OBJECTIVE The risk of transmitting hepatitis B virus from donors who are positive for hepatitis B core antibody but negative for hepatitis B surface antigen has been a major concern in liver transplantation. In the Kingdom of Saudi Arabia the overall prevalence of hepatitis B core antibody among the general population was reported to be very high indeed. The purpose of this study is to establis...
One of the most serious kinds of hepatitis is hepatitis B. This condition is more common than AIDS, and is 100 time more contagious. In Iran the most common cause of acute and chronic hepatitis, liver cirrhosis, and also hepatocellar carcinoma in adults, is hepatitis B. more than two billion people are infected and more than 350 million of individuals are carriers of this virus in the entire wo...
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...
The recent addition of testing volunteer blood donors for antibody to hepatitis B core antigen (anti-HBc) has raised questions not apparent when such testing is applied to hepatitis B (HB) infected patients. The review of published studies, and our own, demonstrates that it is difficult to evaluate false positive results. Some patients appear to lose antibody to hepatitis B surface antigen (ant...
Background: Hepatitis B (HB) is one of the main health problems. Over 400 million people worldwide have been evaluated as infected patients or chronic carriers. Health care workers (HCWs) are of higher risk for infectious diseases including HBV infected patients. This study aims to evaluate the rate of HBS antibody among the HCWs of Shahid Sadoughi Burn hospital in Yazd. Methods: This cross...
Background: Nearly 300 million people worldwide are carriers of the Hepatitis B Virus (HBV). Thalassemia and dialysis patients are of the most important individuals at risk for the virus. Despite vaccination, antibody is reduced and there is a possibility of infection to HBV. This study, examines hepatitis B serologic markers among thalassemia and dialysis patients of Mazandaran province, Iran....
Infection with the delta agent can only occur in the context of coexistent hepatitis B virus infection. We describe a patient in whom the clinical features of acute delta hepatitis developed when seroconversion from hepatitis B surface antigen to antibody had already occurred and diagnosis of recent acute hepatitis B was based on high titre IgM antibody to hepatitis B core antigen. We discuss t...
Fulminant hepatic failure occurred in an 11 week old baby of a Caucasian mother who was hepatitis B surface antigen positive, B e antigen negative, and B e antibody positive. Infants of hepatitis B e antigen positive mothers receive immunoprophylaxis against hepatitis, unlike those born to mothers who are B e antibody positive.
This study assessed the level of vaccine-induced hepatitis B surface antibody that is protective against hepatitis B infection and carriage in The Gambia. Sera from 700 of a cohort of 1041 children vaccinated against hepatitis B in infancy were serially tested for markers of hepatitis B until age 7 years. No absolute level of protection against infection was found, but all children who attained...
To evaluate the immune response to hepatitis B vaccination in stable hemodialysis (HD) patients, a retro-prospective investigation was conducted on 68 HD patients. Participants were vaccinated against hepatitis B virus with an intramuscular hepatitis B vaccination schedule, 40 micrograms at 0, 1, and 6 months. The serum antibody level against hepatitis B surface antigen (HBs) in HD patients was...
