La couverture vaccinale contre la grippe saisonnière du personnel soignant en gériatrie : mise au point

2016

Resume Position du probleme La vaccination antigrippale des professionnels de sante semble representer l’une des actions preventives des plus efficaces face a une pathologie a haut risque d’epidemie nosocomiale et potentiellement grave en milieu geriatrique. Ce travail avait pour objectif de faire une mise au point sur le statut vaccinal antigrippal chez le personnel soignant en geriatrie et les raisons expliquant leur reticence vis-a-vis de cette vaccination, afin d’emettre des propositions d’amelioration de la couverture vaccinale. Methode Une recherche bibliographique des articles publies depuis 2000 dans le domaine de la geriatrie, des maladies infectieuses ou de la pneumologie a ete re…

Temporal association between the influenza virus and respiratory syncytial virus (RSV): RSV as a predictor of seasonal influenza.

2016

SUMMARYEpidemiologists agree that there is a prevailing seasonality in the presentation of epidemic waves of respiratory syncytial virus (RSV) infections and influenza. The aim of this study is to quantify the potential relationship between the activity of RSV, with respect to the influenza virus, in order to use the RSV seasonal curve as a predictor of the evolution of an influenza virus epidemic wave. Two statistical tools, logistic regression and time series, are used for predicting the evolution of influenza. Both logistic models and time series of influenza consider RSV information from previous weeks. Data consist of influenza and confirmed RSV cases reported in Comunitat Valenciana (…

Cardiac troponin elevation in patients with influenza virus infections

2021

The association between acute infections and cardiac injury, including myocarditis and acute myocardial infarction, is now well established. We have performed a systematic literature review for analyzing the results of epidemiological studies that measured cardiac troponins (cTn) in patients with Influenza virus infections. Overall, 14 articles were finally identified and analyzed. Taken together, the results of the scientific literature suggest that cTn elevation is a relatively rare phenomenon in patients with Influenza virus infection, with frequency generally comprised between 0 and 33%, more likely in elderly patients with significant comorbidities. In patients with modest cTn elevatio…

THE EFFICACY AND SAFETY OF INFLUENZA VACCINATION IN OLDER PEOPLE: AN UMBRELLA REVIEW OF EVIDENCE FROM META-ANALYSES OF BOTH OBSERVATIONAL AND RANDOMI…

2020

Vaccination is the main public health intervention to prevent influenza. We aimed to evaluate the efficacy and safety of influenza vaccination including systematic reviews and meta-analyses of observational studies and randomized controlled trials (RCTs). Peer-reviewed systematic reviews with meta-analyses of prospective studies that investigated the association of influenza vaccination with any health-related outcome, as well as RCTs that investigated the efficacy and safety of influenza vaccination, were included. Among 1240 references, 6 meta-analyses were included. In cohort studies of community-dwelling older people influenza vaccination was associated with a lower risk of hospitalizat…

The molecular epidemiology and evolutionary dynamics of influenza B virus in two Italian regions during 2010-2015: The experience of Sicily and Ligur…

2016

Molecular epidemiology of influenza B virus remained poorly studied in Italy, despite representing a major contributor to seasonal epidemics. This study aimed to reconstruct the phylogenetic relationships and genetic diversity of the hemagglutinin gene sequences of 197 influenza B strains circulating in both Southern (Sicily) and Northern (Liguria) Italy between 2010 and 2015. Upper respiratory tract specimens of patients displaying symptoms of influenza-like illness were screened by real-time RT-PCR assay for the presence of influenza B virus. PCR-positive influenza B samples were further analyzed by sequencing. Neighbor-joining phylogenetic trees were constructed and the amino-acid alignm…

Co-circulation of the two influenza B lineages during 13 consecutive influenza surveillance seasons in Italy, 2004-2017

2019

AbstractBackgroundSince 1985, two antigenically distinct lineages of influenza B viruses (Victoria-like and Yamagata-like) have circulated globally. Trivalent seasonal influenza vaccines contain two circulating influenza A strains but a single B strain and thus provide limited immunity against circulating B strains of the lineage not included in the vaccine. In this study, we describe the characteristics of influenza B viruses that caused respiratory illness in the population in Italy over 13 consecutive seasons of virological surveillance, and the match between the predominant influenza B lineage and the vaccine B lineage, in each season.MethodsFrom 2004 to 2017, 26,886 laboratory-confirme…

The effectiveness of influenza vaccination in preventing hospitalisations of elderly individuals in two influenza seasons: a multicentre case-control…

2017

Influenza vaccination may limit the impact of influenza in the community. The aim of this study was to assess the effectiveness of influenza vaccination in preventing hospitalisation in individuals aged ≥ 65 years in Spain. A multicentre case–control study was conducted in 20 Spanish hospitals during 2013/14 and 2014/15. Patients aged ≥ 65 years who were hospitalised with laboratory-confirmed influenza were matched with controls according to sex, age and date of hospitalisation. Adjusted vaccine effectiveness (VE) was calculated by multivariate conditional logistic regression. A total of 728 cases and 1,826 matched controls were included in the study. Overall VE was 36% (95% confidence inte…

The Socio-Economic Health Deprivation Index and its association with mortality and attitudes towards influenza vaccination among the elderly in Paler…

2019

Abstract Introduction Inequality levels are associated with vaccination coverage among the older and at risk population hypothesizing socio-economic status (SES) as a determinant of health status. The aim of the study was to evaluate the trend of health outcome and socio-health-economic-status deprivation index (IDPA) among elderly people in Palermo city, Italy . Methods The Palermo Unit of 2015 CCM project deal with collection of data useful to validate IDPA using the Italian census data from 2009 to 2015 on overall mortality and cause of death. The preventive outcome used to validate the IDPA index was vaccination coverage from 2009-2010 to 2014-2015 influenza season among Palermo elderly…

Interim 2017/18 influenza seasonal vaccine effectiveness: combined results from five European studies

2018

Between September 2017 and February 2018, influenza A(H1N1)pdm09, A(H3N2) and B viruses (mainly B/Yamagata, not included in 2017/18 trivalent vaccines) co-circulated in Europe. Interim results from five European studies indicate that, in all age groups, 2017/18 influenza vaccine effectiveness was 25 to 52% against any influenza, 55 to 68% against influenza A(H1N1)pdm09, -42 to 7% against influenza A(H3N2) and 36 to 54% against influenza B. 2017/18 influenza vaccine should be promoted where influenza still circulates. Funding: The five studies have received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 634446 to conduct the study in…
