Sickle cell anemia is an inherited disease in mostly people of Mediterranean, African, or Southeast Asian heritage which occurs when a person inherits the genes for sickle hemoglobin(NHLB). Sickle cell anemia is named from the shape that the red blood cells take because they become a crescent/sickle shape. Normally these red blood cells are flexible and round, but with sickle cell anemia they become rigid and sticky(Mayo Clinic) This shape inhibits the normal functions of red blood cells and they also cause blockages in blood flow to the limbs. The signs and symptoms of the disease vary, ranging from mild symptoms to drastic and hospital inducing health problems. There currently exists no widely available cure for sickle cell anemia, but as time passes and more research is done it is hopeful that there will be a cure.
1910 was the official discovery of the sickle cell disease(Howard). This was only the first discovery in America though, as the disease had been present in Africa for years before, and it had many names in the different tongues of the people there. The discovery in America was made by a Dr. James B. Herrick in a dental student studying in America who originated Grenada. Dr. Herrick analyzed the blood of the student under a microscope and saw red blood cells which he described as having the shape of a sickle and thus the name was born. Through the years as people were tested for this disease, doctors began to conclude that it originated and was nearly exclusive in people of African descent. in 1927, Dr. Hahn Gillespie found that by removing oxygen from people with the sickle cell disease. The sickling could also be found in others with relatives who had sickle cell. When deprived of oxygen, the ...

...eople. The physical and mental struggle effects more than two million people in the United States alone. This disease is one that does not get enough credit as a real risk to health. The people living with this hardship are faced with a bleak outlook until a cure is found, and until then there will be countless blood transfusions done and more and more clinical trials will need to be done to get everything in order to combat this disease. There are currently many trials under way in an attempt to test out new drugs for preventing the different symptoms of sickle cell(such as strokes in children) and to cure the disease as a whole. Before having children it is suggested that both parents get tested for the trait. A person can carry the trait but not be aware, and then pass it on to their child who may end up with more than just the trait, but get the disease itself.
Under hypoxic conditions, the abnormal hemoglobin start to change shape. They become sickled, stiff, and have greater difficulty moving though the blood vessels. As a result they begin to stick together and eventually block the tissues from receiving nutrients and oxygen. This causes the tissue to become infarcted and leads to pain. In a hypoxic states the cells are forced to make energy also known as adenosine triphosphate (ATP) without oxygen. This is called anaerobic glycolysis and results in the production of lactic acid as a byproduct (citation). The presence of lactic acid lowers the pH of the environment, the cells must recycle lactic acid back into the cells, and ATP production is significantly slowed. The cells
1. Sickle Cell Disease is life-threatening and has a risk of of causing depression. In this study I examine the experiences that Sickle Cell patients go through specifically at emergency healthcare facilities to find out if there are any negative stigmatizations surrounding this disease. There may be judgments that are made about these patients from healthcare professionals when they seek drugs for their pain relief that may cause the stigmatization to occur. I will also investigate why individuals that have Sickle Cell Disease experience longer waiting times at emergency healthcare facilities and the lack of control they may have over their care regime.
What is Sickle cell disease? Sickle cell affects a disease; that disease is called which affects the hemoglobin when the red blood cells that send oxygen through the body are killed off and weakened. Sickle cells can be found in every 1 and 1000 African Americans, it is affecting about 70,000 to 80,000 Americans in the United States. Sickle cell is a death threatening disease, and the severity of symptoms can vary from person to person (Sickle cell disease (SCD), 2015). Some people have light conditions, but others can have severe conditions, which, mean they could be hospitalized. Characteristics of this disease are caused by a minimum of low blood cells, which is called anemia.
The name of this patient is Davon; he is a five-year-old African-American male whom just moved from Chicago. The patient was visiting his pediatrician for a physical to enter kindergarten. The patient mother gave her history about confirming that she has the sickle cell trait and would like to know if her son is also a carrier for sickle cell. ("Sickle Cell Disease", 2015) “Sickle cell trait inherited from both hemoglobin A and S, in the red blood cells”. Those with this disease are still capable of having a healthy life. For instance, if one parent has sickle cell trait, and the other parent does not will only lead to the child having sickle cell trait or nothing. If both parents have the trait, then the child will genetically develop sickle cell disease inside the mother’s womb. Sickle cell trait is a transmitted disease that travels through the red blood cells. The symptoms of sickle cell trait is that when the skin gets pale, always cold, or even tired then that is a sign of having this disease. The patient cannot prevent this disease, due to this is something that is passed on from the womb and birth. Daily doses of penicillin can control the infection; on the other hand, it is not preventable. The only way to make sure that it does not get worse is the person must eat foods with high iron and even
During a short break of solitude from studying, I explored and came across that the environment in which most African Americans reside in has a high occurrence of malaria virus. The malaria virus disease is contagious and when it contaminates someone with sickle cell traits, it cannot survive on the external part of the human body so therefore the individual doesn’t develop the deadly malaria virus. While looking further into our class textbook on Human Genetics 11th Edition by Ricki Lewis, and this issue of sickle-cell among the African Americans, I
Sickle cell anemia occurs when a person inherits two abnormal genes (one from each parent) that cause their red blood cells to change shape. Instead of being flexible and round, these cells are more rigid and curved in the shape of the farm tool known as a sickle - that's where the disease gets its name. The shape is similar to a crescent moon.
