Introduction I. Attention Getter: A sickle is a blade used by farmers to cut down grains and crops. It does a great job because of its crescent moon shape. Unfortunately, a crescent moon is the worst possible shape for your blood cells, because they can 't do their job unless they 're round. According to cdc.gov, “Sickle cell disease is the most common genetic disorder in the United States and About 100,000 Americans are thought to be living with sickle cell disease, and every year another 1,000 babies are born with the disease.” II. Topic: The purpose of the topic sickle cell is to inform some of the many issues that come with being a sickle cell carrier whether its mild or severe. III.

2. Symptoms and Complications- Sickled red blood cells typically survive for only 10 to 20 days, a far shorter life span than the 120 days of normal red cells. The resulting deficiency of red blood cells may develop into severe anemia, which can produce fatigue and shortness of breath, as well as impeding growth and development processes and delaying sexual maturity. In addition, sickled cells are relatively rigid and cannot pass through narrow blood vessels as readily as normal red cells. They may block small blood vessels, impairing circulation and causing pain. B. According to Centers for Disease Control and Prevention “Sickle cell Trait is people who inherit one sickle cell gene and one normal gene have sickle cell trait (SCT). People with SCT usually do not have any of the symptoms of sickle cell disease (SCD), but they can pass the trait on to their children.” (sickle cell trait) 1. How sickle cell trait is inherited- if both parents have it there is a 50% chance that any child of theirs could be born with it. 2. Diagnosis/ complications- SCT is diagnosed with a simple blood test. People at risk of having SCT can talk with a doctor or health clinic about getting this test. Transition: Now that you have an idea of the difference between sickle cell
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
Sickle Cell Anemia is an inherited form of anemia, a condition in which there isn’t enough healthy red blood cells to carry sufficient oxygen throughout your body. Normally a person has flexible and round blood cells. With Sickle Cell anemia, Hemoglobin molecules in red blood cells, that carry oxygen in the body, are defective causing some of the red blood cells to change and form a sickle, or crescent moon shape.
In order to get Sickle Cell Anemia, you must have the Sickle Cell Trait. This is defined as "A person who carries one sickle hemoglobin producing gene inherited from their parents and one normal hemoglobin gene." (3) People who only have one copy of the mutation have the trait. "It is estimated that 1 in 12 African Americans has sickle cell trait." (3) Having the trait will NOT cause SCD. However, having the gene does allow you to pass the mutation on to your children. In fact, "A child conceived by two people with sickle cell trait has one chance in two of also having sickle cell trait, one chance in four of having sickle cell anemia."(3)
The shape of a sickle cell is basically a crescent moon or a "sickle" shape, hence the name. The sickle cells can get stuck in small arteries and veins because of their infamous shape and inability to squeeze through small areas, something regular red blood cells can do. The cause for this mutation is in the hemoglobin, a protein inside the red blood cell, which is what holds the oxygen being transported throughout the body (NIH, 2015). There is currently no cure for the sickle cell disease and it is also genetic.
Sickle cell is a blood disease. People with sickle cell anemia have crescent moon shaped blood cells that are hard and sticky. When the Sickle cells move through blood tubes, they can clog blood flow and break apart. This can cause main, damage, and a low blood count. The symptoms of the disease are not life threatening, however are not enjoyable. Sickle cell anemia can cause you to experience dizziness, headaches, and shortness of breath. Your skin may also turn more yellow or pale than it usually is. Sickle cell is an inherited disease. It is an unpreventable disease that you are born with. If you have a sickle cell gene, you do not have sickle cell, however your children have a 25% chance of having sickle cell anemia. This blood disorder can cause pain and discomfort but it is unlikely that your life will be in danger if you have the disease.
Sickle cell anemia (SCA) is an inherited blood disease which causes normal, round, healthy red blood cells to transform into sickle-shaped cells. Normal red blood cells are flexible and can easily pass through capillaries to bring oxygen to different parts of the body. However, sickle cells are fragile, and can easily die, leading to anemia (red blood cell deficiency). SCA can also cause blood vessel occlusion (blockage of blood vessels), tissue infarctions (death due to lack of oxygen), bone, joint, and abdominal pain, yellow eyes and skin, pale skin, delayed growth, increased risk of infections, and damage to organs. The disease is passed on by autosomal recessive inheritance, which means both parents of a child must have the defective gene for the child to be affected. If only one gene is inherited, the victim becomes a carrier of the sickle cell trait, producing only some sickle cells with little or no symptoms. This means two people with the trait have a 25% chance of having a baby with sickle cell disease, 25% chance of them having no defects, and 50% chance of the baby becoming a carrier as well. When the gene is inherited, it mutates the beta (β) globin gene in chromosome 11, changing the hemoglobins produced using instructions from the gene from a healthy hemoglobin A (Hb A) to a mutated hemoglobin S (Hb S). Many tests can be done to check for sickle cell disease, the most common being an ordinary blood test, where the blood is examined for hemoglobin S. If the
The term sickle refers to the fact that the red blood cells take on a sickle cell shape, instead of their normal biconcave shape (1). The cells can switch between the sickle shape and their normal biconcave shape (2). Sickled cells lose their pliability making it hard for the red blood cells to move through the smaller blood vessels (1). In their abnormal state they become more likely to adhere to the endothelium of the smaller vessels, causing clots to form and the possibility of stroke (2).
