characteristics of co-infected patients were compared with matched control patients infected with either VZV or HSV. The data are discussed in the context of an extensive review of the literature. Twenty (1.2%) of 1718 patients were infected with both VZV and HSV at the same body site. The mean age was 54 years (range, 2-83). The clinical diagnosis was zoster in 65%, herpes simplex in 20%, varicella in 10% and erythema multiforme in 5% of cases. The trigeminus region was affected in 60% and the trunk in 25%. Involvement of the head was most commonly associated with a severe course of disease and with older age. Simultaneous VZV/HSV infection is rare but can occur in immunocompetent patients, which is often overlooked. The majority of cases is localized to the trigeminus region and affects elderly people.

    Full Text Available Objective: It is controversial whether microorganisms play a role in the pathogenesis of large and medium vessel vasculitides (eg, giant cell arteritis [GCA], Takayasu arteritis [TAK] and focal idiopathic aortitis [FIA]. Recent studies have reported the presence of Varicella Zoster Virus (VZV within formalin-fixed, paraffin-embedded temporal arteries and aortas of about three-quarters or more of patients with these conditions, and in a minority of controls. In a prospective study, we sought to confirm these findings using DNA extracted from vessels that were harvested under surgically aseptic conditions and snap frozen. Methods and Results: DNA samples extracted from 11 surgically sterile temporal arteries and 31 surgically sterile thoracic aortas were used in an attempt to identify the vessel-associated VZV genome. Two different validated PCR methods were used. Thirty-one thoracic aorta aneurysm specimens included biopsies from 8 patients with GCA, 2 from patients with TAK, 6 from patients with FIA, and 15 from patients without vasculitis, who had non-inflammatory aneurysms. Eleven temporal artery biopsies were collected from 5 patients with GCA and 6 controls. The presence of VZV was not identified in either the specimens from patients with large vessel vasculitis or from the controls. Conclusions: Using surgically sterile snap-frozen specimens, we were unable to confirm recent reports of the presence of VZV in either aortas or temporal arteries from patients with large vessel vasculitis or controls.

    We report varicella-zoster virus (VZV) gastritis in a 70-year-old woman postchemotherapy for lymphoma, presenting with abdominal pain, vomiting, and delirium without rash. A gastric biopsy demonstrated viral inclusions but posed a diagnostic challenge as immunohistochemistry for cytomegalovirus and herpes simplex virus were negative, and VZV immunohistochemistry was not available. The patient developed a vesicular rash 7 days after her symptoms began. Molecular testing of the gastric biopsy and a skin swab both confirmed VZV infection. She also had probable involvement of her liver and pancreas based on imaging and serum chemistry, and possible central nervous system involvement. She recovered with appropriate antiviral therapy but later developed a postherpetic neuralgia, and chronic intrahepatic biliary strictures; liver biopsy demonstrated a cholangiopathy of uncertain etiology. A literature review of the pathogenesis, epidemiology and sequelae of VZV infection is included.

    Varicella zoster virus (VZV) causes varicella and herpes zoster. These vaccine preventable diseases are common globally. Most available data on VZV epidemiology are from industrialised temperate countries and cannot be used to guide decisions on the immunization policy against VZV in Africa. This systematic review aims to review the published data on VZV morbidity and mortality in Africa. All published studies conducted in Africa from 1974 to 2015 were eligible. Eligible studies must have reported any VZV epidemiological measure (incidence, prevalence, hospitalization rate and mortality rate). For inclusion in the review, studies must have used a defined VZV case definition, be it clinical or laboratory-based. Twenty articles from 13 African countries were included in the review. Most included studies were cross-sectional, conducted on hospitalized patients, and half of the studies used varying serological methods for diagnosis. VZV seroprevalence was very high among adults. Limited data on VZV seroprevalence in children showed very low seropositivity to anti-VZV antibodies. Co-morbidity with VZV was common. There is lack of quality data that could be used to develop VZV control programmes, including vaccination, in Africa. PROSPERO 2015: CRD42015026144 .

    Full Text Available Identification of the factors affecting reactivation of varicella-zoster virus (VZV largely remains an open question. Exposure to solar ultra violet (UV radiation is speculated to facilitate reactivation. Should the role of UV in reactivation be significant, VZV reactivation patterns would generally be expected to be synchronous with seasonal UV profiles in temperate climates.We analysed age and gender specific VZV notification time series data from Perth, Western Australia (WA. This city has more daily sunshine hours than any other major Australian city. Using the cosinor and generalized linear models, we tested these data for seasonality and correlation with UV and temperature.We established significant seasonality of varicella notifications and showed that while herpes-zoster (HZ was not seasonal it had a more stable seasonal component in males over 60 than in any other subpopulation tested. We also detected significant association between HZ notifications and UV for the entire Perth population as well as for females and males separately. In most cases, temperature proved to be a significant factor as well.Our findings suggest that UV radiation may be important for VZV reactivation, under the assumption that notification data represent an acceptably accurate qualitative measure of true VZV incidence.

    Full Text Available Abstract Objective: To characterize varicella zoster virus-related deaths and hospitalizations in Brazil before universal vaccination with the tetravalent (measles, mumps, rubella, and varicella vaccine, attempting to collect baseline data on varicella morbidity and mortality in order to evaluate the impact of the varicella vaccination program. Methods: Varicella-associated mortality data were evaluated between 1996 and 2011 and varicella zoster virus-associated hospitalizations between 1998 and 2013. Data were gathered from the Informatics Department of the Unified Health System, considering the International Classification of Diseases, 10th Revision, code B01. All age groups were assessed. Varicella-specific mortality rates were calculated and seasonality of varicella-zoster virus-associated hospitalizations was described. Results: There were 2334 varicella deaths between 1996 and 2011, 19.3% in infants aged less than 1 year and 36% in children from 1 to 4 years. In infants under 1 year, varicella mortality rates reached 3.2/100,000/year. In children aged 1–4 years, varicella mortality rates reach 1.64/100,000/year. Average annual mortality rates for varicella in Brazil are 0.88/100,000 in infants under 1 year and 0.40/100,000 in children aged 1–4 years. The total number of hospitalizations associated with varicella zoster virus was 62,246 from 2008 to 2013. Varicella-associated hospitalizations have a seasonal distribution in children, peaking in November. In the elderly, monthly averages of herpes zoster-associated hospitalizations present no significant seasonal variation. Conclusions: Varicella is associated, in the pre-vaccine period, to significant morbidity and mortality in Brazil. The universal vaccination program is expected to decrease the disease burden from varicella.

    Syncytia formation has been considered important for cell-to-cell spread and pathogenesis of many viruses. As a syncytium forms, individual nuclei often congregate together, allowing close contact of nuclear membranes and possibly fusion to occur. However, there is currently no reported evidence of nuclear membrane fusion between adjacent nuclei in wild-type virus-induced syncytia. Varicella-zoster virus (VZV) is one typical syncytia-inducing virus that causes chickenpox and shingles in humans. Here, we report, for the first time, an interesting observation of apparent fusion of the outer nuclear membranes from juxtaposed nuclei that comprise VZV syncytia both in ARPE-19 human epithelial cells in vitro and in human skin xenografts in the SCID-hu mouse model in vivo. This work reveals a novel aspect of VZV-related cytopathic effect in the context of multinucleated syncytia. Additionally, the information provided by this study could be helpful for future studies on interactions of viruses with host cell nuclei. Copyright © 2017 Elsevier Inc. All rights reserved.

    The licensed live, attenuated varicella-zoster virus vaccine prevents herpes zoster in adults older than 50 years. We aimed to determine whether intradermal administration of zoster vaccine could enhance vaccine immunogenicity compared with conventional needle subcutaneous administration. In this randomised, dose-ranging study, adults aged 50 years or older who had a history of varicella or who had resided in a country with endemic varicella-zoster virus infection for 30 years or more were eligible. Participants received the approved full or a 1/3 dose of zoster vaccine given subcutaneously or one of four intradermal doses (full, 1/3, 1/10, or 1/27 dose) using the MicronJet600 device. The two subcutaneous doses and the four intradermal doses were randomised (1·5:1:1:1:1:1) by computer generated sequence with randomisation stratified by age (50-59 years or 60 years or older). The primary immunogenicity endpoint was the change from baseline in IgG antibody to varicella-zoster virus-specific glycoproteins (gpELISA) measured at 6 weeks. All patients were included in the primary and safety analyses. This study is registered with ClinicalTrials.gov, number NCT01385566. Between Sept 2, 2011, and Jan 13, 2012, 224 participants were enrolled from three clinics in the USA and 223 were randomly assigned: 52 to receive the full dose subcutaneous zoster vaccine, 34 to receive the 1/3 dose subcutaneous zoster vaccine, 34 to receive the full dose intradermal zoster vaccine, 35 to receive the 1/3 dose intradermal zoster vaccine, 34 to receive the 1/10 dose intradermal zoster vaccine, and 34 to receive the 1/27 dose intradermal zoster vaccine. Full dose zoster vaccine given subcutaneously resulted in a gpELISA geometric mean fold-rise (GMFR) of 1·74 (90% CI 1·48-2·04) at 6 weeks post-vaccination compared with intradermal administration which resulted in a significantly higher gpELISA GMFR of 3·25 (2·68-3·94; p<0·0001), which also remained high at 18 months.

    BACKGROUND: Primary varicella infection is caused by varicella-zoster virus (VZV). It is a common childhood infection, which is usually benign but can occasionally cause morbidity and mortality. In immunosuppressed adults, atypical presentation and disseminated disease can occur with significant morbidity and mortality. A VZV vaccine is available. OBJECTIVES: This study was designed to measure the prevalence of immunity to VZV and to determine the predictive value of a self-reported history of varicella infection in a population of dermatological patients receiving systemic immunosuppressant therapy. We sought to assess the need for routine serological testing for varicella-zoster immunity in this cohort. METHODS: Serological testing for VZV immunity was done on 228 patients receiving systemic immunosuppressive treatment for a dermatological condition. Information regarding a history of previous primary VZV infection was obtained from each patient. RESULTS: Two hundred and twenty-eight patients had VZV serology performed. The mean age of the patients was 49.6 years. The prevalence of VZV seropositivity in this cohort was 98.7%. One hundred and two patients (44.7%) reported having a definite history of primary VZV. The sensitivity of a self-reported history of VZV infection was 45.3% with a specificity of 100%. The positive and negative predictive values of a self-reported history of VZV for serologically confirmed immunity were 100% and 2.3%, respectively. CONCLUSIONS: The prevalence of VZV IgG antibodies in our cohort of Irish dermatology patients receiving immunosuppressive therapy is 98.7%. A recalled history of varicella infection is a good predictor of serological immunity. This study has shown that there are VZV-susceptible individuals within our cohort. These patients did not have a clear history of previous infection. We recommend serological testing of patients without a clear history of infection prior to the commencement of immunosuppressive therapy and

    The neurotropic herpesvirus varicella-zoster virus (VZV) establishes a lifelong latent infection in humans following primary infection. The low abundance of VZV nucleic acids in human neurons has hindered an understanding of the mechanisms that regulate viral gene transcription during latency. To overcome this critical barrier, we optimized a targeted capture protocol to enrich VZV DNA and cDNA prior to whole-genome/transcriptome sequence analysis. Since the VZV genome is remarkably stable, it was surprising to detect that VZV32, a VZV laboratory strain with no discernible growth defect in tissue culture, contained a 2,158-bp deletion in open reading frame (ORF) 12. Consequently, ORF 12 and 13 protein expression was abolished and Akt phosphorylation was inhibited. The discovery of the ORF 12 deletion, revealed through targeted genome sequencing analysis, points to the need to authenticate the VZV genome when the virus is propagated in tissue culture. IMPORTANCE Viruses isolated from clinical samples often undergo genetic modifications when cultured in the laboratory. Historically, VZV is among the most genetically stable herpesviruses, a notion supported by more than 60 complete genome sequences from multiple isolates and following multiple in vitro passages. However, application of enrichment protocols to targeted genome sequencing revealed the unexpected deletion of a significant portion of VZV ORF 12 following propagation in cultured human fibroblast cells. While the enrichment protocol did not introduce bias in either the virus genome or transcriptome, the findings indicate the need for authentication of VZV by sequencing when the virus is propagated in tissue culture.

    A sensitive radioimmunoassay for serum antibody to varicella-zoster virus is described; it uses 125I-labeled staphylococcal protein A and a specially designed immunofiltration apparatus. The assay accurately distinguishes between individuals who are susceptible and those who are immune to infection with varicella-zoster virus. In addition, it can detect passive antibody in recipients of varicella-zoster immune globulin. This radioimmunoassay also detects the heterologous antibody responses that occasionally occur in patients infected with herpes simplex virus, which also have been detected by other antibody assays. The particular advantages of this assay are the use of noninfectious reagents, the speed of execution (less than 3 hr), the requirement for only small quantities of serum (30 microliters), the objectivity of end-point determination, and the capability of screening large numbers of sera. Consequently, this radioimmunoassay is especially useful for the rapid identification of susceptible individuals, which is essential for the appropriate management of patients and hospital personnel after exposure to varicella

    To analyze the difference in the degree of divergence between genes from identical herpes virus species, we examined the nucleotide sequence of genes from the herpes simplex virus type 1 (HSV-l ) strains VR-3 and 17 encoding thymidine kinase (TK), deoxyribonuclease (DNase), protein kinase (PK; UL13) and virion-associated host shut off (vhs) protein (UL41). The frequency of nucleotide substitutions per 1 kb in TK gene was 2.5 to 4.3 times higher than those in the other three genes. To prove that the polymorphism of HSV-1 TK gene is common characteristic of herpes virus TK genes, we compared the diversity of TK genes among eight HSV-l , six herpes simplex virus type 2 (HSV-2) and seven varicella-zoster virus (VZV) strains. The average frequency of nucleotide substitutions per 1 kb in the TK gene of HSV-l strains was 4-fold higher than that in the TK gene of HSV-2 strains. The VZV TK gene was highly conserved and only two nucleotide changes were evident in VZV strains. However, the rate of non-synonymous substitutions in total nucleotide substitutions was similar among the TK genes of the three viruses. This result indicated that the mutational rates differed, but there were no significant differences in selective pressure. We conclude that HSV-l TK gene is highly diverged and analysis of variations in the gene is a useful approach for understanding the molecular evolution of HSV-l in a short period. (authors)

    Eleven isolates of varicella-zoster virus were tested for their effects on the incorporation of [ 14 C]acetate into lipids in infected human embryonic lung cells. By relative percent, all virus isolates demonstrated a shift from polar lipid synthesis to neutral lipid, especially triglyceride, synthesis. By data expressed as counts per minute per microgram of protein, the VZV strains could be separated into two groups: those strains which depressed lipid synthesis and those strains which did not depress, and may even have stimulated, lipid, especially triglyceride, synthesis. These results may be useful in understanding the development of lipid changes seen in children affected with Reye's syndrome following chickenpox

    The varicella-zoster virus (VZV) causes chickenpox (varicella) as the primary disease and shingles (zoster) as a recurrent manifestation of infection, both being generality benign and self-limiting. While these infections may be severe in adults and even life-threatening in immunosuppressed individuals, they may be amenable to effective antiviral drugs or varicella-zoster immune globulin, provided the treatment is administered early. The prompt diagnosis of VZV infections may be accelerated by rapid, sensitive and specific molecular techniques such as amplification by polymerase chain reaction (PCR) compared with slower and more cumbersome tissue culture and serological procedures. Based on the VZV gene 4 which encodes a transcriptional activator, primers were designed for use in PCR to amplify a target fragment of 381 bp. Distinct diagnostic bands were observed by agarose gel electrophoresis of PCR products of VZV strains isolated from II varicella and 7 zoster patients in Singapore, as well as of the Japanese vaccine Oka strain. The detection sensitivity of this PCR assay was determined to be 1 pg of purified VZV DNA equivalent to about 7,000 viral DNA copies. No target bands were amplified from negative control templates from five related human herpes-viruses and from human DNA. The specificity of the PCR products was ensured by direct cycle DNA sequencing, which revealed complete identity of the 18 VZV isolates with the published European Dumas strain. The strong sequence conservation of the target fragment renders this PCR assay highly reliable for detecting the VZV sequence. Only one VZV strain isolated from a patient with varicella during pregnancy exhibited a Gaga to GAA point mutation at codon 46 of gene 4, culminating in the non-conservative substitution of Ser with Phe. The predicted secondary structure of the mutant polypeptide portrayed a radical alteration, which may influence its function in transcriptional activation. (authors)

    The goal of this minireview is to provide an overview of varicella-zoster virus (VZV) phylogenetics and phylogeography when placed in the broad context of geologic time. Planet Earth was formed over 4 billion years ago, and the supercontinent Pangaea coalesced around 400 million years ago (mya). Based on detailed tree-building models, the base of the phylogenetic tree of the Herpesviridae family has been estimated at 400 mya. Subsequently, Pangaea split into Laurasia and Gondwanaland; in turn, Africa rifted from Gondwanaland. Based on available data, the hypothesis of this minireview is that the ancestral alphaherpesvirus VZV coevolved in simians, apes, and hominins in Africa. When anatomically modern humans first crossed over the Red Sea 60,000 years ago, VZV was carried along in their dorsal root ganglia. Currently, there are five VZV clades, distinguishable by single nucleotide polymorphisms. These clades likely represent continued VZV coevolution, as humans with latent VZV infection left Arabia and dispersed into Asia (clades 2 and 5) and Europe (clades 1, 3, and 4). The prototype VZV sequence contains nearly 125,000 bp, divided into 70 open reading frames. Generally, isolates within a clade display >99.9% identity to one another, while members of one clade compared to a second clade show 99.8% identity to one another. Recently, four different VZV genotypes that do not segregate into the previously defined five clades have been identified, a result indicating a wider than anticipated diversity among newly collected VZV strains around the world.

    The aim of the study was to determine VZV seroprevalence under age 30 and to identify the relationship of VZV seroprevalence and several sociodemographic characteristics of the study subjects. The results were presented in order to design a strategy for vaccination against varicella-zoster virus (VZV). It was planned to include a total of 568 subjects. The sampling method of 30 clusters recommended for field studies was used for selecting subjects of a predetermined number in the rural and urban areas in eastern Turkey. ELISA method was used to examine the blood samples for VZV seropositivity. Age, gender, place of living, educational level, family size and socioeconomic status was investigated in the study subjects. Positive VZV seroprevalence was detected in 78% of 559 subjects. Seroprevalence increased with age. Seroprevalence was 16.67% at the age of 1 year, subsequently increased to 57.58% at the age of 4 years, 70% at the age of 7 years, 92.31% at the age of 10 years and then remained 86.78-96.36% in subjects over the age of 10 years. No association was found between sociodemographic variables studied and prevalence levels of antibodies except for educational level in the 0-14 year group. These results suggest that the majority of VZV infections occur during the early childhood; the best option to reduce the circulation of wild type VZV in the population would be the immunization of young children. VZV vaccine should be introduced into the routine childhood vaccination programme in Turkey.

    Full Text Available Purpose. To describe a case of anterior nodular scleritis, preceded by an anterior hypertensive uveitis, which was primarily caused by varicella zoster virus (VZV. Case Report. A 54-year-old woman presented with anterior uveitis of the right eye presumably caused by herpetic viral disease and was successfully treated. Two months later, she developed a nodular scleritis and started oral nonsteroidal anti-inflammatory without effect. A complete laboratory workup revealed positivity for HLA-B27; the infectious workup was negative. Therapy was changed to oral prednisolone and an incomplete improvement occurred. Therefore, a diagnostic anterior paracentesis was performed and the polymerase chain reaction (PCR analysis revealed VZV. She was treated with valacyclovir and the oral prednisolone began to decrease; however, a marked worsening of the scleritis occurred with the reduction of the daily dose; subsequently, methotrexate was introduced allowing the suspension of the prednisolone and led to clinical resolution of the scleritis. Conclusion. This report of anterior nodular scleritis caused by VZV argues in favor of an underlying immune-mediated component, requiring immunosuppressive therapy for clinical resolution. The PCR analysis of the aqueous humor was revealed to be a valuable technique and should be considered in cases of scleritis with poor response to treatment.

    It is controversial whether microorganisms play a role in the pathogenesis of large and medium vessel vasculitides (eg, giant cell arteritis [GCA], Takayasu arteritis [TAK] and focal idiopathic aortitis [FIA]). Recent studies have reported the presence of Varicella Zoster Virus (VZV) within formalin-fixed, paraffin-embedded temporal arteries and aortas of about three-quarters or more of patients with these conditions, and in a minority of controls. In a prospective study, we sought to confirm these findings using DNA extracted from vessels that were harvested under surgically aseptic conditions and snap frozen. DNA samples extracted from 11 surgically sterile temporal arteries and 31 surgically sterile thoracic aortas were used in an attempt to identify the vessel-associated VZV genome. Two different validated PCR methods were used. Thirty-one thoracic aorta aneurysm specimens included biopsies from 8 patients with GCA, 2 from patients with TAK, 6 from patients with FIA, and 15 from patients without vasculitis, who had non-inflammatory aneurysms. Eleven temporal artery biopsies were collected from 5 patients with GCA and 6 controls. The presence of VZV was not identified in either the specimens from patients with large vessel vasculitis or from the controls. Using surgically sterile snap-frozen specimens, we were unable to confirm recent reports of the presence of VZV in either aortas or temporal arteries from patients with large vessel vasculitis or controls.

    Primary varicella zoster virus (VZV) infection, predominantly in the pediatric population, presents with pyrexia and a classic pruritic vesicular rash. In adults, although less common, it is more severe and linked to more complications. Neurological complications, which account for less than 1% of all VZV complications, include meningitis, encephalitis, arterial vasculopathy, and venous thrombosis. We present a case of a 39-year-old male who developed extensive cerebral venous sinus thrombosis following primary VZV infection. Venous thrombosis in VZV has been suggested to be caused by autoantibodies against protein S, pre-existing hypercoagulability, or endothelial damage. The patient was acutely managed using intravenous acyclovir and heparin. Long-term anticoagulation therapy with warfarin was continued after discharge. We concluded that clinicians should be aware of the rare complications of this common pathology so that a timely diagnosis can be made, followed by prompt management. Further studies need to be done to better understand acute cerebral venous sinus thrombosis secondary to VZV.

    Full Text Available Abstract Background Varicella-zoster virus (VZV causes chickenpox in children and shingles in older people. Currently, live attenuated vaccines based on the Oka strain are available worldwide. In Korea, an attenuated VZV vaccine has been developed from a Korean isolate and has been commercially available since 1994. Despite this long history of use, the mechanism for the attenuation of the vaccine strain is still elusive. We attempted to understand the molecular basis of attenuation mechanism by full genome sequencing and comparative genomic analyses of the Korean vaccine strain SuduVax. Results SuduVax was found to contain a genome that was 124,759 bp and possessed 74 open reading frames (ORFs. SuduVax was genetically most close to Oka strains and these Korean-Japanese strains formed a strong clade in phylogenetic trees. SuduVax, similar to the Oka vaccine strains, underwent T- > C substitution at the stop codon of ORF0, resulting in a read-through mutation to code for an extended form of ORF0 protein. SuduVax also shared certain deletion and insertion mutations in ORFs 17, 29, 56 and 60 with Oka vaccine strains and some clinical strains. Conclusions The Korean VZV vaccine strain SuduVax is genetically similar to the Oka vaccine strains. Further comparative genomic and bioinformatics analyses will help to elucidate the molecular basis of the attenuation of the VZV vaccine strains.

    Full Text Available Simian varicella virus (SVV, the etiologic agent of naturally occurring varicella in primates, is genetically and antigenically closely related to human varicella zoster virus (VZV. Early attempts to develop a model of VZV pathogenesis and latency in nonhuman primates (NHP resulted in persistent infection. More recent models successfully produced latency; however, only a minority of monkeys became viremic and seroconverted. Thus, previous NHP models were not ideally suited to analyze the immune response to SVV during acute infection and the transition to latency. Here, we show for the first time that intrabronchial inoculation of rhesus macaques with SVV closely mimics naturally occurring varicella (chickenpox in humans. Infected monkeys developed varicella and viremia that resolved 21 days after infection. Months later, viral DNA was detected only in ganglia and not in non-ganglionic tissues. Like VZV latency in human ganglia, transcripts corresponding to SVV ORFs 21, 62, 63 and 66, but not ORF 40, were detected by RT-PCR. In addition, as described for VZV, SVV ORF 63 protein was detected in the cytoplasm of neurons in latently infected monkey ganglia by immunohistochemistry. We also present the first in depth analysis of the immune response to SVV. Infected animals produced a strong humoral and cell-mediated immune response to SVV, as assessed by immunohistology, serology and flow cytometry. Intrabronchial inoculation of rhesus macaques with SVV provides a novel model to analyze viral and immunological mechanisms of VZV latency and reactivation.

    Introduction: Imaging of gene expression with positron emission tomography (PET) has emerged as a powerful tool for biomedical research during the last decade. The prototypical herpes simplex virus type 1 thymidine kinase (HSV1-TK) PET reporter gene (PRG) is widely used and many other PRGs have also been validated. We investigated varicella zoster virus thymidine kinase (VZV-tk) as new PRG with radiolabeled bicyclic nucleoside analogues (BCNAs) as PET tracers. Methods: The uptake and washout of four different radiolabeled BCNAs was evaluated in cells expressing VZV-tk after lentiviral vector (LV) transduction and in control cells. Metabolism of the tracers was assayed by high pressure liquid chromatography (HPLC). Mice bearing VZV-TK expressing xenografts were imaged with PET. Results: High uptake in VZV-tk expressing cells was seen for 3 of the 4 tracers tested. The uptake of the tracers could be blocked by the presence of excess thymidine in the incubation solution. Cellular retention was variable, with one tracer showing an acceptable half-life of ∼ 1 hour. The amount of intracellular tracer correlated with the titer of LV used to transduce the cells. VZV-TK dependent conversion into metabolites was shown by HPLC. No specific accumulation was observed in cells expressing a fusion protein containing an HSV1-TK moiety. VZV-tk expression in xenografts resulted in a 60% increase in uptake in vivo as measured with PET. Conclusions: We have validated the combination of VZV-tk and radiolabeled BCNAs as new PRG/PRP system. Further optimization of the PRPs and the PRG are warranted to increase the signal.

  20. Ultra-violet radiation is responsible for the differences in global epidemiology of chickenpox and the evolution of varicella-zoster virus as man migrated out of Africa.

    Of the eight human herpes viruses, varicella-zoster virus, which causes chickenpox and zoster, has a unique epidemiology. Primary infection is much less common in children in the tropics compared with temperate areas. This results in increased adult susceptibility causing outbreaks, for example in health-care workers migrating from tropical to temperate countries. The recent demonstration that there are different genotypes of varicella-zoster virus and their geographic segregation into tropical and temperate areas suggests a distinct, yet previously unconsidered climatic factor may be responsible for both the clinical and molecular epidemiological features of this virus infection. Unlike other human herpes viruses, varicella-zoster virus does not require intimate contact for infection to occur indicating that transmission may be interrupted by a geographically restricted climatic factor. The factor with the largest difference between tropical and temperate zones is ultra-violet radiation. This could reduce the infectiousness of chickenpox cases by inactivating virus in vesicles, before or after rupture. This would explain decreased transmissibility in the tropics and why the peak chickenpox incidence in temperate zones occurs during winter and spring, when ultra-violet radiation is at its lowest. The evolution of geographically restricted genotypes is also explained by ultra-violet radiation driving natural selection of different virus genotypes with varying degrees of resistance to inactivation, tropical genotypes being the most resistant. Consequently, temperate viruses should be more sensitive to its effects. This is supported by the observation that temperate genotypes are found in the tropics only in specific circumstances, namely where ultra-violet radiation has either been excluded or significantly reduced in intensity. The hypothesis is testable by exposing different virus genotypes to ultra-violet radiation and quantifying virus survival by plaque forming

    Full-length genome analysis of varicella-zoster virus (VZV) has shown that viral strains can be classified into seven different genotypes: European (E), Mosaic (M), and Japanese (J), and the E and M genotypes can be further subclassified into E1, E2, and M1 through 4, respectively. The distribution of the main VZV genotypes in Mexico was described earlier, demonstrating the predominance of E genotype, although other genotypes (M1 and M4) were also identified.

    Full Text Available Abstract Background Infection with varicella-zoster virus (VZV contemporaneously with malignant disease or immunosuppression represents a particular challenge and requires individualized decisions and treatment. Although the increasing use of varicella-vaccines in the general population and rapid initiation of VZV-immunoglobulins and acyclovir in case of exposure has been beneficial for some patients, immunocompromised individuals are still at risk for unfavourable courses. Methods In this single center, 6-year analysis we review incidence, hospitalization and complication rates of VZV-infections in our center and compare them to published data. Furthermore, we report three instructive cases. Results Hospitalization rate of referred children with VZV-infections was 45%, among these 17% with malignancies and 9% under immunosuppressive therapy. Rate of complications was not elevated in these two high-risk cohorts, but one ALL-patient died due to VZV-related complications. We report one 4-year old boy with initial diagnosis of acute lymphoblastic leukemia who showed a rapidly fatal outcome of his simultaneous varicella-infection, one 1.8-year old boy with an identical situation but a mild course of his disease, and an 8.5-year old boy with a steroid-dependent nephrotic syndrome. This boy developed severe hepatic involvement during his varicella-infection but responded to immediate withdrawl of steroids and administration of acyclovir plus single-dose cidofovir after nonresponse to acyclovir after 48 h. Conclusion Our data show that patients with malignant diseases or immunosuppressive therapy should be hospitalized and treated immediately with antiviral agents. Despite these measures the course of VZV-infections can be highly variable in these patients. We discuss aids to individual decision-making for these difficult situations.

  3. Is ultra-violet radiation the main force shaping molecular evolution of varicella-zoster virus?

    2011-01-01

    Background Varicella (chickenpox) exhibits a characteristic epidemiological pattern which is associated with climate. In general, primary infections in tropical regions are comparatively less frequent among children than in temperate regions. This peculiarity regarding varicella-zoster virus (VZV) infection among certain age groups in tropical regions results in increased susceptibility during adulthood in these regions. Moreover, this disease shows a cyclic behavior in which the number of cases increases significantly during winter and spring. This observation further supports the participation of environmental factors in global epidemiology of chickenpox. However, the underlying mechanisms responsible for this distinctive disease behavior are not understood completely. In a recent publication, Philip S. Rice has put forward an interesting hypothesis suggesting that ultra-violet (UV) radiation is the major environmental factor driving the molecular evolution of VZV. Discussion While we welcomed the attempt to explain the mechanisms controlling VZV transmission and distribution, we argue that Rice's hypothesis takes lightly the circulation of the so called "temperate VZV genotypes" in tropical regions and, to certain degree, overlooks the predominance of such lineages in certain non-temperate areas. Here, we further discuss and present new information about the overwhelming dominance of temperate VZV genotypes in Mexico regardless of geographical location and climate. Summary UV radiation does not satisfactorily explain the distribution of VZV genotypes in different tropical and temperate regions of Mexico. Additionally, the cyclic behavior of varicella does not shown significant differences between regions with different climates in the country. More studies should be conducted to identify the factors directly involved in viral spreading. A better understanding of the modes of transmissions exploited by VZV and their effect on viral fitness is likely to facilitate

    To determine varicella-zoster virus (VZV) immunity among healthcare workers (HCWs). Cross-sectional study. HCWs attending voluntary periodic health examinations between June 2008 and December 2010. Six public hospitals and five primary care areas in Catalonia, Spain. A self-administered questionnaire was given to eligible HCWs. Variables including age, sex, professional category, type of centre, history of varicella infection, and VZV vaccination were collected. The study was carried out using a convenience sample. The prevalence of antibodies and positive and negative predictive values (PPV and NPV) of the history of clinical VZV infection or vaccination were calculated. Crude and adjusted odds ratios (OR and ORa) and their 95% confidence intervals (CI) were calculated to determine the variables associated with antibody prevalence. Of 705 HCWs who agreed to participate, 644 were finally included. The overall prevalence of antibodies to varicella was 94.9% (95% CI: 92.9-96.4). Of the variables studied, only age was associated with serological susceptibility to VZV. HCWs aged 25-35 years had the highest serological susceptibility (8.1%, 95% CI: 4.6-13.0). The prevalence of antibodies was 96% in subjects reporting previous VZV infection or vaccination, compared with 93% in subjects who did not report these states or did not know. The high proportion of serologically-susceptible HCWs found in this study indicates the need to develop for screening and vaccination strategies in Catalonia. Due to the high capacity of propagation of the VZV in health settings and its consequences, VZV vaccination programmes in HCWs should be reinforced. Copyright © 2014 Elsevier Ltd.

    Varicella-zoster virus (VZV) is highly cell associated when grown in culture and has a much higher (4,000- to 20,000-fold increased) particle-to-PFU ratio in vitro than herpes simplex virus (HSV). In contrast, VZV is highly infectious in vivo by airborne transmission. Neurons are major targets for VZV in vivo ; in neurons, the virus can establish latency and reactivate to produce infectious virus. Using neurons derived from human embryonic stem cells (hESC) and cell-free wild-type (WT) VZV, we demonstrated that neurons are nearly 100 times more permissive for WT VZV infection than very-early-passage human embryonic lung cells or MRC-5 diploid human fibroblasts, the cells used for vaccine production or virus isolation. The peak titers achieved after infection were ∼10-fold higher in human neurons than in MRC-5 cells, and the viral genome copy number-to-PFU ratio for VZV in human neurons was 500, compared with 50,000 for MRC-5 cells. Thus, VZV may not necessarily have a higher particle-to-PFU ratio than other herpesviruses; instead, the cells previously used to propagate virus in vitro may have been suboptimal. Furthermore, based on electron microscopy, neurons infected with VZV produced fewer defective or incomplete viral particles than MRC-5 cells. Our data suggest that neurons derived from hESC may have advantages compared to other cells for studies of VZV pathogenesis, for obtaining stocks of virus with high titers, and for isolating VZV from clinical specimens. IMPORTANCE Varicella-zoster virus (VZV) causes chickenpox and shingles. Cell-free VZV has been difficult to obtain, both for in vitro studies and for vaccine production. While numerous cells lines have been tested for their ability to produce high titers of VZV, the number of total virus particles relative to the number of viral particles that can form plaques in culture has been reported to be extremely high relative to that in other viruses. We show that VZV grows to much higher titers in human

    To analyze the clinical presentation and complications of varicella zoster virus (VZV) infection in children with rheumatic diseases treated with immunosuppressive medication such as biological disease-modifying antirheumatic drugs (bDMARDs) and/or conventional disease-modifying antirheumatic drugs (cDMARDs), and to analyze the therapeutic approach to VZV infections with respect to the concomitant immunosuppressive treatment. Retrospective multicenter study using the Swiss Pediatric Rheumatology registry. Children with rheumatic diseases followed in a Swiss center for pediatric rheumatology and treated with cDMARD and/or bDMARD with a clinical diagnosis of varicella or herpes zoster between January 2004 and December 2013 were included. Twenty-two patients were identified, of whom 20 were treated for juvenile idiopathic arthritis, 1 for a polyglandular autoimmune syndrome type III, and 1 for uveitis. Of these 22 patients, 16 had varicella and 6 had herpes zoster. Median age at VZV disease was 7.6 years (range 2 to 17 years), with 6.3 years (range 2 to 17 years) for those with varicella and 11.6 years (range 5 to 16 years) for those with herpes zoster. The median interval between start of immunosuppression and VZV disease was 14.1 months (range 1 to 63 months). Two patients had received varicella vaccine (1 dose each) prior to start of immunosuppression. Concomitant immunosuppressive therapy was methotrexate (MTX) monotherapy (n = 9) or bDMARD monotherapy (n = 2), or a combination of bDMARD with prednisone, MTX or Leflunomide (n = 11). Four patients experienced VZV related complications: cellulitis in 1 patient treated with MTX, and cellulitis, sepsis and cerebellitis in 3 patients treated with biological agents and MTX combination therapy. Six children were admitted to hospital (range of duration: 4 to 9 days) and 12 were treated with valaciclovir or aciclovir. The clinical course of varicella and herpes zoster in children under

    We estimated the seroprevalences of varicella-zoster virus (VZV), herpes simplex virus (HSV) and cytomegalovirus (CMV) in this cross-sectional database study. Serum samples collected during the National Health and Nutrition survey (ENSANUT 2006) were obtained from subjects aged 1-70 years between January and October 2010. Serological assays for the determination of antibodies against VZV, HSV and CMV were performed. The overall seroprevalences of VZV, HSV-1, HSV-2 and CMV were 85.8%, 80.9%, 9.9% and 89.2%, respectively. Seroprevalences of VZV, HSV-1 and CMV were comparable between males and females. For HSV-2, although the seroprevalence rate was higher in females when compared to males, this difference in seroprevalence was not statistically significant. Seroprevalence rates for VZV, HSV-1, HSV-2 and CMV increased with age (p-value<.0001). Differences in seroprevalence rate for VZV by socioeconomic status (SES) were significant (p-value<0001). Results of the serological analyses reported high VZV seroprevalence, indicating high transmission in the Mexican population with children and adolescents at risk of acquiring VZV. Global HSV-1 seroprevalence was high, especially in adults. HSV-1 and HSV-2 seroprevalences were consistently higher in women than men, particularly for HSV-2. CMV seroprevalence was higher in Mexico when compared to developed countries. Seroepidemiological data on VZV supports the fact that varicella vaccination may serve as an alternative effective solution to reduce transmission in the Mexican population. For CMV and HSV, since no vaccines are available, activities to reduce transmission are important to reduce the risk of complications and therefore need to be considered.

    Full Text Available History of present illness: A 26-year-old male presented to the emergency department with a burning rash over his left axilla and chest that started 2 days prior to presentation. The pain had been steadily worsening and was exacerbated by touch and the rubbing of his clothes over it. Patient denied fevers, chills, or weakness. Patient denied any past medical history, past surgical history or medications. He was unsure of his vaccination history and endorsed having chicken pox as a child. Significant findings: The patient was in mild distress, afebrile, with stable vital signs. His physical exam revealed an erythematous, grouped vesicular rash in various stages of progression including erythematous papules, clear vesicles, and pustular vesicles. Few lesions were scabbed over. No signs of crusting or scarring were appreciated. The distribution encompassed the entire left T4 dermatome both posteriorly and anteriorly. No other rashes were appreciated elsewhere on the body. Discussion: Herpes Zoster (HZ, also known as “shingles,” is a result of the reactivation Varicella Zoster Virus (VZV that emerges from latency in the sensory dorsal root ganglion. The reactivation causes the spreading of a classic rash of group vesicular lesions in various stages along the unilateral sensory dermatomal distribution over the first 3 days. Ulceration and crusting begin to occur after 3-5 days.1 The diagnosis is usually made clinically; however PCR testing of skin lesions is also available to differentiate between VZV, HSV1, and HSV2.2 The incidence of HZ increases with age due to immunosenesacence of cell mediated immunity, with the mean age between 43 and 53 years old.3 An immunocompromised state, due to factors like human immunodeficiency virus (HIV, medications, and autoimmune disease, also increases the incidence of HZ.4-6 A routine HIV screening in this patient was negative. He was prescribed oral acyclovir 800 mg, five times per day for five days.

    Full Text Available Herpes zoster is a common infection caused by the human herpes virus 3, the same virus that causes chickenpox. It is a member of herpes viridae, the same family as the herpes simplex virus, Epstein- Barr virus, and cytomegalovirus. Herpes zoster ophthalmicus occurs when a latent varicella zoster virus in the trigeminal ganglia involving the ophthalmic division of the nerve is reactivated. Of the three divisions of the fifth cranial nerve, the ophthalmic is involved 20 times more frequently than the other divisions.

    2011-12-01

    Full Text Available Varicella-zoster virus (VZV meningoencephalomyelitis is a rare but severe neurological complication of VZV reactivation in immunocompromised patients. We report the case of an HIV-infected individual who developed an acute and severe meningoencephalomyelitis accompanied by a disseminated cutaneous eruption due to VZV. The presence of VZV DNA in cerebrospinal fluid was confirmed by polymerase chain reaction (PCR technique. The patient started undergoing an intravenous acyclovir therapy with a mild recovery of neurological manifestations. Varicella-zoster virus should be included as a cause of acute meningoencephalomyelitis in patients with AIDS. Early diagnosis followed by specific therapy should modify the rapid and fulminant course for this kind of patients.

