Blood transfusion remains an important therapeutic intervention in patients with sickle cell disease (SCD), aiming to both increase the oxygen carrying capacity of blood and to reduce the complications of vaso-occlusion. Simple, manual exchange and automated exchange can be effective in reducing the acute and chronic complications of SCD, and the advantages and disadvantages of each methodology mean they all have a role in different situations. Evidence for the role of emergency transfusion in the management of the acute complications of SCD, including acute pain and acute chest syndrome, comes from observational data...

Insights in the pathogenesis of vaso-occlusive crisis in patients with sickle cell disease have changed significantly in the last decade. Various laboratory and clinical evidence have provided support to the pivotal role of activated neutrophils in this process. A recent study in murine sickle cell disease indicated that the intestinal microbiota is responsible for regulating the number of aged neutrophils, a subset of neutrophils that are overly activated. Reduction of these neutrophils in vivo protected the mice from fatal TNFα-induced vaso-occlusive crisis...

OBJECTIVES: Sickle cell disease is the most common hemoglobin variant in the world and can present with recurrent vaso-occlusive painful crises. Pain control in these patients is often difficult and requires a multimodal approach. In patients with uncontrolled pain after traditional pain control methods, ketamine infusions have proven beneficial. Unfortunately, no source alone had described ketamine infusions for pediatric sickle cell patients. Our objective was to provide a thorough definitive reference for health care providers regarding the use of ketamine infusion for pain control in pediatric sickle cell painful crises...

Gliomas are highly invasive brain tumours characterised by poor prognosis and limited response to therapy. There is an ongoing debate on the therapeutic potential of vaso-modulatory interventions against glioma invasion. Prominent vasculature-targeting therapies involve tumour blood vessel deterioration and normalisation. The former aims at tumour infarction and nutrient deprivation induced by blood vessel occlusion/collapse. In contrast, the therapeutic intention of normalising the abnormal tumour vasculature is to improve the efficacy of conventional treatment modalities...

Sickle cell anemia (SCA) is an inherited blood disorder that causes painful crises due to vaso-occlusion of small blood vessels. The primary cause of the clinical phenotype of SCA is the intracellular polymerization of sickle hemoglobin resulting in sickling of red blood cells (RBCs) in deoxygenated conditions. In this review, we discuss the biomechanical and biorheological characteristics of sickle RBCs and sickle blood as well as their implications toward a better understanding of the pathophysiology and pathogenesis of SCA...

AIMS AND BACKGROUND: Mediators of adhesion become a potential new target for pharmacological therapy to struggle the complications of sickle cell disease (SCD). Several mechanisms for increased adherence have been postulated and the well-studied are CD36 and VLA4 which encoded by ITGA4. Herein, we sought to determine whether one polymorphism of CD36 namely: rs1984112 and three exons of ITGA4 (4, 5, and 6) are implicated in hemolytic status and clinical events among SCD Tunisian patients...

Quantitative cerebral blood volume (CBV) fMRI has the potential to overcome several specific limitations of BOLD fMRI. It provides direct physiological interpretability and promises superior localization specificity in applications of sub-millimeter resolution fMRI applications at ultra-high magnetic fields (7T and higher). Non-invasive CBV fMRI using VASO (vascular space occupancy), however, is inherently limited with respect to its data acquisition efficiency, restricting its imaging coverage and achievable spatial and temporal resolution...

BACKGROUND: Analgesia administration for children with vaso-occlusive crises is often delayed in the emergency department. Intranasal fentanyl (INF) has been shown to be safe and effective in providing rapid analgesia for other painful conditions. Our objective was to determine if children with a vaso-occlusive crisis (VOC) who received initial treatment with INF compared to placebo achieved a greater decrease in pain score after 20 min. PROCEDURE: This was a randomized, double-blind, placebo-controlled trial...

Pyruvate membrane crossing and its LDH-mediated conversion to lactate in cells featuring different levels of expression of membrane monocarboxylate transporters (MCT4) was probed using dissolution DNP-enhanced NMR. Hyperpolarized (13) C-1 labeled pyruvate was transferred to suspensions of rodent tumor cells CCL39. The pyruvate-to-lactate conversion rate monitored by dissolution-DNP NMR in CCL39 featuring native MCT4 expression level was lower than the rate observed for cells in which the human MCT4 gene was over-expressed...

