Question 1

is malaria and sickle cell anemia related?

Accepted Answer

No: Malaria is an infectious disease transmitted by mosquitoes. Sickle cell is a genetic disorder resulting in a disruption in the oxygen carrying capacity of red blood cells. 

Sickle cell is a disorder observed in african americans.

Question 2

how did sickle cell anemia relate to malaria?

Accepted Answer

Resistance: Red blood cells whose structure is altered by sickle cell trait or disease are more resistant to invasion by plasmodium spp., the organism which causes malaria.

Question 3

what causes sickle cell anemia besides malaria?

Accepted Answer

Malaria doesnt cause: Sickle cell anemia is a hereditary disease caused by a mutation in the dna coding for hemoglobin.  Scientists have long known that sickle cell anemia protects carriers from malaria infections, which could be advantageous in certain parts of the world.  Malaria does not cause sickle cell anemia.

Question 4

how is it that sickle cell anemia formed because of malaria?

Accepted Answer

I think: You are asking what is the relationship between sickle cell anemia and malaria. People with sickle cell trait are somewhat protected against certain infections with malaria. This survival advantage allows for the propagation of the sickle cell gene to the offspring, and if the offspring have a survival advantage over those without the gene, they will have the opportunity to continue propagate.

Question 5

i'm wondering why are carriers for sickle cell anemia resistant to malaria?

Accepted Answer

Sickle and malaria: Patients with sickle cell disease are protected against  severe and complicated malaria infection- by 2 mechanism: -1.  Cells infected with malaria parasites had accelerated sickling compared with non-infected cells- and as the result the cell would be destroyed/ promoting removal of infected cells from the circulation
`2.Impaired parasite growth due to reduce o2 content in sickle cell.

Question 6

why is it that carriers of sickle cell anemia are immune to malaria?

Accepted Answer

Malaria infects RBCs: Malaria infects red blood cells.  Persons with sickle cell trait will often be "immune" because the malaria infection is not allowed to propagate through the rbcs because the sickle trait causes them to die a little faster when infected.  Persons with sickle cell disease get very sick with malaria, because of sickle cell related complications.  Persons with normal hemoglobin gets sick from malaria.

Question 7

is sickle cell anemia prevalent where malaria doesn't exist?

Accepted Answer

Only here in the US: If you compare a MAP of malaria prevalence (number of cases) to a MAP of sickle cell disease prevalence, they are almost super-imposable with one exception; the United States. The prevalence of sickle cell anemia in the us is as high as some african countries with lower malaria frequencies, but our only malaria comes from travelers.

Question 8

why are people who are heterozygous for sickle cell anemia more resistant to malaria?

Accepted Answer

Malaria: In a person who has sickle-cell trait – the red blood cells are destroyed prematurely before the Plamodium can reproduce.  Sickle Cell Trait can provide a protective advantage against P. Falciparum. According to one study “Sickle cell trait provides 60% protection against overall mortality. Most of this protection occurs between 2-16 months of life, before the onset of clinical immunity in areas &gt;

Question 9

how are sickle cell anemia and malaria related? i've heard of an evolutionary advantage.

Accepted Answer

Sickle and malaria: Patients with sickle cell disease are protected againts severe and complicated malaria infection- by 2 mechanism: -1.  Cells infected with malaria paracytes had accelerated sickling compared with noninfected cells- and as the result the cell would be destroyed/ promoting removal of infected cells from the circulation
`2.Impaired paracyte growth due to reduce o2 content in sickle cell.

Question 10

can you please tell me why it'sthat only carriers of sickle cell anemia are immune to malaria?

Accepted Answer

Both carriers and : People with the disease are protected (not immune). People with trait historically were more likely to survive into adulthood to pass along the sickle cell gene. People with ss hemglobin, until recently, were not likely to survive into adulthood to have children.