  16. Use of λgt11 to isolate genes for two pseudorabies virus glycoproteins with homology to herpes simplex virus and varicella-zoster virus glycoproteins

    1986-01-01

    A library of pseudorabies virus (PRV) DNA fragments was constructed in the expression cloning vector λgt11. The library was screened with antisera which reacted with mixtures of PRV proteins to isolate recombinant bacteriophages expressing PRV proteins. By the nature of the λgt11 vector, the cloned proteins were expressed in Escherichia coli as β-galactosidase fusion proteins. The fusion proteins from 35 of these phages were purified and injected into mice to raise antisera. The antisera were screened by several different assays, including immunoprecipitation of [ 14 C]glucosamine-labeled PRV proteins. This method identified phages expressing three different PRV glycoproteins: the secreted glycoprotein, gX; gI; and a glycoprotein that had not been previously identified, which we designate gp63. The gp63 and gI genes map adjacent to each other in the small unique region of the PRV genome. The DNA sequence was determined for the region of the genome encoding gp63 and gI. It was found that gp63 has a region of homology with a herpes simplex virus type 1 (HSV-1) protein, encoded by US7, and also with varicella-zoster virus (VZV) gpIV. The gI protein sequence has a region of homology with HSV-1 gE and VZV gpI. It is concluded that PRV, HSV, and VZV all have a cluster of homologous glycoprotein genes in the small unique components of their genomes and that the organization of these genes is conserved

    The varicella-zoster virus major transactivator, IE62, contains a potent N-terminal acidic transcriptional activation domain (TAD). Our experiments revealed that the minimal IE62 TAD encompasses amino acids (aa) 19 to 67. We showed that the minimal TAD interacts with the human Mediator complex. Site-specific mutations revealed residues throughout the minimal TAD that are important for both activation and Mediator interaction. The TAD interacts directly with aa 402 to 590 of the MED25 subunit,...

    Full Text Available OBJECTIVE: We investigated the relationship of the Herpesviridiae with inflammation and subclinical atherosclerosis in HIV-infected patients. METHODS: Prospective study including virologically suppressed HIV-infected patients. IgG antibodies against herpesviruses, carotid intima-media thickness (cIMT, endothelial function through flow-mediated dilatation (FMD of the brachial artery, and blood atherosclerosis biomarkers (hsCRP, TNF-α, IL-6, MCP-1, MDA, sCD14, sCD163, VCAM-1, ICAM-1, D-dimer, and PAI-1 were measured. RESULTS: 136 patients with HIV viral load <200 copies/ml were included. 93.4% patients were infected with herpes simplex virus type-1, 55.9% with herpes simplex virus type-2, 97.1% with varicella-zoster virus, 65.4% with human herpesvirus-6, 91.2% with cytomegalovirus, and 99.3% with Epstein-Barr virus. Previous AIDS diagnosis was associated with higher cytomegalovirus IgG titers (23,000 vs 17,000 AU, P = 0.011 and higher varicella-zoster virus IgG titers (3.19 vs 2.88 AU, P = 0.047, and there was a positive correlation of the Framingham risk score with IgG levels against cytomegalovirus (Spearman's Rho 0.216, P = 0.016 and Herpes simplex virus-2 (Spearman's Rho 0.293, P = 0.001. IgG antibodies against cytomegalovirus correlated in adjusted analysis with the cIMT (P = 0.030. High seropositivity for varicella-zoster virus (OR 2.91, 95% CI 1.05-8.01, P = 0.039, and for cytomegalovirus (OR 3.79, 95% CI 1.20-11.97, P = 0.023 were predictors for the highest quartile of the cIMT in adjusted analyses. PAI-1 levels were independently associated with cytomegalovirus IgG titers (P = 0.041, IL-6 and ICAM-1 levels with varicella-zoster virus IgG (P = 0.046 and P = 0.035 respectively, and hsCRP levels with Herpes simplex virus-2 IgG (P = 0.035. CONCLUSION: In virologically suppressed HIV-infected patients, antibody responses against herpesviruses are associated with subclinical atherosclerosis, and with increased inflammation and coagulation

    Varicella-zoster virus (VZV), a herpesvirus, is a ubiquitous organism that causes considerable morbidity worldwide and can cause severe complications on reactivation. Phylogenetic analysis was performed on 19 clinical VZV isolates (16 zoster and 3 varicella) found in Ireland, between December 2006 and November 2008, in order to determine whether previously reported viral heterogeneity was still present and whether viral recombination was evident. Open reading-frames (ORFs) from genes 1, 21, 50, and 54, were sequenced. Clades 1, 2, 3, and 5 were identified. Four putative recombinant isolates were detected (three clade 3\\/1 and one clade 5\\/3\\/1). Further sequencing and examination of ORF 22 and 21\\/50, did not elucidate the putative recombinant genotypes further. These two previously published genotyping schemes were examined in light of the new consensus genotyping scheme proposed in 2010. Remarkable VZV heterogeneity remains prevalent in Ireland. This is the first evidence of putative VZV recombination found in Ireland.

    Varicella- zoster virus infection is an intriguing medical entity that involves many medical specialties including infectious diseases, immunology, dermatology, and neurology. It can affect patients from early childhood to old age. Its treatment requires expertise in pain management and psychological support. While varicella is caused by acute viremia, herpes zoster occurs after the dormant viral infection, involving the cranial nerve or sensory root ganglia, is re-activated and spreads orthodromically from the ganglion, via the sensory nerve root, to the innervated target tissue (skin, cornea, auditory canal, etc.). Typically, a single dermatome is involved, although two or three adjacent dermatomes may be affected. The lesions usually do not cross the midline. Herpes zoster can also present with unique or atypical clinical manifestations, such as glioma, zoster sine herpete and bilateral herpes zoster, which can be a challenging diagnosis even for experienced physicians. We discuss the epidemiology, pathophysiology, diagnosis and management of Herpes Zoster, typical and atypical presentations.

    Full Text Available Fingolimod, an oral sphingosine 1-phosphate (S1P receptor modulator, is approved for the treatment of relapsing forms of multiple sclerosis (MS. The interference with S1P signaling leads to retention particularly of chemokine receptor-7 (CCR7 expressing T cells in lymph nodes. The immunological basis of varicella zoster virus (VZV infections during fingolimod treatment is unclear. Here, we studied the dynamics of systemic and intrathecal immune responses associated with symptomatic VZV reactivation including cessation of fingolimod and initiation of antiviral therapy. Key features in peripheral blood were an about two-fold increase of VZV-specific IgG at diagnosis of VZV reactivation as compared to the previous months, a relative enrichment of effector CD4+ T cells (36% versus mean 12% in controls, and an accelerated reconstitution of absolute lymphocytes counts including a normalized CD4+/CD8+ ratio and reappearance of CCR7+ T cells. In cerebrospinal fluid (CSF the lymphocytic pleocytosis and CD4+/CD8+ ratios at diagnosis of reactivation and after nine days of fingolimod discontinuation remained unchanged. During this time CCR7+ T cells were not observed in CSF. Further research into fingolimod-associated VZV reactivation and immune reconstitution is mandatory to prevent morbidity and mortality associated with this potentially life-threatening condition.

    Full-length genome analysis of varicella-zoster virus (VZV) has shown that viral strains can be classified into seven different genotypes: European (E), Mosaic (M), and Japanese (J), and the E and M genotypes can be further subclassified into E1, E2, and M1 through 4, respectively. The distribution of the main VZV genotypes in Mexico was described earlier, demonstrating the predominance of E genotype, although other genotypes (M1 and M4) were also identified. However, no information regarding the circulation of either E genotype in the country is available. In the present study, we confirm the presence of both E1 and E2 genotypes in the country and explore the possibility of coinfection as the triggering factor for increased virulence among severe cases. A total of 61 different European VZV isolates collected in the Mexico City metropolitan area from 2005 to 2006 were typed by using a PCR method based on genotype-specific primer amplification. Fifty isolates belonged to the E1 genotype, and the eleven remaining samples were classified as E2 genotypes. No coinfection with both E genotypes was identified among these specimens. We provide here new information on the distribution of VZV genotypes circulating in Mexico City. PMID:20220168

    Varicella-zoster virus (VZV) glycoprotein gpI is the predominant viral glycoprotein within the plasma membranes of infected cells. This viral glycoprotein is phosphorylated on its polypeptide backbone during biosynthesis. In this report, the authors investigated the protein kinases which participate in the phosphorylation events. Under in vivo conditions, VZV gpI was phosphorylated on its serine and threonine residues by protein kinases present within lysates of either VZV-infected or uninfected cells. Because this activity was diminished by heparin, a known inhibitor of casein kinase II, isolated gpI was incubated with purified casein kinase II and shown to be phosphorylated in an in vitro assay containing [γ- 32 P]ATP. The same glycoprotein was phosphorylated when [ 32 P]GTP was substituted for [ 32 P]ATP in the protein kinase assay. They also tested whether VZV gpI was phosphorylated by two other ubiquitous mammalian protein kinases--casein kinase I and cyclic AMP-dependent kinase--and found that only casein kinase I modified gpI. When the predicted 623-amino-acid sequence of gpI was examined, two phosphorylation sites known to be optimal for casein kinase II were observed. In summary, this study showed that VZV gpI was phosphorylated by each of two mammalian protein kinases (casein kinase I and casein kinase II) and that potential serine-threonine phosphorylation sites for each of these two kinases were present in the viral glycoprotein

    Full Text Available Abstract Introduction The deadly threat of systemic infections with coagulase negative Staphylococcus lugdunensis despite an appropriate antibiotic therapy has only recently been recognized. The predominant infectious focus observed so far is left-sided native heart valve endocarditis, but bone and soft tissue infections, septicaemia and vascular catheter-related bloodstream infections have also been reported. We present a patient with a fatal Staphylococcus lugdunensis septicaemia following zoster bacterial superinfection of the pelvic region. Case presentation A 71-year old male diagnosed with IgG kappa plasmocytoma presented with a conspicuous weight loss, a hypercalcaemic crisis and acute renal failure. After initiation of haemodialysis treatment his condition improved rapidly. However, he developed a varicella-zoster virus infection of the twelfth thoracic dermatome requiring intravenous acyclovir treatment. Four days later the patient presented with a fulminant septicaemia. Despite an early intravenous antibiotic therapy with ciprofloxacin, piperacillin/combactam and vancomycin the patient died within 48 hours, shortly before the infective isolate was identified as Staphylococcus lugdunensis by polymerase chain reaction. Conclusion Despite S. lugdunensis belonging to the family of coagulase-negative staphylococci with an usually low virulence, infections with S. lugdunensis may be associated with an aggressive course and high mortality. This is the first report on a Staphylococcus lugdunensis septicaemia following a zoster bacterial superinfection of the pelvic region.

    Myelitis is one of the rarest neurological complications of the varicella zoster virus (VZV) infection. Focal muscle weakness with or without sensory disturbance occurs in approximately 5% of the cases after acute VZV infection, with complete recovery in 50-70%. This report describes two rare cases of elderly patients with VZV myelitis secondary to dermatomal zoster rash. Patient 1 was a 79-year-old woman who developed paraplegia, numbness and decreased sensation in the left arm and below thoracic (Th)-10 after sacral zoster. Spinal cord MRI showed a high-signal-intensity lesion at the cervical spinal nerve 2 on a T2-weighted image. Patient 2 was a 73-year-old man who developed right flaccid leg weakness and urinary retention after right dorsal Th 5-8 zoster. Spinal cord MRI showed a high-signal-intensity lesion at Th 3-4 on a T2-weighted image. In both cases, although the conventional single polymerase chain reaction (PCR) assays all showed negative results, the original nested PCR assay detected VZV DNA in the cerebrospinal fluid (CSF) specimen collected on admission. In addition, the anti-VZV IgG antibody by enzyme immunoassay and antibody index were elevated in the CSF specimens during the clinical courses of both patients. On the basis of these findings, both patients were diagnosed with VZV myelitis and were treated with high-dose acyclovir and corticosteroid. This combined treatment was appropriate and effective for the improvement of their functional outcomes. The detection of VZV DNA in CSF by nested PCR assay and the evaluation of the antibody index to VZV had significant diagnostic value.

Moreover, the onset rate of herpes zoster with urinary dysfunction is 0.6%1). The lesion sites of herpes zoster which cause urinary dysfunction are almost lumber and sacral areas. We describe four cases of sacral herpes zoster with urinary dysfunction in this report. All patients were elderly people (66-84 years old), and all patients were administered anti-virus drugs and alpha 1-adrenergic receptor blockers. Because of urinary retention, three patients have performed clean intermittent self-catheterization (CIC) for several weeks. As the lesions of herpes zoster healed, each patient recovered from urinary dysfunction.

    To determine the risks associated with zoster vaccine when administered to patients taking immunosuppressant medications. Patients enrolled in 1 of 7 managed care organizations affiliated with the Vaccine Safety Datalink between January 1, 2006, and December 31, 2009, were eligible. The exposure of interest was zoster vaccination in patients with current or remote immunosuppressant drug use. The primary outcomes were disseminated varicella zoster virus (VZV) and herpes zoster in the 42 days after vaccination. Automated data were collected on immunosuppressant drugs and baseline medical conditions. A logistic regression model using inverse probability treatment weights was used to estimate the odds of developing VZV or herpes zoster. A total of 14,554 individuals had an immunosuppressant medication dispensed around the time of vaccination, including 4826 with current use and 9728 with remote use. Most patients were taking low-dose corticosteroids. No cases of disseminated VZV were found in the current or remote users. The risk of herpes zoster was elevated in the 42 days after vaccination in current vs remote users (adjusted odds ratio, 2.99; 95% CI, 1.58-5.70). We found that patients taking immunosuppressant medications at the time of vaccination had a modest increased risk of herpes zoster in the 42 days after vaccination. The development of herpes zoster within 42 days after vaccination suggests that this is more likely due to reactivation of latent zoster virus than dissemination of the vaccine-derived varicella virus. These findings support the current zoster vaccination guidelines. Copyright © 2015 Mayo Foundation for Medical Education and Research. All rights reserved.

    Herpes zoster and an associated complication, postherpetic neuralgia, are both attributable to the varicella zoster virus. This virus, which lies dormant within the affected sensory ganglia after an initial infection, appears to be triggered in part by a decrease in immunity. According to available research, stress, stressful life events, and depressive symptoms are identified antecedents to outbreaks of herpes zoster. Likewise, the development of postherpetic neuralgia has been associated wi...

    A systematic screening for measles, mumps, rubella (MMR) and varicella zoster virus (VZV) in HIV-positive adult immigrants in Spain was evaluated, and factors associated with MMR and VZV vaccines' indication were studied. Every HIV-positive immigrant was tested for VZV and MMR-IgG. MMR vaccine was indicated to patients with lymphocytes CD4+ >200 cells/mm³ and a negative measles-IgG, a negative mumps-IgG and/or a negative rubella-IgG. VZV vaccine was indicated to every VZV-IgG negative patient with CD4+ >400 cells/mm³. In total, 289 patients were screened; seroprevalence was 95.2%, 92.2%, 70.3% and 89.3% for VZV, measles, mumps and rubella IgG, respectively. Having a negative VZV-IgG was statistically associated with coming from sub-Saharan Africa (prevalence ratio [PR]: 6.52; 95% CI: 1.71-24.84; p=0.006), while having secondary education was a protective factor (PR: 0.25; 95% CI: 0.07-0.97; p=0.045). Fourteen patients (4.8%) had indication of VZV vaccine; vaccination was feasible in 21.4% of them at first visit. Eighty-one patients (29.7%) had indication of MMR vaccine, most of them due to mumps-IgG negative (53.1%) or rubella-IgG negative (24.7%). Age Especial attention should be given to immigrant women of childbearing age.

  12. The natural history of varicella zoster virus infection in Norway: Further insights on exogenous boosting and progressive immunity to herpes zoster.

    Directory of Open Access Journals (Sweden)

    Luigi Marangi

    Full Text Available We use age-structured models for VZV transmission and reactivation to reconstruct the natural history of VZV in Norway based on available pre-vaccination serological data, contact matrices, and herpes zoster incidence data. Depending on the hypotheses on contact and transmission patterns, the basic reproduction number of varicella in Norway ranges between 3.7 and 5.0, implying a vaccine coverage between 73 and 80% to effectively interrupt transmission with a 100% vaccine efficacy against infection. The varicella force of infection peaks during early childhood (3-5 yrs and shows a prolonged phase of higher risk during the childbearing period, though quantitative variations can occur depending on contact patterns. By expressing the magnitude of exogenous boosting as a proportion of the force of infection, it is shown that reactivation is well described by a progressive immunity mechanism sustained by a large, though possibly below 100%, degree of exogenous boosting, in agreement with findings from other Nordic countries, implying large reproduction numbers of boosting. Moreover, magnitudes of exogenous boosting below 40% are robustly disconfirmed by data. These results bring further insight on the magnitude of immunity boosting and its relationship with reactivation.

    Herpes zoster is a major health burden that can affect individuals of any age. It is seen more commonly among individuals aged ≥50 years, those with immunocompromised status, and those on immunosuppressant drugs. It is caused by a reactivation of varicella zoster virus infection. Cell-mediated immunity plays a role in this reactivation. Fever, pain, and itch are common symptoms before the onset of rash. Post-herpetic neuralgia is the most common complication associated with herpes zoster. Risk factors and complications associated with herpes zoster depend on the age, immune status, and the time of initializing treatment. Routine vaccination for individuals over 60 years has shown considerable effect in terms of reducing the incidence of herpes zoster and post-herpetic neuralgia. Treatment with antiviral drugs and analgesics within 72 hours of rash onset has been shown to reduce severity and complications associated with herpes zoster and post-herpetic neuralgia. This study mainly focuses on herpes zoster using articles and reviews from PubMed, Embase, Cochrane library, and a manual search from Google Scholar. We cover the incidence of herpes zoster, gender distribution, seasonal and regional distribution of herpes zoster, incidence of herpes zoster among immunocompromised individuals, incidence of post-herpetic neuralgia following a zoster infection, complications, management, and prevention of herpes zoster and post-herpetic neuralgia.

It forms polynuclear syncytia in culture, in varicella skin lesions and in infected fetal human ganglia xenografted to mice. After axonal infection using VZV expressing green fluorescent protein (GFP) in compartmentalized microfluidic cultures there is diffuse filling of axons with GFP as well as punctate fluorescence corresponding to capsids. Use of viruses with fluorescent fusions to VZV proteins reveals that both proteins encoded by VZV genes and those of the infecting cell are transferred in bulk from infecting non-neuronal cells to axons. Similar transfer of protein to axons was observed following cell associated HSV1 infection. Fluorescence recovery after photobleaching (FRAP) experiments provide evidence that this transfer is by diffusion of proteins from the infecting cells into axons. Time-lapse movies and immunocytochemical experiments in co-cultures demonstrate that non-neuronal cells fuse with neuronal somata and proteins from both cell types are present in the syncytia formed. The fusogenic nature of VZV therefore may enable not only conventional entry of virions and capsids into axonal endings in the skin by classical entry mechanisms, but also by cytoplasmic fusion that permits viral protein transfer to neurons in bulk.

    Two vaccines against varicella-zoster virus are available in France. These live attenuated vaccines are derived from the Oka strain used in Japan since 1974. They are indicated for healthy subjects from 12 months of age, at a dose of one injection until 12 years of age, and two injections 4-8 weeks apart for older children and adults. Seroconversion occurs in 95% of cases and the antibodies persist beyond 5 years. Clinical efficacy is about 85% against all forms of varicella and nearly 100% against severe forms. Post-exposure vaccination within 3 days may also prevent the disease. A universal immunization program against varicella was implemented in the USA in 1995. Now, with vaccine coverage at about 80%, the incidence of the disease has been reduced by 85%, with the largest decrease in 1- to 4-year-olds. Tolerability is generally good, with only mild reactions at the injection site and moderate fever The length of protection is not yet known. A two-dose schedule seems advisable to avoid breakthrough varicella, which occurs in 4% of vaccinees each year. Insufficient coverage is expected to lead to later disease onset, with more severe cases in adolescents and adults. Universal immunization could also increase the incidence of zoster. These problems indeed seem to be emerging in the United States. France has adopted restrictive guidelines on VZV vaccination, but they are expected to be revised when the combined MMR-V vaccine becomes available. Zoster vaccine, prepared with the same strain but at a higher concentration, has moderate efficacy on zoster and on post-zoster neuralgia in patients over 70. This vaccine is not yet recommended in France, because the length of protection is not known and there is a potential risk of delaying the occurrence of zoster and, thus, of increasing the risk of post zoster neuralgia.

    to carry glycans, little is known about the distribution, nature, and functions of these modifications. This is particularly true for O-glycans; thus we have recently developed a "bottom up" mass spectrometry-based technique for mapping O-glycosylation sites on herpes simplex virus type 1. We found wide...... distribution of O-glycans on herpes simplex virus type 1 glycoproteins and demonstrated that elongated O-glycans were essential for the propagation of the virus. Here, we applied our proteome-wide discovery platform for mapping O-glycosites on representative and clinically significant members...

    Herpes zoster or shingles is reactivation of the varicella zoster virus that had entered the cutaneous nerve endings during an earlier episode of chicken pox traveled to the dorsal root ganglia and remained in a latent form. This condition is characterized by occurrence of multiple, painful, unilateral vesicles and ulceration which shows a typical single dermatome involvement. In this case report, we present a patient with herpes zoster involving the mandibular division of the trigeminal nerve, with unilateral vesicles over the right side of lower third of face along the trigeminal nerve tract, with intraoral involvement of buccal mucosa, labial mucosa and the tongue of the same side. Cytopathology revealed classic features of herpes infection including inclusion bodies, perinuclear halo and multinucleated cells.

    A real-time PCR assay was developed to identify varicella-zoster virus (VZV) and herpes simplex virus (HSV) DNA in clinical specimens from subjects with suspected herpes zoster (HZ; shingles). Three sets of primers and probes were used in separate PCR reactions to detect and discriminate among wild-type VZV (VZV-WT), Oka vaccine strain VZV (VZV-Oka), and HSV DNA, and the reaction for each virus DNA was multiplexed with primers and probe specific for the human β-globin gene to assess specimen adequacy. Discrimination of all VZV-WT strains, including Japanese isolates and the Oka parent strain, from VZV-Oka was based upon a single nucleotide polymorphism at position 106262 in ORF 62, resulting in preferential amplification by the homologous primer pair. The assay was highly sensitive and specific for the target virus DNA, and no cross-reactions were detected with any other infectious agent. With the PCR assay as the gold standard, the sensitivity of virus culture was 53% for VZV and 77% for HSV. There was 92% agreement between the clinical diagnosis of HZ by the Clinical Evaluation Committee and the PCR assay results. PMID:19475609

    The first step of herpesviruses virion assembly occurs in the nucleus. However, the exact site where nucleocapsids are assembled, where the genome and the inner tegument are acquired, remains controversial. We created a recombinant VZV expressing ORF23 (homologous to HSV-1 VP26) fused to the eGFP and dually fluorescent viruses with a tegument protein additionally fused to a red tag (ORF9, ORF21 and ORF22 corresponding to HSV-1 UL49, UL37 and UL36). We identified nuclear dense structures containing the major capsid protein, the scaffold protein and maturing protease, as well as ORF21 and ORF22. Correlative microscopy demonstrated that the structures correspond to capsid aggregates and time-lapse video imaging showed that they appear prior to the accumulation of cytoplasmic capsids, presumably undergoing the secondary egress, and are highly dynamic. Our observations suggest that these structures might represent a nuclear area important for capsid assembly and/or maturation before the budding at the inner nuclear membrane. - Highlights: • We created a recombinant VZV expressing the small capsid protein fused to the eGFP. • We identified nuclear dense structures containing capsid and procapsid proteins. • Correlative microscopy showed that the structures correspond to capsid aggregates. • Procapsids and partial capsids are found within the aggregates of WT and eGFP-23 VZV. • FRAP and FLIP experiments demonstrated that they are dynamic structures.

    Zona zoster infection is often associated with painful erythematous vesicular eruptions of the skin or mucous membranes. Varicella zoster virus which stays latent in the sensorial root ganglia causes zona zoster infection. The most recognized feature of zona zoster is the dermatomal distribution of vesicular rashes. In the present case report, we state an unusual presentation of sacral zona zoster with urinary retention, erectile dysfunction and meningitis. Copyright 2009 S. Karger AG, Basel.

    Full Text Available A serosurvey of varicella has been carried out in children attending the public school network of São Paulo city, Brazil, from 1992 to 1994. This study was performed in order to establish the age related prevalence of antibodies against varicella-zoster virus (VZV and its age specific transmission dynamics pattern in these children. Among 2500 schools in the city of São Paulo public network, 304 were randomly selected; 7 children of a given age (ranging from 1 to 15 years were randomly selected in each school, and blood samples were obtained by fingerprick into filter paper. Blood eluates were analyzed for the presence of antibodies to VZV by ELISA. Proportion of seropositivity were calculated for each age group. Samples consisted of 1768 individuals in 1992, 1758 in 1993, and 1817 in 1994, resulting in 5343 eluates. A high proportion of seropositive children from 1 to 3 years of age was observed, ascending until 10 years of age and reaching a plateau around 90% afterwards. VZV transmission in this community was similar along the three years of the study. In children attending public schools in the city of São Paulo, contact with VZV occurs in early childhood. If immunization against VZV is considered it should be introduced as soon as possible.Um estudo sorológico para varicela foi realizado em crianças matriculadas na rede pública de ensino da cidade de São Paulo, Brasil, entre 1992 e 1994.

    Although congenital varicella-zoster virus VZV infection is rare, it carries serious morbidity and mortality to the fetus and newborn infant. We report a full term female newborn infant, born to a multipara unbooked mother who had VZV subclinical infection during the first trimester of pregnancy. Routine newborn examination showed cystic malformation of the left eye, and absence of the right eye globe. Radiological work up revealed severe brain and eye malformations, serological studies of both mother and baby were positive for VZV. The baby underwent palliative surgery to the eyes, upon discharge, a plan of multidisciplinary team was made for follow up including neurologist, ophthalmologist, pediatrician and social worker. Congenital VZV infection can be severe enough to cause catastrophic fetal anomalies and damage to the vital organs as many of those infants die in infancy. (author)

    To examine the current seroepidemiology of immunoglobulin (Ig)G for herpes simplex virus types 1 and 2 (HSV 1-2), varicella zoster virus (VZV), and cytomegalovirus (CMV) among university females of childbearing age in Syria. A cross-sectional study was conducted to examine the female students of the Pharmacy College, Kalamoon University, Deratiah, Syria, where 316 sera were collected from October 2009 to November 2010, and subjected to HSV 1-2, VZV, and CMV IgG screening and titration using enzyme-linked immunosorbent assay-based techniques in the Microbiology Laboratory. A total of 164 participants were positive for HSV 1-2 IgG giving a prevalence of 52%, leaving a relatively high proportion of susceptibility among the tested group. For VZV, 91% of the participants (n=287) were positive for its specific IgG, while, regarding CMV, 74.5% (n=235) were positive, and 25.5% were negative for CMV specific IgG. Although most participants were seropositive for herpes viruses IgG, suggesting a natural virus circulation within the community, screening for protective immunity is suggested against HSV, since a relatively high proportion of tested females are still susceptible. In addition, and because of its nasty outcomes during pregnancy, IgG against CMV should also be tested. High percentage of positivity towards VZV could be explained due to introduction of the new vaccine program, and therefore, further analysis during pregnancy is not recommended.

    Of the eight members of the herpes family of viruses, HSV1, HSV2, and varicella zoster are the most common and are mainly involved in cutaneous disorders. These viruses usually are not life-threatening, but in some cases they might cause serious infections to the eyes and the brain that can lead to blindness and possibly death. An effective drug (acyclovir and its derivatives) is available against these viruses. Therefore, early detection and identification of these viral infections is highly important for an effective treatment. Raman spectroscopy, which has been widely used in the past years in medicine and biology, was used as a powerful spectroscopic tool for the detection and identification of these viral infections in cell culture, due to its sensitivity, rapidity and reliability. Our results showed that it was possible to differentiate, with a 97% identification success rate, the uninfected Vero cells that served as a control, from the Vero cells that were infected with HSV-1, HSV-2, and VZV. For that, linear discriminant analysis (LDA) was performed on the Raman spectra after principal component analysis (PCA) with a leave one out (LOO) approach. Raman spectroscopy in tandem with PCA and LDA enable to differentiate among the different herpes viral infections of Vero cells in time span of few minutes with high accuracy rate. Understanding cell molecular changes due to herpes viral infections using Raman spectroscopy may help in early detection and effective treatment.

    Specimens from skin lesions were examined simultaneously for herpes simplex virus (HSV) and varicella-zoster virus (VZV) by direct specimen testing and shell vial culture in single-test systems. For direct testing, cells in a single specimen well were stained with a combination direct-indirect immunofluorescence stain by using two fluorescent tags. A total of 203 fresh specimens were tested in parallel. Of these, 100 specimens contained too few cells for the direct VZV comparison and 91 contained too few cells for the HSV comparison. After these specimens were eliminated, the sensitivities and specificities, respectively, of the dual direct test were 86.1 and 97.3% for HSV compared with single culture and 92.2 and 100% for VZV compared with single direct testing. Shell vial monolayers in the combined cultures were stained for both viruses by the same method. A total of 305 fresh specimens were cultured in parallel by dual- and single-culture methods. The sensitivities and specificities, respectively, of the combined culture compared with separate cultures were 100 and 98.4% for HSV and 87.9 and 99.2% for VZV. The combined methods gave a performance comparable to those of single tests, required less specimen volume, and were less costly to perform.

    Infection with varicella-zoster virus (VZV) rendered RAJI cells more susceptible to lysis by non-adherent blood lymphocytes. At an effector to target ratio of 80:1 the mean percentage of /sup 51/Cr release of VZV-infected RAJI cells was 41 +/- 12%, whereas that of uninfected RAJI cells was 15 +/- 6%. The increased susceptibility to lysis was associated with increased effector to target conjugate formation in immunofluorescence binding assays. The effector cells cytotoxic for VZV-infected RAJI cells were predominantly Leu-11a/sup +/ Leu-4/sup -/ granular lymphocytes as demonstrated by fluorescence-activated cell sorting. The effector cell active against VZV-infected RAJI cells appeared similar to those active against herpes simplex virus (HSV)-infected cells, because in cold target competition experiments the lysis of /sup 51/Cr-labeled VZV-infected RAJI cells was efficiently inhibited by either unlabeled VZV-infected RAJI cells (mean 71% inhibition, 2:1 ratio unlabeled to labeled target) or HSV-infected RAJI cells (mean 69% inhibition) but not by uninfected RAJI cells (mean 10% inhibition). In contrast, competition experiments revealed donor heterogeneity in the overlap between effector cells for VZV- or HSV-infected RAJI vs K-562 cells.

    Herpes simplex viruses (HSV) and varicella zoster virus (VZV) can have very similar and wide-ranging clinical presentations. Rapid identification is necessary for timely antiviral therapy, especially with infections involving the central nervous system, neonates, and immunocompromised individuals. Detection of HSV-1, HSV-2 and VZV was combined into one real-time PCR reaction utilizing hydrolysis probes. The assay was validated on the LightCycler(®) (Roche) and Applied Biosystems 7500 Real-Time PCR System (Thermo Fisher Scientific Inc.) to detect alphaherpesviruses in cerebral spinal fluid (CSF) and lesion swab specimens, respectively. Validation data on blood and tissue samples are also presented. The multiplex assay showed excellent sensitivity, specificity and reproducibility when compared to two singleplex real-time PCR assays for CSF samples and direct fluorescent antigen/culture for lesion swab samples. Implementation of the multiplex assay has facilitated improved sensitivity and accuracy as well as reduced turn-around-times and costs. The results from a large data set of 16,622 prospective samples tested between August 16, 2012 to February 1, 2014 at the Provincial Laboratory for Public Health (Alberta, Canada) are presented here.

Dissemination of herpes zoster is uncommon in immunocompetent individuals. Reports of disseminated herpes zoster in children are even less common than in adults. An unusual case of disseminated herpes zoster ophthalmicus in an 8-year old immunocompetent black boy is presented. He had a previous primary Varicella zoster virus infection at three years of age. In the current report, he presented during an on-going chicken pox outbreak and survived with no significant complications. A breakthrough varicella virus re-infection or a reactivation is possible, both of which could present as zoster. This case emphasizes the need for prevention of varicella virus infection through universal childhood immunization and effective infection control strategies in health care settings.

    The environment of space results in a multitude of challenges to the human physiology that present barriers to extended habitation and exploration. Over 40 years of investigation to define countermeasures to address space flight adaptation has left gaps in our knowledge regarding mitigation strategies partly due to the lack of investigative tools, monitoring strategies, and real time diagnostics to understand the central causative agent(s) responsible for physiologic adaptation and maintaining homeostasis. Spaceflight-adaptation syndrome is the combination of space environmental conditions and the synergistic reaction of the human physiology. Our work addresses the role of oxidative stress and damage (OSaD) as a negative and contributing Risk Factor (RF) in the following areas of combined spaceflight related dysregulation: i) radiation induced cellular damage [1], [2] ii) immune impacts and the inflammatory response [3], [4] and iii) varicella zoster virus (VZV) reactivation [5]. Varicella-zoster (VZV)/Chicken Pox virus is a neurotropic human alphaherpesvirus resulting in varicella upon primary infection, suppressed by the immune system becomes latent in ganglionic neurons, and reactivates under stress events to re-express in zoster and possibly shingles. Our laboratory has developed a complex threedimensional (3D) normal human neural tissue model that emulates several characteristics of the human trigeminal ganglia (TG) and allows the study of combinatorial experimentation which addresses, simultaneously, OSaD associated with Spaceflight adaptation and habitation [6].

    We present a case of reactivated herpes zoster keratouveitis of 6 years duration with corneal perforation requiring penetrating keratoplasty shortly after inoculation with herpes zoster vaccine (Zostavax, Merck, Quebec, Canada). Retrospective case report. A 67-year-old woman with a 5-year history of recurrent unilateral herpes zoster keratouveitis in her right eye presented with another recurrence 2 weeks after Zostavax vaccination. Three months later, she developed descemetocele and 2 months afterward, corneal perforation, which was managed by penetrating keratoplasty. Immunohistopathological examination disclosed positive staining for varicella zoster virus in most of the keratocytes adjacent to the descemetocele and perforation, most vividly in the deeper two-thirds of the stroma where the keratocytes were most dense, but not in corneal epithelium or endothelium. Electron microscopic examination showed universally severely degenerated corneal keratocytes in the corneal stroma adjacent to the perforation with variable numbers of herpes virus capsids present in half of these cells. Only a rare normal-appearing keratocyte was identified in the more peripheral corneal stroma. We present a case of reactivation of herpes keratouveitis shortly after vaccination with Zostavax in a patient with previous herpes zoster ophthalmicus. We demonstrate, for the first time, ultrastructural evidence consistent with inactive virus capsids in diffusely degenerated keratocytes in the extracted corneal tissue.

    A 35-years-old right-handed man admitted to our hospital with a worsening of dysarthria, left facial palsy and left hemiparesis for 2 days. Acquired immunodeficiency syndrome (AIDS) was diagnosed when he was 28 years old. At that time, he also was treated for syphilis. After highly active antiretroviral treatment (HAART) was introduced at the age of 35 years old, serum level of human immunodeficiency virus (HIV) was not detected, but the number of CD4+ T cells was still less than 200/μl. He had no risk factors of atherosclerosis including hypertension, diabetes and hyperlipidemia. He had neither coagulation abnormality nor autoimmune disease. Magnetic resonance imaging (MRI) showed acute ischemic infarction spreading from the right corona radiate to the right internal capsule without contrast enhancement. Stenosis and occlusion of intracranial arteries were not detected by MR angiography. Although argatroban and edaravone were administered, his neurological deficits were worsened to be difficult to walk independently. Cerebrospinal fluid (CSF) examination showed a mild mononuclear pleocytosis (16/μl). Oligoclonal band was positive. The titer of anti-varicella zoster virus (VZV) IgG antibodies was increased, that indicated VZV reactivation in the central nervous system (CNS), although VZV DNA PCR was not detected. Therefore, acyclovir (750 mg/day for 2 weeks) and valaciclovir (3,000 mg/day for 1 month) were administered in addition to stroke therapy. He recovered to be able to walk independently 2 month after the admission.Angiography uncovered a saccular aneurysm of 3 mm at the end of branch artery of right anterior cerebral artery, Heubner artery, 28 days after the admission. We speculated that VZV vasculopathy caused by VZV reactivation in CNS was involved in the pathomechanism of cerebral infarction rather than HIV vasculopathy in the case.

    Susceptibility assays by cell culture methods are time-consuming and are particularly difficult to perform with varicella-zoster virus (VZV). To overcome this limitation, we have adapted a functional test of the viral thymidine kinase (TK) in TK-deficient (tdk mutant) bacteria to detect ACV-resistant VZV in clinical samples. After PCR amplification, the complete viral TK open reading frame (ORF) is purified from PCR primers, digested with two restriction enzymes, and ligated in an oriented fashion into a bacterial expression vector. The ligation products are then used to transform tdk mutant bacteria. After transformation, an aliquot of the bacteria is plated onto a plate with minimal medium containing (i) ampicillin to select for plasmids carrying the viral TK ORF and (ii) isopropyl beta-D-thiogalactopyranoside (IPTG) to induce its expression. An identical aliquot of bacteria is also plated onto a medium containing, in addition to the components described above, 5-fluorodeoxyuridine (FUdR). Compared to the number of transformants on FUdR-free medium, the number of colonies carrying TK derived from susceptible strains was reduced by 86%, on average, in the presence of FUdR. In contrast, the number of transformants carrying TK from resistant strains with a mutant TK were reduced by only 4%, on average, on FUdR-containing plates. We have assessed the validity of this assay with cell culture isolates and several clinical samples including two cerebrospinal fluid samples from which no virus could be isolated. This colony reduction assay allowed the correct identification of the TK phenotype of each VZV isolate tested and can be completed within 3 days of receipt of the sample.

    Herpes zoster is a common viral infection of skin caused by reactivation of varicella zoster virus infection from the spinal ganglia. The clinico-epidemiological patterns of this disease in an Indian setting required to be studied. A cross sectional study was conducted on all consecutive cases of herpes zoster reporting to the Dermatology Outpatient Department at a Tertiary Care Hospital in Bangalore during a period of one year from 01 Jun 2013 to 31 May 2014. Detailed history, examination, HIV screening and Tzanck smear were carried out in all cases. 84 cases of herpes zoster were seen with a mean age of 30 years. Majority (39%) of cases were seen in the 21-30 year age group. Thoracic segments were involved in 65.4%, cervical in 11.9%, cranial in 11.5%, lumbar in 8.3% and sacral segments in 3.5%. 63% of cases had zoster associated pain. One case had motor involvement.3.57% of the patients were HIV positive. This study shows a lower age incidence of herpes zoster HIV positivity and zoster associated pain as compared to other studies. The pattern of segmental involvement in herpes zoster seen in this study was similar to other studies.

    The environment of space results in a multitude of challenges to the human physiology that present barriers to extended habitation and exploration. Over 40 years of investigation to define countermeasures to address space flight adaptation has left gaps in our knowledge regarding mitigation strategies partly due to the lack of investigative tools, monitoring strategies, and real time diagnostics to understand the central causative agent(s) responsible for physiologic adaptation and maintaining homeostasis. Spaceflight-adaptation syndrome is the combination of space environmental conditions and the synergistic reaction of the human physiology. Our work addresses the role of oxidative stress and damage (OSaD) as a negative and contributing Risk Factor (RF) in the following areas of combined spaceflight related dysregulation: i) radiation induced cellular damage [1], [2] ii) immune impacts and the inflammatory response [3], [4] and iii) varicella zoster virus (VZV) reactivation [5]. Varicella-zoster (VZV)/Chicken Pox virus is a neurotropic human alphaherpes virus resulting in varicella upon primary infection, suppressed by the immune system becomes latent in ganglionic neurons, and reactivates under stress events to re-express in zoster and possibly shingles. Our laboratory has developed a complex three-dimensional (3D) normal human neural tissue model that emulates several characteristics of the human trigeminal ganglia (TG) and allows the study of combinatorial experimentation which addresses, simultaneously, OSaD associated with Spaceflight adaptation and habitation [6]. By combining the RFs of microgravity, radiation, and viral infection we will demonstrate that living in the space environment leads to significant physiological consequences for the peripheral and subsequently the central nervous system (PNS, CNS) associated with OSaD generation and consequentially endangers long-duration and exploration-class missions.

    Herpes zoster is a common dermatological condition which affects up to 20% of the population, most frequently involving the thoracic and facial dermatomes with sacral lesions occurring rarely and only a few reported cases of penile shingles. We report two cases of unusual penile clinical presentations of varicella zoster virus infection in immunocompetent men. The patients presented with grouped clusters of vesicles and erythema on the left side of penile shaft and posterior aspect of the left thigh and buttock, involving s2-s4 dermatomes. The lesions resolved quickly upon administration of oral antiviral therapy. Penile herpes zoster should not be overlooked in patients with unilateral vesicular rash.

