Summary

Hepatitis C virus (HCV) antibody prevalence in Venezuela is 1.2%, double that of industrialized nations. This study highlights HCV as a significant public health concern, often co-occurring with Hepatitis B virus (HBV) infection.

Area of Science:

  • Hepatology
  • Virology
  • Public Health

Background:

  • Hepatitis C virus (HCV) infection is a global health issue.
  • Accurate prevalence data is crucial for public health interventions.
  • Previous HCV prevalence data in Venezuela was limited.

Purpose of the Study:

  • To determine the prevalence of anti-HCV antibodies in Venezuelan blood donors.
  • To assess the co-occurrence of HCV with other hepatitis viruses (HAV, HBV) and autoimmune liver disease.
  • To evaluate a newly developed enzyme-linked immunoassay for anti-HCV detection.

Main Methods:

  • Enzyme-linked immunoassay (ELISA) was used to detect anti-HCV antibodies.
  • Serum samples from 500 blood donors were analyzed.
  • Additional patient groups with Non-A Non-B hepatitis, HAV/HBV negative screening, and autoimmune chronic hepatitis were included.

Main Results:

  • A true-positive prevalence of 1.2% (6/500) for anti-HCV antibodies was found, which is double the rate in industrialized countries.
  • One positive case (16.6%) showed co-reactivity for Hepatitis B virus (HBV) anticore antibody.
  • Anti-HCV antibodies were detected in 25% of Non-A Non-B hepatitis patients and 12.5% of HAV/HBV-negative individuals.

Conclusions:

  • Hepatitis C virus represents a significant public health problem in Venezuela.
  • HCV infection frequently coexists with HBV infection.
  • The findings underscore the need for enhanced HCV screening and management strategies in Venezuela.
