OBJECTIVE To improve prediction of sickle cell anemia severity at an early age, we evaluated whether absolute reticulocyte count (ARC) or hemoglobin (Hb) levels during early infancy (2-6 months of age) in patients with sickle cell anemia predict the risk of later developing an abnormal (abTCD) or conditional (cdTCD) Transcranial Doppler (TCD). STUDY(More)
Several associations have been described between the frequency of human leukocyte antigen (HLA) class I genes in certain populations and the risk of developing nasopharyngeal carcinoma (NPC). Associations between ethnic background and geographic distribution, and relative disease incidence have been reported. Populations in geographical areas at higher risk(More)
Patients with sickle cell disease (SCD) are occasionally prescribed systemic corticosteroids to treat steroid-responsive conditions. Additionally, use of systemic corticosteroids for sickle cell pain episodes and acute chest syndrome is under investigation. We report 4 patients with SCD who developed severe vaso-occlusive events following the administration(More)
Thrombotic complications in pediatrics are more common today due to our ability to treat complicated diseases. In pediatric patients where thrombolytic therapy is indicated, the lack of evidence-based medicine forces practitioners to extrapolate dose recommendations for recombinant tissue plasminogen activator (rt-PA) from adult studies. This often results(More)
The need for fast, efficient, and less costly means to screen genetic variants associated with disease predisposition led us to develop an oligo-nucleotide array-based process for gene-specific single nucleotide polymorphism (SNP) genotyping. This cost-effective, high-throughput strategy has high sensitivity and the same degree of accuracy as direct(More)
Sickle cell disease (SCD) patients are at increased risk of red blood cell (RBC) alloimmunization. Recipient inflammatory state at time of transfusion has been shown to regulate alloimmunization in murine models, but evidence is lacking in SCD patients. We retrospectively studied a cohort of alloimmunized SCD patients to determine the influence of(More)
Blood component transfusion is integral in the treatment of infants and children by pediatricians, surgeons, intensivists, and hematologists/oncologists. Technologic advances in blood collection, separation, anticoagulation, and preservation have resulted in component preparation of red blood cells, platelets, white blood cells, and plasma, which are(More)
African individuals harbor molecular RH variants, which permit alloantibody formation to high-prevalence Rh antigens after transfusions. Genotyping identifies such RH variants, which are often missed by serologic blood group typing. Comprehensive molecular blood group analysis using 3 genotyping platforms, nucleotide sequencing, and serologic evaluation was(More)
Induction of fetal hemoglobin (HbF) has therapeutic importance for patients with sickle cell disease (SCD) and the beta-thalassemias. It was recently reported that increased expression of LIN28 proteins or decreased expression of its target let-7 miRNAs enhances HbF levels in cultured primary human erythroblasts from adult healthy donors. Here LIN28A(More)
BACKGROUND Intracranial aneurysms (IAs) are rare in the general pediatric population and account for <2% of all cerebral aneurysms. Only 7 children with sickle hemoglobinopathy and IAs have been reported, the majority of which were discovered after rupture. OBJECTIVE To report the prevalence of unruptured IAs in a selected population of children with(More)
