Study Summary

This is a pilot study to evaluate the feasibility and safety of providing RH genotype matched D+ Red Blood Cells (RBCs) to chronically transfused patients with sickle cell disease (SCD) who type D+ but have formed anti-D and are currently transfused with D- RBC (Red Blood Cell) units.

Primary Outcome

To determine safety of providing RH genotype match red cells to patients with a history of anti-D, we observed if anti-D reappearance occurred or evidence of hemolysis of transfused red cells.

Interventions

  • BIOLOGICAL D+ RH genotype matched red cell units for transfusion
