Summary
To determine the feasibility of matching donor red cells by RH genotype for a cohort of chronically transfused patients with SCD.
Description
This is a pilot feasibility study in patients with Sickle Cell Disease requiring chronic red cell transfusions. RH genotyped donor units will be obtained from the New York Blood Center. Patients will be matched with donor units whose RH genotypes predict no foreign Rh protein exposure to the patient. This will provide red cell matching at a level above the current standard of care (serologic C, E, and K matching). Patients will receive RH matched red cells for the duration of their chronic transfusion therapy or up to five years, whichever is shorter. It will then be determined whether sufficient RH matched donor units can be identified for the patient's RH genotype. Although not powered to determine effectiveness, all patients's Rh alloantibody formation will be monitored.
For subjects with a history of stroke/recurrent transient ischemic attack or other indication who require tight control of Hb S, and RH genotyped blood is not available, standard of care serologic matched blood would be administered rather than delaying transfusion and risking higher Hb S level.
For all subjects, standard of care serologic matched blood would be administered rather than delaying transfusion beyond 7 days.
