Filter by:Safety, tolerability, pharmacokinetics and pharmacodynamics will be investigated in a single dose group stratified study in renal impaired and healthy subjects.
Background: - Chronic leg ulcers are a complication of many blood disorders such as sickle cell disease, thalassemia, and other red blood cell disorders. In these disorders, red blood cells break down earlier than normal, which researchers suspect may cause or contribute to the development of leg ulcers; however, the exact cause is unknown, and current therapies are not very effective. Researchers are interested in determining if a research cream made with sodium nitrite, a substance that is known to increase blood flow by dilating blood vessels, may speed up the healing of skin ulcers. Objectives: - To evaluate the safety and effectiveness of topical sodium nitrite cream as a treatment for chronic leg ulcers in individuals with sickle cell disease or other red blood cell disorders. Eligibility: - Individuals at least 18 years of age who have sickle cell disease or another red cell disorder and have had a leg ulcer for more than 4 weeks. Design: - Participants will be screened with a physical examination, medical history, blood tests, and an examination of the ulcer, including x-ray of the leg(s) with the ulcer and swabs from the wound. - Participants will be scheduled for a 5-day inpatient stay at the Clinical Center, with the following procedures: - Days 1 and 2: Participants will have blood draws, a wound assessment, ultrasound of the affected leg, imaging studies (magnetic resonance imaging and infrared photography), thermo-patch application to monitor temperature changes, measurements of blood flow in the skin, and questionnaires about pain and quality of life. An optional skin biopsy may also be conducted with samples taken near the skin ulcer - Day 3: Participants will have one ulcer treated with the topical cream. Frequent blood draws will be conducted before application and then regularly for up to 6 hours after application of the cream. Thirty minutes after the research cream is applied, participants will have imaging studies of the treated leg and measurements of pain levels and blood flow. - Day 4: Participants will have a blood draw and temperature recordings taken. - Day 5: Participants will have the research cream applied and the same imaging studies as before, and will be discharged for care at home. - For the following 3 weeks, participants will come to the clinical center twice a week to have the research cream applied to the leg ulcer and tests performed by the study researchers. - For the fourth and final week, participants will return for additional cream treatment sessions, imaging studies, blood draws, and other tests as directed by the study researchers. - Study participation will end in the following week (week 5). Subjects will come for a final visit one month after the end of the study.
Establishing a Data Base for Aplastic Anemia and Other Marrow Failure Syndrome
The purpose of this study is to determine whether treatment of unexplained anemia in older adults with a short course of weekly intravenous iron infusions can improve physical activity and therefore quality of life.
This observational study will assess the effect of long-term treatment with Mircera (methoxy polyethylene glycol-epoetin beta) in chronic kidney disease patients with renal anemia. Data will be collected from each patient for at least 24 months.
The purpose of this study is to gain information on reticulocyte neocytolysis in patients treated with ESA with regard to different types of ESA.
The study is a phase I/II trial designed to establish the safety and efficacy of intravenous administration of bone marrow derived mesenchymal stem cells from related donor to patients with relapsed/refractory aplastic anemia.
Mesenchymal stem cells have been tested in many autoimmune disorders with encouraging results and may be an alternative to the treatment of immune-mediated severe acquired aplastic anemia.
The primary purpose of this study is to determine the effect of Epoetin Alfa (Procrit) on the change in hemoglobin (red blood cell count) in anemic kidney transplant recipients. The investigators hypothesize that epoetin alfa will raise hemoglobin.
The purpose of this study is to compare safety and the oxidative stress potential of two doses of an investigational IV iron, ferric carboxymaltose (FCM), compared to an equal single dose of IV iron sucrose or IV iron dextran in the treatment of Iron Deficiency Anemia (IDA) in female subjects.