    Full Text Available Abstract Background Primary maternal infection with cytomegalovirus (CMV, parvovirus B19 (B19V, and varicella-zoster virus (VZV may result in adverse pregnancy outcomes like congenital infection or foetal loss. Women working in child day care have an increased exposure to CMV, B19V, and VZV. By comparing the seroprevalence of IgG-class antibodies against CMV, VZV and B19V in female day care workers (DCW with the seroprevalence in women not working in day care this study aimed to assess the association between occupation and infection. Methods A cross-sectional design was used. Out of a random sample of 266 day care centres, demographic data, data on work history, and blood samples were collected from 285 women from 38 centres. In addition, blood samples and basic demographics from women who participated in a cross-sectional survey of the Amsterdam population (2004 were used. All blood samples were tested for IgG-class antibodies against CMV, B19V, and VZV. Results Twenty-seven percent of the DCW were still susceptible to B19V or CMV. Working in day care was independently associated with B19V infection in all DCW (prevalence ratio [PR] 1.2; 95 % CI 1.1–1.3, and with CMV infection in DCW of European origin only (PR 1.7; 95 % CI 1.3–2.3. Almost all women born outside Europe tested seropositive for CMV (96 %. All DCW tested seropositive for VZV, compared to only 94 % of the women not working in day care. Conclusion This study confirms the clear association between employment in child day care centres and infection with CMV and B19V. Intervention policies, like screening of new employees and awareness campaigns emphasizing hygienic measures among DCW, should be implemented urgently to improve the maternal health of these women and the health of their offspring.

  5. The Varicella-Zoster Virus Immediate-Early 63 protein affects chromatin controlled gene transcription in a cell-type dependent manner

    2007-10-01

    Full Text Available Abstract Background Varicella Zoster Virus Immediate Early 63 protein (IE63 has been shown to be essential for VZV replication, and critical for latency establishment. The activity of the protein as a transcriptional regulator is not fully clear yet. Using transient transfection assays, IE63 has been shown to repress viral and cellular promoters containing typical TATA boxes by interacting with general transcription factors. Results In this paper, IE63 regulation properties on endogenous gene expression were evaluated using an oligonucleotide-based micro-array approach. We found that IE63 modulates the transcription of only a few genes in HeLa cells including genes implicated in transcription or immunity. Furthermore, we showed that this effect is mediated by a modification of RNA POL II binding on the promoters tested and that IE63 phosphorylation was essential for these effects. In MeWo cells, the number of genes whose transcription was modified by IE63 was somewhat higher, including genes implicated in signal transduction, transcription, immunity, and heat-shock signalling. While IE63 did not modify the basal expression of several NF-κB dependent genes such as IL-8, ICAM-1, and IκBα, it modulates transcription of these genes upon TNFα induction. This effect was obviously correlated with the amount of p65 binding to the promoter of these genes and with histone H3 acetylation and HDAC-3 removal. Conclusion While IE63 only affected transcription of a small number of cellular genes, it interfered with the TNF-inducibility of several NF-κB dependent genes by the accelerated resynthesis of the inhibitor IκBα.

    To investigate whether there is a possible viral transmission using mesenchymal stem cells (MSCs) in autologous or allogeneic transplantation in the context of osteoarthritis (OA) patients. The presence of parvovirus B19 (B19), varicella zoster virus (VZV), and human herpesvirus-6 (HHV-6) was studied in MSCs from bone marrow of patients with OA and healthy controls. MSCs were prepared from bone marrow aspirates obtained from 18 patients undergoing joint replacement as a result of OA and from 10 healthy controls. DNA was extracted from primary MSCs' culture established from these cells and quantitative real-time polymerase chain reaction was performed to analyse the prevalence and viral load of B19, VZV and HHV-6. The prevalence of total viral DNA among patients with OA was 16.7% (3/18), with a mean viral load of 29.7 copies/microg of DNA. One out of 18 was positive for B19 (viral load, 61.2 copies/microg of DNA), two for VZV (mean viral load, 14.4 copies/microg of DNA), and none for HHV-6. The prevalence of total viral DNA in the control group was 20% (2/10), with a mean viral load of 13.4 copies/microg of DNA. Both positive results were of B19 parvoviruses. There were no statistically significant differences among patients and controls. This first approach to the viral prevalence in MSCs of bone marrow in OA patients and healthy controls seems to show a very low risk of viral transmission or reactivation in a possible MSCs' transplantation.

    The pathogenesis of herpes zoster is closely linked to reduced varicella-zoster virus-specific cell-mediated immunity. However, little is known about the interplay between natural killer cells and psychological stress in the pathogenesis of herpes zoster. This study aimed to investigate possible associations among natural killer cells, T cells and psychological stress in herpes zoster. Interferon-gamma secretion from natural killer cell, psychological stress events, stress cognition scale scores and cytomegalovirus-specific cell-mediated immunity were compared between 44 patients with herpes zoster and 44 age- and gender-matched control subjects. A significantly lower median level of interferon-gamma secreted by natural killer cells was observed in patients with a recent diagnosis of herpes zoster than in control subjects (582.7 pg/ml vs. 1783 pg/ml; P = 0.004), whereas cytomegalovirus-specific cell-mediated immunity was not associated with herpes zoster. Psychological stress events and high stress cognition scale scores were significantly associated in patients with herpes zoster (Pherpes zoster display reduced interferon-gamma secretion from natural killer cells and frequent previous psychological stress events compared with controls. However, reduced natural killer cell activity is not an immunological mediator between psychological stress and herpes zoster.

    VZV IE62 is an essential, immediate-early, tegument protein and consists of five domains. We generated recombinant viruses carrying mutations in the first three IE62 domains and tested their influence on VZV replication kinetics. The mutations in domain I did not affect replication kinetics while domain II mutations, disrupting the DNA binding and dimerization domain (DBD), were lethal for VZV replication. Mutations in domain III of the nuclear localization signal (NLS) and the two phosphorylation sites S686A/S722A resulted in slower growth in early and late infection respectively and were associated with IE62 accumulation in the cytoplasm and nucleus respectively. This study mapped the functional domains of IE62 in context of viral infection, indicating that DNA binding and dimerization domain is essential for VZV replication. In addition, the correct localization of IE62, whether nuclear or cytoplasmic, at different points in the viral life cycle, is important for normal progression of VZV replication. - Highlights: • Mutation of IE62 domain I did not affect VZV replication in melanoma cells. • IE62 domain II and III are important for VZV replication in melanoma cells. • Mutations of IE62 domain II (DBD) were lethal for virus replication. • Mutations of IE62 NLS and phosphorylation sites inhibited VZV replication. • NLS and S686A/S722A mutations altered localization of IE62 during early and late infection.

    2010-01-01

    Full Text Available Herpes zoster oticus also known as Ramsay Hunt syndrome is a rare complication of herpes zoster in which reactivation of latent varicella zoster virus infection in the geniculate ganglion causes otalgia, auricular vesicles, and peripheral facial paralysis. Ramsay Hunt syndrome is rare in children and affects both sexes equally. Incidence and clinical severity increases when host immunity is compromised. Because these symptoms do not always present at the onset, this syndrome can be misdiagnosed. Although secondary to Bell′s palsy in terms of the cause of acute atraumatic peripheral facial paralysis, Ramsay Hunt syndrome, with incidence ranged from 0.3 to 18%, has a worse prognosis. Herpes zoster oticus accounts for about 12% cases of facial palsy, which is usually unilateral and complete and full recovery occurs in only about 20% of untreated patients. The most advisable method to treat Ramsay Hunt syndrome is the combination therapy with acyclovir and prednisone but still not promising, and several prerequisites are required for better results. We present a case of 32-year-old man suffering from Ramsay Hunt syndrome with grade V facial palsy treated effectively with rehabilitation program, after the termination of the combination therapy of acyclovir and prednisone.

    Shingles is a painful rash that results from reactivation of latent varicella-zoster virus in the dorsal root ganglia or cranial nerves. In this article an update is presented on the prevention and pharmacological treatment of the secondary pain from the virus infection. The most effective way to prevent post-herpetic neuralgia and its consequences is the prevention of herpes itself. A live attenuated vaccine (the Oka strain varicella zoster virus) has been available for several years, and is approved in adults aged 50 years old. Although this vaccine has shown to be effective against herpes zoster and post-herpetic neuralgia, its effectiveness decreases with age and is contraindicated in patients with some form of immunosuppression. Today the recombinant vaccines provide an alternative, and may be administered to immunocompromised persons. Copyright © 2016 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

    When a patient presents with acute voiding dysfunction without a typical skin rash, it may be difficult to make a diagnosis of herpes zoster. Here, we present a case of scrub typhus in a 25-year-old man with the complication of urinary dysfunction. The patient complained of loss of urinary voiding sensation and constipation. After eight days, he had typical herpes zoster eruptions on the sacral dermatomes and hypalgesia of the S1-S5 dermatomes. No cases of dual infection with varicella zoster virus and Orientia tsutsugamushi were found in the literature. In the described case, scrub typhus probably induced sufficient stress to reactivate the varicella zoster virus. Early recognition of this problem is imperative for prompt and appropriate management, as misdiagnosis can lead to long-term urinary dysfunction. It is important that a diagnosis of herpes zoster be considered, especially in patients with sudden onset urinary retention.

    Full Text Available Varicella zoster virus infection, which causes chickenpox and herpes zoster (HZ, is not uncommon in the general population. Varicella zoster virus can be latent in cranial nerve or dorsal root ganglia, and reactivate several decades later to produce vesicles with post-herpetic neuralgia. HZ myelitis usually occurs in elderly or immunocompromised patients. We report here a case of HZ myelitis of the cervical spinal cord in a 35-year-old woman who was immunocompetent. Cervical myelitis developed 1 month after the eruption of vesicles. Pure sensation loss was limited initially from the C2 to T1 dermatomes, but later progressed to lower limb sensory loss and sphincter function impairment. The patient's motor function was also mildly affected. Despite the initial rapid neurological deterioration, the symptoms dramatically improved after 5 days of parenteral acyclovir and steroid administration with rehabilitation. We therefore propose that early medical intervention is necessary for better and earlier recovery.

    Herpes zoster optic neuropathy (HZON) is a rare manifestation of herpes zoster ophthalmicus (HZO). The aim of our study was to better characterize the clinical features, therapeutic choices, and visual outcomes in HZON. A retrospective chart review was performed at multiple academic eye centers with the inclusion criteria of all eyes presenting with optic neuropathy within 1 month of cutaneous zoster of the ipsilateral trigeminal dermatome. Data were collected regarding presenting features, treatment regimen, and visual acuity outcomes. Six patients meeting the HZON inclusion criteria were identified. Mean follow-up was 2.75 months (range 0.5-4 months). Herpes zoster optic neuropathy developed at a mean of 14.1 days after initial rash (range 6-30 days). Optic neuropathy was anterior in 2 eyes and retrobulbar in 4 eyes. Other manifestations of HZO included keratoconjunctivitis (3 eyes) and iritis (4 eyes). All patients were treated with systemic antiviral therapy in addition to topical and/or systemic corticosteroids. At the last follow-up, visual acuity in 3 eyes had improved relative to presentation, 2 eyes had worsened, and 1 eye remained the same. The 2 eyes that did not receive systemic corticosteroids had the best observed final visual acuity. Herpes zoster optic neuropathy is an unusual but distinctive complication of HZO. Visual recovery after HZON is variable. Identification of an optimal treatment regiment for HZON could not be identified from our patient cohort. Systemic antiviral agents are a component of HZON treatment regimens. Efficacy of systemic corticosteroids for HZON remains unclear and should be considered on a case-by-case basis.

    2017-12-01

    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. We consider the complex backdrop of VZV virology, pathogenesis and immune responses in the absence of suitable animal models and examine the changing epidemiology of VZV disease. We review the vaccines' efficacy, safety, effectiveness and coverage using evidence from trials, observational studies from large routine health datasets and clinical post-marketing surveillance studies and outline newer developments in subunit and inactivated vaccines. Expert commentary: Safe and effective, varicella and zoster vaccines have already made major inroads into reducing the burden of VZV disease globally. As these live vaccines have the potential to reactivate and cause clinical disease, developing alternatives that do not establish latency is an attractive prospect but will require better understanding of latency mechanisms.

    The objective of this review was to collect reports of keratitis in association with herpes zoster virus (HZV) or varicella zoster virus (VZV) vaccines. HZV vaccination is intended for at-risk adult populations and VZV vaccination is intended for all pediatric patients. We reviewed the literature and reports of keratitis in association with herpes zoster or varicella vaccine from the National Registry of Drug-Induced Ocular Side Effects and the World Health Organization. Twenty-four cases of unilateral keratitis in association with VZV vaccines were collected from the adverse reaction databases and literature. In most cases, the onset of keratitis occurred within days of vaccination and resolved with topical steroid eye drops and oral acyclovir. Data suggest that keratitis in association with herpes zoster or varicella vaccine is rare, is usually self-limited or resolves with treatment. The mechanism may be the persistence of viral antigens in the cornea after VZV vaccination or herpes zoster ophthalmicus. This reaction is probable, given the plausible biological mechanism, the temporal relationship between vaccination and keratitis, and overall patterns of presentation after vaccination.

    Science.gov (United States)

    2013-01-01

    Background The herpes zoster burden of disease in Sweden is not well investigated. There is no Swedish immunization program to prevent varicella zoster virus infections. A vaccine against herpes zoster and its complications is now available. The aim of this study was to estimate the herpes zoster burden of disease and to establish a pre-vaccination baseline of the minimum incidence of herpes zoster. Methods Data were collected from the Swedish National Health Data Registers including the Patient Register, the Pharmacy Register, and the Cause of Death Register. The herpes zoster burden of disease in Sweden was estimated by analyzing the overall, and age and gender differences in the antiviral prescriptions, hospitalizations and complications during 2006-2010 and mortality during 2006-2009. Results Annually, 270 per 100,000 persons received antiviral treatment for herpes zoster, and the prescription rate increased with age. It was approximately 50% higher in females than in males in the age 50+ population (rate ratio 1.39; 95% CI, 1.22 to 1.58). The overall hospitalization rate for herpes zoster was 6.9/100,000 with an approximately three-fold increase for patients over 80 years of age compared to the age 70-79 group. A gender difference in hospitalization rates was observed: 8.1/100,000 in females and 5.6/100,000 in males. Herpes zoster, with a registered complication, was found in about one third of the hospitalized patients and the most common complications involved the peripheral and central nervous systems. Death due to herpes zoster was a rare event. Conclusions The results of this study demonstrate the significant burden of herpes zoster disease in the pre-zoster vaccination era. A strong correlation with age in the herpes zoster- related incidence, hospitalization, complications, and mortality rates was found. In addition, the study provides further evidence of the female predominance in herpes zoster disease. PMID:24330510

    The aim of the article is to highlight the distinguishing features of secondary varicella gingival infection in an older women. Herpes zoster is an acute sporadic, painful viral infection in older people caused by the reactivation of the latent varicella zoster virus. Herpes zoster affecting the gingiva without any dermal lesions is a rare pathological condition that mimics many intraoral vesiculobullous lesions. The ambiguous nature of this condition creates a diagnostic dilemma. A 58-year-old woman presented with an acute, unilateral and persistent burning sensation and pain in the gingiva with desqaumating vesicullobulous lesion. The women was diagnosed with secondary varicella zoster infection. Herpes zoster of the gingiva could manifest as painful desquamative vesicular lesions, pulpal or other painful neuralgic condition in older individuals which need careful diagnosis before formulating appropiate treatment plan. © 2016 John Wiley & Sons A/S and The Gerodontology Association.

    SUMMARY Impairment of varicella zoster virus (VZV)-specific cell-mediated immunity, including impairment due to immunosenescence, is associated with an increased risk of developing herpes zoster (HZ), whereas levels of anti-VZV antibodies do not correlate with HZ risk. This crucial role of VZV-specific cell-mediated immunity suggests that boosting these responses by vaccination will be an effective strategy for reducing the burden of HZ. Other strategies focus on preventing the major complication of HZ – post-herpetic neuralgia. These strategies include pre-emptive treatment with drugs such as tricyclic antidepressants, anticonvulsants and analgesics. PMID:20510262

    Herpes zoster is an infectious vesicular skin rash in a dermatomal distribution caused by Varicella zoster virus. It occurs very uncommonly in sacral dermatomes. We describe a case with rash on penis and scrotum due to involvement of S2 dermatome in a young male. The disease followed an uneventful course and the patient recovered completely without any sequelae or complications. This case is being presented to highlight its unusual location and to discuss differentiation from another viral infection commonly seen at this site. (author)

    Acute urinary retention in women is rare. The varicella-zoster virus causes inflammatory lesions of the sensory-root ganglions, meninges and, less frequently, spinal cord. Herpes zoster has been reported to affect, although rarely, lower urinary tract innervations, and acute urinary retention can be thought to occur in the presence of sacral dermatome involvement. Usually it is located in S2-4 dermatome and the prognosis for acute urinary retention is benign resolving in about 20 days. We present a case in which the S1 dermatome was involved and acute urinary retention developed. After 10 days of specific therapy and self-catheterization the problem resolved.

    Most people are initially infected with varicella zoster virus (VZV) at a young age and this infection results in chickenpox. VZV then becomes latent and reactivates later in life resulting in herpes zoster (HZ) or "shingles". Often VZV infects neurons of the trigeminal ganglia to cause ocular problems, orofacial disease and occasionally a chronic pain condition termed post-herpetic neuralgia (PHN). To date, no model has been developed to study orofacial pain related to varicella zoster. Importantly, the incidence of zoster associated pain and PHN is known to be higher in women, although reasons for this sex difference remain unclear. Prior to this work, no animal model was available to study these sex-differences. Our goal was to develop an orofacial animal model for zoster associated pain which could be utilized to study the mechanisms contributing to this sex difference. To develop this model VZV was injected into the whisker pad of rats resulting in IE62 protein expression in the trigeminal ganglia; IE62 is an immediate early gene in the VZV replication program. Similar to PHN patients, rats showed retraction of neurites after VZV infection. Treatment of rats with gabapentin, an agent often used to combat PHN, ameliorated the pain response after whisker pad injection. Aversive behavior was significantly greater for up to 7 weeks in VZV injected rats over control inoculated rats. Sex differences were also seen such that ovariectomized and intact female rats given the lower dose of VZV showed a longer affective response than male rats. The phase of the estrous cycle also affected the aversive response suggesting a role for sex steroids in modulating VZV pain. These results suggest that this rat model can be utilized to study the mechanisms of 1) orofacial zoster associated pain and 2) the sex differences underlying zoster associated pain.

    There are many causes of acute urinary retention. Reported here is a case of one of the more rare causes: herpes zoster. Fewer than 70 cases have been reported in the literature since 1890. In the present clinical environment where many patients are immunocompromised, reports of herpes zoster and its sequelae are no longer thought of as anecdotal. The virus may interrupt the detrusor reflex due to involvement of the sacral dorsal root ganglia. Urinary retention with sensory loss of both bladder and rectum as well as flaccid paralysis of the detrusor can develop in patients with herpes zoster. Fortunately, the outcome of this process is benign and full recovery of the detrusor is likely.

    Full Text Available Herpes zoster is a common dermatological condition which affects up to 20% of the population, most frequently involving the thoracic and facial dermatomes with sacral lesions occurring rarely and only a few reported cases of penile shingles. Case report: We report two cases of unusual penile clinical presentations of varicella zoster virus infection in immunocompetent men. The patients presented with grouped clusters of vesicles and erythema on the left side of penile shaft and posterior aspect of the left thigh and buttock, involving s2-s4 dermatomes. The lesions resolved quickly upon administration of oral antiviral therapy. Conclusion: Penile herpes zoster should not be overlooked in patients with unilateral vesicular rash.

    Herpes zoster (HZ), a common vesiculo-erythematous skin disease associated with reactivation of varicella zoster virus in the cranial nerve, dorsal root, and autonomic ganglia, is accompanied by several related symptoms represented by postherpetic neuralgia. Among them, involvement of vesicorectal dysfunction is relatively rare. The vesicorectal symptom can usually be recovered in transient course, but is quite important in terms of impaired quality of life. Male individuals affected with HZ and skin lesions on sacral dermatome have been reported as independent risk factors of zoster-related voiding dysfunction. In this study, urinary symptoms were focused upon and six patients with zoster-related voiding dysfunction at a single faculty of dermatology in Japan from 2009 to 2014 were retrospectively analyzed. All patients showed HZ lesions on the sacral area and the urinary symptom recovered in approximately 2 months (14 days to 7 months). The term of treatment for zoster-associated urinary dysfunction was positively correlated with that for zoster-related pain without significance (r = 0.661, P = 0.153). Average treatment term for pain relief of sacral HZ accompanied by voiding dysfunction (91.3 ± 76.44 days) was significantly longer than that of sacral HZ without urinary symptom (18.9 ± 20.42 days) (P = 0.032). These results suggested that zoster-related voiding dysfunction would mainly be involved in sacral HZ and closely associated with severity of zoster-related pain. Dermatologists should be aware that severe zoster-related pain accompanied by sacral HZ, which is related to prolonged treatment of pain relief, can be a predictive factor of voiding dysfunction. © 2015 Japanese Dermatological Association.

Our patient was initially admitted to a neighborhood hospital because of nausea and loss of appetite of 10 days' duration. The day after hospitalization, she developed skin vesicles along the first division of the trigeminal nerve, with severe lid swelling and conjunctival injection. On suspicion of meningoencephalitis caused by varicella zoster virus, antiviral therapy with vidarabine and betamethasone was started. Seventeen days later, complete ptosis and ophthalmoplegia developed in the right eye. The light reflex in the right eye was absent and anisocoria was present, with the right pupil larger than the left. Fat-suppressed enhanced T1-weighted magnetic resonance images showed high intensity areas in the muscle cone, cavernous sinus, and orbital optic nerve sheath. Our patient was diagnosed with orbital apex syndrome, and because of skin vesicles in the first division of the trigeminal nerve, the orbital apex syndrome was considered to be caused by herpes zoster ophthalmicus. After the patient was transferred to our hospital, prednisolone 60 mg and vidarabine antiviral therapy was started, and fever and headaches disappeared five days later. The ophthalmoplegia and optic neuritis, but not the anisocoria, gradually resolved during tapering of oral therapy. From the clinical findings and course, the cause of the orbital apex syndrome was most likely invasion of the orbital apex and cavernous sinus by the herpes virus through the trigeminal nerve ganglia.Keywords: varicella zoster virus, orbital apex syndrome, herpes zoster ophthalmicus, complete ophthalmoplegia

    Background The incidence and risk factors for herpes zoster have been studied in cross-sectional and cohort studies, although most such studies have been conducted in Western countries. Evidence from Asian populations is limited, and no cohort study has been conducted in Asia. We are conducting a 3-year prospective cohort study in Shozu County in Kagawa Prefecture, Japan to determine the incidence and predictive and immunologic factors for herpes zoster among Japanese. Methods The participants are followed for 3 years, and a telephone survey is conducted every 4 weeks. The participants were assigned to 1 of 3 studies. Participants in study A gave information on past history of herpes zoster and completed health questionnaires. Study B participants additionally underwent varicella-zoster virus (VZV) skin testing, and study C participants additionally underwent blood testing. If the participants develop herpes zoster, we evaluate clinical symptoms, measure cell-mediated immunity and humoral immunity using venous blood sampling, photograph skin areas with rash, conduct virus identification testing by polymerase chain reaction (PCR) and virus isolation from crust sampling, and evaluate postherpetic pain. Results We recruited 12 522 participants aged 50 years or older in Shozu County from December 2009 through November 2010. The participation rate was 65.7% of the target population. Conclusions The present study is likely to provide valuable data on the incidence and predictive and immunologic factors for herpes zoster in a defined community-based population of Japanese.

    Full Text Available Several prokaryotic and eukaryotic expression systems have been used for in vitro production of viruses’ proteins. However eukaryotic expression system was always the first choice for production of proteins that undergo post-translational modification such as glycosylation. Recombinant baculoviruses have been widely used as safe vectors to express heterologous genes in the culture of insect cells, but the manipulation involved in creating, titrating, and amplifying viral stocks make it time consuming and laborious. Therefore, to facilitate rapid expression in insect cell, a plasmid based expression system was used to express herpes simplex type 1 glycoprotein D (HSV-1 gD and varicella zoster glycoprotein E (VZV gE. Recombinant plasmids were generated, transfected into insect cells (SF9, and both glycoproteins were expressed 48 h post-infection. A protein with approximately molecular weight of 64-kDa and 98-kDa for HSV-1 gD and VZV gE respectively was expressed and confirmed by SDS. Proteins were detected in insect cells cytoplasm and outer membrane by immunofluorescence. The antigenicity and immunoreactivity of each protein were confirmed by immunoblot and ELISA. Results suggest that this system can be an alternative to the traditional baculovirus expression for small scale expression system in insect cells.

    Herpes zoster (shingles) is caused when the varicella zoster virus that has remained latent since an earlier varicella infection (chicken-pox) is reactivated. Herpes Zoster is a less common and endemic disease than varicella: factors causing reactivation are still not well known, but it occurs in older and/or immunocompromised individuals. Following reactivation, centrifugal migration of herpes zoster virus (HZV) occurs along sensory nerves to produce a characteristic painful cutaneous or mucocutaneous vesicular eruption that is generally limited to the single affected dermatome. Herpes zoster may affect any sensory ganglia and its cutaneous nerve: the most common sites affected are thoracic dermatomes (56%), followed by cranial nerves (13%) and lumbar (13%), cervical (11%) and sacral nerves (4%). Among cranial nerves, the trigeminal and facial nerves are the most affected due to reactivation of HZV latent in gasserian and geniculated ganglia. The 1st division of the trigeminal nerve is commonly affected, whereas the 2nd and the 3rd are rarely involved. During the prodromal stage, the only presenting symptom may be odontalgia, which may prove to be a diagnostic challenge for the dentist, since many diseases can cause orofacial pain, and the diagnosis must be established before final treatment. A literature review of herpes zoster of the trigeminal nerve is presented and the clinical presentation, differential diagnosis and treatment modalities are underlined. A case report is presented.

    Herpes zoster ophthalmicus (HZO) is a clinical manifestation of the reactivation of latent varicella zoster virus (VZV) infection and is more common in people with diminished cell-mediated immunity. Lesions and pain correspond to the affected dermatomes, mostly in first or second trigeminal branch and progress from maculae, papules to vesicles and form pustules, and crusts. Complications are cutaneous, visceral, neurological, ocular, but the most debilitating is post-herpetic neuralgia. Herpes zoster ophthalmicus may affect all the ophthalmic structures, but most severe eye-threatening complications are panuveitis, acute retinal necrosis (ARN) and progressive outer retinal necrosis (PORN) as well. Antiviral medications remain the primary therapy, mainly useful in preventing ocular involvement when begun within 72 hours after the onset of the rash. Timely diagnosis and management of HZO are critical in limiting visual morbidity. Vaccine in adults over 60 was found to be highly effective to boost waning immunity what reduces both the burden of herpes zoster (HZ) disease and the incidence of post-herpetic neuralgia (PHN).

    Full Text Available Herpes zoster (HZ occurs in older ages with activation of varicella-zoster virus (VZV which persists in a dormant phase within the dorsal root ganglia. The incidence of HZ in immunosuppressed patients is 20-100 times higher and the clinical progress is more severe than in immunocompetent individuals. A 48-year-old man who had been diagnosed with acute myelocytic leukemia type M3 and had been treated with immunosuppressive agents was admitted to our clinic. The patient was clinically diagnosed as having HZ. He was treated with acyclovir 800 mg five times daily for 7 days. In the consecutive three months, he attended our clinic again with similar complaints. The left cervical (C5, C6 dermatomes were involved at the fourth attack of HZ. Multinucleated giant cells were determined on the Tzanck smear. VZV DNA was detected by polymerase chain reaction (PCR. Treatment with valacyclovir 1 g three times daily for 14 days was prescribed and then, prophylactic treatment with valacyclovir 500 mg two times a day was administered. Although immunosuppressive treatment was continued, no new attacks of herpes zoster occurred. We think that prophylactic antiviral therapy should be initiated in immunosuppressive individuals who have recurrent herpes zoster attacks.

    Varicella is a self-limiting and relatively mild disease of childhood, although it is frequently more severe and complicated among the immunocompromised rheumatology patients on immunomodulator therapies. In addition, future reactivation of the dormant virus in dorsal root ganglia may cause herpes zoster infection, which can be very debilitating. In this manuscript, we discuss the nature of this infection along with its potential vaccine especially among rheumatology patients.

    Antarctica is a useful analog for spaceflight, as both environments are remote, isolated, and with limited resources. While previous studies have demonstrated increased asymptomatic viral shedding in both the Antarctic and spaceflight environments, clinical manifestations of reactivated viral disease have been less frequently identified. We sought to identify the incidence of clinical herpes zoster from viral reactivation in the Antarctic winter-over population. Medical records from the 2014 winter season were reviewed for the incidence of zoster in U.S. Antarctic personnel and then compared to the age-matched U.S. Five cases of clinical herpes zoster occurred in the Antarctic Station population of 204 persons, for an incidence of 33.3 per 1000 person-years vs. 3.2 per 1000 person-years in the general population. Four cases were in persons under age 40, yielding an incidence of 106.7 per 1000 person-years in persons ages 30-39 compared to an incidence of 2.0 per 1000 person-years in the same U.S. age group. Immune suppression due to the stressful Antarctic environment may have contributed to the increased incidence of herpes zoster in U.S. Antarctic personnel during the winter of 2014. Working and living in isolated, confined, and extreme environments can cause immune suppression, reactivating latent viruses and increasing viral shedding and symptomatic disease. Such changes have been observed in other austere environments, including spaceflight, suggesting that clinical manifestations of viral reactivation may be seen in future spaceflight.Reyes DP, Brinley AA, Blue RS, Gruschkus SK, Allen AT, Parazynski SE.

    We present the case of a 40-year-old female patient suffering from recurrent herpes zoster and postherpetic neuralgia. Herpes zoster has recurred several times per year for more than 15 years. At admission, rash localised on the right sacral region and accompanied by neuralgia had lasted for 3 months. Standard out-patient treatment remained unsuccessful. A multimodal integrative therapy regimen including fasting, hydrotherapy, leech application and treatment with autologous blood led to rapid healing of herpetic lesions and persistent pain relief. The case is discussed.

    The consequences of the epidemiology of varicella for zoster epidemiology are still debated. We therefore compared the frequency of herpes zoster in an adult population with virtually no varicella zoster virus (VZV) exposure with that in the general population (GP). We performed a national, multicenter, observational, exposed versus nonexposed, comparative study. The nonexposed population consisted of members of contemplative monastic orders (CMO) of the Roman Catholic Church living in 40 isolated monasteries in France. The exposed population consisted of a sample of the GP representative of the French population in terms of age group, sex, socio-occupational categories, and regions. The primary analysis population comprised 920 members of CMO (41.5% nuns; mean age, 64.2 years) and 1533 members of the GP (51.9% women; mean age, 64.6 years). The reported frequency of zoster was 16.2% among CMO and 15.1% in the GP (P = .27, adjusted for sex and age). The reported mean age of onset of zoster was 54.8 and 48.6 years, respectively (P = .06). This study failed to demonstrate an increased risk or earlier onset of zoster in members of CMO not exposed to VZV, compared with that in the GP. Although adults highly exposed to VZV could have a reduced risk of zoster, compared with the GP, our results suggest that the opposite is not true: adults not exposed to VZV are not at increased risk of zoster when compared with the GP, challenging the relevance of the assumptions and forecasts of current epidemiological models.

    Full Text Available Introduction: Herpes Zoster (HZ is rare in infancy and results from reactivation of varicella-zoster virus, latent in the dorsal root ganglia of sensory or cranial nerves after primary infection (chickenpox. Case Report: We describe the case of an healthy infant, three months old, without previous clinical symptoms of chickenpox, in spite of having contacted with the disease at two weeks of life. She was hospitalized for vesicular-papular rash involving unilaterally dermatomes L4 and L5 and was treated with acyclovir with good clinical outcome. Conclusion: The immaturity of the immune system and the interference of maternal antibodies contribute to the manifestation of HZ in the first year of life. In a previously healthy child it is not recommended the exclusion of underlying immunodeficiency or malignant disease.

  12. Varicella-zoster virus (VZV) origin of DNA replication oriS influences origin-dependent DNA replication and flanking gene transcription.

    The VZV genome has two origins of DNA replication (oriS), each of which consists of an AT-rich sequence and three origin binding protein (OBP) sites called Box A, C and B. In these experiments, the mutation in the core sequence CGC of the Box A and C not only inhibited DNA replication but also inhibited both ORF62 and ORF63 expression in reporter gene assays. In contrast the Box B mutation did not influence DNA replication or flanking gene transcription. These results suggest that efficient DNA replication enhances ORF62 and ORF63 transcription. Recombinant viruses carrying these mutations in both sites and one with a deletion of the whole oriS were constructed. Surprisingly, the recombinant virus lacking both copies of oriS retained the capacity to replicate in melanoma and HELF cells suggesting that VZV has another origin of DNA replication.

    2013-01-01

    Live attenuated vaccines to prevent varicella and zoster have been available in the US for the past 17 years, with a resultant dramatic decrease in varicella incidence and a predicted future decrease in the incidence of zoster. The pathogenesis and immune responses to varicella zoster virus (VZV) as well as the safety and effectiveness of VZV vaccines are reviewed. The lack of sterilizing immunity provided by VZV vaccines has not prevented them from being safe and effective. Virological and pathological information concerning parallels and differences between VZV and herpes simplex virus (HSV) are highlighted. Although VZV and HSV are distinct pathogens, they appear to have similarities in target organs and immunity that provide an expectation of a high likelihood for the success of vaccination against HSV, and predicted to be similar to that of VZV.

    Herpes zoster (HZ) is caused by VZV reactivation that is facilitated by a declined immunity against varicella-zoster virus (VZV), but also occurs in immunocompetent individuals. Cytomegalovirus (CMV) infection is associated with immunosenescence meaning that VZV-specific T-cells could be less responsive. This study aimed to determine whether CMV infection could be a risk factor for the development of HZ. CMV IgG serostatus was determined in stored serum samples from previously prospectively recruited ambulatory adult HZ patients in the UK (N = 223) in order to compare the results with those from UK population samples (N = 1545) by means of a logistic regression (controlling for age and gender). Furthermore, we compared the UK population CMV seroprevalence with those from population samples from other countries (from Belgium (N1 = 1741, N2 = 576), USA (N = 5572) and Australia (N = 2080)). Furthermore, CMV IgG titers could be compared between UK HZ patients and Belgium N2 population samples because the same experimental set-up for analysis was used. We found UK ambulatory HZ patients to have a higher CMV seroprevalence than UK population samples (OR 1.56 [1.11 2.19]). CMV IgG seropositivity was a significant risk factor for HZ in the UK (OR 3.06 [1.32 7.04]. Furthermore, high CMV IgG titers (exceeding the upper threshold) were less abundant in CMV-seropositive Belgian N2 population samples than in CMV-seropositive UK HZ patients (OR 0.51 [0.31 0.82]. We found CMV-seroprevalence to increase faster with age in the UK than in other countries (P < 0.05). We conclude that CMV IgG seropositivity is associated with HZ. This finding could add to the growing list of risk factors for HZ. PMID:25905443

    The old adage we are our own worst enemies may perhaps be the most profound statement ever made when applied to man s desire for extraterrestrial exploration and habitation of Space. Consider the immune system protects the integrity of the entire human physiology and is comprised of two basic elements the adaptive or circulating and the innate immune system. Failure of the components of the adaptive system leads to venerability of the innate system from opportunistic microbes; viral, bacteria, and fungal, which surround us, are transported on our skin, and commonly inhabit the human physiology as normal and imunosuppressed parasites. The fine balance which is maintained for the preponderance of our normal lives, save immune disorders and disease, is deregulated in microgravity. Thus analogue systems to study these potential Risks are essential for our progress in conquering Space exploration and habitation. In this study we employed two known physiological target tissues in which the reactivation of hCMV and VZV occurs, human neural and lung systems created for the study and interaction of these herpes viruses independently and simultaneously on the innate immune system. Normal human neural and lung tissue analogues called tissue like assemblies (TLAs) were infected with low MOIs of approximately 2 x 10(exp -5) pfu hCMV or VZV and established active but prolonged low grade infections which spanned .7-1.5 months in length. These infections were characterized by the ability to continuously produce each of the viruses without expiration of the host cultures. Verification and quantification of viral replication was confirmed via RT_PCR, IHC, and confocal spectral analyses of the respective essential viral genomes. All host TLAs maintained the ability to actively proliferate throughout the entire duration of the experiments as is analogous to normal in vivo physiological conditions. These data represent a significant advance in the ability to study the triggering

    Simultaneous involvement of herpes zoster in multiple dermatomes is uncommon, and even more so in immunocompetent individuals. We report a case wherein a healthy adolescent boy presented with herpes zoster in two distinct dermatomes, raising concern for immunodeficiency, but he was found to be immunocompetent on further testing. A 14-year-old boy with no significant past medical history developed painless vesicular eruptions in two distinct distributions. Varicella zoster virus polymerase chain reaction was positive from unroofed vesicles in both regions. Initial laboratory studies disclosed abnormalities of unknown significance in natural killer (NK) cell percentage and function. The patient was treated with appropriate antiviral therapy. Repeat studies while healthy were not suggestive of an underlying NK cell defect. There are few case reports describing herpes zoster in two or more dermatomes in children. Previously described presentations most commonly occurred in the context of primary immunodeficiency, acquired immunodeficiency, or immunosuppressive medications. Because of the rarity of this presentation in immunocompetent patients, the authors recommend a thorough immune evaluation of all children presenting with isolated multidermatomal zoster. © 2014 Wiley Periodicals, Inc.

    Herpes zoster infection particularly involving the sacral dermatomes has been associated with bladder and bowel dysfunction, most commonly urinary retention. We report two patients who developed acute urinary retention, one of whom also had constipation, within days of herpes zoster skin lesions of the S2-S4 dermatomes. Herpes zoster is a reversible cause of neurogenic bladder and bowel dysfunction and should be considered in a patient that presents with acute urinary retention and/or constipation. Sensory abnormalities and flaccid detrusor paralysis are most likely involved in the pathogenesis.

    PURPOSE: To report a case of posterior ischemic optic neuropathy (PION following herpes zoster ophthalmicus (HZO. CASE REPORT: A 58-year-old woman with history of recent HZO in her right eye presented with acute painless loss of vision in the same eye to no light perception. Examination revealed a positive relative afferent pupillary defect and a normal appearing optic disc. Inflammatory and infiltrative lesions of the optic nerve were ruled out by laboratory and imaging studies. The patient received systemic acyclovir and prednisolone. Three months later, visual acuity improved to counting fingers, but the optic disc became pale and atrophic leading to a presumptive diagnosis of PION. Considering the positive PCR test for varicella zoster virus and the short time interval between the two presentations, HZO was considered as the most probable cause of the optic neuropathy. CONCLUSION: Herpes zoster ophthalmicus can be associated with PION.

    Herpes zoster (HZ) causes an often severe and painful rash in older people and may be complicated by prolonged pain (postherpetic neuralgia; PHN) and by dissemination in immune-compromised patients. HZ results from reactivation of latent varicella-zoster virus (VZV) infection, often associated with age-related or other causes of decreased T cell immunity. A live attenuated vaccine boosts this immunity and provides partial protection against HZ, but this decreases with age and declines over 8 years. Areas covered: A new HZ subunit (HZ/su) vaccine combines a key surface VZV glycoprotein (E) with a T cell-boosting adjuvant system (AS01 B ) and is administered by two intramuscular injections two months apart. Expert commentary: HZ/su showed excellent efficacy of ~90% in immunocompetent adults ≥50 and ≥70 years of age, respectively, in the ZOE-50 and ZOE-70 phase III controlled trials. Efficacy was unaffected by advancing age and persisted for >3 years. Approximately 9.5% of subjects had severe, but transient (1-2 days) injection site pain, swelling or redness. Compliance with both vaccine doses was high (95%). The vaccine will have a major impact on HZ management. Phase I-II trials showed safety and immunogenicity in severely immunocompromised patients. Phase III trial results are expected soon.

    Herpes zoster (HZ) duplex is a rare disease presentation. The mechanisms of varicella zoster virus (VZV) reactivation in multiple dermal regions are unknown. To present a HZ duplex case occurring in an immunocompetent woman and to analyze the possible underlying causes of HZ duplex. We present a HZ duplex case in an immunocompetent woman and analyzed the possible contributing factors in 36 HZ duplex cases. Continuously distributed variables were categorized by numbers and percentages. In our study, 24 cases (66.7%) were from Asia, 16 cases (44.4%) were in individuals ≥ 50 years of age, and 17 cases (47.2%) occurred in immunocompromised patients. Of the 36 cases, 23 involved women (63.9%) and 13 involved men. Eighteen patients suffering from HZ duplex, 13 of which were women (72.2%), did not suffer from any chronic systemic disease or have a long history of taking drugs. HZ duplex is a rare event that can occur in both immunocompetent and immunosuppressed individuals. HZ duplex might be associated with the Asia region, advanced age, immunosuppression, and being female.

