Severe Combined Immunodeficiency (SCID)
Severe combined immunodeficiency also known as SCID is a rare inherited immunodeficiency disorder which is caused by defects in one’s genes. SCID exposes life threatening infection through dangerous viruses, bacteria, and fungi to the human body which could possibly lead to death or permanent harm to one’s health. SCID is therefore known as the "boy in the bubble" syndrome because through the possibilities of exposure to different fatal infections, the immunodeficiency disorder has the ability to restrict one from direct contact with his or her environment, causing isolation to occur. Due to simple everyday environmental factors such as germs,

As of now, there are multiple types of ways in which SCID can be treated such as: Bone marrow transplant, Enzyme replacement therapy (mostly for ADA-SCID, which replaces enzymes which would help their immune systems to recover), and Gene therapy (discovered to be successful on April 3, 2002, on a boy with X-SCID by replacing the abnormal gene with a normal one). Ever since 1968, the bone marrow transplant has been the most common and best treatment for SCID; according to research, “A bone marrow transplant involves taking cells that are normally present in bone marrow (the center of bones that produce and store blood cells), and giving them back to the child with SCID or to another person”(Telsa). Through the bone marrow transplant, the old bone marrow is destroyed by high doses of chemotherapy, which is then replaced with new bone marrows. The bone marrow transplant is effective because it improves the child’s immune system because of the new healthy bone marrow cells in the system that is capable of protecting them from infections, causing the child’s body to fight infections better. Fred Hutchinson Cancer Research Center scientists were the first to begin with the development of the bone marrow transplant in order to different blood cancers. The development of the treatment was led by Dr. Donnall Thomas whose goal in his new discovery was to use radiation and chemotherapy to destroy the infected bone marrow, and replace it with a healthy bone marrow from a healthy patient in order to make cancer-free blood and immune system. The team of Dr. Thomas used this new technique on multiple patients and ended up having a 16-percent long time survival rate

    Boy in the Bubble

    When conducting the survey for whether David should have been removed from the bubble once doctors saw this his sister’s bone marrow was not a match for him, the winning answer was that no, David should not have been removed. To support this decision, the most important point to consider is that David’s life has been an essential study to develop the cure of SCID. By putting David in the bubble, doctors were able to learn more about SCID to help future generations. Whether you call this a “living experiment” or a “guinea pig”, there’s no doubt that researchers and doctors learned a great deal from David’s death to finally reach an experimental treatment in 1990. According to William Shearer, one of David’s doctors, "David's life was important, but his greatest contribution medically was his death, because with this information, we will be able to treat other children with this disease." After using David’s life as a resource for Doctors, a cure was developed through gene therapy in 1993. Keeping David in the bubble for as long as they could was the best thing the doctors could do for David, because had they let him out, they knew death was certain for him. Had they let him out, they would be euthanizing David against his wishes. David and his family always had the option to let him out of the bubble whenever they wanted. Because David’s life was essential to help future generations of SCID patients, David should not have been removed from the bubble once they saw his sister’s bone marrow was not a match for…

    In 1962, the criteria for the historical analysis of scientific developments was established; scientific development is not completely gradual and consecutive, but instead characterized by periods of steady progress that are interrupted by scientific revolutions of thought and changes in what was held to be fundamentally true (Kuhn). These significant changes are caused by a crisis that lead to solutions for pressing current problems; in this way the aids crisis acted as a catalyst, for it gave the scientific community the necessary push to investigate the nature of retroviruses. Before this point, significant process had been made; Ellermann and Bang (1908) isolated the first oncogenic retroviruses. Temin and Rubin (1958) were able to describe…

    In the last century, there have been a number of discoveries regarding the treatment of human disease and genetic conditions. The current on-going research is in the field of gene therapy, an experimental technique that uses genes to treat and replace the defective genes of an affected person. Instead of treating disease symptoms, this has the potential to correct the underlying cause (1). Besides its high costs and ethical concerns (therapy involving germ line treatment), this technique also poses a considerable amount of risk. Thus, gene therapy is currently only being tested on the diseases for which there is no cure. This article shall look primarily into cystic fibrosis, as well as X-linked severe combined immunodeficiency (SCID), as examples to describe the potential of gene therapy in medicine.…

    Sickle-Cell Anemia

    • 1625 Words
    • 7 Pages

    Sickle-cell disease is a genetic disorder that results from the abnormal structure of red blood cells. The peculiar shape of the red blood cell prevents the normal absorption of oxygen. This disease results from the abnormal production of hemoglobin S (HbS). Therefore, a mutation in this gene causes a lower supply of oxygen to the cells, which results in occlusion of the blood vessels. Individuals diagnosed with sickle-cell anemia have abnormal function of the gene that encodes for subunit B, which is a protein that serves as part of the hemoglobin A (HbA). The HbA is responsible for oxygen binding through the blood stream. Indeed, the abnormal polymerization of hemoglobin occurs in homozygous individuals with sickle-cell anemia, which lowers the oxygen supply of red blood cells. To lower the negative consequences of sickle-cell anemia, it is necessary to provide a better understanding of the genetic material that underlies the sub-phenotype of sickle-cell anemia. Therefore, this could help in the discovery of drugs that could target the genes responsible for sickle-cell anemia.…

    Two parents, Jenny and Bob Miller, are both well educated and rich. They have two children, James and Andrew, who are both stricken with muscular dystrophy. The prognosis is that their muscular systems will gradually deteriorate, resulting in an early death. Yet the advances of medicine hold out the promise of a possible cure in the foreseeable future with gene therapy. Closer to hand is the possibility that embryonic muscle cells from normal individuals might be injected into people suffering from muscular dystrophy, which could bring about partial relief for James and Andrew. There are risks, however, as with any experimental method, such as the possibility of immunological rejection of the foreign cells.…

    Stem cells are primitive cells found in embryos, fetuses, and recently adults that can grow into 210 types of cells in the body. James A. Thomson, an embryologist at the University of Wisconsin, and John D. Gearhart of the Johns Hopkins University School of Medicine announced on Thursday, November 8 1998 that they and their colleagues had isolated the cell. Scientists have tried for years to find stem cells because of their great medical value. Diseases such as Diabetes, Bone Marrow Cancer, Chronic Heart disease, Parkinson's, and Alzheimer's disease are just a few that could all be cured with the use of stem cells.…
