The hemoglobin that is present within the red blood cell is composed of a protein called globin. There is a substitution of an amino acid in this protein. As a result when the oxygen is given up by hemoglobin it changes its shape and becomes elongated thus changing the shape of the red blood cell into a sickle looking cell.

If you have sickle cell trait, you have inherited the gene for sickle cell disease. Sickle cell trait does not turn into sickle cell disease. If someone has sickle cell trait and his partner has sickle cell trait they may produce a child with sickle cell disease. There are about 2.5 million people in America with sickle cell trait.

Sickle cell disease is a global health problem. In the United States it is estimated that over 70,000 people have sickle cell disease. About 1,000 babies are born with the disease each year in America.

Sickle cell disease is an inherited disorder that affects red blood cells. People with sickle cell disease have red blood cells that become hard and pointed instead of soft and round. Sickle cells cause anemia, pain and many other problems.

Sickle cell anemia is an inherited blood disorder, characterized by chronic anemia and periodic episodes of pain. The underlying problem involves hemoglobin, a component of the red cells in the blood. The hemoglobin molecules in each red blood cell carry oxygen from the lungs to the body organs and tissues and bring back carbon dioxide to the lungs. The abnormal hemoglobin molecules tend to cluster together and from long, rod-like structures.

Babies are tested to see if they have sickle cell disease. Teens and adults are tested mainly to see if they can have a baby with the disease.

Lung tissue damage, pain episodes and stroke. The blockage of blood flow caused by sickled cells also causes damage to most organs including the spleen, kidneys and liver.

Sickle cell is a condition that affects the normal oxygen carrying capacity of red blood cells. The symptoms can include severe anaemia, intense pain, damage to major organs and infections. These episodic periods of pain are sometimes called ‘crises’. Although there is no routine cure for sickle cell, it can be managed to reduce the frequency and severity of crises and their complications by prompt recognition and treatment

The error in the hemoglobin gene results from a genetic mutation that occurred many thousands of years ago in people in parts of Africa, the Mediterranean basin, the Middle East, and India. A deadly form of malaria was very common at that time, and malaria epidemics caused the death of great numbers of people. Studies show that in areas where malaria was a problem, children who inherited one sickle hemoglobin gene and who, therefore, carried the sickle cell trait - had a survival advantage.

It is estimated that over 2 million people suffer from sickle cell disease, worldwide. It is particularly common among people whose ancestors come from sub- Saharan Africa; Spanish speaking regions (South America, Cuba, Central America); Saudi Arabia; India; and Mediterranean countries, such as Turkey, Greece, and Italy. In this country, it affects approximately 72,000 people, most of whose ancestors, come from Africa.

Early diagnosis of sickle cell anemia is critical. Early detection, education, and the use of penicillin may reduce life-threatening complications. More than 40 states now perform a simple, inexpensive blood test for sickle cell disease on all newborn infants. This test is performed at the same time and from the same blood samples as other routine newborn screening tests. Hemoglobin electrophoresis is the most widely used diagnostic test.

Although there is no cure for sickle cell anemia, doctors can do a great deal to help sickle cell patients, and treatment is constantly being improved. Basic treatment of painful crises relies heavily on pain-killing drugs and oral and intravenous fluids to reduce pain and prevent complications. Blood transfusions are used to treat and to prevent some of the complications of sickle cell anemia. Transfusions correct anemia by increasing the number of normal red blood cells in circulation.

You can donate blood if you have sickle cell trait. However, all blood is currently filtered to help prevent reactions in the recipient. Blood with sickle cell trait does not filter well. We encourage donors with sickle cell trait to donate plasma or platelet apheresis. These two types do not get filtered

Answer: If food is taken in moderation and with a generally balanced selection of foods, I cannot think of many foodstuffs that would be hazardous to somebody with sickle cell disease. Possible harm from excess iron if somebody already has iron overload from multiple transfusions - so there is generally no need for iron supplements in sickle cell disease.

