View clinical trials related to Anemia, Sickle Cell.
Filter by:To continue to follow the newborn cohort and the over-35 years of age cohort from the Cooperative Study of Sickle Cell Disease (CSSCD), a study of the natural history of sickle cell disease.
To determine the natural history of sickle cell disease from birth to death in order to identify those factors contributing to the morbidity and mortality of the disease.
OBJECTIVES: I. Evaluate the efficacy and tolerability of fructose administered every 6 hours for up to 72 hours to patients in active sickle cell crisis. II. Obtain tolerability information in selected patients treated with fructose for more than 72 hours.
OBJECTIVES: I. Compare the efficacy of hydroxyurea with or without clotrimazole in terms of limiting the severity of anemia and the rate of hemolysis in patients with sickle cell anemia.
RATIONALE: Sickle cell disease is an inherited disorder in which abnormal, crescent-shaped red blood cells interfere with the ability of the blood to carry oxygen through the body and can cause severe pain, stroke, and organ damage. Bone marrow transplantation, is a procedure in which the soft, sponge-like tissue in the center of bones producing white blood cells, red blood cells, and platelets is replaced by bone marrow from a another person. Bone marrow transplantation may be an effective treatment in relieving the symptoms of sickle cell disease. PURPOSE: Phase I/II trial to study the effectiveness of bone marrow transplantation in treating children who have sickle cell disease.
OBJECTIVES: I. Compare the efficacy of local care alone vs local care plus arginine butyrate in terms of healing rate in patients with refractory sickle cell ulcers. II. Determine the effect of arginine butyrate therapy on tissue factors related to promotion or inhibition of wound healing in these patients. III. Determine whether the regimen used in this study is appropriate for testing in pivotal trials.
OBJECTIVES: I. Assess the efficacy of poloxamer 188 in reducing the duration of painful vaso-occlusive crisis in patients with sickle cell disease. II. Assess the effect of poloxamer 188 on duration and intensity of pain, total analgesic use, and length of hospitalization of these patients.
OBJECTIVES: Determine the effectiveness of the combined use of clotrimazole and hydroxyurea on a specific panel of red cell characteristics in patients with sickle cell syndromes.
RATIONALE: Although used primarily to treat malignant disorders of the blood, allogeneic stem cell transplantation can also cure a variety of non-cancerous, inherited or acquired disorders of the blood. Unfortunately, the conventional approach to allogeneic stem cell transplantation is a risky procedure. For some non-cancerous conditions, the risks of this procedure outweigh the potential benefits. This protocol is designed to test a new approach to allogeneic stem cell transplantation. It is hoped that this approach will be better suited for patients with non-cancerous blood and bone marrow disorders.
Sickle cell anemia is the most common genetic disease affecting African-Americans. About 1 in every 1000 African-Americans has the disease and 1 in every 12 carry the genes that could be passed on to their children. People with sickle cell anemia have abnormal hemoglobin, the molecules responsible for carrying oxygen in the blood. The abnormal hemoglobin can cause damage to the red blood cells. The damaged red blood cell may then stick in the blood vessels and cause pain and injury to organs. Some of the complications caused by the sticking of blood cells are called acute pain crisis and acute chest syndrome (ACS). Nitric oxide (NO) is a gas that has been proposed as a possible therapy for the ACS complication of sickle cell anemia. Studies have shown that NO may favorably affect sickle cell hemoglobin molecules, thereby improving blood flow through small vessels. This study is designed to evaluate the effects of NO, when taken in combination with a drug called nitroglycerin on patients with sickle cell anemia and normal volunteers. The effects of these two drugs only last while the patient is receiving them. Researchers hope the information learned from this study will help to develop new therapies for sickle cell anemia.
