BACKGROUND AND AIMS Currently, vaccination is the most effective protective tool against hepatitis B virus infection. Some studies have shown that positive results for a hepatitis B virus surface antigen (HBsAg) test may be seen after vaccination. MATERIALS AND METHODS In this clinical trial study, 62 healthy adult volunteers were randomly assigned to receive either the Engerix-B or the Hepav...

OBJECTIVES This analysis examined the incidence rate of chronic arthritis adverse reactions reported following adult rubella and hepatitis B vaccinations. In this analysis, etiologic mechanisms for chronic arthritis following adult rubella and hepatitis B vaccines were also explored. METHODS The Vaccine Adverse Events Reporting System (VAERS) database was analyzed for the incidence rate of re...

The authors report a patient who developed systemic polyarteritis nodosa two months after hepatitis B vaccination and review the literature concerning this vaccination and the development of autoimmune conditions, mainly vasculitis. A 14-year-old boy who had no relevant previous history and who was not taking any drugs presented with a livedo reticularis, fever, loss of weight, testicular pain,...

Hepatitis B virus (HBV) infection is one of the major public health problems in the world (1). About 350 to 400 million people are chronically infected with hepatitis B worldwide. Originally known as ‘serum hepatitis’ (2), t...

Background and Objectives: Vaccination is the major strategy to protect nurses against infection with hepatitis B virus. However, some nurses do not produce sufficient amount of anti-HBsAg antibody required for immunity against infection. Chronic occupational stress has been proposed as a risk factor to humoral immunity. Given that nursing staff is exposed to occupational stress risk, this stud...

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 vaccination is mandatory for all hepatitis B surface antigen (HBsAg)-negative hemodialysis (HD) patients with low hepatitis B surface antibody titers. We report a case of transient hepatitis B surface antigenemia, detected incidentally, in an HD patient after the second dose of Hepatitis B vaccine. The patient had to be isolated on a separate HD machine, in a separate room, until fu...

conclusions hepatitis b core antibody immunoglobulin m positivity is different in healthy blood donors of different countries according to the prevalence of chronic hepatitis b and its vaccination. based on the current study findings, all positive samples of hepatitis b core antibody in iranian blood banks should be considered as candidates for occult hepatitis b not just the window period infe...