The first funding for sickle cell disease began thirty years ago the federal legislation dealing with sickle cell was accepted. This legislation present notab...
As of 2013 an estimated study showed that over 100,000 people living with sickle cell anemia in the United States. One out of thirteen babies born to an African American parents will inherit the trait and one out of three hundred sixty five African American babies will be born with the disease. This is not just a black disease many Hispanics, Middle Eastern and individual with Asian background are also
Moreover, Mr. Johnson’s younger brother died in adolescence from the disease, after many painful and debilitating attacks. He thus knew it was a possibility that he himself was a carrier. Mr. Johnson also knew that the trait is fairly common among African Americans, about one in twelve is a carrier, so there was a good chance his fiancée was a carrier too. Ms. Sanford knows of no sickle cell disease in her immediate family, but she is in a racial group with a relatively high rate of
Sickle cell anemia is a disease that reforms the patient’s red blood cells, which makes the red blood cells has an abnormal shape like a sickle. Sickled red blood cells can result to severe anemia; decrease causes numerous painful symptoms in patients. A defective protein called hemoglobin is what cause the abnormal shape of the red blood cells in the sickle cell patients.
Sickle Cell is a disease that affects many people in the world today. It is the number one genetic disorder in the United States. Sickle Cell is deficient hemoglobin. Hemoglobin is what functions in providing oxygen to the cells in the body. The sickle shape comes from the atypical hemoglobin s molecules. Hemoglobin molecules are composed of two different parts called the alpha and beta. The beta subunit of the hemoglobin molecule has a mutation in gene, on chromosome 11 which produces the change in the red blood cell shape causing them to die and not reproduce accurately. The change in shape causes the red blood cells to get stuck in the blood vessels and block the effectiveness of oxygen transport causing pain and organ damage to the body. This disease does not have a cure and some common treatments are used to help patients live with the disease. Some treatment options are antibiotics (penicillin) to prevent infections, blood transfusions, folic acid that help produces new blood cells. These are just some of the current treatments for Sickle Cell.
The idea that there is a relationship between sickle-cell anemia and malaria was introduced by J. B. S. Haldane. Haldane was a british scientist who spent his life as geneticist, professor, biochemist, and writer. He was born November fifth, 1892 in Oxford, England. His father, John Scott Haldane, was a successful physiologist who did research on human respiration that affected the science world immensely. As a child, Haldane assisted his father in his research and experiments. He began this at the age of eight. Since he started so early, his knowledge was much more advanced than the average person by the time he finished his education. He completed his college education at more than one
Sickle Cell Disease is a condition where there is not enough healthy red blood cells to carry oxygen throughout the body. Another name for sickle cell disease is sickle cell anemia. Sickle cell anemia is inherited as a simple recessive condition. In normal red blood cells, the cells are usually flexible and round. However, in sickle cell disease the red cells become rigid and sticky. They are shaped like sickles or crescent moons. Because these cells are irregular, they can get stuck in small blood vessels. The small blood vessels slow or block blood flow. Without enough red blood cells in circulation a person's body cannot get the adequate amounts of oxygen needed to feel energized.
Sickle cell anemia is a genetically inherited and is a lifelong disease. Sickle cell anemia affects the red blood cells because it causes the cells to be crescent shape instead of how a normal cell looks like: an oval disk. This causes the circulation of the blood flow throughout the body to be clogged more often because people with sickle cell tend to have more blood clots. This also exhausts the body a lot more and people with this particular disease are more likely to get winded by a short physical activity. Sickle cell disease is caused by a mutation in the beta-globin gene. The main symptoms of sickle cell are shortness of breath, fatigue, difficulty breathing, deterioration of athletic performance, weakness, headaches, and dizziness. Another set of key features that
Sickle Cell Anemia is an inherited disease that targets the red blood cell. It is a lifelong disease and the severity of it varies from person to person. This disease turns regular healthy red blood cells into abnormal sickle shaped blood cells People with Sickle cell Anemia have hemoglobin in the red blood cells that is abnormal, which causes a person to have Hemoglobin S.
