Effectiveness of red blood cell exchange, partial manual exchange, and simple transfusion concurrently with iron chelation therapy in reducing iron overload in chronically transfused sickle cell anemia patients.
CONCLUSION: We recommend RCE plus chelation as an effective method for reducing iron overload, while maintaining HbS at 30% to 35%.

Reduction in Overt and Silent Stroke Recurrence Rate Following Cerebral Revascularization Surgery in Children with Sickle Cell Disease and Severe Cerebral Vasculopathy
ConclusionsThe rate of overt and silent infarct recurrence was significantly lower following indirect cerebral revascularization. A prospective study of cerebral revascularization in children with SCD is needed.

Management of Patients with Sickle Cell Disease Using Transfusion Therapy
Red blood cell (RBC) transfusion therapy is a key component of comprehensive management of patients with sickle cell disease (SCD) and has increased over time as a means of primary and secondary stroke prevention. RBC transfusions also prove to be lifesaving for many acute sickle cell–related complications. Although episodic and chronic transfusion therapy has significantly improved the morbidity and mortality of patients with SCD, transfusions are not without adverse effects. This review addresses RBC transfusion methods, evidence-based and/or expert panel–based consensus on indications for chronic and episodic transf...

Pediatric Sickle Cell Disease - Past Successes and Future Challenges.
Abstract
Once a fatal disease of childhood, more than 95% of patients born today with sickle cell disease (SCD) in developed countries are expected to survive into adulthood, largely because of improvements in supportive and preventive care (newborn screening, penicillin prophylaxis, transcranial Doppler (TCD) screening). Hydroxyurea (HU) therapy, the only oral medication currently available to prevent SCD complications, has become more widespread over the past 20 years. The NHLBI recommends that HU be offered to all patients with HbSS beginning at nine months of age, and the recently published Abnormal TCD with T...

Red cell exchange transfusions lower cerebral blood flow and oxygen extraction fraction in pediatric sickle cell anemia
Blood transfusions are the mainstay of stroke prevention in pediatric sickle cell anemia (SCA), but the physiology conferring this benefit is unclear. Cerebral blood flow (CBF) and oxygen extraction fraction (OEF) are elevated in SCA, likely compensating for reduced arterial oxygen content (CaO2). We hypothesized that exchange transfusions would decrease CBF and OEF by increasing CaO2, thereby relieving cerebral oxygen metabolic stress. Twenty-one children with SCA receiving chronic transfusion therapy (CTT) underwent magnetic resonance imaging before and after exchange transfusions. Arterial spin labeling and asymmetric s...

Simple chronic transfusion therapy, a crucial therapeutic option for sickle cell disease, improves but does not normalize blood rheology: What should be our goals for transfusion therapy?
Abstract
Sickle cell anemia is characterized by a mutation resulting in the formation of an abnormal beta-hemoglobin called hemoglobin S. Hemoglobin S polymerizes upon deoxygenation, causing impaired red blood cell deformability and increased blood viscosity at equivalent hematocrits. Thus, sickle cell disease is a hemorheologic disease that results in various pathologic processes involving multiple organ systems including the lungs, heart, kidneys and brain. Red blood cell mechanics and the perturbations on blood flow-endothelial interaction underlie much of the pathology found in sickle cell disease. Transfusion...

Red blood cell mechanical sensitivity improves in patients with sickle cell disease undergoing long-term transfusion after prolonged, subhemolytic shear exposure.
CONCLUSION: We found that long-term transfusion therapy normalizes the MS threshold above which RBC subhemolytic damage occurs after prolonged shear exposure in SCD. An important and novel finding in transfused patients with SCD was the improvement in RBC deformability in response to prolonged shear exposure over the physiologic range.

Indications for RBC Exchange Transfusion in Patients with Sickle Cell Disease: Revisited.
DISCUSSION: In the 1980s and 1990s we used the Haemonetics Corporation's V-50 machine to perform intermittent whole blood (WB) exchange to treat severe complications of sickle cell disease (SCD.) The results were excellent, as previously described [1].

Red cell transfusion and alloimmunization in sickle cell disease
Haematologica. 2021 Apr 1. doi: 10.3324/haematol.2020.270546. Online ahead of print.ABSTRACTRed cell transfusion remains a critical component of care for acute and chronic complications of sickle cell disease. Randomized clinical trials demonstrated the benefits of transfusion therapy for prevention of primary and secondary strokes and postoperative acute chest syndrome. Transfusion for splenic sequestration, acute chest syndrome, and acute stroke are guided by expert consensus recommendations. Despite overall improvements in blood inventory safety, adverse effects of transfusion are prevalent among patients with sickle ce...
