Insights

Hepatitis B virus (HBV) mutations in the C and P genes are common in chronic hepatitis B patients, often leading to antiviral treatment failure. Early detection of these mutations is crucial for effective patient management.

Area of Science:

  • Hepatology
  • Virology
  • Genetics

Context:

  • Chronic hepatitis B (CHB) is a significant global health concern.
  • Hepatitis B virus (HBV) infection can lead to serious liver disease.
  • Antiviral treatment failure in CHB is a growing clinical challenge.

Purpose:

  • To investigate the prevalence of HBV C and P gene mutations in CHB patients.
  • To determine the association between specific mutations and antiviral treatment outcomes.
  • To identify common HBV genotypes in the studied population.

Summary:

  • Genotyping of HBV C and P genes was performed on 75% of CHB patients over five years.
  • Mutations in precore/basal core promoter regions were found in 75% of patients.
  • Antiviral resistance mutations were present in 37% of patients, with genotypes A and D being most frequent.

Impact:

  • Findings highlight the high prevalence of HBV mutations contributing to treatment failure.
  • Early detection of resistance mutations is recommended to optimize CHB management.
  • Understanding genotype distribution aids in predicting treatment response and disease progression.

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material for adaptive...

Mechanisms of Retrovirus-induced Cancers

Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Mutations in Microorganisms

Mutations are heritable changes in an organism’s genome involving alterations in the base sequence of DNA or RNA. These changes can influence cellular processes and phenotypic traits, potentially transforming the unaltered wild type into a mutant form. Such changes, termed forward mutations, are pivotal in shaping the genetic diversity of organisms.RNA viruses exhibit the highest mutation rates due to the absence of robust proofreading mechanisms during genome replication. In contrast,...
