Filter by:This study will determine whether 8 weekly monitoring of hemoglobin and iron parameters in the correction phase of NeoRecormon therapy in patients with renal anemia is as safe and effective as 4 weekly monitoring. Patients with chronic kidney disease will receive NeoRecormon at a dose aimed at achieving and maintaining a Hb level of 110-130g/L. They will be randomized into one of two schedules for monitoring hemoglobin levels and iron parameters, either 4 weekly or 8 weekly. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 inidividuals.
A high proportion of children under the age of 5 years and pregnant women in Tanzania is anaemic, particularly in areas of high malaria transmission. The symptoms of anaemia are often non-specific or absent and clinical judgement is generally insensitive in estimating Hb levels, especially in infants who are assessed by basic grade health staff. Thus while treatment for the common causes of anaemia is available, many cases are not treated due to difficulties in recognising anaemia. New diagnostic tools can increase the sensitivity of anaemia detection compared to clinical diagnosis but no studies have demonstrated their effectiveness in increasing case-detection and treatment of anaemic patients at the first level of healthcare. In addition, the costs of their use in relation to any increase in numbers of cases treated are not known and this knowledge is needed to guide public health decisions. Two methods of measuring anaemia are currently suitable for use at the first level of care; Copack Haemoglobin colour scale (HBCS) and Hemocue portable photometry. We propose to compare the effectiveness in basic health facilities of these 2 simple diagnostic tools compared to control dispensaries (current practice) in increasing rates of detection and treatment of anaemia in children under the age of 5 years and pregnant women over the course of 1 year in a cluster-randomised trial in 30 dispensaries in a malaria-endemic area of NE Tanzania.
Background: Anemia in chronic heart failure (CHF) is directly linked to increased mortality and reduced exercise capacity. The pathomechanism for the development of anemia in CHF is not well understood. Impairment of iron homeostasis is discussed to be one of the major triggers in anemia of chronic disease. Hepcidin was recently described as the central regulator of iron homeostasis. Main hypothesis: Plasma hepcidin levels are altered in anemic CHF patients compared to non anemic controls and might be a main contributing factor of anemia in CHF. Iron regulator-hypothesis High levels of cytokines in CHF patients cause up-regulation of hepcidin, which in turn leads to low iron uptake causing anemia. In this case venous hepcidin and hemoglobin concentrations should both correlate with cytokine levels. Erythropoietin regulator-hypothesis Dysregulation of the erythropoietin system results in anemia, which represses hepcidin. This leads to a negative correlation between hemoglobin and hepcidin in plasma. Methods: 100 consecutive patients diagnosed with systolic CHF will be prospectively included in the study. Iron status will be assessed and hepcidin, erythropoietin as well as interleukin-1, interleukin-6 and soluble TNF alpha receptor levels will be measured by ELISA. Patients will be followed up for one year and mortality, rehospitalization and worsening of CHF will be documented.
This 2 arm study will compare the level of anemia, and the decline in renal function, between patients receiving NeoRecormon, and those not receiving it. Patients with chronic kidney disease, stage 2-4, and not receiving dialysis, will be randomized 2:1 to a group receiving NeoRecormon (at a dose determined by the investigator to achieve and maintain an Hb level of 120-135 g/L), or to a control group not receiving NeoRecormon. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.
The purpose of this study is - To evaluate the efficacy of association of Erythropoetin (Neorecormon) and ATRA in patients with low risk myelodysplastic syndromes - To evaluate the tolerance of this treatment
The primary objectives of this study are the following: 1. To test if the proportion of participants achieving a hemoglobin value greater than or equal to 10.0 g/dL at any time point after the first dose during the study is greater than 0.8 when administered de novo darbepoetin alfa once a week (QW) for treatment of anemia in pediatric patients with chronic kidney disease receiving and not receiving dialysis, and 2. To test if the proportion of participants achieving a hemoglobin value greater than or equal to 10.0 g/dL at any time point after the first dose during the study is greater than 0.8 when administered de novo darbepoetin alfa every 2 weeks (Q2W) for treatment of anemia in pediatric patients with chronic kidney disease receiving and not receiving dialysis.
The purpose of the study is to determine whether improvement in the accessibility to iron supplement will decrease anemia rates in infants.
The purpose of this study was to determine the dose ranges of peginesatide administered intravenously or subcutaneously that maintained hemoglobin in participants on dialysis whose hemoglobin values were stable on epoetin (alfa or beta).
The purpose of this study is to show that the use of cinacalcet in patients with End Stage Renal Disease can help achieve NKF K/DOQI targets for both serum calcium and calcium phosphorous product.
Primary Objectives: 1. To determine the feasibility and toxicity of employing purine-analog based conditioning for allogeneic donor stem cell transplantation in patients with severe aplastic anemia (AA). 2. To determine the engraftment kinetics and degree of chimerism that can be achieved with this strategy.
