BACKGROUND: In immunocompromised patients, primary infection with VZV may have a disastrous clinical course. Vaccination of VZV-seronegative patients on the waiting list for renal transplantation may prevent severe disease. However, the immunologic response of end-stage renal disease patients to peptide vaccines is far from optimal. Our question was whether end-stage renal disease patients with undetectable VZV-IgG levels were able to mount an adequate humoral and cellular response to a live attenuated varicella vaccine...

BACKGROUND: Varicella is a common infectious disease primarily of childhood that is usually benign and self-limited. It is, however, increasingly seen in adults who are at a higher risk of severe infection. Ocular complications of varicella are relatively uncommon and have been rarely described in adults. We describe herein five adults who developed ocular involvement in association with primary varicella-zoster virus infection. FINDINGS: Ocular manifestations included acute anterior uveitis in four eyes, with associated stromal keratitis in one of them, epithelial ulcerative keratitis in the two eyes of one patient, and acute retinal necrosis in one eye...

To identify risk factors for varicella zoster virus (VZV) infection and postherpetic neuralgia (PHN) after hematopoietic cell transplantation (HCT), we conducted a retrospective chart review of 163 consecutive patients who underwent HCT between November 2004 and July 2014. Overall, the male/female (M/F) ratio was 80/83, median age at HCT was 54 (range 15-69) years, and autologous/allogeneic HCT (auto/allo-HCT) ratio was 71/92. Forty-four patients [M/F, 25/19; median age, 57 (range: 16-68) years; auto/allo-HCT, 26/18] developed VZV infection after HCT...

Vaccine-preventable diseases such as measles, mumps, rubella, and varicella continue to plague children and adults worldwide. Although public health programs have helped decrease the prevalence and sequelae of these diseases, outbreaks still occur. To limit the spread of these diseases, emergency clinicians must be able to readily identify the characteristic presentations of the rashes associated with measles, rubella, and varicella, as well as the common presenting features associated with mumps. Diagnostic laboratory studies are not usually necessary, as a complete history and physical examination usually lead to an accurate diagnosis...

REVIEW
Eliza F Chakravarty
Herpes zoster is the reactivation of latent varicella zoster virus usually occurring decades after initial exposure, and manifesting as a painful vesicular rash occurring along one or more dermatomes. Zoster incidence increases with age as cell mediated immunity against latent virus wanes. Epidemiological evidence suggests that individuals with underlying rheumatic diseases are at increased risk for zoster. It remains unclear whether this is due to immunosuppressive medications or from immune dysregulation of the underlying disease...

Varicella zoster virus (VZV) is a human neurotropic alphaherpesvirus that causes chickenpox (varicella) in children. VZV reactivation may lead to neurological complications, including transverse myelitis. However, transverse myelitis caused by VZV reactivation is rare in immunocompetent patients. Herein, we report a case of transverse myelitis caused by VZV in an immunocompetent older patient, and confirmed this case by polymerase chain reaction. A 79-year-old woman visited our service with complaints of weakness in the right lower leg, generalized vesicular eruptions, and throbbing pain in the right flank for ten days...

BACKGROUND: 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. METHODS: 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...

Jane Hecht, Anette Siedler
BACKGROUND: Since 2004 a single varicella vaccination for all infants aged 11-14 months has been recommended in Germany and since 2009 a second dose at the age of 15-23 months is recommended. Vaccination coverage after 24 months rose from 43% in 2006 to 87.5% in 2012. A mandatory notification system was introduced in the New Federal States (NFS) between 2002 and 2009 and nationwide in 2013. A national sentinel system has been in place since 2005. OBJECTIVE AND METHOD: We analyzed both data sources to describe the varicella epidemiology related to vaccination coverage after initiation of routine childhood varicella vaccination and to evaluate both notification systems regarding informative value and data quality...

