Abstract:
Background: Patients who received multiple transfusions of blood and blood products may produce antibodies against antigens of erythrocytes, leukocytes, platelets etc, resulting in many clinical implications. Objectives: To detect frequencies of antineutrophil antibodies in multitransfused patients at National Institute of Hematology and Blood Transfusion (NIHBT). Subjects and methods: The study was conducted on 30 multitransfused patients. Among them there were 12 with thrombocytopenia and 18 with aplastic anemia. Results: 6 cases had anti - neutrophil antibodies, of which 5 had more than 5 times of transfusion, 4 with aplastic anemia and 2 with thrombocytopenia. The sera were further tested with neutrophil panel, revealing 4 samples with anti - NA 1 (13.3%) and 1 sample with anti - NA2 (3.3%). The frequency of anti - neutrophil antibodies in multitransfused patients at IHBT in the study is 20%. Conclusion: Frequency of anti-NA1 was higher than anti-NA2 in multitransfused patients at NIHBT and directly proportional by frequency of NA1 and NA2 antigens in this group. The technical process to identify and classify antineutrophil antibodies in this study can be applied for patients who received multiple transfusions of blood and blood products in Viet Nam
