What You Should Know About Sickle Cell Trait Please watch the following video about Sickle Cell Trait: CATAWBA COLLEGE ATHLETIC TRAINING DEPARTMENT Sickle Cell Trait Testing About Sickle Cell Trait - - Sickle cell trait is an inherited condition of the oxygen-carrying protein, hemoglobin, in the red blood cells. - Sickle cell trait is a common condition (> three million Americans) - Although Sickle cell trait is most predominant in those of African, Mediterranean, Middle Eastern, Indian, Caribbean, and South and Central American ancestry, persons of all races, sex and ancestry may test positive for sickle cell trait. - Sickle cell trait is usually benign, but can be life-threatening, especially during intense, sustained exercise, hypoxia (lack of oxygen) in the muscles may cause sickling of red blood cells (red blood cells changing from a normal disc shape to a crescent or “sickle” shape), which can accumulate in the bloodstream and “logjam” blood vessels, leading to rhabdomyolysis which is a collapse from the rapid breakdown of muscles starved of blood. For more information on Sickle Cell: http://web1.ncaa.org/web_files/health_safety/SickleCellTraitforSA.pdf Sickle Cell Trait Testing – - The NCAA mandates that all NCAA student-athletes have knowledge of their sickle cell trait status before the student-athlete participates in any intercollegiate athletics event, including strength and conditioning sessions, practices, competitions, etc. - The Catawba College Department of Intercollegiate Athletics offers sickle cell trait screening in the form of a blood test to all student-athletes for a nominal fee through the on-campus Student Health Services. - Testing will be conducted at the Catawba College Student Health Center and through a local designated laboratory facility and results will be reported to the student-athlete, Student Health Center, the Athletic Training Staff and the team physicians. - If you have already been tested for sickle cell trait, please provide a copy of the written results to the Athletic Training Department. Sickle Cell Testing Compliance All Catawba Freshmen and Transfer Student-Athletes must show proof of mandatory Sickle Cell Testing by attaching a copy of a diagnostic lab report! Acceptable laboratory reports include Hemoglobin Solubility Test, Hemoglobin Electrophoresis, or High Performance Liquid Chromatography, (HPLC). A copy of the Sickle Cell Test done at birth is also acceptable to meet this requirement. What You Should Know About Sickle Cell Disease What Is Sickle Cell Disease? Sickle cell disease (SCD) is a group of inherited red blood cell disorders. • Healthy red blood cells are round and they move through small blood vessels carrying oxygen to all parts of the body. • In SCD, the red blood cells become hard and sticky and look like a C-shaped farm tool called a “sickle”. • Sickle cells die early, which causes a constant shortage of red blood cells. • Sickle cells can get stuck in small blood vessels and block the flow of blood and oxygen to organs in the body. These blockages cause repeated episodes of severe pain, organ damage, serious infections, or even stroke. What Causes Sickle Cell Disease? SCD is inherited in the same way that people get the color of their eyes, skin, and hair. • A person with SCD is born with it. • People cannot catch SCD from being around a person who has it. Who Is Affected By Sickle Cell Disease? • It is estimated that SCD affects 90,000 to 100,000 people in the United States, mainly Blacks or African Americans. • The disease occurs among about 1 of every 500 Black or African- American births and among about 1 out of every 36,000 Hispanic- American births. • SCD affects millions of people throughout the world and is particularly common among those whose ancestors come from sub- Saharan Africa; regions in the Western Hemisphere (South America, the Caribbean, and Central America); Saudi Arabia; India; and Mediterranean countries such as Turkey, Greece, and Italy. What Health Problems Does Sickle Cell Disease Cause? Following are some of the most common complications of SCD: “Pain Episode” or “Crisis”: Sickle cells don’t move easily through small blood vessels and can get stuck and clog blood flow. This causes pain that can start suddenly, be mild to severe, and last for any length of time. Infection: People with SCD, especially infants and children, are more likely to experience harmful infections such as flu, meningitis, and hepatitis. Hand-Foot Syndrome: Swelling in the hands and feet, often along with a fever, is caused by the sickle cells getting stuck in the blood vessels and blocking the blood from flowing freely through the hands and feet. Eye Disease: SCD can affect the blood vessels in the eye and lead to long term damage. Acute Chest Syndrome (ACS): Blockage of the flow of blood to the lungs can cause acute chest syndrome. ACS is similar to pneumonia; symptoms include chest pain, coughing, difficulty breathing, and fever. It can be life threatening and should be treated in a hospital. Stroke: Sickle cells can clog blood flow to the brain and cause a stroke. A stroke can result in lifelong disabilities and learning problems.

