L’ESPERIENZA DELLA SICILIA QUALE REGIONE CAPOFILA NELLA INTRODUZIONE DELLA VACCINAZIONE UNIVERSALE CONTRO I ROTAVIRUS

La gastroenterite da rotavirus (GARV) rappresenta uno dei principali bisogni assistenziali durante l’età pediatrica. Purtroppo, in Italia, in assenza di notifica obbligatoria e di specifici sistemi di sorveglianza, le uniche valutazioni epidemiologiche disponibili sulle GARV sono rese possibili dall’analisi delle ospedalizzazioni. Il presente lavoro ha avuto l’obiettivo di valutare le ospedalizzazioni per GARV e per intussuscezione, avvenute in Sicilia in soggetti di età compresa tra 0 e 60 mesi, negli anni 2003-2012 (periodo prevaccinale) e 2013 (anno di introduzione della vaccinazione antirotavirus). Nel periodo in esame si sono osservate 9.886 ospedalizzazioni per GARV con una media annua di 899 casi. La maggior parte dei ricoveri (62,3%) è stata registrata nella fascia di età compresa tra 0 e 2 anni con una progressiva riduzione negli anni di vita successivi. Durante il 2013 si è osservata una copertura vaccinale regionale attestatasi tra il 30 ed il 40% per la prima dose ed il 25-35% per la seconda dose. Nello stesso anno si è assistito ad una riduzione dei casi di GARV di circa il 38,9% nei soggetti di età 0-5 anni (931 casi/anno nel 2003-2012 vs. 569 nel 2013) e superiore al 50% nella fascia di età 0-11 mesi (277 casi/anno nel 2003-2012 vs. 137 nel 2013). Diversamente, nel 2013 il numero di ospedalizzazioni per intussuscezione in soggetti di età compresa tra 0 ed 11 mesi si è mantenuta in linea con quanto osservato in epoca prevaccinale (15 casi nel 2013 vs. 15,4 casi/anno osservati in media tra 2003 e 2012). I dati presentati evidenziano l’importante peso assistenziale che le GARV hanno annualmente in Sicilia e supportano l’efficacia della vaccinazione nella riduzione significativa dei casi di ospedalizzazione per GARV in assenza di incrementi di rischio di intussuscezione

Determinants of European parents' decision on the vaccination of their children against measles, mumps and rubella: A systematic review and meta-analysis

Low measles, mumps and rubella (MMR) immunization levels in European children highlight the importance of identifying determinants of parental vaccine uptake to implement policies for increasing vaccine compliance. The aim of this paper is to identify the main factors associated with partial and full MMR vaccination uptake in European parents, and combine the different studies to obtain overall quantitative measures. This activity is included within the ESCULAPIO project, funded by the Italian Ministry of Health. ORs and CIs were extracted, sources of heterogeneity explored and publication bias assessed. Forty-five papers were retrieved for the qualitative study, 26 of which were included in the meta-analysis. The following factors were associated with lower MMR vaccine uptake: misleading knowledge, beliefs and perceptions on vaccines (OR 0.57, CI 0.37-0.87); negative attitudes and behaviors toward vaccination (OR 0.71, CI 0.52-0.98); demographic characteristics, such as different ethnicity in Southern populations (OR 0.44, CI 0.31-0.61), higher child's age (OR 0.80, CI 0.76-0.85); low socio-economic status (OR 0.64, CI 0.51-0.80), especially low income (OR 0.39, CI 0.25-0.60) and education (OR 0.64, CI 0.48-0.84), high number of children (OR 0.54, CI 0.42-0.69), irregular marital status (OR 0.80, CI 0.66-0.96). The factors explaining heterogeneity were country location, administration modality, collection setting and responses reported on MMR alone or in combination. Findings from this study suggest policy makers to focus communication strategies on providing better knowledge, correct beliefs and perceptions on vaccines, and improving attitudes and behaviors in parents; and to target policies to people of ethnic minority from Southern Europe, low educated and deprived, with higher number of children and non-married marital status

Information sources and knowledge on vaccination in a population from southern Italy: The ESCULAPIO project

