Bleeding Related Episodes, Thrombotic Events and Platelet Counts Among Immune Thrombocytopenia Patients Receiving Second Line Therapy
CONCLUSIONS: This retrospective real world evidence study compares mean platelet response and burden of both BREs and TEs in ITP patients treated with different second-line treatments. Although there were significant differences in mean platelet counts achieved with the second-line treatments, TEs were observed with similar incidence across all treatments. Patients who received splenectomy had the highest mean platelet counts and also the highest proportion of patients who experienced TEs, though differences in TEs did not reach statistical significance. Incidence proportion of patients with BREs was lower in patients trea...

Chronic Kidney Disease (CKD) in the U.S. Hemophilia Population: A Cohort Study
Conclusions: In this interim analysis of an ongoing national prospective cohort study, older men with moderate to severe hemophilia commonly report risk factors for CKD, including HTN (51.5%), DM, viral infection, and potential renal damaging medication use. Only 11.6% had CVD. Urological symptoms were also common, including hematuria and obstructive symptoms with urination.In our cohort, 11.4% met the definition of CKD, defined as the presence of either kidney damage or GFR < 60 ml/min/1.73 m2 for ≥ 3 months. The distribution of GFR values appeared similar to the general population. As with risk factors associated w...

Inherited Thrombophilia and the Risk of Arterial Ischemic Stroke: A Systematic Review and Meta-Analysis
Conclusions: Our results suggest that inherited thrombophilias including FVL, PTM, PCD, and PSD are associated with an increased risk of arterial ischemic stroke, particularly in young patients. The association with FVL and PTM is stronger in the homozygous than in the heterozygous state, suggesting a potential dose-response relationship and causal role for inherited thrombophilias. The implications of these findings with respect to the evaluation and management of patients with ischemic stroke require further investigation.DisclosuresCrowther: Alnylam: Equity Ownership; Daiichi Sankyo: Membership on an entity's Board of D...

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...

Efficacy and Safety of Prothrombin Complex Concentrate (PCC) for Direct Oral Anticoagulant Reversal: A Single Institutional Experience
ConclusionIn this cohort, 80% of pts demonstrated clinical stability/improvement of hemorrhage. All pts were able to undergo surgical procedures; however 17% required additional FFP to achieve hemostasis. Thromboembolism occurred in 12% of patients. No deaths could definitely be attributed to 4PCC; however, 30% of deaths could be attributable to the underlying hemorrhagic episode.DisclosuresNo relevant conflicts of interest to declare.

Benefits and Limitations of Long-Term Eculizumab Treatment for Paroxysmal Nocturnal Hemoglobinuria (PNH): Real-World Data from Large Cohort Study in Russia
Conclusions: The results of the study show both the high efficacy and limitations of treatment with eculizumab for PNH in real-world practice. Prospectively confirmed significant improvement of the overall survival on eculizumab stress the need for faster and wider access to costly therapy. Nevertherless, a number of limitations, including BTH and extravascular hemolysis, lack of control of bone marrow failure and further clonal evolution, determine the relevance of next-generation complement inhibitors and risk-adjusted allogeneic HSCT as a curative option.DisclosuresKulagin: Alexion Pharmaceuticals, Inc: Consultancy, Honoraria.

Reassessing the Need for Pre-Operative Transfusions in Sickle Cell Disease Patients with a High Baseline Hemoglobin
Conclusion: Patients with SCD and a baseline hemoglobin ≥90 g/L who receive a pre-operative top-up transfusion have an increased risk of post-operative complications compared to those who are not transfused. In low and medium risk surgeries, a policy of withholding transfusions for such patients may be considered. Prospective studies validating these findings are needed.DisclosuresNo relevant conflicts of interest to declare.

The Role of Hydroxyurea to Prevent Silent Stroke in Sickle Cell Disease: Systematic Review and Meta-Analysis
Chronic blood transfusions are standard of care for stroke prevention in sickle cell disease. We evaluated hydroxyurea's efficacy in preventing silent stroke. We searched for randomized controlled trials (RCTs) and observational studies on Pubmed, CENTRAL, Embase, and Web of Science without using language/time limits. Eligible studies compared hydroxyurea with transfusions or observation to prevent silent stroke. This systematic review adheres to the Cochrane guidelines. Data were pooled using random effects model using STATA to perform meta-analysis. Methodological quality of RCTs was investigated using the Cochrane risk ...

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...

Brain Magnetic Resonance Imaging and Angiography Findings in Ugandan Children with Sickle Cell Anemia; A Cross Sectional Study
ConclusionsBrain injury in Uganda children with SCA begins early in childhood and becomes a common finding during later childhood. Early screening for stroke and intervention therapy is warranted to prevent sickle brain vasculopathy initiated early after diagnosis. The risk factors for such early brain injury should be investigated.DisclosuresNo relevant conflicts of interest to declare.

Coagulation Profile of Sickle Cell Patients with Leg Ulcers
CONCLUSIONSIn SCD patients with leg ulcers, PC and PS levels are significantly lower than in SCD patients without leg ulcers. Additionally, in SCD patients with leg ulcers, there is a trend towards decreased levels of AT III and increased LA positivity. FVL and prothrombin gene mutations were rare in our cohort, consistent with the general population. The above findings did not correlate clinically with a history of DVT/PE in the same population.Our results of decreased NOACs confirm previous reports from our group that demonstrated similar findings. Of greater significance, however, is our finding that sickle cell patient...

Relationship between Hemolytic Index Early in Life with Development of Abnormal Transcranial Doppler Velocities in Pediatric Patients with Sickle Cell Anemia
Conclusions: This retrospective study noted an increased risk for development of an abnormal or conditional TCD with an increased HI. The addition of hemoglobin to the HI to form HHI showed an elevated risk for abnormal or conditional TCD to the same degree as HI itself. These results could offer an additional tool in the evaluation of the pediatric SCA population, although these results would benefit from a prospective look. Further look into a possible association between HI and other SCD related complications such as stroke and acute chest syndrome could provide further information for the treating team for the overall ...

Mean Platelet Volume Predicts Mortality in Sickle Cell Disease
Conclusion:MPV is an independent biomarker predicting disease severity and probability of death in patients with sickle cell disease with a strong correlation especially in pediatric age group. Although there was no statistical significance across age groups, the variation of MPV for each patient with age needs to be studied for better understanding. Hydroxyurea a known disease-ameliorating agent is associated with lower MPV values in pediatric age group. This effect is independent of the levels of fetal hemoglobin and may be due to anti-inflammatory effect of hydroxyurea or decreased platelet consumption.Figure.Disclosure...

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.
