HYPOTHESIS Hepatic allografts from donors positive for antibody to hepatitis B core antigen (anti-HBc) frequently transmit hepatitis B virus (HBV) infection to recipients. Therefore, most transplantation centers will not use these organs for orthotopic liver transplantation (OLT). Although it is expensive and not always efficacious, hepatitis B immune globulin (HBIG) has been used routinely for...

BACKGROUND Occult HBV infection (OBI) is defined by the persistence of HBV in the liver without serum HBsAg and HBVDNA. It represents a life-threatening event during immunosuppressive chemotherapies. An OBI occurs in approximately 18% of HBcAb + patients. International guidelines suggest surveillance for HBV markers in immunosuppressed patients. In Non-Hodgkin Lymphoma (NHL), the prevalence of ...

We determined the seroprevalence of hepatitis B in Nahavand in a sample of 1824 subjects > 5 years in 2002. Face-to-face interviews were conducted and blood samples taken. The association between risk factor and hepatitis B was assessed using logistic regression. The prevalence of HBsAg positive cases was 2.3%, and HBcAb and HBsAb were isolated in 7.8% and 11.6% of the participants respectively...

Abstract Background and Aims Hepatitis B virus (HBV) reactivation in kidney transplant recipients may be associated with liver failure graft loss, especially anti-HBc antibody (HBcAb)-positive HBs antigen (HBsAg)-negative patients. Belatacept, a selective costimulation blocker, has been used transplantation for some time of other viruses as BK or CMV. However, there are few data on HBV among tr...

To better understand the spread of hepatitis C virus (HCV) infection, we studied the association of HCV infection with similarly transmissible hepatitis B virus (HBV) infection and with hepatitis A virus (HAV) infection, which is supposed to be related to a nosocomial transmission of HCV. This was done by studying the presence or absence of antibodies to these viruses, as well as hepatitis B su...

An epidemiological study of hepatitis viruses type B (HBV) and type C (HCV) and human T-cell leukemia virus type I (HTLV-I) was carried out among 103 residents (male:female=61:42) regarded as Sherpas, at Lukla (Solukhumbu district), Nepal in 2004. Blood was drawn from apparently healthy volunteers at ages of 28.8+12.3 (range 15-66) years. HBsAg, HBsAb, HBcAb, and HCV Ab were measured by micropa...

BACKGROUND Hepatitis B virus (HBV) infection is a major risk factor of cirrhosis and hepatocellular carcinoma affecting billions of people globally. Since information on its prevalence in general population is mandatory for formulating effective policies, this population based serological survey was conducted in Sistan and Baluchistan, where no previous epidemiological data were available. ME...

BACKGROUND In surface antigen of hepatitis B virus (HBsAg)-positive carrier for anticancer treatment of malignant lymphoma, it is well recognized that reactivation of hepatitis B virus (HBV) occasionally occurs. However, there have been only a few studies of HBV reactivation in serum HBsAg-negative and hepatitis B core antigen (HBcAb)-positive occult HBV carriers. We looked at both retrospectiv...

Background: HBV and HCV coinfection is common, particularly in endemic areas and among high risk groups. In this study we have investigated the prevalence of HBV/HCV coinfection and compared the biochemical and serological characteristics of such patients compare with the patients having hepatitis C infection alone. Methods: We studied 207 patients diagnosed as having chronic hepatitis C, with ...

Background Hepatitis B virus (HBV) infection is a public health problem. The lack of information about the seroprevalence and risk factors is an obstacle for preventive public health plans to reduce the burden of viral hepatitis. Therefore, this study was conducted in Iraq, where no studies had been performed to determine the prevalence and risk factors of HBV infection. Methods Blood samples...
