conclusions in conclusion, the prevalence of hbv infection was low in the south of iran, but genotype d represented the major hbv genotype in this population. among the variables, age, duration of hd, history of blood transfusion, and using shared hd devices influenced the prevalence of hbv among hd patients. results both kinds of assay determined that nine (5.88%) patients were hbv positive (h...

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...

Hepatitis B virus (HBV) reactivation after chemotherapy or immunosuppressive therapy is a serious cause of liver-related morbidity and mortality. The mechanism of HBV reactivation is still unclear, but it is believed due to the suppression of immune response hence increasing the viral load. No uniform diagnostic criteria are available, HBV reactivation can be confirmed by an increase in serum H...

conclusions a high rate of 25% and 24.13% of hbv dna was detected among patients with hodgkin and non-hodgkin lymphoma, respectively. results three out of 12 (25%) hodgkin samples and seven out of 29 (24.13%) non-hodgkin showed positive hbv dna results. the results of sequencing revealed that the d genotype was predominant among the positive hbv patients. interestingly an unpredictable amino ac...

Hepatitis B virus(HBV) infection remains a global problem, despite the effectiveness of the Hepatitis B vaccine in preventing infection. The resolution of Hepatitis B virus infection has been believed to be attributable to virus-specific immunity. In vivo direct evaluation of anti-HBV immunity in the liver is currently not possible. We have developed a new assay system that detects HBV clearanc...

chronic hepatitis b is still a major public health issue despite the successful prophylactic vaccination attempts. chronicity of hepatitis b virus(hbv) is mainly due to its ability to debilitate host's immune system. therefore, major measures have been taken to stop this process and help patients with chronic hepatitis b infection recover from their illness. while satisfactory results have...

abstract one of the best reliable markers of hepatitis b virus infection is antibodies to the core antigen (anti-hbc). a first-time blood donor with hbsag positivity was identified as an hbv carrier that was anti-hbc negative. the patient was followed for 24 months in order to investigate the evolution of his hbv serological profiles and hbvdna (pcr). in the follow-up for 24 months, hbsag, hbea...

Hepatitis B virus (HBV) infection is a major cause of morbidity and mortality in human immunodeficiency virus (HIV)-infected patients worldwide. It is unclear whether HIV-related outcomes are affected by HBV coinfection. We compared virological suppression and immunological recovery during antiretroviral therapy (ART) of patients of different HBV serological status in the Swiss HIV Cohort Study...