The goals of treating SCD are to relieve pain and to prevent infections, eye damage, and strokes. • There is no single best treatment for all people with SCD. Treatment options are different for each person depending on the symptoms. Treatments can include receiving blood transfusions, maintaining a high fluid intake (drinking 8 to 10 glasses of water each day), receiving IV (intravenous) therapy (fluids given into a vein) and medications to help with pain. • For severe SCD, a medicine call hydroxyurea might be recommended. Research suggests that hydroxyurea can reduce the number of painful episodes and the recurrence of ACS. It also can reduce hospital stays and the need for blood transfusions among adults who have SCD. Is There A Cure For Sickle Cell Disease? To date, the only cure for SCD is a bone marrow or stem cell transplant. • A bone marrow or stem cell transplant is a procedure that takes healthy stem cells from a donor and puts them into someone whose bone marrow is not working properly. These healthy stem cells cause the bone marrow to make new healthy cells. • Bone marrow or stem cell transplants are very risky, and can have serious side effects, including death. For the transplant to work, the bone marrow must be a close match. For more information visit: www.cdc.gov/sicklecell What You Should Know About Sickle Cell Trait What Is Sickle Cell Trait? What Are The Chances Sickle cell trait (SCT) is not a mild form of sickle cell disease. That A Baby Will Have Having SCT simply means that a person carries a single gene for sickle cell disease (SCD) and can pass this gene along to Sickle Cell Trait or their children. People with SCT usually do not have any of the Sickle Cell Disease? symptoms of SCD and live a normal life. Hemoglobin is found in red blood cells and it gives blood its color. It carries oxygen to all parts of the body. Hemoglobin is made from two similar proteins, one called alpha-globin and one called beta-globin, that “stick together.” Both proteins must be present and function normally for the hemoglobin to carry out its job in the body. People with SCT have red blood cells that have normal hemoglobin and abnormal hemoglobin. Genes are the instructions that control how red blood cells make alpha- and beta-globin proteins. All people have two genes for making beta-globin. They get one beta-globin gene from each parent. SCT occurs when a person inherits a gene for sickle beta- globin from one parent and a gene for normal beta-globin from the other parent. This means the person won’t have sickle cell disease, but will be a trait “carrier” and can pass it on to their children. What Is Sickle Cell Disease? SCD is a genetic condition that is present at birth.

  • Sickle Cell: It's Your Choice
    Sickle Cell: It’s Your Choice What Does “Sickle Cell” Mean? Sickle is a type of hemoglobin. Hemoglobin is the substance that carries oxygen in the blood and gives blood its red color. A person’s hemoglobin type is not the same thing as blood type. The type of hemoglobin we have is determined by genes that we inherit from our parents. The majority of individuals have only the “normal” type of hemoglobin (A). However, there are a variety of other hemoglobin types. Sickle hemoglobin (S) is one of these types. There Are Two Forms of Sickle Cell. Sickle cell occurs in two forms. Sickle cell trait is not a disease; Sickle cell anemia (or sickle cell disease) is a disease. Sickle Cell Trait (or Sickle Trait) Sickle cell trait is found primarily in African Americans, people from areas around the Mediterranean Sea, and from islands in the Caribbean. Sickle cell trait occurs when a person inherits one sickle cell gene from one parent and one normal hemoglobin gene from the other parent. A person with sickle cell trait is healthy and usually is not aware that he or she has the sickle cell gene. A person who has sickle trait can pass it on to their children. If one parent has sickle cell trait and the other parent has the normal type of hemoglobin, there is a 50% (1 in 2) chance with EACH pregnancy that the baby will be born with sickle cell trait. When ONE parent has sickle cell trait, the child may inherit: • 50% chance for two normal hemoglobin genes (normal hemoglobin- AA), OR • 50% chance for one normal hemoglobin gene and one sickle cell gene (sickle cell trait- AS).

  • Genetics: Sickle Beta Plus Thalassemia
    Genetics: Sickle beta plus thalassemia Sickle beta plus thalassemia (THAL-UH-SEE-ME-AH) is a blood condition that is similar to sickle cell anemia. Sickle cell anemia is a disease that causes red blood cells (RBCs) to have an abnormal shape. Sickle red blood cells can get stuck in blood vessels and block the flow of blood and oxygen in the body. When this happens is can cause severe pain, serious infections, organ damage, or even stroke. What is hemoglobin and what does it do? Red blood cells contain hemoglobin (HEE-MUH-GLOW-BIN). Hemoglobin is a protein that carries oxygen around the body. There are several types of abnormal hemoglobin. Sickled hemoglobin is the type that causes sickle cell anemia. It is usually written as Hb-S. Beta thalassemia causes your child's body to make less normal hemoglobin (Hb-A). When this happens, your child's body makes more sickled cells and has symptoms similar to sickle cell anemia. The amount of sickled cells is different in each child with beta thalassemia. When a person has one copy of Hb-S and one copy of beta thalassemia, it is called sickle beta thalassemia. In general, people who have sickle beta plus thalassemia make more normal hemoglobin than people who have sickle beta zero thalassemia. How does a person get sickle beta plus thalassemia? Sickle beta thalassemia is genetic disorder, meaning it is passed on from parents to their children just like hair, eye, and skin color. You are born with sickle beta thalassemia disease. It is not contagious.

A technique has been developed for the determination of reactive membrane sulfhydryl content in intact erythrocytes, utilizing sub­ hemolytic concentrations of p-chloromercuribenzoate (PMB). The erythrocyte membrane of 52 healthy subjects contained 2.50 - 2.85 x lo-16 moles of reactive SH groups ( mean 2.50 ·~ 0.20 ) per erythrocyte, when determined by this method. A 27-56% reduction of erythrocyte membrane SH content was observed in various conditions characterized by accelerated red cell destruction, including glucose- 6-phosphate dehydrogenase ( G6PD ) deficiency, drug-induced, auto- immune and other acquired hemolytic anemias and congenital spherocytosis. Normal membrane sulfhydryl content was found in iron deficiency anemia, pernicious anemia in relapse, and in other miscellaneous hematological conditions. Inhibition of membrane SH groups with PMB caused marked potassium leakage from the otherwise intact cells. The possible role of membrane suli'hydryl groups in the development of certain types of hemolytic anemias,and in the maintenance of active transmembrane cation transport in the erythrocyte is discussed.
