Filter by:Background: - Severe aplastic anemia is a rare and serious blood disorder. It happens when the immune system starts to attack the bone marrow cells. This causes the bone marrow to stop making red blood cells, platelets, and white blood cells. Standard treatment for this disease is horse-ATG and cyclosporine, which suppress the immune system and stop it from attacking the bone marrow. However, this treatment does not work in all people. Some people still have poor blood cell counts even after treatment. - Eltrombopag is a drug designed to mimic a protein in the body called thrombopoietin. It helps the body to make more platelets. It may also cause the body to make more red and white blood cells. Studies have shown that eltrombopag may be useful when added to standard treatment for severe aplastic anemia. It may help improve poor blood cell counts. Objectives: - To test the safety and effectiveness of adding eltrombopag to standard immunosuppressive therapy for severe aplastic anemia. Eligibility: - Individuals at least 2 years of age who have severe aplastic anemia that has not yet been treated. Design: - Participants will be screened with a physical exam, medical history, and blood tests. Blood and urine samples will be collected. - Participants will start treatment with horse-ATG and cyclosporine. Treatment will be given according to the standard of care for the disease. - Cohort 1: After 14 days, participants will start taking eltrombopag. They will take eltrombopag for up to 6 months. - Cohort 2: After 14 days, participants will start taking eltrombopag. They will take eltrombopag for up to 3 months. - Cohort 3 and Extension Cohort: Participants will start taking eltrombopag on Day 1. They will take eltrombopag for up to 6 months. - Participants may receive other medications to prevent infections during treatment. - Treatment will be monitored with frequent blood tests. Participants will also fill out questionnaires about their symptoms and their quality of life.
Impact exerted by intestinal parasitic infections is much higher in developing countries. School-aged children are at higher risk from the burden of disease, because they specially have many parasitic infections. The poor health results in deficits in physical and cognitive development and educational achievements. Nowadays, there is huge commitment among the global community to control intestinal parasitic infections and to improve nutritional status of young children in developing countries. Large-scale anthelminthic drug administration through vertical control programmes is still required for the foreseeable future and is, therefore, recommended by the World Health Organization (WHO). However, due to the inevitability of re-infection in endemic areas, children need to be treated regularly, and once morbidity control is consolidated, the strategy must shift to transmission control emphasising access to clean water and adequate sanitation. To lower dependency on 'drug only' approach and to enhance sustainability, from the onset of control activities, complementary measures should be implemented, that depend on available resources. Therefore, the investigators are proposing to undertake a randomised controlled trial to assess the impact of simple and easy-to-do hand hygiene intervention packages (hand washing with soap and hand finger nail clipping) on intestinal parasitic infection prevalence, intensity and re-infection rates and on haemoglobin concentration and anaemia prevalence rates among 6-15 years old schoolchildren. Our results will provide solid evidence on if and how hand hygiene practice affects infection prevalence and re-infection rates, as well as, anaemia prevalence among the highly vulnerable age group.
The aim of the ETPOS study is to describe differences in transfusion habits throughout Europe and to correlate these habits to perioperative outcome parameters. Special focus is put on the number of PRBCs (packed red blood cells) transfused and the ratio of PRBCs to other blood products or coagulation factors in the operating room. Furthermore the motivation of physicians to transfuse PRBC and blood products in the operating room will be investigated.
The purpose of this study is to investigate whether a validated sensor that is able to measure how much oxygen-carrying molecules called hemoglobin using pulse hemoglobin and Pleth Variability Index (PVI)] are in your blood during surgery can help your doctors manage how much fluid and possibly blood you need to get during your surgery. The hope of the study is that the device may provide an early indication you are having bleeding and this may mean you need to be treated with a transfusion. Our current method of checking this is by getting a blood sample for analysis. The investigators hope is that this device may be able to alert the clinician of the need for blood or fluids without a blood draw being needed.
Anemia of inflammation (AI), a normochromic, normocytic anemia, associated with abnormal iron utilization, erythropoietin hyporesponsiveness, and decreased red blood cells (RBC) survival is a very common problem in hospitalized patients for acute inflammatory diseases and develops within few days from the onset of illness. Deleterious effects of anemia include increased risk of cardiac related morbidity and mortality in critically ill and older patients. Anemia is mediated by hepcidin, the 25-amino acid polypeptide hormone that is central to iron trafficking. Several studies have been performed on pathophysiology of AI in patients affected by chronic diseases but few explore iron metabolism in humans with acute inflammation. The aim is to develop effective new strategies to detect and manage AI in the setting of acutely ill patients, based on the understanding of iron balance underlying this disorder.
This is a four-week, Phase IIa, randomized, active-controlled, parallel-group, multi-center study to evaluate the safety, efficacy and pharmacokinetics of switching subjects from stable rhEPO to GSK1278863 in approximately 68 hemodialysis-dependent subjects with anemia associated with chronic kidney disease. The study consists of a screening phase of 2 weeks, a 4-week treatment phase and a 2-week follow-up phase. The range of Hgb values for study eligibility is 9.5-12.0 g/dL and the subjects must have received the same rhEPO product with total weekly doses that varied by no more than 50% during the 4 weeks prior to the Screening visit (Week -1. This study aims to estimate the relationship between dose of GSK1278863 and Hgb response in hemodialysis-dependent (HDD) subjects with anemia associated with chronic kidney disease after switching from a stable maintenance dose of recombinant human erythropoetin (rhEPO).
This is a four-week Phase IIa, randomized, double-blind, placebo-controlled, parallel-group, multi-center study to evaluate the safety, efficacy and pharmacokinetics of GSK1278863 in approximately 68 subjects with anemia associated with chronic kidney disease who are not taking rhEPO and are not undergoing dialysis. The range of Hgb values for study eligibility is 8.5-11.0 g/dL. Eligible subjects will be randomized in equal proportions to receive once daily (QD) placebo or GSK1278863 0.5 mg, 2 mg or 5 mg in a double-blind fashion.
The hypothesis of this study is that prolonged-storage RBCs are not inferior to short-storage RBCs for the time required to clear elevated blood lactate levels in children with severe anemia.
The purpose of this clinical trial is to investigate the safety of human placental-derived stem cells (HPDSC) given in conjunction with umbilical cord blood (UCB) stem cells in patients with various malignant or nonmalignant disorders who require a stem cell transplant. Patients will get either full dose (high-intensity) or lower dose (low intensity) chemo- and immunotherapy followed by a stem cell transplantation with UCB and HPDSC.
Multiple births in the United States are rapidly increasing in large part due to assisted reproductive technologies. Recent data indicate that multiple births now comprise 3-4.5% of all births in the United States. Pregnant women are at risk for iron (Fe) deficiency anemia yet there are virtually no data on Fe status in women carrying multiples and current recommendations do not necessitate Fe screening among this high risk group. Maternal anemia is known to increase the risk of adverse birth outcomes including preterm birth and low birth weight. Moreover, the developing brain is increasingly recognized to be susceptible to Fe insufficiency in utero and growing data support that suboptimal Fe stores at birth are associated with long-term irreversible cognitive deficits in the offspring. To address these gaps in knowledge the investigators will monitor weight gain, hematological measures, Fe status indicators and serum hepcidin across pregnancy in approximately 120 women carrying twins and triplets. Determinants of maternal anemia will be identified. Neonatal hematological measures will be assessed in cord blood from each neonate at birth for assessment of hematological measures, Fe status and hepcidin. Determinants of neonatal anemia will be identified. Inflammatory markers will be measured in all blood samples and related to outcomes. Stable iron isotopes will be given to a subset of women to assess maternal Fe absorption and fetal Fe uptake.
