Objective: To explore the regularity of serological conversion of blood group in BM empty phase of ABO-incompatible allogeneic stem cell transplantation so as to provide the basis for selecting the blood components in blood transfusion.
Methods: Before hematpoietic stem cell transplantation (HSCT), the ABO and RhD blood groups of recipients and donors were identified by salt medium tube method and microcolumn gel method; after transplantation the changes of antigen intensity and antibody titer of ABO blood group in patients were periodically detected.
Results: After blood group shift of 33 patients received ABO-incompatible allo-HSCT, the consistent rate of positive and regative types in major ABO incompatible group was 100%; the consistent rate of positive and negative types in minor ABO-incompatible group was 33%, no-consistent rate was 66.7%; the consistent rate of positive and negative types in bidirextional ABO incompatible group was 20%, the no-consistent rate was 80%.
Conclusion: After ABO-incompatible allo-HSCT, blood group antgen of patients shifts to the blood group of donors, there is a significant difference in the serological indicators between the minor and bidireetional ABO-incompatible patients and normal people.
