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...
Introduction and objective: Hepatitis B virus (HBV) is a member of Hepadnaviridae and a major causative agent of chronic and acute hepatitis, liver cirrhosis and hepatocellular carcinoma. Genotype determination of HBV is based on PCR-RFLP and sequencing of genome of the virus. The genotype formation is mainly due to mutations of HBV precore, S, and YMDD (tyrosine-methionine-aspartate-aspartate ...
conclusions the significant number of coinfected hiv-hcv patients only had hbcab positive test without detectable hbv-dna. further studies for detection of hbv-dna in both serum and liver biopsy specimens may help clarify the impact of hbv infection in coinfected hiv/hcv patients. results of 103 hiv-hcv coinfected patients, both hbsag and hbcab were positive in 7 patients (6.8%), negative in 44...
background occult hepatitis b virus infection (obi) is defined as the presence of hepatitis b virus (hbv) dna in the liver and/or in the serum of patients with negative results of hepatitis b s antigen (hbsag) test with or without serological markers of previous viral exposure. the impact of obi in patients with chronic hepatitis c (chc) is still unclear. objectives the aim of this study was to...
Recovery from an acute hepatitis B virus (HBV) infection is associated with loss of HBV DNA from serum, hepatitis B e antigen seroconversion, hepatitis B surface antigen (HBsAg) seroconversion, and normalization of serum aminotransferases. These changes generally imply clearance of virus, but clinical observations have shown that reactivation of HBV infection can occur either spontaneously or a...
conclusions in comparison with the rate of hbcab positivity reported in other iranian studies, the rate was higher in the present study. there were a few variations, genotypes, and subtypes among the infected injecting drug users. further investigations are needed to unravel the molecular characterization of obi. results sixty-four (28%) participants were hbcab positive, 59 cases were hbcab pos...
Chronic hepatitis C virus (HCV) infection combined with occult hepatitis B virus (HBV) infection has been associated with increased risk of hepatitis, cirrhosis and hepatocellular carcinoma. This study aimed to determine the prevalence of occult HBV infection among Egyptian chronic HCV patients, the genotype and occurrence of surface gene mutations of HBV and the impact of co-infection on early...
