Role of Hepatitis B Virus Surface Antigen Quantification in E Antigen Negative Chronic Hepatitis B Infection
Background/Aim: Hepatitis B surface antigen(HBsAg) is routinely detected qualitatively in Hepatitis B Virus(HBV) infection where its persistence beyond 6 months defines chronic hepatitis B(CHB) infection. Hepatitis B e antigen (HBeAg) usually indicates active HBV replication and risk of transmission of infection. In spite of the emerging use of chemiluminescence based quantitative HBsAg assays ...
متن کاملHepatitis B virus DNA viral load determination in hepatitis B surface antigen-negative Swiss blood donors.
BACKGROUND Nucleic acid test (NAT) hepatitis B virus (HBV) screening for all blood donations with a sensitivity limit of 25 IU/mL in the individual donation is mandatory in Switzerland since 2009. The aims of the two studies were to define the percentage of antibody to hepatitis B core antigen (anti-HBc) or anti-HBc and antibody to hepatitis B surface antigen (anti-HBs)-positive donors bearing ...
متن کاملHepatitis B virus surface antigen (HBsAg)-positive and HBsAg-negative hepatitis B virus infection among mother-teenager pairs 13 years after neonatal hepatitis B virus vaccination.
It is unclear whether a mother who is negative for hepatitis B virus surface antigen (HBsAg) but positive for hepatitis B virus (HBV) is at potential risk for mother-to-child transmission of HBV. This study, using a paired mother-teenager population, aimed to assess whether maternal HBsAg-negative HBV infection ((hn)HBI) is a significant source of child HBV infection (HBI). A follow-up study wi...
متن کاملMicrovessel density and clinicopathological characteristics in hepatitis C virus and hepatitis B virus related hepatocellular carcinoma.
AIMS To compare intratumorous microvessel density (MVD) and clinicopathological features in two different groups of hepatocellular carcinoma (HCC), namely: hepatitis B virus (HBV) related HCC (B-HCC) and HCV related HCC (C-HCC). METHODS Fifty consecutive cases each of B-HCC and of C-HCC were studied. Microvessel numbers were assessed by staining for the antigen CD34; in each case, three areas...
متن کاملThe Absence of Hepatitis C Virus Infection Among Patients with Hepatitis B virus in Mashhad, Iran
Background and Aims: Many studies have provided evidence for the role of hepatitis B and C viruses in the development of liver cancer. Although the routine treatment is available for both conditions, no definite guideline is available to treat patients dually infected with HBV and HCV. This study was performed to determine the frequency of HBV/HCV-coinfection in Mashhad, North-East of Iran. Mat...
