OBJECTIVE To estimate the prevalence of hepatitis B virus (HBV) infection and vaccine-induced immunity in the region of Madrid, and to analyze their evolution over time. METHODS An observational, analytical, cross-sectional study was carried out in the population aged 16-80 years between 2008 and 2009. This was the last of four seroprevalence surveys in the region of Madrid. The prevalence of...

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...

BACKGROUND Blood safety remains an issue of major concern in transfusion medicine in sub-Saharan Africa. Blood-borne agents such as the human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), and Treponema pallidum are among the greatest threats to blood safety for the recipient. This study aimed to determine the seroprevalence and risk factors of HIV, HCV, HBV, an...

Aim: Hepatitis B(HBV), C(HCV) and HIV infections are important parenterally transmitted infections. The aim of this study is to determine the seroprevalence HBsAg, anti-HBs, anti-HCV anti-HIV in patients with preoperative preparation.
 Materials MethodS: Anti-HBs, anti-HCV, tests chemiluminescent enzyme immune-assay method a total 900 applied General Surgery Clinic were evaluated preoperat...

Objective: Viral hepatitis is a major global public health challenge with Hepatitis B virus (HBV) and C (HCV), particularly leading to chronic diseases in several millions of people together they are the most common cause liver cirrhosis, cancer deaths related viral hepatitis. They can be spread by mother-to-child transmission at birth. Despite significant burden it places on pregnant women the...

We have investigated the seroprevalence of hepatitis B and C among Karitiana Indians (n = 119) living in the State of Rondônia, southwestern Brazilian Amazon. The prevalences of anti-HBs and anti-HBc were 16.1% and 35.3%, respectively, with HBsAg being found in only four (3.4%) subjects. Anti-HCV antibodies were detected in two subjects (1.7%). Age-stratified prevalence data suggest that both v...

UNLABELLED BACKGROUND AND RATIONALE FOR THE STUDY: Hepatitis B (HB) is one of the most prevalent occupational infections in health attendance environments. According to the Brazil Ministry of Health, health professionals must be vaccinated against the hepatitis B virus (HBV) and provide laboratory proof of immunization. AIMS To evaluate the seroprevalence of HBV infection and to analyze the r...

BACKGROUND Medical students in the course of their clinical work are at risk of acquiring hepatitis B virus (HBV) infection or transmitting it to their patients. HBV immunization for medical students in Uganda is recommended but not strictly enforced. It is important to assess the prevalence of HBV infection in medical students in order to improve on the interventions to control this infection ...

We set out to determine the seroprevalence of hepatitis B and C among human immunodeficiency virus type-1 (HIV-1) infected individuals in North-Central Nigeria to define the influence of these infections on CD4+ lymphocytes cells among our patients as access to antiretroviral therapy improves across the Nigerian nation. The CD4+ values of 180 confirmed HIV-1 infected individuals were enumerated...

The undertaken study was conducted to find out the seroprevalence and coinfection of HBV and HCV infection among patients seeking hospital care. A total of 845 samples were received at tertiary care hospital of Islamabad and were screened for hepatitis B and C. The ELISA was used to detect antigen for HBV and antibodies for HCV in patient serum. Among 845 collected samples, 255 (30.1%) were ser...
