Evaluate potential sources of error that affect the accuracy of continuous hemoglobin monitoring.
This observational study will evaluate the efficacy and safety of NeoRecormon (epoetin beta) in cancer patients receiving chemotherapy. Patients receiving NeoRecormon once weekly in accordance with the Summary of Product Characteristics will be followed for 4 months.
The purpose of this registry is to record information of routine treatment of anemia in cancer patients in Germany. An overview of the current treatment of anemia in German outpatient centers and hospitals will be provided. Primary outcome parameters, e.g. improvement in hemoglobin levels and changes in QoL, as well as patient characteristics of different treatments will be analyzed.
Nutritional anemia is a major public health problem among children and women in developing countries. Despite ongoing national program of supplementing pregnant women with iron-folate, prevalence of anemia is 39% among pregnant women and 78% among infants in Bangladesh. Vitamin B12 deficiency is a more prevalent cause of megaloblastic anemia than folate in many developing countries. This data raises the interest to address the role of vitamin B12 deficiency in nutritional anemia. Low dietary intake of animal products, a predominant source of vitamin B12 may cause anemia. Besides maintaining normal erythropoiesis, B12 is essential for immune function. However, no studies have evaluated the effect of maternal B12 supplementation on reduction of anemia and improving immunity of their infants. The investigators hypothesize that vitamin B12 supplementation plus iron-folate during pregnancy and 3-mo postpartum would: (a) Decrease anemia among mothers and infants; (b) Improve vaccine specific cellular and humoral immune responses among mothers; (c) Improve vaccine specific immunity in infants by passive transfer; (d) Improve DNA methylation and one-carbon metabolism in mother-child pairs; (e) Reduce antenatal/postnatal depression. Results from this study will guide and provide support to the policy makers to identify effective strategies to reduce nutritional anemia in population at risk. The investigators aim to conduct a double-masked placebo controlled trial to investigate the added effect of vitamin B12 on the iron-folate supplementation among pregnant women. Anemic (Hb level <11.0 g/dl) mothers at 11-14 weeks of gestation will be randomized into two groups: supplement group will receive 250 ug vitamin B12 plus 400 ug folate and 60 mg iron; placebo group will receive folate and iron only. This daily supplementation will continue up to 3-mo postpartum. At 26-28 wk of gestation mothers will be given inactivated influenza vaccine. Data on anthropometric indices of mothers and children, birth size, infant growth and morbidity (mothers and children) throughout the study period will be recorded. 24-h dietary recall data will be collected from the mothers bimonthly throughout the study. Biochemical indicators of anemia including Hb, vitamin B12, ferritin, folate and α-glycoprotein (AGP) will be assessed in plasma of mothers (pre- and post-supplementation) and infants (cord blood and 3-months). Additional measurements include serum transferrin receptor (sTfR) in plasma and methyl malonic acid (MMA) and total homocysteine (tHcy) in the urine of mothers. Plasma vaccine specific antibody responses will be measured in mothers (pre- and post supplementation) and in infants (cord blood and 3-months). In breast milk, B12, folate and s-IgA will be determined. Genetic polymorphism (one-carbon metabolism) and DNA methylation will be studied in mothers and in cord blood.
This pilot phase II trial studies how well giving vorinostat, tacrolimus, and methotrexate works in preventing graft-versus-host disease (GVHD) after stem cell transplant in patients with hematological malignancies. Vorinostat, tacrolimus, and methotrexate may be an effective treatment for GVHD caused by a bone marrow transplant.
This research study is a Phase II clinical trial, which tests the safety and effectiveness of an investigational drug called Regadenoson (or Lexiscan) to learn whether the drug works in treating a specific disease, in this case Sickle Cell Disease (SCD). "Investigational" means that the drug is being studied. It also means that the FDA has not yet approved the drug for your type of disease. SCD is an inherited blood disorder that causes the red blood cells to change their shape from a round shape to a half-moon/crescent or sickled shape. People who have SCD have a different type of protein that carries oxygen in their blood (hemoglobin) than people without SCD. This different type of hemoglobin makes the red blood cells change into crescent shape under certain conditions. Sickle-shaped cells are a problem because they often get stuck in the blood vessels blocking the flow of blood, and cause inflammation and injury to important areas in the body. Regadenoson (trade name Lexiscan) is a drug that may prevent this inflammation and injury caused by the sickle shaped cells. This drug is approved by the FDA to be used as a fast infusion during a heart stress test in people who are unable to exercise enough to put stress on their heart by making the heart beat faster. Regadenoson has been studied as a long infusion at this dose in adults, and no safety issues have been identified (ClinicalTrials.gov Identifier: NCT01085201). This is the first study to look at patient benefit with the long infusion of the drug. This drug has been used in laboratory experiments and information from those other research studies suggests that this drug may help to protect the body from damage caused by sickle-shaped cells in this research study. In this research study, the investigators are specifically looking to see if Regadenoson is an effective treatment for pain crises and acute chest syndrome in SCD.
Oral iron supplementation (OIS) is a widely-used strategy to treat iron deficiency anemia. However, absorption of OIS is often low and response is variable. To overcome this, large doses are given but this may reduce compliance due to gastric irritation. Thus, OIS doses should be low, while maximizing absorption. The prevailing serum hepcidin concentration (SHep) is the major determinant of iron absorption and erythrocyte iron utilization. Based on limited data in humans, SHep can be increased by a single OIS dose but the duration of the increase is uncertain: it may be in the range of 24 to 96 hr. Also, there are few data on how the increase in SHep determines the absorption of further doses of oral iron. Is there a threshold SHep at which subsequent iron absorption is sharply reduced? Better understanding of this relationship would be valuable to design more effective and safer OIS regimens. Objectives: 1) Determine the duration and magnitude of the Fe induced Hepcidin rise form a single iron dose while determining its bioavailability and 2) Compare the bioavailability of a single dose to iron supplements consumed one after the other (two dosages).
The purpose of this study is to evaluate patients with pulmonary hypertension and sickle cell disease who have had multiple echocardiograms. Previous studies have shown that an elevated tricuspid jet (TR) regurgitant velocity on echo in this population is a predictor of mortality. This initial data only examined an isolated TR jet velocity. It was presumed that the mortality was related to pulmonary hypertension. It is the aim of this study to retrospectively evaluate patients who have had multiple echocardiograms and to determine if patients who had either a normalization of their TR jet velocity on a subsequent echo or had no evidence of pulmonary hypertension on right heart catheterization had a similar mortality rate to those with persistently elevated TR jet velocity.
This phase II trial studies how well lenalidomide (LEN) and eltrombopag olamine (ELT) work in treating patients with symptomatic anemia in low or intermediate myelodysplastic syndrome (MDS). Lenalidomide may stimulate the immune system in different ways and stop cancer cells from growing. Eltrombopag olamine may increase the number of white blood cells and platelets found in bone marrow or peripheral blood. Giving lenalidomide and eltrombopag olamine may be an effective treatment for myelodysplastic syndrome.
