Filter by: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 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.
RATIONALE: Epoetin alfa and darbepoetin alfa may cause the body to make more red blood cells. They are used to treat anemia caused by chemotherapy in patients with cancer. PURPOSE: This randomized clinical trial is studying four different schedules of epoetin alfa or darbepoetin alfa to compare how well they work in treating patients with anemia caused by chemotherapy.
The purpose of this study is to determine the extend and the nature of anemia in school children and the correlation between anemia and schistosomiasis infections, malaria infections and/or malnutrition (iron deficiency).
This single arm study will assess the efficacy and safety of intravenous Mircera, administered with pre-filled syringes, for the treatment of anemia in patients with chronic kidney disease who are on dialysis, and who have previously received treatment with epoetin alfa or beta or darbepoetin alfa. Patients will receive monthly intravenous injections of Mircera, with the starting dose derived from the dose of epoetin alfa or beta or darbepoetin they were receiving in the week preceding study start. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.
This single arm study will determine the effects of complete anemia correction in anemic patients with end-stage renal disease currently receiving suboptimal doses of NeoRecormon. Patients on dialysis receiving NeoRecormon, and with a hemoglobin level <105g/L, will be treated with subcutaneous NeoRecormon at a dose determined by the investigator in order to reach (within 3 months) and maintain a hemoglobin level in the range of 120-135g/L. Heart function and quality of life will be measured before and after anemia correction. The anticipated time on study treatment is 3-12 months, and the target sample size is 100 individuals.
The purpose of this study was to compare the effect of epoetin alfa to preoperative autologous blood donation (PAD) on postoperative vigor (a measure of functional ability and well-being) and handgrip strength in patients undergoing hip or knee surgery.
