Sickle cell anemia (SCA) is a serious blood disease with blood vessel changes leading to brain injury and stroke. Studies show about 11% of patients with SCA will develop obvious stroke before age 20 years, with children less than 10 years of age especially vulnerable.The main objective of the SCDMR4[State Of The Art Functional Imaging In Sickle Cell Disease] trial is to compare the gray matter cerebral blood flow, measured by MRI,[magnetic resonance imaging] ASL [Arterial Spin Labeling] perfusion before treatment begins and after the appropriate hydroxyurea dosage is reached (~ one year). Other important objectives of the SCDMR4 trial include describing the effect of hydroxyurea therapy and transfusion therapy on the functional MRI response, diffusion tensor imaging of white matter, brain function, and transcranial Doppler blood velocities.
The Primary Objective of the study is to compare the research participant's GM[Gray Matter] CBF [Cerebral Blood Flow] by ASL [Arterial Spin Labeling] techniques before and after reaching a stable hydroxyurea MTD[Maximum Tolerated Dose] (12±3 months after starting hydroxyurea).

To determine the retinal and choroidal thickness in patients with sickle cell disease compared to age, race matched population without sickle cell disease to allow a better understanding o...
The purpose of this study is to determine the safety and clinical effects of SCD-101 when given to adults with sickle cell disease. SCD-101 inhibits sickling of red blood cells containing ...
To continue studies on the two major neurological complications of sickle cell disease (SCD): namely, stroke and chronic encephalopathy.
Sickle cell disease is a genetic red blood cell disorder that can result in blocking of the small blood vessels from sickle shaped red blood cells. This causes pain, the main feature of si...
Sickle cell disease is one of the most common hereditary diseases. Most severe complications can be avoided if the disease is detected early and treated appropriately. The sickle cell dis...
Oxidative stress contributes to the complex pathophysiology of sickle cell disease. Oral therapy with pharmaceutical-grade l-glutamine (USAN, glutamine) has been shown to increase the proportion of th...
High blood cholesterol is associated with atherogenesis and endothelial dysfunction. The latter is present in hemolytic diseases, such as sickle cell anemia, whose carriers have hypocholesterolemia an...
Sickle cell disease (SCD) is the most common inheritable hematologic disorder in the USA and is associated with ischemic organ diseases. SCD-associated ischemic bowel disease is increasing being recog...
Identifying sickle cell disease patients at high risk of complications could lead to personalized treatment and better prognosis but despite many advances prediction of the clinical course of these pa...
Sickle cell disease (SCD) is a multisystem disease, and the predominant articular manifestation is osteonecrosis (ON). Total hip arthroplasty (THA) is technically challenging, and the complication rat...
One of the sickle cell disorders characterized by the presence of both hemoglobin S and hemoglobin C. It is similar to, but less severe than sickle cell anemia.
An abnormal hemoglobin resulting from the substitution of valine for glutamic acid at position 6 of the beta chain of the globin moiety. The heterozygous state results in sickle cell trait, the homozygous in sickle cell anemia.
An acute purulent infection of the meninges and subarachnoid space caused by Streptococcus pneumoniae, most prevalent in children and adults over the age of 60. This illness may be associated with OTITIS MEDIA; MASTOIDITIS; SINUSITIS; RESPIRATORY TRACT INFECTIONS; sickle cell disease (ANEMIA, SICKLE CELL); skull fractures; and other disorders. Clinical manifestations include FEVER; HEADACHE; neck stiffness; and somnolence followed by SEIZURES; focal neurologic deficits (notably DEAFNESS); and COMA. (From Miller et al., Merritt's Textbook of Neurology, 9th ed, p111)
A disease characterized by chronic hemolytic anemia, episodic painful crises, and pathologic involvement of many organs. It is the clinical expression of homozygosity for hemoglobin S.
The condition of being heterozygous for hemoglobin S.
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
