Prospective Evaluation Of Chronic Organ Damage In Adult Sickle Cell Patients. A Seven ‐Year Follow‐Up Study
In conclusion, 62% of the sickle cell patients in this prospective cohort study developed a new SCD‐related complication in a comprehensive care setting within 7 years of follow‐up. Although the hospital admission rate for VOC remained stable, multiple forms of organ damage increased substantially. These observations underline the need for continued screening for organ damage in all adult patients with SCD. This article is protected by copyright. All rights reserved.

Silent infarcts in sickle cell disease occur in the border zone region and are associated with low cerebral blood flow
Silent cerebral infarcts (SCIs) are associated with cognitive impairment in sickle cell anemia (SCA). SCI risk factors include low hemoglobin and elevated systolic blood pressure; however, mechanisms underlying their development are unclear. Using the largest prospective study evaluating SCIs in pediatric SCA, we identified brain regions with increased SCI density. We tested the hypothesis that infarct density is greatest within regions in which cerebral blood flow is lowest, further restricting cerebral oxygen delivery in the setting of chronic anemia. Neuroradiology and neurology committees reached a consensus of SCIs in...

Role of Automated Red Cell Exchange in Acute and Chronic Complications of Sickle Cell Disease
Discussion. Our study shows that red cell exchange is an effective treatment modality for patients with sickle cell disease. It contributes to improvement in weight, increase in Hb and Hct and decrease in wbc, plt, HbS% and iron overload. It also decreases inpatient and ED admissions. The procedure is safe and tolerable with minimal complications. Long term studies are needed study the efficacy of this treatment modality and its contribution to improvement of quality of life and life expectancy in sickle cell disease patients.DisclosuresNo relevant conflicts of interest to declare.

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...

Metal ion chelation enhances tissue plasminogen activator (tPA)-induced thrombolysis: an in vitro and in vivo study
AbstractStroke is the third leading cause of death in the United States and the leading cause of adult disability. Despite enormous research efforts including many clinical trials, tissue plasminogen activator (tPA) remains the only FDA-approved treatment for acute ischemic stroke. Unfortunately, only 1 –3% of stroke patients in the US receive this therapy because of the narrow time window and severe side effects for using tPA. The most deadly and damaging side effect is the risk of intracranial bleeding or hemorrhage. For that reason, the dose of tPA and its overall administration are under tigh t control, which may com...

A multicenter, randomized, active-controlled study to investigate the efficacy and safety of intravenous ferric carboxymaltose in patients with iron deficiency anemia.
CONCLUSION: Two 750-mg FCM infusions are safe and superior to oral iron in increasing Hb levels in IDA patients with inadequate oral iron response.

Outcomes of Unrelated Donor Stem Cell Transplant with Post-Transplant Cyclophosphamide for Graft-versus-Host Disease Prophylaxis in Patients with Severe Sickle Cell Disease
Sickle cell disease (SCD) is a hemoglobinopathy affecting 1 in every 500 African American newborns and an estimated 100,000 persons in the United States [1]. Vascular occlusion caused by the sickled RBCs leads to decreased perfusion in target organs and manifests clinically as vaso-occlusive pain crisis, stroke (cerebral infarction), pulmonary restrictive disease, and pulmonary hypertension [2]. Despite advances in supportive care, including the use of hydroxyurea (HU), RBC transfusion, and iron chelation therapy, patients with SCD continue to experience considerable morbidity and mortality in their lifetime.

Degree of anemia, indirect markers of hemolysis, and vascular complications of sickle cell disease in Africa
In conclusion, severe anemia at steady state in SCD patients living in West and Central Africa is associated with elevated TRV, microalbuminuria, and leg ulcers, but these vascular complications are not independently associated with indirect markers of increased hemolysis. Other mechanisms leading to anemia, including malnutrition and infectious diseases, may also play a role in the development of SCD vasculopathy.

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...

Automated RBC exchange compared to manual exchange transfusion for children with sickle cell disease is cost-effective and reduces iron overload.
CONCLUSION: Erythrocytapheresis reduces iron overload and allows a longer interval between procedures without a higher RBC requirement from the second year on aRBX. The cost did not increase as estimated in our Belgian Health Care System.

Clinical Relevance of Clonal Hematopoiesis in the Oldest-Old Population: Analysis of the "Health and Anemia" Study
Conclusion. Clonal hematopoiesis was associated with reduced survival in an oldest-old population. Specific mutational profiles define different risks of developing MDS and inflammatory/vascular diseases. Non mutational factors, such as early changes in red blood cell indices, may improve the capability to identify patients at increased risk of developing myeloid cancers.DisclosuresMeggendorfer: MLL Munich Leukemia Laboratory: Employment.

B0 Vs. Non-B0 Genotype: Differences in Non-Transfusion-Dependent Thalassemia Patients
Conclusions: Heart remodelling related to a high cardiac output state cardiomyopathy was more pronounced in patients with homozygous β°/β° genotype. Osteoporososis was significantly more frequent in patients with homozygous β°/β° genotype, treated for more than two-thirds with DFO therapy. These data support the knowledge of different phenotypic groups in the management of NTDT patients.TableDisclosuresPepe: Chiesi Farmaceutici S.p.A., ApoPharma Inc., and Bayer: Other: No profit support.
