Effect of the varicella vaccination on the clinical characteristics of herpes zoster cases aged 20 years and under / 中华预防医学杂志

To discuss the effect of varicella vaccination on the clinical characteristics of herpes zoster (shingles) cases aged 20 years and under, and analyze its clinical features. Based on the Yichang Health Big Data Platform, a descriptive study was conducted to collect the information of cases aged 20 years and under in three medical institutions of Yichang Central People's Hospital, Yichang First People's Hospital and Yichang Second People's Hospital from March 2019 to September 2020. According to the history of varicella vaccine, cases were divided into vaccination group and non-vaccination group, and their clinical features and outcomes were compared. The results showed that 46 shingles cases, aged from 7 to 20 years old, were included in this study. 26 males (56.5%), 20 females (43.5%), 15 cases in vaccination group (32.6%) and 31 cases in non-vaccination group (67.4%). 28 cases had thoracic involvement, followed by lumbar (n=8), cranial (n=7) involvements and extremities (n=7). The spread of herpes skin area: 2 cases involved too large area, 21 cases of 10 cm×10 cm, 14 cases of 5 cm×5 cm, 9 cases of 1 cm×1 cm. Herpes number: 26 cases had 10-49 herpes, followed by <10 herpes (n=9), uncountable herpes (n=7) and 50-99 herpes (n=4). The clinical course[M(Q1,Q3)] lasted 20.5 (13.5,24.8) d averagely, 5 cases had postherpetic neuralgia (PHN) and 1 case had respiratory complications. Shingles decrustation time was significantly shorter in vaccination group (Z=-2.01, P<0.05), and there was no significant difference in other characteristics by vaccination. In conclusion, the number and spread of shingles in most children and adolescents are less, and the complications such as PHN are less. Varicella vaccination can reduce the decrustation time and relieve shingles cases with some clinical symptoms.

This editorial article aims to help our health teams carry out a shared decision-making process with their patients regarding this new vaccine. (AU)

O conhecimento dos profissionais de saúde sobre vacinação de pessoas vivendo com HIV - uma revisão integrativa / El conocimiento de los profesionales de la salud sobre la vacunación de personas que viven con VIH - revisión integradora / Health professionals' knowledge about vaccination of people living with HIV - an integrative review

Resumo Objetivo Identificar evidências na literatura acerca do conhecimento dos profissionais de saúde sobre vacinação das pessoas vivendo com HIV. Método Trata-se de uma revisão integrativa. Para a busca, foram utilizados os descritores: pessoal de saúde (health personnel), conhecimento (knowledge), vacinação (vaccination), HIV e seus sinônimos, sem utilização de filtros, nas bases de dados Pubmed, Biblioteca Virtual em Saúde, Web of Science, Cumulative Index to Nursing and Allied Health Literature, Embase, Scopus, Science Direct e Cochrane. Foram incluídos apenas artigos primários analisados por meio do aplicativo RAYYAN. Resultados De 601 publicações iniciais, apenas cinco constituíram a amostra final, todas identificadas no Pubmed publicadas entre 2013 e 2018, sendo nenhum estudo brasileiro. A maioria das publicações estava relacionada a alguma vacina específica e não abordava todo o calendário vacinal. Conclusão e implicações para a prática O déficit de conhecimento dos profissionais de saúde, em relação às vacinas indicadas às pessoas vivendo com HIV, foi o principal aspecto identificado, resultando em insegurança dos profissionais. Há a necessidade de educação permanente das equipes multiprofissionais dos serviços especializados e da atenção primária visando diminuir as barreiras e aumentar a cobertura vacinal desta clientela.

Abstract Objective to identify evidence in the literature about the health professionals' knowledge concerning vaccination of people living with HIV. Method This is an integrative review. In this research, the descriptors used were the following: health personnel, knowledge, vaccination, HIV and its synonyms, without the use of filters, in the Pubmed, Virtual Health Library, Web of Science, Cumulative Index to Nursing and Allied Health Literature, Embase, Scopus, Science Direct and Cochrane databases. Only primary articles analyzed using the RAYYAN application were included. Results Out of 601 initial publications, only five comprised the final sample, all identified in Pubmed and published between 2013 and 2018, with no Brazilian studies. Most of the publications were related to a specific vaccine and did not address the entire vaccination schedule. Conclusion and implications for the practice The health professionals' lack of knowledge in relation to vaccines indicated to people living with HIV was the main aspect identified, resulting in insecurity among the professionals. There is a need for permanent education of the multidisciplinary teams of specialized services and primary care in order to reduce barriers and to increase vaccination coverage for this clientele.

