|Alloimmunization Sickle Cell Disease|
The main objectives of this study are to study the role of the innate and adaptive immune response in allo-antibody formation and furthermore to identify the genetic and time dependent clinical risk factors on alloimmunization in SCD patients.
Subjects without allo-antibodies, receiving a red blood cell transfusion, will be included in this study. At 5 time points blood will be drawn from these subjects. (T0: Before transfusion, T1: 1 day after transfusion, T2: 1 week after transfusion, T3: 4 weeks after transfusion, T4: 6 months after transfusion).
At each time point specific markers of the immune system will be measured.

- The innate and adaptive immune response of patients with sickle cell disease that form allo-antibodies following erythrocyte transfusion, compared to patients that do not form alloantibodies following erythrocyte transfusion [ Time Frame: 6 months ]Multiple activating and regulatory markers of the innate and adaptive immune system will be measured at the indicated time points and compared between cases and controls
