Insights

Hepatitis B and C virus (HBV and HCV) coinfection shows diverse virological patterns. HCV core gene variability does not influence HBV activity in coinfected patients.

Area of Science:

  • Hepatology
  • Virology
  • Infectious Diseases

Background:

  • Hepatitis B virus (HBV) and Hepatitis C virus (HCV) coinfection profiles are not fully understood.
  • Occult HBV infection can occur in HBsAg-negative patients with chronic HCV.
  • HCV core protein may inhibit HBV replication in vitro.

Purpose of the Study:

  • To investigate HBV and HCV virological profiles in coinfection.
  • To assess the relationship between HCV core gene variability and HBV activity.

Main Methods:

  • Examined 82 anti-HCV positive patients (HBsAg positive, HBsAg negative with occult HBV, HBV negative).
  • Evaluated HBV and HCV viremia levels.
  • Sequenced the HCV core gene (amino acid sequence 99-116 and entire gene).

Main Results:

  • Diverse virological patterns observed in coinfection.
  • HCV viremia levels were similar across groups.
  • HCV core gene showed high preservation; no link to HBV activity found.

Conclusions:

  • Coinfection with HCV and HBV presents a wide range of virological patterns.
  • HCV core gene variability is not associated with HBV activity in vivo.

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 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...

Viruses with RNA Genomes

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...