BACKGROUND: Purtscher's retinopathy and renal cortical necrosis are two rare vaso-occlusive complications of acute pancreatitis. Purtscher's retinopathy causes sudden impairment of vision, which was first reported in a patient with head trauma. Subsequently, it was also reported as a complication of acute pancreatitis and few other clinical conditions. Acute pancreatitis also rarely causes renal cortical necrosis leading to acute kidney injury. However, the simultaneous presence of both complications is rarely reported...

Degos disease is characterized as a rare systemic vaso-occlusive disorder, although the exact pathophysiology is uncertain. Fewer than 200 patients have been reported in the literature, and only two reports describe the course of the disease during pregnancy. Here, we present the first reported case of the course of pregnancy in a woman with the systemic form of Degos disease. The patient had been diagnosed with Degos prior to pregnancy and was monitored throughout the duration of the pregnancy. Her presentation and treatment are described...

Up to now, over 1,000 experimental treatments found in cells and rodents have been difficult to translate to human ischemic stroke. Since ischemia and reperfusion, two separate stages of ischemic stroke, have different pathophysiological mechanisms leading to brain injury, a combination of protective agents targeting ischemia and reperfusion respectively may obtain substantially better results than a single agent. Normobaric hyperoxia (NBO) has been shown to exhibit neuro- and vaso-protective effects by improving tissue oxygenation when it is given during ischemia, however the effect of NBO would diminish when the duration of ischemia and reperfusion was extended...

Sickle cell anemia (SCA) is an autosomal recessive disease caused by the HBB:c.20A>T mutation that leads to hemoglobin S synthesis. The disease presents with high clinical heterogeneity characterized by chronic hemolysis, recurrent episodes of vaso-oclusion and infection. This work aimed to characterize by in silico studies some genetic modulators of severe hemolysis and stroke risk in children with SCA, and understand their consequences at the hemorheological level.Association studies were performed between hemolysis biomarkers as well as the degree of cerebral vasculopathy and the inheritance of several polymorphic regions in genes related with vascular cell adhesion and vascular tonus in pediatric SCA patients...

Sickle cell disease (SCD) is an inherited hemolytic anemia whose pathophysiology is driven by polymerization of the hemoglobin S (Hb S), leading to hemolysis and vaso-occlusive events. Inflammation is a fundamental component in these processes and a continuous inflammatory stimulus can lead to tissue damages. Thus, pro-resolving pathways emerge in order to restore the homeostasis. For example there is the annexin A1 (ANXA1), an endogenous anti-inflammatory protein involved in reducing neutrophil-endothelial interactions, accelerating neutrophil apoptosis and stimulating macrophage efferocytosis...

Sickle Cell Disease (SCD) affects approximately 100,000 Americans and due to lack of an organized treatment approach, patients with SCD pose a high economic burden on medical services. The patients with SCD have chronic bone damage from bone marrow infraction and vaso-occulsive events. These bone damages lead to chronic pain in patients with SCD. The inadwquate treatment of chronic pain in adult patients with SCD can lead to pseudo-addictive behavior and also affect their psycho-social life. There are certain barriers to adequate pain management in adult patients with SCD, namely, limited knowledge among the clinicians, inadequate assessment, concerns about addiction, and biases against opioid use...

INTRODUCTION: Preeclampsia (PE) is a life-threatening pregnancy disorder characterized by wide-spread endothelial dysfunction. Placental factors circulating in the maternal blood are believed to cause endothelial dysfunction. Our previous study identified HtrA4 as a placenta-specific serine protease that is released into the maternal circulation and significantly increased in early-onset PE. In this study, we examined the impact of HtrA4 on expression of endothelial genes related to vessel biology, using human umbilical vein endothelial cells (HUVECs) as a model...

Sickle cell disease is a chronic hematologic disease with a variety of acute, and often recurring, complications. Vaso-occlusive crisis, a unique but common presentation in sickle cell disease, can be challenging to manage. Acute chest syndrome is the leading cause of death in patients with sickle cell disease, occurring in more than half of patients who are hospitalized with a vaso-occlusive crisis. Uncommon diagnoses in children, such as stroke, priapism, and transient red cell aplasia, occur more frequently in patients with sickle cell disease and necessitate a degree of familiarity with the disease process and its management...
