Extractions: Nitric oxide gas may treat, prevent sickle cell crisis September 2, 1997 Journal of Clinical Investigation, the new approach would be the first to attack directly the abnormal "sickle" hemoglobin that causes sickle cell crisis, a condition that currently can be treated only with pain-killing drugs. If follow-up studies prove successful, patients might someday treat or prevent sickle cell crisis symptoms by self-administering nitric oxide with inhalers similar to those used by asthma patients. "The effect of inhaled nitric oxide on sickle hemoglobin is totally separate from its effects in the lungs, which have proven life-saving for people with several critical illnesses," says C. Alvin Head, MD, the MGH anesthesiologist who led the study. "This is a totally new application of this molecule, which has generated a lot of interest over the past several years." Study co-author Kenneth Bridges, MD, director of the Joint Center for Sickle Cell and Thalassemic Disorders at Brigham and Women's Hospital and the MGH, adds, "This discovery gives us two things: a possible means of interrupting sickle cell crisis once it's started — something we don't have right now — and a real possibility for long-term, outpatient treatment." In sickle cell disease, a genetic disorder, affected individuals have an abnormal form of hemoglobin, the protein in red blood cells that carries oxygen from the lungs to tissues and organs throughout the body. After this abnormal hemoglobin releases its oxygen, it clumps together into an abnormal shape, deforming the red blood cells — normally flexible discs — into rigid, elongated "sickle cells." These sickle cells can become stuck in tiny blood vessels, blocking blood flow to various parts of the body. The result is sickle cell crisis, excruciating pain in the affected area that can require hospitalization in the most serious cases.

The therapy counteracts the faulty gene that causes red blood cells to "sickle" or deform, by transferring an anti-sickling variant of the gene to bone marrow with a viral delivery system. Once there, the anti-sickling gene incorporates itself into the stem cells that give rise to red blood cells. In two mouse models, the new gene was rapidly expressed in 99 percent of all circulating red blood cells, preventing sickling and other signs of the disease, says study author Philippe Leboulch of the Harvard Medical School and Massachusetts Institute of Technology.

Extractions: Sickle-Cell Disease December 1999 WHAT IS SICKLE-CELL DISEASE? Red blood cells carry oxygen throughout the body to nourish tissues and sustain life. They are the most abundant cells in the human body. When they are healthy, they look like tiny flexible inner tubes. This unique shape and small size serve many functions. The tubular shape provides a large surface area to absorb oxygen. It also offers the flexibility necessary to squeeze through the capillaries, the tiny blood vessels that connect arteries to veins. Oxygen is carried within the red blood cells by hemoglobin, a complicated molecule composed of proteins and iron. Sickle-cell disease is caused by a genetic defect in this important hemoglobin molecule. A normal red blood cell contains a molecule called hemoglobin A ; in a sickle red blood cell, a variant of this molecule exists and is called hemoglobin S (S for sickle). The difference between hemoglobin A (HbA) and hemoglobin S (HbS) lies in only one protein out of about three hundred that are common to both. This protein lies along an amino-acid chain called beta-globin, where even a tiny abnormality has disastrous results. The sickle-cell disease process is triggered when red blood cells become deprived of oxygen. In everyone, both those with and without the disease, hemoglobin loses its oxygen in a number of ways. To sustain life, oxygen regularly passes from red blood cells to the tissues where it is needed to perform vital functions. Hemoglobin loses oxygen if blood cells become too acidic, for example, after strenuous exercise. Going to high altitudes or any stressful activity or situation that increases the body's demand for oxygen depletes its supply in red blood cells. Such situations do not affect normal red blood cells that contain hemoglobin A. Oxygen loss from hemoglobin S, however, causes the molecules to form rigid rods called

Extractions: Ocular symptoms are uncommon in the early stages of the disease. Systemically, symptoms include painful crises of abdominal and musculoskeletal discomfort. Ocular signs include comma-shaped vessels in the bulbar conjunctiva, iris atrophy, iris neovascularization, dull-gray fundus appearance, retinal venous tortuosity, nonproliferative retinal hemorrhages in the subretinal, intraretinal or preretinal position. Further signs include black sunbursts (retinal pigment epithelial hyperplasia secondary to deep retinal vascular occlusions), glistening refractile deposits in the retinal periphery (hemosiderin-laden macrophages), salmon patch hemorrhages (orange-pink-colored intraretinal hemorrhage), angioid streaks (breaks in Bruch's membrane radiating from the optic nerve), venous occlusion, artery occlusion, peripheral neovascularization (seafan retinopathy) with subsequent vitreous hemorrhage and tractional retinal detachment. Hemoglobinopathies are among the more commonly inherited diseases in humans. Hemoglobinopathies result when there is altered structure, function or production of hemoglobin. Hemoglobin is the principle protein of the erythrocyte, responsible for binding and facilitating oxygen transmission to tissues. In the four variations of sickle cell disease, systemic and ocular tissues become deprived of oxygen and undergo pathologic changes.

