School, child care and camp exclusion policies for chickenpox: A rational approach.

Paediatr Child Health 2018 Sep 16;23(6):420-427. Epub 2018 Aug 16.

Canadian Paediatric Society, Infectious Diseases and Immunization Committee, Ottawa, Ontario.

Widespread varicella vaccination in Canada since 2007 has changed the epidemiology of chickenpox, with a significant decline in varicella-related hospitalizations. However, there will always be a varicella-susceptible population because of immune-compromising treatments or conditions and/or parental vaccine refusal. This document updates and replaces a 1999 statement by the Canadian Paediatric Society. Read More

BMC Infect Dis 2019 Feb 7;19(1):127. Epub 2019 Feb 7.

University Hospital for Infectious Diseases "Dr. Fran Mihaljević", Mirogojska 8, 10000, Zagreb, Croatia.

Background: Tumor necrosis factor-α (TNF-α) antagonists, most of which are monoclonal antibodies, became a widespread treatment for autoimmune diseases such as rheumatoid arthritis, ankylosing spondylitis, inflammatory bowel diseases, psoriasis, psoriatic arthritis, hidradenitis suppurativa and uveitis. Their use is based on the blockage of TNF-α, which plays an important role in granulomas formation, development of phagosomes, activation and differentiation of macrophages, immune response against viral pathogens. The multiple adverse effects of TNF-α inhibition have been identified, including a two-to four-fold increased risk of active tuberculosis and other granulomatous conditions and an increased occurrence of some other serious bacterial, fungal and certain viral infections.

Recognition of aerosol transmission of infectious agents: a commentary.

BMC Infect Dis 2019 Jan 31;19(1):101. Epub 2019 Jan 31.

Department of Infection, Immunity and Inflammation, University of Leicester, Leicester, UK.

Although short-range large-droplet transmission is possible for most respiratory infectious agents, deciding on whether the same agent is also airborne has a potentially huge impact on the types (and costs) of infection control interventions that are required.The concept and definition of aerosols is also discussed, as is the concept of large droplet transmission, and airborne transmission which is meant by most authors to be synonymous with aerosol transmission, although some use the term to mean either large droplet or aerosol transmission.However, these terms are often used confusingly when discussing specific infection control interventions for individual pathogens that are accepted to be mostly transmitted by the airborne (aerosol) route (e.

Varicella Virus-Host Interactions During Latency and Reactivation: Lessons From Simian Varicella Virus.

Front Microbiol 2018 21;9:3170. Epub 2018 Dec 21.

Department of Molecular Biology and Biochemistry, University of California, Irvine, Irvine, CA, United States.

Varicella zoster virus (VZV) is a neurotropic alphaherpesvirus and the causative agent of varicella (chickenpox) in humans. Following primary infection, VZV establishes latency in the sensory ganglia and can reactivate to cause herpes zoster, more commonly known as shingles, which causes significant morbidity, and on rare occasions mortality, in the elderly. Because VZV infection is highly restricted to humans, the development of a reliable animal model has been challenging, and our understanding of VZV pathogenesis remains incomplete. Read More

Systematic review and meta-analysis of chickenpox vaccination and risk of herpes zoster: a quantitative view on the "exogenous boosting hypothesis".

Clin Infect Dis 2018 Dec 24. Epub 2018 Dec 24.

Immunization Unit, Robert Koch Institute, Berlin, Germany.

Background: The "exogenous boosting hypothesis" postulates that re-exposure to circulating varicella zoster virus (VZV) over the life span inhibits reactivation of VZV. Consequently, if circulation of VZV is suppressed by introduction of chickenpox vaccination, incidences of herpes zoster may rise. Our aim was to investigate quantitative effects of chickenpox vaccination on herpes zoster incidence at the population level. Read More

Global impact of varicella vaccination programs.

Hum Vaccin Immunother 2019 10;15(3):645-657. Epub 2018 Dec 10.

a Centro Infant, Department of Pediatrics , School of Medicine, Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS) , Porto Alegre , Rio Grande do Sul state , Brazil.

