Both may present with a new opacification of the lung on chest x-ray. The presence of fevers, low oxygen levels in the blood, increased respiratory rate, chest pain, and cough are also common in acute chest syndrome. Diagnostic workup includes chest x-ray, complete cell count, reticulocyte count, ECG, and blood and sputum cultures.
The American Society of Hematology (ASH) is a professional organization representing hematologists, founded in 1958. Its annual meeting is held in December of every year and has attracted more than 30,000 attendees. [ 1 ]
Victoria Gray was the first patient ever to be treated with the gene-editing tool CRISPR for sickle-cell disease. [1]This marked the initial indication that a cure is attainable for individuals born with sickle-cell disease and another severe blood disorder, beta-thalassemia.
Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders that are typically inherited. [2] The most common type is known as sickle cell anemia. [2] Sickle cell anemia results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2]
The Sickle Cell Disease Association of America, Inc. (SCDAA) is a nonprofit organization with the sole purpose of supporting research, education and funding of individuals, families those who are impacted by sickle cell disease.
The American Society of Hematology recommends that people with sickle cell disease have their blood typed for the RhC/c, RhE/e, Kell, Duffy, Kidd, and MNS antigens prior to transfusion, [12]: 130–1 because they often require transfusions and may become sensitized to these antigens if transfused with mismatched blood.

A sickle allele is always the same mutation of the beta-globin gene (glutamic acid to valine at amino acid six). In contrast, beta-thalassemia alleles can be created by many different mutations including both deletion and non-deletion forms.
The sickle cell trait provides a survival advantage against malaria fatality over people with normal hemoglobin in regions where malaria is endemic. The trait is known to cause significantly fewer deaths due to malaria, especially when Plasmodium falciparum is the causative organism.
