Aim: A recently discovered DNA virus (SEN virus) has been assumed to be responsible for posttransfusion hepatitis in humans. Phylogenetic analysis of the SEN virus (SEN-V) has revealed the existence of 8 different genotypes (A-H). SEN-V genotype-H (SENV-H) and SEN-V genotype-D (SENV-D) have been described as most closely associated with post-transfusion hepatitis. So far, it is unclear whether ...

To clarify the influence that a recently identified SEN virus (SENV) has on hepatitis C virus (HCV) response to therapy with interferon plus ribavirin, 2 SENV variants, SENV-D and SENV-H, were studied in 100 patients with chronic hepatitis C; 57 of these patients were positive for SENV-D/H DNA, and there were no differences, in clinicopathological features, between patients with and without SEN...

BACKGROUND The SEN virus (SENV) has been identified as a putative new hepatitis virus. This study was conducted to clarify the clinical significance of SENV infection in patients on haemodialysis. METHODS A total of 189 patients on maintenance haemodialysis and 60 healthy controls were enrolled. Of the 189 patients, 154 were followed up for 2 years. SENV DNA (genotypes D and H) was measured b...

Background: SEN virus (SENV) is the latest virus proposed as a cause of unknown hepatitis cases. Among nine detected genotypes of the virus, genotypes D and H are more frequent in hepatitis cases of unknown origin. The aim of this study was to determine the frequency of SENV-D and SENV-H genotypes in the sera of healthy individuals and hepatitis B and C patients. Methods: Totally, 200 serum sam...

We investigated the characteristics and detection rates of SEN virus (SENV) infection among 100 Turkish patients who had with high alanine aminotransferase (ALT) and aspartate aminotransferase levels but were negative for HBV DNA and HCV RNA and had no history of transfusion. As a control group, we also analyzed 50 healthy individuals who had normal ALT levels, were negative for HBV DNA and HCV...

SEN virus (SENV) is a circular, single stranded DNA virus that has been first characterized in the serum of a human immunodeficiency virus type 1 (HIV-1)-infected patient. Eight genotypes of SENV (A-H) have been identified and further recognized as variants of TT virus (TTV) in the family Circoviridae. Here we describe the first genomic characterization of a SENV isolate (5-A) from South Americ...

BACKGROUND AND PURPOSE SEN virus (SENV) is assumed to be responsible for post-transfusion non-A to -E hepatitis. Phylogenetic analysis of SENV has shown 9 different strains. Two strains, SENV-H and SENV-D, were described as possible candidates for post-transfusion hepatitis. This study examined the prevalence of SENV infection and its clinical importance for patients undergoing hemodialysis. ...

BACKGROUND The SEN virus (SENV) is a prevalent blood borne pathogen that has a worldwide incidence. SENV is comprised of eight genotypes; genotypes H and D are frequently associated with the pathogenesis of non-A - E hepatitis and post-transfusion hepatitis in blood donors and hepatitis patients. So far, no SENV pathogenesis has been reported in the liver biopsies of SENV carriers, but the freq...

background: sen virus (senv) is the latest virus proposed as a cause of unknown hepatitis cases. among nine detected genotypes of the virus, genotypes d and h are more frequent in hepatitis cases of unknown origin. the aim of this study was to determine the frequency of senv-d and senv-h genotypes in the sera of healthy individuals and hepatitis b and c patients. methods: totally, 200 serum sam...
