Background: HIV infected persons are also at risk for Infection with other pathogens, like Hepatitis B virus (HBV) and Hepatitis C virus (HCV). One of the main steps in the planning of treatment and prevention is the study of the HIV positive population who have HBV and/or HCV infection. The objective of this study was to determine the prevalence of HIV and Hepatitis B and C dual infection in ...

conclusions hepatitis b core antibody immunoglobulin m positivity is different in healthy blood donors of different countries according to the prevalence of chronic hepatitis b and its vaccination. based on the current study findings, all positive samples of hepatitis b core antibody in iranian blood banks should be considered as candidates for occult hepatitis b not just the window period infe...

Background: Although regular frequent blood transfusion improves overall survival of multi-transfused patients like β-thalassemic ones, it carries a definite risk of infection with blood-borne viruses such as viral hepatitis. This study was done to determine seropositivity of hepatitis B virus (HBV), hepatitis C virus (HCV), and Human Immunedeficiency Virus (HIV) infections among β-th...

abstract background: hepatitis b virus (hbv) infection in patients who lack detectable hepatitis b surface antigen (hbsag) is called occult hepatitis b infection. such infections have been frequently identified in patients with chronic hepatitis cliver disease, but their prevalence is not known. methods: 207 patients with chronic hepatitis c who were hcv -rna and antihcv positive were studied f...

During past decades, the association between type of blood group (ABO) and hepatitis B and C virus has always been discussed. This study was designed to investigate the possible association between type of ABO blood group and chronic hepatitis B and C infection. Methods: In the present analytical stud...

diagnosis of hepatitis b is routinely based on of serological assay of hepatitis b surface antigen (hbsag). occult hepatitis b virus (hbv) infection is generally defined as the detection of hbv -dna in the serum or tissues of subjects who have negative test for hbsag. transmission of hbv infection has been documented from hbsag negative, anti-hbc positive blood and organ donors. the aim of this...
