conclusions a significant direct correlation was observed between the viral dna copies present in patients’ cerumen and serum. however, the correlation between saliva viral load with serum and cerumen viral load was very low and inverse. these findings suggest that the presence of the hepatitis b virus (hbv) in non-invasive specimens (such as cerumen and saliva) should also be evaluated when mo...

Background: Hepatitis B surface antigen (HBsAg) is one of the main proteins of HBV envelop and its serum quantitative measurement is the most common quantitative test for monitoring the progress of Chronic Hepatitis B. Although measurement of serum HBV DNA copy number is a gold standard method for displaying viral load, the test is relatively expensive and it is not readily available everywhere...

Introduction: Occurrence of detectable amounts of viral antigen or viral particles in the blood of infected patients with Hepatitis B virus (HBV) is a significant characteristic of HBV infection. Detection of HBV antigen or its DNA among individuals of a community is a crucial factor to know the burden of HBV infection. Hepatitis B surface antigen (HBsAg) is a suitable marker of HBV infection b...

Introduction: Hepatitis B virus (HBV) infection is a global public health problem. Serum HBV DNA measurement is a non-invasive test that predicts the liver disease progression. The aim of this study was to determine the HBV DNA level and look for a relation between the HBV DNA level and liver histology. Methods: This was a cross sectional study on chronic...

Introduction: The hepatitis B is a viral infection that causes a big problem globally. About 2 billion people worldwide are infected and there are now about 400 million HBV-DNA carriers around the world. HBV infection is the ninth cause of death worldwide and infects about 350 million new cases each year in the world. HBV-DNA can be spotted in different body secretions and fluids, including se...

background to evaluate the strength of association and to determine the best prediction of response in terms of sensitivity and specificity among quantitative baseline hbv-dna levels in blood serum in patients with chronic hepatitis b (chb) infection who treated with interferon-alpha-2b. patients and methods totally, 78 chb patients with serum hbv-dna>105 copies/ml were treated with interferona...

background oxidative stress plays a major pathogenic role in liver injury following chronic hepatitis b. glutathione peroxidase (gpx) has a central role in regulating the oxidative state. hepatitis b virus (hbv) results in down-regulation of gpx. on the other hand, iron homeostasis is disrupted in hbv infected patients. therefore, the objective of this study was to assess the interplay of gpx a...

BACKGROUND Serum hepatitis B virus (HBV) DNA and hepatitis B e antigen (HBeAg) liver function in patients with chronic hepatitis B (CHB) are significantly associated. A comparison of clinical significance of fecal HBV DNA and serum HBV DNA has not yet been reported. MATERIAL AND METHODS Stool and serum samples were collected from 66 patients with CHB. Fecal HBV DNA, serum HBV DNA, and intestina...
