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.
Some of our population may be more at risk then others due to the ethnic background. This diseases is more prominent in some races more than others and studies have shown where the numbers increase or decrease depending on the race. Decedents of Africa, India, the Mediterranean, South and Central America and the Caribbean have a higher percentage of diagnoses. Countries who are exposed to the malaria parasite have the higher number of Sickle Cell cases. The percentage of African Americans with sickle cell is about 1 in 500 and a percentage 1 in 1,000 to 1,400 in Hispanic Americans. People of Caucasian race are less likely to have the diseases because of the history of the d...

...ronchoscopy is necessary to identify any type of infection in the body. Corticosteroids are used as a remedy for sickle cell patients; it is administered thru the vein and can help reduce the amount of time a patient spends in Stem Cell treatment is another option being looked at as an option for Sickle cell patients. A study conducted in UCLA by Dr. Donald Kohn where the hematopoietic blood from Bone marrow is used to treat Sickle cell Patients. The treatment was provided by introducing the non-sickle cell gene into the hematopoietic stem cell which will help produce healthy red blood cells versus the sickle cells. The blood used for this treatment comes from the actual person carrying the mutated gene and then its re introduced into the hematopoietic stem cell (bone marrow) with the possibility of renewing and multiplying healthy new red blood cells. hospital.
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.
Sickle cell disease is a group of disorders that affects the blood, specifically, a molecule called hemoglobin in red blood cells (“sickle cell disease”, 2016). Hemoglobin is a molecule that facilitates the delivery of oxygen throughout the body (“sickle cell disease”, 2016). A mutant form of the hemoglobin molecule causes red blood cells to become crescent shaped or “sickled shaped” (Lonergan et. al. 2001). This distorted shape of red blood cells causes rigidity of the blood cells and vaso-occulusion (or the blood vessels to become clogged) (Rees et.al., 2010). This often leads to a low number of red blood cells (anemia), repeated infections and episodes of pain that are periodic (“Sickle cell disease”, 2016). Although sickle cell disease
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.
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 an abnormal form of hemoglobin (HbS) is produced. HbS molecules tend to clump together, making red blood cells sticky, stiff, and more fragile, and causing them to form into a curved, sickle shape. Red blood cells containing HbS can go back and forth between being shaped normally and being sickle shaped until they eventually become sickle shaped permanently. Instead of moving through the bloodstream easily, these sickle cells can clog blood vessels and deprive the body's tissues and organs of the oxygen they need to stay healthy.
According to the Centers for Disease Control and Prevention (CDC), sickle cell disease (SCD) affects millions of people worldwide and predominantly affects descendants from sub-Saharan Africa, South and Central America, the Caribbean, Saudi Arabia, India; and the Mediterranean. Sickle cell disease is a genetic disorder of the red blood cells where the red blood cells comprises of predominantly hemoglobin S, an abnormal type of hemoglobin (2011). Two most common types of sickle cell disease seen in the clinical setting are Sickle Cell Anemia (SS) and Sickle-Hemoglobin C Disease (SC) (Sickle Cell Disease Association of America, 2014, para.1).
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.
Most villagers that are dying from sickle-cell anemia will come from the villagers at the very wet regions where there are many mosquitoes. The simulation shows that the malaria death for very wet regions rate is 0.2, that is the highest number compared to other regions. It is because there are many mosquitos in that area, so that area might be where malaria has long been endemic. Because of that, the villagers in those very wet regions have evolved dozens of chemical as defenses against malaria and the sickle cell is one of them (anti-malarial). Natural selection acts so that people with sickle cell allele are more common in those very wet regions as they survive and reproduce better in the environment where malaria is endemic, especially those people with heterozygous sickle cell allele (HbA/HbS) as it acts as ‘shield’ that protect them from dying from malarial disease and also sickle cell disease. However, those who have sickle cell allele especially the homozygous for the
Sickle Cell Disease (SCD) is an inherited red blood cell disorder that can clog blood flow. The symptoms for the SCD vary from mild to severe depending on which type of sickle cell disease a person has. Most infants will not show symptoms until they are 5-6 months of age. Some of the early symptoms that a child can get are painful swelling of hands or feet, fatigue, jaundice or icteris. Infants before eight weeks old are to have their first SCD screening. It is best do it that early because complications can be prevented with an early diagnosis and treatment. A more common and severe sickle cell disease that a child can inherit from a parent is called the hemoglobin SS disease, also know as sickle cell anemia. People with this disease do not
Like many disorders, sickle cell disease is inherited. A person who has the disorder must inherit the two genes for sickle hemoglobin from one’s parents. Many people could be carriers for the disease,possess no symptoms, and later pass it on to their own children. Furthermore, when you were conceived, you received a set of genes from your dad(sperm) and another set from your mom(egg). Inside structures, called chromosomes, where DNA is tightly coiled, there contained are
Sickle Cell Disease is inherited from parent to offspring. In the last counseling session, I mentioned that the disease is caused by the mutation in chromosome 11. This mutation does not occur randomly. The mutation first occurred thousands of years ago, and ever since then, the select few offsprings of the person that first received the mutation have inherited the mutated gene (controls inherited traits).
The purpose of this essay is to tell how has malaria affected people that have sickle cell and is sickle cell common in places malaria is common, and how it correlates with each other? Malaria and sickle cell allele have a direct correlation on how many countries have malaria versus people with the HbS allele because, HbS allele is affected by the presence and absence of malaria, the effect malaria has on people with the HbS allele, and technological advancements.
Sickle-cell disease is a blood disorder genetically caused by a point mutation in the β-globin trait . A point mutation defined by “Principles of Life” is “a result from a gain, loss, or substitution of a single nucleotide.” This single change to the gene codes for a polypeptide and not the normally needed protein. Instead of coding for a glutamic acid, it codes for a valine.
100 Hispanic-Americans has sickle cell trait,1 in 1000-1400 have the disease..100,000 people have sickle cell disease, and 2 million people have the trait in USA.
Hemoglobin A, an oxygen-carrying protein in blood cells, becomes abnormal once a point mutation occurs on chromosome 11. The mutation causes the sixth amino acid of the protein to change from glutamine to valine, resulting in the abnormal hemoglobin S. An autosomal disease known as sickle cell anemia is caused by having homozygous recessive alleles of hemoglobin S. Hemoglobin S form stiff strands within the blood cell which results in the sickle, or crescent shape of the diseased blood cells. Unlike healthy blood cells, the sickle cells are not flexible and often stick to vessel walls, causing painful blood clotting or a vaso-occlusive crisis. Patients can also suffer from joint pain, hematuria, jaundice, and dizziness. The life expectancy of sickle cell patients in North America, the Caribbean, and Europe is mid 40’s. However, approximately 240,000 of the 300,000 people born annually with sickle cell anemia are born in Sub-Saharan Africa and around 50% to 80% of those sickle cell anemia patients die before the age of five. The great discrepancy in life expectancy can be pointed to the poor healthcare infrastructure in the majority of Sub-Saharan African
