Hydroxyurea reduces cerebral metabolic stress in patients with sickle cell anemia
Chronic transfusion therapy (CTT) prevents stroke in selected patients with sickle cell anemia (SCA). We have shown that CTT mitigates signatures of cerebral metabolic stress, reflected by elevated oxygen extraction fraction (OEF), which likely drives stroke risk reduction. The region of highest OEF falls within the border zone, where cerebral blood flow (CBF) nadirs; OEF in this region was reduced after CTT. The neuroprotective efficacy of hydroxyurea (HU) remains unclear. To test our hypothesis that patients receiving HU therapy have lower cerebral metabolic stress compared with patients not receiving disease-modifying t...

Sickle Cell Disease Subjects Have a Distinct Abnormal Autonomic Phenotype Characterized by Peripheral Vasoconstriction With Blunted Cardiac Response to Head-Up Tilt
Conclusion We have shown that SCD subjects are much more likely than non-SCD subjects to have impaired cardiac, but intact peripheral responses to orthostatic stress induced by HUT. These abnormal responses are associated with low baseline cardiac parasympathetic activity, independent of hemoglobin level. The classification of autonomic phenotypes based on HUT response may have potential use for predicting disease severity, guiding and targeting treatments/interventions to alleviate the risk of adverse outcomes in SCD. Ethics Statement All experiments were conducted at Children’s Hospital Los Angeles (CHLA). The ...

Haploidentical Bone Marrow Transplantation with Post-Transplantation Cyclophosphamide Plus Thiotepa Improves Donor Engraftment in Patients with Sickle Cell Anemia: Results of an International Learning Collaborative
Sickle cell disease (SCD) has evolved from a life-threatening condition in early childhood to a chronic disease in adults [1,2]. Improved supportive care [3], use of hydroxyurea therapy [4], and regular blood transfusion therapy for primary [5] and secondary [6] stroke prevention have resulted in improved childhood clinical outcomes and survival. Approximately 99% of all children born with SCD are expected to live to adulthood [7,8]. The most feared complication in children with SCD is stroke [9].

Practice Patterns in the Use of MRI/MRA and Chronic Transfusion Therapy for Monitoring and Treatment of Stroke in Pediatric Patients with Sickle Cell Anemia
Conclusions: The results of the DISPLACE practice patterns survey suggested nearly universal adoption of CRCT for children with abnormal TCD and prior overt stroke across sites. The use of MRI/MRA in detecting potential cerebrovascular abnormalities in the absence of clinical neurologic symptoms and for monitoring patients on CRCT was much more variable, which likely reflects the minimal amount of guidance for the use of MRI/MRA in SCA. Notably, a number of sites were using MRI/MRA to screen pediatric patients for cerebrovascular abnormalities and to monitor patients on CRCT. The variability in responses for MRI/MRA highli...

Middle Cerebral Artery Velocities Are Inversely Related to Hemoglobin Levels and Acutely Drop in Response to RBC Transfusion: Implications for Stroke Screening in SCD
DiscussionThese data show a striking relationship between anemia and TCD velocity, and that RBC transfusion can alter MCA velocity. Even an 11% increase in hemoglobin such as that seen in the low-responder in Figure 3 could change a patient classification from high-risk to conditional TCD. These data also show the significant sensitivity of MCA velocity to the depth of measurement (Figure 2 & 3). The investigators in the STOP study went to extreme ends to standardize these measurements. Nonetheless, TCD measures may not be done with such rigor in clinical settings. It is clear that standard TCD screening has been of tr...

Transfusion Therapy in a Multi-Ethnic Sickle Cell Population Real-World Practice. a Preliminary Data Analysis of Multicentre Survey
Conclusion. The transfusional approach is similar in HbSS, b°-thal/HbS and b+-thal/HbS patients with similar indications, prevalently VOCs and anemia. The significant higher age in Caucasian cohort and the consequent long term follow up could be the cause of variable therapeutic approach observed, however Hydroxycarbamide seemed to be the therapy more frequently used and finally suggested to manage chronic manifestations.Figure.DisclosuresOriga: Apopharma: Honoraria; Novartis: Honoraria; Bluebird Bio: Consultancy; Cerus Corporation: Research Funding.