Vaccines for preventing herpes zoster in older adults

BACKGROUND: Herpes zoster or, as it is commonly called, 'shingles' is a neurocutaneous disease characterised by the reactivation of varicella zoster virus (VZV), the virus that causes chickenpox, which is latent in the dorsal spinal ganglia when immunity to VZV declines. It is an extremely painful condition which can often last for many weeks or months, impairing the patient's quality of life. The natural aging process is associated with a reduction of cellular immunity which predisposes to herpes zoster. Vaccination with an attenuated form of VZV activates specific T cell production, therefore avoiding viral reactivation. A herpes zoster vaccine with an active virus has been approved for clinical use among older adults by the Food and Drug Administration and has been tested in large populations. OBJECTIVE: To evaluate the effectiveness and safety of vaccination for preventing herpes zoster in older adults. METHODS Search methods: We searched the following sources for relevant studies: CENTRAL 2012, Issue 7, MEDLINE (1948 to July week 1, 2012), EMBASE (2010 to July 2012), LILACS (1982 to July 2012) and CINAHL (1981 to July 2012). We also reviewed reference lists of identified trials and reviews for additional studies. Selection criteria: Randomised controlled trials (RCTs) or quasi-RCTs comparing zoster vaccine with placebo or no vaccine, to prevent herpes zoster in older adults (mean age > 60 years). Data collection and analysis: Two review authors independently collected and analysed data using a data extraction form. They also carried out an assessment of risk of bias. MAIN RESULTS: We identified eight RCTs with a total of 52,269 participants. Three studies were classified at low risk of bias. The main outcomes on effectiveness and safety were extracted from one clinical trial with a low risk of bias. Four studies compared zoster vaccine versus placebo; one study compared high-potency zoster vaccine versus low-potency ...

Impact of methodology on the results of economic evaluations of varicella vaccination programs: is it important for decision-making? / Impacto da metodologia nos resultados de avaliações econômicas de programas de vacinação da varicela: é importante para o processo de tomada de decisão?

This study aims to review the literature on economic evaluation of childhood varicella vaccination programs and to discuss how heterogeneity in methodological aspects and estimation of parameters can affect the studies' results. After applying the inclusion criteria, 27 studies published from 1980 to 2008 were analyzed in relation to methodological differences. There was great heterogeneity in the perspective adopted, evaluation of indirect costs, type of model used, modeling of the effect on herpes zoster, and estimation of vaccine price and efficacy parameters. The factor with the greatest impact on results was the inclusion of indirect costs, followed by the perspective adopted and vaccine price. The choice of a particular methodological aspect or parameter affected the studies' results and conclusions. It is essential that authors present these choices transparently so that users of economic evaluations understand the implications of such choices and the direction in which the results of the analysis were conducted.

O presente trabalho tem por objetivo rever a literatura sobre avaliação econômica de programas de vacinação infantil contra varicela, e discutir como a heterogeneidade em aspectos metodológicos e na estimativa dos parâmetros pode afetar os resultados dos estudos. Após aplicação dos critérios de inclusão, 27 estudos do período de 1980 a 2008 foram analisados com relação às diferenças metodológicas. Observou-se grande heterogeneidade na perspectiva adotada, valoração dos custos indiretos, tipo de modelo empregado, modelagem do efeito no herpes zoster, e na estimativa dos parâmetros de preço e eficácia da vacina. O fator que mais impactou os resultados foi a inclusão dos custos indiretos seguido da perspectiva e preço de vacina adotados. A escolha de um determinado aspecto metodológico ou parâmetro afetou os resultados e conclusões dos estudos. É de fundamental importância que os autores apresentem essas escolhas com transparência para que os usuários das avaliações econômicas compreendam as repercussões dessas escolhas, e em qual direção os resultados das análises foram conduzidos.