If the patient has a severe, extended, or treatment-recalcitrant course of herpes zoster, this must be a red flag to search for underlying pathologies. Here, we report about a 64-year-old male patient with diabetes, who came to our emergency department because of general malaise, fever, chills, and a pronounced nuchal and facial swelling on the left side. Based on herpetiform-grouped vesicles and yellowish crusts, an impetiginized facial herpes zoster was diagnosed, and combined antiviral and antibiotic treatment was initiated. He was HIV negative. Despite intensified treatment, his situation worsened. We observed blasts in peripheral blood, but bone marrow biopsy was initially denied. Some days later after deterioration of his disease, he accepted further diagnostics. A myelodysplastic syndrome with blast excess (refractory anemia and blast excess II, RAEB II could be confirmed.

    Active infection with herpes zoster may cause acute urinary retention, especially when it involves sacral dermatomes. Although frank retention usually develops days to weeks after eruption of the typical rash, bladder incompetence infrequently develops first, raising concern over other, more ominous etiologies. In the case presented, rash appearance was delayed until six weeks after the initial onset of urinary retention, a much longer interval than previously reported. Occult herpes zoster infection should be considered in patients presenting with an acute neurogenic bladder of obscure cause.

    Valacyclovir and famciclovir enabled successful systemic therapy for treating herpes simplex virus (HSV) and varicella zoster virus (VZV) infection by their phosphorylation with viral thymidine kinase. Helicase-primase inhibitors (HPIs) inhibit the progression of the replication fork, an initial step in DNA synthesis to separate the double strand into two single strands. The HPIs amenamevir and pritelivir have a novel mechanism of action, once-daily administration with nonrenal excretory characteristics, and clinical efficacy for genital herpes. Amenamevir exhibits anti-VZV and anti-HSV activity while pritelivir only has anti-HSV activity. A clinical trial of amenamevir for herpes zoster has been completed, and amenamevir has been licensed and successfully used in 20,000 patients with herpes zoster so far in Japan. We have characterized the features of the antiviral action of amenamevir and, unlike acyclovir, the drug's antiviral activity is not influenced by the viral replication cycle. Amenamevir is opening a new era of antiherpes therapy. Copyright 2017 Clarivate Analytics.

    Erythema multiforme (EM) is an acute, self-limited, mucocutaneous disorder regarded as a hypersensitivity reaction which is triggered by various factors like infection, drugs, and food. Infectious agents are considered to be a major cause of EM other than idiopathic cause. A young girl presented with fluid-filled lesions all over the body of 3 days duration with history of similar lesions with fever in her sibling 2 weeks prior to admission. This was followed by large fluid-filled lesions with halo 3 days thereafter over the trunk, extremities suggesting target lesions of EM. The diagnosis was confirmed by cytology and positive serology. Varicella zoster virus (VZV) has rarely been reported as an etiological agent, despite its high incidence in childhood. VZV as an etiology of EM in a young girl has not been reported so far. This case was reported for its rare association of EM and varicella zoster and also for its rare presentation in a young girl.

    Herpes zoster is a common disorder characterized by a painful rash along a dermatome caused by reactivation of the varicella zoster virus (VZV). Muscle denervation injury from motor involvement is an uncommon phenomenon. Discordant distribution of the skin rash and motor nerve involvement, presenting as a skin rash in one body part and muscle weakness or pain from nerve involvement in another body part is an even more uncommonly reported finding. We present an unusual case of muscle denervation injury resulting from motor involvement of a peripheral nerve by VZV diagnosed by magnetic resonance imaging with cutaneous manifestations in a different dermatomal distribution. To the best of our knowledge, there has been no similar case reported in the English radiology literature. We suggest that whenever a radiologist notices MRI findings suggesting denervation injury and a cause not readily identified, VZV-related denervation injury should be included in the differential diagnosis, especially in an older immunocompromised patient.

    Herpes zoster (HZ) or "shingles" results from a reactivation of the varicella zoster virus (VZV) acquired during primary infection (chickenpox) and surviving in the dorsal root ganglia. In about 20% of cases, a complication occurs, known as post-herpetic neuralgia (PHN). A live attenuated vaccine against VZV is available for the prevention of HZ and subsequent PHN. The present study aims to update an earlier evaluation estimating the cost-effectiveness of the HZ vaccine from a Swiss third party payer perspective. It takes into account updated vaccine prices, a different age cohort, latest clinical data and burden of illness data. A Markov model was developed to simulate the lifetime consequences of vaccinating 15% of the Swiss population aged 65-79 y. Information from sentinel data, official statistics and published literature were used. Endpoints assessed were number of HZ and PHN cases, quality-adjusted life years (QALYs), costs of hospitalizations, consultations and prescriptions. Based on a vaccine price of CHF 162, the vaccination strategy accrued additional costs of CHF 17,720,087 and gained 594 QALYs. The incremental cost-effectiveness ratio (ICER) was CHF 29,814 per QALY gained. Sensitivity analyses showed that the results were most sensitive to epidemiological inputs, utility values, discount rates, duration of vaccine efficacy, and vaccine price. Probabilistic sensitivity analyses indicated a more than 99% chance that the ICER was below 40,000 CHF per QALY. Findings were in line with existing cost-effectiveness analyses of HZ vaccination. This updated study supports the value of an HZ vaccination strategy targeting the Swiss population aged 65-79 y.

    Full Text Available A 81-years-old caucasian man presented with acute burning pain in external auricular region and inside the auditory canal of right ear, associated with vesicular lesions on face, jugal and lingual mucosa. Physical examination revealed vesicular lesions in external auricular region and inside the auditory canal. Red blood cell count, leukocytes and platelets were normal. Presented HIV-1 and 2 both negative. Patient denied previous history of Diabetes and Hypertension. Treatment was initiated with Ceftriaxone 2g, Acyclovir 250mg, Prednisone 60mg and Bicarbonate Water for rinsing. After eight days of hospitalization, patient reported hearing loss in the right ear, chewing difficulty and mild pain in face. Auditory hearing loss and hypoacusis may suggest involvement of vestibulocochlear nerve. Figure 1 shows cicatricial crusted lesions following trigeminal nerve mandibular branch trajetory. Figure 2 reveals cicatricial crusted lesions following trigeminal nerve maxilar branch, trigeminal branch and erythematous scarring lesions in tongue, hypoglossal nerve region. Figure 3 reveals small crusted lesions following the trigeminal ophthalmic branch. Herpes zoster is caused by Varicella zoster virus (VZV reactivation in individuals who had Varicella in childhood or who were vaccinated. The presence of more than one dermatome affected is rare in immunocompetent individuals, being more prevalent in immunosuppressed individuals such as HIV positive and transplanted patients.1Disseminated herpes zoster can occur in any immunocompetent patient but predominates in elderly due to factors that compromise cellular immune response. 2,3

    Full Text Available Herpes zoster is a reactivation of the varicella zoster virus (VZV, which may remain dormant in the dorsal root ganglion of the trigeminal nerve for decades after the patient's initial exposure. The ophthalmic branch of the trigeminal nerve, i.e., the innervation to the ocular structures, is one of the most commonly involved dermatomes, giving rise to herpes zoster ophthalmicus (HZO. A 10-year-old indigenous Malaysian girl presented with a complaint of painful blurring of vision in the right eye for one week. It was followed a few days later by cutaneous vesicular eruptions over the right side of her face and nose and drooping of the right upper lid, associated with double vision. In children, the disease usually follows a mild course, resolving without residual damage. However, this child achieved a best corrected visual acuity of only 6/36 in the affected eye due to corneal scarring. The rashes healed by formation of disfiguring keloids over the right nasal area. This is another rarely reported complication of HZO in immunocompetent individuals.

    Zoster vaccine is a single dose live, attenuated vaccine (ZVL) indicated for individuals ≥50 years-old for the prevention of herpes zoster (HZ). Safety data from clinical trials and post-licensure studies provided reassurance that ZVL is generally safe and well tolerated. The objective of this review was to provide worldwide post-marketing safety information following 10 years of use and >34 million doses distributed. All post-marketing adverse experience (AE) reports received worldwide between 02-May-2006 and 01-May-2016 from healthcare professionals following vaccination with ZVL and submitted to the MSD AE global safety database, were analyzed. A total of 23,556 AE reports, 93% non-serious, were reported. Local injection site reactions (ISRs), with a median time-to-onset of 2 days, were the most frequently reported AEs followed by HZ. The majority of HZ reports were reported within 2 weeks of vaccination and considered, based on time-to-onset, pathogenesis of HZ, and data from clinical trials, to be caused by wild-type varicella-zoster virus (VZV). HZ confirmed by PCR analysis to be VZV Oka/Merck vaccine-strain was identified in an immunocompetent individual 8 months postvaccination and in 4 immunocompromised individuals. Disseminated HZ was reported very rarely (marketing use, was favorable and consistent with that observed in clinical trials and post-licensure studies. Copyright © 2017 Elsevier Ltd.

    Two hundred consecutive patients with herpes zoster attending the skin clinic at the Kilimanjaro Christian Medical Centre (KCMC) were examined and checked for HIV infection. They ranged in age from 10 months to 86 years with the majority in their 20s and 30s. The dermatomes involved were thoracic (97), trigeminal (50), cervical (37), lumbar (19) and sacral (3). Six (3%) had more than one dermatome involved and 2 (1%) had disseminated disease. Only 2 (1%) had severe ulceration of the skin and all healed in less than 4 weeks. In children under the age of 10 years and in adults between the ages of 20 and 49 years virtually 100% were HIV positive; even in the age group 50-59 more than three-quarters were HIV positive. We conclude that the presence of herpes zoster at any site is a good indication that the patient is HIV positive except in the teens and the very elderly.

    Herpes zoster is a common disease of adulthood. Its incidence is low in childhood and adolescence. Certain risk factors like hematological malignancies or immunosuppression due to any cause may lead to onset at an early age. There is a unilateral appearance of grouped vesicular eruption on an erythematous background which may involve contiguous dermatomes. Rarely the lesions may occur bilaterally in an otherwise healthy individual. We present a case of herpes zoster, with lesions having atypical distribution involving bilaterally symmetrical dermatomes over the lower chest.(author)

    2017-10-01

    Herpes zoster is characterized by unilateral grouped vesicles along the distribution of a dermatome. A global recurrence rate as low as 0.5%∼6.2% has been reported for herpes zoster. The recurrence of herpes zoster is higher in immunocompromised patients and older patients. The purpose of this study is to assess the frequency of herpes zoster recurrence and factors that can influence its recurrence. From January 2005 to December 2015, 14,343 patients with herpes zoster were enrolled in this study. The patients were diagnosed at Hallym University Medical Centers and Kangwon National University Hospital in Seoul, Gyeonggi, and Gangwon. Herpes zoster recurrence and patient characteristics were surveyed by medical record review and a telephonic survey. The overall frequency of herpes zoster recurrence was 1.18%. The frequency of recurrence was higher in women than in men. It was also higher in patients aged 50∼70 years than in patients who were younger or older than this. Additionally, we assessed that the frequency of recurrence was statistically higher in patients with a compromised immune system and in patients who experienced longer lasting pain during their first episode. The frequency of herpes zoster recurrence is more common in women, older age, patient with longer pain duration and immunocompromised patients.

    Full Text Available One hundred and seven cases (6 children and 101 adults of herpes zoster were recruited over a period of two years. The frequency of herpes zoster amongst skin OPD cases was found to be 0.34 per cent. The male to female ratio was 1.74:1. The most common prodromal symptom seen was paresthesia in 25 (23.36% cases followed by itching in 21 (19.62% cases.Most common presenting complaint was pain in 97 (90.65% cases. Ninety nine cases had classical herpes zoster followed by necrotic / ulcerated herpes zoster in 5 cases and hemorrhagic herpes zoster in 3 cases. Thoracic dermatome was the most common dermatome involved in 64 (59.8% cases followed by cervical in 17 (15.8% cases. Unidermatomal involvement was seen in 81 (75.7% cases, followed by multidermatomal in 18 (16.8% cases and disseminated in 8 (7.4% cases. Forty six cases were screened for HIV, out of them; six cases (4 males, 2 females were seropositive for HIV. Classical herpes zoster was a feature in four cases; however, one case each also had necrotic and hemorrhagic form of herpes zoster. To conclude, herpes zoster commonly occurs in young adults in India with presenting symptoms such as pain, itching and fever.

    In previous phase 1-2 clinical trials involving older adults, a subunit vaccine containing varicella-zoster virus glycoprotein E and the AS01B adjuvant system (called HZ/su) had a clinically acceptable safety profile and elicited a robust immune response. We conducted a randomized, placebo-controlled, phase 3 study in 18 countries to evaluate the efficacy and safety of HZ/su in older adults (≥50 years of age), stratified according to age group (50 to 59, 60 to 69, and ≥70 years). Participants received two intramuscular doses of the vaccine or placebo 2 months apart. The primary objective was to assess the efficacy of the vaccine, as compared with placebo, in reducing the risk of herpes zoster in older adults. A total of 15,411 participants who could be evaluated received either the vaccine (7698 participants) or placebo (7713 participants). During a mean follow-up of 3.2 years, herpes zoster was confirmed in 6 participants in the vaccine group and in 210 participants in the placebo group (incidence rate, 0.3 vs. 9.1 per 1000 person-years) in the modified vaccinated cohort. Overall vaccine efficacy against herpes zoster was 97.2% (95% confidence interval [CI], 93.7 to 99.0; P<0.001). Vaccine efficacy was between 96.6% and 97.9% for all age groups. Solicited reports of injection-site and systemic reactions within 7 days after vaccination were more frequent in the vaccine group. There were solicited or unsolicited reports of grade 3 symptoms in 17.0% of vaccine recipients and 3.2% of placebo recipients. The proportions of participants who had serious adverse events or potential immune-mediated diseases or who died were similar in the two groups. The HZ/su vaccine significantly reduced the risk of herpes zoster in adults who were 50 years of age or older. Vaccine efficacy in adults who were 70 years of age or older was similar to that in the other two age groups. (Funded by GlaxoSmithKline Biologicals; ZOE-50 ClinicalTrials.gov number, NCT01165177.).

    2007-01-01

    An 87-year-old woman presents with a 4-week history of urinary incontinence during which she had been treated for disseminated herpes zoster virus (HZV). On physical exam painful vesicles involving the entire vulvar region with mainly right sacral distribution were found. A catheterized volume exceeded 600 ml of retained urine after the patient failed to void spontaneously. Multichannel voiding-pressure urodynamic studies revealed an acontractile neurogenic bladder with overflow incontinence. The patient was discharged on a conservative regimen with arrangement for visiting nurse services to perform intermittent self-catheterization twice daily. Urodynamic testing was repeated 10 weeks after initial symptoms. During voiding cystometry a biphasic increase in detrusor pressure of 15 cm H2O was observed with no increase in abdominal pressure. The patient emptied 400 ml with a postvoid residual of 300 ml. Recovery from HZV-associated bladder emptying dysfunction can be achieved usually through conservative management, including intermittent self-catheterization. Complete recovery time ranges from 4 to 10 weeks.

    Full Text Available Varicella zoster virus (VZV is a DNA virus and a member of the alpha herpes viridae family, causing both primary and recurrent infection. Herpes zoster (HZ, commonly called shingles, is a distinctive syndrome caused by reactivation of VZV. This reactivation occurs when immunity to VZV declines because of aging or immune-suppression. HZ can occur at any age but most commonly affects the elderly population. HZ may affect any sensory ganglia and its cutaneous nerve. Most of the infections affect dermatomes of T3 to L2, but approximately 13% of the patients present with infections involving any of the three branches of the trigeminal nerve. Prodromal symptoms include neuropathic pain, headache, malaise, and disrupted sleep. HZ causes pruritic, localized, vesicular rash which usually appears unilaterally in the distribution of one or more adjacent sensory nerves accompanied by neuropathic pain in the affected dermatome. This is a case report of HZ infection in a 55-year-old male patient who was managed with comprehensive medical treatment.

    Full Text Available Herpes zoster of the trigeminal nerve branches caused by varicella zoster is a clinical entity consisting of erythematous macules, papules, vesicles, bullae, small ulcers and erythematous plaques, with characteristic short acute/pre-eruptive phases and long herpetic periods with pain. It is caused by reactivation of latent varicella infection. Herpes zoster is a less common endemic disease compared to varicella. During the prodromal stage, the only presenting symptom may be odontalgia, which may prove to be a diagnostic challenge for the dentist. Emergency treatment for a misdiagnosis such as trigeminal neuralgia, odontalgia, and acute pulpitis, as well as complications reported in literature such as tooth resorption, periapical lesions, periodontal destructions, and osteomyelitis may cause an irreversible damage to the patient. Hence, the dentist must be familiar with the presenting signs and symptoms in prodrome of herpes zoster infection of trigeminal nerve. The present article focuses on the pathogenesis, clinical picture, difficulties in diagnosis and management of such cases.

    Acute herpes-zoster infection is a painful dermatomal lesion that can be manifested by a wide array of neurologic symptoms. We present a 55-year-old female with non-Hodgkin's lymphoma, who developed a left sciatic pain involving the S roots. Two weeks later, the patient developed fever and vesicular rash over the left gluteal area. Herpes-zoster infection was diagnosed and confirmed by the presence of immunoglobulin M (IgM) antibodies against varicella-zoster. The pain and rash resolved, after treatment with acyclovir. In the appropriate clinical setting, sacral herpes-zoster infection ought to be considered in the differential diagnosis of new-onset sciatic pain.

    A case of sacral herpes zoster infection in a 56-year-old man with the complication of loss of urinary voiding sensation is presented. He had typical herpes zoster eruption on the left S2 dermatome, hypalgesia of the S1-S4 dermatomes, and absence of urinary voiding sensation. There was no other urinary symptom at the first medical examination. Urinary complications associated with herpes zoster are uncommon, but two types, acute cystitis and acute retention, have been recognized. No cases of loss of urinary voiding sensation due to herpes zoster have been reported. In this case, hypalgesia of the sacral dermatomes was mild compared to the marked loss of urethral sensation. This inconsistency is explained by the hypothesis that the number of urethral fibers is very small as compared to that of cutaneous fibers, therefore, urethral sensation would be more severely disturbed than cutaneous sensation.

    Full Text Available Background: Oral candidosis is an infection caused by mainly Candida albicans. Candida species are common normal flora in the oral cavity and have been reported to be present in 40% to 60% of the population. Candida is predominantly an opportunistic infectious agent. Infection frequency has increased because of the presence of both local and systemic risk factors. The elderly age and diabetes mellitus may decrease the amount of saliva (xerostomia and potentially increase the risk of colonization and secondary infection by Candida. Herpes Zoster (HZ is a manifestation of the reactivation of latent varicella zoster virus. It is characterized by unilateral, painful, vesicular rash with a dermatomal distribution. The clinical manifestations of this disease can erupt to the skin and mucous membrane. If maxillary nerve is involved, the lesion can appear on unilateral facial skin and oral mucous membrane. Purpose: The purpose of this paper is to report and discuss the difficulties in managing the oral candidosis in elderly patient (57 year old male who suffered from maxillary Herpes Zoster and diabetes mellitus. Case management: At first, the patient was treated with 2% chlorhexidine gluconate and mycostatin oral suspension as topical antimycotic and reffered to dermathology clinic for viral infection treatment, however the oral candidosis did not improved. Subsequently, ketokonazole tablet was given three times daily for three weeks and regulated blood glucose level. In systemic antifungi (ketokonazole treatment the oral candidosis disappeared. Conclusion: In this case, it is conclude that the management of oral candidosis are adequate, antiviral, blood glucose level regulating and systemic antifungal therapy.

    Full Text Available Herpes zoster (HZ is caused by reactivation of the varicella zoster virus. Its main risk factor is increasing age and comorbidities. There are limited data on the characteristics of HZ in South America, especially in the elderly. We analyzed epidemiological and clinical characteristics of 340 patients over 60 years assisted for HZ, between June 2013 and May 2014. The average age was 74 years (60-100, 62% (210 had thoracic location; 75% (255 of the initial consultations were held in guards; 68% (143 had pain and vesicles, and 4% (14 only pain at baseline. Pain persisted after finishing the episode in 41% (139. The diagnosis was made between 1 and 3 days from the beginning of the episode in 53% (180 patients. Average number of visits per episode was 3.6 (1-24. Antiviral treatment was supplied to 91% (309; however it was inadequate in dose or time in 49.1% (167 cases. Pain treatment was indicated in 66% (224. Most frequently used drugs (alone or in combination were non-steroidal painkillers (43%, 146, pregabalin (30%, 102, opiates (24%, 82, and steroids (12%, 41; 9% (31 presented comorbidities; 27% (126 experienced pain after the ending of the episode, with an average duration of 138.7 days. In general, diagnosis was done late, making it difficult to use antivirals correctly. The presence of pain was more frequent than reported in other publications, however there are few data in this age group

    2016-12-01

    Full Text Available Reactivated varicella-zoster virus (VZV, which lies latent in the dorsal root ganglions and cranial nerves before its reactivation, is capable of causing herpes zoster (HZ, but the specific mechanism of virus reactivation and latency remains unknown. It was proposed that circulating microRNAs (miRNAs in body fluids could potentially indicate infection. However, the connection between herpes zoster and circulating miRNAs has not been demonstrated. In this study, 41 HZ patients without superinfection were selected. The serum miRNA levels were analyzed by TaqMan low density array (TLDA and confirmed individually by quantitative reverse transcription PCR (RT-qPCR analysis. Thirty-five age-matched subjects without any infectious diseases or inflammation were selected as controls. The results showed that the serum miRNA expression profiles in 41 HZ patients were different from those of control subjects. Specifically, 18 miRNAs were up-regulated and 126 were down-regulated more than two-fold in HZ patients compared with controls. The subsequent confirmation of these results by qRT-PCR, as well as receiver operating characteristic (ROC curve analysis, revealed that six kinds of miRNAs, including miR-190b, miR-571, miR-1276, miR-1303, miR-943, and miR-661, exhibited statistically significant enhanced expression levels (more than four-fold in HZ patients, compared with those of healthy controls and herpes simplex virus (HSV patients. Subsequently, it is proposed that these circulating miRNAs are capable of regulating numerous pathways and some may even participate in the inflammatory response or nervous system activity. This study has initially demonstrated that the serum miRNA expression profiles in HZ patients were different from those of uninfected individuals. Additionally, these findings also suggest that six of the altered miRNA could be potentially used as biomarkers to test for latent HZ infection.

    A 19-year-old girl with a history of precursor B acute lymphoblastic leukemia in remission presented with fever, headache, and a skin rash. Cerebrospinal fluid (CSF) examination reported pleocytosis with blast-like cells concerning for a central nervous system leukemic relapse. After the patient showed significant improvement on intravenous acyclovir, a repeat lumbar puncture revealed normalization of CSF. The abnormal CSF cells were reviewed and ultimately determined to be activated and atypical lymphocytes. The patient recovered uneventfully. Atypical lymphocytes resembling leukemic blasts are an unusual finding in viral meningitis. Varicella zoster virus reactivation should be considered during initial evaluation for central nervous system relapse of leukemia.

    Full Text Available Background: Even though herpes zoster is a common condition its incidence and pattern of occurrence in the era of HIV disease is significant. Aim: To analyze the incidence, pattern of occurrence and evolution of herpes zoster with special attention to provocative factors if any. Materials and Method s: This was an analytical study conducted for 2 years based on a preformed proforma containing preliminary information, a detailed clinical evaluation regarding the segment of involvement, morphology, pattern of lesions, complications, disseminations etc. and investigations to establish provocative factors if any. Results: Incidence of herpes zoster was mainly in the fourth and third decades of life. A definite history of chicken pox was present in only 63.4% cases. In the majority (70% herpes zoster occurred spontaneously. In 30% cases, immunosuppression due to chemotherapy, malignancy, HIV infection, diabetes mellitus were observed. The commonest segment affected was thoracic (42.4% followed by cranial (28.2% and cervical (12.1%. Majority resolved in 7-14 days except immunosuppressed. 34.6% of the patients had complications such as secondary bacterial infection, post herpetic neuralgia, and motor weakness. Ten patients had HIV infection as a provocative factor. Conclusion: The results of incidence and clinical pattern of herpes zoster is almost parallel to the previous studies. Any factors of immunosuppression should be checked, especially HIV, particularly in disseminated and long-lasting cases.

    AIM: To report a case of superior orbital fissure syndrome (SOFS) in a patient with herpes zoster ophthalmicus (HZO). MATERIALS AND METHODS: A case report. RESULTS: A 71-year-old male with HZO presented acutely to accident and emergency complaining of right vision loss, double vision and drowsiness. The right visual acuity was counting fingers. There was no relative afferent pupillary defect. He had interstitial keratitis, ptosis, proptosis and total ophthalmoplaegia. The signs indicated HZO complicated by SOFS. Brain imaging and lumbar puncture confirmed the diagnosis of varicella zoster encephalitis. Systemic acyclovir and prednisolone led to recovery of visual acuity and ocular motility in addition to resolution of his proptosis and ptosis. CONCLUSION: SOFS is a rare complication of herpes zoster infection. With the appropriate treatment and follow-up, patients may be reassured that recovery of their visual acuity and ocular motility will occur.

    Mankesh Lal Gambhir

    2014-04-01

    Full Text Available “Wolf’s isotopic response” describes the occurrence of a new skin disorder at the site of another, unrelated and already healed skin disease. In most cases of isotopic response, the initial dermatosis is herpes zoster, herpes simplex, varicella, thrombophlebitis, scrofuloderma and striae distense. The most frequent second dermatoses are granulomatous reactions, particularly granuloma annulare, and lichenoid diseases. Various etiological reasons including viral, immunologic, neural and vascular have been put forth. We report here a case in which the second disease was herpes zoster that appeared over the same dermatomes of pre-existing segmental vitiligo. The occurrence of vitiligo as first and herpes zoster as second disease in the “Wolf’s isotopic response” has not, to the best of our knowledge, been reported previously.

    Raina MacIntyre

    Full Text Available Increasing trends in incidence of herpes zoster (HZ have been reported in Australia and internationally. This may reflect the impact of childhood VZV vaccination programs introduced universally in Australia in late 2005. The objective of this study was to evaluate changes in incidence of HZ and PHN in Australia over time, and associated healthcare resource utilisation.Australian data on general practice (GP encounters for HZ, specific antiviral prescribing data from the pharmaceutical benefits scheme, emergency department presentations from the states of NSW and Victoria and national hospitalisation data for HZ were analysed for time trends using regression models. Two time periods (2000-2006 and 2006-2013 were compared which correspond broadly with the pre- and post- universal VZV vaccination period.All data sources showed increasing rates of HZ with age and over time. The GP database showed a significant annual increase in encounters for HZ of 2.5 per 100,000 between 1998 and 2013, and the rates of prescriptions for HZ increased by 4.2% per year between 2002 and 2012. In the 60+ population HZ incidence was estimated to increase from 11.9 to 15.4 per 1,000 persons using GP data or from 12.8 to 14.2 per 1,000 persons using prescription data (p<0.05, between the two periods. Hospitalisation data did not show the same increasing trend over time, except for the age group ≥80 years. Most emergency visits for HZ were not admitted, and showed significant increases over time.The burden of HZ in Australia is substantial, and continues to increase over time. This increase is seen both pre- and post-universal VZV vaccination in 2005, and is most prominent in the older population. The substantial burden of HZ, along with ageing of the Australian population and the importance of healthy ageing, warrants consideration of HZ vaccination for the elderly.

    Acute urinary retention in women is uncommon. A 63 year old woman presented with suprapubic pain, a palpable bladder, and multiple grouped vesicles on the right buttock. Catheterisation showed a residual of 2000 ml. A case is reported of acute urinary retention secondary to herpes zoster infection of the sacral nerves (S2-4).

    Herpes zoster infection involving the sacral dermatomes has been associated with bladder dysfunction and, although rarely, with acute urinary retention. Less than 150 cases have been reported in the literature. After reviewing our institute's chart records covering a period of time dating from 1991 to 2001, we found that three of our patients had developed acute urinary retention following herpes zoster skin lesions of the S2-4 dermatomes. Herein we report our findings. These three patients had previously been found to have normal voiding status. However, at the time of complaint urodynamic studies revealed detrusor areflexia or detrusor hyporeflexia with decreased sensation of bladder filling. After micturation recovery, repeat urodynamic studies revealed detrusor pressure and bladder sensation recovery. After one to six weeks of treatment, all three patients could void spontaneously without catheterization. We found that, when treated with antiviral medication, supportive analgesics, and temporary urinary drainage, which included urethral catheterization and suprapubic cystostomy, acute urinary retention associated with herpes zoster has a generally favorable prognosis. In other words, we found that in spite of its rarity, herpes zoster induced neuropathic bladder dysfunction is reversible when treated appropriately.

    Voiding dysfunction is a rare but important complication of lumbo-sacral herpes zoster. Although the symptoms are transient, the clinical impact on immunocompromised patients cannot be overlooked. To clarify the time course of voiding dysfunction in herpes zoster, 13 herpes zoster patients with voiding dysfunction were retrospectively analyzed. Of 13 patients, 12 had background disease, and six of these were hematopoietic malignancies; four of these patients were hematopoietic stem cell transplant (HSCT) recipients. Ten patients had sacral lesions, two had lumbar, and one had thoracic lesions. Interestingly, patients with severe rash, or with hematopoietic malignancy had later onset of urinary retention than did patients with mild skin symptoms (Mann-Whitney U analysis, P = 0.053) or with other background disease (P = 0.0082). Patients with severe skin rash also had longer durations (P = 0.035). In one case, acute urinary retention occurred as late as 19 days after the onset of skin rash. In immune compromised subjects, attention should be paid to patients with herpes zoster in the lumbo-sacral area for late onset of acute urinary retention even after the resolution of skin symptoms.

  15. Risk of herpes zoster and family history: A Meta-analysis of case–control studies

    Full Text Available Background: Herpes zoster (HZ results from the reactivation of latent varicella zoster virus (VZV residing in dorsal root and cranial nerve ganglia. Advanced age and dysfunctional cell-mediated immune responses are well-established risk factors for VZV reactivation. There have been recent interests in whether there is an increased risk of the disease associated with a positive family history. Aims and Objectives: We aimed to conduct a meta-analysis to evaluate the association between HZ infection and family history. In addition, we investigated the dose-response relationship between HZ infection and the number of relatives with a history of HZ. Materials and Methods: Observational studies were searched from MEDLINE, EMBASE, and Cochrane Central Register from inception to April 15, 2015. The Meta-analysis of Observational Studies in Epidemiology guidelines were followed in conducting this study. To estimate the pooled odds ratio, random-effects model of DerSimonian and Laird was used. Heterogeneity between studies was assessed using the I2 statistic. A dose-response meta-analysis with studies that reported appropriate data were done using the generalized least squares for trend method. Results: Five studies, yielding a total of 4169 subjects, were identified for meta-analysis. Cases with HZ were 3.03 (95% confidence interval [CI]: 1.86–4.94, P < 0.001 and 3.27 (95% CI: 1.75–6.10, P < 0.001 times more likely to report the first-degree relatives and total relatives with a history of HZ, respectively. A significant positive dose-response relationship between the risk of HZ infection and the number of relatives with a history of HZ was also demonstrated (P < 0.001. Conclusions: This meta-analysis demonstrated that family history is a significant risk factor for HZ infection. This risk has a dose-response relationship with the number of relatives with a history of HZ.

    Herpes zoster (HZ) is caused by reactivation of the varicella-zoster virus (VZV) and mainly affects individuals aged ≥50 years. The forthcoming European launch of a vaccine against HZ (Zostavax®) prompts the need for a better understanding of the epidemiology of HZ in Europe. Therefore the aim of this systematic review was to summarize the available data on HZ incidence in Europe and to describe age-specific incidence. The Medline database of the National Library of Medicine was used to conduct a comprehensive literature search of population-based studies of HZ incidence published between 1960 and 2010 carried out in the 27 member countries of the European Union, Iceland, Norway and Switzerland. The identified articles were reviewed and scored according to a reading grid including various quality criteria, and HZ incidence data were extracted and presented by country. The search identified 21 studies, and revealed a similar annual HZ incidence throughout Europe, varying by country from 2.0 to 4.6/1 000 person-years with no clearly observed geographic trend. Despite the fact that age groups differed from one study to another, age-specific HZ incidence rates seemed to hold steady during the review period, at around 1/1 000 children European Union Member States and to monitor the impact of VZV immunization on the epidemiology of HZ. Available data in Europe have shortcomings which make an accurate assessment of HZ incidence and change over time impossible. However, data are indicative that HZ incidence is comparable, and increases with age in the same proportion across Europe.

Material y métodos: Estudio prospectivo observacional realizado entre agosto de 2005 y agosto de 2006. Se incluyeron pacientes adultos con diagnóstico de herpes zoster atendidos en los diferentes servicios del Hospital Nacional Cayetano Heredia. Un cuestionario de características clínicas y factores de riesgo asociados con infección por HTLV-1 y VIH fue completado previo a la toma de muestra. Se excluyeron los pacientes con resultados positivos previos para HTLV-1 y HIV. Resultados: Se incluyeron 44 pacientes, la edad promedio fue 48,1 ± 19,5; 24/44 (55% fueron mujeres. Infección solo por VIH se encontró en 4/44 (9% pacientes, todos menores de 35 años, mientras que infección solo por HTLV-1 se encontró en 2/44 (5% pacientes, todas mujeres mayores de 50 años. Un caso de infección dual fue encontrado en una mujer de 56 años. La tasa de infección por HTLV-1 fue 25% (3/12 en mujeres mayores de 50 años con compromiso de múltiples dermatomas. Conclusiones: En nuestro escenario, la infección por HTLV-1 es ligeramente mas frecuente en mujeres mayores de 50 años con herpes zoster. Por ello, el despistaje de HTLV-1 debe ser recomendado en este grupo etario, mientras que el despistaje de VIH es aún particularmente importante en pacientes jóvenes.(Rev Med Hered 2011;22:98-102.

    The US Advisory Committee on Immunization Practices has recently recommended a new vaccine against herpes zoster (shingles) for routine use in adults aged > or =60 years. However, estimates of the cost effectiveness of this vaccine vary widely, in part because of gaps in the data on the value of preventing herpes zoster. Our aims were to (i) generate comprehensive information on the value of preventing a range of outcomes of herpes zoster; (ii) compare these values among community members and patients with shingles and post-herpetic neuralgia (PHN); and (iii) identify clinical and demographic characteristics that explain the variation in these values. Community members drawn from a nationally representative survey research panel (n = 527) completed an Internet-based survey using time trade-off and willingness-to-pay questions to value a series of scenarios that described cases of herpes zoster with varying pain intensities (on a scale of 0 to 10, where 0 represents no pain and 10 represents the worst imaginable pain) and duration (30 days to 1 year). Patients with shingles (n = 382) or PHN (n = 137) [defined as having symptoms for > or =90 days] from two large healthcare systems completed telephone interviews with similar questions to the Internet-based survey and also answered questions about their current experience with herpes zoster. We constructed generalized linear mixed models to evaluate the associations between demographic and clinical characteristics, the length and intensity of the health states and time trade-off and willingness-to-pay values. In time trade-off questions, community members offered a mean of 89 (95% CI 24, 182) discounted days to avoid the least severe scenario (pain level of 3 for 1 month) and a mean of 162 (95% CI 88, 259) discounted days to avoid the most severe scenario (pain level of 8 for 12 months). Compared with patients with shingles, community members traded more days to avoid low-severity scenarios but similar numbers of days

    Some infectious diseases have been found to be associated with cognitive impairment and dementia. However, the relationship between herpes zoster and dementia has received little attention. This study aimed to investigate this association as well as associations of antiviral treatments for herpes zoster and incident dementia using a large national sample. Cases were identified from the Taiwan National Health Insurance Research Database with a new diagnosis of herpes zoster (ICD-9-CM code: 053) between 1997 and 2013. Each identified individual with a case of herpes zoster was compared with 1 sex-, age-, and residence-matched control subject. Both groups were followed until the first diagnosis of dementia (ICD-9-CM codes: 290.0 to 290.4, 294.1, 331.0 to 331.2, and 331.82), withdrawal from the registry, or the end of 2013. Cox regression analyses and competing risk model were applied, adjusting for sex, age, residence, depression, autoimmune disease, ischemic stroke, traumatic brain injury, alcohol use disorder, and antiviral treatments for herpes zoster to evaluate the risk of interest. A total of 39,205 cases with herpes zoster were identified. Of the 78,410 study and comparison subjects, 4,204 were diagnosed as having dementia during a mean (SD) follow-up period of 6.22 (4.05) years. Herpes zoster was associated with a slightly increased risk of dementia in the fully adjusted model (hazard ratio [HR] = 1.11; 95% CI, 1.04-1.17). Prescriptions of antiviral therapy were associated with a reduced risk of developing dementia following the diagnosis of herpes zoster (HR = 0.55; 95% CI, 0.40-0.77). Herpes zoster was associated with an increased risk of dementia, independent of potential confounding factors. Antiviral treatment might be protective in preventing dementia in patients with herpes zoster. © Copyright 2017 Physicians Postgraduate Press, Inc.

    Symptom of herpes zoster is sometimes difficult to distinguish from sciatica induced by spinal diseases, including lumbar disc herniation and spinal canal stenosis. Here we report a case of sciatica mimicking lumbar canal stenosis. A 74-year-old Chinese male patient visited our hospital for left-sided sciatic pain upon standing or walking for 5 min of approximately 1 month's duration. At the first visit to our hospital, there were no skin lesions. A magnetic resonance imaging showed spinal canal stenosis between the 4th and 5th lumbar spine. Thus, we diagnosed the patient with sciatica induced by spinal canal stenosis. We considered decompression surgery for the stenosis of 4th and 5th lumbar spine because conservative therapy failed to relieve the patient's symptom. At that time, the patient complained of a skin rash involving his left foot for several days. A vesicular rash and erythema were observed on the dorsal and plantar surfaces of the great toe and lateral malleolus. The patient was diagnosed with herpes zoster in the left 5th lumbar spinal nerve area based on clinical findings, including the characteristics of the pain and vesicular rash and erythema in the 5th lumbar spinal dermatome. The patient was treated with famciclovir (1,500 mg/day) and non-steroidal anti-inflammatory drugs. After 1 week of medication, the skin rash resolved and pain relief was obtained. In conclusion, spinal surgeons should keep in mind herpes zoster infection as one of the possible differential diagnoses of sciatica, even if there is no typical skin rash.

    Retinal infections caused by the varicella-zoster virus (VZV) have been reported in immunocompetent and immunocompromised individuals. Two cases of a VZV-related retinitis are described with the characteristic features of the recently described progressive outer retinal necrosis (PORN) syndrome. Both patients suffered from the acquired immunodeficiency syndrome (AIDS) with greatly reduced peripheral blood CD4+ T lymphocyte counts, and presented with macular retinitis without vitritis. The disease was bilateral in one case and unilateral in the other. The clinical course was rapidly progressive with widespread retinal involvement and the development of rhegmatogenous retinal detachment with complete loss of vision in the affected eyes despite intensive intravenous antiviral therapy. VZV DNA was identified in vitreous biopsies, by molecular techniques based on the polymerase chain reaction (PCR), in both patients. At present, the use of very high-dose intravenous acyclovir may be the best therapeutic option in these patients for whom the visual prognosis is poor. Intravitreal antiviral drugs could also contribute to the management of these cases.

Aspirin and simvastatin were prescribed, but the patient suffered a stepwise deterioration the following days, with new areas of infarction on brain imaging. Despite no evidence of cardiac or large vessel embolic sources, anticoagulation was started empirically 6 days after stroke onset. One week later, symptomatic hemorrhagic transformation occurred. The diagnosis of VZV vasculopathy was then considered, and treatment with acyclovir and prednisolone was started with no further vascular events. Cerebrospinal fluid analysis and digital subtraction angiography findings corroborated the diagnosis. The patient was discharged to the rehabilitation center with a modified Rankin scale (mRS score of 4. On the 6-month follow-up, she presented only a slight disability (mRS score 2. In conclusion, VZV vasculopathy needs to be considered in young adults with stroke. A high index of suspicion and early treatment seem to be important to minimize morbidity and mortality. Anticoagulation should probably be avoided in stroke associated with VZV vasculopathy.

    Full Text Available Measurement of metabolic processes in lymphocytes in Varicella zoster infection showed highly increased intercellular glycolisys activity with functional cellular overload. Same time, we discovered decreased level of intensivity of first stages of TCC, that rules to lower cycle energetic efficiency and intense metabolitsaminoacides intake for TCC, guiding to high aminoacides transport to lymphocytes. Usage of succinic acid and its salts gives more substrates for TCC, increasing its energetic efficiency and lymphocytes functional activity.

