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]. PMID: 31882437 [PubMed - in process]

Curing hemoglobinopathies: challenges and advances of conventional and new gene therapy approaches.
Inherited hemoglobin disorders, including beta-thalassemia (BT) and sickle-cell disease (SCD) are the most common monogenic diseases worldwide, with a global carrier frequency of over 5%. With migration they are becoming more common worldwide, making their management and care an increasing concern for health care systems.BT is characterized by an imbalance in the α/β-globin chain ratio, ineffective erythropoiesis, chronic hemolytic anemia, and compensatory haemopoietic expansion. Globally, there are over 25,000 births each year with transfusion-dependent thalassemia (TDT). The current available treatment f...

Cerebral Venous Thrombosis after Red Blood Cell Transfusion for the Treatment of Iron Deficiency Anemia
A 57-year-old male presented with generalized seizure who received red blood cell (RBC) transfusion for the treatment of iron deficiency anemia (IDA). Neuroradiological findings revealed cerebral venous thrombosis (CVT) on the left frontal vein. He received anticoagulants, anticonvulsants, and iron supplements. He discharged without any neurological deficit. It should be noted that RBC transfusion might increase the risk of CVT in patients with IDA.

Infant with protein C deficiency and stroke in the setting of iron deficiency anemia
We report an 18 ‐month‐old infant with ischemic stroke, neurocognitive impairment, and psychomotor retardation in the setting of severe iron deficiency anemia. Although an uncommon outcome in anemic children, stroke is important to consider as a cause for developmental delay in children with iron deficiency ane mia.

Pericytes in Hereditary Hemorrhagic Telangiectasia.
Authors: Galaris G, Thalgott JH, Lebrin FPG Abstract Hereditary hemorrhagic telangiectasia (HHT) is a genetic disorder characterized by multi-systemic vascular dysplasia affecting 1 in 5000 people worldwide. Individuals with HHT suffer from many complications including nose and gastrointestinal bleeding, anemia, iron deficiency, stroke, abscess, and high-output heart failure. Identification of the causative gene mutations and the generation of animal models have revealed that decreased transforming growth factor-β (TGF-β)/bone morphogenetic protein (BMP) signaling and increased vascular endothelial growth factor ...

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...

Efficacy and safety of erythropoietin and iron therapy to reduce red blood cell transfusion in surgical patients: a systematic review and meta-analysis
ConclusionAdministration of ESA and iron therapy reduced the risk for RBC transfusion compared with iron therapy alone in patients undergoing cardiac and non-cardiac surgery. Nevertheless, publication bias and heterogeneity reduces the confidence of the finding. Although the analysis was probably under-powered for some outcomes, no difference in the incidence of serious adverse events was observed with ESA and iron compared with iron alone. Further large prospective trials are required to confirm these findings.

Associations of Anemia With Outcomes in Patients With Spontaneous Intracerebral Hemorrhage: A Meta-Analysis
Conclusions: Anemia on admission was associated with higher mortality and an increased risk of poor outcome in patients with ICH. However, the results were limited by the high heterogeneity of included studies. Prospective, multi-center or population-based, large sample cohort studies are needed in the future. Introduction Intracerebral hemorrhage (ICH) is the second most common cause of stroke and a highly lethal disease (1), which still lacks effective therapeutic interventions (2, 3). Although age, baseline ICH volume and neurological status on admission are well-known predictors of outcome of ICH (4), none of 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 ...

Overview of Pulmonary Arteriovenous Malformations and Hereditary Hemorrhagic Telangiectasia
Pulmonary arteriovenous malformations (PAVMs) are rare and commonly caused by an autosomal dominant disorder known as hereditary hemorrhagic telangiectasia (HHT). HHT is an often-missed vascular disorder causing symptoms of epistaxis, mucosal telangiectasia, AVMs, hemoptysis, dyspnea, and iron deficiency anemia. Large AVMs in the lungs, liver, and brain can be life-threatening. Early diagnosis and intervention are imperative to prevent serious complications of massive hemoptysis, stroke, cerebral abscess, and gastrointestinal bleeding.

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.
