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 Ira...

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 functional renal impairment in diseases caused by hcv was more important than in diseases caused by hbv. the egfr was statistically lower in cirrhosis secondary to hcv than in hcv chronic hepatitis. results hbv chronic hepatitis, hcv chronic hepatitis, and cirrhosis secondary to these viruses were associated with a reduction of the gfr. the egfr was higher in patients with hbv chron...

results of 351 patients, 76 patients (group 1) had a strong positive result for salivary occult blood test and 275 patients (group 2) had weak positive or negative test results. significant factors between the groups were obesity, level of ast, alt, ldh, alp, alb, d.bil, t.cho, afp, platelets (plt), iri, homa-ir, current interferon (ifn) treatment and the daily frequency of tooth brushing. betw...

introduction: blood derived products have been known as an effective treatment for many years. however, this treatment is not without risk of infections transmission including hepatitis b virus (hbv) and hepatitis c virus (hcv) and human immune-deficiency virus (hiv) in people who received the blood. nevertheless, due to a high risk of blood born diseases through blood transfusion, screening fo...

Background and Aims: Viral hepatitis is a global health problem with a high mortality rate. Recently, a new Flavi-like virus, provisionally named hepatitis G virus (HGV), has been described. HGV does not induce an immune response that is consistently detectable by using recombinant proteins from prokaryotic expression, therefore studies have been conducted by using polymerase chain reaction (...

context hepatitis b virus (hbv) and hepatitis c virus (hcv) infections constitute a major global health problem. about 60,000 and 350,000 deaths occur as the results of hbv and hcv infections, respectively. chronic hepatitis b and c infections are leading causes of cirrhosis and hepatocellular carcinoma (hcc) which are considered as the third cancer-associated cause of deaths worldwide. iran su...

background the transmission of hepatitis b virus (hbv) is parenteral, sexual and prenatal. prevention of vertical transmission of hbv is extremely important, because hbv infection in early life usually results in a chronic carrier state. there has been so much debate about hepatitis b surface antigen (hbsag) screening in pregnant women. objectives the aim of this study was to determine the prev...