    Herpes zoster (HZ) infection has been reported as a rare cause of acute urinary retention. HZ infection involving sacral, thoracolumbar, and rarely high thoracic dermatomes is believed to occasionally cause motor and sensory neuropathy of the bladder. This is specifically achieved by the interruption of the detrusor reflex causing subsequent bladder atonia. As the course and management of this entity is quite benign, HZ should remain a diagnostic consideration in the management of urinary retention. We report a case of acute urinary retention of approximately 2.5 liters associated with HZ infection and review the proposed pathogenesis and therapeutic considerations in the management of this entity.

    Herpes zoster is an important problem of public health especially among the elderly in Spain. A population-based retrospective epidemiological study to estimate the burden of herpes zoster requiring hospitalization in the Canary Islands, Spain was conducted by using data from the national surveillance system for hospital data, Conjunto Mínimo Básico de Datos. Records of all patients admitted to hospital with a diagnosis of herpes zoster in any position and cases of primary diagnosis (ICD-9-MC codes 053.0-053.9) during a 10-year period (2005-2014), were selected. A total of 1088 hospitalizations with a primary or secondary diagnosis of herpes zoster were identified during the study period. Annually there were 6.99 hospitalizations by herpes zoster per 100,000 population. It increases with age reaching a maximum in persons ≥85 years of age (43.98 admissions per 100,000). Average length of hospitalization was 16 days and 73 patients died, with a case-fatality rate of 4.03%. In 22% of the cases hospitalized, herpes zoster was the primary diagnosis. The hospitalization burden of herpes zoster in adults in the Canary Islands was still important during the last decade and justify the implementation of preventive measures, like vaccination in the elderly or other high risk groups to reduce the most severe cases of the disease.

    Herpes zoster (HZ) is a vaccine-preventable disease caused by reactivation of the varicella-zoster virus. Unfortunately, formulation of recommendations on routine immunization is hampered by a lack of data on disease burden, since most countries do not record cases of HZ in the general population. We developed and validated an algorithm to identify HZ based on routinely collected registry data and used it to quantify HZ occurrence and risk factors in Denmark prior to marketing of the HZ vaccine. We included patients aged ≥40years with a first-time systemic Acyclovir, Valacyclovir, or Famciclovir prescription or a hospital-based HZ diagnosis in the Danish nationwide health registries during 1997-2013. In a validation substudy (n=176), we computed the proportion of persons with HZ among patients who redeemed antiviral prescriptions. In a cohort study, we computed age-specific rates of HZ (45,297,258 person-years). In a case-control study, we then computed odds ratios (ORs) for common chronic diseases and immunosuppressive factors among HZ cases (n=189,025) vs. matched population controls (n=945,111). Medical record review confirmed HZ in 87% (95% confidence interval: 79-93%) of persons ≥40years who dispensed antivirals at doses recommended for HZ. HZ rates increased from 2.15/1000 person-years in 40-year-olds to 9.45/1000 person-years in 95-year-olds. Rates were highest in women. HZ was diagnosed during hospitalization among 3.5%. As expected, persons with severe immunosuppressive conditions had the highest ORs of HZ (between 1.82 and 4.12), but various autoimmune diseases, asthma, chronic kidney disease, and inhaled glucocorticoids were also associated with increased ORs (between 1.06 and 1.64). This algorithm is a valid tool for identifying HZ in routine healthcare data. It shows that HZ is common in Denmark, especially in patients with certain chronic conditions. Prioritized vaccination of such high-risk patients might be an option in countries considering

    Full Text Available Introduction: VZV is an exclusively human pathogen. The primary infection typically occurs during childhood and causes varicella. As with other members of the herpes viruses’ family, VZV is noninfectious in its latent form but can reactivate at a later time to form intact virions in the involved sensory neurons. These virions then migrate to the skin through axons, spread from cell to cell, and penetrate the epidermis.Case Report: In this case a 72 years old woman with history of diabetes mellitus and hypertension is reported hospitalized because of urinary retention, weakness and parestesia in the right leg, complicated with vesiculoulcerative lesions in sacral area with distribution to the right buttock and vagina. L.P was done to confirm inflammatory radicopathy that showed aseptic meningitis and therapy started with acyclovir and prednisolone. Patient got well and discharged from the hospital.Conclusion: Motor weakness in noncranial nerve is one of the zoster complications known as zoster paresis. Weakness begins suddenly 2-3 weeks after rash and progresses to extremities. In this case 3 weeks after rash, nerve complications were observed. We recommend to do paresthesia examination of skin for eruption in all patients presented with paresis.

    During a 3-month period, 131 cases of herpes zoster were diagnosed in Kigali, Rwanda. There were 46 female and 85 male patients. Mean age was 29 years (range 1-66). An unusually high proportion of patients presented with cranial and sacral nerve localisation of their cutaneous lesions. 55/131 patients (42%) had involvement of more than one dermatome. None of the patients had an underlying condition known to favour herpes zoster. 120/131 (92%) had antibodies to HIV detected by an immunoenzymatic assay (EIA) and indirect immunofluorescence. 92/125 adult patients (74%) had no sign or symptom related to HIV infection other than herpes zoster. This study suggests that herpes zoster in Central Africa is an early and readily detectable manifestation of HIV-induced immunosuppression.

    Varicella-zoster virus causes herpes zoster (HZ) along specific dermatomes, but the effects of age and sex on HZ distribution are unclear. We investigated the age- and sex-dependent distribution characteristics of HZ. Patients with HZ were monitored by members of the Miyazaki Dermatologist Society. Questionnaires containing information on age, sex, and dermatome distribution and lesion specimens from 2730 patients were collected, and 2508 PCR-diagnosed cases were analyzed. The ratio of lesions in the thoracic area to lesions in the whole body decreased with age, whereas those of other areas increased. HZ incidence increased with age to about four times that of the basic incidence in the dermatome areas at age 0-29 years; the incidence in the trigeminal area in both sexes increased 11-fold, and the incidence in the thoracic and lumbosacral areas increased in females more than in males. Furthermore, the fact that the highest incidence was found along the first branch of the trigeminal nerve suggests an association with long-term ultraviolet ray exposure. Segmental dermatomes comprising thoracic 10-lumbar 1/sacral 2-4 and thoracic 5-6 were significantly more frequently affected in female patients at age 50-59 years and are consistent with areas of obstetric anesthesia for childbirth and of breastfeeding, respectively. HZ incidence increased with age; moreover, exposure to ultraviolet rays, childbirth, and breastfeeding might increase the incidence at specific dermatomes in older individuals. This study provides important information on the etiology of HZ. Copyright © 2018 Japanese Society for Investigative Dermatology. Published by Elsevier B.V. All rights reserved.

    Retrospective analysis of 210 cases of patients with Hodgkin's disease revealed an overall incidence of herpes zoster varicella of 9.5 per cent. Patients with the mixed cellular histological subtype showed a significantly increased (p < 0.05) risk as compared with the total population. More than 90 per cent of the herpes zoster varicella infections occurred after termination of treatment; a combination of radiotherapy with chemotherapy proved to be a predisposing factor. (Auth.)

    To evaluate whether the use of personal selling, in combination with other promotional techniques, could improve patient commitment to receive the targeted intervention of herpes zoster vaccine (Zostavax-Merck). Two locally owned grocery store chain pharmacies in the Kansas City, MO, metropolitan area (Price Chopper Pharmacy 11 [PC11] and Price Chopper Pharmacy 36 [PC36]). Price Chopper Pharmacy employs pharmacists who are able to administer vaccinations to patients within the dispensing workflow. Passive signage promoting zoster vaccine was placed at both PC11 and PC36. Personal selling by pharmacy staff to targeted patients was implemented at PC36, where patients were encouraged to receive zoster vaccine at prescription pick up and/or by personalized letter. Primary measures included comparison of the number committing to receive zoster vaccine at either pharmacy, comparison of patient perceptions regarding each pharmacy's promotion of zoster vaccine, and pharmacy staff time spent identifying targeted patients and performing personal selling activities. 90 of 745 targeted patients (12.1%) at PC36 made commitments to receive zoster vaccine compared with 9 of 614 (1.5%) at PC11 (P < 0.001). The barrier of "Dr. hasn't told me I need it" was reduced for PC36 patients (P < 0.05). Patients receiving vaccination had a more favorable attitude toward receiving zoster vaccine than unvaccinated patients (P < 0.01). Among unvaccinated patients, those at PC36 had a more favorable attitude toward receiving zoster vaccine after interacting with a pharmacist (P < 0.05). Personal selling increased patient commitment to receiving a targeted intervention significantly. By using personal selling, pharmacists resolved barriers to immunization.

    Postherpetic neuralgia is the most common complication of herpes zoster. Identifying predictors for postherpetic neuralgia may help physicians screen herpes zoster patients at risk of postherpetic neuralgia and undertake preventive strategies. Peptic ulcer has been linked to immunological dysfunctions and malnutrition, both of which are predictors of postherpetic neuralgia. The aim of this retrospective case-control study was to determine whether adult herpes zoster patients with peptic ulcer were at greater risk of postherpetic neuralgia. Adult zoster patients without postherpetic neuralgia and postherpetic neuralgia patients were automatically selected from a medical center's electronic database using herpes zoster/postherpetic neuralgia ICD-9 codes supported with inclusion and exclusion criteria. Consequently, medical record review was performed to validate the diagnostic codes and all pertaining data including peptic ulcer, Helicobacter pylori (H. pylori) infection and ulcerogenic medications. Because no standard pain intensity measurement exists, opioid usage was used as a proxy measurement for moderate to severe pain. In total, 410 zoster patients without postherpetic neuralgia and 115 postherpetic neuralgia patients were included. Multivariate logistic regressions identified 60 years of age and older, peptic ulcer and greater acute herpetic pain as independent predictors for postherpetic neuralgia. Among etiologies of peptic ulcer, H. pylori infection and usage of non-selective nonsteroidal anti-inflammatory drugs were significantly associated with the increased risk of postherpetic neuralgia; conversely, other etiologies were not significantly associated with the postherpetic neuralgia risk. In conclusion, 60 years of age and older, peptic ulcer and greater acute herpetic pain are independent predictors for postherpetic neuralgia in adult herpes zoster patients. © 2014 Wiley Periodicals, Inc.

    Herpes zoster is a common illness that can lead to serious morbidity. There is now evidence that HIV-infected patients who have been treated with antiretroviral therapy are at greater risk of developing herpes zoster not when they are severely immunocompromised but, paradoxically, when their immune system is recovering. This is a manifestation of the immune reconstitution inflammatory syndrome. The objectives of this report are to (1) inform health care providers that HIV-infected patients may develop multiple infectious, autoimmune, and oncological manifestations after treatment with antiretroviral medication, as they have immune system reconstitution, and (2) discuss herpes zoster, one of the possible manifestations. The patient is a 68-year-old HIV-positive man who presented with herpes zoster after being treated with highly active antiretroviral therapy (HAART) when his immune system was recovering, not when he was most immunosuppressed. Emergency department physicians should be aware that HIV-infected patients treated with HAART may have clinical deterioration despite immune system strengthening. This immune reconstitution inflammatory syndrome can present with infectious, autoimmune, or oncological manifestations. Our case patient, an HIV-positive man with immune system recovery after treatment with HAART, presented with an infectious manifestation, herpes zoster.

  11. Functional decline and herpes zoster in older people: an interplay of multiple factors.

    Science.gov (United States)

    2015-12-01

    Herpes zoster is a frequent painful infectious disease whose incidence and severity increase with age. In older people, there is a strong bidirectional link between herpes zoster and functional decline, which refers to a decrement in ability to perform activities of daily living due to ageing and disabilities. However, the exact nature of such link remains poorly established. Based on the opinion from a multidisciplinary group of experts, we here propose a new model to account for the interplay between infection, somatic/psychiatric comorbidity, coping skills, polypharmacy, and age, which may account for the functional decline related to herpes zoster in older patients. This model integrates the risk of decompensation of underlying disease; the risk of pain becoming chronic (e.g. postherpetic neuralgia); the risk of herpes zoster non-pain complications; the detrimental impact of herpes zoster on quality of life, functioning, and mood; the therapeutic difficulties due to multimorbidity, polypharmacy, and ageing; and the role of stressful life events in the infection itself and comorbid depression. This model underlines the importance of early treatment, strengthening coping, and vaccine prevention.

    Full Text Available Herpes zoster ophthalmicus and HIV are serious health problems. We report a case of a 37-year-old woman who presented to the Korle-Bu Teaching Hospital with dyspnea and facial cellulitis, and a diagnosis 5 days prior of dental cellulitis made at a district hospital. Investigations revealed that the facial cellulitis was secondary to herpes zoster infection involving the ophthalmic division of the left trigeminal nerve. The patient responded well to oral acyclovir but developed postherpetic neuralgia. During the course of treatment, she was also diagnosed to be HIV-1 positive and was referred for further management. This case represents a unique report in which the patient presented to the hospital with symptoms of cellulitis suggestive of underlying dental infection but was later diagnosed with both herpes zoster ophthalmicus and an underlying HIV infection. Atypical presentations of herpes zoster can occur in HIV/AIDS. Signs of herpes zoster infection with cellulitis should alert the clinician that the patient may have a possible underlying immunosuppressive disease. The population must be educated regarding the importance of early presentation and careful compliance with treatment as well as regular follow-ups.

    Patients with inflammatory bowel disease (IBD) might be at increased risk for herpes zoster infection. We sought to quantify the risk of herpes zoster in patients with IBD and evaluate the effects of IBD and IBD medications on the risk of herpes zoster. We conducted 2 retrospective studies of populations of Veterans, from January 2000 through June 2016. In study 1, we compared the incidence of herpes zoster among patients with IBD receiving 5-ASA alone vs matched patients without IBD. In study 2, we compared the incidence of herpes zoster among patients with IBD treated with only 5-ASA, with thiopurines, with antagonists of tumor necrosis factor (TNF), with a combination of thiopurines and TNF antagonists, and with vedolizumab. We used multivariable Cox regression to estimate the hazard ratios and 95% CIs for herpes zoster associated with IBD in study 1 and with different treatments in study 2. We also estimated the incidence rate of herpes zoster based on age and IBD medication subgroups. Compared to no IBD, ulcerative colitis (UC) and Crohn's disease (CD) were each associated with significantly increased risk of herpes zoster infection. In multivariable Cox regression (compared to no IBD), UC, CD, or IBD treated with 5-ASA treatment alone was associated with significantly increased risk of herpes zoster, with adjusted HRs (AHR) of 1.81 for UC (95% CI, 1.56-2.11), 1.56 for CD (95% CI, 1.28-1.91), and 1.72 for treated IBD (95% CI, 1.51-1.96). In multivariable Cox regression analysis, compared to exposure to 5-ASA alone, exposure to thiopurines (AHR, 1.47; 95% CI, 1.31-1.65) or a combination of thiopurines and TNF antagonists (AHR, 1.65; 95% CI, 1.22-2.23) was associated with increased risk of herpes zoster. However, exposure to TNF antagonists alone (AHR, 1.15; 95% CI, 0.96-1.38) was not associated with increased risk of herpes zoster. The incidence rates of herpes zoster in all age groups and all IBD medication subgroups were substantially higher than that in the

While it is optimal to give herpes zoster vaccine prior to initiation of therapy clinical circumstances may not always allow this. To determine the safety of giving herpes zoster vaccine while patients are on anti-TNF therapy. We conducted a retrospective cohort study involving IBD patients who were followed in the Veterans Affairs (VA) healthcare system between 2001 and 2016. Patients who received herpes zoster vaccine while on anti-TNF medication were identified through vaccination codes and confirmed through individual chart review. Our outcome of interest was development of HZ between 0 and 42 days after herpes zoster vaccine administration. Fifty-six thousand four hundred and seventeen patients with IBD were followed in the VA healthcare system. A total of 59 individuals were on anti-TNF medication when they were given herpes zoster vaccine, and amongst them, 12 (20%) were also taking a thiopurine. Median age at the time of herpes zoster vaccine was 64.9 years and 95% of patients had a Charlson Comorbidity Index of ≥2. Median number of encounters within 42 days after receiving herpes zoster vaccine was two. No case of HZ was found within 0-42 days of HZV administration. Our data suggest that co-administering the herpes zoster vaccine to patients who are taking anti-TNF medications is relatively safe. This study significantly expands the evidence supporting the use of herpes zoster vaccine in this population, having included an elderly group of patients with a high Charlson Comorbidity Index who are likely at a much higher risk of developing HZ. © 2017 John Wiley & Sons Ltd.

    Full Text Available Purpose: To evaluate the diagnostic usefulness of enzyme linked immuno-sorbent assay (ELISA in single serum samples to associate herpes simplex virus (HSV, varicella zoster virus (VZV or cytomegalovirus (CMV with viral retinitis as against polymerase chain reaction (PCR on intraocular specimens. It was also designed to study the seroprevalence in normal healthy individuals, and the genomic prevalence of HSV, VZV and CMV in patients without an active viral inflammatory process. Methods: PCR for the detection of HSV, VZV and CMV genomes was done on 33 and 90 intraocular fluids from viral retinal patients and non-viral controls respectively. ELISA was done on 30 and 100 serum samples from viral retinitis patients and normal healthy controls respectively. Results: PCR did not detect HSV, VZV and CMV genomes except one, in which VZV-DNA was detected. ELISA showed prevalence rates of 28%, 83% and 90% for antibodies against HSV, VZV and CMV respectively in the normal population. In the 30 viral retinitis patients, PCR detected HSV-DNA in 2 (6.7%, VZV-DNA in 7 (23.3% and CMV-DNA in 6 (20.0% patients, while ELISA detected antibodies against HSV, VZV and CMV in 13 (43.3%, 24 (80.0% and 23 (76.7% patients respectively. ELISA was of value in indirect diagnosis only in 6 (20.0% as compared to 15 (50.0% of 30 patients by PCR, this difference was statistically significant (McNemar test, P value = 0.005. Conclusion: Serology by ELISA is no longer a useful diagnostic tool to associate HSV, VZV and CMV viruses with viral retinitis.

    There has been limited research on the knowledge of and attitudes about herpes zoster in the Hong Kong population. This study aimed to investigate the knowledge, attitude, and practice of patients aged 50 years or above towards herpes zoster and its vaccination. This was a cross-sectional study in the format of a structured questionnaire interview carried out in Sai Ying Pun Jockey Club General Outpatient Clinic in Hong Kong. Knowledge of herpes zoster and its vaccination was assessed, and patient attitudes to and concerns about the disease were evaluated. Factors that affected a decision about vaccination against herpes zoster were investigated. A total of 408 Hong Kong citizens aged 50 years or above were interviewed. Multiple regression analysis revealed that number of correct responses regarding knowledge about herpes zoster was positively correlated with educational attainment (B=0.313, P=0.026) and history of herpes zoster (B=0.408, P=0.038), and negatively correlated with age (B= -0.042, Pherpes zoster. Misconceptions about herpes zoster were notable in this study. More health education is needed to improve the understanding and heighten awareness of herpes zoster among the general public. Although the majority of participants indicated that herpes zoster would have a significant impact on their health, a relatively smaller proportion was actually worried about getting the disease. Further studies on this topic should be encouraged to gauge the awareness and knowledge of herpes zoster among broader age-groups.

    Herpes zoster (HZ) and postherpetic neuralgia are known to have a profound effect on the patient's quality of life, but the incidence and severity of itch and its relation with pain and quality of life in the long term are still relatively unknown. The aim of this study was to measure the presence and severity of pain and itch and impact on quality of life in patients over 50 years old with HZ. We enrolled 661 patients with HZ in this 12-month observational study. Patient data were collected via a web-based questionnaire. Outcomes were pain, itch, burden of illness, impact on patient's daily life, impact on quality of life, and healthcare costs. At inclusion, 94% of patients reported any pain, 74.3% significant pain, and 26% severe pain. After 3 months, 18.8% of patients suffered from postherpetic neuralgia. At inclusion, 70.8% of patients had any itch, 39.2% significant itch, and 7.3% severe itch. The occurrence of pain increases costs and has a high impact on the quality of life, lowering EQ-5D scores by an average of 18%. In contrast, itch has little effect on the quality of life. Pain and itch are highly prevalent months after HZ. Pain caused by HZ has a large impact on quality of life, burden of illness, impact on daily life, and health care costs for these patients. The impact of itch on quality of life is relatively small. © 2016 World Institute of Pain.

    Tofacitinib is an oral Janus kinase (JAK) inhibitor. Immunomodulatory therapies can increase the risk for herpes zoster (HZ) in patients with psoriasis. To evaluate the relationship between tofacitinib use and HZ risk. We used phases 2 and 3 and long-term extension (LTE) data from the tofacitinib development program in psoriasis to calculate HZ incidence rates (IR; events per 100 patient-years); potential HZ risk factors were evaluated using Cox-proportional hazard models. One hundred thirty (3.6%) patients on tofacitinib (IR 2.55), no patients on placebo, and 2 using etanercept (IR 2.68) developed HZ. Nine patients (7%) were hospitalized, and 8 (6%) had multidermatomal HZ; no encephalitis, visceral involvement, or deaths occurred. In total, 121 (93%) patients on tofacitinib continued or resumed use after HZ. HZ risk factors included Asian descent (hazard ratio [HR] 2.92), using tofacitinib 10 mg twice daily (vs 5 mg twice daily; HR 1.72), prior use of biologics (HR 1.72), and older age (HR 1.30). Generalizability to other psoriasis populations might be limited. The effect of HZ vaccination was not studied. Tofacitinib is associated with increased HZ risk relative to placebo. Asian race, increasing age, higher dose, and prior biologic exposure are associated with heightened risk. Copyright © 2017 American Academy of Dermatology, Inc. Published by Elsevier Inc.

    Full Text Available Background and Design: Herpes zoster (HZ is a rare disease in childhood and encountered especially in immunosuppressed patients. The aim of this study was to determine the clinical features of HZ in children. Materials and methods: Records of 24 children, who had a diagnosis of HZ and were referred to the dermatology and pediatric outpatient clinic during February 2009-February 2011, were evaluated retrospectively. Results: Twenty-four patients, - 14 female (58.3%, 10 male (41.7% -, aged between 4 and 16 years were assessed. The mean age of the patients was 10.6±3.7 years. The most frequent complaint was pruritus (54.2%. Sixteen patients had thoracic involvement, whilst the rest had lumbar (n: 4, trigeminal (n: 3 and sacral (n: 1 involvements, respectively. Eleven children were distressed and 2 children had physical trauma. Ten patients were treated with acyclovir orally, 3 were given valacyclovir orally and the rest had only local treatment. No complications were reported. Conclusion: HZ may be seen in healthy children with no immunosuppresion and the infection in these patients has a favorable course.

    Full Text Available BACKGROUND: Infections of the skin by herpes viruses do not always present themselves in typical fashion. Early diagnosis, however, is crucial for appropriate treatment. Polymerase chain reaction (PCR allows diagnosis and differential diagnosis of herpes virus infections, but the method is not yet available in large parts of the world, where diagnosis is made based on morphology alone. AIM: To refine criteria for the diagnosis of herpes virus infections of the skin by way of correlation of clinical and histopathologic findings with results of PCR studies. METHODS: We studied 75 clinically diagnosed patients of "zoster," "varicella," and "herpes simplex", to correlate clinical and histopathological findings with results of PCR studies on paraffin embedded biopsy specimens. RESULTS: Clinical suspicion of infection by herpes viruses was confirmed by histopathology in 37% of the cases and by PCR studies in 65% of the cases. Zoster was frequently misdiagnosed as infection with herpes simplex viruses (30%. When diagnostic signs of herpes virus infection were encountered histopathologically, PCR confirmed the diagnosis in 94%. By way of correlation with results of PCR studies, initial lesions of herpes virus infections could be identified to have a distinctive histopathological pattern. Herpetic folliculitis appeared to be a rather common finding in zoster, it occurring in 28% of the cases. CONCLUSION: We conclude that correlation of clinical and histopathological features with results of PCR studies on one and the same paraffin embedded specimen permits identification of characteristic morphologic patterns and helps to refine criteria for diagnosis both clinically and histopathologically.

    The effectiveness of zosteric acid, a natural antifoulant from the marine seagrass Zostera marina, in preventing the attachment of quagga mussels, a biofouling bivalve, was investigated. Animals were exposed to water containing zosteric acid ranging from 0 to 1000 ppm, and their attachment to the container glass walls was tracked with time. 500 ppm zosteric acid was not effective at detaching animals that had already attached, but was able to prevent the attachment of most unattached animals for two days. The anti-fouling effect increased with higher concentration. Low concentrations (250 ppm and below) were not effective at preventing attachment; however, 1000 ppm zosteric acid prevented attachment of mussels for the first three days of zosteric acid exposure, and only 20% of the mussels were attached by day 4. In contrast, animals in control (no zosteric acid) solutions began to attach within one day. In conclusion, zosteric acid is an effective natural product deterrent of attachment of a biofouling bivalve.

    Herpes zoster (HZ) is caused by reactivation of the latent varicella-zoster virus (VZV). A severe complication of HZ is VZV vasculopathy which can result in ischemic or hemorrhagic stroke. The aims of our study were to assess the risk of stroke after the onset of HZ and to investigate the roles of stroke subtype, HZ location and the time interval between HZ onset and stroke. A self-controlled case-series study was performed on a cohort of patients with incident stroke recorded in the German Pharmacoepidemiological Research Database (GePaRD), which covers about 20 million persons throughout Germany. We estimated adjusted incidence rate ratios (IRR) by comparing the rate of stroke in risk periods (i.e., periods following HZ) with the rate of stroke in control periods (i.e., periods without HZ) in the same individuals, controlling for both time-invariant and major potentially time-variant confounders. The cohort included 124,462 stroke patients, of whom 6,035 (5%) had at least one HZ diagnosis identified in GePaRD either as main hospital discharge diagnosis or as HZ treated with antivirals. The risk of stroke was about 1.3 times higher in the risk periods 3 months after HZ onset, than in the control periods (IRR: 1.29; 95% confidence interval: 1.16-1.44). An elevated risk of similar magnitude was observed for ischemic and unspecified stroke, but a 1.5-fold higher risk was observed for hemorrhagic stroke. A slightly stronger effect on the risk of stroke was also observed during the 3 months after HZ ophthalmicus (HZO) onset (1.59; 1.10-2.32). The risk was highest 3 and 4 weeks after HZ onset and decreased thereafter. Our study corroborates an increased risk of stroke after HZ, which is highest 3 to 4 weeks after HZ onset. The results suggest that the risk is more pronounced after HZO and is numerically higher for hemorrhagic than for ischemic stroke.

    Enveloped viruses, e.g. influenza- or varicella viruses may cause highly contagious airborne infections. Their spread is difficult to control, also in hospitals. In the case of influenza and varicella immune prophylaxis and chemotherapy/chemoprophylaxis are possible. This is of particular significance, since varicella and zoster are of increasing importance for immunocompromized patients. Diarrhea is caused to a large extent by viruses. Rotavirus infections play an important role in infancy, and are frequently acquired in the hospital. In a study on infectious gastroenteritis of infants in a hospital we were able to show that 30 percent of all rotavirus infections were of nosocomial origin. Admission of a rotavirus-excreting patient (or personnel) may start a long chain of rotavirus infections on pediatric wards. Even careful hygienic measures in the hospital can hardly prevent the spread of enterovirus infections. Such infections may be severe and lethal for newborns, as shown by us in a study on an outbreak of echovirus 11 disease on a maternity ward. We have recently obtained data on the "stickiness" of enteroviruses on human skin. This could explain essential features of the spread of enteroviruses in the population.

    Tofacitinib is an oral, small molecule Janus kinase inhibitor that is being investigated for ulcerative colitis (UC). Tofacitinib is approved for rheumatoid arthritis and psoriatic arthritis, where it has been shown to increase herpes zoster (HZ) risk. We evaluated HZ risk among UC patients using tofacitinib. HZ cases were identified in tofacitinib phase II/III/ongoing, open-label, long-term extension (OLE) UC trials. We calculated HZ incidence rates (IRs) per 100 patient-years of tofacitinib exposure within phase III maintenance (Maintenance Cohort) and phase II/III/OLE (Overall Cohort) studies, stratified by baseline demographics and other factors. HZ risk factors were evaluated in the Overall Cohort using Cox proportional hazard models. Overall, 65 (5.6%) patients developed HZ. Eleven patients had multidermatomal involvement (2 nonadjacent or 3-6 adjacent dermatomes), and 1 developed encephalitis (resolved upon standard treatment). Five (7.7%) events led to treatment discontinuation. HZ IR (95% confidence interval [CI]) in the Overall Cohort was 4.07 (3.14-5.19) over a mean (range) of 509.1 (1-1606) days, with no increased risk observed with increasing tofacitinib exposure. IRs (95% CI) were highest in patients age ≥65 years, 9.55 (4.77-17.08); Asian patients, 6.49 (3.55-10.89); patients with prior tumor necrosis factor inhibitor (TNFi) failure, 5.38 (3.86-7.29); and patients using tofacitinib 10 mg twice daily, 4.25 (3.18-5.56). Multivariate analysis identified older age and prior TNFi failure as independent risk factors. In tofacitinib-treated UC patients, there was an elevated risk of HZ, although complicated HZ was infrequent. Increased HZ rates occurred in patients who were older, Asian, or had prior TNFi failure (NCT00787202, NCT01465763, NCT01458951, NCT01458574, NCT01470612).

    We examined the incidence of herpes zoster in immunocompromised adults (≥18 years) with different severities of immunosuppression and assessed the prevalence of complications and of various kinds of healthcare resource utilisation. German claims data from more than ten million adults were used to calculate annual incidence rates of herpes zoster for the years 2006-2012 and to analyse the prevalence of complications, physician visits, hospitalisations, and antiviral and analgesic treatments using a cohort design. The analyses were stratified by age, sex, and severity of immunosuppression, defined by immunocompromising conditions and drug therapies. The incidence rate per 1000 person-years of herpes zoster was almost twice as high in immunocompromised patients (11.5 (95% confidence interval (CI): 11.4-11.6)) compared to immunocompetent subjects (5.9 (95% CI: 5.8-5.9)). The incidence rate was higher in highly immunocompromised patients (13.4 (95% CI: 13.2-13.6)) than in patients with a low severity of immunosuppression (10.0 (95% CI: 9.8-10.1)). These differences were observed for both sexes and in all age groups. Complications, outpatient physician visits, hospitalisations, and analgesic treatments occurred more frequently in immunocompromised patients as well. Our results show that immunocompromised individuals are affected by the disease in particular and that the burden of herpes zoster is highest in severely immunocompromised patients.

    Biliary atresia (BA) is the most frequent indication for paediatric liver transplantation. We tested the hypothesis of a viral aetiology of this disease by screening liver samples of a large number of BA patients for the common human hepatotropic viruses. Moreover, we correlated our findings to the expression of Mx protein, which has been shown to be significantly up-regulated during viral infections. Seventy-four liver biopsies (taken during Kasai portoenterostomy) were tested by polymerase chain reaction (PCR) for DNA viruses (herpes simplex virus [HSV], Epstein-Barr virus [EBV], varicella zoster virus [VZV], cytomegalovirus [CMV], adenovirus, parvovirus B19 and polyoma BK) and RNA viruses (enteroviruses, rotavirus and reovirus 3). Mx protein expression was assessed by immunohistochemistry. Virus DNA/RNA was found in less than half of the biopsies (8/74 CMV, 1/74 adenovirus; 21/64 reovirus, 1/64 enterovirus). A limited number presented with double infection. Patients that had detectable viral RNA/DNA in their liver biopsies were significantly older than virus-free patients (P = 0.037). The majority (54/59) of the liver biopsies showed expression of Mx proteins in hepatocytes, bile ducts and epithelium. Our data suggest that the known hepatotropic viruses do not play a major role in the aetiology and progression of BA. Their incidence appears to be, rather, a secondary phenomenon. Nonetheless, the inflammatory response in the livers of BA patients mimics that observed during viral infections.

    Patients with rheumatoid arthritis (RA) are at increased risk of herpes zoster, and vaccination is recommended for patients ages 50 years and older, prior to starting treatment with biologic agents or tofacitinib. Tofacitinib is an oral JAK inhibitor for the treatment of RA. We evaluated its effect on the immune response and safety of live zoster vaccine (LZV). In this phase II, 14-week, placebo-controlled trial, patients ages 50 years and older who had active RA and were receiving background methotrexate were given LZV and randomized to receive tofacitinib 5 mg twice daily or placebo 2-3 weeks postvaccination. We measured humoral responses (varicella zoster virus [VZV]-specific IgG level as determined by glycoprotein enzyme-linked immunosorbent assay) and cell-mediated responses (VZV-specific T cell enumeration, as determined by enzyme-linked immunospot assay) at baseline and 2 weeks, 6 weeks, and 14 weeks postvaccination. End points included the geometric mean fold rise (GMFR) in VZV-specific IgG levels (primary end point) and T cells (number of spot-forming cells/10 6 peripheral blood mononuclear cells) at 6 weeks postvaccination. One hundred twelve patients were randomized to receive tofacitinib (n = 55) or placebo (n = 57). Six weeks postvaccination, the GMFR in VZV-specific IgG levels was 2.11 in the tofacitinib group and 1.74 in the placebo group, and the VZV-specific T cell GMFR was similar in the tofacitinib group and the placebo group (1.50 and 1.29, respectively). Serious adverse events occurred in 3 patients in the tofacitinib group (5.5%) and 0 patients (0.0%) in the placebo group. One patient, who lacked preexisting VZV immunity, developed cutaneous vaccine dissemination 2 days after starting tofacitinib (16 days postvaccination). This resolved after tofacitinib was discontinued and the patient received antiviral treatment. Patients who began treatment with tofacitinib 2-3 weeks after receiving LZV had VZV-specific humoral and cell

    Development of attenuated mutants for use as vaccines is in progress for other viruses, including influenza, rotavirus, varicella-zoster, cytomegalovirus, and hepatitis-A virus (HAV). Attenuated viruses may be derived from naturally occurring mutants that infect human or nonhuman hosts. Alternatively, attenuated mutants may be generated by passage of wild-type virus in cell culture. Production of attenuated viruses in cell culture is a laborious and empiric process. Despite previous empiric successes, understanding the molecular basis for attenuation of vaccine viruses could facilitate future development and use of live-virus vaccines. Comparison of the complete nucleotide sequences of wild-type (virulent) and vaccine (attenuated) viruses has been reported for polioviruses and yellow fever virus. Here, the authors compare the nucleotide sequence of wild-type HAV HM-175 with that of a candidate vaccine derivative

    The immunogenicity and safety of an adjuvanted herpes zoster subunit (HZ/su) vaccine when coadministered with a quadrivalent seasonal inactivated influenza vaccine (IIV4) was investigated in a phase 3, open-label, randomized clinical trial in adults aged ≥50 years. Subjects were randomized 1:1 to receive either HZ/su (varicella zoster virus glycoprotein E; AS01B Adjuvant System) and IIV4 at day 0 followed by a second HZ/su dose at month 2 (coadministration group), or IIV4 at month 0 and HZ/su at months 2 and 4 (control group). The primary objectives were the HZ/su vaccine response rate in the coadministration group and the noninferiority of the antibody responses to HZ/su and IIV4 in the coadministration compared with the control group. Safety information was collected throughout the duration of the study. A total of 413 subjects were vaccinated in the coadministration group and 415 in the control group. The HZ/su vaccine response rate in the coadministration group was 95.8% (95% confidence interval, 93.3%-97.6%) and the anti-glycoprotein E GMCControl/Coadmin ratio was 1.08 (.97-1.20). The primary noninferiority objectives were met. No safety concerns were observed. No interference in the immune responses to either vaccine was observed when the vaccines were coadministered, and no safety concerns were identified. NCT01954251. © The Author 2017.

    Abstract Background herpes zoster (HZ) is a common infection with potential complications requiring hospital care, especially for patients with multiple comorbities. However, there is little information on HZ from hospital registries. Methods we searched for hospital-based records of B02 code (ICD-10) between March 2000 and January 2017 at Hospital de Clínicas de Porto Alegre, a tertiary, university hospital in south Brazil. To avoid misclassifications, we considered clinical evaluation for the diagnosis of cutaneous HZ and postherpetic neuralgia (PHN), ophthalmological evaluation for ophthalmic HZ and the combination of clinical, radiologic and cerebrospinal fluid analysis for HZ meningo-encephalitis (ME). We analyzed conditions associated with immune dysregulation, complications, length of hospital stay, and mortality. Chi-square test and Kaplan-Meier estimator were used for statistical analyses. P < 0.05 was considered statistically significant. Results there were 847 records for this period, of which 801 were confirmed according to our criteria and included in the analysis. Most patients were women (n = 448; 60%), with an average of 48.8 years, standard deviation of 22.2. There were more diagnoses in the inpatients group (74.4%), and fewer in the emergency room (22.4%) and outpatient (3.3%). The median length of hospital stay was 7 days (2-10, P25-P75) when HZ was the main reason for admission. Most patients presented cutaneous HZ (n = 743, 92.8%). There were fewer cases of PHN (6.1%), ophthalmic HZ (7.6%) and ME (4.1%). Seventy percent had some kind of immune dysregulation; more frequently AIDS (31%), use of immunosuppressive agents (18.7%) and malignant disease (16.2%). We followed the subjects for a median of 28.2 (2.8-77.5) months. During this period, there were 105 (13.1%) deaths. Five were related to HZ ME. The 30-day overall mortality rate was 1.5%. There was no statistical difference in cumulative survival (graph 1, P = 0.05) or incidence of

    Herpes zoster (HZ) is characterized by debilitating pain and blistering dermatomal rash. The most common complication of HZ is postherpetic neuralgia (PHN), a persistent pain that can substantially affect patients' quality of life. HZ has significant impact on patients' lives with considerable implications for healthcare systems and society. The purpose of this study was to evaluate the healthcare resource utilization (HCRU) and medical costs associated with HZ in Latin America. We conducted a pooled-analysis of three prospective cohort studies of HZ patients ≥50 years of age in Argentina (n=96); Brazil (n=145) and Mexico (n=142). Patients were recruited at different time-points during their HZ episode and were followed for six months. The incidence of PHN was defined as a worst ZBPI pain score of ≥3, persisting or appearing more than 90 days after the onset of rash. Work effectiveness was measured on a 100-point Likert scale where 100 was described as completely effective (able to work like before HZ began) and 0 as not effective at all. Direct costs included costs due to use of antiviral medications and all medical services used to treat HZ. Indirect cost was based on foregone earnings from patients due to work loss and presenteeism, and work loss by family caretakers. One-way sensitivity analysis was performed to assess the impact on total costs. All costs are reported in 2015 USD currency. 383 HZ patients were included and PHN incidence was 38.6%. The most commonly used resources were visits to the doctor's office (79.1% of patients), the emergency room (48.8%) and a specialist (37.9%); hospitalization was reported for 5.7% of patients. The overall direct cost per case was $763.19 USD, indirect cost was $701.40, for a total of $1,464.59 per HZ episode in Latin America. Total cost associated with HZ in patients with PHN was markedly higher compared to patients without PHN ($2,001.13 vs. $867.72, respectively) with indirect costs accounting for the most part

    Objective Patients with rheumatoid arthritis (RA) are at increased risk for herpes zoster (HZ) (i.e., shingles). The aim of this study was to determine whether treatment with tofacitinib increases the risk of HZ in patients with RA. Methods HZ cases were identified as those reported by trial investigators from the databases of the phase II, phase III, and long-term extension (LTE) clinical trials in the Tofacitinib RA Development Program. Crude incidence rates (IRs) of HZ per 100 patient-years (with 95% confidence intervals [95% CIs]) were calculated by exposure group. Logistic regression analyses were performed to evaluate potential risk factors for HZ (e.g., age, prednisone use). Results Among 4,789 participants, 239 were identified as having tofacitinib-associated HZ during the phase II, phase III, and LTE trials, of whom 208 (87%) were female and whose median age was 57 years (range 21–75 years). One HZ case (0.4%) was multidermatomal; none of the cases involved visceral dissemination or death. Twenty-four patients with HZ (10%) permanently discontinued treatment with tofacitinib, and 16 (7%) were either hospitalized or received intravenous antiviral drugs. The crude HZ IR across the development program was 4.4 per 100 patient-years (95% CI 3.8–4.9), but the IR was substantially higher within Asia (7.7 per 100 patient-years, 95% CI 6.4–9.3). Older age was associated with HZ (odds ratio 1.9, 95% CI 1.5–2.6), and IRs for HZ were similar between patients receiving 5 mg tofacitinib twice daily (4.4 per 100 patient-years, 95% CI 3.2–6.0) and those receiving 10 mg twice daily (4.2 per 100 patient-years, 95% CI 3.1–5.8). In the phase III trials among placebo recipients, the incidence of HZ was 1.5 per 100 patient-years (95% CI 0.5–4.6). Conclusion In the Tofacitinib RA Development Program, increased rates of HZ were observed in patients treated with tofacitinib compared with those receiving placebo, particularly among patients within Asia. Complicated HZ

    The objective of the study was to analyze the descriptive epidemiology and costs of herpes zoster (HZ) and postherpetic neuralgia (PHN) in people aged ≥50 years in Catalonia (Spain). The incidence of HZ in Catalonia was estimated by extrapolating the incidence data from Navarre (Spain) to the population of Catalonia. The incidence of PHN was estimated according to the proportion of cases of HZ in the case series of the Hospital del Sagrado Corazón de Barcelona that evolved to PHN. Drug costs were obtained directly from the prescriptions included in the medical record (according to official prices published by the General Council of the College of Pharmacists). The cost of care was obtained by applying the tariffs of the Catalan Health Institute to the number of outpatient visits and the number and duration of hospital admissions. The estimated annual incidence of HZ was 31 763, of which 21 532 (67.79%) were in patients aged ≥50 years. The respective figures for PHN were 3194 and 3085 (96.59) per annum, respectively. The mean cost per patient was markedly higher in cases of PHN (916.66 euros per patient) than in cases of HZ alone (301.52 euros per patient). The cost increased with age in both groups of patients. The estimated total annual cost of HZ and its complications in Catalonia was € 9.31 million, of which 6.54 corresponded to HZ and 2.77 to PHN. This is the first Spanish study of the disease burden of HZ in which epidemiological data and costs were collected directly from medical records. The estimated incidence of HZ is probably similar to the real incidence. In contrast, the incidence of PHN may be an underestimate, as around 25% of patients in Catalonia attend private clinics financed by insurance companies. It is also probable that the costs may be an underestimate as the costs derived from the prodromal phase were not included. In Catalonia, HZ and PHN cause an important disease burden (21 532 cases of HZ and 3085 de PHN with an annual cost

    Spaceflight is a uniquely stressful environment with astronauts experiencing a variety of stressors including: isolation and confinement, psychosocial, noise, sleep deprivation, anxiety, variable gravitational forces, and increased radiation. These stressors are manifested through the HPA and SAM axes resulting in increased stress hormones. Diminished T-lymphocyte functions lead to reactivation of latent herpesviruses in astronauts during spaceflight. Herpes simplex virus reactivated with symptoms during spaceflight whereas Epstein-Barr virus (EBV), cytomegalovirus (CMV), and varicella zoster virus (VZV) reactivate and are shed without symptoms. EBV and VZV are shed in saliva and CMV in the urine. The levels of EBV shed in astronauts increased 10-fold during the flight; CMV and VZV are not typically shed in low stressed individuals, but both were shed in astronauts during spaceflight. All herpes viruses were detected by polymerase chain reaction (PCR) assay. Culturing revealed that VZV shed in saliva was infectious virus. The PCR technology was extended to test saliva of 54 shingles patients. All shingles patients shed VZV in their saliva, and the levels followed the course of the disease. Viremia was also found to be common during shingles. The technology may be used before zoster lesions appear allowing for prevention of disease. The technology may be used for rapid detection of VZV in doctors offices. These studies demonstrated the value of applying technologies designed for astronauts to people on Earth.

