Filter by:Background: - Some people with sickle cell disease have different health problems than others. This may be related to how easily and frequently the red blood cells break apart in the blood. Researchers want to test breath and blood samples from people with sickle cell disease to look for very small amounts of carbon monoxide, which is produced when red blood cells break apart. They will compare these results with breath samples from healthy volunteers. Studying different levels of carbon monoxide may help predict what health problems a person with sickle cell disease may get. It may also provide more information on possible treatments. Objectives: - To study breath carbon monoxide levels and their possible relation to the severity of sickle cell disease. Eligibility: - Individuals at least 18 years of age with sickle cell disease. - Healthy volunteers who are matched for age, sex, and race with the sickle cell disease group. Design: - Participants will be screened with a medical history. - Participants with sickle cell disease will provide a blood sample and have a heart function test. They will also breathe into a bag to provide an exhaled breath sample. - Healthy volunteers will provide an exhaled breath sample. - No treatment or care will be provided as part of this study.
The purpose of this study is to estimate the incidence of Pure Red Cell Aplasia (PRCA), neutralising antibodies, lack of efficacy, and thromboembolic events under treatment with Retacrit™ (epoetin zeta) administered subcutaneously in patients with renal anaemia. The other key objective of this study is to obtain information on adverse drug reactions (ADR) associated with Retacrit™ (epoetin zeta), use of epoetin zeta during pregnancy and lactation and data on long term use.
To assess the tolerability and efficacy of rabbit antithymocyte globulin (ATG, Thymoglobuline®) with ciclosporin (CSA) in the first line treatment of patients with acquired severe aplastic anaemia (SAA), and patients with non-severe aplastic anaemia (NSAA) and who are transfusion dependent. To compare the response rate of the combination of rabbit ATG (Thymoglobuline® and CSA from this pilot study with the response rate observed in a series of matched AA patients; treated after 1994 with the combination of horse ATG (Lymphoglobuline®) and CSA; obtained from the EBMT database (comparative study).
This phase II trial studies how well giving fludarabine phosphate, melphalan, and low-dose total-body irradiation (TBI) followed by donor peripheral blood stem cell transplant (PBSCT) works in treating patients with hematologic malignancies. Giving chemotherapy drugs such as fludarabine phosphate and melphalan, and low-dose TBI before a donor PBSCT helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from the donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cell from a donor can make an immune response against the body's normal cells. Giving tacrolimus, mycophenolate mofetil (MMF), and methotrexate after transplant may stop this from happening
The purpose of this study is to use comprehensive exercise testing to examine causes of exercise limitation in children and young adults with sickle cell anemia.
The purpose of this study is to assess the effect of the anti-hepcidin Spiegelmer NOX-H94 on iron homeostasis during systemic inflammation induced by endotoxin. In the human endotoxemia model, intravenously administered lipopolysaccharide elicits an inflammatory response with release of pro-inflammatory cytokines, such as IL-6 and TNF-alfa, with subsequent induction of hepcidin. As a consequence of hepcidin induction, serum iron concentrations decrease. This study in healthy subjects investigates the capacity of NOX-H94 to inactivate hepcidin and to prevent serum iron decrease in a pathophysiological model prior to studying the efficacy of NOX-H94 in patients with anemia of chronic disease.
This comparative, open-label, multicenter, parallel-group study evaluated the effect of altitude on the dose requirements of Mircera (methoxy polyethylene glycol-epoetin beta) to achieve a target hemoglobin concentration of 11-12 grams per deciliter (g/dL) in participants with chronic renal anemia in pre-dialysis and dialysis. Four groups of participants, at sea level (below 50 meters) or an altitude above 1800 meters, and pre-dialysis or dialysis, received 50-250 micrograms (mcg) Mircera subcutaneously (SC), according to the local prescribing label.
The objective of this study is to evaluate the effectiveness of 1-year administration of laying-on-of-hands on the morbidity and mortality of patients with sickle cell disease in Africa.
The purpose of this study is to evaluate the possible association between postoperative anaemia and functional outcomes the first 2 weeks after primary hip arthroplasty. The investigators hypothesise that patients with a higher degree of postoperative anaemia have impaired postoperative rehabilitation as measured by standardized functional outcome tests.
Hydroxyurea (HU) is approved by the United States Food and Drug Administration (FDA) to treat adults with sickle cell anemia. Hydroxyurea has also been tested and used with children with sickle cell anemia. However, there are not many studies describing the disposition of drug in children less than 5 years old. The FDA has requested this study to better understand how children ages 2 to 17 years with sickle anemia absorb and eliminate the drug (this is called pharmacokinetics). The investigators will measure how much Hydroxyurea (HU) gets into the bloodstream at different time points after taking this medication.
