Pure red cell aplasia following major ABO-incompatible allogeneic hematopoietic stem cell transplantation

OBJECTIVES: To study clinical characteristics and outcome of pure red cell aplasia (PRCA) following major ABO-incompatible allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODS: Variables including sex, age, stem cell source, granulocyte engraftment time, blood transfusion and isoagglutinin type against donor RBC were analyzed to identify risk factors for the development of PRCA.

RESULTS: Twelve of 100 patients received major ABO-incompatible allo-HSCT developed PRCA, with out any effect on incidence of aGVHD and CMV infection. ABO blood groups of recipient/donor pairs of these twelve PRCA patients were O/A in nine, B/A in one and O/B in two. Patients with anti-A isoagglutinins against donor RBC developed PRCA more frequently than those with anti-B (10/49 vs 2/49). Median duration to the recovery of erythropoiesis tended to be longer in patients with PRCA (PRCA vs non-PRCA, 203.5 vs. 76 days, P < 0.05 ). Median durations to the disappearance of incompatible isoagglutinins tended to be longer in patients with PRCA (PRCA vs. non-PRCA, 150.5 vs. 60 days,P <0.05) and in those with anti-A isoagglutinins (anti-A vs anti-B, 90 vs 55 days, P < 0.05).

CONCLUSION: ABO blood group of O/A in recipient/donor pair was the only high risk factor for PRCA after major ABO-incompatible allo-HSCT.
