Sickle cell disease and malaria - PubMed Central (PMC).
Sickle cell anemia is a blood disorder common in Africa. Malaria is a blood-borne disease, also common in Africa. In recent decades researchers have observed correlations in their areas of effect.
Sickle cell disease is caused by a mutation in the hemoglobin of red blood cells. The most common, known sickle cell disease is sickle cell anemia. There is no cure for Sickle cell disease, but there was a treatment that help relieve pain, prevent infections, and prevent organ damage.
The relation between sickle cell and anemia gains further ground on the fact, that there is a greater incidence of sickle cell in the African lowland populations, where malaria is severe and widespread than among their highland counterparts. It is believed that sickle cell provides resistance against the malarial parasite.
People develop sickle-cell disease, a condition in which the red blood cells are abnormally shaped, if they inherit two faulty copies of the gene for the oxygen-carrying protein haemoglobin. The faulty gene persists because even carrying one copy of it confers some resistance to malaria.
The protective effect of sickle cell trait does not apply to people with sickle cell disease; in fact, they are more vulnerable to malaria, since the most common cause of painful crises in malarial countries is infection with malaria. People with sickle cell disease living in malarial countries should receive lifelong medication for prevention.
This is known as sickle cell disease crisis and may be brought on by anything from being caught in the rain to infectious diseases including urinary tract infection, diarrhoea, and malaria (Konotey-Ahulu, 1974, Olatundun, 2010, Sanjay et al., 2015).
Sickle cell disease is a common problem in Africa The gene for haemoglobin S (HbS), a structural variant of normal haemoglobin (HbA), is widely distributed in the developing world, having been selected to high frequencies by the protection afforded to carriers (HbAS; sickle cell trait) against malaria (1,2). HbS is the classic example of a.

Sickle cell disease is a genetic disease that most commonly affects people whose heritage is usually African or Caribbean. Patients with full blown sickle cell anemia have inherited a sickle gene from each parent and are usually diagnosed in childhood as having this autosomal recessive disease. Autosomal means that the gene is not located on either the X or Y sex chromosome.
Global map of the sickle cell gene confirms the 'malaria hypothesis' On a global scale, the sickle-cell gene is most commonly found in areas with historically high levels of malaria, adding geographical support to the hypothesis that, while potentially deadly, the gene avoids disappearing through natural selection by providing protection against malaria.
Sickle cell disease (SCD) is a group of inherited red blood cell disorders. If you have SCD, there is a problem with your hemoglobin. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. With SCD, the hemoglobin forms into stiff rods within the red blood cells. This changes the shape of the red blood cells.
Malaria is a mosquito-borne infectious disease that affects humans and other animals. Malaria causes symptoms that typically include fever, tiredness, vomiting, and headaches. In severe cases it can cause yellow skin, seizures, coma, or death. Symptoms usually begin ten to fifteen days after being bitten by an infected mosquito.
Sickle cell trait (HbAS) patients provide some resistance for malaria over normal persons (HbAA) or their homozygous state (HbSS) due to various reasons. Keywords: Falciparum malaria, Sickle cell trait, Sickle cell disease.
