In order to determine the efficacy of recombinant hepatitis B vaccine in Iranian infants, we analyzed the efficacy of a recombinant hepatitis B vaccine in 115 infants aged 12-24 months born to HBsAg negative mothers who received three doses of HBV Antibody to hepatitis B surface antigen (anti-HBs) was checked after the third dose of the vaccine, 94.8% of the infants had developed protective...

The highest prevalence rates of hepatitis C virus infection in the world have been recently reported among Egyptian blood donors and frequent recipients of transfusions and other blood products. This is the first report, however, demonstrating hepatitis C as the most frequent association with chronic liver disease in Egypt. Of 1023 patients referred to the Liver Institute in Menoufia governorat...

background hepatitis b virus (hbv) infection is a major public health problem that affects billions of people worldwide. the lack of information on hbv prevalence among the general population is an obstacle to formulate effective policies to reduce the burden of viral hepatitis. objectives this population based serological survey was conducted in kermanshah province to determine the local preva...

A critical first step in a "rational vaccine design" approach for hepatitis C virus (HCV) is to identify the most relevant mechanisms of immune protection. Emerging evidence provides support for a protective role of virus neutralizing antibodies, and the ability of the B cell response to modify the course of acute HCV infection. This has been made possible by the development of in vitro cell cu...

Background Occult hepatitis B infection (OBI) is considered a risk factor for progression of liver disease in patients with hepatitis B virus (HBV) infection. This disease progression is reported to be more significant in those with concomitant HIV infection. We aimed to determine the prevalence rate of OBI in a sample of HIV-positive patients. Materials and Methods: Sixty-six HIV-infected pati...

BACKGROUND No study has compared the long-term prognoses of hepatitis C patients with hepatitis C virus (HCV) antibody-negative individuals and investigated the effects of interferon (IFN) treatment. To clarify the long-term prognosis of HCV-positive residents of an isolated Japanese island and prospectively investigate the effects of IFN treatment in comparison with the HCV-negative general po...

Abstract Background There is a decrease in vaccine-specific antibody to certain vaccine-preventable diseases in children after chemotherapy, but the frequency of non-immune patients is not clear. In the present case-control study, was taken under investigation protection level to Hepatitis B infection in children 6 months after completing chemotherapy. Materials and Methods In this study 6...

hepatitis b virus (hbv) infection is the 10th leading cause of death worldwide. the most important diagnostic and screening marker for hbv infection is hepatitis b surface antigen (hbsag), and the most widely used hbsag screening test is enzyme-linked immunosorbent assay (elisa). in this study, an elisa assay has been developed for detection of hbsag using two novel monoclonal antibodies (mab) ...

We analyze the case of a 49-year-old male patient who presented with clinical signs acute hepatitis an initial suspicion autoimmune etiology. Laboratory findings demonstrated positive antinuclear antibody, anti-smooth muscle antibody and high serum gamma globulin. Histology liver biopsy revealed changes compatible hepatitis, which associated International Autoimmune Hepatitis Group score 7, det...