The seasonality and periodicity of infections, and the mechanisms underlying observed dynamics, can have implications for control efforts. This is particularly true for acute childhood infections. Among these, the dynamics of measles is the best understood and has been extensively studied, most notably in the UK prior to the start of vaccination. Less is known about the dynamics of other childhood diseases, particularly outside Europe and the United States. In this paper, we leverage a unique dataset to examine the epidemiology of six childhood infections - measles, mumps, rubella, varicella, scarlet fever and pertussis - across 32 states in Mexico from 1985 to 2007...

A woman presented with at least four manifestations of varicella-zoster virus (VZV) infection, including central nervous system vasculitis, during her first 2 years of HIV infection. We evaluated her CD4 T cell responses to VZV given the infrequency with which multiple recurrences of VZV occurred, especially following immune reconstitution on antiretroviral therapy.

BACKGROUND: There is little evidence about either prevention or treatment of childhood arterial ischaemic stroke (AIS). However, drugs that regulate the immune and inflammatory response could theoretically prevent occurrence or recurrence of AIS. Additionally, as an acute treatment, they may limit the neurological damage caused by AIS. Here, we systematically review the evidence on the use of immunotherapy in childhood AIS. DESIGN: A systematic review of publications in databases Embase and Medline from inception...

BACKGROUND: The autologous hematopoietic stem cell transplantation procedure involves immunosuppression of the patient. Thus, the patient has an elevated risk for several diseases, such as infections with the varicella-zoster virus. Prevention protocols have been proposed based on the use of acyclovir from the first day of conditioning, and maintaining this drug for 30-100 days after the procedure or for as much as one year. The objective of this work was to evaluate the incidence of herpes zoster after autologous transplantations related to the early suspension of acyclovir...

AIM: Data about immunisation rates in cystic fibrosis (CF) patients are scarce. We estimated the rates and timeliness of immunisations in CF patients aged 0.55-22 years. METHODS: We studied 122 subjects at a hospital in Greece in 2014. A standard questionnaire was used to collect data and parents' opinions about immunisations. RESULTS: The complete immunisation rates were 92.6% for diphtheria-tetanus-acellular pertussis-inactivated poliomyelitis-Haemophilus influenzae (DTaP-IPV-Hib), 96...

BACKGROUND: Varicella is an acute infectious disease common during childhood. It has mostly an uncomplicated course in early childhood. Neverthless, it may result in severe complications, especially in particular age groups and clinical conditions. Down Syndrome represents a risk factor for developing complications, because of the frequent comorbidities and their immunodeficiency. CASE PRESENTATION: A 2-year-old white Caucasian female affected by Down Syndrome was referred to our hospital for cardiac arrest in course of varicella disease...

The BioPlex 2200 (Bio-Rad Laboratories, Hercules, Ca) is a rapid, automated platform, which can screen large numbers of specimens for antibodies to measles, mumps, rubella and varicella. Although approved for producing qualitative results, in this study we have validated the test (off-label) to allow reporting of quantitative results. To do this, we used the 3(rd) anti-measles WHO standard to generate a calibration curve that allowed relative fluorescence intensity to be translated into quantitative antibody titer (Antibody Units/mL (AU/mL))...

We report the clinical course and outcome of primary varicella infection in six children with systemic juvenile idiopathic arthritis (sJIA) receiving tocilizumab. None had disseminated or fatal varicella infection, but one patient developed macrophage activation syndrome (MAS) and another had an arthritis relapse. All patients had a significant elevation of serum IL-6 levels, and the two children who developed MAS or arthritis relapse showed high serum IL-18 levels, which could cause a sJIA flare-up.

A previously healthy 2-year-old girl, vaccinated for varicella at 17 months, was admitted because of left-sided facial herpes zoster caused by vaccine-strain varicella-zoster virus (VZV). She recovered fully with no complication after intravenous treatment using acyclovir. Earlier reports have described that herpes zoster (HZ) rashes caused by vaccine-strain VZV tend to occur on the dermis corresponding to the skin area where the varicella vaccine was received. However, rashes appeared on this girl only in the trigeminal nerve area, which is unrelated to the vaccinated site...
