Summary

A case of transfusion-transmitted malaria occurred in a patient with sickle cell disease despite the donor meeting all guidelines. This incident prompted proposed changes to UK donor selection to prevent future malaria transmission via blood transfusions.

Area of Science:

  • Infectious Diseases
  • Hematology
  • Public Health

Background:

  • Transfusion-transmitted malaria poses a risk, particularly in immunocompromised individuals.
  • A 50-year-old male with sickle cell disease received a blood transfusion that transmitted malaria.
  • The donor, a Ghanaian migrant residing in the UK for years, met existing donor guidelines.

Purpose of the Study:

  • To report a case of transfusion-transmitted malaria.
  • To highlight the inadequacy of current donor selection guidelines in preventing malaria transmission.
  • To propose revisions to donor selection criteria in the UK.

Main Methods:

  • Case report analysis.
  • Review of donor screening protocols.
  • Investigation of donor's parasitaemia and antibody levels.

Main Results:

  • The donor was found to be parasitaemic with high malarial antibody titres.
  • Despite meeting all current guidelines, the donation resulted in malaria transmission.
  • The case identified a critical gap in donor selection criteria.

Conclusions:

  • Current UK donor selection guidelines are insufficient to prevent transfusion-transmitted malaria.
  • Proposed changes to donor screening are necessary to mitigate this risk.
  • Enhanced vigilance and revised protocols are crucial for blood transfusion safety.
