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 ...
Sickle cell trait describes a condition in which a person has one abnormal allele of the hemoglobin beta gene (is heterozygous), but does not display the severe symptoms of sickle cell disease that occur in a person who has two copies of that allele (is homozygous). Those who are heterozygous for the sickle cell allele produce both normal and ...
It is used when the patient's hemoglobin is much lower than normal, for example an aplastic crisis. Exchange transfusion. Exchange transfusion involves removal of the patient’s blood and replacement with donor red blood cells. It is used to treat life-threatening complications of sickle cell disease such as stroke or acute chest crisis.
Broad spectrum antibiotics to cover common infections such as Streptococcus pneumoniae and mycoplasma, pain control, and blood transfusion. Acute chest syndrome is an indication for exchange transfusion. [citation needed] Bronchodilators may be useful but have not been well studied. [4]
Prematurely denatured sickle hemoglobin results in an upregulation of natural antibodies which control erythrocyte adhesion in both malaria and sickle cell disease. [25] Targeting the stimuli that lead to endothelial activation will constitute a promising therapeutic strategy to inhibit sickle red cell adhesion and vaso-occlusion. [26]
Specialty. Hematology. Hereditary spherocytosis (HS) is a congenital hemolytic disorder wherein a genetic mutation coding for a structural membrane protein phenotype causes the red blood cells to be sphere-shaped (spherocytosis), rather than the normal biconcave disk shape. This abnormal shape interferes with the cells' ability to flex during ...
Aplastic anemia causes a deficiency of all blood cell types: red blood cells, white blood cells, and platelets. [5][6] It occurs most frequently in people in their teens and twenties but is also common among the elderly. It can be caused by heredity, immune disease, or exposure to chemicals, drugs, or radiation.
Sepsis is a potentially life-threatening condition that arises when the body's response to infection causes injury to its own tissues and organs. [4][7] This initial stage of sepsis is followed by suppression of the immune system. [8] Common signs and symptoms include fever, increased heart rate, increased breathing rate, and confusion. [1]