Although varicella is usually a mild and self-limited disease, complications can occur. In 1998, the World Health Organization recommended varicella vaccination for countries where the disease has a significant public health burden. Nonetheless, concerns about a shift in the disease to older groups, an increase in herpes zoster in the elderly and cost-effectiveness led many countries to postpone universal varicella vaccine introduction.

Clinical Features of Varicella-Zoster Virus Infection.

Viruses 2018 11 2;10(11). Epub 2018 Nov 2.

Department of Pediatrics, Columbia University College of Physicians and Surgeons, New York, NY 10032, USA.

Varicella-zoster virus (VZV) is a pathogenic human herpes virus that causes varicella (chickenpox) as a primary infection, following which it becomes latent in peripheral ganglia. Decades later, the virus may reactivate either spontaneously or after a number of triggering factors to cause herpes zoster (shingles). Varicella and its complications are more severe in the immunosuppressed. Read More

Understanding the role of exogenous boosting in modeling varicella vaccination.

Expert Rev Vaccines 2018 11 5;17(11):1021-1035. Epub 2018 Nov 5.

b Center for Outcomes Research and Real World Evidence , Merck & Co., Inc , Kenilworth , NJ , USA.

Introduction: The exogenous boosting (EB) hypothesis posits that cell-mediated immunity is boosted for individuals reexposed to varicella-zoster virus (VZV). Historically, mathematical models of the impact of universal childhood varicella vaccination (UVV) have used limited data to capture EB and often conclude that UVV will temporarily increase herpes zoster (HZ) incidence.

Areas Covered: We updated a 2013 systematic literature review of 40 studies to summarize new evidence from observational or modeling studies related to EB and its parameterization. Read More

Is acyclovir effective for the treatment of varicella in children and adolescents?

Medwave 2018 Oct 4;18(6):e7269. Epub 2018 Oct 4.

Proyecto Epistemonikos, Santiago, Chile; Departamento de Medicina Familiar, Facultad de Medicina, Pontificia Universidad Católica de Chile, Santiago, Chile. Email: Address: Centro Evidencia UC, Pontificia Universidad Católica de Chile, Diagonal Paraguay 476, Santiago, Chile.

Introduction: Varicella (chickenpox) is a frequent and highly contagious infectious disease, caused by the Varicella zoster virus. Traditionally, it has been recommended to focus on the management of symptoms, since there is controversy about the role of antivirals, particularly in children and adolescents.

Methods: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. Read More

Herpes zoster in the context of varicella vaccination - An equation with several variables.

Vaccine 2018 11 8;36(46):7072-7082. Epub 2018 Oct 8.

Santa Casa de Sao Paulo School of Medical Sciences, Sao Paulo, Brazil.

Background: Varicella and herpes zoster (HZ), diseases both caused by the varicella zoster virus (VZV), are vaccine-preventable. However, the hypothesis that childhood varicella vaccination may increase the incidence of HZ hinders varicella universal routine vaccination (URV) implementation in many countries.

Methods: This non-systematic and narrative review of the literature considers the burden of varicella and HZ, and the effectiveness of the respective vaccines. Read More

Toll-like receptor signaling induces the expression of lympho-epithelial Kazal-type inhibitor in epidermal keratinocytes.

J Dermatol Sci 2018 Nov 15;92(2):181-187. Epub 2018 Sep 15.

Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Science, Okayama, Japan.

Background: Lympho-epithelial Kazal-type inhibitor (LEKTI) tightly controls the activities of serine proteases such as kallikrein-related peptidase (KLK) 5 and KLK7 in the epidermis. LEKTI is known to be an essential molecule for the epidermal skin barrier, as demonstrated by SPINK5 nonsense mutation, which results in Netherton syndrome. Toll-like receptors (TLRs) recognize pathogen-associated molecular patterns or damage-associated molecular patterns and produce inflammatory cytokines, chemokines, and antimicrobial peptides.