    To study the various clinical presentations of herpes zoster and to find out the proportion of HIV positivity in these patients. A time bound study was conducted from November 2004 to October 2005. All clinically diagnosed cases of herpes zoster were tested for HIV infection with ELISA and confirmed by Tridot and Coomb AID. Total numbers of 90 zoster cases were recorded. Mean duration of pre herpetic neuralgia was 2.134 (standard deviation=1.424, F=8.951, Psacral (6.66%) nerves. A substantial proportion, 34 (37.77%) out of 90 cases, were found to be HIV positive. Of these, 64.7 percent of the HIV seropositive herpes zoster patients belonged to the age group of 21-40 years. Out of 39 who had a risk of exposure to STDs and whose ages were less than 50 years, 31 (79.48%) tested positive for HIV infection. The occurrence of zoster in the young age group in patients who report a history of risk factors for HIV, may need testing. Herpes zoster serves as a clinical indicator of HIV seropositivity and one of the earliest manifestations.

    Objective: To determine the dose-response relationship of ropivacaine for epidural block in early herpes zoster by CT guided. Methods: From January 2015 to February 2017, according to the principle of completely random digital table, 80 patients with early herpes zoster who were prepared for epidural block were divided into 4 groups(each group 20 patients): in group A the concentration of ropivacaine was 0.08%, in group B was 0.10%, in group C was 0.12% and in group D was 0.14%.Under CT guidance, epidural puncture was performed in the relevant section, mixing liquid 5.0 ml (with 10% iodohydrin)were injected into epidural gap.CT scan showed that the mixing liquid covered the relevant spinal nerve segmental.The numeric rating scale(NRS) values before treatment and at 30 minutes, the incidence of adverse reactions were recorded, and the treatment were evaluated. The response to ropivacaine for epidural block in early herpes zoster was defined as positive when the NRS values was less than or equal to one.The ED(50), ED(95) and 95% confidence interval ( CI ) of ropivacaine for epidural block in early herpes zoster guided by CT were calculated by probit analysis. Results: The NRS values before treatment were 5.00(4.00, 6.00), 5.00(4.25, 6.00), 5.50(5.00, 6.00) and 5.00(4.00, 6.00), the difference was no significant( Z =2.576, P =0.462). The NRS values at 30 minutes decreased and the effective rate of the treatment increased(χ(2)=8.371, P =0.004), following ropivacaine dose gradient increasing, they were 1.50(1.00, 2.00), 1.00(1.00, 2.00), 0.50(0.00, 1.00) and 0.00(0.00, 1.00), the difference was statistically significant ( Z =17.421, P =0.001). There was one case in group C and four cases in group D were hypoesthesia, others were no significant adverse reactions occurred. The ED(50) and ED(95) (95% CI ) of ropivacaine for epidural block in early herpes zoster guided by CT were 0.078%(0.015%-0.095%)and 0.157%(0.133%-0.271%), respectively. Conclusion: Ropivacaine for

    Herpes zoster ophthalmicus, in which orbital symptoms and signs appear before the onset of a skin rash, is very rare. We experienced such a case and therefore report on it via magnetic resonance imaging. A 48-year-old man with pain and swelling of left eye and headache presented 2 days before onset of a zoster skin rash. On orbit-al MRI, edematous thickening of the left lateral rectus muscle with high signal intensity was revealed. After contrast injection, the lateral rectus muscle demonstrated heterogenous enhancement. Also, diffuse contrast enhancement was noted at left preseptal space, lacrimal gland and periorbital soft tissue. The man was treated with antiviral agents and prednisolone. Two weeks later, he recovered from the skin manifestations and most of the orbital manifestations except for the diplopia and restricted lateral movement.

    Full Text Available Three hundred patients of different ages were sequentially assigned three therapy groups (100 in each group viz. phenytoin, steroid (prednisolone and carbamazepine. Effect of these drugs on herpes zoster neuralgia and in prevention of post herpetic neuralgia was studied. Phenytoin was found to be superior to both steroid and carbamazepine in relieving the pain of herpes zoster and in reducing the incidence of post herpetic neuralgia. Only 16.1% of the patients in phenytoin treated group developed post herpetic neuralgia lasting for 2-4 weeks while 22.7% and 29.6% of the steroid and carbamazepine treated patients respectively developed post herpetic neuralgia and that too lasting for longer duration. No patient under 40 years developed post herpetic neuralgia.

    Wet cupping is a traditional Chinese medicine therapy commonly used in treating herpes zoster in China, and clinical studies have shown that wet cupping may have beneficial effect on herpes zoster compared with Western medication. We included randomized controlled trials (RCTs) on wet cupping for herpes zoster. We searched PubMed, the Cochrane Library (Issue 3, 2008), China Network Knowledge Infrastructure (CNKI), Chinese Scientific Journals Fulltext Database VIP, and Wan Fang Database. All searches ended in February 2009. Two authors extracted data and assessed the trials' quality independently. RevMan 5.0.18 software (The Cochrane Collaboration, The Nordic Cochrane Centre, Copenhagen, Denmark) was used for data analysis with effect estimate presented as relative risk (RR) and mean difference (MD) with a 95% confidence interval (CI). Eight RCTs involving 651 patients were included, and the methodological quality of trials was generally fair in terms of randomization, blinding, and intention-to-treat analysis. Meta-analyses showed wet cupping was superior to medication in the number of cured patients (RR 2.49, 95% CI 1.91 to 3.24, P cupping plus medication was significantly better than medication alone on number of cured patients (RR 1.93, 95% CI 1.23 to 3.04, P = .005) but demonstrated no difference in symptom improvement (RR 1.00, 95% CI 0.92 to 1.08, P = .98). There were no serious adverse effects related to wet cupping therapy in the included trials. Wet cupping appears to be effective in the treatment of herpes zoster.

    Summary Objectives To describe the characteristics of HIV-infected patients experiencing herpes zoster after antiretroviral therapy (ART) initiation and to describe the incidence and predictors of a herpes zoster diagnosis. Methods Adult patients initiating ART from April 2004 to September 2011 at the Themba Lethu Clinic in Johannesburg, South Africa were included. Patients were followed from ART initiation until the date of first herpes zoster diagnosis, or death, transfer, loss to follow-up, or dataset closure. Herpes zoster is described using incidence rates (IR) and predictors of herpes zoster are presented as subdistribution hazard ratios (sHR) and 95% confidence intervals (95% CI). Results Fifteen thousand and twenty-five patients were included; 62% were female, the median age was 36.6 years, and the median baseline CD4 count was 98 cells/mm3. Three hundred and forty patients (2.3%) experienced herpes zoster in a median of 26.1 weeks after ART initiation. Most (71.5%) occurred within 1 year of initiation, for a 1-year IR of 18.1/1000 person-years. In an adjusted model, patients with low CD4 counts (herpes zoster (sHR: 1.53, 95% CI: 0.97–2.28) were at increased risk of incident herpes zoster. Conclusions While only 2% of patients were diagnosed with herpes zoster in this cohort, patients with low CD4 counts and those with prior episodes of herpes zoster were at higher risk for a herpes zoster diagnosis.

    The objectives of this study were to characterize the burden of herpes zoster, as well as the longitudinal and incremental changes of healthcare service utilization among individuals with herpes zoster and postherpetic neuralgia (PHN) compared to those without. Using the National Health Insurance Research Database (NHIRD), we established a herpes zoster cohort of people diagnosed with herpes zoster between 2004 and 2008 as study cases. Another subset of the NHIRD, which was randomly selected from all elderly beneficiaries between 2004 and 2008 served as a non-herpes-zoster elderly control pool. Each case was then assigned one matched control according to age, gender, index date and propensity score. PHN cases were defined as those with persisting pain for more than 90 days after the onset of herpes zoster. Between 2004 and 2008, about 0.6 million patients were newly diagnosed with herpes zoster. The incidence increased with age, and most cases were identified during the summer period. Herpes zoster cases were found to have higher consumption of all types of healthcare services in the first year after the index date. Such increases were particularly obvious for patients with PHN, who showed incremental increases on average of 16.3 outpatient visits, 0.4 emergency room visits and 0.24 inpatient admissions per year. The incidence of herpes zoster increased with age and changed according to the seasons. Patients with herpes zoster were associated with higher healthcare utilization and this increase in healthcare utilization was most obvious for herpes zoster patients with PHN.

    Full Text Available Herpes zoster infection and stroke are highly prevalent in the general population; however, reports have presented inconsistent findings regarding the relationship between herpes zoster infection and stroke. In this meta-analysis, we aimed to clarify this association.The PubMed and Embase databases were searched for studies published from their inception to January 2016. Two investigators independently extracted the data. The pooled relative risk (RR was calculated using a random effects model.A total of 8 studies met the inclusion criteria. During the first 1 month after herpes zoster infection, the pooled RRs for ischemic stroke and hemorrhagic stroke were 1.55 (95% CI, 1.46-1.65 and 1.70 (95% CI, 0.73-3.96, respectively, and within 3 months after infection, the corresponding RRs were 1.17 (95% CI, 1.12-1.23 and 2.05 (95% CI, 1.17-3.60, respectively. At 1 year and more than 1 year after herpes zoster infection, a significant relationship was not observed between herpes zoster infection and the incidence of ischemic and hemorrhagic stroke. Publication bias was not observed.The accumulated evidence generated from this systematic review indicates that an increased risk for ischemic stroke occurred in the short term after herpes zoster infection, whereas a significant relationship was not observed in the long term after infection. With respect to hemorrhagic stroke, the association was not significant. With respect to hemorrhagic stroke, the association between was not significant except within 3 months after a herpes zoster infection.

    A 66-year-old man presented with headache and ophthalmalgia. Diplopia developed, and he was hospitalized. The left eye had abducent paralysis and proptosis. We diagnosed him with Tolosa-Hunt syndrome and administered methylprednisolone at 1 g/day for 3 days. However, the patient did not respond to treatment. No abnormality was found on his MRI or cerebrospinal fluid examination. Tests showed his serum immunoglobulin G4 and antineutrophil cytoplasmic antibody titers were within normal limits. He also had untreated diabetes mellitus (HbA1c 9.2). One week after first presenting with symptoms, herpes zoster appeared on the patient's dorsum nasi, followed by keratitis and a corneal ulcer. Herpes zoster ophthalmicus with ophthalmoplegia was diagnosed. We began treatment with acyclovir (15 mg/kg) and prednisolone (1 mg/kg, decreased gradually). Ophthalmalgia and the eruption improved immediately. The eye movement disorder improved gradually over several months. It is rare that diplopia appears prior to cingulate eruption of herpes zoster ophthalmicus. We speculated that onset of the eruption was inhibited by strong steroid therapy and untreated diabetes mellitus.

    A new human herpes virus has been isolated from CD4 + T cells purified from peripheral blood mononuclear cells of a healthy individual (RK), following incubation of the cells under conditions promoting T-cell activation. The virus could not be recovered from nonactivated cells. Cultures of lymphocytes infected with the RK virus exhibited a cytopathic effect, and electron microscopic analyses revealed a characteristic herpes virus structure. RK virus DNA did not hybridize with large probes derived from herpes simplex virus, Epstein-Barr virus, varicella-zoster virus, and human cytomegalovirus. The genetic relatedness of the RK virus to the recently identified T-lymphotropic human herpes virus 6 (HHV-6) was investigated by restriction enzyme analyses using 21 different enzymes and by blot hydridization analyses using 11 probes derived from two strains of HHV-6 (Z29 and U1102). Whereas the two HHV-6 strains exhibited only limited restriction enzyme polymorphism, cleavage of the RK virus DNA yielded distinct patterns. Of the 11 HHV-6 DNA probes tested, only 6 cross-hybridized with DNA fragments derived from the RK virus. Taken together, the maximal homology amounted to 31 kilobases of the 75 kilobases tested. The authors conclude that the RK virus is distinct from previously characterized human herpesviruses. The authors propose to designate it as the prototype of a new herpes virus, the seventh human herpes virus identified to date

    HZ/Su, branded as 'Shingrix', is one of the newest vaccines to be submitted for multi-national regulatory approval. It is targeted to prevent shingles, a global concern with aging populations. A live attenuated vaccine for shingles has been available for over a decade, however it is contraindicated in specific subgroups of people, and there are added concerns regarding long-term immunogenicity. HZ/Su is the first subunit vaccine developed to protect against shingles. This paper provides a critical appraisal of current evidence regarding HZ/Su.

    There are eight herpes viruses that infect humans, causing a wide range of diseases resulting in considerable morbidity and associated costs. Varicella zoster virus (VZV) is a human herpes virus that causes chickenpox in children and shingles in adults. Approximately 1,000,000 new cases of shingles occur each year; post-herpetic neuralgia (PHN) follows shingles in 100,000 to 200,000 people annually. PHN is characterized by debilitating, nearly unbearable pain for weeks, months, and even years. The onset of shingles is characterized by pain, followed by the zoster rash, leading to blisters and severe pain. The problem is that in the early stages, shingles can be difficult to diagnose; chickenpox in adults can be equally difficult to diagnose. As a result, both diseases can be misdiagnosed (false positive/negative). A molecular assay has been adapted for use in diagnosing VZV diseases. The polymerase chain reaction (PCR) assay is a non-invasive, rapid, sensitive, and highly specific method for VZV DNA detection. It provides unequivocal results and can effectively end misdiagnoses. This is an approximately two-hour assay that allows unequivocal diagnosis and rapid antiviral drug intervention. It has been demonstrated that rapid intervention can prevent full development of the disease, resulting in reduced likelihood of PHN. The technology was extended to shingles patients and demonstrated that VZV is shed in saliva and blood of all shingles patients. The amount of VZV in saliva parallels the medical outcome.

    A 15-year-old healthy boy developed acute, rapidly progressing visual loss in left eye following herpes zoster dermatitis, with a combined central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO), along with optic perineuritis. Laboratory tests were negative. Despite an empirical, intensive antiviral treatment with systemic corticosteroids, and vision could not be restored in the affected eye. Herpes zoster dermatitis, in an immunocompetent individual, may be associated with a combined CRAO and CRVO along with optic perineuritis, leading to profound visual loss.

    Protection against herpes zoster (HZ) induced by the live attenuated zoster vaccine Zostavax (ZVL) wanes within 3-7 years. Revaccination may renew protection. We assessed whether (re)vaccination with the adjuvanted HZ subunit vaccine candidate (HZ/su) induced comparable immune responses in previous ZVL recipients and ZVL-naive individuals (HZ-NonVac). In an open-label, multicenter study, adults ≥65 years of age, vaccinated with ZVL ≥5 years previously (HZ-PreVac), were matched to ZVL-naive adults (HZ-NonVac). Participants received 2 doses of HZ/su 2 months apart. The primary objective of noninferiority of the humoral immune response 1 month post-dose 2 was considered demonstrated if the upper limit of the 95% confidence interval (CI) of the adjusted anti-glycoprotein E geometric mean concentration (GMC) ratio of HZ-NonVac over HZ-PreVac was <1.5. HZ/su cellular immunogenicity, reactogenicity, and safety were also assessed. In 430 participants, humoral immune response to HZ/su was noninferior in HZ-PreVac compared with HZ-NonVac (adjusted GMC ratio, 1.04 [95% CI, .92-1.17]). Cellular immunogenicity, reactogenicity, and safety appeared to be comparable between groups. HZ/su was well-tolerated, with no safety concerns raised within 1 month post-dose 2. HZ/su induces a strong immune response irrespective of prior vaccination with ZVL, and may be an attractive option to revaccinate prior ZVL recipients. NCT02581410. © The Author 2017.

    Although the efficacy of modern antiviral agents for the treatment of herpes zoster is unquestioned, their ability to affect the associated pain remains controversial. We have therefore evaluated the inpatient hospital records of 550 patients with herpes zoster with regard to pain-related clinical aspects and therapeutic responsiveness. Intensity of pain was quantified by calculating a daily pain equivalence index (PEI) on the basis of different classes of pain medication and the number of tablets used in each category. The mean age of patients was 66.7 years, cranial segments were predominantly involved (55%), 64% of patients suffered from associated diseases and 77% experienced herpes-related pain. The PEI was 0.90 in the entire patient population, with significantly higher values in women and in patients with 3 or more associated diseases. It was lower in sacral and cranial nerve involvement, and it decreased rapidly in patients prior to discharge from hospital. Although there were significant differences in hospital stay between patients who received aciclovir and those who did not (mean 20.3 vs. 23.8 days), and for high- versus low-dose oral or intravenous administration, no significant differences were noted between the two groups for initial PEI values and during the course of observation, irrespective of the route of administration or the dose of aciclovir and the individual patient's PEI value. The groups were otherwise closely similar with regard to basic demographic and clinical data. 23.3% predominantly aged female patients with more associated diseases than the total patient population had a persistently elevated PEI and stayed in hospital beyond 21 days (mean 35.1 days), representing patients who went on to postherpetic neuralgia. These data further delineate clinical aspects of acute herpes zoster neuralgia, underline the unsolved therapeutic problems associated with this condition despite otherwise effective antiviral treatment, and characterise a

    A 62-year-old-man treated for nephrotic syndrome with steroid developed acute pain of herpes zoster after immobility of the shoulder. Steroids might have suppressed the first symptoms of pain. But immobility probably appeared as VZV infection developing to spinal ventral root. Suprascapular nerve block was effective for severe pain of the right arm. Sympathetic nerve contained in suprascapular nerve might have been blocked. Sympathetically maintained pain may occur when primary afferent neurons are excited by inflammation due to VZV infection. Pain was abolished 17 weeks after the onset of rash using blocks three times and amitriptyrin and valproic acid. Immobility was resolved seven months after the onset of rash.

    The aim of this study was to investigate the etiological role of human papilloma virus (HPV), herpes simplex virus (HSV), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), cytomegalovirus (CMV), and human herpes virus-6 (HHV-6) and -7 (HHV-7) in the occurrence of nasal polyposis. Nasal polyp samples from 30 patients with nasal polyposis and normal nasal mucosa from 10 patients without nasal polyps were obtained. DNA was extracted from tissues. Real-time polymerase chain reaction was performed for all runs. No HSV-1, HSV-2, or VZV was detected in the samples. Among the patient samples, EBV and HHV-7 DNA were detected in 18 (60%), HHV-6 was detected in 20 (66.7%), and HPV was detected in 4 (13.3%) samples. Among the controls, CMV DNA was positive in one (10%). EBV was positive in 5 (50%), HHV-6 and HHV-7 were positive in 7 (70%), and HPV was positive in 2 (20%) samples. No significant difference was found among the groups with any test in terms of positivity. The association of Herpesviridae and HPV with the pathogenesis of nasal polyps was investigated in this study and no relationship was found. Thus, these viruses do not play a significant role in the formation of nasal polyps.

  7. Natural and adoptive T-cell immunity against herpes family viruses after allogeneic hematopoietic stem cell transplantation.

    Reactivated infections with herpes family-related cytomegalovirus, Epstein-Barr virus and varicella zoster virus are serious and sometimes life-threatening complications for patients undergoing allogeneic hematopoietic stem cell transplantation. The pathogenesis of these infections critically involves the slow and inefficient recovery of antiviral T-cell immunity after transplantation. Although efficient drugs to decrease viral load during this vulnerable period have been developed, long-term control of herpes viruses and protection from associated diseases require the sufficient reconstitution of virus-specific memory T cells. To heal the deficiency by immunotherapeutic means, numerous research groups have developed antiviral vaccines and strategies based on the adoptive transfer of virus-specific T cells. This article summarizes the substantial progress made in this field during the past two decades and gives future perspectives about challenges that need to be addressed before antigen-specific immunotherapy against herpes family viruses can be implemented in general clinical practice.

    Full Text Available BackgroundPrevention of infectious diseases is of high priority in the rapidly aging population. Unfortunately, vaccine responses in the elderly are frequently diminished. Timely vaccination of middle-aged adults might improve the immune responses to vaccines, although knowledge on pathogen-specific immune responses and factors affecting these responses, in middle-aged adults is currently limited. We thus investigated the immune responses after vaccination with Zostavax consisting of live-attenuated varicella zoster virus (VZV.MethodsBlood samples were taken pre-, 14 days, 28 days, and 1 year after a primary VZV vaccination (Zostavax at middle age (N = 53, 50–65 years of age. VZV-specific IFNγ-producing cells were measured by ELISpot, activated T-cells by flow cytometry, antibody levels and cytokine responses by fluorescent bead-based multiplex immunoassays, and whole blood cellular kinetics by TruCOUNT analysis.ResultsRobust short-term enhancement of the VZV-specific IFNγ-producing cell numbers was observed post-vaccination in the middle-aged adults. Remarkably, long-term enhancement of VZV-specific IFNγ-producing cell numbers was induced only in participants with low numbers of VZV-specific pre-vaccination IFNγ-producing cells, who were significantly older. These participants also showed enhancement of VZV-specific activated CD4 T-cells, contrary to “exhausted” VZV-specific CD8 T-cells in participants with high numbers of VZV-specific pre-vaccination IFNγ-producing cells. Finally, a high CD4/CD8 T-cell ratio was associated with low numbers of pre-vaccination VZV-specific IFNγ-producing cells.ConclusionThese results suggest that adults in their early sixties, who showed a high CD4/CD8 T-cell ratio and low numbers of VZV-specific IFNγ-producing cells, benefit from VZV vaccination. This provides important knowledge on factors affecting VZV-specific immune responses in middle-aged adults as well as for strategies to

    Neuroimmune activation has been proposed as a source of new targets for therapeutic intervention in neuropathic pain. Vimang® is an aqueous extract from Mangifera indica L. (common mango) that is traditionally used in Cuba for its antioxidant, anti-inflammatory, analgesic, and immunomodulatory properties. In the present case report, we determine its potential effects in patients with zoster-associated pain. 12 patients with zoster-associated pain (6 with subacute herpetic neuralgia and 6 with post-herpetic neuralgia) received a daily dose of 1,800 mg of extract (2 coated 300 mg tablets, 3 times daily before meals) together with low doses of amitriptyline (10-25 mg/day) for 120 days. In addition to the tablets, patients used Vimang® cream 1.2% as a topical agent. The average daily pain score using the Likert scale, area and rate of dynamic allodynia, rate of thermal allodynia, and frequency of burning spontaneous pain were evaluated. Pain scores and sensory abnormalities decreased significantly (p Vimang® could be beneficial in the treatment of neuropathic pain. However, a controlled clinical trial is necessary to confirm this hypothesis. Copyright © 2011 S. Karger AG, Basel.

    Herpes zoster (HZ), also known as shingles, is a painful and commonly occurring condition in the United States. In spite of a universally recommended vaccine for use in immunocompetent adults aged 60 years and older, HZ continues to impact the American public, and a better understanding of its current incidence is needed. The objective of the current study is to estimate the overall and age- and gender-specific incidence rates (IRs) of HZ among an immunocompetent US population in 2011 following availability of a vaccine. Claims data from the Truven Health MarketScan® Research databases between 01/01/2011 and 12/31/2011 were extracted. Immunocompetent adult patients, enrolled as of January 1, 2011 were analyzed. The denominator was defined as eligible subjects who were immunocompetent, had no evidence of zoster vaccination, and no diagnosis of HZ (International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code 053.xx) in the 90 days prior to January 1, 2011. Subjects contributed person-days to the denominator until the occurrence of one of the following events: end of continuous enrollment in the database, a claim for zoster vaccination, diagnosis of HZ or end of the observation period (December 31, 2011). The numerator was defined as enrollees within the denominator file exhibiting evidence of HZ. Annual IRs were calculated for the entire population in the database as well as by gender and age group; standardized IRs were also produced using the 2010 US Census data. The overall annual IR of HZ across all ages was 4.47 per 1000 person-years (95% confidence interval [CI]: 4.44-4.50) which monotonically increased with age from 0.86 (95% CI: 0.84-0.88) for those aged ≤ 19 to 12.78 (95% CI: 12.49-13.07) for patients ≥ 80 years. The IR was 8.46 (95% CI: 8.39-8.52) among adults ≥ 50 years and 10.46 (95% CI: 10.35-10.56) among those aged ≥ 60 years. Women compared to men had higher HZ incidence (5.25, 95% CI: 5.21-5.29 vs. 3.66, 95

    To evaluate the MRI findings of acute facial nerve paralysis in Bell's palsy and herpes zoster opticus, and to correlate these with the clinical findings. We retrowspectively reviewed the MRI findings in six cases of BEll's palsy(BP) and two of herpes zoster oticus(HZO), and compared them with the findings for 30 normal facial nerves. This nerve was considered abnormal when its signal intensity was greater than that of brain parenchyma or the contralateral normal side on Gd-enhanced T1-weighted axial and coronal MR images. We analysed the location and degree of contrast enhancement, interval change, and clinical progression in correlation with House-Brackmann(HB) grade and electroneuronography (ENoG) findings. Fifteen of 30 normal facial nerves(50%) seen on Gd-enhanced MRI were mildly enhanced in the geniculate ganglion, the proximal tympanic, and the proximal mastoid segment of the facial nerve. No enhancement of the internal auditory canal(IAC) or labyrinthine segment of the facial nerve was noted, however. In BP and HZO, Gd-enhanced MR images revealed fair to marked enhancement for more than two segments from the internal auditory canal to the mastoid segment of the facial nerve. During follow-up MRI, enhancement of the facial nerve varied in location and signal intensity, though gradually decreased in intensity approximately eight weeks after the onset of facial nerve palsy. No correlation between clinical HB grade, ENoG, and follow up MRI findings was noted. Except in the internal auditory canal and labyrinthine segment, normal facial nevemay show mild and relatively symmetrical enhancement. In BP and HZO, the facial nerve showed diffuse enhancement from the IAC to the mastoid segment.=20.

    The aim of this study was to compare the public health impact of introducing 2 Herpes Zoster (HZ) vaccines, Zoster Vaccine Live (ZVL) versus a non-live adjuvanted subunit candidate vaccine (HZ/su), in the German population aged 50+ years split into 3 age cohorts, i.e. 50-59, 60-69 and 70+ years, respectively. A multi-cohort static Markov model was developed following age cohorts over their lifetime. Demographic data were obtained from the German federal statistical office. HZ incidence and the proportion of HZ individuals developing post-herpetic neuralgia (PHN) were derived from German specific sources. Age-specific vaccine efficacy and waning rates were based on published clinical trial data. Vaccine coverage for both vaccines was assumed to be 40%, with compliance of the second dose of the HZ/su vaccine of 70%. Sensitivity analyses were performed to assess the robustness of the results. It was estimated that, over the remaining lifetime since vaccination, the HZ/su vaccine would reduce the number of HZ cases by 725,233, 533,162 and 486,794 in the 3 age cohorts, respectively, compared with 198,477, 196,000 and 104,640, using ZVL. The number needed to vaccinate (NNV) to prevent one HZ case ranged from 8 to 11 using the HZ/su vaccine compared with 20 to 50 using ZVL. Corresponding NNV to prevent one PHN case ranged from 39 to 53 using the HZ/su vaccine compared with 94 to 198 using ZVL. Due to the higher, sustained vaccine efficacy, the candidate HZ/su vaccine demonstrated superior public health impact compared with ZVL.

    Full Text Available O herpes zoster (HZ resulta da reativação do vírus varicela-zoster (VVZ. A incidência aumenta com a idade, sendo raro em crianças saudáveis. Descrevemos um caso de HZ oftálmico numa menina de 29 meses, previamente saudável. Apresentava febre e erupção cutânea vesicular dolorosa no território oftálmico do nervo trigémio. Sem história de varicela ou vacinação anti-varicela prévias. Teve contacto intrafamiliar com varicela aos dois meses de idade. A pesquisa do vírus nas vesículas por polimerase chain reaction foi positiva. Os títulos de IgG e IgM anti-vírus varicela-zoster foram inicialmente negativos, tendo ocorrido seroconversão oito semanas depois. Medicada com aciclovir endovenoso, recuperou sem sequelas. O HZ pode ocorrer em crianças previamente saudáveis, sem evidência de varicela anterior e com serologia para VVZ negativa. Tal pode ser explicado pela imaturidade do sistema imunológico, assim como pela transferência transplacentária de anticorpos maternos, aquando da infeção primária precoce.

    Despite the successful use of tyrosine kinase inhibitors (TKIs) in cancer patients, their effect on herpes zoster development has not been studied. The aim of this study was to evaluate and compare the effects of epidermal growth factor receptor (EGFR) TKI and cytotoxic chemotherapy on the risk of herpes zoster development in non-small cell lung cancer (NSCLC) patients. We conducted a medical review of all eligible NSCLC patients in Seoul National University hospital between 2002 and 2015. We classified patients based on whether they previously underwent EGFR TKI therapy into either the TKI group or the cytotoxic group. We compared the incidence rates of herpes zoster during TKI therapy and cytotoxic chemotherapy. Additionally, the longitudinal risk of herpes zoster from TKIs was analyzed using the incidence rate ratio (IRR) of the TKI group to the cytotoxic group and the log-rank test of the Kaplan-Meier method. Of the 2,981 NSCLC patients, 54 patients (1.54%) developed herpes zoster. In the TKI group (2,002 patients), the IRR of herpes zoster during TKI therapy compared to that during cytotoxic chemotherapy was 1.05 (95% confidence interval [CI], 0.53 to 2.09). The IRR of the TKI group compared to the cytotoxic group was 1.33 (95% CI, 0.64 to 2.76). The Kaplan-Meier cumulative risk of both groups was not significantly different. Our results show that the incidence rate of herpes zoster in the TKI group was not statistically different from the incidence in the cytotoxic group during and after chemotherapy in NSCLC patients.

    The recent authorization and commercialization in the USA of a "Zoster vaccine" with high antigenic titer opens interesting perspectives of prevention against herpes zoster (HZ). This disease is characterized by a vesicular rash with dermatomeric extension and by moderate to severe pain. Many patients present with post-herpetic neuralgia. In Italy, complete and recent epidemiological data are not available. We evaluated the epidemiological features of patients presenting with HZ observed at the Ferrara University Dermatology unit from 2000 to 2008. The following data were collected: gender, age, residence, date and place of consultation, localization, and therapy. The place of consultation was often (43%) not specified; in the remaining 57% of cases, patients were sent from general and ophthalmology emergency rooms. The most frequent localizations were: 32% ophthalmic; 16.5% thoracic; 16% facial. Most patients were treated with oral antiviral drugs for seven days. According to localization and severity, topical or oral antibiotics, analgesics, neurotrophic drugs were prescribed. This data, although not representative of all cases in the province of Ferrara, confirmed the epidemiological impact of Zoster, which brings a number of patients to use the hospital and specialized structures for diagnosis and cure.

    2010-06-01

    Full Text Available Immunodeficient patients are at risk of developing extended or atypical herpes simplex virus infections, which can be easily misdiagnosed. We present the case of a 79-year-old, treatment-induced (oral corticosteroid, immunocompromised female with an extensive atypical herpes simplex virus infection. This patient presented with multiple erosions and vesicles on the trunk with a subacute onset. The clinical differential diagnosis was herpes simplex infection, herpes zoster infection, pemphigus vulgaris or bullous pemphigoid. Due to the atypical clinical presentation and negative Tzanck test, suspicion of viral infection was low. High-dose steroid treatment was initiated. Subsequent histopathology, however, showed a herpes simplex virus infection. After discontinuing steroid treatment and initiating antiviral treatment, the patient recovered within a week. Emphasis must be placed on the importance of clinical awareness of extended and clinically atypical herpes simplex infections in immunocompromised patients. A negative Tzanck test does not rule out the possibility of a herpes infection.

    Latent virus reactivation was measured in 17 astronauts (16 male and 1 female) before, during, and after short-duration Space Shuttle missions. Blood, urine, and saliva samples were collected 2-4 months before launch, 10 days before launch (L-10), 2-3 hours after landing (R+0), 3 days after landing (R+14), and 120 days after landing (R+120). Epstein-Barr virus (EBV) DNA was measured in these samples by quantitative polymerase chain reaction. Varicella-zoster virus (VZV) DNA was measured in the 381 saliva samples and cytomegalovirus (CMV) DNA in the 66 urine samples collected from these subjects. Fourteen astronauts shed EBV DNA in 21% of their saliva samples before, during, and after flight, and 7 astronauts shed VZV in 7.4% of their samples during and after flight. It was interesting that shedding of both EBV and VZV increased during the flight phase relative to before or after flight. In the case of CMV, 32% of urine samples from 8 subjects contained DNA of this virus. In normal healthy control subjects, EBV shedding was found in 3% and VZV and CMV were found in less than 1% of the samples. The circadian rhythm of salivary cortisol measured before, during, and after space flight did not show any significant difference between flight phases. These data show that increased reactivation of latent herpes viruses may be associated with decreased immune system function, which has been reported in earlier studies as well as in these same subjects (data not reported here).

    To examine the economic impact of providing herpes zoster vaccine (ZOS) in 19 affiliated supermarket pharmacies in a midwestern metropolitan area from the perspective of the pharmacy and to identify factors associated with greater rates of vaccine delivery and profitability. 19 affiliated supermarket pharmacies in the Kansas City metropolitan area. Immunizations with ZOS were expanded from 2 pharmacies to all 19 affiliated pharmacies. Various methods to promote the vaccine were used, including personal selling, store signage, and circular ads. In addition to a broad perspective pharmacoeconomic model, a localized perspective model is proposed to determine profitability for the service. Factors associated with greater success in vaccine delivery and profitability were identified. Net financial gains or losses were calculated for each vaccine administered for each of the 19 pharmacies and for the entire supermarket chain. 662 vaccines were given during the study period, accounting for 6.7% of all eligible patients. The profit per vaccine averaged $9.60 (5.7%) and $28.37 (18.9%) using the broad and localized perspective models, respectively. Success of the ZOS program was demonstrated using both models. Certain factors correlated with greater profits when using the localized perspective model.

    Herpes zoster (HZ) is primarily a disease of nerve tissue but the acute and longer-term manifestations require multidisciplinary knowledge and involvement in their management. Complications may be dermatological (e.g. secondary bacterial infection), neurological (e.g. long-term pain, segmental paresis, stroke), ophthalmological (e.g. keratitis, iridocyclitis, secondary glaucoma) or visceral (e.g. pneumonia, hepatitis). The age-related increased incidence of HZ and its complications is thought to be a result of the decline in cell-mediated immunity (immunosenescence), higher incidence of comorbidities with age and social-environmental changes. Individuals who are immunocompromised as a result of disease or therapy are also at increased risk, independent of age. HZ and its complications (particularly postherpetic neuralgia) create a significant burden for the patient, carers, healthcare systems and employers. Prevention and treatment of HZ complications remain a therapeutic challenge despite recent advances. This is an overview of the multidisciplinary implications and management of HZ in which the potential contribution of vaccination to reducing the incidence HZ and its complications are also discussed.

    Varicella-zoster virus (VZV) is a human herpesvirus. Primary infection causes varicella (chickenpox), a viremic illness typified by an exanthem consisting of several hundred vesicles. When VZV reactivates from latency in the spinal ganglia during late adulthood, the emerging virus causes a vesicular dermatomal rash (herpes zoster or shingles). To expand investigations of autophagy during varicella and zoster, newer 3D imaging technology was combined with laser scanning confocal microscopy to provide animations of autophagosomes in the vesicular rash. First, the cells were immunolabeled with antibodies against VZV proteins and the LC3 protein, an integral autophagosomal protein. Antibody reagents lacking activity against the human blood group A1 antigen were selected. After laser excitation of the samples, optimized emission detection bandwidths were configured by Zeiss Zen control software. Confocal Z-stacks comprising up to 40 optical slices were reconstructed into 3D animations with the aid of Imaris software. With this imaging technology, individual autophagosomes were clearly detectable as spheres within each vesicular cell. To enumerate the number of autophagosomes, data sets from 50 cells were reconstructed as 3D fluorescence images and analyzed with MeasurementPro software. The mean number of autophagosomes per infected vesicular cell was >100, although over 200 autophagosomes were seen in a few cells. In summary, macroautophagy was easily quantitated within VZV-infected cells after immunolabeling and imaging by 3D confocal animation technology. These same 3D imaging techniques will be applicable for investigations of autophagy in other virus-infected cells. Copyright © 2013 The Authors. Published by Elsevier B.V. All rights reserved.

    This study aimed to investigate the prevalence of human papilloma virus (HPV), herpes simplex virus-1/-2 (HSV-1/-2), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), cytomegalovirus (CMV), and human herpes virus-6/-7 (HHV-6/-7) in 23 human nasal polyps by applying PCR. Two types of control tissues were used: adjacent inferior/middle turbinates from the patients and inferior/middle turbinates from 13 patients undergoing nasal corrective surgery. EBV was the virus most frequently detected (35%), followed by HPV (13%), HSV-1 (9%), and CMV (4%). The CMV-positive polyp was simultaneously positive for HSV-1. HPV was also detected in the adjacent turbinates (4%) and the adjacent middle turbinate (4%) of one of the HPV-positive patients. EBV, HSV, and CMV were not detected in the adjacent turbinates of the EBV-, HSV- or CMV-positive patients. All mucosae were negative for the VZV, HHV-6, and HHV-7. This is the first study to deal with the involvement of a comparable group of viruses in human nasal polyposis. The findings support the theory that the presence of viral EBV markedly influences the pathogenesis of these benign nasal tumors. The low incidence of HPV detected confirms the hypothesis that HPV is correlated with infectious mucosal lesions to a lesser extent than it is with proliferative lesions, such as inverted papilloma. The low incidence of HSV-1 and CMV confirms that these two herpes viruses may play a minor role in the development of nasal polyposis. Double infection with HSV-1 and CMV may also play a minor, though causative, role in nasal polyp development. VZV and HHV-6/-7 do not appear to be involved in the pathogenesis of these mucosal lesions.

