background: the outcome of hepatitis b virus (hbv) infection is chronic or resolved hbv infection. over the time, the levels of hbsag or anti-hbs declined and were not detectable in their sera and was named as isolated anti-hbc. the purpose of this study was to assess the prevalence of isolated anti-hbc in previously hbv infected individuals.methods: from april 2000 to september 2008, the resul...

Background: The outcome of Hepatitis B virus (HBV) infection is chronic or resolved HBV infection. Over the time, the levels of HBsAg or Anti-HBs declined and were not detectable in their sera and was named as isolated anti-HBc. The purpose of this study was to assess the prevalence of isolated anti-HBc in previously HBV infected individuals.Methods: From April 2000 to September 2008, the resul...

Reactivation of HBV is a well-recognized complication following immunosuppression, also in past HBV infection. Based on scientific literature, antiHBs status in HBsAg negative/anti HBc positive patients undergoing chemotherapy may reduce the risk for HBV reactivation, so antiHBs status should be included in a management alghorithm in patients with past HBV infection prior to starting immunosupp...

BACKGROUND/AIMS The widespread use of cytotoxic chemotherapy and immunosuppressants has resulted in reactivation of hepatitis B virus (HBV) recently becoming an issue. Although rituximab (an anti-CD20 monoclonal antibody) has revolutionized the treatment of lymphoma, recent reports have suggested that rituximab therapy increases the risk of viral-mediated complications, and particularly HBV rea...

BACKGROUND Among the Chinese population of 1.3 billion, there are an estimated 93 million carriers of hepatitis B virus (HBV). Men who have sex with men (MSM) are at increased risk for HBV infection; however, the prevalence of HBV immunization and infection among Chinese MSM remains undetermined. METHODS A cross-sectional survey of 1,114 eligible participants was conducted in Beijing, China. ...

Globally, more than two billion persons have been infected at some time with the hepatitis B virus (HBV), and approximately 3.5 million refugees have chronic HBV infection. The endemicity of HBV varies by region. Because chronic hepatitis B is infectious and persons with chronic infection benefit from treatment, CDC recommends screening for HBV among all refugees who originate in countries wher...

BACKGROUND Haemodialysis patients are at increased risk of exposure to blood borne viruses. To reduce transmission in the UK, all haemodialysis patients are regularly screened, and if susceptible to Hepatitis B virus (HBV) infection, vaccinated. METHODS This retrospective study was undertaken to determine the HBV immune status in a large dialysis cohort and the prevalence of occult HBV infect...

BACKGROUND Data on prevalence and incidence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection in Rwanda are scarce. METHODS HBV status was assessed at baseline and Month 12, and anti-HCV antibodies at baseline, in a prospective cohort study of HIV-infected patients in Kigali, Rwanda: 104 men and 114 women initiating antiretroviral therapy (ART) at baseline, and 200 women not ye...

Serologic assays for HBV are the mainstay diagnostic tools for HBV infection. However, the advent of molecular biology-based techniques has added a new dimension to the diagnosis and treatment of patients with chronic HBV infection. Over the past decade, improvements in molecular technology, permitting detection of as few as 10 copies/mL of HBV DNA in serum have led to redefinitions of chronic ...

Hepatitis B virus (HBV) infection constitutes one of the major global public health problems. Not only India and Nepal, East Asia is fighting with the same. About 30 percent of the world's population has serological evidence of current or past infection with HBV. By virtue of its different stage of presentation in different age groups of patients and the rapid mutation in the virus, the treatme...
