Active clinical trials for "Anemia"

The purpose of this prospective, randomized study was to determine the efficacy of low bacterial diet, in comparison to normal hospital diet, with gut colonization by aerobic Gram negative rods and yeasts as primary endpoint. In addition, the occurrence of infections and the total costs of hospital care were documented, in order to identify potential cost savings by the use of either diet.

Erythropoietin (EPO) is a hormone produced in the kidney. Its function is to stimulate the production of red cells in the bone marrow. The purpose of this research study is to demonstrate that the administration EPO to critically ill subjects in the intensive care unit (ICU) reduces the number of patients requiring red blood cell (RBC) transfusion as compared with placebo (a liquid without active medicine).

This study is designed to evaluate the hemoglobin response to Aranesp® (darbepoetin alfa) in black subjects (African-Americans) with chronic renal failure (CRF) receiving hemodialysis and to examine the safety profile.

To determine how long blood transfusions are needed for primary stroke prevention. Also, to determine the duration of risk associated with abnormal transcranial Doppler ultrasound (TCD) and to determine the specificity of the stroke risk model developed in STOP 1 in patients with abnormal TCD measurements.

This phase I trial evaluates the safety and feasibility of using a reduced-intensity regimen of cyclophosphamide, pentostatin, and anti-thymocyte globulin prior to a CD4+ T-cell depleted haploidentical hematopoietic cell transplant (haploHCT) for the treatment of patients with severe aplastic anemia that does not respond to treatment (refractory) or that has come back (recurrent). Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid. It may also lower the body's immune response. Pentostatin blocks a protein needed for cell growth. Anti-thymocyte globulin is an immunosuppressive drug can destroy immune cells known as T-cells. HaploHCT transfers blood-forming stem cells from a healthy partially-matched donor to a patient. Administering a regimen of cyclophosphamide, pentostatin, and anti-thymocyte globulin before haploHCT may help make room for the new, healthy cells and may reduce the risk of graft versus host disease.

Ferric pyrophosphate (FePP) is a water-insoluble, food grade iron compound used to fortify rice, infant cereals and chocolate-drink powders as it causes no organoleptic changes to the food vehicle. However, it is only of low absorption in man. Therefore, strategies to enhance the bioavailability of FePP, such as adding citrate or decreasing the particle size of FePP need to be investigated. The primary objectives of the present study are: 1) to test whether the presence of citrate in iron fortified rice with FePP results in higher iron bioavailability, and 2) to test whether the presence of citrate in the rice grain during the extrusion and cooking process results in higher iron bioavailability compared with iron-fortified rice where citrate has been added shortly before consumption. As a secondary objective the investigators will compare the absorption from different FePP combinations with a reference meal fortified with ferrous sulphate. The investigator hypothesize that the addition of citrate enhances iron absorption and that the positive effect is greater when the citrate is added during the extrusion. The investigator will conduct an iron absorption study in 20 women, 18 to 45 years old to evaluate the iron bioavailability from extruded rice fortified with 1) regular FePP, 2) regular FePP and citrate (both extruded into the rice kernels), 3) regular FePP and citrate added at the time of consumption, and 4) from normal rice fortified with ferrous sulphate at the time of consumption. Iron absorption will be measured as erythrocyte incorporation of stable iron isotopes at least 14 days after the administration of the isotopically labelled test meals. The iron absorption from the different meals within the same participant will be compared by repeated-measures ANOVA followed by a Bonferroni corrected pairwise comparison. The present study will provide important data where iron bioavailability from rice is accurately and directly measured using stable isotopic labels as absorption tracers. This direct data can be used to base decisions on the level of fortification, can potentially reduce costs and optimize iron delivery to the targeted population in iron fortification programs.

The primary objective of the study is to evaluate and compare the effect of iron isomaltoside 1000 to placebo in its ability to increase haemoglobin (Hb) in subjects with IDA when oral iron preparations are ineffective or cannot be used.

Globally, the most common cause of anemia is thought to be iron deficiency anemia (IDA). This was assumed to be the major cause of anemia in Cambodia, because Cambodian diets, which consist mainly of rice, lack iron-rich animal food sources. However, our findings from a previous study in Cambodia (a Canadian government funded study investigating multiple interventions to improve food and nutrition security) showed that IDA is almost non-existent and challenges this assumption. In a cross-sectional survey of 450 women from rural Cambodia, only 1.0% had Hb and ferritin levels indicative of IDA (Hb <120 g/L and ferritin <15 μg/L). A national survey conducted by UNICEF in 2014 found similarly low rates of IDA (Dr. Arnaud Laillou, UNICEF Cambodia). Further, other micronutrients known to be associated with anemia were also low (<3%) including folate and vitamins B12 and B6. In addition, 54% of the Prey Veng women had a genetic Hb disorder (e.g., α-thalassemias), which are inherited diseases that can result in a defective Hb structure and/or impair Hb production, either of which can reduce Hb concentration and increase the risk of anemia. Further, genetic Hb disorders cause ferritin and soluble transferrin receptor (sTfR) concentrations to increase, which reduce the diagnostic sensitivity of these biomarkers to identify IDA. In 2011, the Cambodian Ministry of Health (MOH) recommended weekly iron and folic acid (IFA) supplementation for all women of reproductive age, consistent with WHO guidelines. However, if iron deficiency is not a major cause of anemia, then at best supplementation is a waste of valuable resources and at worst could cause harm. Further, the justification for provision of multiple micronutrients among this population has not yet been proven, despite the push from some organizations such as the WHO. There is an urgent need to conduct a trial to clarify whether iron or other micronutrient deficiencies are a major cause of anemia in Cambodia. Research Objectives: To compare Hb concentration (g/L) after 12-weeks of supplementation in women to determine if iron significantly improves Hb concentration, compared to a placebo; To compare Hb concentration (g/L) across the four groups (multiple micronutrients with iron, multiple micronutrients without iron, iron alone, and placebo) after 12-weeks; and To determine which of the hematological indicators (ferritin, sTfR, reticulocyte count and hepcidin) have the strongest diagnostic ability to predict responsiveness to iron therapy after 12-weeks using receiver operating characteristic (ROC) analyses. Methods: A 2 x 2 factorial randomized controlled trial will be conducted over 12 weeks. A total of ~800 women (18-45 y) with mild or moderate anemia will be recruited and randomized to 1 of 4 groups: multiple micronutrients with iron, multiple micronutrients without iron, iron alone or placebo. Blood will be collected at baseline and at 1 and 12 weeks after the intervention and assessed for Hb, hematological biomarkers, inflammation and genetic Hb disorders. The investigators will use a general linear model to measure differences in Hb concentration across the four groups after the intervention. Receiver operating characteristic curves will be used to determine the diagnostic ability of the multiple hematological indicators to predict responsiveness to iron therapy.

The investigators hypothesized that both isomaltoside 1000 (Monofer), and oral iron preparation will be equally effective in correction of postpartum iron deficiency anemia.