Results from the Displace Consortium: Practice Patterns on the Use of Transcranial Doppler Screening for Risk of Stroke in Children with Sickle Cell Anemia
Conclusions: Nearly all DISPLACE sites order TCD screening annually, as recommended in the guidelines, with some ordering screening more frequently. A few sites did not report initiation of CRCT per STOP protocol for abnormal TCD results; however, over half of the sites reported following up with an MRI/MRA, which may suggest evaluating for vasculopathy prior to CRCT. Some sites reported beginning HU therapy for abnormal results; this may reflect consideration of patients for whom CRCT is not possible, but data were not collected for confirmation. Interestingly, results suggest a reliance on MRI/MRA since sites commonly re...

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.

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 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...

Cerebral vasculopathy in children with sickle cell disease: Key issues and the latest data.
Abstract Cerebral vasculopathy is a common and severe complication of sickle cell disease in children. The pathophysiology consists of progressive damage to the basal intracranial arteries and cerebral microcirculation, while chronic anemia worsens exposure to cerebral hypoxia. It results in stroke and subclinical or poorly symptomatic ischemic lesions. Many clinical, biological, and radiological risk factors have been identified. The prevention strategy through systematic transcranial Doppler screening of large-vessel vasculopathy has revolutionized the management of this disease and has greatly decreased the ris...

How I manage sickle cell patients with high transcranial doppler results
Summary Stroke is one of the most severe complications to affect children with sickle cell anaemia (SCA). Transcranial doppler (TCD) is an accurate and non‐invasive method to determine stroke risk. Randomised controlled trials have demonstrated the efficacy of chronic transfusion therapy in stroke prevention based on risk stratification determined by TCD velocities. This has led to the regular use of TCD monitoring for children with SCA in order to determine stroke risk. Significant resource allocation is necessary to facilitate training, quality assurance and failsafe arrangements for non‐attenders. In a subgroup of p...

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...

Blood transfusion services for patients with sickle cell disease in Nigeria
Conclusion Current efforts of Nigerian public hospitals to provide safe blood and CTT fall short of best practice. Provision of apheresis machines, improvement of voluntary non-remunerated donor drive, screening for red cell antigens and antibodies, and availability of iron chelators would significantly improve SCD care in Nigeria.

Transfusion therapy for sickle cell disease
The clinical presentations of sickle cell disease include acute pain, acute chest syndrome, stroke and acute anaemia and blood transfusion therapy can be used effectively in the emergency setting for the treatment of many of these complications. Long‐term blood transfusion therapy is also used for the prevention of disease complications with most evidence for its use in primary stroke prevention. Transfusion can be given as a simple or top‐up transfusion or as an exchange transfusion and donor red cells should be haemoglobin S negative and as a minimum matched for ABO, full Rh and Kell type. Repeated transfusions lead ...

How I treat and manage strokes in sickle cell disease
Neurologic complications are a major cause of morbidity and mortality in sickle cell disease (SCD). In children with sickle cell anemia, routine use of transcranial Doppler screening, coupled with regular blood transfusion therapy, has decreased the prevalence of overt stroke from ~11% to 1%. Limited evidence is available to guide acute and chronic management of individuals with SCD and strokes. Current management strategies are based primarily on single arm clinical trials and observational studies, coupled with principles of neurology and hematology. Initial management of a focal neurologic deficit includes evaluation by...

Hydroxyurea use in prevention of stroke recurrence in children with sickle cell disease in a developing country: A cost effectiveness analysis
We undertook a cost effectiveness analysis (CEA) of hydroxyurea (HU) in preventing stroke recurrence and/or death. We followed 43 children with sickle cell disease from 2000 to 2009 after having a first clinical stroke, of whom 10 opted for HU therapy. HU use led to decreased stroke recurrence and death without significantly increasing the annual cost of care per patient (J$83,250 vs. J$76,901, P = 0.491). The incremental cost effectiveness ratio (ICER) for prevention of stroke recurrence amounted to J$169,238 (US$1,900), while that for death prevention equalled J$635,843 (US$7,140). HU may be recommended when safe and...

In Context News in brief
Stroke and silent cerebral infarcts are common in children with sickle cell anaemia. Although the incidence of silent cerebral infarcts can be reduced with regular blood transfusions, it is unknown whether regular transfusions can prevent the recurrence of an infarct (stroke or new or enlarged silent cerebral infarction). In a multicentre, randomised, single-blind, controlled trial of 196 children aged 5 to 15 years with sickle cell anaemia who had silent cerebral infarcts, 6 of 99 (6%) children who received transfusion therapy had an end-point event (one had stroke and five had new or enlarged silent cerebral infarcts) ov...
