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).

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...
Sickle cell disease comprises a group of genetic haemoglobin disorders. The predominant symptom associated with sickle cell disease is pain resulting from the occlusion of small blood vessels by abnor...
Sickle cell disease is an inherited hemolytic disease with systemic complications. These complications significantly impact the patients' quality of life. There are characteristic radiological finding...
Sickle cell disease affects more than 100,000 individuals in the United States, among whom disease severity varies considerably. One factor that influences disease severity is the sickle cell disease ...
The aim of this study was to evaluate the maternal and fetal complications in pregnant patients with sickle cell disease (SCD) and find risk factors of stillbirth.
Sickle cell disease (SCD), a congenital hemolytic anemia that exacts terrible global morbidity and mortality, is driven by polymerization of mutated sickle hemoglobin (HbS) in red blood cells (RBCs). ...
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...
