“…Entre as populações indígenas brasileiras, pesquisas têm demonstrado alta endemicidade da infecção pelo HBV e HDV, com variações quanto à prevalência, à idade e ao modo de aquisição dos vírus 16,17,18,19,20,21,22,23,24,25,26,27 .…”

Com o objetivo de estudar a prevalência dos vírus das hepatites B (HBV) e D (HDV), nas aldeias Apyterewa e Xingu, do grupo Parakanã, e avaliar o impacto da vacinação contra a hepatite B, iniciada nessas aldeias em 1995, foram coletadas, em 2004, 258 amostras de soro para análise dos marcadores sorológicos das hepatites B e D, por técnicas imunoenzimáticas; cujos resultados revelaram padrão de endemicidade moderada com prevalência total de infecção pelo HBV de 55,7%, com 5,4% de portadores do vírus, na aldeia Apyterewa, e de 49,5%, com 1,1% de portadores, na Xingu; 31,4% de anti-HBs+ como marcador isolado nas duas aldeias, e não foi detectada sorologia positiva para o HDV entre portadores do HBV. Caracterizamos, em base laboratorial, a presença de portadores crônicos do HBV, ausência de portadores do HDV e emergência de perfil vacinal entre os susceptíveis, confirmando a efetividade e a necessidade de manter a vacinação, principalmente no primeiro ano de vida, e, ainda, a necessidade de desenvolver vigilância epidemiológica efetiva para detecção precoce da infecção pelo HDV, entre os portadores do HBV.

“…(18) The lifestyle of Brazilian indigenous people living in this region and limited access to vaccination put these societies at risk of HBV and HVD (hepatitis virus D) infection. (19)(20)(21)(22) Working in partnership with the Ministry of Health, the Instituto Evandro Chagas (IEC), located in the state of Pará (PA), Brazil, began to collect specimens from patients with fever and jaundice, in the city of Lábrea, in the Amazon region, in 1951. In the following decade, five child deaths were investigated.…”

Objective: To detect and treat cases of viral hepatitis B, C and D in patients seen at the Native American Outpatient Clinic of Universidade Federal de São Paulo. Methods: This sample comprised 81 indigenous recruited between 2018 and 2020. Volunteers were aged 7 months to 70 years (mean age of 28±20 years), belonged to 26 ethnic groups spanning the Brazilian territory and answered a questionnaire, which was attached to their medical records. Peripheral blood samples (20mL) were collected, transported to the Clinical Laboratory of Hospital Israelita Albert Einstein, processed, and tested for markers of viral hepatitis B, C and D. Results: In this study, 39 (48.1%) individuals were anti-HBs (+) only, 13 (16.0%) individuals were anti-HBs (+) and anti-HBc (+), and 28 (34.6%) individuals were negative for all markers. No anti-HBc IgM+ samples were found. No cases of hepatitis C and D were found. Conclusion: This analysis provided evidence of previous infection by the hepatitis B virus. These findings led to prescription of vaccination against hepatitis B to all participants who were negative for all viral hepatitis B markers, given records of prior hepatitis B vaccination were unreliable.
