childhood hepatitis b virus (hbv) infection causes both medical and public health challenges. infants who acquire hbv parentally have up to 90% risk of developing chronic hbv infection. it is now estimated that approximately 10% of worldwide cancers are attributable to viral infection, with the vast majority (>85 %) occurring in the developing world. in this distribution, elevated rate and prev...
conclusions these results suggest that polymorphisms in interleukin-10 gene promoter influence clinical outcome of hbv infection and susceptibility to hbv infection. results persistent hbv infection was associated with il-10-1082 ag (p = 0.001) and gg (p = 0.004) genotypes and g (p = 0.000) allele. il-10-819 t/c and -592 a/c genotype and allele frequencies did not show any correlation with the ...
Despite the availability of an effective vaccine, hepatitis B virus (HBV) infection remains a major health problem. HBV e antigen (HBeAg)-negative strains have become prevalent. Previously, no animal model mimicked the clinical course of HBeAg-negative HBV infection. To establish an HBeAg-negative HBV infection model, the 3.2-kb full-length genome of HBeAg-negative HBV was cloned from a clinica...
background the occult hepatitis b infection (obi) is defined as the presence of hepatitis b virus (hbv) dna in the sera or in the liver biopsy and the absence of hepatitis b surface antigen (hbsag) by serological test. objectives the current study aimed to evaluate the occult hbv infection by polymerase chain reaction (pcr) and determine hbv genotyping among the patients with abnormal alanine t...
Greenland remains a highly endemic area for hepatitis B virus (HBV) infection. This is in sharp contrast to other modern societies, such as Denmark. To address this discrepancy, we investigated the natural history of HBV infection in Greenland by estimating the age-specific incidence of HBV infection, the proportion of chronic carriers, and the rates of hepatitis B surface antigen seroclearance...
BACKGROUND Data on prevalence and incidence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection in Rwanda are scarce. METHODS HBV status was assessed at baseline and Month 12, and anti-HCV antibodies at baseline, in a prospective cohort study of HIV-infected patients in Kigali, Rwanda: 104 men and 114 women initiating antiretroviral therapy (ART) at baseline, and 200 women not ye...
BACKGROUND Hepatitis B virus (HBV) and tuberculosis (TB) represent major public health problems. There is currently little data on HBV infection among TB patients with and without human immunodeficiency virus (HIV). OBJECTIVES To assess HBV prevalence among TB patients with and without HIV. STUDY DESIGN From April 2008 to March 2010, a cross-sectional study was conduct among TB patients att...
Background: HBV and HCV infection, have been found to worsen the health of PLWAS, thereby impairing treatments management. HIV, HBV, are transmitted through similar routes hence presence infection with any them could be a risk factor for others. Objective: Determine prevalence HBV/HCV co-infection in persons HIV. Method: This was serological study For Hepatitis B surface antigen investigated an...
BACKGROUND Accurate and personalized molecular virological diagnosis of hepatitis B virus (HBV) infection is crucial for individualized selection of patients for antiviral therapy in Romania. OBJECTIVES We aimed to investigate HBV mutations in Romanian patients with chronic HBV infection, also to match HBV genotypes with HBV mutations identified and clinical outcomes. PATIENTS AND METHODS T...
BACKGROUND Neither HBV DNA nor HBsAg positivity at birth is an accurate marker for HBV infection of infants. No data is available for continuous changes of HBV markers in newborns to HBsAg(+) mothers. This prospective, multi-centers study aims at observing the dynamic changes of HBV markers and exploring an early diagnostic marker for mother-infant infection. METHODS One hundred forty-eight H...
