Cytomegalovirus (CMV) infection poses risks to immunocompromised individuals. Screening donors for CMV antibodies and selecting younger donors can improve blood safety for vulnerable patients.

Area of Science:

  • Virology
  • Immunology
  • Transfusion Medicine

Context:

  • Cytomegalovirus (CMV) infection is a significant threat to immunocompromised individuals, including bone marrow transplant recipients and preterm infants.
  • Effective treatments for CMV are lacking, making prevention crucial.
  • Blood transfusions represent a potential route of CMV transmission, necessitating screening of blood donors.

Purpose:

  • To determine the prevalence of Cytomegalovirus (CMV) antibodies among blood donors in Taiwan.
  • To investigate the correlation between donor age and CMV seropositivity.
  • To inform strategies for selecting CMV-negative blood donors.

Summary:

  • A study screened 2,015 donors in Taiwan for CMV antibodies using the passive latex agglutination (PLA) test.

  • The overall CMV antibody positive rate was 91.7%, higher than in Western countries but comparable to other Asian and African regions.
  • CMV seropositivity increased significantly with donor age, with seronegative rates decreasing from 10.7% in 18-20 year olds to 0% in 51-60 year olds.

    • Impact:

    • The findings highlight the high CMV prevalence in Taiwan, emphasizing the need for rigorous donor screening.
    • The strong age-related correlation suggests prioritizing younger donors for CMV-negative blood component preparation.
    • Implementing age-based donor selection can enhance the safety of blood transfusions for immunocompromised patients.
