Abstract:
This study was purposed to investigate the effect of ABO-incompatible allogeneic hematopoietic stem cell transplantation (allo-HSCT) on erythroid lineage hematopoiesis. The changes of ABO group, IgM and IgG antibody in 16 patients received ABO-incompatible allo-HSCT were detected. The results showed that ABO-incompatible allo-HSCT were successfully engrafted in 16 patients, and there was no difference in reconstitution of platelets and neutrophils between ABO-incompatible and ABO-compatible transplantation (p > 0.05). The time of erythroid lineage reconstitution was prolonged (p < 0.05), the disappearance time of isoagglutinins against donor-type RBC in major and bidirectional ABO-incompatible recipients was correlated with the time of erythroid lineage reconstitution. It is concluded that ABO-incompatible allo-HSCT may lead to prolong recovery of erythroid lineage hematopoiesis. Before transplantation, the removal of anti-donor isoagglutinins by plasmapheresis or transfusion of donor's erythrocytes for neutralizing the isoagglutinins against donor's erythrocytes in the recipients may facilitate RBC engraftment and reduce erythrocyte transfusion.

Factors Affecting Erythropoiesis
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
