conclusions this study suggests that the il-7 level of chb patients may be related to tfh cells. in chb patients, il-7 possibly increases the level of tfh cells and hbv-specific cellular immune responses and thereby reduces the hbv dna level. background in patients with chronic hepatitis b (chb), the relation of interkeukin-7 (il-7) to either the t follicular helper cells (tfh cells) or to a sp...
This study compared the response to adenine arabinoside 5'-monophosphate (ARA AMP) in 60 patients with chronic hepatitis B according to the pretreatment serum hepatitis B virus DNA concentration. The level of hepatitis B virus replication was defined as low (30 patients) or high (30 patients) when serum hepatitis B virus DNA concentration was below or above 100 pg/ml, respectively. Patients rec...
conclusions it is concluded that most hbeag negative hepatitis b patients with serum hbv dna level of 2000-20000 iu/ml, persistent normal alt concentration, and no or mild liver damage on biopsy can be clinically managed as hbv inactive carriers. results two hundred forty-three hbeag negative hepatitis b patients were stratified into three groups based on to their hbv dna level including group ...
Maternal transmission of hepatitis B virus infection in relation to the hepatitis B e antigen/antibody system and serum hepatitis B virus-DNA were evaluated. Results indicate that hepatitis B virus-DNA analysis can identify hepatitis B serum antigen positive mothers who may transmit infection to their offspring.
dna coding for the core antigen from hepatitis b virus (hbcag) was amplified, cloned and propagated in e. coli. the core protein was expressed in e. coli and the product was readily detected by western blot. this protein can be used as a diagnostic material in serum screening tests. to increase the level of expression of this antigen in bacteria, two plasmids were constructed in which the gene ...
conclusions the palestinian and israeli official policies to give a booster dose for risk groups like medical students at anti-hbs level below 10 miu/ml should continue to ensure absolute protection. the currently-used vaccine and its time program cleared virus from students believed to have been exposed to the virus during their lifetime. background hepatitis b infection is a global public hea...
OBJECTIVE. To serially evaluate the viral kinetics of occult hepatitis B virus infection in lymphoma patients and perform a correlation with clinical outcomes. DESIGN. Case series with 1-year follow-up. SETTING. Regional hospital, Hong Kong. PATIENTS. Consecutive patients who were newly diagnosed to have lymphoma in the hospital between 1 April 2007 and 31 March 2008 were tested for hepatitis B...
Background: Torque teno virus (TTV) was the first human Anelloviridae detected in a Japanese patient with an unknown type of hepatitis in 1997. TTV is by far the first known single-stranded circular DNA virus infecting human. In spite of its widespread nature in human population, its pathogenesis is still unclear. In addition, information regarding TTV infection in Iranian population is limited...
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...
Background: Approximately 600,000 deaths occur every year as a result of the acute and chronic consequences of hepatitis B virus infection. Ten different hepatitis B virus genotypes have been identified with distinct geographical distributions. Different clinical outcomes, including the rate of mutations, development of hepatocellular carcinoma, chronicity, response to treatment, transplantatio...
