INTRODUCTION Persistence of the hepatitis B virus (HBV) genome in individuals negative for the HBV surface antigen (HBsAg) reflects occult infection. The aim of this study was to identify occult HBV infection among hemodialysis patients at 5 clinics in Recife, State of Pernambuco, Brazil, between August 2006 and August 2007. METHODS Serum samples underwent enzyme-linked immunosorbent assay to...
Vaccination is the most effective and well-tolerated method of conferring long-term protection against hepatitis A and B viruses (HAV; HBV). Long-term studies are required to characterize the duration of protection and need for boosters. Following primary immunization of 150 and 157 healthy adults with 3-doses of combined hepatitis A/hepatitis B vaccine (HAB; Twinrix™, GSK Vaccines, Belgium) at...
In this report, we examine the adaptability of commercially available serological kits to detect antibodies markers for viral hepatitis in oral fluid samples. We also assessed the prevalence of hepatitis A, B, and C virus-specific antibodies, and related risk factors for these infectious diseases through sensitivity of the tests in saliva samples to evaluate if oralfluid can be an alternative t...
CONTEXT AND OBJECTIVE Selection of healthy blood donors is essential to ensure blood safety. A confidential self-exclusion (CSE) system was designed so that high-risk donors could confidentially exclude their blood from use in transfusions. This study aimed to compare the demographic characteristics and the results from human immunodeficiency virus (HIV), hepatitis B surface (HBS) and hepatitis...
The presence of antibodies to hepatitis B core antigen (anti-HBc) has a different implication than with anti-HBs. Anti-HBc antibodies do not distinguish between active or previous infection, nor to they indicate immunity. All hepatitis B carriers and all patients who have previously been exposed to hepatitis B will be positive for total anti-HBc. Chronic hepatitis B carriers have circulating an...
BACKGROUND In countries with high rates of chronic HBV, the World Health Organization recommends screening all HIV-infected adults for hepatitis B surface antigen (HBsAg) before initiating antiretroviral therapy (ART), and starting HIV-HBV-coinfected patients on regimens containing lamivudine (3TC) or emtricitabine (FTC) plus tenofovir disoproxil fumarate (TDF). Here, we estimated the prevalenc...
BACKGROUND Universal anti-hepatitis-B vaccination of infants and adolescents was implemented in Italy in 1991. We undertook a multicentre study in previously vaccinated individuals to assess the duration of immunity and need for booster, over 10 years after vaccination. METHODS In 1212 children and 446 Italian Air Force recruits vaccinated as infants and adolescents, respectively, we measured...
PURPOSE Hepatitis B virus (HBV) and hepatitis C virus (HCV) are considered to be hepatotropic and are a major cause of hepatocellular carcinoma. However, little is known about the role of HBV and HCV infection in other malignancies. This study aimed to determine whether HBV and HCV infections increase the risk for pancreatic cancer development. PATIENTS AND METHODS At The University of Texas ...