Extractions: Sickle Cell Anemia Research Study If you are pregnant and expecting a baby that may have sickle cell disease you might be interested in our research study. We are collecting umbilical cord blood from newborns that may have sickle cell disease and we are freezing the hematopoietic stem cells that are in the cord blood. Hematopoietic stem cells are used in transplant treatment of sickle cell disease; the more cells the doctors use the better the outcome. The goal of our research is to come up with the best ways to harvest, freeze and thaw the stem cells from the umbilical cord blood so when it comes time to use the stem cells for treatment there will be a lot of high quality cells to use. To be eligible for this program the pregnant mother must be between the ages of 18 - 45 and she must plan to deliver her infant at a hospital in the Washington Metropolitan Area. The pregnant mother needs to attend a meeting with the nurse coordinator in order to go over the program and give consent before labor begins. There is no cost to the family or their insurance carrier for this program.

Extractions: Introduction Haemoglobin (Hb) is contained in red blood cells and is capable of combining with oxygen in the lungs, transporting it to the tissues and releasing it there. Normally it is composed of 4 polypeptide chains combined with 4 haem radicals ( see Table 1 ). When the haemoglobin is combined with oxygen it is said to be oxygenated. When it is not combined with oxygen it is deoxygenated (sometimes also called "reduced"). Sickle cell disease is a genetically inherited abnormality of haemoglobin in which valine (an amino acid) replaces glutamine at the sixth position on the beta chains of the haemoglobin molecule. This haemoglobin is termed Haemoglobin S (usually written HbS). Unfortunately when HbS becomes deoxygenated it comes out of solution forming long crystals called "tactoids" which distort the red cell. Two types of sickle cell illness are described depending on the genetic make-up. Everyone has 2 genes responsible for haemoglobin synthesis. When a person has one normal (HbA) gene and one sickle (HbS) gene they make a mixture of HbA and HbS. They are called heterozygous patients (meaning that they have both genes present) and are said to have

Extractions: Sickle Cell Disease is a hereditary blood disorder that affects the oxygen-carrying component of blood, the red blood cell. In other words, it is manifested by diseased red blood cells that have a sickle shape. Red blood cells have proteins called hemoglobin. Hemoglobin transports oxygen from your lungs to every part of your body. When a normal red blood cell (with normal hemoglobin) releases its oxygen, it maintains its discoid shape. However, when a diseased red blood cell containing sickle hemoglobin releases its oxygen, the appearance of the cell can change from discoid to sickle-shaped. This is to say that the sickle cell shape is caused by the sickle hemoglobin within a particular red blood cell. Possible health problems may include fatigue, breathlessness, rapid heartbeat, delayed growth, susceptibility to infections, skin ulcers, and vision problems. NORMAL HEMOGLOBIN vs. SICKLE HEMOGLOBIN While sickle hemoglobin and normal hemoglobin carry the same amount of oxygen, two major differences exist between the two kinds of cells. First, they differ in the way they flow through the blood vessels. Normal hemoglobin is found in disc-shaped red blood cells that are soft (like a bag of jelly), which enables them to easily flow through small blood vessels. Diseased red blood cells, which are sickle-shaped and are hard (like pieces of wood), often get stuck in small blood vessels and stop the flow of blood. The second difference between the two types of cells is their longevity. Sickle cells do not live as long as normal cells. Normal, healthy cells can survive for about 120 days, while the more fragile sickle cells can survive for about 60 days or less. Unfortunately, the body cannot make new red blood cells as fast as it loses sickle blood cells. As a result, a sickle cell patient has fewer red blood cells and less hemoglobin than normal red blood cells. This decreased hemoglobin (called anemia), in turn, results in less oxygen being available for use by the cells of the body.

http://www.larabida.org/patients/sickle.html

Extractions: Medical Staff Sickle Cell Disease is a genetic disorder affecting more than one in 500 African American children in the United States. It causes red blood cells to become crescent or sickle shaped instead of round, inhibiting the delivery of oxygen from the lungs to the rest of the body. As a result, patients may become easily tired or experience severe pain crises when the sickle cells clump together in the blood vessels. Maintaining control of the condition can decrease the occurrence and severity of these episodes, and help children and families manage more successfully with the disease. La Rabida provides interdisciplinary medical and support services to address the special needs of children with sickle cell disease and their families on both an inpatient and outpatient basis. La Rabida's staff manages all types of sickle cell disease such as sickle cell anemia, sickle C disease, and sickle-beta thalassemia conditions. Upon diagnosis, each patient with sickle cell disease receives an individualized program of treatment from an interdisciplinary team of specialists. This team includes hematology and chronic disease physicians, nurse specialists, a psychologist, and social worker when needed. In addition, the team may also provide genetic counseling, sickle cell disease management, parent and family education, and an innovative program of behavioral pain management.

Extractions: CNN.com Health Writer ATLANTA, Georgia (CNN) - Although research continues, sickle cell anemia remains an "orphan disease" attracting little notice despite its harvest of pain and early death. But a new film documentary may help to educate viewers about the disease, which affects about 80,000 people in the United States and millions worldwide. Called "Sickle Cell: The Forgotten Disease," the film will air at 10 p.m. EST on the Discovery Health Channel. It is being co-produced by the Dr. Spock Company. "It's hard to get funding or people interested in trials," said Dr. James Eckman, director of the Georgia Comprehensive Sickle Cell Center at Grady Health System. "But because this is a lifelong, chronic problem, it has a greater impact." CONDITION CLINIC Sickle Cell disease A genetic disorder, sickle cell disease attacks red blood cells, making them rigid and distorting their normally round shape into crescents and points. These misshapen cells can easily clog tiny blood vessels and deprive organs and tissues of vital oxygen, causing intractable pain crises. In addition, children with sickle cell are more prone to stroke, pneumonia, infection and other long-term complications.
