Correlation of low levels of nitrite and high levels of fetal hemoglobin in patients with sickle cell disease at baseline

Revista Brasileira de Hematologia e Hemoterapia, 2012
BACKGROUND: Sickle cell disease is a hemoglobinopathy characterized by hemolytic anemia, increased susceptibility to infections and recurrent vaso-occlusive crises that reduces the quality of life of sufferers.

Acetylation of Sickle Cell Hemoglobin by Aspirin [PDF]

Proceedings of the National Academy of Sciences, 1973
Incubation of HbS (or HbA) with aspirin leads to incorporation of acetyl groups into the protein. Incorporation was followed by the use of aspirin labeled with 14 C in the acetyl group. The acetylated hemoglobins show an increase in oxygen affinity compared to the parent proteins.

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Targeting transcription factors associated with hemoglobinopathies: Lessons from successful interventions and implications for cancer

Molecular Oncology, EarlyView.
This review summarizes the transcription factors, repressive chromatin‐modifying complexes, and epigenetic mechanisms that control fetal hemoglobin repression. Notably, many regulators of γ‐globin silencing also function in transcriptional and epigenetic networks that drive cancer, highlighting opportunities to translate advances in hemoglobinopathy ...

The Fabulous Impact of CRISPR Method in Sickle Cell Disease Treatment

Trends in Peptide and Protein Sciences, 2021
Sickle cell diseases are the most prevalent monogenic blood diseases with complications such as severe end-organ harm, pain, and reduced life expectancy. Dealing options for sickle cell diseases are inadequate, as there are just two FDA-approved drugs to

HOPE Kids 2: Phase 3, Randomized Trial of Voxelotor in Children With SCD and Conditional Cerebral Blood Flow Velocities

American Journal of Hematology, EarlyView.
ABSTRACT Children with SCD have elevated stroke risk, correlated with cerebral blood flow velocity (CBFV). HOPE Kids 2 was a phase 3, multicenter, double‐blind, placebo‐controlled trial evaluating the effect of voxelotor on CBFV. Participants aged 2 to < 15 years with SCD (HbSS/HbSβ0) and conditional CBFV (170 to < 200 cm/s) were randomized 1:1 to ...

The Presence and Percentage of Circulating Nucleated Red Blood Cells Reveal Distinct Characteristics in Adults With Sickle Cell Disease

American Journal of Hematology, EarlyView.
ABSTRACT Although circulating nucleated red blood cells (cNRBCs) have previously been detected in patients with sickle cell disease (SCD), their prevalence and clinical significance during steady‐state disease have not been established. We retrospectively analyzed 270 adults with an SS or Sβ0‐thalassemia genotype.

Unbinding of alpha chain of hemoglobin in sickle and normal structures

Journal of Physics Communications
Sickle cell disease, a genetic disorder, is caused by a mutation of glutamic acid into valine in β chain of hemoglobin at the sixth residue, resulting in structural change of the entire hemoglobin molecule into a sickle shape.

Neuroimaging Biomarkers in Paediatric Sickle Cell Disease [PDF]

, 2015
Sickle Cell Disease (SCD) is a collection of genetic haemoglobinopathies, the most common and severe being homozygous sickle cell anaemia. In the UK, it has been estimated that 1 in 2000 children are born with SCD. The disease is characterised by chronic