The clinical course of sickle cell anemia does not follow a single pattern; some patients have, mild symptoms, and some have very severe symptoms. However, the basic problem is the same - the sickle-shaped red blood cells tend to get stuck in narrow blood vessels, blocking the flow of blood and oxygen.

The first effective drug treatment for adults with severe sickle cell anemia was reported in early 1995, when a study conducted by the National Heart, Lung, and Blood Institute showed that daily doses of the anticancer drug hydroxyurea reduced the frequency of painful crises and of acute chest syndrome in these patients. Patients taking the drug also needed fewer blood transfusions.

Scientists have learned a great deal about sickle cell anemia during the past 30 years - what causes it, how it affects the patient, and how to treat some of the complications. They also have begun to have success in developing drugs that will prevent the symptoms of sickle cell anemia and procedures that should ultimately provide a cure. Some researchers are focusing on identifying drugs that will increase the level of fetal hemoglobin in the blood.

In many western countries the sickle cell test is done when babies are born. The simple blood test will detect sickle cell disease or sickle cell trait. Testing is done in patients with a family history of sickle cell anemia. Testing is carried on in pregnant women to establish whether the fetus has sickle cell disease in which case termination of the pregnancy can be done.

Answer: Hydroxyurea therapy for pediatric sickle cell patients is in transitionzone between "experimental therapy" and "commonly accepted therapy." In comparison to adult sickle cell patients, the number of pediatric patients treated with hydroxyurea has been small. More teenagers have been treated with hydroxyurea than younger children.

Yes. By sampling the amniotic fluid or tissue taken from the placenta, doctors can tell whether a fetus has sickle cell anemia or sickle cell trait. This test can be done as early as the first trimester I of pregnancy.

Sickle Cell Anemia is clearly manifested at an early age. The child becomes pale, tires easily, eats poorly, may have swelling of the hands and feet, slow growth, pain in arms, legs, back and abdomen.

A crisis is a period in which the symptoms become severe. For variable periods, persons although chronically anemic, may go along without any complaints. Then with an attack of tonsilitis or common cold, or sometimes for no apparent reason, they become acutely ill and experience pain lasting from a few days to a week or two. The first sign of a crisis is usually loss of appetite, followed by paleness, weakness and fever.

The sickled red blood cells have a shorter life span than normal red blood cells and are easy to break, thereby causing the blood count to be lower than normal (anemia). The body cannot make new cells fast enough to keep up with the destruction. Therefore, the blood count remains below normal throughout life.

No cure has been found yet, but scientists are working to find a cure. Research and education are among top priorities in sickle cell programs funded through the National Heart and Lung Institute.

Infections are treated with antibiotics at the earliest moment, particularly in children. Drinking an adequate amount of fluids is encouraged at all times. Blood transfusions and exchange transfusions are sometimes needed. The treatment varies depending upon the organs involved and the nature of the complication. You must consult your physician for physical checkups and follow up care. Sickle Cell Anemia cannot be corrected with iron medication or foods containing iron.

Sickle cell disease is an inherited blood disorder that turns normal, round blood cells into misshaped cells that look like sickles or crescent moons. These sickled cells can get stuck in blood vessels, blocking blood flow and causing severe pain as well as damage to organs, muscles, and bones. See illustrations of hemoglobin function in a normal red blood cell and of a sickled red blood cell .

Sickle cell disease, a group of blood disorders, is inherited, passed from parent to child. Children with sickle cell disease have two defective genes, one from each parent. A child born with sickle cell trait inherited one defective gene from one parent, and a normal gene from the other parent. These children don't have sickle cell disease but are carriers of the defective gene and may pass it on to their children.

Your health professional can diagnose sickle cell disease through the results of blood tests that look for the presence of sickle cell hemoglobin. Some states have screening programs for newborns. Results of a simple blood test before infants go home from the hospital show whether or not the disease is present. Diagnosis can also occur before birth when the child is still in the womb.1
