Blood group changes in acute myeloid leukemia and their relationship with therapeutic effect
Journal Title: Chinese Journal of Blood Transfusion - Year 2024, Vol 37, Issue 6
Abstract
Objective To explore the blood group changes of two acute myeloid leukemia patients with suspected O type, and their relationship with the therapeutic effect. Methods Serological analysis of ABO blood group of patients was carried out by microcolumn gel method, tube method and absorption-elution test, ABO blood group genotyping was performed by microfluidic chip method. Exons E2 to E7 of ABO gene were amplified by PCR and sequenced by Sanger method. Results The forward typing of two cases were both O type, but the reverse typing were both A type. The absorption-elution test results all showed detection of antigen A. ABO gene phenotype of the two cases were both A, with genotyping results as A102/A102 and A102/O01, respectively. Sequencing results showed that SNP sites of ABO blood group were 467T/T, 261G/delG and 467C/T, respectively.In one case, the intensity of anti-A agglutination reaction changed significantly from weak to strong with the progress of treatment. Conclusion For clinical samples of acute myeloid leukemia patients with ABO forward and reverse typing discrepancy and suspected O type, the result of reverse typing should be valued, and absorption-elution test should be performed to further confirm the ABO blood type combining the genetic test results, so as to develop appropriate blood transfusion strategies for patients.
