Viral hepatitis remains a serious risk after blood transfusions, though incidence has decreased. Mexico

Area of Science:

  • Transfusion Medicine
  • Hepatology
  • Infectious Diseases

Background:

  • Viral hepatitis is a significant complication of blood transfusions, posing a high mortality risk.
  • Despite reductions, viral hepatitis transmission via transfusion persists, with an estimated Hepatitis C Virus (HCV) risk of 1 in 103,000 units in Mexico.
  • Transmission routes include infected blood products like whole blood (IgG), anti-D immunoglobulin, and factor VIII.

Purpose of the Study:

  • To assess the impact of new regulations on blood transfusion safety in Mexico.
  • To evaluate the current prevalence of Hepatitis C Virus (HCV) infection in blood donors.
  • To highlight the testing strategies employed to ensure blood product safety.

Main Methods:

  • Analysis of national blood transfusion regulations and their effect on donor infection rates.

  • Estimation of Hepatitis C Virus (HCV) prevalence in the Mexican donor population.
  • Review of diagnostic tests, including Polymerase Chain Reaction (PCR) and core HCV antigen detection for Acquired Hepatitis C (AcHC).

    • Main Results:

    • New blood transfusion regulations in Mexico led to a 57% reduction in infection prevalence among donors.
    • The national prevalence of HCV in 2001 was estimated at 0.01%.
    • Advanced diagnostic tests are being implemented to enhance blood product safety.

    Conclusions:

    • Official regulations have significantly improved blood transfusion safety in Mexico.
    • Ongoing implementation of sensitive testing methods like PCR is crucial for continued risk reduction.
    • Vigilance and advanced screening are essential to minimize viral hepatitis transmission through blood transfusions.
