Analysis of red blood cell alloimmunization among inpatients: 104 588 cases
Journal Title: Chinese Journal of Blood Transfusion - Year 2023, Vol 36, Issue 3
Abstract
Objective To analyze the yield, specificity and detection time of red blood cell(RBC)alloimmunization in 104 588 inpatients. Methods The clinical information of patients who underwent at least one antibody screening in our hospital from November 2017 to December 2019 was retrospectively analyzed. The demographic characteristics, transfusion history, pregnancy history and antibody screening results of patients were collected. The RBC alloantibody yield, specificity and detection time were analyzed, and differences of transfusion units and frequency between patients with and without alloimmunization were compared. Results Eight hundred cases of alloantibodies with clinical significance were detected in blood samples of 723 patients, with a positive rate of 0.7% (723/104 588). The incidence rate of alloimmunization in females was higher than that in males (0.9% vs 0.5%, P<0.05). Rh alloantibodies accounted for 76.4%(611/800), of which 61.4%(375/611)were anti-E. Transfusion units and frequency of patients with alloimmunity were higher than those without(median: 6.0 vs 4.0, P<0.05; 4.0 vs 2.0, P<0.05, respectively). And 67.5% of RBC alloantibodies were detected within 6 months, with the median (IQR) detection time of 97.0 (22.5-247.0) days. Conclusion Routine antibody screening should be performed before transfusion in order to reduce the occurrence of adverse reactions, and Rh typing transfusion with compatible crossmatch should be performed if necessary.
