Transfusion-acquired Plasmodium malariae infection in two premature infants
Insights
Transfusion-transmitted infections pose risks to infants, especially premature ones receiving frequent blood transfusions. Malaria should be considered in sick premature infants unresponsive to antibiotics, as screening is impractical in non-endemic areas.
Area of Science:
- Neonatal Medicine
- Infectious Diseases
- Transfusion Medicine
Background:
- Infants, particularly premature infants, have immature immune systems, increasing their susceptibility to infections.
- Sick premature infants often require frequent blood transfusions, elevating their risk of transfusion-transmitted diseases.
- Immunocompromised infants are highly vulnerable to infections acquired through blood transfusions.
Observation:
- Transfusion-acquired infections present a significant risk to infants.
- Premature infants are at a substantially higher risk for transfusion-related infections due to frequent transfusions and immunological incompetence.
- Malaria screening in blood donations is not routinely performed in non-endemic regions.
Findings:
- Sick premature infants receiving frequent transfusions are at increased risk of transfusion-acquired infections.
- Physicians should consider transfusion-acquired malaria in premature infants who do not respond to standard antibacterial treatments.
- The risk of transfusion-acquired malaria is a concern, especially when routine screening is not feasible.
Implications:
- Highlighting the need for vigilance regarding transfusion-transmitted malaria in vulnerable infant populations.
- Suggests considering malaria in the differential diagnosis of febrile illnesses in premature infants, particularly those who have received transfusions.
- Underscores the importance of considering non-bacterial causes of infection in infants who fail to improve with antibiotic therapy.
Abstract:
Several diseases can be transmitted to infants via transfusion. The risk of acquiring an infection via transfusion is greatly increased in sick premature infants because they receive frequent transfusions. The full-term infant is not fully competent immunologically, and the premature infant is even less able to deal with infection. Ideally, the transfusion of infected blood, especially into immunoincompetent recipients, should not occur. However, because screening for malaria in nonendemic regions is not practical, physicians caring for sick premature babies should consider transfusion-acquired malaria as a possible cause of illness, especially when there is no response to antibacterial therapy.
