Emerging Therapies For Sickle Cell Anemia

Sickle Cell Anemia is a disease that affects how oxygen is carried throughout the body by blood. Specifically, sickle cell anemia is characterized by a change in the shape of red blood cells from a smooth donut shape to a crescent or sickled shape. The sickled cells are very long and stiff, so many times

Sickle Cell Anemia is a very serious disorder and people suffer from it every day. It is a genetic disorder that causes the hemoglobin in the red blood cell to distort and form into a sickle like shape. The name comes from the shape of the blood cell after it is mutated. A person who has sickle cell anemia got it from inheriting from the parents. It is the most common inherited disorder in the United States. It is also has four other names this disorder can go by HbS, Hemoglobin S Disease, SCD, and Sickle Cell .(https://ghr.nlm.nih.gov)the blood cell is formed wrong turning it into a sickle or crescent shape. Sickle cell is only a disorder. It can also be treated a lot of different ways.

Sickle Cell Disease is an autosomal recessive genetic disease that occurs due to a mutation in the β-globin gene of hemoglobin. Autosomal meaning that it is not linked to a sex chromosome, so either parent can pass on the gene to their child. This mutation is a result of a single substitution of amino acids, Glutamic for Valine at position 6 of a β globin chain. The presence of this mutation causes

Sickle cell crisis is an acute form of sickle cell disease where pain and sickling are extensive (Byar, 2013). SCD is a genetic disease that predominantly affects black people of African decent (Gersten, 2016). Abnormal hemoglobin chains are the main issue with SCD (Byar, 2013). Normal hemoglobin chains are comprised of 99% hemoglobin A (HbA) however, in SCD an abnormal form of the gene, hemoglobin S (HbS) is present in approximately 40% of total hemoglobin (Byar, 2013). In order for a person to be born with SCD, both parents must carry the abnormal gene, HbS (Byar, 2013). HbS is extremely sensitive to the changes in oxygen amount of the RBC and when exposed to decreased oxygen the HbS cause the RBC to distort and become sickle-shaped,

It has always been assumed that genetics and lifestyle play a major role in the presence of health disparities and health care issue that affects African-Americans. This paper provides a historical background to a key disease more prevalent in the African American community, Sickle Cell Anemia, the history behind the disease, genetic mechanisms that influences once probability of inheritance and in-depth treatment on how to manage, prevent and sustain a healthy lifestyle when dealing with sickle cell anemia. Sickle cell anemia is a hereditary disease that alters important aspects of the body physiologically and can be inherited via genes. Sickle cell disease (SCD) was first identified in 1910 and has existed in the continent of Africa for five

In this article, sickle cell anemia is defined as a hereditary disease that destroys red blood cells by causing them take on an elongated and rigid "sickle" shape. In addition, a different type of hemoglobin called Hemoglobin S, is the protein in red blood cells that carry oxygen throughout the body. This protein starts to wrap around other red blood cells when oxygen is lacking to form a helical shape. Once this happens the cells cluster together and elongate and the cells start to "sickle". A person who has sickle cell anemia can only get it if both of their parents carry the sickle cell trait, if only one parent has the trait then there children are at risk for having the trait.

Sickle cell disease (SCD) occurs in 1 out of every 365 African American births compared to 1 out of 16,000 Hispanic-American births (1). SCD is a group of red blood cell disorders in which patients have a sickle or moon-shaped red blood cell due to an abnormal S hemoglobin. While sickle cell disease is relatively rare in American births, this is an alarming statistic among people of Sub-Saharan (west and central) African descent. An interesting fact is that SCD occurs more often among people from parts of the world where malaria is or was common, such as Sub-Saharan Africa (1). In addition, it is believed that people who carry the sickle cell trait are less likely to have

Sickle Cell Anemia has proven to be one of the most widespread genetic diseases in America, affecting 100,000 or more individuals according to the NHBLI (2008). Each person affected by sickle cell anemia must seek out expert advice and care for combating the disease, but as of late, care has been lacking in the medical field for these patients. Therefore providing optimal care and effective treatments for patients with sickle cell anemia will involve more research and funding in the future. Studies have shown that treatment for sickle cell patients is lacking and drugs are scarce and sparse, which has left this population medically neglected. The need to focus more research and allocate more funding toward sickle cell research is evident

