- Changes in Biochemical Effects - Band 3 Phosphorylation [ Time Frame: change from baseline Band 3 Phosphorylation at 7 months ]Percent change in Band 3 Phosphorylation tested in red blood cells
- Changes in Biochemical Effects - Microparticle Release [ Time Frame: change from baseline micro particle release at 7 months ]Percent change in Microparticle Release tested in red blood cells
- Change in Functional RBC analysis [ Time Frame: change from baseline functional RBC at 7 months ]Percent Irreversibly Sickled Cells by ektacytometry and Percent altered susceptibility to sickling by OxygenScan
- Vaso-occlusive Crisis (VOC) [ Time Frame: monthly over 7 months ]Defined as an acute episode of pain lasting greater than 24 hours, with no medically determined cause other than a vaso-occlusive event that resulted in treatment with oral or parenteral opiate agents and/or parenteral nonsteroidal anti-inflammatory agents. Measured by pain scale (1-10) or Wong-Baker Faces scale based on age:
- Acute Chest Syndrome (ACS) [ Time Frame: monthly over 7 months ]Defined as respiratory distress (hypoxia, shortness of breath, chest pain, tachypnea) with evidence of an infiltrate on chest x-ray Measured with clinical evaluation.
- Opioid Use [ Time Frame: monthly over 7 months ]Defined as both oral and parenteral opioid use Oral use will be documented in pain diary by patient/guardian and reviewed at each visit.
- Hospitalizations [ Time Frame: monthly over 7 months ]Defined as an emergency room or clinic visit resulting in an inpatient admission or observation for a sickle cell-related event (e.g. vaso-occlusive pain, acute chest syndrome, etc).
- Assessment toxicities of imatinib in patients with sickle cell anemia (SCA) [ Time Frame: monthly over 7 months ]Clinical evaluation
