OBJECTIVE To determine whether prolonged infection with hepatitis B virus is associated with a lower blood cholesterol concentration. DESIGN Cross sectional study. SETTING 81 villages in rural China with a high prevalence of chronic infection with hepatitis B virus. SUBJECTS 1556 apparently healthy men aged 35-64 years, randomly selected. MAIN OUTCOME MEASURES Hepatitis B virus carrier ...
The purpose of this study was to evaluate the influence of hepatitis B vaccination on the results of surface antigen tests in blood donors. In this research, eighteen non-immunized volunteers (ten male, eight female) aged 21 to 58 years received 20 ug of the recombinant B vaccine (Heberbiovac-HB) intramuscularly. Blood samples were drawn from all volunteers before the first vaccine dose (day 0)...
A 72-year-old female negative for hepatitis B surface antigen (HBsAg) and positive for antibody to hepatitis B surface antigen (anti-HBs) was diagnosed to have follicular lymphoma in 2006. Seventeen cycles of rituximab-based chemotherapy were administered over 23 months. Twelve days after the last cycle of chemotherapy, serum aminotransferase levels were elevated, and hepatitis serology tests r...
Five nonoverlapping antigenic sites (sites I through V) of woodchuck hepatitis virus surface antigen were identified with competitive binding assays involving monoclonal antibodies. Site I contributed to cross-reactions among surface antigens of hepatitis B-like viruses infecting woodchucks, ground squirrels, and humans. At least three distinct sites (sites I, II, and III) are responsible for c...
Abstract Background and objectives: Hepatitis B virus infection is a major health problem in worldwide. The prevalence of Occult and chronic HBV in hemodialysis patients is higher than standard in developing countries. People with occult HBV are negative for HBV surface antigen (HBsAg) but positive for HBV-DNA. We aimed to evaluate occult hepatitis B infection in patients under hemodialysis in ...
Background: Despite of effective vaccineand impressive treatment, number cases hepatitis b virus rising dayby day. The reasons include low antibody titre in blood after vaccination, needle stick injury medical personnel,lack awareness general public about the mode transmissions and prevention. Also treatment part isexpensive monitored by repeated viral load envelope antigen estimation.We are co...
BACKGROUND AND OBJECTIVES Perinatal exposure is an important mode of hepatitis B virus (HBV) transmission, resulting in chronic disease in ∼ 90% of infected infants. Immunoprophylaxis recommended for infants born to hepatitis B surface antigen-positive mothers reduces up to 95% of perinatal HBV infections. We sought to identify factors associated with perinatal HBV transmission. METHODS We an...
Two patients presented with positive hepatitis B virus antigen reactivity. Both the patients had medical records indicating clinical and biochemical manifestations of viral hepatitis. Treatment with coenzyme Q10 and w-3 fatty acids was associated with reversal of antigenicity causing negative hepatitis B antigen reactivity.
