BACKGROUND: Sickle cell disease is a genetic chronic haemolytic and pro-inflammatory disorder. The clinical manifestations of sickle cell disease result from the presence of mutations on the beta globin genes that generate an abnormal haemoglobin product (called haemoglobin S) within the red blood cell. Sickle cell disease can lead to many complications such as acute chest syndrome, stroke, acute and chronic bone complications (including painful vaso-occlusive crisis, osteomyelitis, osteonecrosis and osteoporosis)...

Sickle cell disease is a risk factor for cerebrovascular accidents in the pediatric population. This risk is compounded by hypoxemia. Cyanotic congenital heart disease can expose patients to prolonged hypoxemia. To our knowledge, the long-term outcome of patients who have combined sickle cell and cyanotic congenital heart disease has not been reported. We retrospectively reviewed patient records at our institution and identified 5 patients (3 girls and 2 boys) who had both conditions. Their outcomes were uniformly poor: 4 died (age range, 12 mo-17 yr); 3 had documented cerebrovascular accidents; and 3 developed ventricular dysfunction...

BACKGROUND: Sickle cell disease is one of the commonest severe monogenic disorders in the world, due to the inheritance of two abnormal haemoglobin (beta globin) genes. Sickle cell disease can cause severe pain, significant end-organ damage, pulmonary complications, and premature death. Stroke affects around 10% of children with sickle cell anaemia (HbSS). Chronic blood transfusions may reduce the risk of vaso-occlusion and stroke by diluting the proportion of sickled cells in the circulation...

Progressive neurovasculopathy in children with sickle cell disease (SCD) results in decreased cognitive function and quality of life (QoL). Hematopoietic cell transplant (HCT) is believed to halt progression of neurovasculopathy. Quantitative analysis of T2-weighted fluid attenuated inversion recovery (FLAIR) MRI for white matter hyperintensity (WMH) burden provides a meaningful estimate of small vessel cerebrovascular disease. We asked if quantitative analysis of WMH could complement standardized clinical assessment of MRI/MRA for assessing SCD CNS vasculopathy pre- and post-HCT...

Sickle cell anemia (SCA) is a genetic disorder resulting in reduced oxygen carrying capacity and elevated stroke risk. Pseudo-continuous arterial spin labeling (pCASL) measures of cerebral blood flow (CBF) may have relevance for stroke risk assessment; however, the effects of elevated flow velocity and reduced bolus arrival time (BAT) on CBF quantification in SCA patients have not been thoroughly characterized, and pCASL model parameters used in healthy adults are often applied to patients with SCA. Here, cervical arterial flow velocities and pCASL labeling efficiencies were computed in adults with SCA (n = 19) and age- and race-matched controls without sickle trait (n = 7) using pCASL in sequence with phase contrast MR angiography (MRA)...

OBJECTIVES: Sickle cell disease (SCD) is a global health concern associated with high childhood morbidity and mortality; in Oman, the prevalence of SCD is 0.2%. Public awareness of SCD and the need for premarital screening (PMS) are essential to reduce the incidence of this disease. This study aimed to assess awareness of and beliefs regarding SCD and PMS among Omanis in a primary healthcare setting. METHODS: This cross-sectional study took place in five health centres located in Al-Seeb Province, Muscat, Oman, between June and August 2015...

Sickle cell disease is an inherited haemoglobinopathy that can affect multiple organs and systems. The most common neurological complication in sickle cell disease is stroke and silent cerebral infarcts. Peripheral nervous system involvement has been described but is exceedingly rare. Herein, we describe the case of a young woman who presented with acute flaccid paralysis and sensory loss of the left lower extremity in the context of a painful vasoocclusive crisis which resolved rapidly after receiving an emergency automated red cell exchange transfusion...

BACKGROUND: While blood transfusions are commonly used for prophylaxis and treatment for acute chest syndromes and strokes in sickle cell patients, accumulation of excess iron resulting in secondary hemochromatosis remains a rare disease. Chelation is the mainstay for preventing and treating iron overload to deter potential end-organ damages; it is rare when therapy fails. CASE REPORT: A 52-year-old African American woman with chronic anemia secondary to sickle cell anemia and history of multiple blood transfusions presented with elevated serum ferritin (8000 ng/mL) and bilirubin (16...

BACKGROUND: Stroke is a severe clinical disorder in sickle cell disease (SCD), and few studies have evaluated transcranial Doppler (TCD) flow velocities in hemoglobin SC disease (HbSC). The guidelines for stroke risk are based on evaluations in sickle cell anemia (SCA) or HbS/β thalassemia. PROCEDURE: In this study, we compare cerebral blood flow in patients with SCD stratified by genotypes. A total of 1,664 pediatric patients with SCD underwent TCD velocity screening, and the time-averaged maximum mean velocity (TAMM) was determined in the middle cerebral artery (MCA), anterior cerebral artery (ACA), and distal intracranial internal carotid artery (ICA) ...

Since 1998, the National Institutes of Health has funded 5 randomized controlled trials (RCTs) for primary and secondary prevention of strokes in children with sickle cell anemia (SCA). In a systematic fashion, these trials have significantly advanced the care of children with SCA. In the absence of an RCT, clinicians are often compelled to make decisions at the bedside, based on experience, observational studies, and principles of hematology. We will provide an initial example that describes how a team-based, learning collaborative developed a multisite standard care protocol with a low budget (<$10 000 per year) to overcome the intrinsic limitations of advancing the care of neurologic complications in sickle cell disease (SCD)...

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...

Overt ischaemic stroke is one of the most devastating complications in children with sickle cell disease (SCD). The compensatory response to anaemia in SCD includes an increase in cerebral blood flow (CBF) by accessing cerebrovascular dilatory reserve. Exhaustion of dilatory reserve secondary to anaemic stress may lead to cerebral ischaemia. The purpose of this study was to investigate CBF and cerebrovascular reactivity (CVR) using magnetic resonance imaging (MRI) in children with SCD and to correlate these with haematological markers of anaemia...

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...

Sheehan's syndrome (SS) is one of the pituitary disorders caused by severe blood loss during childbirth leading to necrosis of the pituitary gland. Diagnosis is made following severe haemorrhage, failure to produce milk and failure to menstruate. Rare in countries with good obstetric care, SS is still frequent in those countries with poor healthcare services. The majority of papers published on SS do not mention psychological or neuropsychological sequelae. Of those that do, mood disorders are sometimes reported and occasionally cognitive problems are noted, typically attention, memory or executive deficits...

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...

Stroke is a leading cause of disability and mortality worldwide. Ultrasound is a real-time imaging technique that is inexpensive, portable, non-invasive, and safe, with high diagnostic accuracy. Ultrasonic imaging can provide useful direct and indirect information about the characteristics of various vessels in the both intracranial and extracranial segments. Areas covered: In this review, we will discuss multimodal applications of ultrasonic imaging in stroke prevention and management including checking carotid intima-media thickness progression, evaluating the plaque morphology, calibrating the degree of stenosis, detecting the presence of patent foramen ovale, monitoring microembolization, and screening for stroke risk in patients with sickle cell disease...
