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.

Analysis of the Safety Profile of Direct Oral Anticoagulants Using the FDA Adverse Event Reporting System
Conclusion:Our analysis found that among DOACs rates of breakthrough VTE were significantly higher with rivaroxaban, and that reported rates of ischemic stroke were significantly higher with dabigatran. While no DOACs have been compared against each other in prospective trials, post-marketing reports have suggested that different safety profiles exist among DOACs, a finding reiterated by our analysis. The significantly higher rate of VTE reported with rivaroxaban as compared to other DOACs has not previously been described to the best of our knowledge and deserves further analysis. The two methods of comparing the anticoag...

Real-World Comparisons of Cardiovascular Events between Different Tyrosine Kinase Inhibitors Among Patients with Chronic Myeloid Leukemia
CONCLUSION: CP-CML patients treated with different TKIs (ponatinib, bosutinib, imatinib, dasatinib, and nilotinib) did not have different incidence of cardiovascular events (MACE, AOEs, VTEs) in this small cohort of real-world patients with ≥6-month of follow-up. The results were consistent among patients with prior use of one and two TKI types.DisclosuresLevy: Takeda (Millennium Pharmaceuticals, Inc.): Consultancy. Xie: STATinMED Research: Employment.

Transcranial Doppler Screening Adherence Among Children with Sickle Cell Anemia Seen in the Emergency Department
Conclusion: Patients with SCA who present to the ED and are nonadherent to TCD screening guidelines are less likely to have had a recent hematology clinic visit. Therefore, the ED may be an important location for identifying patients lost to regular clinic follow-up in need of a TCD. An intervention that specifically targets this patient population will likely improve TCD screening rates and stroke prevention.Figure.DisclosuresNo relevant conflicts of interest to declare.

Comprehensive Sickle Cell Disease Management Is Associated with Superior Grade Attainment and High School Graduation Rates
Discussion: In this cohort, a high percentage of patients (86.7%) graduated or were on track to graduate from high school. In the United States, approximately 90% of patients with SCD are African American. All patients analyzed here were African American. With this in mind, ACHSCDP patients' graduation rate compares favorably to estimated graduation rates across the US general population (84%), the U.S. African America population (76%), the U.S. sickle cell patient population (71%), the Ohio general population (84%), and the Ohio African American population (68%).The higher graduation rate among children at the ACHSCDP is ...

Characterizing a Population with Severe Manifestations of Sickle Cell Disease Using U.S. Real-World Evidence
ConclusionsBased on this contemporary real-world evidence from the U.S. setting, a substantial proportion of patients with SCD experience a diverse set of severely debilitating complications of the disease, as well as other co-morbidities associated with the disease. The high rate of comorbidities across all age groups and overrepresentation of patients younger than 30 years of age (relative to age distribution of general U.S. population) indicate that patients with SCD still experience significant morbidity and early mortality with current standard medical care. Given the notable heterogeneity of the clinical manifestatio...

GpIb{alpha}-VWF blockade restores vessel patency by dissolving platelet aggregates formed under very high shear rate in mice
Interactions between platelet glycoprotein (Gp) IIb/IIIa and plasma proteins mediate platelet cross-linking in arterial thrombi. However, GpIIb/IIIa inhibitors fail to disperse platelet aggregates after myocardial infarction or ischemic stroke. These results suggest that stability of occlusive thrombi involves additional and as-yet-unidentified mechanisms. In the present study, we investigated the mechanisms driving platelet cross-linking during occlusive thrombus formation. Using computational fluid dynamic simulations and in vivo thrombosis models, we demonstrated that the inner structure of occlusive thrombi is heteroge...

Rates, management, and outcome of rivaroxaban bleeding in daily care: results from the Dresden NOAC registry
Worldwide, rivaroxaban is increasingly used for stroke prevention in atrial fibrillation and treatment of venous thromboembolism, but little is known about rivaroxaban-related bleeding complications in daily care. Using data from a prospective, noninterventional oral anticoagulation registry of daily care patients (Dresden NOAC registry), we analyzed rates, management, and outcome of rivaroxaban-related bleeding. Between October 1, 2011, and December 31, 2013, 1776 rivaroxaban patients were enrolled. So far, 762 patients (42.9%) reported 1082 bleeding events during/within 3 days after last intake of rivaroxaban (58.9% mino...

Risk of venous and arterial thrombotic events in patients diagnosed with superficial vein thrombosis: a nationwide cohort study
We examined this in a nationwide population-based setting during a period when SVT was not treated routinely with anticoagulants. The Danish National Registry of Patients, covering all Danish hospitals, was used to identify 10 973 patients with a first-time diagnosis of SVT between 1980 and 2012. A comparison cohort of 515 067 subjects, matched by age, gender, and calendar year, was selected from the general Danish population. Outcomes were venous thromboembolism, acute myocardial infarction, ischemic stroke, and death. During median follow-up of 7 years, the incidence rate of venous thromboembolism was 18.0/1000 person-ye...

Management and clinical outcomes in patients treated with apixaban vs warfarin undergoing procedures
Using data from ARISTOTLE, we describe the periprocedural management of anticoagulation and rates of subsequent clinical outcomes among patients chronically anticoagulated with warfarin or apixaban. We recorded whether (and for how long) anticoagulant therapy was interrupted preprocedure, whether bridging therapy was used, and the proportion of patients who experienced important clinical outcomes during the 30 days postprocedure. Of 10 674 procedures performed during follow-up in 5924 patients, 9260 were included in this analysis. Anticoagulant treatment was not interrupted preprocedure 37.5% of the time. During the 30 day...

Long-term treatment follow-up of children with sickle cell disease monitored with abnormal transcranial Doppler velocities
We present the long-term follow-up of SCA children from the Créteil newborn cohort (1992-2012) detected at risk by TCD and placed on chronic transfusions. Patients with normalized velocities and no stenosis were treated with hydroxyurea, known to decrease anemia and hemolytic rate. Trimestrial Doppler was performed and transfusions restarted immediately in the case of reversion to abnormal velocities. Patients with a genoidentical donor underwent transplant. Abnormal time-averaged maximum mean velocities (TAMMV) ≥200 cm/s were detected in 92 SCA children at a mean age of 3.7 years (range, 1.3-8.3 years). No strok...

Intracranial hemorrhage in patients with atrial fibrillation receiving anticoagulation therapy
We investigated the frequency and characteristics of intracranial hemorrhage (ICH), the factors associated with the risk of ICH, and outcomes post-ICH overall and by randomized treatment. We identified patients with ICH from the overall trial population enrolled in the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation trial who received ≥1 dose of the study drug (n = 18 140). ICH was adjudicated by a central committee. Cox regression models were used to identify factors associated with ICH. ICH occurred in 174 patients; most ICH events were spontaneous (71.7%) versus traumatic (28.3...

The role of ADAMTS13 testing in the diagnosis and management of thrombotic microangiopathies and thrombosis
ADAMTS13 (a disintegrin and metalloproteinase with thrombospondin type 1 motif, 13) is a metalloprotease responsible for cleavage of ultra-large von Willebrand factor (VWF) multimers. Severely deficient activity of the protease can trigger an acute episode of thrombotic thrombocytopenic purpura (TTP). Our understanding of the pathophysiology of TTP has allowed us to grasp the important role of ADAMTS13 in other thrombotic microangiopathies (TMAs) and thrombotic disorders, such as ischemic stroke and coronary artery disease. Through its action on VWF, ADAMTS13 can have prothrombotic and proinflammatory properties, not only ...

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...
