Mutations in the Basal Core Promoter and Precore/Core Regions of Hepatitis B Virus in Patients Co-Infected With Human Immunodeficiency Virus
ABSTRACT Background and objectives: Globally, about one third of the population has been infected with Hepatitis B virus (HBV) and more than 400 million people have become chronically infected. Nearly, 20-25% of all carriers develop serious liver diseases such as cirrhosis, chronic hepatitis and hepatocellular carcinoma (HCC). According to t...
متن کاملmutations of basal core promoter and precore regions in hepatitis b virus genotypes b and c
conclusions the mutation ratio difference between genotypes b and c in children was higher than that of adults and several combined mutations were exclusively detected in children with chronic hbv genotype c infection associated with higher viral load. objectives the aim of this study was to assess the mutation profiles of bcp and precore regions in different hbv genotypes in chronically infect...
متن کاملMutations of Basal Core Promoter and Precore Regions in Hepatitis B Virus Genotypes B and C
BACKGROUND Mutations in basal core promoter (BCP) and precore regions of hepatitis B virus (HBV) are associated with course and treatment outcomes of chronic HBV infection. While BCP and precore mutation analysis have been carried out in adult patients between different genotypes, this analysis has rarely been performed for chronically infected children. OBJECTIVES The aim of this study was t...
متن کاملHepatitis B virus core promoter and precore mutations and their relatedness to genotypes and disease pathogenesis
Despite the successful vaccination programme worldwide, Hepatitis B virus infection remains a global problem. Infection rate in developing countries is higher in comparison to the developed countries. Core promoter region (nts.1591-1822) plays a very important role in HBV replication, morphogenesis and pathogenesis, whereas the precore region (nts.1814 to 1901) contains the start site for synth...
متن کاملMutations in pre-core and basal-core promoter regions of hepatitis B virus in chronic HBV patients from Golestan, Iran
Objective(s): It has been reported that the mutation of the pre-core (PC) and basal-core promoter (BCP) may play an important role in the development of HBV-related hepatocellular carcinoma (HCC). In this study the PC and BCP mutations were investigated in chronic HBV patients. Materials and Methods:In this study, 120 chronic HBV patients from Golestan, Northeast of Iran who were not vaccinated...