    To observe the effects of conventional western medication and joss stick moxibustion combined with pricking and cupping for herpes zoster in acute stage, and to explore its analgesic mechanism. Seventy patients with acute herpes zoster were randomized into an observation group (33 cases after 2 dropping) and a control group (34 cases after 1 dropping). Patients in the observation group were treated with joss stick moxibustion combined with pricking and cupping at local ashi points for 7 times, once every other day. Oral acyclovir, vitamin B 1 and mecobalamin tablets were applied in the control group for continuous 14 days, and interferon injection was used for continuous 6 days, etc. The herpes evaluation indexes of blister stopping time, scab time and decrustation time as well as pain intensity were observed before and after treatment. Peripheral serum substance P (SP) content of herpes local situation was detected. The comprehensive effects were evaluated. The blister stopping time, scab time and decrustation time in the observation group were shorter than those in the control group (all P 0.05). The pain beginning to ease time and duration time in the observation group were better than those in the control group (both P 0.05). The cured rate of the observation group was better than that of the control group [66.7% (22/33) vs 58.8% (20/34), P cupping are effective for herpes zoster, which have quicker and good analgesic effects than conventional western medication. Its mechanism may be related to reducing the content of SP more fast and to a larger degree.

    Accumulating evidence indicates that herpes zoster (HZ) may increase the risk of stroke/transient ischemic attack (TIA) or myocardial infarction (MI), but the results are inconsistent. We aim to explore the relationship between HZ and risk of stroke/TIA or MI and between herpes zoster ophthalmicus (HZO) and stroke. We estimated the relative risk (RR) and 95% confidence intervals (CIs) with the meta-analysis. Cochran's Q test and Higgins I 2 statistic were used to check for heterogeneity. HZ infection was significantly associated with increased risk of stroke/TIA (RR = 1.30, 95% CI: 1.17-1.46) or MI (RR = 1.18, 95% CI: 1.07-1.30). The risk of stroke after HZO was 1.91 (95% CI 1.32-2.76), higher than that after HZ. Subgroup analyses revealed increased risk of ischemic stroke after HZ infection but not hemorrhagic stroke. The risk of stroke was increased more at 1 month after HZ infection than at 1-3 months, with a gradual reduced risk with time. The risk of stroke after HZ infection was greater with age less than 40 years than 40-59 years and more than 60 years. Risk of stroke with HZ infection was greater without treatment than with treatment and was greater in Asia than Europe and America but did not differ by sex. Our study indicated that HZ infection was associated with increased risk of stroke/TIA or MI, and HZO infection was the most marked risk factor for stroke. Further studies are needed to explore whether zoster vaccination could reduce the risk of stoke/TIA or MI. Copyright © 2017 National Stroke Association. Published by Elsevier Inc.

    2012-03-01

    Our objective was to determine whether a three-week complementary and alternative medicine (CAM) approach integrating several therapies from Traditional Chinese Medicine (TCM) along with neural therapy (injection of 1% procaine as local anesthesia) reduces the level of unresolved pain associated with herpes zoster. The design was a randomized controlled clinical trial in a community-based primary care clinic in Toronto, Ontario. We studied individuals 18 years of age and older with a confirmed diagnosis of herpes zoster of at least 30 days duration and with at least moderate postherpetic neuralgia pain (≥4) on a 10-point Likert scale. The CAM therapies used were acupuncture, neural therapy (1% procaine injection as a local anesthetic), cupping and bleeding, and TCM herbs. An immediate treatment group (n=32) received the CAM intervention once daily, five days per week, for three weeks. A wait-list (delayed treatment) group (n=27) was used as a control and received the same treatment starting three weeks after randomization. This three-week time period, when one group was receiving active CAM treatment and the other was not, was used as basis of comparison for treatment effects between groups. Pain, quality of life, and depression were measured at baseline, and three, six, and nine weeks post-randomization. Patients were followed for up to two years. Participants had a mean age of 69.8 years (SD=11.1) and had had herpes zoster-related pain for a median of 4.8 months (range: 1 month to 15 years). The immediate treatment and control groups had similar pain levels at baseline (treatment = 7.5; control = 7.8; p=0.5; scores based on the 10-point Likert pain scale). At three weeks post-randomization (i.e., after the immediate treatment group completed treatment) pain scores differed significantly (treatment = 2.3; control = 7.2; ppain in the immediate treatment group was maintained at nine weeks and at long-term follow-up (one to two years later).

    In 2013, a herpes zoster vaccination programme was introduced in England for adults aged 70 years with a phased catch-up programme for those aged 71-79 years. We aimed to evaluate the effect of the first 3 years of the vaccination programme on incidence of herpes zoster and postherpetic neuralgia in this population. In this population-based study, we extracted data from the Royal College of General Practitioners sentinel primary care network on consultations with patients aged 60-89 years for herpes zoster and postherpetic neuralgia occurring between Oct 1, 2005, and Sept 30, 2016, obtaining data from 164 practices. We identified individual data on herpes zoster vaccinations administered and consultations for herpes zoster and postherpetic neuralgia, and aggregated these data to estimate vaccine coverage and incidence of herpes zoster and postherpetic neuralgia consultations. We defined age cohorts to identify participants targeted in each year of the programme, and as part of the routine or catch-up programme. We modelled incidence according to age, region, gender, time period, and vaccine eligibility using multivariable Poisson regression with an offset for person-years. Our analysis included 3·36 million person-years of data, corresponding to an average of 310 001 patients aged 60-89 years who were registered at an RCGP practice each year. By Aug 31, 2016, uptake of the vaccine varied between 58% for the recently targeted cohorts and 72% for the first routine cohort. Across the first 3 years of vaccination for the three routine cohorts, incidence of herpes zoster fell by 35% (incidence rate ratio 0·65 [95% 0·60-0·72]) and of postherpetic neuralgia fell by 50% (0·50 [0·38-0·67]). The equivalent reduction for the four catch-up cohorts was 33% for herpes zoster (incidence rate ratio 0·67 [0·61-0·74]) and 38% for postherpetic neuralgia (0·62 [0·50-0·79]). These reductions are consistent with a vaccine effectiveness of about 62% against herpes zoster

    We present the case of a 54-year-old man who developed progressive outer retinal necrosis (PORN) as an initial manifestation of HIV infection without any significant risk factors for infection with HIV. PORN is usually found as a manifestation of known AIDS late in the disease. Our patient presented with transient visual loss followed by decrease in visual acuity and facial rash. Subsequent investigation revealed anterior chamber tap positive for varicella zoster virus (VZV), as well as HIV positivity, with an initial CD4 count of 48 cells/µL. Systemic and intravitreal antivirals against VZV, and highly active antiretroviral therapy against HIV were started, which halted further progression of retinal necrosis. This case highlights the importance of suspecting PORN where there is a rapidly progressive retinitis, and also testing the patient for HIV, so appropriate treatment can be started. 2015 BMJ Publishing Group Ltd.

    Herpes zoster has a high incidence rate among people aged ≥ 60 years and can lead to serious complications such as post-herpetic neuralgia. There are currently no data on the economic burden of herpes zoster and post-herpetic neuralgia in Japan, and the objective of this study was to address this gap. A total of 412 patients aged ≥ 60 years diagnosed with herpes zoster were recruited. Demographic, clinical, and healthcare resource utilization data on patients with herpes zoster or post-herpetic neuralgia collected via case report forms were used to estimate direct medical cost. Data obtained from a questionnaire survey among patients with herpes zoster/post-herpetic neuralgia were used to estimate transportation cost and productivity loss. The mean number of outpatient visits was 5.7. Prescription medications were the main cost driver accounting for 60% of the direct medical cost. The mean direct medical and total herpes zoster-related costs per patient were ¥43,925 and ¥57,112, respectively, and were higher in patients with post-herpetic neuralgia than in those with herpes zoster without complications. Direct medical cost represented 77%, productivity loss 19%, and transportation cost 4% of the total. This is the first study of the economic burden of herpes zoster and post-herpetic neuralgia in Japan and it demonstrated substantial direct medical cost as a result of the multiple outpatient visits and prescription medications required. These findings provide baseline data for possible future economic evaluations of new herpes zoster/post-herpetic neuralgia interventions. This cost analysis is part of a prospective, physician practice-based cohort study conducted between June 2013 and February 2015 in Kushiro, Japan (Clinicaltrials.gov identifier NCT01873365, registered on 6 June, 2013).

    In phase III trials, 2 doses of a herpes zoster (HZ) subunit vaccine (HZ/su; 50 µg varicella-zoster virus glycoprotein E [gE] and AS01 B Adjuvant System) administered 2-months apart in older adults (≥50 and ≥70 years) demonstrated >90% efficacy in preventing HZ and had a clinically acceptable safety profile. Here we report immunogenicity, reactogenicity and safety following administration of 2 HZ/su doses at intervals longer than 2 months. In this Phase III, open-label trial conducted in the US and Estonia, 354 adults ≥50 years were randomized 1:1:1 to receive 2 HZ/su doses 2, 6, or 12 months apart. gE-specific humoral immune responses were evaluated at pre-vaccination, 1 and 12 months post-dose 2. Co-primary objectives were to compare immune responses to HZ/su 1 month post-dose 2 when given 6-months or 12-months apart to those administered 2-months apart. For each participant, safety information was collected from dose 1 to 12 months post-dose 2. 346 participants completed the study and 343 were included in the according-to-protocol cohort for immunogenicity. One month post-dose 2, vaccine response rates were 96.5% (97.5% confidence interval [CI]: 90.4; 99.2) and 94.5% (97.5% CI: 87.6; 98.3) for the 0, 6- and 0, 12-month schedules, respectively, both schedules meeting the pre-defined criterion. Non-inferiority of anti-gE geometric mean concentrations was demonstrated for HZ/su administered on 0, 6-month compared to a 0, 2-month schedule; however, HZ/su administered on a 0, 12-month schedule did not meet the non-inferiority criterion. Injection site pain was the most commonly reported solicited adverse event (AE). 26 participants each reported at least 1 serious AE; none were assessed as related to vaccination. Immune responses to HZ/su administered at 0, 6-month were non-inferior to those elicited by a 0, 2-month schedule. HZ/su exhibited a clinically acceptable safety profile for all dosing intervals.

    Objective To determine the incidence, time trends, risk factors and severity of herpes zoster (HZ) in a population-based incidence cohort of patients with rheumatoid arthritis (RA) compared to a group of individuals without RA from the same population. Methods All residents of Olmsted County, MN who first fulfilled 1987 American College of Rheumatology criteria for RA between 1/1/1980 and 12/31/2007 and a cohort of similar residents without RA were assembled and followed by retrospective chart review until death, migration, or 12/31/2008. Results There was no difference in the presence of HZ prior to RA incidence/index date between the cohorts (p=0.85). During follow-up 84 patients with RA (rate: 12.1 per 1000 person-years) and 44 subjects without RA (rate: 5.4 per 1000 person-years) developed HZ. Patients with RA were more likely to develop HZ than those without RA (hazard ratio: 2.4; 95% confidence interval: 1.7, 3.5). Patients diagnosed with RA in 1995–2007 had a higher likelihood of developing HZ than those diagnosed in 1980–1994. Erosive disease, previous joint surgery, use of hydroxychloroquine and corticosteroids were significantly associated with the development of HZ in RA, while the use of methotrexate or biologic agents was not. Complications of HZ occurred at a similar rate in both cohorts. Conclusion The incidence of HZ is increased in RA and has risen in recent years. The increasing incidence of HZ in more recent years is also noted in the general population. RA disease severity is associated with development of HZ. PMID:23281295

    Full Text Available This study provides data to define an efficient biocide-free strategy based on zosteric acid to counteract biofilm formation on the membranes of submerged bioreactor system plants. 16S rRNA gene phylogenetic analysis showed that gammaproteobacteria was the prevalent taxa on fouled membranes of an Italian wastewater plant. Pseudomonas was the prevalent genus among the cultivable membrane-fouler bacteria and Pseudomonas putida was selected as the target microorganism to test the efficacy of the antifoulant. Zosteric acid was not a source of carbon and energy for P. putida cells and, at 200 mg/L, it caused a reduction of bacterial coverage by 80%. Biofilm experiments confirmed the compound caused a significant decrease in biomass (−97% and thickness (−50%, and it induced a migration activity of the peritrichous flagellated P. putida over the polycarbonate surface not amenable to a biofilm phenotype. The low octanol-water partitioning coefficient and the high water solubility suggested a low bioaccumulation potential and the water compartment as its main environmental recipient and capacitor. Preliminary ecotoxicological tests did not highlight direct toxicity effects toward Daphnia magna. For green algae Pseudokirchneriella subcapitata an effect was observed at concentrations above 100 mg/L with a significant growth of protozoa that may be connected to a concurrent algal growth inhibition.

    We developed a highly sensitive and specific assay for the rapid detection of smallpox virus DNA on both the Smart Cycler and LightCycler platforms. The assay is based on TaqMan chemistry with the orthopoxvirus hemagglutinin gene used as the target sequence. With genomic DNA purified from variola virus Bangladesh 1975, the limit of detection was estimated to be approximately 25 copies on both machines. The assay was evaluated in a blinded study with 322 coded samples that included genomic DNA from 48 different isolates of variola virus; 25 different strains and isolates of camelpox, cowpox, ectromelia, gerbilpox, herpes, monkeypox, myxoma, rabbitpox, raccoonpox, skunkpox, vaccinia, and varicella-zoster viruses; and two rickettsial species at concentrations mostly ranging from 100 fg/μl to 1 ng/μl. Contained within those 322 samples were variola virus DNA, obtained from purified viral preparations, at concentrations of 1 fg/μl to 1 ng/μl. On the Smart Cycler platform, 2 samples with false-positive results were detected among the 116 samples not containing variola virus tested; i.e., the overall specificity of the assay was 98.3%. On the LightCycler platform, five samples with false-positive results were detected (overall specificity, 95.7%). Of the 206 samples that contained variola virus DNA ranging in concentrations from 100 fg/μl to 1 ng/μl, 8 samples were considered negative on the Smart Cycler platform and 1 sample was considered negative on the LightCycler platform. Thus, the clinical sensitivities were 96.1% for the Smart Cycler instrument and 99.5% for the LightCycler instrument. The vast majority of these samples were derived from virus-infected cell cultures and variola virus-infected tissues; thus, the DNA material contained both viral DNA and cellular DNA. Of the 43 samples that contained purified variola virus DNA ranging in concentration from 1 fg/μl to 1 ng/μl, the assay correctly detected the virus in all 43 samples on both the Smart Cycler

    Interleukin (IL)-33 is released on cell injury and activates the immune reaction. IL-33 is involved in antiviral reaction in herpes virus infection, but the source that secretes IL-33 has not been identified. We speculate that keratinocytes injured in herpes virus infection secrete IL-33. In order to detect IL-33 in the lesional epidermis of patients with herpes virus infection, we immunostained several cutaneous herpes virus infection samples with an anti-IL-33 antibody, and compared them with cutaneous human papilloma virus (HPV) infection samples. We observed strong nuclear and mild cytoplasmic staining in epidermal keratinocytes of the lesional skin samples with herpes simplex virus and varicella zoster virus infections. However, staining was not observed in the epidermis of verruca vulgaris (VV) samples. We assumed that the strong immune reaction to herpes virus infection may depend on strong IL-33 expression in the epidermis, while very weak immune reaction in samples from patients with VV may be due to low or no expression of IL-33 in the lesional epidermis. © 2018 Japanese Dermatological Association.

    Objective: Herpes zoster (HZ) can develop into postherpetic neuralgia (PHN), which is a chronic neuropathic pain (NP). Whether the chronification from HZ to PHN induced brain functional or structural change is unknown and no study compared the changes of the same brains of patients who transited from HZ to PHN. We minimized individual differences and observed whether the chronification of HZ to PHN induces functional and pain duration dependent grey matter volume (GMV) change in HZ-PHN patients. Methods: To minimize individual differences induced error, we enrolled 12 patients with a transition from HZ to PHN. The functional and structural changes of their brains between the two states were identified with resting-state functional MRI (rs-fMRI) technique (i.e., the regional homogeneity (ReHo) and fractional aptitude of low-frequency fluctuation (fALFF) method) and the voxel based morphometry (VBM) technology respectively. The correlations between MRI parameters (i.e., ΔReHo, ΔfALFF and ΔVBM) and Δpain duration were analyzed too. Results: Compared with HZ brains, PHN brains exhibited abnormal ReHo, fALFF and VBM values in pain matrix (the frontal lobe, parietal lobe, thalamus, limbic lobe and cerebellum) as well as the occipital lobe and temporal lobe. Nevertheless, the activity of vast area of cerebellum and frontal lobe significantly increased while that of occipital lobe and limbic lobe showed apparent decrease when HZ developed to PHN. In addition, PHN brain showed decreased GMV in the frontal lobe, the parietal lobe and the occipital lobe but increased in the cerebellum and the temporal lobe. Correlation analyses showed that some of the ReHo, fALFF and VBM differential areas (such as the cerebellum posterior lobe, the thalamus extra-nuclear and the middle temporal gyrus) correlated well with Δpain duration. Conclusions: HZ chronification induced functional and structural change in cerebellum, occipital lobe, temporal lobe, parietal lobe and limbic lobe

    Patients with rheumatoid arthritis (RA) are at increased risk of herpes zoster (HZ), and the risk appears to be increased in patients treated with tofacitinib. The aim of this study was to evaluate whether concomitant treatment with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) or glucocorticoids (GCs) contributes to the increased risk of HZ in RA patients treated with tofacitinib. HZ cases were identified from the databases of 2 phase I, 9 phase II, 6 phase III, and 2 long-term extension studies of tofacitinib in RA patients. Crude incidence rates (IRs) of all HZ events (serious and nonserious) per 100 patient-years (with 95% confidence intervals [95% CIs]) were calculated for unique patients. Within phase III studies, we described HZ rates according to concomitant csDMARD treatment and baseline GC use. A multivariable Cox proportional hazards regression model was used to evaluate HZ risk factors across studies. Across all studies (6,192 patients; 16,839 patient-years), HZ was reported in 636 tofacitinib-treated patients (IR 4.0, 95% CI 3.7-4.4). In most cases (93%), HZ was classified as nonserious, and the majority of patients (94%) had involvement of only 1 dermatome. HZ IRs varied across regions, from 2.4 (95% CI 2.0-2.9) in Eastern Europe to 8.0 (95% CI 6.6-9.6) in Japan and 8.4 (95% CI 6.4-10.9) in Korea. Within phase III studies, HZ IRs varied according to tofacitinib dose, background csDMARD treatment, and baseline use of GCs. The IRs were numerically lowest for monotherapy with tofacitinib 5 mg twice daily without GCs (IR 0.56 [95% CI 0.07-2.01]) and highest for tofacitinib 10 mg twice daily with csDMARDs and GCs (IR 5.44 [95% CI 3.72-7.68]). Age, GC use, tofacitinib dose, and enrollment within Asia were independent risk factors for HZ. Patients receiving treatment with tofacitinib and GCs appear to have a greater risk of developing HZ compared with patients receiving tofacitinib monotherapy without GCs. © 2017 The Authors

    Reactivation of latent viruses is a recognized consequence of decreased immunity. More recently viral reactivation has been identified as an important in vivo indicator of clinically relevant immune changes. Viral reactivation can be determined quickly and easily by the presence of virus in saliva and other body fluids. Real-time polymerase chain reaction (PCR) is a highly sensitive and specific molecular method to detect the presence of specific viral DNA. Studies in astronauts demonstrated that herpes simplex virus type 1(HSV-1), Epstein-Barr Virus (EBV), cytomegalovirus (CMV), and varicella zoster virus (VZV) reactivate at rates above normal during and after spaceflight in response to moderately decreased T-cell immunity. This technology was expanded to patients on Earth beginning with human immune deficiency virus (HIV) immuno-compromised patients. The HIV patients shed EBV in saliva at rates 9-fold higher than observed in astronauts demonstrating that the level of EBV shedding reflects the severity of impaired immunity. Whereas EBV reactivation is not expected to produce serious effects in astronauts on missions of 6 months or less, VZV reactivation in astronauts could produce shingles. Reactivation of live, infectious VZV in astronauts with no symptoms was demonstrated in astronauts during and after spaceflight. We applied our technology to study VZV-induced shingles in patients. In a study of 54 shingles patients, we showed salivary VZV was present in every patient on the day antiviral (acyclovir) treatment was initiated. Pain and skin lesions decreased with antiviral treatment. Corresponding decreases in levels of VZV were also observed and accompanied recovery. Although the level of VZV in shingles patients before the treatment was generally higher than those found in astronauts, lower range of VZV numbers in shingles patients overlapped with astronaut s levels. This suggests a potential risk of shingles to astronauts resulting from reactivation of VZV. In

    Declining telomere length (TL) is associated with T cell senescence. While TL in naïve and memory T cells declines with increasing age, there is limited data on TL dynamics in virus-specific memory CD4+ T cells in healthy adults. We combined BrdU-labeling of virus-stimulated T cells followed with flow cytometry-fluorescent in situ hybridization for TL determination. We analyzed TL in T cells specific for several virus infections: non-recurring acute (vaccinia virus, VACV), recurring-acute (influenza A virus, IAV), and reactivating viruses (varicella-zoster virus, VZV, and cytomegalovirus, CMV) in 10 healthy subjects. Additionally, five subjects provided multiple blood samples separated by up to 10 years. VACV- and CMV-specific T cells had longer average TL than IAV-specific CD4+ T cells. Although most virus-specific cells were CD45RA-, we observed a minor population of BrdU+ CD45RA+ T cells characterized by long telomeres. Longitudinal analysis demonstrated a slow decline in average TL in virus-specific T cells. However, in one subject, VZV reactivation led to an increase in average TL in VZV-specific memory T cells, suggesting a conversion of longer TL cells from the naïve T cell repertoire. TLs in memory CD4+ T cells in otherwise healthy adults are heterogeneous and follow distinct virus-specific kinetics. These findings suggests that the distribution of TL and the creation and maintenance of long TL memory T cells could be important for the persistence of long-lived T cell memory.

    Phytophthora sp. is a genus in the oomycetes, which are similar to filamentous fungi in morphology and habitat, but phylogenetically more closely related to brown algae and diatoms and fall in the kingdom Stramenopila. In the past few years, several viruses have been characterized in Phytophthora species, including four viruses from Phytophthora infestans, the late blight pathogen, and an endornavirus from an unnamed Phytophthora species from Douglas fir. Studies on Phytophthora viruses have revealed several interesting systems. Phytophthora infestans RNA virus 1 (PiRV-1) and PiRV-2 are likely the first members of two new virus families; studies on PiRV-3 support the establishment of a new virus genus that is not affiliated with established virus families; PiRV-4 is a member of Narnaviridae, most likely in the genus Narnavirus; and Phytophthora endornavirus 1 (PEV1) was the first nonplant endornavirus at the time of reporting. Viral capsids have not been found in any of the above-mentioned viruses. PiRV-1 demonstrated a unique genome organization that requires further examination, and PiRV-2 may have played a role in late blight resurgence in 1980s-1990s. Copyright © 2013 Elsevier Inc.

    Full Text Available There is little evidence regarding the effectiveness of intervention methods in the treatment of zoster-related pain (ZAP after the acute phase of zoster. Generally, if ZAP remains after more than 180 days from its onset, the likelihood of pain reduction is very low; this condition is considered as a "well established" post-herpetic neuralgia (PHN. Although the clinical efficacy of intrathecal steroid injection and spinal cord stimulation (SCS for ZAP management has been reported, these interventions are not widely used due to inherent disadvantages. Continuous epidural block is widely used in clinical practice, and the effectiveness of pulsed radiofrequency (PRF to the dorsal root ganglion (DRG in the treatment of ZAP already has been reported.The purpose of this study was to compare the clinical efficacy of continuous epidural block and DRG PRF beyond acute phase of zoster, bur before PHN was well established (from 30 days to180 days after zoster onset.Retrospective comparative study.A total of 42 medical records were analyzed. Patients were divided into two groups according to the type of procedure utilized: continuous epidural block (continuous epidural group and DRG PRF (PRF group. The clinical efficacy of the procedure was evaluated using a numeric rating scale (NRS and the medication dose before and 1 to 6 months after the procedure.There was a significant decrease in the NRS value with time in both groups. However, this decrease was more significant in the PRF group than in the continuous epidural group. The medication doses decreased significantly in the PRF group over time, but not in the continuous epidural group. The rate of clinically meaningful PHN (NRS≥3 was also lower in the PRF group than in the continuous epidural group.This study revealed that DRG PRF was more effective than a continuous epidural block in treating ZAP after the acute phase of zoster. A neuromodulation method such as DRG PRF may be a useful option for

    In the last decade many commercial biocides were gradually banned for toxicity. This work reports, for the first time, the synthesis and characterization of silica nanocontainers loaded with a natural product antifoulant (NPA), the zosteric sodium salt which is a non-commercial and environmentally friendly product with natural origin. The synthesis approach is a single step dynamic self-assembly with tetraethoxysilane (TEOS) as silica precursor. Unlike conventional mesoporous silica nanoparticles, the structure of these silica nanocontainers provides loading capacity and allows prolonged release of biocide species. The obtained nanocapsules have been characterized morphologically by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The encapsulation was checked by FTIR ATR spectroscopy and thermogravimetric analyses. The results of the release studies show the great potential of the here presented newly developed nanofillers in all applications where a controlled release of non-toxic and environmentally friendly biocides is required.

    A 15-year postmarketing evaluation of the impact of varicella vaccine on the age distribution of varicella disease is being conducted at Kaiser Permanente Medical Care Program, Northern California (KPMCP). We report on a baseline assessment of the age-specific incidence and hospitalization rates of varicella and herpes zoster that was conducted before vaccine introduction. To assess the annual incidence of varicella, a telephone survey was conducted in a random sample of approximately 8,000 youths 5 to 19 years of age. The annual incidence of hospitalizations for varicella and herpes zoster in 1994 was assessed with the use of the computerized database at KPMCP. Varicella annual incidence was 10.3% in 5- to 9-year-olds, 1.9% in 10- to 14-year-olds and 1.2% in the 15- to 19-year age groups, respectively. Hospitalization rates among the entire KPMCP membership were 2.6 and 2.1 per 100,000 person years for varicella and zoster, respectively. Varicella incidence in the 15- to 19-year age group was higher among African-Americans than among Caucasians. Varicella rates were similar in the 5- to 9- and 10- to 14-year age groups to rates from other published studies conducted in 1972 to 1978, 1980 to 1988 and 1990 to 1992; however, the rate in 15- to 19-year-olds was 2 to 4 times higher than published rates in the same age category.

    Ganjam virus (GANV), a member of genus Nairovirus of family Bunyavirdae is of considerable veterinary importance in India. Though, predominantly tick borne, GANV was also isolated from mosquitoes, man and sheep. Neutralizing and complement fixing antibodies to GANV have been detected in animal and human sera collected from different parts of the country. Thirty three strains of GANV have been isolated from India, mainly from Haemaphysalis ticks. The virus replicated in certain vertebrate and mosquito cell lines and found pathogenic to laboratory animals. One natural infection and five laboratory-acquired infections in men were also reported. GANV is antigenically related to Nairobi sheep disease virus (NSDV) of Africa, which is highly pathogenic for sheep and goats causing 70-90 per cent mortality among the susceptible population. Recent molecular studies have demonstrated that GANV is an Asian variant of NSDV and both these viruses are related to the dreaded Crimean Congo haemorrhagic fever (CCHF) group viruses. The versatility of the virus to replicate in different arthropod species, its ability to infect sheep, goat and man makes it an important zoonotic agent.

    Several studies have indicated that viral reactivations following allogeneic hematopoietic stem cell transplantation (allo-HSCT) are frequent, but viral reactivations after autologous HSCT (auto-HSCT) have not been investigated in detail. We performed multiplex polymerase chain reaction (PCR) assay to examine multiple viral reactivations simultaneously in 24 patients undergoing auto-HSCT between September 2010 and December 2012. Weekly whole blood samples were collected from pre- to 42 days post-HSCT, and tested for the following 13 viruses; herpes simplex virus 1 (HSV-1), HSV-2, varicella-zoster virus (VZV), Epstein-Barr virus (EBV), cytomegalovirus (CMV), human herpesvirus 6 (HHV-6), HHV-7, HHV-8, adeno virus (ADV), BK virus (BKV), JC virus (JCV), parvovirus B19 (B19V), and hepatitis B virus (HBV).  Fifteen (63%) patients had at least one type of viral reactivation. HHV6 (n = 10; 41.7%) was most frequently detected followed by EBV (n = 7; 29.2%). HHV-6 peaked on day 21 after HSCT and promptly declined. In addition, HBV, CMV, HHV7, and B19V were each detected in one patient. HHV6 reactivation was detected in almost half the auto-HSCT patients, which was similar to the incidence in allo-HSCT patients. The incidence of EBV was unexpectedly high. Viral infections in patients undergoing auto-HSCT were higher than previously reported in other studies. Although there were no particular complications of viral infection, we should pay attention to possible viral reactivations in auto-HSCT patients. J. Med.

    Cerebral ischaemia caused by inflammatory vasculopathies has been described as complication of human immunodeficiency virus (HIV) infection. Imaging studies have shown ischaemic lesions and changes of the vascular lumen, but did not allow demonstration of abnormalities within the vessel wall itself. Two HIV-infected men presented with symptoms of a transient ischaemic attack. Initial MRI of the first showed no infarct; in the second two small lacunar lesions were detected. In both cases, multiplanar 3-mm slice contrast-enhanced T1-weighted images showed aneurysmal dilatation, with thickening and contrast enhancement of the wall of the internal carotid and middle cerebral (MCA) arteries. These findings were interpreted as indicating cerebral vasculitis. In the first patient the vasculopathy progressed to carotid artery occlusion, and he developed an infarct in the MCA territory, but then remained neurologically stable. In the second patient varicella zoster virus (VZV) infection was the probable cause of vasculitis. The clinical deficits and vasculitic MRI changes regressed with antiviral and immunosuppressive therapy. (orig.)

Two HIV-infected men presented with symptoms of a transient ischaemic attack. Initial MRI of the first showed no infarct; in the second two small lacunar lesions were detected. In both cases, multiplanar 3-mm slice contrast-enhanced T1-weighted images showed aneurysmal dilatation, with thickening and contrast enhancement of the wall of the internal carotid and middle cerebral (MCA) arteries. These findings were interpreted as indicating cerebral vasculitis. In the first patient the vasculopathy progressed to carotid artery occlusion, and he developed an infarct in the MCA territory, but then remained neurologically stable. In the second patient varicella zoster virus (VZV) infection was the probable cause of vasculitis. The clinical deficits and vasculitic MRI changes regressed with antiviral and immunosuppressive therapy. (orig.)

    The psychopathological symptoms occurring in the course of diseases associated with infections are often initially isolated and non-characteristic, and may cause diagnostic difficulties. Moreover, such disorders tend to be less responsive to psychiatric management. Among possible causes such as trauma, neoplasm and vascular changes, inflammatory changes of the brain as a result of a viral infection should also be considered. There were 452 registered cases of viral encephalitis in Poland in 2010, and although not very prevalent they remain a severe and life-threatening condition. What is more, the frequently occurring neurological and psychiatric complications of viral encephalitis often result in permanent disabilities, causing a significant decrease in the quality of life. This article presents the three types of encephalitis that are most prevalent among immunocompetent patients in Poland, i.e. herpes simplex encephalitis (HSE), tick-borne encephalitis (TBE) and herpes zoster encephalitis (HZE). The psychopathology of the acute phase of the infection, the residual symptoms, features apparent in imaging studies and some neuropathological aspects are also presented. The paper also focuses on psychiatric aspects of the diagnostics and treatment of the described conditions. The clinical pictures of these infections are quite specific, although they cover a wide range of symptoms, and these characteristic features are described. The aim of this review is also to show the significance of thorough diagnostics and a multidisciplinary approach to patients with viral CNS infections.

    Epidemiological studies suggest that reduced exposure to varicella might lead to an increased risk for herpes zoster (HZ). Reduction of exposure to varicella is a consequence of varicella vaccination but also of demographic changes. We analyzed how the combination of vaccination programs and demographic dynamics will affect the epidemiology of varicella and HZ in Germany over the next 50 years. We used a deterministic dynamic compartmental model to assess the impact of different varicella and HZ vaccination strategies on varicella and HZ epidemiology in three demographic scenarios, namely the projected population for Germany, the projected population additionally accounting for increased immigration as observed in 2015/2016, and a stationary population. Projected demographic changes alone result in an increase of annual HZ cases by 18.3% and a decrease of varicella cases by 45.7% between 1990 and 2060. Independently of the demographic scenario, varicella vaccination reduces the cumulative number of varicella cases until 2060 by approximately 70%, but also increases HZ cases by 10%. Unlike the currently licensed live attenuated HZ vaccine, the new subunit vaccine candidate might completely counteract this effect. Relative vaccine effects were consistent across all demographic scenarios. Demographic dynamics will be a major determinant of HZ epidemiology in the next 50 years. While stationary population models are appropriate for assessing vaccination impact, models incorporating realistic population structures allow a direct comparison to surveillance data and can thus provide additional input for immunization decision-making and resource planning.

    Full Text Available Abstract Background The determination of virus-specific immunoglobulin G (IgG antibodies in cerebrospinal fluid (CSF is useful for the diagnosis of virus associated diseases of the central nervous system (CNS and for the detection of a polyspecific intrathecal immune response in patients with multiple sclerosis. Quantification of virus-specific IgG in the CSF is frequently performed by calculation of a virus-specific antibody index (AI. Determination of the AI is a demanding and labour-intensive technique and therefore automation is desirable. We evaluated the precision and the diagnostic value of a fully automated enzyme immunoassay for the detection of virus-specific IgG in serum and CSF using the analyser BEP2000 (Dade Behring. Methods The AI for measles, rubella, varicella-zoster, and herpes simplex virus IgG was determined from pairs of serum and CSF samples of patients with viral CNS infections, multiple sclerosis and of control patients. CSF and serum samples were tested simultaneously with reference to a standard curve. Starting dilutions were 1:6 and 1:36 for CSF and 1:1386 and 1:8316 for serum samples. Results The interassay coefficient of variation was below 10% for all parameters tested. There was good agreement between AIs obtained with the BEP2000 and AIs derived from the semi-automated reference method. Conclusion Determination of virus-specific IgG in serum-CSF-pairs for calculation of AI has been successfully automated on the BEP2000. Current limitations of the assay layout imposed by the analyser software should be solved in future versions to offer more convenience in comparison to manual or semi-automated methods.

    Despite the frequency of infections with herpesviridae family, only eight subtypes affect humans (Herpex Simplex Virus types 1 and 2, Varicella Zoster Virus, Epstein-Barr Virus, Citomegalovirus and Human Herpes Virus types 6, 7 and 8). Amongst enteroviruses infections, the most important are Poliovirus, Coxackievirus and Echovirus. Symptoms can vary from mild to severe and early diagnosis is of upmost importance. Nowadays, low-density arrays can detect different types of viruses in a single assay using DNA extracted from biological samples. We analyzed 70 samples of formalin-fixed and paraffin-embedded tissue, searching for viruses (HSV-1, HSV-2, VZV, CMV, EBV, HHV-6, HHV-7 y HHV-8, Poliovirus, Echovirus and Coxsackievirus) using the kit CLART ® ENTHERPEX. Out of the total of 70 samples, 29 were positive for viral infection (41.43%), and only 4 of them showed cytopathic effect (100% correlation between histology and the test). 47.6% of GVHD samples were positive for virus; 68.75% of IBD analyzed showed positivity for viral infection; in colitis with ulcers (neither GVHD nor IBD), the test was positive in 50% of the samples and was also positive in 50% of ischemic lesions. The high sensitivity of the technique makes it a useful tool for the pathologist in addition to conventional histology-based diagnosis, as a viral infection may affect treatment.

    This phase III, non-randomized, open-label, multi-center study (NCT01827839) evaluated the immunogenicity and safety of an adjuvanted recombinant subunit herpes zoster (HZ) vaccine (HZ/su) in adults aged ≥ 50 y with prior physician-documented history of HZ. Participants (stratified by age: 50-59, 60-69 and ≥ 70 y) received 2 doses of HZ/su 2 months apart and were followed-up for another 12 months. Anti-glycoprotein E (gE) antibodies were measured by enzyme-linked immunosorbent assay before vaccination and 1 month after the second dose (Month 3). Solicited local and general adverse events (AEs) were recorded for 7 d and unsolicited AEs for 30 d after each vaccination. Serious AEs were recorded until study end. The primary immunogenicity objective was met if the lower limit of the 95% confidence interval (CI) of the vaccine response rate (VRR), defined as a 4-fold increase in anti-gE over baseline, at Month 3 was ≥ 60%. 96 participants (32/age group) were enrolled. The primary immunogenicity objective was met, as the VRR at Month 3 was 90.2% (95% CI: 81.7-95.7). Geometric mean anti-gE antibody concentrations at Month 3 were similar across age groups. 77.9% and 71.6% of participants reported local and general solicited AEs, respectively. The most frequent solicited AEs were pain at injection site, fatigue, headache, myalgia and shivering. The HZ/su vaccine was immunogenic in adults aged ≥ 50 y with a physician-documented history of HZ, and no safety concerns were identified.

  9. Pseudorabies virus infection alters neuronal activity and connectivity in vitro.

    Full Text Available Alpha-herpesviruses, including human herpes simplex virus 1 & 2, varicella zoster virus and the swine pseudorabies virus (PRV, infect the peripheral nervous system of their hosts. Symptoms of infection often include itching, numbness, or pain indicative of altered neurological function. To determine if there is an in vitro electrophysiological correlate to these characteristic in vivo symptoms, we infected cultured rat sympathetic neurons with well-characterized strains of PRV known to produce virulent or attenuated symptoms in animals. Whole-cell patch clamp recordings were made at various times after infection. By 8 hours of infection with virulent PRV, action potential (AP firing rates increased substantially and were accompanied by hyperpolarized resting membrane potentials and spikelet-like events. Coincident with the increase in AP firing rate, adjacent neurons exhibited coupled firing events, first with AP-spikelets and later with near identical resting membrane potentials and AP firing. Small fusion pores between adjacent cell bodies formed early after infection as demonstrated by transfer of the low molecular weight dye, Lucifer Yellow. Later, larger pores formed as demonstrated by transfer of high molecular weight Texas red-dextran conjugates between infected cells. Further evidence for viral-induced fusion pores was obtained by infecting neurons with a viral mutant defective for glycoprotein B, a component of the viral membrane fusion complex. These infected neurons were essentially identical to mock infected neurons: no increased AP firing, no spikelet-like events, and no electrical or dye transfer. Infection with PRV Bartha, an attenuated circuit-tracing strain delayed, but did not eliminate the increased neuronal activity and coupling events. We suggest that formation of fusion pores between infected neurons results in electrical coupling and elevated firing rates, and that these processes may contribute to the altered neural

    Stroke and TIA are recognized complications of acute herpes zoster (HZ). Herein, we evaluate HZ as a risk factor for cerebrovascular disease (stroke and TIA) and myocardial infarction (MI) in a UK population cohort. A retrospective cohort of 106,601 HZ cases and 213,202 controls, matched for age, sex, and general practice, was identified from the THIN (The Health Improvement Network) general practice database. Cox proportional hazard models were used to examine the risks of stroke, TIA, and MI in cases and controls, adjusted for vascular risk factors, including body mass index >30 kg/m(2), smoking, cholesterol >6.2 mmol/L, hypertension, diabetes, ischemic heart disease, atrial fibrillation, intermittent arterial claudication, carotid stenosis, and valvular heart disease, over 24 (median 6.3) years after HZ infection. Risk factors for vascular disease were significantly increased in cases of HZ compared with controls. Adjusted hazard ratios for TIA and MI but not stroke were increased in all patients with HZ (adjusted hazard ratios [95% confidence intervals]: 1.15 [1.09-1.21] and 1.10 [1.05-1.16], respectively). However, stroke, TIA, and MI were increased in cases whose HZ occurred when they were younger than 40 years (adjusted hazard ratios [95% confidence intervals]: 1.74 [1.13-2.66], 2.42 [1.34-4.36], and 1.49 [1.04-2.15], respectively). Subjects younger than 40 years were significantly less likely to be asked about vascular risk factors compared with older patients (p TIA, and MI in subjects affected before the age of 40 years. In older subjects, better ascertainment of vascular risk factors and earlier intervention may explain the reduction in risk of stroke after HZ infection. © 2014 American Academy of Neurology.

    Full Text Available Abstract Background Research has indicated that general practitioners (GPs have good clinical judgment in regards to diagnosing and managing herpes zoster (HZ within clinical practice in a country with limited resources for primary care and general practice. The objective of the current study was to assess the burden of HZ and post herpetic neuralgia (PHN within rural general practices in Crete, Greece. Methods The current study took place within a rural setting in Crete, Greece during the period of November 2007 to November 2009 within the catchment area in which the Cretan Rural Practice-based Research Network is operating. In total 19 GP's from 14 health care units in rural Crete were invited to participate, covering a total turnover patient population of approximately 25, 000 subjects. For the purpose of this study an electronic record database was constructed and used as the main tool for monitoring HZ and PHN incidence. Stress related data was also collected with the use of the Short Anxiety Screening Test (SAST. Results The crude incidence rate of HZ was 1.4/1000 patients/year throughout the entire network of health centers and satellite practices, while among satellite practices alone it was calculated at 1.3/1000 patients/year. Additionally, the standardised incidence density within satellite practices was calculated at 1.6/1000 patients/year. In regards to the stress associated with HZ and PHN, the latter were found to have lower levels of anxiety, as assessed through the SAST score (17.4 ± 3.9 vs. 21.1 ± 5.7; p = 0.029. Conclusions The implementation of an electronic surveillance system was feasible so as to measure the burden of HZ and PHN within the rural general practice setting in Crete.

