Although an estimated 1 million persons in the United States are chronically infected with hepatitis B virus, the prevalence of hepatitis B has declined since the implementation of a national vaccination program. Hepatitis B virus is transmitted in blood and secretions. Acute infection may cause nonspecific symptoms, such as fatigue, poor appetite, nausea, vomiting, abdominal pain, low-grade fe...

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 transfusion...

results findings showed that the genotype -607a/a is associated with the susceptibility to chronic hepatitis b. furthermore, allele c at position -137 is suggested to play a protective role against development of chronic hbv infection. conclusions host genetic factors play an important role in determining the outcome of hbv infection. it is suggested that il-18 genotype -607 a/a is associated w...

Hepatitis B virus (HBV) and hepatitis C (HCV) infections remain a significant health burden in the world, which is mainly attributed to patients who develop chronic hepatitis, liver cirrhosis, hepatocellular carcinoma (HCC). The epidemiology of Surakarta, Central Java Province, Indonesia has never been reported. This study aimed investigate demographic, clinical, laboratory characteristics with...

conclusions fulminant hepatitis b is associated with distinct mutational patterns of hbv, underlining that genomic diversity of the virus is an important factor determining its pathogenicity. results the most commonly detected diversities affect regulatory motifs of hbv in the core and s region, indicating that these alterations may convert the virus to an aggressive strain. moreover, mutations...

BACKGROUND Worldwide 2 billion people are exposed to hepatitis B infection, 350 million have chronic infection, 65 million in sub-Saharan Africa. Uganda is highly endemic with 10% national prevalence of hepatitis B infection, rates varying across the country from 4% in the southwest and 25% in the Northeast. Childhood vaccination was rolled out in 2002, the effect of which on the burden of hepa...

BACKGROUND Occult hepatitis B infections are becoming a major global threat, but the available data on its prevalence in various parts of the world are often divergent. OBJECTIVE This study aimed to detect occult hepatitis B virus in hepatitis B surface antigen-negative serum using anti-HBc as a marker of previous infection. PATIENT AND METHODS A total of 1000 randomly selected hepatitis B ...

800x600 hepatitis b virus (hbv) infection is the main cause of chronic hepatitis, cirrhosis and hepatocellular carcinoma (hcc). several factors such as serum hbv dna level, genotype and specific viral mutations have been clarified to determine disease progression of chronic hepatitis b. among these, mutations can also occur in chronic hbv patients with antiviral treatment such as lamivudine the...