Sickle Cell Disease or also widely known as Sickle Cell Anemia is a genetic mutation caused in red blood cells destroys its own cells within and reshaping the cell wall resembling crescent or sickle shape; getting its name of the sickle cell disease. These sickled shaped cells attempt to perform its normal function of circulating oxygenated and deoxygenated RBC and gets lodged in small vessels causing vaso-occlusion. Where vaso-occlusive take effect, rest of the body is not receiving oxygen becoming oxygen deprived results in acute and chronic pain and organ damage (Valerie Mann-Jiles, 2015). This disease a lifelong condition affecting not just the person carrying the disease but the whole family. Treating this disease

Sickle cell anaemia is a disorder affecting the red blood cells and up to 100,000 people are estimated to have the disease in the USA (Centre for Disease Control). Due to a genetic mutation in the gene responsible for the production of haemoglobin (MayoClinic, 2014) the red blood cells, which are usually a biconcave disk in shape, become sickle (bent) shaped (Figure 1) and the haemoglobin that the red blood cells contain is defective. Haemoglobin is a protein that carries oxygen (which has bind to the haemoglobin) around the body from the lungs after gas exchange. Having defective haemoglobin, as is the case with sickle cell anaemia, means

Sickle Cell Anaemia is a heredity disorder in which the red blood cells are affected by altering into a mutated-form of haemoglobin, most commonly at low oxygen levels. The altered-form of haemoglobin are crescent-shape; which are not flexible and can easily block the blood flow in smaller blood vessels and arteries (refer to figure 1). When both alleles inherited carry the sickle cell anaemia disease; 100% of the body’s haemoglobin will mutate into the sickle (crescent) shape. Sickle cell disease is the codominance of only one inherited sickled allele, in which; the carrier can pass the disorder but does not express any significant symptoms or the anaemia itself. Sickle cell anaemia is an autosomal recessive disorder, thus both alleles must

Sickle cell disease, SCD, is an inherited autosomal recessive genetic disorder that affects 1 in 500 Americans of West African descent with one in 12 African Americans and one in 100 Hispanics being carriers (“Learning.” 2014). SCD is prevalent in individuals with origins in equatorial countries, such as central Africa, Near East, Mediterranean area, and in parts of India (McCance, 2010). Sickle cell anemia, sickle cell-thalassemia, and sickle cell-Hb C are all forms of sickle cell disease with sickle cell anemia being the most severe. Within the general population there is a 0.7% chance of two African American parents having a child with sickle cell anemia, a 1 in 800 birth risk for sickle cell-Hb C, and 1 in 1700 birth risk for sickle- cell thalassemia (2010). The incidence of sickle cell trait carriers can range from 7% to 13% in blacks and up to 45% in people from Eastern Africa. In comparison to the other forms of SCD, sickle cell anemia is present in a homozygous form. Individuals are considered to be sickle cell trait carriers when they inherit Hb S from one parent and normal hemoglobin from the other parent, these individuals rarely present with any clinical manifestations (2010).

Sickle cell disease, also known as SCD, is a hereditary blood disorder that takes place due to mutation in the hemoglobin gene that is found in red blood cells. While it is said to have originated in Africa and is mostly predominant in African Americans, sickle cell disease is now common among different ethnic groups all over the world. Sickle cell anemia (HbSS) infects “an estimated 70,000 to 100,000 Americans”(Housman) and accounts for approximately 70% of anemia in the United States. Hemoglobin functions as an oxygen carrying protein as it carries oxygen from the lungs through the arteries and to the rest of the body. In sickle cell disease,

Sickle cell disease (SCD) is one of the many chronic health conditions yet to be well understood by health care professionals; hematologists included. It is an inherited genetic condition characterized by sickled shaped red blood cells, which alter their oxygen carring capacity. Sickle cell disease is passed from parents to offspring and it is characterized by numerous complications such as anemia, pain, infection, splenic crisis, acute chest syndrome, pulmonary hypertension, stroke, leg ulcers and multiple organ failure. It is an autosomal recessive disorder which means two copies of an abnormal sickle cell gene (Hemoglobin SS

Sickle Cell Anemia is a disease that affects how oxygen is carried throughout the body by blood. Specifically, sickle cell anemia is characterized by a change in the shape of red blood cells from a smooth donut shape to a crescent or sickled shape, almost the same shape as a crescent moon. The sickled cells are very long and stiff, so sometimes
