Blood transfusion compatibility in patients with delayed serologic transfusion reaction: a retrospective analysis of 6 cases
Journal Title: Chinese Journal of Blood Transfusion - Year 2023, Vol 36, Issue 10
Abstract
Objective To retrospectively analyze the characteristics of blood transfusion compatibility detection in patients with delayed serologic transfusion reaction ( DSTR), in order to provide reference for safe and effective blood transfusion in clinical practice. Methods From April 2020 to July 2021, 6 samples of patients who applied for blood type identification, unexpected antibody screening and transfusion from the Third People′s Hospital of Chengdu or People′s Hospital of Sichuan Province were collected. Microcolumn method was used for identification of ABO and RhD blood type of patients; unexpected antibody screening, blood cross-match, antibody identification and direct anti-human globulin tests were also conducted. The sensitizing antibodies on the surface of red blood cells were identified by acid release solution, and the antigen-antibody reaction was enhanced by polyethylene glycol. The patients′ own red blood cells and input red blood cells were separated by capillary high-speed centrifugation, and the surface antigens of red blood cells were detected by serological method. Meanwhile,the characteristics of patients before and after transfusing antigen-positive red blood cells were summarized. Results Anti-E was detected in the plasma of patients 1 and 2, and anti-c,-E were detected in the red blood cell release solution, while anti-C, anti-E, anti-JKa and anti-Fyb were detected in the plasma and red blood cell release solution of patients 3, 4, 5 and 6, respectively. After capillary high-speed centrifugation, antigen-positive red blood cells were detected in the distal end of the blood samples of 6 patients. Conclusion For patients with multiple blood transfusions and a recent history of blood transfusion, when newly emerging erythrocyte antibodies with clinically significance, direct anti-human globulin test(+) or erythrocyte antibody screening(+) are detected, and the patient has no clinical symptoms of hemolysis, it should be suspected as DSTR occurrence, and the transfusion reaction investigation procedure should be initiated in time.
