Sickle Cell Anemia is an inherited blood disorder that is extremely challenging to live with. Its symptoms are many, with the most prominent being severe pain that can become unbearable to the point where hospitalization is required. Because sickle cell is a genetic disorder, a person is born with it and it is usually permanent. Unfortunately, there are risks and complications associated with this disease. However there are various treatment options for a patient with sickle cell and also support to help people understand and cope with this challenging disease.
Background
A patient with sickle cell has inherited the condition from both parents, and it all starts in the hemoglobin. Hemoglobin is “an iron-containing protein in red blood cells that reversibly binds to oxygen” (Reece, Urry, Cain, Wasserman, Minorsky, & Jackson, 2011). Obviously, hemoglobin is an important substance for oxygen to be transported in red blood cells. However, a patient with sickle cell has irregular hemoglobin cause by inherited genes. This “oxygen delivery” system cannot function properly because a gene
Sickle Cell Anemia has mutated. This mutation results in distorted, “sickle-shaped” cells, which often get trapped in the blood vessels of the body. Because of this, a sickle cell patient can have severe oxygen deprivation resulting in extreme pain. Oxygen is necessary to survive and thrive, but when a person doesn’t receive enough oxygen to any part of the body, the consequences are excruciating.
Although symptoms are not immediate, and usually arise after a child is four months of age, this disease is onset before birth, meaning that you are born with it. Like any disease or disorder, early diagnosis is important. Antibiotics and immunizations are...

Conclusion
Sickle Cell Anemia seems to be one of the hardest conditions to live with due to the severity of its symptoms and it can be an encumbrance to everyday life. Although this condition is hard to live with, it is possible to live with it. Thanks to the twenty-first century advancements, there is great medical care available to patients and many other resources and support groups to help families through this harsh reality of living with sickle cell. Perhaps one day there will be a readily available cure for this horrible disease. Until then, a patient with sickle cell should have a support system and take care to live a healthy life so that they can live their life to the fullest.

How is it diagnosed? • Usually before birth, around the second trimester, doctors can diagnose Sirenomelia through ultrasound or sonogram • Immediately after being born, doctors can tell if the baby has Sirenomelia through physical observation What are the possible complications? The severity of Sirenomelia varies among individuals. Many babies die during birth and those living can face long-term effects including: • Renal problems such as kidney failure or absence of either one or both kidneys • Cardiovascular problems such as Heart problems • Pulmonary problems include immature, small or abnormal lungs structures • Absent of bladder, large and small intestines and other organs • Abnormalities in upper extremity such as the brain, arms or spine • Inability to walk or move normally without the help of others • Present of urethral agenesis • Possible growth delay in the brain, arms or spine • Symptom How is it Treated?
When the children are diagnosed they have a number of symptoms that point towards progeria. When they are born there is no sign that they have progeria. They look like normal babies. They start having the appearance of someone with progeria as they get into their first or second birthday. They start to loose all of their hair, including the eyebrows, their veins start sticking out like an elderly person's would. They have ears that have no ear lobes and that stick out a lot."A broad, mildly concave nasal ridge nose, prominent eyes, thin lips and micrognathia (small jaw) with a vertical midline groove in the chin."(Baek, McKenna, Eriksson, 2013) Their teeth grow slowly...
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

Due to the blockage of blood flow in the arteries sickle cell anemia causes many complications. The trademark of sickle cell anemia is a sickle cell crisis, which causes sudden serve pain. A common problem is acute chest syndrome, which is triggered by an infection or by blockage of blood vessels in the lungs. Which if left untreated, can be cause organ damage or even death.
Sickle cell anemia is the most common in hemoglobin mutation diseases due to mutation to beta-blobin gene. The substitution of valine for glutamate at position 6 of the beta chains paces a nonpolar residue on the outside of hemoglobin S. the oxygen affinity and allosteric properties of hemoglubin are virtually unaffected by this changes. However, this alternation markedly reduces the solubility of the deoxygenated but not the oxygenated form of hemoglobin. Thus, sicking occurs when there is a high concentration of the deoxygenated form of hemoglobin.
Sickle Cell Anemia is a disease found right here in America, but in low levels compared to some areas of the world. The rate for this disease is around five times greater in certain places in Africa. That is because the potentially fatal disease Sickle Cell Anemia can also work as a sort of vaccination for another disease called malaria. First the mechanics of Sickle Cell Anemia will be discussed, then its possible benefits.
Individuals who inherited this disease from their parents do not possess the standard hemoglobin that should be contained in RBC. Hemoglobin is a protein present in RBC, which transports oxygen to all parts of the body (National Heart and Blood Institute, 2017). The disease which impairs the hemoglobin’s responsibility, prevents blood cells from receiving the sufficient oxygen, causes RBC to be sickle shaped. Sickle cell disease precedes to several painful health complications such as VOC (vaso- occlusive crises), which are severe pain recurring episodes, that can lead to irreversible organ damage. Sickle cell anemia causes red blood cells to hemolyze continuously through an individual’s lifetime… hemolysis is the breakdown of red blood cells (Krishnamoorthy, et al. 2017). An experimental study was conducted with SCD Townes mice to test a possible solution for sickle cell anemia. Throughout a seven-week span, mice orally conveyed dosages of 100 mg/kg of DMF. DMF known as dimethyl fumarate is small complex molecule and which binds and activates to enhance Nrf2 to enhance Hbf. “Nrf2 is a transcription factor that triggers cytoprotective and antioxidant pathways to limit oxidative damage, inflammation, and increases HbF” (Krishnamoorthy, et al. 2017). Fetal hemoglobin (Hbf) is the hemoglobin present in fetuses; it is responsible for the transportation of oxygen
Do individuals X, Y, Z have Sickle Cell Anemia or Sickle Cell trait? In this investigation three DNA samples were tested to see if they had Sickle Cell or carry the Sickle Cell trait. Sickle cell Anemia is a disease of the red blood cells that is inherited from your parents. Sickle Cell is caused by point mutation in which a single base in the ꞵ-globin gene that results in the substitution of valine instead of glutamate in the amino acid chain. The acid change aggravates the blood cells and make them take a sickle shape and lose elasticity. The main purpose of Hemoglobin is to carry oxygen from the lungs to the body’s tissues. To carry out this function a healthy red blood cell has a hollowed circular cavity which allows them to hold nutrients
In America alone there are 100,000 cases of people who have inherited the sickle cell disease and there are 2 million people who have inherited the Sickle cell trait. Sickle cell disease, or as it is more commonly referred to, Sickle cell anemia has been present in the world for over five thousand years. Originating in Africa it spread throughout the world. Sickle Cell Anemia can affect all people no matter what age or gender, has symptoms and causes, an outlook, and people who are surging through this disease to live their lives.
