Data on prevalence of hepatitis E virus (HEV) in Malawi is limited. We tested blood samples from HIV-uninfected and -infected populations of women and men enrolled in research studies in Malawi during 1989-2008 to determine the seroprevalence of HEV, hepatitis A virus (HAV), hepatitis B virus (HBV), and hepatitis C virus (HCV). Samples were tested for IgG against HEV, total antibodies against H...

Thirty male patients (28 homosexual or bisexual) with biopsy proven chronic active hepatitis B were randomised to receive lymphoblastoid interferon (Wellferon) or no treatment. All patients were HBeAg-positive and had continuing viral replication. Interferon was given as a single daily i.m. injection for 28 days at a starting dose of 2.5 megaunits/m2 increasing to a maximum of 7.5 megaunits/m2/...

Serum hepatitis B virus (HBV) DNA level is a predictor of the development of cirrhosis and hepatocellular carcinoma in chronic hepatitis B patients. Nevertheless, the distribution of viral load levels in chronic HBV patients in Brazil has yet to be described. This cross-sectional study included 564 participants selected in nine Brazilian cities located in four of the five regions of the country...

BACKGROUND/AIMS Whether alcohol intake increases the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B virus (HBV) infection remains controversial. The aim of this study was to determine the effect of alcohol intake on the development of HCC. METHODS Between January 2006 and August 2008, 146 patients with an initial diagnosis of HCC who were hospitalized in 3 major h...

HepG2.2.15 cell is a widely used cell model for studying HBV (hepatitis B virus) in vitro. In these cells, the HBV genome is integrated in several sites of HepG2 cellular DNA. These multiple copies may have some influence on the cellular processes. We constructed a new plasmid, pSEH-Flag-HBV, and transfected it into HepG2 cells, and then screened it with hygromycin. We then used ELISA, PC...

Hepatitis B virus (HBV) DNA was extracted from sera of six carriers with hepatitis B e antigen as well as antibody to hepatitis B surface antigen and sequenced within the pre-S regions and the S gene. HBV DNA clones from five of these carriers had point mutations in the S gene, resulting in conversion from Ile-126 or Thr-126 of the wild-type virus to Ser-126 or Asn-126 in three carriers and con...

T cells recogttize speciftc antigens through the T celL receptor (TCR) and self M HC nolecules. Structural variation in the TCR to recognise the enonnous diversity, of antigens is effected b), naturation rearrange,nent of TCR genes in a tilaruter analogous to inrnunoglobulin genes. Although it is believed that T cells play a uajor role in the seroconversiotr of e Ag positive hepatitis B caliers...

AIM To investigate the long-term outcome and the risk of progression to chronic hepatitis B in inactive hepatitis B surface antigen carriers. MATERIAL AND METHODS A total of 307 HBsAg (+)/HBeAg (-)/antiHBe (+) subjects with initially normal alanine aminotransferase (ALT) levels and undetectable/ low serum HBVDNA with hybridization assay and later with PCR (10(5) copies/ml), were followed-up e...

We read with great interest the article by Ding et al.,1 “Mutations in the S gene and in the overlapping reverse transcriptase region in chronic hepatitis B Chinese patients with coexistence of HBsAg and anti-HBs”. We would like to specify some additional issues related to the coexistence of HBsAg and antiHBs in a summary. The rate of simultaneous HBsAg and anti-HBs serological profile ranged f...
