Abstract
Resumen Objetivo: identificar la situación de la vacunación y serología contra la hepatitis B entre agentes comunitarios de la salud, vacunar contra el virus de la hepatitis B y evaluar la respuesta inmunológica de los agentes susceptibles. Método: fase I, estudio transversal y descriptivo, entre agentes comunitarios de la salud de una capital de la región centro oeste, por medio de cuestionario autoadministrado, verificación del carné de vacunación y extracción de sangre para comprobar los marcadores serológicos para la hepatitis B. Fase II, estudio de cohorte realizado en trabajadores vacunados no inmunes e identificados en la Fase I; estos recibieron una dosis de la vacuna (dosis de desafío) y realizaron el test serológico. Resultados: participaron del estudio 109 agentes. La mayoría tenía registro de vacunación (97; 89,0%) y de cobertura de vacunación (75; 77,3%); el marcador anti-HBs (Anticuerpos contra el virus de la hepatitis B) aislado fue detectado en 78 (71,6%) de los agentes. La prevalencia de exposición al virus de la hepatitis B fue de 8,2%. De los diez agentes vacunados no inmunes, después de la dosis desafío, uno permaneció susceptible. Conclusión: a pesar de que la mayoría de los trabajadores estaban vacunados y presentaron respuesta inmunológica para la hepatitis B, la susceptibilidad, después de la dosis desafío, fue identificada. Por tanto, es necesario que exista un programa de vigilancia de la situación de vacunación y estado serológico para este virus, para promover la seguridad de estos trabajadores.

Abstract
OBJECTIVE to analyze the distribution and spatial autocorrelation of hepatitis B and C detection rates in the state of Paraná, Brazil. METHODS this was an ecological study of hepatitis B and C notifications held on the Notifiable Health Conditions Information System, between 2011 and 2019. Percentage change in detection rates between the first and last three-year periods was estimated. Spatial autocorrelation was analyzed using Moran's index. RESULTS there were 16,699 notifications of hepatitis B, with a greater reduction in detection in the North (-30.0%) and Northwest (-25.9%) macro-regions. There were clusters of high occurrence in the Foz do Iguaçu, Francisco Beltrão and Cascavel regions between 2011 and 2019. There were 10,920 notifications of hepatitis C, with a greater reduction in detection in the Northwest macro-region (-18.9%) and an increase in the West (51.1%). The Paranaguá region recorded a high detection cluster between 2011 and 2016. CONCLUSION hepatitis B and C showed heterogeneous distribution between health regions.

Abstract
OBJECTIVE to identify the vaccination and serological status against hepatitis B among community health workers; to vaccinate against hepatitis B virus and to evaluate the immune response of susceptible workers. METHOD phase I, cross-sectional and descriptive study, among community health workers in a capital city of the Midwest region, through a self-administered questionnaire, checking of vaccination cards, and blood collection for testing of serological markers for hepatitis B. Phase II, cohort study carried out in vaccinated non-immune workers identified in phase I. They received one dose of vaccine (challenge dose) and serological testing. RESULTS a total of 109 workers participated in the study. Most had vaccination record (97; 89.0%) and vaccination completeness (75; 77.3%), while the isolated anti-HBs (Antibodies against hepatitis B virus) marker was detected in 78 (71.6%) workers. The prevalence of hepatitis B virus exposure was 8.2%. Of the ten non-immune vaccinated workers, after challenge dose, one remained susceptible. CONCLUSION although most workers are vaccinated and show immunological response to hepatitis B, susceptibility after challenge dose was identified. Therefore, it is necessary to have a surveillance program of the vaccination situation and serological status for this virus, to promote these workers' safety.

[PMID: 36476118 PMCID: PMC9727992 DOI: 10.1186/s12879-022-07690-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Accepted: 08/17/2022] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Although the prevalence of hepatitis B in Guangzhou, China, is high, the epidemiological trends are not well-documented. We aimed to analyse newly reported hepatitis B cases in Guangzhou between 2009 and 2020 to explore the epidemiological trends and provide insights for the development of control measures. METHODS Information on the population and new cases of hepatitis B in Guangzhou between 2009 and 2020 was obtained from the China Information System for Disease Control and Prevention, which was used to calculate the annual notification rates of hepatitis B by sex, age group (0-9; 10-19; 20-29; 30-39; 40-49; 50-59; ≥ 60 years), and location (urban or rural). Joinpoint regression analysis was used to analyse the temporal trends and calculate the average annual percentage change (AAPC) and annual percentage change (APC) for each identified trend line segment. RESULTS Between 2009 and 2020, 287,034 new cases of hepatitis B were cumulatively reported. The average annual notification rate was 181.13/100,000, and the notification rate showed a long-term downward trend during the period 2009-2020, with an annual decrease of 6.30% (APC - 6.30%; 95% CI - 7.56 to - 5.02%). Men had a significantly higher notification rate than women; however, the sex ratio decreased from a maximum of 2.34 in 2010 to a minimum of 1.54 in 2020. A downward trend in the notification rate was observed in urban areas and an upward trend was observed in rural areas, with an increase in the rural/urban ratio from 0.46 in 2012 to 1.57 in 2020. The notification rate for all age groups showed a decreasing trend from 2009, with the exception of the 50-59 years and ≥ 60 years groups, whose notification rates began to decrease from 2014 and 2015, respectively. CONCLUSIONS Although the overall notification rate of hepatitis B in Guangzhou decreased annually, it remained high. Further, in rural areas, the notification rate has been increasing, and effective measures should be taken to control hepatitis B infection in Guangzhou.

Abstract
The efficacy of hepatitis B vaccination in adults was evaluated by comparison of the positive seroprotection rates and the hepatitis B surface antibody (anti-HBs) geometric mean titers (GMTs) between intensive intervention areas and non-intensive intervention areas after 8 years post-vaccination in the Zhejiang province. Seven cities (towns) in Zhejiang province were selected as intensive intervention areas, and adults in the demonstration areas receive hepatitis B vaccine voluntarily and for free. Other areas were non-intensive intervention areas. A total of 3587 participants received the full vaccination course (three doses), and blood samples were withdrawn 8 years after the first vaccination comprised the immunized group, and 2000 participants constituted the control group. The anti-HBs positive seroprotection rates of the immunized and control groups were 65.0% and 53.0%, respectively. The anti-HBs GMT of the subjects in the immunized group was 26.30 mIU/mL compared to 9.33 mIU/mL in the control group (P < .001). Significant differences were detected in the 24-35-, 36-45-, and 46-55-year-old subgroups in the positive seroprotection rates and the anti-HBs GMTs (P < .001) between the immunized and control groups. Moreover, significant differences were found in the anti-HBs GMT in the 46-55-year-old subgroup between the two groups (P = .02), while no differences were observed in the positive seroprotection rate (P = .428). In conclusion, adults who did not receive the hepatitis B vaccine in infancy and had negative serological markers of hepatitis B, especially adults <47-years-old, need vaccination.
