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 (...

background and aims: lamivudine is amongst the antiviral for drug chronic hepatitis b treatment. during therapy with lamivudine, variants may emerge with ymdd mutation in the reverse transcriptase (rt) region of polymerase gene. this mutation might have a role in drug resistant for hbv. materials and methods: hbv dna extraction from serum sample of 88 patients, were subjected to nested pcr for ...

the aim of this study was to investigate the prevalence of hepatitis b virus (hbv) genotypes in isparta, southwest of turkey, as well as the clinical features and transmission route for patients with hbv infections. methods: patients (n = 135) with hbv infection were included in the study. epidemiological and clinical data were obtained. hbv genotypes were determined with a pres2 epitope elisa ...

 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...

Background: Blood transfusion plays a great role in public health and the blood safety still has remained a main concern. HBV has been considered as one of the most prevalent blood borne infections. It is estimated that chronic HBV affects 350-400 million people worldwide. Comprehensive knowledge about HBV has high importance in Iran due to high number of blood dependent patients. Material ...

Background: Recently, some new viruses have been identified for their association with hepatitis which Torque Teno Mini Virus being among them. The aim of this study was to determine the frequency of Torque Teno Mini Virus in healthy individuals and hepatitis B and C patients in Isfahan, Iran. Materials and Methods: One hundred serum samples of healthy individuals from Isfahan Blood Transfusi...

Background and Aims: Hepatitis D virus (HDV) can infect human population either as a superinfection or concurrent hepatitis B virus (HBV) infection. It is expected that presence of HDV infection is more prevalent in endemic HBV areas. Overall 5% of Iranian general populations are chronic HBV carriers. The aim of this study was to determine the seroprevalence of HDV and its clinical impact in ...

With up to 400 million affected people worldwide, chronic hepatitis B virus (HBV) infection is still a major health care problem. During the last decade, several novel therapeutic approaches have been developed and evaluated. In most regions of the world, interferon-α (IFN-α), and nucleos(t)ide analogues are currently approved. Despite major improvements, none of the existing therapies is optim...

Background: Direct-acting antiviral agents (DAAs) are used increasingly to treat hepatitis C virus (HCV) infection. Reports were published recently on hepatitis B virus (HBV) reactivation (HBV-R) in patients with HBV–HCV co-infection. Hepatitis B virus reactivation, defined as an abrupt increase in HBV replication in patients with inactive or resolved HBV infection, may result in clinically sig...
