Today, chronic viral hepatitis is considered as a public health problem in the world. Totally, 5% of the world population, especially in Asia and Africa suffer from this problem. The prevalence of acute hepatitis in America is 0.1-0.2 percent, 50% of those with hepatitis C (HCV) and 5-10% of them with hepatitis B (HCV) develop chronic hepatitis. Determining HBV and HCV genotypes is important to...

Acute viral hepatitis is the most common cause of jaundice in pregnancy. The course of most viral hepatitis infections (e.g., hepatitis A, B, C and D) is unaffected by pregnancy, however, a more severe course of viral hepatitis in pregnancy has been observed in patients with hepatitis E. Notwithstanding, opinions differ over the maternal and fetal outcome of pregnancy associated with viral hepa...

More than two billion people have been infected with hepatitis B virus (HBV), 360 million have chronic infection and 600,000 die each year from HBV-related liver disease or hepatocellular carcinoma. Each year more than 66,000 health professionals are infected by hepatitis b virus and vaccination against hepatitis B saves the life's of these health professionals. The aim of this study was to det...

Hepatitis B virus (HBV), a small and economically packaged double-stranded DNA virus, represents an enormous global health care burden. In spite of an effective vaccine, HBV is endemic in many countries. Chronic hepatitis B (CHB) results in the development of significant clinical outcomes such as liver disease and hepatocellular carcinoma (HCC), which are associated with high mortality rates. H...

background: hepatitis b virus potentially accelerates graft rejection and mortality in renal transplantation population. vaccination of graft candidates without prior immunization against hbv seems essential before transplantation but some candidates of transplantation have not received hbv vaccine at the time of receiving graft. we aimed to evaluate immunogenicity of an enhanced regimen (4 dos...

BACKGROUND AND OBJECTIVE The aim of this study was to investigate the prevalence of occult hepatitis B virus (HBV) infection and the HBV surface (S) gene variants circulating in the South African population after nearly two decades of universal hepatitis B vaccination. STUDY DESIGN From a previous serosurvey, 201 serum samples with serological evidence of exposure to HBV were identified and t...

context hepatitis b vaccination of hemodialysis patients is performed all over the world. there are also recommendations from world health organizations to vaccinate patients with chronic kidney disease (ckd) prior dialysis commencement, but the implementation of a hepatitis b vaccination program is less common and not well organized. evidence acquisition this review article summarizes data ind...

This study assessed antibody persistence and immune memory to hepatitis B vaccine 20 y after priming with a recombinant hepatitis B virus (HBV) vaccine during infancy. Infants were vaccinated according to a 0, 1, 6 mo schedule with or without simultaneous administration of hepatitis B immunoglobulin (HBIg). Half of the subjects enrolled received an interim booster dose at year 5 (boosted) group...

BACKGROUND & AIMS Hepatitis B virus (HBV) infection is a leading cause of liver diseases. We investigated the efficacy and safety of telbivudine in preventing transmission of HBV from hepatitis B e antigen-positive pregnant women with high viral loads to their infants in an open-label study. METHODS We performed a prospective study of 450 hepatitis B e antigen-positive pregnant women with HBV...

BACKGROUND Limited data are available regarding global hepatitis B virus (HBV)-related morbidity and mortality and potential reduction in disease burden from hepatitis B vaccination. METHODS A model was developed to calculate the age-specific risk of acquiring HBV infection, acute hepatitis B (illness and death), and progression to chronic HBV infection. HBV-related deaths among chronically i...