    General practitioners frequently encounter skin diseases and are accustomed to diagnosing the most common dermatologic conditions. We sought to determine the most common dermatologic topics published in five high-impact general medical journals (New England Journal of Medicine, The Lancet, the Journal of the American Medical Association, British Medical Journal (now The BMJ), and Annals of Internal Medicine). We conducted an independent search of the Thomson Reuters’ Science Citation Index for common dermatologic topics, limited to the period 1970 to 2012. Total number of publications dealing with each dermatologic topic considered. The five most common dermatologic topics published were melanoma, psoriasis, herpes simplex, herpes zoster, and acne. Melanoma and psoriasis were the top two dermatologic topics published in each journal except for Annals of Internal Medicine. Internists frequently diagnose herpes simplex, herpes zoster, and acne, which are also common dermatologic topics published. Although internists infrequently diagnose melanoma and psoriasis, they are major topics for general medical journals because of their increased community awareness, major advancements in therapeutic research, and their nondermatologic manifestations.

    To study corneal reinnervation and sensation recovery in Herpes zoster ophthalmicus (HZO). Two patients with HZO were studied over time with serial corneal esthesiometry and laser in vivo confocal microscopy (IVCM). A Boston keratoprosthesis type 1 was implanted, and the explanted corneal tissues were examined by immunofluorescence histochemistry for βIII-tubulin to stain for corneal nerves. The initial central corneal IVCM performed in each patient showed a complete lack of the subbasal nerve plexus, which was in accordance with severe loss of sensation (0 of 6 cm) measured by esthesiometry. When IVCM was repeated 2 years later before undergoing surgery, case 1 showed a persistent lack of central subbasal nerves and sensation (0 of 6). In contrast, case 2 showed regeneration of the central subbasal nerves (4786 μm/mm) with partial recovery of corneal sensation (2.5 of 6 cm). Immunostaining of the explanted corneal button in case 1 showed no corneal nerves, whereas case 2 showed central and peripheral corneal nerves. Eight months after surgery, IVCM was again repeated in the donor tissue around the Boston keratoprosthesis in both patients to study innervation of the corneal transplant. Case 1 showed no nerves, whereas case 2 showed new nerves growing from the periphery into the corneal graft. We demonstrate that regaining corneal innervation and corneal function are possible in patients with HZO as shown by corneal sensation, IVCM, and ex vivo immunostaining, indicating zoster neural damage is not always permanent and it may recover over an extended period of time.

Diagnostic vitreous biopsy of the right eye was performed to test for EBV and other known infectious causes of retinitis and evaluate vitreous cells and serological testing. Vitreous polymerase chain reaction viral DNA testing result was positive for EBV but negative for herpes simplex virus, varicella-zoster virus, and cytomegalovirus. Serologic testing was negative for toxoplasma gondii, syphilis, tuberculosis, and HIV. Histopathologic analysis of vitreous cells revealed atypical lymphocytes. Fluorescein angiography showed disk leakage, occluded retinal artery, peripheral vascular leakage, and ischemic area of the right eye. Intravenous acyclovir, 10 mg/kg/d, was prescribed for 14 days followed by oral acyclovir for 3 months. All lesions have become quiet. EBV may be a cause of retinal disease, and intravenous acyclovir is a successful treatment choice. Keywords: Epstein-Barr virus, retinal vasculitis, acyclovir, treatment

    Patients with multiple sclerosis (MS) frequently have an intrathecal production of antibodies to different common viruses, which can be detected by elevated antiviral antibody indices (AIs). There is a strong and consistent association of MS and Epstein-Barr virus (EBV) infection. To systematically compare the frequencies of intrathecal antibody production to EBV, measles virus, rubella virus, varicella zoster virus (VZV) and herpes simplex virus (HSV) in patients with MS. Review of the English and German literature on the frequencies of intrathecal immunoglobulin (Ig)G antibody production, as defined by an elevated AI, to EBV, measles virus, rubella virus, VZV and HSV in adult and pediatric patients with MS. In nine original studies identified, the frequencies of an intrathecal production of antibodies to Epstein-Barr nuclear antigen-1 (33/340, 9.7%), EBV viral capsid antigen (12/279, 4.3%) and antigens from EBV-infected cell lines (14/90, 15.6%) in adult patients with MS were clearly lower (p ≤ 0.03 for all pairwise comparisons) than the frequencies of an intrathecal production of antibodies to measles virus (612/922, 66.4%), rubella virus (521/922, 56.5%), VZV (470/922, 51%; data from 17 original studies) and HSV (78/291, 26.8%; data from 6 original studies). Though based on a lower number of original studies and patients, findings in children with MS were essentially similar. As in adults and children with MS the seroprevalence of EBV is higher than the seroprevalences of the other investigated viruses, the lower frequency of elevated EBV AIs became even more pronounced after correction of the frequencies of elevated antiviral AIs for the seroprevalences of the respective viruses. Given the very high seroprevalence of EBV in MS, the frequency of intrathecally produced antibodies to EBV in patients with MS is paradoxically low compared to that of other common viruses. These findings are compatible with the recently proposed hypothesis that in individuals

    A comparison of direct fluorescent-antibody assay (DFA), culture, and two PCR assays disclosed sensitivities of 87.8%, 46.3%, and 97.6% and 100%, respectively. We reviewed 1,150 results for clinical specimens submitted for DFA and culture and found that only 17 were culture positive/DFA negative. The incremental cost to detect these 17 positives was $3,078/specimen.

    Increasing life expectancy results in a larger proportion of older people susceptible to vaccine preventable diseases (VPDs). In the Netherlands, influenza vaccination is routinely offered to people aged 60 years and older. Vaccination against pneumococcal disease, herpes zoster and pertussis is rarely used. These vaccines will be evaluated by the Dutch Health Council and might be routinely offered to older people in the near future. Possible expansion of the program depends partly on the willingness of general practitioners (GPs) to endorse additional vaccinations. In this study, we assessed predictors of GPs' attitude and intention to vaccinate people aged 60 years and older. GPs (N = 12.194) were invited to fill in an online questionnaire consisting of questions about social cognitive factors that can influence the willingness of GPs to vaccinate people aged 60 years and older, including underlying beliefs, practical considerations of adding more vaccines to the national program, demographics, and GPs' patient population characteristics. The questionnaire was filled in by 732 GPs. GPs were positive both about vaccination as a preventive tool and the influenza vaccination program, but somewhat less positive about expanding the current program. Prediction analysis showed that the intention of GPs to offer additional vaccination was predicted by their attitude towards offering additional vaccination, towards vaccination as a preventive tool, towards offering vaccination during an outbreak and on GPs opinion regarding suitability to offer additional vaccination (R 2  = 0.60). The attitude of GPs towards offering additional vaccination was predicted by the perceived severity of herpes zoster and pneumonia, as well as the perceived incidence of herpes zoster. Severity of diseases was ranked as important argument to recommend vaccination, followed by effectiveness and health benefits of vaccines. Providing GPs with evidence-based information about the severity

  9. Virus-Vectored Influenza Virus Vaccines

    Despite the availability of an inactivated vaccine that has been licensed for >50 years, the influenza virus continues to cause morbidity and mortality worldwide. Constant evolution of circulating influenza virus strains and the emergence of new strains diminishes the effectiveness of annual vaccines that rely on a match with circulating influenza strains. Thus, there is a continued need for new, efficacious vaccines conferring cross-clade protection to avoid the need for biannual reformulation of seasonal influenza vaccines. Recombinant virus-vectored vaccines are an appealing alternative to classical inactivated vaccines because virus vectors enable native expression of influenza antigens, even from virulent influenza viruses, while expressed in the context of the vector that can improve immunogenicity. In addition, a vectored vaccine often enables delivery of the vaccine to sites of inductive immunity such as the respiratory tract enabling protection from influenza virus infection. Moreover, the ability to readily manipulate virus vectors to produce novel influenza vaccines may provide the quickest path toward a universal vaccine protecting against all influenza viruses. This review will discuss experimental virus-vectored vaccines for use in humans, comparing them to licensed vaccines and the hurdles faced for licensure of these next-generation influenza virus vaccines.

    A large number of viruses have been described in many different reptiles. These viruses include arboviruses that primarily infect mammals or birds as well as viruses that are specific for reptiles. Interest in arboviruses infecting reptiles has mainly focused on the role reptiles may play in the epidemiology of these viruses, especially over winter. Interest in reptile specific viruses has concentrated on both their importance for reptile medicine as well as virus taxonomy and evolution. The impact of many viral infections on reptile health is not known. Koch's postulates have only been fulfilled for a limited number of reptilian viruses. As diagnostic testing becomes more sensitive, multiple infections with various viruses and other infectious agents are also being detected. In most cases the interactions between these different agents are not known. This review provides an update on viruses described in reptiles, the animal species in which they have been detected, and what is known about their taxonomic positions.

    Astronauts experience symptomatic and asymptomatic herpes virus reactivation during spaceflight. We have shown increases in reactivation of Epstein-Barr virus (EBV), cytomegalovirus (CMV) and varicella zoster virus (VZV) and shedding in body fluids (saliva and urine) in astronauts during space travel. Alterations in immunity, increased stress hormone levels, microgravity, increased radiation, and other conditions unique to spaceflight may promote reactivation of latent herpes viruses. Unique mechanico-physico forces associated with spaceflight can have profound effects on cellular function, especially immune cells. In space flight analog studies such as Antarctica, bed rest studies, and NASA's undersea habitat (Aquarius), reactivation of these viruses occurred, but to a lesser extent than spaceflight. Spaceflight analogs model some spaceflight factors, but none of the analogs recreates all factors experienced in space. Most notably, microgravity and radiation are not included in many analogs. Stress, processed through the HPA axis and SAM systems, induces viral reactivation. However, the respective roles of microgravity and increased space radiation levels or if any synergy exists are not known. Therefore, we studied the effect of modeled space radiation and/or microgravity, independent of the immune system on the changes in cellular gene expression that results in viral (EBV) reactivation. The effects of modeled microgravity and low shear on EBV replication and cellular and EBV gene expression were studied in human B-lymphocyte cell cultures. Latently infected B-lymphocytes were propagated in the rotating wall bioreactor and irradiated with the various dosages of gamma irradiation. At specific time intervals following exposure to modeled microgravity, the cells and supernatant were harvested and reactivation of EBV were assessed by measuring EBV and gene expression, DNA methylation, and infectious virus production.

    Herpes zoster (HZ) has a significant negative effect on the productive work life of individuals, and has been shown to be responsible for cases of absenteeism, presenteeism and decreased work effectiveness. The aim of this study was to evaluate health utility scores and associated predictors in an actively employed population of Herpes Zoster (HZ) patients with and without work time loss (WTL). This was a pooled analysis of the prospective, observational MASTER cohort studies, conducted in 8 countries across North America, Latin America and Asia. A total of 428 HZ patients engaged in full or part time work were included. WTL, defined as missing ≥ 1 partial or full work day, and work effectiveness, reported on a scale of 0-100%, were evaluated with the Work and Productivity Questionnaire (WPQ). The Pearson product-moment correlation was used to assess the correlation between work effectiveness and HRQoL. Mixed models with repeated measures assessed the relationship between HZ-related WTL over a 6-month follow-up period, and HRQoL, as evaluated by the EQ-5D. Additional predictors of HRQoL were also identified. Overall, 57.7% of respondents reported WTL. Mean (SD) percent work effectiveness of patients in the WTL group was significantly lower compared to non-WTL (NWTL) patients at baseline [50.3 (31.6) vs. 71.4 (27.8); p work effectiveness was negatively associated with HRQoL overall (p work and productive life of actively employed individuals. In turn, HZ-related reductions in work effectiveness and work time are associated with a negative effect on HRQoL.

    This prospective, parallel-group, randomized, double-blind, multicenter study compared the efficacy and safety of FV-100 with valacyclovir for reducing pain associated with acute herpes zoster (HZ). Patients, ≥50 years of age, diagnosed with HZ within 72 h of lesion appearance who had HZ-associated pain, were randomized 1:1:1 to a 7-day course of either FV-100 200 mg QD (n = 117), FV-100 400 mg QD (n = 116), or valacyclovir 1000 mg TID (n =117). Efficacy was evaluated on the basis of the burden of illness (BOI; Zoster Brief Pain Inventory scores); incidence and duration of clinically significant pain (CSP); pain scores; incidence and severity of post-herpetic neuralgia (PHN); and times to full lesion crusting and to lesion healing. Safety was evaluated on the basis of adverse event (AE)/SAE profiles, changes in laboratory and vital signs values, and results of electrocardiograms. The burden of illness scores for pain through 30 days were 114.5, 110.3, and 118.0 for FV-100 200 mg, FV-100 400 mg, and valacyclovir 3000 mg, respectively. The incidences of PHN at 90 days for FV-100 200 mg, FV-100 400 mg, and valacyclovir 3000 mg were 17.8%, 12.4%, and 20.2%, respectively. Adverse event and SAE profiles of the two FV-100 and the valacyclovir groups were similar and no untoward signals or trends were evident. These results demonstrate a potential for FV-100 as an antiviral for the treatment of shingles that could both reduce the pain burden of the acute episode and reduce the incidence of PHN compared with available treatments. © 2016 Wiley Periodicals, Inc.

  15. Zika virus disease

    Full Text Available The Zika virus is an arbovirus belonging to the virus family Flaviviridae. The virus was isolated in 1947 from a rhesus monkey in the Zika Forest of Uganda. The virus causes sporadic mild human infections in Africa and later in Asia. However, by 2007 a major shift in its infection pattern was noticed and thousands of human infections were reported in the State of Yap and Federated States of Micronesia. In the last 3 years, major outbreaks have continued to occur and the virus has spread to several Pacific and American countries. These outbreaks were mostly asymptomatic; however, there were more severe clinical signs associated with the infections. Those signs included microcephaly and Guillain–Barre syndrome. It is believed that various species of mosquitoes can biologically transmit the virus. However, Aedes aegypti is most widely associated with the Zika virus. Recently, new modes of virus transmission have been reported, including mother-to-fetus, sexual, blood transfusion, animal bites, laboratory exposure and breast milk. Differential diagnosis is very important as some other arboviruses such as yellow fever virus, West Nile virus, dengue virus, and chikungunya virus have similar clinical manifestations to the Zika virus infection as well as relating serologically to some of these viruses. Established laboratory diagnostic tests to detect the Zika virus are limited, with reverse transcription polymerase chain reaction being the most widely used test. Taking into consideration the quickness of the spread of infection, size of the infected population and change of the infection severity pattern, the Zika virus infection merits collective efforts on all levels to prevent and control the disease. Limited research work and data, concurrent infection with other arboviruses, involvement of biological vectors, mass crowd events, human and trade movements and lack of vaccines are some of the challenges that we face in our efforts to prevent and

    Acute retinal necrosis (ARN), secondary to herpes simplex encephalitis, is a rare syndrome that can present in healthy individuals, as well as immuno-compromised patients. Most cases are caused by a secondary infection from the herpes virus family, with varicella zoster virus being the leading cause of this syndrome. Potential symptoms include blurry vision, floaters, ocular pain and photophobia. Ocular findings may consist of severe uveitis, retinal vasculitis, retinal necrosis, papillitis and retinal detachment. Clinical manifestations of this disease may include increased intraocular pressure, optic disc oedema, optic neuropathy and sheathed retinal arterioles. A complete work up is essential to rule out cytomegalovirus retinitis, herpes simplex encephalitis, herpes virus, syphilis, posterior uveitis and other conditions. Depending on the severity of the disease, the treatment options consist of anticoagulation therapy, cycloplegia, intravenous acyclovir, systemic steroids, prophylactic laser photocoagulation and pars plana vitrectomy with silicon oil for retinal detachment. An extensive history and clinical examination is crucial in making the correct diagnosis. Also, it is very important to be aware of low vision needs and refer the patients, if expressing any sort of functional issues with completing daily living skills, especially reading. In this article, we report one case of unilateral ARN 20 years after herpetic encephalitis. © 2016 Optometry Australia.

    Laboratory diagnosis of molluscum contagiosum virus (MCV) is important as lesions can be confused with those caused by Cryptococcus neoformans, herpes simplex virus, human papillomavirus, and varicella-zoster virus. To develop a rapid method for identifying patients infected with MCV via swab sampling. Two dual-labeled probe real-time PCR assays, one homologous to the p43K gene and one to the MC080R gene, were designed. The p43K PCR was designed to be used in conjunction with Pyrosequencing for confirmation of PCR products and discrimination between MCV1 and MCV2. Both PCR assays were optimized with respect to reaction components, thermocycling parameters, and primer and probe concentrations. The specificities of both PCR assays were confirmed by non-amplification of 38 known human pathogens. Sensitivity assays demonstrated detection of as few as 10 copies per reaction. Testing 703 swabs, concordance between the two real-time PCR assays was 99.9%. Under the developed conditions, Pyrosequencing of the p43K PCR product was capable of providing enough nucleotide sequence to definitively differentiate MCV1 and MCV2. These real-time PCR assays can be used for the rapid, sensitive, and specific detection of MCV and, when combined with Pyrosequencing, can further discriminate between MCV1 and MCV2.

    Viruses are the accepted cause of many important cancers including cancers of the cervix and anogenital area, the liver, some lymphomas, head and neck cancers and indirectly human immunodeficiency virus associated cancers. For over 50 years, there have been serious attempts to identify viruses which may have a role in breast cancer. Despite these efforts, the establishment of conclusive evidence for such a role has been elusive. However, the development of extremely sophisticated new experimental techniques has allowed the recent development of evidence that human papilloma virus, Epstein-Barr virus, mouse mammary tumor virus and bovine leukemia virus may each have a role in the causation of human breast cancers. This is potentially good news as effective vaccines are already available to prevent infections from carcinogenic strains of human papilloma virus, which causes cancer of the uterine cervix.

  12. Nairobi sheep disease virus/Ganjam virus.

    Science.gov (United States)

    M D, Baron; B, Holzer

    2015-08-01

    Nairobi sheep disease virus (NSDV) is a tick-borne virus which causes a severe disease in sheep and goats, and has been responsible for several outbreaks of disease in East Africa. The virus is also found in the Indian subcontinent, where it is known as Ganjam virus. The virus only spreads through the feeding of competent infected ticks, and is therefore limited in its geographic distribution by the distribution of those ticks, Rhipicephalus appendiculata in Africa and Haemaphysalis intermedia in India. Animals bred in endemic areas do not normally develop disease, and the impact is therefore primarily on animals being moved for trade or breeding purposes. The disease caused by NSDV has similarities to several other ruminant diseases, and laboratory diagnosis is necessary for confirmation. There are published methods for diagnosis based on polymerase chain reaction, for virus growth in cell culture and for other simple diagnostic tests, though none has been commercialised. There is no established vaccine against NSDV, although cell-culture attenuated strains have been developed which show promise and could be put into field trials if it were deemed necessary. The virus is closely related to Crimean-Congo haemorrhagic fever virus, and studies on NSDV may therefore be useful in understanding this important human pathogen.

Over half a century, nine virus species belonging to the genera Ilarvirus, Cucumovirus, Nepovirus, Tobamovirus, Potexvirus, and Potyvirus have been found in this crop. The potyvirus Asparagus virus 1 (AV1) and the ilarvirus Asparagus virus 2 (AV2) are widespread and negatively affect the economic life of asparagus crops reducing yield and increasing the susceptibility to biotic and abiotic stress. The main properties and epidemiology of AV1 and AV2 as well as diagnostic techniques for their detection and identification are described. Minor viruses and control are briefly outlined.

    Full Text Available An unprecedented number of Ebola virus infections among healthcare workers and patients have raised questions about our understanding of Ebola virus transmission. Here, we explore different routes of Ebola virus transmission between people, summarizing the known epidemiological and experimental data. From this data, we expose important gaps in Ebola virus research pertinent to outbreak situations. We further propose experiments and methods of data collection that will enable scientists to fill these voids in our knowledge about the transmission of Ebola virus.

    The use of protoplasts in the study of plant viruses has attracted considerable attention since its inception in the late 1960s. This article is an attempt to assess the current status of protoplasts (primarily) and all cell cultures (in some instances) in studies of virus infection, virus replication, cytopathology, cross-protection, virus resistance, and the use of in vitro methods and genetic engineering to recover virus-resistant plants. These areas of study proved difficult to do entirely with whole plants or plant parts. However, because protoplasts could be synchronously infected with virus, they provided a valuable alternative means of following biochemical and cytological events in relation to the virus growth cycle in a more precise manner than previously possible

    To evaluate the risks of herpes zoster (HZ) and herpes simplex virus (HSV) infection associated with tofacitinib compared with biologic agents among patients with rheumatoid arthritis (RA). Using health plan data from 2010 to 2014, patients with RA initiating tofacitinib or biologics with no history of HZ or HSV were identified, as were incident cases of HZ or HSV. Crude incidence rates were calculated by drug exposure. Cox proportional hazards models evaluated the adjusted association between tofacitinib and HZ, and a composite outcome of HZ or HSV. A total of 2526 patients initiating tofacitinib were compared with initiations of other biologics: anti-tumour necrosis factor (TNF) (n=42 850), abatacept (n=12 305), rituximab (n=5078) and tocilizumab (n=6967). Patients receiving tofacitinib were somewhat younger (mean age 55 years) versus those on other biologics, and somewhat less likely to use concomitant methotrexate (MTX) (39% vs 43%-56%, depending on drug). Crude incidence of HZ associated with tofacitinib was 3.87/100 patient-years (py). After multivariable adjustment, HZ risk was significantly elevated, HR 2.01 (95% CI 1.40 to 2.88) compared with abatacept. Rates and adjusted HRs for all other RA biologics were comparable with each other and abatacept. Older age, female sex, prednisone >7.5 mg/day, prior outpatient infection and greater number of hospitalisations were also associated with increased HZ risk. Incidence rates for the combined outcome were greatest for tofacitinib (7.61/100 py) and also significantly elevated after adjustment (HR=1.40, 95% CI 1.09 to 1.81). The rate of zoster associated with tofacitinib was approximately double that observed in patients using biologics. Published by the BMJ Publishing Group Limited.

    Each year in France, varicella and zoster affect large numbers of children and adults, resulting in medical visits, hospitalizations for varicella- and zoster-related complications, and societal costs. Disease prevention by varicella vaccination is feasible, wherein a plausible option involves replacing the combined measles, mumps, and rubella (MMR) vaccine with the combined MMR and varicella (MMRV) vaccine. This study aimed to: (1) assess the cost-effectiveness of adding routine varicella vaccination through MMRV, using different vaccination strategies in France; and (2) address key uncertainties, such as the economic consequences of breakthrough varicella cases, the waning of vaccine-conferred protection, vaccination coverage, and indirect costs. Based on the outputs of a dynamic transmission model that used data on epidemiology and costs from France, a cost-effectiveness model was built. A conservative approach was taken regarding the impact of varicella vaccination on zoster incidence by assuming the validity of the hypothesis of an age-specific boosting of immunity against varicella. The model determined that routine MMRV vaccination is expected to be a cost-effective option, considering a cost-effectiveness threshold of €20,000 per quality-adjusted life-year saved; routine vaccination was cost-saving from the societal perspective. Results were driven by a large decrease in varicella incidence despite a temporary initial increase in the number of zoster cases due to the assumption of exogenous boosting. In the scenario analyses, despite moderate changes in assumptions about incidence and costs, varicella vaccination remained a cost-effective option for France. Routine vaccination with MMRV was associated with high gains in quality-adjusted life-years, substantial reduction in the occurrences of varicella- and zoster-related complications, and few deaths due to varicella. Routine MMRV vaccination is also expected to provide reductions in costs related to

    Viruses have been considered for a long time as by-products of biological evolution. This view is changing now as a result of several recent discoveries. Viral ecologists have shown that viral particles are the most abundant biological entities on our planet, whereas metagenomic analyses have revealed an unexpected abundance and diversity of viral genes in the biosphere. Comparative genomics have highlighted the uniqueness of viral sequences, in contradiction with the traditional view of viruses as pickpockets of cellular genes. On the contrary, cellular genomes, especially eukaryotic ones, turned out to be full of genes derived from viruses or related elements (plasmids, transposons, retroelements and so on). The discovery of unusual viruses infecting archaea has shown that the viral world is much more diverse than previously thought, ruining the traditional dichotomy between bacteriophages and viruses. Finally, the discovery of giant viruses has blurred the traditional image of viruses as small entities. Furthermore, essential clues on virus history have been obtained in the last ten years. In particular, structural analyses of capsid proteins have uncovered deeply rooted homologies between viruses infecting different cellular domains, suggesting that viruses originated before the last universal common ancestor (LUCA). These studies have shown that several lineages of viruses originated independently, i.e., viruses are polyphyletic. From the time of LUCA, viruses have coevolved with their hosts, and viral lineages can be viewed as lianas wrapping around the trunk, branches and leaves of the tree of life. Although viruses are very diverse, with genomes encoding from one to more than one thousand proteins, they can all be simply defined as organisms producing virions. Virions themselves can be defined as infectious particles made of at least one protein associated with the viral nucleic acid, endowed with the capability to protect the viral genome and ensure its

    We designed, optimized, and extensively tested several sensitive and specific real-time PCR assays for rapid detection of both smallpox and pan-orthopox virus DNAs. The assays are based on TaqMan 3'-minor groove binder chemistry and were performed on both the rapid-cycling Roche LightCycler and the Cepheid Smart Cycler platforms. The hemagglutinin (HA) J7R, B9R, and B10R genes were used as targets for the variola virus-specific assays, and the HA and DNA polymerase-E9L genes were used as targets for the pan-orthopox virus assays. The five orthopox virus assays were tested against a panel of orthopox virus DNAs (both genomic and cloned) at the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID). The results indicated that each assay was capable of detecting both the appropriate cloned gene and genomic DNA. The assays showed no cross-reactivity to the 78 DNAs in the USAMRIID bacterial cross-reactivity panel. The limit of detection (LOD) of each assay was determined to be between 12 and 25 copies of target DNA. The assays were also run against a blind panel of DNAs at the Centers for Disease Control and Prevention (CDC) on both the LightCycler and the Smart Cycler. The panel consisted of eight different variola virus isolates, five non-variola virus orthopox virus isolates, two varicella-zoster virus isolates, and one herpes simplex virus isolate. Each sample was tested in triplicate at 2.5 ng, 25 pg, 250 fg, and 2.5 fg, which represent 1.24 x 10(7), 1.24 x 10(5), 1.24 x 10(3), and 1.24 x 10(1) genome equivalents, respectively. The results indicated that each of the five assays was 100% specific (no false positives) when tested against both the USAMRIID panels and the CDC blind panel. With the CDC blind panel, the LightCycler was capable of detecting 96.2% of the orthopox virus DNAs and 93.8% of the variola virus DNAs. The Smart Cycler was capable of detecting 92.3% of the orthopox virus DNAs and between 75 and 93.8% of the variola virus DNAs

    2017-01-01

    Budding yeast (Saccharomyces cerevisiae) and fission yeast (Schizosaccharomyces pombe) are two popular model organisms for virus research. They are natural hosts for viruses as they carry their own indigenous viruses. Both yeasts have been used for studies of plant, animal and human viruses. Many positive sense (+) RNA viruses and some DNA viruses replicate with various levels in yeasts, thus allowing study of those viral activities during viral life cycle. Yeasts are single cell eukaryotic organisms. Hence, many of the fundamental cellular functions such as cell cycle regulation or programed cell death are highly conserved from yeasts to higher eukaryotes. Therefore, they are particularly suited to study the impact of those viral activities on related cellular activities during virus-host interactions. Yeasts present many unique advantages in virus research over high eukaryotes. Yeast cells are easy to maintain in the laboratory with relative short doubling time. They are non-biohazardous, genetically amendable with small genomes that permit genome-wide analysis of virologic and cellular functions. In this review, similarities and differences of these two yeasts are described. Studies of virologic activities such as viral translation, viral replication and genome-wide study of virus-cell interactions in yeasts are highlighted. Impacts of viral proteins on basic cellular functions such as cell cycle regulation and programed cell death are discussed. Potential applications of using yeasts as hosts to carry out functional analysis of small viral genome and to develop high throughput drug screening platform for the discovery of antiviral drugs are presented.

    Although a wide range of viruses have been reported in marine molluscs, most of these reports rely on ultrastructural examination and few of these viruses have been fully characterized. The lack of marine mollusc cell lines restricts virus isolation capacities and subsequent characterization works. Our current knowledge is mostly restricted to viruses affecting farmed species such as oysters Crassostrea gigas, abalone Haliotis diversicolor supertexta or the scallop Chlamys farreri. Molecular approaches which are needed to identify virus affiliation have been carried out for a small number of viruses, most of them belonging to the Herpesviridae and birnaviridae families. These last years, the use of New Generation Sequencing approach has allowed increasing the number of sequenced viral genomes and has improved our capacity to investigate the diversity of viruses infecting marine molluscs. This new information has in turn allowed designing more efficient diagnostic tools. Moreover, the development of experimental infection protocols has answered some questions regarding the pathogenesis of these viruses and their interactions with their hosts. Control and management of viral diseases in molluscs mostly involve active surveillance, implementation of effective bio security measures and development of breeding programs. However factors triggering pathogen development and the life cycle and status of the viruses outside their mollusc hosts still need further investigations. Copyright © 2017 Elsevier Inc.

    Full Text Available Purpose: To standardize and apply a polymerase chain reaction (PCR on the glycoprotein D gene to differentiate Herpes simplex virus (HSV 1 & 2 serotypes in culture negative intraocular specimens. Methods: Twenty-one intraocular fluids collected from 19 patients were subjected to cultures for HSV and uniplex PCR (uPCR for DNA polymerase gene. To differentiate HSV serotypes, as 1 & 2, a seminested PCR (snPCR targeting the glycoprotein D gene was standardised and applied onto 21 intraocular fluids. The specificity of the snPCR was verified by application onto ATCC strains of HSV 1 and 2, clinical isolates and DNA sequencing of the amplified products. All specimens were also tested for the presence of cytomegalovirus (CMV and varicella zoster virus (VZV by nucleic acid amplification methods. Results: Four of the 21 intraocular fluids were positive for HSV by uPCR. snPCR detected HSV in three additional specimens (total of seven specimens, and identified three as HSV 1 and four as HSV 2. DNA sequencing of PCR products showed 100% homology with the standard strains of HSV 1 and 2 respectively. None of the samples were positive in culture. Among the other patients, CMV DNA was detected in two and VZV DNA in five others. Conclusions: The standardized snPCR can be applied directly onto the culture negative specimens for rapid differentiation of HSV serotypes.

    1997-12-01

    Necrotizing herpetic retinopathies (NHR), a new spectrum of diseases induced by viruses of the herpes family (herpes simplex virus, varicella-zoster virus and cytomegalovirus), includes acute retinal necrosis (ARN) occurring in apparently immunocompetent patients and progressive outer retinal necrosis (PORN) described in severely immuno-compromised patients. Signs of impaired cellular immunity were seen in 16% of ARN patients in a review of 216 reported cases, indicating that immune dysfunction is not only at the origin of PORN but might also be at the origin of ARN. The aim of this study was to correlate clinical findings in NHR patients with their immunologic parameters. Charts from patients with the diagnosis of ARN or PORN seen from 1990 to 1995 were reviewed. Clinical characteristics and disease patterns were correlated with immunological parameters taking into account CD4 lymphocyte rate in AIDS patients and blood-lymphocyte subpopulation determination by flow cytometry, cutaneous delayed type hypersensitivity testing and lymphocytic proliferation rate to seven antigens in HIV-negative patients. During the period considered, 11 patients and 7 patients fulfilled the criteria of ARN and PORN respectively. Immune dysfunctions were identified in most patients. Mild type of ARN and classical ARN were associated with discrete immune dysfunctions, ARN with features of PORN was seen in more immunodepressed patients and classical PORN was always seen in severely immunodepressed HIV patients. Our findings suggest that NHR is a continuous spectrum of diseases induced by herpes viruses, whose clinical expression depends on the immune state of the host going from mild or classical ARN at one end in patients with non-detectable or slight immune dysfunction to PORN in severely immunodepressed patients at the other end and with intermediary forms between these extremes.

    2011-09-21

    The etiology of reptilian viral diseases can be attributed to a wide range of viruses occurring across different genera and families. Thirty to forty years ago, studies of viruses in reptiles focused mainly on the zoonotic potential of arboviruses in reptiles and much effort went into surveys and challenge trials of a range of reptiles with eastern and western equine encephalitis as well as Japanese encephalitis viruses. In the past decade, outbreaks of infection with West Nile virus in human populations and in farmed alligators in the USA has seen the research emphasis placed on the issue of reptiles, particularly crocodiles and alligators, being susceptible to, and reservoirs for, this serious zoonotic disease. Although there are many recognised reptilian viruses, the evidence for those being primary pathogens is relatively limited. Transmission studies establishing pathogenicity and cofactors are likewise scarce, possibly due to the relatively low commercial importance of reptiles, difficulties with the availability of animals and permits for statistically sound experiments, difficulties with housing of reptiles in an experimental setting or the inability to propagate some viruses in cell culture to sufficient titres for transmission studies. Viruses as causes of direct loss of threatened species, such as the chelonid fibropapilloma associated herpesvirus and ranaviruses in farmed and wild tortoises and turtles, have re-focused attention back to the characterisation of the viruses as well as diagnosis and pathogenesis in the host itself.

  9. Strategy as a Virus

    DEFF Research Database (Denmark)

    Obed Madsen, Søren

    This article is based on virus theory (Røvik, 2007, 2011), and proposes to develop a framework that defines technology as a virus that penetrates the organism of an organization. The framework develops a new vocabulary, which can help in analyzing technologies and their negative effects on actors...... and organizations. In this paper, the virus theory is used to analyze a strategy process in an organization as an example of a technology. It shows how the strategy over time creates a memory loss, where the managers who are exposed to the virus forget their critique of the new strategy concept. The article also...... shows how resistant can be understood as being immune to a virus, since the strategy concepts bears resemblance to a former strategy concept. The article also argues that there should be more focus on the negative impacts of management tool and especially how organizations and managers are dealing...

    A new class of chemical inhibitors has been discovered that interferes with the process of herpesvirus DNA replication. To date, the majority of useful herpesvirus antivirals are nucleoside analogues that block herpesvirus DNA replication by targeting the DNA polymerase. The new helicase-primase inhibitors (HPI) target a different enzyme complex that is also essential for herpesvirus DNA replication. This review will place the HPI in the context of previous work on the nucleoside analogues. Several promising highly potent HPI will be described with a particular focus on the identification of drug-resistance mutations. Several HPI have good pharmacological profiles and are now at the outset of phase II clinical trials. Provided there are no safety issues to stop their progress, this new class of compound will be a major advance in the herpesvirus antiviral field. Furthermore, HPI are likely to have a major impact on the therapy and prevention of herpes simplex virus and varicella zoster in both immunocompetent and immunocompromised patients alone or in combination with current nucleoside analogues. The possibility of acquired drug-resistance to HPI will then become an issue of great practical importance. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Cerebrospinal fluid (CSF) specimens from 27 patients with encephalitis, meningitis, and other neurological diseases were studied for the presence of herpes simplex virus types 1 and 2 (HSV-1/-2), varicella-zoster virus (VZV), cytomegalovirus (CMV), human herpesviruses 6A and 6B (HHV-6A/-6B) and Epstein-Barr virus (EBV) DNA using the polymerase chain reaction (PCR) method. The DNAs were amplified using two sets of consensus primer pairs in a single tube, bringing simultaneous amplification of the herpesviruses. The PCR products were analyzed by agarose gel electrophoresis, and Southern blot hybridization with virus-type specific probes, thus allowing discrimination between the different types of herpesviruses to be made. Each virus-specific probe was highly specific for identifying the PCR product. Thirty CSF specimens from 13 patients with encephalitis and 10 specimens from 10 patients with meningitis, respectively, were examined using this method. Eight patients with encephalitis and six with meningitis were positive for different herpesviruses, including patients with coinfections (HSV-1/-2 and VZV, VZV and CMV). Among four CSF specimens from four patients with other neurological disorders, dual amplification of CMV and EBV was present. Since identification of the types of herpesviruses in this system requires a very small amount of CSF, and is completed with one PCR, it is useful for routine diagnosis of herpesvirus infections in diagnostic laboratories. The viruses responsible for central nervous system infection are easily detected with various coinfection and serial patterns of herpesviruses, by this consensus primer-based PCR method. This may give an insight into the relationship between virus-related neurological diseases (VRNDS) and herpesvirus infections.

    Zika virus belongs to the family of Flaviviridae. The Flaviviridae family also includes other human pathogens like West Nile virus (WNV), Yellow fever virus (YFV), mosquito transmitted Dengue virus (DENV), Tick borne encephalitic virus (TBEV) and Japanese encephalitis virus (JEV). Zika virus is a mosquito-borne disease and is transmitted by Aedes aegypti mosquito.

    A description is presented of a radioimmunoassay designed to prove the presence of the antibody against the hepatitis A virus (HA Ab, anti-Ha) using an Abbott HAVAB set. This proof as well as the proof of the antibody against the nucleus of the hepatitis B virus is based on competition between a normal antibody against hepatitis A virus and a 125 I-labelled antibody for the binding sites of a specific antigen spread all over the surface of a tiny ball; this is then indirect proof of the antibody under investigation. The method is described of reading the results from the number of impulses per 60 seconds: the higher the titre of the antibody against the hepatitis A virus in the serum examined, the lower the activity of the specimen concerned. The rate is reported of incidence of the antibody against the hepatitis A virus in a total of 68 convalescents after hepatitis A; the antibody was found in 94.1%. The immunoglobulin made from the convalescents' plasma showed the presence of antibodies in dilutions as high as 1:250 000 while the comparable ratio for normal immunoglobulin Norga was only 1:2500. Differences are discussed in the time incidence of the antibodies against the hepatitis A virus, the antibodies against the surface antigen of hepatitis B, and the antibody against the nucleus of the hepatitis V virus.

    2013-01-01

    SUMMARY Respiratory viruses (including adenovirus, influenza virus, respiratory syncytial virus, coronavirus, and rhinovirus) cause a broad spectrum of disease in humans, ranging from mild influenza-like symptoms to acute respiratory failure. While species D adenoviruses and subtype H7 influenza viruses are known to possess an ocular tropism, documented human ocular disease has been reported following infection with all principal respiratory viruses. In this review, we describe the anatomical proximity and cellular receptor distribution between ocular and respiratory tissues. All major respiratory viruses and their association with human ocular disease are discussed. Research utilizing in vitro and in vivo models to study the ability of respiratory viruses to use the eye as a portal of entry as well as a primary site of virus replication is highlighted. Identification of shared receptor-binding preferences, host responses, and laboratory modeling protocols among these viruses provides a needed bridge between clinical and laboratory studies of virus tropism.

    of the worldwide distribution of the disease will be given. Virus evolution: Recent studies indicate that only a few amino acid changes in the structural proteins of VHSV can change the virulence patterns significantly, thereby coming closer to assessing the risk of none to low virulent viruses becoming high...... virulent. Virulence factors both depend on the ability of VHSV to enter a cell and on the speed and efficiencyof virus replication in the cells. Apparently the viral nucleocapsid protein plays a very important role for the later and seems to be the target for determination of a virulence marker....

  20. Viruses in reptiles

    Full Text Available Abstract The etiology of reptilian viral diseases can be attributed to a wide range of viruses occurring across different genera and families. Thirty to forty years ago, studies of viruses in reptiles focused mainly on the zoonotic potential of arboviruses in reptiles and much effort went into surveys and challenge trials of a range of reptiles with eastern and western equine encephalitis as well as Japanese encephalitis viruses. In the past decade, outbreaks of infection with West Nile virus in human populations and in farmed alligators in the USA has seen the research emphasis placed on the issue of reptiles, particularly crocodiles and alligators, being susceptible to, and reservoirs for, this serious zoonotic disease. Although there are many recognised reptilian viruses, the evidence for those being primary pathogens is relatively limited. Transmission studies establishing pathogenicity and cofactors are likewise scarce, possibly due to the relatively low commercial importance of reptiles, difficulties with the availability of animals and permits for statistically sound experiments, difficulties with housing of reptiles in an experimental setting or the inability to propagate some viruses in cell culture to sufficient titres for transmission studies. Viruses as causes of direct loss of threatened species, such as the chelonid fibropapilloma associated herpesvirus and ranaviruses in farmed and wild tortoises and turtles, have re-focused attention back to the characterisation of the viruses as well as diagnosis and pathogenesis in the host itself. 1.