The disorders for Sickle Cell Anemia is mutation, autosomal recessive, and blood loss. The chromosomes traveled from one parent to another which mean it's a positive chance the child will have that disease. Also that
The cause of sickle cell anemia is by a mutation gene. The gene tells your body to make hemoglobin. Hemoglobin is responsible for giving the blood its red color and allows the red blood cells to carry oxygen from your lungs to all the parts of your body. The sickle cell gene is passed down from one generation to the next and is inherited. It is called autosomal recessive inheritance. This happens when both the mother and father pass on the detective form of gene. If only one parent passes on the sickle cell gene to the child that means the child will have the sickle cell trait. People who have the sickle cell trait are carriers and can pass the defective gene to their children. Your ethnic background can put you at risk for sickle cell anemia.
The condition creates when Sickle-molded red platelets hinder move through minor vessels to the midsection, mid-region, joints, and once in a while bones, bringing on great torment and distress. Torment may change in force and can keep going for a couple of hours to a couple of weeks. Some individuals encounter just a couple of scenes of torment. Others encounter twelve or more emergencies a year. In the event that an emergency is serious enough, it may oblige hospitalization. A significant muddling of Sickle cell frailty is oxygen hardship in blood and organs.
The sickle cell disease affects about 100,000 people in the America. The most common ethnic group the sickle cell anemia is seen in is African Americans and Hispanics. Approximately one in every ten African American and one in every one hundred Hispanic Americans have the sickle cell trait. Approximately two million people have the sickle cell trait in America. Approximately one in five- hundred African Americans and one in one thousand to one thousand and four hundred Hispanic-Americans have sickle cell disease. No universal cure has been found for sickle cell anemia (“Facts About Sickle Cell Trait And Disease,”n.d.). Sickle cell anemia affects many Americans and a universal cure needs to be found.
This disease can cause severe pain and fevers, anemia, circulatory problems, strokes, and even “sudden death.” The sickle cells are able to get caught in the capillaries and disturbs the circulatory system (Eckman 447). When a person has abnormal swelling in their feet and hands, this could be caused by a buildup of “sickle-shaped red blood cells blocking blood flow to the feet and hands.” When sickle cells damage an organ, this can make a patient more “vulnerable” to infections (Mayo Clinic Staff). For example, when red blood cells “get stuck in the spleen,” this causes a splenic sequestration crisis. When this occurs, most of the blood cells are sent to the spleen which leads to less red blood cells being able to circulate in the blood stream. Symptoms of a splenic sequestration crisis include, “shortness of breath” and “having pale
Sickle Cell Disease (SCD) is an inherited autosomal recessive condition that causes the red blood cells (RBCs) to be crescent shaped. Sickle cell disease occurs in 1 out of every 400 African Americans births (Field, et al 2009). And according to the Centers of Disease Prevention and Control (CDC), 1 out of 13 African American babies are born with the sickle cell trait (SCT). At the same time SCD is present in only 1 out of 300 Caucasian babies, thus it is considered to be one of the most prevalent genetic health disparities affecting people of African, Indian, Hispanic, and Mediterranean decent (Kotch, et al 2000).
According to National Heart, Lung, and Blood Institute (NIH), About 1 in 13 African American babies is born with sickle cell trait. About 1 in every 365 black children is born with sickle cell disease. There are also many people with this disease who come from Hispanic, southern European, Middle Eastern, or Asian Indian backgrounds. Approximately 100,000 Americans have SCD. Sickle cell is a disease that is genetic but, does not have to affect every member in the family. Persons with sickle cell trait (SCT) are heterozygous carries of an abnormal B-globin gene that results in the production of an abnormal hemoglobin, Hb S, which can distort red blood cells (Ojodu, Hulihan, Pope, & Grant,
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).
