Sickle cell disease ( SCD ), also simply called sickle cell, is a group of hemoglobin-related blood disorders typically inherited. [2] The most common type is known as sickle cell anemia. [2] It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2] This leads to a rigid, sickle -like shape under certain circumstances. [2] Problems in sickle cell ...
Sickle cell disease is a blood disorder wherein there is a single amino acid substitution in the hemoglobin protein of the red blood cells, which causes these cells to assume a sickle shape, especially when under low oxygen tension. Sickling and sickle cell disease also confer some resistance to malaria parasitization of red blood cells, so that individuals with sickle-cell trait ...
The Institute plans, conducts, fosters, and supports an integrated and coordinated program of basic research, clinical investigations and trials, observational studies, and demonstration and education projects. [3] Research is related to the causes, prevention, diagnosis, and treatment of heart, blood vessel, lung, and blood diseases, and sleep disorders. The NHLBI plans and directs research ...
A sickle cell health crisis can escalate into life-threatening complications, but patients still struggle to get seen quickly in emergency rooms and also to get pain medicine.
The FDA approved a new treatment for sickle cell disease. The therapy is first to use the ground-editing tool CRISPR.
Indications for red blood cell transfusion. Transfusion therapy for sickle-cell disease entails the use of red blood cell transfusions in the management of acute cases of sickle cell disease and as a prophylaxis to prevent complications by decreasing the number of red blood cells (RBC) that can sickle by adding normal red blood cells. [citation ...
Courtney D. Fitzhugh is an American hematologist-oncologist and scientist. She is a clinical researcher and head of the laboratory of early sickle cell mortality prevention at the National Heart, Lung, and Blood Institute .
Sickle cell nephropathy is a type of nephropathy associated with sickle cell disease which causes kidney complications as a result of sickling of red blood cells in the small blood vessels. The hypertonic and relatively hypoxic environment of the renal medulla, coupled with the slow blood flow in the vasa recta, favors sickling of red blood cells, with resultant local infarction ( papillary ...
Sickle cell-beta thalassemia is an inherited blood disorder. The disease may range in severity from being relatively benign and like sickle cell trait to being similar to sickle cell disease.
Acute chest syndrome. The acute chest syndrome is a vaso-occlusive crisis of the pulmonary vasculature commonly seen in people with sickle cell anemia. This condition commonly manifests with a new opacification of the lung (s) on a chest x-ray. [1]
