BACKGROUND Hepatitis B virus (HBV) vaccination has effectively reduced the acute and chronic infection rates in recent years. Since 1983, HBV vaccination has been recommended for all neonates in Korea. METHODS This article reviews the impacts of HBV vaccination throughout the past 25 years in Korea. Before the introduction of the HBV vaccination program, approximately 8% of the general Korean...
background: blood transfusion plays a great role in public health and the blood safety still has remained a main concern. hbv has been considered as one of the most prevalent blood borne infections. it is estimated that chronic hbv affects 350-400 million people worldwide. comprehensive knowledge about hbv has high importance in iran due to high number of blood dependent patients. material and ...
Background: Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are the main causes of severe liver failure worldwide. This study was conducted to evaluate the incidence rate and trend of these infections over six successive years from 2008 to 2013 in Ilam Province, western Iran. Methods: We studied the registered data of HBV and HCV based on the National Notifiable Diseases Surveil...
Hepatitis B virus/hepatitis C virus (HBV/HCV) dual infection is common among high-risk individuals. To characterize the virological and immunological features of patients with HBV/HCV dual infection, we enrolled 1,049 individuals who have been identified as injection drug users. Patients were divided into single and dual infection groups according to the serological markers. We found the averag...
OBJECTIVE Current data on the prevalence of occult hepatitis B virus (HBV) infection in HIV-positive individuals conflict. As occult HBV infection could have an impact on the outcome of liver disease in HIV-positive patients, we investigated a large number of HIV-positive/HBV-surface-antigen (HBsAg) negative subjects with hepatitis C virus (HCV) infection by using the 'gold standard' approach f...
INTRODUCTION To investigate the impact of intrahepatic cholestasis of pregnancy (ICP) with hepatitis B virus (HBV) infection on perinatal outcomes. METHODS In the study, 200 pregnant women were divided into four groups, including 50 cases with ICP and HBV infection, 50 cases with ICP, 50 cases with HBV infection, and 50 healthy pregnancies. The delivery process and perinatal outcomes were ana...
Coinfection of blood-borne hepatitis B and hepatitis C viruses (HBV and HCV, respectively) in human immunodeficiency virus type 1 (HIV-1)-positive individuals frequently occurs in inmate population and peculiar viral strains and patterns of virological markers may be observed.Plasma from 69 HIV-1-positive inmates was obtained from 7 clinical centers connected with correctional centers in differ...
OBJECTIVES This study aimed to determine the HBV infection status of 135 patients with DLBCL (diffuse large B cell lymphoma), to analyze the overall survival (OS) and progression-free survival (PFS) of the different HBV infection status groups, and to discuss the relationship between HBV serological test results and the prognosis of DLBCL patients. METHODS A retrospective analysis was perform...
Aim: This study was conducted to ascertain the level of coexistence of Hepatitis B virus (HBV) and HIV and to determine their significant association. Both HBV and HIV share the same routes of infection. Methods: The study was conducted on 500 persons consisting 250 subjects who tested positive to HIV and 250 subjects who tested positive to HBV. HIV positive individuals were further tested for ...
The mechanisms by which HBV establishes and maintains chronic infection are poorly understood. Although adult acquired HBV is generally cleared by a robust immune response, most individuals infected at childbirth or in very early childhood develop lifelong chronic infection. In addition, acute infections are unresolved in approximately 5% of individuals infected in adulthood. The host cell mech...
