Detection and analysis of two drug-induced antibodies in suspicious blood samples from pre-transfusion compatibility tests
Journal Title: Chinese Journal of Blood Transfusion - Year 2022, Vol 35, Issue 8
Abstract
Objective To detect the piperacillin and amoxicillin antibodies in suspicious blood samples from pre-transfusion compatibility tests in Wuxi and analyze the general characteristics of them, so as to eliminate the interference of drug-induced antibodies with compatibility tests and provide reference for safe and effective blood transfusion, Methods Drug-sensitized RBCs and low-ion anti-globulin microcolumn gels were used to detect piperacillin and amoxicillin antibodies in 128 plasma samples which were initially undetermined in pre-transfusion compatibility tests. Data were analyzed by Chi-square test or fisher′s exact test. P<0.05 was statistically significant. Results Among these 128 undetermined samples, including 31 cases of type A, 48 type B, 14 type AB and 35 type O, the overall positive rate of piperacillin and amoxicillin antibodies was 28.9%(37/128), in which the positive rates of piperacillin and amoxicillin antibodies were 20.3%(26/128) and 8.6%(11/128), respectively. The difference between these two drug-induced antibodies was significant(P<0.05). Further analysis showed that the piperacillin antibodies in patients over 50 years old was 25.3%(24/95), while under 50 years old was 6.1%(2/33)(P<0.05). In contrast, the amoxicillin antibodies in patients over 50 years old was 5.3%(5/95), while under 50 years old was 18.2%(6/33), with statistically significant differences between each other(P<0.05). Conclusions In patients with suspicious antibodies in pre-transfusion detection, except for the allotype antibodies, drug-induced antibodies should be more considered in combination with medication history to better ensure the safety and effectiveness of blood transfusion.
