Abstract
additional measures to ensure the immunological safety of allogeneic transfusions.
Aim. To study the features of ensuring the immunological safety of allogeneic transfusions in patients with hematological malignancies.
Materials and methods. For the period 2020–2024, the results of immunohematological studies of 10,276 blood samples from patients requiring individual selection of erythrocyte-containing components of donor blood were analyzed. Of these, 1129 (10.9 %) were oncohematological patients; 28 (0.3 %) were patients with established refractoriness to platelet concentrate transfusions requiring individual selection of this concentrate, of which oncohematological diseases were observed in 26 cases. All necessary studies were carried out at the immunological reference center of the Novosibirsk Clinical Blood Center.
Results. The proportion of oncohematological patients who required individual selection of erythrocyte-containing blood components was 10.8 % for patients with newly detected anti-erythrocyte antibodies and 11.1 % for those with previously established antibodies. In patients with hematological malignancies, polyspecificity of antibodies is significantly more common (83.1 % of all cases of polyspecificity) and difficult to identify (61.7 % of samples with unknown specificity). The selection of a single red blood cells dose requires significantly (2.2 times) more studies and compatibility testing, extended typing, and significant reserves of erythrocyte-containing blood components for clinical use. The effectiveness of individual selection of erythrocyte-containing blood components in an immunological reference center for oncohematological patients was 98.2 %.
Conclusion. Centralization of immunological testing at the Novosibirsk Clinical Blood Center has ensured the effectiveness of individual selection for patients with alloimmunization and antibody production to clinically significant antigens of erythrocyte-containing blood components in 99.7 % of cases, and individual selection of platelet concentrate for patients with transfusion refractoriness in 92.8 % of cases, including for patients with anti-HLA antibodies in 71.4 % of cases.
