1. Hepatitis B virus infection among oncohematologic disease patients in Central Brazil: prevalence, risk factors and immunization
ABSTRACT Introduction: Carriers of oncohematological diseases are at high risk for hepatitis B virus (HBV) infection. Objective and method: To investigate the epidemiology of HBV infection in Goiânia, Central Brazil, 322 individuals with oncohematological diseases (leukemias, Hodgkin lymphoma and non-Hodgkin lymphoma) were interviewed and blood samples we

2. Detection and molecular characterisation of a diagnosis escape variant associated with occult hepatitis B virus in Brazil
BACKGROUND Many studies have identified mutations in the hepatitis B surface antigen (HBsAg) as important factors limiting the ability of commercial serological assays to detect this viral antigen. However, an association between mutations in the HBsAg gene and the occurrence of occult HBV infection (OBI) in patients has not been established. OBJECTIVES

3. Vaccination coverage and immunity against hepatitis B among HIV-infected patients in South Brazil
Evidence-based strategies to improve the hepatitis B virus (HBV) vaccination coverage rates might help to reduce the burden caused by co-infection with HBV and human immuno-deficiency virus (HIV). In this study, the aim was to evaluate the vaccination coverage and immunity against HBV among HIV-infected individuals in South Brazil, and identify factors that

4. Presence of maternal anti-HBs antibodies does not influence hepatitis B vaccine response in Brazilian neonates
Recently, it was suggested that maternal hepatitis B surface antigen antibodies (anti-HBs) acquired transplacentally could play a negative role in newborn infants' immune response to the hepatitis B vaccine. We compared the hepatitis B virus (HBV) vaccine response in infants born to mothers previously vaccinated against HBV (n = 91) to infants born to mother

5. HBV markers in haemodialysis Brazilian patients: a prospective 12-month follow-up
The aim of this study was to determine the prevalence and the incidence of hepatitis B virus (HBV) among haemodialysis (HD) subjects and to evaluate whether testing for serological markers at the time of admission is suitable for HBV screening in this population. One hundred twenty-three patients belonging to two HD centres from São Paulo, Brazil, were test

6. Prevalência dos marcadores das hepatites B e C em adolescentes de Itajaí-SC
Infection by HBV and HCV is a worldwide public health problem, which infect and result in necrosis and inflammation in the liver. When the infection persists, contribute to progression liver cirrhosis and hepatocellular carcinoma. In Brazil, prevalence of HBV is moderate (2% to 7%), with low infection rate in Southern, middle rate in Northeast and Southeast,

7. Cobertura vacinal contra hepatite B em profissionais de saúde de um município de médio porte da região noroeste do Rio Grande do Sul
Introdução: A vacinação contra a hepatite B, aliada às precauções padrão, é um importante instrumento para a prevenção deste agravo em profissionais de saúde, que podem sofrer exposição a material biológico potencialmente contaminado. Objetivos: Estimar a cobertura da vacinação contra a hepatite B, a prevalência de imunizados e de exposiç�

8. Soroprevalência da infecção pelo vírus da hepatite B e avaliação da imunidade vacinal em cirurgiões-dentistas de Goiânia-GO
HBV is considered the major occupational risk agent for dentists. The hepatitis B vaccination is hardly recommended to these professionals who have frequent contact with blood and saliva from patients. To determine the HBV infection rate as well as the vaccine immunity for dentists from Goiânia-GO, a randomized sample of 678 professionals participated in th

9. Seropositivity for hepatitis B virus, vaccination coverage, and vaccine response in dentists from Campo Grande, Mato Grosso do Sul, Brazil
This study investigated the seropositivity for hepatitis B virus (HBV), the vaccination index, and the vaccine response index in dentists from Campo Grande, MS. Blood samples from 474 dentists (63.7% women and 36.3% men), with a mean age of 38.5 ± 10.5 years were analyzed by enzyme-linked immunosorbent assay to detect the serological markers: HBsAg, anti-HB

10. Seroepidemiology of hepatitis B virus infection and high rate of response to hepatitis B virus Butang®vaccine in adolescents from low income families in Central Brazil
In order to evaluate the seroepidemiology and response to Butang® vaccine in adolescents from low income families in Central Brazil, blood samples of 664 adolescents were tested for hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), and hepatitis B surface antibody (anti-HBs) markers, and multiple logistical regression analysis was c

11. HBV vaccination of HCV-infected patients with occult HBV infection and anti-HBc-positive blood donors
Anti-HBc positivity is a frequent cause of donation rejection at blood banks. Hepatitis B virus (HBV) infection may also occur in HBsAg-negative patients, a situation denoted occult infection. Similarly, very low levels of HBV-DNA have also been found in the sera of patients with chronic hepatitis C virus (HCV) infection, even in the absence of serum HBsAg.

12. ASPECTOS EPIDEMIOLÃGICOS E CLÃNICOS DA HEPATITE C NO MUNICÃPIO DE FEIRA DE SANTANA-BA
This study describes the epidemiological and clinical characteristics of hepatitis C in Feira de Santana, Bahia, Brazil. Among the objectives we sought to describe socio-demographic data, smoking, use of alcoholic drinks, anthropometric evaluation, diagnosis of disease, antiviral therapy and its results, risk factors, HIV or hepatitis B coinfection, hepatiti
