OBJECTIVE To see effect of Lamivudine on sero conversion of HBeAg positive cases co infected with Delta hepatitis. METHODS Hepatitis B positive patients with deranged liver functions for 6 months were tested for HBeAg, HBV DNA and anti-Delta virus (HDV), using ELISA. Patients were divided into 2 groups, group 1: HBeAg, HBV DNA positive (wild type) but delta negative and group 2: HBeAg, HBV DN...

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...

UNLABELLED Non-Hodgkin lymphoma is a cancer of the lymphatic tissue located in various parts of the body: lymph nodes, spleen, thymus, adenoids, tonsils, and bone marrow. The disease occurs mainly in adults, with a higher incidence within the age range of 45 to 60 years. We present a clinical case of non-Hodgkin lymphoma diagnosed in a patient with chronic viral hepatitis B and D. The particula...

Hepatitis delta virus (HDV) is a defective RNA virus with similarities to unusual subviral pathogens of higher plants. It requires hepatitis B virus (HBV) for its replication/transmission, and HBV-infected humans are the only established host. HDV causes both severe acute hepatitis and rapidly progressive chronic disease in some individuals. The HDV life cycle involves remarkable features, such...

Members of the family Hepadnaviridae fall into two subgroups: mammalian and avian. The detection of endogenous avian hepadnavirus DNA integrated into the genomes of zebra finches has revealed a deep evolutionary origin of hepadnaviruses that was not previously recognized, dating back at least 40 million and possibly >80 million years ago. The nonprimate mammalian members of the Hepadnaviridae i...

Clathrin-mediated endocytosis is a common pathway for viral entry, but little is known about the direct association of viral protein with clathrin in the cytoplasm. In this study, a putative clathrin box known to be conserved in clathrin adaptors was identified at the C terminus of the large hepatitis delta antigen (HDAg-L). Similar to clathrin adaptors, HDAg-L directly interacted with the N te...

AIM & SCOPE It has been widely established that several virus infections are strictly correlated to the cancerogenesis and may induce, through their reactivation, severe damages during chemotherapy treatments. For example, the direct role that Hepatitis B virus (HBV) plays in the development of liver cancer is well known. Nevertheless, in other cases, as Hepatitis C virus (HCV) or Hepatitis Del...
