Nonimmune transfusion reactions: when type-and-cross match aren't enough
1Pharmacy Corporation of America, Greensboro, North Carolina, USA.
Summary
Transfusion reactions can occur due to immune responses from blood incompatibilities or nonimmune factors related to blood handling. Understanding these nonimmune transfusion reactions is crucial for patient safety.
Area of Science:
- Transfusion Medicine
- Hematology
- Immunology
Background:
- Blood component administration carries inherent risks of adverse reactions.
- Reactions can be immune-mediated (due to antigen mismatch) or nonimmune.
- Nonimmune reactions may arise from collection, preparation, or administration processes.
Purpose of the Study:
- To discuss nonimmune transfusion reactions.
- To highlight factors influencing patient tolerance to transfusions.
- To detail nine specific nonimmune transfusion reactions.
Main Methods:
- Review of literature on transfusion reactions.
- Categorization of reactions into immune and nonimmune.
- Discussion of predisposing patient factors.
- Analysis of nine case examples of nonimmune reactions.
Main Results:
- Immune reactions stem from blood antigen incompatibilities.
- Nonimmune reactions can occur even with perfect antigenic matches.
- Factors like patient's health status and blood product handling influence reactions.
- Nine distinct nonimmune transfusion reactions were identified and discussed.
Conclusions:
- Nonimmune transfusion reactions are a significant concern in transfusion medicine.
- Patient-specific factors and procedural elements contribute to nonimmune reactions.
- Awareness and management of these reactions are vital for safe transfusion practices.