Vaccine knowledge of the general population is shaped by different information sources and strongly influences vaccination attitudes and uptake. The CCM-Italian Ministry of Health ESCULAPIO project attempted to identify the role of such information sources, in order to address adequate strategies to improve information on vaccines and vaccine preventable diseases. In the present study, data on 632 adults from Southern Italy regarding information sources were collected, and their perceived and actual knowledge on vaccinations were compared and analyzed in relation to socio-demographic characteristics and information sources. The main reported reference sources were general practitioners (GPs) (42.5%) and pediatricians (33.1%), followed by mass media (24.1%) and the Internet (17.6%). A total of 45.4% reported they believed to be informed (45.4%), while those estimated to be truly informed were 43.8%. However, as showed in the multivariate logistic regression, people having the perception to be correctly informed ascribed their good knowledge to their profession in the health sector (Adj OR 2.28, CI 1.09–4.77, p < 0.05) and to friends/relatives/colleagues (AdjOR 6.25, CI 2.38–16.44, p < 0.001), while the non-informed population thought the responsibility had to be attributed to mass media (AdjOR 0.45, CI 0.22–0.92, p < 0.05). Those showing the real correct information, instead, were younger (AdjOR 1.64, CI 1.04–2.59, p < 0.05), and their main reference sources were pediatricians (AdjOR 1.63, CI 1.11–2.39, p < 0.05) and scientific magazines (Adj OR 3.39, CI 1.51–7.59, p < 0.01). Only 6% knew the “VaccinarSì” portal, developed to counter the widespred antivaccine websites in Italy. The post-survey significant increase of connections to “VaccinarSi” could be ascribed to the counselling performed during questionnaire administration. Strategies to improve information about vaccination should be addressed to fortifying healthcare workers knowledge in order to make them public health opinion leaders. General population should be provided with correct indications on trustworthy websites on vaccines to contrast false information supplied by anti-vaccinists on their own websites or social networks pages and on the mass media

Hospitalisation of children aged 0-59 months with rotavirus gastro-enteritis before the introduction of routine vaccination (Sicily 2003-2012).

Background: Recent evidence demonstrates that rotavirus vaccination is the best strategy for reducing rotavirus gastro-enteritis (RVGE) in young children. Aims: This study describes the epidemiology of RVGE hospitalisation of Sicilian children before universal rotavirus vaccination was introduced into the regional immunisation programme in January 2013. Methods: An observational study was undertaken by analyzing data obtained from the Regional Hospital Discharge database, including hospitalisation from 2003 to 2012 of subjects aged 0-59 months who lived in Sicily. Children discharged with the rotavirus-specific ICD-9-CM code of 008·61 on first or any diagnosis stage were considered to be RVGE cases. Results: From 2003 to 2012, 9317 children (median age 19 months, M/F ratio 1·19) were hospitalised with a diagnosis of RVGE. During the study period, annual rates of hospitalisation were between 2·64 and 4·68 cases/1000 children (mean 3·74 cases). Incidence rates were higher in children aged 6-11 months (8·85/1,000 children/year), decreasing significantly with age (P&lt;0·001). RVGE hospitalisation peaked during winter and spring with a statistically significant downward trend throughout summer and autumn. Conclusion: During the study period, the cumulative risk of hospitalisation with RVGE was determined to be about one in 54 Sicilian children in the 1st 5 years of life. Although the present study cannot be considered a proper pharmaco-economic evaluation, the findings suggest that in Sicily the health and economic burden of RVGE hospitalisation strongly supports the introduction of rotavirus vaccination into the regional immunisation programme as a probably cost-saving intervention

Knowledge, Attitudes, and Practices on Energy Drink Consumption and Side Effects in a Cohort of Medical Students

The purpose of this study was to evaluate knowledge, attitudes, and practices concerning energy drink consumption and the prevalence of side effects among medical students. Twenty-two percent of respondents were regular users, particularly men (p <.0005). Users were younger (p =.027) and drank alcohol more frequently (p =.008) than "non-users." Forty-nine percent consumed alcohol associated with energy drinks. Forty-five percent of medical students declared side effects after energy drink consumption, such as palpitations (35%), insomnia (21%), and irritability (20%). The study confirms a large use of energy drinks among students and the occurrence of side effects. The use of energy drinks may influence the ingestion of large amounts of alcohol

The impact of ten years of infant universal Varicella vaccination in Sicily, Italy (2003-2012)

Universal varicella vaccination in Sicily was introduced in infant population since 2003, with a rapidly increasing coverage. Aim of the present study was to analyze changes in the epidemiology of varicella since the introduction of universal vaccination

Has VZV epidemiology changed in Italy? Results of a seroprevalence study

The aim of the study was to evaluate if and how varicella prevalence has changed in Italy. In particular a seroprevalence study was performed, comparing it to similar surveys conducted in pre-immunization era. During 2013–2014, sera obtained from blood samples taken for diagnostic purposes or routine investigations were collected in collaboration with at least one laboratory/center for each region, following the approval of the Ethics Committee. Data were stratified by sex and age. All samples were processed in a national reference laboratory by an immunoassay with high sensitivity and specificity. Statutory notifications, national hospital discharge database and mortality data related to VZV infection were analyzed as well. A total of 3707 sera were collected and tested. In the studied period both incidence and hospitalization rates decreased and about 5 deaths per year have been registered. The seroprevalence decreased in the first year of life in subjects passively protected by their mother, followed by an increase in the following age classes. The overall antibody prevalence was 84%. The comparison with surveys conducted with the same methodology in 1996–1997 and 2003–2004 showed significant differences in age groups 1–19 y. The study confirms that in Italy VZV infection typically occurs in children. The impact of varicella on Italian population is changing. The comparison between studies performed in different periods shows a significant increase of seropositivity in age class 1–4 years, expression of vaccine interventions already adopted in some regions
