Summary
This study investigated blood transfusions in sensitized patients, finding high rates of alloimmunization. Individualized immunohematological matching significantly reduced adverse reactions, improving transfusion effectiveness.
Area of Science:
- Immunohematology
- Transfusion Medicine
- Immunogenetics
Background:
- Investigated immunohematological profiles of 162 blood transfusion-dependent sensitized patients.
- Identified high prevalence of alloimmunization to leukocyte (HLA) and erythrocyte antigens.
Observation:
- 74.0% of patients showed immunization to Human Leukocyte Antigen (HLA) antigens.
- 25.4% of patients were immunized to erythrocyte antigens, with one case of rare Rh-Hr system immunization.
- Extensive red cell and leukocyte antigen typing was performed for donors, recipients, and relatives.
Findings:
- Individualized blood matching based on ABO, Rh-Hr, MNSs, P, Duffy, Kidd, Kell-Chellano, and HLA systems was crucial.
- Compatibility testing included basic red cell antigens and wide-spectrum HLA antigens.
- Transfusions conducted after immunological matching resulted in no adverse reactions.
Implications:
- Immunological matching is essential for safe and effective blood transfusions in sensitized patients.
- Reduces the risk of transfusion reactions and improves patient outcomes.
- Highlights the importance of comprehensive antigen typing in transfusion medicine.
