Active hepatitis C virus (HCV) infection can persist without causing liver disease. This study found persistent HCV RNA in symptom-free individuals, with normal liver tests and biopsies, indicating no liver damage.

Area of Science:

  • Hepatology
  • Virology
  • Immunology

Background:

  • Viral persistence does not always equate to disease.
  • Hepatitis C virus (HCV) infection can be asymptomatic.
  • Understanding HCV persistence is crucial for disease management.

Purpose of the Study:

  • To investigate if active hepatitis C virus (HCV) infection can persist without causing liver disease.
  • To determine the relationship between persistent HCV viraemia and liver damage in asymptomatic individuals.

Main Methods:

  • Selection of four individuals with anti-HCV antibodies and normal aminotransferase levels.
  • Monthly serological testing and HCV RNA detection over 3 years.
  • Liver biopsy performed to assess liver health.

Main Results:

  • All participants had persistent HCV antibodies and circulating HCV RNA throughout the 3-year follow-up.
  • Aminotransferase levels remained normal in all subjects.
  • Liver biopsies showed no signs of liver damage.

Conclusions:

  • Persistent hepatitis C viraemia can occur without evidence of liver disease.
  • Asymptomatic HCV infection may not invariably lead to liver damage.
  • Further research is needed to understand the mechanisms behind non-progressive HCV infection.
