Liver disease, particularly viral hepatitis, is increasingly common. The most frequent causes of long-term, or chronic, viral hepatitis are persistent infections with the hepatitis B or hepatitis C virus. Worldwide, 400 million people are chronic carriers of the hepatitis B virus [1]. Each year, between 500,000 to 1.2 million people die from progression of this viral infection, making it the 10...

results liver function tests in the healthy blood donors were within the normal range. the incidence rates of senv-d and senv-h in the 184 total blood donors were 10 (5.4%) (95% confidence interval (ci): 2.1% - 9.0%) and 32 (17.4%) cases (95% ci: 12.0% - 23.0%), respectively. senv-h/d co-infection occurred in 2 (1.1%) patients. the sera of 8/184 (4.3%) were positive for anti-hbc antibody but ne...

abstract background: investigators were suspicious of tyrosine-methionine-aspartate-aspartate (ymdd) mutations occurred only in patients who were treated by lamivudine. however, ymdd mutations of hepatitis b virus gene (hbv dna) in patients with chronic hepatitis b (chb) untreated with antiviral medicines was reported in some studies. the aim of this study was to evaluate ymdd mutations in iran...

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...

conclusions the palestinian and israeli official policies to give a booster dose for risk groups like medical students at anti-hbs level below 10 miu/ml should continue to ensure absolute protection. the currently-used vaccine and its time program cleared virus from students believed to have been exposed to the virus during their lifetime. background hepatitis b infection is a global public hea...
