Genetic disorders beta thalassemia essay

Oral deferasirox and deferiprone were consumed by 3 8. NTDT is diagnosed when patients fulfilled at least two of the following criteria If Thalassemia A is detected in utero, a technique which allows in utero blood transfusions to be performed may save the life of the unborn baby.

With the majors B type for example, at birth children appear to be normal, but after six months they develop severe anemia due to the hemoglobin switches from F to A. If the results are less than thirteen, Thalassemia is more likely.

The hypercoagulable state in patients with NTDT has been primarily attributed to abnormalities in platelets and the pathological red blood cells, although several other factors are believed to be involved leading to clinical thrombosis.

These children will have growth failure, bone deformities, hepatosplendomegaly enlargement of the liver and spleen and are jaundice. Because blood transfusions can lead to iron overload, patients will need to be tested.

Splenectomized patients have a substantially higher number of these negatively charged pathological red blood cells and in turn show higher thrombin generation Individuals suffering from the major form, tend to need frequent blood transfusions in order to survive.

It has been demonstrated that NTDT patients have 4 Genetic disorders beta thalassemia essay 10 times higher prostacyclin and thromboxane A2 metabolites, both markers of hemostatic activity, as compared to healthy individuals The gene for alpha globin is located at chromosome 16 and the gene for beta globin is located at chromosome Elevated white blood cells are known risk factors for thrombosis in sickle cell anemia.

It is a genetic disorder that is recessive; therefore both parents must be carriers to pass on the disorder in its major form. Growth differentiation factor 15 inhibits hepcidin expression by opposing the effect of BMP, thereby leading to increased intestinal iron absorption and increased iron release from macrophages A hemoglobin electrophoresis with a finding of elevated Hgb A2 and F is noted.

But overall NTDT patients are iron overloaded despite being transfusion independent due to chronic anemia leading to increased iron absorption from gut and increase release of iron from phagocytes due to low levels of serum hepcidin.

Both will e increased in Beta Thalassemia trait without iron deficiency and will be normal or decreased in Alpha thalassemia. Further worsening of the situation occurs when the enzymes and peptides released by activated white blood cells cause blood vessel damage to cause arteriopathy lesions.

Some of these factors are: Diagnosed patient of non-transfusion dependent thalassemia. Hemoglobin contains proteins called globins. This index divides the red blood cell count and puts them into a mean.

Manfre et al gave the first documentation of silent stroke in NTDT patients in They at the same time release cytokines which recruits other activated platelets and RBC.

Contraindications to undergo MRI examination. This combination will cause an intermediate form of hemolytic anemia. Those who are chronically transfused need aggressive monitoring to maintain their well-being. When an MCV indicates numbers greater than eighty, the individual does not carry trait.

In the years to come, I understood that the only way I could make sure I had happy healthy children, was to dive into genetic counseling with whoever was to become my husband. This reiterates the fact that chronic anemia predisposes the patient to develop silent stroke.

Prior toiron overload was the main reason most children with major thalassemia died in their late teens to early twenties. Researchers are looking toward gene therapy as a possible curative approach. In NTDT, the genetic basis for phenotypic diversity is best explained in terms of primary, secondary, and tertiary genetic modifiers9.

Measuring iron overload in the liver is done with the R2 Technique and assessing cardiac damage from iron overload is done with the T2 Technique.

Gene therapy and fetal hemoglobin is a technique done, where the scientist insert a normal fetal gene into the stem cell of the unborn child having thalassemia.
