Hepatitis B virus (HBV) infection is a major cause of chronic active hepatitis, cirrhosis, and primary hepatocellular carcinoma, all of which are severe threats to human health. However, current clinical therapies for HBV are limited by potential side effects, toxicity, and drug-resistance. In this study, a cell-penetrating peptide-conjugated peptide nucleic acid (PNA), Tat-PNA-DR, was designed...

The prevalence, incidence and clinical course of viral hepatitis were prospectively determined in consecutive recipients of T-cell depleted hematopoieic stem cell transplants (49 mismatched, 60 matched, mean age 38 years; range 11-65). The prevalence of hepatitis B virus (HBV) was 15.6% and that of hepatitis C virus was 3.7% (HCV). HBV reactivated in one patient. Another developed ex novo acute...

Although safe and effective vaccines for hepatitis B virus (HBV) have been available for nearly three decades, this virus kills at least 600,000 people annually worldwide and remains the leading global cause of chronic hepatitis, cirrhosis, and hepatocellular carcinoma. Because the HBV reverse transcriptase lacks a proofreading function, many HBV genotypes, subgenotypes, mutants, and recombinan...

Hepatitis Delta virus (HDV) is a degenerate RNA virus or virusoid and a satellite of Hepatitis B virus (HBV). Three distinct genotypes are described for HDV; genotype I is distributed worldwide but other genotypes appear to be more restricted geographically. In the present study, an RT-nested PCR method was set up to detect delta infection from serum samples. Moreover, the target amplified sequ...

BACKGROUND There is no standard management of reactivation of hepatitis B virus (HBV) infection in HBV-resolved patients without hepatitis B surface antigen (HBsAg), but with antibodies against hepatitis B core antigen and/or antibodies against HBsAg (anti-HBs). METHODS We conducted a prospective observational study to evaluate the occurrence of HBV reactivation by serial monthly monitoring o...
