Molecular epidemiology of Hepatitis delta virus infection in Minas Gerais state from Brazil, an area outside the hyperendemic region of the Amazon Basin

Mem. Inst. Oswaldo Cruz; 114 (), 2019
BACKGROUND Hepatitis delta virus (HDV) infections in hepatitis B virus (HBV) carriers are the most severe form of viral hepatitis. HDV prevalence is high in the Brazilian Amazon, but studies in other regions of the country are still scarce and often underestimated its prevalence by including a small numb...

Serological and molecular retrospective analysis of hepatitis E suspected cases from the Eastern Brazilian Amazon 1993-2014

Abstract INTRODUCTION We evaluated the anti-hepatitis E virus (HEV) antibody prevalence and HEV-RNA in archived serum samples of non-A-C hepatitis, or suspected cases of HEV infection from the Eastern Brazilian Amazon from 1993 to 2014. METHODS Serum samples (n = 318) were tested using ELISA and immu...

Hepatitis E virus infection among rural Afro-descendant communities from the eastern Brazilian Amazon

Abstract INTRODUCTION The prevalence, public health impact, and epidemiological characteristics of hepatitis E virus (HEV) are poorly understood in Brazil. METHODS Serum samples from 535 individuals from three rural Afro-descendant communities located in eastern Brazilian Amazon were collected in Oct...

Seroprevalencia de virus hepatitis E en donantes de sangre en un hospital universitario en Chile

Rev. chil. infectol; 35 (4), 2018
Resumen En Chile, existen escasos estudios de seroprevalencia de anticuerpos IgG anti virus hepatitis E (VHE) en bancos de sangre, entre 4 y 8%. El desarrollo de nuevas técnicas con mayor sensibilidad y especificidad, dan cuenta de un aumento de la seroprevalencia de VHE en diversos países, siendo desc...

Seroprevalence of hepatitis E virus in chronic hepatitis C in Brazil

Braz. j. infect. dis; 22 (2), 2018
ABSTRACT Background and aims: Hepatitis E virus infection in patients with underlying chronic liver disease is associated with liver decompensation and increased lethality. The seroprevalence of hepatitis E virus in patients with chronic hepatitis C in Brazil is unknown. This study aims to estimate the ...

High prevalence of hepatitis E virus antibodies in Sao Paulo, Southeastern Brazil: analysis of a group of blood donors representative of the general population

Braz. j. infect. dis; 21 (5), 2017
Abstract Brazil is a non-endemic country for hepatitis E virus (HEV) infection with seroprevalence from 1% to 4% in blood donors and the general population. However, data on seroprevalence of HEV in the country are still limited. This study evaluated the prevalence of past or present HEV infection in a g...

Hepatitis E seroprevalence and associated factors in rural settlers in Central Brazil

Abstract INTRODUCTION: Prevalence of hepatitis E virus (HEV) infection and associated factors were investigated in rural settlements in Central Brazil. METHODS: A total of 464 settlers were interviewed, and serum samples were tested for anti-HEV IgG/IgM. Positive samples were tested for HEV RNA. RESU...

High Clinical Manifestation Rate in an Imported Outbreak of Hepatitis E Genotype 1 Infection in a German Group of Travellers Returning from India

Ann. hepatol; 16 (1), 2017
Abstract: Background. There are only few reports about travel-associated, imported tropical hepatitis E virus (HEV) genotype 1 infections within Western travellers. We describe the clinical course of a single outbreak of hepatitis E in a German travellers group returning from India and compare the resu...

Effects of Interleukin-4 and Interleukin-12b Gene Polymorphisms on Hepatitis B Virus Vaccination

Ann. hepatol; 16 (1), 2017
Abstract: Approximately 10% of individuals do not respond to hepatitis B virus (HBV) vaccination, i.e. non-responders (NRs). We aimed to investigate the association of interleukin (IL)-4 and IL-12B gene polymorphisms with responsiveness to the HBV vaccine in Korean infants. Among 300 healthy infants (9-1...
